25 Claims. (01. 12-12) V l r This invention relates to lasting machines and isherein shown as embodied in a machine for lasting the ball portions of shoes from the toeend portions to theshank portions, the present application being'a division of a copendingapplication, Serial No. 139,407, filed on October 10, 1950. In its general organization the machine is similar to that shown in United States Letters Patent No. 2,614,275fgranted October 21, 1952 upon my application, and in some aspects the invention provides improvements in that earlier machine. It is to be understood, however, that this is only an illustrative embodiment and that the invention is not limited to the particular organization shown. p H e In general accordance with the disclosure of the above-mentioned Patent No.j2,614;,275, the

machine is provided withgrippers which grip the margin of the upper at the opposite sides of the ball portion of the shoe and pull the upper heightwise of the last, and with wipers which after, the pulling off the upper wipe its margin inwardly over an"insole on the last and cause itto adhere to the insole, the grippers and wipers andother elements oi the machine being operated by fluid pressure, v

In accordance with afeature of the invention the-machine includes novel means for varying, in the operation of the machine on shoes ofdifierent sizes, the distance lengthwise of theshoes of 'the'effective engagement of the wiperswith the shoe uppers. Forthe purpose in view the upper at each side of the shoe is operated upon by'a pair of wipersi arranged to extend continuously, one beyondvthe other, along the side of the shoe and relatively movable lengthwise of the shoe while maintaining such continuity, and through such relativemovement of the wipers the'distance lengthwise of the shoe of their engagement with the upper is determined. In the operation of the machine the two wipers of each pair'are moved inwardlywidthwise of the shoe with substantial components of bodily movement lengthwise of the shoe toward its toe end, and to effect their relative movement for the purpose above describedthat component of movement of the wiper which is nearest tothe toe end of theshoe is variably -limited independently of the movement of the other wiper. In presenting the shoeto the machine the operator positions it lengthwise, regardless of its size, in proper relation to the grippers as determined by sight with reference to the'grippers, and accordingly the toe-end faces of shoes of different sizes occupy different 'pos itionsin the machine. Conveniently,-"- therefore, a member engaging the toe-end face ofeach shoe and positioned as determined by the shoe is utilized for limiting as described the above-mentioned components of movement of the Wipers nearest to the toe end of the shoe, this member being arranged to determine variably the positions of stops which act on links pivotally connected to these wipers. A further effect of this wiper-controlling means is to terminate the engagement of the wipers with the upper at the same distance from the end of the toe of each shoe regardless of variations in the positions of the different shoes. Insurance is thus afforded'that if the shoeshave therein upstanding pulling-over tacks at the sides of the toes the wipers will not engage these tacks. In the construction shown. the above-mentioned links extend initially in convergent relation toward the toe end of the shoe and in'th operation of the Wipers they approach a parallel relation to each other. As the links, therefore,

continue to swing toward parallel relation after their movements lengthwise of the shoe have been terminated by the stops, they impart to the wipers connected therewith components of'movement reversely toward the heel end of the shoe relatively to the other wipers. This serves to counteract any tendency for thesewipers to deflect the portions of the'upper which they engage in directions toward the toe end of the shoe.

The invention still further provides novel means for operating thewipers. In general accordance with the disclosure of the previously mentioned Patent No. 2,614,275, the portions of the wipers which are farthest from the toe .end of the shoe are moved inwardly toward andover the shoe by arms'which are mounted for swin ing movements about, axes'extending heightwise of the shoe, and portions of the wipers located nearer the toe end of the shoe are at the same time moved inwardly by other arms mounted for swinging movements aboutjother similarlyJextending.'axes, the wipers being swung farther inwardrelatively 'tothe first-mentioned arms by continued movements of these other arms after the'first-mentioned arms (have come to a stop. In. the constructionherein shown novel connec tions are provided between the other arms and the first-mentioned arms for swinging thelatter inwardly by the movements of the other arms until the wipers have partiallycompleted the wiping operation and for thereafter terminating the movements orthe first-mentioned armsbut for holding them positively-against retractive movements during turther movements of the other arms to complete the wiping operation. In

the construction shown these connections inl aoeaosv elude plates movable bodily by the other arms and provided with slots in which lie rolls mounted on the first-mentioned arms, and in the course of the wiping operation these plates are swung to positions such that by reason of the relation of their slots to the ions no further movements are imparted to the first-mentioned arm's during continued movements of the other arms, the ar rangement, however, being such as to prevent positively any retractive movements of the firstmentioned arms. y I

The above and other featuresof the invention, including various novel details of construc tion and combinations of parts, will'now be more particularly described with reference to the accompanying drawings and thereafter pointed out.

in the claims.

