STAPLE-PULLER.

IilIECJIlCATION forming part of Letters Patent N o. 722,975, dated March 17, 1 903.

Application filed December 22, 1902. Serial No. 136,173. (N0 model.)

To all zul-1,0177, t may concern:

Be it known that I, GEORGE P. HALEY, a citizen of the United States, anda resident of Mexico, in the county of -Audrain and State of Missouri, have invented a new and lmprved Staple-Puller, ot` which the following is a full, clear, and exact description.

The object of'v the invention is to provide a device for drawing staples from the posts or other supports for fence-wirev and to so constructtt-he device that it will not only be simple, havingbut few parts, and strong and readily manipulated, but wherein the device is capable of drawing straight out the longest fence-wire staples and of retaining the drawn staples until purposely removed from the device.

The invention consists in the novel construction and combination. of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference isto be had' to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the improved device. Fig. 2 is a front elevation ofthe same. Fig. 3 is a section taken practically on the line 3 3 of Fig. 1, and Fig. 4 is a section taken on the same line as in Fig. 3 through a slight modification in the lower portion of the grip-lever used in connection with the device.

The shank A is provided with a handle 10 at one end and with a clawhead 1l at the opposite end, including a hammer-section 12. The outer edge 13 of the claw-head, which 'is the lower edge in action, is convexedfand the inner edge 14 of the claw-section of the claw-head, which is the upper edge in action, is straight, as shown in Fig. 1, and said clawsection terminatesin apoint 15. A clamp B is used in conjunction with the claw-head.

This clamp is U-shapedin cross-section and is bifurcated at its inner ends, the shank A being received between the members of the bifurcated section ot said clamp, and the clamp is pivoted to the shank by a pin 16 or its equivalent. The outer end of the clamp is downwardly and outwardly inclined, the inclination being away from the shank and in direction ofthe point ot the claw-head, and

teeth 17 are projected from the loweredge of said clamp at its outer end, the teeth having a corresponding inclination to the inclination of the outer end ot said clamp. The clamp is furtherprovided with a lug 13 upon its upper surface.

A connecting-rod 19 ispivotally attached at one of its ends to the lug 18, and the other end of the connecting-rod is pivoted between the bifurcated lower section 20 of an anglelever 21. The shank A is passed between the members of the bifurcated portion of the lever 21, and the lever is pivoted to the shank on a pin 22, passed through the' bifurcated portion of the lever at a point near the eenter thereof, The upright or grip section of the angle-lever 21 isnormally held at an angle to the shank through the Vmedium of a spring 23, engaging with the-inner face of the said grip-section of the lever and the rear edge of the shank. VThis spring may be a strap-spring, as shown in Fig. 1, orsaid spring may be a coil-spring, as shown in dotted lines at 23a in Fig. 2. The bifurcated or pivoted section of the grip-lever may be constructed as'shown in either Figs. 3 or 4., In either case the said section comprises two parallel members a and a', and in one'instance the inemhers extend parallel and are spaced throughout their length, whereas in-'theother case the outer ends of the members are brought closely together.

In operation the point of the Vclaw-head is introduced beneath theibowsection kof the staple, and the point is driven well beneath said staple by striking the hammer-section of the claw-head, and at the'same time the gripsection of the lever is carriedup close to the handle, bringing the teeth 17 of the `clamp over and at each side of the point ofthe clawhead and the point of the claw-head between the members of said clamp. The shank is then rocked upon the convexed surface 13 of the claw-head, Iwhich surface 'affords sufficient leverage to enable the operator to draw straight out the longest' staple in use on a wire fence, enabling-said staple to be used again. The clamp will hold the staple upon the claw-head as long as the grip-section of the lever is parallel with the handle of the device. Thus the staple will loe prevented from dropping to the ground; but said staple ICO may be freed from the device as soon as the lever 2l is released.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- Y 1. A staple-puller, consisting of a shank provided witha claw-head having a con vexed outer face adapted as a fulcrurn, a clamp pivoted upon the shank and adapted to receive the point of the claw-head, a lever alsopiv-f oted upon the shank, and a connection between the lever and said clamp, for the purpose set forth.

2. In astaple-puller, ashank provided with a claw-head having its outer edge convexed to form afulcrum, a clamp U shaped in crosssection and havinga pivotal attachment to the shank, and extending over the inner edge of the said claw-head, said clamp being provided with teeth at its outer end, a springcontrolled lever also pivoted to the shank adjacent to its handle end, and a rod connection between said lever and said clamp, for the purpose set forth.

3. A staple-puller, consistingof a shank provided with a claw-head including a hammer-section, the outer edge of said claw-head being oonvexed throughout its length, the claw-section of the claw-head terminating in a point, a clamp U-shaped in cross-section, pivoted upon the shank adjacent to the inner face of the claw-section of the claw-head and extending over said section, the outer` edge of said clamp being beveled away from the shank and in direction of the point of the claw-head, the outer end of the clamp being provided with downwardly-extending teeth also having an inclination downwardly in direction of the point of the claw-section of the claw-head, an angle-lever pivoted to said shank adjacent to said handle-section, a spring having bearing against the grip-section of said lever and adjacent edge of the shank, and a connecting-rod pivotally attached to the pivoted member of the anglelever and to the said clamp, for the purpose specified.
