ENGLAND, ASSIG-NORS TO UNITED SHOE MACHINERY CORPORATION, OF PA'IERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY HEEL-SEAT FITTING MACHINE Application filed.- September 24, 1928, Serial No.
This invention relates to machines for use in the manufacture of shoes and is illustrated herein as embodied in a heel-seat fitting machine.
In the manufacture of womens shoes having wood heels, for example, surplus material is trimmed from the heel-seat portion of a sole attached to a shoe in order to provide a seat which will receive the cupped or concave portion of the attaching face of the heel and to insure that the rim of the attaching face of the heel will bear snugly against the overlasted margin ofth-e counter portion of the shoe upper.
Good shoemaking requires that a wood heel shall be firmly secured to the heel-seat portion of the shoe and that the margin of the sole shall be completely concealed by the engagement of the rim of the attachin face ofthe heel against the shoe upper. Moreover, the junction of the sole and heel at the heel-breast line must be inconspicuous and the union of the parts must be smooth and neat in appearance.
In trimming the heel portion of the sole for the reception of a wood heel it is the usual practice to reduce the width of the sole rearwardly of the heel-breast line and to form shoulders substantially at the heel-breast line of the sole against which shoulders the breast of the heel abuts. This operation is preferably performed after the sole is attached to the shoe upper, the sole-attaching stitching preferably extending a short distance rea-r wardly of the heel-breast line of the sole, leaving the rear portion of the sole loose from the shoe upper. V
In carrying out the heel-seat fitting operation in machines of the drag-knife type it is customary to distort the sole so that its marginal portions are curled away from the shoe upper, the drag-knife severing the curled marginal portions as it trims and bevels the sole. A heel-seat fitted by the distortion method generally has its marginal portions beveled at a relatively slight inclination to the heel-attaching surface of the sole. In some types of shoes, however, the sides of the cupped attaching faces of the heels to be secured to the shoes are inclined 307,937, and in Great Britain October 1, 1927.
at steep angles to the bottoms of the attache H ing faces. In order to form heel seats shaped toreceive heels such as arejust described, it is desirable considerably to distort the rear portion of the sole. 'VVhen the sole is greatly distorted during the trimming operation the stitches attaching the sole to the shoe upper are often strained and weakened, or even pulled out, in the vicinity of the heel-breast line so that the sole is in danger of pulling loose from the shoe upper at the heel-breast line. This permits heel-breast receiving shoulders which areformed at the breast line to sag orgap away from the shoe upper after the shoe'has been Worn a short time. I
It is an object of the invention to provide a inachine of the drag-knife type for fitting heel-seat portions of soles while the soles are in an undistorted condition.
' A. further object of the invention is to providea heel-seat fitting machine of the dragknife type for trimming the heel-seat portions of soles which already have been attached to shoes without cutting the stitching between the soles and the shoe uppers rearwardly of the breast line and without loosening the stitching in the vicinity of the heelbreast line.
lVith these objects in view a feature of the inventionas embodied in the illustrated machine comprises the combination of a shoe support, crease plates or jaws constructed and arranged to enter the rand crease of a shoe on the support, and beveling knives for trimming the marginal portions of the sole of the shoe lengthwise of the shoe to reduce the heel seat portion thereof to [it the attaching face ofa wood heel, said knives being inclined transversely of the heel-attaching surface of the sole. An advantage of this feature is that beveling knives of different inclinations v on ation of the beveling knives and at the same time to form heel-breast-receiving shoulders upon the sole, the machine, in accordance with a further feature of the invention, is provided with the above-mentioned jaws for supporting the lateral portions of the rear portion of the sole, one of the jaws being movable toward and away from another jaw, and a cutter movable with the movable jaw and also movable relatively to said jaw and constructed and arranged to form a heel-breastreceiving shoulder upon the sole while the sole is undistorted. The shouldering knives are mounted for rectilinear movement transversely of the sole of the shoe, said knives being inclined to the attaching surface of the sole transversely of the sole substantially at the same inclination as the beveling knives to form shoulders substantially at the heelbreast line of the sole. The shoulder-forming knives of the illustrated machine are sprung against the forward edges of the crease plates and when inclined to the crease plates as illustrated cooperated with the forward.
edges of the crease plates to constitute shear couples which form heel-breast-receiving shoulders upon the sole.
