NEWJERSEY, A CORPORATION 01E NEW JERSEY v f MAoHIn non OPERATING on sirens Application filed Ma a, 1930. Serial No. 454,095.

This invention relates to machines for operating onshoes, and is herein illustrated in its application to a machine particularly adapted for lasting the heel ends of turn.

shoes of that type in which the upper materials at the heel end are sewed to a shoulder on the sole. It is to be understood, however, that in various novelaspects the invention is more generally applicable to machines for lasting shoes of other types and for operating on other portions of ashoe, such as'the toe end, and in some aspects also to machines for performing operations other than lasting operations.

In accordance with one important feature the invention provides novel means for positioning a shoe in a definitely determined relation to the means that operates thereon. In a machine of the character illustrated, which has end-lasting wipers that are advanced and closed definite distances to shape the upper materialsagainst a shoulder on the sole, it is important that different shoes be positioned eachin the same definitely determined relation to the wipers, in order to insure that the edges of the wipers at the limit of their operative movements will apply to the upper ma terials suflicient pressure to shape them as required. In operating, as herein shown, on

the heel ends of turn shoes, suchadefinite relation between each shoe and the wipers is necessary in order to insure that the heel end portion of the upper materials, including the comparatively stiff counter, will be shaped in the angle between the shoulder and the margin of the sole'in such manner as to PIOVldQ'l good crease-to receive the stitches in the sewing of theupper materials a to the sole. As applied to an organization having a shoe support that is movable to present the shoe infl position to be operated upon, the invention, in one important aspect, accordingly provides means that is movable A with the shoe support for determining by engagement with theheel'end face of the shoe and with a relatively fixed portion of the machine the lengthwise position of the shoe.

More particularly, as illustrated, the shoe support carries gage mechanism including a member that contacts With the heel end face of each shoe after the shoe and its ast ma been mounted on a last pin or spindle; on the support, and the machine is provided with an abutment arranged to contact with the gage mechanism to limitthe movement of the shoe support, so that the" heel end face of every shoe is positioned in the same location regardless of any variation that there may be in the locations of the spindle holes in different lasts. In a further novel aspect also the shoe support, which is' so constructed as to permit lateral movementof the shoe in response to pressure applied on either'of its" opposite side faces, is provided with mem bers for. centralizing the shoe laterally ,by-

engagement with the side faces of its heel end portion, so that the lateral position of every shoe in relation to the Operating means or wipers is vdefinitely determined. The members engaging the end and side facesof the shoe as described have a clamping action on the upper materials, including the counter, which assists in positioning the materials close to the last in preparation for the action of the wipers; and novelty is also, to belrecognized in this aspect of the organization. In the construction shown the end and side gaging or clamping members are-so mounted that they are movable as a"unit lengthwise of'the shoe, whilethe side members are also movable laterally of the shoe; and the several members are so controlled that'the side members are the last-to engage the shoe in the movement of the members to. operative positions and are the first to re-'' lease'the shoe in the reverse movement of the members. As illustrated, spring uneans is provided for 'moving the members-to operative positions and a treadle for moving them reversely to release the shoe or to permit the mounting of a shoe on the shoe sup port. f Further novel features are to be recog'- nized in the disclosed organization of means for operating the'end-lasting wipers." Included among these featuresare a novel construction of means for operating the wipers wipe the upper heightwise of the shoe before wiping it inwardly over the sole, together with means for producing a final positive pressure of the wipers on the upper materials; a novel construction of means for adjustingthe wipers relatively to the shoe; and a novel construction and arrangement of means for imparting to the wipers their closing movements laterally of the shoe in combina-tion with means for advancing them lengthwise of the shoe.

The above and other features of the invention, including novel means for controlling the shoe support, novel means whereby the wipers are rendered effective to wipe the heel end portion of the upper materials heightwise of the shoe and to press them firmly against the shoulder of the sole, and various novel details of construction and combinations of parts, will now be more particularly described by reference to the ac-.

companying drawings and pointed out in the claims.

