COMBINED LlFTlNG-JAC K AND TRACK-LINER.

' SPECIFICATION forming part of Letters Patent No: 541,002, dated June 1 1, 1895.

Application filed January 22, 1895. Serial No. 535,778. (No model.)

T0 at whom it may concern.-

Be it known that we, THOMAS MOMANUS and GEORGE K. SMART, both of Atchison, in the county of Atchisonand State of Kansas, have invented a new and Improved Combined Lifting-Jack and Track-Liner, of which the following is a full, clear, and exact descriptiou.

The invention relates to railroad implements; and its object is to provide a new and combined lifting jack and track liner, which is comparatively simple, light, economical and durable in construction, and arranged for conveniently and rapidly raising the track or shifting the same sidewise,without injury the track-bed or track.

The invention consists principally of a horizontal base or lining bar, a hollowpost or bar with or without roller bearings fitted to slide thereon, and a lifting bar fitted to slide in the post and adapted to support the rail.

The invention also consists of certain parts and details and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings, formingapart of this specification, in which similar letters of reference indicate corresponding partsin all the figures.

Figure l is a perspective viewof the improvement as applied, showing the employment of two jacks and track-liners. Fig. 2 is a sectional perspective view of the improvement with the device for lifting the post omitted, and also the lifting-lever. Fig. 3 is a perspective view of the post-shifting device. Fig.4 is a sectional side elevation of the same, andFig. 5 is a perspective view of the reciprocating ram. v

The improved lifting jack and track liner is provided with a base or lining bar A, preferably made. of metal and T-shaped in form, and having the vertical member A, provided with a base plate B, for supporting the lining bar on the track bed.

A horizontal member A forms guideways for the lower sliding part 0 of a post O,.like-' wise made of metal and hollow, and fitted to slide on the horizontal member A of the lining bar. Suitable roller bearings may be employed between the post and member A In this hollow post 0 is fitted to slide vertically,

the lifting bar D, also made hollow and square in cross section, one side being provided with a foot D, projectingthrough a slot 0 formed in the adjacent side of the post 0. This projecting foot D'is adapted to support the base of a rail to shift or lift the latter, as hereinafter more fully described.

On the inside of the lifting bar D, on the side carrying the foot D, are ratchet teeth D engaged by a spring-pressed pawl E, set with its pivot end in a recess F, formed in the lifting ram F, fitted to slide vertically within the lifting bar D, as is plainly indicated in Fig. 2. In the upper end of this ram F is arranged a transverse opening F adapted to be engaged by a transverse bearing G on the end of a lever G having its fulcrum G in bearings 0 formed integral with the upper end of the post 0. Now, it will be seen that by the operator swinging the lever G up and down, a reciprocating motion is given to the ram F, so that the pawl E, carried by the said ram and engaging the teeth D lifts the lifting bar D within the post 0, so as to raise the rail supported on the foot D.

In order to hold the lifting bar in position after it is raised, on the upward sliding movement of the ram F, a supporting pawl H is provided having its fulcrum H in a seat C forming part of the post 0, and arranged at the lower inner side thereof, as plainly indicated in the drawings.

The supporting pawl II is pivotally connected at its upper end with a rod H extending through the open side of the lifting bar D, and through a slot on the inner side of the post 0, the outer end of this rod H being pivotally connected with a cam I, having a handle I, and adapted to abut against the outer face of the inner side of the post 0, so that the operator, on moving the handle I upward, exerts a pull on the rod H to lift the supporting pawl H out of contact with the teeth D to permit the lifting bar D to descend, when it is desired to lower the rail and track. A rod may be employed to connect the handle I with the lever G for pulling the device out of gear to release the supporting The pawl H is provided with an upper extension H adapted to engage the lifting pawl E, so that when the rod H is pulled outward and the pawl H moves out of engagement with the teeth D then the extension II at the same time engages the pawl E and swings the latter outof engagement with the teeth D.

In order to hold the rail in position on the foot Dof the lifting bar, a hook J is pivoted on the front of the post 0, as indicated at the right in Fig. 1.

In order to shift the post 0 on the lining bar A to move the rails and track ties sidewise, the following device is provided, particular reference being had to Figs. 3 and 4.

A plate K, extending over the inner part of the horizontal member A is adapted to be fastened by a pin K, to the lower end 0" of the post 0. The outer end of this plate K is formed with a forked head K carrying a transverse pivot pin K on which are held guideways L, engaging the side edges of the horizontal member A of the lining bar A, to hold the plate K in proper position on the member A but to permit a sliding movement thereon.

On the pivot pin K is fulerumed a lever N under the control of the operator, and carrying two pawls O and P, located one above the other, and each being pressed on at its pivoted end by a spring 0' or P respectively. The pawls O and Pare fulcrumed in the head N of the lever N, as is plainly shown in Fig. 4, and the pawls are of different lengths and are adapted to engage with their free ends, teeth A formed in the upper surface of the horizontal member A The longer and uppermost pawl O is provided at its pivot end, with an upwardly extending handle 0 adapted to be taken hold of by the operator, to throw the said pawl out of mesh with the teeth A whenever it is desired. The lower and shorter pawl P is-connected by a link P with a hook P adapted to be hooked onto the projection N of the lever N, to throw the pawl P out of engagement with the teeth A In the front end of the plate K is arranged a catch K adapted to be moved in and out of engagement with the teeth A by a handle K connected with the catch, and having its bearing in the plate K, as indicated in Fig. 3. The catch K is moved out of engagement with the teeth A whenever it is desired to use both pawls O and P at the same time. hen it is desired to use but the pawl P then the catch K is moved in engagement with the teeth A for the purpose of holding the bar in position while taking the backward movement with the pawl P.

For very heavy tracks, it is advisable to employ two lifting jacks and track liners, as indicated in Fig. 1, the said jacks being connected with each other by a chain Q, hooked on a hook R, secured on the post C of the jack on one side, the other end of the chain being connected with the pivot pin K of the plate K, fastened to the post 0 of the other track liner. Now, it will be seen that in manipulating the lever N, that is, in moving it up or down, the pawl O or P, or both, imparts a sliding motion to the plate K, so as to shift the post 0 and the rail supported thereon sidewise, until the railsare in the proper position.

It will be seen that by the construction described, a single machine only, is required to lift the rails and ties by moving the same sidewise until the proper position is obtained, itbeing understood that the lining bar'or base A is placed between two adjacent ties on the railroad bed, and the levers G and N are manipulated as set forth, to either raise the rails and ties, or to shift the same sidewise.

\Vhen one lining bar and jack is used the chain is provided with clamps to connect the opposite rails to said lining bar. These clamps by being placed close together give greatest length of chain when placing the shorter ends farther apart.

Having thus fully described our invention, we claim as new and'desire to secure by Letters Patent- 7 1.
