In the illustrated embodiment of the invention a roughly died-out insole 1 (Fig. 1) is secured to-a last 2 which is jacked upon a work support 3 of the saddle and spindle type. The work support 3 is provided with runners 4 which slide on a platen or-table 5 secured upon the upper end of a post6" which is mounted for vertical movement in bearings 7' formed in a bracket 8. The top of the bracket 8 is provided with four slots 9 (Fig. 10) which "loosely embrace four bolts 10 on a. column'll in -ord'er that the bracket 8 may be guided to slide in a fixed In order to feed the work support 3 over the-table 5 and thus transfer the point of operation of the operating means around the insole the'work support 3 is mounted on a leader 12 (Figs; 1 and 15) provided with As shown in Fig. 12

the projections of the-edge of the bottom of the last at the sides thereof upon the plane of the leader coincide with the inside face of the guiding flange. At the toethe projections of the edge of the last bottom upon the plane of the leader fall within the guiding flange. This variation at the toe of the leader is for the accommodation of the toe-box which in a subsequent operation hen the upper having the toe-box within it is lasted to the edge face of the insole in accordance with the method of lasting practised by me the projections of the free edge of the upper upon the plane of the leader will coincide with the inside face of the guiding flange throughout its length. Stated in another way, the projections upon the plane of the leader of the outside edge of thetoe-box secured in position on the toe with a similar gem-18. The bevel gear 18 is connected by a universal joint 19 to a short shaft 20 (Fig. 9) which is connected by a universal'joint 21 to a shaft 22 journaied in the column 11. The shaft 22 carries a worm wheel 23 which meshes with a worm 241 on a shaft 25 also journaled in the column 11. The shaft 25 (Fig. 1) is driven from a short shaft 26, journaled in a bracket 27 on the base of the machine, by a belt 28 which passes over pulleys on the shafts 25' and 26, respectively.

In order to correct the relative position of the operating means and the insole dur ing the transfer of the point of operation of the operating means around the insole to maintain the edge of the insole in proximity to the operating means in the line of feed the guiding flange 13 on the leader is engaged by a cylindrical pin' 29 (Fig. 5) arran ed to engage inside the flange and by gulde rolls 30 and 31 arranged to engage outside the flange. These guiding devices are mounted on supports secured to the bottom of the table 5 and are positioned above the table 5 through ,an opening 32 formed therein. The support'for the pin 29 is a lever 33 one end of which pivots at 34 and the other end of which slides in Ways 35. secured to the bottom of the table 5.

' work table the exterior face of the guiding flange 13 is bevelled as shown at 38 (Fig. 15). Thisbevelled surface is engaged by the frusto-conical guide rolls 30 and 31.

With this construction the guides 29,30 and binding as they traverse the reverse curves of the flange at the shank and around the toe the guide rolls 30 and 31 are journaled on the free ends of links 39 and 40, re spectively, the rear ends of which are pivoted to a lever 11 pivoted at 42 to the bottom of the table 5. The links 39 and 10 are also pivoted to links 43 and 4.4. pivoted to the bottom of the table 5. The guide rolls 30 and 31 are thus supported for movement transve sely of the feed of the leader exactly as if they were supported on a. slide but without the frictional resistance incident to the use of a slide. The rolls 30 and 31 are actuated in a direction to press them against the exterior face of the guiding flange 13 by means of a spring 45. (Fig. 5). At its free end the lever 41 is pivoted to a block 46 which loosely receives a rod 47 pivoted at -18 beneath the table 5. The spring 45 is coiled around the rod 47 and is interposed between the block 46 and a shoulder 19 on the rod.

.With' this constructidnthe spring 45 norand the handle 37 is actuated in a direction to lock the inside guide 29 against the flange, the outside rolls are pushed forward thus placing the spring 45' under compression. The spring 45 yields during the feed of the leader so that it exerts its maximum. and minimum pressures when the rolls 30 and 31 are being transferred around the shank and toe of the leader, respectively. The lever 41, however, inversely transmits the pressure of the spring so that the rolls 30 and 31 are held with a greater pressure against the toe of the leader than they are held against the shank of'the leader.

The tool for trimming the roughly died out insole to the edge of the last bottom consists of a knife 50 (Figs. 1 and 2.) which cooperates with an anvil or foot 51 mounted on a cradle 52. The knife 50 is formedon a block 53 which is mounted on one end of a lever 54 pivoted on a stud 55 carried by the cradle 52. The knife block 53 may be adjusted in the lever 54 by a bolt 56 and then held in screw 57.

