Definitions
- This invention relates primarily to lasting machines, and is herein illustrated as applied to a machine constructed generally as disclosed in United States Letters Patent No. 2,075,852, granted on April, 1937, on an application of B. Jorgensen, but modified in. certain respects as f-urther disclosed in Letters Patent No. 2,101,069, granted on December 7, 1937, also lon an application of B. Jorgensen. It will be understood, however, that in various novel aspects the invention is not limited to machine organizations of that particular character. f
- a machine of the type illustrated in the abovementioned Letters Patent is provided with toelasting means which tensions the toe-end portion of the upper and wipes it heightwise of the last in response ⁇ to heightwise movement of the last, the last and shoe being moved in this manner against the resistance of a spring-controlled toe rest and a spring-.controlled heel-end support -by presser feet engaging the insole near its toe and heel ends, respectively.
- the shoe is held against lengthwise displacement in a heelward direction by a heel rest comprising a exible band which embraces and clampsthe shoe about its heel end and partakes of the heightwise movement of the shoe.
- the toe-lasting means further includes wipers which after such heightwise movement of the shoe wipe the margin of the toe end of the upper inwardly over the insole, whereupon the above-mentioned presser feet eng-aging the toe and heel ends of the insole are somewhat retracted to permit the shoe to be pressed more forcibly against the toe wipers by the spring-controlled toe rest.
- wipers which after such heightwise movement of the shoe wipe the margin of the toe end of the upper inwardly over the insole, whereupon the above-mentioned presser feet eng-aging the toe and heel ends of the insole are somewhat retracted to permit the shoe to be pressed more forcibly against the toe wipers by the spring-controlled toe rest.
- 2,075,852 is a device which by engagement with the bottom of the forepart of the shoe may tip the shoe laterally to position it in proper relation'to the toe wipers prior to the heightwise movement of the shoe by the presser feet, the heel rest being so ⁇ mounted as to permit it to tip with the shoe.
- This device is thereafter retracted from the shoe so as not to interfere with substantial equalization of the pressure of the wipers on the margin of the upper at the opposite sides of the toe when the shoe is pressed more firmly against the wipers by the toe rest.
- the construction herein shown is such that at the time when the shoe is tipped to position ⁇ it relatively to the toe wipers it is engaged by the heel rest with comparatively light pressure, so that the heel rest may more readily tip on vits support andthe shoe also may tip somewhat relatively to the heel rest, after which the pressure of the heel restk on the shoe is increased to insure that the shoe will be properly held against lengthwise -displacement in the toe-lastingoperation. Provision for engagement of the shoe by the heel rest with such light pressure is afforded by adjusting means heretofore included in machines of the illustrated type, as moreparticularly hereinafter described.
- the increaseoi the pressure-of the heel rest on the shoe, as herein illustrated, is ⁇ effected by forcing the opposite endsV of the exible heel band apart, which tends to ⁇ straighten'the band and thereby tightens it against the ⁇ heel-end facey of the shoe.
- the opposite ends of the band are 4connected to a toggle device which extends over the bottom of thefheel end of the-shoe and is operated yieldingly'through a spring to force the ends of the band apart by a member which is supported bythe toggle device and is movable toward the .bottom ofthe shoe.
- This member is operated by another member which takes the place of the presser foot heretofore provided for engaging the heel end.
- the present invention provides a construction whereby the pressure of the heel rest on the shoe 1 is somewhat relieved at this time to facilitate the tipping of the shoe.
- the heel-end support for the shoes which is provided with a last pin arranged to enter the usual spindle hole in the heel end of each last, is so constructed that the last pin is movable in directions widthwise of the shoes to diierent positions corresponding to such different positions of the heel ends of right and left shoes, relatively adjustable stops being provided for determining the different -positions of a block on which the pin is mounted.
- the invention further provides means whereby the heel rest and the above-mentioned member which engages the heel end of each insole to impart the heightwise movement to the heel end of the shoe are caused to assume different positions for right and left shoes, respectively, in accordance with the different positions of the last pin.
