  • This invention relates to lasting machines and has more particularly in view' the provision of certain improvementsin a machine shown and described in an earlier application of mine, Serial No. 189,407, filed on October 10, 1950.
  • the invention is accordingly herein disclosed as applied to an organization .of that character, but it is to be ,understoodthat in various, novel aspects it is not limited to this illustrative embodiment.
  • I 1 The machine shown in the above-mentioned application is a machineior lasting the ODDOSi-te sides of the ball portions of shoes extending from the toe portions to the shank portions.
  • the wipin means includes at each side of the shoe a pairoi wipers arranged to extend continuously, each beyond the other, along the side or the shoe and relatively movable in directions lengthwise of the shoe while maintaining such continuity, the machine having means positioned as determined by engagement with the toe-end face of each shoe when the shoe is.
  • the present invention provides improved means for controlling the wipers in such manner as to accomplish the aboveresult.
  • showriffthe wipers which extend nearest to the toe end ofthe shoe are moved more or less in directions lengthwise of the shoe relatively to the other wipers at the time ,when'the shoe is. presented to the machine by a member connected to them 'an'dengaged and moved by the toe-endface of the shoe. They are, moreover, thus moved rectilinearly instead 2 of being swung about.
  • the invention furtherprovides wiping means having especially in view an improvement/in the results obtained in wiping the upper inwardly over the insole in locations where the bottom of the shoe curves heightwise of the shoe toward the shank portion beyond the ball line.
  • the wipers above referred to as extendingnearest to thetoe end of the shoe are arranged to overlap portions of other com-v paratively thin wipers made of resiliently flexible metal and having portions arranged to extend beyond the first-mentioned wipers toward the" heel end of the shoe for engaging-the upper in the above-mentioned locations beyond the ball line.
  • These portions of the flexible wipers have normally a curvature approximating that of the corresponding portions of theshoe bottom, but such as to insure that in moving inwardly from positions outwardly retracted beyond the edge of the insole they will not displace the marginot the insole.
  • the machine is provided with means for automatically bending them heightwise of the shoetoward the shoe bottom in predetermined time relation. to theirin- Ward movements and for thus conforming them to the contour of the bottom of the shoe.
  • the bending'thereof is timed to take place only after. their wiping edges have passed the extreme edge of the insole in their inward movements, but prior to the completion of their inward movements, so
  • the bending means comprises fluid-operated devices which arefmoved inwardly with the wipers and, though subjected tofiuid pressure, are prevented by latches from operating until the proper time, the latches being then re- 3 tracted in response to the inward movements of the wipers to cause the bending thereof as above described.
  • the shoe is positioned bottom upward by means engaging the bottom of its fore part, and it is clamped against this positioning means by an upwardly movable toe rest.
  • a member which adjusts itself to the back cone (or heel end) and the front cone of the inverted last underneath and is thereafter securely held against downward movement in supfiorting relation to the last.
  • memb r comprises a plate mounted to tip: yieldingly about an axis extending widthwise or the last and further so supported yieldingly as to permit it to be depressed bodily more or less byengagement of the last therewith when the slroefis presented to the machine.
  • the toe rest includes a shoe-engaging member mounted for tipping move"ent about an axis extending lengthwise of each shoe in response to engagement of the shoe" therewithto conformto the lateralsl'ope ofthe top of the forep art' of thes hoe, and this member will more readily tip to conform to right am left shoes if it is thus shifted to different pd tions for the different shoes prior to engage: merit therewith.
  • the "machine hereiii hown s provided for aiitomatically shifting the opposite side grippers to different positions for operating alternately on right andleft shoes in successive cycles of oper ations of the machine; and for shifting the toe rest as above describedthe construction herein shown includes connections between it are the means for thus shifting the grip ers to cause it to be shifted as desired simultaneously with the grip'pers.

  • a shoe rest member 2 (Figs. 1 and 1) having on its lower end two presser feet 4 (Fig. 8) spaced apart widthwisjeof the shoe and provided with teethfor engaging the insole at the ball portion of the shoe, this member corresponding to the member l0s'hown in theabove-mentioned application and being supporte'd and controlled in the same manner as that member. Accordingly, the member 2 is held stationary when the shoe is first engaged there with and during thegreater portion of the opera;- tion of the -machine.
  • FIG. 6 tioning the hoe there is provided another shoe rest member 6 on which are two downwardly eliten ding bosses 8 spaced apart widthwis of the shoe; and arranged to engage the toe-end portion of the insole' these bosses in the construction herein, shown also having insole-engaging teeth thereon.

  • the lower face of theholderi is convexly curved about that axis and rests on rolls 54 supported by the block, only one of these rolls being visible in the drawings.
  • Flanges 56 on the holder are-engaged by flanges 58 on the block to retain the holder in position on the block, and the tipping movement of the holder is limited by engagement of the head of a screw 60 thereon with shoulders 62 on the block.
