Except aschanged and modified in embodying the present invention in a machine adapted to set the edges of shoe solesrthe work supporting ack is substantially that disclosed inthep'ending appli- 1918;:Serial No.fl269,076, while it is moved and controlledin a manner similar to that in the machine shown and described in application Serial No. 355,583, filed February 2, 1920, in thename of'Alfred R. Morrill.

The edge setting n'iechanism of the machine comprises a vibratory carrier 2 (Figs. 2, 8 and 4), upon which are mounted the edge'settingtools. The carrier 2 is-secured to the forward end-of a slide 4, mounted for forward and rearward movements in a guideway in a block 6, pivoted onthe lower r secured in a bracket 10 attached to a carriage 12; The block 6 is held in position on the shaft 8 by means of abolt 14 (Fig. 5)., upon the upper end of which is threaded a nut 16.

- The vblock G is rapidly oscillated on the shaft 8 during the operation of the machine to impart vibratory or oscillatory movements to the edge setting tools. Oscillatory movements are imparted to the block 6' from a 18 journaled in bearings in the through a pitman 20 pivotally carriage 12 2 an arm 22 (Fig.

end an eccentric strap 24 surrounding an eccentric 26 formed on the lower end of the shaft. The shaft 18 is driven through intermeshing spiral gears 27 and 28'from a horrzontal shaft 30 which constitutes the main shaft-of the edge setting head. The main shaft 30 is journaled in bearings formed on l the carriage 12 and is driven from an electric motor indicated at 82 secured to said carriage. j I

Upon the forward end of the carrier 2 is mounted an edge setting tool 34- for operating on the sole edge about the forepart of a shoe and an edge setting tool 86 for operating on the sole edge along theshank. The slide 4 is acted upon by a coiled spring which tends to force the slide forwardly so as to hold the edge setting tool which is in-op erat1on,'1n yielding contact with the sole the bracket 10 and a collar 14: securedto the rod, the spring tending toiforce the rod and tie shde't forwardly. Theforward movement ofxthe rod under the action of the,

spring is limited by a stop collar 46. secured to the rear end of the rod..

7 The force ex erted by the spring 40 may be adjusted by adjusting the sleeve 42.

To enablea shoe to be located and held in operating position with relation to the edge setting tools," the machine is provided with a work table or guide 18 arranged to engage in the crease between the upper and the projecting margin of the soleof a shoe. The

work table is secured to an arm 50 on the frame and sarranged to extend in front of the tool which is in operating position as clearly shown in Figs. 3, 4 and 5. c

The proper burnishlng or setting of the edge of a shoe sole usually requiresthe use of a different form of setting tool or set:

ting the edge about the forepart of the Sole from that which'is employed in setting the edge along the shanln In the present machine the setting tool 3% is especially formed for setting the edge about the for-epart while the setting tool 86 is especially formed for setting the edge along the shank. To enable the setting tools 3d and 36 to be moved alternatively into position to set the edge of the sole without changing the position of the jacked shoeor while the shoe remains in op,- erative position with the table 48 engaged in the-crease between thenpper and the projecting margin of the sole, mechanism is pro 'vided for adjusting the carrier 2 to shift the position of the forward end of the carrier both in a direction transverse to the plane of the sole' and also in 'a'direction toward and from the sole edge. struction the carriage 12 is eccentrically mounted in abearing in a rotatably 'adjustable supporting ring 140 which in turn is mounted to rotatein a bear ng or raceway of the machine. Duringthe adjustment of the ring 140 the carriage 12 is vheld from turning with the ring and a rotary movement 1s also nnparted to the carriage the bodily movement given to the carriage by the ad ustment of the rm g 1&0 and the rotary embracing an eccentric 148 secured to a roclt In the illustrated con-5 formed by the arcuate arms 142 on the frame of which is secured an eccentric strap 14'? l pivoted on a shaft 82 and a ball endedflink die and t'otip the shoe in this direction by means of a cam lever 86 pivoted on the shaft 0 locked in position.

