Definitions
- This invention relates to machines for performing that particular operation on the edge of the sole of a boot or shoe known as cutting in and is of that class of cutting in machines which is shown and described in U. S. patent to C. S. Gooding and S. E. Taft No. 939,007, dated November 2, 1909, and in which a rotary cutter is employed cutting transversely of the edge of the shoe adjacent to the breast of the heel.
- the invention has among its objects to improve the gages and guards which .are used in connection with said rotary cutter, to facilitate the speed with which the posi tioning of the shoe may be accomplished and also to increase the speed with which the cutting in operation can be performed, and furthermore the invention has for its object to make a convex edge upon the sole of the shoe adjacent to the breast of the heel during the cutting in operation, so that the portion adjacent to the breast of the heel shall be substantially a copy in cross sectional contour of that part of the edge of the shank portion of the sole of the shoe which has already been trimmed by the ordinary shank cutter.
- the invention still further has for its object to perform the cutting in operation by one downward movement of the shoe relatively to the periphery of the cutter.
- the invention relates particularly to the gage which rests against the upper face of the sole of the shoe during the trimming operation and to the gage at the front of the cutter which rests against the edge of the sole of the shoe.
- the gage which enters the crease of the shoe between the upper and the upper face of the sole and rests preferably against the upper face of the sole is movable relatively to the rotary cutter and preferably is rotatably mounted to move about the median axial line of the rotary cutter.
- This gage on account of the small amount of space which can be utilized therefor is preferably supported upon a guard which extends across the periphery of the rotary cutter and protects the upper of the shoe from injury.
- the gage at the front side of the cutter rests against the edge of the sole which has already been trimmed by the rotary shank cutter of the ordinary edge trimming machine, and, as will be hereinafter fully described, the edge of the shank portion of the shoe which has been trimmed rests against this front edge gage and forms a pattern which coacts with said front edge gage in such a. manner that the rotary cutter, in its cutting in operation, reproduces the sectional contour of said trimmed edge on the edge of the sole trimmed thereby adjacent to the breast of the heel.
- the front edge gage is preferably mounted loosely upon a stud upon the front end of the shaft to which the rotary cutter is fastened and concentric therewith, so that it will rotate as the shoe is carried downwardly, as hereinbefore set forth, by means of the frictional contact of the edge of the shank portion of the sole of the shoe with the periphery thereof, but this front gage may be made stationary, if .desired, without departing from the spirit of my invention.

- a rotary cutter 13 is fastened to the main driving shaft 11 and is preferably clamped thereto by a screw 14 and collar 15.
- a breast gage 16 is preferably fastened to the shaft by being clamped between the cutter 13 and a shoulder 17 formed on said shaft.
- An edge gage 18 is preferably rotatably mounted upon the collar 15, this edge gage being adapted to rest against the edge of the shank portion of the sole.
- the breast gage 16 is adapted to rest against the breast of the heel of the shoe which is being trimmed.
- a guard 19 extends across the periphery of the cutter 13 and is fastened to a carrier 20 rotatably mounted upon the shaft 11.
- the guard 19 is preferably made in two parts 21 and 22 which extend across the periphery of the cutter and have a space 23, forming a slot or opening, between their adjacent edges 24 and 25, respectively.
- the part 21 is fastened directly to the carrier 20 (Fig. 4) and the part 22 is fastened to the part 21 by means of screws 26, 26 which project through slots 27, 27 in the part 22 and have screwthreaded engagement with the part 21, so that said part 22 can be adjusted circumferentially 0f the cutter and the edge 25 brought nearer to or farther away from the edge 24, thus narrowing the space 23 between the adjacent edges 24 and 25, as may be desired.
- the carrier 20 is shown as rotatably mounted upon the shaft 11, but it is evident that the same may be mounted upon a stationary support, if desired, as, for instance, the bearing sleeve 28 may be extended to form a support for said carrier.
