' BAR, CHAIR.

Application iied'riine i, 1926. Serial N70. 113,661.

My invention relatesto appliances for. use'm connectlon with concrete reinforcement, and particularly to a combined chair and holder for reinforcing bars.

'5 An object in the design here disclosed'fis to provide a rigid and stable chair, together with means incorporated therein for securing a bar thereto.

The construction is such that when the parts are assembled with a bar in place, the

bar serves as a stabilizer for-the chair; in

other words, the bar functions as the abutment or stop, preventing separation of the legs of the chair. This unusual result is secured by pivoting one leg of the chair'to the rigidly united pair of legs, providing the pivoted leg with a pocket and adapting the leg to be swung past the center of the other legs, so that when a bar is in place, the bar is pinched or grasped between the leg elements. The result is a combined chair and fastener that eliminates the usual tie element, and is extremely firm, rigid and'stab'le.

The invention will be more readily understood by reference to the accompanying drawing, in which the'figure numbered 1 is a perspective View of a chairconstructed in accordance with my invention, a short section of a reinforcing bar being shown in position, and with the side form omitted.

Figure 2 is an end view thereof;

Fig. 3 is a plan view thereof.

In the drawing, it will be seen that a reinforcing bar is indicated at A, it being intended that the bar shall be supported a suitable distance above the base. i

The support and holder consists of two sections of wire, bent and assembled to' form a stable tripod. One part carries two legs joined by means of the loop, 12. As shown, the legs, 10, converge to their junction with the parallel loop arms, 12. The feet, 11, are formed as shown in order to provide arelatively large area for contact with the soil.

The second part consists of a leg, 13, having a downwardly and laterally bent end portion, 14, adapted to underlie a side form in dicated at B and be securely held against tipping. The arrangement also functions to accurately space the chair or support relative to the side form. At the upper end of the leg, 13, the wire is rebent as at 15, to form a pocket adapted to receive the bar, A. At the extremity of the upper end, a closed 10, each having feet, 11, the legs, being hook, 16, is provided, adapted to engage the upper end of the loop, 12.

It will be noted that the two legs and their attached feet, 11, project diagonally to'one side of a longitudinal vertical plane passing through the bar A, and that the leg, 13 projects diagonally 'on the oppositeside, thus forming a stable structure, furthermore, that *the' fastening element insures rigid holding engagement with'the bar under all circumstances. The method of application is very simple. The hooked portion, 15 is engaged with the bar, the part carrying the legs, 10, beingfirst swung into a vertical position away from the open side of the hook. Thereafter, the twin legs, 10 are swung downwardly and inwardly past the vertical'line through the center of the bar into the position shown in the drawing. The foot, 14, isthen projected beneath the form. When in this position, no force applied vertically will be sufficient to disengage the fastening, any such force tending to insure a tighter grip on the bar. The construction presents many advantages in manufacturing, shipment and install-ation. It adapts itself to effective nesting, and there are no loose tie wires to become entangled.

The form illustrated is intended for use in concrete roads, but other forms and dimensions of the parts may easily be made to adapt it for general reinforcement. While thedevice is shown in cooperation with a side form, it is thus used only when employed to support the outside bar. When used in other positions, it will function Wholly as a support and fastener, the spacing function not being utilized. Changes such as indicated are considered to be within the spirit of my invention.

I claim: I

1. In a chair, the combination of a section of wire bent to provide a pair of diverging legs, the middle port-ion of the section of wire being in the form of a loop, and a second section of wire pivoted to the loop in the first section, and rebent to provide a hook, said second section being adapted to be positioned to act as a brace or third leg and to confine a bar in the hook thereof.

2. In a chair, the combination of a pair of aligned diverging rigidly connected legs, a second leg or brace pivoted at the junction of the pair of legs, said brace being bent to provide a bar pocket whereby a bar may be confined within the pocket, the otherwise open side of the pocket being closed bythe upper portion of the pair of legs.

3. In combination,

v the form of a tripod, two of said legs being rigidly joined and the third leg being pivoted to swing in a plane intersecting the plane of the said twolegs, the third leg having an open sided recess at a point near its pivot said recess being closed :by the upper portions of said two legs when the maining legs, said pivoted leghaving a rethree legs arranged in bent portion forming, a hook adjacent to pair of legs rigidly joined and providing a pivot attheir junction, and a third leg mounted on said pair of legs at said pivot point, said third leghaving an open sided recess adapted to receive va bar, the open side of said recess being closed by the upper end of one of said pair of legs when the three'legs are in tripod position. a

In testimony whereof I have vaii'ixedmy signature.

WILLIAM El WHITE.
