It has not been attempted to give complete engineering or sales data, which we would be glad to furnish on request from any of our district sales offices. It is hoped that this booklet will be properly filed and referred to from time to time. All Havemeyer Products are the result of careful study with the aim of furnishing the best possible article for its particular purpose. Around these products has been built up the Havemeyer Service, which brings to the job any of the products shown in this catalogue that may be required. There are many dis¬ tinct advantages to the architect, engi¬ neer and contractor to be gained by al¬ lowing one company to furnish all ma¬ terials in its line required for a n v r/fw of a section of a Concrete particular COnStruC- Steel Co. shop, henditKj Contin- . . , uous Stirrup Reinforcement tlOIl JOb. We carry large stocks of Havemeyer Bars and Building Products in our warehouses lo¬ cated at central points of distribution. Each warehouse is equipped with the most modern labor-saving devices for handling our prod¬ ucts, bending and fabricating Havemeyer Bars, manufacturing spirals and other devices required in reinforced concrete construction. 'Fhis equipment is at your service—we are al¬ ways ready and willing to serve you. Concrete Steel Company also maintains district sales offices located in principal cities, and in addition it maintains sales agents and distributors in other large cities. This com¬ plete sales force is ready to render you any assistance possible on any concrete or fireproof structure, regardless of its location. We maintain an engineering depart¬ ment in all of our sales offices, whose services are at the disposal of our cus¬ tomers, and our en¬ gineers are prepared to furnish you any detail which vou Column Ties, bent, bundled and tagged—all machine ’work—at a Concrete Steel Co. ’warehouse [ 3 ] HAVE MEYER BARS and BUILDING PRODUCTS may require for the construction of your building. After you have placed your order with us, it is our business to get whatever materi¬ al you order to your work on time. Delays are always costly and where Havemeyer Service is employed, you can be assured that your order will receive prompt attention and materials ordered will be delivered to your job as required. Havemeyer Service is the result of twenty years of practical experience, beginning in the construction field and later developing into a service organization. Requirements of the contractor had to be studied, and our many years of experience in the field, together with the many large building operations which we have carried forward, during good and bad periods, assure the contractor the very best possible organization behind every order he places with us. To the architect or engineer who specifies Havemeyer Products, we can as¬ sure every possible advantage for the owner and contrac¬ tor, always endeav¬ oring to make our prices as low as pos¬ sible consistent with quality. Shop Bending We would call the particular attention of the engineer and contractor to our facilities for shop bending and shop fabricating of Havemeyer Bars. This service is one which was originated by this company and has been built up during sixteen years of study and labor. Shop bending as¬ sures the contractor that the bars are correctly bent, tagged and are ready to place in the forms. This bending is done entirely by power machines, designed and built in our own shops and operated by experienced men. This is more economical than to employ men in the field, who necessarily must do a large part of the work by hand. It saves the contractor one operation and one less gang of men to look after. We would be very pleased to study any Assembled Bridge Slab Rein- fnreement being loaded at a Concrete Steel Co. ’warehouse Concrete Pile Reinforcement, fabricated in one of the plants of the Concrete Steel Co. Boston fVarehouse and Shops, Concrete Steel Co. [I] CONCRETE STEEL COIMPANY Modern Daylight Plant mid Warehouse of Concrete Steel Co., at Chicago job, no matter how difficult, furnishing the bars bent and fabricated ready to place in the forms. This service is the most modern and economical method of furnishing reinforcing steel, and too much cannot be said of its many advantages. We have attempted in this book¬ let to give a few illustrations showing some of the important steps in our warehouses towards furnishing fabricated steel for various types of jobs. In addition to shop bending. Concrete Steel Company have been pioneers in furnish¬ ing new devices for holding the bars in their proper position while the concrete is being poured. These devices are economical and money savers. We have also developed a complete line of wire products, which we manufacture on auto¬ matic machines in our own shops. Bar-Tys are made from spring wire and make an absolutely rigid tie. Other forms of wire de¬ vices consist of Easel Chairs for holding the bars in small beams. Extension Clips for fire¬ proofing purposes in steel buildings, etc. Havemeyer Collapsible Spirals are manu¬ factured in our larger shops, and ordinarily are shipped to the job fully assembled and col¬ lapsed. All spirals are made with rigid angle spacers, the size of the angle used depending on the diameter and length of the spiral. Havemeyer Spirals have proven uniformly satisfactory, and unless otherwise specified these spirals are made with two spacers. Extra spacers can be furnished, either assembled on the column or loose, in order to give addition¬ al rigidity. Hot rolled rods are ordinarilyused for coils, but cold drawn wire can be furnished if required, at a slight additional expense. [5] HAVEMEYER BARS and BUILDING PRODUCTS Detroit Plant and Warehouse of the Concrete Steel Company Warehouse and Shops of the Concrete Steel Company at Youngstown, Ohio [6] CONCRETE STEEL COMPANY Engineering Staffj Headquarters Division of the Concrete Steel Co., supporting all branches and warehouses Havemeyer Engineering Service C oncrete Steel Company maintains an experienced and efficient engineer¬ ing department at every district sales office for the benefit of customers. These en¬ gineering departments will gladly co-operate with engineers, architects and contractors in making up designs, estimates and plans on any type of reinforced concrete structure—a serv¬ ice behind which are many years of experience in every conceivable kind of concrete rein¬ forcing problem. Our Engineering Department consists of especially trained engineers. We make up preliminary bids for contractors, furnishing lump sum figures which include all re¬ in forcing steel re¬ quired, together with specialties, such as beam saddles, bar- * spacers, Hy-Chairs, etc., including neces¬ sary bending, bund¬ ling, tagging and delivery of steel as re¬ quired, floor by floor. We make up bending details and furnish to our customers a complete list of steel required on the job, showing the location of each bar whether bent or straight, and also furnish any necessary erection plans, making original de¬ signs where required. In other words, we take a building laid out by the architect or engineer and make up the complete design, together with working draw¬ ings, erection details and plans showing the location of all reinforcing steel. Frequently we can find ways of effecting substantial economies in construction costs. A moderate charge is made for this Engineering Service. Whenever the slightest element of doubt arises as to the proper use of Have¬ meyer Products, the Concrete Steel Com- pany’s engineers stand ready to dem¬ onstrate the efficiency and helpfulness of Havemeyer Engi¬ neering Service. [7] HAVE MEYER BARS and BUILDING PRODUCTS To bring the steel to your job on time—a typical plant siding—an important phase of our service at all warehouses Unsurpassed Havemeyer Bar Service AVEMEYER Bar Service today is the result of a careful study of the eco¬ nomical distribution of concrete re¬ inforcement and building products. On the one hand, we have the large steel mills, equipped with modern, high-speed, continu¬ ous rolling mills, manufacturing steel bars in large quantities; while on the other hand we have a given building operation, requiring steel deliv¬ ered on the job from day to day, week to week and month to month as the job pro¬ gresses. The con¬ tractor naturally wants the steel deliv- ered in accordance with the progress of his work, starting usually in the case of a building, with the footings, basement columns, retaining walls, and then on up to the various doors and the roof, pent house, coping, etc. The steel required