FRAME AND VENTILATOR BARS The outer members of the sash and ventilator frames comprising the top, bottom and two sides consists of ONE CONTINUOUS, SOLID SECTION STEEL BAR, BENT ROUND AT THE CORNERS (see engraving), and the two ends coming together is strongly spliced and welded. This continuous feature of the outer frame member makes the sash and ventilator at the four corners inflexible and unbreak- able. It also prevents the sash from becoming twisted and warped out of square. No other sash manufactured has this superior quality. CORNER OF SASH, OR VENTILATOR, SHOWING ONE-PIECE CONTINUOUS FRAME BAR. INSIDE ViEW. SAME CORNER, CUTSIDE VIEW, GLAZED PIVOTS The Mesker pivot is patented. It is not a hinge or an attachment of any kind, therefore, no plates, bolts, nuts, pins, or other loose parts are required in its make up. It cannot rust tight when not in use. Its superiority lies in the simplicity of its formation. THE MESKER PIVOT. PATENTED. SHOWING STRAIGHT GLASS RABBET vided on which the ventilator balances perfectly on its own axis and yields to the slightest touch of the push bar or chain operator. The pivot feature of the ventilator does not affect the alignment of the glass rabbets, they are as flat as the glass itself. The Mesker pivot permits the ventilator to be removed by window cleaners without the use of tools, and to be replaced without readjustment or refitting. VENTILATORS The weathering features of our ventilators are designed in accordance with the well-known principle of flat straight surface contact, overlapping the muntins three-eighth inch all around, which is preferable to the point or butt contact, making a continuous flat weathering, thoroughly rain proof. Ventilators are made entirely by machinery, assuring a closely-fitting, well-balanced sash, free from the uncertainty of hand labor, at the most important part of the window. Weep holes or drains are provided at sill of ventilator near the jamb, to carry off inside condensation. A fulcrum bearing is pro- When ventilators extend to both sides of window, keep sash slightly away from masonry to prevent ventilator from binding against the wall when opening. JOINTS The joining of horizontal and vertical muntins if formed by a special (patent applied for) dovetail wedge and miter. Where the muntins intersect the frame bar, a double two-way mor- joint aFTER ASSEM- tise and tenon feature is BLED, SHOWING employed, as shown by CAULKING FEATURE, engraving. The joints being interlocked by powerful presses gives the sash great strength against wind pressure. Hand power in the manufacture of our steel windows is entirely elim- inated, assuring a perfectly fitting and high-class article impos- sible of attaining by hand-made process, JOINT OPEN, SHOWING DOUBLE MORTISE AND TENON, BEFORE ASSEMBLING. PUSH BARS Push bar sash adjusters are furnished for all ventilators, unless otherwise specifically mentioned. They are made of heavy rolled bar iron, connected with strong eye bolt to steel angle bracket, securely fastened to bottom of ventilator. Notches in edge of push bar fit over edge of weathering angle, enabling the ventilator to be opened at any required position. When ventilator is closed the push bar is folded back, inserting its notches. into loops in weathering angle securely locking the ventilator. THE MESKER PUSH BAR VENTILATOR LOCKED CAM LOCK AND CHAIN HARDWARE The cam lock is of heavy steel construction, connected to angle bracket with strong swivel bolt, and securely fastened to bottom of ventilator. The chain is fastened to top of ventilator by heavy steel ring, and holds the ventilator open at any desired angle by fastening the chain to cleat on wall or to hook at bottom of sash.

They have the distinctive feature of matched tongue and groove boards, making them rainproof, wind- proof, and dustproof. Other superior qualities of our mullions are: They have no unsightly bolts and nuts, or expansion slots, to mar their appearance or cause trouble in erection. They have no seams to spread and admit water. They have two inches of continuous weathering contact. The tongue and groove feature provides for expansion and contraction, also for the most rapid installation at a reduction of 20% in cost.