- the heel rest and this member are connected to the block which supports the last'l pin to move in directions widthwise of the shoes with the pin.
- the insole-engaging member is thus positioned for engagement with the heel end of each insole in a location substantially midway between the opposite sides of the shoe, thus avoiding any tendency for it to .tip the shoe such as might result from its engagement with the insole nearer one side of the shoe than the other side.
- the other member which acts on this member as above described to impart the heightwise movement to the shoe is so constructed as to act eiTectively thereon in whatever position the insole-engaging member may be located.

(c1. iz-iz) 47 Claims.
This invention relates primarily to lasting machines, and is herein illustrated as applied to a machine constructed generally as disclosed in United States Letters Patent No. 2,075,852, granted on April, 1937, on an application of B. Jorgensen, but modified in. certain respects as f-urther disclosed in Letters Patent No. 2,101,069, granted on December 7, 1937, also lon an application of B. Jorgensen. It will be understood, however, that in various novel aspects the invention is not limited to machine organizations of that particular character. f
A machine of the type illustrated in the abovementioned Letters Patent is provided with toelasting means which tensions the toe-end portion of the upper and wipes it heightwise of the last in response `to heightwise movement of the last, the last and shoe being moved in this manner against the resistance of a spring-controlled toe rest and a spring-.controlled heel-end support -by presser feet engaging the insole near its toe and heel ends, respectively. In this operation the shoe is held against lengthwise displacement in a heelward direction by a heel rest comprising a exible band which embraces and clampsthe shoe about its heel end and partakes of the heightwise movement of the shoe. The toe-lasting means further includes wipers which after such heightwise movement of the shoe wipe the margin of the toe end of the upper inwardly over the insole, whereupon the above-mentioned presser feet eng-aging the toe and heel ends of the insole are somewhat retracted to permit the shoe to be pressed more forcibly against the toe wipers by the spring-controlled toe rest. Associated with the toe-lastingmeans, as disclosed moreparticularly in Letters Patent No. 2,075,852, is a device which by engagement with the bottom of the forepart of the shoe may tip the shoe laterally to position it in proper relation'to the toe wipers prior to the heightwise movement of the shoe by the presser feet, the heel rest being so `mounted as to permit it to tip with the shoe. This device is thereafter retracted from the shoe so as not to interfere with substantial equalization of the pressure of the wipers on the margin of the upper at the opposite sides of the toe when the shoe is pressed more firmly against the wipers by the toe rest.
While the means for tipping the shoe laterally as above described by engagement with the bottom of its forepart has proved to be generally satisfactory, it has been found that under some conditions the heel rest does not leave the shoe sufciently free for lateral tipping movements to insure that it will begaccurately positioned in the best relation tothe toe wipers by the forepartengaging means. An` object of the present invention, in one of its aspects, accordingly, is to improve the machine in this respect. For the purpose in view, the construction herein shown is such that at the time when the shoe is tipped to position` it relatively to the toe wipers it is engaged by the heel rest with comparatively light pressure, so that the heel rest may more readily tip on vits support andthe shoe also may tip somewhat relatively to the heel rest, after which the pressure of the heel restk on the shoe is increased to insure that the shoe will be properly held against lengthwise -displacement in the toe-lastingoperation. Provision for engagement of the shoe by the heel rest with such light pressure is afforded by adjusting means heretofore included in machines of the illustrated type, as moreparticularly hereinafter described. The increaseoi the pressure-of the heel rest on the shoe, as herein illustrated, is `effected by forcing the opposite endsV of the exible heel band apart, which tends to` straighten'the band and thereby tightens it against the `heel-end facey of the shoe. For this purpose the opposite ends of the band are 4connected to a toggle device which extends over the bottom of thefheel end of the-shoe and is operated yieldingly'through a spring to force the ends of the band apart by a member which is supported bythe toggle device and is movable toward the .bottom ofthe shoe. This member is operated by another member which takes the place of the presser foot heretofore provided for engaging the heel end. of the insole and for moving the shoe heightwise relatively to the toe-lasting means as hereinabove described. In the construction `herein shown such heightwise movement of the heel end of the shoe is effected through the member which is supported by the toggle device, this member being movable by the other member into engagement with the insole and being then further movable thus to act on the shoe.
