EVERETT W. PREBLE, OF ANSON, MAINE.

RAIL-JOINT.

To all LO/LOl/b it may concern Be it known that I, EVERETT W. PREBLE, a citizen of the United States, residing at Anson, in the county of Somerset and State of Maine, have invented new and use ful Improvements in Rail-Joints, of which the following is aspecification. V

The present invention relates to improvements in rail joints, and resides in the construction, combination and arrangement of parts set forth in the following specification and falling within the scope of the appended claims.

In the drawings there has been illustrated a simple and satisfactory reduction of my improvement to practice, it being understood that the important instrumentalities thereof may be varied so I am entitled to such changes in form, proportion, etc., as fall within the scope of the claims.

In the drawings: Figure 1 is a perspective view illustrating my improvement connecting the ends of two contiguous rails, Fig. 2 is a central horizontal sectional view through the same, Fig. 3 is a transverse sectional view taken approximately in aline with one of the retaining bolts of the joint illustrated in Fig. 1, Fig. 4 is a bottom plan view of the improvement, Fig. 5 is a perspective view of one of the joint chair members, the bolt cushioning block and the plate therefor being removed, Fig. 6 is a similar view of the co-acting chair member, and Fig. 7 is a perspective view of the bolt cushioning block.

With a rail joint constructed in accordance with my invention, I aim to so arrange the parts that the chair members of the joint will interlock and be reinforced at their portions upon which the rail ends are received, so that the said ends will be amply supported without danger of either lateral or down ard movement, and also to provide the chair members with projecting plates having spike openings which engage with the base flanges of the rails and which will prevent the longitudinal displacement of the joint as well as a free longitudinal movement of the rail ends. I also aim to provide a pair of joint chair members having angular sides which occupy the fishing spaces of the rails, one of said chair members having a longitudinally extending depression or pocket for the reception of a cushion member, formed of wood or the like, through which the bolts that connect Specification of Letters Patent.

the webs of the rails with the sides of the chair members pass, so that the said bolts will be relieved from undue strain incident to the rolling stock passing over the joint, and thus the connecting nuts for the bolts, not being subjected to vibratory movement, will be effectively sustained upon the bolts.

Referring now to the drawings in detail, RR designate two rails which are of the ordinary construction and which are adapted to have their ends abut. The joint for the rail ends comprises essentially two rail chair members, designated by the numerals 1 and 2 respectively. The chair member 1 includes an elongated base 3 which is horizontally straight and which has its ends widened, as at 4. Iutegrally formed upon one side of the base 3, at the juncture of the widened portions of the ends is a reinforcing member 5 which projects both above and below the said base. The inner face of the portion ofthemember 5 which extends above the base plate 3 is formed with a continuous channel, the inner wall of which being slightly curved inwardly and communicating with the base proper, as indicated by the numeral 6, and the upper wall provided by the said channel is beveled from the wall 6 to the inner face of the reinforcing member 5 and indicated by the numeral 7. The inclined wall 7 overlies the base 3, and terminates in a vertical wall 8. The inner face of the reinforcing member, above the plate 3, is thus shaped to be received within the fishing spaces upon one of the sides of the rails It, and the vertical wall 8 is provided with transverse openings 9 which are adapted to register with similar openings in the webs of the rails It. The outer face of the upper portion of the reinforcing mem: ber 5 is provided with a longitudinally extending pocket 10, the lower wall of which being beveled, as at 11, and the corners of the outer face of the member 5 are enlarged to provide additional reinforcing members 12. The outer face of the portion 5, below the pocket 10 terminates centrally in a horizontally straight wall 13, while the lower ends of the said reinforcement are inclined or beveled from the said horizontal wall to their connection with the underfaces of the base plate 3. The lower portion of the reinforcing member 5 terminates approxi mately central of the plate or base 3, and is vertically straight, the said wall being recessed throughout its length at its juncture with the underface of the plate to provide a groove 14, and a tongue 15 which is disposed below the groove.

The openings 9 enter the pocket 10, and adapted to be received within the said pocket is a cushion member 16 which conterms in shape and which is adapted to be snugly engaged by all of the walls of the pocket. The cushion member is preferably formed from a block of wood, and is pro-" vided with openings 17 which are adapted to register with the openings 9. The cushion 16 is retained within the pocket through the medium of a substantially rectangular plate 18, and this plate is also provided with openings which register with openings in the cushion member as well as with the openings 9. The reinforced corners 12 are incut at their juncture with the lower wall of the pocket to provide shoulders 19.

