INVENTOR ANTONIQ FACCIUTO fir ATTORNEY Patented Dec. 16, 1952 SHOEMAKERS CHISEL FOR CUTTING V-SHAPED NOTCHES.

Antonio Facciuto, Alhambra, Calif.

Application June 13, 1949, Serial No. 98,665

3 Claims.

The present invention relates to chisels in general and more particularly to a shoemakers chisel used in seating metallic inserts in shoe heels and the like. More specifically the invention comprises a single unitary chisel formed with a V-shaped cutting edge and an integral force-receiving shank adapted to cut V-shaped notches from shoe heels to enable the shoemaker to position therein metallic inserts having greater wearing qualities than the removed leather.

shoemakers have long made use of metallic inserts in the heels of shoes to increase their wearing qualities and to prevent running over. In positioning such inserts the shoemaker usually takes a pattern or templet sized to correspond to the metallic insert, places it at the edge of the heel where the insert is to be positioned, makes suitable marks around the templet, removes the templet, and then cuts the heel along the marks as by means of a knife edge driven by a mallet. The cut-out portion of the heel may be one or two layers of leather deep and is sized to receive the insert which usually is provided with a flat flange at its lower surface to extend under the layer of leather at the sides of the cutout portion.

This method is well known and has the objection that it is time consuming and not too accurate. The sides of the recess are cut separately and the included angle does not always conform exactly to the insert. Sometimes the cut-out section is too large and at other times not sufficiently large.

One variant of the usual method comprises the shoemaker placing the insert in an inverted position upon the bottom of the heel overlying its final position and then striking it a blow with his mallet. The leather is slightly indented and the shoemaker can use those markings so obtained in place of the markings obtained with the templet, as previously described.

According to the present invention there is no necessity to use marking means or templets. The chisel comprising the invention is shaped to conform to the shape of the metallic insert to be positioned in the heel. By properly positioning the cutting end of the chisel upon the heel and then striking it with a hammer or a mallet the desired layer or layers of the heel are cut or notched to conform precisely to the shape of the metallic insert. Both sides of the notch are cut simultaneously, the cut-out conforms exactly to the insert, and inaccuracies are entirely eliminated.

With an appreciation of the problems present in the field, it is an object of the present invention to provide a new and improved chisel for shoemakers.

It is another object of the invention to provide a chisel having a V-shaped cuttin edge usable by shoemakers for the seating of wearresisting elements in shoe heels.

These and other more specific objects will appear upon reading the following specification and claims and upon considering in connection therewith the attached drawing to which they relate.

Referring now to the drawing:

Figure 1 is a partial side View of a mans shoe with the heel shown partly in section and a reinforcing metallic insert positioned therein;

Figure 2 is a bottom view of the heel of the shoe of Figure 1 and shows one insert positioned and a second cut-out ready to receive an insert;

Figure 3 illustrates a chisel constructed in accordance with the present invention positioned as in cutting the insert notch in a shoe heel, the chisel being shown partly in section;

Figure 4 is a side view of the chisel per se looking in the direction of the arrows upon the line 4-4 of Figure 3;

Figure 5 is an end view of the chisel looking in the direction of the arrows upon the line 55 of Figure 4; and

Figure 6 is a View in perspective of the chisel.

In the drawing a common shoe for men is indicated generally by the reference character II and is seen to comprise a heel, indicated generally at l2, having a bottom layer it of leather or the like. Experience has shown that in use the heel wears faster around its rear curvature and that its life is prolonged by positioning of metallic inserts in the fastest wearing areas. Such an insert is illustrated in Figures 1 and 2 and is seen to comprise a V-shaped main body portion It, from one face of which extends laterally a relatively thin integral flange ll adapted to be wedged under the layer It and at the sides of body it. Body It is centrally bored at 18 and seats a nail is which extends into the heel and retains the insert in place.

The body It of the insert is positioned within and abuts the sides of a V-shaped cut-out or notch 2i and it is in the tool for making this cut-out that the present invention resides.

Referring now particularly to Figures 3, 4, 5 and 6 the tool comprising the present invention is illustrated and is seen to comprise a metallic chisel, indicated generally by the reference character 25, formed of an elongated rectangular body or shank 26, the corners of which are preferably beveled, the chisel being flat at end 21 and transversely V-sectioned at its opposite end formed by the cutting edges 29. The latter are located at the ends of two side walls 3!, each of which is vertically V-sectioned in the sense of tapering toward the cutting edge at its extremity; the walls 3| form between themselves a channel and converge, as illustrated at 32, and merge into the shank 26. The outer faces of side walls are preferably approximately perpendicular with respect to the plane of the cutting edges 29, as is illustrated in Figure 4, so that the cut-out will have substantially vertical side walls. As is clearly seen in Figures 3, 4 and 5 the side walls form between them a forwardly opening recess or channel which is pie-shaped in each vertical wall as in each horizontal section.

In use the shoemaker places the chisel 25 with the outer extremities of the V-shaped cutting edges 29 in alignment with the edge of the heel and then delivers a sharp blow or blows to the flat end 21 of the body 26. The chisel is driven inwardly to the position illustrated in Figure 3, cutting layer 13, the cut-out material of the heel being forced outwardly by the converging V-shaped inner curvature of the walls 31. The shoemaker then removes the chisel, places the insert 16 in the cut-out 2| with its flange Il underlying the layer I3, and secures it in place by the nail 19. The layer l3 may then be nailed more firmly in place if desired.

While the particular apparatus herein shown and described in detail is fully capable of attaining the objects and providing the advantages hereinbefore stated, it is to be understood that it is merely illustrative of the presently preferred embodiments of the invention and that no limitations are intended to the details of construction of design herein shown other than as defined in the appended claims,

I claim:

1. A shoemakers hand-held chisel comprising an elongated metallic body formed at one end with angularly arranged cutting edges and for the major portion of its length as a shank adapted to transmit a driving force in the direction of its major axis tosaid edges, characterized in that said end comprises angularly disposed side walls forming therebetween a channel, the ends of said walls having sharpened cutting edges, said channel being V-shaped and tapering in width from the cutting edges to its upper end.

2. The construction recited in claim 1 characterized in that said side walls of said channel are V-sectioned parallel to said axis of said shank, their exterior surfaces extending parallel to said axis.

3. The construction recited in claim 1 characterized in that said side walls of said channel are V-sectioned parallel to said axis, their interior surfaces converging and meeting at the upper end of the channel.
