Definitions
- This invention relates to lasting machines, and is herein illustrated as applied to a machine of the same gene-ral character as disclosed in United States Letters Patent No. 1,843,232, granted on February 2, 1932, upon an application of B. Jorgensen, but modied in certain respects as further disclosed mainly in Lette-rs Patent No. 2,026,539, granted on January 7, 1936, also upon an application of B. Jorgensen. It is to be understood, however, that in various aspects the invention is not limited to machines of the type therein disclosed.
- Machines of the above-mentioned type are commonly used in lasting tennis shoes or the like having uppers of textile fabric and rubber shoe bottom parts which are vulcanized while the shoes are on their lasts.
- Such a machine includes a toe former which extends around the toe end and along portions of the sides of the upper and wipes the upper height-wise of the last, overlaying members which lay o-r wipe the margin of the portions of the upper embraced by the toe former inwardly over an insole on the last into position toadhere to the insole, and ,side-lasting devices 525 which conform the upper to the sides of the last and lay its margin inwardly over the insole first along the shank portion of the shoe and thereafter in locations nearer the toe end of the shoe adjacent to the toe former and the above-mentioned overlaying members.
- An object of the present invention is to provide a construction such as to produce improved results along the sides of the forepart, and more particularly, in one aspect, to afford better insurance than heretofore against the formation of any upstanding wrinkles in the margin of the upper over the insole between the above-mentioned overlaying members and the side-lasting devices.
- Treatment which shoes of the above-mentioned type ordi- -sn narily receive between the lasting operation and the laying of the outsole render it especially desirable that no .such wrinkles be present.
- the machine herein shown is provided with novel means constructed and arf.
- nexible straps are arranged to extend heightwise of the shoe between the toe former and portions of the sides of the upper and to eX- tend also into positions where they are overlapped and forced inwardly over the insole against the margin of the upper by the above-mentioned overlaying members and are thereafter overlapped and pressed upon the margin of the upper also by the side-lasting devices.
- Springs connected tothe straps are arranged to hold them taut while permitting them thus to be forced inwardly over the insole.
- the straps in the construction shown extend between the toe former and portions of the sides of the upper, they cooperate with the toe form-er in wiping the upper heightwise of the last and, in fact, increase the effectiveness of the wiping action on the sides of the upper where they are located, the straps preferably being formed of textile fabric, such as canvas, adapted to act with eiective friction on the fabric upper as well as to act effectively to press the margin of the upper rrnly on the insole.
- the straps are also arranged to extend beyond the toe former along the sides ofthe upper and to be overlapped by the side-lasting devices in conforming the upper to the sides of the last, thus affording increased insurance against the formation of any wrinkles in the upper opposite the sides of the forepart of the last.
- Fig. 1 is a view in front elevation of a portion of a machine in which the invention is embodied
- Fig. 2 is a plan View of a portion of the machine sho-wn in Fig. 1, with parts broken away;
- Fig. 3 is a view partly in elevation and partly in section, showing portions of the machine as viewed from the right with reference to Fig. 1, the parts being shown in the positions which they occupy prior to the wiping of the upper heightwise of the last;
- Fig. 4 is a view similar to Fig. 3, showing the parts as they appear after the wiping of the upper heightwise of the last and the laying of its margin inwardly over the insole;
- Fig. 5 is a plan view, with parts broken away, illustrating conditions at the same stage in the operation of the machine as in Fig. 4.
- a last with an upper thereon is mounted at its heel end on a support 2 provided with a pin 4 which ⁇ extends into the spindle hole in the last, the support being yeldingly depressible with the last and shoe against the resistance of a spring V(not shown).
- a spring V (not shown)
- At its toe end the last is supported on an upper-engaging toe rest 6 (Figs. 3 and 4) yieldingly depressible against the resistance of a spring 8.
- a toe former Arranged to extend continuously around the toe end and along portions of the sides of the shoe is a toe former comprising a band l which may be made of comparatively hard leather or other material suitable for wiping the upper effectively heightwise of the last in response to depressionof the last.
- Such depression of the last is effected in the power operation of the machine by a toe presser foot l2 arranged to engage the toe end of an insole on the last and by a heel presser foot (not shown) which engages the heel end of the insole.
