MACHINE FOR SHAPING nrrnlts ovnn'LAs'rs.

Application filed March 16, 1923, Serial No. 625,592. Renewed February 2, 1927.

This invention relates to machines for use inthe manufacture of boots and shoes for shaping the upper materials, and is herein illustrated in its application to a well known 6 type of bed lasting machine and more particularly as applied to means for shaping the toe portion of the upper materials. It will be recognized, however, that in many of its aspects the invention is not limited to a machine of the type shown nor restrictedto theshaping of the toe end of the upper.

'In one important aspect the invention relates to the positioning of lasting mechanism in relation to the shoe, and a feature of the invention consists of a novel organization of power-operated mechanism for effecting relative movement of lasting mechanism and a shoe with means for controlling said power mechanism as determined by each particular shoe. The machine herein shown comprises power-operated means for effecting in a predetermined manner relative movement of a shoe support and lasting mechanism heightwise of the'shoe to accomplish what is usuallytermed theupwiping of the upper and relative movement thereafter to wipe the upper inwardly over the bottom of the shoe, and includes in its organization a device controlled by engagement with the bottom of the shoe for set ting the power driven parts in such'a manner as to insurethe termination of'the upwiping operation with the lasting mechanism in proper position for'the overwiping operation without loss of control of the upper.

In accordance with a further feature, the invention provides means for insuring that the lasting; mechanism will operate uniformly on different shoes, the construction shown comprising means for bringingthe wipers into engagement with the shoe at the same predetermined distance from the plane of the shoe bottom in operating on different i shoes. While this feature of the invention is not limited to a power-operated organization, it has important advantages in a machine where the wipers are closed automatically about the toe at a. predetermined time in the cycle to effect the upwiping operation, since it insures that the wipers will not enthe shoe so far from the plane ofthe shoe bottom as to interefere with their proper conforming action in the relative upwiping movement of the shoe and the wipers. In the illustrated embodiment of the invention regulation of the extent of the upwiping, together with the proper positionmg otthe wipers at the end of the upwiping as-liereinbefore explained, are effected by cooperating mechanisms one of which imparts to the wipers an invariable movement heightwise of the shoe in operating on different shoes while the other is adjustably variable as determined by the particular shoe to determine the distance from the plane of the shoe bottom at which the upwipmg operation begins and consequently the positionof the wipers relatively to the plane of the shoe bottom at the end of the upwiping operation.

A further feature of the invention consists in novel organization in which lasting or wiping mechanism which is yieldable in response to resistance of the shoe before it is moved inwardly over the bottom of the shoe is differently controlled in such inward movement, the construction shown comprismg'spring means permitting the wipers to yield in conformity tothe shoe in the up wiping operation together with locking means which actsboth to prevent further yield and also to prevent reaction of the spring means in the overwiping operation. This feature is herein illustrated in its application to wiper operating means includin'g separate springs for controlling the advance and the closing of the wipers, with looking devices associated with the different springs to afford positive control as the wipers are advanced and closed over the bottom ofthe shoe. By thus preventing reaction of the spring means which controls engagement with the shoe in the upwiping operation insurance is afforded that the wipers will not he suddenly projected over the bottom of the shoe or moved inwardly farther than would be desirable, for example in lasting a shoe of the welt type, and by eliminating further yield of the spring means in the overwiping operation better control of the wipers is afforded to insure that they will be moved inwardly the precise distance desired. While the construction shown thus combines both these advantages, it will be recognized that the invention is not limited to an organization in which the yielding means is controlled in the particular manner illustrated.

styles and sizes. In the construction shown the desired result is accomplished by the provision of means for varying relatively therates of the advancing and closing movements of the wipers. It is Well understoodithat the amount of angular closing movement of end embracing wipers required to force them inwardly a given distance from the edge of the shoe bottom at the sides of the shoe, for the same amount of advancing movement lengthwise of the shoe, depends upon how nearly the sides of the shoe approach a parallel relation to the longitudinal median line of the shoe, a greater proportional amount of such closing movement being required on narrow pointed toes than on comparatively round toes. In the use of prior constructions having means for imparting to wipers predetermined advancing and closing movements it has been possible only to effect a rough approximation to conditions which are desirable for the best results, and for wide variations of styles or shapes it has been necessary to substitute be readily adapted, for example, to operate on welt shoes or McKay shoes.

