Definitions

  • This invention relates topulling-over machines, which are used for preparing boots or shoes for lasting by performing the operation known as pulling-over, and the invention is shown as applied to the machine illustrated in United States Letters Patent N 0. 663,777, granted December 11, 1900, and No. 950,701, granted March 1, 1910, and No. 988,582, granted April 4, 1911, and an application,.Serial No. 532,681, originally filed Jan. 31, 1903.
  • A11 important feature of this invent-ion is a heel-rest for the last, to resist backward strain upon the last.
  • This backward strain is produced mainly by the grippers, especially the toe grippers, in drawing the upper over the bot-tom of the last.
  • the wipers for wiping the upper over the edge of the last and the fastener inserting mechanisms which drive the securing tacks in a direction inclined inwardly from the edge of the last also contribute to the force tending to move the last backwardly.
  • the heelrest occupies a retracted, inoperative position when the machine is at rest
  • one feature of my invention con sists in providing means which, when the machine is started, yieldingly advances the heel-rest into operative posit-ion against the last, but preferably without materially moving the last.
  • said rest meets the heel of the last it is automatically moved laterally into position to engage properly the heel end of the last, and is then automatically locked in such lateral-position until the pullingover operation is completed, after which it is retracted and unlocked and permitted to resume its normal central position.
  • Another feature of my invention consists in providing mechanism by which the heelrest may be locked against rearward movement and also by which it may be actuated for giving the last a slight, positive forward movement after the upper has been stretched and while it is held taut by the grippers, thereby to set the shoe by forcing the last into the fore-part of the upper and causing the upper to conform to the lines of the which the heel-rest may be furtheractuated manually in case the movement automatically imparted to it 18 not sufiicient, in a particular instance, to accomplish the desired result.
  • Another important feature of my invention consists in means for positioning the inner-sole on the last. It is very desirable that the inner-sole beproperly positioned on the last with its'toe end flush with the toe end of the last.
  • the inner-sole In assembling the upper and inner-sole upon the last itis customary, particularly in the cheaper grades of shoes, for the workman to position the inner-sole loosely upon the last with the heel end against the upstanding portion of the counter or the upper at the heel of the shoe, and frequently the inner-sole is not long enough to reachquite to the toe end of the last.
  • the inner-sole may be so placed on the last that it extends too far forward and requires to be moved backwardly. I have,
  • the inner-sole is moved by means of the rest against which the shoe is held bottom upwardly during the pulling-over operation.
  • this rest hereinafter called the sole-rest will be actuated automatically for moving the inner-sole at the proper time and in the desired direction during the regular operation of the machine.
  • the sole-rest may be moved manually after the automatic movement and while the machine is at rest if, upon-inspection, the workman finds that the inner-sole has not been properly positioned. Provision is made for controlling the direction of the automatic movement of the sole-rest so as to move the inner-sole either forwardly or backwardly.
  • the rest may be manually actuated as desired for adjusting the inner-sole upon the last.
  • the mechanisms for manually moving the sole-rest and the heel-rest so that they-may be actuated by a single hand lever.
  • the mechanisms for manually operating the heel-rest and the sole-rest constitute important features of my invention.
  • these mechanisms are so constructed and arranged that the sole-rest may be moved either forwardly or backwardly at the will of the workman or that the two rests may be moved forwardly together.
  • the workman isthus enabled manually to re-arrange the asselnbled parts of the shoe by forcing the last farther forward intothe upper as the latter is held by the grippers. This may be done by the heel-rest'or, in welt work. or other high grades of work in which it is customary to tack the inner-sole to the last,
  • the last may be adjusted either backwardly or forwardly by moving the sole-rest, which in moving the inner-sole moves with it the last which is secured to the inner-sole.
  • my invention consist in the improved devices for supporting the last for the driving of the fastenings which secure the upper to the inner-sole, for wiping and pressing the pulled portions of upper over upon the inner-sole at the sides of the shoe, into position to receive said fastenings, and for holding said portions of the upper from slipping back during the interval between the opening of the grippers and the driving of the fastenings, together with the mechanisms for actuating said dewipe the upper up over the edge of the last while said upper is still held taut with the hand pincers, and then presses the pulledover.
  • wiping and pressing members preferably connected with said supporting member, and corresponding to the workman-s thumb.

PULLING-OVER MACHINE.
Specification of Letters Patent.
Patented June 11, 1912.
