Applieation'led April 28, 1906. Serial NDV-818.186.

To all whom it may concern.I` l

Be it known that I, AMEDE V. REYBURN, Jr., a vcitizen of the-United States, residing at the city of St. Louis in the State o1 Missourl, have invented a certain new and useful Reinorcing-Bar for` Concrete, of'which the following is such a full, clear, and exact description as will enable any one skilled in the lart to which it appertains to 4make and use the same, reference being had to the accompanying drawings, forming part ofthis specification.

My invention' relates in ore particularly to a re-inforcing bar for the construction of con* crete floors and other has for its object to which inay similar structures, and provide a strong bar be easily rolled in the ordinary be broken by the shearing strains to which such bars are subjected.

'In the drawings, in vvhich like characters of reference refer to similar parts in the different vlaterally in an Opposite views, Figure 1 is a side elevation of a bar embodying `a florm'of my invention; Fig. 2 1s a top lan view of same, and Fig. 3 is a section O a concrete fiooring in which my bar is embedded.

-Tlie bar is and' with vex lateral projections transverse to the plane of the bar. As will be seen from Fig. 1, the projections 7 8 and 9 at one edge of `the bar extend only partly across the face of the provided at each of its edges 5 bar and lie between, or, 1n other Words, are

staggered with or intermediate of, the proe jections 10, 11 and 12 at the-opposite edge of the bar.' -The projections 10, 11 and 12 also extend only bar. The direction in which these lateral rojections extend is best shown in Fig. 2. Iere the projections 7 10, 9 and 12 extend laterally to one side of the bar and the projections 8 and 11' extend laterally in the opposite direction. 1t Will4 also be noticed, reerring to the series of projections?, 8 and 9 at one edge of the bar, that the projections 7 and 9 extend laterally in an opposite direction to the projection 8. The saine isV true of the series of projections at the other edge of the bar, the projections 10 and 12 extending direction to that in which the proj ection 11 extends.

It will be observed that the projections 7 8 and 9 extend more than half way across the face of the bar. The projections 7, 8 and 9 thus'having their inner ends extend across' curved or rounded concavo-conpart Way across the face of the face of the bar beyond the line of the inner ends of the projections 10, 11 and 12; This arrangement results in leaving at portions along the edges 5 4and 6 in the plane of the bar and preserves the original strength of. the bar.

In Fig. 3 the bar is slab of concrete iioor sup orted on I-beams 15. each of t e ends of the bar is o'rtion 16 bent at 'right an es to 'themain Body of the bar and provi ed with a hook portion 17 bent over the top of the I-bearns 15. It will be seen that by iny invention I' have provided a bar of this kind which easily rolled from a suitable sheet of iron or In this case Acan be" providedwith a steel and which is provided with projections it in the concrete for locking or anchorin at they will not be block of such a nature t readily broken by the which they are subjected, and at the same time .the strength of the bar to withstand laterall and vertical strains is substantially preserved.

The ability of the bar to withstand such strains is further shearing straingto preserved by reason ofthe fact that its edges 5 and 6 substantially re-' main in two parallel lanes'after the bar has been rolled to form t e transverse or lateral prlcjections therein. I 1

aving fully'described my invention, what c aim as'new and desire .to secure by Lety ters vPatentof the Uni-ted States, is-` substantially plane of the bar intervening between indi vidual projections of the 'saine series, the
