lNSEAM-TRIMMING MACHINE.

SPECIFICATION forming part of Letters Patent No. 788,796, dated May 2, 1905.

Application filed July 16, 1904. Serial No- 216,911-

To all w/wm it may concern:

Be it known that I, JAMES O. SELBY, a citizen of the United States, residing at Portsmouth, in the county of Scioto and State of Ohio, have invented certain new and useful Improvements in Inseam-Trimmin Machines; and I do hereby declare the fol owing 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.

The present invention. relates to inseamtrimming machines, and more particularly to inseam-trimming machines adapted for operation upon welted shoes.

The invention is intended primarily as an improvement on the machine disclosed in the patents to French and Meyer, No. 558,379, dated April 14, 1896, and No. 590,831, dated Se tember 28, 1897, but is also applicable to ot 1 er inseam-trimming machines, and it is to be understood that, except as defined in the claims, the invention is not limited to any particular construction and arrangement of the various parts of an inseam-trimming machine.

The machine disclosed in the patents to French and Meyer above referred to can be used to trim the inseams of welted shoes in a satisfactory manner; but it has been found that considerablecare and skill are required to trim the seams closely and uniformly without occasionally cutting so deep as to injure or spoil the shoe. It has also been found in the use of said machine that the projecting edge of the upper along the sides of the shoe is not always trimmed off by the knife, but is turned over against the welt without being cut. This is especially notice able when the upper is thin and pliable.

The object of the present invention is to provide means particularly applicable to the machine of the French and Meyer patents, but also capable of use in other inseam trimming machines, whereby the inseam of a Welted shoe can be trimmed closely and evenly without liability of injuring or spoiling the shoe and without any special care or skill on the part of the operator.

A further object of the invention is to provide means whereby all portions of the projecting edge of the upper, no matter how thin and pliable, can be trimmed off by the trim ming-knife in a certain and reliable manner.

Other objects of the invention are in general to improve the construction and mode of operation of machines for trimming the illseams of welted shoes.

In accordance with the present invention the above objects are secured by the pro- 6o vision in an inseam-trimming machine of a guide arran 'ed to bear upon the edge of the welt of a we ted shoe at the side of the upper and regulate the depth of the cut made by the knife. As is well known, the welt of a welted shoe is provided upon its under surface with a groove in which the stitches of the inseam are located, and this groove extends the entire length of the welt at a uni form distance from its inner edge. All por- 7o tions of the inner edge of the welt are thus located a uniform distance from the stitches of the inseam, and the provision of a guide bearing upon this edge of the welt insures an accurate and uniform trimming of inseam. The guide bears on. a portion of the inseam, so that a careless tipping of the shoe by the operator will not cause the knife to cut the stitches, while an inward movement sufficient to bring the knife in contact with the stitches is absolutely prevented. Furthermore, the guide is located farther away from the sole than the knife, so that it can extend in the direction of the feed close to or beyond the cutting edge of the knife and bear upon the inseam directly over the point at which the cut is being made. In addition to preventing the trimming-knife from cutting the stitches of the inseam the guide also forms a support for the upper While being cut by the knife and prevents it from being turned over against the welt, so that a thin and pliable upper can be trimmed in as satisfactory a manner as a thick upper. Preferprovided the guide which bearsupon the.

edge of the welt is preferably so mounted that it can be adjusted toward and from the crease-guide in aplane substantially parallel to the plane of the sole, the object of this adjustment being to bring the guide into a positionto beaRagainSt-the edge of the welt at the side of the upperregardless of the distance fromthe-edge of the sole at which the lip. is located;

The present invention-will be clearly understood from an inspection .of the'accom pany-ing, drawings, in which- Figure 1 is a viewinfront elevationof so much of an-inseam-trimming-machine as is necessary to. show the connection of theinvention therewith. Fig. 2 is a: view in end eleva: tion of the machine illustrated in Fig, 1 with certain. parts omitted. Fig. 3. is a detail sectionalview showing ashoe in position tobe actediupon by the instrumentalities ofthe machine and illustrating particularlytherelative arrangement of the guide which bears upon the edge ofthe welt, the sole-guide, and the creascegnider Fig. 4 is-a detail :view, in front elevation, of. the guide which bears against the edge of the welt; and Fig. 5. is abottom-gplan view of the guide. illustratedin Fi 4.

The. machine illustrated inthe drawings, exceptas hereinafterdescribed, is the same in theconstruction, arrangement, and modev of operation of its yariousparts as the machine. disclosed in the atentsto French and Meyer hereinbeforeere erred to, reference to.

which maybe had for a complete disclosure thereof.

Referring to the drawings, 1 indicates the;

ting edge of the knife and extends within thev periphery of the knife and isalso so shaped that it bears upon the solein close proximity.

to the lip.

In applying the present invention to, the machine of the French and Meyer patents a guide 6 has been provided which is arranged to bear upon the edge of the welt at the side of the upper. This guide is located inside of the periphery of the knife and extends be yond the cutting edge, as is clearly shown in Fig. 1. As illustrated, the guide 6 is adjustably secured to the lower end of a block 7 by means of a screw 8, passing through a slot in the base of the guide, the object of this construction being to enable the guide to be adjusted in a plane at right angles to the cutting edge of the knife to vary the depth of the out. The block 7 is provided with a vertical slot 9, through which a securing-screw 10 passes and screws into the block 11,from which the sole-guide 5 is supported. This means for securing the block 7 allows the guide 6 to. be adjusted toward and from the crease-guide in a plane substantially parallel with the surface of the sole, the object of this adjustment beingto bring the guide 6. into a position in whichit will bear upon the edge of the welt at the side of the upperwhen the crease-guide isseated in the bottom of the crease between the upper and welt.

The manner in which the shoe is guided to the trimming-knife will be, clearly understood. from an inspection. of Fig. 3, from which itwill be seen thatthecrease-guide bears against the upper in the crease between the upper and welt. The guide 6 bears upon the edge of the welt atone side of the upper, andthe guide 5 bears against the sole inside of the lipat the other side of the upper; The guide 6 bears on a portion of the inseam, so that it is in a position to ab-v solutely prevent an inward movement of the shoe sufficient to cause the'knife to cut the stitches:unitingtheweltand upper to the sole even if the shoe is carelessly manipulated by the operator. The edges of the upper and lining projectinto the space between the.

guides 5 and-6, so that they are maintained in a position to. be cut. by the knife. The knife rotates in the direction indicated by the arrowin Fig; 3, and any tendency of the knife to turn the edges-of the upper and lining over against the welt without cutting. them'is resisted by theguide 6, the side of which bears: against the upper and holds it up against the action of the knife.

The object andnatureof the. invention having, been indicated and a specific embodiment of the invention ha-vin been illustrated and described, what is claimed is 1. An inseam-trimming machine, having, in combination, atrimming-knife, and means. for guiding a welted shoe comprising a guide arranged to bear upon the edge of the welt at oneside. of the upper and support the upper while beingcut by the knife, substantially asdescribed.
