SUPPORT AND 'IIE FOR.CONCRETE-REINFORCING BARS.

Specification of Letters Patent. Patented Jan. 29, 1918.

Application filed June 28, 1915. Serial No. 36,666.

' To all whom it may concern.-

Be it known that I, GEORGE R. SCHOEN- THALER, a citizen of the United States, residing at Chicago, Illinois, have lnvented a certain new 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.

My invention relates generally to reinforced concrete construction and more particularly to a combined chair and clip which is adapted to serve as a support and a tie for the metal bars used in reinforced concrete structures, such as floors, roofs, ceilings, walls and the like, and my present 1nvention is an improvement on the form of chair and clip shown and described 1n my copending application filed 'November'18, 191 Serial No. 872,752.

It will be understood that where metal bars or rods are utilized for reinforcing concrete construction, it is essential that said bars be tied together and supported a. suitable-distance above or away from the surface of the form or mold in orderthat when the concrete is poured sald reinforcing rods or bars will be embedded in the concrete-the required depth to properly reinforce it.

The principal object of my invention is to provide a comparatively simple, cheap and efiicient chair or support and tie which can be readily combined with a single reinforcing bar or with two bars which are crossed and arranged substantially at right angles to each other, and which combined support and tie when properly applied for use ties the crossed bars to each other in a firm and substantial manner and maintains them in proper position while the concrete .is being poured over and around said bars.

Further objects of my invention are to combine with a practically rigid support or chair, a tie, preferably in the form of a ductile wire, and which latter is permanently secured to the support atthe time the device is manufactured.

V In my present device, the tie wire being ductile to a considerable degree, can easily and quickly be bent upward from the sup- I '55 port or chair into engagement w th the supported-bars and the ends of sa1d wire can be readily twisted together so as to firmly tie the bars together at the crossing points and at the same time firmly securing said support to said bars.

With the foregoing and other objects in View, my invention consists in certain novel features of construction and arrangement of parts hereinafter more fully described, claimed and illustrated in the accompanying drawings, in which-.

Figure 1 is a plan view of the blank sect1on of sheet metal from which my improved chair or support is formed and showing the .tie wire attached thereto.

F ig. 2 is a. perspective view of a combined chair-and clip of my lmproved construction,

the same being applied to a pair of crossed reinforcing bars.

Fig. 3 is an end elevational View of a combined support and clip.

Fig. 4 is side elevational view of the combined support and clip.

B 1g. 5 is a side elevational view of amodified form of the support and clip.

ig. 6 is a plan View of the blank section of sheet metal fromwhich the modified form of the device is constructed.

Fig. 7 1s a plan view of a further modified form of the device;

Fig. 8 is a side elevational view of the form illustrated in Fig. 7;

Fig. 9 is a perspective view of a further modified form of my improved support and clip.

Fig. 10 is a plan view of the blank section of sheet metal which is utilized in the construction of the form of clip illustrated in Fig.9.

In the form of device illustrated in Figs. 1 to 4 inclusive the support or chair is constructed of a substantially rectangular, oblong, section of sheet metal, the same being bent at a centrally arranged transversely disposed line to form an inverted V-shaped body, the same comprising inclinedlegs 10, the lower ends of which are adapted to rest upon the false work or form which serves as a temporarysupport for the reinforced concrete construction. The lower ends of these inclined legs 10 are provided with upwardly projecting notches 11 which permit the semi-plastic concrete to flow. freely into menses In so far as I am aware, I am the first to produce a combined support and tie for concrete' reinforcing bars which involves a sheet metal base or support and a ductile tie wire permanently secured thereto, and practically forming an integral part thereof.

A device of this character can be economically produced, can be readily applied to reinforcingbars and by virtue of the ductility of the tying member, the same can be brought into close engagement with the supported bars, thereby tying the same together in an efiective manner.

It will be readily understood that minor changes in the size, form and construction of the various parts of my improved device can be made and substituted for those herein shown and described, Without departing from the spirit of my invention, the scope of which is set forth in the appended claims.

I claim:

l. A reinforcement supporting device comprising a supporting member in the form of a ductile sheet metal blank shaped and bent to provide angularly disposed members and a loop across the line of bend therebetween, and a ductile tie member retained by said loop and secured therein by the metal drawn on the line of bend in the shaping of the supporting member.

2. A device of the class described comprising a supporting member consisting of a ductile sheet metal blank cut and bent to provide angularly disposed membersand a loop-adjacent the line of bend therebetween,

and a ductile tie member retained in said loop and secured therein by metal drawn at the line of bend in the shaping of the supporting member.

3; An article of the class described comprising a supporting member consisting of a blank of ductile sheet metal cut and bent to provide angularly disposed members and a on the line of bend in the shaping of the supporting member.

4. An article of the class described comprising a supporting member consisting of a blank of ductile sheet metal having a portion thereof slotted and shaped to form a loop,a ductile tie member disposed in said loop, and the supportingmember being bent to form angularly disposed portions and distorted portions at the line of bend therebetween, which latter engage the tie member to bind it in the loop.

5. A device of the class described com-' prising a ductile. sheet metal supporting member slotted to form a loop, a ductile tie member disposed in said loop, portions of the supporting member being bent relative to eachother to provide angularly disposed portions, and a portion of the metal intermediate said portions being distorted to bind the tie member in the loop.

6. An article of the class described comprising a supporting member of ,ductile sheet metal having deflected portions bent intoangular relationship, a portion'of said member being slotted to form a loop extending across the line of bend and having its ends integral with the deflected portions respectively, and a ductile tie member disposed in said loop and retained on the supporting member by clamping cooperation of the loop and adjacent portion of the supporting member In testimony whereof I hereunto afiix my signature, in the presence of two witnesses, this 24th day of June, 1915.