To all whom it may concern:
Be it known that- I, RONALD F. MoFnnnY, a citizen of the United States, residing at Beverly, in the county of Essex and Commonwealth of Massachusetts, have invented certain Improvements in Pulling-Over Ma chines, of which the following description,
in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several. figures.
This invention relates topulling-over machines, which are used for preparing boots or shoes for lasting by performing the operation known as pulling-over, and the invention is shown as applied to the machine illustrated in United States Letters Patent N 0. 663,777, granted December 11, 1900, and No. 950,701, granted March 1, 1910, and No. 988,582, granted April 4, 1911, and an application,.Serial No. 532,681, originally filed Jan. 31, 1903.
A11 important feature of this invent-ion is a heel-rest for the last, to resist backward strain upon the last. This backward strain is produced mainly by the grippers, especially the toe grippers, in drawing the upper over the bot-tom of the last. The wipers for wiping the upper over the edge of the last and the fastener inserting mechanisms which drive the securing tacks in a direction inclined inwardly from the edge of the last also contribute to the force tending to move the last backwardly. Heretofore it has been necessary for the workman to grasp the shoe at the heel with one hand and hold it against this backward strain. This called for a hand operation and taxed the strength of the workman. Moreover, it has proved to be impracticable for the workman to hold the shoe with suflicient force to prevent it from slipping back more or less as the several mechanisms forced the upper into place and secured it. These disadvantages have been obviated by the heel-rest of my present invention.
One of the problems which had to be dealt with in constructing a device of this character was due to the great variance in the shapes of lasts. To secure the best results and avoid loss of time in making adjustments, it is important thatthe heel-rest be self-adjusting to rights and lofts of various shapes of lasts, so that whatever the shape or position of the heel of the last, the heeli'cst will automatically position itself properly in the normal operation of the machine. It is also desirable that after the proper position of the heel-rest has been obtained. it be locked in such position during the pulling and sewing operations, and that it be unlocked im iediately after the completion of such operations. This locking and unlOtiiilIlg' will preferably be effected automatica y.
For securing the above-mentioned objects and overcoming the difficulties important features of this invention are concerned with the movably mounted heel rest. In the illus trated construct-ion "embodying these features the heel rest is so mounted that, while normally occupying a central position, it can move laterally to accommodate itself .to the position of the heel of the shoe that is presented to the machine. I have also provided means for locking said rest against lateral displacement during the operation of the machine, saidlocking means being made operative, after the heel-rest has been "positioned laterally, by the pressure of the shoe against the heel-rest, and being rendered inoperative when such pressure ceases.
In the embodiment of my invention herein shown the heelrest occupies a retracted, inoperative position when the machine is at rest, and one feature of my invention con sists in providing means which, when the machine is started, yieldingly advances the heel-rest into operative posit-ion against the last, but preferably without materially moving the last. As said rest meets the heel of the last it is automatically moved laterally into position to engage properly the heel end of the last, and is then automatically locked in such lateral-position until the pullingover operation is completed, after which it is retracted and unlocked and permitted to resume its normal central position.
Another feature of my invention consists in providing mechanism by which the heelrest may be locked against rearward movement and also by which it may be actuated for giving the last a slight, positive forward movement after the upper has been stretched and while it is held taut by the grippers, thereby to set the shoe by forcing the last into the fore-part of the upper and causing the upper to conform to the lines of the which the heel-rest may be furtheractuated manually in case the movement automatically imparted to it 18 not sufiicient, in a particular instance, to accomplish the desired result.
Another important feature of my invention consists in means for positioning the inner-sole on the last. It is very desirable that the inner-sole beproperly positioned on the last with its'toe end flush with the toe end of the last. In assembling the upper and inner-sole upon the last itis customary, particularly in the cheaper grades of shoes, for the workman to position the inner-sole loosely upon the last with the heel end against the upstanding portion of the counter or the upper at the heel of the shoe, and frequently the inner-sole is not long enough to reachquite to the toe end of the last. Also the inner-sole may be so placed on the last that it extends too far forward and requires to be moved backwardly. I have,
therefore, provided means for moving the inner-sole either forwardly or backwardly upon the last.