must be cut to various lengths, with bundles properly tagged so that each can be readily identified. If the work is located in a large city we can deliver in truck-load lots, working as closely as possible to the contractor’s con¬ struction schedule. Where material is shipped in carload lots, the same pro¬ cedure is followed. With the con¬ tractor, speed is usually essential, be¬ cause speed means the saving of dollars in overhead and often means extra money in bonuses. Delays in the delivery of re¬ inforcing steel are serious, for when the Our larger warehouses are equipped with machine shops and special machinery—the best facilities are at your disposal [8] CONCRETE STEEL COMPANY material is not on hand, construction work must stop, and any building operation closed down even for a day may mean the loss of thousands of dollars. Havemeyer Service has been thoroughly and carefully organized so as to safeguard the contractor against delays. Building operations are carefully studied by our engineers, and our delivery schedules fit in closely with the sched¬ ules laid out by the contractor. M’hile the contractor wants to be sure that his reinforcing bars will not be delayed, it is equally important not to have this material arrive on the job too far in advance of the time it is needed. This also is expensive for the contractor, as bars become misplaced, rusty and usually require re-handling many times. In addition to this, the contractor as¬ sumes a financial obligation which he must meet and on which he cannot realize for perhaps several weeks or months. Havemeyer Service avoids this unnecessary expenditure, and by co-ordinating our shipments with the requirements of the contractor, a much smaller cash investment is required in his work. Havemeyer Bar Warehouses are located in all the larger cities and principal shipping centers throughout the United States, with an additional list of dealers handling our ma¬ terial in smaller cities. Our organization has been built up of district sales offices in charge of competent and experienced sales managers. We can quote on a job anywhere in the United States from any one of our district offices, and each district office is prepared to enter orders Bending Bars to exact details—interior view of one of the many fabricating shops of the Concrete Steel Company direct with any of our warehouses. This service has proven very valuable and a big time saver. A contractor located in one city and figuring on a job in some other part of the country can get full and complete information from our district office nearest to him. Equipment Each of our warehouses is equipped with the most modern machinery for handling, shearing, assembling, bending and fabricating reinforcing bars. These machines have been designed and built in our own shops to meet our own special needs. Our facilities for shop bending are unsur¬ passed. Many different types of bar benders are used, depending on the type of bend re¬ quired. These bar benders have been de¬ signed by us to do the work quickly and eco¬ nomically. Shop bending today is well estab¬ lished among the best contractors in the coun¬ try. Bars can be bent in our warehouses much cheaper than on the job, and in addi¬ tion the contractor has the satisfaction of knowing that when the bars are placed in the forms they are bent true to detail. Many engineers and architects are specifying shop bending on their work on account of the greater accuracy and economy than would be possible if the same work were done in the field. Havemeyer Service, therefore, starts with estimating the job and ends with the delivery of the last lot of steel, bent, fabricated and ready to place in the forms. Bent Reinforcing Bars ready for delivery—another vieiv of a typical Concrete Steel Company ivarehouse [9] HAVEMEYER BARS and BUILDING PRODUCTS Havemeyer Bars AVEMEYER Bars are rolled in Round, Square and Flat sections and are de¬ signed to meet the necessary require¬ ments of a mechanical bond in concrete and at the same time maintain a constant cross section equal to that of a plain bar. The de¬ formations in the bar run longitudinally and enter directly into the tensile strength of the bar, no metal being used for mechanical bond only. This means a bar with a strong mechan¬ ical bond, rolled to the same weight, area and strength of a plain bar, thus effecting a consid¬ erable saving in weight of metal over other types of deformed bars. In the case of the square bar, this constant cross sectional area is obtained by alternating plain square sections with irregular sections produced by depressing two opposite corners of the bar and raising an equal amount of metal on its four faces. On the round bar there are no depressions, but the projections on the adjacent faces are staggered. The same is true of the flat bar. Havemeyer Flat Bars are designed par¬ ticularly for construction requiring bars bent to a radius, such as silos, grain elevators and sewers. These bars bend very readily, as the upper and lower flanges come in contact with the bending rolls, leaving the deformations ab¬ solutely intact. On all Havemeyer Bars the projections and depressions run longitudinally and rise and fall gradually, thus allowing a free and uninterrupted flow of metal while being rolled. These irregularities or deformations offer a mechanical bond or resistance in the con¬ crete which is more than sufficient to develop the strength of the bar, independent of the surface adhesion. Laboratory tests have shown that Have¬ meyer Bars develop maximum efficiency, will not pull or split the concrete and will not twist under stress. There are no sharp edges to start a fracture. Havemeyer Bars are rolled only from the highest grade new billet steel to any desired standard specification, at mills which do not re-roll rails, thus avoiding any chance of error. Great care is used in the selection of steel. By specifying and purchasing Havemeyer Bars, the risk of securing an inferior grade of steel is eliminated. [10] CONCRETE STEEL COMPANY Economy in Construction All Havemeyer Bars have a constant ef¬ fective cross-section and consequently are rolled to the same weight as a plain bar of cor¬ responding size, no metal being wasted to se¬ cure a mechanical bond in the concrete. Ac¬ cordingly the contractor can reduce his cost of reinforcement to a minimum, at the same time furnishing the desired area of steel. A strong mechanical bond is secured without increas¬ ing the weight of steel and consequently with¬ out increasing the cost. Havemeyer Bars will bend easily, because the metal in the projections follows the bend as readily as the metal in the body of the bar. The changes in cross-section of the Have¬ meyer Bar are gradual. There are no abrupt changes which tend to start cracks in the steel when bending. Havemeyer Bars can be easily wired at intersections, the projections and depressions preventing the wire from slipping. This is of particular advantage when placing vertical reinforcement. Havemeyer Bars are rolled on regular schedules in the Pittsburgh, Youngstown, Chi¬ cago, Birmingham, Buffalo and Kansas City districts by the largest and most modern roll¬ ing mills in the country. During periods of unusual steel activity, when a shortage of steel exists and concrete bars are difficult to obtain, the large number of rolling mills furnishing Havemeyer Bars assures us a steady flow of steel into our ware¬ houses, so as to maintain, at all times, uninter¬ rupted Havemeyer Service. Quality of Steel Havemeyer Bars are rolled to Manufac¬ turers Standard Specifications for Concrete Reinforcing Bars, New Billet Steel, using Structural, Intermediate or Hard Grade. They can also be furnished to o'ther standard specifications. There has never been a time since reinforced concrete construction became a factor in American build¬ ing, -when the engineer should pay more attention to the quality of steel entering into reinforcing bars, than at the present time. Great care should be exercised in the proper inspection of the steel that enters into a concrete structure. We would call particular attention to the fact that all Havemeyer Bars are rolled only from highest grade new billet steel, these billets being rolled directly from the original ingot, and every care is used to make sure that the purchaser is securing Havemeyer Bars of the quality of steel represented. This absolutely assures the architect, engineer, contractor and owner that only the very highest quality of steel will be used in his work. We consider this of the utmost importance.

