Application led March 2, 1915, Serial No. 11,596.
To all whom it may concern:
Be it known that I, ANGELO FERRI, a citizen of the United States, residing at Haverhill, in the county of Essex and State of Massachusetts, have invented certain Imrovements in Assembling and Pulling-Over /lachines, 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 in general tomachnes for use in the manufacture of boots and shoes, and is herein shown as embodied in a. machine for use inassembling the parts of boots and shoes on a last and for thereafter subjecting the assembled parts to a pulling-over operation. It should be understood, however', that in its broader aspects and lin many of its features the invention is not necessarily limited to machines for performing these particular operations in shoe manufacture.
upper,
Heretofore it' has been common practice in most shoe factories to assemble the shoe materials, which include a lined a counter and an innersole, on a last in proper relation for the subsequent shoe making operations, either by hand or with the aid of an assembling machine, and to secure the assembled parts by one or more tacks which are driven through the materials and into the last. The last and the assembled shoe are then removed from the jack or support, and subsequently the shoe upper is pulled over, this operation being most commonly performed by a pulling-over machine. This practice not only consumes considerable time, but in the removal of the shoe from the support or jack on which the assembling operation was performed and its transfer to the pullingover machine there is more or less danger of disarranging the shoe materials on the last and especially at the fore part of the shoe, as the tacks which secure the assembled lupper, counter and innersole in position are ordinarily driven into the rear end of the last. It is highly desirable that these parts should be assembled on the last before the shoe is pulled over in the exact relative positions which they are to occupy in the finished shoe, and, when once properly as- Speciication of Letters Patent.

sembled, it is equally important that said parts should be maintainedpin such relation until they are finally secured together, as the appearance and durability of the shoe are largely dependent thereon.
It is one of the principal objects of the present invention tosecure and maintain the exact relation of shoe parts on a last in the interval between different operations 0n the shoe. To this and other ends, an important feature of the invention resides in a novel construction and arrangement including shoe positioning means which is movable from one position to another to permit the shoe to be presented alternately for the performance of di'erent manufacturing operations. The construction shown as embodying this feature comprises a shoe support or jack which is constructed and arranged to hold a last in a given position while the upper, counter and sole or innersole of a shoe are being assembled thereon, and is movable for carrying the assembled shoe parts into a different position to present said shoe to pulling-over mechanism.. The shoe is thus assembled and pulled-over on a single machine, and hence without the necessity of transporting the last and shoe materials after the assembling operation to a dilfercnt machine, which might mean carrying said parts to a diHerent part of the shoe factory.
In the construction herein shown the shoe support is pivoted to chine so as to swing about a center, and is arranged to present the shoe with its sole vface upward during the assembling operation, and to move through an arc of approximately 90 degrees to carry the assembled shoe to a position slightly inclined to a vertical plane, where it will be in operative relation to the pulling-over instrumentalities. `When in the latter position the top portion of the shoe will be in full view of the operator as he stands in front of the-machine so that he can observethe position of the upper and all of its parts, including the tip seam, and will thus be able to detect any incorrect positioning of said parts, and
to make such adjustments as are necessary to correct the saine.
Another important feature ofthe invention consists in novel means for .retaining the heel end portion of the shoe in correct the frame of the marelation to the last, the construction shown comprising a heel bandvor clasp whlch 1s shoe parts in assembled relathe pulling-over operation. shown, such clamping is made to occur as the assembling jack or shoe support swings from assembling to pulling-over position. The heel band acts to hold the front ends of the counter tightly to the sides of the secure the upper and counter firmly to the last while the'assembling tacks are being driven, and unt-il the shoe 1s pulled-over and the upper secured in pulled-over position. The heel band is furthermore automaticallyv opened to release the shoe when the shoe support is returned, subsequently to the pulling-over operation, tothe position it originally occupied, so that the pulled-over shoe lnay be removed and another last with the shoe materials which are to be assembled arranged loosely thereon. may be placed on the support.
Another important feature of the invention is found in the mechanism which drives the tacks for securing the assembled shoe parts at the heel end of the last. In the illustrated embodiment of the invention this mechanlsm includes two tack-drivers driver for driving a tack through the upper, the counter flange, and the sole or innersole, at the rear end part of the last bottom, and suitable means for feeding tacks beneath said drivers. Preferably7 the tack drivers are constructed and arranged to be retracted against lthe force of their driverspring by mechanism which is actuated by power derived from the main power shaft of the machine, and are subsequently tripped and drive the tacks through the asmaterial, said operations beis moved to carry the assembled shoe into pulling-over position.