In the embodiment of my invention herein shown the inner-sole is moved by means of the rest against which the shoe is held bottom upwardly during the pulling-over operation. Preferably this rest, hereinafter called the sole-rest will be actuated automatically for moving the inner-sole at the proper time and in the desired direction during the regular operation of the machine. I have also provided means by which the sole-rest may be moved manually after the automatic movement and while the machine is at rest if, upon-inspection, the workman finds that the inner-sole has not been properly positioned. Provision is made for controlling the direction of the automatic movement of the sole-rest so as to move the inner-sole either forwardly or backwardly. Provision is also made for varying the extent of the automatic movement of the solerest and for discontinuing said movements when it is not desired to have the sole-rest automatically actuated. When the automatic movements of the sole-rest have been discontinued the rest may be manually actuated as desired for adjusting the inner-sole upon the last.
In the embodiment of my invention herein shown I have arranged the mechanisms for manually moving the sole-rest and the heel-rest so that they-may be actuated by a single hand lever. {The mechanisms for manually operating the heel-rest and the sole-rest constitute important features of my invention. In the preferred form these mechanisms are so constructed and arranged that the sole-rest may be moved either forwardly or backwardly at the will of the workman or that the two rests may be moved forwardly together. The workman isthus enabled manually to re-arrange the asselnbled parts of the shoe by forcing the last farther forward intothe upper as the latter is held by the grippers. This may be done by the heel-rest'or, in welt work. or other high grades of work in which it is customary to tack the inner-sole to the last,
the last may be adjusted either backwardly or forwardly by moving the sole-rest, which in moving the inner-sole moves with it the last which is secured to the inner-sole.
Other important features of my invention consist in the improved devices for supporting the last for the driving of the fastenings which secure the upper to the inner-sole, for wiping and pressing the pulled portions of upper over upon the inner-sole at the sides of the shoe, into position to receive said fastenings, and for holding said portions of the upper from slipping back during the interval between the opening of the grippers and the driving of the fastenings, together with the mechanisms for actuating said dewipe the upper up over the edge of the last while said upper is still held taut with the hand pincers, and then presses the pulledover. portion firmly down upon the innersole as he releases the pincers and prepares to drive the fastening tack to hold the upper to the inner-solelVith this object in view I have in the form of these last supporting and wiping and pressing devices herein shown, provided a supporting member, corresponding to the workmans hand, no
to engage the under side of the last and sustam 1t, and wiping and pressing members preferably connected with said supporting member, and corresponding to the workman-s thumb. Meansis provided for moving the said last supporting and wiping and pressing devices into engagement with the shoe, and the wiping and pressing members are preferably connected with the supporting member in such manner that they are actuated by said supporting member after thelatter comes into engagement with the shoe.
Mechanisms were 'employed in the machine of my prior Letters Patent, No.
663,777, before mentioned, for holding and inserting two fastenings, shown as tacks, at each side of the last for securing to the inner-sole the portions of upper ulled over by the grippers. These mechanisms in the machine of my present invention are arranged to insert the two tacks spaced a considerable distance apart, preferably about an inch apart, at each side of the last. It is desirable that these securing tacks be driven into the last each the same distance from its edge. Diflerent styles of lasts vary so much in shape that a tack presenting and inserting mechanism which is properly positioned for one style of last will. on a different style of last. insert one of the tacks farther from the edge than the other. To overcome this ditliculty and render the tack presenting and inserting mechanisms selfadjusting to the edges of diti'crently shaped lasts I have, in my present invention, so mounted the tack carrier block and the drivers that they may be automatically placed in proper position for inserting the two tacks at the same distance from the edge of the last or each a predetermined distance frcm the edge of the last. I have also arranged the tack inserting mechanism so as to drive the securing tacks in a direction inclined inwardly from the edge of the last, whereby the upper is pulled more closely into place by the ingoing tacks, and also the danger of splitting the last by the tacks is reduced, and the danger of driving the tack through a last having a thin edge is obviated.
These and other features of my invention, including certain details of construction and combinations of parts, will be hereinafter described and will be pointed out in the claims.
Throughout the specification and claims I have used the term shoe and sometimes the term last to designate the last with the upper, lining, counter, and inner-sole assembled thereon.

The working members of the machine are supported by a head B which is provided with a depending stem 12 vertically adjustable in a column or base A. The shoe is prepared for the machine by applying to the last the upper with its lining, the heelstifl'ener, and the toe-cap, the upper being sometimes secured to the heel end of the last by a tack, and by placing the innersole onthe bottom of the last within the upstanding marginal portion of the upper. The shoe thus assembled is presented by the workman bottom upward against a solerest, hereinafter described, with the upper The mechanism for moving the heel-rest 4 yieldingly forward as described comprises a cam block E, mounted on the main shaft '1) and provided with a cam groove 6, as shown in Figs. 1, 6, 7, and 8. A slide 10 is mounted. totravel longitudinally in a bracket 72' secured to the head B. The slide 10 is provided with a stud 8 standing in .the cam groove 6, by means ofwhich it I each complete operation of the machine.
