SPIKE-FULLER.

SPECIFICATION forming part of Letters Patent No. 642,11 1, dated January 30, 1900.

Application filed May 27, 1899. Serial No. 718,606. (No model.)

To CbZ Z whom it may concern.-

Be it known that I, JOHN D. GREEN, a citizen of the United States, residing at the city of Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Spike-Pullers, of which the following is a specification.

This invention relates to spikepullers for railways. This spike-puller is specially intended for use between rails, such as guardrails or in angles of frogs, where it is impossible to reach and engage the spike with the usual claws.

One object of this invention is to provide an improved spike-puller in which movable jaws engage the opposite sides of the head of the spike automatically and securely.

A further object is to simplify the construc tion of spike-pullers having movable jaws.

Still further objects will definitely appear in the detailed description to follow.

I accomplish these objects of, my invention by the devices and means described in this specification.

The invention is definitely pointed out in the claims.

The structure is fully illustrated in the accompanying drawings, forming a part of this specification, in which- Figure 1 is a detail view of my improved spikepuller in operation, the spike being shown in dotted lines. Fig. 2 is an enlarged detail sectional view of the same, taken on a line corresponding to line'2 2 of Fig. 3, the movable jaw and pin for supporting the same being shown in full lines. Fig. 3 is a transverse detail sectional view taken on a line corresponding to line 3 3 of Fig. 2.

In the drawings all the sectional views are taken looking in the direction of the little arrows at the ends of the section-lines, and similar letters of reference refer to similar parts throughout the several views.

Referring to the lettered parts of the drawings, A is the handle or lever. Bis the heel or portion of the lever on which it fulcrums. This extends into a straight jaw E. An opposite jaw D, hook-shaped, is provided on an auxiliary lever-pieee C. This auxiliary piece 0 has a web 0 projecting into a groove or mortise I in the lower end of the bar A. A

pin G is passed through an elongated slot II to retain the samein position. Acoiled spring F is inserted in the lever A and exerts pressure outwardly on the upper end of the auxiliary lever O. The auxiliary lever O is curved toward the lower end and adapted to rest against a corresponding portion J of the main lever as a fulcrum.

In use my improved spike-puller is reached in between the rails and the jaw D engaged upon the fartherside of the spike to be drawn. Then the opposite jaw E is pushed up on the near side of the spike and the lever A is operated by pulling down. This action causes both jaws to engage the spike with a firm grip. The auxiliary lever O, fulcruming at J on the main lever, holds the jaw D in an unyielding position, which retains its hold upon the spike until it is drawn out.

The jaw D projects a little below the jaw E for convenience in engaging the spike. It also in this position serves practically to engage the spike evenly during the full distance for which it is drawn. The web 0, containing the slot, facilitates the adjustment of the jaws to the spike, so that the jaws will socurely engage any spike within the limits of the size of the implement.

I desire to state that my improved spikepuller can be considerably varied in its details without departing from my invention. A different form of spring than the coiled spring F might be employed, and by careful manipulation with the finger no spring at all would be needed in this position. It is obvious that for spikes of even size the hole H in the web 0' need not be a slot.

The structure will be found effective for pulling spikes in the usual manner, though, as I have stated, it is designed to be especially effective in pulling spikes in a confined space between the rails.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a spike-puller, the combination of the main lever A, with a heel B, thereon, having a jaw E, at its forward portion and containing a longitudinal mortise-slot I, on its front side; an auxiliary lever 0, formed into a hooked jaw D, at its front and adapted to fulcrum on the main lever and having a web 0', to project into the mortise I, the said Web containing a suitable longitudinal slot H; a pin G, through said slot; and a spring F, to throw said auxiliary lever normally into engagement with the main lever to permit its easy adjustment, all coacting together substantially as described, for the purpose specified.

2. In a spike-puller, the combination of a main lever having a jaw at its lower end; an auxiliary lever with a hooked jaw at its lower end located opposite the jaw on the main 1ever, the said auxiliary lever being adapted to fulcrum against the main lever and containing a longitudinal slot; a pin through said slot connecting the auxiliary lever to the main lever, coacting as specified.

3. In a spike-puller, the combination of a main lever having a jaw at its lower end; an auxiliary lever with a hooked jaw at its lower end located opposite the jaw on the main lever, the said auxiliary lever being adapted to fulcrum against the main lever and containing a longitudinal slot; a pin through said slot connecting the auxiliary lever to the main lever; a spring between said levers to hold them in engaging position, eoacting as specified.

In witness whereof I have hereunto set my hand and seal in the presence of two witnesses.
