This invention relates to machines for iaping shoe uppers, and is herein illustratd as embodied in a machine constructed to operate upon a previously untensioned upper 0 ension it over a last and also to last the oe-end portion or" the shoe.

t will be recoged. however, that in some of its novel ascts the invention is not limited to an ornization of that particular character. In the manufacture of various kinds of shoes. including welt shoes, it is the common practice to subject the upper to a pullingover operation, wherebv it is tensioned or stretched lengthwise of the last and also lghtwise thereof at the forepart and is ihaped in general conformity to the contour the torepart of the last, and thereafter to last the toe of the shoe in a different mac ine, usually after the sides have been lasted etween the toe and heelend portions. It has, however, been proposed to tension the upper over the last and to last the toe in the same machine. one type of machine for that purpose being disclosed. for example, in Letters Patent lio. 1.702.397, granted on Februarv 19. 1929 upon an application of N. C. Baxter. Among the advantages of this procedure are the avoidance of such loss of tension in the upper as may result from the Lrawal of one or more of the pulling over tacks preparatory to the toe-lasting operation and or difficulties due to the necessity of reshaping, more or less. in this operation portions of the upper shaped in substantial conformity to the contour of the last and insole in the pulling-over operation. Furthermore. by thus tensioning the upper and lasting the toe before lasting the sides the shoe may be conveniently prepared for presentation to a combined side-lasting and weltins; machine of the tvpe disclosed in my copendinp; application Serial No. 325,839. filed on December 13. 1928. it it is desired to make use of such a machine.

i; :1 object of the present invention. among others. is to provide an improved machine irtecl to operate in the above-menmanner, the invention being herein as applied to a machine of the ral type as disclosed in the abovementioned Letters Patent No. 1,702,397. In one aspect, the invention provides a novel organization of means for shaping an upper over a last by relative movement of the upper and the last. The machine herein shown is so constructed that the marginal portion of the upper is clamped at its toe end before the upper is mounted on a last, after which a last, supported at first by the operator, is moved by the machine toward the upper, the arrangement being such as to enable the operator to apply the heel end of the upper about the heel end of the last prior to such movement of the last. In order to tension the upper longitudinally, the last in the construction disclosed is moved in a lengthwise direction as well as in the direction of its height to force it into the upper, its lengthwise movement being initiated after the beginningoi its heightwise movement.

The lengthwise movement of the last, as illustrated, is effected through contact With the bottom face of an insole on the last, one form of construction disclosed, moreover, including a member arranged to act on the toeend face of the last to assist in this movement. A further feature comprises novel means whereby lengthwise movement of the last is effected by relative movement of parts of a device that is moved heightwise of the last to force it into the upper, such relative movement, in one form of construction illustrated, resulting from resistance of a yieldable shoe support to the heightwise movement of the last, and, in another form, being ef fected by means that is not dependent upon such resistance.

In another aspect, the invention provides novel means for controlling the marginal portion of the upper in the upper-shaping operation. The machine herein shown comprises toe-embracing Wipers for Wiping the marginal portion of the toe end of the upper into lasted relation. to an insole on the last, and means for clamping the marginal portion of the toe end of the upper on the Wipers to assist in tensioning and controlling the upper; and for purposes of this invention there are provided additional members for clamping the upper upon the wipers at the grippers providedjlfor gripping and control'-' rear of its toe-end portion prior to the inward I wiping movement of the wipers. V In the construction shown the wipers are formed and arranged to wipe the upper inwardly Over the insole along the sides of the shoe substantially as far rearwardly; as the ball of the shoe, and the additional clamping members .are arranged to control the upper in locations nearthe ball of th' e; shoe" andat the rear of ling the margin of the upper at or: near the tip seam. In accordance with further novel characteristics; of the illustrative construction, the additional clamp members 'arecarried by the means that is moved heightwise of the last to force the last into the upper,

