. Application filed February 16, 1916. Serial No. 7s,707.

To all whom it may concern Be it known that I, MIKE DEAK, acitizen of the United States, residing at Cuddy, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Rail-Joint Jacks, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to an improved railijoint jack and has for its primary object to provide a simple, durable and-serviceable device for loosening the fish plates at the rail'joints so that the rail sections can be readily removed.

It is a more particular object 'ofthe invention to provide a jack of the above character' for operating upon a boltless rail joint or splice of that character wherein the fish plates-are integrally formed withthe chair plate, said. device including a stationary part adapted to be clamped upon one ,of

the rails, a movable. element adapted to be connected to the joint member, and means for actuating said movable element.

It is another general'object of the inven' tion to simplify and improve the construction of a jack for the above purpose and enable the same to be easily and quickly arranged in operative position, the device as a whole being capable of manufacture at relatively small cost:

\Vith the above and other objects in view, my invention consists in the novel features of construction, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which.

Figure l is a side elevation showing my improved rail joint jack arranged in position upon the rail; Fig. 2 is a sectiontaken on the line 2-2 of Fig. 1: Fig. 3 is a section taken on the line 3-3 of Fig. 1; and Fig. 4: is a detail fragmentary perspective view of the movable rack bar.

Referring in detail tothe drawing, 5 designates the body of the jack which is in the form of an elongated integral casting having a longitudinally extending rectangular bore 6. Upon one end of this casting and from opposite sides thereof, the downwardly diverging foot members or braces 7 obliquely extend and have their lower end faces toothed or serrated for biting engagement into the surface of a tie indicated at T, as clearly shown in Fig. 1.

l casting.

A rack bar 8 is longitudinally movable through the bore 6 of the casting 5 and is provided upon itsupper surface with the teeth 9. One end of this bar is formed wlth a rectangular head=l0 from the end face of which the spaced ears or studs 11 longitudinally project. Upon one end of the casting 5, the aw members 12 are mounted, each of said jaw members having an at 14, upon one side of the rectangular In the-upper end of one of the arms 13 ascrew 15 is threaded, said'screw having a reduced lpo'rtionl6'. terminating in *a circular head 17 which is adapted to bear against the .inner face of the opposed arm 13. The other or outer end of the screw '15 is providedwith suitable means, indicated at lS,'whereby said screw may be con "veniently'turnedor rotated. It is apparent that, by simply adjusting this screw to engage the head 17 against the confronting arm 13, the jaws may be forced inwardly toward each other. I 1 The body casting 5 is formed with upwardly projecting spaced ears 19 which are connected by a fixed transverse rod or axle 20. gear 21 is journaled upon this axle and meshes with the teeth 9. of the rack bar 8.. The arms 22 of a yoke member are loosely engaged upon the ends of the axle 20 and tosaid yoke a suitable handle 23 is 'an upwardly extending arm 27 terminating in a suitable handhold, and from each of these arms, a lag 28 projects inwardly. These lugs have loose pivotal engagement upon the respective pins or studs 11 projecting from the end face of the head 10 on the rack bar 8.

In the drawing, I have shown a wellknown type of joint member for the abutting ends of rails, which consists of the chair plate C with which the fish plates P are integrally formed, said plates extending upwardly over the rail base and against the opposite sides of the web of the rail upwardly extending arm 13 fulcrumed, as 1 indicated at R. Upon each of the fish plates, a reinforcement is formed and these justing the screw 15 so as to securely clamp the jaws 12 against the opposite sides of the rail, the jaws 26 are arranged against the outer faces of the fish plates P contiguous to the reinforcement thereon. The handle member 23 is now oscillated, and in each movement of the same in one direction, the pawl 24: engaging the gear 21 rotates the latter and imparts a rectilinear movement to the rack bar 8, thus causing the jaws 26 to exert pressure against the abutments and thereby shift the joint member and loosen the connection of the fish plates with the rail. After thus loosening the joint memher, the two rail sections can be readily re- 'moved.

From the foregoing description, taken in connection wlth the accompanying drawing, the construction, manner of operation and several advantages of the invention will be clearly and fully understood.

The device may be very easily and quickly arranged in its operative position upon the rails and requires but little manual exertion in order to operate the same and readily shift the fish plates into position so that the rails can be removed.

lVhile I have herein disclosed a particular form, construction and mounting of the jaw members, it is apparent that in this particular, the device is capable of considerable modification.

I also reserve the privilege of adopting various other changes in the form, proportion and arrangement of the several cooperative elements of the invention and I, therefore, wish it to be understood that I reserve the privilege of adopting all such legitimate changes as may be fairly en1- bodied within the spirit and scope of the invention as claimed.

Having thus fully described my invention, what I desire to claim and secure by Letters Patent is 1. A device of the character described including a body member means carried by saidmember for anchoring the same in position upon a rail tread, said member having a longitudinal bore, a rack bar longitudinally movable through said bore, means on said bar adapted for engagement against abutments on joint fish plates, and manually operable means carried by the body member and cooperatively engaged ,withthe rack bar to move the same and cause the means thereon to exert a pressure against the abutments and shift the fish plates longitudinally of the rail.

2. A device of the character described including an elongated body member having a longitudinal bore and provided on one end with obliquely disposed anchoring braces, means on the other end of the body member to clamp the same in position upon a rail tread, a rack bar longitudinally movable in the bore of said body member, a gear mounted upon the body member and cooperatively engaged with the teeth of the rackbar, opposed jaws mounted upon one end of said rack bar and adapted for engagement against abutments on joint fish plates, and means mounted upon the body member to manually rotate said gear and actuate said rack bar to cause the jaws thereon to exert a pressure against the fish plate abutments and shift the fish plates longitudinally of the rail.

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

, MIKE DEAK.
