CHICAGO, ILLINOIS, A CORPORATION OF DELAWARE.

n13 CHAIR.

Application filed December 26, 1922. Serial No. 608,863.

To all whom,- it may concern:

Be it known that I, WILLIAM E. WHITE, a citizen of the United States, and resident of Chicago, in'the county of Cook and State of Illinois, have invented certain new and useful Improvements in a Rib Chair, of which the following is a specification.

My invention relates to devices for supportin concrete reinforcements and particulai ly to a novel rib chair of simple and economical construction. I a

One of the objects of my invention is to provide a supporting device of the character described which shall be ofutmost simplicity. To that end I construct the device from a single length of wire and so design the chair that it may be formed by automatic machinery. This results in extremely low cost. I

A fundamental feature in the design submitted is in that I provide two A frames which furnish the required stability and i join them by a member shaped to provide seats for reinforcing bars and located at the required height whichwill be at a point intermediate the height of the A frames. In addition I provide means for spacing the chairs relative-to the sides of the forms which outline the lateral limits of the rib.

The invention will be more readily under--.

stood by reference to the accompanying drawing, wherein Figure 1 is a perspective view of a rib chair constructed in accordance with my invention;

Figure 2 is an end view thereof;

Figure 3 is a perspective view of a modified form of the'device;

Figure 4 is an end view thereof;

Figure 5 is a perspective View of a further modification; and

'Figure 6 is an end viewthereof.

In the drawings,'referring particularly to Figures 1 and 2, it will be seen that in constructing the device of mv invention I utilize a single continuous length of wire of suitable size. and stiffness and form therein two V-shaped structures 10, 11, the legs 12, 13, of each of which rest upon a form' and stabilize the structure. The wire at the termination of the legs 12 is re-bent and pro jects upwardly and longitudinally away point 15 the wire is again re-bent, thc portions 16 extending horizontally. The point 15 is so arranged as to constitute spacing means for the chair whereby to suitably center the chair and consequently the reinforcing bars within the rib. Intermediate the ends of the horizontal portion 16 I provide a loop 17 which may project upwardly or diagonally upwardly as shown. This results in the formation of pockets 18 for the accommodation of the reinforcing bars.

In the construction shown in Figures 3 and 4, the elements remain the same. How ever, the legs 19, 20, occupy different vertical planes, being spaced apart by means'of a horizontal member 21.- Thus the leg 2() acts as the means for centering the chair in the form. In this instance the re-bent portion 22 lies in the same plane with the leg 19.

The horizontal part 23 and the loop 21 are neath the apex of the A frame and this lends stability to the structure.

In the construction shown in Figures 5 and 6, the legs 25, 26, are arranged the same as in Figure 1, being in the same plane.

Likewise the part 27 is upwardly and l0n-.v

gitudina'lly outwardly bent, the end 28 constituting the spacing device for the chair. However, the portion 27 is bent outwardly from the terminal point of the leg 25 instead of inwardly as in Figure 1. Thus the horizontal part 29 and the loop 30 which constitute the seat for the reinforcing bar are located outside of, insteadof inside of the legs as in the two preceding figures.

In each of the structures described it will be noted that the same structural features are present and that the device is of such sim-' 'plicity that it may beformed economically.

By employing wire ofsuitable gauge and stiffness the required strength and stability are secured.

Obviously the construction is capable of l some modification and I do not wish to be limited except as indicated in the appended claims. i i

I claim: 1. A ribchair composed of a-continuous wire bent to provide two pairs of spacedapart legs, each pair beingarranged in V- shape, a connect g'membr located intermediate the height of the legs and providing a seat .for a reinforcing bar, and, laterally projectingmeans for spacing the chair in a form. v

2 A rib chair composed of a continuous wire providing two pairs of legs and a connectin member, said connecting member being arranged-horizontally at a point midof two of said legs and means in the con-' necting member for providing a seat for a reinforcing bar 4. A chair consisting of a continuous length'ofwire bent to provide two pairs of legs, each pair of legs being arranged in V-' shape, and a connecting member extending between the pairs of legs and formed by rebending the Wire upwardly'from the ends of two of said legs, means in the connecting member forproviding-a seat for a reinforcing bar, and laterally projecting means for spacing the chair in a form.

Signed at Chicago, Illinois, this 20th day of December, 1922. 1
