In 'usmgfthese unit g rders theforms are located at -aicertain dlstance apart and the, unit girder is laced therein.

On the top of each of these gir ers orthe shear members, I la the-netting D, which consists of longitudina rodsd and transverse rods d, which-are preferably welded together at their places of intersection (1 to form the netting,

In the attached to-the shear member by passing the rods E underneath the vertical rods'b of the shear member and overthe rods d ofthe netting, asshown in Figs. 4 and 5 ofthe drawing, these rods E securely fastening the netting to the unit bar, or rather, to the shear members thereof, it being understood that' the proper form of framework is constructed and the concrete F is placed therein to make such a construction, as shown in Fig. 4, when the form is remove'deoutside of the shear member.

In Fig. 3 I have shown a slight modification of the side member A. This construction which I have marked A consists of an eye beam, the upper .flange of which is cut away at theends from the webafand bent up to form the upper inclined portion a of said member. r

In the construction shown in Figs. 1 to 5 and Fig. 7 of. the drawings, I have placed the inclined portion a or a of the side members Itis to be understood that I am not confined to this arrangement, and in Fig. 6 I have shown a construction in which the inclined portions (1 of said member are so arranged that they lie inside the' vertical rods or bars I), forming the shear member. I) are turned around the rod (1 in such a manner that the end thereof will rest against the inner surface of the web (fi'iust ead of'the outer surface, as shown in the prior figures of the drawing. 1

Instead of-bending the free ends of the stirrups around the lower bars of the side members, I mayconnect the stirrups to. theside members by securing the free ends of thestirrups directly to the web of said side members, as shown by Fig. 7 of the drawing. The stirrups m'a'ybe secured to the web by electric welding, riveting or-in any othersuitable' manner; 7 In Fig. 7 I' have also showna modified construction-of centering device. As there shown, ;tlie-':center1ng (lGVlC'G consists of a number of lates C of met-al, secured tothe flanges .of'jt e' side members; of th'ese -platesissplit and'one leg C' ;of each is tended downwardlytoifonn the bottom ('L'l The lower ends of these rods tering -de'v ice,;- the other leg (Xof each departing from the spirit. of theinventiom.

, to theends'of theb plate is extended laterally to; form the other.

centering member.

I'nsom'e cases it may be advisable to bring the stirrups and the upper bent portions o the side members in contact,"as shown'in Figs. (3 and 7, andthese stirru smay besecured to the side portions of tIie'side members by electric welding or otherwise, at.

places of 'contact,'z.- This is an especially desirable form for the reasonthat,'1n conjunction with the uniting of the other parts of the structure already described, it joins the en-- tire structure into one unitary whole, so that strains on any part thereof is transmitted to other parts, throughout the whole. The arrangement of the netting outside of the side members, shown in Fig. 6, also has peculiar advantages but this is not claimed as it is better developed in the structure shown, and

is claimed, in m oopending application No.

382,155, filed Ju y 5, 1907..

In Fig. 8 I have shown a modifiediconstruction of, the side members.- In. this construction I have used two rods a and a arranged vertically overeach other. The end of the up rrod is bent on an incline, as

shown in ig. lot the drawing. Instead of connecting 'these rods together hya web I may connect them together by 'aseries. of. I

clips F securedto the rods at their unbent'or' parallel port-ions.

In Fig. 9 I have shown a side member formed with the rods a and a." parallel throughout and the series of clips extending ars..

' It is understood that "in the l constructions shown in Figs. 8 and 9 the cli s are spaced it predetermined distance, andt ieyare'soc'onstructed thatthebars u', a are separated. one lying over the other.

From thefore'goingdescription the advantages of the invention will be readily understood. While I have shown certain forms of construction, it is to be understood that many' changes fnmy be made. therein and? many a )parently widely difl'eren t embodiments o the invention may be made without or matter-reluting to 0.1- hl-nring uponth e scope oflheinven't-ion. which, asa'matter of language, might be said to l'all tlrerebetween.v

for attaching the same to each other.

A reinforcement for concrete construction, comprising two side members each formed of a pair of longitudinal rods or bars one over the other, the ends of the upper rods being bent or upturned, the unbent portions being connected to the lower rods, a series of stirrups consisting of bent vertical rods or arms, the free ends of which are extended around and secured to the lower rods of the sidemembers, and a series of longitudinal connecting rods or arms fixedly united to the stirrups at the places of intersection, and centering devices, one of which is adapted to rest 'upon the bottom. of the mold and the other tion, comprising two side members, eachformed of a pair of longitudinal rods or bars one of the same lying in a plane over the other, the ends of the upper rods being bent or upturned, and a network composed of a connected series of rods or arms bent into arch form between the side members and suitably secured to the lower rods of the pair, said network having its elements fixedly united with each other at their places of intersection, and said network being fixedly united to the upturned ends of the upper rods of the side nembers.
