Patented July 7, 1931 WILLIAM E. WHITE, or CHICAGO, ILLINOIS BAR an Application filed December 10, 1927. Serial No. 239,077.

My invention relates to concrete reinforc ing devices and particularly to an improvement on the bar holding clip illustrated in my ,copending application, Serial 7 5,113,

filed December 12, 1925, patent No. 1,677,066

of July 10, 1928.

An object of the construction disclosed in my said copending application is to provide self acting means for holding a bar in 10 proper relation to a chair or spacer; that is, means that will operate automatically "to grasp the reinforcing bar without the need for manual operation such as the twisting or bending of a wire around the bar. This object is attained in the said construction, but due to the fact that the holding capacity is wholly frictional, there is a tendency for the bars to escape from the clip after having been placed therein. This is objectionable and has resulted in the construction disclosed herein.

The general features of the present construction are similar in that the device provides for the insertion of the bar between a pair of resilient arms. However, the holding means for the bar are positive in the present instance, as distinguished from frictional. Such means comprise a pair of hooks constituting the terminals of the arms,

said hooks projecting inwardly and lying in substantially the same plane. The construction is such that after the bar has been inserted between the arms, it cannot be removed except by actual distortion of the hooks. While the bar is' securely held against escape, it is notwithstanding permitted longitudinal movement which is quite essential during the process of installation.

The invention will be more readily understood by reference to the accompanying drawings, in which Fig. l is an elevation showing my improved bar holding device, the bars being shown in section;

Fig. 2 is a plan view thereof;

Fig. 3 is an elevation of the clips in closed or initial position, and

Fig. 4 is a side view of the construction shown in Fig. 2.

In the drawings, I have shown the clip as applied to a combined chair and spacer, consisting of a length of wire having straight connecting portions 10, and looped portions 11, constituting a chair. At each chair I provide the clip or bar holder of my invention. It comprises a length of wire having a loop 152 that underlies the chair, the side members of the loop being twisted or otherwise secured to the straight portions 10 of the wire by bending the same therearound as at 13. The free ends it of the length of wire extend diagonally upward and toward each other and their terminal portions are rebent to form hooks 15, which in their initial positions lie adjacent to each other, and in the same plane, as indicated in the drawings.

A bar may be inserted in the space between the arms by placing the same in the V shaped notch 16, above the hooks and pressing downward. This causes the arms to separate and after the bar passes the hooks, the arms will spring inwardly toward each other and lie in the position shown in Fig. 2. hen in that position, the bar cannot be removed without destroying the hooks on the arms. In can, however, be moved longitudinally as required for adjustment.

The form of the spacer and chair is not essential and the exact angle and position of the arms and hooks may be Varied within limits, all without departure from the spirit of my invention.

I claim:

1. The combination with a spacer, of a bar holder applied thereto, said holder comprising a pair of independent, upwardly projecting, resilient arms, the free ends of 'u' the arms being in the form of inwardly projecting hooks, the ends of the hooks being adapted to he immediately above the bar at such angle that the bar cannot escape without distorting the hooks.

2. The combination with a spacer, of a bar holder applied thereto, said holder C0111 prising a pair of independent, upwardly projecting, resilient arms, the free ends or" the arms being in the form of inwardly pro- I jecting hooks that lie in substantially the same plane the ends of the hooks being adapted to lie immediately above the bar at such angle that the bar cannot escape with out distorting the hooks.

3. In combination, a spacer and a bar clip, said clip being composed of a single length of wire intermediate portions of which are bent around the spacer to secure the clip in position, the ends ofthe wire projecting upwardly in the form of arms, the terminal portions being rebent toward each other to' overlie the space between the arms and to prevent the removal of a bar.

signature.

In testimony whereof I have aifixed my WILLIAM E. WHITE.
