Specification of Letters Patent.

Patented April 24, 1906.

Application filed October 28, 1900- Serial No. 34,011.

To all whom it may concern.-

Be it known that I, ERASTUS E. WINKLEY, a citizen of the United States, residing at Lynn, 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 followin to be a full, clear, and exact descripers skilled in the art to which it appertains to 'make and use the same. The present invention relates to sole-pressing machines including that class of machines known in the art as sole-laying machines, by which the outsole is attached to the lasted upper and insole of a shoe and made to conform to the contour of the bottom of the last preparatory to its permanent attachment by means of stitching or otherwise, and also including that class of machines known in the art as sole-leveling machines, by which the outsole after having been ermanently attached to the shoe is subjecte to pressure to give it the proper shape or curvature. The present invention relates more particularly to. sole-pressing machines of either shoe-sole is subjected to pressure between a suitably-shaped form and a jack upon which the shoe is supported.

In direct-pressure sole-pressing machines as heretofore constructed means have been provided for relatively actuating the jack and form to bring the jack into a position to allow the removal of a shoe previously acted upon and the adjustment of another shoe thereon, said osition bein a position of presentation, and or bringing the jack and form into a osition to exert ressure on the sole of a s oe supported on t e jack, said position beinga osition of pressure. In order to hold the ing the time required to press the sole of a shoe, all such machines with which I am familiar are provided with means whereby the machine is thrown out of operation when sition of pressure, in which position theyremain until the machine is again thrown into The duration of mentof theoperator, and as a consequence the soles are often not properly pressed, the formand jack being ke t in the position of pressnteao. long as to distort the sole or not ally; and to this end my invention consists in i a machine provided with a sole-pressing form and a shoe-supporting jack, of mechanism operating automatically and continuously to bring the jack and form into a position of pressure to hold them in such position during the time required to press the sole of a shoe placed on the jack and'thereafter to separate the jack and form to bring the jack into a position of clearance. I r

Direct-pressure sole-pressin machines of the prior art have been provide with two sole pressing forms and two cooperating jacks arranged to act alternately in pressing the soles of shoes supported on the jacks, the arrangementbeing such that while one jack isin a position of pressure the other jack is in a position of presentation. By this arrangement the operator is enabled to remove the shoe previously acted 'upon from one jack and long enough to cause the soleto take the de- I place another thereon while the sole of the I other shoe is being pressed, thereby effecting a considerable savlng in time. .The jacks have, however, been constantly connected to" their actuating mechanism or to each other,

so that the operator after having removed a shoe from the jack in the position of presentat'ion and placed another shoe thereon has been obliged to wait during the time required to bring said jack to its position of pressure and the other jack to its position of presentation. Moreover, as the machines are, arranged to be thrown out of operation when either jack reaches its position of pressure and are only thrown into operation by an act of the operator, the speed 'at which the machines work is dependent entirely on the will of the operator.

Another object of my invention is to provide a' machine of the type referred to in which the jacks and forms shall be so actuated that at no time duringthe operationof the machine will the operator be required to wait for certain movements to be completed before a shoe canbe removed from or adjust-. ed'on one of the jacks,

Another object is to provide a machine of the type referred to in whichthe jacks and forms shall "be so actuated that the operator will be' obliged to keep pace with the machine;

in placing the. shoes on the jacks and remov- Iio trated in the accompanying drawings, in

which Figure 1 is a view in front elevation of'a sole-pressing machine embodying the same. Fig. 2 is a view in side elevation of the machine shown in Fig. 1.- Fig. 3 is a view of said machine in rear, elevation, a portion of the frame being broken away to show one of the sole-pressing forms in section. Fig. 4 is a longitudinal sectional view ofsaid machine on the line 4 4 of Fig. '1. Fig. 5 is a crosssectional view on the line 5 5, Fig. 1, of the machine-frame. Fig. 6 is a detail sectional view on the line 6 6 of Fig. 1, showing one of the sole-pressing forms and one of the locking-cams and Fig. 7 is a plan view of the table upon which the jacks are supported.

The machine illustrated in the drawings is similar in many respects to the sole-pressing machine disclosed in my Patent No. 627,034, dated June 13, 1899; but it is to be under stood that I have shown. my invention as applied to such I machine for convenience of illustration only and that the invention might be applied to other machines and em bodied in many different constructions.

