SOLE-CUTTING MACHINE.

T '0 all whom it may concern:

Be it known that I,PH1L1PP FUNGK, a citizen of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented certain Improvements in Sole-Cutting Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several The present invention relates to machines for cut-ting soles and is intended primarily for use in operating upon soles for turn shoes although the machine illustrated is capable of performing other work.

In some turn shoes, especially in small sizes, no separate heel is attached to the shoe, but the face of the sole constitutes the tread surface of the shoe not only at the forepart but also at the rear part. It is the practice in the manufacture of such shoes to prepare the sole for the sewing of the upper thereto by cutting an inclined slit or channel along that surface of the sole which is to be uppermost in the finished shoe at a distance from its edge and also by cutting out material at the upper portion of the edge of the sole to form a rabbet or shoulder into which the upper is drawn as it is being sewn to the shoe. Frequently it is preferred to form this shoulder around the forepart and shank of the sole but not around the heel. When this shoulder is cut or formed upon the usual channeling machine, however, it is not possible to produce a square shoulder at the ends of the cut transverse to the line of out and therefore the cut commonly tapers outwardly at its ends to the edge of the sole with the result that the ends of the cut at opposite edges of the sole do not usually correspond wit-h each other, being at different distances from the heel end of the sole. By cutting out, before the channeling operation, a small piece of material, preferably approximately pyramidal in shape, from' opposite edges of the sole, the pieces being cut out from the ,upper side of the sole and being located with their bases at about the distance from the rear end of the sole at which the breast of the heel would come, if a heel were used,

a heel effect may be given'to the shoe Specification of Letters Patent.

since the edge of the sole will be considerably thicker in the rear of the base of the out than forward of it. The preliminary cuts thus made will serve, moreover, as guides for the operator of the channeling machine so that the shoulder knife may be caused to commence and to cease cutting at the proper points. Before the upper has been sewed to the sole, or preferably after such sewing and after the shoe has been turned, the edge of the sole may be forced upward just forward of the base of these cuts so that the shoe will appearto be provided with a low heel.

A principal object of the present invention is to produce a machine which can be operated to cut out pieces of material, preferably approximately pyramidal in shape, rapidly and accurately from opposite edges of a sole. In order to make a clean cut it is considered desirable toprovide cutters each of which has cutting edges acting along the entire surfaces which separate the piece to be cut out from the remainder of the sole.

Accordingly, the present invention comprises a machine provided with means for supporting a sole and cutting mechanism which is constructed and arranged when suitably actuated to cut out pieces of material from opposite edges of the sole. Preferably the cutting mechanism includes a pair of cutters each having angularly disposed cutting edges, one of which acts transversely of the sole to form the base of a pyramidal piece cut out while the other edge is located approximately at right angles to the first edge and separates the side of the pyramidal piece from the remainder of the sole. In the particular embodiment of the invention illustrated, means is provided for separating said cutters from each other while they aremoving through the sole so that the cutters move obliquely with reference to the sole and, if the machine is -properly adjusted, they may be caused first to engage the sole at some distance inside of its opposite edges and then, as the cutting proceeds, to travel outwardly so that the line of out passes through the edge of the sole before the cutters reach the vsurface opposite to that which they first enter ed. I

The invention comprises also novel means by which the cutters may be supported and adjusted so as not only to be capable of moving as above described but also so as to be adjust-able for soles of different widths. 1 ccording to this feature ofthe invention the cutters may be carried by separatesupports or blocks which in turn are mounted to move toward and from each other upon a reciprocable carrier, through which the cutters are moved toward and from the sole, and means is provided for adjusting said cutter supports simultaneously, this adjusting means being so constructed that it does not interfere with the automatic separation of the cutters as they pass into the sole. In the form of construction shown, the cutter supports are threaded to receive co-axial members provided respectively with right and left screw threads and means is provided whereby the said members may be rotated together to adjust the cutters toward or from each other but the members are so supported that they can be moved independently in an axial direction to produce the oblique movement above described.