They are usually made up with two spacers and shipped collapsed. Additional spacers can be furnished if de¬ sired. An angle spacer is used, the size of the angle depending upon the size and weight of the spiral. These angles give sufficient stifif- ness to hold the spirals in position when set in the forms. When properly handled the spirals re¬ quire no straightening after ar¬ rival on the job. The coils are made from either hot rolled rods or cold drawn wire, as ordered. Rods are correctly coiled to a true diameter and rigidly attached to Assembling Havemeyer Collapsible Spirals —specially trained workmen are employed the spacer, allowance being made for collapsing. Coils are attached to one face of the angle, so that the strength or rigidity of the angle is not impaired. After very careful experimenting, this was found to make the most efficient type of spiral. Havemeyer Collapsible Column The Havemeyer Collapsible Col¬ umn is made up by using Have¬ meyer Bars for longitudinal mem¬ bers and for bands. The bands are attached to the longitudinal mem¬ bers by the use of Bar-Tys. These columns are shipped collapsed and are readily opened and set in place. [12] CONCRETE STEEL COMPANY Havemeyer Expanded Metal AVEMEYER Expanded Metal is manu¬ factured in many different gauges and in a large variety of meshes designed for various purposes. The coarser or heavier meshes are used generally for reinforcing con¬ crete floors, roofs, bridges, sewers, retaining walls, etc. Expanded metal can be laid very rapidly by unskilled workmen. It is only necessary to lay the sheets in place with ends and sides lapping one diamond and to see that the sheets are kept the proper distance from the forms during concreting. This end lap is sufficient to develop the full strength of the steel and may occur at any point. Because of this meshed formation, a con¬ centrated load at any one point is immediately taken up and equally distributed over the en¬ tire area. Any tensile stress tends to compress the diamonds, and this in turn, is resisted by the concrete within the mesh. The smaller meshes are used for machine guards, partitions, and other purposes. We have a special type of expanded metal used largely to reinforce Burial Vaults. The strand of steel is about 3/32" wide, the expan¬ sions large enough to permit a free flow of concrete which eliminates voids. Sheets 24" X 96". Packed 16 yards to the bundle.