They are readily adopted by Architects and School Boards for the most perfectly operating windows without projecting the sash into the rooms. When open, the ventilator serves either as a rain shield or as an awning as well as for ventilation. 101 102 103 OPENING 20! 202 ON TOP, AND AT SJDES HEREWITH, ee ee 6- 146" © —— MEASURE — 30! 302 GLASS SIZES ARE IND 40) 4 VENTILATOR LI TYPE The Extending Ventilator opens out at the bottom, causing the top to slide down vertically. This is accomplished by means of a pull chain fastened at the top. which projects the ventilator outwardly at the bottom. The slam, heretofore experienced when closing other types of sash is entirely eliminated in the extend- ing type. The necessary friction for the successful operation of this type of sash is developed by our special construction of sash bar. Has no springs or bolts to be adjusted, but a vertical slide arrangement of utmost simplicity, requiring the least STANDARD SIZES effort to operate. The self balancing ventilator automatically adjusts itself to any angle, from the vertical to the horizontal plane, giving window cleaners full access to the outside of the glass. Another distinguishing feature of the Extending Ventilator is that it admits the attachment of window screens, on the interior as well as window shades and draperies. CONSTRUCTION The sash and ventilator is constructed of solid rolled open hearth steel section. The outer frame consists of ONE PIECE CONTINUOUS STEEL BAR, bent round at the four corners and welded at the splicing of the two ends. The muntins, also of solid steel section are tenoned at the ends and mortised into the frame members. And when caulked by heavy machinery makes the sash of greatest possible strength, and perfectly square and true, so that they cannot be racked out of shape by careless or rough handling. No other sash manufactured has this superior ONE-PIECE FRAME BAR FEATURE. MULLIONS The Mesker PATENT Mullions are designed to be used to join a multiple of units in large openings for lighting class rooms, auditoriums, hospital wards. etc. They are constructed of No. 14 or No. 16 gauge steel, and formed into the distinctive feature of matched tongue and groove boards, and are rainproof, windproof, and dustproof, They have no unsightly bolts, nuts or expansion slots to mar their appearance or cause time or trouble in erection. And no seams to spread open and admit dust and water. The tongue and groove feature provides for expansion and contraction and also for the most rapid installation at a reduction of 20% in cost. See page 11 for special types of mullions designed to substitute stone, terra cotta or wood. These mullions may be -cz-rste filled and plaster finished on the interior and they-present on crchitectural finish on.the exterior *-2~ 1 STANDARD SIZES The sizes of units for this type of sash are the same as for the standard center pivoted type. Customers sending inquiries regarding this type of sash should refer to unit numbers given. 9 For high windows where an upper and lower ventilator is desired as in Nos. 501-502-503 it is recommended that the lower one extend in at the top and the upper one extend out at the bottom. ; : : ; ? One hundred percent ventilation is obtainable with the extending ventilator, but maybe opened to any desired angle without the use of push bar or any other fasteners. GLAZING Our glazing clips, of special design, are devised to hold the glass firmly in place. Holes are provided in the muntin bars for the clips—four or more to each light. The clips take up the variation in thickness of the glass. Special steel sash putty should be spread on the glazing rabbet and the glass forced into same, completely filling the entire space between the glass and the steel. Do not use ordinary putty, it dries out and breaks away. Excess putty should be struck off and glass face puttied. HARDWARE The extending ventilator is operated by an en to th.

