PULLING-OVER MACHINE.
Specification of Letters Yatent.
Patented Nov. 4, 1913.
Application filed March 28, 1903, Serial No. 149,967. Renewed January 19, 1912. Serial No. 672,236.
To all 'whom t may concern.'
Be it known that I, RONALD F. MCFEELY, 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 Machines, 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 to pulling-over machines, which are used for preparing shoes for lasting by performing `the operation known as pullingpver the shoes.
Important features of this invention are found in the mechanism for actuating the shoe resting means', which may comprise either the shoe bottom or sole rest or the shoe end or heel rest, or both of said rests.'
One feature is found in the combination with pulling-over means, a rest for the last, as for example for the heel end of the last, and actuating mechanism for said rest, of a manually operated lever normally connected withy said actuating mechanism and means for disconnecting said lever from said mechanism. Said actuating mechanism may advantageously include a Cain and a shaft operatively connected therewith and a second shaft with means for adjustably connecting the shafts whereby the position o f the rest relatively to its driving cam can be adjusted.
Another feature of this invention consists in the combination with a sole rest, a heel rest, and manually operated means norm ally connected with the said rests for actuating them, with or without provision for disconnecting said manual actuating means from one of said rests so that the other rest may be moved alone, or with or without provision for permitting one of said rests to be moved by said manual actuating means farther than the other rest is moved.
The machine may also have means for locking one rest after it has been moved and permitting further movement of the other rest by said manual means. Preferably there is provision for returning said rests, which may have been moved through the same or different distances, always to the same initial position. In the illustrated construction, certain characteristics of which are new by this invention, a lever is normally connected with both rests for actuating them manually, the connection being made through a novel arrangement of pawls and a pawl disengaging device that is arranged to act on the pawls successively. Preferably there is means arranged to become operative after the disengaging device has disengaged one of the pawls to warn the workman that further movement will disengage another pawl. This result may be obtained for example by a plurality of springs offering a change in resistance when the successive pawls are about to be acted upon by the disengaging device.
Ano-ther feature of the invention consists in the combination with the rests and said manually operated means, of mechanisms for automatically actuating the restsy and holding them in actuated position independ ently of said manual operating means, with or without provision for disconnecting one of the rests from'the automatic means to permit of manual operation of the other rest in either direction.
These and other features of the invention including certain details of construction and combinations of parts will appear more fully fro-1n the description in connection with the drawings and will be pointed out in the claims.
Many novel features which are of my invention and are sho-wn and described in this application are claimed in United States Letters Patent No. 1,029,387, granted June 11, 1912, on an application filed concurrently with this application.
Figure l is a front elevation of a pullingover machine embodying my invention in one of the best forms now known to me. Fig. 2 is a view of the left side of the machine. Fig. 3 is a view showing the lower portion of the machine in central vertical section, other portions being shown in side elevation. Fig. 4 is a view of the heel-restand of the sole-rest, together with the mechanism for actuating said rests to move the last forward with relation to the p-ulled upper and to move the sole over the bot-tom` grippers have gripped the upper and before they have begun to pull the upper. Fig. 5 is a view showing the position of the parts illustrated in Fig. 4, after the auto-matic operation of the machine by which the grippers have pulled the upper, the last has been depressed and moved forward into the pulled upper and the sole has been moved toward the toe of the last. Fig. 6 shows the position of the parts after the sole-rest has been manually operated to move the sole farther forward to bring its edge flush with the toe of the last. Fig. 7 is a sectional view on lines 7 7 of Fig. 4. Fig. 8 is a rear end elevation of the sole-rest and heelrest operating mechanism shown in Fig. 4. Fig. 9 is a plan View of a portion of Jthe mechanism shown in Fig. 5 for moving the sole-rest and the heel-rest. Fig. 10 is a View looking to the right from the dot-ted line 10-10, Fig. 8. Fig. 11 is an enlarged View of certain parts shown in Fig. 4 in another position. Fig. 12 is a View similar to Fig. 11, showing the parts in still another position. Figs. 13 and 14 are views of a device for adjusting the heel-rest operatin-g shaft. F igs. 15 and 16 are views of the heel-rest and sole-rest operating pawls, and the adjustable devices for determining the relation of their times of engagement with their ratchet wheels. Fig. 17 is a detail side view of the heel-rest. Fig. 18 is a detail front view of the heel-rest. Fig. 19 is a sectional view on line 19-49, Fig. 17, showing the means for preventing lateral movement of the heel-rest after the last has been clamped. Figs. 20 and 21 are plan and side views, respectively, of the means for sustaining and actuating the arms which carry the mechanisms for supporting the last while fastenings are being inserted andv for wiping and pressing the pulledover portion of upper into place to receive said fastenings.
