The parts of the shoe to be operated; onfare assembled on a'la'st which is carried by a ]ack 5, and the sole, after vbeing''placed in proper position Aonv the bottom ofthe la"st,vis` acted upon by a roll L'fcarried by an arm 3. The jack is reciproeated and is also rotated at proper times to cause the roll to act 'progressively along thesur'face of the solegand about'tlhe edge whilethe roll is rapidly vibrated and 4automatically manipulated to secure the proper rolling actionon different parts of the sole.l `At the beginning of the rolling operation the roll is engaged with'the center'of the heel'at the breast. riihe roll first passes over the heelto the' back of the shoe.

opposite direction, and then rolls to the rear of theheel. The roll is then shifted laterally to the center of the heel and rolls toward the toe, drops" from the heel to the shank, and rolls the length ofthe forepart, as shown at b. As the roll passes olf the toe it drops downward to alimited extent so f that it turns down the beveled edge of the sole at this point. yThe downward move ment offthe roll at this point is only sufficient to insure proper action .upon the extreme point of the toe, and the roll-is held. in such a position that it will lift itself up on the sole when it travels in the opposite direction, without injury to the shoe. While olf the toe the roll is shifted laterally an its Ylateral inclination changed to conform to the lateral curvature of the sole. rThe roll now operates over` the sole as indicated at c to the heel breast, Where it is given a still greater lateral inclination and again shifted laterally. As the roll passes from the shank to the ball, the lateral inclination is somewhat reduced to correspond to the variation in the lateral curvature of the sole. lThe roll now operates toward and rolls oil' the end of the toe. It is then shifted laterally to the other side of the medial line, and is manipulated to roll the sole on this side in a similar manner. Each time the roll approaches the breast of theheel during the rolling of the vforepart and shank the vibration vof the roll causes it to hammer the breast. As the roll approaches the toe for the last time, as indicated at d, its travel is arrested before it passes olf the end of the toe, and it is tiped'laterally -to an extreme angular position Which-may be nearly vertical. The jack is rotated through 180, which causes the roll to travel about the 'toe and to turn over th'e beveled edge of the sole and bring it into contact with the upper. The jack is then moved longitudinally to cause the roll to travel along the edge of the shoe while held at an angle, as indicated at e, Fig. 22, so that it turns over the edge of the sole. of the heel its vibration is stopped and the roll is turned at an angle to the longitudinal center line ofthe shoe, as indicated at f, Fig. 22, and is lifted to the tread surface of the heel, so that it lturns over the sole edge along the sides of the heel breast. When the roll reaches the tread of the heel it is again vibrated, and at the same time it is 'turned to a right angle to the center line of the shoe.

The longitudinal movement of the jack is then continued until the roll reaches the curved end of the heel, at which When the roll reaches the breast.

time the jack is rotated 180j tocause the roll to travel about the heel end of the shoe, as indicated at g. The ,other edge of the shoe is rolled in the same manner, the roll passing along 'the side of the. heel, down the heel breast, and nearlyv to; the toe, so that it slightly exceeds a complete circuit of the sole. Here the roll is returned to 'a' hori zontal position in 'the center f the' s hoe, which passes beneath the roll until it reaches the breast. The roll is lifted up the breast, down again, and up, and then lifted above the shoe, which completes its cycle of-'operation. The relative movements between the jack and roll described are those which it is shank it is preferred to hold the roll at an i inclination transverselyof its directionof travel, and to also give the roll an angular vibrationV as well as a back and -forth vibration in the direction of'travel. It has been found that this adds to the certainty with which the edge is rolled over' and attached: to the upper.

The devices for supporting the roll so that it may be automatically manipulated as described are as followszflheI roll carrying arm 3 (Figs. 5and 8) is fixed to a Shaft 6 enlarged at one end to form a yoke 7. The yoke is pivoted to swing vertically upon trunnions 8, havin bearings in a ring 9. The ring is adapte tol rock within the annular frame 10, which may have ball bearings 11. The frame 10 is fixed to a rock shaft 12 which is mounted in a bracket 13 fixed to the frame. 1. Below the. bracket 13 there is secured tothe rock shaft 12, an' arm 14 (see Figs. 1, 2 and The outer end of the armis connected by a universal joint to a rod 15 which is connected by' another universal joint to an arm 16 secured to a shaft 17 mounted in bearings on the frames l1 and 2. A lever 18 is also fixed to the Shaft rock shaft 12, and thus the various positions of the roll across the shoe sole may be obtained.` The roll 4 (Figs. 5 and 6.)' is mounted in a fork 21 which is carried by a slide block 22. The block 2 2 is adapted to slide in ways 23 in the arm 3. A bar 24 connects the block with a lug 25 projecting from a sleeve 26 (Fig. 8) which is 'held betweenl coliars on a shaft 27. The shaft 27 passes -through 'theshaft 6, and at its end (Figs. 1l