[13] HAVEMEYER BARS and BUILDING PRODUCTS Havemeyer Electric Weld Fabric AVEMEYER Electric Weld Wire Mesh or Fabric is used for reinforcing con¬ crete slabs in building construction, roads, sidewalks, and many other places where a light reinforcement is required. It is usually shipped in rolls, either plain or galvanized. In order to secure a variation in weight and area of steel, it is only necessary to use various sizes of wires and spacings. This flex¬ ibility in manufacture renders the Electrical¬ ly Welded Fabric the most popular type of wire mesh reinforcement. CONCRETE STEEL COMPANY This material can be furnished in rolls or in sheets. It can also be furnished in various widths, plain or galvanized. We carry in stock certain types for which there is the greatest demand, and there are other types which we can ship from the mill promptly. In addition to the types shown in the tables, other types can be supplied on order. Take up your requirements, whatever they may be, with our nearest district office, and we will give you prices, weights and areas on types which are not shown in the table.

Havemeyer Securo Slab Spacers are correctly spacing and holding bars and No. 2 Havemeyer Bar-Tys are holding bars rigidly together at intersections. Havemeyer Inserts are placed and job is ready for the concrete—all steel securely in place Havemeyer Spacing and Holding Devices HE proper placing of reinforcing steel is of the utmost importance. Rein¬ forcing bars must not only be properly placed in accordance with the engineer’s de¬ signs, but it is equally important that they be held rigidly in place while the concrete is be¬ ing poured. After the concrete is poured it is impossible to tell whether the steel is in its proper place or not, but the strength of the building depends entirely on the steel being placed in accordance with the engineer’s plans. While the concrete is being poured consid¬ erable pressure is brought against the steel due to tamping, screeding, etc. By using Have¬ meyer Supporting, Spacing and Tying De¬ vices, the owner, architect or engineer is abso¬ lutely assured that the steel is being held rig¬ idly in its correct position and that it will be in its correct position after the concrete is poured. These devices have been in use for many years and have met with popular favor on all sides. By using these devices an archi¬ tect or engineer will know that the steel is just where it should be and will be there when the building is finished. He knows that the floors, beams, girders, walls, etc., will carry safely their designed load. Havemeyer Beam Sad¬ dles, Slab Spacers and Hy-Chairs are made to order in our own shops to fill the require¬ ments of each particular job. During con¬ struction work, the inspector can tell at a glance whether the steel is where it belongs. Mechanical supporting and spacing de¬ vices are required by the building codes of many large cities and are specified today by leading architects and engineers all over the country. By using these devices the contractor places the steel very quickly and accurately, and the expense is very little, if any, more than the old-fashioned, slip-shod methods. [16] CONCRETE STEEL COMPANY Havemeyer Hy-Chairs 3 / 4 'Sq. DEFORMED BAR, MAX. BAR THAT CHAIR WILL TAKE. This chair is used par¬ ticularly on flat slab work for holding bars at any height off forms. It is made of very highest grade open hearth steel. The locking prong at the top keeps the bar in its po¬ sition and prevents it from loosening. These chairs are provided with nailing holes so that they can be securely fastened to the forms if desired. The bead gives it additional strength. Hy-Chairs are shipped nested and crated and are made up on receipt of order. Prompt shipment can always be made according to specifications. Havemeyer Secure Bar Spacers This spacer is used for correctly spacing bars in slabs and at the same time holding bars the required distance off the forms. It is made from highest grade hoop steel. The locking arms are quickly wrapped around the bars, which pre¬ vents their being displaced during concreting. Securo Bar Spacers are made on receipt of order and prompt ship¬ ment can always be made according to specifications. They are shipped nested in bundles and are easily handled on the job.

PLAN Havemeyer Beam Saddles and Separators These devices are used to hold the bars at the required dis¬ tance from the bottom of beams and girders. They are made from the highest grade steel, with locking arms which are easily closed. They can be attached to the bars before placing in the forms, and a complete unit assembled and dropped in the forms. If desired, the beam saddles can be placed in the bottom of the forms and the bars laid in the notches. Separators are used when two layers of bars are called for. The large openings at the bottom allow the concrete to flow freely, and no voids are formed. All beam saddles and separators are made up promptly upon receipt of order according to details. They are shipped crated and nested—the cheapest and best devices to accurately space and hold bars in beams and girders. The devices shown on this page have been usee for many years by leading architects, engineers and contrac- tors. and have met with universal approval.