  • the block 52 is mounted on a T-shapedguide 64 for rectilinear movements in directions widthwise of the shoe, this guide having a depending portion 66 mounted in an upward extension 68 of a piston Ill-for rectilinear movements in directions lengthwise of the shoe.

  • the piston This movable upwardly in a forwardlyinclined direction in a cylinder I! by operating fluid admitted to the lower end of the cylinder substantially at the beginning of a cycle of operations of the machine, as in the machine described in the earlier application, such upward movement of the piston being effected against the resistance of a pair of return springs 18 only one of which is shown.
  • the toe rest is moved into engagement with the shoe on the top of the forepart and clamps the shoe against the shoe rest members 2 and 6, the member 6 being swung slightly upward by the pressure thus applied to the shoe to cause the teeth thereon to engage the teeth on the block.
  • Each of the grippers 28 (Fig. 8) comprises a pair of-upper-gripping jaws and 82 associated with a holddown 84 which is arranged to engage the margin of the insole in the upper-pulling operation to provide a purchase on the bottom of the shoe for a fluid-operated lever by which the gripper is moved upwardly to pull the upper, as disclosed in detail in the previouslymentioned application.
  • the two grippers are thus parts of gripper and holddown units 86 (Fig. 6) mounted to swing about pins 86 extending heightwise of the shoe for differently positioning the grippers and holddowns in operating on right and left shoes respectively.
  • thegripper which is to grip and pull the upper at the inner side of either shoe is positioned nearer the toe end nected atits opposite endsrespectively to the different units through rods 94. It will 'thusbe seen that by the swinging of the-lever 98 in on direction or the other the two units are swung simultaneously about the pins 88 in opposite directions respectively lengthwise of the shoe. The lever an is thus swung automatically near the end of each cycle of operations of the machine to shift the grippers and holddowns to positions for operating on a right shoe in one cycle and to positions for'operating on a left shoe in the next cycle.
  • lever 90 there is pivotally connected at one end to the lever 90 another lever 96 having therein a slot 98 through which extends a pin I66 providing an adjustable fulcrum for the lever 96 for varying the amount of movement imparted to the units 86.

  • the links I14 diverge from each other in directions toward the heel end of the shoe, and accordingly they approach a parallel relation as the wipers are swung inwardly.
  • the effect of the inward swinging movements of the links therefore, is to impart to the wipers I62 and the plates I68 thereon movements of some extent lengthwise of the shoe toward its heel end as they wipe the upper inwardly over the insole.
  • the machine is further provided with additional wipers I18.

Bernhardt Jorgcnsen,
signor to United Shoe Machinery Corporation,
Flemington, N. J., a corporation of NewJersey Application October 4, 1951, Serial No. 249,7 02
1 h This invention relates to lasting machines and has more particularly in view' the provision of certain improvementsin a machine shown and described in an earlier application of mine, Serial No. 189,407, filed on October 10, 1950. The invention is accordingly herein disclosed as applied to an organization .of that character, but it is to be ,understoodthat in various, novel aspects it is not limited to this illustrative embodiment. I 1 The machine shown in the above-mentioned application is a machineior lasting the ODDOSi-te sides of the ball portions of shoes extending from the toe portions to the shank portions. It includesapair of grippers for gripping and pulling the upper at .the opposite sides ofthe ball portion ofoeach shoe respectively, and means for thereafter wiping the marginal portion of the upper inwardly over an insole on the last into position to adhere to the insole through the/ac.- tion of cement. The wipin means includes at each side of the shoe a pairoi wipers arranged to extend continuously, each beyond the other, along the side or the shoe and relatively movable in directions lengthwise of the shoe while maintaining such continuity, the machine having means positioned as determined by engagement with the toe-end face of each shoe when the shoe is. presented to the machine forcausingsuch relative movement of the wipers thereafter to take place in the course of their operative'move ments before they arrive in' positions to act on the upper and for thereby determining t e CE tance lengthwise of the shoe of the engagement ofthe pairs of wiperswith the uppe'r in accordancewith the position of the toe-end face of the shoe. Since the operator, in presenting each shoefto the machine, positions ithlength'wi'se by sight with reference to the side grippers, the toe-- end faces of shoes of different sizes are different- 1y positioned, and accordingly the wipers are so controlled as to vary the distance lengthwise of the shoe of their engagement with the upper'in accordance with the size of the shoe.
