Specification of Letters Patent.

Patented Juiie 27, 1916'.

Application filed October 13,1915. Serial No. 55,699.

Be it known that I, HENRY EMERY Comimic, a subject of Great Britain, residing at West Milan, in the county of Coos and State of New Hampshire, have invented new and useful Improvements in Rail- Joints, of which the following is a specification.

The invention relates to improvements in rail joints, and has special reference to means for facilitating the application of rail joints in laying rails.

To this end the invention has primarily in view a simple, novel and practical expedient which will enable trackmen to apply rail joints to rails with facility and accuracy, and in a like manner to permit of the separation of the members comprising the joint should either of the rails or any of the members of the joint become worn and thereby supplanted by a new part therefor.

Another object of the invention is to construct the rails with interengaging ends; to provide a rib member for engaging a groove in the base of said rails and to further 'provide a sleeve which is adapted to be moved longitudinally over the base portion of the rails to envelop the rib member and lock the interengaging ends of the rails to hold the said rails in positive alinement.

A further obje'ct'of the invention is to construct a rail having its web enlarged at its end and sheared or stamped to provide vertically disposed lapping sides, the ends of which being received in depressions provided above the base of the rail on said sheared or stamped portions thereof, and further to provide the rail ends with a thickened base which extends below the base proper, to form the said thickened portion with a longitudinally extending groove, to

receive the rib of the rib member, the ends provided by the channel of the said me'mber contacting wit'h the inner ends of the thickened portions of the base of the rail, to provide a slidable sleeve upon one of the rails ada ted to be moved over-the member provided with the rib well as to engage with the upper horizontally straight base" portion of the rail in positive engagement.

Removable means are provided for retainng the sleeve in locked positions upon the oint, and thus produce a joint which will retain the rails against lateral or vertical movement and to permit only a limited longitudinal movement incident to the expansion and contraction or the rails and to further render the rails at the oint thereof of a strength as great, if not greater, than at any other portion of the rails.

A stillfurther objectof the invention to produce a rail joint which will embody the desirable features of 'che'apness, simplicity, durability and eflic'iency.

The essential features of the device in volved in the provision of arail joint arenecessarily susceptible of a range of structural modifications without departing from the scope of the invention, but desirable illustrative embodiments of the latter are shown -in the accompanying drawings, in which: V

parts being broken way, and parts being shown In section, Flg. 5 1s a detail transverse section approximately on the line 5-5 of y Fig. 4:, Fig. 6 is a perspective View of one-of th rail ends, Fig. 7 is a similar view of the ribbed base member or block, and Fig. 8 is a similar View of the locking sleeve;

In carrying out my invention, the rails I the rails, at'th'e said horizontally straight portions 2 being thickened upon theirunderfaces to provide, substantially re'ctangu-. lar depending members 3, and these meta bers, from the outer and straight walls 4 thereof and upon their underfaces are formed with a centrally arranged groove 5, the upper wall of which being arranged in a line flush with the underfaces of the base of the rail. The head of each of the rails, at the thickened web thereof, which, for dis tinction, is indicated by the numeral 6, is sheared or stamped to provide an extension 7, the inner vertical wall 8 of which being arranged centrally and longitudinally of the rail and terminating in a transverse shoulder 9. The extension 7 projects a distance beyond the end wall t equal to the distance between the said end wall and the shoulder 9. The depending or widened portions 3 of the base are only slight, approximately onehalf of an inch, and the lengths of the said members 3 are approximately two inches in length, so that it will be noted that the extension 7 provides a tongue which is also of a comparatively short length, and as the question of dimensions becomes a matter of prime importance in the process of manufacture, the forging or stamping of the rail. ends, which, it will be noted are of a similar construction at both the ends of the rails, can be made from the same die or machine, so that precision, rapidity and economy in stamping the rail ends will be assured.

-This is, of course, of practical importance both from a manufacturing standpoint and from an engineering standpoint. It will be further noted that except for the tongue 8 no other projections are provided upon the rail ends which might interfere with the free removal of the rail should it be found necessary to remove either of the rails, and When the rails. are assembled the projections or tongues 8 lap.

