Be' it'known thatV we, CHARLES D.

songe resident of BenvAvon, in the county of Allegheny and State of Pennsylvania,.

and ALBERT W York, county of New,York, and State of New York, have invented a new and useful Improvement in 'Reinforced Concrete Gonstruction and we do hereby declare the fo1- lowing to-be a full, clear, andv exact description thereof.

vOurinvention, relates to reinforced concrete construction. -7 The-.main 'object of our invention is to providea'-reinforcing bar of such cross sec'- tionasftofg'ivethe maximum strength while at the-.saune time capable of being so formed' aste-provide for interlocking said bar with a ltension vbar extending at right angles thereto, or forming a mechanical bondv with the-concrete surrounding the same.

L A' further object of our invention is to provide a bar 'of this character provided `with means in itself for supporting saidjaar on the centering or making provision for the attachment thereto of tlocr or ceiling strips. To these ends our invention comprises the novelv features hereinafterV set forth and claimed.' 1

1u the accompanying-,drawings Figure 1 is a plan view `of al'portion' of a lmetallic fabric used for concrete construction embodyin our invention; Fig. 2 is a section on the Igino 2-2 Fig. 1; Fig. 3 is an enlarged section on. the line 3 3 Fig. 1; Fig. 4 is a.

crosssection on the line 4 4- Fig. 1 Fig. 5

apperspective view of a portion of our re# hiforcedbar; Figs. 6, 7 8 9 and 11 are modified forms of our invention; Fig. 10 is a cross section on the line 10-10 Fig. 9, and

Figu12 is a cross section on the line 12-12 Fi l1. y i f the drawings the numeral 2 designates a bar which may-be rolled vin suitable rolls,

said bar consisting of the'enlarged or thickbody portion 3 with the flanges 4 proectingout therefrom. The Vflanges 4 maybe slit-or cut at' -jintervals to form the loops 5 and"'where said bar is used 1n connection with cross 'tension members 6 sa1d tension ,members7 which may be of the same cross Btl-EL, a resident ofk New round bar 17 passing through thelop 5.

be bent overthe. loops so as'fto forman inter-locking connectionat the' points -where support the bars' upon the centering while" the concrete yis being tam-pcd around the' i' fabric, the straps 1() may be cut in the lianges ltand said straps aref'then turned down into the position indicated-in Figs. 3 and 4. The fasteners 11 secure the 'straps to the centering 1 2. In this manner provisionv 1s made for firmly usupporting the fabric so that it is held in proper position when the concrete is tampedin place. In addition the straps 13 may be formed in vthe flanges of the bars, said straps 'extending through the concrete 14tandforming a support for the ceillng strips 12a which are often desirable in this/.class of work. 0r, if desired, the strips 15 as indicated in Fig. 7' may extend up through the cement and may he'attached to the strips 16 to which the flooring 16 may be secured In Fig. 6 we have illustrated a-modied form of 'tension bar which consists of the Again, in Fig. 7 we have illustrated sti another modilied form of my invention in which instead of forming v`a loop in the flanges, the strap 18 is formed which is adapted to be bent up to almost entirely inclose the square tension member 19.

In Figs. 8 and 9 we have shown a modied form of our invention in which the bar 2O has its flanges 21 corrugatedpse that when the bar is surrounded' with concrete these corrugations will act as a mechanical bond between the bar and the concrete and make a very strong and rigid construction.

In Figs. 11 andv 12 We have illustrated another form of our invention in which the 2.- In reinforced concrete construction, the combination of a bar, loops formed in said bar', a tension bar passing through said loops, said last named bar having straps formed therein adapted to engage said first named bar.

3. In reinforced concrete construction, the combination of a bar having an enlargedor thickened body portion with flanges projecting therefrom, loops formed in said fiunzes, a tension-bnr of like cross section passing` through said loops, said'last named bur having straps formed in its Ranges adhpted to engage' said first named bar.

4. In reinforced concrete construction, the combination of a bar having an enlarged or CHARLES D. WA'rsoN. ALBERT W. BUEL.
