I MACE-ZINE FGR 'WORKING UPIEPt-S OVER LASTS.

Application filed September 25, 191.9. fierial No. 326,175.

v The ii vention relates to machines for workin uppers over lasts in the manufacture of boots and shoes, and in many of its aspects has reference more particularly to machines for pulling uppers over lasts.

A feature of the invention consists in a novel organization of means for controlling the application of pressure in the operation of laying the margin of an upper inwardly over the sole or insole of a shoe. In one of its aspects the invention has in view an organization wherein the shoe receives a comparatively light overlaying pressure in the inward movement of the overlayingmeans or in the first portion of such movement, and wherein the pressure is increased by relative movement of the shoe and the overlaying means while said means is positioned over the bottom of the shoe. One important advantage of such an organization is to be recognized in operation upon shoes having comparatively flexible or yielding insoles such, for example, as the type of shoe herein illustrated, commonly known as an arctic shoe, in which the insole comprises a composition of unvulcanized rubber. By moving the overlaying means inwardly across the outer edge of the insole of such a shoe with light overlaying pressure insurance is af forded that the margin of the insole will not be pressed back from the edge of the last bottom or otherwise displaced. In the pulling-over machine organization illustrated the overlaying means cou'iprises wiper members mounted on too and side tacker arms which are moved inwardly after the upper has been pulled to lay the margin of the upper over the insole and which also carry tackcrs for fastening the upper in overlaid position, and the shoe is positioned relatively to said members to receive the light overlaying pressure by depression of the sole rest. After the overlaying members in the construction shown have advanced across the outer edge of the insole, and it may be substantially at the time when the grippers are tripped to release the upper and before the overlaying members have completed their inward movement, increased overlaying pressure is brougl'it to bear on the margin of the upper by relative movement between the overlaying members and the shoe, such movement in the construction herein sh'cf n resulting from a retractive movement of the sole rest, permitting the shoe to react against the overlaying members and to be pressed toward said members also by reaction of a yielding shoe support which sustains the shoe against the overlaying pres sure. In this manner the upper is held offectively against loss .of the pulling-over tension and is pressed firmly into position to receive the fastening tacks.

The above and other features of the invention, including also a novel construction and arrangement of fastening mechanism and certain detailsof construction and comliiinations of parts, will now be described with reference to the accompanying drawand pointed out in the claims.

The invention is herein illustrated as enibodied in a well known type of pulling-over machine the general characteristic features of which are shown and described in detail in various prior United States Letters Patent including particularly Patent No. 1,029,387, granted on June 11, 1912 upon an application of R. F. -McFeely, and in view of such priordisclosur'e the details of con struction of the illustrative machine,

far as they are not modified for the purposes of this invention, will be described only in brief terms. For purposes of illustration, moreover, the invention is: herein shown in its .application to a machine embodying features particularly designed for operation upon arctic shoes or shoes of similar type, as described and claimed in United States Letters Patent No. 1,501,053 granted on July 15, 1924 upon an application of Bernhardt J orgensen. It is to be understood, however, that the invention in many of its aspects is not limited to machines of the particular type illustrated.

The machine comprises in its general organization a toe gripper 2 connected to an updraw lever l, side grippers 6 connected to updraw levers 8, means comprising cam slides 10 and 12 operated by cams on a cam shaft 14 for imparting operative movement through springs 16 to the levers 4 and 8 re-- spectively for pulling the upper over the last against the resistance of a sole rest 18, .side clamp arms 20 which carry yieldable presser pads 22 and are swung inwardly into supporting and holding engagement with the shoe, and overlaying and tacking devices for the toe and the opposite sides of the forepart of the shoe carried respectively by a toe tacker arm 24 and side tacker arms 26. In the operation of machines of this type the starting of the machine is followed by closing and updraw movement of tlfie several grippers accompanied also by a slight depression of the sole rest 18 against the pressure of its return spring 25 through the operation of a cam 28 on the end of the cam Shaft lt upon a roll 30 which is mounted on the pivoted solerest carrier 32. After the upper pulling operation the machine comes to rest to permit inspection of the work and any adjustment which may be necessary. When the machine is again started the side clamp arms 20' are swung into supporting and holding engagement with the forepart of the .shoe and either innnediatelythereafter or following a second pause in the operation of the machine, the grippers are forced yieldingly inward over the shoe bottom to overoraw the upper and the several overlaying and tacking devices also are moved inwardly, these devices finally causing the grippers to release the upper by engagement with tripping devices 27 and then driving the upper fastening tacks, the mechanism for effecting the overdraw movement of the overlaying and tacking devices not being shown herein in detail since it is fully illustrated and described in the prior Mc- Feely patent above mentioned.