Jam jet In Concrete Steps [19] HAVEMEYER BARS and BUILDING PRODUCTS Havemeyer Inserts for Every Purpose X N practically every factory or ware¬ house building it is necessary to hang from the ceilings shafting, motors, piping or other equipment. Inserts embedded in the concrete at the time of pouring, when properly placed, will meet any requirement. Too much attention cannot be given by the ar¬ chitect or engineer to the type of insert to be used, particularly in factory construction. Naturally, the size of the insert will depend upon the load to be carried and the type of the article which the insert is to carry. In some factory buildings, the machinery and pipe layout can be planned before the building is erected, and in such cases an ad¬ justable insert is not entirely necessary. In many cases, however, the engineer speci¬ fies an insert which will allow a certain amount of adjustability. This not only gives more leeway in placing overhead equipment, but also makes allowance for future changes. Engineers frequently will place more inserts than are necessary to use at the time a building is erected in order to provide for any changes or additions in plant equipment which might be made at some future date. It is extremely difficult and very expensive to fasten equip¬ ment to a ceiling of a concrete building where sufficient inserts are not provided. By spending a comparatively small amount of money on additional inserts, future require¬ ments can be pretty well anticipated. Have¬ meyer Inserts are provided in three general types: “Y” Socket Inserts, which are tapped and threaded, and do not allow any adjust¬ ment; Dayton Malleable Inserts, which allow adjustment up to 2"; and the Slotted Inserts, made of pressed steel, which will give almost unlimited adjustment. Havemeyer Slotted Inserts have been very popular, particularly among automobile manufacturers, and many miles have been installed in some of the larg¬ est motor car plants in the country. Safety is a most important factor in the use of inserts, as the failure of a single insert may result in serious damage and loss of life. All types of Havemeyer Inserts have been tested and will not fail. Havemeyer Slotted Inserts D avemeyer Slotted Inserts are adjust¬ able over their en¬ tire length. They are made from 15 gauge sheet steel pressed into shape and in lengths of 12", 18", 24" and 36". Where a longer ad¬ justability is required, the end caps can be removed and a continuous slot ob¬ tained. The standard type of insert uses a bolt. If a smaller bolt is desired, washers can be easily in¬ serted to hold and yy bolts. Inserts for yy bolt can be furnished on order. Havemeyer Slotted Inserts have the bolt opening in the center, so the bolt can be placed on either end. ANCHOR We would call particular attention to the method of anchorage, which is of ut¬ most importance. Steel loops are anchored below the bolt runway, which gives it the maximum carry¬ ing strength. Havemeyer Slotted Inserts are provided with six nailing holes so that they can be securely fastened to the forms while the concrete is being poured, and there is no chance of their being dis¬ placed after they are set. Havemeyer Slotted In¬ serts, using a bolt, have been tested for 12,400 lbs. We carry a complete stock of these inserts in our warehouses. [20] CONCRETE STEEL COMPANY Havemeyer Malleable Inserts AVEMEYER Malleable Inserts are made in three types: Dayton Adjustable In¬ sert No. 3, Dayton Adjustable Insert No. 5 and Havemeyer “Y” Socket Insert. These inserts are made from the highest grade malleable iron. They have been on the mar¬ ket for many years, have been thoroughly tested and always found dependable. Dayton Inserts are adjustable, as shown below, while the Havemeyer “Y” Socket Insert is threaded to receive a bolt and is not adjustable. The anchorage of the Dayton Inserts is in the form of a loop, which allows reinforcing bars to be strung through the loops if additional anchor¬ age is desired. The base surfaces of all Have¬ meyer Malleable Inserts are carefully ma¬ chined so as to fit snugly on the forms, thus preventing any possible seepage of concrete. When using Dayton Inserts it is not necessary to use washers or other devices, and accord¬ ingly bolts can be readily inserted and re¬ moved. Shipments in any quantity can be made promptly. Detailed specifications of these inserts follow. Dayton No. J Adjustable Insert Dayton No. 5 Adjustable Insert Havemeyer “Y" Socket Insert Dayton No. 3 Ad¬ justable Insert is made from the highest grade mal¬ leable iron, cast in one solid piece. Four nailing slots are provided on the outside so that it can be firmly nailed to the forms and kept in place dur¬ ing concreting. The key-hole slot not only allows adjust¬ ment of • the bolt, but also the bolt can easily be re¬ placed or removed whenever desired. This insert has been on the market for many years and has given universal satisfac¬ tion. Using a 3/i" bolt, this insert has been tested for 15,910 lbs. Carried in stock in the following sizes: The Dayton No. 5 Adjustable Insert is similar to the Day- ton No. 3 Insert, except that it is lighter and conse¬ quently designed to carry a lighter load. The an¬ chorage in the con¬ crete is not as deep. It is made from one piece of highest grade malleable iron. Both Dayton No. 3 and Dayton No. 5 Inserts when placed on the forms will not interfere with the proper placing of reinforcement, as the reinforcement can be strung through the loops if desired. Dayton No. 5 Insert, using a bolt, has been tested for 7,000 lbs. Dayton No. 5 Adjustable Inserts are carried in stock in the following sizes: Havemeyer “Y” Socket Inserts are cast in one piece from high¬ est grade malle¬ able iron. Four slots are provid¬ ed in the base for nailing firm¬ ly to the forms. The spreading anchors are em¬ bedded suffi¬ ciently deep in the concrete to give a very- strong grip. These inserts are tapped and threaded for standard machine bolts. They are frequently used in the bottom of beams, girders and slabs, where adjustment is not required, also for pip¬ ing, sprinklers, etc. Carried in stock in the following sizes: fl \ t ea 1 /uv —^ ■■■] AA/ ~\nr a .i E Bolt A B B-1 B-2 C D E Bolt A B B-1 B-2 C D E Bolt A B C D E F H" w 2H" m" iw A" 2" 14" rytt IH" 1 %" H" 2H" Vs" 2ys" IJi" ■Ue" lA" >8 2A 2A ‘iH" Vi" 2A" 2 " 1 " 2 Vs" y2” 2%" H" 1 %" iy>" 1 " 2ys" H" 2H" >yff 1 " lys" 1" '14" 3M" lA" 2A” 2 " 1 W' 2 Vs" A" 2H" %" 1 H" 1 Vr" iH" 2%" %" 2yy 2y" 1 " lA" A" 2 A >A’ “4" 4J^" ■iH" IVa" lA" 2 ^" 2%" m" VA" IH" 1 y" 2 Vs" 3" A" 'Ae" 3 Vs" 1" 2 Vi" m" IH" 2H" A" 2*54" 2W lys" lA" A’ 2A [21] HAVE MEYER BARS and BUILDING PRODUCTS Havemeyer Round Nose Curb Bar showing bending and method of bundling for shipment Havemeyer Round Nose Curb Bar AVEMEYER Round Nose Curb Bar meets every demand that a curb bar is called upon to fulfill. It is made from tire very highest grade open-hearth steel. The anchors are sheared from the web and are an integral part of the bar. These anchors are staggered and are bent out from the center line of plane, so as to secure an exceedingly strong anchorage in the concrete curb. These anchors not only hold the bar hrmly in place but also act as a preventative of cracks which frequently form in the concrete curb near the edge. The bar is rolled with a sharp edge so that no fillet is formed at this point when troweling takes place. Havemeyer Curb Bars are very simple to install. The absence of a continuous web per¬ mits even and accurate bending without kink¬ ing. The bar is so bent that the plane of the 45 degree angle is maintained in order to be in harmony with the straight bar at point of tan¬ gent. All curb bars are galvanized and shipped in bundles. Carried in stock in 8', 10' and 12' lengths. We bend to any radius.

