3o anims. .(01. 12-14) Y This invention relatesto lasting machines, and

in some aspects more particularly to toe-end lasting means. The invention is herein illustrated as embodied in a lasting machine of the 5-j bed type. In the manufacture of various kinds of shoes, itis the common practice to subject the upper to a pulling-over operation whereby it is ten-Y sioned or stretched lengthwise'of the last and is also shaped in' general conformity to the contour` of the forepart of the last, and thereafter to present the shoe to a ldifferent machine for the toe-lasting operation. In the toe-lasting operation it is usually the practice, after removing' l5 one or more of the pulling-over tacks, to sub-V ject the upper around.v the toe end of the last to repeated upwiping operations to conform it tightly to the contour of the last before laying' itsy marginal portion around the toe end inwardly over an insole or other shoe bottom part hereinafter frequently referred to generically as a sole The upwiping operation is usually performed by means of end-embracing wipers which are shaped to conform substantially to the contour of the toe-end of the last. While the use of such wipers has, for .the most part proved to be vsatisfactory it has been found, under some conditionsof work, particularly Where the heightwiseV contour of the toe end of the last is such" as to render it difcult for the wipers to apply'. effective upwiping pressure to the upper along the sides of the toe end, that the upper h asjnotll been conformed as tightly to the contour of thev last in those locations as is desirable.

In view of the above,` theppresent invention,v

in one importantV aspect has in View the provision, in combination with means for laying they marginal portionpf an upper inwardly over l'a sole on a last, of improvedL means for conforming` 40 the upper tightly to the contour of the last along the opposite sides of the toe end prior to' the overlaying operation. In the use of aV machine of the type herein shown in which the shoe is held firmly in position for the lasting operation by a heel support, a toe restk and aholddown, the toe rest is utilized to clamp the shoe against the holddown and'to press the upper into conformity to the contour of the top of the fore-V part* of the last, and novel upwiping devices are provided for wiping the upper at the oppositel sides of the toe end toward thejedge ofthe shoe bottom and for holding it clamped against the;

lateral faces of the last'duringr the overlaying,

v operation.-Y In Vthe illustrated construction,i`tl[1e y 55 toe restcomprises a resilient pad whichis shaped` approximately toconformV to the contour of the top of the forepart of the shoe and is mounted on a holder which is controlledl by a spring yieldable in response to the upward movement of an operating member, used as heretofore in kma- 5 chines of the type herein shown to elevate the toe rest. The upwiping devices comprise' wiping members which are arranged to engage the upper along the sides of the toe end of the last substantially from the tip line forwardly to theV 10 corners of the toe end'and are connected to rods which ar-e slidable vertically through guide sleeves pivotally connected for swinging movements about axes extending lengthwise Vof the shoe to the above-mentioned holder, the rods l5' being connected at their 'lower ends to .armsv pivotally connected `to the .operating member. Thus as the toe rest is pressed yieldingly against the shoeA to' clamp the shoe against the holddown` it conforms the 'upper to the contour of thev top ,Y o f the forepart of the last, and the wiping mem-' bers engage and wipe heightwise of the last at the opposite sides of the toe end portions of the upper located nearer the edge of the last bottom than the portion engaged by the toe rest.

Preferably, and as'herein shown, there fis also provided means for adjusting the wiping mem-k bers toward or from each other widthwise of y the shoe by Varying the initial positions ofl the above-mentioned arms, and means arranged to 3-0l engage and to swing the arms in directions to force the .wiping members yieldingly against thel upper substantially at the beginning of their upwiping movements and for holding them in cl'ampingrelation to the upper during the over- 35' laying operation.

For bestresultsin the upper shaping or conforming operation itis desirable that the pressure of the toe rest be'applied to'the shoe in such manner as to avoidany danger of damage 40" to the 'upper by excessive pressure of 'the toe rest on the upper in any location and that the wiping members in theupwiping operation move in paths substantiallyV normal to the plane of the bottom of theforepart'of the shoe in orderto conform the upper tightly and smoothly to the contour of the lateral faces of the last at the toe end. For the purpose in view, the toe rest upon which the wiping members are mounted for movements heightwise of the shoe '50' is so constructed as to adjust itself to each shoe about an axisextending laterally of the shoe and located substantially in the plane of the bottom of lthe forepart of the shoe. V'In the construction shown, the holder, to which "the guiding means or sleeves for the wiping members are pivotally connected, is supported by a member provided with an arcuate slot concentric with such axis and in which there are mounted rolls carried by the holder. Thus the toe rest is permitted to adjust itself readily to` each shoe in response to pressure of the shoe thereon and to position the wiping members for movements in paths substantially normal to the plane of the bottom of the forepart of the shoe.