Referring to the drawings, in which like characters of reference indicate like parts, 1 indicates the frame of the machine, having journaled in the rear lower portion thereof a driving-shaft. 2, provided with a loose driving-pulley 3 and a worm 4. The worm 4 meshes with a worm-gear 5, secured to a horizontal shaft 6, journale-il in the machineframe at right angles to the driving-shaft 2.

Securei to the shaft 6 is a worm 7, meshing with a large worm-gear 8, fast on a shaft 9, ournaled in the machine-frame and having secured thereto the cams from which the opcrating parts of the machine are actuated, as

will be hereinafter described.

11 designates the shoe-supporting jacks adapted to receive and hold suitable lasts 12,

' and 13 designates the sole-pressing forms.

In the drawings two sole-pressing forms and two cooperating jacks are shown; but it will be understood that any desired-number of forms and jacks might be employed. The jack maybe of any convenient or common form suitable for holding a wooden or iron last or any suitable device for supporting a shoe after removal from-the wooden last. The form'may be of any suitable construe tion adapted to exert pressure upon the sole of a shoe supported on the jack and may be the rigid metallic form commonly used. in

sole-leveling machines or the flexible pressing-padused in sole-laying machines. Ae-.

sentation. Any suitable mechanism for so actuating the jacks and forms may be provided. In the machine shown in the drawings a jack is moved horizontally from its position of presentation to a position directly beneath one of the sole-pressing forms, said position being a position of clearance. Thereafter the form is lowered in contact with the sole ofthe shoe supported on the jack, in

which position it is locked. The jack is then the jack is returned to its position of presenfor raising and lowering the jack are substantially the same as the mechanisms for eflecting these movements in the machine of the patent hereinbefore referred to ,but inasmuch as these mechanisms are fully illustrated in the drawings forming apart of this:

application they will be briefly described herein. As shown in the drawings, each form 13 consists of a block provided with a metallic faceplate 14 cf the desired shape or curvature and with a dovetail projection adapted to be received in suitable guidewa s 15 of a block 16 and to slide therein. T e longitudinal position of the form with relation to the block 16 can be adjusted by means of an adjusting-screwli, having a screwthreaded engagement with an upwardly-extending portion of the form and bearing against the end of the block 16. The form is locked in adjusted position by means of an arm or pawl 18, pivoted to the block 16 and arranged to swing downwardly over the end of the screw 17. The upper edges of the block 16 are provided with lateral arcshaped flanges which engage suitable gu1deways of a cross-head 19, arranged to re c1procate vertically in suitable guideways 1n the upper portion of the machine-frame. By means of the connection above described between the block 16 and the cross-head 19 the pressing-form can rock, so as to conform to the shape of the last. The form s normally heldin a horizontal position by means of coiled springs 20, connecting the block 16 with the cross-head 19 To the cross-head 19 is secured a vertical rod 21, the lower end of which projects through a bearing 22 on the machine-frame and through which it is free to reciprocate. To the rod, 21 is secured a rack 23, with which meshes a segmental gear 24, carried upon one arm ofthe bell-crank lever 25, pivoted at 26 on the machine-frame, and the other arm of which carries a roll arranged to be engaged by a peripheral cam 27, secured to the shaft 9.- The shape of the cam 27 is-such that the cross-head 19 is almachine.

lowed to descend of its. own weight at the proper time to bring the form 13 into contact with the-sole of the shoe supported on the jack which is beneath the form and thereaf ter is raised through the bell-crank-lever 25,

gear 24, rack 23, and rod 21.

For locking the forms 13 to withstand the upward pressure of the jacks a shaft 28 is mounted in suitable bearings in the machinefi'ame above the cross-head 19, and upon said shaft are secured cams 29, Also secured to the shaft 28 is a segmental gear 30, which meshes with a segmental rack 31, carried by the swinging. lever 32, fulcrumed at 33 on the machine-frame the lower end of said lever being provide 'with a cam-roll arranged to be engaged by a peripheral cam .34, secured to theshaft 9. Around the shaft 28 is.arranged a coiled spring 35, one end of which is secured to acollar fast on the shaft and the other end of which engages the macnineframe, the arrangement of the spring being such thatthe spring tends to rotate the shaft to turn the cams 29-toward the front of the theywill c'ontact with-the cross-head 19 and .lock'the cross-head and form against upward movement.

