To all whom it may concern:

Be it known that ORRELL ASHTON, late of Swampscott, in the county of Essex and State of Massachusetts, deceased, invented certain Improvements in Assembling-Machines, of which the following description,

in connection with the accom anying draw-1 ings, is a specification, like re erence characters onthe drawings indicating like parts in the several figures.

This invention relates to machines for assembling parts of boots and shoes upon their lasts preliminary to the pulling-over and lasting operations. For the purpose of illustration an embodiment of the invention has been selected and is shown herein as applied to a machine of the type described 1n Letters Patent of the United States, No. 1,204,928, granted November 14, 1916, upon an application of Orrell Ashton.

It is'to be understood, however, invention is'not restricted to embodiment in a machine of the particular type disclosed in said atent. In the earlier machine above referre to the-upper is held to the last at a point adjacent to the heel seat and the upper is wiped downwardly or toward the narrow top part or cone of theinverted last as well as over the heel seat of the last, two tacks being then partially driven into -the\rearend face of the shoe and a single tack completely driven into the end of the heel seat of the last through the upper material in end face of the cone of the last and then tensioning the uppertoward and over the heel seat of the last and there securing the upper materials including the counter to the heel seat; Preferably the u per is also secured to the rear end face 0 the heel seatat a point near the heel seat.

A feature of the invention consists, there-, i ore, in means for holding the upper materials against the rear end face of the last at a point remote from the last bottom, means of the cone that the gripping surfaces Specification 011.6%! 2mm. 'r t t 'o t, 2 9 Application filed April 17, 1618. Serial 110. 91,672.

for tensioning the-portion of upper 1 ing and preferably to the heel seat of the last. In the construction shown herein the last is bottom up and the upper is held clamped unyleldingly at a point adjacent to the top part of the last between the last which is pressed inwardly-and a block, referably V'-shaped, which is held in fixed position. This clamping means may be reliedupon to hold the upper at this point from upward movement relatively to'the last, Tacking means, however, isprovided for o tional use which will insert a tack, preferab y through V to the last, the block being arranged by verthe V-block, additionally to secure the upper v through the upper and counter near the edge of the counter which lies nearest the cone of the last. The upper while held at this pressure of the last against the point, by

also by the tack if desired, is tenblock and sioned upwardly by the tensioning means which, as shown herein, comprises the forward end of thewiper and a cooperating gripper member which is actuated to grip the upper'between it and the end of the wiper. The wiper is operated in a direction to wipe theupper over upon the heel seat, at the same time acting to tension the upper throughout substantially the full width of thevamp in an upward direction from a point near the top of the cone of the last where it is held bythe clamping pressure as described and if desired also by the tack already driven at'that point. As the wiper advances the upper, preferably, is gradually withdrawn from between the cooperating of the wiper and gripper member and is laid under tension upon the heel seat, means being provided for securing the upper materials including the counter thus treated to the heel seat. This means as shown comprises tacking mechanism which acts preferably through the wiper to insert a tack at the rear end of the heel seat through the overlaid margin of the'counter," and to clench itupon the heel plate of the last.

lining and innersole V-block and acts to center The means for clamping the upper 11nyieldingly against the cone of the last may comprise, as shown, a last support WhlCh forces the last rearwardly against the fixed lower V-block and holds the upper clamped at this point during the upward tensioning of the upper. Preferably also, the last support is held against downward movement during the overwiping movement of the wiper.

It is important that the shoe support, during the positioning movement of the shoe relatively to the upper tensioning means, he movable vertically to facilitate insertion of the upwardly extending margin of the upper between the gripping members. A feature of the invention, therefore, consists in the combination with tensioning means to which the upper is presented by upward movement of the shoe, of means for supporting the last for depression by light downward pressure ands adapted when the last is released to raise the last and bring the upper into position between the gripping members and the tensioning means.

Another feature of the invention consists in the combination with means for holding the upper unyieldingly at the rear of the last near the cone of the last, and means for tensioning the upper upwardly from the point held, of means for pressing yieldingly against the rear end face of the last at a point adjacent to the heel seat; Means is also provided which may be used when desired for securing the upper to the last at this point by a partially driven tack. As shown, the yielding pressing means comprises a second block which is preferably a the last by engagement of its inclined faces with the curved rear face of the last. This block is mounted for yielding movement rearwardly in a substantially horizontal direction, being preferably held forward by a spring in a position in advance of the lower V- block so as to engage the shoe first as the shoe is moved toward the machine and to press the shoe parts into assembled rela-' tion on the last. As shown tacking mechanism is provided which may or may not be used at the option of the operator to insert a tack preferably through the block and into the-rear end face of the shoe at one side of the back seam and near the plane of the heel seat.