- and are so controlled that they are permitted to move inwardly towardthe shoe with the wipers during a portion of the movement of the wipers and are then stopped while the wipers continue their movement. Initially,

ption of thelast. v

moreover, these members are arrangedto occupy positions near the opposite sides of a last presented to the machine by the operator to assist in determining Theinvention also provides anovel organization including means for pressing portions of the upper into conformity to the contour of the last, with the object not onlyof assisting in the proper lasting of thetoe portion of the upper, but also of positioningport'ions of the upper at the rearof the toe in approximately the right relation to the last where they tend to remain after the lasting of the toe',soas to facilitate the proper side-lasting of the shoe without disturbing the previously lasted toe. The construction shown comprises a shoe support which presses the upper into conformity to the contour of the last at the top of-the forepart at therear of the toe,

and fluid-pressure means that conforms the upper to the sides of the last at the rearof this shoe support. As illustrated-this fluidpressure meansfcomprises pneumatic pads which are spaced from eachother and are arranged to press the upper to the sides of the last at the waist portionandsubstantially the shoe. I

The invention further 1 provides novel means for determining the proper position of the upper relatively to the wipers. In one form illustrated this means comprises fingers that are movable into or outiof positions substantially contiguous to the upper on the op- "as far rearwardly as the heel-end portion of posite side thereof from thewipers, when the margin'of the upper is outspread upon the -wipers, for. gaging by reference to the tip 'seam theipositionofthe upper relatively to the wipers,these fingers being arranged to be controlled'by the operator and being adjustable for uppers of different sizes. In another form the gaglng means comprlses a dev ce the proper posimounted for movement intoor out of a posi tion'close to the upper on the same side thereof as the wipers, this means, as illustrated, comprising a plate having an edge portion 1 against which the operator is enabled to press the upper to determine by reference to the tip ;claims., .1

Since the invention, as above staned, is herein illustrated as applied to a machine or the same general type as disclosed in the above-mentioned Letters Patent No. 1,702,397, only such parts of the general organization of the machine as it is necessary to refer to for an understanding of the inven tion are herein shown and will be descrioe in detail. It will be understood that the i llustrative macnine comprises two sets of operating instrumentalities for operating re spectively upon right shoes and left shoes, the difierent sets performing their op rations alternately. The drawings, however, show portions of only one of these of instrumentalities, since the different sets are similar to each other in construction an rangement.

The machine is provided with a table 22 mounted on the top of a suitable frame, and each of the sets of operating instrumentalities includes an arm 24 supported on this table, the arm being mounted at its rear end on a horizontal pivot, not shown in Fig. 1 but indicated at 26 in Fig. 17, for downward swinging movementin a vertical plane to force a last into an upper controlled hereinafter described. It will be understood that this arm is swung downwardly and upwardly by power-operated cam mechanism such as disclosed in the above-mentioned Letters Patent. On the front end of the arm 24 there is a horizontal pivot 28 upon which, for one of the objects of this invention, as more particularly hereinafter explained, there is mounted a block 80. The extent to which this block may turn about the pivot 28 in a counterclockwise direct-ion is limited by contact of a lug 32 at the rear end of the block with an adjustable hook 34 secured to the arm 24, spring 36 being provided in a bore in the arm 24 to swing the. block in this direction. Movement of the block in the opposite direction is limited by means of stop faces, not shown in detail, on the block and the arm. A threaded rod 88 extending upwardly through the block in front of tile pivot 28 carries at its lower end a toe plate 40 having a roughened lower face and shaped to fit within the rib extending around the toe end of a welt shoe insole, the edges ofthe plate being beveled to permit it to abut snugly against the inner side of the rib. A hand nut 42 threaded on the upper end of the rod 38 may be turned to adjust the plate 40 upwardly .or downwardly. Mounted in a slot in the front end of the block 80 on a horizontal pivot 44 is a three-armed bracket 46 provided with forwardly, rearwardly and downwardly extending arms. A stem 48 is adjustably secured to the front face of the downwardly extending arm of the bracket 46 by means of clamping screws 50 extending throu h slots in the stem, and at its lower end tne stem is so formed as to provide a presser foot 52 the lower face of which is roughened, as by knurling. The presser foot 52 may be so positioned that when the toe plate 40 is seated flat upon the toe-end portion of an insole on a last within the rib of the insole, the presser foot engages the insole substantially at the front end portion of the shank, as illustrated in Fig. 6. The presser foot 52 is also so positioned that when an insole is in proper engagement with the toe plate 40, the presser foot is substantially in engagement with the inner face of the insole rib at one side of the shoe bottom, as shown in Fig. 7. In order to adjust the stem 48, and accordingly thepresser foot 52, relatively to the plate 40 in directions heightwise of the last, there is provided a screw 54 extending through a threaded hole in the forwardly eX- tending arm of the bracket 46, this screw hava knurled head which extends into a transverse groove formed in the stem 48. After the clamping screws 50 have been loosened the screw 54 can be turned to raise or lower the stem 48 in accordance with the slope of the shank portion of the bottom of a shoe to be operated upon. The presser foot 52- is adjustable toward or from the toe plate 40 in directions lengthwise of the shoe by means of ascrew 56 threaded in the rearwardly extending arm of the bracket 46 and bearing at its lower end upon the block 30. The toe plate 40 and the presser foot 52 are so arranged that by downward movement of the arm 24 they depress a last within an upper positioned and controlled as hereinafter described and force the last and upper downwardly upon shoe-supporting members. These members comprise a forepart support, indicated generally at 58, and a cradle 60. The foreparrsupport 58 is mounted on a holder 62 which, as shown in Fig. 2, is swiveled, by means of a curved lower face, for movement about a horizontal axis extending lengthwise of the last at about the level of the longitudinal median line of the upper surface of the forepart support to acconnnodate differently shaped lasts. By means of a screw 63 the support 58 may be adj nsted relatively to the holder 62 in directions lengthwise of the last. The support 58 includes two