84 connecting one arm of the lever with the said support. The support 68 is swungflaterally' of the machine to impart similar movemen ts to the lower end of the ack spin- 82 and a link 88'connecting one arm of the cam lever with an arm on'said support. The

Wheel is rotated to impart rotary movements to the ack spindle and lateral turn ing movements to the shoe by means of a cable 90 passing about the wheel, about the guide pulleys 92 and 94 mounted on the carrier 66 and over a stationary guidepulley 96. One end of thecableis secured a pulley 98 mounted to rotate on a stud 100 and to the other end of the cable is attached a weight 102. Rotary movements of the pulley 98 are produced and. controlled by means of a cam lever 104 pivoted on the shaft 82 and connected to the pulley through a gear segment 106 and a gear 108. Each of the cam levers 80, 86 and 104.carries acam roll 7 arranged toengage a periphery of one of a series of cam disks mounted on a shaft 110. The mechanism for actuating the yack to impart feeding movements to the shoe comprises a feeding lever 112 pivoted at 114 on the frame and a link 116 connecting sa1d le v'er with the toe end of the jack. During the edge settmg operation the feedlng lever 112 is swung toward the left 1) toactuate the jack to advance the marginal portion.

of the shoe bottom past the operative edge settingtool. The mechanism for' actuating the, feeding lever comprises an erm 118 pivoted at 120 on the frame and pivotally connected links 122 and 124 connecting the arm.

118 with the feed lever. The arm 118 is actuated through a-link 126'from a cam lever 128 pivoted on the shaft 82 and carrying a cam roll arranged to engage the periphery of a cam disk mounted on the cam shaft 110. The path of the connection between the links 122 and 124 is controlled by an arm 130 pivoted at 182 on a lever 134 hereinafter termed the fulcrumcarrying lever which is pivoted at 186 on the frame. During the operation ofthe machine'the fulcrum carrying lever'is 1 V hen shoe is placed in the machine, howeverythe fulcrum carrying I lever is unlocked and is free to be adjusted by the placing of the shoe in position inthe' machine to startthe operation. V In changing from one size of shoe to a smaller size the fulcrum carrying lever'134is swungto thej left while in changingfroin mesmeof shoe to a larger size the fulcrum carrying lever, swung to the right. The adjustment of the pivot of the controlling arm 130 pro duced by'the adjustment ofthe fulcrumcan rying l-everadjusts the amplitude of move.- 1.

ment imparted-to the feeding lever for the size of the shoe to be operatedu-pon.

In order that the jack actuating feeding mechanism may operate to advance the margmal port on of the shoe bottom past. the edge setting device always at the same uni:

form rate regardless of the size of the shoe,

the speed of thecam shaft 110 is adjusted in accordance with the. size of the shoe to be operated upon. This constant rate of feedcauses a uniform rubbing actionof theedgesetting tools for .shoes of all sizes, and this,

by choosing'the' proper, rate, of oscillation of the tools, may be maintained at the most effective degree forfinisliing thesole-edge.

The adjustment of the speed of the cam;

shaft'is effected upon the depression of the operation mechanism controlled from the fulcrum carrying lever.

-90 starting treadle. to start the 'machine into The mechanism for driving the camshaft 110 comprises a gear 172 secured to the lupper end of said shaft and arranged tobe driven from a gear 174 formed on the lower end of a sleeve 17 6 through a train. of gears 178,180, 182,184, 186 and 188. The sleeve 176 is driven from a shaft 190 through a variable speed ratchet and pawl transmis S1011 mechanism indlca-ted'as a whole at 192 in Fig. 14.