IS S CONCRETE CONSTRUCTION WOOD CONSTRUCTION The Mesker Steel Basement Windows are made in two sizes and are constructed of solid rolled open hearth steel sections throughout, %” thick. The outer frame bars of the sash and ventilatcr are made of ONE CONTINUOUS PIECE OF SOLID ROLLED STEEL SECTION welded together at the ends. This makes the sash of greatest possible strength, and perfectly square and true, so that they cannot be racked out of shape by careless or rough handling. No other sash manufactured has this superior ONE-PIECE FRAME BAR FEATURE. To install Basement Windows the mason lays four or five courses of brick, leaving a half inch groove in the brick jamb on each side. Slide the sash down into these grooves, the projecting flanges of the sash extending into the grooves. Then build up the walls encasing the sash flanges into the brick work, and neatly point up with cement mortar all around. In concrete walls a rebate should be formed in each jamb and the sash is slipped down from the top into the rebate and grouted securely. The Mesker pivot is patented. It is not a hinge or an attachment of any kind, therefore no plates, bolts, nuts, pins or other loose parts are required in its make up. It cannot rust tight when not in use. Its superiority lies in the simplicity of its forma- tion. The Mesker Pivot permits the ventilator to be removed by window cleaners without the use of tools, and ts be replaced without readjustment or refitting. The lock is of heavy steel securely riveted to ventilator. A slotted seat is pressed into the frame for latching and insures absolute weathering. There are no springs, bolts or nuts to rust or get out of order. Steel glazing clips to hold the glass in position are furnished. A good grade of steel sash putty should be used. Putty should be spread upon the glazing rabbet and the glass forced into same, completely filling the entire space between the glass and the steel. Face putty the glass and neatly strike off excess putty. Our basement windows come complete ready to install in brick, stone, concrete or wond walls. They are serviceable, econom- ical, easy to operate> Thé ventilator is pivoted at the top and swings in at the bottom and can be fastened to ceiling. When “ open 100% ventilation is obtained. They have more lighting capacity than wooden windows, better in appearance, they are fireproof, they cost less and they last longer. The Mesker Basement Windows are easily installed, the flanges of the frame extend into the masonry, and they are built in as the walls go up. The steel flange along the top rail extends up into the lintel construction, and the lower rail is grouted into the window sill on the inside. These windows have a priming coat of paint before leaving the factory. Standard wooden screens may be used with basement sash from the outside. See detail above.

HARDWARE—Lock of the cam acting type and handle of artistic design, in brass finish, is attached to bracket of each sash. Sturdy Steel hinges of brass finish and removable pins connects the sash to the frame. A jointed friction adjuster restrains the sash when open and holds it in the desired position. LEADED ART GLASS CASEMENTS—When Cottage Casements with small lights are required as shown in right hand corner above, a vertical 34” solid secticn T bar muntin is furnished with heavy leaden horizontal sash bars, shipped separately. They are to be attached to sash when glazing is being done. Clear, colored or translucent glass may be used for such artistic effect as may be adapted to carry out the desired design. INTERIOR FINISH—Since wood interior trim is not considered a necessity in modern homes, and as sanitation is being more carefully observed in building construction, plaster finish is preferably recommended for sides, head and sill of the interior where the Mesker Casement Windows are used. WEATHERSTRIPPING— Our (patent applied for) metal weatherstripping attachment to solid section steel sash is of the utmost simplicity and cost les weather stripping wooden windows and much neater in appearance, and prevents rattle, and is rainproof, windproof, and dustproof. The cost is only extra. Weather strips may be preferred for their neat appearance, softness of closure and air tight qualities. They are made of No. 11 gauge zinc, « gauge spring bronze and furnished only when ordered. Weather strips may be attached to our casements by owners subsequent to receiving the wind< may be attached without the assistance of a skilled mechanic before glazing. No practical method has been previously designed for fastening ™ strips to steel sash. ‘The means employed in the Mesker method is of utmost simplicity and practicability. With this latest achievement in wi no triple contact is necessary since the weather strips are secured to the sash. The Mesker metal weather stripped, air tight, casement rival for their artistic beauty and superior qualities. Weatherstripping not included in above prices. MESKER MONITOR STEEL SASH 1—See details.