- the toe presser foot I2 is supported by an arm I4, a portion of which is shown in Fig. 1, this arm being swung forwardly by the operator to a position over the shoe and being then moved down- Wardly by power to depress the shoe, the arm having also thereon means which need not be particularly described for controlling the margin vofthe toe end of the upper in the lasting operation.
- the toe former or band i@ is supported and vcontrolled by means such as disclosed in Letters Patent No.
- the wipers comprise a pair of end wiper plates i6 (Fig. 2), and a pair of side wiper plates i8 for wiping the upper inwardly along the sides only oi the toe beyond the end plates.
- the side plates i8 are comparatively thin plates which are fast on arms 2li, only one of which is shown in Fig. 2, these arms being pivotally mounted for swinging movements laterally of the shoe on a casting 22 winch supports the wipers and their operating mechanism.
- the end plates i6 are connected together by a pin 26 for swinging movements laterally of the shoe, and in operation they are also advanced bodily lengthwise of the shoe relatively to the side plates It with portions of them overlapping these side plates.
- the end plates I6 are supported by a rack bar Z which is slidingly movable in the casting 22 and is operated thus to advance them lengthwise of the shoe
- the end plates and the side plates I8 are, closed laterally of the shoe by rack bars 28 also slidingly movable in the casting 22,
- Each of these rack bars is adjustably connected to a slide 3U which is connected by a link 32 to a lever Sli pivoted at 36 on the casting 22, the lever 34 being provided with a pin 38 arranged to act through a link 4t to close the corresponding end wiper plate It.
- Each lever 3Q serves also to operate the corresponding side wiper plate it by swinging the arm 20, the lever acting on the arm through a sliding connection 42 between the lever and the arm, as fully disclosed in
- the side wiper plates I3 are positioned initially far enough apart to provide ample room between them for shoes of diierent widths, and the links 4B are provided with slots i4 to receive the pins 38 and to delay the beginning of the closing movements of the end plates I until the side plates have been moved into substantially as close relation to the shoe as the end plates.
- each of these devices comprises a wiper 4t instead of a pair of rolls.
- Each wiper 46 is supported on a holder 48 pivotally mounted for swinging movements heightwise of the shoe on a stud 5d carried by the corresponding arm 25.
- a bolt 58 extends through the spring and through openings in the lugs 52 and 5, the bolt having on its lower end a head 6d which overlaps the lug Ell and having on its upper end nuts 62 which overlap the lug 52.
- Each wiper 46 is provided with an upturned inner end t@ to assist in guiding it inwardly over the shoe, and to permit it to adjust. itself to the contour of the shoe it is mounted for universal tipping movement on the holder 48.
- a spherically curved bearing member E6 mounted on a similarly curved seat on the lower face of the holder 48 and arranged to space the wiper i5 somewhat below the holder while permitting it to tip in any direction as above described.
- a pin 68 having ahead on its lower end engaging the wiper 45 extends upwardly through the wiper and the bearing member t6 and through anv enlarged opening 7i! in the holder 48, this pin being provided at its upper end with a small transverse pin 'l2 extending over and confining a spherically curved leaf spring M which rests on the upper face of the holder lill.
- the spring M accordingly tends to maintain the wiper it in a centralized position while permitting it to tip to adjust itself to the shoe.
- the wiper 45 extends into an opening i6 in the holder t8, this opening being somewhat larger than the end of the wiper to permit the wiper to tip as above describedl Relative movement of the holder #i8 and the wiper i6 in response to prese sure of the shoe on the lower face of the wiper is limited by Contact of the outer end of the wiper with the lower wall of the opening 16, so that insurance is aiforded that the wiper will apply adequate downward pressure to the margin of the upper.
- the machine is further provided with means (not shown) for lasting the heel end of the shoe and with opposite side-lasting devices for lasting the sides of the shoe from the portion operated upon by the heel-lasting means to the portion operated upon by the above-described toe-lasting means.
- Each of the opposite side-lasting devices the construction of which is substantially as disclosed in the previously mentioned Letters Patent No. 1,843,232, comprises a casing 18 (Figs. l and 5) mounted for bodily movement lengthwise of the shoe and also for swinging movement lat erally of the shoe.
