DRIFT-BOLT OR RAlLROAD-TRACK-SPIKE DRAWER.

SPECIFICATION forming part of Letters Patent No. 556,469, dated March 17, I896. Applioation filed July 29, 1895. Serial No. 557,494: (No medal.)

To all whom it may concern:

Be it known that I, HOWELL N. LEWIS, a citizen of the United States,residing at Green Cove Springs, in the county of Clay and State of Florida, have invented a new and useful Oombination Tool for Drawing Drift-Bolts or Ship and RailroacbTrack Spikes, of which the following is a specification.

This invention relates to certain new and useful improvements in tools for drawing bolts on railroads or for bridgework, it being specially adapted for drawing spikes on rail roads and for drawing drift-bolts of any size, as the tool is self-adjusting.

The object of my improvement as a clawbar for railroad use is to enable the operator to draw out track-spikes from a position outside of the inside track, and especially for use on high bridges where the operator cannot work with safety from the outside of the track.

To these ends and to such others as the invention may pertain the same consists further in the novel construction, combination, and adaptation of the parts, as will be hereinafter more fully described and then specifically defined in the appended claims.

1 clearly illustrate my invention in the accompanyin g drawings, which, with the letters of reference marked thereon, form a part of this specification, and in which drawings similar letters of reference indicate like parts throughout both views, in which Figure 1 is a view of the tool, the sleeve down at its lowest limit locking the shoe at its greatest tilting limit. Fig. 2 is a view of the tool with the sleeve locking the shoe against the back of the operating-lever.

Reference now being had to the details of the drawings by letter, A designates the shoe of the tool, which is provided witha claw end, and is recessed a portion of its length and between the walls of which recess is pivoted the lever B, the lower end of which is tapered to an edge, which is designed to bite against the edge formed by the curved surface of the shoe and the front wall of the said recess. An aperture g is provided in the said shoe, which is designed to receive spikes or bolts, and the sharp edges at the ends of the front and rear walls of the said aperture to engage with the opposite sides of a spike which is to be withdrawn.

Mounted so as to slide on the lever B is a slide 01 provided with a thumb-screw to lock the slide to a given position on the lever, and the lower end of the said slide is recessed away, forming the extension f, which, when the slide is lowered down, engages with and locks the shoe in the position shown in Fig. 3, and when the slide is raised to the height shown in Fig. 4 it is in a position to lock the shoe so that its heel will rest against the back of the lever B.

From the foregoing it will be seen that the tool may be readily and quickly adjusted for use to draw spikes or bolts or spikes in various positions and of various lengths.

What I claim to be new, and desire to secure by Letters Patent, is-

1. A tool for drawing bolts andspikes consisting of the shoe having an aperture 9 having its upper and lower walls brought to sharp edges, combined with a lever B pivoted in a recess of the shoe and means for holding the shoe in different positions, substantially as shown and described.

2. Atool for drawing bolts and spikes consisting of a shoe having a recess between the walls of which is a pivoted lever B, combined with a slide D having a recessed portion on its inner lower edge, which is adapted to lock the said shoe tilted at different angles, substantially as shown and described.