members

64 and 66 both of which are formed of comparatively hard but still resilient. material, such a stilt rubber.

The member 64 is arranged tosupportthe wardly of the. tip line nd at either Side of the longitudinal medianline of the last, as

The cradle 60,' whichvis secured toa fixed sleeve 69 in which the stem '67 is mounted. and accordingly does notmove vertically with the forepart support 58, comprises two wings on the last; The pads'TOYare arranged to spaced somewhat apart and each lined with an inflatable lpad70, these pads beinginfiated automatically at' a certain time inthe operation of the machinetopress against the upper engage the portionsof the sides ofthe u per whichllie on either side of the-last, .and in the construction shown each: covers an area extending from immediately at the rear of the forepart support member 66to a location attheside of the heel-end portion of the shoe, as shown in Fig. 8. The pads 70, as shown inFig. 3', are arranged to provide a wedge-shaped opening between themv within which. the lastiand upper are received, the

pads being spaced from each other far .y enough to avoidj applying any substantial pressure to portions of theupper at the top of the last which'the lacinglinormally occupies if theshoe is a laced shoe."

. LFor lasting the forepart of the shoe; the machine further includeswipers 7 2 mounted in carriers 74 v(Fig.3) haying cam slots 76 i and 78 cooperating with rolls .80 and /82 to ctfect the closing movements of the wipers laterally of theshoe, the carriers 74 being advanced and retracted by a cross-head84 connected to the carriers bylinks-86.

By reference to Figs. 1 and 21it. willi{be seen that a yoke. .92, arranged to extend laterally of theshoe rise: and fall in the slot; and is controlled tendingthroughthe yoke and fixed inthe pbfy a spring,94whioh-surroundsarod965'ex- V yoke at the bott'om of theslot Mounted on pivot pins at theaoppositefends of the oke 92 are two depending arms 102.

Nuts 108 on therod 104 at the inner'sidesof the arms 102 determine the distance between the arms; a spring 110 beingprovided to hold the arms against the nuts." The rod 104 has onits opposite endsri'ghtjand left-threads for the nuts 108,-so that by turningit with a screw driver inserted in a slot'inone or the other of its ends the arms 102 may be made to ap-' proach or separate from each other in ac,- cordance withthe width of the shoe being operatedffupon'. Near theirlower ends the.-

The rear endsof the members 112 are turned down to provide pressers 114 having rough-1 ened lower faces forengagingtheupper materials and pressing them upon the upper faces of the wipers 72 The pressers-l14 are arranged to cooperate; asmore particularly hereinafter described, with

the'imembers

40 and 52 in positioning a last correctly in the machine, and for this purpose they may be adjusted by the rod 104 to stand in comparatively close relation to the sides of the last when the last is presented to the machine. The members 112 are adjustable along their guideways in accordance with the size of the shoe bein operated upon and are held in adjusted positions by clamping screws 116.