A further feature of the invention con sists in novel means of control to enable the operator to produce different results in the operation of the machine, the construction shown comprising means to determinedifferent stopping positions of the operating mechanism, together with a manually operated controlling member which is movable to different positions to determine in which of the stopping positions the machine will cometo rest and also to determine how long the machine will operate before it comes to r a stop. More particularly, the construction illustrated provides for stopping the machine with the wipers located either in the tion to the shoe.

between the difl'erenttrains of mechanism, the extent of movement required of either position which they occupy at the end of the upwiping movement or in the position which they occupy when the upper is to be fastened, for example by wiring or tacking, and further provides for such control that the machine may be made to operate through its entire cycle any selected number of times.

Still another feature consists in a novel construction and arrangement of means'for imparting operative movements to the lasting mechanism or wipers. In its embodiment of this feature the machine shown is provided with separate and operatively independent trains of mechanism for imparting respectively to the wipers their advancing and closing movements, such mechanism including power transmitting elements so constructed as to maintain a continuous operativerelation to the wipers in different positions of the wipers which they-assume,

for example, as a result of their operative n'iovement heightwise of theshoe or of adjustments to position them correctly in rela- By reason of the relation of them to effect the proper operation of the wipers is not affected in any degreeby the extent of movement of the other. This greatly facilitates the design of the operat ing parts -or cams, permits the position of the wipers lengthwise of the shoe and their relation to each other to be readily varied independently by adjustment of the respective trains of operating mechanism, and prevents the relation of the wipers to each other from being disturbed by any bodily yield of the wipers lengthwise of the shoe that may occur in the upwiping operation. I

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

The machine comprises generally a suitable lrame 20 upon which is mounted a shoe supporting jacl'; 22 and a toe rest 24 for an assembled last and shoe in the position shown in dotted lines in Fig. 3. The heel seat 01' a shoe supported by the jack 22 is arranged to be lasted by suitable mechanism indicated generally at 26. Power may be supplied to the machine by means of a belt driving a pulley 28 (Fig. 1) which is arranged to run continuously and which is connected to the jacking mechanism by a suitable one-revolution clutch controlled by a knee lever (not shown). These parts may be, and illustrated as being, the same as parts more fully illustrated and described in Patents Nos. 1,018,477, granted Feb. .27,

1912; 1,390,755, granted Sept. 13, 1921; and 1,373,482, granted April 5, 1921, all on applications of Matthias Brock. The jacking mechanism! is released, after a shoe has been lasted, in response to a second operation of the knee lever, as fully described in said patents.

Vipers 30 are arranged to be operated by powci drivcn connections, hereinafter de' scribed, lt'or upwiping and overwiping the toes of shoesheld by the aboveedescribed jaclting mechanism. These wipers are secured in carriers (Fig. (3) arranged to be moved angularly in a head or carrier 34, to close them about the end of a shoe, by pinions b6 meshing with rack teeth formed on the ct ges oi the carriers. The pinions 36 are operated by a pair of racks 38 engaging an equalizing pinion 40 mounted on a sliding rod or plunger 42.

The head 34 carrying the wipers and wiper carriers is integral with or secured to an inner sleeve or plunger 44 surrounding the plunger 42, the sleeve 44 being longitudinally D'lUVflblG, to advance andretract the wipers, in an outer sleeve 46 which is formed as part 01 ahead 48 pivotally mounted on a shaft 50 (Fig. 3). The head. 48 may be tilted about shaft 50 in alining the wipers with the bot tom of a shoe by manipulating a handle 52 as described in the above-identified Brock patents.

Shaft 50 is carried by a slide 54, which may be angularly adjusted on a. slide 58 about a vertical axis passing adjacent the toe rest by manipulating a hand wheel 56, in such a manner as to turn the wipers in. a horizontal plane to aline them. with the median line of the forepart of the shoe. Slide 58, in turn, is mounted on a second slide 60 by av dovetail connection, for horizontal movement laterally of the machine, and is arranged to be automatically operated dur* ing the operation of upwiping the shoe as described in said Patent No. 1,390,755. Slide 60 and the parts carried thereby are ar- 'holddown against the shoe by a link 96 operi i ranged for adjustment longitudinally of the machine on a head 62 carried by a Vertical slide (54, a hand wheel 66 being provided for facilitating such adjustment.

