SOLE-PRESSING MACHINE.
Application filed November 4, 1919. Serial No. 335,624.
To all whom it may concern:
Be it known that I, HARRY D. ELLIOTT, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Sole-Pressing Machines; and I do hereby declare the following 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 sole pressing machines. and more particularly to the type of sole pressing machines which are known in the art as sole laying machines.
In sole laying machines as now commonly constructed a relative movement of approach is imparted to the shoe supporting ack and the sole pressing pad, by means of a treadle actuated mechanism, to cause the sole to be engaged between the shoe and pad, and thereafter a relative sole pressing movement is imparted to the jack and pad by power actuated mechanism thrown into operation by the operator. One advantage of a machine of this construction is that a predetermined pressure may be applied on the sole irrespective of the thickness thereof or the height of the shoe, or, in another aspect of the matter, that the pressure action of the machine is regulated or controlled by the thickness of the work. mechanism of these machines, however, puts considerable work on the operator and also renders the machines somewhat slow in operation. 1
An object of the present invention is to produce a novel and improved sole laying machine which in addition to having the advantage above described of said prior machines, is provided with power operated mechanism for in'iparting to the jack and pad both relative movements of approach and sole pressing movements. I I *i lVith this and other objects in view, the features of the invention comprise certain constructions, arrangements and combinations of parts hereinafter described and claimed, the advantages of which will be obvious to those skilled in the art.
The several features of the invention will be clearly understood from the following description and accompanying drawings in which:

The present invention is illustrated in the drawings as embodied in a machine ar-. ranged with twin presses to lay the soles on right and left shoes respectively, the sole being laid on one shoe by one press while the work is being changed on the other press. Each press comprises a sole laying pad 2 and a shoe supporting jack 4 positioned beneath the sole laying pad. In the operation of the machine a jack is raised by power operated means to position the sole of a shoe placed on the jack in light contact with the associated sole pressing pad and then the jack is raised a predetermined distance to apply pressure to the sole. The operation of the machine in this manner. results in a "predetermined pressure being applied on the sole irrespective of the thick,- ness thereof or the height of the shoe, \Vhen one jack is being thus raised to lay the sole, the other jack is being retracted from its pad and at the completion of'the retracting movement, the jack is automatically tilted forwardly and the machine is automatically brought to rest. The forward positioning of the jack upon. stopping the machine permits the work to be readily and conveniently changed. When it is desired to again start the machine into operation, the operator returns the retracted ack to its operative position beneath the pad which automatically throws into operation the 'inechanism for raising the retracted jack as described and for retracting the other jack'to repeat the cycle of operations.
The sole laying pads are held against the pressure of the jacks by means 'ofithrust (ill springs and there: is provision in the machine for independently adjusting these springs which thereby varies the amount of pressure applied on the soles. There is alsov provislon in the machine for adjustmentof .the pads simultaneously toward and from the jacks.
Each sole pressing pad is mounted on the under side of a carrier 6 which in turn is pivotally mounted in a yoke formed'at' the lower end of a vertical slide 8, the upper end of which slide is cylindrical and is guided by a bearing 10 in a cross-head 12 hereinafter described. The upper portion of the slide 8 is provided with an axial aperture 14 the lower end of Which-is reduced to -form annular shoulder 16. The Slide is held-1n the bearing 10 by means of a bolt 18 which extends through the axial aperture 14 and the lower end of which is provided with a collar or head 20 which engages the under side of the annular shoulder 16' The upper end of the bolt 18 extends through central from which engages vertical-slots 29 in the slide 8 and the bearing 10. The pad is urged downwardly to resist the a pressure of the j 'ack by means of a spring 30 coiled about the bolt 18 and interposed between the annular shoulder 16 and the nut 26. By adjusting the tension of this spring through the hand wheel, the pressure applied on the work by means of thepad and jack may be varied and this adjustment. may be readily effected by means of the hand wheel 24. x The crosshead 12 upon which both pads are mounted is supported at its ends by vertical standards or rods 82 which extend through apertures in the ends oi the cross-head and the crosshead is clamped at itsends tothe standards by means of suitable clamping devices; 34. The cross-head is centrally supported bymeans of a vertical rod 36, the lower end of which is secured to the frame of the machine and the upper end of which is threaded through a sleeve 38 which in turn journaled ina. vertical bearing 39 inthe crosshead. The sleeve 38 is held from longitudinal movement in its bearing by means of a collar 40 secured to its upper end and by a hand wheel 42 secured to its lower end-engaging the ends of the bearing 39. l/Vith this construction, the sole pressing pads may be adjusted toward and from the jacks byfirst releasing the clamping devices 34 and then turning the hand wheel 42. I
Each shoe supporting jack is mou'nted'on a carrier 46 which in turn is mounted to slide the pad is imparted from a driving member of the machine throughyielding connections with the carrier. At thecompletion otthi s movement, the jack is held in position to retain the sole in contact with the pad by means of a locking device comprising a pawl and ratchet which locks the carrier to the cross-head. The sole pressing movementis also automatic and is imparted to the jack by mechanism comprising a toggle connected to the cross-head and actuated by the main:
driving shaft of the machine.