Another feature of 'importance is found for clamping the last firmly to the support, and comprises a bottom rest which, in the construction shown, is spring-pressed, and is arranged to engage the last bottom beneath the heel and in substantial alinement with a springpressed jack pin. The bottom rest clamping member'has a stem which slidesin a rigid part of the shoe support, and the end portion of said stem arranged to engage a rigid abutment when the shoe support swings the shoe into pulling-over position. thereby forcing said member against the shoe which is tlms clamped firmly at the heel end bysaid members, and additionally by the heel band.
lThe upper of the assembled shoe is pulledby mechanism comprising, in the preferred embodiment of the invention, three pincers, one being located at the toe end and one upon each side of the fore part of the last. In the construction shown manual means is provided for first causing the pincers to close upon the margin of the shoe upper, and then, by a continued movement to apply to the upper a yielding pull and to strain it to the lastl` but in its broader aspects the invention is not limited to manual means for operating the pincers. Important features of novelty reside in the pincer operating mechanism, the illustrative construction comprising a hand-operated lever and a novel arrangement of connections with the pincers that enable the operator after inserting the margin of the upper between the jaws of the pincers to cause by a single movement of the hand lever the pincersto seize and then to pull the upper. This may be a preliminary pull of it just a sufficient amount to hold the upper snugly about the last. and in the construction shown is positively limited in eX- tent. This preliminary g Q preceded b v any adjustments of the upper upon the last that are found to be necessary.
he operator then may make another inspection of the upper, and if it has been pulled in proper relation to the last. a sec` ond and final pulling strain is applied. In the illustrated construction this second pull is applied through another hand lever and connections with the pincers, said connections being of acharacter to apply a greater amount of power to the pull than was applied through the first-mentioned lever and permitting a pull of indeterminate extent to be effected. As shown, a continued movement of the secondv pulling lever by the operator will trip a latch and leave the pincers, and their support. free to move away from the shoe when the pincer jawsl have been opened by a subsequent operation of the machine.
Another important feature of the invention is found in an improved means for clamping the oe at the fore part of the last prior to the release of the upper by the pincers` so as to maintain the upper in its pulled-over position until the tacks which secure it have been driven by the fore-part tackers. this feature of the invention this means consists in part of a toe end clasp. and in part of an upper pressing-pad. The toe-end clasp. under the present invention. comprises a band of flexible material. such as sheet steel, having a lining of felt. or other soft material, provided with teeth so as to fric` straining is usuallv In the illustrated embodiment of tionally engage-the upper leather, but without mai-ring the surface thereof. The clasp is preferably connected with yieldinglyvactuated arms which hold the clasp normally open or extended. The clasp is supported by a carrier which slides in a guide sustained by the frame of the machine at a .distance from the toe end of thel shoe, but in alinement therewith. The upper-pressing pad is also supported normally at a distance from the toe end of the shoe. After the nal pull has been given to the upper, the operator again steps on-the treadle which starts the machine and, through suitable mechanism, the clasp is moved against the toe end of the shoe and is wrapped about the fore part thereof, and the upper-pressing pad is ,also moved against the upper at .the top of the I last and the upper is pressed down into the depression found at the rear-of the high toe in modern lasts. Immediately following these operations the power-actuated mechanism of the machine eects an opening of the pincer'jaws by interrupting the connection between the pincers and the lever through which the jaws were closed, and the pincers are then moved away from the last 'to pro-vide room for the fore-part tackers.
driving devices, one being arranged for use at the toe-end, and the other two for use at the sides of the shoe tothe rear of the toe. These devices are preferably -supported lby the same carrier that supports the toe end clasp so as to bemoved into and out of opened to release the upper and are immediately moved away from the shoe to make room for the tackers, and the machine is again brought to rest before the tackers have been moved completely into operative relation to the shoe. These tackers, besides being movable as an entirety toward and from the shoe, are in the illustrated vembodiment of the invention-'capable of additional movements, the two side tackers being foldable in against the sides of the shoe, and all three of the tackers turning through an are of ninety -degrees so as to ride over the edge of the fore part of the shoe and slide in upon the margin of the shoe bottom. The tackers have at their bases rounded corners which during these movements press the upper against the edge of the innersole, and force it snugly into the corner or angle at the junction of thelip and the feathered edge. The described movements of the tackers serve to smooth out the wrinkles in the margin of the upper and to hold it firmly in the position where it is to be fastened until the tacks are driven. The tacks are fed in position below the drivers by any preferred tack feeding devices, and are retained in such position until driven into the shoe. The tack-driving blow is delivered to the three drivers simultaneously while they grouped'about the fore part of a shoe by a spring-actuated lever, which is pivoted to the tack-driver carrier, and has connection with the frame of the machine so as to be moved away from the tackers to store power inv its spring and thus be set in condition for operation, automatically, as the carrier is moved away from a shoe, being retained in such position by a suitable latch. When the tackers are moved in over the edge of the v shoe a continued operation of the machine causes movement of the latch to trip the lever and thereby effect driving of tacks to secure the pulled upper to the innersole. Following this operation the power-actuated mechanism returns the fore-part tackers, the toe-end clasp, and the upper pressing pad to their formerly-'described positions in which 4inafter more particularly described and claimed.

