. In. carryingout myinvention', I employ a U or V-shaped device or retainer made pref-- erably of a springy orresi-lientimaterial havi. ing a recess or recesses slightly largerthan the rod or rods emploved, which latter-pass through the deviceand are located or locked in said'recesses, sothat when-said rods arematerial of which the-- device isycomposed For the purpose of illustrating my inven tion, I have shown in the accompanying drawin one form thereof'which isiat pres-.
ent pre erred by me, sin'celthesame has been found in practice to give satisfactory and reliable results, although it is to be understood that the variouslinstrumentalities of whichmy invention consists can bevariously' arranged and organized and that my invention is not limited to the precise arrangement and organization ofithese' instrumentalities as herein shown and described.
Figure 1 represents a perspective view ofa device for positioning reinforcing rods embodying my invention. Fig. 2 represents an end view of-Fig. 1. Fig. 3 represents'a side view of Fig. 2. Fig. 4 represents a erspec tive view of another embodiment o *my invention, wherein two pairs of rods are shown which is paratory to applying the cement .or concrete STAYMENTOFFICE ffaten ted June 3, 1913.111
thereto. Fig. '5' represents an end view of 4. Fig, Grepresents a side elevationof Ij\1.-5. I p 4 v imllar numerals of reference indicate corresponding parts in. the figures.
Referring to-the drawings 1 designates my, novel device' for positionin reinforcin rods, the sanie consisting ;of a fmembe'ror stirrup havlng -the. whereby said rods "are readily arrangedend- I or V shap rounded,nas indicated at v ,"fidesignates the upper reinforcingrod in assembled position with respect to the device -lftil'ld z' designates the lower reinforcing rod extending, in the present instance, transversely thereto,"i t beingapparent that when thei rqds}G and; 7 are assembled, the resil i=' en'cy of tl-ie membersflcauses the-lower rod side portions 2, which-are joined by the portion 3, which. maybe flat, curved or V-shaped, thesa-id; side portions or walls 2 each .a recess lQ thGI BlIl, the inner terminal" of preferably slightly enlarged or 5, saidrecess simu ,latin'ga.keyhole slot.
having therein 7; to press-or bear [on theupper rod 6-,; them terminals 5. of theflrecesses 4 being preferably of such fareathattheatop edge or portion of the lower. rod-7 contacts'with the bottom 7 portion of2'the upper 1 rod 6, while the latterwill cause the lower-rod or rods to press or will be-rcau'sed to bear or press against the underside of the top my invention as" applied to a retaineror device 8-, wherein the lower portion of the walls 9 preferablydiverge outwardly and attheir; upper portion meet'thepreferably sub-' ly 'parallel walls 10,
curved; In place of'the each wall, as seen in Fi' 1, 2 and 3, Pen ploy an upper recess 1 ,whose inner terwhich are" oined" by the portion .11, which maybe flat, be'n't'orsingle recess 4 in;
minals 13 are preferably curved or'widened,
while below the 1'ecesses12are the substanti'ally parallel or similarrece'sses 14:, whose inner portions or. terminals are curved or widened, as indicated at 15. 'When the rods.
16, 17, 18 and 19 are assembled, as will be understood-,from Figs. 4 to 6, inclusive, it will be seen" that by reason of the construc tion of the recesses 12 and 14 and the arrangement of the, enlarged portions 13 and 15 thereof respectively, thelower'rod 19 will bear against the-bottom portion of the rod the latter contacting with the under side of the portion 11, whereby all the rods will be arranged and retained in their proper relative position, and will be kept up out of contact with the form or mold so that the rods and their retainer 8 will be completely embedded in the cement or concrete when the finished structure is completed.
It will be apparent that I may employ as many of the devices 1 or 8 as may be necessary, and-that said devices 1 or 8 may be constructed out of any suitable resilient or springy material, which will have the effect of keeping the contacting edges of the assembled rods in the desired position preparatory to applying the cement or concrete thereto, and. when the structure is completed by the application of concrete thereto, the rods and the positioning device 1 or 8 will be completely embedded and sealed within the concrete.
It will be apparent that without departing from the spirit of my invention, I may make the device 1 or 8 of V shape or more nearly U-shaped, but in practice, I prefer to have the lower portion of the members 2 or 9 sli htly flare outwardly'or diverge, substantially as shown, but I do not desire to be limitedto the precise construction I have shown in every instance, as it will be apparent thatvarious modifications may be made by those skilled in the art, which will come within the scope of my invention.
It will now be apparent that I have de vised a novel and useful construction of a device for ositioning rods in concrete structure, whic embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in the present instance, shown and described a preferred embodiment thereof which has been found in practice to give satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various particulars without departing from the spirit 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 a 1. As an improved article of manufacture, a device for positioning. reinforcing rods comprising a plurality of walls joined together by a looped portion, each wall having a recess therein terminating in an enlarged opening, in combination with a rod of rectangular cross section traversingsaid openings and having a diagonal dimension greater than the width of said recess, a second rod, between said looped portion and said first rod and having a diagonal dimension substantially equal to the distance between a corner of said first rod and said looped portion whereby said second rod is locked inoperative position by wedging action created by a partial rotation of said first rod.
2.

4. As an improved article of manufacture, a device for positioning reinforcing rods comprising a U-shaped member having outwardly flaring lower'terminals, a plurality of recesses 12 and 14 in each of said walls extending inwardly from the edges of said wall and terminatin in an enlarged 0 ening, polygonal rein orcing rods 17 and 19 arrange in parallel relation and respectively traversing said openings,- said rods having a diagonal dimenslon greater than the width of the respective recess, a polygonal' reinforcing rod 18 straddled by said device andhaving a diagonal dimension substentially equal to the distance between juxteposed corners of said rods 17 and 19, and a polygonal rod 16 above said rod 17- and straddled by said device, said rod 16 having a diagonal dimension substantially equal to the distance between a corner of the rod .17
and said U-shaped member and said rods 17 and 19 being adapted to be partially roteted into engagement respectively with said rods ,16 and 18, whereby all of said 10 rods are locked in operative position by a wedging action created by the diagonal p0- sitioning of said rods 17 and 19.