In accordance with another feature of the invention the illustrated machine is provided with a pair of sliding beds for carrying the beveling knives and the shouldering knives as well as the crease plates, the sliding beds being constructed and arranged to move toward and away from one another, and the beveling and shouldering knives also being mounted for relative movement with the sliding beds and the crease plates.
Another feature of the invention as embodied in the illustrated machine is a crease plate provided with a thin finger portion constructed to enter the rand crease of a shoe without distorting the sole of the shoe, said crease plate also having in its sole-engaging surface a guideway in which one of the beveling knives is arranged for movement.
A further feature of the invention includes a novel shoe-positioning construction including a back gage which is regulated by a device for engaging a heel similar to the heel which is to be placed upon the shoe to be operated on, the back gage being constructed and arranged to position the shoe lengthwise in the machine by contact with the rear portion of the shoe upper. The heel engaging device is set by the heel and comprises abutments adapted to engage the opposite sides of the heel to position the same widthwise, and members to engage the rear and the breast of the heel to position the heel lengthwise, the abutments being constructed and arranged to centralize the heel widthwise prior to the lengthwise positioning of the eel by the abutments. The heel-engaging device and the back gage are illustrated herein as provided with means for urging the heel-engaging device against the heel and the back gage against the rear portion of the upper of the shoe and as also provided with means for locking the heel in position in the heel-engaging device and for locking the back gage against rearward movement when it is engaged by the shoe upper.

Fig. 13 is a perspective view of a modified form of crease plate.
For purposes of illustration it will be assumed that the shoe being operated upon is of the well-known McKay type and that said shoe is to have its heel-seat trimmed for the reception of a Cuban heel. The shoe shown in Fig. 11 has its sole-attachingseam A extending along the shank portion 13 of the shoe to points somewhat rearward of the breast line. C of the sole of the shoe. The heel-seat portion of the sole F of the shoe may be loose rearwardly of the ends of the stitching or it may be held by a central tack l). The rear portion E of the sole F terminate-s a considerable distance from the rear of the shoe and is what is often termed a short sole.
The heel-seat portion G of the sole F of the illustrated shoe is trimmed along its marginal portions lengthwise of the sole of the shoe afterthe sole has been. attached to the shoe to form steep bevels H which may, if desired, be of such a steep inclination relative to the heel-attaching face W of the heel-seat portion of the sole of the shoe as not to pierce the line of stitches A rearwardly of the heel-breast line C. The heelseat is also trimmed to form a pair of heel-breast receiving shoulders K extending laterally of the sole at its heelbreast line.
The rear portion of the heel-seat of the sole illustrated in Fig. preliminary trimming prior to its application to the shoe upper, the margin to the rear of lines Pbeing trimmed to form a U-shaped portion Q, somewhat longer than the parallel-sided portion N of the sole of the shoe shown in Fig. 11. The-heel-seat portion of the sole illustrated in Fig. 12 is, from the lines P forwardly, of the same form as the heel-seat portion. of the shoe illustrated in Fig. 11.
The illustrated machine, which will later be described in detail, comprises a support for holding the shoe to be trimmed, which shoe is supported with its sole uppermost and its heel away from the operator, mechanism for arranging th shoe in proper position in the machine so that the trimming operation may be performed, a pair of knives which form the bevels H on the heel-seat portion G of the soleof a shoe and a pair of knives for forming the heel-breast receiving shoulders K.
The machine as a whole includes three principal groups of in-strumentalities carried a lower head 2, a middle head 4 and a top head 6, respectively. The lower head 2 carries the shoe-supporting means and forms a base for the middle head a and the top head 6. The middle head t carries soletrimming mechanism and the mechanism therefor while the upper head 6 carries heelgaging mechanism by which the position of the shoulders K is determined.
The lower head 2 carries a forwardly extending horizontal bracket 8 having a T- shaped horizontal guideway 10' extending forwardly and rearwardly of the machine.