As above described, the yoke 92 which carries thepressers 11 1 is controlled by the spring 94 which tends to maintain it in its lowest position in tne slot in the block 30. in order to lif the Dressers 114 from the wipers earlier than they otherwise would be lifted in the return of the parts of the machine to their starting positions near the end of the cycle of operations, additional mechanism is provided. This comprises a latch 118 mounted on a pivot 120 on the front portion of the block 30 and cont-rolled by a light spring 121 which tends to lift it, the upper end of this spring being connected to a pin 122 on the block 80. hen the parts of the machine are in their starting positions the upward movement of the latch 118 is limited by contact with a fixed stop 12% on the frame of the machine, as shown in Figs. 1 and 2, and when the arm 2% is lowered from the position in which it is shown in these figures the upward movement of the latch is limited by contact with a pin 126 secured to the yoke 92. The latch 118 is provided on its upper face with a notch 128 (Fig. 2). It will be understood that when the arm 24 has completed a portion of its downward movementthe yoke 92 comes to a stop by reason of contact of the pressers 11% with the upper, whereupon the latch 118 continues its downward movement with the arm until it is carried below the pin 126, the spring then acting to swing that portion of the latch where the notch 128 is located into a position under the pin. With the parts in these positions, upward movement of the arm 24: and the block 80 at the end of the cycle of operations causes the latch to lift the yoke 98 through the pin 126 and thus to lift the pressers 114: at the beginning of such upward movement, so as to avoid possibility of objectionable interference with other parts of th machine, As the arm nears the end of its upward movement the stop 12% engages the tail end of the latch 118 and withdraws the latch from under the pin 126, so that the spring 9 1 may return the yoke 92 to the lower end of the slot in which it is mounted.

It is desirable that when the wipers 72 are moving inwardly the pressers 11 1 be permitted to approach each other to some extent, in order that they may approach more closely to the sides of the lastif the width of the last diminishes near its bottom edge, or in order that they may move somewhat inwardly over the feather of the insole with the wipers. To

after downward movement of the arms has been stopped by engagement of the pressers 11 1 with the work, the nuts 108 are carried into positions opposite the cam faces 130, the wipers by that time having started to move inwardly toward the shoe, and the pressers 11 1 are then drawn toward each other, by the spring 110 by the action of the upper thereon, as far as permitted by engagement of the nuts 108 with the cam faces. The fact that the pressers 114 are thus arranged to move toward the shoe with the wipers during the early part of the inward wiping movement of the wipers permits the upper materials to be wrapped well around the shoe in locations opposite the pressers without being subjected to any substantial increased tension by the wipers until toward the end of the operative movement of the latter when, the pressers having ceased their inward movements, the upper is drawn from beneath them by further movement of the wipers. It has been found that by thus permitting the pressers to move with the wipers during the initial movement the latter, danger of tearing the lining by sudden action of the wipers thereon is avoided. Among other advantages, the pressers, by pressing on the lining, act to clear the latter in an effective manner from folds or wrinkles.

in the use of the machine as thus far described in the manufacture, for example, of a welt shoe, a loose upper, including the lining, the counter, and a toe stiffener (for example, a heat-softened thermoplastic stiffener), is placed in the machine upside down with the margin of the forepart of the upper resting on the wipers 72 and extending beneath the raised clamp members 88 and between the jaws of the open grippers 90. The relation of the upper to the operating instrun'ientalities at this time is indicated by Figs 1 and 5. Care is taken to see that the tip line (represented at 132 in 5) lies approximately over and parallel with the meeting line of the

shoe support members

64 and 66. When the upper is thus presented its rear portion will sag downwardly, as indicated in Fig. 4, until its further downward movement is resisted either by stiffness of the upper or by the pads 70. Having thus presented the upper, the operator starts the power operation of the machine by a treadle, as dis closed in the above-mentioned Letters Patent No. 1,702,597, whereupon the arm 24; is swung downwardly by its operating mechanism, the arm continuing its downward movement until the parts of the machine are substantially in the positions illustrated in Figs. 6 and 7. At this stage the machine is brought automatically to a stop by; 'a suitable modification" 'ofithe controlling mechanism. It will be observed that at this time the-clamp members 88have been lowered to clamp the upperup-zon'the wipers and the jaws of .the grippers -90 have been closed to grip the upper.