In the drawings,

Fig. l is a view partly in right-hand side elevation and partly in section of a portion of the maam ne in which the invention is herein shown as embodied;

Fig. 2 is mainly a plan new of a idbltibh or the machine, showing the wipers and their operating mechanism, with parts section and others broken away;

Figs; 3 and 4 are views genera-11y similar to a portion of Fig. 2, but showing the parts as'they appear at different times iii the operation of the machine; and

Fig. 5 is a view partly in front elevation and partly in section, showing the grippers and the wipers. I e r e For positioning thesho'e heightwise in the machine there is prewar-ea iorwa'rdly and, rearwardly extendinglever 2 (Fig. 1) which is pivotally mounted substantially midway between its front and rear ends on a pin 4 supported in two members 6, only one or which is shown, extending upwardly at fopposite sides of the lever 2 from a substantially horizontal frame casting 8 to which they are secured. Mounted for adjustmg movement upv'var'dly or downwardly in a someway in the front end of the lever 2 is a shoe rest member H3 on the lower end of which are formed two "p'resser 'fe'et l2 spaced apart width- 'w'ise of meshes as shown in Fig. 5 and arranged to engage the insole at the ball portion or the shoe, these presse'r feet having insole-engaging teeth thereon and byr'eason of their spaced i-elation'servirfg further to position the shoe with respear to lateral upping "movement. I The member I0 is adjustable heightwi'se'hf the shoe runway to the lever 2 by of M which is threaded therein, the screw having. a head IS a portion of which lies in a not in the lever 2 to prevent upward or downward movement of the screw relatively to the lever. To assist in holding the "member ID in a djl'l's ted position there is mounted in the lever 2 'a spring-pressed pin l8 having a conical front end arranged to enter one oi another Of 'a plurality or recesses ill the head of the screw. secu ed to the upper end of the screws a member 22 contents y a universe-1 joint 24 to a .i'od zethrough' the screw is tiiined, as more fully disclosed in application Serial No. 189,407. 7

Pivotally mounted on a pin 28 in the rear end of the lever 2 at the opposite sides of the lever respectively are two downwardly extending links 30 of a toggle 32, the lower ends of these links being pivotally connected by a pin 34 to a toggle link as which is pivotally mounted at its lower end a pin 38 a casting 40 on the frame. 'Conneeted to the lever 2 and to the links 30 is a spring 42 which tends to straighten the toggle 32. Threaded in the upper end of the link 36 is a screw 44 on which is mounted a lock nut 46 in engagement with a Washer 48. This washer overlaps portions of the link 36 and of the two links 39 and accordingly limits straightening of the toggle under the influence of the -spring 42. Initially, the toggle is in its straightened position, as shown in Fig. l, and accordingly the shoe rest member I0 is held positively against any upward movement in response to pressure of the shoe thereon. V

Further to assist in positioning the shoe there is provided another shoe-rest member 50 on which are two downwardly extending bosses 52 (Fig. 2 spaced apart widthwise of the shoe and having smooth faces arranged to engage the toe end of the insole. The member 50 is of angular shape to provide a downwardly extending portion from which extends rearwardly an arm 54 pivotally mounted at its rear end on a pin 56, this pin being supported in lugs extending upwardly from a slide 58 which is guided for forward and rearward movements in a holder 60 fast on a casting 62 on the frame. Mounted in a socket in the slide 53 and abutting at its rear end against a bracket 54 secured to the casting 62 is a spring 66 a portion of which surrounds a positioning rod 68 secured to and extending forwardly from the bracket as. This spring tends to move the slide 58 in a forward direction, its forward movement being limited by its engagement with a stop 10 on the holder tit. Secured on the downwardly extending portion of the angular shoe-rest them"- ber 5%! is a piece of leather 12 arranged to engage the toe-end face of the shoe when the operator presents shoe to'the machine, and in thus presenting the 'shoe the operator will move the member'fiii and the slide 58 more or less in a rear ward direction against the resistance of the spring 66 by the pressure of the toe-end face of the shoe thereon for a purpose more particularly hereinafter explained. V