12 has been given a Slidingly mounted in the guideway 10 is a work support or jack 12 (Fig. 1) having a T-shaped base 14 (Fi 3) slidingly mounted in the guideway 10 so that a shoe mount- M recess 26 which receives the threaded shank h portion 28 of a shoe-supporting plate 30 (Figs. 1 and fixed in adjusted position relatively to the post by a nut 32 upon the shank portion of the shoe-supporting plate A spring 3% is located within the recess 26 of the post 20, the ends of which spring engage against the pin 24 and the lower end 36 of the shank 26 of the shoe-supporting plate 30, normally to hold the post 20 in the raised position shown in Fig. 1.
As will later be brought out, when the sole of the shoe is being trimmed the post2O is in lowered position relatively to the vertically extending portion of the work support 16, as shown in Fig.4. in order to hold the post 20 in raised position while the shoe is being trimmed, an arm 38 (Figs. 1 and 4t) pivoted for movement about pin 40 mounted in the forwardly extending horizontal bracket 8 is raised upwardly through a slot 42 (Fig; 2) in the bracket 8 and a slot 44 in the work support 16 into contact with the lowerend 46 oflthe post 20. The forward end of the arm 38 is normally held downward by a heavy spring 48 which is connected to the arm at its forward portion 50. Pivoted about the in 40 is'also a forwardly extending dog 52 which is carried with but movable relatively to the arm 38 by a spring 54, the dog being adapted to engage a rack 56 at the under part of the work support 12 to hold the work support from sliding forward when the shoe is having its heel-seat trimmed.
The rear portion 58 of the arm 38 is con nected by a link 60 to one end of a floating lever 62 the other end of which is pivoted to a plunger 64- which through associated mechanism hereinafter described operates a pair of crease plates or jaws 66 which are arranged to enter the rand crease of the shoe to be operated on as far as the line of stitching A between the shoe upper and the sole. The floating lever 62 is connected at its central portion to a rod 68 (Fig. 1), which extends downwardly to a treadle 72.
The middle head 4 is provided with bearings one of which is shown at 74 (Figs. 1 and 3) for supporting a forwardly and rearwardly extending driving shaft 76. A cam 78 having cam grooves 80, 82 is mounted upon the shaft 7 6 to actuate through other mechanism which will later be described beveling knives or blades 84 which are moved lengthwise of the sole to trim the marginal portions H of the heel-seat portion of the sole as well as shouldering knives or blades 86 which are moved transversely of the sole to form heelbreast receiving shoulders K.
The middle head 4 has on each side thereof and extending laterally therefrom a pair of brackets 88 (Fig. 2) spaced from one another, each pair providing a guideway 90 extendin parallel to the front of the machine and slidingly supporting and guiding two laterally movable sliding beds 92, the guideways on opposite sides of the machine be ing in the same horizontal plane and in line with one another.
Since the sliding beds 92 with their ass0- ciated parts are the same on both sides of the machine, it will be necessary to describe but one side, it being understood that the side opposite that described has a reversed but corresponding part. Each of the sliding beds 92 carries one of the shouldering knives 86, one of the beveling knives 84 and one of the crease plates 66. and upon the under side of each of said sliding beds there is a boss 94 in which is fixed a depending stub 96 (Fig. 3) the lower end of which is pivoted at 98 to the outer end of a link 100, the other end of the two links being connected at 102 to the plunger 64 which is mounted for vertical movement in a bearing 104 in the lower head 2 of the machine. The lower end of the plunger 64 is connected to the floating lever 62 already described, the mechanism being constructed and arranged so that downward pull on the plunger rod will move the sliding beds 92 toward one another in the guideways 90 in the middle head 4 of the machine.
The lower end of the plunger rod 64 has a lug 106 1) extending forwardly therefrom, which lug is provided with a hook 108 to receive the end of a spring 110 the other end of which spring is connected to the lower head 2, the spring serving to keep the plunger rod 64 in a raised position which results in holding the sliding beds 92 at their extreme positions away from one another in the guideways 90.
