Mechanical Advantages of Fenestra Fig. 3 The Five Essentials of Steel Sash 1—Sufficient strength at the joint. 2—Rigidly attached, adjustable butts. 3—Weatherproof, double-contact weathering on ventilators. 4—Ventilator controls that provide efficient operation. 5—T-bar mullion insuring weathering between sash. 1—Strength at the Joint The construction of the Fenestra joint is based upon the patented inter- locking of the vertical and horizontal muntin bars of the sash, permitting them to run continuously from head to Fig. 4 Fig. 2 1. Horizontal bar with nick cut out. 2. Vertical bar with slot, ready for forming Fenestra joint. 3. Joint formed and horizontal bar inserted ready to be locked. 4. Locking wing put down into slot of horizontal bar—joint complete. sill and jamb to jamb. This inter- locking method retains thirty per cent more steel at the joint than any other method of joining. It gives the sash maximum strength against wind pres- sure and the vibrations caused by heavy machinery. The bars are solid rolled steel sections, 134’’ deep. They are ma- chine cut and fitted together with a weather-tight union, which makes welding unnecessary and reduces the possibility of corrosion. Figures 1 and 2 show the horizontal and vertical bars with the metal removed. Figure 3 shows the two bars after the vertical bar has been prepared to receive the horizontal bar. Figure 4 shows the completed joint. Note the graceful outward curve of the vertical bar. This is the distinguishing feature of Fenestra Windows. 2—Adjustable Butts All ventilators are horizontally pivoted 2 inches above the center by means of two external, adjustable, solid rolled steel butts. Every butt is composed of two members, one double riveted to the jamb bar of the ventilator and the other to the adjacent bar of the fixed portion of the sash. Each member has an ear which projects beyond the plane of the sash sage VENT BAR SASH BAR OVERLAPPING WEATHERING Horizontally Pivoted Sash FOR STAY BAR TRIPLE RIVETED TOLOILL and through which the butt bolt is fastened. This makes it easily acces- sible, and aslot in the member attached to the fixed portion of the sash permits adjustments. The butt bolt is pro- vided with a shoulder upon which the ventilator turns. Its lower part is threaded to receive a nut for the purpose of tightening the pin after adjustments have been made. This construction may be seen clearly by studying the illustration on page 3. The overlapping weathering makes the butt storm-proof. Asthe ventilator is closed, the weathering of the movable section fits down -inch over the weathering of the fixed section, forming an overlap which sheds water and gives surface contact. 3—Ventilator Weathering Two-point, flat-contact weathering is used on all types of Fenestra Venti- Mitered weathering at the sill lators. At the head and sill, where extra heavy sections are used to STAY BAR strengthen the ventilators and prevent sagging, the weathering members have long down-standing legs that form a drip on the exterior. On the interior of the sash, long legs project upward, thus forming a double contact. Further protection is given by the turned-down lip on the interior of the head weather- ing member that forms a baffle for air currents. This feature may be seen by studying the head details on pages 11, 12 and 18. To guard against leakage at the sill, the weathering member on the sash is mitered and turned at a right angle, all seepage being thus eliminated. Any water which may collect from condensation is carried to the outside through weep holes cut in the sill member of the fixed portion of the sash. 4—Ventilator Controls Fenestra operating hardware is at- tached to the ventilator by the Z-bar bracket. This is a solid steel section rolled with a fillet in each corner which gives it double thickness at this point and, therefore, greater strength than can be obtained in any other way. The bracket is securely attached to the bottom section of the ventilator by means of three rivets and cannot work loose. It is punched for either of the standard operating devices. Engineers and architects have de- manded a self-operating and fool-proof method of locking ventilators in place. This demand has been supplied in the Fenestra cam latch, which is of pleasing design, strong and substantial, and is attached to the solid rolled steel Z-bar bracket, which is securely riveted to the bottom rail of the ventilator. In closing the ventilator, the cam ZLo-BAR BRACKET latch rides up over the weathering and falls inside, locking the window, as shown in the illustration. The cam latch and stay is supplied as standard on Fenestra Sidewall Sash. To open the ventilator, the cam latch is lifted by the right hand, while the left hand pushes the stay outward until one of the notches along its lower edge engages the weathering at the bottom of the ventilator. The cam latch and chain are supplied when specified on Fenestra Standard Sash. The chain extends from the handle of the cam latch over a pulley at the top of the ventilator down to within easy reach and back to the handle of the cam latch. Cam latch and chain A slight pull releases the cam latch and at the same time pulls the ventila- tor open. A chain cleat, fastened to the sash or to the wall below the window, engages the chain and holds the window open. KR ti ago eeage 103 7 SASH D/MENS/ON ©6- Mechanical Operator Fenestra Worm and Gear and Fenestra Tension operating devices are designed particularly for the control of ventilators in sidewall sash that are not accessible from the floor. Complete details and description of ~ these operating devices will be found under ‘“‘Operators”’ in this catalog. If desired, our Service Department, the Fenestra Construction Company, will erect both sash and operator and guarantee a satisfactory installation. leq W/DTH OF OPENING /2-32 Horizontally Pivoted Sash 3 SASH DIMENS/ON 6-04 5—The T-Bar Mullion 7H" 5. 2 at aaa 7,3 SASH DIMENSION 6°07 [43 43._ /49 148 te When two or more Fenestra windows are used in the same opening, they are tA +i+ os Sees aes ee held together in the center by means of our standard T-Bar Mullion.

It has been our privilege, based on 15 years’ experience in unusual day- lighting and ventilating problems, to make suggestions that have increased the efficiency of proposed buildings very materially. The Showers Building shows the effective lighting and ventilating of a large floor area—double monitors with V-shaped roofs supplement the sidewalls to provide efficient working conditions. Scores of short saw teeth running crosswise of the building flank the central monitor in the Dodge plant— a model arrangement of lighting and ventilating units. These are typical of scores of buildings where the experience of daylighting engineers has been of assistance in working out econom- ical and effective designs. Where service of this kind is de- sired, our Engineering Department is at your command without obligation. Horizontally Pivoted Sash Fenestra Warehouse Types , ine 1p MEIGHAT S HOW FENESTRA IS INDICATED 2 PANES For brevity, letters are used to represent a in élass sizes as follows: Y—12" x 18”; Z—14” x 20”. Each type of sash is designated by a mae number. The first digit designates num- ee ber of lights wide; second digit, number of fa lights high. If sash is ventilated, the 23/4/ third digit indicates number of vents; the fourth digit, the number of lights in vent; and the fifth digit indicates number of 4 PANES lights between sill of sash and sill of 62 96" ventilator. For example, a Z—54161 sash Z 670% means a unit for 14” x 20” glass, 5 panes 54 wide, 4 panes high; 1 vent with 6 lights, sill of vent 1 pane above sill of sash.

Saves Time and Money Certain popular types of Fenestra Solid Steel Windows have been stand- ardized. These are made in quantities and carried in stock in Detroit and in other cities ready to supply rush de- mand. They are made from standard material to accommodate 12” x 18” and 14” x 20” glass exclusively. They are fully equipped and can be shipped quicker than any other windows. We recommend sash in 14”’ x 20” glass size, as they cost less per square foot than the 12’ x 18’ type. They answer all the usual building needs. An ideal building from the standpoint of sash economy is one designed for Warehouse Stock Sash exclusively. If this cannot be done, use Warehouse Stock Sash wherever possible, and give Standard Sash the next preference. We shall be glad to give you the address of the warehouse nearest you. How to Use the Table Suppose you have a window opening 7’ high by approximately 15’ wide to be filled with stock sash. You want to know the number of units needed, their height and width, and the number of mullions necessary. You probably would use the 14” x 20” size, if possible, because the larger glass size reduces the cost of the sash per square foot. In the column headed “Glass Size 14” x 20’,’’ you will find a height dimension of 6’ 1034’’—this is probably close enough to 7’ to serve your purpose. Glancing down the same column you find an over-all width dimension of 14’ 111%”, and opposite this figure, in column three, you find the number 12, which means that the bay of sash when complete will be 12 lights wide. In the next column, the figure 3 indicates that you will need three units of sash and therefore two mullions to join them together. The last column gives the figures 4, 4, 4, which indicate that each of the units will be four panes wide. Therefore you will want to use three units of Z-44181 Fenestra Sash and two Z-4 mullions. Ventilator Lights Cut Down Ventilator lights that abut on the top, on the sides or on the bottom of the ventilator, must be trimmed one inch (1’’) along the abutting edge. Care should be used to see that the glass is cut full to the dimensions specified. The picture shows a standard glass lay- out for a “Z”’ type sash—one that will accommodate glass 14” x 20”.

Prepared Openings (Page 10) We strongly recommend the installation of Fenestra Sidewall Sash after the walls of the building are practically completed. In every case, regardless of whether single units or combinations of units are to be used, the opening should be prepared in accordance with the dimensions shown in the installation details on the following pages. Re- bates and angles are shown that have been accepted by builders and contractors as the best building practices, and these should be closely followed. It is not good practice to place the sash upon the sill and then construct the walls around them. Long experi- ence of engineers and builders familiar with the erection of steel sash has proved this method unsatisfactory. Regardless of the care and refinement used in adjusting such installations, they are frequently faulty. Fenestra Erection Service The Fenestra Construction Company, a subsidiary of the Detroit Steel Products Company, offers architects, engineers, contractors and building owners, the service of an organization especially equipped and trained for the erection of Fenestra WindoWalls. Under separate contract, the Fenestra Construction Company will assume complete responsibility for the shipment, handling and erection of Fenestra products, from the time they are manufactured until they are installed in the building. Glazing Fenestra Sash All Fenestra Sidewall Sash should be bed _ puttied, then the glass inserted and held by means of Fenestra spring glazing clips. Clips are supplied, 4 for each fixed light, and 6 for each ventilator light. They are put in place with the putty knife, as shown in the illustration, after which the sash is face puttied. Note—When inserting glazing clips, first place the clip against the glass, then spring the free end into the hole provided for it.

