Application filed May 25, 192?.

My invention relates to a new and useful installing device for placing reenforcing in concrete, and more particularly to a supporting and spacing device whereby the reenforcing wire mesh or bar mat may be supported in position with respect to the road bed while the concrete is being poured, to insure uniform level and proper spacing of the reenforcing material. I

My invention further relates to an in stalling device whereby a plurality of vertically spaced layers or lines of reenforcing wire mesh, or thelike, may be supported in a mold or form while the concrete is poured,

one layer of reenforcing wire mesh being near the bottom and one near the top of such mold, as may be desired.

To the above ends, my invention consists of a yoke or transverse supporting beam adapted to be supported by the upper edges of the walls of a mold or form into which concrete is to be poured, a plurality of pendant arms or hooks rigidly secured to said yoke at suitable intervals, said pendant arms being provided with vertically spaced and horizontally projecting lugs adapted to engage and support the transverse wires or bars of a reenforcing wire mesh or bar mat, locking pins adapted to engage the apertures n said lugs, and a handle on the end of said yoke whereby the same may be revolved or turned to withdraw said pendant arms from engagement with the reenforcing wire mesh after the concrete has been poured.

My invention further consists in the novel features and details of construction illustrated in the accompanying drawings and de scribed in the annexed specification.

For the purpose of illustrating my inven tion, I have shown, in the accompanying drawings, a form thereof which is at present preferred by me since it wlll give, in practice, satisfactory and reliable results, although it is to be understood that the va rious instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as hereinshown and described.

In the accompanying drawings:

Fig. 1 represents a top plan view of the installing device embodying my invention.

Serial No. 193,995.

2 represents a side elevation of the same, certain parts being shown in section.

Fig. 3 represents an end view on line 33 of Fig. 2.

Fig. 4 represents a reenforcing mat of steel bars or wire mesh.

Fig. 5 represents a view on'li'ne 5-5 Fig. 2.

Referring to the drawings, in which like reference characters indicate like parts, 1 designates the road bed or sub-grade of a street or the like, on the sides of which are positioned the suitably spaced construction walls or mold sections 2 between which the concrete is to be poured and which support the transversely disposed supporting beam or yoke 3, from which depend the supporting arms or hooks 4, rigidly secured thereto by the bolts or rivets 5. 6 and 6 designate upper and lower horizontally projecting apertured lugs or hooks which are adapted to support the transverse wires 7 of the reenforcing mat of bars or wire mesh 8 or the like, shown in Fig. 4. YA locking pin 9, having the upper handle 10, is adapted to be inserted through the vertically aligning apertures 11 in said lugs 6 and 6 to prevent displacement of the transverse wires, 7 of the wire mesh 8 with respect to said lugs, thereby to maintain the wire mesh 8 in position while the concrete is being poured in the mold. A handle 12 is rigidly secured to either or both ends of the yoke or beam 3 by means of the bolts or rivets 13, whereby said yoke may be turned or revolved to withdraw the pendant arms from engagement with the wire mesh 8 after the concrete has been poured.

The beam or yoke 3 is further provided with the pendant supporting arms 15, rigidly secured thereto by the bolts or rivets 5, and having the outwardly projecting lugs 16 and 17 which support the transverse wires 7 of the wire mesh 8 or the like, in the manner shown in Figs. 1, 2 and 5, the purpose of said arms 15 being merely to support the body of the wire mesh 8 against sagging until the concrete has been poured, two or three arms 4t having lock ing pins 9 coacting therewith being sufficient to prevent the displacement of the wire mesh 8, although it is to be understood that the number of arms 1- and 15, as well as the number and character of the lugs 6 and 6 and 16 and17 may be varied to suit varying requirements, the particular number and character of such arms and lugs shown in the drawings being merely illustrative of the invention.

Thus, for instance, when it is desired to build a concrete road having, say, a double line or layer of reenforcing wire mesh, that is, one layer of reenforcing wire mesh near the bottom, and one near the to 3 thereof, the subper and lower apertured lugs 6 and 6 and the lugs 16 and 17, of the pendant arms or hooks 4 and 15 respectively, with the locking pins 9 passing through the apertures 11 in the lugs 6 6 to prevent the displacement of said wire mesh. After the concrete has been poured to the desired height, the locking pins 9 are Withdrawn from their engaging position, and the beam 3 is turned or revolved in the direction of the arrows 14, by the handle 12, through an angle of 90 degrees, so that said handle 12 and said arms 4 and 15 occupy the position shown dotted in Fig. 3. In this posiv tion, the arms 4 and 15 are withdrawn from engagement with the wire mesh 8 which is now suspended in the concrete. To permit of the withdrawal of the arms 4 and 15 from engagement with the wire mesh 8 in the manner just described, after the concrete has been poured, the arms 4 and 15 are made shorter. than the distance between any two successive wires of the reenforcing wire mesh. The beam or yoke 3 is then'advanced or moved to new position and revolved in the reverse direction so that the arms 4 and 15 are again in the. position shown in Figs. 1 and 2, and the operation is again repeated.

WVhile in the foregoing description and in the accompanying drawings, I have disclosed pendant arms or hooks 4 and 15 having two vertically spaced outwardly projecting lugs for the support of two corresponding, vertically spaced, layers of wire mesh or the like, it is to be understood that it is within the scope of my invention to vary the number of said arms and lugs to suit varying requirements, the particular arrangement shown and described being merely for the purpose of illustration.

It will thus be apparent that I have devised a new and useful installing device for placing reenforcing in concrete, which embodies the.

features of advantage enumerated as desirable n the statement of the invention and the above descriptlon and while I have, in the accompanying specification shown and described a preferred embodiment thereof, it is usceptible of modification in various particulars without departing from the spirt or scope of the invention, or sacrificing any of its advantages.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1.