The illustrated machine is also provided with a holddown clamp 112 which serves to engage the heel-attaching face of the sole of the shoe between the beveling knives 84 (Fig. while the sole is being trimmed in order to assist in tightly securing the sole against movement during the trimming operation. The holddown clamp is pivoted at 114 (Fig. 1) to the top head 6 through an arm 116 which is connected near its central portion 118 to a downwardly extending clamp-actuating rod 120 which passes through the forwardly extending lug 106 on the plunger rod 64. The clamp-actuating rod 120 is provided with a pair of collars 122. 124 the former of which serves to confine a spring 126 between itself and the forwardly extending lug 106 and the latter of which is adapted to be engaged b the lug 106 when the plunger rod is lowere As the plunger 64 is lowered to draw the sliding beds 92 and their crease plates 66 together it will depress the rod 120 and cause the holddown clamp 112 to engage the bottom of the sole of a shoe as shown in Fig. 4. A turn buckle 128 upon the rod 120 may be used for varying the amount of pressure with which the clamp will engage the sole of the shoe and the time at which such engagement will occur.
The crease plates 66, which are located at the forward inner corners of the sliding beds 92 and which assist in maintaining the sole in position to be trimmed just above their level (Fig. 4), are strong enough to resist the upward pressure of the work sup ort and include thin finger portions 130 ig. 8) adapted to enter between the shoe upper and the sole at the side of the heel-seat of the shoe. The upper surfaces of the crease plates 66 are provided with knife guideways 132 for receiving the beveling knives 84, said guideways being formed by the shoulders 134 extending lengthwise of the plates and the flat surface portions 136 which also extend lengthwise of the plates and serve to cut away part of the thickness of the crease plates to provide the fingered portions 130. The beveling knives 84 are adapted to move in the guideways along the angled portions 138 formed by the shoulders 134 and the flat surface portions 136 as shown in Fig. 8. The sliding beds 92 may be attached to the crease plates or jaws ()6 in any convenient manner such as that shown in Figs. 3 and 8 in which each plate includes a tongued portion 140 and two threaded bolts 142 which may be fastened to the inner side 144 (Fig. 3) of the sliding beds 92. Although the crease plates or aws and the sliding beds have been illustrated as separate parts, it will be understood that each sliding bed which supports one of the knives 84 and one of the shoulder forming knives 86 is rigidly attached to one of the crease plates and is, in effect, a part thereof.
Each sliding bed 92 is provided near its front margin with a laterally extending horizontal guidewa-y 146 (Fig. 2). A knife carrier slide 148 is mounted for reciprocation in each guideway 146 and has fixed to it a downwardly extending rod 149 3) which is adjustable lengthwise of the slide in a slot 150 (Fig. 2) by means of a nut 152 threaded upon the upper portion 154 of the rod so that the initial position of the slide 148 in its guideway 146 may be adjusted, the downwardly extending rod 149 retaining a fixed position with respect to the 7.
knife carrier slide148during the operation of the machine.
The lower portion of each downwardly extending rod 149 passes through a'bifurcated portion 156 (Fig. 2) of an arm 158 which has a sleeve portion 160 mounted for turning movement upon the depending stub shaft 96 attached to the sliding bed 92. Mounted-on each sleeve 160 is another arm 162 extending laterally of. the machine, the'end of which is pivoted to alink 164 extending rearwardly of the machine and pivoted to a cross-head 166 (Fig. 1) which is attached to a slider 168 adapted to, slide forwardly and rearwardly of the machine in a guideway 170 in the frame of the machine, the slider: 168 carrying an upwardly extending roller 172 positioned in the cam groove 80 of the cam 78.
. It will be clear that asthe cam 7 8 is rotated and the cross-head 166 moved forwardly and rearwardly of the machine the knife carrier slides 148 will be moved laterally of the machine on the sliding bed 92. Since the connecting link 164 is of considerable length,
movement of the sliding bedstoward and away from one another does not affect, to any harmful extent, the position of the knife carrier slide 148 relatively to the sliding bed 92. i
The knife carrier slides 148 are eachprovided with an upwardly extending lug 174 having a cylindrical recess 17 6 (Fig. 3) with its axis parallel with the direction of movement of the knife-carrying slides 148. A
knife carrier 17 8 has ac lindrical shank ortion 180 received by the cylindrical recessed portion 17 6 of each upwardly extending lug 17 4 and is held in place therein by a bolt 182 passing through the cylindrical bored portion. The knife carrier 178 is also provided with a portion 184 which extends forwardly of the machine and toward the center of the machine and includes a T-shaped groove 186 which receives the thin fiat knife blade 86 and a clamping piece 190 T-shaped in cross-section which is inserted in the T-shaped groove forward of the knife 86, the knife being held in position in the knife carrier by a screw 192 passing through the T-shaped clamping piece 190, the knife 86 and entering the rear face 194 of the forwardly extending portion of the knife carrier so that the thin flat knife blade 86 may be clamped between the bottom of the groove 186 and the clamping piece 190.
