' t l, llamen A. lWnnMonn, l titanes, residing in `a, =`ennsylvania, have invented wiroveinents in Supporting and cans 'for llicinforcing-Bars, of

`Iowing is a specilication.

yntion relates to reinforced conare incre fully set 'forth here ence being had to the accomy awings, in which: ,u i, is a view in elevation of one ot spacing device einl'iodying my 1nand. Fig. f2, is a lperspect-ive view o'j desirable, in 'the use ot reinforcing :n concrete construction, to support and the at substantially definite and intervals in order that full advaninay be taken, of the amount of reinforcinatnial-used, and in order further that no excess ot nieal. and that trie concrete shall be reinforced to saine improved structure l preferably bars at definitely spaced points; the i organized when assembled ln other instances the i ipporting; means may be ad I el" 'to each other, it. desired, ,-,.i that changes if the position or width of iaration beti en the rods niay be accom- L-lacing the saine on the job, i ierally, however, itA is prethat the4 supporting and spacing ne definitely placed.

and having substantially the shape of the letter Wl or an inverted W in cross section, with a plurality oi legs 5 for engagement with the centering; the legs 5 being connected by a web 6 below the bar l. The legs as well as the walls of the web G are apertured at 7 for the passage of the bar l. lt will be understood, of course, that the upsetting of 'the bar l as indicated at a is accomplished after the chairs haveu been strung upon the same.

lt may be desirable to take advantage of the springy nature ot this chair to maintain the same substantially -at any point along 'the rod; the upper portions above the bar l having a tendency to grip the reinforcing rod supported by the saine. l prefer, however, to upset the metal ot the bar 1 to hold the chairs in position and definitely space the saine. This is substantially a necessity, since the supporting,y and spacing means are Vhandled roughly; being generally thrown upon the job, and the chairs must maintain their place upon the rods l. l do not wish, however, to be limited to this construction.

The chair forming' the subject of my invention is particularly sturdy, since its shape and the provision of more than two supporting legs renders it still' and practically non?A collapsible, even by the weight ot workmen walking over the same before the concrete is poured. i

l rlhe combination of a bar, a supporting chair carried by said bar, said chair having a plurality of legis formed by folding the metal upon itself into lift-shape, all of which legs are apertured for the passage 0l the bar, said legs being` disposed diagonally with respect'to each other and frictionally held to the .bar in adjusted. positions'by the inherent resiliency thereof, in combination of the metal will tend to f1ic`tiona11y clamp In testimony Whereoi` I have signed my Vche chair to the bar, in combination with rename to this speeienton.