When the means for imparting the heightwise movement to the shoe is retracted to permit the toe end of the shoe to be pressedA more forcibly against the toe Wipers by the toe rest, as hereinbefore described, it is likewise desirable that the shoe be as free as possible to tip laterally so that the pressure of the toe wipers on the margin of the upper at the opposite sides vof the toe will be substantially equalized. Accordingly, the present invention provides a construction whereby the pressure of the heel rest on the shoe 1 is somewhat relieved at this time to facilitate the tipping of the shoe. Such relief of pressure in the construction herein shown results from the retractive movement of the member above referred to as taking the place of the usual heel presser foot, since this permits a corresponding retractive movement of the toggle device controlling the ends of the heel band, so that the pressure of the band on the heel-end face of the shoe is decreased.
When right and left shoes are presented with their toe ends in position to be operated upon by the toe-lasting means in a machine of the illustrated type, it is desirable under some conditions that their heel ends shall occupy positions in which they are somewhat oiset laterally in opposite directions respectively. Accordingly, in
the construction herein shown the heel-end support for the shoes, which is provided with a last pin arranged to enter the usual spindle hole in the heel end of each last, is so constructed that the last pin is movable in directions widthwise of the shoes to diierent positions corresponding to such different positions of the heel ends of right and left shoes, relatively adjustable stops being provided for determining the different -positions of a block on which the pin is mounted. The invention further provides means whereby the heel rest and the above-mentioned member which engages the heel end of each insole to impart the heightwise movement to the heel end of the shoe are caused to assume different positions for right and left shoes, respectively, in accordance with the different positions of the last pin. For this purpose, in the construction herein shown, the heel rest and this member are connected to the block which supports the last'l pin to move in directions widthwise of the shoes with the pin. The insole-engaging member is thus positioned for engagement with the heel end of each insole in a location substantially midway between the opposite sides of the shoe, thus avoiding any tendency for it to .tip the shoe such as might result from its engagement with the insole nearer one side of the shoe than the other side. The other member which acts on this member as above described to impart the heightwise movement to the shoe is so constructed as to act eiTectively thereon in whatever position the insole-engaging member may be located.
'I'he above and other features of the invention, including various novel details of construction and combinations of parts, will now be more particularly described with reference to the accompanying drawings and thereafter pointed out in the claims.

Fig. 8 is a View in vertical section illustrating the relation of the toe end of the shoe to the toe-lasting means at the time when the shoe is thus forced against the toe Wipers.
In a machine of the illustrated type the last and shoe, herein sometimes referred to inclusively as the shoe, are supported at the toe end by a toe rest 2 and at the heel end by a vertically movable slide 4, the toe rest and the slide being controlled respectively by springs 6 and 8 against the resistance of which they are movable downwardly with the shoe, in the course of the power operation of the machine, relatively to means provided for lasting the toe end of the shoe. The toe-lasting means includes a gripper I0 which grips the margin of the toe end of the upper and applies a pull to the upper in response to the downward movement of the last, a toe former I2 which at the same time embraces the upper around the toe and Wipes it heightwise of the last, and wipers Irl which are thereafter operated to wipe the margin of the toe end of the upper inwardly over an insole on the last into position to be secured to the insole by an adhesive.