. the shoe.

relation to the shoulder d of the sole, the machine is provided with heel-lasting wipers which are operated and controlled as hereinafter described. It will be understood that, as usual in power-operated lasting machines, the wipers are advanced bodily a fixed distance lengthwise of the shoe and also receive swinging or closing movements of predetermined extent in directions-widthwise' of For positioning and supporting the shoe to receive the operation of the wipers 20, the machineis provided with'a shoe support or jack comprising a rod 22(Fig. 6) which carries at its upper end a last pin or spindle 24 adapted to enter the usual spindle hole in the heel end of the last. The rod 22 is movable upwardly and downwardly in aholder 26 in which it is mounted at its lower end,

and this holder is fast on a rock shaft 28 mounted in bearings at the base of the machine; Accordingly the rod 22 may be swung rearwardly from an initial position in which it receives the last and shoe, andmay also be raised, so as to present the shoe in proper" lengthwise and heightwise relation to the wipers.- The swinging and the raising of the rod 22 are efi'ected automatically by 1necha-- nism hereinafter described, As the shoe is raised the heel-end portion of the sole is carried into engagement with a holddown 0r gage member 30 which, except for provision for vertical adjustment, is fixed on a yokemember 31 secured on the head of the ma-- chine; I

For positioning .diflerent shoes in proper relation to the wipers for the upper materials of each shoe, hereinafter referred to generally as the upper, to be wiped inwardly against-the shoulder of the sole with the required pressure all around the heel end ofthe sole, notwithstanding such variations as there are likely to be in the locations of the spindle holes in difierent lasts, the machine isprovided with means for positioning every shoe with its heel end face in the same location, and also with means for centralizing each shoe laterally so that the opposite-sidefaces of its heel end are positioned at equal distances from a central vertical plane; For properly positioning the shoe lengthwise there is provided gage mechanism comprising a member 32 arranged to contact with the heel end face of the shoe and secured on the upper end of a yoke member or carrier 34 which has connected opposite side portions extending downwardly'andthen forwardly at opposite of the roll 40 of the gage mechanlsm with the plate 42 and that the rear end face ofevery shoe is accordingly positioned at the same distance from thefplate 42. The rearward movement of the shoe support iscompleted prior to the completion of the upward'movej ment of the rod 22, and theroll 40 therefore serves to avoid undue friction during the further upward movement of the rod and the parts carried thereby. The yoke member 84 is controlled by a spring 44 which is-mounted on a rod 46 slidable in a lug 47 on the block 38 and extending loosely through an opening in the lower front portion of the yoke member with a head 48 at its upper end bearing downwardly on this member. The spring 44 is under compression between the lug 4'7 and nuts on the lower end of the rod 46. It will thus be seen that the spring 44 tends to swing the yoke member 34 about the rod 36 so as to press the gagemember 32 against the heel end face of the shoe. To retract the 5 gage member 32 initially so that ajlast and shoe may be mounted on the pin, 24, the yoke member 84 is further controlled by means hereinafter described; V 7.

To permit the heel-end portion of the shoe to be properly centralizedlaterally,the last pin 24 is carried by a block 50 mounted for rectilinear sliding movement widthwise of the shoe in a holder 52 on the upper end of the rod 22, the holder being keyedto the rod to prevent it from turning and supported by a nut 53 adjustable on the rod. The block 50 is free to slide in the holder 52, but is limited in its movement by'a pin 54 which is fast in the holder and projects into a slot in the block. The last pin 24in the construction shown is not fast in the block 50, but is mounted on a member 56 (Fig.3) which lies in a slot in the block and can tip laterally of the shoe ,about a pin 58. (Fig 6) in the block, this member being controlled by small springs 60 at opposite sides of the pin-58. This permits the shoe to be tipped by the operator or by engagement of the holddown' member 30 with the sole to position the heel end of the sole in parallel relation to the plane of the wipers. For centralizing the shoe laterally the machine is provided with opposite side clamp arms 62 on the upper. ends ofwhich are shoe-engaging members 64' pivotally' mounted on the arms to swing about axes extending heightwise of the shoe to permit them to adjust themselves tothe The arms 62 are mounted at their lower ends to swing later-- ally of the shoe about studs 66 on the pivoted contour of the shoe.

yoke member 34 and have fast thereon intermeshing gear sectors 68 (Fig. 8) whereby the arms are required to swing equal-dis tances toward or from each other and are always maintained at equal" distances "from a central vertical plane. The arms 62 are guided by the ofiset ends of a member 70 secured on the yokemember 34, and their movements toward each other when there is armstends to swing them toward'each'other. It will be evident'that' as the members 64 on the arms 62 are pressed by the arms against the opposite sides of the heelend of the shoe, they serve to centralize it with respect to bodily lateral movement so that the shoulder of the sole at the opposite sides of its heel end will be positioned symmetrically in rela tion to the edges of the wipers 20 at the limit ofclosing movement of the wipers. A further effect of the side clamp members 64 and of the member 32 engaging the heel end face of the shoe is to press the upper materials including the counter closely about by the operation of a treadle 7 4. This treadle is pivotally mounted on a stud 7 6 (Fig. 2) on a bracket 7 8 which is secured to the holder 26, the treadle being connected bya link to a lever 82 pivoted on a stud 84 on the bracket 78. A spring 86tends to swing the lever 82 downwar ly and holds it initially in a position determined by a screw 88011 the bracket 7 8 in engagement with a lug 90 Another screw 92 serves by on the'lever. engagement with the lug 90 to limit upward movement of the lever 82 in response to the action of the treadle 74. The lever 82 is connected by short links 94 and 96 to a rod 98 which is slidingly mounted at its upper end in a sleeve member 100 pivoted at 102 (Fig; 6) to two arms-of a bracket 104 fast on V the lower frontend of the yoke member 34 Fast on the'rod 98 below the sleeve member is a collar 105 arranged to engage and lift the sleeve member as the rod is moved upwardly and thus to impart rearward tipping movement to the yoke member 34. Initially, however, the collar 105-is spaced somewhat below the lower end of the sleeve member 100, as illustrated, to provide for some upward movement of the rod 98 before it becomes effective to impart swinging movement. to the member 34, and this initial upward movement of the rod 98 is utilized to swing the'side clamp arms 62- apart. For