The wipers 30 may be tilted about an axis 7 attending longitudinally of the machine, to aline them transversely with the shoe bottom, by manipulating a handle 68 to turn a threaded bolt-70 carrying a traveling nut T2 connected by a link 74 with a shaft 76 seat- 7 ing in a recess in the head 34.

The shoe is held clamped against toe rest 2-1 by a holddown 80' mounted on an arm 82 which in turn is carried by a sleeve 84. Sleeve 84 is arranged to swing about a re so duced central portion of an inner sleeve 86 threaded on a vertically sliding rod 88 and arranged to be turned by a suitable handle 90 to adjust the position of the holddownby raising or lowering it relatively to rod 88. Sleeve 86 is held in adjusted position byengagement of a spring pawl 92 (Fig. 3) carried thereby with a ratchet 94 mounted on rod 88. Rod 88 is operatedto lower the ated by a tr eadle 98, which is. held down by a pawl and ratchet and which is released after the shoe has been lasted by a push rod connected to the pawl and ratchet and to the jacking mechanism, and also to a special pawl-releasing device,as described in the said Brock patents.

A bracketllO is clamped on the lower end of rod 88 in predetermined relation to the position of holddown 80 and is formed with a vertical recess which is T-shaped incross section and in which a rack block 112 is mounted for vertical adjustment. As will be explained, rack block 112 operates to vary the position of power driven connections for raising and lowering slide 64 according to the verticalposition of holddown 80 when clamped against a shoe, so that vertical movement of slide 64 in upwiping the shoe is limited in such a manner as to position the wipers 30 in predetermined relation to the plane of the shoe bottom. Rack block 112 is arranged to be adjusted vertically by a belt 114 threaded through a vertical re cess in said block and journaled at its lower 115 end in bracket 110 to prevent it from moving vertically relatively to the bracket. Bolt 114 is connected by a universal joint 116 to a telescopicshal't 118 which is connected to the vertical adjusting device operated by 120 handle 52 for tilting wipers 30 about shaft 50. By this arrangement adjustment of the wipers by manipulation of handle operates through telescopic shaft 118 to raise or lower rackblock 112 in its bracket 110 in 195 such a manner as to compensate for changes in the vertical position of the wipers due to such adjustment.

Each block 112 meshes with a sector 120 mounted on arock shaft 122 which carries Zea an arm 124 connected by a link 126 to an arm I 128. pinion 180 meshing with a rack 132 formed on, or secured to, the lower end of the vertically 'moving slide 64. The pinion also meshes with a second rack 134 which is stationary during the early portion of the operation of the machine. The lower end of arm 128 carries a sliding block or roll arranged for movement in a curved slot 136 of a cam operated lever 138, in such a manner that movement of rack block 112 in clamping the holddown against a shoe operates through arms 124 and 128 to change the effective length of the lever without moving the pinion 130. Lever 138 is arranged to rockabout a shaft 140 mounted in arms 142 and 144 (Figs. 3 and carried by the machine irame. Then the lever is rocked about shaft 140 by its cam, hereinafter described, it 01 erates through arm 128 to move pinion 130 upwardly. The pinion rolls on rack 134, which is at this time stationary, and therefore operates through rack 132 to move slide (34 and the parts carried thereby upwardly a variable distance according to the ell'ective length 01 lever 138 to position wipers 30 the same predeter-' mined distance below the plane of the bot tom of each shoe before the wipers are closed about the toe for the upwiping operation. Insurance is thus ailiorded that, what" ever may be the vertical position of the toe,"

the wipers will not engage the shoe too far from the plane of the sole for the best results in the upwiping oi the upper materials.

Lever 138 is operated and continuously controlled by .a face or path cam on one side of a cam member 146 (Figs. 3 and 4).

mounted on a cam shait't 148 journaled in arms 142 and 144 of the machine frame.