- the carrier 20 has a segmental flange 29 thereon which projects into an annular groove 30 formed in a screw 31 which has screw-threaded engagement with the frame 10 of the machine, so that by turning said screw 31 in one direction or the other, the carrier 20, and consequently the guard 19, can be adjusted longitudinally of the shaft 11 and relatively to the periphery of the cutter so as to make more or less space between the inside of the parts 21 and 22 of the guard 19 and the periphery of the cutter 20, when desired.

- a gage 38 projects outwardly and preferably upwardly from the edge 24 of the part 21, this gage being adapted to rest against the upper face of the sole 39 of the shoe adjacent to the edge thereof and adjacent to the breast of the heel and projecting outwardly from the part 21.
- a stop 40 is adjustably secured by screws 41 to the part 22 of the guard and overhangs the slot 23 projecting away from the periphery of the cutter as best shown in Figs. 2, 3 and 6.
- the end of the stop 40 is so positioned that it will engage the tread face of the sole at a substantial distance from its edge and limit the tipping or locking movement of the shoe during the trimming oper ation.
- the general operation of the machine hereinbefore specifically described is as follows:
- the shoe is held by the operator as illustrated in Figs. 4, 5 and 6 with the upper face of the sole of the shoe adjacent to the breast of the heel resting on the gage 38, with the gage 18 resting against the edge of the sole and with the gage 16 resting against the breast of the heel.
- the operator then moves the shoe downwardly from approximately the position illustrated in Fig. 8 in full lines to that shown in dotted lines.
- the rotary cutter 13 trims the edge of the sole 39 from the breast portion of the heel up to that portion of the edge of the sole which has been previously trimmed and imparts to it a convex rounded edge of substantially the form of that portion of the edge of the sole against which the gage 18 rests, said gage 18 thus acting, in conjunction with the edge of the sole which has been previously trimmed, as a pattern to guide the shoe relatively to the cutter during the downward movement of the shoe so as to trim the edge of the sole which has not been trimmed and give the same a convex curve in cross section.
- gage 16 during the trimming operation rests against the breast of the heel of the shoe and the upper face of the sole .rests against the gage 38 and rocks slightly thereon as the shoe is pushed downwardly by the operator.
- the carrier 20 tips or rocks upon the shaft 11 and is assisted by the hand of the operator in this rocking motion, if desired, by means of the handle 32, it being understood that during the trimming operation the two parts 21 and 22 of the guard 19 tip or rock with said carrier 20 and always prevent the upper of the shoe from coming into contact at any point of the trimming operation with the rotary cutter 13.

SYDNEY E. TAFT, OF SOUTH FRAMING-HAM, MASSACHUSETTS, ASSIGNOR, BY MESNE ASSIGNMENTS, TO UNITED SHOE MACHINERY COMPANY, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY.
MACHINE FOR CUTTING IN THE SHANKS OF SHOES.
Specification of Letters Patent.
Patented Dec. 24,1912.
To all whom 'it may concern:
Be it known that I, SYDNEY E. TAFT, a citizen of the United States, residing at South F ramingham, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements 1n Machines for Cutting in the Shanks of Shoes, of which the following is a specification.
This invention relates to machines for performing that particular operation on the edge of the sole of a boot or shoe known as cutting in and is of that class of cutting in machines which is shown and described in U. S. patent to C. S. Gooding and S. E. Taft No. 939,007, dated November 2, 1909, and in which a rotary cutter is employed cutting transversely of the edge of the shoe adjacent to the breast of the heel.
The invention has among its objects to improve the gages and guards which .are used in connection with said rotary cutter, to facilitate the speed with which the posi tioning of the shoe may be accomplished and also to increase the speed with which the cutting in operation can be performed, and furthermore the invention has for its object to make a convex edge upon the sole of the shoe adjacent to the breast of the heel during the cutting in operation, so that the portion adjacent to the breast of the heel shall be substantially a copy in cross sectional contour of that part of the edge of the shank portion of the sole of the shoe which has already been trimmed by the ordinary shank cutter.