- a plurality of flexible lasting straps 8B Associated with this casing and movable with it lengthwise and lateraliy of the shoe are a plurality of flexible lasting straps 8B, herein shown as three in number, arranged to extend heightwise of the last and to wipe the up- Gil per upwardly and conform it to the lateral contour of the last.
- the straps also extend outwardly over yieldingly controlled fingers 82, the outer end portions of which are shown in Fig 1, and by the action of these lingers the straps are caused to lay the margin of the upper inwardly over the insole and to press it down on the insole,
- the twoopposite sidelasting devices are arranged to act on the shoe first along the shank portion adjacent to its heelend portion and are thereafter moved lengthwise of the shoe to positions adjacent to the toe-lasting means and are then operated a second time to last the sides of the shoe in those locations while the toe wipers are maintained at the limits of their inward movements over the'shoe.
- a pair of flexible straps 84 are arranged to extend heightwise of the' shoe between the toe former I0 and portions of the upper at the sides of the last and also to extend outwardly over the upturned ends 64 of the wipers 46.
- each strap 84 is unyieldingly connected, by means of a hook 86 extending through an eyelet in the strap, to a member 88 which is part of the means for supporting the toe former I0.
- each strap 84 is connected by a hook 90, a cable 92 and a hook 94 to a spring 96 the lower end of which is connected to a bracket 98 fast on the side of the previously mentioned Vcasting 22, the cable extending over a pulley
- the straps 84 are arranged to be forced inwardly over the insole by the wipers 46, as illustrated in Fig. 4, so that these wipers act through the straps to lay the margin of the upper over the insole and to press it upon the insole.
- the straps 84 extend continuously along the upper lengthwise of the shoe into positions to be overlapped also by portions of the straps of the side-lasting devices as the latter conform the upper to the sides of the last and lay its margin inwardly over the insole, as illustrated in Fig. 5.
- the straps 84 accordingly bridge any space which there may be between the side-lasting devices and the toe-lasting means, thus insuring that the upper will be smoothly conformed to the sides of the last and that its margin will be pressed down into position to adhere to the ⁇ insole without the presence of any upstanding wrinkles.
- the straps 84 serve also to wipe the upper heightwise of the last in those locations in response to downward movement of the last, thus increasing the effectiveness of the upwiping action in the vicinity of the heelwardly extending ends of the toe former, especially if the straps are made of textile fabric as hereinbefore described. This contributes further to improved results in the shaping of the upper tightly and smoothly over the last in close conformity to the contour of the last.
- the manner of operation of the machine in so far as its operation is of interest with reference to the present invention, will now be briefly summarized:
- the operator places a last having an upper mounted thereon on the heel-end support 2 with the toe end of the upper and last resting on the toe rest 6, and while holding the upper pulled closely around the heel end of the last with his fingers releases the heel-lasting mechanism to cause it to move into operating position in the manner disclosed in Letters Patent No. 1,843,232.
- the operator then pulls the upper upwardly with his fingers at the sides of the last and releases the opposite side-lasting mechanisms to cause them to move inwardly into positions to clamp the upper against the sides of the last in thevicinity of its shank portion.
- the operator places a cement-coated insole on the bottom of the last and swings the arm I4 forwardly to carry the toe presser foot I2 into position over the bottom of the shoe, as a result of which movement of the arm the power operation of the machine is started.
- 'I'he toe presser foot and the heel ⁇ presser foot are then operated to depress the last, thus causing the side-lasting devices to wipe the upper upwardly at the sides of the last in the vicinity of the shank portion and the toe former I IJ to wipe it upwardly around the toe-end portion of the last, the straps 84 having at this time also an upwiping action on the sides of the upper in the vicinity of the heelwardly extending end portions of the toe former.
- Substantially at the end of the downward movement of the last the side-lasting devices are operated to lay the margin of the upper over the insole and to press it down on the insole along the shank portion, after which they are swung outwardly away from the shoe and the several wipers I6, I8 and 46 are operated to wipe or lay the margin'of the portion of the upper embraced by the toe former III inwardly over the insole and to press it upon the insole simultaneously with a corresponding wiping action of the heel-lasting means on the 'heel end of the upper.