The anvil 51 which'extends between the insole and the last bottom controls the height of the work. To this end a coiled spring 58 (Fig. 1) is connected'at'one end to the column 11 and at its other end to a treadle 59 pivoted on the machinebase. Intermediate its ends the treadle 59 is connected to the post 6 by a link 60. Depression of the treadle 59 lowers the work table 5 to permit the insertion and removal of the work. When the treadle is released and the anvil 51- positioned between theinsole and adjusted position by a setthe last bottom the work automatically rises and falls under the influence of the anvil 51 and the spring 58 to maintain the-insole at 'the operating point in the same plane notwiths'tandingthe various slopes on the last bottom. The post 6 is guided in its vertical movement by a plurality of rolls 61, on the post, which work in slots 62 formed in the bearings 7. g

The insole'atthe operating point is held down upon the anvil 51 by a pressure roll or foot 63 (Figs. 2 and 4) which is jou'rnaled on a stud 64. The stud- 66L is carried by the lower end of a slide 65 mounted to 'slide in the cradle 52. The roll 63 is pressed towards the insole by a spring 66 coiled around a rod on the slide 65 and interposed between an arm 67 on the cradle 52 and the top of the slide. a p

In order to vibrate the knife 50 the lever .54 is provided with a cylindrical pin 68 .upon which a block 69, provided with trunnions 70 (Figs. 2 and 3), is loosely held by a cotter pin 7 1. The trunnions 70 support a split yoke 72 (Fig. 3) which is hung on trunnions '73 formed on an eccentric strap 7 4 which embraces an eccentric 75. The eccentric 75 is secured to ashaft 76 which is supported by bearings 7 7 formed in a head 78 secured to the column 11.. The shaft 76 is the armature, shaft of an electric motor 79 secured to the cradle 52 and rotates on an axis passing through the point of operationof the knife. I

During the transferof the point of operation of the knife 50 around the insole it is desirable that the cradle 52 tip automatically to maintain the knife 50 substantiallyv .normal to the insole at the point of operation. To this end a series of ball-s 80 (Fig. are interposed between'a ball race, one member of which is secured to the bearing 77 and the other member of which is secured to the shaft 76. Both of the bearings 77 are provided with ball races-so that the shaft 7 6 is supported in a floating manner by two sets of the balls 80. With this construction the cradle 52 floats on an axis passing throughthe point of operation of the knife 50 and is tipped automatically during the rounding operation by the combined action of the feet 5l and 63 which adapt themselves to the varying slopes on the last bottom. The knife is thus maintained normal to the insole at the operatin point. a

If a belt or gear w eel were mounted on the shaft 76 anddriven from some external .source of power through a belt or gear train the cradlewould become unbalanced and the feet 51 and 63 would be held in a fixed posi tion unresponsive to the varying slopes on the last bottom. By directly applying the power to the shaft 76 through the armature of an electric motor the balance of the cradle is preserved and its sensitive response to the positions assumed by the feet under the influence of the work is ensured.

The knife 50 vibrates in a plane inter' secting the edge of the last bottom at the sides thereof. In order to maintain the plane ofthe knife intersecting the edge of thelast bottom during its transfer around the-toe of the insole notwithstanding the toebox' variation hereinbefore referred-to, the bracket S is moved'on the column 11 to shift the insolesupported from the bracket transversely of the feed. The insole is shifted twice during the rounding operation first to remove the'tool from the path determined by the leader and then to return the toolto said path. The knife is thus caused to traverse ..a detour at the toe of the insole coterminous with the path determined by the leader. The bracket 8 isshiftedby an eccentric 81 (Figs. 8 and 9) on a'vertical shaft 82 journaled in a sleeve 83 which is mounted for rotation in bearings 84. The eccentric 81 has a strap-and-link connection 85 with a bridge. 86 on the bracket 8. The shaft 82, normally inoperative, is driven at the proper intervals through a clutch, one member of which consists of adisk 87 on the shaft, and the other member of which consists of a clutch bod 88 surrounding the disk 87 and carried y the sleeve 83.- A cylindercarrying disk 89 is loosely mounted on a collar 90 carried by the shaft, 82, and this disk is provided with a laterally-extending fiangewhich lies between the inner surface of the'clutch member 88 and the disk 87. The disk 87 is provided with a'series of recesses in which the clutch cylinders 91 are carried. The disk '87 is provided with a series of wedging surfaces 92'for cooperating with the cylinders in connecting and disconnecting the clutch members. The cylinder-carrying disk 89 and collar 90 are connected by a spring 93 which tendsgto rotate clutch member 88 and bind the clutch mem bers together. When the clutch members are engaged in the manner described the shaft 82 is driven through a bevel gear 94, on the sleeve 83, which is engaged by a bevel gear 95on the shaft 22. The clutch is normally held out of action by means of a controlling stop in the form I of a modified bell crank lever 96' (Fig. 8-) one end of which normallyprojects into position torbe engaged by .a radially projecting lug 97 on the cylinder-carrying disk 89 and prevents rotation of the disk. Vfhen the bell crank lever 96 is withdrawn, the spring 93 acts to immediately move the are wedged between the surfaces 92 and inner surface of the clutch body 88, and securely unite the parts of the clutch so that insole by the action of controlling devices on the leader, and the bell crank lex er 96 is automatically returned into position to disengage the clutch when the clutch has made one-half a revolution. In the construction shown the bell crank lever 96 is actuated in a direction to withdraw it from the lug 97 by a coiled spring 99 connected at its ends to the column 11 and bell crank lever, re-

spectively.