. The operator ,thentakes a last-having a i ribbed insoletastened thereon and presents the last and insole in a position in which the .10

toe .plate 40. is seated snuglyagainst the inner face of the insolerib :at the toe end, at: V the same timemoving the heelend'ofthelast,laterally-untilthe presser foot 52 is in substantial engagement with the inner face ofthe insole rib at the inner side of the shoe bottom, as indicated in F 7 The operator also observes that the last is positioned I with its opposite sides at substantially equal distances from the presse'rs 114;,which will have been previouslyadjusted as close togetheras desiredto cause the last, as it is in'sertg' ed in themachine, to assume anapproximate- 1y correct lateral position.

It will be noted by reference to Fig. 6;that

A. Holn'igren. During this i or drives a number of tacks,

. at each side of the of a hand tucker to er in positi notches 1 11 the wipers to permit ti. o of the three tacks at each. side oned accurately. VVhc-n the ma- 1 operation the arm rises, e mock with it. the pres. s lifted by the latch 118 which has i y .lipped beneath the pin 126. At

also the air is automatically re- 1 m the pads 70. As the result of iovement of the parts toward starting ".ze shoe is released and can be ZC from the machine. It has been found preferable in the return 7 of the parts to starting positions to cause the 65 block to rise with the arm 24 as if it were secured rigidly to the arm, in order to avoid the possibility of interference between parts carried by the block and other parts of the machine. To thisend there is pivoted at 138 (Fig. 1) on the arm 24 a latch member 140 which is hooked at its upper end and has an arm 142 carrying a pin 144 which extends into a slot in a link 146 pivoted at 148 to a lug on the table 22. A spring 150 connected to the arm 142 tends to turn the latch 140 in a counterclockwise direction. When the arm 24 is lowered and the relative turning movement of the arm and the block 30 about the pivot 28 takes place in the latter portion of the downward movement of the arm, as hereinbefore described, the hooked upper end of the latch 140 is moved by the spring 150 to a position over a shoulder (not shown) on the block 30, the pin 144 meantime traveling down the slot in the link 146, so that when the arm 24 is lifted the latch causes the block to rise with the arm without turning about the pivot 28. The block 30 is thus held by the latch until the arm 24 approaches the end of its upward movement, at which time the pin 144 arrives at the upper end of the slot in the link 146, and then during further upward movement of the arm the latch 140 is withdrawn from the shoulder on the block 30, permitting the latter to be swung by the spring 36 to the position determined by the hook 34.

The machine shown is also provided with means for trimming the margin of the upper around the toe after it has been wiped inwardly by the wipers. This trimming means is constructed and operated substantially as in the machine shown in Letters Patent No. 1,702,397, and comprises a knife 152 which is carried by a sleeve 154 surrounding the rod 88 and lies approximately in contact with the upper face of the toe plate 40. This knife is operated through pinions 156 and a rack and pinion device 158, the rack being reciprocated by a link 160 which is operated as disclosed in the last-mentioned Letters Patent. The knife 152 moves around the toe end of the shoe and shears off against the upper faces of the wipers the excess of upper material and any excess height of the insole rib. A rod 162 extending downwardly through the block 30 has a nut 163 on its upper end and is connected at its lower end to a lever 164 which is pivoted at 165 on an extension of the block 30 and projects at one end into a groove in the sleeve 154. A spring 166 tends to move the rod 162 downwardly, the downward movement being limited by engagement of the nut 163 with the block 30. In this manner the position of the knife 152 in relation to the plate is determined. The

nut 163 may be adjusted to position the knife lVhen the shoe is removed from the machine it may next be takento a bench where it is spindled? and a binder} wire is applied around'thetoe' andfanchore'd at its ends to two. of the tacksprleviouslyjdriven, in order: to h-old thi'siportion of the. uppermo're-se' curely in place.