.and 7) has a universal joint 28 connected to the outer member 29 of a spring coupling. The inner member of the spring coupling is connected by a form 30 to a second fork 31 which engages a slotted segment 32 which is secured to and adapted to rock about a shaft 33. An arm 34 integral with the segment 32 is connected with an arm 35 extendling from a strap embracing the eccentric 36.

The eccentric is secured to a shaft 37 suitably mounted on the frames and having a pulley 38 (Fig. 1) adapted to be driven y a. belt from a pulleyl 39. It will be seen that upon rotation yof the eccentric a vibratory movement will be imparted to the roll through the connections described. The spring coupling, which is of the usual telescopic construction, is interposed betweenslotted segment 32, a' bar 40, the lower endv of which is connected to an arm 41 of a bell crank lever (see Fig. 9). The lever is loosely mounted yon a shaft 42 held in bearings on the

frames

1 and 2. The other arm 43 of the bell crank carries a cam roll 44 in engagement with a cam path on one side of a cam 45. This cam path is so formed that motion 'may be imparted to the bar 40 to move the fork 3 1 on the segment 32 from the dead center in line with the shaft 33 to the end of the segment. This will permit variation, under control of the cam.45, in the vibration of the roll 4 ranging from nothing to the extreme throw at the end of the segment 32.

Another motion to be imparted to the roll is the side tip to vary the lateral inclination, as indicated in Figs. 21 and 22 at c, (l and e. This is produced by turning the ring 9 (Figs. 5, 7 and 8) in the frame 10. The ring has ,an end wall 46 to which is keyed a pinion 47 in mesh with a gear 48 pinned to a shaft 49. Thisshaft is mounted in a yoke 50 secured to the frame 10, as is best shown in Figs. 1` 3 and 5. Referring to Fig. 7. theL shaft 49 is connected by a universal joint 51 with one member of a telescopic coupling 52, the other member of which is connected by another universal joint 53 to a forked lever 54. This lever is pivoted at one end in line with the universal joint upon a lug 55 depending from a yoke 56 which extends -over and across the machine as shown in Figs. 1, 3 and 20. The other end of the lever 54 is engaged by a fork 57 on the upper ,35 vend ofa rod 58. yThe lower end of the rod Ybearings 75 on the frame.

is secured by a universal joint to a. lever 59 fixed to a shaft 60 .which extends from one side of the machine to -the other. It will now be evident from the inspection of Figs. 5 and 7 that if the sha-ft 60 is,rocked, the ring 9 will be turned through the gear connections described, Iand this turning mov,- ment will be imparted directly to the roll 4 by means of the arm 3.

Fig'. 20, which is a view similar to Fig. 7, but showing the opposite side of the frame 2, illustrates the actuating means for rocking the shaft 60. It is necessary in order to properly illustrate this mechanism that a small portion of the second sole rolling mechanism be shown. It will be remembered that this is a doubleor twin machine. and that but one side has been illustrated. Fig. 20 shows the rod 58 and also the'lower part of a rod 582 the function of which is in every respect similar to the rod 58, and which actuates the roll tipping mechanism on the half of the machine which has been otherwise omitted from the drawings. The