Similarly to the disclosure of Letters Patent No. 2,101,069, the heel support slide 4 carries a last pin I6 arranged to enter the usual spindle hole in the heel end of the last, this pin being mounted on a block I8 supported on a post 20 which is vertically adjustable in a holder 22 guided for movements in directions lengthwise of the shoe on the upper end of the-slide Il. By rack-and-pinion mechanism operated by a hand crank 24 the post 20 may be adjusted vertically to different positions for shoes of different styles or sizes. Similarly also to the disclosure of the last-mentioned Letters Patent, the machine herein shown is not provided with heel-lasting means, but has a heel rest 26 for engaging the heel end of the shoe to assist 'in controlling the shoe in the toe-lasting operation. The heel rest includes a flexible heel band 28 of leather or other suitable material arranged to embrace the heel end of the shoe and secured to a chain 30 (Figs. 3 and 5) the end links of which are pivotally connected by pins 3l to arms 32 mounted for swinging movements in directions widthwise of the shoe on a crossbar 34. 'I'his crossbar is provided midway between its opposite ends with a stem 36 extending horizontally lengthwise of the shoe and rotatably mounted in a socket formed in the upper end of a holder 38. In engagement with the end of the stem 3B is a ball thrust bearing 40 to facilitate turning of the heel rest about the axis of the stem. Secured to the intermediate link 4Z (Fig. 1) of the chain 30 is a Ashort rod 44 which in the construction herein shown, as distinguished from the construction disclosed in Letters Patent No. 2,101,069, extends into a horizontal slot 4S in the crossbar 34, not
only to support the intermediate portion of the heel band but also to permit movements of that portion of lthe band relatively to the crossbar in directions widt-hwise of the shoes for a purpose `hereinafter explained. The holder v38 has a depending shank portion 48 vertically adjustable `bymeans of' a lever 50 in a guideway formed in `a slide 52, substantially as disclosed in the lastmentioned Letters Patent, the slide 52l being movable indirections lengthwise of the shoe on a pair of horizontal rods 54 which are secured to the shoe support slide 4. By reason of thisconstruction the heel band moves with theshoe and the slide 4 in directions heightwise of the shoe,
`but is movable relatively to the shoe in direcof the machine. The movement of the heel band in this direction is limited by engagement of the slide 52 Vwith washers 58 (Fig. 2) mounted on the rods 54. Substantially at the time when the movement of the heel band toward the shoe is stopped by the washers 58 the shoe is `carried into engagement with `the band by movement of the holder 22 inthe opposite direction along guideways on the slide 4. The means for thus moving the holder 22 is more fully disclosed in Letters Patent No. 2,026,539, granted on January 7, 1936, on an application of B. Jorgensen. Briefly, as shown particularly in Fig'. 2, there is supported on a bracket 50 fast on the slide 4 a slide 62 movable relatively to the bracket in di `rections lengthwise of the shoe, and rotatably mounted in the slide 62 vis a shaft 64 connected by bevel gears 58 to a shaft alsorotata'bly mounted in the slide 62. The shaft 68 is provided with screw threads in engagement with a nut 10 mounted in a recess in the holder 22. On the shaft 04 is a hand wheel 12 for turning it. It will thus be seen that by turning the hand wheel the holder 22 may be ladjusted in directions lengthwise of the shoe relatively to the slide 62 and that this slide and the holder are held by the adjusting means in fixed relation to each other to move as a unit in directions lengthwise of the shoe. By means of a link 14 the slide 52 is connected to gearing 10 which is supported on a bracket i8 fast on the rods 54 and by which return movement toward the left (Figs. l and 2) is imparted to the slide 52 and the holder 22 in response to engagement of the slide 52 with. an arm connected to the gearing when this slide is moved toward the right to carry the heel band away from the shoe, as fully disclosed in the last-mentioned Letters Patent. This operation results in compression of a spring 82 which surrounds the link 'I4 and is held between a nut 84 on the link and a plate 85 fast on the bracket 50. The slide 62 and the holder y22 are held in the positions to which they are thus moved by the link 'i4 by means of a spring-controlled latch 88 (Fig. l) which is pivoted on the bracket 60 and is arranged to engage a plate 90 on the slide 52. By means not herein shown, which is carried by the slide 52, the latch 88 is retracted from the plate 90 to release the slide 62 just before the movement of the slide 52 toward the shoe is stopped by the washers A58, whereupon the spring `band 28.
