EDWVARD HANKING, OF BATESVILLE, INDIANA.
\ STAPLE-FULLER.
Specification of Letters Patent.
Patented Dec. 18, 1906.
Application filed April 4, 1905. Serial No. 253,866.
To all whom it may concern.-
Be it known that I, EDWARD HANKING, a citizen of the United States, residing at Batesville, in the county of Ripley, State of Indiana, have invented certain new and useful Improvements in Staple-Pullers 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.
This invention relates to staple-pullers, and more particularly to a tool es ecially adapted for the withdrawing of stap es used in wire-fence building, the pulling out of nails and spikes, the opening of barrels and boxes, and the stretching of barbed fence-wire.
One object of the invention is to provide an exceedingly simple, inexpensive, durable, and efficient tool or device of the character stated.
Another object of the invention resides in the provision of a tool for the purposes stated wherein but two elements are involved and wherein an increased or decreased leverage may be had, as desired, the means for permitting the increase or decrease in leverage being so associated with the device as to insure positiveness with respect to the positioning of one element of the device relative to the other.
With these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the present invention.
In the drawings, Figure 1 is a perspective view of the complete tool as disposed for use. Fig. 2 is a vertical sectional view through the device, and Fig. 3 is a plan view of the fulcrum.
Referring now more particularly to the accompanying drawings, the reference charac ter 1 designates a lever having a head 2 at one end and its opposite end enlarged and tapered upon opposite sides and bifurcated, as at 4, to form a claw.
Mounted for sliding movement upon the lever is a fulcrum-block 5, preferably of disk shape, with its periphery provided with teeth 6. By reason of the enlargement of the lever at one end and the head at the other end this disk-shaped fulcrum, which has a central perforation embracing the lever, is prevented from leaving the latter. the teeth 6 of the fulcrum should become worn or broken, the fulcrum could be rotated upon the lever to present other teeth to a surface in the use of the device. The opposite flat faces of the fulcrum 5 are beveled toward each other at the said central perforation to form a sharp circumferential edge 7 designed to engage the notches 8 and 9, arranged, respectively, upon opposite sides of the lever.
From the foregoing it will be understood that in the use of the tool the claw thereof is enga ed with the wire, staple, spike, nail, or the like and the fulcrum is shifted toward the claw in engagement with the notches 8 and 9, in which the sharp edge of the fulcrum engages to prevent its slipping when the lever requires a fulcrum for the purpose of withdrawing any one of the elements just recited. By reason of the peculiar formation of my improved fulcrum and its association with the notches in the lever it is obvious that the circumferential edge of the central opening thereof will engage andbind the tool within the notches while the teeth arranged upon the periphery of the fulcrum will tend to bite into the material adjacent the elements to be withdrawn and prevent slipping of the fulcrum.
What is claimed is 1. A device of the class described comprising a notched lever having a claw end, and an annular fulcrum engaged upon the lever, said fulcrum having its inner periphery beveled in opposite directions from its flat faces to form an annular rib for engagement in said notches.
2. A device of the class described comprising a notched lever having a claw end, and an annular fulcrum engaged upon the lever, said fulcrum having its inner periphery beveled in opposite directions to form an annular rib for engagement in said notches.
In testimony whereof I affix my signature in presence of two witnesses.
EDWARD HANKING.