The above and other features of the invention, including various novel details of construction and combinations of parts, will now be more particularly described by reference to the accompanying drawings and pointed out in the claims, Y

The invention is herein illustrated as applied to a bed lasting machine of a well-known type features of the general organization of which are disclosed in various United States Letters Patent including especially Letters Patent No. 1,018,477, granted on February 27, 1912, and No. 1,373,482, granted on April 5, 1921, both upon applications of Matthias Brock. Only such features of the general organization therefore as it is necessary to refer to for an understanding of the invention are herein shownand will be described in detail.

Machines of this .type includeheel lasting mechanism and toe-lasting mechanism between which the shoe and last are supported at the heel end by aljack I0 and at the toe Lend by a toe post I2. prises a wiper head I4 which is adjustable in various ways lengthwise and laterally Vof theshoe with provision for tipping movement to position the toe-embracing wipers I6 substantially parallel to the plane of the forepart of the shoe bottom, the wipers IB being operated by a hand lever I8 (Fig. 1).l The wiper head I4 is carried by a support 20 which is guided for vertical movements in the frame 22 of the machine and is connected by a link 24 to a treadle 26 whereby the operator is enabled to raise or lower the wipers as desired. The toe post I2 is supported by a'member 28 which is adjustable vertically by means of a hand wheel 30, The heel lasting mechanism is carried by a head 32 which is mounted for movement lengthwise of the shoe toward or from a denite operative position in which position it is locked by a latch 34, Fig. 1. The jack Ill'is fast to a slide, not herein shown, which is movable, by means of a hand wheel 38 and connections The toe-lasting mechanism com-A therefrom to the slide, against the tension of a return spring, in a direction to draw the shoe firmly back into the end-embracing band 3l of the heel lasting mechanism, means (not shown) being provided for locking the hand Wheel to hold the slide against return movement. Thereafter, the machine is started by movement of a knee lever 42, whereupon the heel band is closed about the heel end of the shoe and the member 28 and the toe post I2 are moved upwardly by the action of a cam 44 on a lever 48 -pivotally connected to a slide 48 to which the -member 28 is adjustably secured. The machine is alsov provided with a holddown 38 which is swung forwardly and downwardly and is depressed by a treadle 4U into position to engage the bottom ofthe forepart of the shoe. The holddown 38 is in many respects similar to the disclosure l of Letters Patent No. 1,188,403, granted on June 27, 1916 upon an application of L. M. Brown, and comprises a projection 50 onthe forward end of an arm 52 and a holddown finger 54 carried bya block 56 adjustably secured toa spindle 58 of a member (not shown) which is rotatably mounted in the forward end of the arm 52 and is connected to a torsion spring againstthe resistance of which the finger 54. may move relatively to the projection 50 to adapt itself to the spring or lengthwise inclination of the bottom of the forepart of the shoe being operated upon. The arm 52 is slidingly movable lengthwise in a holder 6D supported on a vertical rod 62. This supporting means and its operating mechanism, in the machine herein shown, are of substantially the same construction as means provided heretofore in machines of the illustrated type for supporting a holddown member and for pressing the member upon the shoe bottom, as disclosed in United States Letters Patent No. 1,120,822, granted on December 15, 1914, on an application of E. L. Keyes.