- the toe presser foot I2y and the corresponding heel presser foot are raised enough to cause the margin of the upper to be pressed more firmly against these wipers bythe spring 8 under the toe rest and port 2.
- the sidelasting devices are advanced lengthwise of the shoe to positions adjacent to the toe-lasting means, after which they are again swung inwardly into engagement with the upper to conform the upper to the contour of the sides of the last and are operated to lay the margin of the upper vinwardly over the insole and to press it upon the insole.
- the Ylast is again depressed somewhat by the toe and heel presser feet to relieve the pressure of the toe wipers on the shoe, and in response to such depression of the last the side-lasting devices have an upwiping action on the sides of the upper.
- the straps 84 extend far enough along the shoe to be overlapped by the side-lasting devices in thus pressing the upper inwardly against the sides of the last and in laying its margin over the insole, as is evident by reference to Fig. 5. Any spaces between the side-lasting devices and the toe former I 0 or between them and the wipers 46 are therefore bridged by the straps 84.

17 Claims.
This invention relates to lasting machines, and is herein illustrated as applied to a machine of the same gene-ral character as disclosed in United States Letters Patent No. 1,843,232, granted on February 2, 1932, upon an application of B. Jorgensen, but modied in certain respects as further disclosed mainly in Lette-rs Patent No. 2,026,539, granted on January 7, 1936, also upon an application of B. Jorgensen. It is to be understood, however, that in various aspects the invention is not limited to machines of the type therein disclosed.
Machines of the above-mentioned type are commonly used in lasting tennis shoes or the like having uppers of textile fabric and rubber shoe bottom parts which are vulcanized while the shoes are on their lasts. Such a machine includes a toe former which extends around the toe end and along portions of the sides of the upper and wipes the upper height-wise of the last, overlaying members which lay o-r wipe the margin of the portions of the upper embraced by the toe former inwardly over an insole on the last into position toadhere to the insole, and ,side-lasting devices 525 which conform the upper to the sides of the last and lay its margin inwardly over the insole first along the shank portion of the shoe and thereafter in locations nearer the toe end of the shoe adjacent to the toe former and the above-mentioned overlaying members. An object of the present invention is to provide a construction such as to produce improved results along the sides of the forepart, and more particularly, in one aspect, to afford better insurance than heretofore against the formation of any upstanding wrinkles in the margin of the upper over the insole between the above-mentioned overlaying members and the side-lasting devices. Treatment which shoes of the above-mentioned type ordi- -sn narily receive between the lasting operation and the laying of the outsole render it especially desirable that no .such wrinkles be present. For the purposes in vie-w the machine herein shown is provided with novel means constructed and arf. ranged to bridge any space that there may be along the margin of the upper between the abovementioned overlaying members and' the sidelasting devices and to be pressed upon the margin of the upper by those members and devices. As .wi illustrated, nexible straps are arranged to extend heightwise of the shoe between the toe former and portions of the sides of the upper and to eX- tend also into positions where they are overlapped and forced inwardly over the insole against the margin of the upper by the above-mentioned overlaying members and are thereafter overlapped and pressed upon the margin of the upper also by the side-lasting devices. Springs connected tothe straps are arranged to hold them taut while permitting them thus to be forced inwardly over the insole. Since the straps in the construction shown extend between the toe former and portions of the sides of the upper, they cooperate with the toe form-er in wiping the upper heightwise of the last and, in fact, increase the effectiveness of the wiping action on the sides of the upper where they are located, the straps preferably being formed of textile fabric, such as canvas, adapted to act with eiective friction on the fabric upper as well as to act effectively to press the margin of the upper rrnly on the insole. In the construction shown the straps are also arranged to extend beyond the toe former along the sides ofthe upper and to be overlapped by the side-lasting devices in conforming the upper to the sides of the last, thus affording increased insurance against the formation of any wrinkles in the upper opposite the sides of the forepart of the last.