82 actsithrough the link 14 tomove the'slide Av|i2 and the holder` 22 toward the right and rthus'to carry the shoe `into engagement with the heel The previously mentioned downward moven ment of the shoe with the `toe rest 2 and the heel-support slide 4 takes place shortly after` the starting of the power operation of the machine, the heel band 28 having been applied to theshoe `as above described. This downward movement of the shoe is effected by depressing means acting on the toe and heel-end portions of the insole,
vThe toefend portion of the insole is engaged for this purpose by a presser foot 82 mounted on a pinl 94 which `is carried by a bracket `.06 fast `on an arm 9.8,this arm being mounted for forward swinging movement to carry the presser foot into position over the insole and for downward movement thereafter to depress the toe, end of the shoe. Theoperator swings the arm forwardly bymeans of a handle |00, and this movement of the arm results in the starting ofthe power operation of the machine. ward movement of `the heel-end portion of the shoe is eifected by a rod |02 which corresponds to the presser foot 8,2 shown in Letters Patent No. 2,101,069 but in the construction herein shown acts on the shoe through mechanism hereinafter described instead'of directlyl engaging the shoe. Like the earlier presser foot 52, the rod |02 is vertically adjustable in a carrier |04 which in the power operation of the machine swings the rod to a position over the shoe and also moves it downwardly. Supported on the aboveunentioned arm B8 which carries the toe presser foot 82 is mechanism constructed substantally as disclosed in `Letters Patent No. 2,075,852 for tipping the shoe laterally into proper relation to the toe wipers |4 if it is not already in that relation prior to the beginningjof the downward movement of the shoe. Briefly, this mechanism includesa member |06 mounted to swing in directions heightwise of the shoe about the pin 94 and provided with a `pair of downwardly extending lugs arranged tof engage the bottom of the forepart of the shoe nearits opposite sides, respectively, one of these lugs be ing` shown at |00 in Fig. l. Initially the member |05 is held in i'ixed relation to the arm 98 with its lugs |08 extending to positions somewhat lower than the presser` foot 92 by a pair of vpivotally connected toggle links ||`0 and ||2,the link ||0 being pivotally connected to the member |05 and the link ||2 being fast on a rockshaft ||4 in the bracket 05, Initially the toggle thus provided is held substantially straight by a `spring H6 to position the member |06 as above described. Accordingly, this member acts to tip a more complete understanding of the construction and operation of this mechanism Letters Patent No. 2,075,852 may be consulted.
It will be evident `that if the member |05 is to tip the shoe in the manner required to position it in proper relation to the toe wipers, the shoe `must be sufficiently `responsive to .theaction Corresponding down Immediately thereafter, in
of this member thereon. While the heel band 28 is so controlled as to permit it to tip with the shoe and while the ball thrust bearing 40 is provided to facilitate such tipping of the band, substantially as in the construction disclosed in Letters Patent No. 2,101,069, it is obvious that the'vgreater the pressure with which the shoe is held against the band the less freedom there is for the band to tip by reason of friction. In order, therefore, to afford increased insurance that under any conditions the member |66 will effectively perform its intended function, it is contemplated that for purposes of the present invention the heel band 28 will engage the shoe with comparatively light pressure, substantially less than that required to prevent heelward displacement of the shoe in the toe-lasting operation, at the time when the member |06 acts on the shoe. For this purpose the holder 22 which carries the last pin I6 will be adjusted so far toward the left by rotation of the hand wheel 12 that when the shoe has been moved into engagement with the heel band by the action of the spring 82 this spring will have so far eX- panded as to hold the shoe against the band with only light pressure. This will facilitate the turning of the stem 36 in its holder 33 and will also leave the shoe free to tip somewhat relatively to the band in response to the action of the member |06 thereon,
