STITCH-REMOVING PUNCH.

Specification of Letters Patent.

Application filed June 1, 1908.

Patented Mar. 15, 1910.

Serial No. 435,938.

To all whom it may concern:

Be it known that I, O'r'rnn JOHNSON, a citizen of the United States, residing in the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in Stitch-Removing Punches; and I do 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, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in devices for removing the threads or stitches from the welt of a shoe, before applying a new sole thereto. It is found in practice that it is necessary to remove these stitches in order that the applying of the new sole may be neatly done.

The object of my improved device is to greatly facilitate the work of removing the two stitches from the openings formed by the sewing awl.

My improved device consists of a pair of jaws connected to cooperate with each other. One of these jaws is recessed at one extremity and the projecting parts on opposite sides of the recess are adapted to enga e the layer from which the stitches are to be punched. The other aw is provided with a punching pin or projection adapted to enter the awl holes and remove the stitches from the welt.

Having briefly outlined my improved construction, I will proceed to describe the same in detail reference being made to the accompanying drawing in which is illustrated an embodiment thereof.

I11 this drawing, Figure 1 is a perspective view of my improved stitchremoving punch. Fig. 2 is a fragmentary side elevation of the same shown on a larger scale. In this view a shoe is shown in section, the punch being shown in position for removing the stitches from the welt. Fig. 3 is a fragmentary detail view of one of the jaws. In this specification this will be termed the lower jaw. This is a View looking in the direction of arrow 3 Fig. 2. Fig. 4 is a similar view of the upper jaw looking in the direction of arrow 4.

The same reference characters indicate the same parts in all the views.

Let the numerals 5* and 6 respectively designate the upper and lower jaws of my improved tool. These jaws are crossed at their rear extremities and pivotally connected together as shown at 7. Their handle members 8 and 9 extend rearwardly whereb the necessary leverage is obtained for per orming the stitchremoving function. The lower jaw 6 is provided at. its forward extremity with a recess 27 having projections 28 on opposite sides thereof, said projections being turned inwardly as shown at 29.

The upper jaw or that designated 5, is provided with a depending stud or pro ection 10 having a reduced free extremity 12 adapted to perform the stitch removing function. The extremity 12 is of sufficient length to pass entirely through the welt 13 of the sole, whereby the stitches 1-1 are removed. The punch point 12 is arranged to register with the recess 27 of the lower jaw. This recess makes room for the ejected stitches, while the members 28 extend underneath the protruding part or welt 13, thus forming a support for the welt during the stitch-removing operation.

As shown in the drawing, a coil spring 15 is interposed between the two jaws 5 and 6. Each of these jaws is preferably recessed as shown at 17, to receive the opposite extremities of the spring. A short stud or pin 18, protrudes inwardly from each jaw to aid in holding the spring in place. This spring normally holds the two jaws in the open position.

From the foregoing description the use of my improved stitch punch will be readily understood. Assuming that the outer portion of the sole has been removed, leaving the welt 13 only, the lower jaw 6 of my improved device is placed under the protruding edge of the welt after which the upper jaw o is forced downwardly causing the reduced pin extremity 12, to engage the stitch 14. and remove it from the awl hole. It may be readily moved along the edge of the welt 13, until all the stitches have been punched out. Usually these stitches or their parts, will adhere to the sole but may be readily scraped off.

Having thus described. my invention, what I claim is:

A stitch removing punch, provided with two cooperating jaws pivotally connected together, one of said jaws being provided with a recess having inwardl turned projections upon the opposite si es thereof locnted adjacent its free extremity, the opposite jaw having a stud arranged at right angles and provided with a reduced punch point arranged to register with the inner portion of the recess in the opposite jaw for stitch removing purposes, the extremities of the recessed jaw extending considerably beyond the punch point to give the tool a firm hold on the Welt, substantially as described. 10

In testimony whereof I nfliX my signature in presence of two Witnesses.