rod 58 is connected to -the shaft 60 by means of a lever 61 slotted to receive a pin 62 secured to the rod. The rod extends downward and is joined at 63 to an arm 64 of a bell crank lever mounted on a bracket 65 bolted to the frame 2. TheI other arm 66 of the lever is connected by a rod 67 t0 a slotted segment 68. The segment is fixed to the shaft 42, which also carries a rigid lever 69 (see Figs. 7, 9 and 20). The lever 69 has a cam roll 70 in engagement with a cam path on the cam 45. This cam path is properly shaped to produce the desired amount of side tip of the roll 4 as it progresses along the shoe. This will ordinarily consist of the positions indicated by 0, d and e in Figs. 21 and 23. Vhen rolling the side areas of the sole with the roll in the position d, Fig. 21, the lateral angle of the roll is greater at the shank than on the forepart. The angle at the shank will vary in accordance with the style of the shoe'being operated upon. In order that various angles maybe produced at this point, there is an auxiliary tipping device under control of a cam upon the outside of the machine so that it may be easily removed and another one substituted when the style of the shoe operated upon is changed. The connections bctween the bar 67 land the segment 68 consist of a block 71 pivoted to the bar. 'A link 72 joins the block pivot/to an ear 73 adjustably secured to a slide bar 74 mounted in The slide bar also carries a fixed sleeve 76 which is connected by a link 77 with a block 78 adjust-- ably secured in a T slot in a segment 79.

The segment has a stud 80 which extends through a bearing 81 and has .'xed thereon a lever 82 inthe end of which is carried a roll engaging a cam path in a cam 83.

l form movement Upon rotation of the cam 83 the block 71 will be moved in the segment 68 toward or from the center of oscillation, that is, the shaft 42. The sefgment 68 is given a unior all styles of shoes to vary the lateral inclination of the roll l certain 'timos in the operation upon the shoe,` and the extent to which the roll is affected by the movement of the segment if: Varied and controlled by the cani S3 in accordance with the style of the shoe being operated upon. The cam 83 may be readily changed for dierent styles, as it is on the end of its shaft and outside of the machine. Itis not always necessary to change title fam `f0r each style, as the adjustment of the block 78 Will often furnish all the variations needed. The cam 83 may be used to 'prodi` c variations in the side tip of, the roll at i desired part of the shoe, as 'well as at tu Shank.

In order that the roll may always exert a pressure toward the shoe, and also to pro vide means forvarying the pressure of the roll upon the shoe, an adjustable spring tension is provided. The ring 9 has a, project` ing arm 301 (Figs. 3 and 5) which carries, loosely pivoted at its ends, two rods 302.

Surrounding the rods and engagedv between:

nuts303 and ears 301 formed on the hub of the arm 3, are two springs 305. j By adjusting the nuts 303 the pressure of the roll may be varied, and this pressure will always be toward the axis of rotation of the arm around the shaft 6.

` Anotlier'angular motion imparted to roll -1s that for varying the angle o; tre rolf with the longitudinal center line or the so a, which is indicated in Fig. 22 at e, f' and The mechanism for producing this motion :s closely connected with the mechanism lor giving the roll an angular vil'uation. The -yoke 21, Which carries the roll Al, has a stud 84 (Figs. 5 and 6) which passes tlirough the block 22 and has fixed 'thereto a bevel gear 85 in` mesh with. a second gear S6. This gear is mounted on a short shaft journaled in the bearing 87 which is mounted on the slide. A telescopic joint 88 connects the gear sha-it With the shalt 89 mounted on the erm 3. The rear end of this shaft has abevcl gear 90 in mesh wi th a gear segment 91 supported by brackets 02 on the arm 3. A forked arm 93, integral with the segment 91, is provided 'at its lower end with rolls engaging an annular groove in a spool .0l which is mounted on the'shaft 6. The spool is free to slide longitudinally of the shaft. but is connected to rorzo {licrouitli liv a key.` )l linl" 8f? attached ai, enc end 'to cars ou die e l 94 and at tbc other to the lower end of two levers 10 pivote-'i on the ring 9. Near the middle of these two levers are two rolls 97 which engr a spe 98 freely mounted on the shaft 27 8 and 10). The spool 9S is connected by two links 99 with one arm of a bell crank lever 100 which is mounted on mts formed on the annular frame 10 The other arm of the bell-crank forked and carries rolls to engage a spool 101 i lv nwuuled on the shaft 12. This scm" Zug 102 which is connected by a link to a similar spool 101 on the lower end of the shaft 12 (Fig. i). The spool 10i is engaged by rolls cairied on one arm of a bell crank lei er 105 which is mounted upon a ska fl, carried by the casting 10F) (Figs. 7 andV 9). The other a ,25; of the boil crank 105i connected by a link 10T with a block. 103 mounted in a T slot 109 in the slide 110. There also connected to the block 108 a link 1.11 which is joined to a hier lli? lineal on a shaft 113. The Shaft 1in f across tbc war ci the machine am; .irl in the bearings carried by the two frames. A lever 111 secured to the shaft 113 has a cam. roll 115 in engagement with a cam path on a cam 116. The action of 'the cam path will more the block 108 up r r down in the T slot 109, and as this slot is set at an angle as shown in Fig. i', a motion vwill be imparted to the bell crank 105, and thmugh he connections described, to the roll el. which will be rocked about the stud 84, "llic telescopic joint 88 is necessary to permit, the iibratory motion" of the slide which. has been described.

