AROHIBALD R. WYGLE, OF KINGMAN, KANSAS.

CLAW- SPECIPICATION forming part of Letters Application filed September l, 1887.

To all whom it may concern Be it known that I, AROHIBALD R.WYGLE, a citizen of the United States of America, residing at Kingmanfin the county of Kingman and State of Kansas,have invented certain new and useful Improvements in Claw-Bars; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon,which form a part ofthis speci fication.

My invention relates to certain new and useful improvements in claw-bars or spikepullers, the object of my invention being to provide a simple, cheap, and strong claw-bar having movable jaws, which are expansible from each other, and which will be brought together and clamped upon a spike or other object when the handle is depressed; and my invention consists in the construction and com bination of the parts, as will be hereinafter fully set forth, and specifically pointed out in the claims.

In the accompanying drawings,whieh illustrate my invention, Figure l is a perspective view of a claw-bar constructed in accordance with my invention, showing the same applied in position for use. Fig. 2 is a sectional-view taken through the lower end of the handle and through the pivoted claws on a line with the connecting-bolt. Fig. 3 is a detail perspective view of the lower end of the handlebar, showing one of the claws removed there from; and Fig. 4 is a detail perspective View of one of the claws.

A refers to the handle of my improved clawbar, the upper end of which is of ordinary construction, while the lower end has formed integral therewith a depending portion, B, upon which are formed shoulders I) b, which have openings, through which passes a connectingbolt. The front lower end of the clawbar is curved above the shoulders, as shown at C, while the rear portion is cut away at an angle and is provided centrally with a dependingV or wedge shaped portion, 1), which is located on the end of the rear portion of the handle rear of the perforations, through which BAR.

Serial No. 248,510. (No model.)

the bolt passes, and said wedge-shaped portion D is formed integral with the portion B. The rear lower portion of the curved bar is curved outwardly, as shown. The lower end of the handle-barA is provided near its heel or lower end with a transverse perforation, through which passes a spring-bar, said spring-bar abutting against stop-pins c, which pro ect from the sides of the handle, as shown.

The claws E E are similar in construction and are provided with sockets b, which are adapted to fit over the circular shoulders b, formed on the handle A. These claws are also provided adjacent to the socket b with semicircular recesses B, which will fit over the curved portion B of the handle. The front projecting portion, F, of the pivoted claws are serrated, so as to better grasp the spike or other object which may be placed between said jaws, and the lower portions of these jaws are curved, as shown. The rear portions of the jaws are provided with stops G and G', the front stop, G, being adapted to abut against the straight portion 9 at the front lower end of the handle, so as to limit the movement of the claws upon the pivot in one direction, while movement in the opposite direction 1s prevented by the shoulder G-contacting with the straight-inclined portions 9, formed on the handle-baradjacenttothewedgeD. Theinner edges of the claw-bar adjacent to the portion G are slightly beveled, as shown at h. The jaws E E are pivoted to the lower portlon of the handlebar by a bolt, I, and adjacent to the sides of the claw-bars, through which this bolt passes, are placed rubber or spring washers K K, above which may be placed ordinary metallic washers. permit the claw'bars to have a slight lateral movement upon the bolt without straining the same, and, as the sockets in the claw-bars fit snugly over the shoulders and projecting portions formed on the end of the handlebar, the strain will not come upon the bolt.

L refers to aspring-bar, which passes through the perforation d in the handlebar and beneath the projecting pin 0, the terminal portions of this spring-bar being bent so as to engage with pins m, attached near the heels of the claw-bars, said spring having a tendency to throw the claw-bars up so that they will be These spring-washers will substantially at right angles with the handle, the front ends being thrown wide apart.

When the jaws are placed over a bolt or other object and the handle depressed, the wedge-shaped portion D, formed integral with the handle and rear of the pivot which serves as a fulcrum for the handle, will pass between the heels of the jaws, so as to separate them and close the front ends of the jaw upon the bolt or spike, and as the handle is depressed the front end ofthe jaws will be elevated, so as to withdraw the bolt.

The portions 1) B, hereinbefore referred to, form laterally-extending bearings when they enter the sockets b B in the. jaws and relieve the bolt from a greater portion of the strain, and their laterally-extending portions form a direct fulcrum for the handle. The wedgeshaped portion D being a considerable distance from the bolt or centerof the movement of the handle can be powerfully pressed between the heels of thejaws with little exertion.

I am aware that'prior to niyinvention it has been proposed to provide claw-bars with jaws which are pivotally secured to a handle, so

. that when the handle is moved rearwardly the jaws will be brought together, and I do not claim such construction, broadly; but

Vhat I claim as'new, and desire to secure by Letters Patent, is-

1. A claw-bar consisting of a handle, said handle having formed on its lower end laterally-extending bearings or projecting portions 1) B, through which pass a pivot-bolt, a wedge formed on said handle in the rear of said bear-' ings,and j aws attached to saidhandle bythe pi vot-bolt, so that the wedge formed on the handle will be passed between the heels of the pivoted jaws, so as to bring the points together when the handle is moved rearwardly, upon its pivot, substantially as shown, and for the purpose set forth.

2. The combination, in a claw bar, of a handle provided at its lower end on opposite sides with laterally projecting bearings or projecting portions b B, having a perforation through which passes a bolt, the wedgeshaped portion formed on the lower end of the handle rear of the bearings, jaws havingre cesses within which the bearin gs formed on the handle lie, the heels of said jaws being tapered, so that the point of the wedge will lie between the same, and a bolt for connecting the jaws to the handle, substantially as described.

3. In' a claw-bar,ahandle, A, provided at its lower end with a shoulder-bearing, a wedge, D, formed integral with the handles above and rear of the bearing, jaws E E, having recesses adapted to lie over the shouldered bearings, a bolt for connecting the jaws pivotally to the handle, and compressible washers interposed between the jaws and head and nut of the bolt, the parts being combined substantially as shown, and for the purpose set forth.

4. The combination, in a claw bar, of a handle provided at its lower end with a depending portion, B, having shoulders I) b, a wedge-shaped depending portion, D, formed integral with the portion B and the handle, claws having sockets, and a belt for pivotally securing said claws to the handle, substantially as shown, and for the purpose set forth.

5. The combination, in a claw bar, of a handle provided at its *lower portion with means for pivotally securing thereto claws, said handle-bar also being provided with a wedge-shaped portion, D, and shoulders g and gf, against which shoulders stops formed on the claw-bars are adapted to abut, substantially as and for the purpose specified.

6. The combination, witha handle, ofaclawbar having shoulders 91 g, a depending portion with circular shoulders 1) formed thereon, and a wedgeshaped portion, D, claws E E, having sockets adapted to fit over the shoulders b b, a bolt for securing the parts to each other, and aspring attached to thelower end of the handlebar, so as to exert a downward springpressure upon the heels of the claws, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