ForV purposes of this invention, there is mounted on the toe post I2 a toe-supporting device or toe rest which, as herein shown, comprises a holder 64 (Figs. 2, 3 and 4) having mounted thereon a flexible resilient pad 66, preferably of rubber, for engaging the shoe, the padv being shaped approximately to conform to the top of the forepart of the shoe. The holder 64 is mounted on a support 68 which has a'depending hollow stem 10 (Figs. 3 and 4) slidingly mounted in a vertical central bore in the post I2. The post I2 is freely slidable vertically through a guide sleeve 'I2 (Fig. 1) on a bar 'I4 that is slidable horizontally on the under side of the toe lasting head, as usual, and as appears more in detail in said prior Patent'No. 1,378,482. Threaded into the lower end of the toe post I2 is an adjusting screw 'I6 which rests on the member 2B and by means of which the initial heightwise position of the toe rest may be varied.

The toe rest is pressed firmly against the shoe in the upward movement of the supporting member 28 and the post I2 by a spring 18 (Figs. 3 and 4) engaging the lower end face of the hollow stem 'I0 within the central bore in the post I2. To limit movement of the toe rest in one direction when there is no shoe in the machine there is provided a pin which extends through vertical slots 82 in the hollow stem 10 and engages the post I2 at the upper ends of vertical slots'84 in the post (Fig. 6). The pin 80 extends also through apertures in a s1eeve'86 which surrounds the upper end portion of the toe post I2 and is: slidableu vertically thereon. A f spring `88 within the depending :hollow stem, 10 Y of the support-.68 engages; the pin .80. Pivotally connected to the post |2;;v one on each sideofthe shoe,4 are arms 90. to the'upperV ends of which are pivotally connected guide blocks 92 for rods 94. The rods 94 extend upwardly throughguide:

sleeves 96.which. are pivotally connected'at 98 for' swinging rmovements about Aaxes .extending lengthwise of the shoe to laterally extending ears on the .holdert64, andpivotally connected to the vupper ends of the rods 94 are wiping members |02 for engaging the upper'at the sides of the lastabove the pad 66l and for wiping the upper upwardly toward the edgefof. the sole. The members. |02, which are preferably made of rubber, are securedto blocks |04 pivotally connected to the upper ends of .the rods 94. As shown in Figs. V1 and 2,'the wiping members |02 extendlengthwise ofthe shoe substantially from the tip line (if the shoe has a toe tip) forwardly to the corners of the toe end and have plane upper. surfaces |06 which are substantially parallel to the axes 98 of the guide 'sleeves 9G.

the rods 94 and the guide sleeves 96 are swung' about the axes 98 of the guide sleeves in directions to move the wiping members |02 outwardly away from each other, and that by adjusting the screws A||4 vthe initially spaced apart positions of the wiping members may bel varied.

Preferably the .wiping members |02 will be adjusted-laterally ofthe last so as to engage the upper initially at the opposite sides of the last just above the pad 66; I f Y` f By reference toFig.4f it will be seen that the sleeve- 86 iscut away to vpermit the arms 90 to swing vinwardly toward each other. f Formed upon the sleeve 86 are cam surfaces ||6 which are arranged to` ybe engaged by the rounded upper ends of the arms 90 substantiallyat the beginning of the upward movement ofthe'toe post --|2. As the arms 90 are'moved upwardlyv to impart to the wiping members |02 through the collars |08 and rods'94- their upwiping movements they are also swung outwardly by the action offthe cams ||6 on theirrounded upper ends. Outward swinging movement of the arms 90 causes the wiping members |02 tor be pressed imore firmly against the shoe, the construction being such that in the' upward movement of the toe" post I2, when the spring 'I8 is compressed in response to the pressureof the shoe onthe pad 66, the armsl 90 are moved into engagement with the cams VI| 6 onv the' sleeve 86 which is Yheld against movement relatively tothe support 68 by the action of the spring 88 on the pin 80 carried by the sleeve.' Thereafter in response to resistance of the shoe to the pressure applied by the'fwiping members |02 the spring 88 yields and the sleeve Iltisv moved upwardly with theV arms-'90, thespring 88 acting then to hold the arms 90- in such positions asV to-prevent any relaxing of the pressureof the wiping members |02 on the upper. 'f i' j that plane.