The invention still further has for its object to perform the cutting in operation by one downward movement of the shoe relatively to the periphery of the cutter.
The invention relates particularly to the gage which rests against the upper face of the sole of the shoe during the trimming operation and to the gage at the front of the cutter which rests against the edge of the sole of the shoe. The gage which enters the crease of the shoe between the upper and the upper face of the sole and rests preferably against the upper face of the sole is movable relatively to the rotary cutter and preferably is rotatably mounted to move about the median axial line of the rotary cutter. This gage, on account of the small amount of space which can be utilized therefor is preferably supported upon a guard which extends across the periphery of the rotary cutter and protects the upper of the shoe from injury. The gage at the front side of the cutter rests against the edge of the sole which has already been trimmed by the rotary shank cutter of the ordinary edge trimming machine, and, as will be hereinafter fully described, the edge of the shank portion of the shoe which has been trimmed rests against this front edge gage and forms a pattern which coacts with said front edge gage in such a. manner that the rotary cutter, in its cutting in operation, reproduces the sectional contour of said trimmed edge on the edge of the sole trimmed thereby adjacent to the breast of the heel.
In the cutting in operation, the operator, therefore, places the upper face of the sole against the crease gage and moves the shoe downwardly once and then removes the shoe from the machine, the work thus being performed in a single operation. The front edge gage is preferably mounted loosely upon a stud upon the front end of the shaft to which the rotary cutter is fastened and concentric therewith, so that it will rotate as the shoe is carried downwardly, as hereinbefore set forth, by means of the frictional contact of the edge of the shank portion of the sole of the shoe with the periphery thereof, but this front gage may be made stationary, if .desired, without departing from the spirit of my invention.
Other features of the invention including certain combinations and arrangements of parts will be set forth in the following description and particularly pointed out in the claims.
Referring to the drawings: Figure 1 is a side elevation of my improved machine for cutting in the shanks of shoes, a portion of the same being broken away to save space in the drawings. Fig. 2 is a front elevation of the same with the parts in position to begin the cutting in operation. Fig. 3 is a front elevation of the same with the parts in the relative positions assumed thereby when the cutting in operation is just being completed. Fig. 4 is a plan view of the rotary cutter, its carrying shaft and the front bearing, together with the gages and guards, the cutter, gages and guards being shown in section and a portion of a shoe shown in connection with said cutter in dotted lines. Fig. 5 is a sectional elevation taken on line 5-5 of Fig. 4 looking toward the left in said figure and a portion of a shoe being shown in proper posit-ion to be trimmed in connection therewith. Fig. 6' is a perspective view taken from the front of the machine and illustrating the rotary cutter and the different gages and guards, with a portion of a shoe shown in proper position to be trimmed in connection therewith.
Fig. 7 is a perspective view of the carrier for the edge gage and upper guard as viewed from the rear of the machine looking toward the front. Fig. 8 is a detail diagrammatic view illustrating the shoe sole and cutter and the manner in which the sole is moved from one position to another to obtain the convexly curved edge in the trimming operation.
Like numerals refer to like parts throughout the several views of the drawings.
In the drawings, 10 is the frame of the machine and 11 the main driving shaft adapted to rotate in suitable bearings, one of which 12 is shown in the drawings. A rotary cutter 13 is fastened to the main driving shaft 11 and is preferably clamped thereto by a screw 14 and collar 15.
A breast gage 16 is preferably fastened to the shaft by being clamped between the cutter 13 and a shoulder 17 formed on said shaft. An edge gage 18 is preferably rotatably mounted upon the collar 15, this edge gage being adapted to rest against the edge of the shank portion of the sole. The breast gage 16 is adapted to rest against the breast of the heel of the shoe which is being trimmed.