Fig. 6 shows the toe clasp, and
`Fig. 7 is a perspective view of the forepart tackers in operative relation to the fore-part of a shoe.
The machine frame comprises a base A, and a head B which extends upward from the base and supports the mechanism for use in assembling the shoe parts and securing them at the heel end of a last, and for pulling-over the assembled shoe parts and securing them in pulled-over position.
The base A supports in suitable bearings a shaft 99 carrying a loose pulle)v 100, to which ma)v be applied a belt for receiving power from a suitable source. The pulley 100 is preferablyv arranged to be connected to the shaft 99 by a clutch, and the movable member 103 of the clutch carries a pin which is adapted to engage a wedge 102 connected to an eccentric pin, or the equivalent, at one end of a rod 101, which is rotatable in bearings carried by the base A., and carries at its other end a treadle 12. When the treadle is depressed the. wedge will be withdrawn thereb7 releasing the movable clutch member which will be spring-pressed into en-.
gagement with the loose pulley and clutch it to the shaft 99. Then the treadle is released the wedge will be caused by a spring (not shown) to rengage the pin carried b v the movable clutch member when the shaft has completed one rotation and will withdraw Said member from lengagement with t-he loosel pulley, and the motion of the shaftwill then be arrested.
The inner end of the shaft 99 carries a. beveled gear 106 which meshes with a beveled gear 108. The latter has three times the number of teeth of the gear 106, and is fast to one end of a shaft 110 which rotates in bearings carried by the frame base. The shaft 110 has fast toits otherend a beveled gear 11'2 meshing with a beveledgear 111, carried by a shaft 116, thatis also rotatably supported in bearings in the frame base. A cam 11S is fast to the shaft 116, and a rod 120. which reciprocates in a guide supported by the frame, carries at one, end a cam roll .r that engages the cam 118, and at its other end is connected b v a ball and socket joint with one arm of a bell-crank 122 that is fulcrumed to a bracket 21 projecting rigidly from the frame head B. The other arm of the bell-crank has pivotal connection with one end of a link 8 whose opposite end portion has a slot S which receives a pin 9 projecting from a transverse bar 11 which car ries lugs for pivotally supporting the rightangular shaped pawls 15. 15. vfor setting and releasing the tack drivers for use at the heel end of the shoe. The b ar 11 is rigidlv attached to a. slide 10 whlch is guided in its movements by bars 10", 10, projecting rigidly from a block Z. This block is secured firmly to an arm 7 which has a pivotal connection 3 with a .cam-shaped extension 21a of the bracketQl'. The arm 7 is arranged to swing about the cam-shaped extension, and carries guiding lugs f, g, for a pin 1 which slides in perforations in the lugs, and a spring 1, confined between an abutment on the pin and the lug g serves to, yieldinglv hold the inner reduced end of the pin in the jack pin hole of the last which carries the shoe parts. The thrust of the pin 1 is opposed b v a heel rest 130 whose. stem slides in a hole through the block Z, and carries a button 133 at its outer end. and a spring 131 surrounds the stem'of the heel rest and is confined between the button 133 and the inner face of the block.
The bracket Q1 carries an internally threaded lug which receives an adjustable stop screw 132, arranged in position to engage the button 133 when the arm 7, constituting the jack, is swung from shoe-assembling position as shown in Fig. 3, to pulling-over position, as shown in Fig. 1, whereupon the springs 131 and 4, being oompressed. will re-ac-t through the jack pin and heel rest to clamp the shoe yieldingl)v in position for the operation of the pullingover devices.