The head B of the machine is supported on a post 12X which is vertically adjustable in the column A.
D indicates the main shaft, see Fig. 3, mounted in bearings in the head and driven by a pulley 986X connected thereto by a series of speed-reducing gears X19, X20, X21, X22. The pulley is driven by a belt from a suitable driving shaft and is acted upon by a brake 982X supported on a rod 984x. Cams X30 and 18SX are carried by the driving shaft and have connection with gripper operating levers 154", 1 4X, and e.
804X indicates a groove cam having connection, by means not herein shown, with a plate 814X which is pivota-lly supported on a shaft S12x and is oscillated on said shaft by the rotation of the cam 804x. The p-late S14X is connected with the several tack driver bars 680", 682x, and 694 to lift said bars. The driver bars are depressed to insert the tacks by a spring 708X acting through a shaft 706X and an arm 718x, the free end of which rests o-n a plate 72() which bears on the upper ends of the driver bars. A slide 818x is mounted for longitudinal movement in the plate 814x, being actuated by a pinion 82.2X formed on the shaft 812x. The slide has connection (not shown) with guides 672", 674x, and 676X through which the driver bars move, and acts to swing said driver bars laterally to move their lower ends toward and from the werk. Tack carriers 640x, 600x, and 656X are carried by the guides and are moved laterally with the drivers toward and from the work. The shaft D carries an eccentric 410X surrounded by a strap which is connected through a rod 408X to a lever 404x, which has a rack and pinion connection with the shaft 398 of the tack hopper 40() for oscillating said hopper to cause the tacks y to be fed therefrom. These mechanisms are "sented tothe machine with the inner-sole against a sole-rest as shown in Fig. 4 of the drawings, and the edge portion of the upper'is inserted between the open jaws of the toe grippers and the side grippers. When the machine is started the grippers grasp the upper and pull it upwardly about the last while the heel-rest is moved into `engagement with the heel of the last, and
thereafter the shoe is held by the heel-rest, sole-rest, and grippers.
The shaft D is provided with a groove cam `6see Figs. 3, 4, 5, 8, and 21--in which is received a stud S on a block 10. The block 10 has a channel or groove in its under side in which is received the upper portion of a block 12 and alsoa spring 14 which is interposed between shoulders 16 and 18 on the end portions of the blocks 10 and 12 respectively. This arrangement is such that movement of the block 1() by the cam 6 is communicated yieldingly to the block 12 through the spring 14. The block 10 is .positively moved by the cam 6 and is connected through mechanism later to be described with the sole-rest 2 for moving the sole-rest forwardly.