this purpose there is secured on the rod 98 a sleeve 106 connected by a laterally extend-j m ingrod 108 mounted in a projection 109 thereon to a sleeve 110 slidingly movable on a rod. 112. The rod 112 at its upper endfis connected to an arm 114which is fast on a.

rock'shaft116 mountedin a'bracket 118 sefast onlthe rock shaft 116 is an arm 120 con-- nected by a link 122 to an arm 124 secured to eone of the side clamp arms 62. Fast on the rod 112 is a collar 126 which is engaged by thesleeve 110 to lift the rod 112. Below the sleeve 110 is a spring 128 which serves as a yielding connection between the sleeve and le rns rod 112 in the latter part of the downward movement of the rod 98. It will be understood that when the operator releases the treadle 7 4, after a shoe has been mounted on the last pin, the spring 44'acts first to lfgswing the yoke member 34 forwardly and thus to carry the gage member 32 into pressure-applying relation to the shoewhile the side clamp arms 62 are held apart by the action of the sleeve 110 on the collar 126 to P prevent the members 64 from cont-acting with the shoe. In the further downward movement of the rod 98 after the member 32 has'engaged the shoe the sleeve 110 is-moved downward relatively to the yoke member 34 rand'thus permits the spring 72 to swing the arms 62 toward the shoe, Before the'rod 98 arrives at the limit of its downward movement deterininedby engagement of the lug 90 with the screw 88, the sleeve 110 will "usually be carried downwardly away from the collar 126 while compressing the spring,

128. In the reverse movement of the parts tornclamp the shoe the member 110 acts on the collar 126 to swing the side clamp arms apart beforethe collar 105 arrives in position to-engage and-lift the member 110 and thus to swing the yoke member 34 rear-wardly away from the shoe. Accordingly the clamp members 64 are moved out of engagement with the shoe before they are swung rear- Wardly by the yoke member, so that they are free to be swung rearwardly without rubbing on the upper materials. It will be evident that rubbing of the side clamp members on the shoe is likewise avoided by the order of movements of the di ferent members 32 and 64 in the clamping of the shoe. A further advantage in the movement of the member 32 against the rear end face of the shoe before the members 64 engagethe shoe is that this insures that the upper materials, including the counter, will be pressed for-- wardly about the heel end or" the lastbefore the clamping pressure is applied at the sides. For. imparting rearward swinging movementto the shoe support the previously mentioned rod 36 hasmounted thereon a pair of rearwardly extending rods 130 igs. 1 and 7) which are connected at their rear ends -to' a cross-head 132, and secured centrally in this cross-head is one end of a rod 133 which is-slidingly mounted in'a block 134 pivoted for turning movement ona pair of rods 136 which are fast in the frameof the machine.

7 Slidingly mounted .on'the rod 133 atthe rear of; the'block134 is amember 138 arranged to bear on one endof a spring 140which is mounted on-the rod, the spring being confined by nuts 142 on the end of the rod. The

member 138 is connected by a 1ink144 to a bellscrank lever 146 one arm of which carries azroll 148 engaged by a path cam indicateddiagrammatically at 150 and formed in one sideof a cam wheel 152. It will thus be seen that as movement toward the left (Fig. 1) is imparted to the member 138, this member acts through the spring 140 to swing the shoe support rearwardly until the roll 40 engages the plate 42, after which the spring is compressed moreor less by continued movement of the member 138. The machine is further provided with means for locking the shoe support against reverse forward movement, this means comprising three pawlsl53' which are pivotally mounted on the block 134 in staggered relation to one another and are arranged to cooperate with ratchet teeth formed on a plate 154 which is secured at one endon the'cross-head 132 and is 'slidingly mounted in a guidway in the block'134. These-pawls are controlled by a portion of the wiper-operating mechanism,

as more particularly hereinafter explained.