The construction and the arrangement of the parts above described is such that in operative position (Figsrl and 2) the knife or blade 86 extends; downwardly and forwardly of the machine at an angle of about degrees to the horizontal, the plane in which the knife lies being parallel to the axis of the knife carrier cylindrical portion 176. In order that each of the knives 86 will trim the sole along its heel-breast line C as far as the line L (Figs. 11 and 12) to form one of the shoulders K but will not pass the cutting path of the beveling knives 84 at some points more than others the lower cutting edge 196 (Figs. 5 and 6) of each of the knives 86 is constructed atright angles to the sides 198 of the knife and is arranged higher at its inner corner 200 than at its outer corner 202.
As shown in Fig. 2 the knives 86 move along the front edges 204 of the crease plates 66,'which front edges, extend parallel with the direction of the movement of the knife carrier slide 148, the knives 86 thus being supported against rearward springing by said crease plates. Since the lower cutting edge 196 of each of the knives 86 which engage the upper forward edges of the crease plates is disposed at an angleto the horizontal, as illustrated, each of the knives will cooperate with the upper forward edge of its respective crease plates 66 to constitute a shear couple which will effectively form heel-breast-receiving shoulder K. Although each of the knives is illustrated as having its cutting edge arranged to form an acute angle with the upper forward edge of its respective crease plate thus producing the desired shearing cut to form the heel-breast-receiving shoulder, it will be understood that the cutting edge may be arranged at various angles with reference to the upper forward edge of the crease plate.
In order. to support and guide the beveling knives 84, each of the sliding beds 92 has a raised portion 206 (Fig. 3) the under side of which has a horizontal dovetailed guideway 208 which extends forwardly and rearwardly parallel to the center of the machine and in which a knife carrier 210 is mounted for movement forwardly and rearwardly of the machine. The upper surfaces of the rear ends 'of the knife carriers 210 (Fig. 8) are provided with transverse slots 212 receiving a cross-head 214 which is constructed and arranged to move both knives together and to allow the knife carriers 210 to be moved toward and away from one another as'the slid ing beds 92 are moved toward and away from one another, without causing any relative a dependingcamroll 218 that engages the.
cam groove 82 in the cam '7 8. Upon rotation of the cam 7 8 the dovetailed slider 216, through the cross-head 214, moves the knife carriers 210. forwardly and rearwardly of the machine to bevel the marginal portions of the heel portion of the sole in a direction extending lengthwise of the shoe.
The under surface of each knife carrier 210, along its inner margin 222 (Fig. 8), is beveled to slope toward the center of the machine and upwardly at a steep angle to the horizontal. A knife 84 having an elongated portion with a beveled cutting edge 224 and a flanged portion 228 is fixed to the front face 226 of the knife carrier 210 by means of the flange 228 which is screwed against the said front face 226 of the knife carrier, the knife thus extending forwardly of the knife carrier and having its beveled edge 224E extending laterally of and forming a substantial angle with the flat surface portions 136 of the crease plates and the heel-attaching face of the sole. It is obvious that the angle which the cutting edge of the knife makes with the surface of the sole may be changed as desired, such change being brought about by attaching knives of different angles to the knife-carrying slides.
Since the knives 84 travel in the knife guideways 132 with their cutting edges 224 inclined at an angle to the crease plates 66 and the bottom of the sole, and said knives have their corners 230 moving along the corners 138 of the crease plates, as shown in Fig. 5. it will be clear that the finger portions 130 of the crease plates 66 will extend far enough between the sole F of the shoe and the shoe upper M to protect the upper from being cut by the knives, and the knives will be prevented from springing relatively to the plate as they trim the lateral marginal portions of the sole in the general direction of the length of the shoe.