The present invention, in one aspect, provides improved means for controlling the wipers in such manner as to accomplish the aboveresult. In the construction herein showriffthe wipers which extend nearest to the toe end ofthe shoe are moved more or less in directions lengthwise of the shoe relatively to the other wipers at the time ,when'the shoe is. presented to the machine by a member connected to them 'an'dengaged and moved by the toe-endface of the shoe. They are, moreover, thus moved rectilinearly instead 2 of being swung about. axes extending heightwis'e of the shoe as are the corresponding wipers in the earlier construction- The connections beward parallel relation and thereby move those wipers to some extent reversely lengthwise .of-the shoe relatively 'to the other wipers, thereby coun I teracting suchtendency as they may'have, bee
cause of the directions in which they are'moved inwardly over the shoe bottom, to deflect the margin of the upper unduly toward the toe end of the shoe. p l L The invention furtherprovides wiping means having especially in view an improvement/in the results obtained in wiping the upper inwardly over the insole in locations where the bottom of the shoe curves heightwise of the shoe toward the shank portion beyond the ball line. In the construction shown the wipers above referred to as extendingnearest to thetoe end of the shoe are arranged to overlap portions of other com-v paratively thin wipers made of resiliently flexible metal and having portions arranged to extend beyond the first-mentioned wipers toward the" heel end of the shoe for engaging-the upper in the above-mentioned locations beyond the ball line. These portions of the flexible wipers have normally a curvature approximating that of the corresponding portions of theshoe bottom, but such as to insure that in moving inwardly from positions outwardly retracted beyond the edge of the insole they will not displace the marginot the insole. To render those portions of the wipers properly effective in wiping the upper inwardly and in pressing it on the insole, the machineis provided with means for automatically bending them heightwise of the shoetoward the shoe bottom in predetermined time relation. to theirin- Ward movements and for thus conforming them to the contour of the bottom of the shoe. The bending'thereof is timed to take place only after. their wiping edges have passed the extreme edge of the insole in their inward movements, but prior to the completion of their inward movements, so
that they will have an inward wiping action on the upper after being fully conformed to the contour of the shoe bottom. .Inthe construction shown the bending means comprises fluid-operated devices which arefmoved inwardly with the wipers and, though subjected tofiuid pressure, are prevented by latches from operating until the proper time, the latches being then re- 3 tracted in response to the inward movements of the wipers to cause the bending thereof as above described.
To render the above-mentioned heelwardly extending portions of the flexible wipers properly effective it is important that the portions of the shoe on which they act shall be firmly supported against the pressure applied to the wipers by the bending means. In the machine herein shown the shoe is positioned bottom upward by means engaging the bottom of its fore part, and it is clamped against this positioning means by an upwardly movable toe rest To insure further against any tipping of the s oe such as might affect unfavorably thje'a'ction of the above-mentioned flexible w'pers' thereon, there is provided a member which adjusts itself to the back cone (or heel end) and the front cone of the inverted last underneath and is thereafter securely held against downward movement in supfiorting relation to the last. As herein shown; in memb r comprises a plate mounted to tip: yieldingly about an axis extending widthwise or the last and further so supported yieldingly as to permit it to be depressed bodily more or less byengagement of the last therewith when the slroefis presented to the machine. I At a prede- I tar-mined time in theoperation of the machine a age. qn iuw r y s em into supp ing relation to the plate and is positi"'ely loclzed against' rev erse downward movene rby means wh'ich is rendered effective by the fist id rm et' i we i es It has been found that right and left shoes are better supported by the toe rest against the pressure applied a thereto the wipers at the oppos te sides ofthe forepart or the shoe bottomfi'f the toe rest is" shifted to some extent in. directions withwise of the shoe to different peep tie for rightand left shoes respectively. This erisesnon the fact that the toe rest includes a shoe-engaging member mounted for tipping move"ent about an axis extending lengthwise of each shoe in response to engagement of the shoe" therewithto conformto the lateralsl'ope ofthe top of the forep art' of thes hoe, and this member will more readily tip to conform to right am left shoes if it is thus shifted to different pd tions for the different shoes prior to engage: merit therewith.- In accdrdano'e with the dis ensur the earlier application the "machine hereiii hown s provided for aiitomatically shifting the opposite side grippers to different positions for operating alternately on right andleft shoes in successive cycles of oper ations of the machine; and for shifting the toe rest as above describedthe construction herein shown includes connections between it are the means for thus shifting the grip ers to cause it to be shifted as desired simultaneously with the grip'pers. v I v V "The above and other features of the invent-ion, including various noveldetails of construc ti and combinations of parts. will now be more particularly described with reference to the ac edmasfi mg drawings and thereafter pointed out iii the claims;

In view of the disclosure I in the above-men: tionedapplication, the present description will be confined to such portions of the machine as it is necessary to refer to for an understanding of the invention.