It will be understood that the provision for turning movement of the block 134 permits upward and downward movements of the shoe support without afiectingits relation to the means for imparting to it its swinging movements.

For imparting to the shoe support rod 22 its upward movement there is slidingly mounted." on the rod a sleeve 155 arranged to engage a collar 156 which is slidingly mounted on a reduced portion of the rod. Between the collar 156 and a member 158, which is positioned immediately below the block 38 previously referred toas fast on the rod 22, is a compression spring 160.. When the parts are in starting positions the collar 156 rests on-the enlarged portion of the rod 22 below it, as illustrated-in Fig. 6, with the spring 160 under some compression. For imparting upward'movement to the sleeve 155 there is provided a lever 162 mounted on a rock shaft 164 on the frame of the machine, the lever beingforked at one end and connected by links 166t0 the sleeve 155. At its opposite end the lever 162 is provided with a roll 168 engaged by a path cam 170 formed in one side of acam wheel 172 (Fig. 5). It will be understood that the lever acts through the spring 160 to raise the rod-22 and the parts supported thereonand thus to carry the heel-end portion of the sole of theshoe into contact with the gage member 30, after which the spring is furthercompressed by continued movement of the lever. There is further provided means for locking the rod 22 positively against. reverse downward movement, comprising a pluralityofpawls 174 which in the are arranged in staggered relation for greater precision- The .pawlsare pivotally supported on upwardly extending side portions 178 of the holder 26 and are controlled by rods 180 which are slidingly mounted'in a projection 182 of the holder 26 and in a proing limited by a collar 192 which is fast thereon and engages the projection 182. Between the collar 192 and the tail of the lower pawl is a spring 194, and'between the collar 188 and the tail of the upper pawl is a spring 196. It will be understood that upon upward movement of the rods 180 the pawls are swung yieldingly inward against the ratchet teeth through the springs 194 and 196. Such upward movement is imparted to each rod by engagement of the. projection 184 of the sleeve 155 with a collar 198 which is'fast on the rod. It will be evident that such upward movement is not imparted to the rods 180 until near the end of the upward movement of the sleeve 155, so that the pawls are not carried into operative relation to the ratchet teeth until the upward movement of the rod 22 has been substantially completed. The pawls serve to lock therod against anydownward movement during the operation of the wipers on the shoe, and early in the return of the parts to starting positions they are swung away from the ratchet teeth to permitthe shoe to move downwardly out of contact with the member 80 prior to any forward movement of the shoe support. To insure prompt disengagement ofthe pawls from the'ratchet teeth, there is fast on each rod 180 a collar 200 which is engaged by the projection-184 in the downward movement of the sleeve 155.

In case the machine is operated withoutany shoe on the shoe support, it is desirable to prevent excessive upward movement of the rod 22 such as might involve danger of breaking some part of the machine. There is accordingly secured on the front portion of the frame a plate 202 provided with spaced horizontal projections 204 arranged to cooperate with ears 206 (Figs. 1 and 2) formed on oppolte sides of the previously mentioned member 158. It will be understood that by the rearward swinging movement of the shoe support the ears 206 are carried under the projections 204, and that as the rod 22 is moved upward- I ly the projections engage these ears and thus limit the upward movement of the rod. The projections 204 are far enough above the ears 206 to prevent any limiting action in the normal operation of the machine on a shoe.

The wipers 20 are supported on a wiper carrier 208 which is guided bet-ween side portions 210 (Figs. 2 and 3) of the head of the 'machine 'formovements lengthwise of the 'shoe and. heightwise ofthe shoe.- Near its jection 184 of the sleeve 155. Each of these rods is arranged to control two of the pawls front end the wiper carrier 208 is supported by mechanism hereinafter described which.

carrier 208 is pivotally mounted. For swinging the arms 212 there is provided a bellcrank lever 218 mounted to turn on the rod 214, one arm of this bell-crank lever being adjustab-ly connected to one ofthe arms 212 and its other arm being yieldingly connected to a two-arm lever 220which is fast on a rock shaft 222. Also fast on the shaft'222 is 'a lever 224 (Fig. 1) which carries a roll 226 engaged by a path cam 228 formed in one 'side of the cam-wheel 152. The two-arm lever 220 is,