The angular vibration of the roll is produce-d by the following mechanism: The slide 11,0 is carried on a rod 117 secured in the 'ffffff f t link 118is pivoted at oneend 'f ,il fle #lier end is forked 'f 'rient 119 which is out a pivot 120 also 1053. An arm 121 neat incl is connected ,anni carried by an V .Quilted on the shaft 37. The .Y tion f link 118 in the slotted segment 110 may be varied by means of a link 124 carried at the end of a lever 125 mounted oo the shaft 113. The hub of the lever lf' has a coef-d arm 126 having a cam roll 52T in ong Y @ent with a cam path on the cam 110. 'flic levers which are mounted'on the sha-fais 12 and 113 may be yoked across to operate the side of tl'ie machine which is not shown in the drawings, as is indicated in Fig. 9. It is apparent that with the link 11el in the position shown in Fig. 7, that is, in line with the pivot 120, no motion Will be imparted thereto by the eccentric 123 and the connections described, but as the point of connection between the link 118 and the ted segment is lifted by means of the cam 11G, a rarying rccij'n'ocatory motion will be 'imparted to the slide 110. This motion will be transmitted through the block 108 to the roll Il, where it is reduced to an oscillation of the roll about its point of conmasias tact with the shoe, that is, about the stud 84.

it to the upper, it is desirable that the higher yend of the roll shall be in advance of the lower end, as is indicated by full lines at e in Fi 22. The object of this is that the roll shall lave a wiping action to turn the sole over the edge of the shoe. At this time the roll Will be oscillating under the action of the leccentric 123, and the aXis of the roll will be inclined at its upper end in the direction in which the Work is progressing along the shoe, by moving the block 108 above or belsovs7 its normal position in the slot 109. This is produced by the cam roll 115 and the connections to the link 111, as has been described.

The jack, Which has been generally designated by 5, consists of a slide 128 having mounted therein a rod 129, as shown in Figs. 11 and 12. The rod is threaded to engage a sleeve 130 which slides inside the slideI 128 and has a finger 131 projecting through a slot in the top of the slide. A second finger 132 is fixed to the slide. By means of a hand Wheel 138 on the rod, it may be turned to spread the tWo fingers 131 and 132 to engage the ends of a slot in the last 134.. The lslide 128 is mounted in Ways on a block 135,r which in Aturn is mounted in ways inthe jack carriage 136. The Ways for the slide 128 enable the position of the shoe to be adjusted when the Work is changed from a small to a large sized shoe. A clampin screw 137 is threaded in a lug on the bloc 135 to clamp the slide in its adjusted position. Provision is made for rotating the jack to carry the roll around the ends of the shoe by the following construction: The carriage 136, which is preferably formed in two parts held together by bolts 138, has secured to it a ring 139 (Figs. 4 and 17) which has a bearing in a shelf 140 which is secured to the frames of the machine extends across the front. The lower pars; the jack carriage is secured by a pin 141 to a fork on the upper end of a shaft 142, thev lower end of which is supA ported in a bearing carried by a bar 113 extending from one side of the machine to the other. The lower end of the shaft 142 has secured to it a bevel gear 144 Which is connected through a second gear 145 with a shaft 146. The shaft 146 is supported in bearings in brackets il? and 148 2). The shaft has securedthereto a gear 14S) which is in mesh Withwa gear 15() supportcd upon a shaft 151 supported in bearings on the bracket 148. The construction of the gear 150 is shown particularly in Figs. 18 and 19. The gear is shouldered on the 1nside to provide bearings for a disk 152 on one side and a plate 153 secured thereto on the other. In a suitable pocket in the disk 152 is mounted a spring pressed pawl 154.