In order to render the heel band thereafter effective to hold the shoe against heelward displacement when the toe former I2 and the wipers I4 operate thereon, the invention in its illustrated embodiment provides mechanism for forcing the opposite ends of the band apart and for thereby tightening the band against the heelend face of the shoe by the tendency thus to straighten it. This mechanism comprises a toggle device |23 having a pair of toggle links |24 pivotally connected to heads formed on the upper ends of the pins 3| which connect the chain 30 to the arms 32, and having a crossbar |26 connecting the links |24 together and arranged to extend over the bottom of the heel end of the shoe. Slidingly mounted for vertical movements in this crossbar is a pin |28 having an enlarged lower end to limit its upward movement in the crossbar, and between the crossbar and nuts |30 threaded on the upper end of the pin is a compression spring |32 which normally holds the pin at the limit of its upward movement in the crossbar. Pivotally connected to the crossbar is a link |34 provided with a slot |36 (Fig. 1) through which extends a pin |38 sup- "7 ported in a forked upward extension |40 of the intermediate link 42 of the chain 30. Coiled about the pin |38 is a spring |42 portions of which are in engagement respectively with the upward extension of the chain link 42 and with the link |34, this spring tending to lift the crossbar |26 and holding it initially with the toggle links |24 in such positions that the heel end of the shoe will readily enter the heel band 28. When the shoe is pressed against the band by the spring 82 the parts are positioned substantially as illustrated in Figs. 3 and 4, with the band lightly clamping the shoe and the lower end of the pin |28 spaced above the insole. In the power operation of the machine a crossbar |44 formed on the lower end of the rod |02 is arranged to engage one of the nuts 30, or the pin |28 if the nuts are far enough down on the pin, and thereby to impart downward movement to the pin. When the parts are positioned as shown in Fig. 1, the member |06 has just performed its positioning action on the shoe and the crossbar |44 has begun to move the pin |28 downwardly, but Without any substantial increase as yet in the pressure of the heel band on the shoe. Immediately thereafter, as the pin is forced farther downwardly by the crossbar |44, the crossbar |26 is operated yieldingly through the spring |32 to cause the toggle links |24 to spread the opposite ends of the heel band far enough apart to increase substantially the pressure of the band on the heel-end face of the shoe, as illustrated in Fig. 5. In its downward movement the pin |28 arrives in position to engage the heel end of the insole substantially at the time when the toe presser foot 92 becomes eiective on the toe-end portion of the insole, and thereafter the crossbar |44 acts through the pin to impart downward movement to the heel end of the shoe simultaneously with the downward movement of its toe end by the toe presser foot. During the downward movement of the shoe, and thereafter as the toe wipers are operated to wipe the margin of the upper inwardly over the insole, the heel band 28 controlled as.
described eiectively prevents any heelward displacement of the shoe in response to the action of the toe-lasting means thereon.
In a machine of the illustrated type, after the toe wipers have wiped the margin of the upper inwardly over the insole, the means for depressing the shoe is retracted a short distance to permit the toe end of the shoe to be pressed more rmly up against the toe wipers by the spring-controlled toe rest. That is, in the machine herein shown, the arm 98 and the carrier |34 are moved upwardly a short distance for this purpose. Since the toe end of the shoe can actually receive but little upward movement toward the toe wipers, the machine herein shown is provided with means constructed substantially as heretofore for limiting upward movement of the heel support slide 4, sothat the heel end of the shoe will not be lifted far enough to tip the shoe relatively to the toe wipers. The construction and operation of this limiting means are disclosed in detail in Letters Patent No. 2,075,852. Briefly, there is provided a swinging arm |46 corresponding to the arm 410 shown in the last-mentioned Letters Patent, this arm supporting a pair of pawls |48 which by the downward movement of the arm are carried into engagement with teeth formed on a slide |50 mounted for vertical movements in a bracket |52 (Fig. 2) fast on the heel support slide 4. By the action of the arm |46 and the pawls |43 the slide |50 is thus locked against upward movement at the time when the toe wipers are operated to wipe the margin of the upper inwardly over the insole. There is, however, provision for a short upward movement of the slide 4 to permit the heel end of the shoe to be raised enough to compensate for such upward movement as the toe end of the shoe receives from the action of the toe rest 2, this movement of the slide 4 being limited by a lug |54 which is formed on the slide |50 and is spaced initially from the top of the bracket |52 as illustrated in Fig. 1. Between this lug and the bracket |52 is a spring |56 which holds the slide |50 initially in its normal relation to the slide 4. Since the rod |02 and its crossbar |44 are moved upwardly by the carrier |04 a greater distance than the heel support slide 4 is permitted to move, it will be evident that this results in a relief of the pressure of the heel band 28 on the heel-end face of the shoe, since the ends of the band are permitted by the toggle links |24 to move some-l the toe wipers on the margin of the upper at the opposite sides of the toe will be substantially equalized.
