RAILRoAD-.JACK- SPECIFIQATIONforming part of `Letters Patent No.. 249,488, dated November `15, 1881. Appnefinou nieu september is, i881. (No model.)

To all whom it may 'concern :y i

Be it known that we, ISRAEL SHOUDY and JOHN; LICHER, citizens of the United States,`

' use on the track ot' railroads, to raise one `o`r both rails for thepurpose of leveling the track,

or for other purposes requiring the rails to be raised; and it consists in the devices and the combinations of devices represented inthe ac-Y companying drawings, in which- Figure l is an isometrical representation of our improved jack as applied in use. Fig. 2 is acentral section of one of theratehet-Win dlasses lengthwise of its axis. Fig. 3 is a transverse sectioncut ceutrallyof theleveraud its ratchet, and Fig. et is a vertical central section of the pawl-detaching mechanism. o

In the figures, A represents the sills, and B the rails, of a railroad-'track spiked to the sills in the usual manner.

At C is represented the sill of our improved jack, which in this instance is a plank rectangular in planand section, and of suitabledimensions.

At D are represented vertical posts, rectangular in section and of proper dimensions, having their lower` ends securely xed to the corner portion of the sill, from which they rise to a proper height.

i At E and F are represented drums or windlasses of the peculiar form represented inthe drawings. The center portions of these windlasses are of concave form, as represented at a.. These windlasses, near one end, are formed with ratchet-teeth, (represented at 11,) adapted l At 'i is represented grapplingtongs of one lof thevusual forms of such implements, consisting of the bars 7c, pivoted to each other, as` at l,in the usual manner. The free ends of these'arms,

as at m, are of proper form to span and grasp the head of the rail, and "their lever-arms, as at n, are connected to the free end of the chain byme'ans of links 0, forming a grapple of proper form to grasp thehead of the rait. In the drawings this chain and grapple isonly shown on the drum E; but it is designed to use a like chain and grapple on theidrum` F, in the same manner as shown on thedrum E, but is not shown, as its position would be immediately behind the post of the frame.

At H are represented bars, which connect the posts toward their upper ends on each side of the frame. about the center of their length by means of a transverse bar,I, securely ii Xed to thelugthwise bars H.

At K ar'e represented braces of suitable dimensions, placed in the lengthwise inner angle formed by the posts and sill, and are securely fixed thereto for the purpose of givingfirmness to the parts.

At L are represented spring-pawls of bar form, having a foot portion, o, securely fixed to the sill of 'the frame, and their free upper ends are made in hook form, as at p, `adapted to engage the ratchet-teeth c, to hold the windlasses.

At M isrepresented a vertical shaft, of suitable dimensions, mounted to revolve in a footbearing in the sill, and near its upper end in a suitable bearing in the transverse bar I.

At s are represented chains, which connect the spriug-pawls to the vertical shaft in such a Vmanner that in. the turning of the shaft the chain will be wound thereon,which action will disengage the springs from the ratchets. The upper end of this vertical shaft is of rectangu lar form, as at t, fitted to enter the hole t,formed in the levers to receive it, by means of which the shaft may be rotated to disengage thepawls.

At N are represented the operating-levers, which are suitably curved, and are provided with a hook, u, fitted to engage the -ratchet teeth b, in the manner clearly shown in the drawings. i

With these several parts constructed and arranged as shown and described, the operation of onrinachine is as follows: The machine is placed between the rails crosswise ot' the track, and between the sills or ties thereof.

The grapples are then placed to engage the rails on both sides. The levers are/then employed in the manner represented in the draw ings, and as hereinbefore described, by means of which the operators will be enabled to rotate the windlasses, which action will wind the chain thereon, and will lift the track on one or both sides, as the levers of one or both sides are operated, and when raised will be heldin their raised position by means of the spring-pawl's engagingtheratchet-teeth5 and wh'enthetrack .is properly adjusted the jack is disengaged by removing.;` the levers vfrom the ratchets and placing one of them on the vertical shaft, t'o be employed as a sweep-wrench to disengage kthe spring-pawls, to permit both the windlasses to 'revolve at once, and permit both rails to drop at the same time.

At Pare represented clasps, fixed to the inner sides of the posts on di'agonal'opposite cor ner-posts o'f the frame, in position to receive the handle end of the operating-levers, as seen in the dotted lines, in which position their pro,- jeeting ends will serve 'as handles by means of which the machine may be readily moved from place to place, as required.

.ratchet-teeth of the windlas'ses on opposite sides of the frame, and of springpawls to engage the ratchet-teeth of the windlasses, substantially as and for the purpose hercinb'ei'ore set forth.

2. The combination, with the spring-pawls,

of a winding-shaft and*chain-connection, substantially as and for the purpose hereinbefore set forth.