The above and other features of the invention,
including various novel details of construction and y combinations of parts, will now be more particularly described with reference to the accompanying drawings and thereafter pointed out in the claims.

Fig. 5 is a plan view, with parts broken away, illustrating conditions at the same stage in the operation of the machine as in Fig. 4.
. As more fully disclosed in the above-mentioned Letters Patent, a last with an upper thereon is mounted at its heel end on a support 2 provided with a pin 4 which` extends into the spindle hole in the last, the support being yeldingly depressible with the last and shoe against the resistance of a spring V(not shown). At its toe end the last is supported on an upper-engaging toe rest 6 (Figs. 3 and 4) yieldingly depressible against the resistance of a spring 8. Arranged to extend continuously around the toe end and along portions of the sides of the shoe is a toe former comprising a band l which may be made of comparatively hard leather or other material suitable for wiping the upper effectively heightwise of the last in response to depressionof the last. Such depression of the last is effected in the power operation of the machine by a toe presser foot l2 arranged to engage the toe end of an insole on the last and by a heel presser foot (not shown) which engages the heel end of the insole. The toe presser foot I2 is supported by an arm I4, a portion of which is shown in Fig. 1, this arm being swung forwardly by the operator to a position over the shoe and being then moved down- Wardly by power to depress the shoe, the arm having also thereon means which need not be particularly described for controlling the margin vofthe toe end of the upper in the lasting operation. The toe former or band i@ is supported and vcontrolled by means such as disclosed in Letters Patent No. 2,026,539, whereby it is held yieldingly in effective wiping engagement with the upper during the depression of the last but is permitted to yield in outward directions in response to pressure of the last and upper thereon while .maintaining its conformity to the contour ofthe last.
After the wiping of the upper heightwise of the last by the toe former lil as above described, the margin of the portion of the upper embraced by the toe former is laid or wiped inwardly over the Vthe last-mentioned Letters Patent.
.insole into position to adhere to the insole by a plurality of wipers hereinafter sometimes referred to as overlaying members. The construc tion of these wipers and of the means for operating them is, for the most part, substantially as disclosed in Letters Patent No, 2,026,539 The wipers comprise a pair of end wiper plates i6 (Fig. 2), and a pair of side wiper plates i8 for wiping the upper inwardly along the sides only oi the toe beyond the end plates. The side plates i8 are comparatively thin plates which are fast on arms 2li, only one of which is shown in Fig. 2, these arms being pivotally mounted for swinging movements laterally of the shoe on a casting 22 winch supports the wipers and their operating mechanism. The end plates i6 are connected together by a pin 26 for swinging movements laterally of the shoe, and in operation they are also advanced bodily lengthwise of the shoe relatively to the side plates It with portions of them overlapping these side plates. The end plates I6 are supported by a rack bar Z which is slidingly movable in the casting 22 and is operated thus to advance them lengthwise of the shoe The end plates and the side plates I8 are, closed laterally of the shoe by rack bars 28 also slidingly movable in the casting 22, Each of these rack bars is adjustably connected to a slide 3U which is connected by a link 32 to a lever Sli pivoted at 36 on the casting 22, the lever 34 being provided with a pin 38 arranged to act through a link 4t to close the corresponding end wiper plate It. Each lever 3Q serves also to operate the corresponding side wiper plate it by swinging the arm 20, the lever acting on the arm through a sliding connection 42 between the lever and the arm, as fully disclosed in The side wiper plates I3 are positioned initially far enough apart to provide ample room between them for shoes of diierent widths, and the links 4B are provided with slots i4 to receive the pins 38 and to delay the beginning of the closing movements of the end plates I until the side plates have been moved into substantially as close relation to the shoe as the end plates.