All runs shall have one-foot stationary panels at the ends and two-foot stationary panels between swing sections, all as shown on engineer’s details. All sash members shall be solid rolled steel sections of standard Fenestra design. All vertical muntin bars shall be substantially riveted to the top and bottom rails of the sash. All sash shall be hung by means of malleable iron butts, with 3” pins, placed inside of girts and spaced four feet (4’-0’’) on centers. All glass shall be held in place by Fenestra angle glazing clips, located near the top and bottom of each side of each light. All glazing shall be done under another contract. All sash shall be given one coat of red mineral paint before shipment. All Continuous Steel Sash shall.be installed in the building by the sash contractor. All flashing shall be done under another contract. Monitor Sash Fenestra Continuous Sash is designed for use in monitor and saw-tooth roof construction where the plane of the windows is onaslope. It may also be used in vertical planes, where the builder desires this form of window. The chief advantage of this construc- tion lies in the fact that it provides easily and rapidly a continuous open- ing from one end of a building to the other, at the same time furnishing a canopy of glass and steel which protects the aperture against weather. Construction All Fenestra Continuous Sash are made from solid rolled steel sections. The head member is a special angle. The sill is a rolled section of special Fenestra design, with a long down- standing leg, bent at the end to make close contact with the building con- struction. The intermediate muntins are T- bars, and the members forming the ends of the units are special angles. All members of the sash are accurately fitted and strongly riveted at the joints to form a standard panel, these panels being joined end to end when erected in the building, to form one continuous, unbroken sash of almost any desired height or length. Riveted assembly insures a strong, tight, positive joining of members, with sufficient flexibility to withstand un- usual strain without the danger of Weep holes are pro- vided in the sill member, to prevent water from collect- ing at the bottom of the sash and seeping through. 17 Fenestra Continuous Sash showing angle section at the head, specially rolled sec- tion at the sill and intermediate T-bar muntins with slots for glazing clips. Two to three slots are pro- vided in each muntin. This construction is the same on all types of Fenestra Continu- ous Sash. Monitor Sash Figure 1 End condition for a continuous run. Notice the storm panels and the 1’ stationary end panels between the ventilating sections and the build- ing construction. Storm panels are furnished as an extra where desired. cracking or breaking due to an uncer- tain weld. A specially designed weathering cap at the end of each run overlaps and fits around the edges of the ventilating and the fixed sections, allowing for expan- sion and contraction in the sash while providing thorough weather protection and reducing heat losses. Standard Heights Fenestra Continuous Sash is manu- factured in four heights, these being standard whether the sash are Top Hung, Center Pivoted or Fixed. These heights are: 3’, 4’, 5’ and 6’. Sash of special height may be secured where desired, but naturally require longer to manufacture and can be supplied only at an increased price. Standard Widths Standard units of Fenestra Con- tinuous Sash measure 20 feet in length, the dimension points being equal to the clear opening. Smaller units may be used in widths varying by 2’, as for instance, 8’, 10’, 12’, 14’, 16’ and 18’. We have found, however, that in the vast majority of cases, 8’, 12’ and 20’ widths answer all purposes. These widths provide for the economical arrangement of operator arms and per- mit the punching of steel work on even 4’ 0’ centers for butt attachment before it is erected in the building. Units coming at the end of arun take the same standard widths, but include a 1’ fixed panel. Thus a 20’ unit coming at the end of a run would be composed of a 1’ fixed section and a 19’ ventilating section. No odd-inch dimensions, such as 16’ 6”, are used. Joining Standard Units Where two or more units of Fenestra Continuous Sash are joined to form one continuous run, the joint is always made beneath the center of a glass light and is thus absolutely weathered without the employment of weathering caps. Gusset plates, which follow the contour of the sash bars, are used at both head and sill. Weathering Members At the ends of all swing sections, stationary panels one foot wide are in- stalled. These panels are shown in the picture at the left of this page and are standard, whether the sash are Top Hung, Center Pivoted or Fixed. The end panels afford the best means of effecting a weather-proof connection between the sash and the building, allowing for minor irregularities in structural work around the prepared sash openings. Between all swing sections a two-foot stationary center panel is installed, as shown in the picture at the right. This panel, which is standard on all types of Fenestra Continuous Sash, al- lows ample clearance for structural members that may interfere with the operation of swing units. The union of the stationary and swing units is made weather proof by means of a channel section which com- pletely covers the joint when sash is closed. On Top Hung Sash this weathering channel is bolted to the swinging portion as shown in the pic- tures above. Where Center Pivoted Sash is used, the weathering cap is hinged at the top and swings outward as the sash pivots. A guide clip, pro- truding from the sill member of the sash, slides in a channel under the cap, assuring alignment. This is shown on page 31. Figure 2 Here are the 2’ center panels installed between swing sections of Continuous Sash. Notice the storm panels and the weathering members on the ends of swing sections. Flashing Although Fenestra Continuous Sash is well weathered, flashing should not be omitted. Detroit Steel Products Company does not furnish or install flashing, roof, nor collateral steel work. This material should be furnished as part of the building construction. To assist the architect and engineer, details of the most approved methods of flashing Fenestra Continuous Sash are shown in the installation details on the following pages. Fenestra Continuous Fixed Sash Fenestra Continuous Fixed Sash is of similar construction to Top Hung Sash, except that the hinges at the top are omitted and no operating mech- anism is supplied. In place of the hinges, angle clips (Part 619) are supplied with the sash for use at the head, these being bolted directly to the building construction as shown on page 26. At the sill, Part 433 clips (also shown on page 26) are supplied without extra charge, these being bent around the steel work to hold the sash tight against the building construction. Glazing All Fenestra Continuous Sash are glazed from the outside. One-quarter- inch, ribbed, wire glass is recommended, the ribs running vertically. The glass must be firmly imbedded in steel sash putty, after which Fenestra angle glazing clips are bolted to the muntin bars at the sides of each light. The following table shows the glass sizes for standard units of Fenestra Continuous Sash: Sash Glass Glass Height Width Height SU 23144" 2’-914"" AZO 234%" 3/-914”’ 5/-0”" 2314" 4-94" 6’-0” 231%" 5/-914"" Fenestra Continuous Operator The selection of a properly designed operating device is just as important for the satisfactory installation of Con- tinuous Sash as is the selection of the sash itself. Many a builder has been disappointed in his ventilating scheme because, after everything was done, he found the operator would not push out the sash to provide the necessary open- ing. Fenestra Continuous Operator is the product of the careful design and long experiment on the part of our engineers. It combines the principle of ‘‘straight- line motion” and therefore maximum power, with a design by which this power increases faster than the load increases. These features, coupled with the refinements and improvements which have been put into effect within the past few months, make the Fenes- tra Continuous Operator an important factor in the satisfactory solution of any Continuous Sash problem. Details of Fenestra Continuous as well as Fenestra Worm and Gear Oper- ators will be found on pages 39 to 56 of this catalog. Erecting Continuous Sash All monitor construction is a movable roof and only men experienced in the erection of steel sash and operator can satisfactorily install it. The Detroit Steel Products Company saw the need for a specialized erection service and organized the Fenestra Construction Company to supply it. This is the first organization built up Monitor Sash Method of glazing Fenestra Continuous Sash with angle glazing clips bolted through the vertical T-bar muntins. The upper runs of sash are Top Hung, while the lower run is Fixed. The face putty had not been applied when this picture was taken. by any sash manufacturer to assure acceptable installations for customers. Branch offices are maintained at Detroit, New York, Philadelphia, Boston, Hartford, Buffalo, Chicago, San Francisco, and Birmingham, From these, erection service can be extended to take care of almost every builder’s needs. These offices are equipped to follow shipments, look after prompt delivery at the building, install sash, erect oper- ator, and attend to every detail. It is to our advantage to be sure that a8) our materials are not only made cor- rectly but installed correctly, and we are ready to assume the responsibility that such a service implies. Our con- struction men are all experts in the erection of steel windows, and can therefore relieve both owner and con- tractor of detailed supervision. When Fenestra Service and Fenestra Solid Steel Windows are specified, the customer can forget that part of the building and be sure of satisfaction when the completed work is turned over. Fenestra is more than a name; it isa guarantee of complete window service.

Top Hung vs. Center Pivoted Continuous Sash The use of Top Hung Continuous Sash or Center. Pivoted Continuous Sash should depend entirely on the nature of the building and the activities it covers. Both types have advan- tages and disadvantages. Top Hung Sash requires less expen- sive collateral steel work and’ provides protection from weather. On _ the other hand its construction is such that it cannot providé a 100% open- ing, while the weight on the operator necessitates either a longer period for opening and closing or the in- stallation of more expensive operating mechanism. We seldom recommend the use of Top Hung Sash in vertical plains, either in roof or in sidewall construction. Center Pivoted Sash requires a can- tilever support, which issomewhat more expensive than that required with Top Hung Sash, and its proper alignment requires care.

FENESTR A CONT/NUOUS TOP HUNG SASH Monitor Sash Top Hung Continuous Sash Sak Designed by the Company’s Engineers This type of Continuous Sash is most frequently used in monitor or saw- tooth roof construction where the plane of the sash is off the vertical. It is also employed in sidewalls where the builder particularly desires this type of construction. It is hinged at the top under the pro- tecting hood of a Z-bar or angle section Commonwealth Steel Co., St. Louis, Mo. and swings out at the bottom to form a weather-protecting canopy of glass and steel. Heavy malleable iron butts, spaced 4’ 0” on centers, are attached on the inside of the building construction and are thus protected from weather. The swinging section overlaps a 2’ glass storm panel at each end of the run. This type of Continuous Sash can be installed in runs of practically any desired height and length. The swing- ing section is opened and closed by Fen- estra Continuous Operator, manually or electrically controlled. (For details of Fenestra Operators, see pages 37 to 54.) Contractors, W. M.

Three decks of Fenestra Continuous Top Hung Sash in the valley roofs, and two decks along the top of the sidewalls above the cranes, provide exceptional light and ventilation in this steel tubes mill. Seventy thousand square feet of sash were used. “We draw our labor from men who are used to the modern working conditions of automobile plants,”’ says Mr. R. H.

Ninety-one thousand six hundred and seven square feet of Top Hung Sash light and ventilate this mammoth machine shop. The swing sections are operated by Fenestra Continuous Operators, the units of the monitors being electrically controlled. The glass canopy, formed when the sash are opened, makes it unnecessary to close the windows during inclement weather. Fenestra Continuous Top Hung Sash is also used in the bays of the sidewall, the upper three tiers being fixed, while the lower four tiers are manually operated by the use of auxiliary powers, three bays being operated froma single station. Some idea of the size of this building may be gained from a glance at the single doors which give access to the building directly under the big bays of sash.

This company figures that Fenestra WindoWalls and Continuous Sash, such as used on this building, give a saving of $5,000 a year as compared to the same building equipped with wood sash. This saving includes economy in repairs, depreciation, illumi- nating cost, and labor turn-over, in addition to the advantages derived from fire protection and increased production due to better light and ventilation. Over 10,600 square feet of Fenestra Continuous Top Hung Sash were used in the monitors alone. Contractors, Morava Construction Company National Malleable Castings Co., Chicago, III. The Akin roof as used here is an economical design, particularly where a crane runs the full length of the building and where evenly distributed daylight is desired over a large floor area. The Fenestra Top Hung Continuous Sash in both monitors and sidewalls forms a canopy of glass which makes it possible for the windows to remain open even in stormy weather. 23 Monitor Sash re 24 y; FOR?

