LAWSON, OF BEVERLY, MASSACHUSETTS, ASSIGNOR TO UNITED SHOE MACHINERY CORPORATION, 0F PATERSON, NEW JERSEY, COR-PORATION OF NEW JERSEY MACHINEFOR USE IN OPERATING UPON THE BOTTOMS OF BOOTS AND SHOES Application filed September 1l, 1930. Serial No. 481,269.

of the United States No. 1,706,504, granted March 26, 1929, on application of George E. Yarren, the ends of a short outsole and attachedxvelt at the rear of the heel breast line are trimmed to form two finished surfaces shaped to fit accurately against corresponding finished surfaces of a heel unit.

An object of the present invention is to provide an improved and substantially auto- `matic machine by which cutting operations such as the outsole and Welt trimming operation just referred to may be performed quickly and effectively. Y

ln the organization of the illustrated machine, a Work support or jack movable into' and out of operative relation to the operating instrumentalities of the machine is provided and the construction 'and arrangement are such that upon initial movement of the support toward the operating instrumentalities the machine is started and operates automatically throughout the cycle, the support being moved into operative position, held there during the operation of the operating inst-rumentalities, and then returned to its initial position.` Preferably and as illustrated, the Work support is provided With a pluralityef positioning devices such, for example, as jig pins arranged to be received by jig holes formed in the heel-seat portion of the sole to be operated on to locate the shoe in predetermined relation to the support and, after movement of the support into operative position, to assist in locating the shoe in operative relation to the operating instrumentalities. As illustrated, the machine is provided With means to engage the jig pins and adjacent portions of the sole to locate the support and clamp the shoe thereon. l

rlhe operating instrumentalities of the ilinsti-ated machine include knives movable the sole and vvelt from the shoe upper.

transversely of the rea-r portion of the sole i the sole and Welt during theaction of the knives, crease plates are provided which engage the shoe in the 1Welt crease adjacent to the knives, the crease plates preferably having edges Which act to sever the inseam stitches Which hold tlie Welt, shoe upper and` insole Athereby freeing the severed portion of In the illustrated machine, the knives andcrease plates are arranged tomove in paths curved to correspond substantially to the transverse curvature of the shoe bottom in proximity to the breast line, the axes of said paths being beneath the shoe and extending generally lengthwise of the shoe. In operating upon the soles of shoes Where it is desired to form heel-breast receiving shoulders which are inclined at a small angle to the longitudinal median lineof the soles in order that the shoulders Willbe complemental to the breasts of heels, Which breasts are curved transversely of the heels, these axes which are generally lengthwise of the median plane of the shoe may be inclined slightly relatively to said plane. Also, as illustrated, means is provided for imparting to the crease plates and knives a conjoint movement in the paths indicated, With means for interrupting the movement of the crease plates, after the c-rease plates have been moved into engagement With the shoe, and permitting the knives to move beyond them to make the required cut upon the end portion of the sole and Welt. Preferably means is provided for maintaining the crease plat-es in engagement With the shoe after their movement With the Although the invention is described as bechine, it is recognized that the invention isv `ing embodied in a sole and Welt cuttingmav ico V ment thereof and will be pointed out in the appended claims.V

A2, the illustrated sole and welt cutting ma- Y chine comprises a head 10 mounted upon a base 12 and having a pair of forwardly eX- tending lugs 14 to which is pivotally mounted at 16 arshoe supporting jack 18. A pair of jig-pins 2O are carried by the jack 18 and located and spaced to pass through jig-holes 200 formed in the heel portion of a shoe such as a welt shoe having a short soleto present the rear ends of the sole and welt invariably in predetermined relation to the operating instrumentalities of the machine. In order to assist the operator in removing a shoe from the jig-pins 20 after the shoe has been operated upon, an ejecting plunger 22 is provided which is operated by a hand-lever 24 carried by the iack 18. The hand lever is fulcrumed in the ack 18 at 26 and may be depressed b v the operator against the action oi aA spring- 28 to force the plunger 22 upwardly against nthe shoe between the `iig-holes 200. i*