There are a number of notches 161 formed on the inside of the gear 150 to engage the pawl when it is actuated in one direction,A that is, if the disk 152 is rocked, the gear 150 will be given an intermittent motion in one direction. The disk 152 has an arm 155 (Figs. 1 and 4) which is connected by a link 156 with a lever 157 having a cam roll 158 (Fig. 1) in engagement with a cam 159. Upon rotation of the cam, the disk 152 will be rocked and an intermittent motion imparted to the gear 150 which is transferred through the connections described to the shaft 142. The distance between the notches in the gear 150 is sufficient to impart a rotary motionof 180O to the shaft 142; that is, the shoe in the position shown in Fig. 1 will be given half a revolution and the toe will then point to the rear of the machine. This motion is provided in order that the heel or the toe of the shoe may pass beneath the roll when it is acting upon the edge of the sole. The reciprocation of the jack below the roll is obtained through a segmental gear 165 mounted on the pin 141 between the sides of the jack carriage. This gear is in mesh with a rack 166 secured to the lower side of the block 135. An arm 167 formed integral with the segmental gear is connected by a link, 168 with a spool 169 freely mounted on the shaft 142. The spool 169 is engaged by rolls on a forked arm 170 which is secured to a slotted se ment 171 (Figs. 1 and 4). An adjustable tblock 172 is mounted in the slot of the segment and is pivotally connected With a link 173 joined at 174 to an arm. 175 pivoted on a fixed part of the frame. The pivot 174 is also the bearing for a cam roll 176 which is engaged in a suitable cam path on the cam 159. It is apparent that rotation of the cam rfill rock the segment 171 about its shaft an amount depending on the position of the block 172, and this motion will be transmitted to the segmental gear which Will move the block 135 in its ways in the ack carriage.

vWhen the roll leaves the toe of the shoe it should bp supported in proper position to again ride up onto the solo when the motion of the ack is reversed. This is accomplished by a mechanism which arrests the downward movement of the roll after it has dropped sufficiently to roll over the edge of the sole at the point of the toe. This mechanism comprises a controlling rod 178 which may be adjusted in accordance with the position of the toe of L1e shoe operated upon and determines the time of operation of the supporting mechanism. The rod is provided With a laterally projecting finger 177 v for engaging the toe of the shoe, and is suported in bearings in a frame 17 9 (Figs. 11 and 16). The linger 177 may be swung from the horizontal position shown in dotted lines in Fig. 16 toward the shoe, and when in this frame, thus connecting the 'rod with the frame. A stop 182 is 'provided to engage the rack and hold the rod in its horizontal position. 'lio frac- 179 is mounted t slide upon a rod 183 which is secured to the frame 1. A link 184 connects the frame with an arm 185 secured to a shaft 186 (Fig. 1) mounted on the .frame of the machine. A second arm 187 is secured to the shaft 188 and engages a pin 188 projecting from the forked arm 170. This is indicated in broken lines in Fig. L The connections just described between the arm 170 and the frame 179 are such that the frame moves on the rodA 183 at the same time and through the same distance that the jack is moved, that is, the rod 178, after being set, will always move so as to remain in the same relation to the shoe. The rear end of the rod 178 will engage a finger 189 when the frame 179 is moved a suili'cient distance to the right in Fi g. l1. The finger is so arranged that the roll 4 will be at the end of the toe when the rod engages the linger, and will be about to drop from the toe on a continuation of the movement. The finger 189 (Fig. 13) is attached to a valve stem 190 having pistons 191 inside the tube 192. Compressed air from any suitable source is admitted to the tube by a pipe 198, and when'the stem 190 is move-:i to the right the air will pass through the ports 194 into a chamber connected with a pipe 185 which leads to a cylinder 196. The cylinder has a piston 197 with a stem engaging one end of a lever 198 which controls the rod supporting device, (Figs. 14 and 15). The lever is pivoted at 199 im a casting "l secured to the frame 1. The other end he lever 198 is connected by a link 201 with toggles 202 which are mounted on the jaws 203 pivoted on the bracket 204. The bracket 204 carries a series of plates 205 which are in slidin contact with plates 200 fixed in a yoke 207 carried by a rod 208. The upper end i' the rod 20L below the arm 3, as shown in Fig. 1, and. valways ic. contact therewitli. Therefore, if at the proper time compressed air is admitted to the cylinder 196 the jaws 203 will grip the plates 208, and the rod will be held in its position to support the weight of 'the am f-hen the 'passes from thevtoe of the shoe.