These partitions are made up of standard units of solid rolled section steel sash, designed to be artisticaily grouped with the Mesker tongue and groove mullions for any condition, dimension, or arrangement of plan. Partitions designed from our standard sizes, given on page 10, can be delivered from stock and at much lower prices than when specially designed. The wainscoting portion of these partitions are paneled with heavy steel plate, and the upper panels are glazed with ribbed, florentine, wire, plate or window glass. Partitions should be, as far as possible, When arranging for steel partitions, it is advisable to avoid coming in direct line between existing columns. run clear of any obstruction. The partition illustrated above is approximately 7 feet high, leaving ample space for the circulation of air and heat. Where it is desired, the entire enclosure may extend up to the ceiling by filling the space between the sash and ceiling with metal lath and plaster, or with steel plates. In such construction the mullions should run from the floor to the ceiling. In most cases, it would be impractical to extend sash to ceiling and fit around sprink- ling systems, steam pipes, beams, girders, and other obstructions contiguous to the ceiling. Ventilators may be placed in the sash at any desired location. The Mesker design of mullions makes it possible to readily remove partitions, which so often is required, and permits them to be taken apart. No be"*+ nuts or pins to be removed. Any or all units may be re-erected without removing the glass. Doors are manufactured from heavy rolled open hearth steel, welded at joints. Latches or locks and bolts are provided where needed. Doors vor frames are not drilled for hinges or door checks. This should be done by the contractor erecting doors to insure correct fit. An~ ordinary mechanic may install the Mesker Partitions with utmost simplicity, they fit like matched tongue and groove flooring after starters At wall and floor.

VERTICAL SECHONM. COUNTERWEIGHTED. ERTICAL SECTION. COUNTERBALANCED. TY PES—The most desirable types in this class cf window are the Double Hung (or counterweighted) and the Count®enlanced Windows. These are especially suited for Business, Educational, Institutional, Industrial, Public, Residential and Recreational Buildings. UNDERWRITERS LABELED—These windows are subject to the rigid requirements and inspection of the National Board of Fire Underwriters, bearing their label of approval and accepted by rating bureaus everywhere in the United States and Canada as Standard Underwriters’ Windows. NON-LABELED—The non-labeled windows ere of the same construction as the iabeled, ex-ept that the glass in the non-labeled windows is held in place with steel giazing clips and putty, instead of steel glazing angles. CONSTRUCTION— The heads, 3 ills and jambs of the windows are made of No. 16 gauge steel, or No. 24 gauge galvanized steel. Grooves are formed in the frame to receive the projecting flanges of the sash members. The sash operates in the grooves with a vertical movement and insures easy operation and is perfectly weathertight. ACCESS TO WEIGHTS, DOUBLE HUNG WINDOWS—The grooved members of the jamb in the Double Hung Window are adjustable for the double purpose of removing the sash should occasionr equire, and for giving access to counter-weights after the window is installed. COUNTERBALANCED WiNDOWS—This type is recommendedi n preference to the Double Hung type. The frames are constructed of No. 16 gauge steel with grooves formed to receive the flanges of the sash members. The grooves permit perfect weathering and easy operation ofthe sash. The two sash counter- balance each other being hung on chains which pass over pulleys in the head. When open, the window allows 50% ventilation, heated air escapes through the top, and fresh air is admitted through the opening at the bottom. CONNECTION LUGS—The sill and head is secured to the jambs by a series of angle lugs riveted to the sill and head and fastened to the jambs by tap screws threaded into the lugs. (See illustrations.) MAY BE KNOCK DOWN —These types of windows may be furnished KNOCK DOWN form, thereby saving a considerable amount in freight cost. When so ordered, they are shipped in parts and assembled on the job. The cost at the factory is less. The cost of assembling at building must be added. The subsills are filled with concrete at the building. Instructions for assembling accompanies each order. SASH CONSTRUCTION—The sash is constructed cf solid rolled open hearth steel section. The outer frame consists of ONE PIECE CONTINUOUS STEEL BAR, bent round at the corners and welded at the splicing of the two ends. The muntins are also of solid steel section, mortised at the ends and tenoned into the frame members. making the sash perfectly rigid and cannot warp out of square.—Continued on page 13. = —=20— Wester Bins, Foon On stctecissta MESKER FIREPROOF HOLLOW METAL WINDOWS Approved by the National Board of Fire Underwriters.