pivotally connected to a cylinder 230 in the lower end of which is threaded a sleeve member 282 slidingly mounted on a rod 284 the upper end of which is connected to one arm of the bell-crank lever 218. Between the member 282 and a collar 236 which is fast on the rod 234 is a compression, spring 238 through which movement is transmitted from the cylinder 230 to the rod-234. The'adjustableconnection between the bell-crank lever 218 and one of the arms 212 comprises a spindle 240 which is swiveled in a block 242 pivotally-mounted on one arm of the bell-crank lever and has screw-threaded engagement with a block 244 which is pivoted on one of the arms 212. Fast on the spindle 240 at one side of the block 242 is a collar 246, and keyed on the spindle at the other side of the block is a hand wheel 248 for turning it. For locking the hand wheel 248 in adjusted position there is threaded on the spindle another hand wheel 5250 whereby the hand wheel 248 may be clamped against the block 242. It ,will be understood that by turning the hand wheel 248the lever arms 212 are moved relatively to he bell-crank lever 218 and thus the wiper carrier 218 and the wipers 20 are adjusted bodily lengthwise-of the shoe to determine the limit of the advancing movement of the wipers so that they will press the-upper materialsfirmly against the shoulder of the sole at the extreme end of the shoe. The rodv234,

secured in adjusted position in a well-known the wipers lengthwise of the shoe. purposethere is a slot 252m one armof the trolled by the bell-crank lever 218.

moreover, is adjustable relatively to the bell-V crank lever 218 in such manner as to vary the amount or rate of the advancing movement of For the bell-crank lever along which a stud254 carried by the rod 234 can be ad usted and then manner. It will be evident that this adjustment, varies the effective length of that a m .of-the bell-crank lever 218 in which the slot is formed. Thismeans for varying the amount of advancing movement of the w pers, or the .rate of such movement, is useful. in combination with means hereinafter dGSCllbEd, for

similarly controlling the closing movements .ofthe wipers, to adapt the wipers for the best operation on shoes of different shapes."

It will be understood from the foregoing decription that the advancing movement of the wipers lengthwise of the shoe is effected -yieldingly through the spring 238, the yielding connection being provided largely for the reason that in the machine hereln shown the wipers are utilized to perform an upwiping operation below the edge of the shoe bottom beforetheywipe the upper inwardly against the shoulder of the sole, as moreparticular- ,ly hereinafter explained. By adjustment of the member 232 the initial compression of thespring'238 may be varied, in order to vary the pressure with which the wipers are forced yieldingly againstthe upper. It is desirable that at the end of the wiping operation the wipers shall act positively on the shoe, in order to. form a distinct crease in the upper materials, including the counter,

to provide a good sewingline. There is accordingly mounted on the rod 234 a nut 256 which is adjustableon the rod and is held inadjusted position by a lock nut 258, the

.nut :256 being arranged to be engaged by acap .260 on the cylinder 230 after-compression oflthe spring 238 so that movement is impartedpositively to the rod 234 to press the wipersfirmly against the shoe at the end *of their overwiping movement.

The pawls 153 previously referred to as means for locking the shoe support against forward movement are arranged to be con F or this purpose a'projection 262 on the lever is pivotally connected to rods 264 which are slidingly mounted in the tails of the pawls and act through springs 266 to swing'the pawls yieldingly into engagement with the ratchet teeth on the member 154 and through aoollars268 towithdraw the pawls from engagement with the teeth.

The wipers 20 are'mounted for closing ;movements-laterally of" the shoe on 'wiper holders 270 (Fig. 3) which are guided by a" curved slot in the wiper carrier 208 and are iprovide'd on their outer edges with'rack .teeth 272'engaged by cooperatingteeth'formed on rack bars 27 4 which are mounted on the wiper carrier for sliding movements lengthwise of the shoe. For operating the rack bars 274 there are provided other rack bars 276 also slidingly mounted on the wiper carrier 208 and arranged to impart movement yieldingly' to the rack bars 274 through springs 278 mounted partially within recesses in'the r ck bars 276 and arranged toengage small plates 280 which bear on lugs 282 ion the rack bars 274 or on the ends of adjusting screws 284 which are mounted in these lugs.

t will thus be seen that the springs 278 provide for closing the wipers yieldingly against the shoe and accordingly correspond in function to the previously mentioned spring 238 of the wiper-advancing mechanism. The initial tension of the springs 278 may be adjusted by the screws 284. Near the end of the wiper-closing operation the springs 278 are compressedto such an extent that the ends of the rack bars 276 engage the plates 280, so that positive closing movement is imparted to the wipers at the time when they are also advanced positively as hereinbefore described. In the return of the parts to starting positions the'racl: bars 276 engage lugs .285 on the rack bars 27 4 to return the latter and open the wipers.

