RAIL-JOINT.

Specification of Letters Patent.

Patented June 2, 1914.

Application led March 28, 1914. Serial No. 828,070.

To all whom. t may concern Be it known that we, Fanncrsznn KLI- iunoznn and JACOB Znnnznniii, subjects of the Emperor of Austria-Hungary, residing at Filbert, in the county of McDowell and State of West Virginia, have invented certain new and useful Improvements in Rail- Joints, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relatesv to rail joints and has for its object to provide means, in a manner as hereinafter set forth, for connecting together the opposing ends of a pair of track rails without the employment of nuts, at the same time allowing for the necessary contraction and expansion of the track rails o due to climatic infiuences.

Further objects of the invention are to provide a rail joint which is comparatively simple in its construction and arrangement, strong, durable, efficient and convenient in its use, readily set up and inexpensive.

Vith the foregoing and other objects in view the invention consists of the novel construction, combination and arrangement of parts as hereinafter more fully described and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto appended.

In describing the invention in detail reference is had to the accompanying drawings wherein like reference characters denote corresponding parts throughout the several views, and in which Figure 1 is a side elevation of a pair of track rails, showing the adaptation therewith of a rail joint in accordance with this invention; Fig. 2 is a sectional plan of Fig. 1

1; Fig. 3 isa central transverse section of Fig. 1'; Fig4 is a detail illustrating a portion of the locking plate; Fig. 5 is a detail illustrating a portion of one of the fish plates.

Referring to the drawings in detail, 6 and 7 denote a pair of track rails, and each includes a head 8, web 9 and base 10. Arranged at one side of thewebs 9 and engaging the heads S and bases 10, is a fish plate 11, and arranged at the other side of the webs 9 and engaging the heads 8 and bases 10 is a sh plate 12.

The fish plate 11 is provided with a series of square openings 13 arranged in alinement with eircul ar openings 14 formed in the webs 9, and extending through the alining openings 13-14 are bolts, each including a head 15, and a shank having a squared portion 16 and a cylindrical portion 17, the latter having its periphery provided with oppositely disposed grooves 18. The heads 15 of the bolts abut against the outer face of the iish plate 11, the squared portions of the shanks of the bolts being seated in the openings 13, and the ylindrical portions 17 of the bolts projecting through the openings 14 and into the fish plate 12.

The fish plate 12 is provided with a series 4of longitudinally extending keyhole-shaped openings 19, and the contracted portion of each of said openings is indicated at 20. Each of the longitudinal walls of the contracted portion 20 of each of the openings is beveled in opposite directions as illustrated clearly in Fig. 3, and the said beveled walls are adapted to seat in the grooves 18 of the shanks of the bolts whereby lengthwise movement of the bolts is arrested. The cylindrical portions 17 of the shanks of the bolts are first entered in the enlarged portion of the keyhole-shaped openings 19, after which the lish plate 12 is shifted in a direction whereby the beveled walls of the contracted portion 20 of the keyhole-shaped openings will engage in the grooves 18 of the cylindrical portions 17 of the shanks of the bolts.

For maintaining the cylindrical portion 17 of the shanks of the bolts in the contracted po-rtion 2O of the keyhole-shaped openings, retaining lugs 2l are employed, and which are so shaped as to allow of their being positioned not only in the enlarged portions of the keyhole-shaped openings, but to project into the contracted portion 20 of said keyhole-shaped openings and engage the cylindrical portions 17 of the shanks of the bolts, as clearly illustrated in dotted lines in Fig. 1, whereby the bolts are prevented from lengthwise movement, and the sh plate 12 from longitudinal movement upon the shanks of the bolts.

The retaining lugs 21 are carried by a plate 22 which is arranged against the outer face of the fish plate 12, and the said plate 22 is enlarged centrally as at 23, and formed centrally of its inner face, as at 24, with a pocket, and further provided centrally with an opening 25 having a round threaded wall.