III!.. 1 ■■ ' > Havemeyer Concrete Road Reinforcement EINFORCEMENT of concrete highways is the insurance for public good will/' Not only is this slogan literally true but it rests upon a firm foundation of practical experience and scientific fact. Our methods of transportation are now un¬ dergoing a change and many secondary elec¬ tric and steam railroads are being abandoned on account of competition from motor busses and trucks. This competition has been made possible by the widespread construction of hard surface highways during the last few years. If our concrete pavements are to carry a heavy motor bus and truck traffic, and most of them do soon after construction, they must be well reinforced with steel to insure a reason¬ able life free from excessive maintenance expense. Experience and numerous traffic tests have shown the reinforced concrete pavement to be the economic type for modern heavy traffic under average conditions. For light traffic where the structural strength of the paving slab is not so important, a moderate amount of steel reinforcement properly placed in the slab will completely eliminate cracking, reduce maintenance and insure a fine looking permanent construction. Where an asphalt or other type wearing sur¬ face is desired, a reinforced concrete base of moderate thickness will not only greatly in- Havemeyer Round Nose Curb Bar '"-'sm Havemeyer Pressed Metal Supporting Chair and Method of Holding Reinforcing Bars Havemeyer Angle Nose Curb Bar 1 [ 24 ] CONCRETE STEEL COMPANY Showing the ease with which Havemeyer Bar-Tys are locked to Road Reinforcing Bars crease the life of the wearing surface but it will prevent the formation of unsightly cracks in the pavement. All these things are accomplished at a very small proportionate increase in cost over former methods. To attain these desirable results in the most economical manner the Engineers of the Con¬ crete Steel Company have developed a system of reinforcement for highways similar in many respects to that which is now universally used in reinforced concrete building construction. More than 2,500 miles of pavements have been constructed with our reinforcement of many different types, and the durability and serviceability of these reinforced highways insures the utmost in ultimate returns for road appropriations—low upkeep costs and more general satisfaction to the public. Our engineers have inspected a great deal of this work since completion and much has been learned as a result of wide experience under varying conditions during the past five years. This data includes not only roads reinforced with Havemeyer reinforcement, but also roads in which no reinforcement was used, together with types of roads other than concrete. This information is at the service of engi¬ neers and public works officials. Write for our new Road Catalogue. Havemeyer three-eighths inch deformed self-supporting reinforcement.

Wheth¬ er you require immediate shipment or ship¬ ments over a period of time, we are in a posi¬ tion to give real service regardless of the quantity. There is today an ever-increasing demand for these products, due to the awakening of the general public to the advantages of put¬ ting up buildings either fireproof or as near fireproof as possible, and using a type of con¬ struction which will reduce maintenance cost to a minimum. Metal lath is recognized to¬ day as the most fireproof base for plastering walls, ceilings and exteriors. By using metal lath, not only is the fire risk greatly dimin¬ ished, but cracks are practically eliminated and a much more substantial structure is ob¬ tained. While the initial cost may be slightly higher than other plastering bases, the advan¬ tages gained by using metal lath more than compensate for any extra expense. We carry various types of metal lath and would be pleased to furnish architects or contractors with full information as to the type best adap¬ ted for any particular structure. It is of great advantage to the contractor to purchase all of his metal building products from one source. By so doing delays in deliv¬ ery are avoided, economy effected in delivery costs, and responsibility centralized. Some of the articles shown are carried only in our larger warehouses, as certain lo¬ calities require particular materials not gen¬ erally used.

In fireproof buildings it is used as a plas¬ tering base around steel beams, girders, col¬ umns and other structural material. With the plaster properly applied, it forms an ab¬ solute fireproofing protection for the structural members. Metal lath is also extensively used for walls, ceilings and partition work, using angles or channels as studding. A partition down to two inches thick can be made which is sound¬ proof, fireproof and of great strength. Another use for metal lath is in the fire¬ proofing of residences, garages, barns and all types of non-fireproof buildings. When used in connection with wood studding on walls and ceilings it forms, in connection with the plaster, a very valuable fire-resisting crack- proof surface. On the exterior of all types of wooden buildings, metal lath with properly applied stucco of cement will make the building fire- resisting from exterior causes and at the same time avoid expensive painting. Havemeyer Metal Lath is manufactured in various types—the type to be used on each building operation depending on the character of construction. Havemeyer Flat Lath is an expanded lath made from sheet steel, painted or galvan¬ ized, copper-bearing steel or pure iron. The openings in the mesh are of small size, thus ef¬ fecting an economy in plaster and providing a strong key. The paint used on this lath was selected after a long series of tests made under different climatic conditions in various parts of the United States and is the best preserva¬ tive that has yet been found for metal lath.

The longitudinal Ribs, or beads, inch wide, 1% inch center to center, are inter-con¬ nected at %. inch intervals by stays or strands. These strands in turn are reinforced strongly at their centers by a stiffening member. Some advantages of Havemeyer Flat Rib Lath: Permits scratching in and doubling back from same scaffold—practically two coat work —a big economy in labor and mortar. Permits wider spacing of supports—thus saving material and labor. Sheets are square-edged —no loss in lap- Ping. No jagged points to jeopardize quick handling. Alaximum economy and all the desired crackproof and fireproof qualities of ordinary metal lath. Havemeyer %" Rib Lath Havemeyer Rib Lath is very rigid and strong due to the rib expansion between the heavy Y” ribs spaced 4.8 inches on centers. This lath is used where a wider spacing of studs is desirable and economical. The lath should be placed with ribs facing the studs and at right angles to them. Havemeyer yy' Rib Lath is used economi¬ cally with Havemeyer Steel Tile and Steel Lumber. This lath is manufactured from open hearth sheets, from galvanized sheets and from rust-resisting coppered metal. Havemeyer yy' Rib Lath is easy to erect, as the outside ribs nest closely, leaving an even surface for plastering. This lath is easy to handle as there are no sharp edges or projec¬ tions. Havemeyer Galvanized yy' Rib Lath, weighing 3.6 lbs. per square yard, is a special product, and its use is recommended in place of 4.00 lb. steel lath, sold at about the same price.