Thebell crank lever 96 is held in lugengaging positionagainst the tension of the s rin"99 b a fin er 100(Fi s; 6 and 7) P g y g g arranged in the path of travel of the bottom of the guiding flange on the leader. To this end the'finger 100 is loosely mounted on the lever 33, hereinbefore described as the support for the inside guide pin 29, in position forest on the elongated end 101 of a bell crank lever 102 (Fig. 6) pivoted beneath the table 5. The lower end of the vertical arm of the bell crank lever 102 is provided with a roll 103 which rides in a vertical slot 104 formed in a yoke 105 (Fig. 9) carried by the modified bell crank lever 96 which .is pivoted on abracket 106 (Fig. 8) carried by the column 11. v

-During the operation of the knife 50 on the sides of the insole the finger 100 is 40.P

res'sed downwardly by engagement with the bottom of the guiding flange 13, and thus maintains the lever 96 engaged with the lug 97 against the tension of the spring 99. When the knife 50 reachesthe point A (Fig. 12) the finger 100 rides into a depression 107 (Fig. 14) under the influence of the spring 99thus freeing the lug 97 and cansing the shaft 82 to be driven through the clutch members. The finger 100 is reset by an incline 108 (Fig. 14) on the leader so that the bell crank lever 96 is returned to a position where it may engage the lug 98 and throw the shaft 82 out of operation after it has completed one-half a revolution. The insole maintains the position to which it has been shifted until the finger 100 rides into a second depression109'on the other side of the leader and the insole 1 is then shifted back to its original position which brings the knife 50 back to the path determined by the leader at'the point B. The finger 100 is again reset by the incline 110.

In order to hold the bracket 8 accurately in its out and in. positions the collar 90"(Fig. 9) is provided with a pair of lugs I to engage the pinion an cial care or attention the pinion 14 is yield- 130.

111 and 112 (Fig. 8) which are engaged successively by a spring-pressed dog 113 pivoted on a bridge 114 carried by the col umn 11. The dog 113 yields to permit the passage of the lugs during the rotation of the shaft 82 and thenslips behind one of the lugs when the clutch members are disen- ,gaged. The shaft 82 is held by the dog 113 and bell crank lever 96, in a definite angular position thus accurately defining the limits for the shifting movements of the bracket 8. I In order to indicate to the operative the position of the bracket 8 the top of the column carries a pivoted pointer 115 which is normally held by a leaf spring 116 against a mark 117 to show that the bracket 8 is in its out position in which. position the knife 50 traverses a path determined by the leader. When the bracket 8 is shifted to its in position in which position the knife 50 traverses the detour the bracket 8 engages a screw 118 on the pointer 115 and swingsit against the tension of the spring 116 to the mark in on the column 11.

To provide the cylinder-carrying disk 89 with sufiicient momentum to insure a posi- I tive engagement between the bell crank lever 96 andthe lugs 97 and 98, the lower end of the shaft 82 is rovided with a gear 119 which meshes witli a gear 120 loosely mounted on a short vertical stud 121 supported from the bridge 114. Mounted to rotate with the gear 120 is a fly-wheel 122 which provides the cylinder-carrying disk 89-with suflicient'momentum to properly engage the lugs 97 and 98 with the bell crank lever 96.

In order to prevent the tripping of the finger when the leader is withdrawn from the machine the link 40 (Fig. 6) is provided with a cam 123 which, as the link 40 moves back to its original position when the guide pin 29 is unlocked from the leader, engagesthe bell crank lever 102 and pre vents it from moving in a direction to rclease the bell crank lever 96 from the lug 97. A spring 124 coiled around the finger 100, and interposed between the lever 33 and a head 125 on the finger 100 insures the de.

pression of the finger 100 below the surface of the platen whenno leader is in the machine. The spring 124-also insures the engagement of the head 125 with the elongated end 101 of' the bell crank lever 102 during the makin and breaking of the-toggle to engage an disengage the guide pin 29 and the leader.

