20 Claims.

Letters Patent No. 1,583,044, granted on'May 4;

1926, upon an application filed in the name of C. H. Hoyt, for lasting the heel ends if shoes. It is to be understood, however, that in its more general aspects the invention is not-limited to machines of that type 1101' to machines. l

,In machines of the above-mentioned type the margin of the heel end of the upper is wiped heel-end lasting inwardly over a shoe bottom part such asa sole or insole, mounted on a last, by wipers which are mounted for bodilyadvancing movement lengthwise of the shoe and swinging or closing movements laterally of the shoe to wipe the upper inwardly substantially the same 'distancelirom the edge of the shoe bottom both at the end and at'the sides of the, heel seat. In such machines there is provided means for adjusting the wipers toward or from each other to varytheir initial open positions to accommodate shoes of different sizes, such an adjustment correspondinglyvarying the limits of the closing movementsofthe wipers as required by the different sizes. Variation in the limits of the closing movements is also sometimes required for the best results by differences in style, especially difierencesinvolving wide variations in the widths of the shank portions of the shoes. It has been found,howev'er, thatif the wipers are positioned initiallynear enough together to produce the best results at the end of the wipe at the forward portion of the heel seat in operating, for example, on shoes having very narrow shank portions, they may not be in the bestpositions to begin the overwiping operation'at other portions of theheel seat.

- In view of the above, an object of the present invention is to provideimproved wiper-operating means so constructed that the limits of the closing movements of the wipers may be varied without altering substantially their positions relatively to each other at the: beginning of their closing movements. In the illustrated construction,.as in that disclosed in the above-mentioned Letters Patent, the wipers are advanced by'an' operating member which is mounted for rectilinear movements in directions lengthwiseqoflthe shoe, and connected to this member are slides movable laterally of the shoe at its opposite sides for imparting to the wipers their closing movements in predetermined time relation to their advancing movement. The wipers are connectedto the closing slides by plates having guide slots therein extending in directions lengthwise of the shoe and in which are movable rolls carried by the wipers, the plates thus acting to guide the wipers in their operative movements. For varying 'the limits of the closing movements of the wipers the plates, in the construction shown, areadjustablerelatively to the closing slides to positions-in which their guide slots are in angular relation to the direction of the movement of the wipers lengthwise of the shoe, so that more or lessclos-r ing movement is imparted to'the wipers in re-- sponse to their movement lengthwise of theshoe in addition to that derived from the movements of the closing slides. Provision is accordingly afforded for varying the amount and therefore the limits of the closing movements of the wipers, the construction being such that the initialpositions of the wipers are substantially unaffected by the adjustment of the plates on the, closing slides. Preferably, and as shown, separate means. is provided for adjusting each guide plate rela: tively to its closing slide to permit the amount of closing movement imparted to each wipert be varied independently of the amount of closing movement imparted to the other wiper. This permits an adjustment such that the wiper oper-. ating at the inner side of a rightor a left shoe will receive a greater closing movement than the wiper at the outer side, as may be required forthe best results in operating on some styles of shoes.

In machines of the type illustrated the i in the heel-end lasting operation, is clamped around the heel end of the'last by a heel bandwhich for best results should apply substantially; uniform pressure to the upper atjthe opposite sides of the shoe and should positionvthe; shoe with the median line of its heel-end portionsubstantially in alinement with the path of the meeting point of the wiper edges as the wipers advance lengthwise of the shoe. To permit the proper positioning of each shoe by the band and the positioning of the shoe also in proper relation to theplane of the wipers, the invention provides,

as'a further feature, improved "shoe-supporting means arranged to permit bodily movement of the shoe laterally to centralize the heel end of the shoe relatively to the wipers while permitting theshoe also to be tipped relatively to the wipers to position the heel seat in proper relation tothe plane of the wipers without anysubstantialplatr eral displacement of the heel end of the shoe rel-. atively to the band. The shoe is thus supported in proper relation to-the heel band andto-the wipers notwithstanding such variations as there may be in the angular relation of different spindle holes to the bottom faces of different lasts or variations in the locations of difierent spindle holes laterally of the heel ends of difierent lasts. 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. In the drawings, Fig. 1 is a view, partly in plan and partlyin section of a portion of a heel-end lasting machine in which the present invention is embodied;