While machines of the illustrated type -have been provided heretofore with means whereby the toe wipers are adjusted automatically todifferent positions in `operating respectivelyon right and left shoes, it is desirable under some conditions, especially if there are pronounced differences `between right and left lasts with respect to lateral swing of the forepart, that the heel ends of the shoes shall occupy positions in which they are somewhat offset laterally in opposite directions relatively tothe toe-lasting means. In the machine herein shown, therefore, the block I8 which supports the last pin` |6 is mounted for movements in directions widthwiseo-f the shoes in a straight guideway |51 (Fig. 1) formed in the upper end of the post 20,the movements of the block in opposite `directions being limited by engagement of a bar |58 projecting from `the block with stops |80 (Figs. l and 2) which are adjustable toward and from each other along a guideway on the post 20. Thestops are adjusted simultaneously equal distances toward or from each other by a screw |62 having right and left threads in engagement respectively with the differentstops, the screw being provided with a flange |64 which extends into a recess in the post 20 to prevent any lengthwise movement of the screw. In presenting the work to the machine the operator moves the block I8 by means `of the last to the position determined by one of the stops |60 if a right shoe is to be operated upon and to the position determinedl by the `other stop `if a left shoe is to be operated upon. The last pin I8 on theblock |8Yis made somewhat smaller in diameter than .the spindle hole in `the last to permit such tipping movement of the last and shoe as may be required for the member to position the shoe in proper relation to the toe wipers in the manner hereinbefore described.
The construction herein shown is further such that the heel band 28 and the pin |20 through which the heelendof each shoe isdepressed are caused to assume different positions in accordance with the positions `of the last pin IE for right and left shoes, respectively. For this purpose the bar |58 extending from the block I8 is connected by a series of links |60, |68 and |10 to a block |12 which is mounted on'the previously mentioned rod 44`e'xtending from the `intermediate link 42 of the chain 30 into the slot 46 of the crossbar 34. Accordingly, movements of the block |8 in directions widthwise of the shoes are accompanied by corresponding movements of the intermediate portion of the heel band 28, the rod 44 moving along the slot `llt; and since the link |34 connects the chain link 42 to the crossbar |28, corresponding movements also are imparted to the pin |28 in this crossbar and, through the toggle links |24, to the ends of `the heel band. The heel band, therefore, is adjusted to a laterally offset position for a right 'or a left shoe, so that it will be in proper alinement with the heel end of the shoe, as will be evident by reference to Figs. 3 and 5, and the pin |28 also is so positioned that it will engage the bottom of the heel end of each shoe substantially midway between the opposite sides of the shoe, thus avoiding any tendency which it might otherwise have to tip the shoe laterally when it moves it downwardly. Between the block |12 and portions of the upward extension |40 of the intermediate link 42 of the chain 30 are mounted two comparatively light springs |14 which tend to maintain the heel band in a horizontal position but permit it to tip with the shoe in the manner hereinbeiore described when the shoe is tipped `by the member |06. It will be evident that the series of links connecting the bar |58 Ito the yblock |12, which links are relatively movable only about axes extending widthwise of the shoe, permit relative movements of the heel band and the heel-end support for the shoe in `directions lengthwise and heightwise or" the shoe.