For positioning the shoe heightwise in the machine there is provided a shoe rest member 2 (Figs. 1 and 1) having on its lower end two presser feet 4 (Fig. 8) spaced apart widthwisjeof the shoe and provided with teethfor engaging the insole at the ball portion of the shoe, this member corresponding to the member l0s'hown in theabove-mentioned application and being supporte'd and controlled in the same manner as that member. Accordingly, the member 2 is held stationary when the shoe is first engaged there with and during thegreater portion of the opera;- tion of the -machine. Furtherto assist in son: tioning the hoe there is provided another shoe rest member 6 on which are two downwardly eliten ding bosses 8 spaced apart widthwis of the shoe; and arranged to engage the toe-end portion of the insole' these bosses in the construction herein, shown also having insole-engaging teeth thereon. The member 6 corresponds generally to the member 54 shown in the above-mentioned application, and it ispivo'tally mounted at its rear end on a pin 1 ll supported in upstanding lugs on a slide 14 which is guided for'forward and rearward, movements a holder 16 secured to a ill on the frame. Spring means hereincasting after described tends to move the slide l4 in a forward direction, its forward movement being limited by its engagement with a stop pin 22ml the holder [6. Adjustab1y secured to the member 6 by a screw 21 is a member 26 arranged to be engaged by the toe-end face of the shoe when the two spring-pressed pins 32 (Fig. :1) which are mounted in a block 34, this block'being pivotally mounted on a 'pin 36 supported on the lower ends of two links 38, only one of which is herein shown; These links correspond to the links 84 shown-in the previously mentioned application: and are controlled generally in the same manner as those links. Initially, therefore, and during the greater portion of the operation of the machine, the
links 38,- and accordingly the'block 34, are'held against upward movement. In the construction herein shown the upper face of the member 6 has two rows of teeth thereon, between which rows the pins 32 engage th membenandthe lower face of the block 34 also hasteeth thereon which are initially out of engagement-with the teeth on the member 6 by reason of the action of the spring-pressed pins 32 onthi member, thus permitting the rearward movement ofthe-member 6 by the shoe whenthe shoe is presented to .themachine. When the shoe is pressed upwardly against the shoe rest members 2 and 6, as hereinafter described, the member 6 is swung upwardly against the resistance of the pins 32 by thepressure of the shoe thereon, thus causing the teeth on this member to engage the teeth on the block .34. In this manner the member 6 I is locked against further rearward movement for .apurpose hereinafter explained.
While the shoe is still held in. the operators hands after he has presented it to the machine it is automatically positioned widthwise in proper relation to the lasting instrumentalities by side clamps 40 (Figs. 1 and 8) whichengage it at the .oppositesides of the forepart. These side clamps differ only in details which need notbe described from; clamps provided for .the same purpose in the machine shown in the earlier application.
They; are supported on levers 42 which are mounted to swing widthwise of the shoe an are operated by fluid-pressure means in the same manner as corresponding levers I 04 shown in the earlier application. s
After the shoe has been positioned laterallyzby the clamps 40 it is pressed upwardly against the shoe rest members 2 and 6 by a toe rest 46 (Figs. 1, 4 and 7). This toe rest comprises a rubber pad ;.48 having a shoe-engaging face which i convexly curved lengthwise. of the shoe and is slightly concave widthwise of the shoe, the pad being secured toa holder 56 which is guided on a block 52 for .tipping I movements about an axis extending lengthwise of the shoe to'permit the pad 48 to adjust itself in this manner to the shoe. For this purpose the lower face of theholderiis convexly curved about that axis and rests on rolls 54 supported by the block, only one of these rolls being visible in the drawings. Flanges 56 on the holder are-engaged by flanges 58 on the block to retain the holder in position on the block, and the tipping movement of the holder is limited by engagement of the head of a screw 60 thereon with shoulders 62 on the block. The block 52 is mounted on a T-shapedguide 64 for rectilinear movements in directions widthwise of the shoe, this guide having a depending portion 66 mounted in an upward extension 68 of a piston Ill-for rectilinear movements in directions lengthwise of the shoe. A screw 12 threaded in the extension 68 has a conical end extending into a V-shaped groove I4 in one side of the depending portion of the guide 64 o secure the toerestin 6. any position ofadjustment lengthwise of the shoe- Means provided for adjusting the block 52 widthwise of the shoe along the guide 64 will be hereinafter described, such movements of the block being limited by a screw I5 which is threaded therein and extends into a slot I6 in the guide 64.
The piston This movable upwardly in a forwardlyinclined direction in a cylinder I! by operating fluid admitted to the lower end of the cylinder substantially at the beginning of a cycle of operations of the machine, as in the machine described in the earlier application, such upward movement of the piston being effected against the resistance of a pair of return springs 18 only one of which is shown. In this manner the toe rest is moved into engagement with the shoe on the top of the forepart and clamps the shoe against the shoe rest members 2 and 6, the member 6 being swung slightly upward by the pressure thus applied to the shoe to cause the teeth thereon to engage the teeth on the block.