Fig. 4 is a section on the line IV-IV of Fig. l. 'I'heinvention, as previously stated, is herein illustrated as embodied in a machine of the same general type as that disclosed in the above-mentioned Letters Patent, portions of the machine shown being constructed as further disclosed in Letters Patent No. 1,852,015, granted April 5, 1932, on an application filed in my name. Accordingly, only such portions of the machine as it is necessary to refer to for an understanding of the in- Vention will be described herein in detail. Ma'- chines of this type are designed especially for the shaping of shoe upper materials at (herein referred to inclusively as the upper) about the heel end of a last I) and include means for wiping the margin of the upper inwardly'over a sole or insole c on the last and means for driving a plurality of fastenings such as tacks to fasten the margin of the upper in overwiped position. Such machines comprise a shoe support or jack, hereinafter more particularly referred to, upon which the shoe is supported and by swinging movement of which the shoe is positioned with its heel end within a heel-embracing band 1 Hi. This heel band is supported in the machine and is closed about the heel end of the shoe in the power operation of the machine by mechanism fully shown and described in the above-mentioned Letters Patent No. 1,583,044, and which need not be described herein. In the course of the operation of the machine the shoe is engaged on the heel seat by a holddown member or presser foot It also automatically controlled as disclosed in the above mentioned Letters Patent No. 1,583,044, and cooperating with the jack to determine the heightwise position of the shoe relatively to the wiping and fastening mechanism of the machine. For wiping the margin of the upper inwardly over the sole about the heel end of the last the machine is provided with a pair of wipers M and I6 mounted for swinging movements about an axis located at the meeting point of the wiping edges of the wipers. The wipers I 4 and i6 are maintained in proper relation to each other and are guided for swinging movements about their common axis by means which is substantially the same as that fully shown and described in the prior Letters Patent No. 1,852,015. As more fully shown in said Letters Patent, the wipers are mounted on a wiper holder comprising a slide it which is mounted in a guideway in the head of the machine for rectilinear movements length wise of the shoe to advance and retract the wipers. The slide it is provided at its rear end with a cylindrical projection 20 mounted in a socket in the head to assist in guiding it. The slide 88 is operated to impart to the wipers Hi and it; their movements lengthwise of the shoe by means which is substantially the same as that shown and described in the above mentioned Letters Patent No. 1,583,044.

For imparting to wipers l4 and i6 swinging or closing movements in automatically determined time relation to their advancing movement lengthwise of the shoe, in general similarity to the organization disclosed in the prior Letters Patent 'No. 1,852,015, there are mounted in guideways in the opposite sides of the head of the machine slides 22 (Fig. 1), one for each of the wipers, and each slide has connected thereto by means of a screw 24 a member or plate 26, hereinafter more particularly referred to, in which there is formed a slot 28 to receive a roll 30 carried by the adjacent wiper. A cover plate 32 (Fig. 4) overlaps the slides 22 and is provided with slots 34 in which upstanding portions of the screws 24 are movable. For imparting operative movements to the slides 22 the wiper-supporting slide 18 carries a member 36 provided on each of its opposite sides with a series of rack teeth 38 in engagement with a curved rack 40 formed'on one end of a lever 42 which is pivotally mounted at M on the head of the machine. On the opposite end of the lever 42 is a curved rack 46 which engages and operates a pinion 48 in engagement with teeth formed on a rack member 50 secured adjustably by a screw 52 in a recess in the slide 22. It will thus be seen that as the wiper-supporting slide [8 moves forward to advance the wipers lengthwise of the shoe the slides 22 through the connections described are moved inwardly toward the shoe to impart closing movements to the wipers and as the slide I8 is retracted the slides 22 are likewise retracted to open the wipers. It will be understood that by the elongated slots 28 and the rolls 30 operative connections are maintained between the slides 22 and the wipers in all positions of the wipers lengthwise of-the shoe.