Motion is communicated from the block `12 to the heel-rest 4 through the following mechanism: The block 12 is connected byA means of a rack and pinion 20, 22 with a 4vertical shaft 24. Motion is communicated from the shaft 24 through beveled gears 26,
28 to a horizontal shaft 30 which extends transversely of the machine. The shaft 30 is connected to a sleeve shaft 32 by means of a clutch, located at the end of the shaft 3G opposite to that on which the beveled gear 28 is secured. rlhe clutch comprises, see Figs. 13 and 14, a collar 34 rigidly attached to the shaft 30, and a collar 36 freely movable on the end portion of the said shaft and provided with fingers 38 which are adapted to enter alined recesses 40 formed in the collar 34 and inthe end of the loose collar shaft 32. The sleeve 36 is held normally, by a spring 42, with the fingers 38 in the recesses 40 of the fixed collar 34 and the shaft 32, thereby locking the shafts 30 and 32 together, as shown in Fig. 13 but may be moved against the tension of said spring 42 to withdraw the fingers from the notches and thereby uncouple the shafts 30 and 32, as shown in Fig. 14.
The sleeve shaft 32 is provided with pinions 44, 44-see Figs. 4, 8, and 9-for engagement with rack-teeth formed 0n bars 48, 48, which are mounted for sliding movement through the post 12 ,'as shown in Figs. 2 and 3. The bars 48, 48 vcarry the heelrest 4 on their front ends.
rfhe heel-rest is connected to the bars 48, 48 by means of collars 50 loosely mounted on the reduced ends of the bars and confined thereon by nuts 52, as shown in Figs. 4 and 5. Hangers or supports 54 for the heel-rest are connected to the Vcollars 5() by transverse pivots 56. Ilhe hangers 54 eX- tend downwardly and backwardly and at their lower ends are provided with trunnions G4 on which is mounted the heel-rest. |These connections between the heel-rest and the two bars 48, 48 permit the heel-rest to be swung laterally toward either side of the machine to adapt it to receive heels of lasts which differ in shape and to accommodate it to the lateral position which different shapes of shoes are required to assume in the machine.
A yoke G6 is connected to the bars 48, 48 in the rear of the heel-rest and is provided at G8 with a roughened surface, sce Figs. 17 and 19. A ulate 70 is supported by the heel-rest hangers 54 in positionto engage the roughened surface 68 of the yoke when the heel-rest is pressed backwardly. rlhe movement ofthe heel-rest hangers on the pivots 5G is limited by engagement of shoulders 58 and' GO with the under sides of the collars 50. The shoulders 60, which are located in the rear end of the pivots 56, contain springs 62 which bear against the collars 50 and normally hold the hangers tilted forward as far as the shoulders 58 permit, as shown in Fig. 17. In this forward position of the heelsrest the platek is .out of contact with the yoke, so that the heel-rest is free to swing laterally, but
`when the rest engages the shoe it is moved backwardly far enough to cause the plate 70 and the surface 68 of the yoke to come into frictional contact, and when these parts are in contact the heel-rest is locked against lateral movement. The springs 62 are strong enough to hold the heel-rest away from the yoke where it is free to move laterally, until the rest, yin its forward movement imparted by the spring 14 and the block 12, meets the shoe. As the rest comes into contact with the shoe it is moved laterally by its inclined faces 41, 41 as they meet the shoe and automatically adjusts itselfV laterally according to the shape of the last and the position which the shoe has assumed in the machine. Vhen the rest is so pressed against the shoe it will yield backwardly against the tension of springs 62 until it meets the roughened surface 68 of the yoke and thereby becomes locked against anyrv subsequent lateral movement during the 0peration of the machine. Y
The heel-rest actuating mechanism above described, including the block 10, acts t0 move the heel-rest forwardly automatically until it comes into Contact with the heel of the shoe, after which the spring 14 yields during the further movement of the block. rlhe extent of this movement of the heelrestv is sufiicient to accommodate considerablek variation in the length of lasts. For accommodating widely differentlengths ofi lasts the heel-rest maybe adjusted backw'ardly and forwardly by uncoupling the shafts 30 and 32 in the.y mannerabove de-7 scribed. Nhen these shafts are uncoupled the heel-rest `maybe shifted 'freely either backwardly or forwardly` into the desired position. ln this movement the sleeve shaft 32 turns idly on the shaft 30, and when the proper adjustment has been found the shafts 30 and 32 may be again coupled, and there-y after the heel-rest will be operated in its new position by its actuating mechanism.