Mounted in a socket in the slide 58 is a spring 74 which tends to swing the shoe-rest member 50 in an upward direction about the pin 58 "and holds it against a roll 16 mounted on a pin 13 which is supported in the lower ends of two links 89 extending upward respectively at opposite sides of the lever 2. These links are pivotally connected at their upper ends by a pin 82 to the front end of a forwardly and rearw'ardly extendm lever 84 pivotally mounted substantially midway between its front'a'nd rear ends on a pin 86 in the upper ends or the members a. Extending through vertical slots 88 in the two links i a pin 90 supported in a member 92 which is fast on the casting 3, this pin-and-slot arrangement permitting limited upward and downward'mov'e- Inents of th links. Seou'red to therea r arm of the lever 84 is a leaf spring '94 which bears on the frontarm of the lever 2 and tends to swing the lever 84 in a clockwise direction with referen'ceto Fig. 1 as permitted by the slots 83 and the pin 90.

Threaded in the rear end of the lever "84 is a screw 96 arranged to engag the upper face of the rear arm of the lever 2 and thereby to limit any swinging movement of the lever 84 relatively to the lever 2 under the influence of the spring 94. It will be evident that by means of the -screw 96 the lever 84 may be adjusted relatively to the lever 2 to determine adjustably the position heightwise of the machine of the shoe-restmember 50 which engages the toe end of the shoe independently of adjustment of the shoe-rest mem tions.

ber I which engages the ball portion of the shoe.

While the shoe is held by the operator after it has been presented to the machine it is auto- .100 (Fig. 2) pivotally mounted between their front and rear ends on vertical studs I 02 suptreads":

ported in the casting 62. Formed on the levers I06 are gear sectors I04 in engagement withea ch otherto equalize the movements of the levers. The rear ends of the levers are in engagement with the rounded outer ends ofpistonsi I05 movable toward and from each other in a cylinder I08 formed in the casting 62. 'Bosses III) of reduced diameter formed on the inn'erends ofthe pistons provide an annular space between the pistons for the admissionv of operating fluid.

when the pistons are in their innermost posi- Fluid is thus admitted between the pistons at the proper time from the source of fluid supply. Pivotally mounted on a vertical pin I I2 supported on the front end of each lever I00 in the construction herein shown is a curved bar H4 extending substantially equal distances forwardly and rearwardly of the pin, andpivotally mounted on each end of this bar to swing, about an axis extending heightwise of the shoeis a block H6 to which is secured a strip of leather H8 arranged to engage the shoe upper. As shown in Fig. 2, the two leather strips at each side of the shoe extend toward each other beyond the blocks H6, and connected to the ends of the strips which are nearest to each other is a light spring I which steadies the blocks H6 and prevents either of themfrom swinging toov far about its connection with the bar I I4 when there is no shoe in the machine. Connected, moreover, to each lever I00 and to the bar I I4 thereon .near the pin, I I2 isa spring I22 which prevents uncontrolled swinging movement of g the bar about the pin I12 and holds it approximately in the relation to the lever I00 which it assumes when clamping the shoe. It will be evident that the foremost blocks I I6 and their leather facings .clamp the shoe at the opposite sides of its ball portion and that the re'armost blocks and their facings clamp itat the, opposite sides-of the toe. By this construction the shoe is centralized bodily widthwise and is held firmly in the position thus determined in the .desired relation to the lasting instrumentalities. For returning the levers I05 upon releaseof the fluid from the cylinder I08there is provided a spring 124 connected at one end to arearward extension 1I26 of the right-hand lever and at the other end to a rod I28 secured'in the casting 62 (see Fig. l). The connection between the spring and this rod comprises an. eye-bolt I30 and a hand nut I32 threaded thereon forfladjusting the tension of the spring. o o

7 After the shoe has been positioned laterally as above described bythe' side clamps 98 it is clamped against the shoe rest members I0 and vided' with a pair of grippers I46" (Fig. 5) arthefupper the "machine" is proranged to grip the margin of theupperrespec tively at the opposite sides of the ball portion of the shoe in locations between portions of the 7 upper previously fastened to the insole by side pulling-over tacks t (Fig. 3) and, it may be, by staples s used in lasting, the shank portion of the shoe. These. grippers and their operating and controlling means are fully described inthe copending application, Serial No. 189,407, of which the present application is a division,..and nofurther. description thereof herein is necessary.