The fingers 168 may be swung upwardly from the position illustrated in Fig. to permit a shoeupper to be placed upon. the Wipers "beneath the fingers. For thispurpose the fingers are connected at their outerends to rods'172 the-lower ends i of which extend through trunnions mounted inthe ,outer endslof leversl-f 1. .Springsl76 hearing at their, lower ends on the trunnions and at their upper endsonfcollar'szon the rods 172 provide a yielding connection betweenjthe levers 174 andthe rods.

The 'V-innerends of' the levers 1741 are arranged to overlap each other, as shown in Fig. 11, and one of them carriesapin 184 which projectsinto a slot in theend' of the other lever. One of the levers is connected toa rod 186 which may be connected at its lower end, by means not herein shown, to the starting treadle of the machine The connections may be such that initial downward movement of the treadle, by pulling on the rod 186, causes'the fingers 168 to be swung downwardly from ajraised-inoperative positioninto contactwith the'upper materials o'utspread-on the wipers. lithe upper materials are in proper relation "to the fingers,

Itwill be understood that the fingers 168 are i 7 s0 mountedon the pins 170 astom'ove with thelatter indirections lengthwise otthe upper, and that the connections between; the.

fingers and the levers 17 4' are suchas to per- 7 mit this movement. The upper facescf the V bosses in which the pins 17 0 are mounted are provided with grad'uations, :as shownlin Fig.

Instead of the work positioning' or gaging means shown in Figs.'10'-and 11,1the forepart shoe support may be modified, as indicated at 190 in.Figs..12 and113, tolpermit theuse of 'gagin'g'means of a different character. The support 5190 comprisesapad similarin shape to the pad66, butmade of comparatively hard felt nstead of rubber. Moreover, the base 192 on which this padis fixed is mounted on the top of a modified stem or .post 194 in such manner that it cannot rock laterally like the

supports

64 and 66, but can be adjusted about the axis of a stud 196. In

,front of the support190 is a metal plate 198 shaped in plan somewhat like the toe'end of a shoe and having a plane upper face. The

rear edge of this plate is straight and is adapted to lieparallel to and fairly close to the stra ght forward edgeof the pad 190.

A short rib 200 is'provided on the rear edge of the plate198 at each-side thereofand proi MP P lymm s shown'in Fig. 12; 3

Each rib is undercut to provide a comparatively sharp forward edge along its top. The plate 198 is secured to the upper end of a vertically movable stem 202 which is mounted in a groove in the post 194. The stem has a forwardly extending lower end 294 which is mounted in a ecess 206 in the post 194. A vertical rod 208 is screwed into "the lower end of the stem 202 and extends downwardly through av tube 210 which is screwed into the lower end of the post 194. The rod 268 extends below the tube 210, as shown 14, and has a ball-shaped lower end. i la 1. 212 is arranged to engage the lower end of the rod 208 and is mounted to rock about a pivot 214 in a bracket 216 which is clamped to the tube 210. The lever 212 is connected by a chain 218 to a small treadle 226 which is mounted the base of the machine close to the starting treadle 222, so that it can be depressed to raise the plate 198 to the s tion shown in Fig. 12 without depressin the starting treadle.

hen the machine is provided with gagmeans such as above described, the plate 198 will initially occupy a position well below that in which it is shown in Fig. 12, with the forwardly extending lower end 204 of the stem 202- resting on the post 194 the lower end of the recess 206, the parts being held in this relation by a spring 224 (Fig. 14) connected to the lower end of the rod 208. When the operator wishes to present the shoe upper to the machine, he first depresses the treadle 220 and thereby lifts the plate 198 until the upper face of the plate is approximately at the same level as the wipers 72, so that the ribs 200 are in positions to engage the lower face of the upper outspread on the wipers. While holding the plate at this hei ht the operator places the margin of the forepart of the upper on the wipers and between the jaws of the grippers 90, pressing portions of the upper downward slightly on the sharp forward edges of the ribs 200 and adjusting it until he can feel that the ends of the tip seam are over the front edges of the ribs. The operator next releases the treadle 220, thus permitting the plate 198 to drop to its lower position out of contact with the upper, and then depresses the starting treadle 222. The plate 198 is secured to a head on the upper end of Lee stein 292 by a stud 226 about which it can be turned slightly to bring the ribs 200 into proper position in operating on uppers of suoes of different styles.

