BAIL-JOINT.

Specification of Letters Patent.

Patented July 8, 1919.

Application filed February 4, 1919. Serial No. 274,855.

T 0 all whom it may concern Be it known that I, FELIX ENGLOT, a citizen of England, residing at Lemberg, Prov. of Saskatchewan, and Dom. of Canada, have invented certain new and useful Improvements in Rail-Joints, of which the following is a specification.

This invention relates to improvements in means for securing the abutting ends of railroad rails firmly together.

The principal object of the invention is to provide means whereby the abutting ends of track rails may be firmly secured without use of fish plates, bolts or other like mechanical devices, the ends of the rails being so united as to resist tensional strains tending toward separation and also to provide against lateral strains whereby the rail ends might become out of alinement.

These and other like objects are attained by the novel construction and combination of parts hereinafter described and shown in the accompanying drawings, forming a material part of this disclosure, and in which Figure 1 is a fragmentary perspective view showing a pair of abutting rails and indicating the manner of their connection.

Fig. 2 is a perspective view showing the end of one of the abutting rails, and

Fig. 3 is a similar perspective view showing the end of the adjoining rail.

Referring to the drawings, a conventional type of rail is indicated, the same comprising a head 10, stem 11 and flange base 12.

Formed vertically through the center of the head of one of the rails is a dove-tailed mortise having a rear wall 14:, the extending portions 15 being coincident with the extremity 16 of the base while the wall 14 is in vertical alinement with the rear or shoulders 17 of the lateral recesses in the base 12, the projection 18 therebetween being narrower at its point of connection with the wall 17, than at its outer edge 16 forming a dovetailed tenon.

Formed in the shortened end of the web of stem 11 of the rail is a vertical shaped recess 19.

The opposite rail has its head 10 formed with the tenon 20, its angular sides 21 being fitted to engage between the projections 15, while its straight, outer face 22 is engageable with the rear wall 142 of the mortise in the abutting rail head 10.

Extending downward in register with the surface 22 is the front edge 23 of the end of the stem 11 of the rail, its beveled sides 2% being engageable within the corresponding vertical angular recesses 19 of the stem 11 of the adjacent rail, and slightly overhanging the wall 25 of the mortise formed in the base 12, this mortise being adapted to receive the tenon 18 formed with the base 12, while the extreme ends 26 of the rail, on either side of the mortise 27, are in vertical alinement with the projecting tenon 22, and make con tact with the surfaces 17 of the base 12.

The peculiar shape in the ends of the rails is formed either by processes of forging or machining and it will be obvious that when the parts are interlocked, lateral motion of one of the rails, relative to the other is absolutely prevented, as well as separation of the rails in the direction of their length.

Thus this simple device may be safely used in securing the abutting ends of rails without drilling or weakening the stems or flanges, presenting a relatively level, well supported surface over which a car wheel may pass without ar, causing vibration to the car, while the interlocking elements serve to hold the contiguous rails firmly and closely united.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

In rail joint device, the combination with a pair of running rails comprising heads. stems and flanged bases, of a clovetailed recess forn'ied in the head of one of said rails, a. vertical V shaped groove formed in the stem of said rail, and a dovetailed tenon extending from the base of said rail, the inner end of said tenon and the bottom of said recess being in vertical alinement, a corresponding tenon formed with the head of the mating rail, a beveled edge formed with the stem of said mating rail, and a dove-tailed recess formed in the flange of said mating rail, said dove-tailed recess being receptive of the corresponding tenon in the first named rail whereby the two rails are held against relative lateral movement and against longitudinal separation.

In testimony whereof I have afiixed my signature.

FELIX ENGLOT.