[29] HAVEMEYER BARS and BUILDING PRODUCTS Havemeyer Ribplex Havemeyer Ribplex is formed from a single sheet of steel. The longitudinal ribs in height, are cold-rolled, which greatly in¬ creases the tensile strength and elastic limit. The metal between the ribs is expanded, with the strands on edge, which gives a stiff surface to work on, and is a distinct advantage over many other types. Havemeyer Ribplex has six ribs to a sheet spaced 4.8 inches center to center. Each sheet covers 24 inches in width. The standard lengths carried in stock at the mill for prompt shipment are 7, 8, 9, 10, ii and 12 feet. Havemeyer Ribplex compared with similar products, offers heavier gauge weight for weight and lower cost gauge for gauge. Havemeyer Ribplex is used largely for roof construction, partitions, floor slabs, out¬ side walls, etc. Full construction details will be gladly furnished on application.

Havemeyer Expansion Products 0 XPANSION products shown here have many very impor¬ tant advantages. These pro¬ ducts are all made from one piece of galvanized metal. The expansion portion provides a permanent bond which eliminates any possibility of cleavage and shrinkage cracks which usually occur with other types of beads and trim. Most types of metal casing provide no grip hold for the plas¬ ter, and consequently, as the plaster dries, it slips away from the metal and cleavage cracks are almost cer¬ tain to show along the lines where wall and casing meet. The tight juncture of wall and casing or bead formed by the reinforcement pro¬ vided by this expansion feature adds greatly to the sanitary conditions found in these types of expansion products. The initial cost is surprisingly low compared with the cost of wood cas¬ ings and the installation cost is muchi lower than other similar types of products. No. 6—O.G.

The small openings in the expan¬ sion wings are of peculiar advantage lending greater reinforcement and economy of plaster. These products can also be fur¬ nished in zinc and copper. By using Havemeyer No. 7 Ex¬ panded Metal Flashing, the danger of cracking of exterior stucco around doors, windows and other openings is eliminated. Water cannot leak in between casings and the stucco where Havemeyer No. 7 Expansion Flash¬ ing has been used. The solid metal wing on one side prevents this, while on the other side the expanded metal wing, with web-like bond, fastens the plaster or stucco permanently to the frame work. In both the Havemeyer Expansion Corner Bead and the Havemeyer Expansion Flashing great economies in time are effected as compared with erection under old methods. They can be wired, stapled, nailed or stuck to any kind of wall construction without the use of clips. Large stocks are carried at all warehouses ready for immediate shipment. Havemeyer No. 6, O. G.

[35] PI AVE MEYER BARS and BUILDING PRODUCTS Havemeyer Steel Tile AVEMEYER Steel Tile are light corru¬ gated steel forms used in conjunction with reinforced concrete for floor con¬ struction. Steel Tile floors eliminate useless concrete, reduce dead weight and increase live load capacity. They are cheaper on certain types of con¬ struction than wooden forms, particularly where light loads are required. They can be removed after concreting if desired. Havemeyer Steel Tile is made of No. 26, 22 and 20 gauge Steel with deep stiffening cor¬ rugations across the top and in the sloping sides. Each supporting edge is finished with a flange which prevents loss of concrete during the pouring operation. They are made in depths of 4", 6", 8", 10", 12" and 14" and in lengths of 30" and 36". Havemeyer Steel Tile are 20" wide across the bottom. They are also furnished single and double tapered, the latter tapering from 20 inches at one end to 16 inches at the other. Tapered Tile are made in 36" lengths only. It is sometimes de¬ sirable to have narrower Tile where the area to be covered is not an exact multiple of the regular 20-inch Tile. For this condition we furnish Tile in 12 and 16-inch widths in all the standard depths. These narrower widths are not supplied in single or double tapered form. There are some engineers and architects who want a deep rib corrugation. This we can furnish on order. Methods of construc¬ tion, safe loads, etc., will be the same as for standard Tile. In some cases, for the sake of economy, a greater space between the joists is desirable than is furnished by our standard 20-inch Tile. Where this condition exists we can fur¬ nish Tile 25 inches wide which will pro¬ duce joist 29 to 3034 inches on centers as com¬ pared with 24 to 2514 on centers with our standard Tile construction. Safe loads and other data on the 25-inch Havemeyer Tile for any condition will be supplied upon request. Large stocks of Havemeyer Steel Tile are carried at all branch warehouses and are shipped nested in compact bundles, easy to handle in transit or on the job. They require but small storage space and entail no losses through breakage. Where necessary, end caps can be fur¬ nished for regular or tapered Havemeyer Steel Tile.