The mechanism for impartingthe initial movement to the jack comprises a pair oi cam segments 66 located beneath the carrier which, when swung upwardly, act to raise the carrierby engagement with apair of rolls 62 loosely mounted on a horizontal shaft 64 secured to the carrier. The shaft 64 extends through transverse apertures in" the bearing 58 and through a slot 66 iirthe guiding stud 56, the slot 66 being elongated in order that the shaft 64. may not interfere with themovement of the carrier on the cross head. The locking device for locking the carrier to the cross-head at the com pletion or the initial movement of the ack comprises ratchet member v68 secured to:
one side of the outer one of the cani seg ments 60, which ratchet member is engaged by a: spring pressed pawl 70 pivoted at 72 on the cross-head. The cam segments 60 are secured to a hori ioiital shaft 74' which extends through an aperture in the stud 56 and has its ends journaled in hearings in the cross-head. The shaft 74 is rocked to swing the cam segments 60 upwardly by means of an arm 76 which forms an extension of one of the cam segments. The ar ni I6 is swung upwardly to thus actuate the cam segments by mechanism actuated by an oscillating shaft 78 journaled in bearings in the base of the machine. The shaft 7 8 is continuously oscillated means of.a cam 80 formed, on the hub of a driving pulley 82 loosely mounted upon the driving' of a spring 93 acting on a horizontal arm 94 of the lever 88. The connections between the rock shaft 7 8 and the cam segment actuating arm 76 comprise a rod 96 having its upper end pivotally connected to the arm 76 and its lower end extending through a sliding sleeve 98 pivotally mounted on the outer end of an arm 100 which is loosely mounted on the rock shaft 78. Means are provided so that when it is desired to impart the initial movement to the jack, the arm 100 will be connected to the rock shaft 7 8 in such manner that upon movement of the rock shaft in a counter-clockwise direction, Fig. 8, the arm 100 will be swung upwardly therewith which, through the sliding sleeve 98 and a spring 102 coiled about the rod 96 will yieldingly raise the arm 76, he spring 102 being interposed between a collar 104 secured to the rod 96 and a collar 106 loosely mounted to slide on the rod and adapted to be engaged by the sleeve 98. The means for thus connecting the arm 100 to the rock shaft 78 comprises a pawl 108 pivoted on the arm 100 and acted upon by a leaf spring 110 which engages a tail piece 112 projecting from the upper end of the pawl. The lower end of the pawl is normally maintained out of engagement with the rock shaft 78 against the action of the spring 110 by the engagement of the tail piece 112 with the rear end of a lever 114 pivoted at 116 on the base of the machine. At the proper time the lever 114 is disengaged from the tail piece of the pawl, allowing the end of the pawl to be swung against the rock shaft 78, so that upon the next movement of the rock shaft in a counter-clockwise direction, (Fig. 8), a
notch 118 therein will engage the end of the pawl and carry the arm 100 upwardly there with. Upon the return movement of the rock shaft the pawl 108 is disengaged therefrom by the engagement of the tail piece of the pawl with the end of the lever 114 which has previously been returned into the path of the tail piece as presently described. The arm 100, during this return movement of the rock shaft, is returned to its initial position against a stop screw 120 on the frame of the machine by a spring 122 connected with the free end of the arm. This return movement of the arm 100 carries the sliding sleeve 98 therewith, but the rod 96 scribed, the lever 114 is swung out of engagement with the tail piece of the pawl. 108 and when the rod is released by vertical movement of the jaclgwvhich occurs prior to said return movement of the rock shaft 78, a spring 126 connected with the rodactsthrough the rod to return the lever intothe path. of the tail piece of the pawl, this return movement of the lever being limited by the engagement of a stop screw 12'? on the end of an arm thereof with the machine frame.