Cam shaft 148 is arranged to be driven,

under the control of the operator, "from pulley 28 by worm 150 (Figs. 1 and 4) meshing with a worm wheel 152. The worm wheel is connected by spring pins 154 with one member 01, a Horton clutch 156, of well-known construction, so that in case the machine jams the spring pins 154 will slip and the driving mechanism will not be injured. 'lVorm wheel 152 is loosely mounted on shaft 148 and only drives the shaft when it is connected thereto by manipulation of the Horton clutch 156. This clutch is formed with two disks 158 (Figs. 2 and 4) secured together, one of which is formed with a stop a or abutment to be engaged by a controller 160 and the other of which is formed with two similar stops 5 and a or abutments to be engaged by a controller 162. Controllers 160 and 162 are of the type which is ordinarily used for controlling a Horton clutch, and are mounted on the ends or the longer arms of a 3-arm This armv carries at one end a lever 164.. This lever is carried by a bracket extending from the machine frame and is operated by a link 166 connected to a bell crank lever 168 loosely mounted on shaft 122, the bell crank lever being in turn connected by a link 170 with a 'treadle 172 (Figs. 1 and 3). i r

This arrangement is such that when the treadle 172 is in its upper position (in! which it is held by a suitable spring) the 3- arm lever 164 is rocked so that the controller 162 will engage its disk 158 to disconnect the Horton clutch with the parts either in starting position or in a dill'erent position, as hereinafter more fully explained, depending upon which of the two abutments b and c on the disk is engaged by the controller. On the other hand when treadle 172 is completely depressed, the 3arm lever 164 is rocked in the opposite direction so that controller 160 engages the abutment a on its disk 158 to disconnect the clutch from cam shaft 148 with the parts of the machine in still another position. When treadle 172 is held in' an intermediate position, neither oi? the controllers 160, 162 en gages its disk 158, so that the mechanism opcrated by cam shalt 148 repeats itsjcycle of operations over and over again until the operator either releases the treadle or com-' carries a cam roll running in a cam track 8' formed in one face of a cam 184 mounted on cam shaft 148. Thus cam 184 imparts a. predetermined downward movement to rack 134 through lever to move slide 64 and the parts carried thereby upwardly a predetermined distance, after the wipers 30 have preliminarily been positioned by lever 138. Lever 138 is at'this time held stationary by a dwell in its cam so that movement of rack 134 turns pinion 130 to operate rack 132 to impart the desired vertical movement to slide 64. By this operation of rack 134 the upwiping operation is effected and during the overwiping operation (hereinafter described) the rack is yieldingly moved in the opposite direction through spring 182 to force the wipers first lightly and then heavily against the wiped-over upper materials to iron them down against the shoe bottom.

The wipers 30 are advanced and closed by independently operable connections driven from cam tracks in the faces of cams 146 and 184 which operate on cam rolls carried by bell crank levers 190 and 192, loosely mounted on a shaft 194 carried by arms 142 and 144 of the machine frame. Levers 190 and 192 are connected to a pair ofplungers 196 (Figs. 3 and 5) each of which is surrounded by a sleeve 198 which is operated by its plunger 196 through a coil spring 200 confined between. a shoulder on plunger 196 and a bushing 202 threaded in the end of sleeve 198. Each bushing 202 is formed with a knurled head 204 by means of which it may be adjusted to vary the compression. of spring 200, and a lock nut 206 is provided for securing each bushing in adjusted posi tion. Each plunger 196 carries lock nuts 208 (Fig. 5) arrangedto engage the head 204 of the corresponding bushing to move sleeve 198 positively toward the left in Fig. 5 to a predetermined initial position to adjust the wipers, as more fully hereinafter explained.

Sleeves 198 are formed with rack teeth to engage and drive pinions 210 and 212 carried by vertical shafts journaled in arms 144 and 142 of the machine frame. These arms are extended downwardly to form a stationary casing 214 in which sleeves 198 may slide, and in which housings for pinions 210 and 212 are formed. Pinion 210 is conneoted through its vertical shaft by a universal joint to a vertical telescopic rock shaft 216 and similarly pinion 212 is arranged to drive a telescopic rock shaft 218.