If it is desired to discontinue the auto matic actuation of the heel-rest the shafts 30 and 32 may be disconnected by drawing the loose collar 3G to the left in the several figures, as above described, and then turning it until the fingers 38 are out of alinement with the recesses 40 and in position to rest against the lefthand side of the collar -34 on the shaft'30. This uncouples the collar and its shaft 30 from the sleeve shaft 32 and permits the sleeve shaft, and therefore the heel-rest, to remain unmoved while the shaft 30 continues to be. automatically oscillated.
The yieldingly effected, automatic advance of the heel-resttakesplace during the` first part of the movementof the grippers for drawing the upper taut around the last and is preferably just suflicient to bring the `heel-rest into operative position against the heel of the shoe, but is not designed for moving the shoe forwardly. The spring 14 could, of course, be made strong enough to cause the shoe to be pushed forwardly by this mechanism if desired.
It is sometimes desired in pulling-over shoes to give the upper a backward and upward pull over the ball after it has been pulled straight upwardly. This is known as back-lasting and isvaccomplished when shoes are pulled over by hand, by turning the pincers and giving the upper a pull angularly across the last. 1n the machine herein shown the same result is obtained by giving the last a forward movement into the suspended upper during the last part of the rise of the grippers. This causes the side grippers to pull the upper backwardly and upwardly and so draw the upper firmly over the ball of the last. I have in this embodiment of my invention moved the shoe forwardly by means of the heel-rest and for this purpose have provided for the heel-rest actuating mechanism now to be described.
The block 10, which is actuated directly and positively by the cam groove 6, as before described, is provided on it-s lower face with a lug 80 for engaging one arm 82 of a bell-crank lever 84 which is mounted on a xed stud 86. The other arm 88 of the bellcrank lever rests upon aplunger 90, which carries at its lower end a pawl 92 comprising part of `the heel-rest actuating mechanism and a pawl 94 comprising part of a mechanism hereinafter referred to. The pawls 92 and 94 are adapted to engage ratchet wheels 96 and 98. The plunger is depressed by the bell-crank lever against the tension of a returning spring 100-see Fig. S--when the block 10 is moved. to the left in Fig. 4. The pawls 92 and 94 are acted upon by springs 102 to force them against the ratchet wheels 96 and 98. Controlling devices 104 and 154 for disengaging the pawls from the ratchet wheels are adjustably mounted on a. fixed portion of the frame-see Figs. 4, 15, and 1G--in position to Contact with the upper ends of the pawls and disengage them from the ratchet wheels as the plunger 90 rises. These controlling devices hold the pawls away from the ratchets until the pawls pass them in the descent of the plunger. The position to which the controlling devices are adjusted determines the port-ion of the downward stroke of the plunger during which each pawl is allowed to engage its ratchet, and therefore determines the extent of movement imparted by the plunger to each of the ratchet wheels.
The ratchet wheel 96 is formed on a sleeve shaft 150 which carries a pinion 152. The pinion 152 engages the rack-teeth on Oneot' the heel-rest carrying bars 48. The positive movement of the cam-operated sliding block 10 is therefore transmitted through the plunger 90 and said sleeve shaft 150 to the heel-rest carrying bars 48, to force the heelrest, and therefore the last, forwardly into the suspended upper. This movement preferably takes place during the last part of the rise of the grippers and strains the upper backw'ardly over the ball of the last.
The sole-rest is actuated for moving the inner-sole by mechanism including the pawl 94 and the ratchet wheel 98 above mentioned. The ratchet wheel 98 is formed on a shaft 110 independently movable inside the sleeve shaft 152, said shafts extending transversely of the machine, parallel with the shafts 30 and 32 as shown in Fig. 9. The shaft 110 is provided with a pinion 112 which engages with rack-teeth formed on a bar 114 slidably mounted in the post 12 of the machine frame, as shown in Figs. 3, 4 and 9. The bar 114 is provided at its rear end with a spring 115 which abuts against the machine frame and which tends to hold the bar in its rearmost position and the bar is pivotally connected by a link 116 to the shank-118 of the sole-rest. The shank of the sole-rest is guided through a sole rest carrier 120 which is mounted on a fixed pivot 122. The shank 118 is provided with a T rib which is received in a suitable guideway in the lower face of the carrier 120, as indicated in Figs. 4 and 5.