It will be understood that while the a mechanism connecting only one jack with which engage the rods 32. The mechanism for actuating each cross-head is automatically thrown into operation at the completion of the initial movement of the associated jack, and after the cross-head has been raised a predetermined amount, this mechanism is thrown out of operation and the cross-head is held in sole pressing position. This mechanism comprises a toggle 128, the upper end of the upper arm of which is pivotally connected to the crosshead and the lower end of the lower arm is pivotally connected to the frame of the machine. The knee of the toggle is connected by a link 130 with a wrist pin 132 carried by a gear 134, the wrist pin and gear constituting a crank for actuating the toggle. The gear 134 is carried by a shaft 136 journaled in a hearing at the base of the machine, which shaft is driven by the driving shaft 84 of the machine through a pinion 138 carried by the driving shaft, which meshes with the ,gear 134. Means is pro vided for connecting the driving shaft 84 with its driving pulley 82 so thatat the completion of the initial movement of the jack, the driving shaft will act to drive the shaft 136 180 degrees which will straighten the toggle 128 and thereby raise the cross head the requisite amount. The driving shaft will then be automatically disconnected from its driving pulley so that the jack will remain in its sole pressing position.
The means for thus connecting the driving shaft to the driving pulley comprises-a clutch shifting collar 140 which is splined on a sleeve 142 secured to the driving shaft. Upon shifting the clutch collar 140. rearwardly, clutch members 144 and 146 carried by the sleeve 142 are brought into engagement with friction clutch surfaces 148 and 150 on the hub of the driving pulley. The clutch member 144 is loosely mounted on the sleeve 142 and is connected with the clutch collar 140 by a pair of arms 152 projecting rearwardly from the clutch collar, the ends of which arms are turned inwardly to engage a groove 154 in the clutch member 144. The rearward movement of the clutch collar 140 acts through the arms 152 to bring an internal friction clutch surface on the rear end of the clutch member 144 into engagement with the friction clutch surface 148 on the hub of the driving pulley, whereupon the clutch member 144 is rotated with the driving pulley. The other clutch member 146 carried by the sleeve 142 comprises an expansion clutch ring 156. At the start of the rotation of the clutch member 144, the clutch ring 156 is expanded and firmly clutches the driving shaft to the driving pulley. The means for expanding the clutch ring 156 comprises a lever 158 pivoted at 160 on one end of the clutch ring and having its lower end received by a slot 162 in the clutch member 144. WVhen the clutch member 144 is rotated by engagement with the friction clutch surface 148 on the driving pulley, the lower end of the lever 158 is swung to the left (viewing Fig. 10) which causes a cam lug 164 formed on the upper end of the lever to act on the other end of the clutch ring and thereby expand the ring. The clutch ring is mounted upon lugs 168 projecting rearwardly from a flange or spider 170 forming a part of the sleeve 142. The rotation of the clutch member 144 on the sleeve 142 is limited by the engagement of a pin 172 on the clutch member with a slot 174 in the rear end of the clutch sleeve. Upon shifting the clutch collar 140 forward, the clutch member 144 is thereby carried out of engagement with the clutch surface on the driving pulley which, as the clutch member 144 is then free to turn on the sleeve 142, allows a spring 17 6 having one end connected to the clutch ring lever 158 to swing the lever in the direction to release the cam lug 164 thereon from engagement with the end of the clutch ring 156, thereby operatively disengaging the clutch ring from the clutch member 150. The driving shaft is then immediately brought to rest by the engagement of a friction brake surface 178 on the forward end of the clutch member 140 with a corresponding brake surface 180 on the frame fulcrumed on a vertical pin 186 mounted in brackets on the frame of the machine. The lever 184 is urged 111 the direction to cause the clutch members to become engaged by means of a coiled spring 188 connected with the lever, and the lever is held in position to maintain the clutch members out of engagement by means of a downwardly spring pressed lock bolt 190, the lower end of which engages the rear side of a pin 191 projecting from the upper arm of the yoke 182.
