TRACK-MINER.

Specification of Letters Patent.

Patented July 31, 1906.

Application filed May 19, 1906. Serial No. 317,840.

To aZZ whom it may concern:

Be it known that we, PHILIP WULFF and ERNns'r HAM, citizens of the United States, residing at Argyle, in the county of Osage and State of Missouri, have invented new and useful Improvements in Track-Liners, of which the following is a specification.

This invention relates to an improved track-liner, and has for itsobject to provide a novel device of this description which shall be simple and durable in construction and in the use of which great power may be exerted upon the rails to bring them into alinement.

The invention is illustrated in the accompanying drawings, in which Figure 1i s a view in side elevation of the device, and Fig. 2 is a cross-section of the same.

Referring now to the drawings, the numeral 1 indicates a base,-extending longitudinally of which is a groove 2, o ening on the uplper side of the base. Slidab y'confined in t s groove is a rack-bar 3, adapted to be forced outward into en agement with the rail in the manner to p e described later. Projecting from the forward end of the base 1 is a tongue 4, which is adapted to be inserted under the rail to assist in maintaining the prcziper position of the device when in use, an on the rear end of the base is mounted a downwardly-extending pointed sto bloek 5 which may be driven in the earth a jacent to one of the rails of the track to form a bearing to resist backward movement of the device in forcing the rails into osition. Secured to o posite ends of the ase 1, at each side t ereof, is a curved support 6.

7 indicates a lever which is mounted toward its lower end, as mdicated at 8, in and between the supports 6 and has pivotally mounted at its lower end a pawl 9, which is adapted to engage or rideover the teeth of the rack-bar 3, according as said pawl is moved in one direction'or the other by the lever 7. Y i v 10 indicates a lever-arm which is pivotally mounted at its lower end in and between the supports 6 at the opposite end of said support to which the lever 7 is secured.

11 indicates a connectin bar which is bifurcated at its opposite on s to embrace the lever 7 and lever-arm 10, respectively, and is pivotally secured, as indicated at 12, to the outer end of the lever 7 and, as indicated at 13, to the lever-arm 10 toward the lower end thereof.

pivotally Pivotally mounted in and between the supports 6, at the rear side thereof, is a gravity-pawl 14, which rests upon the teeth of the rack-bar 3 and operates to hold said rack-bar to any position to which it may beforced while operating the lever-arm 10.

In the operation of the device as the leverarm 10 is moved forward or toward the front end of the device the pawl 9 will be moved to the rear and will ride over one or more teeth of the rack-bar 3 to a new position on said rack-bar. When the lever-arm 10 is moved backward, the pawl 9 will be moved forward, thereby forcing the rack-bar 3 outward. The above 0 erations may be rapidly repeated, the paw 14 operating to hold the rack-bar to its adjusted position, as above, stated. By means of the connecting-bar 11 pivoted to the respective members 7 and 10, as scribed, we are enabled to obtain a large increased power over what would result from operating the lever 7 directly.

We claim 1. A track-liner comprising a base having su ports mounted thereon, a rack-bar slidably mounted in said base, a gravity-pawl mounted in said supports for normally engaging said rack-bar, a lever 'pivoted intermediate its ends in said supports and carrying at its lower end a paw or engaging the teeth of said rack-bar, a lever-arm pivotally mounted at its lower end in said su ports, and a connecting-bar pivotally secure at opposite ends, respectively, to the outer end of said lever and toward the lower end of said lever-arm.

2. A track-liner com rising a base, a forwardly and downwardly projectin tongue located at the forward end of sai base, a stop-block mounted at the rear end of said base, a rack-bar slidably mounted at its base, supports secured to said base, a gravity-pawl pivotally mounted in said supports and adapted to normally engage the teeth of said rack-bar, and means mounted on said supports for moving the rack-bar outward in one direction.

In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.

PHILIP WULFF. ERNEST HAM.

Witnesses: JOHN BAUMBOER, AUG. BORGMEYER.