The wipers for wiping the marginal portion of the upper inwardly over the insole after the pulling of the upper by the grippers include what may be termed. for purposes of designation, main wipers INT (Figs. 2, 3 and 4:). each of these wipers having a wiping edge arranged to extend lengthwiseof the shoe and curved to extend also inwardly widthwise of theshoeheelwardly of the ball line. Each wiper I48 is pivotally mounted at its front end to swing widthwise of the shoe about a stud I50 carried by the inner end of a bar or plate I52 secured on the upper face of-a forwardly and inwardly curved arm I54 of which it serves as an extension, the arm being mounted to swing about a vertical 'pin I56 on the'frame casting 8. By means hereinafter described the two arms I54 are swung inwardly toward the shoe to impart bodily inward movements to the wipers by forwardly and rearwardly extendi ng levers I50 which are pivotally mounted between their front and rearends to swing about studs I60 extending downwardly from the frame casting 8. Secured to each lever I58 underneath is a plate I62 having therein a slot I64 arranged to extend lengthwise of the shoe, and lying in this slot is a roll I'66 (Figs. 3 and 4) mounted on a stud I68 extending upwardly from the rear end of the corresponding wiper' 148. By. reason of the locations of the pins I56 the wiper I 33 carried by each arm I54 has'a substantial component of bodily-movement lengthwise-of the shoe. towardits toe endas it is carried inwardly by the arm, and/during. this movement of the arm the rear end of the wiper is' guidedand controlled by the slot I64, the roll I66 moving rearwardly along the slot. Through the roll, moreover, the rear end of the wiper is moved inwardly by the lever I58 as the arm I54 is swung inwardly. For maintaining the wipers in a heated condition each plate I62 has secured thereto underneath an electrical heating element (not herein shown). 1

Extending upwardly from each arm I54 in fixed relation thereto is a pin I16 having a reduced upper end portion lying in a slot I12 formed in a link I14 which is pivotally mounted on a stud I16 on the corresponding wiper-operating lever I58. The link I14 is made in two parts spaced vertically from each other, the two parts acting as one. Between'the two parts of the link is ,a plate I18 pivotally mounted on a pin I on the link. to swing relatively to the link. Formed in this plate is a slot I82 which includes a comparatively short portion I84, and a longer curved portion I06 in angular relation to each other. Lying in this slot is a roll I88 mounted on the reduced upper end portion of the pin H0. The plate I18 is controlled with respect to swinging movement about the pin I80 by a link I90 which connects it to the front end of the lever I58. This link includes a member I92 pivotally mounted on the plate I10 and a screw I94threaded inthis member and extending through "a block I96 pivotally mounted on the lever I58. An enlarged head I98 on the screw engages one side 'ofthe block I95 and a collar 2% fast on the screw engages the other side of the block. It will "therefore be evident that by turning the :screw 1'94 the "plate 178 may be adjusted about the pin I30.

From Fig. 2 it will 'be understood thatwhen the parts are in starting positions the ,1'0llII'88 "on each pin I'Ifl lies inthe shorter portion "I84 of the slot I82, this protion of .the slot being in such relation to thelink I14 that as the f-rorit arm of the lever "I58 begins to swing inwardly the link acts positively through the plate I78 on the pin I10 to swing the wiper-carrying arm 154 in an inward direction, thuscausing 'the'wiper I48 to be moved inwardlywith a component of movement toward'the'toe end of the'shoe to wipe the upper over the insole; 'B y reason of the manner in which the wiper is'controlled by the slot 184 in the plate I62 it-receives at this time no substantial swinging movement 'about'the stud I59 as it is moved bodily inward. Since the link'l'fifl is pivotally connected to 'the'lever l'58at a greater distance irom'the fulcrum of the lever than "the link I'IIi and since the link Il' l is controlled by the upper end of thetpin'Il'Il in the 'slot I'I2, the lever I58 in its swinging movement acts through the link I90 to swing the 'platel'lt progressively about the pin 1-80 in "the link. 'When the parts,