The lower cutting edge 196 of the shouldering knives 86 are inclined to the heel-attaching face of the sole transversely of the sole substantially at the same inclination as the cutting edges of the beveling knives 84 so as to form a clean cut shoulder at L, the knives being arranged so that they will not substantially cross the paths of one another.
The shaft for rotating the cam 78 which operates the beveling and shouldering knives is actuated by a one-revolution clutch 232 mounted at the rear of the machine and thrown into operation by the hand lever 234:.
In order to position the shoe lengthwise in the machine so that the beveling knives and the shouldering knives will operate at correct positions on the sole to form the required heel-seat, mechanism is provided whereby rearward movement of the shoe to be operated upon is halted by contact of the counter portion R (Fig. 4) of the shoe upper against a back gage 282 having a concaved front face 284, the position of the back gage being determined by a heel-engaging mechanism adapted to receive a heel similar to the heel which is to be attached to the shoe. The back gage 282 includes a sliding support 286 (Fig. 1) which is freely slidable forwardly and rearwardly of the machine in a guide- Way 288 of the middle head 4.
The top head 6 carries heel-engaging and locating mechanism which serves to regulate the position of the back gage 282. For this purpose the sliding support 286 has rigidly fixed thereto an upwardly extending post 290 having its upper end connected to a traveler 292 which slides forwardly and rearwardly of the machine in a guideway 294. An upstanding post 296 is connected to the traveler 292, said post having a threaded hole 298 extending parallel to the length of the slider and receiving a screw 300 having a knurled head 302 at its rear end. The front end of the screw 300 is provided with a collar 304 that lies in a recess 306 (Fig. 2) near the rear of a rear gage plate 308 having a curved recessed portion 310 adapted to engage the rear portion of a heel.
The front of the top head 6 carries a breast gage 312 arranged to engage the breast T of a heel (Fig. 1) which gage is slidably mounted forwardly and rearwardly of the machine in a guideway 316 (Fig. 2) for initial adjustment. The initial adjustment of the gage is effected by means of a screw 318 which passes through an upstanding threaded recess in an upwardly extending portion 320 of the breast gage, said screw being mounted for rotation in an upwardly extending lug 322 on the top head 6 and being provided with a knurled head 324 for conveniently carrying out the initial adjustment of the breast gage.
The top head 6 is also provided with a pair of horizontal guideways 326 positioned laterally of and between the rear gage plate 308 and the breast gage 312 and extending toward the center of and forwardly of the machine. In order to engage the sides S of a heel to center the same. the heel-engaging mechanism includes clamp slides 330 which are adapted to be moved in the guideways 326, each clamp slide carrying clamps 332 connected to the clamp slides 330 by screws 334. The inner ends 336 of the clamps 332 are inclined upwardly and toward one another at an angle of about 75 degrees to the hori zontal and preferably carry clamp pieces 338 of rubber or leather so that they will not damage the cover of the heel.
Projecting downwardly from the clamp slides 330 are pivot pins 340 connected by links 342 to other pivot pins 344 that pro]ect upwardly from a heel clamp actuator 346, the arrangement and positions of the parts being such that when the clamp sIides 330 are in their outermost position the links 342 will appear as a straightened toggle and when the clamp slides are in their innermost position the links appear as a broken toggle as shown in Fig. 2.
The under surface of the rear gage plate 308 and the upper surface of the heel clamp actuator 346 are provided with racks 348, 350 respectively (Fig. 1) which engage a 1 head 4.
In order to position the shoe correctlyin the machine for the performance of the heelseat fitting operation, mechanism is provided for engaging the heel which is to be attached to the shoe to be'operated on, or a heel like that heel, which mechanism controls the back gage 282 against which the shoe upper is positioned, to determine the extent to which the heel-seat portion of the sole will be' trimmed. 'Provision is also made for normally urging the heel-engaging means in contact with the heel andfor urging the back gage forwardly of the machine. Means 1s also provided to lockfthe back gage against 5 rearward movement under pressure of'the' shoe, this locking means beingadapted to hold the back gage in its foremost position and to hold the heel-engaging means against the heel.
Keyed to the *outer end of the rock shaft 364 is a hub 366 (Fig. 9) carrying an upright arm 368 having a yoke portion 37 0 (Figs. 9 and 10) in which is mounted a pawl pin 372.