The driver 13, for driving the tack through the assembled shoe materials on the last bottom near the rear end of the sole,- which materials include t-he innersole, the lined upper and the flange of the counter,- slides through a. perforation in the block Z and has a driver bar 13b which passes loosely through a guide-opening in the transverse bar 11. This driver bar carries a pin 13c which is acted upon by one end of a spring 13a'whose function is to force the two drivers toward the shoe bottom. The driver 1i for the tack that is driven through the assembled shoe materials at the back of the heel is arranged at right angles to the driver 13, and has connect-ion with one arm of a bell-crank 110 which is fulcrumed to the block Z and has its other end pivoted to the driver bar 11a. This driver bar has a pin llcwhich is acted upon by the other end of the spring- 13a. The upper end portions ofthe driver bars have inwardly projecting lugs e that are engaged by the outer ends of the pawls l'which are acted on bv springs confined between the inner ends of these pawls and the bar 11. When the bar 11 is raised the driver bars will be lifted, thereby putting the spring 13a under tension. A continued movement of the bar 11 causes the inner ends of the pawls to engage the pins carried b v the guides 10a. thereby tripping the pawls and permitting the spring 13a to actuate the drivers 13l andli. and drive the two tacks that hold the assembled 4shoe materials in position at the heel end of the last. The tacks, preferably in strip form, are fed successively below the drivers' 13, 14, prior to each Jdriving operation, by any suitable automatic tack-feeding mechanism.
The flexible 'heel band 5, which clamps the shoe materials rmly about the heel end of the last after the assembling operation and prior to the pulling-over -of the shoe, is preferably cut away at its rear oe-ntral portion, in line with the tack driver 14 to provide for driving the tack through the upper and counter at the rear of the heel without penetrating the band. An important function ofthis band is to press the counter, and especially its end portions, firmly against the heel end of the last, and to hold the counter and thev upper thus pressed while the tacks are being driven by the drivers 13 and 14 so as to prevent displacement of these shoe parts until they are secured in position by the tacks. The heel band is pivotally supported near its outer ends upon the curved arms 6 of a bell-crank which is fulcrumed by la pin 6a to the block Z. The bell-crank has an arm 6b which carries a cam roll 50a engaging vthe camshaped extension 21a ofthe bracket 21.- A spring 6c, which may be .coiled around the pivot pin 6a, acts against the arms 6 of the bell-crank,"and serves to force the ends of the heel band forwardto wrap the band about the heel end of the shoe when the arm 7 is swung about its -pivot from the Vposition shown in Fig. 3 to that shown 'in Fig. 1, the cam rolll 50a passing from the highl to the low part of the cam 21a during this movement of the arm When the arm is swung reversely to carry the shoe from the position shown' in Fig. 1 to that shown in F ig. 3, following a pulling-overoperation, the cam roll passes from the vlow .to the high portion of the cam and the arms 6 of the bell-crank are moved rearwardly, thereby opening the heel band and releasing the shoe.
A rest 16, having spaced feet to engage the bottom of the sole at the fore-part of a shoe, lhas a threaded stem 16() which slides in a hole in a plate 162 and is held from turning therein by a pin 16"l andgroove 16h. A winged nut 161 is threaded tothe stem and bears against'the plate.V The plate 162 is provided with a slot, and a' clamping bolt 163 passes through the slot and has threaded, engagement with the bracket 21. The rest 16 is adjustable toward and from the shoe bottom by means of the wingednut 161, and is adjustable in a plane substantially parallel with the shoe bottom by unscrewing the clamping bolt 163 and moving the plate in the direction of itspslot.
The pincers for pulling-over the shoe are preferably three in number, one being located at the center of the toe end of thev shoe, and one on each side and substantially at the end of the toe tip seam. The pincer shanks 170, 170% 17 0b terminate in rigid jaws, and a coperating movable jaw 17 is l sufficient tension to force the rods rearwardly, when not prevented from doing so, thus holding the pincer jaws open. The shanks 17 0l and 170b of the side pincers are vconnected with each other by a bridge 18 which has near its ends slots, and pins or yscrews 20 pass through the slots and are secured to the pincer shanks, whereby the side pincers may be adjustedl different distances apart for shoes of varying widths. An adjusting screw 174` has its inner end connected centrally to thebridge 18 with capacity for turning movement, and is externally threaded to engage a thread in a nut 174'nl which is trunnioned in the walls of a slot through the pincer shank 170. The outer end of the screw 174 is provided with a hand wheel, as shown, which may be manipulated for turning the screw in either direction to thereby position the toe-end grippers different distances from the side vgrippers for shoes of different sizes.
-The pincer shanks are connected pivotally at their rear ends with sleeves 28, 28a, 28", the central sleeve 28 being connectedv with vthe shank of the toe-end pincer, while the sleeves 28@L and 28b are, respectively, connected with the shank of each side pincer. The sleeve 28 is supported for sliding movements upon a rod 35 to which the sleeve is connected by a slot 240, and a pin 241 on the rod, for limiting the extent of such movements, and the sleeves '28a and 28b are similarly supported upon rods 135a andlb, and are likewise limited in their sliding movements thereon by slot and pin connections as shown in Fig. 2. The rods 35, 135% 135b are rigidly connected with each other at their forward ends by a bar 39, and springs 136 surround the rods and are confined between the bar and the sleeves 28,28a and 28".