In lasting the sides of shoes the side laster is required to see that the ends or wings of the counter stiffener are properly -drawn up at the shank of the shoe and secured to the tread face of the shank of the sole. Under some-conditions, particularly where molded counters are used, it is also demanded of the side laster that he secure to the heel seat the flange of the counter which extends over the heel seatwhich at the rear of the shoe by tacks driven not through the upper but through the counter flange and into the heel seat at each side of the tack driven by the assembling machine through the upper and counter flange at the rear portion of the heel seat adjacent to its longitudinal median line. Since the rear portion of the upper is held by this central tack in a position bent over the rear portion of the counter it is only with some difficulty that the laster can insert tacks at each side of the central tack through the flange of the stifi'ener only and this requirement. reduces his production.

An important feature of this invention consists in means for insertingtacks through the flange of the counter-or heel stiffener automatically and as a part of the assembling operation. By this means tacks are driven near the rear end of the heel seat through the flange of the counter stiffener and into the heel seat. As shown herein the flange tack driving mechanisms operate substantially simultaneously with the means for driving the central tack at the rear end of the heel seat and are located ads jacent to what are known as the corners of the heel seat, that is, near the points where the curvature of the rear end of the heel seat merges into the curvature at the side of the heel seat. These flange tacks, therefore, are located at each side of the central tack at the end of the heel seat and somewhat in advance of it or nearer the toe of the shoe. The central tack at the end of the heel seat, herein termed the through the upper as well as through the counter lining and innersole, and the tacks in advance of it, termed herein the flange tacks, are not driven through the upper but through the flange of the counter stiffener, lining and innersole only, all of these tacks being clenched upon the heel seat plate of the last. Preferably two flange tacks are driven, one. at each side of the heel seat tack and in laterally and forwardly spaced relation from it.

heel seat tack, is driven.

Another feature of the invention consists tively the counter, upper, and last.' The counter pressing means may include pressers hold in the counter at the wings of the counter and preferably and as shown the corner and wing pressers are so connected to their operating means that the pressure is distributed between them and preferably seen that the lipper and lining and innersole assembled thereon, inserts acounter, for example, amolded counter between the upper and lining, and places the last upon the spindle 20. He then depresses the spindle against the spring 18 and swings it toward-the machine. Having swung the shoe inwardly as far as it will go, he releases it and allows the post 16 to rise under the impulse of spring 18. This movement brings the upper at the rear of the shoe into the position shown in Fig. 7, the upwardly extending margin of the upper then lying between the nose of a wiper and a gri per member 72 having a gripping face of a curvature corresponding to that of the nose of the wiper and adapted when operated to hold the upper against the nose of the wiper as illustrated in Fig. 8. When the work has been positioned as described the operator depresses a treadle 76, Fig. 1, which acts through a rod 78, Fig. 2, upon a controlling mechanism 79 to connect the shaft 6 with the power driven pulley 80. The controlling mechanism 79 may be of any usual type but as herein shown is substantially similar to that disclosed in United States Letters Patent No. 1,026,067, granted May 14, 1912, on application of Orrell Ashton. As the cam shaft 6 begins to rotate, the projection on the cam 42 passes beyond the roll 40 and permits the spring 44 forcibly to depress the hook 30 which acts upon the roll 50 to draw the jack and shoe inwardly toward the machine and lock it inwardly and against depression as described. As the shoe is drawn in toward the machine it first contacts with an upper V-block 86, Fig. 8. This block is mounted on a horizontal slide to yield inwardlyagainst a spring 88, Fig. 1, and by yielding allows the shoe to come into engagement with a lower V-block 90 which isheld in fixed position. The shoe is now held with the upper and counter firmly pressed against the rear end face of the last, the upper being held unyieldingly near the cone of the last at each side of the back seam by pressure of the last against the V-block 90 due to the action of the cam face of the hook 30 upon the last support and being held yieldingly near the heel seat by pressure of the V-block 86. The upwardly projecting portion of the upper has been seized between the nose 70 and the gripper 72 by mechanism actuated simultaneously' with the downwa-rd movement of the hook 30 in the following manner.

