" LEONARD o. woons, or PITTSBURGH, PENNSYLVANIA.-
JUNCTION FOR METAL BARS.
Application filed September 20, 1927. Serial No. 220,727.
of the curbing, which may be composed oflong angle-bars arranged end-to-end and resting upon and backed by the concrete, and in such case it is evident that if any portion of ajoint between the bars shall project outwardly from the face of the curbing there will be danger of derangement of the joint or of injury to vehicles, such as tearing the tires of motor-cars, passing close tothe curbing.
Inthe accompanying drawings I have shown the invention embodied in the union of two abutting metallic curbing strips. Figure 1 is a perspective view of the joint. Figure 2 is an end elevation of one of the curbing strips. Figure 3 is a side elevation of the ends of two curbing-strips. spaced apart with the preferred form of coupling-1 member between them. Figure 4 is a cross section through the joint on the line IVIV of Figure 3. Figure 5 is a side elevation, and Figure 6 a top plan view, of the preferred form of coupling-member.
The curbing-strips 1 are rolled steel anglebars, the top horizontal wing 2 of which is adapted to rest upon the top face of the concrete curbing, and the vertical Wing 3 to bear against the outer side face. At and adjacent to the edges of the vertical wings 8 the metal'of the strip is bent or offset inwardly or backwardly from the outer face of the strip to form depressions or seats 4 of sufiicient depth to receive the ends of the coupling-members to be described presently,
and inwardly extending horizontal slots 5 are cut in the edges of these depressions, the
depressions 4 and slots 5 being so formed and located that when two strips are brought into end-to-end alignment, the depressions and slots register together. Coupling-mem here 6 are provided to enter the aligned For ex slots 5. These may be of rolled steel, and the slots 5 are of such width as to receive the couplings with suflicient snugness of fit, and the couplings themselves have opposite slots 7 to correspond with the slots 5, their ends 8 being bent down into vertical position so that when the strips are coupled together the ends Sof the couplings will be seated in the depressions '4 beneath the slots. The
space interval between thebases of the slots 7 7 in the couplings 6 is approximatelyequal to the aggregate depth of the two aligned slots 5 in the strips, so that the metal of, the strips behind the'slots 5 enters the slots 7 in the couplings, and a very firm joint is secured. Since the depressions 'orofi'sets 4 inthe strips are of suflicient depth and area to receive the vertically bent ends 8 of the couplings, the joints have no outwardly projecting members, and the outer face of the curbing will be even and smooth.
The rear portions of the couplings 6, be-
hind the slots'7, may be of any desired form, butwhen the strips 1 are used ascurbingstrips as described, it is preferred to provide these couplings with extended arms 9 having downwardly bent ends 10, so that they maybe secured in the sidewalk behind the curbing, and additional firmness will be imparted to the joints.
It will be evident to those skilled in the art that the invention maybe employed in a variety of situations where it is desired to couple metallic bars or strips together in end-to-end alignment, and that while it has been found to be of great advantage'in the construction of street curbing as described, it is not limited toany particular field of employment.
I claim as my invention:
1. Astructural union of two bars brought to. juxtaposition end to end, such union including aligned offsets in the ends of the bars with aligned slots in said ofisets, and a coupling member extending. within said slots and having a bent edge portion seated in said offsets.
2. The combination with a pair of anglebars arranged in end-to-end alignment and having aligning inwardly bent oifsets in their ends and aligned slots in said offsets, of a coupling member engaged in said slots and having a bent edge portion seated in said offsets. I
site end extended backwardly from said bars and adapted to be anchored against movement. I 10 In testimony whereof I have hereunto set my hand.
