Application January 3, 1939, Serial No. 249,014 7 (01. 30-175 1 Claim.

My invention relates to new and useful improvements in cobblers tools.

' An important object of my invention is the provision of an implement for clipping and/or pulling nails and the like.

A further important object of my invention is the provision of an implement of the above character particularly adapted for use in connection with the manufacture or repair of shoes whereby the person operating the same may more expeditiously and efiiciently clip or pull nails or pegs used in conjunction with such manufacture or repair of shoes.

A still further important object of my invention is the provision of a tool of the above character which is simple and sturdy of construction, cheap of manufacture and eiiicient in operation.

While my invention as above indicated is particularly adapted for use in connection with the manufacture or repair of shoes, it will be readily understood that the possibilities for use of the same are unlimited.

In the accompanying drawing forming a part of this application and in which like reference characters are employed to designate like thoughts throughout the same- Figure 1 is a top plan view of my invention,

Figure 2 is a side elevation of the same,

Figure 3 is a sectional view on the lines 3--3 of Figure 1, and

Figure 4 is a detailed plan view of the elements of my invention. I

In the drawing, wherein for the purpose of illustration is shown a preferred embodiment of my invention, it will be noted that my tool is composed of two principal parts each having a handle I, a body 2 and a jaw or gripping member 3. These two'principal parts or elements are pivotally joined through the respective body portions 2 by the rivet or pin 4' extending through the apertures 5. The rivet or pivot pin may be countersunk within the recesses 6 and l as better illustrated in Figures 3 and 4.

The respective body portions 2 are oppositely offset as shown at 8 and 9 whereby the jaws or gripping members 3 may engage along a meeting line Ill defined and constituted by the inner jaw edges, when the jaws are actuated by the handles to the position as shown in Figure 1.

' The relatively outer sides of the jaws 3 are each curved inwardly in plan, sothat when the jaws are juxtaposed they extend to and terminate in a point I l as viewed in Fig. 2. Thejaw sides are also curved downwardly to the meeting line In which latter is pitched or upwardly inclined to thehorizontal as at l2, also indicated in Fig. 2, to intersect the plane of the top jaw surfaces generally at the pointed end I l which constitutes the tool point. The relatively inner sides or faces of the jaws are inclined outwardly of the meeting edges [0 thereof and rearwardly of the pointed end II to provide, when the jaws are juxtaposed, a pyramidal recess, one corner edge of which is constituted by the meeting line In, and theapex of which when the recess is viewed in plan as in Fig. 1 is spaced a slight distance rearwardly of the tool point H. The adjacent inner edges of the jaws, which provide the meeting line H], as aforesaid, bear cutting edges which. are thus pitched or inclined to the horizontal, the jaw recess providing a nailor peg-head receiving cavity which is progressively larger in the direction of its base.

Disposed adjacently on the relatively inner faces of the jaws are complemental notches I3, which when the jaws are juxtaposed register to provide a generally vertically disposed aperture adapted to receive the shank of the nail or peg to be pulled. Said notches which as shown are each generally triangular in shape so as to form, when brought in registry, a constricted opening are tapered inwardly, thus to accommodate nail shanks of varying sizes. Moreover, the tapering of the notches forming the gripping opening cooperates with the conical shanks of cobbler-s nails themselves so that as the jaws move to closed position and as pressure is applied to the nail head, the jaws have a tendency to lift the nail head even before the pointed end of the tool is lifted.

Also, by reference to Figs. 1 and 3, the opening formed by the notches extends through the apex of the pyramidal recess described in the foregoing, the openingbeing thus spaced a slight distance rearwardly of the tool point H and forwardly of the recess proper. Hence the notches, while disposed close to the tool point, are nevertheless bounded by and extend through a substantial depth of thickness of metal (from which the jaws are formed as is conventional) whereby breakage of the tool adjacent its point as might otherwise occur is positively precluded, while at the same time the practical advantages of a nail receiving opening positioned adjacent the tool point and forwardly of the tool cutting edges are obtained, and an exceedingly compact jaw structure results.

In operation, as will be seen from the drawing and the foregoing description, the tapered jaws and sharply pitched and. inclined cutting edges surfaces of various confonnation and further provides increased leverage in pulling nails engaged within the aperture formed by the notches near the point of the jaws. It is of course understood that the jaws are actuated by the handles of the tool and in order to clip nails engaged by the cutting edges the handles are actuated toward each other. In order to pull a nail or tack engaged within the aperture formed by the notches in the jaws, the handles while being firmly urged toward each other are moved downwardly or toward the surface of the object within which the nail is embedded. The inclination of the jaws permits of increased leverage whereby the puller element carrying the nail is lifted with a minimum of pressure upon the handles. The inclination of the jaws further permits the engagement of the nail at a point much nearer the surface inwhich it is embedded than would otherwise be the case. To release the nail from either the clipper or puller element the handles are moved apart or away from each other.

While I have herein described a preferred embodiment of my invention, it is to be understood that the same may be altered in details and arrangement of parts within the scope of the appended claim.

I claim:

A cutting tool of the character described comprising a pair of pivoted jaw members adapted to engage along a meeting line formed by the inner edges of said members, the relatively outer sides of the members being inclined inwardly to provide a tool point, said inner edges being inclined from the horizontal whereby said meeting line is pitched to intersect the plane of the top surfaces of said members substantially at the tool point, said inner edges providing oppositely disposed cutting edges, and the inner sides of said members being each inclined outwardly of the cutting edges and rearwardly of the tool point to provide, when the jaws are closed, a pyramidalshaped recess, one corner edge of which is formed by said meeting line and the apex of which is spaced a small distance rearwardly of said tool point, the inner edges of the jaw members forwardly of said recess being provided with complemental notches extending downwardly through the cutting edges and adapted when in registry to form an inwardly tapered nailor peg-shank receiving opening, said opening being generally vertically arranged and intersecting the apex of the pyramidal-shaped recess thus to extend through a portion of the jaws intermediate the tool point and recess proper.