Fenestra Horizontally Rolling Monitor Sash used both in the monitor and in the sidewalls. Horizontally Rolling Monitor Sash In rolling mills, steel mills and other structures of this character, Horizon- tally Rolling Monitor Sash are some- times desired, these buildings being of semi-open construction where free and continuous circulation of air is all- important. These sash are of the Fenestra side- wall type, fixed light sash being mount- ed on substantial rollers and operated either by hand or by mechanical operators. The usual construction is to have the sash alternately movable and fixed, the movable units sliding past the fixed units to provide a 50% monitor opening. Weathering strips riveted to the jamb bars provide baffle weathering between movable and fixed sections. The sash as described above are run continuously along the monitor, the steel details being especially arranged for this type of construction. Bottom Hung Continuous Sash Where forging, foundry work or heat treating is handled under acomparative- ly low roof, the need for rapid changes of air becomes imperative. Under Bottom Hung Continuous Monitor Sash in saw-tooth roof construction. The operating device is in just the reverse position from that occupied when used with Top Hung Continuous Sash, the arms pull in from the top in- stead of pushing out from the bottom. 39 Monitor Sash Architects, Sargent & Lundy Contractor, The Foundation Co. North East Station, Kansas City Power & Light Company Two runs of Fenestra Tension Operator are used to open and close these unusually large vertically pivoted ventilators. Each ventilator is connected to both operators, one at the top and one at the bottom. The lower operator is directly connected to the power (shown about half way down the run), while the upper operator is handled by means of an auxiliary power as described on page 43. such circumstances we sometimes have installed continuous sash hung at the bottom and opening out at the top. Weathering under such conditions is, of course, imperfect; but the character of the work performed in such a build- ing is usually such that slight leakage is not important. On the other hand, the sash opening out from the top provides an outlet almost straight upward and creates a draft almost like that in a chimney. As a means of ridding a wide, low build- ing of smoke, heat or gas, it is the most practical of all monitor types. The question of light should also be considered. Monitor sash is usually washed infrequently, with the result that even when the sash is open the amount of light is seriously reduced. Top Hung Sash is the worst in this respect because it opens the least. Center Pivoted Sash, opening wider, lets in more light, but Bottom Hung gives a clean, wide opening with the sky as the limit. While the general construction and operation of the sash are like that of other Fenestra Continuous units, Bot- tom Hung Sash is not standard. Special angle sections are required at head and sill and extra flashing is necessary at the head. Where sash of this type is desired, we suggest that the designer consult with our nearest Sales Engineer or write to Detroit for suggestions and details. Vertically Pivoted Monitor Sash Vertically pivoted sash, although sometimes used in side walls, is adapted 36 chiefly for monitors where it may be controlled in long runs by means of Fenestra Tension Operator. It has an advantage in that it may be swung in an arc of 180 degrees to take advantage of air currents from almost any direc- tion. This type of sash is not recommended where weathering is of first importance, inasmuch as the sash, when open, affords little protection from driving storms. For foundries, and mill buildings its use is entirely satisfactory and it has been standardized for monitor con- struction by some of the largest cor- porations of this kind. The sash themselves are of the Fenestra sidewall type, ventilators being pivoted in the center at top and bottom. nestr Operating Devices Mechanical Operating Devices | fe is not economy to try to adapt one type of operator to all designs of sash. For instance: In Center Pivoted Sash, the load on the operator is greatest at the beginning of the operation and least at the end. In Top Hung Continuous Sash, the load is least at the beginning of the operation and greatest at the end. Operator designed for one is not necessarily fitted to operate the other. Fenestra Operating Devices, therefore, are built each for the particular work it is intended to perform. Each is guaranteed to perform that work satisfactorily. More than that, Fenestra operators are built for direct and immediate action, easy operation and economy of power. Operating arms are designed to give greatest leverage at the point where the load is heaviest. In offering these devices to the public, therefore, we feel that they uphold in every way the integrity of design, material and workmanship which has always been a Fenestra characteristic. Fenestra Operating Devices are of three kinds: 1—Fenestra Continuous Operator for Fenestra Continuous Sash either on the vertical or on a slope. 2—Fenestra Worm and Gear Operator for Horizontally Pivoted Sidewall Sash. 3—Fenestra Tension Operator designed par- ticularly for long runs where Pivoted Sidewall Sash is used. Each of these three types is described in detail in the pages following. 1—Fenestra Continuous Operator Specifications Mechanical Operator to be of Fenestra Continuous or other straight-line type, to be approved by engineers. The worm and gear shall be of machine-cut steel, oil encased. Worm to be equipped with thrust bearings and positive stop. Tension line shall be of 1” wrought iron pipe. Power to be located near the end of the run, properly anchored by means of 14” rods and turnbuckles. An Fenestra Continuous Operator is designed with four distinct advantages in mind. 1—To open and close the movable sections rapidly. 2—To insure an easy pull on the ' chain. CNS. ° ! ‘ % 3—To operate, from a _ single | AN . . . a aN power, individual or KS multiple banks of sash in long runs, located either in vertical or in sloping planes. 4—To assure as wide an opening as possible. Direction of force Two basic principles have been em- ployed by our engineers, these principles — Fixed pout ¢ Pipe travels being exclusive in Fenestra Contin- uous Operator design. 1—Power applied to the sash in a straight line. Line of the sash 37 endless chain shall extend downward from the power, along the column or wall, to the point of operation. Operator arms shall be of steel angles. Tension line supports shall be solid steel angles, solidly anchored to the building construction and carrying housed rollers to support the pipe. Operator is to be erected by the manufacturer and left in complete working order. 2—Power increasing faster than the load. How these principles are utilized is best explained by a description of the device itself. Design Fenestra Continuous Operator con- sists of a high-grade tool steel worm and a worm gear power, oil immersed and operated by a chain running over a chain wheel on the same shaft as the worm. This mechanism transfers a pull on the chain through a steel rack and pinion to a sliding pipe, which operates levers that in turn open the sash. The levers consist of two arms (AD — Operating Devices Power for Fenestra Continuous Operator, showing chain wheel, chain guard, rack and tension line. Note the wide power supports, and the wide bearing surface provided for both the worm shaft and the gear shaft. The specially designed Fenestra stop is shown on the worm shaft at the opposite end from the chain wheel. and CB), one twice as long as the other. The long arm is pivoted to the pipe at one end (D) and to the sash at the other (A). One end of the short arm is pivoted to the center of the long arm (B) and the other is pivoted to a pipe roller housing (C), which is held rigidly to the building. The short lever, pivoted at points C and B, takes all of the side thrust from the long lever, leaving the point A to exert a force only in the direction of the travel of the sash. The mech- anism is really a parallel motion de- vice, and as such eliminates so-called “motion around the corner’’ and ap- plies its power in an absolute straight line (CA). That the power increases as the mech- anism is operated is made evident by considering the long lever as a simple strut, with the point A resting against a wall and lifting a load, while the point D rests on the floor. If rollers were attached at the points A and D, so that they could roll along both the wall and floor, it is evident that the closer the point D approached the wall, or in other words the more perpendicular the strut became, the easier it would be to lift the load. The Fenestra transmission, therefore, provides a simple, efficient power line free from compounding levers and counterweights. It has fewer parts than any other steel sash operator on the market, with the corresponding ease of maintenance and freedom from friction. It exerts a direct action on the sash in the absolute direction of travel, thereby securing maximum power with the minimum effort, the power increasing faster than the load. Any of our engineers or sales repre- sentatives will be glad to present samples for the criticism of your me- chanical engineer or will refer you to installations where the durability and superiority of our device has been thoroughly tested and proved. Details of Operator Construction The Power The Fenestra power consists of a worm and gear, both machine cut and both protected from dust by an oil- filled case. The steel gear is provided with straight-face, machine-cut teeth and extra heavy hub and rim. It fits tightly over a 1’ squared solid steel shaft, which also drives a pinion i mesh with the rack. ; Gear and pinion are separated by a spacer, and all three are broached out to fit over the shaft so tightly and ac- curately that they have the reliability of a single piece. The machine-cut worm and shaft are of one piece of high carbon steel of un- usual tensile strength. They are turned down from one solid bar, and are pro- vided with ball thrust bearings to over- come friction. The shaft extends 4’ beyond the case and is squared at the end, to receive the chain wheel, which is broached to fit accurately, and is held in place by a 14” cut set-screw and a cotter-pin. Thus, for all practical purposes, the Operating Devices Unretouched photograph of Fenestra Continuous Operator used with 6’ high Top Hung Continuous Sash. Note the position of the solid rolled steel lever arms as described on page 40 and the location of tension line supports described on page 42. driving mechanism of this operator is a single solid steel unit, absolutely reliable. The power case is especially designed to provide an unusually long bearing surface for the drive shaft. This un- usual length is a guard against binding and an insurance of easy operation as the gear is held absolutely in alignment. The operator automatically locks the sash in any position, when open. The power is not shown in this picture. Power Supports The power is supported by two wide brackets especially designed to with- stand great lateral pressure. Each one of these is attached to the building construction by 14”’ bolts. The outer ends of the brackets are trussed with 1’ tension rods equipped with turn- buckles, which insure permanent and absolute rigidity. The Chain Guard The Fenestra Chain Guard is sus- pended from the same shaft as the chain wheel, between the wheel itself and the power case. The chain, therefore, may be pulled from any position without fear of its jumping from the chain wheel. The Rack The Rack is in keeping with the care- ful design and workmanship of the Operating Devices Detail view of Continuous Operator tension line supports, method of pivoting short lever arm to roller housing and roller support for tension line. Note slotted holes to provide for in-and-out adjustment of pipe roller and bracket. the tension line. Slotted punching is arranged to provide for slight adjust- They are bolted solidly to the building construction and carry at their outer power, being of high tension solid steel of stub-tooth design, machine cut. The Tension Line The tension line is of 1’ wrought iron pipe, supplied in 20’ lengths, with junction points reinforced by solid steel plugs put in with a drive fit and riveted in two directions. This tension line, by actual test, will support a load of over 15,000 pounds. The lever arms are solid rolled steel angles, giving maximum strength, and are equipped with universal joints at all points of attachment. Fittings are all designed to reduce friction and give easy and free operation. The Stop In place of the old-fashioned stop bars, which halt the movement of the tension line without eliminating the power, the Fenestra stop is of special design, one part being broached to fit over the worm shaft at the opposite end from the chain wheel. As the sash closes, the component part of this lock comes into mesh, locking the shaft and preventing the worm from func- tioning. Thus the worm is prevented from developing further power and all strain on the rest of the mechanism is there- fore eliminated. Bronze Bushings Bronze bushings are used at all universal joints. Tension Line Supports These consist of 2’’ x 3” solid steel angles, with the short leg turned down. ends the roller housings which support ment of the operator. How to Determine the Proper Width of Opening and Length of Runs The real usefulness of any operating device depends on its ability to pro- vide a sufficient opening rapidly and easily under any and all conditions. Fenestra Continuous Operator is designed to do just that. To provide such an operator, the manufacturer must, of necessity, de- sign it to suit the individual job. He must know, for instance, such details as these: 1. Is the sash top hung or center pivoted? 2. Is the sash on the vertical or on a slope? If on aslope, what is the pitch? How high is the sash? How long a run is to be oper- ated from each power? 6. What pull on the chain is desirable? 7. Are idlers to be used? how many? If so, Any of these details may be varied to meet the needs of the individual building. In fact, they are largely a matter of selection on the part of the builder, and in this selection we are always glad to give assistance and ad- vice. It must be kept in mind, how- 40 ever, that some details must always be of more importance than others. To say that Fenestra, or any other operator, will provide a definite open- ing or operate a definite length of run without regard to these varying con- ditions is to make a statement that cannot be other than misleading. For example: Two hundred and twenty-five feet of Fenestra 3’ high, Top Hung Continuous Sash, on a 15° slope, can be opened 34” in 24% to 3 minutes, with an easy pull on the chain; but if the same sash were placed on a 45° slope, or if the sash were 4’ high or 5’ high, the time of operation would have to be longer, or the runs would have to be shorter, the pull harder, or the width of opening less. On the other hand, if Center Pivoted Continuous Sash were used, the runs could be longer, the width of opening greater, the pull easier, and the time of operation shorter. The length of run to be operated from one power is usually determined by the type of building and the manu- facturing processes it covers. Where the building is of considerable size and houses only one general type of work, it is frequently advisable to operate the sash from one power, as this saves time and insures uniform ventilation throughout. But a building may house several departments, as, for instance, a foundry with a molding floor, a pattern shop and a machine shop all under one roof. Under these conditions the runs are usually operated from several stations, as the men on the molding floor might want maximum ventilation while pour- ing, while the men in the pattern shop and machine shop would be most un- comfortable in such a draft. For flex- ibility in the control of ventilation, therefore, short runs are always pref- erable. Fenestra Continuous Operator will solve the problems on any type of in- stallation. It will provide wide open- ings or operate long runs from a single power, and will perform its work with more rapidity and greater ease than any other operator on the market. In operator design, as in sash design, it is the aim of Fenestra engineers to supply the type of material that will give the results desired under the con- ditions prevailing. Erection The Fenestra Construction Company erects all Fenestra Continuous Opera- tors. This isa highly specialized mech- anism, requiring skilled erection, and the Detroit Steel Products Company is not responsible for its satisfactory installation unless it is handled by our own Service Department. Branch offices are maintained in Detroit, New York, Philadelphia, Boston, Chicago, Birmingham, and San Francisco for this particular service. These offices follow shipments, attend to prompt delivery of material at the building site, see that it is properly installed and, in short, take over all the details. Details Required with Orders To insure an economical and practi- cal installation of Fenestra Operator, it is necessary that our Engineering Department have certain information before the order is entered in the shop. Floor plans and drawings, showing elevations and sections of the buildings, are necessary, so that the operator ten- sion pipe will not be designed to run through wide pilasters, heavy concrete or steel columns, gusset plates, etc. Structural steel details—that is, shop steel drawings—are necessary to show where operator supports may be at- tached. Crane details are necessary, partic- a / anes Operating Devices Fenestra Continuous Operator with auxiliary powers, used on Top Hung Con- tinuous Sash in the sidewalls of the U. S. Armorplate Plant, Charleston, W. Va. The first and third banks of sash are operated by powers directly connected, while the second and fourth banks are operated by auxiliaries as described below under ‘‘Operating Multiple Runs.”’ ularly the distance between the columns and the crane bridge. This is essential in order that the operator may be laid out to clear the crane mechanism. It is also important that we have the distance from the inside face of the sash to the inside face of the wall or steel work. In addition to these details, the an- swers to the questions under ‘‘Width of Openings and Length of Runs’”’ should be determined at the time the order is taken. Operating Multiple Runs Where it is desired to operate several runs or banks of continuous sash from one power station, a sprocket wheel, moving with the main power, is con- nected to a similar sprocket, which is in mesh with a rack on each of the other runs of sash. This auxiliary power device is shown in the picture at the top of this page. Here, again, the width of opening and the length of each run is dependent on varying conditions as outlined above. Special Uses for Fenestra Operators The simplicity and direct action of Fenestra operating devices make them easily adaptable to varying conditions. The Tension Operator, described on pages 53 and 54, has been used suc- cessfully with auxiliary powers to operate large bays, containing many banks of ventilators one above another. Vertically pivoted ventilators and horizontally rolling sash are easily handled by means of Continuous Operator or Tension Operator, see pages 35 and 36. Fenestra Continuous Operator is also adapted to use with a somewhat unusual construction, where continuous sash are hinged at the bottom to open out at the top, see pages 35 and 36. This has the ad- vantage of providing maximum ventila- tion at a point where this is essential, but where weathering is of secondary consideration. The flexibility of the Fenestra tension device permits a variety of operator designs, in which our engineers are al- ways glad to assist without obligation to the customer.

Operating Devices Fenestra Electrically Controlled Operator Power for Fenestra Continuous Operator, with the electric motor attachments. A gear and sprocket replace the chain wheel of the manually operated power. Fenestra Electrically Controlled Operator is designed to open and close large areas of Continuous Sash from one centrally located station with a mini- mum of effort. This station may be located at any desired point in the building where, by pressing a button, the ventilating portion of an entire roof or sidewall may be op- erated easily and quickly by one man, Where ventilation is required over a large floor area, it is frequently desir- able to centralize the responsibility in one person. In such cases, a Fenestra Electrically Controlled Operator is ideal. One of the best installations is in the Government armorplate plant at Charleston, W. Va. Other interesting installations may be found in the National Tube Co., Lorain, Ohio, plant; the Bevo plant of the Anheuser-Busch Co. and the Commonwealth Steel Com- pany in St. Louis, Mo.; the Government dirigible balloon hangars at Lakehurst and Cape May, N. J.; the General Fireproofing Company’s building, at Warren, Ohio; the Samson Tractor Co., Janesville, Wis.; and the Williams- burg Power House in Brooklyn, N. Y. Details of Construction Our standard equipment for electri- 4 cally control- led operator includes mo- tor, control panel, double action limit switch and push button station. This material is erect- ed in place by our service department, The Fenes- tra Construction Co., ready to be connected up by the electrical con- tractor. A specially designed power is pro- vided to which the motor and limit switch are rigidly attached, forming one complete power unit. The drive con- sists of silent chain and sprockets. A high torque motor of special design operating on 220 or 440 volt, 60 cycle, 3 phase alternating current is recom- mended. Direct current motors are not carried in stock, but if alternating current is not available, we can furnish at slight additional expense a special motor for 230 volt direct. Naturally a little longer is required for delivery. We do not recommend alternating nor This is a typical control station for a monitor containing three runs of Top Hung Sash on either side. Pressing the upper button of the center right- hand panel opens the center run of sash on the left-hand side of the moni- tor. Pressing the center button stops the sash at any opened position, while pressing the lower button closes the sash. 47 direct current motors other than above. The standard motor control panel is enclosed in a steel case and is designed to control the opening and closing of the sash, also for the purpose of starting and stopping the operation at inter- mediate points. = LIMIT SW/TCH BY D.S.P Co.

