LEATHER CUTTING TOOL Filed Oct. 30, 1945 Patented Aug. 15, 1950 "UNITED STATES PATENT OFFICE" LEATHER-QU'TTINGTOOL I Walter Kolodnicki, New London, (lo nn. Application October so, 1945, Serial No. 625,486

I 1 This'invention relates to a tool for cutting leather into narrow strips or lace.

An object of this invention is to provide an improved leather-cutting tool which may be adjusted to cut different widths of strips from a piece of leather and which may also be adjusted toaccommodate different thicknesses of leather. A further object of this invention is to provide an improved'tool for cutting leather into narrow strips or thongs in which the blade is adjustable to cut varying widths of strips and in which a gauge block is adjustable to admit leather of varying thicknesses.

Still another object of this invention is to provide an improved lace-cutting tool for leather which is so construced as to cut a length of lace spirally from the center of an odd-shaped piece of leather. 7

Other objects of this invention will appear from" the following specification and claim and from the. accompanying drawings illustrating the invention, wherein:

Figure 1 is a front elevational view of the cutting tool with the parts assembled in operative position;

Figure 2 is a side elevational view of the cutting tool assembled for operation;

Figure 3 is a rear elevational view with the gauge block partially cut away and partially disassembled to show the construction;

Figure 4 is a sectional view taken on line 4-4 of Figure 1 and showing the knife construction;

Figure 5 is a detail view of the knife blade holder; and

Figure 6 is a fragmentary piece of leather showing the manner in which a lace is cut spirally from the middle portion thereof.

Referring to the figures, I is the handle and 2 is the body of the cutting tool. The body has 7 a narrow upstanding lug 3 having a slot 4 therein.

A gauge block 5 is carried by a threaded screw *5 extending through slot 4 and having a knurled thumb-piece I on its end. Rotation of the screw 6 while gauge block 5 is held from rotation will cause the gauge block to approach lug 3 until it abuts said lug, as shown in Figure 1. The slot 4 permits the distance between the block 5 and the body 2 to be varied, and tightening of the thumb-piece 1 will hold the gauge block 5 in any adjusted position relative to the body 2.

The body 2 is provided with a horizontally extending slot 8. Extending through slot '8 is a threaded knife blade holder 9 having a slot I0 therein for receiving a knife blade I I. A knurled .nut I2 is provided for holding the blade II, in-

' 1 Claim. (01. 30-293) serted in slot I0, against the body 2 and the gauge block 5., As can be seen from Figure 4, the blade is inserted in slot [0 so that the knife edge bears against the body 2 and the block 5. .The slot 8 permitsthe blade to be adjusted horizontally to vary the distance between the blade I I and the lug 3. The nut I2 will hold the knife in any adjusted position. The gauge block 5 has its' face scored to indicate units of distance from the lug 3.

In operation, assuming'the parts are in the position shown in Figure 1, if the notch I3 formed between the gauge block 5 and the body 2 does not conform to the thickness'of the leather to be out, it is necessary to first loosen block 5 slightly by turning the screw 6. This will enable block 5 "to be pushed up or down to provide for notch I3 being of the right size to admit the thickness of the leather. Screw 6 is tightened in the adjusted position. It is then necessary to adjust the position of knife blade II so that its distance from the lug 3 conforms with the width of the lace or strip it is desired to cut from the piece of leather. This adjustment is accomplished by loosening the nut I2 slightly, moving the holder 9 and blade II to the proper position, and then tightening the nut I 2.

To cut a strip from the leather piece, it is merely necessary to push the forward end of the piece of leather into notch l3 with onev side of the piece of leather abutting the lug 3. Then while the cutting tool is held in one hand, the other hand is used to draw the piece of leather through the cutting tool while maintaining the piece of leather against the lug 3. A thong or strip whose width conforms to the distance between the blade II and the lug 3 will thus be formed. The operation will be facilitated if a small cut is first made in the forward end of the piece of leather so that the forward end of the piece of leather will protrude through the cutting tool slightly to facilitate gripping.

The cutting tool is so constructed as to enable a thong to be cut out of the center of an oddshaped piece of leather. As seen in Figure 6, a portion I4 about the size of a quarter is first cut out of the center of the leather piece. Then a circular cut I5 is started for about an inch and a half and of the desired width to form the beginning of the thong. Then the piece of leather is inserted in notch I3 with the lug 3 extending through the opening I4, and the end I5 of the thong fitting into the space between the lug 3 and the blade I I. To enable placing the leather in this position, the knife blade II is first loosened and rotated or lowered to clear the notch l3, and after the piece of leather is slipped over the tool, the blade II is returned to its proper position. With the leather in position as indicated above, it is merely necessary to pull on the end l5 of the thong while holding the tool, and the blade I I will cut a thong spirally from the piece of leather while the leather inflat s. Inns, this u ting imdl p rmits the cutting ofgthpngsglfnom odd pieqespo fleather that are normally discarded as scrap.

While a certain specific embodiment of this invention has been shown, it will be understood that various modifications may be made with in the spirit of the invention. limitations on the invention are intended other than are imposed by the scoperofthe appended claim.