Referring to Figs. 3, 4 and 6, it will be the hook 30 when in its normal position with the machine stopped engages a roll 100 on the end of a lever 102 which is pivoted at 104 to a bracket 105 mounted on the base 2. The lever v102 has a projection on its upper face which enga es an arm 106 fixed to a rock shaft 108 aving 150 are pivoted. for limited also a longer arm 110. The rock shaft 108 tends to rotate in a direction to depres the outer ends of the arms 106,110 b reason of a spring 111, Fi 3, coiled a out the shaft 108, one end 0 which engages a lug 113 on the bracket105, the other end of the spring being secured to a collar 115 which is held to the shaft 108 by means of a ratchet and pawl mechanism which affords means for adjusting the tensionnof the spring 111. A pull rod 112 passes through a trunnion 114 journaled in the outer end of the arm 110and is connected at its upper end to one arm 116 of a bellcrank lever, the other arm 118 of which is connected b a link 120to a rod 122 one end of which is rigidly secured to the gripper 72 below its pivot 124. The rod 112 carries below the trunnion 114, an adjustably fixed collar 126, and above the trunnion a sliding collar 128 which is backed by a light spring 130 held by its upper end to a fixed collar 132. Referring now particularly to Fig. 6, it will be seen that when the hook 30 is depressed as described the pressure of the projection on the lever 102 against the arm 106 will be released, permitting the spring 111 to act upon the rock. shaft 108 and depress the outer end of the arm 110. This arm acting upon the collar 126 moves downwardly the rod 112 and through the bell-crank lever .116, 118 pul1s upon the link 120 to force the gripper member 72 into position to hold the upper be tween its lower end and the nose 70 of the wiper. When the arm 110 is again raised at the end of the cycle of the machine the spring 130 will yield if necessary points prevents the counterfrom bulging or drawing away from the last. This mechanism is actuated simultaneously with the operation of the gripper 72and comprises mechanism best shown in Fig. 3. clamping members 150 are located one upon each side of the shoe and each carries two

upper clamping projections

152, 154 which are inclined upwardly and inwardly to- Ward the shoe and engage the sides of the shoe in substantiall the planeof the heel seat as shown-in ig. 14, the projections 154 engaging the sh e at the corners of the heel seat and the projections 152 pressing in the wings of the counter. The members 156 to arms 158' which .are

T e presser operating means is automatic in action and comes into operation when the machinestarts-to press in the counter at the opgosite sides of the shoe at the corners an wings of the counter before the flange tacks are driven. x

These and other features of the invention will appear more full from the followin' description when rea in-connection wit the accompanying drawin and will pointed out in the amends .claims.

Referring to "Fig. 1 of the drawing, the

numeral 2 indicates the base or column of the machine and 4 the frame of the head of the machine upon which various operating parts of the machine are mounted and are operated by cams or other mechanism con- 7 nected with the main shaft 6. A jack memher 8 is pivoted at 9 tothe frame of the machine and has its outward movement limited by a rod 10 carrying a bufier-sprin 12. A red 14 telesco es into the lower en 16, t e jack post 16 being supported upon the rod 14 by a spring 18. The. rod'14 is reduced at its lower end to e age a hole in a piece 15 which is adjustal fy held in the member 8 by a set screw 17. In the upper-end of the post 16 a last in 20. is fitted which may be adjusted vertica y relatively. to the post 16 by lifting and rotat of a jack post igs. 4 and 5 are sectional details of a ing the pin to cause a proje'etion 22 to engage in one of a series of vertically spaced,-

notches 24 formed around theperiphe of the upper end-of the hollow post 16. lhe stren h of the 5 ring is such that the post may depresse by the operator, its movement being suitably limited by a pin and slot connection between the parts 14 16 at 19 and mechanism is provided for forcing and holdin the 0st in toward the machine and for 100 g t against depression while the machine is inoperation. This mechamsm comprises a hook 30 pivoted at 32 to the machine frame and arranged tov be operated by a rod 34 which connects a rearward .-.extens1on of the hook 30 with a bell-crank acted upon by a cam 42 fixed upon the shaft 6. p The action of the cam upon the cam roll 40 raises the hook into the osition shown against a stiif spring 44 coiled about the axis 32 and arranged forcibly to depress the hook 30 when the rojection on the cam 42 moves off the roll When the post is swung-toward the machine about the pivot 9, a roll 50' mounted on the member 8 is brought into position to be engaged by the hook 30 when it is de ressed, as described, the hook thereby locking the shoe support inwardly toward the machine during its operation. The face of the hook 30 which engagesthe roll 50 is not concentric with the pivot 32 but is cam-shaped to force the roll and support inwardly as the hook is moved downwardly.