At its upper end rock shaft 218 is connected by a universal joint to a rock shaft 219 journaled in a pair of arms 220 integral with or secured to the head 48 supporting wipers 30 and their operating. mechanism. The rock shaft 218 is formed in two relatively rotatable parts (Figs. 3 and 6) the lower part carrying an arm 222 which seats against an arm 224 carried by the upper part; and the rock shaft 219 has fast thereon a toothed segment 226. When arm 222 is rocked to the right in Fig. 6 it operates segment 226 by direct engagement with arm When it is rocked to the left in that.

figure it operates the segment through a coil spring 228 engaging an adjustable head 230 on a bolt 232 which passes loosely through openings in arms 222 and 224 and T is formed with a fixed head to engage arm Segment 226 is in driving engagement with a rack 234 carried by an arm extending.

from a sleeve 236 surrounding a reduced portion formed on the sleeve 44 which carries head 34. Thus head 34 is moved back and forth to advance and retract wipers 30 by rock shaft 218 operating through rack and segment 226 and 234. Sleeve 44- is free to turn, in sleeve 236 and the latter is mains tained in a horizontal position regardless of the angular adjustment of sleeve 44 by means of'upperand lower guide flanges 238 slidingly engaging rack 234.

toclr shaft 216 is connected by a universal joint 'to a rock shaft 239 journaled at its upper end in a pair of arms 240 formed as an extension of sleeve 236 so as to move back and forth with sleeve 44 while being maintained in a horizontal position by guide flanges 238. Similarly to the rock shaft 218, the shaft 216 comprises two relatively rotatable parts, of which the lower part carries an arm 242 engaging an arm 244 carried by the upper part; and there is fast on the rock shaft 239 a toothed segment 246. Arm 242 operates the segment by direct engagement with arm 244 when rocked to the right in Fig. 6 and when it is rocked t0 the left it operates the segment through a spring 248 surrounding a bolt 250 which passes through openings in arms 242 and 244. The bolt is formed with a fixed head seating against arm 242 and with an adjustable head 252 engaging spring 248.

Segment 246 is in driving engagement with a rack 254 formed on an extension of a sleeve 256 mounted on a reduced portionof the rod or plunger 42. which is operated thereby for opening and closing wipers 30. Sleeve 256 is retained in its place on the reduced end of the rod or plunger 42 by a head 258 and is kept from turning when rod 42 is angularly adjusted with sleeve 44 by guide flanges 260 carried by arms 240 which are in sliding engagement with the upper and lower surfaces of rack 254.

Springs 228 and 248 are quite heavy, as they are not expected to yield during the normal operation of the machine. If, however, for any reason the wipers do not clear the last bottom before the beginning of the overwiping operation, these springs can yield to prevent damage.

By this arrangement it will be observed that operation of rock shaft 218 for advancing. and retracting the wipers has no effect on the opening and closing. of the wipers, as it merely carries arms 240 and the shaft 239 idly back and forth and therefore swings the top of rock shaft216 backward and forward without any operative effect upon it and thus without affecting the relation of the wipers to each other. On the other hand, operation of rock shaft 216 is independent of the longitudinal position of sleeve 44, and operates to open and close the wipers without having any efiect on their advancing and retracting movements. The different trains of mechanism leading from. the operating shaft to the wipers for advancing and for closing the wipers respectively are thusv operatively independent of each other; that is, the extent of movement required of either train of mechanism properly to perform its lengthwise of the shoe inthe upwiping op eration has no effect upon the relation of the Wipers to each other. The vertical movements of slide 64 have no effect, either on the closing or the advancing movement of the wipers, due to the use of telescopic shafts and universal joints as parts of the operating connections. I

.While not limited to such use, a construction such as above described may adv-an tageously be modified as illustrated in Fig. 7, or in an equivalent manner, to vary the amount of advancing and closing movements of the wipers, or so that the amount or rate of closing movement which corresponds to a given advancing movement, or vice versa,

may be changed to suit the particular shoe being lasted, So far as I am aware, in all previous machines this ratio has been fixed, and in order to make such a change it has been necessary to remove some of the parts of the machine and replace them by others. In the embodiment of this feature of my in vention illustrated in Fig. 7, bell crank levers 190 and 192 are connected to their-respective plungers 196 through links 270.. Each of these links is pivotally connected at one end to its plunger 196 and at theother end to a block 272 threaded on an adjusting device 274twhich is carried by lugs 276 and 27 8' on bell crank lever 192 (or 190) in such a manner that the adjusting device is restrained against longitudinal movement. Each of the adjusting devices-27 i is formed with a knurled head 280, by means of which it may be manipulated. turning either of the heads 280 the corresponding block 272 is moved up or down to change the effective length of the bell crank lever by which it is carried, in such a manner as tochange the extent of movement of plunger 196 corresponding' to the throw imparted to the bell crank lever by its cam 146 or 184.