therefore, have arrived in the "positions indicated in Fig. 3, the roll I88 is a-tithe junction of the two portions I84 and I86 of the slot IBZ'in the plate. As the lever 1'58 thereaftercontinues its swinging movement it is no "longer effective to swing the arm 154, since by reason of the position of the portion I86 of the islet I82 :and the .continued swinging movement of the plate H8 about the pin I80 the plate no longer applies to the 'roll I88 any force tending to swing the 'arm I5 3 farther inward. The arm, therefore, -remains stationary while the other parts move from the positions in which they are "shown in Fig. 3 to those in which they are shown in Fig. l, the link I'M beingi'm'oved inward relatively to thepin 'ITHl and the plate H8 continuing to swing about the 'pin IL80. In this .m'annerthe wiper Mfiis swung inwardly by "the lever I58 about the stud 15:3 to complete the wiping operation, especially in locations forwardly of the ball line. 'While the arm 154 is swung no farther inwardly at this time, it is locked positively against any 'retractive movement by reason of the fact that'the slot it? in the link I'M and the portion 185 of the slot 32 in the plate I18 are in crosswise relation to each other. That is, the pin I cannot move outward along the slot I'I2 because of the position of the roll I88 in the slot I82. The construction thus provided affords insurance that regardless of the resistance of the shoe the wipers I48 will always be moved inwardly to the desired limits by the arms I53 before they are swung about the studs I56 to complete the wiping operation.

Each wiper I58 has in its lower face a recess in which is mounted .a supplemental wiper 29.2 arranged to extend nearer to the toeend of the shoe for the purpose of varying the range of action of the wipers lengthwise of'theishoe. The wiper 2B2 in'the construction shown has an arouate wiping edge of convex contour and is pivctally mounted on a pin 234 in the wiper 143 to expose more or less of its wiping edge rearward-1y beyond the wiper Me. Piyotally connected to the two wipers'202 are rearwardly extending links "the wipers will not hit these tacks.

extending upwardlyfrom a crossbar 2| 2 secured 54 (Fig. 1) "ofthe-shoe-rest member 50. As hereinbefore explained, when the operator presents a shoe to the machine he positions its toe-end face against 'the'leather facing I2 on this member and moves the member more or less in a rearward direction against the resistance of the spring '66. Accordingly, the studs 2H1 are moved more or less rearwardly by this member as determined by the position of the shoe. Springs 2H5 connected to the wipers 2B2 tend to move them in rearward directions about the pins 204 and hold them initially in positions in which comparatively long portions of their wiping edges are exposed; It will be understood that when the wipers hi8 are moved inwardly by the the arms I54 with substantial components of rearward movement lengthwise of the shoe the wipers 202 receive the same movements until the rearward movements of the links 20 6 are stopped by engagement of the studs 2m with the links at the front ends of the slots 258. Thereafter the wipers 202 receive no further components of movement lengthwise of the shoe during any further such movements of the wipers I48. In this manner the distance lengthwise of the shoe of the engagement of the wipers with the upper is variably determined in operating on shoes of different sizes and insurance is afforded that the engagement of the wipers with the upper will terminate atthe same distance from the end of the toe regardless of any variations inthe positions of different shoes lengthwise in the machine, the .position of each shoe in that respect being determined by sight with reference to the grippers. If the shoes operated upon, therefore, have at the sides of the toes upstanding pulling-over tacks t (Fig. 3), insurance will be afforded that In order to vary the distance from the end of the toe at which the wipers terminate their engagement with the upper, the crossbar 2E2 has therein a slot 2H3 through which the screw "2M extends to permit it to be adjusted relatively to the shoe-rest member 58.

By'reference to Fig. 2 it will be seen that the above-mentioned links 266 diverge from each other initially in directions toward the heel end of the shoe, and by the operation of the wipers they are swung into substantially parallel relation to each other, as illustrated in Fig. 4. Accordingly, after the movements of the supplemental wipers 262 toward the toe end of the shoe have been stopped by engagement of the studs 21 0 with the links in the manner above described, the links act :during further inward movements of the wipers, especially the swinging movements thereof about the studs I50 after the termination of their bodily inward movements, to move the supplemental wipers 262 relatively to the wipers I48 in directions toward the heel end of the shoe. This serves to counteract any tendency of the wipers 202 to deflect the marginvof the upper toward the toe end of the shoe in the wiping operation.