It is desirable that the roll shall have a slight drop when it passes from the toe, to properly roll the sole at the extreme point. Therefore provision is made for a slight lost motion in the supporting device. This is provided by mounting the bracket 204 upon fissa,

a stud 209 which is held in a bearing in the casting 200. The bracket has ears 210 which slide upon two rods 211 secured at their lower ends to the casting 200. Springs 212 surround each of these rods and normally hold the brackets and parts of the supporting device carried therebyy in the position shown in Fig. 15, but when the weight of the arm and roll is placed on the rod 208, and the jaws are in their clamped position, the bracket will be depressed a slight distance, compressing the springs 212.

ln order that the heel breast of the shoe may be rolled, provision is made for actuating the rod 208 to lift the arm and give the roll vertical motion to operate -upon the heel breast, and also to lift the roll clear from the shoe at the completion of the rolling operation. The lower end of the rod 208 is connected with an arm 213 which is rigidly yoked to an arm 214 on the outside of the machine frame (Figs. 1 and 2). These arms are pivoted on the shaft 17 which has been described. The arm 214 has at its end a cam roll 215 in engagement with a disk cam 216. A spring 217 holds the arm 214 away from the cam so far as it is permitted to do so bythe position of the' arm 3. At the time when the heel breast is to be rolled, pro]ections on the cam 216 will lift or lower the arm 3 to produce they required motion, and at the completion of the work a. greater rise will elevate the arm, as shown in Fig. 1.

The main cams of this machine, Which have been described, are mounted on the shaft 218, having bearings on the

frame

1 and 2. This shaft is driven by a worm gear 220 in engagement with a worm 221 (Figs. 1 and fixed to a shaft 222.v The shaft is adapted to be driven from a main driving shaft 223 extending across the rear of the machine and connected by a pair of' beveled gears 221 with a sleeve 225 sup ported in a bearing The worm 221has a slotted sleeve 227 which is engaged by a similar slotted sleeve 228.. A pin 229 fixed in a collar on the sleeve 228 is constructed to engage a slot in a collar on the sleeve 22. thus `forming a sliding clutch. lVhen the pin is engaged by the slot, `motion will he transmitted from the sleeve 225 to the worm 221.` A forked lever 230 engages the sleeve 28 to impart the sliding motion thereto. The lever 230 is held between collars on a shaft 281 which also carries a lug 282. The forward end of the shaft is surrounded by a spring 283, as best shown in Fig. et. which tends to keep the shaft to the right, that is, with the clutch in engagement.

' When it is desired to disengage the clutch during the operation of the machine, the operator will depress a treadle 234. pivoted to the machine frame, and through the bell crank 235 pull the link 236 to the left. The link is secured at its end to the lug 932. This will slide the rod 231 to the left and disengage the clutch. In order to hold the clutch out of engagement there is a latch 23T pivoted to the treadle lever, one end of which will engage a lug 238 on a fixed part of the frame. iently released by pressing the end near the treadle so that the clutch may be rengaged.

In the usual operation of the machine the cam shaft 218 and the cams thereon would move through a complete rotation to op- An automatic stopping crate upon a shoe. device is provided to stop the cam shaft after each revolution. This comprises a finger '239 fixed to the cam 116 in position to engage the lug Q32 and shift the shaft 231 todisengage the clutch. When the operator wishes to start the machine he Will depress the treadle Q10 which is Xed to the shaft 231 and adapted to rock the shaft (Fig. 4). Thiswill turn the lug 232 out of the path of the linger 239, as is best shown in Fig. Q, and allow the spring to engage the clutch. After yone revolution of the shaftn the linger 239 will contact with the lug and thereby disengage the clutch.

While it is preferred to employ the specilic construction and arrangement of parts shown and described, it Will be understood that this construction and arrangement is not essential, and may be varied or modified without departing from the invention.