The slide 10 is bored longitudinally to provide achamber in which isfmounted a plunger 12, see Figs. 5 and 8. The plunger is surrounded by the spring 14 which actsagainst collars 16 and 17 slidingly mounted on the plunger. -The"c'ollai' 16 is confined.
on the rear end of the plunger by a nut 19,
while the collar 17 abuts against a shoulder at the enlar ed front end ffth see Fig. 8. he collars have flanges; lfig a'nd 17 which are adapted to vengage thek'slijde 10 at the reduced end portions :10 a'nd lll" of the chamber in" said thef'slide 10 is moved to the left',jviewin Fig. 8," for actuatingv the heel-rest the 1 ort1on ;1Ol thereof acts on 'the"collar:'17, w ichin turn acts throughthe spring 14 on'the collar 16Iand the'nut 19 of the lunger to moveithe lum -,ger to the left.

The spring 14 thereby causes the movement of the plunger, to be yieldingly-eflectedin the heel-rest either direction for moving forwardly and backwardly.
The forward end of the plunger .12 is provided with rack-teeth which engage with.
a pinion 18 secured upon a shaft 20 mounted in bearings in the frame B, see Figs. 6 and 8. The shaft 20 is provided upon'its opposite ends with gears 22, 22, whichinturn engage pinions 24', 26 which-are formedas sleeves mounted loosely upona'shaft 30, 1 v see Fig. 13. The pinions 24,26 also engagerack-teeth formed upon slides 32, 34. The
slides 32, 34 have in theirlower faces undercut grooves which receive T-shaped ribs 36, 38 of a block- 40 upon which the heel-rest 4 is supported, see Figs. 7 and 10.-
The block 40 is adapted to be adjusted longitudinally of the slides 32, 34 to adapt the heel-rest for shoes'of diflerent'lengths. For the purpose of securing it in adjusted position the block is provided with spring pressed plungers 42 having on their ends pins or lugs which are adapted to be received in any one of a series of recesses 44 in the upper walls of the undercut grooves of the slides 32 34. A shaft 46 extends transversely with relation to the plungers 42 and is providedwith gear-teeth adapted to engage with rack-teeth on the plungers 42. (The shaft is provided with an operating handle 48 by means of which it may be turned. to depress the spring-pressed plungers and permit the bl0ck.40. with its attached heel-rest to be moved backwardly or. forwardly in the slides.
chambered out on itslower side toreceive two-small blocks 50, see Fig. "I, which are secured in place by pivot pins -52 that ex tend from front to rear. The blocks 50 are permitted to have free, pivotal movement on the pins 52 and are provided with transverse pivot pins 54 upon which are mounted depending arms 56. The arms 56- have The block 40 is shoulders formed on either: side of their pivot pins 54 and these shoulders serveto limit the amount of pivotal movement which (the. arms may have about said pins 54.
the shoulders back of the pins and bear against the blocks 50 in such manner as to hold the arms 56 normally swung forward. On the lower ends of the arms 56 are formed forwardly 'entending trunnions 60 which are secured in bearings formed on the rear side of the heel-rest 4. By this arrangement the heel-rest is permitted to have free, swinging,'lateral movement upon the trunnions 60 and the pivot pins 52, this movement being in a direction transverse of thelength of the shoe. The heel-rest is also permitted to have a limited rocking movement about the pivot pins 54 in a direction longitudinalof the shoe. I
The block 40 is provided with a depending portion having on its front face a corrugated or roughened surface 64. The arms '56 which carry the heel-rest support a corrugated plate or link 66 located opposite the corrugated surface 64 on the block 40 and adapted to engage said surface 64 when the heel-rest is swung backwardly about the pivot pins 54 and by such engagement to lock the heel-rest against lateral movement. The spring-pressed plungers 58 normally hold the heel-rest swung forwardly and the plate 66 out of engagement with the surface 64, as shown in Fig. 7.
The heel-rest is formed on its front side with converging faces, as shown in Fig. 11 to engage the sides of the heel end of the shoe-when the heel-rest is moved forwardlyby the mechanism above described, the recess or angle between the converging side faces receiving the usual shoe assembling tack which projects from the middle of the heel end.
