JOHN H. MORGAN, OF LEBANON, INDIANA, ASSIGNOR OF ONE-HALF TO ELBERT N. WYCOFF, OF SAME PLACE.

SHACKLE CLAW-BAR.

SPECIFICATION forming part of Letters Patent No. 438,083, dated October '7, 1890,

Application filed January 11, 1890- Serial No. 336,702. (No model.)

To all whom it may concern:

Be it known that I, JOHN H. MORGAN, of Lebanon, in the county of Boone and State of Indiana, have invented a new and Improved Shackle Claw-Bar, of which the following is a full, clear, and exact description.

My invention relates to improvements in shackle claw-bars; and the object of my invention is to provide a simple, efficient, and convenient device for drawing spikes, and also to provide a reversible bar that may be used in many positions, that may be used in safety, and that will not slip from the spike.

My invention is especially adapted to railroad-work, and I have so shown it in the accompanying drawings.

To this end my invention consists of a clawbar having a two-armed hook or shackle provided with a suitable claw pivoted to the clawbar near the lower end thereof in such a manner that the hook or shackle may be swung beneath the end of the claw-bar, so as to operate upon the front or back side thereof, as desired.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding part-s in all the figures.

Figure 1 is a side elevation of the claw-bar as applied to a railroad-spike; Fig. 2, a side elevation of the hook or shackle detached from the claw-bar, and Fig. 3 an inverted plan of the same.

The claw-bar A is substantially like an ordinary claw-bar, consisting of a long bar having its lower end terminating in a curved hook or claw a, split in the usual manner to engage the head of a spike.

The shackle Bis provided with two par allel arms I) b, which clasp the lower end of the claw-bar A and are pivoted thereto by a bolt d, which passes through the ends of the arms and through the claw-bar. The arms I) b are united near the outer end thereof and form a curved hook e, which terminates in a claw, so that the shackle serves the double purpose of shackle and claw-hook.

The claw-bar is usually applied as shown in the drawings. The claw a of the claw-bar is placed upon a railroad-tie C so that the claw a will engage the head of a spikef, by which the rail D is fastened to the tie. The shackle B is placed over the top of the rail D, thus holding the claw-bar securely in place,- and the operator then presses backwardly upon the claw-bar A, which will turn upon the pivot d and upon its rounded lower end and thus Withdraw the spikef from the tie.

It will be seen, too, that in certain positions the claw of the shackle 13 might be engaged with a spike and the end of the claw-bar A placed upon a rail or'other raised object and the spike withdrawn by lifting upon the handle of the claw-bar, or the shackle may swing to the back side of the claw-bar and the clawbar used independently.

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

A shackle claw-bar consisting, essentially, of a claw-bar having a shackle or hook pivoted near the lower end thereof, said shackle or hook having its end terminating in a claw adapted to engage a rail or other projection and hold the claw-bar in engagement with a spike or similar object, and having its sides composed of parallel arms pivoted at the ends to the claw-bar, whereby said shackle may be swung below the end of the claw-bar'and to the back side thereof, substantially as de- 80 scribed, and for the purpose specified.

JOHN H. MORGAN.
