I have shown one form of my improved road.

chair used in assembling an upper series of intersecting reeniorcmg rodsA and B and a lower series of intersecting reenforcing rods My improved road chair is formed from a single continuous piece of heavy wire and comprises a single lower upright portion 20, an intermediate ofiset portion 2l and a second upright portion 22 bent atits fupperf'encl to provide a loop '23 overlying the upper 'rod Aof the upper series,'a transverse loop '24 underlying the lower rod'B ofthe upper se-,

ries andan end'projection 25 also overlying therodA. 7

- The lower end of theupright portionis bent to provide a horizontal loop 26 and at the free end of the loopthe wire isinclined upwardly: and outwardly as indicated at 27 and is providedwith an offset endportion or hook 28 adapted to overly the lower rod -B of the lower series. 1.

The chairs are assembled as indicated in Fig. 1, with the lower'rod B of the lowerseries resting on the ofi'set portion 21, the upper rod A of the lower series supported on the rod B, the-lower rod B of the upper series supported in the loop 24 and theupper rod A of. the upper series resting on the rod B and held from-upward displacement by the loop 23 and end portion 25. i

The offset lower'end portion 28 overlies the lower rod B of the lower series and prevents clockwise angular movement of the chair relative to the rods B and B as viewed in Fig. 3. The offset .end'28 also assists in holdingthe rod B in position At the same time the loop 24 underlying the lower rod B of the upper series and the loop 23 and end portion overlying the. upper rod A of the upper series prevent anti-clockwise swinging movement of the chair relative to the rods movements in either direction.

B and Bf and also prevent lateraltwisting.

and they definitely space and position the two series of rods relative to each other and to a supporting surface, the loops 26 forming substantial and extended footings for the road chairs.

In order to retain the transverse rod A of the lower series in position on the longitudinal rod B, I provide the retaining clip 30 shown in detail in Figs. 4, 5 and 6. The clip 30 comprises a piece of wire extended at right angles to the upper. rod to be secured and provided with an offset portion or hook 31 at its end adapted to hook under the lower rod of the pair to which the clip is applied. The wire 30 is offset upwardly at 32 to overlie'the rod A and is then doubled and bent downwardly to provide a U-shaped loop 33,

y the extreme lower portion of which is bent forward in the form of a U-shaped projection 34. This projection 34 is preferably curved to closely engage the offset portion of the chair.

The short side of the loop 33 is curved and bent forwardly, as indicated at 35. substantially parallel to the portion 30. The down-.

wardly bent portions 33 converge, as indicated in Fig. 6, and are so spaced that the rod B will be engaged and held against the lower side of the rod .A andsubstantiallv above the projection 34. I.

When in use, the retaining clip is applied as indicated in Fig. 1. with the projection 34 underlying and gripping the offset portion 21 of the road chair. The clip -is therefore effective not only to secure the rods A and B together. but also to secure the lower pair of rods to the oifset portion 21 and thus prevent upward displacement of the rods. 'The clip also secures the rods to the upright portion 22 and prevents lateral displacement.

My improved road chair and cl-ip'are both formed from a minimum amount of material'to accomplish the designated purposes and they provide rigid and substantial support for an upper and lower series of reenforcing' rods as already fully described. The various rods are so firmly secured together that a mat formed of rods secured by my improved chairs and clips may be lifted and transported as a unit from the assembling rack-to the road position in which it is tobe used without collapsing or folding inany direction. V

v While I have shown the free end of the loop 26 extended upwardly at 27 and offset at 28 to overlie the lower rod B and thus prevent rocking of the chair clockwise, I may accomplish the same purpose by extending the upper end 25 of the chair as indicated at 37 in Fig. 10 and providing an offset portion or hook"38 adapted to underlie the up perrod B. The extension 37 and-hook accomplish exactly the same'purpose as the extension 27 and offset or hook 28 and likewise prevent clockwise rocking of the chair.

It will be understood that the construction indicated in Fig. 10 may be substituted for the construction shown in 27 and 28 in Fig. 2 or for similar constructions in the forms shown in Figs. 7, 8 and 9, and it will be further understood that the parts 37' and, 38 may if desired be used in addition to the complete construction shown in the other figures, as indicated at the right in Fig. 1.

In Fig. 7 I have shown a form of road chair which in general closely resembles the form previously described but in which the offset 41 between the upright portions 40 and 42 is in line with the lower rod B and is inthe plane of the upper loop A3.

This construction may be used where it is desirable that the parallel rods A and A form the extreme upper and lower members of the assembly and the parallel rods B and B form the intermediate members. The tie clip 30 is the same as previously described and serves the same purpose, exceptthat the end 31 thereof is hooked under the rod A instead of under the rod B as in the previous construction.

In the construction shown in Fig. 8, an offset depending loop 51 is formed between the upright portions 50 and 52 and the foot portion 56 is preferably (but not necessarily) exthis construction, a standard form of retain ing clip 58 may be used by merely increasing its width. 7

'In Fig. 9, I have shown a modification of the construction shown in Fig. 8, in which the extended loop or foot portion 56 is omitted and the inclined portion 59 is connected directly to the lower end of the portion 50. This somewhat simplifies the manufacture of the chair but correspondingly reduces the footing of the chair in: contact with the road bed or other supporting surface. This con struction may be substituted in the other forms also.

In all forms of the invention, the offset intermediate portion is preferably curved downwardly to form a recess to more effectively retain the r'eenforcing rod supported thereon.

All forms of my invention firmly support both'the upper and lower series of reenforcing rods in such a manner that the assembled structure cannot be canted or collapsed by swinging movement of the chairs. The two series of rods are also supported and secured in such a way that they are definitely spaced limited to the details herein disclosed, other wise than as set forth in the claims, but what I claim is 1. road chair formed from a single continuous piece of wire andcomprismg a single upright member oifset: at an intermediate' upright member offset at an intermediate point to provide a support for, a lower pair of reenforcing rods and reversely bent and doubled at its upper end to position and support a second pair of reenforcing rods, one end of said upright member being extended laterally to engage one of said reenforcing rods at a point substantially spaced from said upright member, thereby preventing rocking movement of said road chair relative to said rods in one direction.

3. A road chair formed from a single continuous piece'of wire and comprising a single upright member offset at an intermediate polnt to provide a support for a lower pair of reenforclng rods and reversely bent and doubled at its upper end to position and sup-.