In the .machines heretofore used in my system of shoe manufacture it has been necessary for the operative to carefully position the leader against the driving pinion-to insure the rolling contact of the teeth on the pitch line. In order to ermit the operative d leader without spe gagementwith the leader. The spring 128 also permits the pinion to automatically adapt itself to any irregularities in the ingly mounted so that in the event that the operative positions the faces-of the teeth on the-leader and pinion in contact the pinion will automatically find its rolling contact a stop 1.26 on the post 6 by a plunger 12?.

loosely carried by the table '5. Coiled around the plunger 127 is a spring 128 which is interposed between the table 5' anda collar 12.9 on the plunger. The plunger is screw-threaded at one end to receive a nut 130 for limiting the position of the plunger. With this construction the, spring 128 will yield when the operative positions the face of a tooth on the leader against a face of a tooth on the pinion. Then when the pinion is rotated to drive the leader the spring 128 presses the pinion into proper. drlvingeir teeth on the leader during the drive thereof. The shaft 26 (Fig.11) is driven through a friction clutch from an electric motor 131 secured to the base of-the machine. armature shaft 132 carries a friction disk 133m0unt'edadjacent a friction disk 13a on the shaft 26. As well known to those skilled in the art it ispossible to provide a magnetic center for the armature shaft.

132. That is, while the shaft 132 is free to move longitudinally underpressure applied to one end of theshaft it must always return to a definite central position upon the release of the shaft from endwise pres sure. Accordingly, advantage is, taken of this magnetic center to provide a novel starting and, stopping mechanism for the machine. chine is provided with a rock shaft 135 having a vertical arm 136 projecting therefrom. The upper end of the arm 136 carries a block .137 arranged oppositethe rear end of the shaft 132.- To rock the shaft" 135 andthus engage the block 137 with the shaft, 132 the rock shaft 135 carries a second vertical ,arin 138 which, i'sconnectedby arod 139 with a foot "treadle 14:0 pivoted on the base of the machine. When the foot treadle 1&0 is depressed the shaft 132 is moved longitudinally thus engaging the disk 133 with the disk 134. When the treadle is released the shaft 132 immediatel returns to its magnetic; center thus withdrawing the disk "133 .froin the disk 134. At the same time-a spring-141 amnected at one end to the rod-139, and at its other end to the column 11 forcibly applies a brake 1&2 on the treadle lever to the disk 134:. i

In operating the machine-the treadle 59 "is ,depressed to lower the table 5. The

The

To this end the base of'the ma- -;ing the transfer of the point of operation died-out insole attached thereto is then placed on the table with the guiding flange on the leader interposed between the inside and outside guides. The handle 37 (Fig. 5) is then actuated to lock the inside guide .against the guiding flange thus clamping the leader between the guides under the influence of the spring i5. This movement of the handle 37 releasesthe bell crank lefer 102 from the cam 123 (Fig. 6)

thus causing the spring 99 (Fig. '8) to press the finger 100 against the bottom of. the guiding-flange on the leader. The insole is now positioned in the machine with the insole adjacent the operating point gripped between the roll 63 and anvil 51 which is inserted between the bottom of the last and the insole at approximately one breast corner. The knife 50 having been thrown into operation and the treadle 140 having. been depressed to actuate .the pinion 14: the insole is trimmed to the edge ofthe last bottom until the point A (Fig. 12) is reached. At thi'spoint the finger 100 rides into thedepression 107 thereby freeing the lug 97 and throwing the shifting mechanism into --operation to shift the insole and thus cause the knife 50 to start on its detour (Fig. 12). The finger is immediately reset by the incline 108 so that the bell crank lever may engage the lug 98 upon the completion of a half-revolution of the clutch and throw the shiftiiig mechanism out of operation. The

knife 50 continues to cut the insole on a line 100 parallelto the path determined by the toe of the leader until the point B is reached when the finger 100 rides into the depression 109 (Fig. 14) and the shifting mechanism is thrown into operation .a' second time to return the knife 50 to the path determined by-the leader. The finger 100 is again reset to hold theshifting mechanism inoperative in original position. Dur- 110 of the cutter around the insole the cutter 50 is vtipped automatically about its point of operation-to maintain it substantially nor- -.ma'l-to the insole at the point of operation 'andthe'insolerises and falls under. the infiuence jof the spring 58 and anvil 51 to maintain the bottom of the last adjacent the operating pointsubstantially in the lane of" the anvil. At the completion of the out the treadle 140 isreleased to stop jthe drive for the pinion 1A and the treadle 5.9 is'depressed to permit the finished work to be wlthdrawn from the machine. .While the invention has been' illustratedand described in connection with a sole roundinw machine it will befapparent :to* .those skilled in the art'that the features of the invent-ion may be advantageously employed in performing other operations in the manufacture of shoes and parts thereof 13ceral objects of the present invention in view,