' Extending axially from the hub 366 are a pair of projecting lugs 374 which are adapted to be engaged by a pair of axiallyextending lugs 376. upon alever 378 loosely mounted upon the rock shaft 364. A treadle rod 380 is pivoted to the lever 378 and forwardly ex- '40 tending from said lever 378 is an arm 382 carrying a spring 384 for holding the arm 382 normally in a downward position. Clockwise movement of the arm 382 through mechanism carried by, the yoke 370, which mechanism will be later described, causes the up-- right arm 368 to move in a clockwise direction (Fig. 10), thereby moving the compensating block 354 toward the front of the machine. Conversely upon depressing thetreadle rod 380 the lugs 376 abut against the lugs 37 4 'rotating the upright arm 368 in a counterelock wise direction therebymoving the compensating block 354rearwardly of the machine, the compensating block carrying with it the pinion 352 which engages the rear gageplate 308 and the heel clamp actuator 346 to move these two parts rearwardly. of the machine. Rearward movement of the heel clamp actuator 346 causes the clamps 332 to move away from one another by reasono f the toggle ac-' tion of the links 342. Theclamping means for holding the heel in the heel-engaging means are thus opened to permit anew heel to be inserted, which heel is placed with its attaching face downwardly upon the top surface 386 of the horizontal plate 388 (Fig. 1) and with its breast T resting against the breast gage 312. Upon the release of the treadle rod 380 the spring 384 through the upright arm 368 and mechanism carried thereby, which will later be described, causes the compensating block 354 to move forwardly of the machine carrying with it the rear gage plate 308 and heel clamp actuator 346. Should the rear gage plate 308 come into contact with the heel before the clamps 332, the 'compensatitng block 354 will continue to move forwardly, the pinion 352 rolling upon the ratchet teeth 348 of the rear gage plate and urging theheel clamp actuator 346 forwardly until the heel clamps contact with the side of the heel,at which time forward movement of the compensating block ceases,the'
heel being held in position by the treadle spring 384. g Y A convenient form of locking mechanism for the heel-engaging mechanism and the b ack gage 282 is shown as embodying a device which locks the back gage 282 as well as the rear gage plate 308 and the heel clamps 332 for holding the heel firmly in the heelengaging means.
The locking mechanlsm comprises a ratchet disk 390 mounted on the frame of the machine and engaged by a depending pawl 392 mounted upon an eccentric sleeve 394 carried by the pawl pin 372 and provided with a pawl spring 396 fastened in the yoke 370 for urging the pawl into engagement with the ratchet disk 390. The eccentric sleeve 394 has a laterally (Fig. 10) duringthe trimming operation of the machine.
: The lever .378 which is free to rock on the shaft364 and carries projecting lugs 376;
arranged to engage the lugs 374 of the hub 366 is provided with an upstanding ear 404 which is adapted to engage a laterally extending portion406 of the pawl 392 so as to rock the pawl in'a clockwise direction to raise the pawl .392 from the ratchet disk 390 prior tothe time that the lugs 376 of the lever 378 engage the lugs 374 of the hub 366. Upon depression of the treadle rod 380 the upstanding ear 404 moves in a counterclockwise direction, as-viewed in Fig. 10, and lifts the pawl .392 from engagementwith the ratchet disk 390. Upon further depression of the treadle rod, the lugs 376 on the lever 378 engage the lugs 374 of thehub 366 and rock the upright arm .368 in'a counterclockwise direction (Fig; 10) carrying with it the rock shaft 364 which moves the compensating block354 rearwardly of the machine, thereby moving the back gage rearwardly of the machine and opening the heel-engaging device for the removal of the heel. A new heel is then inserted in the heel-engaging means and the pressure of the treadle is released allowing the spring 88ito move the lever 378 in a clockwise direction. As the lever moves in a clockwise direction, its upstanding car 404 engages the eccentric actuator 398 to throw the pawl againstthe ratchet disk 390 and to rock the upstanding arm 368 in a clockwise direction (Fig. 10). Since the upstanding arm 368 is actuated in a clockwise direction through contact of the upstanding car 404 of the lever 37 8 with the eccentric actuator 398, the pawl 392 will at all times be pressed down upon the ratchet disk to prevent backlash, the parts of the mechanism thus being held against backward movement.