Each of the grippers 28 (Fig. 8) comprises a pair of-upper-gripping jaws and 82 associated with a holddown 84 which is arranged to engage the margin of the insole in the upper-pulling operation to provide a purchase on the bottom of the shoe for a fluid-operated lever by which the gripper is moved upwardly to pull the upper, as disclosed in detail in the previouslymentioned application. The two grippers are thus parts of gripper and holddown units 86 (Fig. 6) mounted to swing about pins 86 extending heightwise of the shoe for differently positioning the grippers and holddowns in operating on right and left shoes respectively. That is, thegripper which is to grip and pull the upper at the inner side of either shoe is positioned nearer the toe end nected atits opposite endsrespectively to the different units through rods 94. It will 'thusbe seen that by the swinging of the-lever 98 in on direction or the other the two units are swung simultaneously about the pins 88 in opposite directions respectively lengthwise of the shoe. The lever an is thus swung automatically near the end of each cycle of operations of the machine to shift the grippers and holddowns to positions for operating on a right shoe in one cycle and to positions for'operating on a left shoe in the next cycle. For this purpose there is pivotally connected at one end to the lever 90 another lever 96 having therein a slot 98 through which extends a pin I66 providing an adjustable fulcrum for the lever 96 for varying the amount of movement imparted to the units 86. At its other end the lever 96 is connected by a link I02 to a crank pin I04 on a gear wheel I06 in'mesh with a larger gear wheel I08. Mounted to turn with the gear wheel I08 is a' disk IIIl having thereon four pins II 2 spaced equal distances apart succession and thereby to turn the disk M each timeniiistance such as to impart tothe crank pin .1104 a movement of 180. Aspiring-pressed pin I24 in the piston "I 16 engages a fiat .iaceon the latch [22 and holds the datch normally upraised in the .position shown in :Fig. 1., Upon forward movement of the piston by theoperating fluid the latch is deflected downwardly by the next pin H2 until it snaps upwardly .into position to connect with :this pin, after which it :acts to turn the disk I it as above described in response to rearward movement of the piston effected by springs 128 connected to :the pin l l8. .The movements of the piston in opposite directions are limited by engagement of the pin :8 with the cylinder Id at the opposite ends of the slots J10. To hold the disk H0 againstdisplacement when the latch is moved forwardly into posi-v tion to connect with the next pin H2, there is provided a spring-pressed detent I28 :having a V-shaped end arranged to enter one or another of four V--shapedrecesses I30 in the periphery of thedisk.
- There is tfurther provided means whereby the operator may at=any time prior to the operation of .themachine on a shoe-shift thegripper and holddown units 86 manually into positions for operating on a right shoe or a left shoe selectively. .Fo'r thisipurpose a forwardly and rearwardly extendingrod 132 guided in the frame and in abracket 434 has a flattened rear portion formed .to' ser-ve as a latch [36for engaging one or :anotheaof the pins 1 I 2 and for thereby turningithe dish 1.16 .in the :same direction in which it is turned by the latch I22. The disk. is thus-turned a quarter revolution by forward movement of the rod 432 against the resistance of a return spring .(not-shown). When the latch isreturned by this spring it is deflected upwardly by engagement with "the next pin H2 until it arrives in position to connect with that pin. To-permit suchupward deflection-of the latch the flattened portion of the rod 4.3-2 extends through a ver- .tical slot in the bracket 134. It will be understood that when the disk It!) is thus turned manually the pins H2 pass idly over the latch LZZ-and that when-the disk is turned bythis. latch the pinspass idly under the latch I36.
.Asis well known, the top of the forepartof ;a last is-usually somewhat higher near the inner side .of the last thannear the outer side, especially in .a-location comparatively remote from the end of the .toe. To aiiord better insurance 'that the .toe rest 4.6 will support the shoe 'aswwell against pressure applied .theretoby the wiping means at the .outer side of the shoe bottom as against that applied at the inner sideof theshoe bottom, mechanism is provided for shifting the toe rest laterally to difierent positions for rightandleft shoes, so that the toe rest pad will more readily .tip .into a position conformable to the lateral slope-of the top of the forepartcf the shoe upon contact with the shoe. .This requires that foresupporting aright shoe positioned in the machine the toe-rest be shifted toward the. left (Fig. .8') and that for supporting .a leftshoe it beishifted toward theright. For thus shifting the toe-rest there is provided a flexible wirecable 138 secured at one end toastud M0 mounted on :the block 52 which is movable as hereinbefore described in directions widthwise of the shoe along the