The rods 171 for'closing the pincer jaws are connected at their rear ends by socket joints withl bell- cranks 176, 17 6a, 17 6b, whoserear arms are acted upon by cams 22, 22a, 22", pivotally supported upon the rods 35, 135% and 1351. rlfhe cam 22 has its outer free end connected by a pin with'a slot 181 ball and i are,
in one end of a rod 178 and a spring N eX- ried by the bridge 39. A block 179 is secured to the rod 178 and is provided with perforations, one on yeach side of the rod 178, to receive two short rods 178", 178". The inner ends of these rods are slot-ted at 181 to receive pins on the outer, free ends of the cams 22 and 22".- 'Spiral springs 180 surround the rods 178, 178", and are confined between nuts threaded to the outer ends of these rods and the block 179, thus providing yielding connections between the rod 178, and the rods 178a and 178".
The rear end of the rod 178 is pivoted to e one arm of a lever 37, which is fulcrumed to the machine 'frame and has its other arm formed as a segmental gear 371, as shown. This gear meshes with a segmental gear 360,
formed on one arm of a lever 36, which is also fulcrumed to t-he frame of the machine. rllhe other arm of the lever is formed as a segment 361, having notches therein to receive a tooth 27 which is carried by a short lever 27a, pivoted to the short arm of the lever 210, and connected at its free end by a rod 27" to a pawl-controller 211, which is pivoted to the long arm of the lever 210 near the end thereof. rlhe lever 210 is fulcrumed to the same shaft as the lever 36, andhas a pawl 26 which engages the teeth of a rack 260, supported from t-he frame. This pawl is connected by a rod with the controller 211 upon the opposite side of the pivot from the point of connection of the rod 27" with the controller. The lever 210 may beset at a convenient height for operation by placing the tooth 27 in the desired not-ch in segment 361. rlhe lever 210 is manually releasable from its rack by withdrawing the pawl rack 260.
26 from the rack 260, and may be depressed to effect rearward movement of the rods 178, 178a and 178", which will thereby cause the cams A22, 22a and 22"- to rock the bell- cranks 176, 176a and 176", and project the rods 171 forward, compressing the springs 172 and closing the pincer jaws. A continued downward movement of the lever 210 will, by exerting further strain on the rod 178, move the three pincers and the entire pincer-carrying frame bodily in a direction to stretch the upper, and the lever will be retained in position with the upper held under tension by the engagement of the pawl 26 with the A balance spring 101 extends from the lever 210 to the fulcrum of the bellcrank 122, or other fixed point, and assists in holding the pawl 26 in engagement with the rack when an upper is under tension.
The pincer rod 35 extends rearward-ly and is externally threaded to engage the internal threads of a` nut 236, carried rigidly by a sleeve 34 to the opposite end of which is secured a pinion 45. The sleeve is rotarily supported in a tubular bearing 34a carried rigidly by a box or casing 33. The casing 33 is supported, with capacity for sliding` mesh with a pinion 139. This pinion is fast to a shaft that turns in bearings in the frame and has a hand-lever 340 by which the pinion may be turned for raising or lowering the casing 33 carrying the pincers. These adjustments provide for moving the three pincers simultaneously to locate the pincers in proper position for operation upon shoes of dilferent lengths.
A segmental rack 44 meshes with the pinion 45, and is provided with a rigid arm 45a which is pivoted` at 45" to a lugextending from the box or casing 33. The rack 44 is reciprocated by a'lever 43, fulcrumed at 84 to the frame head, and connected by a link 85 to the rack. T he handle end of this lever extends toward the front of the machine and is in position for 'convenient manipulation by the operator. After the. lever 210 has been depressed to cause the pincers to seize the upper and to strain itprelimina-rily to the last, a further pulling of the upper may be e'ected by depressing the lever 43 which causes the rack 44 to rotate the pinion 45,
sleeve 34, and nut 236, thereby moving the pincer rod 35 Y rearwardly and applying through the springs 136 a yielding strain to the upper. A. lever 46, fulcrumed at 45" to the casing 33, has its forwardly-extending arm connected by a lilik with a latch 47, which is pivoted to the casing and has near one end a shoulder to,Y engage the forward edge of the plate 141 and has also a tooth oppositely directed with respect to said shoulder to engage the wall of a recess in the plate. rlhe rearwardly-extending arm of the lever 46 is connected with the larm 45a of the rack ,44 through a spring 86 So as to be raised to lift the latch 47 out of engagement with the plate 141 when the rack is moved upwardly to impart the final upperstrainingv movement to the pincers. 'llhe construction and arrangement of the Vdescribed parts are such that during the first portion of the upward movement of the rack the nut 236 will be rotated and thus impart a final pull to the pincers while the latch 47 holds the casing 33 against movement in feit-her direction, and the spring 86 will yield and thus delay the tripping of the latch. Upon a continuation of the upward movement of the rack, however, the spring will be compressed sufiiciently to trip the latch, thus releasing the frame 33 so that the frame and pincers will be free to move rearwardly and away from the shoe when the pincers have been opened torelease their grip upon the upper, 'as will be more fully explained hereinafter.