It will be understood that the shoe is held by the workman against the sole-rest with the fore-part in such position as to cause the upstanding edge port-ions of the upper at the toe and sides of the shoe to stand witnin the open jaws of the grippers.
As is well known, right and left lasts vary in shapein such a way that when the forepart is positioned properly, centrally of the machine, for the grippers to engage the upper the heel of a right last will be at one side of the median line of the machine and the heel of the left last will be at the other side ofthe median line. Lasts of different styles vary in this respect in different degrees. It is necessary, therefore, to arrange the heel-rest so that it may be adjusted laterally according to the different positions occupied by the heels of different lasts. The heel-rest occupies a retracted, inoperative position when the machine is at rest and by means of the construction above described it is moved yieldingly forward from its 1noperative position until it comes into con tact with the heel end of the shoe. As said heel-rest meets the shoe, if the heel end thereof is not directly in front of the heelrest, one of the-side walls of the rest en- 'ga es one side of the heel 'wa l engages the heel, and, forward movement of theheel-rest, said'rest before the other in the continued is automatically shifted laterally by the shoe swinging on the pivot pins 52, so that when 1t comes fully into engagement with the heel 1t Will have positioneditself laterally so as to be directly in the rear of the heel end of the shoe. In the further forward movement of the heel-rest, yieldingly effected as above described, the rest isrocked rearwardly on its pivot pins 54, as shown in Fig. 8, against the action of the springpressed plungers 58, and the corrugated plate 66 is brought into engagement with the corrugated surface 64 of the block 40, so that said heel-rest is locked thereby against any lateral movement so long as said rest remains in supporting engagement with the shoe being operated upon.
The spring 14 surrounding the plunger 12, and by means of which the movement of said plunger is yieldingly effected, permits the heel-rest 4 to come to rest after bein moved into firm engagement with the shoe, but preferably without moving the last any, said spring being compressed during the re-' maining portion of the movement of the slide 10. The heel-rest is thus arranged for supporting shoes differing somewhat in length without the necessity of adjustment. For accommodating shoes varying greatly in length the heel-rest may be adjusted in the slides 32, 34.
It is desirable in most classes of work to lock the heel-rest ositively against rearward movement wliile the upper is being drawn over the bottom of the last and se-' cured to the inner-sole. It is also desirable in many classes of work to give the last a slight positive forward movement at the end of the pulling movement of the grippers in stretching the upper about the last. The purpose of this movement of the last in the pulled upper is to effect what is known in the art as the setting of the shoe, thatis the final conforming of the upper to the shape of the last.
For effecting the locking of the hee1-rest against rearward movement and the positive forward movement of the heel-rest for setting the slice, when this forward movement is required, the slide 10, before described, is provided at its forward extremity with a block 70 having at its front end an inclined face 68 adapted to engage with the rear end of a lever 72, see Figs. 6,- 7, and 8,
during the last portion of the rearward movement of the slide 10, it being understood that it is the rearward movement of' the slide 10 which advances the heel-rest and that said rest is retracted toward inoperative position during the forward movement of the slide 10. The lever 72 is pivoted at .7 n an i'ts forv a dvend' 'ProvidedfW p iii-ally in*-'engagement with aratchet wheel The ratohet 'wheeliis-formed upon or jflsecuredyto "the sleeve 'shaft' on which is {formed the pinion 24 before.

The ortion of the oscillation of the lever 72 durlng which the pawl 76 is permitted to engage the ratchet wheel 80 is determined by a pawlcontfoller 82,-shown as a hooked lug formed on a late 84 which is adjustably secured tot e head B by a bolt 86, as shown in Fig. 7 The lever 72, carrying the pawl 76, is acted upon by a springvpressed plunger 88 which normally holds that end of the lever which carries the pawl raised and the other or rear end of the lever in contact with the block. 70. While the rear end of the lever is on the plane face of the block 70 the pawl controller 82 em- .braces the upper arm 77 of the pawl 76 and holds the acting end of said pawl out of contact with the ratchet wheel 80. When said pawl away the arm 77 of the pawl has been carried 'thelever 72 is acted upon by the inclined face 68 of the block 70 to move the pawl downwardly-the Fawl controller 82 keeps rom the ratchet 80 until below said pawl controller, after which the pawl engages the ratchet and locks said ratchet against rearward movement.