In the modified construction above described more convenient means than illus trated in Fig. 1 is provided for adjusting the forepart. support in directions lengthwise of the shoe. To this end the sleeve which supports the cradle 60, shown in Fig. 12 at 228, has a stem 230 which is movable forwardly and rearwardly in a bearing in a lug 232 secured to the head of the machine. The outer end of the stem is forked to receive the end of a flat horizontal lever 234 connected to it by a vertical pin 236. The opposite end of the lever is mounted on a vertical pivot 238 on the frame of the machine. Between its ends the lever 234 has pivoted to it a trunnion 240 in which the rear end of a rod 242 is threaded. At its forward end this rod extends through a bearing 244 in the frame of the machine and has shoulders which abut against opposite ends of this hearing to prevent lengthwise movement of the rod. At its front end the rod 242 is provided with a knurled head 246 by which it may be turned, and by such turning movement the lever 234 is swung about its pivot 238 forwardly or rearwardly to vary the position l ngthwise of the shoe of the

members

190 and 192. Any suitable indicating means may beassociated with the head 246 to assist in making proper adjustments.

In Figs. 15 and 16' is shown a portion of mechanism which may be utilized for quickly and conveniently adjusting toward and from each other the grippers which grip and control the margin of the upper near the ends of the tip seam to position them properly for operating on uppers of shoes of different sizes, only one of the grippers being shown in these figures. For this purpose each gripper bar 248 is rigidly connected at its upper end to a forked lever 250 which is mounted on a horizontal pivot 252 on the head of the machine close to the upper end of the gripper bar. Each lever 250 is connected at its outer end by a link 254 and an arm 256 to a rock shaft 258 to which a depending lever 260 is secured, the rock shaft extending in directions lengthwise of a shoe in the machine and being mounted in fixed bearings on the head of the machine. Each lever 260 is connected at its lower end by a pin 262 to a block 264 which is movable in directions widthwise of the shoe. The two blocks 264 connected to the levers 260 at the opposite sides of the machine are associated with a rod 266 which extends through them and is provided on its opposite ends respectively with right and left hand threads, the threaded portions extending through enlarged holes in the blocks and engaging threads formed in non-rotatable blocks 268 positioned at the outer sides of the blocks 264. On one end of the rod 266 is a knurled head 270 by which the rod can be turned, and a lug 272, adj ustably fixed to the machine frame, extends into a groove in the hub of the head 270 to hold this head and the rod 266' against lengthwise movement. A sleeve 274 which is adjustable in length is loosely mounted on the rod 266 and provides an abutment for the inner ends of two similar springs 276, the outer ends of which bear on the blocks 264. These springs serve to hold the blocks 264 normally in engagement with the blocks 268, but are yieldable to permit with the blocks 268, thisiresults inladjustment of the. grippers toward or from" each other; .A link 27 8 connects one of the blocks grippers to be swung toward each? other by the pull of the upperthereon' in the manner hereinbefore explained, sTurni ng move 7 V mentof the rod 266 causes the blocks 268 to move lengthwiseof the rod toward or from each other, and since the blocks 264' move,

As there indicated, the'block 30 is'provided with an upstanding lug 292*s'ecured on its upper' surface farther rearwardly of the machine than thepivot-28,-the upper end of the lugbeing f forked and provided with a pin 29 ixextending transversely across the opening in its forked end A rod 296 is arranged with-its j frontend portion 'in-this opening-and is pro- 8 vided with a slot-298 through which the pin 294 extends, the length ofthe slot being such as to j afford provision for asubstantial amount of relative movement between the rod and the "pin in directions lengthwise of the rod. The rear end of the rod 296 extends through a, 'block' 300 which is pivotally mounted on a transverse rod 302 secured in uprights 304 fixed on the frame of themaehinenear therear end of the latter and close tothepivot26 about which the arm 2 L swings.