A starting lever 32 mounted onl a shaft 84 supported by suitable bearings in the head 1() ofV the machine carries a spring-pressed plunger 36 arranged to engage a shoulder 38 formed on a one-revolution clutch 40 of any suitable type and acts to hold the clutch out ot engagement with a constantly running worm-wheel 42 loosely mounted upon ashaft 52 having suitable bearings in the head 10 of the machine. Motion is imparted to the worm-wheel 42 from a motor 50 through a coupling-48, shaft 46,'and worm 44V. A cam block 58 fast to the shaft 52 has a cam groove 56 formed thereon for engaging a cam-roll 54 carried by the lever 32 and acts during` each revolution of the cam to rock the lever 32 into clutch releasing position. The jack 18 and lever 32 are connected by means of a link 30 one. end of which is pivotally connected at 60 to the lower end of the lever 82 and the other end to the jack 18 at 62. The configuration it the cam groove 56 is such that the lever may be moved in a countercloclwise direction as viewed in. F 1 by movement ot the jacle 85 18 toward its operative position, thus disengaging the plunger 36 from the shoulder 38 and allowing the clutch 40 and the shaft 52 to make one revolution. Rotation of the shaft 52 causes the cam groove 56 to engage 9 the jack 18 against further movement dur- 9 ing the sole and welt-cutting operation.

After the pick 18 has been moved into operative position (Fig. 2) means is provided for yieldingly clamping the shoe upon the jack and for engaging` the jig-pins 2O to hold the shoe in position during the sole and welt cuttingoperation. rThe clamping means comprises a pair of plungers 68. 7 O carried by a pair of vertically movable sleeves 64, 64. mounted in the head 10 of the machineabove the jack 18 and movable with the plungers 68, 7() into and out of work-engaging position by means hereinafter described. Reduced ends 72. 74 of the plnngers 68, 70 eX- tend through the sleeves 64, 64 and have their upper ends threaded to receive usting nuts 78 and lock-nuts 80. Surrounding the reduced ends '-2, T4 of the plungers 68, 70 are coiled springs 76, Z6 bea-ring at one end.

against shoulders 82, 82 formed on the sleeves 64, 64 and at the other end against shoulders 84, 84 on the plungers 68. 70. Fast to the shaft 52 is a cam block 86 (Figs. 1, 2 and 4) having a cam groove 88 formed on one face thereof for engaging a cam-roll 90 (Fig. 3) carried by a downwardly extending arm 92 of a bell-crank lever fulcrumed on the shaft 84 and having its other arm indicated at 96, this arm 96 extending forwardly and carryin g a near segment 98 meshing with a pinion 100 (Figs. 1, 2 and 3). The pinion 100 meshes with teeth'102- 4) formed upon the sleeves 64. 64.v T he cam groove 88, by its contour maintains the sleeves64, 64 in their uppermost positions until the jack 18 is moved into operative position (Fig. 2) and then moves the lever 94 in a clockwise direction, as viewed in Fig. 2, to lower the sleeves 64, 64 by rotating the pinion 100. The d ownward movement of the sleeves 64, 64 continues until the work-engaging surfaces 104, 106 (Figs. land of the plungers 68, come in contact with the end portion of the sole of a shoe and the heel-seat portion of the shoe respectively,.the jig-pins 20 entering vertical openings in the plungers 68, 70. The downward `movement of the sleeves 64, 64 continues, compressing the springs 76 and holding the shoe 300 firmly upon the jack 18. The movement of the angle lever 92, 96 is then reversed elevating the sleeves 64, 64 to free the shoe upon the ack 18, The work-engag-.

ing surface 104 of the plunger 68 is curve( to correspond approximately to the transverse curve of the last at the heel-breast line and has laterally extendingears 107 4) having knife-guiding .surfaces 108 (Fig.