lower faces in engagement with teeth formed on gear members orsectors 286, as illustrated in Fig. 4, these sectors being fast on a rock shaft 288 mounted in hearings on the wiper carrier 208. Extending downwardly arm of a bell-crank lever 294 the other arm of'which carries a roll 296 engaged by a path cam 298 (Fig. formed in one side of the cam wheel 172'. The connection between the bell-crank lever 294'and the rod 292 comprises a block 300 which is pivoted on the lever and is slidable on the rod, this block being arrangedto engage a nut 302 on the rod for imparting downward movement posit vely to the rod in the closing of the wipers. As a measure of safety the connection between the block 300 and the rod 292 for opening the wipers comprises a yieldable spring 304 interposed between the upper face of the block and a collar 306 fast onthe rod. The connection between the upper end of the rod 292 and the bell-crank lever 290 consists of a stud 308 adjustable along a curved slot 310 in the lever and adapted to be secured in adjusted position in a well-known manner. It will be evident that this adjustment serves to vary the amount of closing movement of thewipers, or the rate of their closing movement, and corresponds to the adjustment previously Therack bars .276 have raclr teeth on their described whereby the amount or rate of the advancing movement of the wipers may be .varied. The adjustable connection between the arm 289 and the bell-crank lever 290 comprises a spindle 312 threaded in a block3l4 which is pivotally mounted on the arm 289 I and swivelled in a block 316 pivotally mountscopic shaft, the other member 3240f which is .connected'by a'universal joint to a spindle .326 rotatably mounted on the frame of the machine and having fast thereon a hand wheel 328. It will thus be evident that by turning the hand wheel .328the arm 289 and v the gear sectors 286 may be adjusted relatively-to the bell-crank lever 290 to swing the wipers toward or from each other and thus to determine the limit of their closing imovements, this adjustment corresponding to the adjustment previously described whereby the limit of advancing movement of the wipers is varied. It will further beevident that the wiper-closing mechanism including the rock shaft 288'and associated parts-supported by the wiper carrier 208 is, in efiect, operatively independent of, the movement of the wiper carrier lengthwise'of theshoe, since by reason ofthe length of the link 292, its substantially perpendicular relation, to the direction of the movement of the winer carrier and the shortness of that movement, any such movement of the Wiper'carrier, either in adjusting the wipers or in operating on the shoe, simply effects an idle swinging movement of the link or rod 292 of the Wiper-closing mechanism without altering the relation of the wipers to each other.

For supporting the front end portion of the wiper carrier 208 and for moving the carrier to impart to the wipers their movements heightwise of the shoe, there is provided a rod 330 controlled by a bell-crank lever, 332 one arm of which carries a roll 334 engaged by a path cam 336 formed in one side of a cam wheel 338. Pivotally connected tothe other arm of the bell-crank lever is a member 340 which is fast on the lowerend of a cylinder342 through which the rod 330 ex tends, this member having a shoulder normaliy engaged by a washer 344 loosely mount- 7 ed on therod 330 and bearing on acollar 346 which is fast on the rod. It will thus be seen that upward movement is imparted positively to the rod. 330 through the engagement of the washer344lwith the collar 346 to raise the wiper carrier 208 and thus to impart to the wipers their 'upwiping movement; The

connection between the upperend of the rod 330 and the wiper. carrier comprises a memher 348 which is threadedon the end ofthe rod and is mounted on an eccentric-350 carried by. a shaft 352 whichis mounted in bearings on the wiper carrier 208.- Easton the shaft 352 isa wormgear 354 engaged by a worm 356 on a spindle 358 mounted ind one side of the wiper carrier this spindle havingthereon a hand wheel 360 for turn ing it. It will thus be seen that by turning the hand wheel 360 the wiper carrieri208 maybe raised or lowered relatively to the rod 330 to vary the limit of upwiping. move ment of the wipers. Ari-additional adjust ment of thesame character may be made-by turning the threaded rod 330 relatively to themember 348, a hand wheel 362 on the rod 1 being providedfor this purpose. The latter adjustment is in the nature of a setting-up adjustment and will be required infrequently.

When thewipers are positioned over the edge of the sole, downward movement is ini- 332-to increase the pressure of the wipers on the upper For this purpose there are yleldlng connections between the member 340 and the rod 330, comprising a compara tively lightspring 364 which is efi ective in parted to the wiper carrier 208 by the lever the inwardmovement of the wipers over the sole and a heavier spring 366 whichbecomes effective when the wipers have substantially completed their inward movement.