In addition to the features already specifically referred to the invention comprises also certain other combinations, arrangements of parts and details of construction hereinafter described and claimed.

Referring to the accompanying drawings,-Figure 1 is a view in front elevation of a machine embodying the invention in its preferred form, and Fig. 2 is a View in perspective and partly in central vertical section of a machine shown in Fig. 1 with a sole illustrating the work done shown in place in the machine.

As illustrated, 2 represents a suitable base or supporting plate which may be conveniently secured to a bench or to any other suitable support. A bridge piece a screwed to plate 2 provides a slot or recess through which the sole may be inserted. lVhile this piece 4 is not necessary it may be useful in accurately locating the sole which, however, is positioned upon the base plate 2 principally by an approximately V-shaped gage 6 which is adjustablelongitudinally in a groove 8 in the base plate and which may be clamped in adjusted position by a thumb screw 10. Secured to the base plate 2 by bolts, such as 11, is an upright 12??"recessed.

upon its front side and provided with guide plates 14 overlapping the recess to: provide a guideway for a reciprocating head or slide 16 which serves as a carrier for the cutters and their adjusting devices. The slide 16 is provided upon its forward side with ribs 18 between which is a guideway in the forward part of which the cutter supports 20 are dove-tailed to provide for trans verse movement. The cutters 22, rigidly but removably secured to supports 20, eachcomprise a vertical blade having a cutting edge 24 at its lower end and an inclined blade 26 with cutting edge 28. As shown in the drawings, the two blades are substantially at right angles to each other but the blade 26 is somewhat curved, being shaped approximately as part of a cylinder.

The devices through which the cutters 22 with their supports 20 may be moved and adjusted with reference to each other include a shaft 30 provided with a head 32 and near the head with a threaded member 84 which may be'integral with shaft 30 and which is threaded into the support 20 shown at the right in the drawings. At the left end of shaft 30 is a threaded sleeve 36 splined to shaft 30 so as to rotate with it but so as to be capable of axial movement relatively thereto. The two threaded members 3 1 and 36 are provided with oppositely disposed threads. As shown, the threads upon member 34 areleft-handed and those upon member 36 right-handed. The adjacent inner ends of these thread members are provided with grooved collars 38 which are engaged respectively by forks 10 projecting forwardly from sliding blocks 42 movable horizontally in the rear portion of the guideway formed by the ribs 18 of carrier 16. A spring 46 connecting blocks 20 tends constantly to maintain collars 38 in their innermost positions with the blocks 42 in engagement with a centering pin 44 projecting downwardly between them from the upper rib 18. A wedge block 48 secured to plate 12 projects forwardly so that the upper edge of the wedge is located in a vertical plane passing between blocks 42. In the downward movement of the cutters with the carrier 16 the wedge will act to separate blocks 42 and therefore cutters 22 will be moved in an inclined direction.

Any suitable'means may be provided for reciprocating carrier 16. As shown, a lever 50 pivoted at 52 in ears extending backwardly from upright 12 and actuated, for example, by a spring and treadle (not shown) is provided at its forward end with an enlarged-head 54: engaging the walls of a recess 56 in carrier 16. The downward movement of carrier 16 may be limited by an adjustable screw 58 mounted at the upper end of the carrier and located in position to engage a rearwardly extending lug 60 upon the upright 12.

The operation of the machine illustrated will be obvious from the foregoing description. It may be stated, however, that the sole S will be laid upon the support 2 with its flesh side up and with its heel end resting against the gage 6 which has been adjusted so that the cuts to be made in the sole will be at the desired distance from its heel end. The cross head 16 is then depressed to carry the cutters 22 intothe sole. At about heel effect it will be obvious that either.

with or without slight changes in construction it can readily be adapted for other work. As already noted, this machine is intended for use in cutting a sole prior to the channeling operation and therefore the cuts may be utilized by the operator in channeling the sole as guides to indicate where the channeling should begin and end whether or not a heel effect is desired. Therefore the invention is not limited to the specific structure or use described and illustrated but covers modifications which will occur to one skilled in the art and which are within the scope and spirit of the invention as defined in the claims.
