CONCRETE-REINFORCE.

Specification 0f Leftferlatentf Patented Sept. 14, 1909.

Application led February 25, 1909. Serial No. 479,944.

To all whom it may concern:

Be it known that I, HERBERT E. VHITE, of Youngstown, in thecounty of Mahoning and State of Ohio, have invented a nei' and useful Coucrete-Reinforce, of which the following is a full, clear, and exact description, reference being had to the accompanying dra" ings, forming part of this specification, in which-v 4 Figure l is a perspective view showing in v improved metal 'reinforciiig structure; and Fig. 2 is a detail view of the -Jonnections between'the tension member and the stay members.

M f invention relates to metallic reinforces, partici'ilarly those employed for concrete beams, though it may be applied to other reinforces. ln suc-h reinforces, it is often desirable to secure members of smaller cross section to a reinforcing bar of much *largerA cross section, and yheretofore it has been difficult or impossible to electricallyY weld such members together, since the smaller iii-einher would burn or meltv away before the larger ineinbei' reached the welding heat. l have discovered that l can overcome this dillicnlty by providing the larger member with a rib or ribs at the welded joint, these ribs being of proper size to electrically weld to the smaller-'member or members.

In the drawing, 2 represents the concrete bar having ribs 3 and 4, projecting from its corners on both sides. The bar may be rolled in this shape or otherwise formed to give the projecting ribs or lips.

5, 5, are inclined strut members, shown as formed of heavy wire that will not bend, their legs fitting against the ribs of the bar. These legs are electrically weldedto the projecting ribs of the bar, this electrical welding being carried out in the ordinary manner. Owing to the reduced section of the i'ibs, as compared with the bar proper, this electrical welding may be easily and effectively carried out. The strut members may be terminated at the lower edge of the bar or may extend below it, or may be arranged in both ways, depending on they location, strains, etc.

The advantages of my invention `result from the providing of a cheap and secure connection between the concrete bar and the member secured thereto.

Variations may be made in the form of the bar, the members connected thereto, and the shape of the ribs, without departing `from my invention.

I claim:

l. As a. ne article of manufacture, a concrete reinforcing bar, having a projecting portion of smaller cross-section than` the body of thebar, and a reinforcing member welded lto said rib, the cross-sectional arcas of the projecting portion of the 'oz and ot' the reinforcing niemher being such that the portions to be welded can be brought to a welding heat in substantially the same period of time; substantially as described.

2. As a new article of nuinufacture, a concrete -reinforcing bar, having a. projecting rib of smaller (.'ioss-section.than the body of the bar, and a reinforcing member having a portion of a cross-section substantially equal to that of the rib, said portion being welded to the rib; substantially as described.

B. As a new article of manufacture, a

metal ba r having a body portion of relatively large cross-section, and projecting ribs each of relatively small cross-section, and a metallic member having a' (-.i'oss-section approxi mately equal to that of each of the ribs, and welded to the ribs; substantially as 4described. l

4. As a new article of manufacture, a con crete reinforcing bar having lateral lribs or projections at opposite sides of relatively sinall cross-sect ioncompared to the cross-section of the body portion of the bar, and shear members each of approximately the same. cross-section as the ribs or projections, alid welded thereto at both sides of the bar; sul-- stantially as described.

5. As a new article ot manufacture, a concrete reinforcing bar, having lateral ribs or projections at opposite sides, said ribs or projections being each of relatively small crosssection compared to that of the body ofthe, bar, and shear members of a cross-section substantially equal to the. cross-section of the .'ad ribs or projections and engaging opposite sides of the bar, and welded to the ribs or projections; substantially as described.

ln testimony whereof, l have hereunto set my hand.

HERBERT E. WHITE.