This largest single room structure in the world is 1,066 feet long, 350 feet wide and 200 feet high. There are more than 100,000 square feet of Fenestra Steel Windows, with electrically controlled operators. Both sash and operator were designed by the Fenestra engineers. The sash are glazed with actinic glass to eliminate the ultra-violet rays which have a deteriorating effect upon the balloon fabric. One can realize the size of the building by noting the automobiles in front. The limit switch of rugged enclosed construction forms an integral part of the power unit and is located in a convenient position, making all parts accessible. The action of this switch is positive. It can be adjusted with precision to automatically limit the movement of the sash in either di- rection. The push button station is of heavy iron construction and is de- signed to resist hard usage. The but- tons are so arranged and protected that they cannot be operated accidently. All material, other than that named above, and all labor necessary for the installation of line switches, fuses, con- duit work, wiring, connecting and test- ing is to be furnished by others. It should be remembered that all operator and especially electrically con- trolled operator needs occasional in- spection, lubrication, etc. The fore- sighted builder provides some means by which the motors and power stations can be reached without undue incon- venience. Where ordinary ladders are impractical a ‘“‘cat walk’’ or a movable platform is sometimes a real economy, and is especially useful as an aid to window washing. The picture at the right shows a ‘‘close-up”’ of electrical control power in the plant of the Na- tional Tube Co. at Lorain, Ohio. Operating Devices Fenestra Worm and Gear Operator Specifications Mechanical Operator to be of Fenestra Worm and Gear design, equipped with thrust bearings. Power line to be of 1’’ wrought iron pipe, held in place by adjustable steel brackets bolted to the mullions or structural steel work. Adjustable rolled steel arms are to be provided, one to each ventilator, solidly clamped to the power line. Chain or vertical pipe to be carried down within easy reach of the floor and provided with suitable means of operation. Operator to be erected by the manufacturer and left in complete working order. Fenestra Worm and Gear Operator is a torsion device, designed to operate from one power station single or mul- tiple rows of Horizontally Pivoted Ventilators. The power may be placed at the end of the run or at any intermediate point, but in no case may any ventilator be located more than 40’ from the power. Where one run of ventilators is to be operated, the maximum run on either side of the power is limited to 40’ and 6 standard two-pane high vents. Where two runs are to be operated from the same station, the maximum run on either side of the power is limited to 20’ and three standard two-pane high vents in each run. Where three runs are to be operated from the same station, the power should be placed at the end : -rtrtsi‘ésl#é‘CONCCN aA of the run, which is limited to 20’ and Strength and simplicity are the characteristics of the Fenestra 3 standard two-pane high vents in Worm and Gear Operator, designed for use with each run.

These supports are designed to pro- vide for the adjustment of the operator, toward or away from the sash as desired. To the horizontal pipe the venti- lator lever arms are attached. One armis used for each vent, this being attached to the cam bracket at the sill of the ven- tilator. The pipe is connect- ed toa gear, which is operated bya machined worm. Power is transmitted to the worm, either by means of a chain operating over a wheel, or by means of 1’ vertical pipe running down to a miter gear provided with a crank within easy reach of the floor. Materials Lever arms are of rolled steel and have an exclusive advantage in being adjustable to any length to clear any obstructions which would otherwise interfere with the action of the arm. Worm, gear and chain Power in Inclined or Inverted One of the advantages of the Fenes- tra Worm and Gear Operator is its easy operation when the power is in an inclined or an inverted position. Frequently cranes or other obstruc- tions interfere with free operation when the power is in normal position. When wheel are all cast with a special view to Ball thrust bearings are used to overcome friction. easy and free operation. Vertical and horizontal pipe are 1” wrought iron. Chain is made of small, double links, galvanized, and is un- usually easy to handle. The Fenestra adjustable pipe support is attached to the steel sash mullion or building construction and is so designed that it holds the torsion line in any desired position. Erection Fenestra Worm and Gear Operator is designed as an integral part of Fen- estra sash. In erection, before the operator is attached, all ventilators such a problem arises, it is perfectly feasible to tip the power to any desir- able angle, or turn it up-side-down. When this is done, the chain is carried over idlers to a convenient point of operation where it is brought down to the floor. 7/PPED iV PEVER SE POSITION. 50 must work freely and, in closing, weather at all points. The operating device cannot be expected to correct distortion of the sash that may occur by faulty erection. Sometimes Fenestra sash or operator, correctly manufactured, is ruined through faulty erection. The result is an installation alike unsatisfactory to the cus- tomer and to ourselves. To obviate such errors, we offer to builders the services of the Fenestra Construction Com- pany, a subsidiary of the Detroit Steel Products Com- pany, thereby concentrating authority and responsibility under one head and insuring the erection of Fenestra ma- terial in accordance with our recommendations. The Fenestra Construction Company is organized to handle the erection of oper- ator as well as sash, relieving the builder of all details. Branch offices are maintained in Detroit, New York, Phila- delphia, Boston, Chicago, Birmingham, and San Fran- cisco. These offices are es- pecially equipped to follow shipments, look after prompt delivery of material and see that it is properly installed. The Fenestra Construction Company guarantees a complete and _ satisfac- tory installation. Position The accompanying diagram shows details of powers both inclined and inverted. The cross section of the building shows a situation where in- clined powers are desirable. The ven- tilators, on the right side of this narrow monitor, could not be seen by a man operating them from a station along the right hand wall. It is therefore much better to tip the powers and bring the chains on idlers across the monitor and down the opposite wall. By this method the person operating the mechanism can always see just how far the windows have been opened or closed. At the extreme right in the diagram, is a cross section showing how an in- verted power allows the chain to descend close to the wall, thus escaping a traveling crane. Where the power is inverted, it is of course necessary to attach the lever arms to the top of the ventilators instead of to the bottom.

Its chief advantages lie in its easy operation and in the fact that the number of ven- tilators operated from one power is practically without limit. This is a tension device, consisting of a 1” horizontal pipe connected to a power similar to that described under “Fenestra Continuous Operator.’ Channel shaped tension arms, with one end clamped to the tension line, are attached at the other end to the head of the ventilators by means of a uni- versal joint. The ventilators are opened by pulling in at the top rather Ss This is the interior view of the monitor shown at the top of the page. Fenestra Continuous Operator. than the usual method of pushing out at the bottom. All arms are adjustable and, when properly attached, provide a 100% opening. The operation of the mechanism is exceptionally easy and rapid, due to the fact that the weight of the venti- lators is balanced and carried entirely by the sash and the building construc- tion. Erection Many excellent building specialties prove unsatisfactory when carelessly installed, or when erected by men un- familiar with the method intended by the manufacturer. To insure that the Fenestra operator will give the service required, we have organized, as a sub- sidiary, the Fenestra Construction Company, an organization of trained Fenestra service men, who are equipped to undertake the erection of Fenestra sash and operator under a separate contract, relieving the builder of all details and guaranteeing the proper and satisfactory completion of the job. The use of this service places the responsibility for a correct installation definitely with one concern and insures freedom from the difficulties and mis- understandings that sometimes arise where special material is handled by inexpert workmen. The power is the same as that shown under Arms connecting the head of the ventilators to the tension line pull the ventilators in at the top instead of pushing them out at the bottom. 53 Operating Devices STANDARD Rs STANVDARD 36” AR/7 , PART 893. ae ee TRAVEL OO ol npr AnnrlL_] CLAMP € SW/IVEL/| RACK HANGER; ROLLER BRACKET; PART 890, PART 927.

All jambs and mullion sections shall be of solid rolled steel I-beam type. Flaring channel guides shall be riveted to these sections to provide line contact weathering and guides for the sliding units. All sliding units shall be held by fittings which will permit easy adjustment. Chain shall be of gal- vanized flat links and run over roller bearing pulleys. All pulley housings shall be attached to the inside of the sash frame and easily accessible. All Counterbalanced Sash units shall be erected and all hardware attached, by the sash contractor. After erection and before glazing, all sash should receive a final coat of paint by the general con- tractor. All glazing shall be done under another contract. All pointing and grouting shall be done under another contract after the erection is completed. The pictures show exterior views of two popular types of Fenestra Standard Counterbalanced Windows. The use of the vertical muntin bars is largely a question of taste and the architectural effect that is desired. When closed, the sash are weathertight, and when opened, fifty per cent ventilation is obtained, heated air escaping through the top and fresh air en- tering through the bottom opening. 55 Counterbalanced Windows Advantages of Counterbalanced Windows Fenestra Counterbalanced Windows are finding increasing favor among architects and engineers for use in pub- lic buildings, offices, schools, loft build- ings and industrial structures of the better class, in which it is desired to employ a sliding steel window. For such buildings, Fenestra Counter- balanced Windows have particular ad- vantages, namely: 1—The ventilators slide up and down in the way everyone is ac- customed to operate a window. 2—They provide natural ventila- tion automatically, since the exit for heated air at the top is always equal to the inlet for fresh air at the bottom. The ventilating area is one-half of the entire window area. 3—They are easily washed and may be economically equipped with roller shades, screens and windshields. 4—They are fire resistant, being built of steel sections. 5—They are manufactured in standard sizes, which are more economical and can be shipped quicker than other sizes. Details of Construction Particular attention is given to the finish and workmanship on Fenestra Counterbalanced Sash. The design is attractive and the construction is of a character that harmonizes with build- | ings of the highest architectural finish. Where desired, brass weathering is supplied at slight additional cost. Sections To insure easy operation and satis- factory weathering, Fenestra has per- fected a flaring channel guide which is securely riveted to the I-beam jamb sections. (See Figs. 1, 2, and 3.) The equal leg channels forming the sides of the ventilators slide between this flaring channel guide and the flanges of the I-beam. Two continuous line contacts are thus secured, which provide efficient weathering. At the same time, the sliding sections move easily, since at no point does a flat surface slide against another flat surface. Unequal leg sections at the head and sill and interlocking sections at the meeting rail provide effective double contact at these points. Jambs and mullions are of solid rolled steel 4” I-beam section. Head and sill members are heavy pressed sections, especially designed. Sliding units are of especially designed solid rolled sec- tions and the corners are welded to insure rigidity. All sash are carefully gone over by hand, to insure a finished appearance. Brass Weathering Brass weathering sections of flaring channel design may be inserted at the jambs of both upper and lower sliding units at slight additional cost. These channels are riveted to the I-beam sec- tion in such a manner that they are entirely covered by the equal leg jamb sections of both sliding units. Thus, with this construction, both sections slide and weather with line contact against brass. (See page 57.) Fig. 5 56 Fittings The Pulley is of roller bearing type, adequately “‘housed,”’ but not requiring a box effect at the head or a deep shoulder in the concrete lintel. This housing also serves as a connection between the jambs and the head members, is accessible for oiling and easily removed if desired. Specially heavy gal- vanized chain, tested to a 400-pound load, connects the upper and lower vents. (See page 56, Fig. 1.) A nest having the contour of the links of the chain is cored into the chain catch. This nest receives three links of chain, which fit snugly, thus developing the full strength of the chain and eliminating the need for a pin, which is liable to fracture the link through which it is inserted. The chain catch on the lower vent is adjustable, so that slack, if any, can be readily taken up. (See page 56, Fig. 2.) A cam action locking device draws the meeting rails together tightly, thus adding to the effectiveness of the weathering. (See page 56, Fig. 4.) The handle or handles, if the sash is wide enough to require two, are of a neat, pleasing design and substantial construction. They are attached to the bottom rail of the lower sliding sec- tion by a bolt and lock nut, which makes it impossible for them to work loose, as is frequently the case when hardware is tapped on. (See page 56, Fig. 5.) When desired, pole operation may be used, as a hole is provided for this purpose at the head of the upper unit. The adjustable sill clip is slotted, so that the jamb section can be moved in either direction to facilitate the erection of the sash and insure sufficient clearance for easy operation. (See page 56, Fig. 3.) Types of Sash Standard types of Fenestra Counterbalanced Sash are made without horizontal muntins, each pane of glass running from head to sill of each sliding unit, no light being more than 24” wide or more than 72” high. (See table.) Where desired, sash may be designed, using a single pane to each ventilator. Where large lights are used, the glass is held in place with glazing angles. This is sometimes very desirable in structures of the office building type. Occasionally, too, we are asked to design the sliding sections with small glass lights, using horizontal muntins, so that the general appearance of the window will correspond with Fenes- tra Sidewall Sash used in other bays of the same elevation. Where variations from our standard design are desired, we strongly recommend that designers consult one of our repre- sentatives, Erection To give satisfactory service, Counterbalanced Sash must be installed with considerable care and set absolutely plumb and true. For this reason, all Fenestra sash of this type are installed by our own erection organization, the Fenestra Construction Company. This company maintains offices in Boston, New York, Detroit, Philadelphia, Chicago, San Fran- cisco and Birmingham, and from these points covers prac- tically the entire United States. All sash of this type are shipped ‘‘knocked down,” the head, sill and jamb sections being assembled in the field, while the sliding sections are shipped assembled and ready for erection. 57 Counterbalanced Windows SASH D/I/TENS/ON WOOD MARBLE OR SLATE SILL | VERTICAL SECTION THRU COUNTERBALANCED SAS/, Counterbalanced Windows Symmetrical Standard Heights and Widths 2 PANES H/GH. 36'GLASS 65g" 42° GLASS 4B°GLASS 4° GLASS 60° GLASS 66 GLASS 72 GLASS pa SASH DIATE N S/O.