guide .64. The cable l.3-8-extends through a flexible guide I42 one end of which isfast in a clamp M4 ;secured tothe upward extension 68 .of the'jpiston 10. The other end'of the cable-isslidingly mounted in'the lower end of a pin I46 (Fig. '1) extending downwardly from the left-hand end of the gripper-shifting lever 98. Secured by setscrews to the cable at the front and rearof the pin .146, respectively, are collars I48. When the-lever-Qfi, therefore-is swung to shift the gripper land-holddown units '86 to positions for operating .on a rightsshoe, the pin 146 acts-on the rear collar 21.48, as shown, to move the .cable .138 in the direction to-shift the toe'rest '46 to the position appropriate for that .shoe. Similarly the movement of the lever to shift the units :86 into positions .for a'leftzshoelcauses the pm 146 to act on the other collar 8 and thus to shift the toe rest to the position :for that shoe. .As shown in Fig. 1, "the collars 148 are so positioned on the cable ,as {to provide" for some lost motion before the pin H6 becomes :effiective to shift the toe rest, the movement of the-toe rest in each direction being lim ited by the screw 15 and the slot '16 For-wiping the'margina-l'portion of the upper inwardly over the "insole .into position to adhere to the 1113016310113thG' OPDOSltBSideSiCfth ball portion of 'each shoe after the upper has been pulled :by upward movements :of the grippers :18 the machine is provided :with wipers carried 'by levers [50 (Fig. 2) which are mounted to swing widthwise of the shoe about studs i152 and are connected together -by teeth J 54 to equalize their movements, these levers corresponding to the levers 542 shown in the previously mentioned application and being operated similarly to those levers by fluid-pressure means 'at the required time in the operation of the machine. In the construction herein shown there is secured'to each lever 1'50 underneath, in a location sspaced'f-rom the lever, a-plate' il:-56 (Figs. f3 :and '9) and guided on'the top ofzthis'plate for rectilinear movements in directions lengthwise of the shoe is a wipercarrying plate I58. 1Secured bytwo screws 1:60 to an outer downwardly extending portion of *the plate |-58.is a wiperp ate or wiper cs2 arranged to extend :inwardly toward the shoe :under the plate [56in contact therewith,-the wiper f62having .a wiping edge extending straight lengthwise of the shoe for engagement with the upper. The inner portion'of'the wiper 1'62,- i. e., the'portion'losated nearest the shoe, is siightlycfisetzupwardly from otherportions thereof, the plate l56 havin'g therein ia'recess l6i4 (Fig '9) to receive this offset portion 'Of. the wiper. This construction provides in thewiper 162 a recess (66 (Fig. 3) and-bridging this :recess is another thinner wiper plate 168 which :is resiliently flexible. As shown in :9, the inner edge oftheplate lBS-is slightly spaced in an outward direction from the inner edge of the Wiperrltlandas more clearly shown ini'ig. 3 the inner edge portion of :the plate 188 isrin engagement .withthe lower face of thewiper 1B2. The plate I 68 :is secured to the wiper 152 intlocations comparatively remote from the shoe byatwo studs lflflgtheportion of'theplate'in which these studsrareilooated being spaced somew'hatbelow thewwiper 1.62. It will thus be seen that in .the'vliping operation the upper is engaged by the edgezofithe'wiper l 62 slightlybe'fore it is engag'ed bythezplate Hi8, portions of thisplate being yieldable aheig'htwiseoi the shoe-relatively to-the'wiper 1.62 to :conform better to the-contour of the shoe bottom.

Forlpositioning the-wipersfitzlengthwiseofthe slice the. slidable plates i5 8 to which theyare-secured are connectedibylinks 1H (Fig-*2) to the 9 upstanding lugs I 2 on the slide I4 which is guided as hereinbefore described for movements lengthwise of the shoe in the holder I6. The plates I58 are controlled by springs I16 connected to them and to the corresponding levers I50, these springs tending to move the plates and the wipers I62 thereon, together with the slide I4, forwardly toward the front of the machine. Such movements of the plates are limited when there is no shoe in the machine by contact of the slide I4 with the previously mentioned stop pin 22. When the operator moves the slide I4 in a rearward direction, as hereinbefore described, by engagement of the toe-end face of the shoe with the member 26, until the sides of the ball portion of the shoe are in proper relation to the grippers 28, rearward movements also are imparted through the links I14 to the plates I58 and the wipers I62 to position these wipers lengthwise of the shoe. This determines the distance of the wipers I62 from the end of the toe, and it will be evident that this distance will be the same for different shoes regardless of such variations as there may be in the positions of the shoes lengthwise as they are presented to the machine by the operator. It will be further evident, however, that the distance of the wipers I62 from the end of the toe may be varied by adjusting the toeengaging member 26 relatively to the shoe-rest member 6 on which it is mounted.