At the completion of the initial movement of the jack, the lock bolt 190 is released from the pin 191 to permit the clutch members to become engaged by the action of the spring 188. The lock bolt 190 is released at this time by the upward movement of the arm 100 mounted on the shaft- 7 8 which, as previously described, acts to initially raise the jack. The hub of the arm 100 carries a cam lug 192 which, as the arm approaches the limit of its upward movement, engages a roll 194 mounted on the free end of an arm 196 secured to a rock shaft 198 mounted in the base of the machine. An arm 200 is secured to one end of the rock shaft 198, the free end of which engages the underside of the head of the lock bolt. The engagement of the cam lug 192 with the roll 194 acts through the arms 196 and 200 to raise the lock bolt 190 out of engagement with the pin 191. hen the driving shaft is rotated the requisite amount to straighten the toggle that actuates the cross-head, the lock bolt 190 which has been released by the cam lug 192 during the downward return movement of the arm 100 is moved back of the pin 191 and then carried forwardly by means presently described which, through the yoke 182 shifts the clutch members out of engagement and brings the driving shaft to rest. The lock bolt 190 is actuated in this manner by means of a cam lever 202 upon which it is mounted, which lever is fulcrumed on the vertical pin 186. The lever 202 is actuated by a cam surface on the forward face of a cam disk 206 carried by the rear end of the toggle actuating shaft 136, a cam roll 204 on the lever being maintained in engagement with the cam surface by means of a coiled spring 208 connected with the lever 202.
hen one ack has been brought to a position ofpressure and the mach'ne is stopped as above described, the other cross-head has been brought into its retracted position as indicated in Fig. 1. As clearly shown in Fig. 1, the toggles are so arranged relatively to their actuating crank that as one is straightened, the other is broken which causes the cross-head connected with the toggle which is being broken to be retracted. As this cross-head approaches the limit of its retracting movement, the pawl of the locking device is lifted out of engagement with the ratchet member 68, allowing the cam segments 60 to swing rearwardly by gravity which in turn allows the carrier and jack to drop to their initial. position on the cross-head. The pawl is thus released from the ratchet member 68 by a lug 210 on the pawl being brought into engagement with the upper end of a releasing lever 211 pivoted at its lower end on a bracket secured to the machine frame. The upper end of the releasing lever 211 is maintained in position by means of a stop screw 212 secured to a lug on the lower end of the lever, which screw 18 held against the base of the bracket upon which the lever is mounted, by means of a spring 213 engaging an arm 214 on the lower end of the lever.
This descent of the jack and carrier is accomplished without undue jar by the provision of a buffer comprising a coiled spring 209 mounted in a socket in the guiding stud 56 on the cross-head, against which spring the shaft 64 of the carrier strikes.
The jack carrier is so constructed that as it reaches the limit of its retracting movement on the cross-head, the ack is caused to be tilted forwardly to permit the work to be changed, and accordingly the upper portion of the jack carrier is pivotally mounted and is free to swing forwardly at this time. To this end the upper portion of the carrier is provided with downwardly extending supporting arms 215, the lower ends of which are fulcrumed upon the ends of the stationary shaft or rod 64 secured to the lower portion of the carrier. During the movement of approach and the retracting movement of the carrier on the cross-head, the jack and the pivoted portion of the carrier are guided in upright position beneath the pad by the engagement of vertical guide bars 216 on the upper ends of the crosshead with slots 218 in the ends of the horizontal bar 46 secured to the top of the carrier. In order that the guide bars 216 and the ends of the horizontal bar 54 may not prevent the carrier from being tilted forwardly at the completion of its retracting movement on the cross-head, the upper sides of the rear walls of the slots in the bar 54 are cut away (Fig. 7) to permit the bar 54 to clear the lower ends of the guide'bars 216 at the limit of the retracting movement of the carrier, allowing the upper portion of the carrier and jack to be tilted forwardly by gravity. This forward movement of the jack is limited by the engagement of the upper portion of the carrier with a stop 220 projecting from thelower portion of the carrier.