The sole-rest comprises two laterally and forwardly extended arms 124, 124 for engaging the inner-sole near its edges, and a forwardly extended arm 126 having a foot piece for engaging the inner-sole near the toe end thereof. The arms of the sole-rest are provided with roughened extremities or feet for frictionally engaging the inner-sole to prevent the rest from slipping with relation to the inner-sole and enable the rest to move the inner-sole with relation to the lastfor a purpose to be described. The arm 126 of the sole-rest is adjustably connected to the shank 11S-see Fig. 7 to adapt the solerest for properly engaging inner-soles varying in length. This connection comprises a spring-pressed bolt 128 mounted in the shank 118 and adapted to engage any one of a series of notches in the arm 126.
The foot-piece 130 of the arm 126 of the sole-rest is adjustably attached to said arm, as shown in Fig. 4. The foot -piece is mounted on a pivot 132 and its rear end is acted upon by a spring 134 which tends to tip the forward end of the foot-piece upwardly.
136 indicates a stop screw mounted in the foot-piece 130 and which may be adjusted to determine the position in which the spring 134 shall hold it. This adjustment is desirable for determining the vertical position of the toe of the last with relation to the toe grippers. Some shoes have a thick bulk of upper material at the toe, formed by the toe-cap7 stifener, and linings in addition to the upper, whereas other shoes have less thickness of upper material to be pulled over by the toe grippers. lt is advantageous when there is a considerable thickness ot' the upper material at the toe to have the shoe held lower than whenthere is less thickness, and the foot-piece 130 may be adjusted accordino' to the class of shoes being operated upon.
rElie carrier 120 in which the sole-rest is movable is provided with aniarm 13S which is engaged by a cam 140 carried on thetront end of the shaft D. Ther cam tips the carrier 120 on its pivot 122 to forcethe solerest downwardly at a certain' period in the operation of the machine. The carrier is tipped in the opposite direction by a spring 142 mounted in a chamber in the rear end` of the carrier and bearing against a fixed portion of the mach-ine, as shown in Figs. 3 and 4. This mechanism operates, after the machine is started and while the upper is being pulled taut about the last by the grippers, to sink the last downwardly into the upper.
The pawl controlling devices 104 and 154 may be adjusted to render the pawls 92 and 94 operative or inoperative for moving the sole-rest and the heel-rest. lNhen said pawls are rendered operative the controlling devices determine the portion of the strokes of the pawls which shall be effective for moving the sole-rest and the heel-rest and thereby determine the extent of the forward movement imparted to each of said rests. When it is desired to move the shoe forwardly without changing the position of the inner-sole on the last the controlling` devices are adjusted for giving the two pawls the saine amount of movement so that the solerest and the heel-rest shall be moved forwardly the same distance.
When the inner-sole is loose on the last and it is desired to move it forwardly over the bottom ot' the last to bring vits toe end 'lush with the toe end of the last and simultaneously to move the last forwardly, the controlling device `forthe sole-rest actuating pawl will bek so adjusted as to render the sole-rest actuating pawl operative for a greater portion of its movement than Vthe heel-rest actuating pawl.
lVhen the inner-sole is loose on the last and it is desired to move the inner-sole forwardly without moving the last the pawl controlling device for the heel-rest actuating pawl will be so adjusted as to render the said pawl inoperative and the pawl controlling device for the sole-rest actuating pawl will be so adjustedas to render the sole-rest actuating pawl etlective during the necessary portion of the stroke of said pawl for producing the desired movement of the sole-rest. 1t is to beunderstood th'atithe inner-sole is loose on the last, that is unattached to it, the sole-rest imparts no movement whateverto the last, but merely moves the inner-sole kwith relation to the last. lf however the` inner-sole is fastened to the bottom of the last by tacks or otherwise, as is sometimesdone, the sole-rest assists the heel-rest in moving the last forwardly, or the heel-'rest actuating pawl might be rendered inoperative andthe sole-rest alone be employed for moving the last by means of the inner-sole' secured to it.
