HIGH CHAIR FOR CONCRETE REENFORCING SYSTEMS Filed Feb. 24, 1930 "was a Strain sine VfIlLLTAll l T. BAUIJIAIT, F GHIOAGO, ILLINOTS, ASSIGNOR 'TO UNIVERSAL FORM CLAMP 00., 6F CHICAGO, ILLINOIS, A. CGRPGRATIOII OF ILLINOIS HIGH-CHAIR FOR REENFORCING SYSTEMS Application filed February 24, 1930. Serial No. 430,956.

. The main objects of this invention are to provide an improved bar support and spacer for use in reenforcing systems of concrete construction work; and to provide an improved high-chair for reenforcing bars wherein sections of identical construction are secured together to form the complete support and spacer, thereby reducing its cost and facilitating its manufacture and assem- 10 bly.

An illustrative embodiment of this invention is shown in the accompanying drawings, wherein:

chair.

The common types of bar supports and spacers heretofore in use generally included two or more separately formed members of different shapes which were welded 01, otherwise secured together. It was, therefore, necessary for the manufacturer to carry in stock a large supply of each part of the units.

In the construction herein shown, the improved high-chair comprises two sections of substantially identical size and shape which are rigidly secured together to form the com- I chair comprises a pair of substantially identical sections 3, which are rigidly secured together.

Each of the sections 3 comprises a wire which is bent to form a horizontal shelf l,

legs

6 and 7, respectively. The shelf el, arm 5 and leg 7 of each section are preferably located in a single plane, from which the leg 6 diverges downwardly.

When the sections areassembled, they are arranged as shown in Fig. 1, with the shelves :1, arms 5 and legs 7 of bothsections located in substantially a single vertical plane and ,the legs 6 diverging downwardly on respectively opposite sides of that plane. The shelves 1 are preferably spot welded together, as shown at 8, and together with the arms-5 they form a substantially U-shaped saddle for supporting the r'eenforcing bar. The legs 7 of the assembled. unit preferably diverge downwardly from each other.

The high-chairs embodying these improvements are exceedingly simple inconstruction and operation, comparatively inexpen-o s'ive to manufacture, and up.

I claim:

1. A bar support comprising a substantially U-shap-ed wire saddle having a horizontal base part and a pair of upstanding arms, the upper ends of said arms being bent downwardly to provide a' pair of end legs, and a pair of intermediate legs on respectively opposite ends of said base part, said intermediate legs diverging downwardvery rigid when set 1y on respectively opposite sides of the plane of said saddle.

2. A bar support comprising a substantially U-shaped wire saddle having a horizontal base part and a pair of upstanding arms, the upper ends of said arms being bent downwardly to provide a pair of end legs, said end legs and saddle being disposed in substantially a single plane, and a pair of intermediate legs on respectively oppoe site ends of said base part, said intermediate legs diverging downwardly on respectively opposite sides of the plane of said saddle.

3. A. bar support comprising a substantially U-shaped wire saddle having a horizontal base part and a pair of upstanding arms, the upper ends of said arms being bent downwardly to provide a pair of end legs, said end legs diverging downwardly from each other within the plane of said saddle, and a pair of intermediate legs on respectively opposite ends of said base part, said intermediate legs being located on respectively opposite sides of the plane of said saddle and diverging downwardly therefrom.

4. A bar support comprising apair of connected wire sections of substantially identical construction, each of said sections comprising an L-shaped portion having both of its ends bent downwardly to provide a pair of depending legs the L-shaped portions of both sections being united to form a U-shaped saddle for supporting a reenforcing bar.

5. A bar support comprising a pair of connected wire sections of substantially identical construction, each of said sections comprising an L-shaped portion having both of its ends bent downwardly to provide a pair of depending legs, the L-shaped portions of both sections being united at their bases to form a U-shaped saddle for supporting a reen'forcing bar one leg of each section being disposed in the plane of said saddle, the other leg of each section diverging downwardly from said plane.