'i In order that the wiping members |02.will movelupwardly in paths substantially normal tothe'plane of the bottom of the forepart of .the shoe,the toe rest, to which the guide' sleeves 96 for .the rodsv 94 of .the wiping members are pivotally connected, is soconstructed as to permit itto adjust itself to each shoe about an axis extendinglaterally of the shoe and located substantially -in the plane ofthe bottom ofthe forepart of the'shoe. As herein shown, the support 68 has an arcuate slot ||81 (Fig. 2) formed therein concentric with such axis and in which there are mounted rolls |20 carried by the holder 64 of the toe rest. The holder 64 has a pair oi downwardly extending flanges |22 which engage the opposite side faces of the support 68, and supported by these flanges Yare pins I 24 upon which the rolls |20 are rotatably mounted Set screws |26 threaded into one of the flanges and engaging the pins |24 act to hold the pins against endwise movement. The holder 64 is thus mounted on the support 68 to turn freely about an axis extending laterally of the shoe and' located substantially lin the plane of the bottom of the forepart of the shoe to adjust itself to each shoe. As the holder 64 thus adjusts itself to the shoe'the guide sleeves 96V for the rods 94 are also adjusted about the same axis to position the rods 94 and the wiping members |02 for-upward movements in paths substantially normal to the plane of the bottom of the forepart'of the shoe. To permit the rods 94 to be thus adjusted relatively to the guide blocks 92, these blocks are provided with elongated slots |28 (Figs.`2 and 5) through which the rods ed extend, the top and bottom faces of the blocks 92 being preferably also concentric with the axis about which the holder 6ft is adjustable.

In the operation of the machine, briefly summarized, after a shoe is positioned at the desired height upon the jack I8 and the toe rest, the -heel-end-lasting head 32 is moved to the left into operative position and the hand wheel 36 is operated to force the shoe rearwardly into the heel band 31. The holddown 38 is then swung forwardly and downwardly by the operator and is depressed by the treadle 40 into position to engage the bottom of the forepart of the-shoe'. It will be understood that as the shoe is placed on the toe rest by the operator the `toe rest will adjust itself 'to the shoefabout an axis extending laterally of the shoe and located substantially inthe plane of the Ibottom o! the forepart of the shoe and the wiping members |02 will thus be positioned for upward movements in paths substantially normal to Thereafter the machine is started by movement of the knee lever 42, whereupon the heel band is closed about the heel end of the shoe and the toe post l2 is elevated by upward movement of the member 28 and slide iB-in response to the action of the cam 44 on the arm 46. In responseto the upward movement of the toe post the shoe is clamped yield-l ingly against the holddown 38 and the wiping members |02 are carried nearly to the edge of the shoe bottom. As the shoe" is thus clamped yieldingly against theholddown the upper at the top of the forepart is'pressed intoconformity to the contour of the top and sidesof theltoe end of the last by the pad 66 and wipingmembers |02, the wipers I6 are raised by the treadle. 26 substantially to the edge of the sole `and are advanced and closed above the wipers |02until their inner edges are close to the upper. The operator then with the ngers of his right hand or with a suitable spreading tool, spreads the,

margin of the upper at the. extremegtoe end of the last outwardly over the-wipers VI6 and while holding the margin of theupper thus pressed against the wipers further raises the wipers, thereby tensioning this portion .of the;

upper, heightwise of the last, and. by means of the hand lever I8 advances and closes the wipers to wipe the marginal portion of the upper around the toe end and along the sides ofl the toe end inwardly over the sole. It will beunderstood that Iby depressing the right-hand portion of the treadle 26 the operator may increase the pressure of the wipers I6 on the upper during their inward movements and that after the wipers have been advanced andfclosed, they may be retracted and again advanced and closed to wipe the marginal portion of the upperrrover the sole a second time. It will be understood also that prior to the second overwiping operation the wipers i6 may be retracted farenough to permit the operator to trim the lining andV box toe back nearly to the edge of the sole'and to apply cement to the margin of the upper and to the sole to hold the upper in lasted position after it has been again wiped inwardly over the sole, or the marginal portion of the upper may be fastened in lasted position by tacks at the end of the overlaying operation. The different parts of the lasting mechanism are thenv returned to their starting positions and the shoe removed from the machine.

While the invention is illustrated by reference to the manufacture of shoes of that type in which the margin of the upper for its entire width is lasted in substantially parallel relation to the outer or bottom face of a sole it will be understood that the invention is not limited to the manufacture of shoes of that particular` type.