In the machine herein shown the side grippers comprise, in addition to gripper aws 34 which are arranged to engage the upper substantially at the location of the usual tip seam, a pair of gripper jaws 36 M il eely, and con' prises a yieldablc ovcrl positioned at each side of the last at the rear of the jaws 34 and constructed for continuous engagement with a portion of the margin of the upper extending along the ball of the last and thence rearwardly toward or into the shank. As illustrated in Figs. 2 and 3, the rear portions of the jaws 36 are curved inwardly in substantial conformity to the inward curve of the edge of the last bot-tom at the rear end of the ball of the last, and as shown also more partic ularly in Fig. 3 the outer edges of these jaws are likewise curved in substantial or approximate conformity to the lengthwise slope of the last bottom from the ball rearwardly into the shank, the rear ends of the aws thus extending downwardly into position tor convenient engagement with the margin of the upper along its receding edge line as well as into position to insure efii'ectiveness of the gripper in the upper pulling and overdrawing operations upon portions of the upper at and adjacent to the rear end of the ball of the last. As thus constructed the side grippers position and hold the upper substantially as close to the lateral periphery of the last adjacent to the edge of the last bottom along the inwardly curved portion of the surface of the last at and adjacent to the rear end of the ball as they do in relation to portions of. the last extending farther forwardly along the forepart, and in the overdrawing operation portions of the upper at and beyond the rear end of the ball are drawn inward over the margin of the insole substantially as far and with as hard a pull as the other portions of the upper which are engaged by the side grippers, with the result that the pullingover operation is rendered adequately! effective along the entire forepart of the shoe as far back as the shank.

The overl ying and tacking mechanism i ied by the toe tacker arm 24lmay be and is herein iown as of substantially the same construction as illustrated in the McFeely patent before mentioned and more in def-iii as to crtain features of the overlaying mechanisin in Patent No. 1,135,95- l, granted. on April 13, 1915 upon an application oil" 7. l

ing wiper 38, a tack holder 40 and a tack driver 412. The construction heroin illustra ted is adapted for driving a single tank at the end of the toe, but it will be under stood that the number and arrangement oi the toe tacks may be varied as desired. Portions of: the side overlaying and tacking dev'icescari'ied by the side tacker arms 20 ai'enlso shown as of substantially the same construction as in said prior patents, such devices comprising a pair of overlaying wipers lei at each side of the shoe having upturned inner ends to guide them over the edge of the shoe bottom and yieldingly controlled as to rocking and lengthwise movements by means of a spring t6, and tack holders 48 and 50 with corresponding tack drivers 52 operated by a driver bar 54:. As illustrated, the tack holder 48 is arranged to hold two tacks in position to be driven by the corresponding pair of tack drivers, these tacks being arranged to be applied to the shoe at or near the location of the tip seam where the shoe is provided with a tip, and the tack holder 50 with its corresponding driver is arranged for inserting a tack a short distance at the rear of the tip seam location. It will be understood that the tack holders 48 and 50 with the correspond ing drivers are swiveled for turning movement in accordance with the lengthwise contour of the edge of the shoe bottom, the extent of projection of these tackers over the shoe bottom being determined by a plate 56 located under the tack block and arranged to engage a stop 58 on the underlying side clamp arm.

In the construction herein shown there is provided also means for overlaying a portion of the margin of the upper at each side of the shoe in the rear of the wipers it and extending over and beyond the rear end of the ball of the last, together with means for driving a tack at each side at or near the rear end of the hall. For this purpose there is secured to each side tacker arm 26 a plate 60 which carries a pivot rod 62 on which is mounted a plate 6 L for swinging movement transversely of the edge of the shoe bottom. The plate (it carries near its lower end a tack holder 66 which is herein shown as constructed substantially as illustrated in United States Letters Patent No. 1279,6291, granted on September 2a, 1918, upon an application of ()rrell Ashton. Associated with the tack holder 66 is a driver (58 arranged to be operated by a swinging arm 70 which is pivoted on the plate 6% and slotted to receive a pin 72 projctiug from the driver bar 54 for imparting operative movementto the driver 68. A spring Tl connected at one end to a. pin on the plate 6% and at its other end to a pin 76 projecting through a slot in the plate li-il. tends to swing the latter plate and its supported tack holding and driving means toward the shoe, the position of the plate relatively to the shoe and the consequent extent of projection of the tack holder over the shoe bot tom being determined by a stop 78 on the front of a plate 80 which is secured adjustably by means of a screw and slot connection to the lower end of the plate 64. The rearmost tacker thus adjusts itself automatically relatively to the edge of the shoe bottom for driving its tack at a predetermined distance trom the edge. In the construetion shown and in accordance with this invention the position of the rearmost tack lei'igthwise of the edge of the shoe bottom may be adjusted, as tor ditlerent sizes of shoes, by means of a nut S t against which the plate (it is normally pressed by means of a spring 86 on the pivot pin 62.