In carrying out the heel-seat fitting operation the operator depresses the treadle rod 380 to open the heel-engaging means and places a covered heel in said heel-engaging means with its breast engaging the heelbreast gage 312 which has been initially ad justed. The treadle rod 380 is then released whereupon the heel clamps move inwardly from the sides of the heel and the rear gage plate 308 moves forwardly of the machine to grip the heel and lock the same in place, the back gage at the same time being automatically positioned to determine the length of the heel-seat to be trimmed.
The operator next places the inverted shoe upon the shoe-supporting plate 30 with its heel end toward the machine and slides the work support 12 rearwardly until the rear end of the shoe engages with and is stopped by the back gage 282, the shoe-supporting plate 30 being depressed by hand against the pressure of spring 36 so that the thin finger portions 130 of the crease plates 66 may enter the crease between the shoe upper and the sole. 2
The treadle 72 is then depressed causing the sliding beds 92 to be moved toward one another and the crease plates 66 further to enter the crease between the upper of the shoe and the sole. As the treadle 72 is still further depressed the post 20 is moved upwardly and as the treadle 72 comes near the bottom of its stroke the holddown clamp 112 is brought into operative position upon the heel-attaching face of the sole of the shoe (Fig. 4), the crease plates continuing to enter between the shoe upper and the sole until they are stopped by the line of stitching A. During the heel-seat fitting operation the treadle 2 is kept depressed to hold the parts in their relative positions, the sole being substantially flat with its marginal portions undistorted by the entrance of the crease plates.
lVhen the shoe has been placed in operating position the operator next depresses the hand lever 234 which allows the one-revolution clutch 232 to rotate the cam 78 a single revolution, thus actuating the beveling knives 84 and the shouldering knives 86. It is generally customary to make the beveling cuts before the shoulder cuts but the order of opera tion of the knives may be changed it desired. lVhen the pressure on the treadle 72 is released the sliding beds 92 are automatically moved away from one another and the hold-down clamp 112 is automatically raised from the sole of the shoe. Finally the work support 12 which is now unlocked is moved away from the machine to remove the shoe and the treadle rod 380 is depressed to remove the heel from the heel-engaging mechanism.
While the machine has been described as comprising the beveling knives 84 and the shoulder forming knives 86, it will be understood that the machine is designed to fit the heel-seat portions of shoes which have been previously trimmed lengthwise thereof. In order to condition the machine for operating upon a shoe the sole of which has been particularly fitted as above indicated, the knives 84 are first removed from the machine and a shoe supported upon the ack is positioned lengthwise thereof in the machine by the back gage 282 as already explained. After the shoe has been positioned in the machine the marginal portions of the heel-seat portion of the sole, which have been partially severed from the sole, are removed from the sole and heel-breast-receiving shoulders formed upon the sole by moving the shouldering knives 86 transvemely of the sole as above described.
While the hold-down clamp 112 has been described and illustrated as part of the machine, it has been found that such a clamp is not an essential element in the heel-seat trim ming operation since the crease plates may be constructed to resist the upward pressure of the post 20 and to hold the shoe in position to have its heel-seat fitted while the sole is in an undistorted condition. When using the machine without a holddown clamp, crease plates may be employed which are gradually thickened toward their rear portions 414, as shown in Fig. 13. so that they will be stout enough to stand the upward pressure called for in a machine of this nature without being thick enough to distort the sole.
It is sometimes the practice not to sew the sole of the shoe to the shoe upper rearwardly of the heel-breast line and under these conditions there is no line of stitching to limit the penetration of the crease plates between the shoe upper and the sole of the shoe; In order to fit heel-seats on shoes of this character as well as on shoes having soles which have been attached to the shoe rcarwardly of the breast line, the form of crease plates illustrated in Fig. 7 may be used. These crease plates are per and is in an undistorted condition havsubstantially the same as the crease plates above described, except that each of them is provided with a depending portion 410 (Fig.
7) which portion is adapted to conform to 5 the general lateral outline of the last 412 upon which, as illustrated in Fig. 7,the'shee is mounted, so that the penetration of the crease plates into the crease between the shoe upper and the sole is limited by the engagement of the depending portions of the crease plates against the counter portion of the shoe upper.