.TT'h'e shaft 190 is driven from a shaft 194 through a toothed clutch 196. The'shaft 194 in turn is driven through intermeshing spiral gears 198 an'd200 from the driven member 202 of .a friction clutch which constitutes the main driving clutch of the ma-,

chine. The driving memberof the clutch indicated at 204 is secured to'the main driving shaft 206. During the operation of the machine tl1e .m'embers-202 and 20-4 of the main driving clutch are engaged and the cam shaft 110 is driven through .the connections described at a speed depending upon the adjustment of the ratchet and pawl transmission mechanism 192. r The trans- IIllSSlOD mechamsm 192 is controlled by means of anadptstable ring 208 pivoted at r 210 on the frame. The position of the ring is controlled from a longitudinally movable cont-roller bar 212 through connections com prising an arm 218, a rock shaft 214, and

an arm 215. i The left hand end of the con troller bar 212 (Fig. 12) is movably supported by a lever 216 and a link 217 and is formed with oppositely inclined surfaces 218 leading to a recess 220 adaptedto re-.

During this movement of the lever 314:. the slide 318 engages the'pro jection on the bar 322 and the bar is actu ated to swing the ack forwardly out of "the lever 4-00 and is normally held by a stud 406 mounted on an arm L08 secured to the rock shaft- 326. The dog 404 has a limited-pivotal movement with relation to spring in engagement with a stop formed on the lever in the positionshown in Fig. 16. lVhen the lever 306 is swung forwardly the projection on the dog L0 is carried into position to be engaged by the stud e06. As the arm 408 is swung to the left during the first half revolution of the eccentric, the stud 406 engages the projection on the dog and swings the dog until the stud. passes by the. projection. As the arm 408 swings back to the right during the last half revolution of the eccentric the stud lOG again engages the projection on the dog. The engagement of the dog with the stop on thelever 400 prevents the dog from swinging under the action of the stud and the lever 4:00 is actuated to swing the lever 396 rearwardly to its normal position. Thismovement of the lever .396 swings therod 3'26 rearwardly, thereby disengaging thepro ection fronrthe projection 392. I I I From an inspection of Fig. 12 1t \Vlll be noted that the projection st and the pro ec- "tion 308 are so constructed that these projec- 3 tions, when engaged with the lever 296, will if end of the forepart of the shoe is reached.

The block 312, however, is so constructed that .the right hand end of the lever 296 when engaged by the block is held in rearward position during a cons1derable part of a rotation of the gear 172. In stopping-the machine at the completion of the operation 7 therefore, the left hand end of the lever 292 is held in forward position until the lever 370 is actuated by the rod 376 to engage the eccentric actuating clutch. Thus the jack remains in its rearward or operating position with the table is engaged in the crease between the welt and upper of the shoe when p the machine is stopped at the completion of the operation on the side of the shank first acted upon and on the forepartv and the jack is swung forwardly out of operating position when the machine is stopped at the completion of the operationon the shoe.

During the operation of the machine on the shoe the cam shaft is driven through the part of a revolution, and after the main driving clutch has been disengaged :of the lever der formed on the projecting portion of the as during the normal. operation of the ma chine through the ren'iaining-part of a revolution to bring'the same to its initial or starting position. During this movement of the cam shaft, after the operation on the shoe has been completed the jack is turned through half a revolution in a direction 0p posite to the direction in which it is turned durinthe normal operation to bring the jack to its initial or starting position. The cam shaft is rotated through the remaining part of a revolution a'fter'the disengagement of the main clutch by the endwise movement of the lever 296 imparted there to by the movement of the bell crank lever 300.

' The bell crank lever 300 is pivoted at 410 and is connected by a link 412 with the arm 328 As the arm 328 is swung forwardly (Fig. 12), the lever 296 is carried to the left beyond the proje'cting'portion of the contact block- 312 bythe movementof the bell crank lever 800, and as the arm 328 is swung back rearwardly the lever 296is'carried to the right by the movement of the bellcrank. By the engagement of the end 296 with an abutment or shoulcontact block 812 during this latter movement of the lever, the gear 17 2 and the cam shaft are turned through the remaining part ofa revolution to bring the same to starting position. v