Just before the pincers release their grip upon the pulled upper an upper-pressing `pad 90 is, through power-operated instrui shoe. The arm 91 is'pivoted to a rigid part of the frame, and a link 89 and sliding rod 89a connect the arm with a cam roll 92 that run's in a cam groove in the upper face of a cam 196, which is supported forrotation in bearings on the frame head. The cam has a geared connection with a gear 94, the ratio of these gears being one to one. The gear 94 is fast to a shaft 95, rotating in bearings carried by the frame, and havin securedto its lower end a gear-96 w ich meshes with and is driven by a gear 97, havc ing the same number of teeth as the gear 96, and which is secured to the shaft 110 heretofore referred to.
The shoe materials about the toe end of the -lastare held in position, following the pulling-over operation, by a toe clasp, which is power-operated, and the pulled upper is secured to the last by, tacks that are driven through the upper materials and the margin of the innersole while the upper is being held to the `end portion of the last by the toe clasp. y
Referring more particularly to Figs. 1, and 4 to 7, inclusive, an arm 42, rigid with the frame head B, projects downwardly' therefrom substantially in line with the shoe when the shoe is supported in position to be pulled-over. This arm has a guideway therein which receives the sliding carrier 41 to which are pivoted at 182 two outwardly curved arms 50, whose. outer ends are connected with the end portions of the toe clasp 40. The toe clasp, as herein shown, is composed of-a flexible band of sheet steel, or other suitable material, provided with a felt, rubber, or other soft lining having V- shaped projections or teeth 40El that will readily conform to the curvature of the toe.-
end portion of a last and engage the upper leather .frictionally in a manner to vfirmly -pressit about the end of the last, but with- Yout injuring or marring its surface.
The hubs of the arms 50 are provided with inwardly projecting lugs 183 which engage a spring-pressed plunger 184, sliding in a recess at the'lower end of the carrier 41, and which acts .to yieldingly force the arms 50 outward and thereby hold the clasp in open or extended condition. When lthe clasp is forced against the toe, end of a shoe the pressure on the center of the clasp will draw the outer ends of the arms 50 inward, thereby forcing the plunger 184 into its recessY and compressing the spring 184a so that the clasp will be Wrapped about the toe of the shoe against a yielding resistance.
The toe tackers are supported from a carrier* member 41a that is movably connected with the toe-clasp carrier 41 by a rod 185 the lower end of which is secured to the bottom of a recess in the carrier 41, and the upper end is threaded and passes through a perforation in a lug extending from the car- The tack drivers 186, 186 andl 189 for-- driving the tacks at the end of the toe and upon opposite sides of the shoe near the toe end, are carried by rods mounted for sliding movements in tubular extensions of the frames 187, and spiral springs 1863, 186g, 189, confined lbetween heads on the rods and the tubular bearings, return the drivers to raised position following Ieach tack-driving operation. The base of each tacker frame is rounded o' slightly at its lower front edge 187X for pressing the margin of the upper snugly into the angle formed by the lip and feather edge of an innersole for a welt shoe,
\ and a flange 187 Y extends angularly from the lower face of the tacker base, to the rear of its rounded edge, and serves to press the upper firmly against the outer edge of the innersole.4 j
The fore-part tackers are provided with tack pockets 80 .arranged with forwardlyinclined front walls and mounted upon slides 82 that have driver openings 83 therethrough, and are operated by springs 83a. The tacks are supplied to the tack pockets 8O from a hopper 400 through tubes 401, the hopper being provided with any appropriate tack-feeding mechanism, such for example as that disclosed' in U. S. Letters Patent No. 668,777, dated December 11, 1900, which automatically feeds a tack to each tube for delivery to its tack pocket when the tackers are in tack-receiving position, as shown in Figs. 4 and 5. ln the illustrated embodiment of the invention, there are two tack drivers and two tack tubes `for each side ,tacker, .and a single tack driver and tack `\the sides of the shoe, as shown in Fig. 7.-
@he support for the toe end tacker has a forwardly extending cam member 55 provided with an angularslot which receives a pin 54 projecting rigidly from the side ot the arm 42, the shape of the slot being such as to cause the tackei's to move from the position shown in Fig. 4 to that shown in Fig. 7 when the carrier 41 is depressed, and to return the tackers to the former of these positions when the carrier is raised.