A guard 19 extends across the periphery of the cutter 13 and is fastened to a carrier 20 rotatably mounted upon the shaft 11. The guard 19 is preferably made in two parts 21 and 22 which extend across the periphery of the cutter and have a space 23, forming a slot or opening, between their adjacent edges 24 and 25, respectively. The part 21 is fastened directly to the carrier 20 (Fig. 4) and the part 22 is fastened to the part 21 by means of screws 26, 26 which project through slots 27, 27 in the part 22 and have screwthreaded engagement with the part 21, so that said part 22 can be adjusted circumferentially 0f the cutter and the edge 25 brought nearer to or farther away from the edge 24, thus narrowing the space 23 between the adjacent edges 24 and 25, as may be desired.
The carrier 20 is shown as rotatably mounted upon the shaft 11, but it is evident that the same may be mounted upon a stationary support, if desired, as, for instance, the bearing sleeve 28 may be extended to form a support for said carrier. The carrier 20 has a segmental flange 29 thereon which projects into an annular groove 30 formed in a screw 31 which has screw-threaded engagement with the frame 10 of the machine, so that by turning said screw 31 in one direction or the other, the carrier 20, and consequently the guard 19, can be adjusted longitudinally of the shaft 11 and relatively to the periphery of the cutter so as to make more or less space between the inside of the parts 21 and 22 of the guard 19 and the periphery of the cutter 20, when desired. The carrier 20 has a handle 32 fast thereto and of suitable shape to be conveniently operated by the operator during the cutting operation to rock said carrier upon the shaft 11. i
A spring 33 is connected at one end to a pin 34 fast to an ear 35 on said carrier and at the other end said spring is connected to a rod 36 fast to the frame of the machine. The carrier 20 also has a stop lug 37 thereon which is adapted to strike against the screw 31 and limit the distance to which the carrier can be rocked by the spring 33 in one direction.
A gage 38 projects outwardly and preferably upwardly from the edge 24 of the part 21, this gage being adapted to rest against the upper face of the sole 39 of the shoe adjacent to the edge thereof and adjacent to the breast of the heel and projecting outwardly from the part 21.
A stop 40 is adjustably secured by screws 41 to the part 22 of the guard and overhangs the slot 23 projecting away from the periphery of the cutter as best shown in Figs. 2, 3 and 6. The end of the stop 40 is so positioned that it will engage the tread face of the sole at a substantial distance from its edge and limit the tipping or locking movement of the shoe during the trimming oper ation.
The general operation of the machine hereinbefore specifically described is as follows: The shoe is held by the operator as illustrated in Figs. 4, 5 and 6 with the upper face of the sole of the shoe adjacent to the breast of the heel resting on the gage 38, with the gage 18 resting against the edge of the sole and with the gage 16 resting against the breast of the heel. The operator then moves the shoe downwardly from approximately the position illustrated in Fig. 8 in full lines to that shown in dotted lines. During this downward movement, the rotary cutter 13 trims the edge of the sole 39 from the breast portion of the heel up to that portion of the edge of the sole which has been previously trimmed and imparts to it a convex rounded edge of substantially the form of that portion of the edge of the sole against which the gage 18 rests, said gage 18 thus acting, in conjunction with the edge of the sole which has been previously trimmed, as a pattern to guide the shoe relatively to the cutter during the downward movement of the shoe so as to trim the edge of the sole which has not been trimmed and give the same a convex curve in cross section. gage 16 during the trimming operation rests against the breast of the heel of the shoe and the upper face of the sole .rests against the gage 38 and rocks slightly thereon as the shoe is pushed downwardly by the operator. During this pushing down of the shoe and the trimming of the edge thereof, the carrier 20 tips or rocks upon the shaft 11 and is assisted by the hand of the operator in this rocking motion, if desired, by means of the handle 32, it being understood that during the trimming operation the two parts 21 and 22 of the guard 19 tip or rock with said carrier 20 and always prevent the upper of the shoe from coming into contact at any point of the trimming operation with the rotary cutter 13.