There are some conditions, however, under which the use of a solid steel Architects, Mundie & Jensen window carrying the label of the Under- writers’ Laboratories, Inc., is desirable or is required. Just what these conditions are can best be determined by consultation between the owner and his architect or contractor, and by careful reading of the Underwriters’ specifications shown on page 64. In appearance, location of ventilators and method of installation, Fenestra Underwriters’ Windows are identical with standard units of Fenestra Solid Steel Windows. Their use permits the builder to secure the same big daylight openings in exposures which require a labeled sash that he can obtain through the ‘tS The Clemetson Company, Chicago, III. use of standard Fenestra units in the other elevations of his building. Any number of units can be com- bined by means of the standard Fen- estra Solid Rolled Steel T-bar Mullion, to fill any width of opening. Single units can be built to any standard size up to 7 feet by 12 feet, either dimension being taken for height or width. However, the practical limit of ventilated sash is about 60 square feet, and of fixed light sash, about 75 square feet. While ventilators may be built up to an area of 3000 square inches, the practical limitation for Horizontally Pivoted ventilators is about 2,300 square inches and for Reversible ven- tilators, 1,344 square inches.

This label is attached by a representative of the Underwriters’ Laboratories, Inc. after the sash has been inspected. Any number of pivoted units may be combined in one opening by use of the standard Fenestra T-bar mullion. Any number of counterbalanced windows may be combined in one opening by use of the standard Fenestra I-beam jam and mullion section. ’ The tremendous heat of this fire caused the sash and mullions to bow toward the blaze; but though the walls and sills spalled and fell away, the glass and sash prevented the spread of the flames. 64 Underwriters’ Laboratory Specifications Types and Sizes All sash units shall be limited to seven feet (7’-0’) by twelve feet (12’-0’’), either dimension being taken as the height or width. Multiples of sizes within the required dimensions may be used to fill any openings by the introduction of the T-bar mullion. Ventilators Ventilators may be placed at the head, sill or jambs of the sash. Two ventilators may be placed adjacent in one sash unit, one above the other. Ventilators may be of the ‘‘Coun- terbalanced Type,’ ‘Reversible to Open Out Type” or ‘Horizontally Pivoted Type,” the latter pivoted 2” above center or 4” from the top to open out. Reversible and Horizontally Pivoted Types must be equipped with locking wings. All ventilators, except where counter- balanced, must be operated separately. Reversible ventilators must be equipped with the standard Fenestra iron cam handle, and those out of reach from the floor must have the standard Fenestra iron pole ring. Bronze hard- ware is not permitted by the under- writers. Ventilators pivoted 2’ above center must have the standard Fenestra cam handle and chain or standard Fenestra cam handle and stay bar. Ventilators pivoted 4” from the top must have the standard Fenestra cam handle and stay bar only. Counterbalanced ventilators must be equipped with standard Fenestra counterbalanced hardware. All ventilators are limited to an area of 3,000 square inches. Glazing One-quarter-inch (14’’) wire glass must be used to fill all openings. All glass is limited to fourteen inches (14’’) in width and forty-eight inches (48’’) in height. The exposed area of the glass shall in no case exceed 350 square inches and must be held in place by ze by 5% glazing angles. Inspection All Fenestra Underwriters’ Sash shall be inspected under the supervision of the Underwriters’ Laboratories, Inc., before shipment, and the manufacturers’ authorized Underwriters’ label shall be riveted to each sash unit. Painting All sash shall receive one dip coat of red mineral paint before shipment. Reversible Ventilator Windows nestr Reversible Ventilator Windows Fenestra Reversible Ventilator Windows are adaptable where the characteristics of steel windows harmonize with the architecture of the building—and where the builder desires an attractive, serviceable window at less price than must be paid for hand-made casements or special windows of unusual design. Because of their slender sections Fenestra Reversible Windows provide about 30% more light than wood windows of the same size, or, the size of the window may be reduced so that the same amount of light is secured as in wood windows, thus giving additional wall area. For this reason Fenestra windows are particularly desirable for offices and other structures where wall areas are at a premium, and also for schools where uni-lateral lighting is frequently desired and where the ratio of light area to floor area is fixed by law. It should be remembered that Fenestra is manu- factured from slender, durable sections of solid rolled steel. Such sections cannot be made to imitate the heavy lines usually found in wood windows and orna- mental or structural mullions. They can be installed however, in ornamental vertical and horizontal mullions when such architectural effect is desired. In such cases we do not furnish the mullions.

Reversible Ventilator Windows Details. of \@omstmuction The Framing Member The standard framing member used around type ‘A’ Fenestra Reversible Ventilator Windows is a specially rolled steel channel shaped section with unequal legs (shown on /IVLLION COVER at Age i 4G OPEM/NG DIMENSION page 75) known as the 792 Section. It is designed to add strength to the frame, afford a wide outstanding wing for anchorage in the masonry and provide a flat surface for a neat plaster finish. Dimension Points In Fenestra Reversible Ventilator Windows of the ‘“‘A”’ type, ‘Sash Dimension” does not equal ‘Clear Opening.’ Due to the construc- tion of the 792 Section, the sash dimension points on this section are taken 14” inside the Clear Opening on every side (see pages 75 and 76). In other words, where 792 Section is used, ‘Sash Dimension plus 1’” equals Clear Opening.” For the same reason 3’’ must be allowed for each mullion when figuring multi- ple openings. The Ventilator The ventilator is balanced with a nice pre- cision and opens or closes with unusual ease. The swinging end may be projected several inches without any appreciable movement at the sliding end. Thus, “Swing Out" Ventila- tors, opened slightly in stormy weather, afford all the protection of top hung windows, while ‘Swing In” Ventilators, similarly opened, have all the advantages of wind guards at the sill. Two point weathering is provided at every point where the ventilator meets the frame while extra long down-standing legs afford effective drip at head and sill. By tilting the ventilator beyond the hori- zontal, both sides of the window may be washed from inside the room. Arms and Brackets The ventilator is supported and balanced on two arms of tough spring steel. These arms are attached to the ventilator by bronze shoulder bolts equipped with bronze washers. Connection between the arms and the framing members of the ventilator is 68 made by means of specially designed mal- leable brackets. When the ventilator is of the Swing In type, the malleable brackets act as alignment stops. The 190 Section All Fenestra Reversible Ventilators, in both Type ‘“‘A”’ and “B" windows are made with a specially designed jamb section (No. 190, shown below). This provides extra large clearances between ventilator and sash, thus assuring easy operation without decreasing the weathering. It also prevents possibility of fouling the masonry when the ventilator comes to the jamb. Phantom view of Bronze Fric- tion Shoe Bronze Friction Shoes Each Reversible Ventilator is equipped with two bronze friction shoes, one on either side. These are attached to the top rail of “Swing Out’ windows and to the bottom rail of “Swing In’’ windows and slide verti- cally in the frame members at the ventilator jambs. They guide the ventilator, insure its easy operation, prevent rattle and assist in holding the window open at the desired angle. They consist of bronze channel shaped shoes, mounted on shouldered studs, also of bronze. Fig, 3 Around each stud is an electro-galvanized compression spring covered by a _ weather- protecting bronze tube. The shoe complete is attached by a steel bracket, solidly riveted in place, its location accurately gauged to the fraction of an inch, thus assuring equal con- stant and proper pressure at the jambs. Welded Corners Ventilators are pivot ended and afterward electrically welded at the corners and ground down to a smooth and finished surface. Sash corners are also pivot ended and welded. Alignment Control To assist in the uniform alignment of all “Swing Out” Ventilators, when open, the Fenestra Alignment Control is provided. It consists of a spring bronze device, riveted inside each guide channel, and so shaped as to check the downward travel of the friction shoe (Fig. 1). The normal opening of every ventilator is, therefore, controlled at an angle of about 60 degrees. When it is desired to open the ventilator farther, slight pressure on the spring releases the stop (Fig. 2), and permits the friction shoe to slide past (Fig. 3). As the ventilator returns to its closed posi- tion, the spring action is automatic. Combined Units Two or more standard windows may be combined in the same opening by using the standard Fenestra T Bar Mullion. Add the sash dimensions of the various units desired; and to this sum add 3” for every mullion. See page 72. Mullion Covers Vertical Mullion Covers of pressed steel, as shown in the photograph, provide a neat and attractive means of covering the mullion recess where two or more windows are used in the same opening. Attachment is made by means of pressed metal clips, which are bolted to the mullion by the standard Fenestra mullion bolts located at the center of each glass light. To these clips the mullion covers are attached by bolts provided with acorn nuts. Where structural steel horizontal mullions are used, Horizontal Mullion Covers may be employed as shown, to house the steel work between the upper and lower windows. No other designs of vertical or horizontal mullion covers are furnished by Detroit Steel Products Co. The usual bolts used with our 101 Clips to hold the lower window in place are replaced by longer bolts, which extend through the mullion cover and are fitted with acorn nuts. 69 Reversible Ventilator Windows Jame and sill members of eversible Window showing electrically welded corner.

This is a carefully finished fitting of new and pleasing design, and is attached to the specially designed Z bar bracket, which, in turn, is solidly riveted to the sill bar of the ventilator. When the window is closed the cam handle lies in a horizontal position along the sill. A bronze strike plate is riveted to the sash at the sill of the ventilator and this carries a 6’’ bronze stay (Part 122). When the window is open farther than 6’’, no stay is used, as the balanced construction holds the ventilator in position. For Swing Out Ventilators beyond reach from the floor, pole operation is usually desired. A bronze pole ring (Part 151) is attached at the head of the ventilator, while at the sill the standard bronze cam handle and the bronze strike plate without the stay are provided. The pole is used to lift the cam handle and tilt the ventilator slightly, after which a gentle pull on the ring opens the ventilator as desired. For Swing In Ventilators within reach from the floor an automatic latch with bronze handle is supplied at the head (Part 112). A slight pull on the handle releases the catch Part 151 Part 147 70 Part 114 Part 112 and allows the ventilator to open inward. In closing, the latch works automatically. The specially designed bronze spring catch (Part 146) with endless chain is used at the head of Open In Ventilators, which are beyond reach from the floor. These ventila- tors are not standard however. Part 147 is a spring catch and keeper used in Swing In Ventilators within easy reach of the floor. Glazing The standard method of glazing Fenestra Reversible Ventilator Type “A” windows is with 14” glass, bed puttied, and held in place by glazing angles. These angles, mitered at the corners, are supplied as standard to- gether with brass screws of “barrel” design. Underwriters’ Windows Reversible Ventilator Windows with “Open Out” Ventilators may carry the Underwriters’ label, subject to the following conditions: No glass light must exceed 350 sq. in in area. No individual unit must exceed 7’ x 12’, either dimension being taken as width or height. Special glazing angles and hardware are required. If Underwriters’ Windows are required they must be specified at the time the job is estimated. Reversible Ventilator Windows of the “Open In” type cannot be labeled by the Underwriters. Part 146 Reversible Ventilator Windows Standard Types and Sizes Standard Fenestra Type ‘“‘A’ Reversible Ventilator Windows are determined by certain standard ventilator dimensions. The accompanying diagrams show the points from which these di- mensions are taken. As in all steel windows, the ventilator lights which abut on the head, jambs or sill of the ventilator are trimmed 1” along the abutting edge. The standard widths and heights for both Open In and Open Out Ventilators are: Widths 28”’ Wide Vent (Open In or Open Out) takes 26’ wide glass 36’ Wide Vent (Open In or Open Out) takes 34’’ wide glass Heights 12” High Vent (Open In) takes 10” high glass, cut full 16” High Vent (Open In) takes 14” high glass, cut full 24”" High Vent (Open Out) takes 22” high glass, cut full 32” High Vent (Open Out) takes 30” high glass, cut full Around these ventilator dimensions is built the entire stand- ardization of all Reversible Ventilator Windows. Fixed lights are always used at the head of each unit to facili- tate shading and permit easy operation of the ventilator.