To afiord better insurance that the portions of the margin of the upper in locations where the bottom of the inverted shoe slopes downward heelwardly of the ball line will be properly wiped inwardly over the insole and secured to the insole by adhesion, there is provided under the front end portion of each wiper I48 an auxiliary wiper 220 (Figs. 1 and 2). This wiper includes athin 206 provided with slots208 in-which'lie studs 21-0 plate 222 formed on a block 224 and engaging ace 3,037

. s the wiper I48 in the vicinity of the stud 150. The block 224 is detachably mounted on an arm 226 which is pivotally mounted on a stud 228 on the arm I 54 toswing in directions lengthwise of the shoe. .A spring-pressed pin 230 in the arm I54 engages the outer end of the arm 226 and tends to swing the wiper 220 in a rearward direction toward the toe end of the shoe, the normal position of this wiper relatively to the wiper I48 being determined by engagement of the arm 226 with a shoulder 232 on the arm I54. The wiper 220, as shown in Fig. 1, further includes under the plate 222 a thin plate 234 which is curved to present a concave facetoward the portion of the margin of the shoe bottom on which it acts and is resiliently flexible to permit it to adjust itself to the contour of the shoebottom. It will be understood that the action of the auxiliary wiper on the shoe results from the swinging movement of the arm I54, this wiper being wedged inwardly between the front end portion of the wiper I48 and the downwardly inclined margin of the shoe bottom. The movement of the wiper 22D lengthwise of the shoe maybe stopped by the resistance of the shoe before the arm I54 completes its movement, whereupon the spring-pressed pin 230 yields to permit continued movement'of the arm I54.

The levers I58.by which the wipers are operated as above described have formed thereon gear sectors 236 in engagement with each other to equalize the swinging movements of the levers.

For operating the levers there are provided two pistons 238 mounted in a cylinder 240 formed in the casting 40, the pistons having attheir inner ends bosses 242 of reduced diameter to provide an annular space to receive operating fluid when the pistons are in engagement with each other at the limits of their inward movements. At its outer end each piston engages a pair of rolls 244 mounted on the rear end of the corresponding lever I58. A spring 246 connected to the levers I58 serves to retract the wipers and to return the pistons to their innermost positions. Operating fluid is admitted to the cylinder 249'from a pipe line 248 (Fig. 1) leading from the source of supply. The outward movements of the pistons in operating the wipers are limited by their engagement with stop blocks 250, one of which is shown in Fig. 2, these blocks being adjustable toward and from eachother by means not herein shown in detail.

When the wipers have substantially completed their operative movements the toggle '32 (Fig. 1) is broken by means hereinafter described to rev lease the lever 2 and thereby to ermit the shoe to be forced more 'firmly'up against the wipers by the toe rest I34 which is subject to the force of the operating fluid. Such release of the lever '2 permits upward movement of the shoe rest member III which is mounted on this lever and engages the ball portion of the shoe. Since the other shoe-rest member 50 engaging the toe end 'of the shoe is controlled by the lever 2 through the links 80, the lever 84 and the screw 96, as hereinbefore explained, the release of the lever 2 by the toggle also permits upward movement of the member 50. To insure, however, that adequate pressure will be applied by the wipers to the portions of the margin of the upper located near the beginning of the shank portion of the shoe, the construction is such as'to prevent the member 50 from being moved as far upwardly by the. pressure of the shoe thereon as the member 20, .For this purpose there is threadedin the frame a vertical rod 252, the lower end of the rod being located over the front arm of the lever 84 to limit adjustably as desired the upward movement of the shoe-rest member 50.

For breaking the toggle 32 to cause the shoe to be forced more firmly up against the wipers as above described, there'is provided an arm 254 (Figs. 1 and 2) arranged to engage the front end of the screw 44 mounted in the toggle link 35. This arm is fast on a short shaft 256 mounted to turn in an extension of the left-hand stop block 25!] and having fast on its lower end another arm 258 arranged to be engaged by'one of the rolls 244 on the rear end of the left-hand wiperoperating lever I 58. The arm 258 is so positioned on the shaft relatively to the arm 254 as to prevent the breaking of the toggle until the wipers have nearly completed their operative movements. Since the shaft 256 is carried by the adjustable stop block 250, the proper time relation between the termination of the movements of the wipers and the breaking of the toggle is maintained whatever may be the adjustment of the stop block.