The hook 30 also effects a locking of the post 16 against depression, as shown in Fig. 5. The post 16 has formed upon it a series .of ratchet teeth 52 and passes loosely through an opening 53 in 'a'member 54 which is pivoted at 56 to the member 8. The member 54 carries a locking pawl 58 which is arranged to enga e the teeth 52 when the member 54 is move to the left in Fig. 5 by the action of the hook 30 upon the roll 50 provided the. 0st 16 is prevented from moving inwar 1y by reason of contact of the work with. arts of the machine. When movement 0 the post 16 toward the machine is thus prevented the lower part of the member 54 where the post passes through the hole 53, ,is, of course, prevented from moving inwardly and the member 54, being held at 53, swings about the pivot 56 causing a rojection 60 upon the member 54 to ress ownwardly upon a spring plunger 62.

hismovement allows the pawl 58 to come in contact with the ratchet teeth 52 and to lock the post 16 against depression. When .the hook 30 is raised the spring plunger 62 acts to release the locking pawl from the ratchet teeth and the post 16 is free to move vertically.

The ma s afts 160 extend'downwardly and carry at their lower ends-inwardly projecting arms 164. Coiled torsion springs 166 are connected between the,'bracket 105 and fixed collars 167 on the rock shafts 160 so as to cause the arms 158 to move toward each other thereby bringmg-the projections 152, 154-on the levers of the shoe.

work simultaneously with the operation of the ipper member'72 to seize the upper.

T e upper is now correctly positioned and held for the insertion of the first fastening which is inserted through the lower V-block 90, as shown-in Fig. 8. The tack for the block 90 is en plied by a tack separator located at 170, i 1, and passes through a driver passage in the block 90 in front of a driver. mounted on a driver bar 174 which is actuated by alever 176 piv-' oted at 178 and having a projection 180 scribed in .thepatent construction in detail.-

which engages a cam 182 on the main shaft. The drop of the cam is so arranged as to actuate this driver by its driver spring mounted upon the shaft 178 prior to the actuation of the other tack drivers. and prior to the forward reciprocation of the wiper which next takes place. f

The wiper 70 is mounted and operated in a manner substantiall as is shown and dest referred to above. It is therefore not necessa' to describe this hewiper 70 'is moved forwardlyover and along the meear upon the shoe and a hen the machine is in stopped by the action of the.

gripper member 72 holds the upper against the end of the wiper 70 and cooperates therewith.to tension upwardly at the rear of the shoe the portion of the upper which. extends above the tack alread driven through the block 90. At this point the upper is held by said tack and by the pressure of the shoe against the rigidly held block 90 While the upper block 86 is held ieldingly against the upper and permits the upper to draw upwardly beneath it as the wiper and gripper member advance to tension the upper over the shoe bottom. uring this move- -ment the portion of tween the nose of the wiper and the gripper member is gradually withdrawn from engagement between them. While held'under tension by the frictional engagement of these members, however, it is laid down upon the shoe bottom and is held in that position by pressure of the wiper on the shoe bottom until it is secured by a tack driven through the upper held be-i the wiper 7 O and into and through the .overlaid upper, counter, lining and innersole and clenched upon the heel plate of the last, as is clearly shown in Fig. 9.

The wiper 7 0 moves a predetermined distance over the shoe bottom and hence the heel seat tack is driven at a predetermined distance .from the rear edge of the bottom of a shoe positioned by the block 90. This distance may be varied by turning the hand wheel 85, the construction for efiecting this adjustment being substantially the same as that shown and described in the prior patent first referred to above. I

The wiper 70 is let into the upper facev of the block 86 by a groove 71, Fig. 3. This construction permits the upper block 86 and its tacking mechanism to be adjusted near to the plane of the heel seat.

Substantially simultaneously with the insertion of the tack in the heel seat, as just described a tack is inserted through the upper V-block 86 into the rear end face of the last at a point at one side of the back seam and adjacent to the plane of the heel seat, as is also clearly shown in Fig. 9. This tack and the lower tack previously driven are preferably left with their heads upstanding from the surface of the upper to facilitate their subsequent Withdrawal. The upper rear tack is supplied by the separating mechanism 170 to the block 86 through a tube 190 and is driven bya driver attached to the forward end of a driver bar 192 which is actuated by a lever 194. The lever 194 is moved to the left in Fig. 1 to tension a suitable driver spring located on the shaft 178 by the action of a cam'196 upon an inward projection 195, Fig. 15, of the lever 194.