Reversible Ventilator Windows Installation Details Type ‘A’ How to Use the Table of Symmetrical Combinations The table of Symmetrical Combinations on Page 72 shows Fenestra Reversible Ventilator windows used in multiple openings, that is, two, three or four individual units used with mullions between to fill a single opening. The column at the left shows height and width dimensions, the width dimensions including 3” for each mullion. Note particularly that these figures indicate Sash Dimensions to which one inch must be added to secure the dimensions of the clear opening. See Page 68 under “Dimension Points.”’ Having selected the height and width dimensions and from these obtained the dimensions of the clear openings, you will want to know how many units are required per opening. This information is contained in the next column to the right, while the third column indicates the total number of lights. In the extreme right hand column are given the number and size of each light in each unit. For example, suppose you want to fill an opening approximately 7’ high by 10’ wide. Under Height Dimensions you will find 6’ 1034” to which 1” must be added, giving a standard height of 6’ 1134”. Under widths you will find 9’ 984” to which 1” must be added making a standard width of 9’ 1034”. By making your openings according to these dimensions you can use three standard units and two standard mullions. Each unit will be four panes high, and one pane wide. Erection of Fenestra Reversible Ventilator Windows All Fenestra Reversible Ventilator Windows, Type “‘A’’, shown on page 72 must be installed by our own erection department, the Fenestra Construction Company. This insures a con- centration of responsibility, relieves the owner and general contractor of much detail and guarantees windows will operate satisfactorily. To leave the installation of Reversible Windows to the general contractor is no 73 more logical than to expect him to install an elevator. It is of the utmost importance that Re- versible Windows be set in prepared openings; that they be erected true and plumb; that clearances be carefully observed and that the framing members are not jambed or crowded. After installation, the windows should be carefully grouted by the mason contractor. It is very essential that all ventilators be adjusted before glazing and that after glazing, the ventilators be locked tight until the putty is set. Sill Anchor Clips, Part 435-S Particular attention should be called to the desirability of using Sill Anchor Clips, (Part 435-S) as shown below under certain conditions in almost any type of sill construction. This anchor serves to hold the sill solidly in the masonry and is of particular value where the sash is extremely wide or where a ventilator comes directly at the sill. Our recommendations are that sill anchors be used; First,—in all cases where ventilators come to the sill of the sash, regardless of width of the sash. (Holes are already punched in the sill sections to accommodate these anchors. ) Second,—in all cases where the sash is over 5’ 0” wide, regardless of the location of the ventilators. Third,—in all multiple unit openings where the mullions are not anchored at the sill. All Part 435-S clips are supplied without extra charge. Ses WOOD, MARBLE OR SLATE STOOL OPENING D//7.

The minimum distance required is 314”. We furnish at slight additional cost stand- ard shade bracket clips which may be easily attached by drilling and tapping two holes in the inside leg of the jamb section. These clips as shown at the right are slotted to accommodate any standard shade bracket, these brackets being purchased locally. This detail is shown very clearly on page 79. Where a kalamein moulding is used as a plaster finish around the windows, it is very easy to attach any standard shade bracket direct to the moulding, as shown in the draw- ings at the bottom ofthepage. Cross sections of this moulding are shown on page 79. Methods of Screening We do not make nor furnish screens for Fenestra windows, but we will be glad to refer those who are interested to competent man- ufacturers who make the screening of steel windows a specialty. On page 79 are shown some suggestions for Suggestion for attachment of shade brackets when kalamein or other finish moulding is used as trim inside Fenestra windows 78 Standard Fenestra shade bracket clips (supplied as an extra) showing slot to accommodate any standard bracket. Shade bracket clips cannot be used when Open In Vents come to the head of the sash screening the various types of Reversible Ventilator Windows. Several methods of screening are shown, including “roll up” screens, vertically and horizontally sliding screens, pivoted screens for Open In and Open Out Ventilators. The application of these suggestions naturally depends upon the type of building and the design of windows used. Note particularly that when screening is done on the inside, the screens must be kept back at least 314” from the inside face of the window in order to clear the hardware. This applies also to shades, but where screens and shades are both attached, the shade naturally must be kept inside the screen. This dimen- sion may be reduced in some cases. Finish at the Mullions While we furnish as an extra, a pressed steel mullion cover as shown on pages 69 and 77, two other suggestions are shown on page 77. One shows a kalamein mullion cover, suitable for use with kalamein moulding at the jambs. The other shows a neat finish secured by the use of metal lath and plaster. Standard Fenestra mullion covers are, however, the only ones furnished by Detroit Steel Products Co.

Glass sizes cares) Yo (12 x18"), and” Z (14” x 20”) to harmonize with the glass sizes of standard pivoted units. The only essential difference between this type and standard Horizontally Pivoted windows lies in the movement of the ventilator which slides down from the top while swinging out from the bottom, instead of being pivoted near the center. Details of Construction The Framing Member The framing member on all Type “B” Reversible Ventilator Windows is our standard 94 section of solid steel as shown in the detail below. The outstanding leg anchors in the masonry at head jambs and sill approximately one-half inch. The sash dimensions of these units are always the same as the dimensions of the clear masonry opening. In other words the dimension points are taken exactly as in Horizontally Pivoted sash. Where two or more units are used in the same opening, the standard Fenestra T-bar mullion is used between units, 2” being allowed for the width of each mullion. The Ventilator All standard Type “B” ventilators are of “swing out’ design, and are balanced on side arms of tough spring steel. Arms, brackets and bolts are exactly the same as those used in the manufacture of Type “A” Reversible Ventilator Windows. Vent corners are pivot ended and electrically welded. The ventilator meets the sash with a two-point flat contact all around the opening thus insuring storm- tight weathering. Long down-standing legs at head and sill form drips which provide additional protection at these points. Both the inside and the outside of the win- dow may be washed from the inside, by merely tilting the ventilator beyond the horizontal.

Double-strength glass may be used with glazing clips Extra Clearance at Jambs An extra clearance at the jambs is provided by the use of our 190 Section as in Type “A” windows. This precludes the possibility of the ventilator fouling the masonry and insures free and easy operation without decreasing the weathering. Bronze Friction Shoes Bronze friction shoes, as used in Type “A” windows are attached to the top bar at the jambs of all ventilators. These not only prevent rattle, but assist in holding the ventilator open at the desired angle. In addition, they act as ventilator guides and increase the ease of operation. Alignment Control Ventilators are easily held open at a uniform angle. This is accomplished by a spring bronze device riveted inside each guide chan- nel. This stop checks the downward travel of the friction shoe and controls the opening at an angle of 60 degrees. A slight pressure on the spring releases the ventilator and permits it to open farther. As it returns to a closed position the spring action is automatic. Mullion Covers Standard Fenestra vertical mullion covers may be used with all standard Type “B” windows but due to the construction of the framing member, horizontal mullion covers are not applicable.

Ventilator lights which abut on the head jambs or sill of the ventilator must be trimmed 1” along the abutting edge. Semi-Standard Types Although the standard units of Fenestra Type “B” Reversible Windows have all ventilators opening out, it is possible to secure as Semi-Standard, any of the types shown, with the lower ventilator made one pane high and opening in. Where a one-pane-high Opening In Ventilator is desired, it is usually better to locate it at the sill, although if the sill height is exceptionally low, it may be placed one pane up. Either of two types of opening in ventilators may be used. The standard Reversible type is constructed exactly like those described on page 68. If desired, however, the ventilator may be pivoted 34” from the bottom to open in from the top. Part 146 1 Part 147 When this is specified, the friction shoes are omitted and the ventilator opening is limited by concealed side arms. Shading The best method of shading Type ““B” Fenestra Reversible Ventilator Windows is by attaching the shade brackets directly to the building construction. (See drawings at bottom of page 78.) Due to the construction of the 94 Section, it is not easy to utilize the standard Fenestra shade bracket clip shown on page 78. Screening The suggestions for screening that are shown on pages 77 and 79 apply equally well to the types of Reversible Ventilator Windows on page 82. We do not make nor supply screens but are glad to refer those who are interested to companies who make the screen- ing of steel windows a specialty. Erection All Fenestra Reversible Ventilator Windows of the type shown on page 82, must be installed by the Fenestra Construction Com- pany, which is a subsidiary of the Detroit Steel Products Company. The men employed by this organization are all expert steel sash erectors and are equipped to install our Reversible Ventilator Windows Part 151 Part 150 products with much greater speed and accu- racy than any general contractor, no matter how conversant he may be with this type of window construction. Standard Iron Hardware Iron Hardware is supplied as standard on all standard Type “B” Fenestra Reversible Ventilator Windows. For Swing Out Ventilators within reach of the floor, the cam handle, Part 150, is sup- plied attached to the Z bar bracket, which is riveted to the sill of the ventilator. Swing Out Ventilators out of reach from the floor are provided with cam handle at the sill, and pole ring (Part 151) at the head. For Swing In Ventilators, within easy reach, a spring catch and keeper are provided at the head. of the.wventilators .(Part 147.) 2 Phe catch has a short handle in which is a finger- sized hole for ease of operation. A slight pull releases the catch and allows the ventilator to open inward. A specially designed spring catch with end- less chain, (Part 146) is used with Swing In Ventilators out of reach from the floor. These windows are not standard however. Where desired, bronze cam handle and bronze pole ring may be secured for Type “B” ventilators at slight additional cost.

This helps the archi- tect maintain his ratio of window area to floor area and still pre- serve sufficient masonry for architectural effects. 3—The fireproof qualities of steel are an unquestioned ad- vantage. 4—Ventilation is more easily secured and controlled by Fen- estra windows which do not warp nor stick—always operate se Se Architects, Perkins, Fellows & Hamilton Contractors, The H.

The Jackson Building, Asheville, North Carolina, will be the first fireproof office building in the western part of the state. It is to be 14 stories high, 204 feet. Mr. L. B. Jackson writes: “We are glad to state that we purchased Fenestra Reversible Windows for this building after due con- sideration and a thorough investigation of all the differ- ent types of windows that are now on the market. We believe that the type of windows selected by us gives our tenants better control of ventilation. Another reason we selected Fenestra is because of the fact that the bottom ventilator is hinged to act as a wind shield, this being a very important feature in office buildings. “We appreciate the co-operation that your repre- sentative has given us and feel sure the windows will prove satisfactory in every way.” 89 Reversible Ventilator Windows (uae Architects on both buildings, Aleck E. Curlett and Claud Beelman Large Picture—Sun Realty Company Building, Los Angeles Small Picture—Fifth Street Store, Los Angeles 90 For Hotels The ruffled curtains and small glass lights add a very “homey’’ atmosphere to the otherwise typical hotel bed- room of the Hotel Rennas, Shamokin, Pa. Fenestra Reversible Ventilators projecting entirely outside the room make possible this very attractive treatment of the window opening. One gets an impression of lightness and airiness even with the upper venti- lator closed, due largely to the elimina- tion of wood trim while the plaster finish is carried directly to the window frame. By reversing the ventilators the window washer cleans both sides of the glass from the inside. For Banks The window treatment employed in the Peoples State Bank, Astoria, IIl., is typical of present day bank construc- tion. The building is of classical colonial design, the long slender mun- tins of the windows enhancing the appearance of height while the cam- bered heads add to the monumental dignity of the building. The height of the windows assures an abundance of daylight in the banking rooms. The sash is reversible and since the ven- tilators project outward, there is no obstruction to interfere with shading. Natural ventilation is secured by open- ing the lower ventilators to admit fresh air, while vitiated air escapes through the opened upper ventilator. Architect, Paul V.