The manner `of operation of the machine, in so far as it isof interest with reference to the present invention, will now be briefly 'summarized In presenting the work` to the machine the operator mounts the heel end of the last on the pin lIt and theblock |8 and by means of the last moves the blockA to the position determined by one or the other of the stops |80, depending upon whether theishoe isa right or a left shoe, if the block is not already in that position. Through the connections between the `block I8 and the heel band `28 andthe pin |28 any movement thus imparted to the blockis` imparted also to the heel band and to the pin, so that the heel band is in proper relation to the shoe widthwise thereof and the pin will be substantially midway between the opposite sides of the shoe when it is over the heel end of the shoe. The operator then releases the slide 52v to the action ofthe spring 58 to cause the slide to carry the heel band toward the shoe. Near the end of this movement of the slide the latch 88 is retracted to release the holder 22 to the action of the spring 82, whereupon this spring moves'theshoe lengthwise `into engagement with the heel band, `the holder 22 having been previously so adjustedwby the hand wheel 12V that thepressure of the heel band on the shoe as the result of this action of the spring 82 isa comparatively light pressure. The relation at this time between the shoe and the heel band is illustrated` in Figs. 3 and 4. Thereafter the operator closesthe toe gripper I0 on the margin of the toe end of the upper by the means provided for that purpose in a machine of theillustrated type. By means `of theV handle |00 he then swings the arm 98 vforwardly to bring the toe presser foot 92 and the shoe-positioning device |08 to positions over the bottom ofthe forepart ofthe shoe, the power operation of the machine being started by this movement of the arm. Immediately after the machine is thus started the arm 98 and the carrier |04 are moved downwardly, the carrier also receiving a swinging movement to carry the crossbarv |44 on the rod |02 `to a position over `the upper end of the pin |28. Before the toe lpresser foot 92 engages the insole the member |08 vacts on the bottomofthe Aforepar't of the shoe to .f
tipthe shoe laterally into `proper relation to the `Vtoevwipers if it isvnot already in that relation, as
illustrated in Fig. l. ISuch tipping of the shoe is facilitated `by the fact that `the heel band at this time engages thev shoe with comparatively light pressure, as above described, the band be ing permitted to tip with the shoe and the shoe also being capable of tipping more or less relatively to theband. Substantially at the time when the member |06 completes its positioning action on the shoe the crossbar |44 arrives in the position illustrated in Fig. l, having begun to swing the toggle links |24 but without any substantial increase as yet in the pressure of the heel band on the shoe. Thereafter, as the arm 98 and the carrier |84 continue their downward movements, the member |06 is swung upwardlyv away from the insole, the toe presser foot 92 then coming into engagement with the insole and acting during further movement of the arm 98 to depress the toe end of the shoe. As control of the toe end of the shoe is thus being transferred from the member |86 to the presser foot 92, the crossbar |44 acts through the spring |32 on the toggle links |24 to spread the ends of the heel band far enough apart to increase the pressure of the band on the heel-end face of the shoe, as illustrated in Fig. 5. Substantially at the time when the toe presser foot 92 begins to depress the toe end of the shoe the pin |28 has been moved downwardly far enough by the crossbar |44 to engage the heel end of the insole, as illustrated in Fig. 6, and, accordingly, both the toe and heel ends of the shoe are thereafter moved downwardly together to cause the gripper I to apply a pull to the toe end of the upper and the toe former I2 to wipe it heightwise of the last. At the end cf such downward movement of the shoe the toe wipers I4 are operated to wipe the margin of the toe end of the upper inwardly over the insole, andl at substantially thesame time the arm |46 is swung downwardlyy to carry the pawls |48 into engagement with the teeth of the slide |53. Thereafterthe arm 98 and the carrier |34 are moved upward a short distance to permit the toe end of the shoe to be forced more rmly up against the toe wipers by the spring-controlled toe rest 2, as illustrated in Fig. 8. By reason of the action of the pawls |48 on the slide |53, only a very short upward movement of the heel support slide 4 and the heel end ofthe shoe is at this time permitted, and, accordingly, the upward movement of the carrier |4 and the crossbar |44 permits enough retractive movement of the toggle links |24 to relieve substantially the pressure of the heel band on the heelend face of the shoe, so that the shoe can` more readily tip in such manner as to insure that the pressure of the toe wipers on the upper at the opposite sides of the toe will be substantially equalized. Before the toe wipers are withdrawn from over the bottom of the shoe the arm 98 and the carrier |04 are again moved downwardly far enough to relieve the pressure of the shoe on the wipers, after which the various parts of the machine are returned to their starting positions in a manner which requires no further description for an understanding of the present invention.
