SUPPORT AND TIE FOR CONGRETE-REINFORCING BARS.

Specification of letters Patent.

Patented June 15, 1915.

Application filed March 25, 1914. Serial No. 827,118.

To all whom it may concern Be it known that I, GEORGE R. SoHoEN- of the United States, residing at Chicago, Illinois, have invented a certain new and useful Improvement in Supports and Iies for Concrete-Reinforcing Bars, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings,

forming part of this specification, in

which Figure 1 is a perspective view of a combined concrete reinforcing bar support and tie of my improved construction. Fig. 2 is a side elevational view of the support and tie positioned for use on a pair of horizontally disposed crossed reinforcing rods. Fig. 3 is a side elevational view of the combined support and tie, the same being adapt- 7 ed for use in connection'with vertically disposed reinforcing rods, as are used in walls and partitions. Fig. 4 is a perspective View of a key utilized in connection with the support and tie when the same is applied to vertically disposed reinforcing rods.

My invention relates generally to reinforced concrete construction and more particularly to a support and tie for the metal rods used in reinforcing concrete floors, ceilings, walls and the like. 7

In reinforcing concrete floors, ceilings and walls, it is desirable and in nearly all instances, essential that the reinforcing rods be supported in a plane above or away from the temporary flooring or form upon which the concrete is laid, and to this end, I have devised a comparatively simple, strong and inexpensive support and tie which is formed from a single piece of resilient wire and which can be readily combined with reinforcing rods so as to maintain the same a substantial distance above or away from the cor or form while the concrete in plastic condition is being poured or distributed thereupon. I

The principal object of my invention is to provide a combined support and tie which can be applied to a pair of intersecting rods, and which will yieldingly support said rods, and at the same time'tie the same together so that they will be held in proper form while the concrete is poured or distributed upon the form for the floor or wall.

A further object of my invention is to provide'a comparatively simple device in which is combined a pair of supporting legs, a pair of horizontally alined seats for one of the reinforcing rods, and apair of resilient arms which can be readily bent downward over a transverse fulcrum, which latter is a part of the combined support and tie, thus imparting to said arms sufficient resiliency so that the same firmly engage and grip one of the reinforcing rods, thereby holding the same against longitudinal movement and at the same time effectually tying the crossed rods to each other and the device to said rods.

With the above and other objects in View, my invention consists in certain novel fea tures of construction and arrangement of parts, hereinafter more fully described and claimed. 7

As shown in the drawings, my improved device is constructed from a single piece of resilient wire, the central portion of which is bent so as to form a short horizontally disposed member 10, which when the device is in use, is positioned across the top of the upper one of a pair of crossed reinforcing rods. From the ends of this centrally arranged transverse member 10 the wire extends laterally and downwardly as designated by 11, thence upwardly and outwardly as designated by, 12, and from the upper ends of these portions 12, the wire is bent downwardly as designated by 13 into a plane lying parallel with the plane occupied by the portions 12. From the lower ends of the portions 13 the wire is bent upwardly as designated by 1 1, thence downwardly as designated by 15, and thence upwardly and laterally as designated by 16. The portions 14 lie parallel with and immediately against the portions 13, thereby forming a pair of legs A, the lower ends of which are adapted to rest on the floor or form when the device is in use. The portions 15 lie parallel with and immediately against the portions 12, and the portions 16 lie parallel with and immediately against the portions 11. Between the lower ends of the parallel portions 11 and 16 and 12 and 15 are formed curved seats B which are in horizontal alinementwith each other, and 'which recelve the lower one of the i crossed reinforcing rods. The portions 16 overlie the ends of the central transverse member 10 and from said member the endportions ofthe section of wire; of which the device is formed extend outwardly and upwardly as designated by 17, thereby forming resilient arms, the outer ends of which terminetein transversely disposed-hooks 18.

hen my improved support and tie is used in connection with horizontally d1sposed reinforcing. reds the lower ends of the I legs A rest upon the flooror form as seen in.

Fig. 2. The lower reinforcing rod X is .positidnedfupon the seats the upper reinforc ng rod Z rests upon said lowerrod X and passes between the upper portions of V the-parall 1 sections 11 and 16. The transand such increased verse member 10 rt ontop of the upper rod Z, and the springarms 17 which nor-,

Normally, the legs A support the reinforcing rods as shown in Fig. 2, e whee barrow'load of concrete, said legs will yieldi to a certain degree, and after this weight has been removed the resiliency of the lugswillj return the bars to their normal positions. N This is a decided advantage over'those forms of supports and ties which are constructed offsheet' metal'and the like, f down under weight, thereand which crush by permitting the reinforcing rods to lie directly; upon the surfaces of the fleoror form.

Where the device is intended for use in connection with reinforcing rods in' walls and 'the like, the legs A are made slightly V circular seats longer in the other form of the device, and'thus the outer ends of said legs extend beyond the upper or outer one of, the reinforcing ro ds. "This forms a pair of semi- S at the lower ends of the legs A and 'nserted through these seats is a wedge or key 19 preferably formed of sheet metal and which, when driven in firmly, ties the device to the reinforcing rods.

Ordinarily the spring arms 17 are sufficient to clamp the device to the bars, and this wedge is only an additional precaution to hold the parts in proper shape when crete is dumped from an unusual height, and there is tendency to jar the bars loose from one another and from the tie.