The side tackers are rigidly sustained upon rods 183l whose inner ends are fast to the movable leaves of the hinges 191, connecting the side tackers with the toe end tacker. Sleeves 58, surrounding the rods 18S and rotatable thereon, are provided with lugs which are pivotally connected with links 59, the links being in turn connected by universal joints with a cross bar 57 that extends through and is guided in slots in the, sides of the carrier 41, and is pivoted to a rod 60. A spiral spring 192, which is stiffer than the spring 185 heretofore described, is located below the cross barili a recess in the carrier 41a and acts to yieldingly transmit downward movement from the rod 6() to the carrier members 41 and 41.
The rod 60, preferablyv made in two parts connected by an adjustable turn-buckle G0", is pivotally connected at its upper end to one arm of a lever 193, which is fulcrunied to the frame head `and has its other arm loosely connected to a rod 194 which reciprocates in a guide block `195. This rod carries a cam ioll 51a that engages a cam groove 51 in the cam 196. A. link 198 connects the rod with a plate 200, pivoted to the same shaft as the toothed lever 36 and having a cam face which engages the tooth-27 and is arranged to force it out of locking engagement with the toothed segment 361 when the link is raised. The link is made in two parts connectedby a turnbuckle 202, through release, toe clasp elo ing, and fore part iacker actuating mechanism may be adjusted.
The tore-part tack drivers aie actuated by a lever 72 which is ulcrumed to a pin 72a'ou an extension of the member 41a, and has a driver spring 73 coiled about the fulcruin pin, and with its free end bearing against another pin on the long arm of the which the timing of \the automatic pincer lever. rllhe lever-72 has a head 72b, of suf-` ficient area to engage simultaneously the ends of the three driver rods when the saine are grouped in driving position as shown in Fig. 7, and the short arm TS of the lever has connection with one end of a lilik T4 whose other end has a slot T5 which slides along a pin fixed to the frame head.
The carrier member 41a supports a sliding spring-pressed latch 71 having a beveled end, and the driver-lever is provided with an abutment 10 having a surface ,which engages tlie lower face of the latch and retains the lever in position for driving. and a rounded or beveled face below the engaging surface for pushing the latch rearwardly when the lever is being set, or put in condition for action. The rod 60 passes through an aperture in the latch, and carries a wedge 7() which is threaded to the rod for adjust inentand is adapted to engage a beveled rear wall of the aperture to cause withdrawal of the latch lfor tripping the driver lever whenthe rod is depressed.
The cam groove 51 comprises a straight portion which is occupied Yby the cam roll when the parts are as shown in Fig. 1, and a raised portion into which the roll passes to effect the automatic pincer release and also the depression of the toe clasp and the toe tackers.
In the use of the machine, the usual shoe materials, including an upper, lining. counter-stiffener and innersole, are placed loosely upon a last, and with the arm 7 turned down into the position as shown in Fig. 3, the shoe is placed in. the position shown with the spindle 1 in the jack pin hole ot' the last and the rest 130 engaging the shoe bottom. The operator then assembles the several shoe parts on the last in the positions that they are to assume in the finished shoe. The arm 7 and parts carried thereby, including the pin 1 aiid sole rest 130 with the shoe clamped therebetween, the block Z and supported parts, are then swung about the pivot 3, from the position shown in Fig. 3 to that shown in Fig. 1, the pin 9 also swinging around pivot 3, and in doing so it is located near the right hand end of slot 8a. In this mov ment the cam roll 501l moves from the high 5 o the low part 'of the cam that as he stands in a normal attitude in front of the machine the operator magy7 have a full View of the top ofthe shoe, and can readily observe if the lines of the upper are in proper relation tothe lines of the pulleyvto the shaft 99, which makes one complete rotation and stops. Prior to starting the machine, the cam roll X rested upon the low part of the cam 118, and the bellcrank 122 and link 8 were held in a forward position. The complete rotation of shaft 99 e'ects but one-third of a rotation of the shaft 110 and of shaft 116 with its cam, the high point of which willmeet the roll X and'elevate rod 120, thereby swinging the long arm of bell-crank 122 and the link 8 rearwardly until'the end of slot 8a engages the p in 9 and pulls the bar 11 in the' same direction, which moves pawls 15 until their ends engage and lift the drivers 13, 14 thereby putting the spring 13El under tension. Continued movementJ of the pawls will cause their rear ends to engage the pins d, and trip the drivers which will then drive the two assembling tacks into the shoe materials at the heel end ofthe last. Before the described machine parts are brought to rest the cam 118 will rotate sufficiently to permit the roll X to pass again onto vthe low part of the cam, thus permitting` the spring 122a to move the bell crank 122 and bar 8 forwardly until the slot 8a is in suchv position that the pin 9.will engage the lefthand end of the slot, so as to shift the bar 11 to its inner position when the jack is again swung into` the position shown in Fig. 3. -While the mechanism for driving the assembling tacks is operating, one-third of a rotation will be imparted to the cam 196, but as the roll 51a occupies the straight, or low portion of the groove 51 at this time the lever 193 carrying the toe clasp and fore v part tackers will not be moved from its elevated position, as shown in Fig. 1.