Similarly to the disclosure of the prior Letters Patent, the connections between the member 36 and the slide H? are such that by adjusting this member relatively to the slide the wipers may be adjusted in unison about the axis of their swinging movements to position them in proper relation to each other for operating on shoes of different sizes. For this purpose the member 38' is mounted in a recess in the slide 58 with provision for limited movementslengthwise of the shoe and is provided with a pair of downwardly extending lugs 54 (Fig. 1) which fit within recesses formed in a block 50 also movable lengthwise of the slide I 8 and provided with a bore having screw threads engaged by the threads of a shaft 53. The shaft 58 is rotatably mounted at its opposite ends in bearing blocks 69 which are inserted in recesses in the slide l8, and fast on the shaft is a bevel-gear'iii! engaged by another bevel-gear 64 provided with a cylindrical stud 66 mounted in a bearing in one side of the slide 18 It will thus be seen that by turning the gear 6'4 the interiorly threadedblock 50 may be moved in one direction or the other lengthwise of the shoe, carrying with it the member 3?: upon which the rack teeth 38 are formed, and that through the connections between these rack teeth and the slides 22 the wipers are adjusted about the axis of their swinging movements. Forturning the gear 64 there is mounted in the head of the ma chine a shaft 68 having on its inner end a tongue arranged to enter ,a recess 72 formed in the stud 66 when the shaft 68 is moved inwardly from the position illustrated'in Fig. l. The shaft 68 may" thus be moved inwardly against the resistance of a spring 14 which acts normally to hold it disconnected from the stud 66 and thus to avoid interference with the operative movement of the slide l8. When the parts of. the machine are in starting positions, as illustrated in Fig. 1, the

shaft 68 is in alinement with the stud 66 and the tongue 10 may be connected to the stud by push ing the shaftinwardly. Thus by the use of a hand wheel 16 on the shaft the required adjustment of the wipers laterally of the shoe may be made.

Inthe-illustrated machine the margin of the upperis secured in lasted position on the heel seat by upper-fastening tacks whichare driven through openings in the wipers in locations near their wiping edges by means carried by the wipers. This means may be and preferably is the same as the means fully shown and described in the above-mentioned Letters Patent No. 1,852,015 and accordingly need not be describedin detail.

In the machine herein shown there is further provided for purposes of this invention means for varying the amount of closing movement imparted to each of the wipers I4 and I 6 without substantially altering the adjusted positions of the wipers relatively to each other laterally of the shoe when the machine is initially at rest. It will 1 be understood that as the wipers are advanced by the forward movement of the slide l8 closing movements of predetermined extent are imparted to'the wipers by the inward movements of the slides 22 and that the wipers are guided in their movements lengthwise of the shoe by the rolls 39 andthe slots 28 formedin the plates 26 on the slides 22. In the illustrated construction the plates 26 are mounted on the slides 22 for movements about axes which are so located as to permit the plates to be adjusted relatively to the slides without imparting to the wipers any swinging movements toward or from each other widthwise ofthe shoe when the wipers are in their open positions. As shown, particularly in Figs. 1 and 4,

each plate 26 hasformed on its upper face a curved tongue 18 lying in a curved slot 80 in the slide 22, and on its inner side face each plate is provided with a curved rack 82 which is engaged by a pinion 84 carried by the slide 22. Engaging the teeth of each pinion 84 is a rack member 86 which is slidingly mounted in a recess in the slide 22 and to which movements in directions lengthwise of the slide may be imparted by an adjusti'ngscrew 88 threaded in the slide and provided with spaced shoulders engaging the opposite side faces of a projection 90 on the rack member, the construction being such that by movement of the screws 88 the plates 26 may be adjusted relatively to the slides 22 without varying [the relative positions of the wipers and the slides.

The slots 28 are so formed that when the plates 26 are in the adjusted positions shown in Fig. 1 substantially no additional closing movements are imparted to the wipers in the forward movement of the slide 18 by reason ofthe movement of the I rolls 30 along the slots 28. Outward movements of the rack members 86 along the slides 22, however,

will impart to the plates .26 swinging movements in; directions to carry theforward ends of the 1 slots 28 toward-each other and thus to cause addi- .member.

