IMPROVEMENT IN SPIKE-DRAWER.

it The Schedule referred to in these Letters Patent and'making partof the same To all whom it may concern:

.Be it known that I, B N AMIN B. Wool), of Negaunee, in the county of' Marquette andState of Michigan, have invented a new and useful Imprm'ej'm'eht in Spike-Drawers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing forming part ofthis specification, and in which Figurel represents aview in perspective of a spike drawer constructed in accordance with my improvement, and Q Figure 2,a longitudinal section of the same, in part,

showing the manner inwhich its clawend is introdnced under the head of thespike to draw the latter;

and Figure 3, a. similar riew,indioating theposition of thedevice when completingit-s drawing action.

Simila1" letters-of reference indicate corresponding parts.

My improvement consists in a claw-bar or instruwj ment of improved construction for drawing railroad. and other spikes without injuring or impairing them by bending for future use.

Referring to the accompanying drawing, the clawbar or instrument there represented is formed at its 1 one end with a chisel-shaped nose, a, for indenting the 1 wood or surface under the head of the spike, to make room for the introduction of the opposite or claw-end of the bar. This latter end, which forms a movable the upper or outer end of the claw, with a cavity, 0, i

made therein. This slot 0 should be of snfiic'eint width to receive withinit the body of the spike, but not allowing of its head to pass therethrough.

Room having been made by the chisel-end a for insertionoi' the claw under the head of the spike, the latter is applied, as represented in fig. 2, seas to introduce the inner edges of the sides d (Z of the slot c, lying within the cavity 0, under the head of the spike, to start the latter. The tool is then kept pushed up toward the spike, and borne or worked downward at itsback end,causing it to slide on its rounded or fulcrum portion, until, as the drawing proceeds, the outer ends of the claw bear under the head 'of the spike, as represented in fig. 3, said spike, by. the construction and action of the. claw, as described, being drawn straight, or nearly so. I

I am familiar with the patent, No. 37,172, dated December 16, 1862, for a somewhat similar device, but differing in some particulars from my invention. This therefore I do not claim; but

What is here claimed, and desired to be secured by Letters Patent, is-

' The spike-drawer, formed at its one end, I), and slotted, as at c, to constitute a claw, having sides, dd, of diminishing depth from a cavity, e, in the outer end of -the claw, and with a chisel-point, a, at its opposite end, substantially as shown and described, for

the purposes set forth. 1