\ v v The shape of the cam 34 is such that throu gh the connections above described the shaft 28'will be rotated at the proper time to'turnthe earns 29 backward torelease' the cross-Head 19 and allow it .to beraised, as hereinbefore described. It will be noted that'thereleasing movement of earns 29 is positive, while then looking movement is spring-controlled, so that the locking movement automatically varies inextent to provide for diflerent elevations of the crosshead 19, causedby differences in the height of the last or thickness in the sole of the shoe upon-which the form rests.

The j acks 11 are carriedby a table 36, free to reciprocate vertically along suitable guideways 37, and for raising and lowering the table to bring thejacks into a position of pressure the following mechanism is provided: Upon the lower side of the table is fulcrumed the upper member of a toggle-lever 38, the lower member of which is fulcrumed upon a vertically-movable cross-head 39, which is also movable along the Whe11'the-cams are so turned,

guides 37. To the free to reciprocate, being guided and held in position thereby. Between the .cross-head 42 and the cross-,head 39 is interposed a coiled spring 43 ,I the lower end of which bears against the cross-head 42 and the upper end againsta disk 44, upon which bears a bolt 45, having a threaded bearing in the cross-head 39. The rods 40 are capped below the guides or bearings 41 to prevent them from being drawn .out when the cross-head 39 is raised. The above-described construction is such that by raising or; lowering the bolt 45 the initial compressionof the spring 43 can be regulated-that is, the-spring can be adjusted to exert more or less force tending to hold the cross-heads 39 and 42 separated. a The crosshead 42 when the jacks are in the position of pressure is arranged to bear upon an adjustable rest or stop 46, which; as shown, consists of a suitable bolt passing through a nut 47, resting on the lower cross-bar of the machineframe. Stops 48, secured in the guideway 37 are provlded, which limit the downward movement of the table 36. When the table 36 restsupon the stops 48 and the toggle 38 is straightened, the cross-head 39 will be moved downward until. the cross-head 42 contacts with the stop or rest 46, when the resistance of the spring 43' will o'pposefur- "ther downward movement of the crosshead 39, and the table 36 will therefore be raised, and if one of the jacks has been brought beneath one of the forms the jack and form will be brought into a position of pressure.

provided pivoted at one end to the joint ofthe toggle-lever and at its other end provided with a fork straddling the shaft 9 and with a cam-roll engaging the groove of a cam 50,secured to the shaft 9.

The jacks 11, as shown, consistofblocks' arranged to slide in suitable guideways 51, secured to the table 36, each jack" being provided with suitable holes or openings-52 for receiving pins projecting downward from the lasts 12. chine shown in the drawings is provided with an actuating mechanism common to all the jacks, and means are 'provided whereby either or all of the jacks can be connected and disconnected from the actuatingmechanism. This jack actuating mechanism is constructed as follows: Pivotally mounted on a horizontal rock-shaft 53 at the rear lower portion of the machine-frameare two upwardly-extending levers 54, rigidly con-' nected at their lower ends by --means of a For actuatingthe jacks the ma- 1'15 For operating the toggle-lever 38 alink 49 is sleeve, as shown in Fig. 3, and connected at their upperends by means of-a rock-shaft'55, journ'a ed therein. The right-hand lever'54, as viewed in Fig. 3, is provided with a camroll engaging the groove of a cam 56, secured c the driving-shaft 2 to the shaft 9, whereby the levers 54 are swung backward and forward upon their pivot 53 during the rotation of the shaft 9. Pivotally mounted on the rack-shaft 55 or on the levers 54 are forw.filly-extending links 57 having pivoted at their forward ends hooked pawls or latches 58, arranged to engage projecting lugs 59 on the jacks 11. For guiding the links 57 during the backward and forward movements a slotted bracket 60 is secured to each side of the table 36, a headed in proj ecting laterally from the forward end of each link engaging the slot in the bracket. Pivoted to the table 36 in line with the ath of movement of the latches 58 are han -levers 61, the inner .ends of which are provided with inclined portions 62, which when the levers are swung into a position to bring such portions into the path of movement of the latches engage the inclined forward ends of the latches and raise them out of engagement with the projections 59 of the acks. By this construction it will be seen that both jacks can be connected to their actuating mechanism, so as to be moved simultaneously, or either one of the jacks so connected, the other jack remaining disconnected. It will also be seen that each ack will be automatically disconnected i'rom its actuating mechanism when brou ht into its position of presentation if'the hand-levers 61 are placed in the proper position. When the jacks are 0 erated simultaneously, it is desirable that t e operation of the machine be stopped when t e jacks are returned from the position of pressure to the position of presentation in order to give the operator time in which to remove the shoes from the jacks and place other shoes thereon, and when the jacks are operated alternately it is desirable to stop t 1e operationof the machine when either of the jacks is returned from its position of pressure to its position of presentation if the operator has not had time in which to remove the shoe previously acted upon from the other jack and to replace it by another. A convenient means for so stoppin the operation of the machine is shown in the drawings and will now be described.