' is still held in that The cam 196 has its drop so located as to permit 0pc ration of the driver bar 192 at a point later in the cycle of the machine than the cam 182 permits operation of the driver bar 174. I

For driving the rear heel seat tack a lever 200 is pivoted at 202 to the carrier which advances. the wiper over the shoe bottom and is raised to tension the driver spring by the action of a cam 204 located behind the cam 42 in Fig. 1 which acts upon a roll 206 on the lever 200 to raise a driver bar 208. The driver bar 208 is released to drive the heel seat tack, as shown in Fig. 9, substan tially simultaneously with or slightly later than the release of the driver bar 192 drive the upper rear tack, also shown in that figure. The rear heel seat tack is supplied to the wiper 70 by the separating mechanism 170 through a tube 210, Fig. 2, and drops into a tack retaining means in the wiper 70 into position beneath the driver on the bar 208, as shown in Fig. 7. The tack retaining means in the wiper 70 has the construction shown in Figs. 10, and 11, and comprises a member 212 having a funnelshaped slot 214 open on the inner side and having its wide end located beneath a passage in the wiper 70 leading from the opening of the tube 210 to permit a tack to drop into it. The member 212 has an outwardly extending stem 216 which passes through a member 220 and is retained by a pin 222. A spring 224 is located in a socket in the member 220 and acts to press the member 212 inwardly into tack retaining position but is adapted to yield upon-descent of the driver to permit the tack to be driven past the member 212 and into the work. The member 220 is formed, as best shown in Fig. 10, with a flange 226 which engages grooves 227 in a wiper member 70 'to retain the member 220 in position.- The flange 226 is cut away on opposite sides so that by giving the member 220 a quarter turn it may be removed from the wiper member 70 for inspection and clearance of the tack passage in case it should become clogged. To insure exact lo-' cation of the member 212 with the tack passages in the member 70 a locating pin 228 is provided which engages a hole/230 in the member 70 when the member 212 is placed in operative position.

echanism is provided for inserting a plurality of tacks through the flange of the counter adjacent to the corners ofthe heel seat as is clearly shown in Fig. 16. These tacks plreferably and as shown do not pass throug the upper but through. the counter, lining and innersole only to secure the counter in against the rear portion of and serve firmly the last while it position by the pressure of the upper V-bIock 86, by the counter corner and

described the tack proper position and by the wiper 70. These flan e tacks are supplled by the separating mechanism 170 each of the guides 254,256 is provided a tack pocket for holding the tack in position until it is driven comprising two members 258, 259 which are pivoted together by links 260 to permit separation of their tack holding ends and are normally held closed bya spring 262. Between the members 258, 259 is provided a slot 264 and by separating the tack holding ends or jaws of the members 258, 259 these members may be placed in position to be retained upon the lower ends of either of the driver guides 156, 154 which are each formed, as shown, at the right in Fig. 12. When the members 258, 259 are allowed to close, the slot 254 embraces, for instance, the portion 266 of the driver guide 254 and the jaw mem-,

bers are held from downward movement by a flange 268. When thus positioned the tack pocket 270 formed in the inner ends of the members 258, 259 is in alinement with the driver passage 272 in the driver guide 256. The tack pocket 270 has a form half of which is illustrated in Fig. 13 which is adapted to hold a tack in position beneath the driver until its descent whereupon the two portions of the. tack pocket yield laterally to permit the passage of the driver through the pocket for the insertion of the tack into the work. It will be observed that by the construction pockets are readily removable when necessary and for convenience in initially separating the members 258, 259

the forward inner edges of the members are plete removal of them from the driver guide.

The flange tacks'are driven by

drivers

276, 278 which are connected, as shown in Fig. 2, withma head 280 fixed upon the upper end of the driver bar 208 by which the central heel seat tack is driven. By this construction, therefore, the flange tacks are driven simultaneously with the central tack and by the same driver spring. It will be seen that, as shown in Fig. 1, the counter driver ides and drivers are located somewhat in afvhnce of the central heel seat tack so that they pass beyond the portion of the margin of the upper which is laid over the heel seat by the wiper 70 and insert their tacks through the flange of the counter adjacent to the corners of the heel seat and beyond the margin of the upper. The position of the counter tacks is clearly illustrated in Fig. 16. This figure shows also the position of the three other tacks which are driven through the assembled upper.

. that a The counter tack driver uides are arranged for adjustment latera ly of the shoe to position the tacks at different points laterally of the flange of either wide or narrow shoes. guides 254, 256, Fig. 3, are supported on slotted brackets 255 by screws 257 which'pass through the slots in the brackets and into the guides. By loosening the screws 257 the guides may .be adjusted in the direction of the slots'laterally of the heel seat.