The rear end ofthe rod 29 6.is threaded and carries a wing nut 306 between which and the rear end' of the block 300 is mounted a compression spring 308 which tends to pull the rod 296 rearwardly, such rearward movement being limited by contact of ainut 310 onthe rod with the front end or the block 300.1 With the parts thus constructed and arranged,-the

I-initial downward movement of the arm 24 to Y bring the toe plate and the presser foot 52 to-the positions indicated-in Fig: 6 causes the rod 296to swing-downwardly about the rod 302 and'the pinf294 to travel towardthe front scribed.

"Whentheop erator starts the machinethe second time, aft- 1 er presenting thelastidposition to be operated upon, the pin 294 arrivesat the frontend of the slot29 8 before theshoe isforced with i any considerable pressure against the shoe support 66, whereupon the rod 296, acts through? the pin 294 tocause relative swingingfmov'ement-between the block 30 andthe arm 24: about the pivot 28 as the arm 24 continues its downward movement. According ly the relativemovement of the block and the arm is effected by-the -mechanism described in predetermined time relation to the movement of the arm, instead of in response to, resistance. to downward movement of the lasti I It will be understood that the" spring 808 is yieldable to permit forward movement of the rod 296 in case the block 30 has been turned tothe limit ofits'movement about the pivot 28 before the arm 24e'completes its downward movement. The rod 296 is arranged to act as described before the shoe is forced with any substantial pressure against the forepa'rt support 66,1the toe end of the last being swept past ,the'wipers into engagement with the'upper in a curve direced-both downwardly andrearwardlv. When the last has "reached the position indicated in Fig. 8 the pa'ds'TO' are inflated and the lasting Opera'- y (if) tion. conti'nuesinthe manner previously deoperatorin holding the work up against these members. 7 Accordingly the trimming {knif 152is removed'from the machine,and alever, 311,-wh1'oh takes the place of the le'vor,

16d (Fig. 1') is mounted onthe pivot lgand is-provided withaydownturned lug 312 ar- "rangedto abut against the toe-end face of thelast when the last is presented to the machine and thus to act as agage to assist in determining the proper position of the last.

The lug 312 remains in contact with the end of'the last as the block 30 beginsto' turn about its pivot 28 and therefore serves posi- 'tively-to push the last in' a rearward direc tion in cooperation with the insoleeengaging members lO and 52, obviating any tendencyj for these. members to slip on the bottom fa eQOf; the insole. 'The lug 312 is so positioned" that it is over the upper faces'of the wipers 72 during the final part of-the downward movement'of the arm 24, with'its front face in vertical alinement" with the "front edges. of the wipers, its downward movement being-stopped by the wipers" Downward movement of the block 30 relatively to the lug 312, as required to bring the last into proper position for the overwiping operation, is permitted by reason of the fact that the lever 311 is pivoted at 165 as described, the lever being controlled by a rod 162 in the same manner as the corr sponding parts previously described for controlling the knife 152-, the spring 166 shown in Fig. 1 having, however, been removed.

Means that may be quickly and conveniently used for adjusting the arm 24 relatively to its operating mechanism so as to vary the height of the toe plate 40 and the presser foot 52 at the limit of the downwarc movement of the arm and thus to position the insole in proper relation to the plane of the wipers as the thickness of the upper materials varies in operating on different kinds of shoes, is shown in Fig. 18. In that figure 31% represents one of a pair of links coupled to the arm 2-l at its opposite sides respectively to move it downwardly. The upper ends of these links are provided with bearings in which lit collars 316 which are coupled together by a rod 318 arranged eccentrica-lly of the collar this rod extending through a bearing in the arm 2 1 and ha ing a handle 320 secured on one end thereof. It will be understood that by turning this handle the eccentric collars 316 are rotated to adjust the arm 24: as desired. To hold the collars in any one of a number of different adjusted positions there are provided a pluralit-y of holes 322 in the arm 24, and the handle 320 carries a spring-pressed plunger 324 adapted to enter any one of the holes or to be withdrawn therefrom.