People like to buy in an atmosphere of sunshine and fresh air Nestr Camber and Semicircular Windows Windows of Unusual Design Camber Head and Circular Head Windows Modern industrial builders tend to- ward the use of square headed window openings, rather than the camber and semicircle heads so popular some years ago. On the other hand, the attractive appearance of the arched head is self- evident, and in brick buildings it some- times saves the cost of steel lintels. Where economy is an important item, it is not unusual to fill segment head openings with Fenestra 12-gauge steel filler plates bolted to the head of standard square head Fenestra sash. Architects, Bakewell & Browne Standard Fenestra Types Where cambered or semicircular sash are desired, they may be secured in any of the standard Fenestra designs and dimensions shown on the following pages. In designating camber heads, the letter C is used preceding the glass size Y or Z, and the figure following the glass size gives the number of lights In designating semicircular heads, the letter S is used before the glass size Y or Z, and the figure follow- ing the glass size indicates the number of lights wide. Where a semicircular head is used Contractors, P. J. Walker Company Leland Stanford Junior University, Palo Alto, California In the library of this beautiful university, Fenestra semicircular windows are effectively used to harmonize with the archi- tectural design. The ventilators at the top and bottom of the windows are controlled by Fenestra Worm and Gear operators. 93 The inset shows the exterior of the principal facade of the library. Camber and Semicircular Windows Designed and erected by City Engineers Auxiliary Power House, City Light Plant, Seattle, Wash. Each bay in this power house is 30 feet high and 10 feet wide, composed of nine standard units. The built-on camber head makes the upper units of each bay a special type. with horizontal structural mullions above several combined square head sash, the number of lights in the width of each unit is also designated. Thus an “S Z 10-343’ indicates a semicir- cular head, with 14’ x 20” glass, 10 lights wide, used above three units of square head sash, these units being respectively 3 lights, 4 lights and 3 lights in width. Note particularly the four dimen- sions shown under each of the standard types of camber heads on the opposite page. ‘“S D” means ‘Sash Dimen- sion;” ‘“‘H”’ means ‘‘Height from sill to center of arch;’ ‘‘A’”’ means “Arch,” or the distance from the sides of the arch to the sill; and ‘‘R’’ means “Radius” of the camber. These dimen- sions must always accompany orders for camber heads. In semicircular heads the ‘‘H” and “R’”’ dimensions are naturally identical, while the ‘‘A”’ dimension is eliminated. Details of Construction All separate camber and semicircular heads up to and including 7’ 314” wide (six lights of Z glass) are built with our No. 70 section at the sill, so that they may be bolted directly to the head of a square head unit below. (See Fig. 1 at bottom of page.) As this No. 70 section cannot be used over vertical mullions running to the head of the Maurice C. Couchot, Engineer heads have been standardized in the widths and heights shown on the op- posite page. In no case should any separate camber or semicircular head be designed for a width greater than 7’ 34%” unless a structural horizontal mullion is used below. Where it is desirable to use separate semicircular heads of a greater width than 7’ 31%”’, the curved head is built with our No. 94 section at the sill, so that it may be attached to the struc- tural horizontal mullion. (See Fig. 2 Municipal Electric Light Plant, Alameda, California Semicircular units of Fenestra were used to harmonize with the Spanish type of architecture, in which the round arch is the predominating characteristic. at bottom of page.) These heads may be designed more than 7’ 314” wide and more than six lights wide, provided the standard designs and dimensions shown on the opposite page are fol- lowed. “Built on’? camber or semicircular heads—that is, curved heads built on as an integral part of the sash—are special in design. We strongly recom- mend that builders consult the nearest Fenestra representative before ordering these special types. square head sash, openings containing two or more square head units must be equipped with a structural horizon- tal mullion or else the curved heads must be built on as an integral part of the sash.

These sash are usually made with glass lights 6” x 9’”’ and with ventilators one light high, pivoted in the center. Detention Sash has also been used in connection with wooden frames in asylums and hospitals. In the Oregon State Asylum, Portland, Oregon, the upper portion of the window opening is equipped with a stationary wooden frame, in which a Fenestra fixed light sash, glazed from the outside, is set. The lower portion of the opening con- tains a movable wooden sash, glazed on the outside, and outside of this a stationary Fenestra unit, unglazed, the latter acting as a guard when the wooden sash is opened. Among the other installations of Fenestra Detention Sash are Northern Insane Hospital, Norlum, Washington; Granite City Penitentiary, Illinois; Wingdale Prison, New York City; Northern Michigan Asylum, Traverse City, Michigan; Waupun Prison, Wau- pun, Wisconsin; Michigan Home for the Feeble Minded, Lapeer, Michigan, and Coquitlam Asylum, Vancouver, BaGaCanadas will escape the bars on the outside.

One large glass light is used in the ventilator, held in place with glazing angles, while above, below and at either side of the ventilator the glass is just twice the standard size. Dimensions and installation details are incidental with those of standard sidewall sash, but the large glass lights harmonize with an ornamental treat- ment around the window openings where the architectural appearance of the structure demands artistic handling.

Compare the glass area in this wood window with the glass area in this Fenestra Window Advantages to Home Owners and Builders To Home Owners They admit, on an average, 80% more light than wood windows of exactly the same size. They are made from solid rolled steel sections that never warp nor stick—always open and close easily. When open, they admit more air—thus providing better ventilation. They provide better protection against weather because they shut tight with a two-point flat contact—never rattle. Being made of solid rolled open hearth steel, they are non-inflammable and fire-resisting. They last longer and look better than wood windows— never split, splinter, nor decay. They are very easy to screen, screw holes being provided for that purpose. Being of steel, they discourage prowlers and form a pro- tection against rodents which sometimes gnaw through wood windows. 1 10. To Builders They come assembled—sash, frame and hardware all ready to install. Jambs and sill are in one continuous piece making the frame absolutely rigid. By removing two cotter pins, the sash may be taken out of the frame, and their accurate manufacture makes them interchangeable. They are less bulky than wood windows, and, therefore, much easier to handle. They are adaptable to any type of construction—as easy to set in poured concrete or concrete block as in brick. The mason does the entire work of installation—wood windows require the work of a mason, a carpenter anda painter. They save time—an experienced mason can install a steel window quicker than a wooden one. They are already painted—one priming coat—before they are shipped from the factory. They are for sale by local dealers who carry them in stock for immediate delivery. With all their advantages, their cost is surprisingly low. Basement Windows Basement Windows Sold Exclusively Through Dealer In localities where dealers have been appointed, Fenestra Basement Windows are sold exclusively through them. Hundreds of dealers in all parts of the country carry these windows in stock ready for immediate delivery. Any responsible dealer can secure these windows by writing to Detroit Steel Products Company, 2250 East Grand Boulevard, Detroit. In localities where no dealers have been appointed and where the builder or home owner wishes to deal with us direct, we shall be glad to quote prices. Details of Construction Hinges are large, easily accessible and have re- movable hinge pins. Sash can be glazed and installed after frames are in place. Self-centering wedge lock which insures that win- dow will close and seat properly and be free from rattles. Absolute anchorage and air- and water-tight weathering at the jambs are obtained by means of the fin which projects into the masonry. The flare in front of the fin provides a guide for the brick layer, and gives a neat finish similar to a brick mould. The leg at the back of the fin serves as a line guide to the mason in laying up the inside of the wall, and prevents the sash from being fouled. Weather Tight Head Connection The upstanding leg of the casement head section projects up back of the lintel assuring weatherproof anchorage in the building. Please note also the two point flat contact between sash and frame. The Drip Keeps Water Out At the sill, where special protection from driving rain is required, the front leg of the channel forming the sill of the sash is turned out and down, forming a drip, which keeps the water out. This feature, in addition to the double con- tact weathering between sash and frame, and the imbedded leg of the frame member makes the sill weather- proof. A Three Purpose Locking Device To draw the weathering members on sash and frame tightly together; to provide a simple and effective means of securing the sash when closed, and to furnish a convenient method of holding it open,—this is the triple /THIS LEG AssuRes TIGHT ANCHORAGE AND PROTECION AGAINST WEATHER BAFFLE Qutside SERVES” AS A GUIDE FOR rHeies Keer” “IN PLACE 100 80% More Light purpose of the self centering lock used on Fenestra base- ment windows. The lock itself is a heavy wedge, attached to a sturdy ring on a strong chain, riveted to the sill member of the sash. A tapered and slotted tongue is attached to the sill member of the frame. The sill member of the sash is notched to ride over this tongue so that as the sash closes, it is automatically brought to center. The wedge slips into the slot, bringing the weathering tightly into contact and locking the window. This self centering feature is important since it insures that the sash will seat accurately. The sash is hung on butts, which are accurately located and stoutly riveted to the sash and frame. The split hinge pins can be slipped out, and the sash removed for glazing, either before or after the windows have been delivered to the job.

For houses with low grade lines, we recommend this size, which provides 150% more daylight than a wooden window to fill the same sized masonry opening. This three light window, taking 12 by 18 inch glass is very popular. It works out well with either brick or con- crete block and is the one most used in the average type of construction. This size works out par- ticularly well with the 24 inch concrete block in use in some sections of the country. The sash is equal to one and a half blocks in width and to four blocks in height, with a sill. | HOVE OVERALL | How To Install Fenestra Basement Windows Pa Finished installation in poured concrete 101 ae a S Finished installation in concrete block In Brick The channel and fin construction of the Fenestra jamb member provides a guide for the mason in laying up both the inside and the outside courses of brick, the outstanding fin providing secure anchorage. With the brick work true and plumb behind these guides there is no chance of binding the sash and preventing it from opening. The sill may be of cast stone, cut stone, poured concrete, brick, or other material, set so that the down- standing leg of the frame is behind it. The sill may then be finished on the inside with any of the common methods.

Block machine manufacturers are now providing end gates for casting slotted end blocks similar to the detail shown above. Many block mak- ers are carrying these blocks in stock. The slot is filled with mortar before the block is set in position. Where slotted end blocks are not obtainable, blocks with concave ends are em- ployed, the outstanding fin at the jamb of the sash extending well into the cavity which is grouted flush. Be sure to wet the block before grouting. Any type of sill construction may be employed. In Poured Concrete When the basement is to be of poured concrete, it is customary to provide a prepared opening to re- ceive the sash, similar to that shown in the detail above. This rebate is made by nailing a strip to the inside of the form at the jamb. When the form is removed, the sash is slid into the rebate thus left, and grouted in, with the flaring edge tight against the front of the rebate. Sometimes, the form is built against the fin, with proper allowances not to foul the sash. The wall is then poured with the window in place. Usual methods of sill construction are employed.

Masonry sills are usually used, al- though wood can be used as shown. In Tile and Field Stone Anchor clips 8” long are supplied without extra charge—four for each window. These imbed in the masonry at the jambs and project on either side of the fin, as shown in the drawing below. Construction In some sections of the country, the base- ment wallis brought to ground level and the wood construction starts immediately above the grade line. When such is the case, the Fenestra 102 General Utility Window A New Steel Window for Small Buildings The new Fenestra Utility Window is specially designed for small buildings such as private garages, filling stations, shops, stores, and basements high above the grade; also for barns, gran- aries, implement sheds, poultry and hog houses. It embodies all the advantages of steel window construction, more light and ventilation, greater ease of operation, protec- tion against fire, and security against intrusion, and in addi- tion, offers surprising economy and ease of installation. The window is made from standard Fenestra solid rolled steel bars. It comes in only one size—3’414" wide by 3/714” high with 1%” extra outside these dimensions for anchorage in the building. The sash, or ventilator, is 22” high pivoted 2” above center and provided with a stay bar which permits 20, 40 or 60 Fenestra Utility Window in concrete block.

When the sash is closed the cam locking device falls into place securing the window auto- matically while the weathering makes a two-point flat contact all around. All windows are given one dip coat of red mineral paint before shipment but should be painted a second coat after installation. Distribution is made exclu- sively through dealers whose stocks are supplied from a score of convenient warehouses. You will find this window attractive, easy working and moderately priced. Construction Details Details of the Fenestra Utility Window and methods of installing are shown at the right. The column at the left shows installation in concrete block, the upper sketch showing the window with a poured concrete lintel and sill. Note that it fits exactly in a space 244 blocks wide by 6 blocks high (this dimension including the sill). The head detail shows the necessary rebate left in the lintel into which the projecting leg of the window frame is inserted and grouted. This rebate is usually made by nailing a wood strip inside the form before the lintel is poured. The sill detail shows the window as it would look set on either a poured concrete sill or a precast sill. The jamb detail at the bottom, shows an installa- tion in a slotted end concrete block. These are now furnished by most block makers for steel windows. The common block with concave end may be satisfactorily used. The column at the right shows the window installed in wood. Here the opening should be made a little larger than the overall dimensions of the window. The head detail shows the projecting leg set against a wood strip with the casing brought down on the outside to hold it in place. The sill detail shows the use of wood screws to hold the window, countersunk holes in the frame being provided for that purpose. At the jamb the window is held in position both by the siding and the casing. The Utility window requires only two sizes of glass, four lights 12” x 20” and two lights 13” x 20”. The windows are first bed puttied, then the glass is inserted and held with glazing clips and the face putty is applied. Clips, cam handle and stay bar are wired to each window for shipment. The new Fenestra Utility Window is designed to permit easy and economical installation. Below are some installation features of particular interest to architects, contractors and builders. It is adapted to all standard types of construc- tion—brick, tile, concrete block, poured concrete, stucco and frame. Over-all dimensions fit concrete block—2'4 blocks wide and 6 blocks high, including sill. Comes complete—frame, sash, hardware, and a priming coat of paint. Projecting fin at jamb imbeds into masonry, forming a wind-proof, weather-tight anchorage. In brick construction two guides at each side of jamb fin enable mason to lay up both inside and outside courses without danger of fouling sash.