Pivotally mounted on the lower end oi": the plate 6% below the tack holder 66 are a pair or overlaying members 88 which in view or their usual characteristic function may be conveniently termed wipers, these members in the construction shown having at their front ends rolls 90 to assist in eliminating undesirable frictional pressure of the members against the shoe materials at the edge of the shoe bottom. Springs 92 connected respectively to the rear ends of the members 88 and to pins on the plate 6st tend to swing these members about their pivots in a direction for applying holding pressure to the margin of the upper over the shoe bottom while pern'iitting them to yield each independently of the other in response to resistance of the shoe materials, the normal position of the members being adjustably determined by step screws 94 which. are carried by the plate 80 and arranged to engage underneath the members 88 in front of their pivotal axes. It will be noted that the overlaying men'ibers or wipers 88 are located respectively at opposite sides of the tack holder 66 and closely adjacent to the tacking point, the foremost member being arranged to engage a portion of the upper over the ball of the last and the rearmost mem her to en age a portion of the upper over the receding c rved portion of the last bottom beyond the rear end of the ball. With this arrangement of the members, the provision for independent yield of each member transversely ot' the plane of the shoe bottom has important advantages, since it permits both members to operate with equally effective results to hold. the stock notwithstanding the diti'erences in contour ot the ditlerent portions of the last bottom over which the respective members operate, and the provision for separate adjustment of the ditleii'ent members is also of advantage in adapting the mechanism to different shapes of shoes.

In order to avoid under-arable pressure of the toe and side wipers 38 and let and or": the members 88 against. the upper opposite to the edge face of; the sole or insole such as migl'it tend to double up or otherwise displace the margin of a flexible or yielding insole like that herein shown, the machine is provided, in accordance with this invention, with means for depressing the last prior to the advance ot the several overlaying mem bers over the edge oi the shoe. bottom and after its first depression eQi'ected as usual in machines of the illustrative type in the course of the pulling movement otthe grippers. This is etl'ected through the provi* sion of a projection 96 (Fig. 8) on the sole rest rocking cam 28 whereby the sole rest 18 is rocked about its axis from the dotted to the full line position illustrated in Fig. i to locate tie insole in a slightly lower plane relatively to the overlaying means, after its first depression by the usual rise 98 on the cam. lln the construction shown the second depression of the last takes place after the clamping and supporting pads 22 have engaged the shoe and at about the time when the taclrer arms 2% and 26 begin their inward movement to aid the shoe. As soon as the overlaying members have moved inwardly beyond the edge of the insole, and in the conitruction shown at about the time when the several grippers are tripped to ause them to relcus'e the mar 'in of the upper, the cam 28 in its couti led movement carries the projection 96 beyond its operative position, permitting the spring 25 to retract the sole rest, and 'iorinitting reaction of the side clamping and supporting devices, which are held against the shoe with con'iparatively heavy pressure, to force the shoe upwardly against the overlaying members, such upward movement of the shoe and its own resilience, combined with pressure of the wiper controlling springs 46 and serving to insure that the n'largin of the upper shall be effectually clamped against the insole in such manner as to prevent reaction of the upper and consequcnt loss of the pulling-over tension prior to the oriving of the tacks. It will be further evident that depression of the shoe after the side clamping and supporting devices have been moved to operative position assists in tightening the upper in preparation. for the overlaying operation.

In the operation of the machine, briefly summarized, the operator presents a shoe with its sole or insole on the bottom of the last against the sole rest 18 and arranges the margin of the upper within the open jaws of the toe and side grippers and then starts the iachine by depression of the usual starting treadle, whereupon the grippers are operated to pull the upper and the sole rest 18 is rocked downward, as usual'in machines of the illustrative type, by the action of the cam projection 98 (Fig. 8) on the cam 28, the machine then coming to rest with the upper under tension to permil: inspection and any necessary adjustment. Following a subsequent starting of the machine the side clamping and shoe supporting devices 22 are swung into operative engagement with the shoe. Either im mediately thereafter, or following a further rest in the cycle of operations, the toe and side grippers are swung inwardly to overdraw the upper, accompanied by the toe and side taclrer arms which force the several overlaying members or wipers into engagement with the tensioned upper, these members being permitted to yield both up wardly and backwardly against the tension of their controlling springs in response to resistance of the upper still held in the grippers, as will be understood by reference to l, the provision for backward yield of the members 88 being afforded by the spriugsfl. Before the overlaying memhers advance across the edge of the shoe bottom the last is depressed to the position illustrated in Fig. 4 by operation of the cam projection 96 on the sole rest. As the tacker arms continue their inward movement they cause the grippers finally to release the upper through engagement with the tripping devices 27, and at about the same time the retractive movement oi the sole rest per mits the shoe to be forced upwardly against the overlaying members by the reaction of the shoe clamping and supporting devices, thus increasing the pressure of said members on the shoe and positioning the shoe closer to the tack holders for the tacking operation. The tacker arms having com pleted their inward i'novement, and the rearmost taclrers having adjusted themselves relatively to the edge of the shoe bottom, the several tacks are driven, after which the parts return to their starting positions and the shoe is released.

It will be understood that the invention is by no means limited in utility to the manufacture of shoes of the particular kind herein illustrated, but is applicable to the manufacture of various types of shoes including welt-and turn shoes as well as shoes of the hiicKay type, and to shoes made of various materials. 7

In the appended claims the term sole is used generally for convenience to define that portion of the shoe to which the margin of the upper is fastened in lasting, irrespective ot the type of shoe, and is thus inclusive of the insole of a welt or a McKay shoe as well as of the sole of a turn shoe.