For laying the margin of the upper inwardlf,7 over the insole in locations immediately beyond the ends of the side plates I8 the machine herein shown is provided with devices substantially like those shown in Letters Patent No. 2,026,539, ex-
cept that each of these devices comprises a wiper 4t instead of a pair of rolls. Each wiper 46 is supported on a holder 48 pivotally mounted for swinging movements heightwise of the shoe on a stud 5d carried by the corresponding arm 25. Mounted between a lug 52 on the holder 48 and a lug 5t on the arm 2i] is a spring 55 which tends to swing the holder about the stud 5B in the direction to depress that portion of the wiper 45 which acts on the shoe, the spring being yieldable in response to upward wedging action of the shoe on that portion of the wiper. To limit movement of the holder 4S by the spring 56 a bolt 58 extends through the spring and through openings in the lugs 52 and 5, the bolt having on its lower end a head 6d which overlaps the lug Ell and having on its upper end nuts 62 which overlap the lug 52. Each wiper 46 is provided with an upturned inner end t@ to assist in guiding it inwardly over the shoe, and to permit it to adjust. itself to the contour of the shoe it is mounted for universal tipping movement on the holder 48. For this purpose there is provided a spherically curved bearing member E6 mounted on a similarly curved seat on the lower face of the holder 48 and arranged to space the wiper i5 somewhat below the holder while permitting it to tip in any direction as above described. A pin 68 having ahead on its lower end engaging the wiper 45 extends upwardly through the wiper and the bearing member t6 and through anv enlarged opening 7i! in the holder 48, this pin being provided at its upper end with a small transverse pin 'l2 extending over and confining a spherically curved leaf spring M which rests on the upper face of the holder lill. The spring M accordingly tends to maintain the wiper it in a centralized position while permitting it to tip to adjust itself to the shoe. At its outer end the wiper 45 extends into an opening i6 in the holder t8, this opening being somewhat larger than the end of the wiper to permit the wiper to tip as above describedl Relative movement of the holder #i8 and the wiper i6 in response to prese sure of the shoe on the lower face of the wiper is limited by Contact of the outer end of the wiper with the lower wall of the opening 16, so that insurance is aiforded that the wiper will apply adequate downward pressure to the margin of the upper.
The machine is further provided with means (not shown) for lasting the heel end of the shoe and with opposite side-lasting devices for lasting the sides of the shoe from the portion operated upon by the heel-lasting means to the portion operated upon by the above-described toe-lasting means. Each of the opposite side-lasting devices, the construction of which is substantially as disclosed in the previously mentioned Letters Patent No. 1,843,232, comprises a casing 18 (Figs. l and 5) mounted for bodily movement lengthwise of the shoe and also for swinging movement lat erally of the shoe. Associated with this casing and movable with it lengthwise and lateraliy of the shoe are a plurality of flexible lasting straps 8B, herein shown as three in number, arranged to extend heightwise of the last and to wipe the up- Gil per upwardly and conform it to the lateral contour of the last. The straps also extend outwardly over yieldingly controlled fingers 82, the outer end portions of which are shown in Fig 1, and by the action of these lingers the straps are caused to lay the margin of the upper inwardly over the insole and to press it down on the insole, In the operation of the machine, as disclosed in the lastmentioned Letters Patent, the twoopposite sidelasting devices are arranged to act on the shoe first along the shank portion adjacent to its heelend portion and are thereafter moved lengthwise of the shoe to positions adjacent to the toe-lasting means and are then operated a second time to last the sides of the shoe in those locations while the toe wipers are maintained at the limits of their inward movements over the'shoe.
For the purposes of the present invention, a pair of flexible straps 84, preferably made of canvas or other suitable textile fabric, are arranged to extend heightwise of the' shoe between the toe former I0 and portions of the upper at the sides of the last and also to extend outwardly over the upturned ends 64 of the wipers 46. At its lower end each strap 84 is unyieldingly connected, by means of a hook 86 extending through an eyelet in the strap, to a member 88 which is part of the means for supporting the toe former I0. At the end of its outwardly extending portion each strap 84 is connected by a hook 90, a cable 92 and a hook 94 to a spring 96 the lower end of which is connected to a bracket 98 fast on the side of the previously mentioned Vcasting 22, the cable extending over a pulley |08 mounted on a bracket |02 also supported by the casting 22. The straps 84 are arranged to be forced inwardly over the insole by the wipers 46, as illustrated in Fig. 4, so that these wipers act through the straps to lay the margin of the upper over the insole and to press it upon the insole. The straps 84 extend continuously along the upper lengthwise of the shoe into positions to be overlapped also by portions of the straps of the side-lasting devices as the latter conform the upper to the sides of the last and lay its margin inwardly over the insole, as illustrated in Fig. 5. The straps 84 accordingly bridge any space which there may be between the side-lasting devices and the toe-lasting means, thus insuring that the upper will be smoothly conformed to the sides of the last and that its margin will be pressed down into position to adhere to the `insole without the presence of any upstanding wrinkles. It will further be evident that, positioned as they are between the toe former and portions of the sides of the upper, the straps 84 serve also to wipe the upper heightwise of the last in those locations in response to downward movement of the last, thus increasing the effectiveness of the upwiping action in the vicinity of the heelwardly extending ends of the toe former, especially if the straps are made of textile fabric as hereinbefore described. This contributes further to improved results in the shaping of the upper tightly and smoothly over the last in close conformity to the contour of the last.