Both

these springs hear at their up er ends ona cap 368 which is threaded on thecylinder 342 and is slidable on the rod 330, the lower end of the light spring 364 bearing on the collar 346 and the lowerend of the heavy spring-366 bearing on the washer 344. Below the washer 344 is a nut 370 on the rod 330, this nut being normally spaced somewhat below the washer, as illustrated in Fig. 4. It will be evident that when the lever 332 is moved in the direction to press the wipers downwardly upon theshoe, the light spring3 64 is first yieldable by reason of its engagement with the collar 346 fast on the rod 330, the-heavier springu366 being idle 'untilthemember 340 has moved relatively to the rod 330 enough to bring the washer 344 into engagement with the nut 370. Thereafter the downwardly directed force is applied to the wipers through both springs, this action occurring substantiallygatthe. time when the advancing and closing pressures of the wipers against the upper materials become positive. H

The three cam wheels 152, 172 and 338 are .all fast on acam shaft 372. Faston thiscain 1'- shaft is a wormgear 374 (Fig. 9.) 'wl1iclris driven by a worm 376 fast on a shaft 37 8.

Mounted loosely on the shaft 37 8 is a drum 380 which may be driven either by a belt operating on a pulley 382 thereon, or by an electric motor 384 (Fig-1) which is connected to the drumthrough a train of gears 386, 388, and 390, the gear 390 being formed on the .drum itself. -At. one endthe drum 380 is so formed as to provide an internal clutchface 392 arranged to cooperate with a clutch m-ember '394 slidingly mounted on the shaft 378, this clutch member being also arranged to engage astationary brake surface 396 'when it is not in engagement with the clutch face 392. The clutch member 394 is connected to the shaft 378 to turn therewith by means of a tongue 398 which projects into a slot formed in a collar 400, the latter being pinned to the shaft. Springs 402 mounted in the hub of the clutch member 394 and pressing on the collar 400 tend to move the clutch -member into engagement with the clutch face 392. For controlling the clutch member 394 there are mounted in an annular groove in the hub of the clutch member two halves of a collar 404 connected by links 406 to a forked arm of a bell-crank lever 408 pivoted on the frame of the machine. On the end of the other arm of the bell-crank lever 408 there is pivotally mounted ablock'410 having a plate 412 thereon arranged to be engaged by the lower end of a sleeve 414 fast on a rod 416 which is pivoted at its lower end to a-treadle 418 normally raised by a spring 419 (Fig. 1). A spring 420 connected both to the block 410 and to the rod 416 tends to hold these parts in the positions illustrated in Fig. 9, in which the sleeve 414 is over a portion of the upper face of the plate 412. The position of the rod 416 is determined by a pin 422 against which the sleeve 414 is held by the spring 420, this pin being mounted in the forked end of an arm 423 fast on a rock shaft which carries also an arm 424 automatically controlled as hereinafter described. The arm 423 carries a plate 426 Which, as illustrated in Fig. 9, engages a plate 428 on the block 410 and thus maintains the bell-crank lever 408 in position to disconnect the clutch member 394 from the clutch face 392 and to hold it against the braking surface 396. When the operator depresses the treadle 418, the member 414 acts on the'plate 412 to tip the block 410 in such manner as to carry its plate .428 out from under the plate 426, thus tripping the clutch so that the springs 402 force the clutch member 394 into engagement with the clutch face 392 to start the operationof the machine. In further downward movement of the treadle the pin 422 acts on a cam face 430 on the sleeve member 414 to swing this member out frornover the plate 412 and thus permit the block 410 to be turned back to its former position by the spring 420. Such return of the block is permitted by'upward movement of the arm 423 which occurs immediately after the starting of the machine. The mechanism for controlling this arm comprises'a link 432 whereby the previously mentioned arm 424 is connected to one arm of a bell-crank lever 434, the other arm of the latter carrying a roll 436 which is engaged by a earn 438. on the cam shaft 372. This cam is provided "with two projections440' and 442, the former of which is in engagement with the-roll 436 when the parts of the machine are in starting positions. As the projectionf440 leaves the roll436 a spring 444 acts on the bell-crank heel seat and to draw it around the'heel 'end 'of the shoe under the wipers ready to pull it into'upper-holding position and to fasten it at the other side as-soonas the wipers release their pressure on the shoe. The -machine'i's'prov'ided with a support for 'a coil 446 (Fig.3) of binder wire whichthe operator may thus use'if'he desires, althou'gh it has been found that under usual conditions the :upper materials are shaped or-molded so effectively in the angle between themargin and the shoulder of the sole as-='to requireno fastening means prior tothe sewing of the upper to the shoulder of the sole. It will be understood that after the machine has-come to a stop as described, the operator will again start it by depressingthe treadle 418, and that it will be brought to a stop automatically at the end of the cycle by the action of the cam projection 440 on the roll 4-36.