1 It is sometimes desirable to move the heelrest vor the sole-rest, or both of them, farther ij'orward after the machine has given to thesep-arts their automatic movement, as above described. At other times it is desirable to-discontinue the automatic operations of the sole-rest and the heel-rest for moving the inner-sole and last respectively and manually move said parts as required. For this purpose the machine is caused to come to rest after the upper has been stretched and after these automatic movements have been imparted to the sole-rest and the heel-rest. A hand lever 160 is provided which is attached to the shaft 110, to which shaft is also secured the ratchet wheel 98, as shown in Fig. 9. The hand lever carries a spring-pressed pawl 164 in position to engage the other ratchet wheel 96, as shown in Figs. 8 and 10 so that said hand lever is normally connected to both the shaft 110` of the sole-rest operating mechanism and the sha-ft 150 of the heel-rest operating mechanism. The pawl 164 has a lateral arm 163 whichstands in the path of a device 162l which may be operated to disengage the pawl 164 and also the pawls 92 and 94 from the ratchets 96 and 9S. The
pawl disengaging device 162 is pivotally connected to the hub of the hand lever at M35-see Figs. 11 and 12-and has a fingerpiece 166 standing alongside the lever in convenient position to be operated in connection with the lever. rThe pawl 94 has alug 174 which also stands in the path of the disengaging device, so that thetwo pawls 94 and 164 may be disengaged simultaneously from their respective ratchets. The pawls 94 and 92 are connected by a stud 176 on the inner side of the pawl 94 which enters a slot 177 in the adjacent face of the pawl 92-see Fig. 11. The slot isV of sufiicient length to allow the stud a limited amount of :tree movement, after the disengagingdevice contacts with the lug 174 and begins to move the pawl 94 before the pawl 92 is moved. y n
The pawl disengaging device 162 is held normally in therposition shown in Fig. 4 by a spring-pressed plunger 16S, mounted in a socket in the hand lever, and bearing against the iinger-piece 166. The socket inthe lever also contains a second plunger-170, located in the rear of the plunger 168 and actuated by a spring stronger than the spring which actuates the plunger 168.
When the finger-piece of the disengaging device is depressed to force the pawls away from the ratchets, the plunger 168 will yield readily until its spring has been compressed, as shown in Fig. 11, whereupon the resistance of the second plunger will be encountered and thereafter, ifa stronger pressure is applied to the finger-piece than was necessary to depress the rst plunger the second plunger may also be depressed, as shown in Fig. 12. This arrangement is such that the operator may with ease depress the finger-piece to the extent allowed by the first plunger to cause the pawl disengaging device to assume one position, but a distinctly greater pressure will bev required to depress the fingerspiece to overcome the stronger spring of the second plunger and force the disengaging device into its second position.
When the parts are in their normal position, as shown in Fig. 5, the pawl 164 on the hand lever, is in engagement with the ratchet 96-see Figs. 8 and 10-and when the hand lever is turned toward the dotted line position-Fig. -bot-h the ratchets 96 and 98 are turned while the pawls 92 and 94 act as stop pawls to prevent reverse movement of said ratchets. This rota-tion of the ratchets advances both the heel-rest and the sole-rest together to force the last forwardly into the suspended upper.