The oint includes a base member or block 10 which has itsupper face channeled transversely to provide. a horizontally straight portion 11 and vertical shoulders 12 which provide the end walls of said straight portion 11. The block is also centrally formed with a longitudinally extending rib 13 which connects the shoulders 12, and the said block adjacent one of its ends and adjacent its lower face is formed with a transverse head or flange 14. The distance between the shoulders 12 is slightly in excess of the combined width of the depending portions 3 of the base of the rails and the block is applied by simply slipping the same over the rails to bring its rib 13 within the grooves 5, the shoulders 12 being disposed adjacent the vertical end walls 15 provided .by the depending portions 3. However, be-

fore the block 10 is thus positioned the slidable sleeve 16 is arranged upon one of the rails and moved a distance away from the end of the said rail. This sleeve comprises a substantially rectangular hollow member of an interior width approximately equaling the width of the block 10 which corresponds with the width of the base flanges of the rails and of course the width of the depending portions 3 at the ends of said ribs. The interior height of the sleeve equals the distance between the lower face of the block 10 and the horizontally straight surface 2 provided upon the rail ends. The top member 17 of the sleeve is cut centrally and longitudinally forming the same with an opening 18, the width of which being equal to the width of the thickened ends of the rails. After the block has been positioned, as previously stated, the sleeve is forced longitudinally over the horizontally straight portions 2 of the rail ends and underface of the block until. one of the ends of the sleeve contacts with the flange or bead 14-. The inner surfaces of the sleeve engage with the block, the sides of the vertically straight depending portions 3 of the ends and the upper horizontal surface 2 of the base flanges of the rails, as well as with the sides of the widened portions 6 and the outer surface of the tongues or extensions 7 with siuiicient friction to normally prevent the accidental removal of the sleeve from the joint, but in order to positively lock the said sleeve upon the joint, the widened end of the block 10 opposite that provided with the bead 1 1 is formed with a transverse opening 19 through which is passed a securing element 20, the same being preferably in the nature of a cotter pin and has its ends bent in opposite directions, so that the head thereof as well as the said bent ends will contact with one of the ends of the sleeve and thus effectively hold the sleeve in locked position.

A rail joint constructed as above described, has the advantages of simplicity and strength which will be apparent to those skilled in the art to which such inven tion appertains and while other embodiments may present themselves to those familiar with the art, it is believed that the device as herein described will exemplify the uses and advantages of the improvements claimed.

Having thus described the invention, what I claim is:

1. In a rail joint, two rails having lapping ends each resting upon the base of the other rail, a block having a rib which is arranged in a groove in the underface of the base flanges of the rail, and a slidable sleeve contacting with the rail ends enveloping the block. 7

2. In a rail joint, two rails having reduced head and web extensions which are adapted to lap and one to rest upon the base of the other, said rails having their underfaces provided with alining grooves, a number having a rib which is received in the grooves, and a slidable sleeve contacting with the rail ends and the extensions thereof engaging with the rib member and sustaining the rib in the grooves.

3. In a rail joint, two rails having reduced head and web extensions which are adapted to lap and one to rest upon the base of the other, said rails having their underfaces provided with alining grooves, a member having a rib which is received in the grooves, and a slidable sleeve contacting with the rail ends and the extensions thereof engaging with the ribbed member, and means for locking the sleeve in such position.

4. In a rail oint, two rails having reduced head and web extensions which are adapted to lap and one to rest upon the base of the other, said rails having their underfaces provi ded with alining grooves, a member having a rib and said rib received in the grooves, and a slidable sleeve contacting with the rail ends and the extensions thereof engaging with the ribbed member, and removable means for locking the sleeve in such position.

5. In a rail joint, two railshaving their webs widened at the ends thereof, their base flanges elevated to provide horizontal portions, thickened below the said horizontal portions, the said thickened portions being centrally formed with a groove. the head of the rail extending beyond the thickened base and being sheared'or stamped to provide a lateral tongue and a transverse shoulder which is disposed over the horizontal portion of the base and the said extensions adapted to lap and have their ends contact with the shoulders and rest on the horizontal upper face of the base to bring their grooves in register, a block having a depressed upper face providing a central longitudinal rib adapted to be received in the grooves and having the end walls provided by the depressions disposed adjacent the inner ends of the depending portions ofthe base, and a longitudinally movable sleeve arranged upon the flanges elevated to provide horizontal portions, thickened below the said horizontal portions, the said thickened portions being centrally formed with a groove, the head of each rail extending beyond the thickened base and being sheared or stamped to provide a lateral tongue and a transverse shoulder which is disposed over the horizontal portion of the base, and the said extensions adapted to lap and have their ends contacting with the shoulders and rest on the horizontal upper face of the base to bring their grooves in register, a block having its upper face depressed and centrally formed with a longitudinal rib which is adapted to be received in the grooves of the rails, said block having its underface adjacent one of its ends provided with a stop bead and its opposite end provided with a transverse opening, a substantially rectangular sleeve arranged upon one of the rails, said sleeve having its upper face provided with a central longitudinal opening of a width approximately equaling the width of the widened ends of the said rails, said sleeve adapted to be moved longitudinally over the rail ends and the block to contact with the stop head of the block, and a locking element passing through the opening in the block and contacting with one of the ends of the sleeve.

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