RAIL-JOINT.

Specification of Letter P n Patented J an. 13, 1914.

Application filed May 1, 1913. Serial No. 764,856.

To all whom it may concern:

Be it known that I, J noon HOMER Roe- BINS, a citizen of the United States, residing at Gillespie, in thecounty of Macoupin and i State of Illinois, have invented certain new and useful Improvements in Rail-Joints, of l which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to rail joints and has for its object the production of a simple and efiicicnt joint which may be connected without means of bolts or other securing members, and which will remain in engagement without danger of coming apart.

Another object of this invention is the production of a rail joint which is provided with a simple means for allowing the rail to expand or contract, due to atmospheric conditions.

Vith these and other objects in view, this invention consists of certain novel constructions, combinations and arrangements of parts as will be hereinafter fully described and claimed.

In the accompanying drawings: Figure 1 is a perspective view of a portion of a railroad track showing the improved joint used in connection therewith. Fig. 2 is a central longitudinal section taken through the rail joint. Fig. 3 is a transverse section thereto. Fig. 4. is a bottom plan view of the device showing a portion of the same in dotted lines. Fig. 5 is a perspective view of the primary rail which carries the depending lug. Fig. 6 is a perspective view of the auxiliary rail which is used in combination with the primary rail. Fig. 7 is a longitudinal section of a slightly modified form of a rail joint. Fig. 8 is a perspective view of a portion of the primary rail used in connection with the modified form. Fig. 9 is a perspective view of a portion of the rail showing a slightly modified form which is used in connection with the form disclosed in Fig. 8.

Referring to the accompanying drawings by numerals, it will be seen that the primary rail comprises a tread 1, flange 2 and web 3. The web 3 is provided at its end portion thickened portions 4: which are provided with a slot 5 in which the de pending lug 6 is positioned, the depending of the tread 1. The auxiliary rail used in connection with this primary rail comprises a tread 1, flange 2, and web 7, the web 7 being provided with an extended portion 8 in which there is formed an elongated slot 9.

When the form above described is used, the rails are so positioned as to allow the depending lug. fito be positioned within the slot 9. The rails are then spiked to the ties, and in this manner will be held in firm engagement with each other. The extended portion 8 fits entirely within the slot 6 and in this manner holds the end portions of the rail in alinement with each other, while the lug 6 being in the slot will prevent the portions from coming apart. It will'further be noted that the slot 9 is considerably longer than the breadth of the lug 6 and therefore allows the lug 6 to slide within the slot 9, when the rails expand due to hot weather, or when they contract owing to the cold weather, and in this manner prevents the rails from bulging up at the joints and forming a rough joint.

In the modified form there is provided the usual tread 10, flange 11 and web 12. The tread 10 extends considerably beyond the end of the flange 11 and web 12 and carries a depending lug 6. The auxiliary rail used in connection with this primary rail comprises a tread 13, extending for considerable distance beyond the end portion of the tread 13, the web 15 being provided with an elongated slot 16. When this form is used, the lug 6 is positioned within the slot and since the flange 14: is positioned upon the under portion of the web 15 and the tread 10 extends beyond the flange 11, there will be provided an efiicient means for supporting the tread 10. It will also be noted that this form is provided with a lug which is considerably smaller than the length of the slot 16 so as to allow the lug to slide back and forth with in the slot when the rail expands or contracts due to atmospheric conditions.

Fro-m the foregoing description it will be seen that a simple rail joint has been produced which will efliciently connect the rails together without the aid of a secondary securing means which will allow the rails to expand or contract due to atmospheric conditions without danger to the rails coming lug 6 being formed upon the lower portion apart.

flange 14c and web 15,

Having thus described the invention, what is claimed as new, is:

A rail joint comprising a primary section secured to an auxiliary section, said primary section provided with bulged portions adjacent its lower portion, said bulged portion provided with a slot, a depending lug carried by said rail and positioned within said slot and at a determined distance from the side portions thereof, said auxiliary section provided with an elongated slot in its lower portion, elongated slot for holding said rails in en gagement with each other, said slot being said depending lug fitting in said longer than the breadth of said lug for allowing said lug to slide to and fro when the rail expands or contracts, due to atmospheric conditions, and the portion of said auxiliary rail which carries the slot fitting within the slot formed in said primary rail for holding the end portions of said rails in alinement.

In testimony whereof I hereunto affix my signature in presence of two witnesses.