The second rail-chair member 2 comprises a fiat base 20, the outer face of which being enlarged, and the inner portion of the said enlargement being channeled, as at- 21, to provide the portion above the channel with a vertically arranged longitudinally 7 extending member 22 which, with the upper wall of the channel, is shaped to engage the base flanges and fishing spaces upon the side of the rails to which the member 2 is to be connected. The channel 21 is of sufficient depth to permit of the base 20 being arranged below the base 3 of the chair member 1, and the bottom as well as the outer face of the chair 2 is enlarged, as at 23, the inner face of the enlargement terminating a distance away from the inner longitudinal edge of the base 20, so that the portion ot the base extending from the said vertical wall is formed with what may be termed, a tongue 24, and this tongue is adapted to be received within the groove 1-1 of the chair member 1, while the tongue 15 provided by the chair member 1 is received within the depressed portion of the enlargement 23. The outer corners of the chair member 2 are reinforced, as at 25, and the said chair 2 is of a length corresponding with the distance between the shoulders provided by the widened end portions 4 of the base 3, so that when the chair members are assembled, the chair 2 cannot move longitudinally of the chair 1. The enlarged portions of the base, at the lower parts thereof, are provided with registering openings which pass below the tongue 24 of the member 2 and through the tongue 15 of the member 1, and these openings are adapted for the reception of securing elements, in the nature of bolts 26, and nuts 27. The vertical member 22 of the chair 2 is provided with openings, which are adapted to register with the openings of the vertical member of the chair 1, as well as in the cushion member 16 and plate 18, the alining opening receiving the usual securing bolts 28 which are provided with retaining nuts 29. The widened ends of the base 3 are each formed with spike openings 30 which are so arranged that when the spikes are passed therethrough and into the ties T, the heads of the spikes S will even lap-and engage with the base flanges of the rails.

From the above description, taken in connection with the accompanying drawings, the simplicity of the device as well as the advantages thereof will, it is thought, be perfectly apparent to those skilled in the art to which such inventions appertain withoutfurther detailed description.

Having thus described the invention, what I claim as new is:

1. In a rail joint, two chair members, one of which being provided with a base upon which the rails rest, the said base having widened ends provided with spike openings, which are so disposed as to permit of the heads of the spikes engaging with the base flanges of the rails, the said chair having a central enlarged portion shaped to engage with the fishing space of the rails, the said enlargement being extended below the base plate and having its inner wall approximately central of the longitudinal plane of the said plate and the said inner wall being channeled to provide a. tongue and a groove, the second chair being of a size adapted to fit between the enlarged ends of the first mentioned chair and to have its ends contact with the shoulders provided thereby, the said second chair having a base which is adapted to underlie the base of the first named chair and having its inner face enlarged and channeled to provide a tongue and groove which co-act with the tongue and groove in the underface of the enlarged portion of the first mentioned chair, the second mentioned chair having its portion arranged above the base shaped to engage with the fishing spaces of the rails, and means connecting the upper portions of the chairs with the webs of the rails.

2. In a rail joint, two rails, said joint including two chair members which are adapted to engage with the fishing spaces upon the opposite sides of the rails, one of said chairs being provided with a base upon which the rails rest, the said base having enlarged ends provided with spike receiving openings, the said openings being arranged to permit of the heads of the spikes contacting with the base flanges of the rails, one of the chairs having a central enlarged portion which extends both above and below the plate, the upper portion of said enlargement having end reinforcements, the outer face of said portion being recessed to provide a pocket, a cushion member for the pocket, a plate for closing the pocket, the second rail chair adapted to engage the base plate on the opposite side of the enlargement and to be disposed between the enlarged ends of said chair and to contact with the ends, the ends of the second mentioned chair having reinforcements, the portions of each of the chairs extending below the base having tongues and grooves, means comprising nuts and bolts for securing the said depending portions, the upper portions of the chairs as well as the cushion and pocket closing plate being provided with openings which register with openings in the webs of the rails, and bolts passing through the said openings, and nuts for the bolts.

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