This arrangement is entirely new so far as I am aware, and is useful in changing the machine over from welt to McKay work or vice versa, inasmuch as it is necessary to advance the Wipers farther and at the same time toclose them farther in overwiping Mc Kay shoes than isnecessary or desirable with 'welt shoes. This novel arrangement 15 of even greater utility in adjusting for different sizes and styles of welt shoes or McKay shoes as the case may be. It is desirable to wipe in at opposites ides of the toe of'a shoe, approximately at the ends of the tip seam, substantially the same linear distance as the wipers simultaneously move forward over the end of the toe, to provide as nearly as possible for uniform wiping action ontirely around the toe. Obviously the amount of angular movement of the wipers neces-, sary to produce this result, for a given amount of advancing movement, depends upon how nearly the sides of the toe approach a relation parallel to the longitudi-v nal median line of the forepart of the shoe, and consequently a greater angular movement of the wipers is necessary, for the best results, on some shoes than on others, for example on pointed toes as compared with round toes. Heretoforc it has been necessary, unless the machine was actually changed over by replacing various parts, to design the machine to impart a definite closing movement to the wipers for each increment of advance, in such amanner as to operate most efliciently on a shoe of average size and style. his sort of a compromise has been found to work very well on many kinds of work, but does not permit of securing the extreme accuracy that is possible with the abovedescribed arrangement, which provides for adjusting the machine for each change in the size or style of shoes.

In addition to the above-described adjustments for varying the rate or extent of either the advancing or the closing movement of the wipers, the nuts208 in cooperation with the sleeve 202 and the spring 200 of the wipenadvancing mechanism may be utilized to adjust the Wipers initially lengthwise of the shoe withoutaffecting their relation to each other, and similarly the corresponding parts of the wiper-closing mechanism may be utilized to adjust the wipers toward or from each other without affecting their position lengthwise of the shoe.

It is desirable to render springs 200 in effective, during the overwiping operation, to prevent on the one hand any yielding of wipers 30 during that operation, and on the other hand to prevent the springs, which at that time have been tcnsioned by engagement of wipers 30 with the end and side face-s of the shoe during theupwiping operation, from projecting the wipers suddenly inward over the shoe bottom. To attain these ob jects each of the levers and 192 carries i ea a latch 284 so positioned as to engage a rack j i 286 carried by sleeve 198, the rack being formed to prevent movement of the latch in either direction. Each latch 28% is held out of engagement with its rack during the upwiping operation by a guard member 288 'adjustably secured to casing 214. the guard 'member engaging a pin 290 carried by the latch as shown inFigzfi. At the conclusion of the upwiping operation, the bell crank levers 190 and 192 have been rocked forward to such positions that the pins 290 ride down lit) to a thinner portion of the guard members 288, the latches thereby being permitted to engage their racks and lock plungers 196 and sleeves 198 together during the overwiping operation, thus rendering springs 200 in effective.

In the operation of the machine described above, a pulled-over shoe and its last are placed in the machine, as shown in dotted lines in Fig. 3, the jacking mechanism is operated, and the heel seat is lasted, all as is usual with machines of the bed luster type. Either before or after the lasting; oi? the heel seat, holddown 80 is swung over the tlorward part of the shoe bottom and clamped thereagainst by manipulation of treadle 98. This operation ac s tliirough rack block 112 and link 126 to swing arm 1.28 in such a manner as to vary the etlective length of lever 138 according to the vertical height of the shoe bottom. \Vipcrs 30 are adiuste fl by manipulation of handles 52, and G6 to aline them with respect to the shoe bottom and to position them angularly and lengthwise in proper relation. to the toe, and aiiljusting de vices 274 (Fig. 7) are set it this is necessary. Manipulation of handle 52 operates through telescopic shaft 118 to change the position of rack block 112 in such a manner as further to vary the effective length oi lever 138 to compensate for any change in the vertical position of the wipers.