The manner of operation of the machine, in so far as its operation is of interest with reference to the present invention, will now be briefly summarized: The operator places a last having an upper mounted thereon on the heel-end support 2 with the toe end of the upper and last resting on the toe rest 6, and while holding the upper pulled closely around the heel end of the last with his fingers releases the heel-lasting mechanism to cause it to move into operating position in the manner disclosed in Letters Patent No. 1,843,232. The operator then pulls the upper upwardly with his fingers at the sides of the last and releases the opposite side-lasting mechanisms to cause them to move inwardly into positions to clamp the upper against the sides of the last in thevicinity of its shank portion. Thereafter the operator places a cement-coated insole on the bottom of the last and swings the arm I4 forwardly to carry the toe presser foot I2 into position over the bottom of the shoe, as a result of which movement of the arm the power operation of the machine is started. 'I'he toe presser foot and the heel `presser foot are then operated to depress the last, thus causing the side-lasting devices to wipe the upper upwardly at the sides of the last in the vicinity of the shank portion and the toe former I IJ to wipe it upwardly around the toe-end portion of the last, the straps 84 having at this time also an upwiping action on the sides of the upper in the vicinity of the heelwardly extending end portions of the toe former. Substantially at the end of the downward movement of the last the side-lasting devices are operated to lay the margin of the upper over the insole and to press it down on the insole along the shank portion, after which they are swung outwardly away from the shoe and the several wipers I6, I8 and 46 are operated to wipe or lay the margin'of the portion of the upper embraced by the toe former III inwardly over the insole and to press it upon the insole simultaneously with a corresponding wiping action of the heel-lasting means on the 'heel end of the upper. At this time the straps 84, which are overlapped by the wipers 46, are forced inwardly over the insole bythese wipers against the resistance of the springs 96, so that the wipers 46 act through the straps to lay the upper over and press it upon the insole. Near the end of the overlaying movements of the wipers I6, I8 and 46 the toe presser foot I2y and the corresponding heel presser foot are raised enough to cause the margin of the upper to be pressed more firmly against these wipers bythe spring 8 under the toe rest and port 2.' Substantially at the same time the sidelasting devices are advanced lengthwise of the shoe to positions adjacent to the toe-lasting means, after which they are again swung inwardly into engagement with the upper to conform the upper to the contour of the sides of the last and are operated to lay the margin of the upper vinwardly over the insole and to press it upon the insole. As the side-lasting devices engage the sides of the shoe in this second operation the Ylast is again depressed somewhat by the toe and heel presser feet to relieve the pressure of the toe wipers on the shoe, and in response to such depression of the last the side-lasting devices have an upwiping action on the sides of the upper. The straps 84 extend far enough along the shoe to be overlapped by the side-lasting devices in thus pressing the upper inwardly against the sides of the last and in laying its margin over the insole, as is evident by reference to Fig. 5. Any spaces between the side-lasting devices and the toe former I 0 or between them and the wipers 46 are therefore bridged by the straps 84. thus insuring that the upper will be smoothly conformed to the sides of the last and that no upstanding wrinkles will be formed in the mar- `the corresponding spring under the heel-end supgin of the upper between the side-lasting devices i and the wipers. After the second operation of the side-lasting devices on thesho'e the partsV of the machine are returned to their startingv positions, lthe shoe being released to permit its removal from the machine. i