V1) formed thereon to guide cutting knives 114, 114 during the operation.

Located upon opposite sides of the jacl: 16 are sole and welt cutting units 110, 110 (F1 3) secured by bolts 111 to finished surfaces 113, 113 formed on the outer face of the head 10 of the machine. The surfaces 113. 113 are inclined relatively to each other and to the longitudinal meoian line of the jack 18 to position the units 110, 110 so that dis.;- cntters 114, 114 will cut the sole of a shoe to sole and welt cutting O. La.

form heel-receiving surfaces 115, 115

8) variably at a predetermined angle to the line determined by the jig-pins 20 and at a` fixed distance therefrom when the pins are in operative position. Since these units 110, 110 are. of similar construction only one of yhem need be described. The right-hand sole and welt cutting unit 1.10, as illustrated in Fig. 4,'has its cover-plate 112 removed. to show the relative positions of the disk-cutter 114 and crease-plate 116 when the machine is at rest. Each unit 110 has a circular groove 118 formed therein for receiving segmental members 120, 122. The members 120, 122 are free to move in the groove 118 and are connected bymeans of a toggle comprising links 124. 125 pivoted to each other and having their free ends pivoted respectively to the members 120, 122. The link 125 of the toggle has a projection 126 normally engaging the upper 'surface 126 of an adjustable cam piece 130. The cam piece 130 hasa raised surface 132 adapted to the projection 126 of thetogg'le link 124 to break the toggle.) The cam piece 130 is secured to the unit- 110 by s'rews 134 extending through slots 136 in the unit 110 so that by loosening the screws the cam piece 130 may be moved along the path of the projection 126 an dthen clamped in adj usted position to vary the point in the conjoint movement of the segmental members broken. a spring-pressed plunger 151 carried by the `120, 122 when the` toggle 124, 125 willbe ,broken and` relative movement of said mem'- bers. permitted.

. A link 138 (Fig. 7) is pivotally connected i to the member 120 at 142 and has the diskcutter 114 pivotally connected at 140 to its forward end.` The member 120 is slotted at A144 to receive the link 138 and has an over- -the shoe upper. The segmental member-122 has a friction device 150 which bears against the inside surface 152 of the cover-plate 112 A(Fig.v 3) and acts to maintain the creaseplate 116 in engagement with the shoe in the crease, between the shoe upper and the welt, after the toggle connection 124 has been The friction device 150 consists of segmental member 122 and bearing against lthe inside surface 152 -of the cover-plate' 112.

Fixed tothe shaft 52 is a cam 154 (Figs. 1, 2, 3 and 4) having a groove 156 formed thereon an d engaging a cam-roll 158 carried by a lever 160 loosely mounted upon a shaft 162 having bearings in the head 10 of the machine. "A similar O'roove is formed upon the outer surface of the cam 86 engaging a cam-roll 159 carried bythe left-hand lever 160 (Fig.

.Formed on the outer extremity of the lever 160 are gear teeth 164 engaging an elongated pinion 166 the teeth of which mesh for a portion of the length with teeth 168 formed on the outer surface of the segment 120 (Fig. 4). In order that the pressure existing between the driving gear teeth 164 and the driven pinion 166 will not cause the gear teeth 164 to olii .b upon the teeth of the pinion 166, a bearinsY roll 170 (Fig. 3) is rotatably mounted in the Vhead 10 of the machineupon a stud l 1? 2 and engages a finished surface 174 of the lever 160 in the plane of the axes` of the pinion 166 and lever 160. ,y

