Application filed January 29, 1923. Serial No. 615,759.

To all whom t may concern:

Be it known that I, STEPHEN L. Hniniucn,

a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Supports, of

which the following is a specification.

This invention relates to a support for use in connection with the metallic reinforcing bars or rods employed in concrete structures, that is to say, beams of concrete structures where a plurality of bars or rods are to be supported within the width of each beam, and the invention has for its object to provide asupport forsuch purpose,

in a manner as hereinafter set forth, including means for not only supporting sets of reinforcing bars or rods, but further maintaining one set in spaced relation with the other set, and at the same time act for the purpose of reinforcement.

Further objects of the invention are to provide a suppport for the purpose set forth which is simple in its construction and arrangement, formed of a single length of material, strong, durable, rigid, provided `with means to prevent the shifting ofthe bars therefrom, efficient in its use, conveniently set up in the mold, andy inexpensive to manufacture.

lVith the foregoing and other objects in view, the invention consists of the novel construction, combination and arrangementl of parts as hereinafter more specifically de-A scribed and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understoodv that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views Figure 1 is a side elevation of a support in accordance with this invention, showing the same embedded in a concrete beam and further showing the `adaptation thereof in connection with the support of two sets of reinforcing bars or rods.

Figure 2 is an end view of the support showing the adaptation thereof in connection Awith the concrete beam and reinforcing 'rods or bars.

Figure 3 is a top plan view of the supportl f Figure i is a side elevation of a modified form. v

Referring to the drawings in detail, 1 denotes the bottom of a mold structure 2, 3 a concrete beam, 4 an upper set of rein- 60 forcing bars or rods'and 5 a lower set of vreinforcing bars or rods.

As illustrated a support is shown as constructed from a single length of wire of the desired diameter and rigidity, but it is to be understood that'the support may be produced otherwise than from wire, the latter being used in the present case simply to indicate and explain the invention, but it is obvious that the support can be formed from a strip of metal which would be substantially as effective in carrying out the improvements as in the setting up of the support of wire, thus in its broadest aspects the support can be constructed of any suitable material which is found applicable.

Referring to Figures 1, 2 and V3 of the drawings, the support is constructed from a length of wire, or other suitable material, bent orv formed to provide a pair of side members each consisting of a pair of end bars 6, 7, and each having the lower terminal thereof bent outwardly at an inclination as at 8. Each of the side members further includes a bottom or base bar 9 having each terminal portion thereof bent downwardlyY and outwardly at an inclination as at 10, 11, and each of said terminal portions 10, 11, is connected by a curved coupling portion 12 to a terminal portion 8 of an end bar. The terminal portions 8, with respect to the terminal portions 10, 1'1, provide a passage 13 for the concrete and said curved portions 12 forni what may be termed corner abutments which are posi- 95 tioiied in the corners of the mold.

By setting up the bottom or base bar 9 in the manner as stated, the medial portion thereof is raised above the bottom l of the mold 2.

The inclined terminal portions 8, in connection with the curved portions 12, space the end bars 6, 7, from the mold body so that the concrete can be poured around the said side members.

The end bar 6 of a side member is of greater length than an end bar 7 and the end bar 7 of one side member is alternately disposed with respect to the end bar 7 of the other side mernber,y The upper end of an end bar 6 of one side member is connected to the upper end of the end bar 6 of the other side member by the combined coupling and supporting bar 14.

In proximity to the upper end of an end bar 6 of one side member, the upper portlon of the end bar 7 of the other side member is looped around the coupling bar 14, as indicated' at 15, and then extended upwardly as at 16 to provide a stop. By this arrangement a stop 16 is positioned at each terminus of the coupling bar 14.

The raised portion of the bottom or base bar 9 of each side member provides a` support for the lower series Vof reinforcing rods or bars 5. Thecoupling bar 14v forms a support for the upper series of reinforcing rods or bars 4.