tional closing movements to be imparted to the wipers in response to the movement of the wipers lengthwise-of. the shoe by reason of the angular relation of the slots 28 to the direction of such movement. Eachrack member 86 may be adjusted relatively 'to its slide 22 within limits determined by a pin 92 which is carried by the slide 22 and is arranged to engage the rack member at the opposite ends of a slot 94 formed in the rack Each slide 22 has formed therein. an arcuate slot 96 concentric with the curved tongue 18 on the plate 26 and through which extends the reduced shank portion 98 of the screw. 24. As shown particularly in Fig. 4, the screw 24 is threaded in the plate 26 and has a shoulder 99 which bears on the upper surface of the slide'22.

moreover; may be adjusted, differently to cause a.

greaterclosing movement to be imparted to one of the wipers than that imparted to the other wiper when operating on shoes the opposite sides of the heel-end and shank portions of which differ considerably in curvature. These adjustments, as hereinbefore described, are made without varying substantially the relation of. the wipers to each otherwhen they are in their open positions. It willthus be seen that the wipers may be so. operated under varying conditions that notonly will. the margin of the upper be wipedinwardly over the sole for substantially its entire width around the end and along the opposite sides of the heel end of the shoe, but by reason of the locations of the wipers at the end of their closing move-,

ments the upper-fastening tacks will be inserted at substantially uniform distances from'the edge of the shoe bottom around the entire heel seat. It will be understood that in addition to adjusting the plates 26 in the manner described when required by the character of the work, the operator also will adjust the wipers preliminarily toward or from each other as heretofore for shoes of different sizes by use of the hand wheel 16.

In order to produce the best results at and near the junction of the heel-end and shank portions of shoes it is desirable, particularly on welt work, to subject the upper to an inward wipe in locations forwardly of the heel seat. For this purpose, as herein shown, the wipers l4 and I6 are each provided with forwardly extending offset portions 99 arranged to wipe the portions of the margin of the upper just forwardly of the heel breast line inwardly over the feather and against the rib of the insole.

, The means for supporting the last and shoe for the operations hereinbefore described comprises a jack mounted for swinging movements in directions lengthwise of the shoe to carry the shoe into and out of lasting position in the same general manner as illustrated in Letters Patent No. l,558,-

the jack andprior to the starting of the machine the operator, as in the use of prior machines, swings the jack rearwardly to carry the shoe into the heel band iii. In the power operation of the machine the upper is clamped around the heel end of the last by the heel band before the margin of the upper is wiped inwardly over the sole by the wipers. To permit each shoe to be positioned with the'heel seat substantially parallel to the plane of the wipers notwithstanding such variations as there may be in the angular relation of the spindle holes to the. bottom faces of the different lasts, the illustrated machine is provided with means which is substantially the same'as that disclosed in Letters Patent No. 1,896,121, granted February 7, 1933, upon an application of mine; As more fully shown and describedin said Letters Patent, there is mounted at the upper end of the post Hi2 .in a laterally extending slot 6% a block 188 which carries the spindle I84. For engaging the top face of the cone of the last there is mounted on the block I08 a plate I89 provided at its opposite edges with downturned flanges I H having arcuate lower edges supported on similarly curved shoulders of the block, the plate being provided with an opening H3 considerably larger than the spindle m4 and through which the spindle extends. The slot IDS is formed to provide a guideway for the block curved about an axis which extends lengthwise of the shoe and is located as indicated at 2 (Fig. 3) substantially at the heel seat face of the shoe. By movement of the block Hit in the slot a tipping movement may be imparted to the shoe to position the opposite sides of the heel seat in the same relation to the wipers without substantial bodily lateral displacement of the shoe relatively to the post 12. It will be understood that the block I08 and the spindle Hi l are normally centralized by spring means (not shown) and that the block and spindle may be'moved against the resistance of said spring means in one direction or the other to impart tothe shoe its tipping movement. It will be understood also that such movement may be effected by the operator as he presents the shoe to the machine or the movement may result from excess of pressure of the wipers on one side or the other of the heel seat, the arrangement being such that'if the shoe is not presented initiallyin position to receive substantially the same wiper pressures at the opposite sides of the heel seat, the pressures will be equalized automatically in the operation of the machine.