The loose drivingulley 3 is clutched to uring the operation of the machine by a clutchinember 63, splined on the shaft and forced into contact with the hub ofthe loose pulley by a coiled. spring 630. The clutch member 63is provided with an inclined projection 64, (see Figs. 1 and 3,) which is arranged to contact with an arm 65, secured to the rock-shaft 53, and force the clutch member out of engagement with-the pulley when the arm is-brought into the path of the projection. lhe rocl-:-shaft 53 has secured thereto a laterally-projecting arm 650, (see Fig. 2,) which isconnectc d, by means of a rod 66, to an arm 67, *securedto the rock-shaft 55. Also secured to the rock-shaft 55 are two arms 68, and from each arm 68 a rod 69 extends through a lug 70 on the upper side of a link 57 and through the upturne end 71 of a latch 58. The forward end of each rod 69. is headed, as at 72, and a coiled spring 73, surrounding the rod, is interposed between the lug 70 and the upturned end 71 of the latchQ Surrounding the rod 66 is a coiled spring 74, the upper end of the spring bearing against a lug on one of the levers 54 and the lower end of the spring bearing against the collar 75, adjustably secured to the rod. Each spring 73 is stronger than the spring 74, so that when either spring 73 is allowed to act on a rod 69 the rod 66 will be raised against the tension of spring 74 and through the arm 650 and rock-shaft 53 move the arm away from the path of the. rojection 64 of the clutch member 63. 58 are raised into the position shown in Fi 2 by the inclined portions 62 of the han levers 61, the upwardly-pro iecting portions 71 of the latches will compress the-s rings 73 and at the same time move away om the heads 72, thereby freeing the rods 69 from the pressure of the springs 73 and allowing the spring 74. to depress the rod 66 and bring en, however, both latches the arm 65 into the path of the lug 64. By.

the above-described arrangement it will be seen that the jacks are automatically disconnected from their actuating mechanism when brought into the position of presentation from a osition of pressure and that simultaneous y the machine is thrown out of operation. .It will also be seen that when one of the hand-levers 61 is moved to allow a latch 58 to engage the rojection 59 of a jack, and thereby connect t e jack with its actuating mechanism, the machine is simultaneously thrown into operation.-

In the practical operation of the machine it is int nded that the jacks be actuated alternately, a shoe previously acted upon being removed from one jack and another shoe placed thereon while the other jack is being brought into a position of pressure and returned to its position of presentation. The

normal position of the hand-levers 61 will be with their inclined portions 62 in the path of movement of the latches 58-. By keeping the hand-levers in this position the machine will be automatically stopped as each jack is returned to its position of presentation. The actuatin -cams are so constructedand timed that when a jack has been connected to its actuating mechanism and the machine thrown into operation by a movement of a lever 61 the jack and its 006 eratin form will be actuated to bring the ack and form into a position of pressure to hold them in such position during the time requiredto press the sole of the shoe laced on the jack and thereafter to return the jack to itsposition of presentation. By so, actaatingthe jack and form the duration of the pressure is controlled entirely by the machine, and the sole of the shoe is properly pressed. During the operation of the machine in pressing the sole of a shoe placed upon one of the jacks and returning the jack to its position ofpresentation the'operator can remove the shoe previously acted upon from the other jack and place another shoe thereon, and immediately the first-mentioned jack returns to its position of presentationea'n connect the jack upon which the shoehas been placed with its actuating mechanism and proceed to remove the shoe from the first-mentioned jack without waiting for any movements of themachine to be completed," The entire time of the operator can thus be employed in the removal from and adjustment of the shoes on the jacks. The machine should be so speeded that the time required for completin the pressing of the sole of a shoe place upon one of the jacks and returning the jack to its position of presentation is that required by the operator in removing a shoe from the other jack and placing another shoe thereon. The operator is thus obliged to keep pace with the machine, as otherwise the machine will come to rest for an unreasonable length of time with both jacks in the position of presentation, and thus call attention to the fact that the operator is not keeping.

pace with the machine.

It is believed that the operation of themachine above described has been sufficiently indicated to be readily understood, and furt'her description thereof is deemed unnecessary.