In order that the pawl 70 of the locking device for the carrier will be free to engage with the ratchet member 68 during the initial movementof the jack, means is provided for disengaging the pawl from the releasing lever 211 when the jack is tilted forward.
To this end the outer supporting arm 215 of the carrier is provided with a lug 221 projecting down below the pivot shaft 64, which when the jack is tilted forward engages the upper end of the releasing lever and moves it from beneath the lug on the pawl.
The machine is at rest when the jack is thrown out as described, and it is necessary for the jack to be swung back by the operator beneath the sole pressing pad before the machine can again be thrown into operation.
When the jack is returned to operative position beneath the pad, it is automatically locked in place by means of a latch compris ing a lug 222, centrally secured to the rear side of the pivoted portion of the carrier, which is engaged by a shoulder formed on the end of an'upwardly spring pressed plunger 224 mounted in the upper end of the guiding post or stud 56 secured to the cross head, inclined surfaces 226 being provided 011 the ends of the lugsand plunger which cooperate, as the jack is brought into operative position, to depress the plunger and thereby permit its end to snap in front of the lug. The engaging portions of the members of the latch are of suflicient length so that they will remain in engagement during the initial movement of the jack carrier on the cross-head until the ends of the horizontal bar 46 on the top of the carrier are effectively brought into engagement with the guide bars 216 on the cross-head. In order that the members of the latch 222224 will not engage during the retracting movement of the jack and thereby prevent the jack from being tilted forward at the limit of this movement, a sufficient play is provided between the ends of the guide bars 216 and the slots in the end of the bar 54 so that the jack will start to tilt forward by gravity before the members of the latch will have an opportunity to effectively engage, with the result that the lug 222 will ride over the inclined surface 226 on the end of the plunger. This play between the lower ends of the guide bars 216 and the slots in the ends of the bar 54 is provided for by chamfering off the lower ends of the rear sidesof the guide bars as indicated at 227 in Figs. 7 and 7 It will be recalled that the mechanism for imparting the initial movement of approach to the jack is thrown into operation by the depression of one of the rod-s 124, a rod 124 being associated with each jack and having its upper end located to the rear of the jack carrier. In the illustrated machine the movement of the jack'into operative position is utilized to throw the actuatingmechanism for the jack into operation. -Accordingly means is provided which act to depress the starting rod 124 when the jack is lil ill
moved into operative position. This means comprises an arm 230 projecting rearwardly from the pivoted portion of the ack carrier, the end of which arm, when the jack is swung into operative position engages the upper end of the rod 12% and depresses the rod a suflicient amount to throw the actuating mechanism for the jack into operation. The rod 12a is returned by its spring 126 to its raised position as the jack rises as previously described, and in order that the end of the rod will not be engaged by the end of the arm 230 while the jack is again being retracted, means is provided for holding the jack out of the path of the arm 230 during th retraction of the jack. which means is released when the jack is tilted forward at the end of the retracting movement thereof. To this end a lug 232 is provided on the rear side of the cross-head, which as the crosshead rises cooperates with an inclined surface 23a on the rod to swing the upper end of the rod back out of the path of the arm 230 on the carrier against the action of a spring 236 having one end connected to the rod. The rod is held in this position, by means of a latch 238, until the jack retracted and tilted forward. This latch com-- prises a horizontal lever pivoted at 240 on the cross-head (Figs. 5 and 7) and provided with a shoulder 242 on the end thereof which, when the rod 12a is swung back, is snapped by its spring 24% into engagement with the front side of the rod, the shoulder riding on the side of the rod during the actuation of the cross-head. Means is provided so that when the jack is tilted forward at the end of the retracting movement thereof, the latch 238 will be disengaged from the starting rod 124 allowing the rod to be swung inwardly by its spring 286 into position to be again engaged by the arm 230 to repeat the cycle of operations when the jack is returned to operative position. To this end the inner supporting arm 215 of the pivoted portion of: the jack carrier is provided with a downwardly extending lug 248 which, when the jack is tilted forwardly, engages an aru1'250 on the latch 238 to swing the latch in a direction to release the rod.
