wclear, andexact description of the same, reference being'had to the accompanying drawlugs, and to the letters of reference marked thereon, which forma part of this specifica tion.

In the construction of reinforced or armored concrete a great variety of so-called Systems or arrangements" of the metal relatively the concrete investing the same have been'devis'ed,"in all of which some means are necessary for rigidly connecting (at least ten 1- .orarily) thevarious metallic members formmg the skeleton or tension members of the structure; 4

in many ofthe'so-called systems metallic bars or rods havebeen so disposed that when invested with theconcrete' said rod-s or bars if in a horizontal slab orbeam lie well below the neutr'alaxis. of'the structure, and in such constructions 'resortfhas been had to various devices to properly space themembers in the bottom of the beam. Sometimes blocks of concrete or cement have'been molded and placed beneath the main tension membersto support the same at a suf licient height above the form to insurethe same being entirely invested with the concrete and to afford a sufficient body of concrete below the same to af- 1 ford-therequisite adhesion, due to the surface adhesion of the concrete upon the steel. 1

Usuallyin connecting transverse and longitudinal members wiring has been resorted to. "this; however, is a comparatively slow process and in the event ofupwardlydirec ted' *strapsas' for instance inbeam construction, the upwardly vdirected ends of the straps possible, to hold' the same at the'desiredpo are free to be readily movedand-inconsequenc'e it has been very difficult, if not imsition or angle to insure the most effective re-v suits .on thev completed structure, as forfinstance-when using: such upwardly direeted arms or. straps a's shear members. p

s 'Ihe'object ofthis invention is to afford an assembling clip adapt'edtorigidly lock intersecting structural members at the point of intersection to'hold the samerigidly in place while the investment of concrete orcerne'nt .peing applied thereto.

by assembling clips Itv is also an object of the invention to afford an assembling clip adapted to rigidly en gage together, upwardly directed U straps or bars, in such manner as to rigidly support the arms thereof in the'adjusted position.

Furthermore, it is a very important objectv of the invention to afford an assembling clip adapted also to serve as a s acing member or foot piece by the use of whic the tension-rods are all supported at the best practicable.

height above the bottom of the form to insure the greatest strength in the construction when completed, said supporting portions of said clip being so constructed, however," as to permit the same to be invested with concrete or'cement and to permit the concrete to bond thoroughly around the joint at the intersection.

It is finally an important object'of the invention to afford a construction of such cheapness and practicability as to insure its extensive use and of such simplicity as toenable any unskilled laborer to instantly apply the same in place to secure the maximum holding efiectthreof.

The invention consists in the matters hereinafter described and more fully pointed out and defined in the appended claims.

In the drawings: Figure 1 is a fragmentary perspective. view illustrating the applic a tion and useof clips embodying my invention. Figs-2 is an enlarged. central section taken longitudinally of the transverse reinforcing memben. Big. 3 is'asection taken on line 38 of Fig. 2. Fig. lfis an enlarged top plan view of the assembling clip. Fig. 5 IS a section on line 5-5 of Fig. .4.

As shown in thedrawings: AAf Andi-- .cate longitudinal. tension members such as.

may be employed in the construction of beams and various other/armored concrete constructions.

.U strap having lugs or arms I), directed wardly, asis usual inthe arrangement of other purposes. All'said members, as shown, are constructed of. round steel rods whlch shbar members for beams; and for many 10-5.- a of course, be of any desired diameter an at their. lntersectlons with each other said elements}.-ere' rigidlyengaged, together tion. SaidichpJ-asshown, is co tructed preferably of a sheetjor plate of big carbon steel e e u ab e meatsi ated embodying my-invem' .ini'ts plane to a U shape and affording divergent ends a, in the rounded top of which are inwardly struck projections or-teeth c, which may be of any desired number and arrangement. As shown, however, one of said inwardly directed integral teeth is provided in the top and near each end 'of the clip on approximately a medial lineland directed oppositely and asshown, two are shown centrally and on opposite sides of. a

' medial line in the top of said clip with the abrupt faces thereof directed inwardly as indicated in Fig. 5. The divergent ends of. each of said-clips are notched at the bottom to afford forwardly-and rearwardly arranged downwardly directed legs 0 -0 adapted to rest on'the bottom of the form.v Opening.

through corresponding sides of each of said armsO', of the clip is a notch rounded at its inner. part and inclining. slightly outwardly and downwardly as shown inFig. 2, and having sharp edges adapted to engage and bite into the lower pr tension rods'A, when. en,

'gaged yin clamping transverse members thereto. Said notch in width vertically is made somewhat larger than the rod to be engaged therein and the bottom of. said 1 pressure being sufiicient to permit said notch is'at' a distance from the top of the clip to permit of firmly jamming the rods togeth'e gas shown in Fig; 1, when the clip is engaged into place. v

Y The operation isas follows: In engaging the members together the clip-is straddled over the upper or transverse bar with the notchdirected in position to receive the longitudinal member therein and the divergent ends or arms of the-cli are sprung together, as shown in dotted lines -in Fig. 3, thus slightly inc'reasing the distance of the-bottom of the notch in said arms from the top of the clip .in which position the cli may be .slidon the trans-versejmember u'nti the tension member at right anglestherewith lies within the notch as indicated in Figs. 2 and 3.

Preferably, the construction is such as to necessitate a. slight pressure in springing the a clip into place and when the lower or divergent ends of the clip are released the same springoutwardly as shown in full lines in Fig. 3, the outer edges at the bottom Of.

thenotch en aging-the tension rod A and pressing the same upwardly carrying the transverse rod a or strap B therewitlnthe sharp edges to bite slightly into the rod and to force the transverse member firmly against the inwardly directed teeth c'in the top of for the longitudinalro' positively supported'either vertically or in any desired inclined position, while the concrete or cement is being packed, about the.

same, and inasmuch as the legs 0 0 which, as shown, are of small size and extend some distancebelow' the longitudinal rods or tension members, the entireskeleton thus-formed is supported a suflicient distance from the form to .insure the correct. position of the arm .within the investing material.

While'I have in my specification referred to tension members. and shear members,

I'of course, do'notpurpose limiting the application-of-devices embodying this invention to such specific uses, -for evidently, any

intersecting rods for whatsoever purpose used, or affording whatsoever portion of the interior metallic structure for armored concrete, may be engaged together by means off said clips. 'Of course too, it is' not essential that the rods engaged together should be of the same size for the clips may, of course, be.

constructedto engage a Fsmaller'upon a larger rod or vice versa,'or when constructed as shown in Figs. 2'and 3, with each notch for the tension rod of'greater width than the diameter of the rod, the ,rodsmay'be proportionately varied in dia meterto any extent, providedthe sum of the diameters'of the rods be approximately the sum of the diameters of the rodsof equal sizewhich the clip c0 uld engage together.

Obviously therefore, I do not I urpose limiting thisapplication forpat'ent 0t erwise thanneccs'sitated' by the prior artas details of construction and application ,may be varied without departing of this invention.