Sometimes it is found to be necessary to give the sole-rest a forward or backward movement independent of the heel-rest after the automatic operation of the machine to position the inner-sole accurately on the last, or, if the inner-sole is tacked to the last, to move the lastl forwardly or backwardly. Then this is necessary the pawl disengaging device is depressed into its first position in which it disconnects the pawl 164 from the heel-rest operating ratchet 96 and also holds the stop pawl 94 olf from the sole-rest ratchet 98. The hand lever 160 is then free to be turned to rotate the shaft 110 alone in either direction to move the inner sole over the last.
At other times it may be desirable, in order to readjust the last in the upper, to release the heel-rest and let it move backwardly the distance which it has been positively advanced in the back-lasting movement. This can be done by moving the disengaging device into its second position, shown in Fig. 12, whereupon the stud 176 on the pawl 94 will move pawl 92 out of engagement with ratchet 96 to release said ratchet. The heel-rest is then free to be moved backwardly by the tension of the stretched upper.
It will thus be seen that the hand lever will no-t only move the sole-rest and the heelrest forwardly together, but it may also be used to move the sole-rest backwardly and forwardly whileV the heel-rest is locked against movement, and further, the heelrest may be released and permitted to move backwardly independently of the sole-rest. It isto be noted that the heel-rest is given an initial forward movement by the cam 6 acting through the spring 14 and that the spring yieldingly holds the heel-rest in the forward position to which it is moved. Vhen the hand lever is operated to advance the heel-rest still farther, the force exerted through said lever by the operator is in addition to the force of the spring and therefore need be but slight in order to eect the movement of the heel-rest and the shoe supported thereby.
In o-rder to permit the heel-rest to return to its normal position if it has been given a manual adjustment in addition to its automatically imparted movement it is necessary to disengage the pawl 164 of the hand lever from the heel-rest operating ratchet 96 after the operation of the machine on one shoe has been completed and before the operation on another shoe is begun. For this purpose a lug 167 is secured to the machine frame, as shown in Figs. 1 and 10, and stands in the path of the pawl 164 to disengage said pawl from its ratchet as the hand lever swings to the rear beyond its central, normal position. The ratchet 96 is then free to rotate independently of the hand lever and of the sole-rest ratchet, to permit the heel-rest to resume normal position under the influence of spring 14.
The shoe is supported for the insertion of the fastening tacks by mechanism comprising arms 20X and 22X (Figs. 1, 2, 20, and 21) pivotally supported on the head of the machine at 18X for horizontal movement together toward and from each other. The arms are in the form of bell-crank levers, and their rear ends are engaged by rackteet-h on bars N24, N28 which are moved by a slide N26. The slide carries a stud N34x which is acted upon by the cam N33, whereby said slide is reciprocated to actuate the arms 20X, 22X. The movement of the bars N24, NZS by the slide N2G to cause the last-supporting arms to approach each other is yieldingly effected through springs i 44, N40 and an equalizing device NT, all substantially as sho-wn and described in detail in Letters Patent of the United States, No. 950,701, granted to me March 1, 1910.
The arms 20X and 22X carry on their free ends combined mechanisms for supporting the last and wiping and pressing the pulled upper into position to receive the securing tacks. These mechanisms will preferably be constructed as shown and described in saidprior Patent No. 1,029,387.
mf-gagement with a stud 326x on a secondj slidev They to'e portion of the upper iswiped and pressed into position for receiving the fasten-v l ingl `tacks by the A combined wiping and vtackcarrylng mechanism indicated atl, lin Fig.
This mechanism preferably :will be the same as that shown and described in Letters Patent No. 950,701, before mentioned and therefore is not shown or described'in detail herein.`
The mechanlsmfor pulling the upper t-o stretch VitA around= the last comprises grippers 7SX mountedon/shanks 68X.' The upper ends Aof the gripper shanlrs are pivot-ally connected to the levers 154", 154x, and e which are fulcrumed on a pivot shaftl Vin the machine head-and acted uponby cams X30 and 188x,- as heretofore described, whereby said levers arefrocked to lift the-grippers and pull the upper. The machine comprises mechanism which includes springs X316, one
of which is shown in Fig. 3, formoving the grippers 'inwardly over the shoe to over-f draw the upper into vposition to receive the fastening tacks; and also-comprises-mecha- .nism for i moving the grippers outwardly against the tension of the-springs X316 in-to position to grip the upper. The Amechanismv for moving the'grippers outwardly also acts for `holdingsaid grippersin such outward position during the'up-draw movement imengaging -rack-teeth 820X on the slide 818".