The eccentric portion 94 is positioned adjacent to the-periphery of the ratchet wheel 80 and constitutes a form of pawl to engage said ratchet wheel at times. The eccentric portion 92 on the rod stands just without the outer face of the hub 90- and is acted upon by a cam face 96 of a. device 162, herein termed the pawl-disengaging device, which is pivotally connected at 165 to the hub 90 and is provided at 166 with a finger-piece by means of which it may be moved against the action ofspring-pres'sed 'plungers 168, 170 (see Fig. 9). The eccentric portion 92 of the rod 91 is acted upon by a spring-pressed plunger -98 which, when permitted to do so, turns said rod for putting the eccentric portion 94 into, engagement with the ratchet wheel 80, as shown in Fig. 17. The cam face 96 of the pawl-disenga ing device normally holds the rod 91 with its pawl 94 out of contact with the ratchet wheel 80,. but when said disengaging device is turned into the position shown in. Fig. 20 the cam face 96 is moved out of contact with the eccentric portion 92 of said rod and the spring-pressed plunger 98 is permitted to turn said. rod
about its ownjairis for moving its pawl 94 into engagement with the ratchet wheel 80. this means the hand lever 160 maybe connected with the'ratchet wheel 80 of the heel-rest actuating mechanism so that said heel-rest may be manually advanced. The
- pawl v76 acts at such times as a locking 'means to hold the ratchet 80 against rearward movement, thus securing the heel-rest .inthe position to which it may be moved.
The shoe-bottom-rest, or sole-rest, as it v is herein called, is mounted slidingly in a carrier which is pivotally supported on a the shaft 30, heretofore described,'see Figs.
3, 13, and 14. The sole-rest comprises ashank-118 having arms 124, 124 which extend obliquely forward to engage the innersole near its edge and an arm 126 which extends directly forward toward the toe of the inner-sole, see Fig. 15. The 'arm126 has an adjustable footpiece 127 pivoted to'it at 128 and acted upon by a spring-pressed plunger 130. The foot-piece is provided with a stop-screw 132 for adjusting it about its pivot to vary the vertical posit on of its 7 actin end with relation to the arm 126. By his adjustment the sole-rest may be adapted to engage properly lasts the bottom faces of which have different degrees of longitudinal curvature. The arm 126 is adjustably mounted in a channel in the shank 118 of the sole-rest. The arm is provided with ratchet-teeth which are adapted to be engaged by a spring-pressed pawl 129 mounted in one side of the shank 118, as shown in Fig. 15. The feet of the several arms of the sole-rest are roughened so as to engage the inner-sole frictionally and prevent the rest slipping with relation to it. This insures that the inner-sole shall be moved with the rest in the forward and backward movements which are imparted to said rest during the operation of the machine, as will be described.
The sole-rest is moved longitudinally of the last automatically during the regular operation of the machine and may also be moved manually when the machine is at rest.
The automatic movements of the solerest longitudinally of the last are imparted by the slide 10 heretofore described, which in turn is actuated by the stud 8 standing in the groove 6 in the cam block E. The slide 10 has a laterally and forwardly extending arm 140 (see Figs. 6 and 9), the extremity of which is formed to constitute a'split clamp 142 for holding the stud 144 of a block 146. The block is provided with a longitudinal groove 148 in which is fitted a slide-block 150. A lever 1.52 is fulcrumed on a fixed stud 154 which extends from a bracket secured to the rigid head B, see I ig. 1. Said lever has one end connected to the slide-block 150 and at its other end pivotally supports a device 156, herein called a pawl. By this arrangement when the slide 10 is moved rearwardly or to the left in Figs. 1 and 12, as it is during the first part of each operation of the machine, the lever 152 is rocked to draw the pawl 156 upwardly or to forceit downwardly, according to the adjustment of the block 146. If
the block 146 is adjusted as it is in Figs. 1 and 12, which show the respective positions of the parts at the beginning and at the end of a rearward movement of the slide 10 and block 146, the lever 152 will be rocked to draw the pawl 156 upwardly. If, however, the block 146 is adjusted as it is in Figs. 6 and 9 the lever 152 will be rocked to force the pawl downwardly. The pawl 156 is provided on its front face with an aperture or socket 158 adapted to receive a stud or lug 172 on the hub 90 of the hand lever 160 before described. A spring-pressed plunger mounted in the lever 152 bears against the pawl 156 and tends to maintain it in engagement with the hub 90. The hub is fast on the shaft 30 that has secured to it or formed integral therewith a pinion 174. which engages rack-teeth on theshank 118 of the sole-rest, (see Figs. 6, 13, and 14). It
will now be understood that when the block 146 is adjusted as'in Figs. 1 and 12 the lever 152 will operate during the movement of the slide 10 to the left to turn the shaft 30 in the direction indicated by the arrow thereon in Fig. 12 and draw the sole-rest so that its groove will be at any desired angle with the vertical, whereby to vary the extent of the forward or backward movement which will be imparted tothe sole-rest, or it can be so adjusted that the groove will occupy a horizontal position so that the lever will not be rocked at all, and the movements of the sole-rest longitudinally of the last will be discontinued. Such is the mechanism for imparting to the sole-rest its automatic movements for moving the inner sole forwardly or backwardly during the regular operations of the machine. For the purposeof enabling the workman to operate the sole-rest manually for moving the innersole forwardly or backwardly the pawl 156,
which together wit-h the stud 17 2 constitutes a locking means for normally preventing any movement of the sole-rest other than that imparted to it by the automatic mechanism, may be disconnected from the hub 90 of the hand lever 160, thus leaving said leverfree to be turned in either direction.