For best results in the heel'seat lasting operation it is desirable that the shoe be so supported as to permit its heel end to be centralized relatively to the wipers by the heel band while the band applies substantially equal pressures to the upper at the opposite sides of the shoe. Because of variations in the shapes and lateral locations of the cones of diiferent lasts the spindle holes, which are usually bored each in the center of the cone of the last, are frequently not located at uniform distances from the opposite side faces of the heel-end portions of the lasts. The machine herein shown is accordingly further provided with shoe-supporting means constructed to permit bodily movement of the shoe laterally so that the heel-end portion of the shoe may be centralized by the heel band, the construction shown being such that the position of the heel seat relatively to the plane of the wipers is substantially unaffected by the bodily movement. For the purpose in view, there is pivotally connected to the casing Hill for swinging movements about an axis extending lengthwise of the shoe a member H8 in which the post I02 is slidingly mounted for movements in directions heightwise of the shoe. As shown, particularly in Fig. 2, the casing lilil is provided with trunnions H2 and lid arranged to extend loosely into alined bores formed in the lower portion of the member lid in locations comparatively remote from. the shoe, the construction being such that the member HI] and the post I02 may swing about the axis of the trunnions in either direction to permit bodily movement of the shoe laterally to position its heel-end portion laterally in proper relation to the wipers. If the heelend portion of the last is non-symmetrical, the spindle hole in the last will be located nearer one side of the shoe than the other side, as illustrated in Fig. 3, so that swinging movements of the member H9 in opposite directions are required to centralize right and left shoes respectively in relation to the wipers. Since the axis of the trunnions H2, lid is so far below the shoe, such bodily lateral movement of each shoe as is required for the purpose in view is without any substantial effect on the relation of the heel seat to the plane of the wipers determined by the position of the block 588 in its guideway 96. The member H and post I92 are normally held centralized by a spring l l6 which is mounted in a recess in a block l 18 secured to the member lit. The spring is held under compression between disks i253 which are slidingly movable in the recess in which the spring is mounted and are arranged to engage the inner side faces of a pair of spaced projections I22 on the casing 595. It will be evident that, while the member i it and post an are normally centralized by the spring H6, they may be swung in either direction by the operator about the axis of the trunnions i it, I as against the resistance of the spring to position the heel-end portion of the shoe properly within the heel band as the shoe is presented to the machine or such movement may be effected by the heel band as it is closed about the heel end of the shoe in the power operation of the machine. I

In right or left lasts of the same style the spindle holes are usually located in substantially the same positions relativelyto the opposite side faces of the heel-end portions of the lasts and accordingly, in order to assist the operator in presenting the shoes to the machine, it is desirable that means be provided for limiting the swinging movement of the member I!!! and the post Hi2 laterally of the machine. For this purpose there is slidingly mounted in a guideway on the casing Hi6 for movements in directions heightwise of the shoe a plate I26 which is provided with a central slot E28 (Fig. 3); At its upper end the plate i2 1 has a pair of inclined surfaces l28 which extend upwardly and outwardly from the opposite side faces of the slot H26, and projecting from the member H0, substantially midway between the axis of the trunnions HZ, HQ and the upper end of the member, is a pin iiiii which is arranged to engage one or the other of the inclined surfaces I28 to limitswinging movement of the member H0 and the post H32 in either direction. The plate ltd is movable along its guideway by means of a stud L32 which is threaded into the plate and extends outwardly into a convenient position to be grasped by the hand of the operator. It will be evident that the limits of swinging movement of the member H and'the post I 02 may be varied and determined by movement of the plate I24 to adjust the positions of the inclined surfaces I28 relatively to the pin l3ll. For holding the plate 124 in adjusted position there is provided a spring-pressed detent I34 carried by the casing I00, and arranged to engage any one of aseries of teeth I36 formed upon the right-hand edge face of the, plate (Fig. 3). It will be understood thatthe angle formed by each inclined surface l28,and;the side face of the slot I26,is the same so-that the operatorin presenting, to the machine shoes of "the same style may swing the jack in" either direction to locate the heel ends of right or left shoes in'the proper relation to the heel band-and to the wipers. To look the heel post 102 and the member I I0 against swinging movement laterally of the shoe, which sometimesmay be desirable, particularly when operating on shoes mounted on lasts the heel-end portions of which are symmetrical, the plate I24 maybe moved upwardly until the pin l3!) enters theslot I26.