The studs I52 about which the levers I50 are swung are so located that in wiping the upper inwardly over the insole the wipers I62 have components of swinging movement lengthwise of the shoe toward its toe end. As illustrated in Fig. 2, however, the links I14 diverge from each other in directions toward the heel end of the shoe, and accordingly they approach a parallel relation as the wipers are swung inwardly. The effect of the inward swinging movements of the links, therefore, is to impart to the wipers I62 and the plates I68 thereon movements of some extent lengthwise of the shoe toward its heel end as they wipe the upper inwardly over the insole. This serves to counteract any tendency for the wipers to deflect the margin of the upper unduly toward the toe end of the shoe. In this operation the slide I4 is locked against rearward movement by the teeth on the members 6 and 34 to prevent any bodily rearward displacement of the links I14. v To cooperate with the wipers I62 in wiping the upper inwardly near the ball line, and for wiping it inwardly also in locations where the bottom of the inverted shoe curves downwardly in a heelward direction beyond the ball line, the machine is further provided with additional wipers I18. Each of these additional wipers comprises a thin resilient metal plate more readily flexible than the wiper plate I68 and secured by two screws I80 to the supporting plate I56 in a position spaced from the latter plate. A por-" tion a of each wiper I18 (Fig. 9) is arranged to lie between the shoe and the plate I68 with its edge in contact with this plate but elsewhere spaced therefrom to permit it to be readily flexed in response to the pressure of the shoe thereon in the wiping operation. Another portion b of the wiper I18 xtends in a heelward direction for wiping the upper inwardly in a location where the bottom ofthe inverted shoe curves downward beyond the ball line, and this portion of the wiper has a normal curvature heightwise of the shoe somewhat less than'the' curvature of the corresponding portion of the 10 shoe bottom to insure that as it starts to move inwardly there will be suflicient clearance between it and the edge of the insole to prevent displacement of the insole. To render it properly eifective in wiping the upper over the insole and in pressing it on the insole there is provided means for automatically bending it downwardly after it has passed the edge of the insole in its inward movement. For this purpose there is secured on a lateral extension of each lever I50 a casting I82 (Figs. 2 and 3) formed to provide within it a cylinder I84 in which is mounted a piston I86. Carried by this piston is a pin I88 which extends through slots I90 in the opposite sides of the cylinder casting, the movements of the piston in opposite directions being limited by engagement of the pin with the casting at the opposite ends of the slots. A spring I92 connected to one end of the pin and to a member I94 fast on the casting I82 tends to movethe piston in an outward direction and holds it initially at the limit of its outward movementl Mounted on the pin I88 is a rod I96 which e'xtends through the open inner end of the cylinder I84 and a diametrically reduced portion of which is slidably movable in a trunnion block I98 pivot ally mounted on one arm 200 of a bell-crank lever 202, the bell-crank lever being mounted for swinging movement on a pin 204 supported in an upstanding lug 206 on the lever I50. Extending around the rod I96 between a nut 208 threaded on the rod and a flange 2| 0 on the trunnion block I98 is a compression spring 2I2, and threaded on the rod on the opposite side of the trunnion block from the spring is a nut 2I4 arranged to engage the trunnion block Pivotally connected at its upper end to the other arm 216 of the bell-crank lever 202 is a bar 218 which extends downwardly through an opening in the wiper-carrying plate I56 with its lower end in position to engage a small block 220 secured on the portion b of the wiper I18. By operative movement of the piston I86, therefore, the bar 2I8 is moved downwardly at the proper time to bend the portion b of the wiper I18 in a down ward direction and thus to cause it to press the portion of the upper which it engages against the insole.
For operating each piston I 86 fluid underpres sure is forced intothe outer end of the cylinder I84 through a conduit 222 communicating through a flexible tube (not shown) with the source of fluid supply, the admission of the fluid to the cylinder being controlled by the samevalve (not shown) which, in accordance with'the disclosure of the previously mentioned application, admits fluid to the gripper-operating means to cause the grippers 28 to pull the upper. Operative movement of the piston by the fluid,
however, is prevented until the wiper I18 has thereafter arrived in a predetermined position relatively to the shoe. For this purpose there "is pivotally mounted on a pin 224 in the casting I82 a latch 226 which initially engages one end of the pin I 88 in the piston to hold the piston against operative movement. Pivotally connected to this latch is a rod 228 extending through an opening in a bracket 230 fast on the frame of the machine. Between this bracket and a shoulder on the rod 228 adjacent to its pivotal connection with the latch is a compres sion spring 232, and threaded on the outer end portion ofthe rod is a nut 234. As illustrated in Fig. 2, the spring 232 initially holds the latch Z26 inpositi on to engage the pin I 88 and preventmovement of the piston, and the latch is held in this relation to the pin until the wipercarrying lever I50 has moved far, enough to cause the nut, 234 to engage the bracket 230, whereupon the latch is caused to release the pin in response tocontinued movement of the lever, thus causing the bar 2l8 to be forced suddenly downward. Preferably, the nut 234 is so adjusted that this downward movement of the bar takes place immediately after the wiping edge of the portion bof the wiper I18 has passed the extreme edge of the insole, so that. this portion of the wiper will be conformed to the contour of the shoe bottom and will apply its downward pressure to the upper prior to the completion of its inward wiping movement. In pressing the wiper down on the insole the spring 2l2 will yield inresponse to resistance of the shoe to the downward movement. of the bar. 2H3, the rod I 96 sliding in the trunnion block I98. When thefluid under pressure. is later released from the cylinder 84 the piston W6 is returned: by the spring Hi2, after which the latch 226 is returned. by the spring 232; toits operative positionin. response to return movement of the lever. I50. The" portion b of each wiper H8 extends farenough toward the heel end of the shoe to overlap to someextent' a portion of the upper previously lasted at the shank. portion of the shoe.