rlhe assembling operation having been completed, the operator inserts the margin of the upper, at the end of the toe and on both sides of the fore-part, between the open jaws of the pincers. He then depresses the lever 210', which closes the pincer jaws upon the upper, and a continued depression of the lever ywill move the rod 35 and the boX or casing 33 rearwardly until latch 47 engages the plate 141, such movement transmitting to the pincers an updraw. rll `he pincers may then be retained in position to hold the upper under tension by the engagement of the pawl 26 with the rack 160. Opportunity is now afforded the operator for further inspection of the shoe and, if
he fn'ds that the upper has not been pulled properly with respect to the lines of the last, by releasing the lever and slightly raising its forward end the pincer jaws will be opened and the upper may be adjusted properly therein, and the lever again ,depressed to close the jaws andlupdraw the tackers to move into position.
casing 33, and pincers connected therewith,
free to move rearwardly and away from the shoe a sufficient distance to permit the While the pincers retain their hold on the upper, however, the tension of the strained upper prevents the pincers from moving away from the shoe.
The operator then steps on the treadle again and rotation is imparted to the power shaftfwhich effects movement of the cam 196 a further distance and suliicient to cause the cam roll 51a to enter the high part of the groove 51 and raise the rod 194 far enough to depress the toe-end clasp and wrap it about the toe end of the shoe, and also to move the pad 90 in position against the upper part of the shoe, rearward of the toe. The same movement of the rod 194 causes cam 200 to force tooth 27 out ofthe segment 361, thereby releasing the lever 37, and per-y mitting the spring N to move the rods 178, 178a and 178b forward, the ends of slots 181 then engaging the pins connected with the pincer-closing cams and turning these cams in a direction to permit the springs 172 to open the pincer jaws. The pincers will then be forcibly carried by the springs 136 away from the shoe until the ends of the slots 240 engage the pins 241, and the momentum thus imparted to the pincer System will carry Athe rod 35 and casing 33, and its attached parts, including the pincers rearward far enough to leave ample space between the pincers and the shoe for the accommodation of the forepart tackers. The machine will :then be brought to rest a secondv time by the one- :revolution clutch, the 'cam roll 51hI having progressed part way along theihigh part of the cam groove.
The operator than steps on the starting treadle a third time, andV further rotation of the cam 196 is effected to cause the roll to enter the final portion of the high part of the cam groove, thus depressing the rod 60 a furtherdistance, This movement folds the side tackers about the sides of the fore-part of the shoe and turns the side and end tackers in upon the sole, the corners 187X of the tackers smoothing out any wrinkles in the upper andpressing it snugly into' the angle between the feather edge and lip of the innersole, and the flange 187y assembling and pulling-over the shoe, and
the machine is thereafter brought to rest. Before the movement of the power shaft stops, however, the upper cam groove in the cam 196 raises the arm 91 and removes the pad 90 from the top of the shoe, and the cam roll 51 passes into the low portion of the groove 51, thus effecting upward movement of the toe clasp and the toe-end tackers, and restoring these parts to the positions formerly occupied by them and where they will be in readiness for operation upon another shoe. 200 is restored to its original position, permitting the tooth 27 to rengage the toothed segment 361 and to lock the lever 210 to the lever 36, thus restablishing an operative connection between the pincers and their closing and pulling lever. The lever 210 will next be manipulated to move the pincers and the supporting casing 33 toward their initial position, and the lever L13 will then be raised for moving forward the pincer rod 35 carrying the pincers, and for depressing the latch 47 into position to coperate with the plate 141 in the manner hereinbefore described when another shoe is operated upon. The operator then swings the shoe support into the position shown in lig. 3 which unclasps the heel band from the counter, the shoe is removed, and the machine is in readiness for another operation.