For disconnecting the pawl 156 from the hub 90 the pawl-disengaging device l62 has a cam 167 (Figs. 19 and 20) adapted to be moved into contact with'the pawl 156 for disengaging said pawl from the stud, 172 of the hub 90. The pawl-disengaging device is normally held in the position shown in Fig. 9 by two spring-pressed plungers 168 and 170. The spring actuating the plunger 170 is considerably stronger than the spring actuating the plunger 168 so that the disengaging device may be moved into its first position, shown in Fig. 19, by depressing the spring plunger 168 and will then come to rest against the plunger 170, unless a materially greater force is applied, whereupon the plunger 170 will yield and permit the pawl-disengaging device to be moved into its second position.
The cam face 167 is of considerable length so that when the pawl-disengaging device is depressed .into its first position the pawl 156 will be disen aged from the stud 172,: and when said isengaging device is moved farther into its second position by depressing the plunger 170, as shown in Fig.- 20,
the pawl 156 will be still held out of engage-- 'ment with the stud 17 2. The disengaging device is moved at'times into its second position, shown inFig.'-20, for carrying the cam face 96 out of the way of the eccentric portion '92 oftherod 91, and permitting the rod 91 to be actuated by its spring plunger 98 for "connecting the hand operated lever with the heel-rest actuating ratchet 80,
' as before described. Whenthe pawl-disengaging device'is in its second position the sole-rest and heel-rest are both operatively leased after the sole-rest has been operated by the lever. This insures that the stud 17 2 1 .willbe returned to position to be properly engaged by the pawl 156 at thenext operation of the machine.
As before stated, the sole-rest carrier 120 is pivotally mounted to turn about the shaft 30. The carrier 120 has an upwardly extending arm which is provided with a cam roll 368 adapted to be engaged by a face cam 37 8 on the end of the main shaft D. A spring a: is mounted in a socket in the head B and bears against the rear end of the carrier 120 to hold the roll in position to be actuated by the cam 378. The carrier is rocked forwardly by the cam against the influence of the spring, for depressing the sole-rest, and thereby depressing or sinking the last into the pulled upper. This sinking of the last into the upper takes place at approximately the end of the upward movement of the grippers for pulling the upper. Preferably the parts are so timed that the said movement of the sole rest is completed before the heel rest is advanced by the mechanism, heretofore described, far enough to interfere with the downward and backward movement of the shoe. An adjustable stop w, cooperating with a stop :2 on
. the head B, asshown in F ig. 3, controls the position of the roll 368? relative to the cam 37 8 and so determines the amount of rocking movement imparted to the sole-rest carrier.
The means for engaging and pulling the upper comprises a toe gripper mechanism and two side gripper mechanisms, one for each side of the shoe. The said gripper mechanisms are operated from ca-ms 188 nisms.
and X mounted on the main driving shaft The cam 1 88" operates through a connecting-plate 172 to actuate a lever e which is fulcrumed on a rod 152 secured in the machine head B. The lever '6 supports the toe gripper mechanism.