From the foregoing. description it will. be evident that thewiper Hi2 (with itsplate l-SB) and. the wiper H8 at each side of the shoe. are arranged to extend continuously, eachbeyond the other, lengthwise of the shoe,v and that the wiper [82- is moved relatively to the wiper H3 without afiecting such continuity whenit is positionedas determined by the shoe in the presentation of the shoe tothe machine. It will iur-ther be-understood that it is in consequence or such positioning movement of the wiper H52 that. the distance of the engagement. of the; pair of wipers [.62 and HQ with the shoe: lengthwise thereof is. determined in accordance with the position of the toe-end face of the shoe and will vary for shoes of difierent sizes. The wipers at each side of the shoe are maintained; in a heated condition byelectrical heating, units 236: mounted in the wiper-supporting plate I56, heat being conducted fromthis plate to the wipers.
In order torender the: portions 17 of the flexible wipers I18 properly eliective in pressing the upper down on the insole, the machine. is: provided with further means forinsuring. against any tipping of the shoe as a result. of the pressure thus. applied. For the purpose in view a plate 2387 (Figs, 1 and 4-): which is curved to present a convex upper face extending lengthwise of the shoe is: secured to rectangulanportions 239 (Fig. 4a) of a p n 240 mounted for tuming movements about an axis extending widthwise of the shoe in. the frontendsoi two parallel rearwardly extending arms 242 which arepivotally mounted at their rear endsonthe casting 18- for swingingmovements heightwise of the shoe. A spring 244iconnected to one of the arms and to a collar- 246 fast on the pin- 24! holds: the plate 238 normally in a position such as. illustrated in Fig. 1 while permitting it to be tipped about the axis of the pin 24!) in either direction. Pivotally connected at its upper end to one of the arms 242 is: a rod 248 extending downwardly through a member 2.5.0 mountedv in thecy-linder casting H. Betweenthe member- 2,50and a collar 252 fast, on, the lower end of the. rod 248 is a compression spring. 2:54; and
between the member and another such collar 258 fast on the rodnear its upper end is another compression spring 258. Through these springs the arms 242 are held in a state of balance at such a height that when the shoe is presented to the machine they will be moved downwardly to some extentagainst the resistance of, thecomparatively light spring 258 by reason of engagement of the last with the plate 238. This plate swings in one direction or the other about the axis of the pin 240 until it is seatedboth against the top. face of the back cone (or heel end). 6 of the last. and againstv the top of. the front cone d of the last, as illustrated in Fig. 4. To support the plate. firmly in the position and at the height which it thus. assumes, a hollow plunger 9.60, is slidingly mounted for vertical movement. on a stationary piston. 2.62 secured to the frame of the machine. A spring 264 connected to the plunger tendsto moveit downwardly and holds it initially in itslowest position in engagementwith a boss 2E6 on. the, frame. Through a bore 268. inv the piston 2&2. fluidunder pressure is admitted to the interior or the plunger 280 to move itupwardI-y into, supporting engagement. with a roimd portion of pin240 between. the rectangular portions 2'39 oi. the pin. Such admissionoi. the fluid is controlled by the samev previously mentioned valve (not shown) which controls. the upperpulling movements of the grippers,. the shoe at this time having already been clamped against the shoev rest members 2. and 6 by the toe rest 46. It. will be understood that the pressure thus applied to the plate 238' by the plunger. 2.60 is not. sufficient. to displace the. shoe from the. position in which it is. held. between the shoe. rest members 2 and 6 and the toe. rest.
Further to insure against any tipping of the shoe by the actionof the bars 2I8 on the flexible wiper I18 mechanism is provided for. positively locking the plunger 256 against. downwardmovement after it has been moved upwardly... IThis echanism. comprises three pawls arranged in staggered relation for engagement with ratchet teeth 2'") onv the plunger. One of these pawls 212 is fast on a pinz'l'imounted to turn in-a bearing on the cylinder casting Thand. at opposite sides of this pawLrespectively, are two other pawls 21B loose on the pin. Each. of the pawls 21B. is controlled. by a small spring. 278.connected to it and to a pin 28!) extending through the pawl 2'12, these springs holding the pawls 2-16 initially in a. relation. to the pawl 212 determined by their engagement with the pin 280, as shown in Fig. l. Mounted in the middle pawl 212 is a spring-pressed pin 282 in engagement with the casting Ti and tending to swing the three pawls toward the ratchetv teeth 219'. The pawls are held initially out of engagement with the teeth by arod 284 pivotally mounted at its upper end on a; pin: 286 in the. piston '58 and having fast thereon a collar 28.8 which initially engages an arm 29!! fast on the pin 214 and thereby holds the pawls in their idle positions. When the piston 10 is. movedupwardly to carry the toe rest it into engagement with the shoe the upward movement of the rod 28- releases th arm 29:5 and thus permits the pawls to be swung into engagement with the teeth ziil'by the spring-pressed pin 2.82 ready to hold; the plunger 2% against downwardmovement after its upward movement. In the return of the parts to: starting positions the downward movement of the piston it causes the rod 284 to withdraw the pawlsfrom the ratchet teeth, thus permitting return of the plunger 260 by thespring 264 when the fluid is released from with- I in it. Upward movement of the plunger if there is no shoe in the machine is limited by engagement of a lug 292 thereon with a stop 294.