The slid-e 81SX actuates aslide 638K which is provided wit-ha depending lug S40.X inen# 322x having an arm for engaging thelshan'lsv 68X of the toe grippers and a connection-not shown-with theside grippers. Y These mechanisms may be the same as the mechanisms .ifor these purposes showntand` describedin Letters PatentNo. 663,777 before mentioned. The'operationof pulling-over a 4shoe as carried outby this machine-isbriefly stated f as follows: The shoev isk presented' by vthe.`
.5o-workman Abottom upward to the-machine,
6o iSimultaneously withffthe "actionf-of the grip-1f with'the inner-sole against'the sole-rest and withthe outwardly and upwardly extending..
edges of the upper andl lining materials between the open Jaws of the-grippers. The
igrippers yare first closed to grip the.V upper and then-raised to pull `it 'about the last, the
last being held froml upward movement 'by the sole-rest.' Preferably the toe grippers are put into-action first vto pull and thereby straighten t-he -upper longitudinallyy over 'the face of the last; and then the side ygrippers are' brought into actionJ to pull the `sid'es of the upper andshapelthe upper to' the last alongf'theA ball-and instep parts ofjthelast.
pers in pulling thek rippen-the heel-rest is"` moved forward into supporting engagement* Iwith'the-heel end of the last.- The grippers'- actuating mechanism and the heel-rest actu-- ating mechanism are so timed that the grippers will firsthave pulled the upper enough tofhave pressed the shoe firmly against the sole-rest by the time` the heel-rest comes into supporting engagement with the heel of the last.' While the sidey gripper-s are still'moving, the sole-rest lcarrier is rocked about its pivot by thecam 140 to depress thev toe'lpor-` tion ofthe-last against thef tightly strained upper for sinking the last downwardly into f the :upper and causing the upper to conform Xto the shape of the last. The sole-rest and the heel-rest inf-the `normal adjustment of the machine are moved forwardly duringthe latter part of'vthepulling movement of the grippers, the sole-rest, it may be,-acting lto auf force thev inner-soleV forwardly on :the last L to bring its toe end iush with the toe end of ,the last and in contact with the upstretchedy toe portion of the upper, and the heel-rest actingto carry the last forwardly with rela- `tionto the upper as the latter is held by the f grippers` and thereby cause theupper to be strained backwardly over the last, particularly` alongthe-ball portion of the last while itis pulled taut by theside-grippers, whereby this portion of the upper is made to conform tothe linesy of the lastover the-ball.
These operations having taken place the ma-` chine is' brought'to restto ypermit the operi ator to examine theshoe and, ifv necessary,
manually "to shift the-heel-rest or the solerestor both of them,by means of the hand lever 1GO to adjust the last and to position the inner-sole, if, upon inspect-ion, he finds'f that theseoperations have not been .completely andv satisfactorily performed for the particular shoe invhand by thefautomaticvop'- eration of the machine as just described.
When the machine is re-started, the arms carrying the last-supporting and wiping .and pressing mechanisms are moved into position against the sides of the last by the action of the camll?3 on the slide N26, andl as the last-sunorts and wi ders and ressers come 1 into engagement with the `upper on .thesides of thelast, the grippers are moved inwardly over the=last to over-drawfthe upper and then they release' the upper. The grip-pers are followed closely 1n their movementover the inner-sole of theshoe vby the tack-carrying blocks and the drivers by which the tacks i are inserted at the toe'and at the sides to securethe pulled-'over upper to the innere' SOle;