Treadle 172 is arranged to control the Horton clutch by moving the E arm lever 164:

to bring controller 160 or 162 into position to-engage one of the stops at, b, or a, or to avoid engaging any of the stops, in such a manner that if the treadle depressed and immediately released, sl'iatt 14B is turned far enough to operate lever 138 to bring wipers 30 up to a position a predetermined distance below the shoe bottom, as hereinbeitore explained, to operate levers 190 and 192 to advance the wipers and close them yieldingly about the end oi the shoe, and to operate lever 180 to raise the wipers to the level oi? the shoe bottom to upwipe the toe under such yielding pressure. whereupon the machine comes to rest, by reason of the action of the con trollcr 162 on the second stop on its clutch disk, to permit arrangement of the upper materials prior to the overwiping operation by manipulation of a hand pincer or otherwise, and to permit inspection of the work to determine if the wipers are properly positioned in relation to the shoe bottom. Cams 14:6 and 184; are so formed that the remainder of the revolution of shaft 148 serves further to rock levers 190 and 192 first to wipe inwardly over the shoe bottom to an extreme position. then to withdraw almost to the edge of theshoe bottom and then again to wipe inwardly to tacking or wiring position, and finally to return all the parts to their initial positions. Dnringthe overwip ing operation lever 180 is operated by its cam yieldingly to pull wipers 30 first lightly and then heavily down againstthe shoe bottom as the wipers move inwardly. to iron the upper materials down upon the shoe bottom, while on each of the retractii'ig movements of the wipers this lever is rocked quickly to release the pressure on the wipers and to lift them so as to prevent them from dragging the upper materials backwardly. To complete the cycle in this manner, the operator will preferably depress the treadle 172 to its lowest position, and with the treadle held or latched in this position the machine will perform the overwiping operations as above explained and the controller 160 will act to stop the machine with the wipers in position to permit the tacking or the wiring of the toe, depending upon whether the shoe is a hilt-Kay shoe or a welt shoe. Release of the treadlc will then cause the parts to return to their starting positions. where the machine is stopped by the action of the controller 162 on the first abutment of: its clutch disk. The operator will then push on the usual knee lever to cause the jacking: mechanism and the holddown to release the shoe.

As an alternative to the above-described manner of operation, the operator may at any time, if he desires, render the machine continuously operative by moving the treadle to an intermediate position and holding or latching it in that position. This may be done after the machine has been stopped at the. end of the upwiping operation, in which case the wipers will perform the over wiping operations and will then retract and repeat their entire cycle of movements, including both the upwiping and the overwiping operations, as many times as the operator may desire. By properly positioning the treadle, the operator may then cause the machine again to come to a stop at the end of the upwiping operation or in position for the tacking or wiring operation. On the other hand, the machine may, at the start, be rendered operative, upon a full depression oi the treadlc, to pert-arm the upwiping and then the overwiping operation and to come to a stop in position for tacking or wiring, or by moving the treadle at once to an intermediate position the machine may be caused to go through its entire cycle with out a stop and to repeat the cycle one or more times before coming to a stop in any one of its normal stopping positions as may be determined by the ope ator.

It will be observed that the wipers are moved preliminarily by a shoe-controlled device hcightwise of the shoe a distance depending upon the height of the toe and. which may be different for different shoes, so that they are closed about the end of each shoe a predetermined distance below the shoe bottom. By this arrangement the upwiping operation on all shoes is carried out in a predetermined manner Without special attention from the operator. lVipers 30 are yieldingly, closed about the end of the shoe after they have been thus positioned and are held thereagainst during the upwiping operation through the medium of springs 200 so that they may adjust themselves to the contour of the shoe, which is different at different levels, and may yield either length-' wise or laterally of the shoe, and at the conclusion of the npwiping operation they have therefore automaticallybeen adjusted to the contour of the edge of the shoe bottom. At this time the latches 284 operate to render springs 200 ineffective and during the overwiping operation the Wipers are controlled in a predetermined manner and substantially positively by cams 146 and 184, While at the same time the Wipers are yieldingly depressed in a predetermined manner by the operation of cam 184 on lever 180.
