Feb. 13, H w HlNGST STAPLE PULLING TOOL Filed June 10, 1933 Patented Feb. 13, 1934 UNITED STATES PATENT OFFICE 14 k 2 Claims.

This invention relates to the class of tools and pertains particularly to a staple pulling tool.

The primary object of the present invention is to provide an improved form of staple puller in which the ability to obtain a greater leverage is had and the tool may be more firmly located against the body from which the staple is to be drawn so that positive and quick engagement and withdrawal of the staple is assured.

; 1 Another object of the invention is to provide a staple pulling tool having associated therewith as an auxiliary feature, a combination nail puller and wire stretcher so that the tool may be employed in the application of wires to a post or other support.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawing forming part of this specification, with go the understanding, however, that the invention is not confined to any strict conformity with the showing of the drawing but may be changed or modified so long as such changes or modifications mark no material departure from the salient fea- 13 tures of the invention as expressed in the appended claims.

In the drawing:- Figure 1 is a view in side elevation of the tool; Figure 2 is an edge elevation, a portion of the head being broken away;

Figure 3 is a view looking toward the head end of the tool.

Referring now more particularly to the drawing wherein like numerals of reference indicate corresponding parts throughout the several views, the numerals 1 and 2 indicate the handles of the present tool, which are crossed adjacent their ends and pivotally connected together by means of the bolt 3 so that the tool operates in the nature of pliers. The handles 1 and 2 terminate at the ends adjacent the pivot bolt 3, in the heads indicated respectively by the numerals 4 and 5.

The head 4 is formed to provide the elongated pointed jaw 6, the point of which is indicated by the numeral 7. This jaw extends transversely of the longitudinal center of the tool and forms an oblique angle therewith, the point 'I lying adjacent the longitudinal center of the tool as shown in Figure 1.

The head 5 has the terminal jaw portion 8 which is in the form of a broad blade, the free end edge of which has cut therein the two recesses or notches 9 to form a center point 10 and side points 11. This jaw 8 also extends obliquely of the longitudinal center of the tool and is arranged so that the points 7 and 10 of the two jaws will abut in the manner illustrated in Figure 3.

As illustrated, the head 5 is larger than the head 4 and the curved portion thereof describes a larger arc than the arc of the curved portion 430 of the head 4 so that the jaw 8 extends beyond the jaw 6 and curves back to meet the point '7. It will thus be seen that in viewing the tool in side elevation the opposed tips of the jaws are so arranged that the plane in which the same lie is oblique to the longitudinal center of the tool as a whole. By this construction the engagement of a staple is facilitated and by rocking the tool upon the head 5 a longer fulcrum is obtained so that long staples may be easily removed from a post or other body in which they are secured.

Mounted upon the bolt 3 at one side of the tool is an elongated member 12 which is turned back at one end as indicated at 13 to form a hook which is bifurcated to form the two prongs 14. 3:5 This bifurcated or two-pronged hook is designed for use as a nail extractor or for engaging and pulling or stretching a wire so that the latter may be drawn to a taut condition for stapling.

The hook device 13 is rotatably mounted upon the bolt 12 so that in the use of this device for pulling nails or for stretching wire, it may be swung into the position where its operation will be most effective.

From the foregoing it will be readily apparent that the tool embodying the present invention constitutes an eflicient instrument for extracting staples because of the peculiar head construction and the formation of one of the jaws with three prongs so that the staple may be more effectively gripped and withdrawn.

The convenient application of the hook member 13 to the side of the tool enables the user to readily withdraw nails or engage a wire to apply a pull thereto.

Having thus described the invention, what is claimed is:-

1. A tool of the character described, comprising a pair of pivotally connected handles, a head integral with each of said handles adjacent the pivoted end thereof, each of said heads describing a substantial semi-circle and having a free end located substantially upon the longitudinal center line of the tool, the said free ends of the heads being in opposed relation and constituting jaws, one of said jaws being formed to provide a single point, and the other of said jaws being formed to provide a central point opposing said single point and lateral points extending in the same direction as said central point.

other whereby it extends beyond the said other head from the pivotal point for the handles, said last mentioned head being of substantially the same width throughout and terminating in three points, and the other head being formed to provide a single point which opposes the central one of the said three points.

HENRY W. HINGST.
