G. N. WILSON. RBINPORGING BAR. APPLIUATION rum JULY a. 1907.

` WlT/VESSES TTOHNE YS GEORGE NEAL WILSON, OF PHILADELPHIA, PENNSYLVANIA.

REINFORCING-B AR.

specification of Letters Patent.

Patented June 9, 1908.

Application filed July 8, 1907. Serial No. 382,595.

To all whom 'it may concern:

Be it known that I, GEORGE N. WILSON, a citizen of the United States, and a resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and Improved Reinforcing-Bar, of which the following is a full, clear, and exact description.

My invention relates to metallic bars used in concrete work and more particularly to a form of bar offering certain advantages relative to its anchorage in the concrete.

Reference is to be had' to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the iigures.

Figure 1 is a fragmentary perspective showing a bar made in accordance with my invention, and provided with the various bends and other portions of different conformity for enabling the bar to be embedded within the concrete; Fig. 2 is a reduced side elevation of the same; Fi l. 3 is a central horizontal section upon the line 3 3 of Fig. 2, looking in the direction of the arrows, and show ing the foot or bottom web of the bar and its various bends; Fig. 4 is an enlarged section upon the line 4-4 of Fig. 2, vlooking in the ,tom with a flat web or foot 8.

direction of the arrows; and Fig. 5 1s an enlar ed section upon the line 5--5 of Fig. 2, loo 'ng in the d1rection of the arrows.

A central web portion 6 is provided at its top with a lflat web or head 7 and at its bot- At various portions of its length the web 6 is connected lntegrally by means of thickened portions 9 with the head 7 and foot 8. This head is provided with portions 10 bent downwardly and these portions are alternated with other ortions 11 bent upwardly. The foot 8 is similarly provided with comparatively thin portions 12 bent downwardly, these portions being. alternated with other thin portions 13 bent upwardly. When' this bar is embedded in concrete it will be noted that the various bent portions 10, 11, 12, 13 afford excellent anchorages within the concrete and also that these portions prevent longitudinal displacement of the bar. Not only this, but the portions in question prevent displacement in any other direction. The thickened portions 9 also serve as anchorages, and in addition toV this they greatly strengthen the bar, in that they serve as braces and tend to resist any crushing or shearing strain upon the bar. Each portion 9, seen in cross section,

alppears to be substantially triangular, and` t1 ese portions 9 are alternated with weaker portions, as will be understood from Flg. 1. From the above description the o eration vof my invention will be readily un erstood.

angular in cross section, it may be seen that A displacement of the bar in any direction is im ossible.

aving thus described my invention, I claim as new and desire to secure by Letters Patent:

A reinforcing bar, comprising a central web crossed by a web formed into a head integral therewith and having two edges, said central web being also crossed by a web formed into a foot so as to ap roximate in cross section an I-beam, each e ge of said head being bent downwardl at intervals so as to present concavities andI being bent upwardly at other intervals so as to present convexities, said concavities u on each edge of said head being alternatedp with the convexities u on the same edge thereof, said foot being ikewise provide with convexities and with concavities staggered relatively to each other, said concavities and convexities of said head being staggered relatively to said concavities and convexities of said foot, and said foot being further provided with thickened portions disposed upon o posite sides of said central web, said thickened portion upon one side thereof being alternated in position with said thickened portion on the o posite side thereof so as'to brace said centra web.

In testimony whereof I have signed my name to this specification in the presence of two subscribin witnesses.