The machine is further provided with means whereby the operatorm-ay conveniently bring the'machine-to'a stop at will before it is stopped automatically as above described, to e'nable'him to adjust the upper 'materials beforethey are completely wiped into lasted position ifhe should observe such an adjustment-to be necessary. For this pur pose there *is'pivotallylmounted on the bellcrank lever 408 a rod 448 which extends'downwardly through a block 450-pivoted on one side of the'treadle 418, nuts 452 being mounted on the rod below=the block 450. Initially there is a considerable space between the-block and the nuts to provide 'for-lost-motionsuch as to render the treadle effective to start the machine as described. If at any time the operator should desire to stop the machine, he simply depresses the treadle 'farthcnso that the block 450 engages one ofthe nuts 452 and thus moves the rod 448 downwardly, thereby operating the bell-cranlvlever 408 to disengage the clutch member 394 from the clutch face 392;"It will be evident 'tlia'twhen'the operator releases thetreadle the machinew'ill immediatelyv resume its operation and will thereafter come to a stop automatica'llyat the shoe. The wipers are thereafter further.

the point predetermined by the automatic controlling means hereinbefore described.

In the o eration of the machine,- briefly summarize the operator first depresses the treadle'fll and thereby swingsthe side clamp arms 62 apart and then swings these arms and the end clamp member 32 rearwardly. He then mounts a last and shoe on the last pin 24 with the shoe materials wrong side out, and if necessary tips the shoe and moves it bodily sidewise to locate it approximately in a central position on the shoe'support with the sole in such position that it will be substantially parallel to the plane of the wipers When the shoe is carried to operating position. Thereafter the operator releases the treadle 7 1, whereupon the yoke member 34 is swung forwardly by the spring 4 1 to press the member 32 against the rear end faceof the shoe and'the side clamp arms 62 arethen swung toward the shoe by the spring 72 to cause the members 64'to clamp theshoe and position it centrally on the support. As illustrated, a portion of the lining of the shoe which is outside of the counter is turned back, so that the clamp members, and later the wipers, directly engage the counter.

After'the shoe hasjbeen mounted onqthe shoe support and clamped and positioned as above described,the machine is started by depression of the treadle 418. The shoe support and the shoe clamping means are then swung rearwardlyby the bell-crank lever 1&6 until the roll 40 engages the plate 42,'and at the same time the shoe support is Ymoved upwardly by the lever 162, the upward movement continuing after the rearward movement has ceased, until the shoe is forced against the gage member'30 under the heavy pressure of the spring 160. The shoe support rod 22 is then looked against downward move ment by the pawls 174. Thereafter the wipers are moved forwardly toward the shoe and are closed around the heel end. of the shoe below the edge of the shoe bottom, as illustrated in Fig.11, and are pressed yieldingly in contact with the counter through com pression of the spring 238 of'the wiper-advancing mechanism and the springs 278 of the wiper-closing mechanism. In this movement of the wipers the pawls 153 are rendered effect-ive to lock the shoe support against forward movement. While the wipers are thus pressed yieldingly against the shoe the wiper carrier 208 is swung upwardly by the bellcrank lever 332 to impart to the 'wipersan upwiping movement while pressing the counter inwardly all around the heel end of advanced and closed to wipe the upper materials including the counter; into the angle between the shoulder andthe margin of the sole while being pressed yieldingly downward by the light spring 364: (Fig. 4), and at the end of their advancing and closing movements they are forced positively against the upper materials to assist in forming a good crease therein, as hereinbefore described. Substantially at the end of the wiper-advanc- ,7

I ing. and closin movements the heavy spring chinehasbeen again started; After the operator has depressedthe treadle 418 to start the machine the second time, the'wipers are lifted and retracted from they shoe and the other parts are returned to their starting positions, the shoe support being first lowered and then swung forwardly from under the gage member 30. If the operator has applied the binder wire around the heel endof the shoe in the manner described, he may then fastenit to a tack at the opposite side of the shoe. As previously explained, however, the use'of such abinder wire will under most conditions be found unnecesssa r5. Before removing the shoe from the shoe sup port the operator depresses the treadle 74, whereby the side clamp arms 62 are first swung away from the shoe and are then swung rearwardly together with the end clamp member 32 to release the shoe.

As hereinbefore suggested, the invention 7 in various novel aspects is not limited to ma chines for operatingjon turn shoes, and the term sole is accordingly used in the claims in a generic sense to'include not only the sole of a turn'shoe,but also that part which in shoes of other types may be the insole.

Novel features of the starting and stopping mechanism herein disclosed are claimed in a divisional application, Serlal No. 561,198