The connection between the plate 17 2 and the lever e isa yielding one for effecting yieldingly the upward movements of the toe gripper mechanism. To this end the conpecting plate 172 is provided witha stem 170 upon which is .slidi'ngly mounted a block 180 acted upon by a spring 176 which surrounds the upper portion of the stem 170 and the tension of which is regulated by a nut 174. The lever 63 is pivotally connected at its rear end with the block 180". This arrangement is such that when the cam 188 operates to pull down the rear end of the lever 6 this movement is yieldingly transmitted to the lever through the spring 176. The stem 170 is provided with a fixedflange 184. which constitutes a rest for the lower .side of the block 180". When the cam 188 operates for lifting the rear end of the lever 6 for depressing the grippers the movement of the grippers is positively effected through the fixed flange 1S4. Said stem 170 is adjustably connected to the connecting-plate 172 so as to allow of varying the height of the fixed flange 184: and so varying the lowermost position to which the toe grlpper mechanism will be moved. i
The toe gripper mechanism, which is pivotally supported near the front end of the lever 6", comprises a single pair of 'grippers which are preferably constructed and operated as described in said application for Letters Patent, Serial No. 532,681, originally filedfJanuary 31, 1903.
The cam X before mentioned, operates through a connecting-plate 134: to actuate two levers 154* 154 that are pivoted on the aforesaid rod 152 and which support near their front ends the two side gripper mecha- The connection between the connecting-plate 134 and the levers 15 1 is similar to the connection above described between the connecting-plate 172 and the lever e so as to effect yieldingly the downward movement of the rear end of said levers for lifting the side gripper mechanism to pull the upper. To. this end the plate 134 is provided with two stems 138-, 138, one of which is shown in side elevation in Fig. 1 and the other in Fig. 3, and each of which carries a block 1 18 acted upon by the lower end of a spring the tension of which is regulated byan'adjust-ing nut 142*. The levers 154: are pivotall connected to the blocks 148, and as said blocks are free to slide on the stems 138 the downward movement of the rear ends of the levers is effected through thesprings 150 when the cam is actuated for pulling down the connecting-plate 134*. The-stems 138 are provided with fixed flanges 147". upon which the blocks 148 rest, so that when the connecting-plate 134 is moved upwardly by the cam, the upward movement of the rear ends of the levers for moving the side grippers downwardly is positively efl'ected. The stems 'l38 'are adjustably connected to the plate 134 to permit of varying the lowermost position to which the sidegrippers may be moved. o
The levers e", and 154", 154 are extended forwardly beyond the points where the grippers are connected to constitute handles by means of which the grippers may be depressed manually, the springs 17 6 and 150* at such time yielding to permit the required movement of the levers.
The provision of independent yielding connect-ions between the gripper operatinglevers 154 and their actuating cam X not only insures that each of the side gripper mechanisms will be actuated yieldingly for grip-.
ping and pulling the upper, but also permits either one or bothof the side gripper mecha nisms to be depressed by means of the bandles of the levers 154 -for slackening the tensionon'the pulled upper. The tension of the springs 150 is so regulated that the blocks 148 will move upwardly on the stems 138 compressing the springs somewhat during the pulling operation. This insures that when either of the side gripper mechanisms is manually depressed for slackening the tension on one side of the upper, the spring 150", acting on the lever of the other gripper mechanism,- will immediately expand to take up this slack, thereby shifting theupper transversely about the last.
The side gripper mechanisms are prefer ably constructed and operated as shown and,
. described in my pending application Serial No. 200,342, filed March 28, 1904, which is a division from this application.
It will be understood that after the grip pers have pulled the upper and before they release it they are moved inwardly over the last, toward each other, to draw the pulled upper over the inner-sole in position to be fastened. This inward movement of the grippers is yieldingly effected by springsper of the" next slioe presented to theme i chine. The outward movement of the grippers to their initial positions is effected positlvely by suitably actuated spreading mechanism which is retracted automatically at the proper time in the operation ofthe machine forallowing the springs tomovethe grippers inwardl 'It is necessary to adjustthe spreading mechanism so that it will spread the grip:

mechanism so as to vary the stroke of said remains uniform in extent, but takes place between different limits.
By my improved arrangement the actuator has always a uniform stroke and imparts to the spreader a uniform stroke whatever initial position said spreader ma-y be caused to assume. p
The spreadin mechanism is not claimed in this application as it is claimed in said divisional application Serial, No. 200,342, filed March 28, 1904, but it is herein described and shown for the purpose of presenting in this application a more complete description of the machine as a whole.
The mechanism above referred tofor spreading the grippers apart after they have been moved inwardly by the springs and for holding them apart during the updraw movement of the grippers comprises a lever 802 mounted on a pin 800 in the head B, see Figs. 4 and 5. The lever has one end 816 in position to be actuated by the groove 804 in the cam block E before mentioned. The upper end of the lever 802 is provided with a toothedrack 808- which meshes with a pinion 810 on a shaft 812 mounted in the machine head B. The shaft