While the operation of the machine as a whole is fully described in application Serial No; 189,407 of which the resent application is a di= vision, the manner which the wipers are operf ated and controlled will be herein summarized; In presenting the shoe to the machinethe'opera tor engages its toe e'nd face with the leather facing I2 on the shoe' rest member 50 and by such engagement moves this member in a rearward direction until the margin of the upper at the sides of the ball portion of the shoe is in proper relation to the grippers I46 as determined by sight. By the movement thus imparted to the shoe-rest member 50 the studs ,2I0 (Fig. 2) are adjusted to positions for properly determining thereafter the limits of movementlengthwise of the shoe of the supplemental wipers 202.

The shoe having thus been presentedgtheside clamps 98 are moved'inwardly to clamp and position the shoe between them, the ,toe rest I34 is moved upwardly to clamp it against the shoe'rest members I0 and 50, and the grippers are operated to pull the upper, all as disclosed in the lastmentioned application. After the pulling of'the upper by the grippers the fluid is admitted to the cylinder 240 (Fig. 2) for operating the wipers. By the. resulting inward swinging movements of the front arms of the levers I53 the wipercarrying arms I54 are swung inwardly'through the action of the links I14 and the plates I'IB which connect the levers to these arms. The directions in which the arms I54 are thus moved is such that the main wipers I 48 and the supplemental wipers 202 have substantial components of movement lengthwise of the shoe toward its toe end as they are moved bodily'inward, the rolls I 66 on the rear ends of the wipers. I48 moving rearwardly along the slots I64 in the plates I62 carried by the levers I58 and the rear ends of these wipers, along with the supplemental wipers 202, being moved inwardly through these plates simultaneously with the swingingof the arms I54. The components of rearward movement imparted to the supplemental wipers 202 at this time cause the links 206 to move rearwardly until stoppedby the studs 2H] which thereby determine the limits of the rearward movements vofthe supplemental wipers. Substantia'lly at the time when the wipers arrive in positions to act on .the upper the grippers are opened to release the upper. I

The first portion of the wiping operation of the Wipers on the upper is effected by the abovedescribed bodily movements thereof widthwise and lengthwise of the shoe, the auxiliary wipers 220 at this time being wedged yieldingly inward by the swinging oi the arms I54 between the wipers M8 and the portions of the bottom of the shoe which are inclined downward heelwardly of the ball line. When the wipers have arrived substantially in the positions illustrated in Fig. 3, at which time the wiping operation has been substantially completed heelwardly of the ball line but only begun in locations nearer the toe end of the shoe, the swinging of the arms I54 ceases by reason of the relation of the plates I18 to the rolls I83 while the front arms of the levers I58 continue their inward swinging movements. In response to such further movements of these arms the wipers I48, together with the supplemental wipers 202, are swung inwardly about the studs I50, located at this time substantially at the heelward end of the ball portion of the shoe, through the action of the plates I62 on the rolls I66, thus completing the wiping operation as illustrated in Fig. 4. plained, the arms IE4 are, through the action of the plates I18, locked at this time against any retractive movements. As the wipers are thus swung inwardly the links 206 approach a parallel relation and thereby impart to the wipers 202 short heelward movements relatively to the wipers Hi8. Substantially at the end of the wiping operation the toggle 32 (Fig. l) is broken by the arm 254 to release the lever 2 and thereby also to release the lever 84. This permits the shoe to be forced more firmly up against the wipers by the toe rest I34 to increase the pressure of the wipers on the margin of the upper. Since the rod 252 permits at this time only a very short upward movement of the shoe-rest member 50 which engages the bottom of the toe end of the shoe, while the shoe rest member I!) engaging the ball portion of the shoe can move farther upwardly, the tendency of the toe rest is to rock the shoe in the direction to raise its heel end and thus to insure that adequate pressure will be applied by the wipers to the portions of the margin of the upper near the beginning of the shank portion of the shoe.