Each of these types is, in turn, made in “Channel” and “Tubular” design, and to fit single or double door openings. Orders should always give accurate dimensions of the door openings. The width dimension is measured from back to back of door frames. For the height, the dimension is measured from back of overhead channel to finished floor line. Atypical installation of a Fenestra standard single swing door, used in combination with standard Fenestra Sidewall Sash units. Notice the door opening isentirely ‘“‘ bricked in.” E Here is a pair of Fenestra standard double swing doors. High steel kick plates, heavy hardware and rigid con- struction make them practically indestructible. Fenestra Swinging Doors Fenestra single swinging and double swinging doors are manufactured in two types: 1—Steel Channel Trim Doors. 2—Steel Tubular Doors. These types are limited in width and area as indicated on page 107. 1—Channel Trim Doors Channel Trim Doors are made from heavy rolled, solid steel, U shaped chan- nels butted together over solid corner castings, through riveted, with counter- sunk rivets, to insure perfect rigidity. Lower panels are provided with steel . kick plates to a height of about 4’, the upper panels being glazed. Glazing angles are furnished as standard and 4"' wire glass should be used. Standard Fenestra latches or locks, butts and weathering plates are pro- vided where needed. Special hardware, such as door checks or anti-panic hard- ware, may be had at additional cost. 2—Tubular Doors Tubular doors are made from heavy rectangular steel tubes, mitered and welded at the corners. Kick plates and standard Fenestra hardware are supplied as in channel doors. 105 Standard Sizes Fenestra Single Swing Doors have been standardized in accordance with the following table of widths and heights of door openings: Width Height He oO” 9 64 OO he { ie 64 RY (4 Ge 0” Se OR arta.

Semi-Standards Where it is necessary to design open- ings for either channel or tubular doors in dimensions other than the standard, multiple of 6’, try to make use of 2” dimensions, (for example, 3’ 8’’ x 8’ 2’). Odd inch dimensions such as 4’ 5" are not desirable. Never use fractional inch dimensions, such as 4’ 614”, for either width or height. Erection Installation of swinging or sliding steel doors is an undertaking that should not be handled by a novice. Steel doors are not like wood doors which can be planed to fit. It is ab- solutely necessary that steel door frames be accurately made and that the doors be hung plumb and true. Our Service Department, The Fen- estra Construction Company, is com- posed of men who have had long experience in erecting both steel sash and steel doors of various designs, and we strongly recommend that the customer avail himself of this service. 0002 OPENING 200R OPENING ALWAYS GIVE THIS D/MENS/ON ALWAYS GIVE THIS O/MENSION.

Unless specifically informed otherwise, we always designate a swinging door as a “‘left open in door,” “right open in door,” ‘left open out door,” or “right open out door,” in accordance with the diagrams shown on this page. The “outside” of an outside door is naturally the one exposed to the weather. Where interior doors open from hallway, the hall side is always considered the outside. Where interior doors connect two rooms, a rough sketch, showing which is to be considered the outside, should accompany the order. Fenestra Channel Door Frames We strongly recommend that all door frames be purchased locally, as they should, in all cases, be installed when the building walls are erected, so that they may be properly anchored. Steel sash and doors, on the contrary, should not be installed until the build- ing walls are practically completed. We will be glad to furnish drawings, showing details and dimensions of door frames, on request. Particular care should be used to see that frames are made to exact dimen- sions and erected plumb and true and solidly anchored. Where doors are surmounted by transoms or flanked by steel windows we strongly recommend that the build- ing construction be carried between the door frame and the frames of the win- dows as shown on page 105. Where the customer particularly de- sires that we supply door frames,’ we furnish, at extra cost, frames of 4’, 6”, or 8” channel, in accordance with standard types 1, 2 and 3 shown on this page. Types 1 or 2 are preferable as the frames may be installed with the walls and the doors may be shipped later with the windows which should be in- stalled in prepared openings. TYP EES TYPE -2 Recommended Door Frame Dimensions UVES 14 Channel frames for Sliding Doors may be used in almost any depth desired as they are not required to carry the load of the door.

They are similar in detail to swinging dcors of channel and tubular design but are equipped with standard Fen- estra sliding door locks or latches, as the case may be, and with proper tracks and hangers. Special hardware may be secured at additional cost. Specifications should always give the accurate dimensions of door openings. See top of page 105. Fenestra Sliding Doors are limited in width and area as shown in the illustrations on page 110. Standard Sizes Widths and heights of Sliding Doors have been standardized as shown below. These types can be supplied quicker and usually at less expense than doors that are not standard. Width Height 3/ On g i ( 7 0” Ai 0” 4 8’ 0” Oa 10! 0” 12707 10’ (a 07 5/ QO” 6/ 0” Where it is necessary to design doors in dimensions other than standard, try to make the width and the height some multiple of 6”. If it is impossible to design a door opening in multiples of 6”, then it should be designed in mul- tiples of 2’. Odd inch dimensions are not desirable and fractional inch dimensions should never be used. Where one dimension is special it is very desirable to keep the other dimen- sion standard if possible. Guide slot at sill of sliding door Each Fenestra sliding door has at the bottom a steel plate projecting down- ward into a slot in the floor, through which it slides when the door is oper- ated. This construction serves two purposes. First, it acts as a guide to keep the door in alignment when it is opened or closed. Second, the plate, fitting into the slot, serves as a weathering member between the bot- tom of the door and the floor. As a rule, the slot is formed by placing two angles back to back in the floor with a space between them wide enough to accommodate the plate. These angles are not supplied by the Detroit Steel Products Company. 109 Detroit Seamless Steel Tubes Co., Detroit Twenty Vertically Sliding Doors of the type shown above were installed here—an example of the varied door construction problems that are solved by Fenestra engineers. Operation is by a worm and gear device located in the center of each pair of doors. This turns a shaft which carries pulleys over which the doors are balanced by counterweights.

They are manufactured from mould- ed sections of solid, rolled steel with doors of heavy U shaped channel, and mullions and door frames of 16 gauge formed steel plate. The framing member around each unit is an equal leg solid rolled steel channel shaped section. Base plates of 14 gauge steel are inserted between muntins to a height of 36’.. The upper portions should be filled with 144” clear or opaque glass. Glass and base plates in the doors are held by glazing angles. In the fixed sections, spring clips and putty are satisfactory. Laying Out A Partition Never, under any circumstances figure on a combination of partition units that will exactly fill an opening between columns. Always try to run the partition on one side of the col- umns or the other, or if it must go be- tween columns allow several inches at each end for filler plates or plaster. This is absolutely necessary to take care of inaccuracies in building con- struction and to allow for radiators, bases, window sills etc. For the same reason never figure on a parti- tion unit coming tight against the ceiling. Let the mullions run up to the ceiling but keep the partition units down. The intervening space is necessary to allow for column caps, sprinkler pipes, fixtures, etc., and may be left open entirely, or filler plates may be fitted around the obstructions. Sometimes it is feasible to use metal lath and plaster, but this work is not handled by Detroit Steel Products Company. First determine the total length of the partition. Let’s assume it is 125’. Next establish your mullion centers repeating the same units as far as possible so that your mullions will be spaced symmetrically. You will want to use the 4-light wide Diagram of Interchangeable Units. ip pee TTL SHS fe Be eae Photographs show enlargements of details indicated. units if possible (see page 112) as the larger the unit the fewer the units and mullions needed, and the lower the cost. Take the Unit Dimension (which is the center to center dimension—6/43%”’) and you will find 19 of them (either fixed light or with doors) will fill 120’ 114%". You will therefore have 4’ 0%" over. You can insert a 2-light wide filler panel which will be 3’ 154” wide and the remaining 1114”’ should be filled with filler plate. Interchangeability By loosening two mullions any three 111 light or four light wide unit may be removed without disturbing the rest of the partition. Units containing doors may be inserted in place of fixed units, or vice versa. For example if a door were suddenly needed in the fixed portion of a partition already in place, a standard unit could be re- moved, and a unit of exactly the same size, but containing a door, could be purchased and slipped into place.

Each type is made in three different heights and two different widths as shown on this page. Filler panels ‘‘A” and “B”’ are made in heights corresponding to the interchangeable units. Units which include doors are shipped knocked down,—that is, with the door, the door frame, the mullion, the fixed side panel and the transom sash, if any, allseparate. In assembling such a unit, the door must always be hung from the mullion, which is re- inforced to receive the butt screws, but the side panel may be used on either side of the door. The two light wide side panel ‘“‘B”’ is not interchangeable with the two light wide door. In laying out a partition, remember that 2’’ must be allowed for each mul- lion and that partitions require a mul- lion at each end. Thus, a partition composed of three units would require four mullions. SASH BAR C, YD N S < Ne Q . a) & S Nj ‘ < tS) « < S a) Y VERTICAL SECT/ION THRU DOOR.

Typical Layout of Corridor Sash The high cost of office space is in- Standard Installation Details creasing the popularity of small offices where desks are kept to minimum size, and filing cabinets, storage closets and so on are carried well up toward the ceiling to save floor room. The tendency in office buildings therefore is to build the partitions solid ‘ S up to about the height of the door, 5 3 using windows and transoms near the - P oF | EAD 8-3 top of the partition only. Fenestra Corridor Windows are ideal for this purpose. Standard types are made in 2-light wide fixed, 3-light wide fixed and 2-light wide ventilated. Each type is made in three glass sizes—20” x 30”, 24” x 36” and 28” x 40’... Where many windows of the same size are needed as is usually the case in large office buildings, special sizes can be handled without material difficulty. In the ventilated type the glass is cut down 1” along the outside edges. 17 | SASH OV.

Steel windows must be designed like an automobile or a typewriter to give the service the customer expects. That is part of any well made product. But after that, there are at least five other points in which steel windows are unique: 1—They must be laid out proper- ly in the architect’s plans to produce the desired results with maximum economy. 2—They must be estimated correctly for each individual operation, to give the con- tractor accurate figures for use in making up his bid. 3—They must be detailed accu- rately so the architect can be sure they will fit properly with other materials. 4—They must be delivered when needed, because a delay may retard the entire building. 5—They must be properly erected because only when they are in a wall does their real service become apparent. Fenestra recognizes and assumes this five-fold obligation. Fenestra Design Fenestra design does not need elabo- ration. As the makers of the first steel windows in America, and as pioneers in most of the improvements in steel sash since that time, we feel that our broad experience and engineering skill are reflected in a product which always has been and still is recognized as the standard. Fenestra Layout Every Fenestra representative is thoroughly equipped to advise with architects and engineers as to the most efficient window layout for his particu- lar building. We welcome requests for assistance of this kind, and give it promptly, absolutely without charge or obligation. Fenestra Estimating Every Fenestra Sales Office is equipped to give quick and accurate estimates on windows for practically any type of building. Local Detail Departments in all Branch and Dis- trict Offices handle rough sketches and details and co-operate with the Sales Department to give a double check on the accuracy of all figures. Fenestra Detailing We make detail drawings on almost every large operation and submit them to the building designer for his check- ing and approval. This is work that calls for close co-operation between the material maker and the architect, en- gineer or contractor. Almost in- variably, changes are desired on one side or the other—plans must be checked—dimensions O. K.’d. Every step carries the possibility of misunder- standing and delay. To insure prompt and _ intelligent service, all work of this kind is handled by Fenestra through Branch Office and District Office Detail Departments, especially maintained for this purpose. They have authority to settle details without reference to the Home Office. No orders are accepted at the factory until approved by the Head of the Detail Department in the territory from which they come. The advantages of this plan are numerous: It assures the building designer that he has a man near him who understands his work, and There is a considerable difference between the two. with whom he can discuss and settle difficult points quickly, and usually in person. It provides a means of giving the architect, engineer or contractor immediate service in case of need. Our men have submitted drawings within an hour after the request reached them, It insures, on our part, a clearer understand- ing of what is needed than would be possible if the details were handled by correspondence from the Home Office. It gives our detail men a personal contact with the builders in their territory, and with this contact comes a real enthusiasm to see that they are served promptly and well. It eliminates a tremendous waste of time and a large volume of correspondence, irksome both to the customer and to ourselves. Manufacture and Distribution Orders arrive at our factory—clean— the first step in accurate and prompt manufacture. The most popular types of Fenestra are stocked in a score of warehouses over the United States, to provide im- mediate delivery. The next most popular types are kept at Detroit, with bars machined and ventilators in stock, ready for final assembly and shipment. In Oakland, California, a branch factory is equipped to supply Windo- Walls for buyers west of the Rockies, thereby saving time and freight charges. A similar branch factory is located in Toronto to supply Canada. Erection And finally, our Erection Depart- ment—The Fenestra Construction Company—with 10 branch offices and 27 experienced field superintendents, insures that our product will be cor- rectly installed. These offices assume the responsibility as soon as the sash leave the factory and carry the job through to completion, and final approval. We believe, therefore, that ‘‘Fenestra’’ has much more to offer the pros- pective buyer than merely a carefully made product of national reputation. We would like to have you think of Fenestra as a service which includes all of the essentials, which together produce a ‘‘satisfactory window installation.”’ 115 Index of Catalog Sections PAGE TIORIZONTALLY PIVOTED SASH. oe ee ad oe 3-16 WONSTEUCTION aap oe eso een ee ye Dass Mechanical Operator ?.4; os8 ts se ee 5 Horizontal Mullions (Structural)......... 6 (Glass Sizes." eee gee a ee a ff Warehouse Stock!lypessc.). 7 saan ae. if Slandardsstock#hypes.n +. voy ae omer 8, 9 Prepared Openineseates ta kc. ee 10 Tnstallation: Detailstenjc es sc ... ... ... 40s 49-52 tension OpetatOtmed.
