SUPPORT AND TIE FOR CONCRETE-REINFORCING BARS.

Specification of Letters Patent.

Patented Jan. 12, 1915.

Application filed January 12, 1914. Serial No. 811,669.

To all whom it may concern:

Be it known that 1, Greece R. SoHoEN- TI'IALER, a citizen of the United States, residing at Chicago, Illinois, have invented a and useful Improvement in Supports and Ties 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 whichvFigure 1 is a perspective view of a con crete reinforcing bar support and tie of my improved construction. Fig. 2 is a plan view of a combined support and tie of my improved construction, the same being shown in position on a pair of crossed reinforcing rods. Fig. 3 is a side elevational view of the combined support and tie applied to a pair of crossed reinforcing rods.

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

In reinforcing concrete floors, ceilings and walls, it is desirable, and in nearly all in stances, essential that the reinforcing rods be supported in a substantial manner in a plane above and 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 effectually tie the same together and 10 hold or support said rods a substantial distance above or away from the floor or form while the concrete, in plastic condition, is

being poured or distributed thereupon.

The principal object of my invention is to 5 provide a combined support and tie which can be readily applied to a pair of crossed rods, and which will not only support said rods in proper form, but will tie the same together so that both rods are effectually 9 held in proper relation to each other.

A further object of my invention is to provide a comparatively simple device in which is combined a resilient supporting leg, a U-shaped seat for one of the rods, and a pair of spring arms which overlie the upper one of a pair of crossed rods, and are detachably applied to the other rod.

y my improved construction the comblned tie and support when properly applied to a pair of crossed rods, can be moved in any direction over the form or support wlthout distorting the spring arms or causing the device to become detached or unseated from the engaged rods.

With the above and other objects in view, my invention consists in certain novel features of construction and arrangement of parts, hereinafter more fully described and claimed.

As shown in the drawings, my improved device is constructed from a single piece of resilient wire bent so that its central portion forms a short horizontally disposed base member 10 which, when the device is 1n use, rests directly upon the form or flooring. From the ends of this base member the wire is bent upward to form a pair of parallel legs 11, and from the upper ends of these legs, the wire is rebent downward to form a pair of short sections 12 which are parallel to each other and to the legs 11. From the lower portions of these sections 12 the two parts of the wire are bent so as to cross each other, as designated by 13 in substantially U-shape, thereby forming a seat for one of the reinforcing rods, and from said crossed U-shaped portions the wire extends upward parallel with the portions 12 as designated by 14:. At points beyond the rebent portions between the legs 11 and 12, the portions 14 are bent downward slightly as designated by 15 to form shoulders or seats which are adapted to engage over the upper one of the reinforcing rods to which the device is applied, and from said shoulders the end portions of the section of wire of which the device is formed extend outward in parallel arrangement to provide resilient arms 16 which terminate in crossed hooks 17 which are positioned substantially at right angles to said resilient arms.

When my improved tie and support is applied to a pair of reinforcing rods for supporting and tying the same together, the base member 10 rests upon the flooring or false work as shown in Fig. 3, and the lower one A of the reinforcing rods is positioned between the upper portions of the legs 11 and sections 12 and rests upon the seat formed by the crossed U-shaped portions 13.

A -to said rod A. Normally,

The upper reinforcing rod B is positioned upon the rod A at right angles thereto, and is arranged immediately adjacent to the rebent portions of the device between the legs 11 and sections 12. Then the resilient arms 16 are bent downward to engage the lower rod A the shoulders or seats 15 engage the upper rod B as shown in Figs. 2 and 3 and the hooks 17 on the ends of said arms 16 are engaged from opposite sides beneath the rod A at a point a substantial distance away from rod B. ported a substantial distance above the false work or flooring, and in turn said rod A supports the rod 13 and both rods are tied together by the engagement of the resilient arms over the rod B and beneath the rod A. of the arms 16 causes the hooks 17 to engage rod A with considerable pressure, thereby holding the same against longitudinal movement and likewise holding rod B against movement with respect the legs 11 support the reinforcing rods a substantial distance above the form or floor as shown in Fig. 3, but under the weight of a workman or a wheelbarrow load of concrete, said legs will yield to a certain degree and after the weight has been removed the resiliency of the legs will return the bars to their normal positions. This is a decided advantage over those forms of supports and ties which are constructed of sheet metal and the like, and which crush down under weight, thereby permitting the reinforcing rods to lie directly upon the surface of the floor or form. The base member 10 ties the lower ends of the legs 11 together and the crossed portions 13 provide a tie between the upper portions of said legs, and such construction gives great lateral rigidity to the device, and permits it to slide horizontally upon the floor or form without distorting the device or detaching it from the engaged rods.

A combined'support and tie of my improved construction is comparatively simple, can be readily and cheaply manufactured, is readily applied to reinforcing rods, and provides substantial means for tying said rods together and holding the same in proper position upon the form or false work which receives the concrete.

It will be readily understood that minor changes in the size, form and construction of the various parts of my improved support and tie may be made and substituted for those herein shown and described, without departing from the spirit of my invention, the 'scopeof which is set forth in the appended claims.

The resiliency Copies of this patent may be obtained for Thus the rod A is sup,

1. A device of the class described comprising a single piece of wire bent to receive a pair of crossed reinforcing rods and having a pair of resilient supporting legs, a pair of resilient rod engaging arms, hooks on the ends of said arms, and said arm's being correspondingly bent to form shoulders against which one of the reinforcing rods is adapted to engage.

2. A device of the class described comprising a single piece of wire bent to receive a pair of crossed reinforcing rods, and having a pair of resilient supporting legs, a base member connecting the lower ends of said resilient legs, portions of which piece of wire are bent so as to cross each other and form a seat for a reinforcing rod and the end portions of which piece of wire are extended substantially parallel with each other to form a pair of resilient rod engaging arms.

3. A device of the class described comprising a pair of resilient arms, portions of which are adapted to engage a reinforcing rod, a pair of connected legs formed of the same material of which the arms are formed, and portions of the material between said legs and arms being bent to form crossed U- shaped members which constitute a seat for a reinforcing rod.

4. A device of the class described constructed from a single piece of wire bent to form a support, and a seat for a reinforcing rod, the end portions of which piece of wire are extended to form resilient arms adapted to engage over one and beneath the other of the reinforcing rods to which the device is applied, said arms being bent to form shoulders against which the upper one of the reinforcing rods engages, and hooks on the outer ends of said resilient arms, which hooks are adapted to engage beneath the lower one of the reinforcing rods.

5. The combination with a pair of crossed concrete reinforcing rods, of a combined tie and su port comprising a single length of wire bent to form a U- haped supporting leg and a U-shaped seat adapted to receive a reinforcing rod, and a pair of parallel resilient arms, each having a rod engaging shoulder and a rod engaging hook.
