REINFORCING DEVICE FOR CONCRETE CONSTRUCTION- Specification of Letters Patent.

Patented Nov. 28, 1905.

Application filed September 29, 1904. erial No. 226,528.

To all whom, it may concern.-

Be it known that I, GEORGE L. PEABODY, a citizen ofthe United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Reinforcing Devices for Concrete Constructions, of which the following is a specification, reference being had therein to the accompanying drawings, forming part of the specification, in which Figure l is a view in side elevation of a portion of concrete construction provided with my improved reinforcing device. Fig. 2 is a plan view, on'an enlarged scale, of one end of the device. Fig. 3 is a vertical cross-sectional view on the line III III of Fig. 1. Fig. 4 is a perspective view of the portion of the bar with one of the anchoring devices attached thereto. Fig. 5 is a modified form of holdingarm. Fig. 6 illustrates in side elevation a modified construction. Fig. 7 is a plan view of Fig. 6. Fig. 8 is an end view. Fig. 9 is a detail view showing the bar pinched around the plate. Fig. 10 is a detail view showinga different form of bar. Figs, 11 and 12 show a modified construction employing a supplemental holding-clip. Fig. 13 is a detail view showing the clip detache My invention relates to improvements in devices for incorporation with concrete structuresas bridges, beams, girders, walls, ceilings, floors, columns, &c.; and it has for its object to strengthen and reinforce the concrete body portion constituting the floor, &c., embedded therein and provided with projecting arms or branches arranged at any angle desired and so constructed as to be adjusted to suit the requirements of use and to make and maintain a strong binding hold in the cement or concrete at closely-adjacent intervals.

The-invention is designed to provide a reinforcing device which will be capable of incorporation with the concrete in such a manner as to traverse the lines of probable fracture and counteract such fracture in the best possible manner, the device being provided with a closely-adjacent plurality of such arms or with arms or branches which may be adjusted to the intervals desired or required by the work in view.

Referring now to the drawings, 2 represents the main element of the device consisting of a bar of metal of any suitable cross-section, but preferably cylindrical. The bar is provided at intervals with notches or grooves 3 on opposite sides, around which are passed the looped portion 4 of the arms, which are then extended upwardly beyond the bar 2 and bent at any desired angle and looped, as at 5. The arms are made of a heavy wire or rod 6 and may be then turned backwardly, as shown in the principal figures of the drawings, and their terminal portions connected in a cross bar or clamp 7 of any suitable construction, by which the entire arm may be tightly secured in position and to the bar 2. For the purpose of insuring the gripping action of the arms upon the bar they may be abruptly bent, as at 8, thereby forming a shoulder on the upper side of bar 7 so as to prevent their loosening or removal, and as thus constructed the arms will be rigidly attached to the main bar. It will be seen that the arms may be closely assembled, as indicated in Figs. 1 and 2, and that as thus located they cross the line of fracture, as a a, at least three times, thereby providing strong counteracting reinforcing devices, which efl'ectually perform their functions. It is designed that the arms may be incorporated with the main bar at the place where used-as, for instance, in a building under construction--which feature greatly faci litates the shipment and handling of the different parts, their assemblage being a matter of simple and easy accomplishment by any mechanic.

It will be understood that any suitable device may be used for the arms, and in Figs. 6, 7, and 8 I have shown a bar 2, provided with series of abutments 9, located in oppositely-arranged series of rows with an interveningspace between the abutments for the insertion of a holding-arm of the character shown in these figures, made of a plate of sheet metal 10, having an aperture 11 for the bar and registering openings or slots 12 to facilitate its insertion upon the bar, the plate being provided with one or more upwardlybent projections 13, arranged at any suitable or desired angle, as already described.

In Fig. 9 the bar 2" is originally smooth on its exterior, the plate 10 or any other suitable branch device being provided with a corresponding aperture slipped over the bar and secured thereon by holding-lugs 14c, pinched or upset from the metal of the bar, so as to securely bind on each side of the plate and hold it in position, the plates being thus'attached at any desired interval apart.

In Fig. 10 the bar is shown as provided With lateral flanges 15 15, having notches or apertures 16 at the desired distances apart,

which engage the arms 6, as shown, the arms being tightened or fastened upon the bar in any suitable manner.

In Figs. 11 and 12 the bar is provided with the notches 3, already described, the arm extremities 6" being attached in the manner shown, and are further secured by a supplemental clip 17, consisting of a plate of sheet metal having an opening 18 for the bar and apertures 19 in its upper edge, which edge may be bent over, the clip being provided with a terminal tongue 20, which is bent up around the lower portion of the arms, as shown, thereby securely attaching it to the main bar.

All of these various devices are suitable for the objects in view and provide a main bar having rigidly-connected projecting arms capable of being bent to any desired angle and to maintain their position with relation to the bar, so as to transmit to it the various strains to which the concrete structure is subjected.

It will be understood that various other devices or constructions of holding-arms may be incorporated with the bar, and all such various changes or 1110 lilications which may be made by the skilled mechanic are to be considered as within the scope of the following claims, as I do not desire to be limited to the exact construction shown and described.

Having described my invention, what I claim isl. A reinforcing device for concrete, &c., consisting of a mainbar provided with a series of notches, and holding-arms surrounding the bar in engagement with said notches and projecting laterally from the bar, substantially as set forth.

2. A reinforcing device for concrete, 860., consisting of a main bar provided with a series of notches, holding-arms surrounding the bar in engagement with said notches and projecting laterally from the bar, with securing devices for the arms, substantially as set forth.

3. The combinationwith amain bar provided with a series of notches formed between adjacentshoulders, of holding-arms surrounding the bar and in engagement with said shoulders, and provided with apertures adapted to provide clearance therefor in assembling the.

arms with the bar, substantially as set forth.

at. The combination with a main bar provided with a series of notches, of oppositelydisposed series of holding-arn'is surrounding the bar in engagement with said notches and projecting laterally from the bar and toward each end respectively beyond its middle portion, substantially as set forth.

A reinforcing device for concrete, &c., consisting of a main bar provided with a series of notches, and holding-arms surrounding the bar in engagement with said notches and projecting upwardly and outwardly toward the ends of the bar, substantially as set forth.

In testimony whereof I afiix my signature in presence of two witnesses.