The configuration of the cam groove 156 is such that the lever 160 is first moved in a clockwise direction (Fig. 1) to move the segmental member 120 upwardly in a counter` clockwise direct-ion (Fig. 4) by rotation of the pinion 166. Upward movement of the member 120 causes the member 122 to move in the same direction through the toggle connection 124, 125. When, however, the creaseplate 116 engages the shoe between the shoe Lipper and the welt the raised' portion 132 of the cam 130 contacts With the projection 126 formed on the link 125 of the toggle 124, 125 and interrupts the conjoint movement of by releasing the member 120, 122. The friction device 150 holds the crease-plate 116 in engagement with the shoe while the member 120 continues to v iove upwardly causing the disk-cutter 114 movement thereof. The knives 114, 114 bear against one side or shoulder of the grooves 17 6, 176, thev shoulder of the grooves forming straight edges against which the sharp edges of the knives work during the cutting operation. Thus a pair of shear couples are formed for trimming the surplus material from the rearward portions of the sole and welt. Mounted upon the shaft 162 is al brakelever 178 (Fig. 2) having leather covered Vface 180 for engaging the outer surface 182 of the cam 58. A spacing bar 184 extending between the opposite sides of the head 10 has an Voperifig 186 formed thereon to receive one end of a coil spring 188, the other end of which extends into an opening 190 in the lever 178. An adjustablel set screw 192 is threaded into the upper portion of the lever 17 8 and may be locked in adjusted positionv by a lock-nut 194. rEhe end of the set-screw 192 is engaged by a surface 198 formed on the lever 32 to move the brake-lever 178 out of engagement with the outer surface 182 of the cam 58 when the jack 18 is moved toward its operative position. i

In the operation of the machine, the operator mounts a shoe 300, with the heel-end of the last removed, upon the shoe supporting jack 18, the pins 20 entering jig-holes 200 formed in the rear portion of the shoe, and moves the iack 18 toward its operative position. Movement of the jack y18 toward its o} 3erative position causes the lever 32 to move in a counter-clockwise direction (Fig. 1) through the connecting link thereby disengaging the plunger 36 from the shoulder 38 formed on the 'clutch 40, the surface 198 of the lever 32 engaging the end of the ustable set-screw 192 therethe brake-lever 17 8 and allowing the clutch member 40 and shaft 52 to make one revolution. Vlhe iirst result of the rotation of shaft 52 is the movement of the jack 18 positively into operative position due to continued counter-clockwise movement being imparted to the lever 32 bv the contour of the cam-groove 56. The configuration of the cam-groeve 56 is suchr that the jack 18 is locked in operative 'position during the sub- After the jack 18 has been mov-ed into operative position the angle lever 92, 96 is moved in a clockwise direction by the cam track 88 in the block 86, thereby lowering the sleevesik 64, 64 and plungers 68, 70 yieldingly to clamp lthe shoe upon the jack 18 and to engage the nism described, causing the crease-plates 116,-

116 to engage the shoe at opposite sides thereof between the shoe upper and the welt, then moving the disk- knives 114, 114 toward each other and relatively tothe crease plates 116, 116 to remove the surplus stock from the rear portions of the sole and welt rearwardly of the heel-breastline; and then returning the crease- plates 116, 116 and disk cutters 114, 114. to their initial positions (Fig. 4). During the sole and welt cutting operation the'- cutters 114, 114 are guided by grooves 176 in the crease vplates 116, 116 and surfaces 108, 108 formed on the plunger 68. The angle lever 92, is then moved in a 'counter-clockwise direction elevating the sleeves 64, 64 andy freeing the shoe upon the jack and moving the plungers 68, out of engagement with the iig pins 20. The jack 18 is then moved outwardly into its inoperative position by the return of the lever 32 into clutch releasing position by the cam-groove 56. Movement of the lever 32 into clutch releasing position allows the brake-lever 178 to engage the outer surface 182 of the cam 58, thereby preventing overthrow of the parts and insuring that the cams will stop in their initial positions. The operator then depresses the lever 24 to move the pin 22 upwardly and remove the shoe 300 from the ack 18.

lt will be apparent from the foregoing de! scription that the operation of the machine relieves the operator from the responsibility of positioning the shoe accurately relatively to the operating instrumentalities of the machine, the only task of the operator being toremove and replace the shoes and to initiate the movement of the shoe support toward its operative position.