The side members of each of the supports are disposed at an inclination and extend in opposite directions with respect to each other and when the support is mounted in the mold 2, it rests upon the bottom 1, and with the reinforcing rods or bars 5 extending through the side members and seated on the base or bottom bars 9 and with the reinforcing rods or bars 4 seated on the coupling bars 14. When the reinforcing rods or bars 4, 5, are positioned with respect to the support, in a manner as shown in Figure 1, the stops 16 prevent thebars 4 from shifting off the support and the end bars 6, 7, of the side membersy act as means to prevent the bars 5 from shifting out of the support.

Hold-fast devices 17, as shown in Figure 2, may be employed to fixedly secure the supports in the mold 2 so that they will be prevented from shifting during the pouring of the concrete.

ln the modified form shown in Figure 4, the construction is the same as that referred to in connection with Figures 1, 2 and 3, with this exception that the coupling bar which is indicated at 18, is offset to provide a plurality of seats 19 for the reinforcing rods or bars 4, and the bottom or base bar of each side member which is indicated-at 20 is offset to provide a plurality of seats 21 for the reinforcing rods or bars 5.

Each of the side members which are termed supporting elements, issubstantially rectangular in contour and of skeleton formation and the end bars of said side members are connected in such a manner with 'respect to the coupling bars 14, that the stops 16-will be on oppositeA side of said coupling bar 14.

Fromthe foregoing description taken in connection with the accompanying drawings, an economical construction of' support for a plurality of reinforcing barsis set up, such aswould be required in the beam members of concrete structures and at the same time the support actsas a webrinforcement, and

although the preferred embodiment of the invention is as shown, yet it is to be understood that changes in the details of construction can be had without departing from the spirit of the invention as claimed.

That l claim is rM 1. A support for the purpose set forth comprising a pair of supporting elements, a coupling bar connecting the upper portions of said elements together, and each of said elements extended around said coupling bar to provide a vertically disposed stop, and each of said elements being substantially rectangular in contour and having each lower corner thereof extended outwardly at an inclination and with its base positioned above said extended corners.

2. A support for the purpose set forth comprising a pair of skeleton supporting members each including a pair of end bars and a base bar, the lower terminal portion of each end bar extending outwardly and the terminal portions of said base bar extended at an outward inclination and merging into the extended portions of the end bars, a coupling bar connecting the upper portions of said elements together and each of said elements looped around and extended above said coupling bar, the portions of said elements extended above said coupling bar constituting stops, and said coupling bar and base bar of said, elements providing supports for reinforcing rods or bars in concrete structures.

3. A device for the purpose set forth comprising a pair of skeleton supporting members extending in opposite directions with respect to each other and each including apair of end bars and a base bar having a port-ion thereof positioned above the lower termini of the end bars, a coupling member connecting one of the end bars` of one element to one of the end bars of t-he other element, and the other end bars of said elements looped around and extended above the coupling bar to provide stops.

4. A device for the purpose set forth comprising a pair of supporting elements of skeleton formation and each includinga pair of end bars and a base bar, a coupling bar connecting one of the end barsl of one element to one of the end bars of therother element, and the other end bars of said elements looped around and extended above in a vertical direction from said coupling bar and providing stops.

5. A device for the purpose set forth comprising a pairA of supporting elements. of skeleton formation and each including a pair of; end bars anda base bar, a coupling. bar connecting oneA of the end bars of one element to one of. the end bars of other element, and the other end bars of said` elements looped around and extendedabove in a vertical direction from said coupling bar and providing stops, said stops positioned at the ends of said coupling bar and and on opposite sides of the latter.

6. A device for the purpose set forth comprising a pair of supporting, elements of skeleton formation and each including a pair of end bars 'and a base bar, a coupling bar connecting one of the end bars of one element to one of the end bars of the other element, and the other end bars of said ele ments looped around and extended above in a vertical direction from said coupling bar and providing stops, the base bar of each of said elements having the end terminals thereof extended downwardly and outwardly at an inclination and the lower terminal portion of each of the end bars of each element extended outwardly at an inclination and spaced from and connected with an inclined terminal portion of a base bar.

In testimony whereof, I afix my signature hereto.