[36] CONCRETE STEEL COMPANY Havemeyer Metal Lumber HERE are certain types of buildings where Havemeyer Metal Lumber should be used because it is econom¬ ical, practical and easy to erect. There is a decided tendency today to construct buildings as near fireproof as possible. The use of Havemeyer Metal Lumber combined with other Havemeyer fireproof products, such as Metal Lath, Corner Bead, Channels, Steel Tile, etc., are important factors in this type of construction. By the use of Havemeyer Metal Lumber lighter loads are developed, resulting in a sav¬ ing throughout the building. Lower costs for transportation and less space required for storing at site. Less labor and limited equipment required by contractor in the operation. Increases speed of construction in winter. Havemeyer Metal Lumber is made from uniform strength pressed steel. The complete joists or studs receive a heavy coat of rust re¬ sisting paint, before shipment. Havemeyer Metal Lumber is made in “Standard” and “Special” sections. Standard Metal Lumber sections are made of steel of .072 to .090 inches thick in standard designs. Metal Lumber sections made of steel .120 inches in thickness, are designated as “Spe¬ cial” and used largely for headers and trim¬ mers and in places where conditions call for increased strength. Standard Metal Lumber sections may be furnished in any desired length, subject only to shipping and erection limitation. Special sections made of metal .120 inches in thickness cannot be formed to advantage in lengths greater than 16' 8" for joists 4 to 10 inches in depth, or 12' 6" for joists 11 and 12 inches in depth.

DING PRODUCTS Havemeyer Copper Steel Basement Windows TEEL basement windows have today su¬ perseded wooden frames and sash, due to their decided advantages in dura¬ bility, neatness, lighting and ventilation, and protection of property. They unquestionably add to the house a good deal of home value as well as sales value. Steel basement windows, when made of copper steel, will last indefin¬ itely, are neat looking, both from outside and inside, and allow a greater volume of light—approximately 8o% more—based on the size of the opening, as compared with the old-fashioned wooden sash. As to the cost, they cost no more than wood¬ en sash, and in fact are cheaper, when you con¬ sider labor in fitting, installing and painting woo.den sash. Steel Sash comes all ready to set in the masonry, and no fitting is necessary. Havemeyer Basement Windows are made from highest grade copper steel. The frame is manufactured from one piece of heavy rolled copper steel. It is the stiffest frame on the market and cannot get out of alignment. Holes are provided in the frame for bolts to fasten screens. The lock is positive and safe. The lock has a cam action, drawing the ventilator tight against the frame. Muntin bars are T section, solidly riveted to frame of ventilator. Riveted jamb bar strips give a line for the mason to work to, both inside and outside the foundation. These wide bar strips provide ample anchorage and clearance for ventilator to prevent jamming against the masonry. Havemeyer Cam Section Burglar-proof Lock draws ventilator firmly against frame r ‘ —J'" 1 I ' ^_ W ^ Heavy hinges, with removable spring pins, permit easy removal of ventilators for glazing [38] CONOR E T E S 'E E E E C O M P A N \' Ventilator is hung by extra heavy hinge with spring pin offset from frame to give ample clearance. This prevents binding on ma¬ sonry, so often found in other sash. Hinge al¬ lows sash to be easily removed for glazing. Single weathering and integral drip—no rain, snow or wind can get through. Glazing clips are supplied attached to each sash in a small cloth bag. Two pounds of putty will glaze either a 1012 or 1420 window, while 22/3 pounds of putty will glaze a 1218 or 1020 window. The cost of glazing, including glass, putty and la¬ bor, for styles 1012 and 1420 is approximately 80 cents per window. This cost for styles 1218 and 1020 is approximately $1.00 per window. The rabbets that receive the glass should be bed-puttied first and the glass then set in place. The spring glazing clips are next in¬ serted, with the twisted portion of the clip em¬ bedded in the putty at the edges of the glass. (In Havemeyer Basement Windows two sets of holes are provided for inserting the clips— one for ordinary glass, the other for heavier wire glass). The glazing clips are snapped into position in the holes provided for them, by springing down the end of the clip with the putty knife. A neat finish is secured by face- puttying in the usual manner. No. 1218 and No. 1420 have been particu¬ larly designed to work out satisfactorily with concrete block, which are standardized to lay up in multiples of 16" wide and 8" high. Havemeyer Basement Windows are sup¬ plied assembled complete with glazing clips, but without glass, in the following sizes: OVERALL SIZE - 2'II W" — lO". 12- CLASS STYLE 1012 MASONRY OPENING OVERALL SIZE f- -r v> OVERALL SIZE *-j'-5 ■ 12" •18 - CLASS STYLE12J8 MASONRY OPENING 40M»‘»20V4* OVERALL SIZE 2H CLASS STYLE 14^10 MASONRY OPENING Style No. Description.

As shown in the accompanying illustra¬ tions, Havemeyer Security Anchor is nailed to the forms so that the self-contained anchor arms extend into the concrete in such a way as to secure the strongest grip. When the forms are removed, it is a sim¬ ple matter to pry between the Anchor and the wall, wherever necessary, to form loops for the insertion of Havemeyer Security Wall- Tys. These loops may be opened at any point along the strip, and the Wall-Ty can be raised or lowered several inches so as to fit accurately Qjr- NAILING HOLE between the joints of the stone or brick used on the wall. This gives a positive anchor, with the arms extending at the proper place, and forms the strongest tie between a concrete wall and facing of masonry. The Secu¬ rity Wall-Ty will not rust or become loose. Used as an anchor for sleepers, it is em¬ bedded in the surface of the concrete. Sleepers are laid crosswise and wire is inserted under the anchor and around the sleeper, thus hold¬ ing the sleeper rigidly to the concrete base. Havemeyer Security Anchor has been in extensive use all over the country and has given complete sjitisfaction in the various pur¬ poses for which it is adapted. Havemeyer Se¬ curity Anchors are specified by many leading architects and engineers. Large stocks of Security Anchor and Wall- Tys are carried at all Concrete Steel Com¬ pany warehouses, ready for immediate ship¬ ment. Samples are furnished on request.
