RAIL-JOINT.

SPECIFICATION forming part of Letters Patent No. 790,633, dated May 23, 1905.

Application filed January 18, 1905. Serial No. 241,555.

To wZZ whom it may concerm Be it known that 1', CARL HAMAN, a citizen of the United States of America, residing at Rochester, in the county of Beaver and State ofPennsylvania, have invented certain new ticularly to that type wherein the use of nuts and bolts is entirely dispensed with.

The object of this invention is to provide novel means whereby two sections of rails can be firmly locked together in such a manner as to prevent longitudinal or lateral movement of either section.

Another object of this invention is to provide a rail-joint which will eifect a great saving in, maintenance and which is also suitable for elevated structures and long bridge-spans, as well as the ordinary road-bed of'railways.

The rail-joint as constructed by me is of a special nature and is adapted to withstand the Vibratory stresses which are incurred by the rolling-stock passing over the same.

A further object of this invention is to provide a rail-joint of asimple construction which can be readily manufactured by shearing the confronting ends of two rail-sections, whereby they will interlock one within the other.

The construction entering into the invention will be hereinafter more fully described and then specifically pointed out in the claims, and, referring to the drawings accompanying this application, like numerals of reference designate corresponding parts throughout the several views, in which- Figure 1 is a side elevation of my improved rail-joint. Fig. 2 is a top plan view of the same. Fig. 3 is an end view of one of the rail-sections. Fig. 4: is a perspective view of the confronting ends of two rail-sections, and Fig. 5 is an end view of the rail-section opposing that end of the rail illustrated in Fig. 3 of the drawings.

To put my invention into practice, I employ the ordinary type and weight of rail as designated by the reference- numerals 1 and 2,

and the ends of these rails I shear or saw, whereby they will interlock one within the other. The end of the rail-section 1 has its head or tread cut away, as indicated at 3, forming a web portion 4, having shoulders 5 5, this web portion and the shoulders being with a slot 8 centrally of the base portion, alining with the web 6 of said rail. The sides of the raised portion 7 are provided with cutaway portions 9 and 10 10..

, The end of the rail-section 2 has its web 11 cut away, as indicated at 12, and the under face of the head ortread 141 of the rail, which protrudes outwardly over the cut-away portion 12, is provided with a groove 15. This groove is adapted to receive the web portion 1 of the rail-section 2 when the ends of the rails are secured together. The base portion 16 of the rail-section 2 is provided with a raised portion 17, and the one side of the raised portion is cut away, as indicated at 17 said cutaway portion extending to the opposite edge of the web 11, as indicated at 18. Theunder face of the base 16 is cut away, forming recesses 19 and 20, and in forming therecess 20 the base 16 of the rail-section 2 is cut away beneath that portion of the raised portion 17 which extends beyond the cut-away portion 17 The formation of the recesses 19 and 20 provides a central rib 21, and the sides of the raised portion 17 are cut away, as indicated at 22 and 23 23.

When joining the ends of the rail- sections 1 and 2, the end of the rail-section 2 is placed down over the end of the rail-section 1, and the head or tread lei of the rail-section 2 seats upon the shoulders'5 5 and the web portion 4: of the rail-section 1. The central rib 21 is adapted to engage in the slot 8 of the railsection 1, and the raised portions 17 of the base of the rail 2 are adapted to overlie the raised portions 7 of the rail-section 1. The raised portions 7 of the rail-section 1 seat within the recesses 19 and 20 of the rail-section 2, and when these rail-sections are so joined the cut-away portions 9 and 22 of said railsection are adapted to vertically aline,

and the cut- away portions 10 and 23 are adapted to aline with one another, whereby spikes may be placed in said cut-away portions and driven into a tie (not shown) adapted to support the rail-joint.

By the construction illustrated in the accompanying drawings it will be seen that the metal which is sheared or cut away from the confronting ends of the rail-sections is used in the raised portions 7 and 17 of the base portions of said rails, this being accomplished by upsetting the metal formed in the base of the rails. he interlocking of the ends of the rails obviates the pounding of the wheels of the rolling-stock when passing over the joint, this feature increasing the life of the railjoint and the wear and tear upon the rollingstock.

It Will be noted that various changes may be made in the details of construction without departing from the general spirit and scope of the invention.

WVhat I claim, and desire to secure by Letters Patent, is

1. Arail-joint comprising two rail-sections, having interlocking ends, the bases of said rail-sections having raised portions formed thereon, the Web portion and raised portion of one rail-section being cut away to accommodate the web and raised portion of the adjoining section, the under face of the head of one rail-section having a groove formed therein, to accommodate the web portion carried by the adjoining rail-section, and means to secure said rail-sections together, substantially as described.

2. A rail-joint comprising two rail-sections having interlocking ends, the bases of said rail-sections having raised portions formed thereon, the web and raised portion of one section being cutaway to accommodate the raised portion and web of the adjoining section, the raised portion of one section being provided with a depending rib, the raised portion of the adjoining section having a slot formed therein to accommodate said rib, the head of one rail-section having a slot formed therein, the head of the adjoining section being cut away to form a web portion and shoulders to support the grooved head of the adjoining section, the raised portion of one section'of rail being adapted to overlie the raised portion of the adjoining section, and means to secure said raised portions together, substantially as described.

' In testimony whereofl affix my signature in the presence of two witnesses.

CARL HAMAN.
