SOLE ROUNDING AND CHANNELING MACHINE.

Specification of Letters Patent.

Application filed November 29, 1901, Serial No. 84,069. Renewed October 5, 1911. Serial No. 653,055.

Tooll who)? it may 0011mm Be it known that I, Arcana B. Fownnn, a citizen of the United States, residing at Boston, in the count of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Sole Rounding and (lhanneling Machines; and I do hereby declare the following to be a. full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention reiates to sole rounding and channeling machines by which the edges of the sole of a shoe are trimmed or rounded or a channel cut in the outer surface of the sole or both theseoperations performed simultaneously.

In rounding and channeling a sole which has been placed upon a shoe and temporarily secured thereto, which operation is termed in the art laying the sole, it is cus tomary to vary, at certain portions of the sole, the distance of the cuts produced by the rounding and channeling cutters from the inseam, or the juncture of the upper with the Welt or sole. For producing this result rounding and channeling machines, as heretofore constructed, have been provided with a gage for determining the position of the Work with relation to the cutters and with means for relatively moving the cutters and gage. The means for .relatively moving the cutters and gage have either been actuated directly by the oper ator or have been controlled by the operator, so that the contour of the sole and the outline of the channel has depended upon the skill and care of the operator in relatively actuating the gage and cutters or in throwing the means for relatively actuating the gage and cutters into and out of operation during the feeding of the shoe.

One of the objects of my invention is to produce a machine for rounding or channeling a shoe sole or for performing both of these operations which will act automatically to round or trim the sole to a predetermined contour or to out in the solo a channel of a predetermined outline.

XVith this object in view my invention consists in providing a solo rounding or channeling machine with connected mechanism arranged to not a tomatically to feed the shoe and to move the shoe at prede ternuncd times durin the feeding operation to vary the distance of the cut from the inseam or the juncture of the uppeififiith the Welt or sole.

In sole rounding and channeling machines Which have been provided with means for relatively moving the gage and cutter to vary the distance of the out from the inseam or the juncture of the upper with the welt or sole, the means for feeding the work consists of devices, such as feed wheels or clamps which engage the sole of the shoe being operated upon While held in position against the gage and cutter. by the operator. In the operation of the machines the feeding devices are liable to slip on account of the resistance of the cutters or on account of the holding-back or pushing ahead of the shoe by the operator. In machines providedvvith mechanism under the control of the operator for automaticallv moving the gage or cutter, this slipping of the feeding devices on the shoe acts to change the timed relation of the shoe and the mechanism for moving the gage or cutter so thatthe eontour or outline of the cut produced by the cutter is varied.

In order to avoid any slipping action of the feeding mechanism with a consequent change in the timed relation between the shoe and the means for relatively actuating the shoe and cutter to vary the distance of the cut from the inseam or the juncture of the upper with the sole or welt, a feature of my invention consists in providing a jack for supporting a shoe in position to be acted upon by the cutter and means for actuating the jack to feed the shoe, said mechanism for actuating the jack to feed the shoe being; connected with mechanism for moving th shoe to vary the distance of the cut from the inseam. In this connection it is to be noted that this feature of my in vcntion is equallv applicable to a machine in which automatic means under the control of the operator are provided for moving the shoe to vary the distance of the cut from the inseam, and to a machine in which such utomatic rue-ms are not under the control of the operator but act to move the shoe at predetermined times during the feeding operation.

Patented Nov. 24, 1914.

In different sizes and styles of shoes the contour of the sole or the outline of the channel or both vary considerably, and in order to provide for varying the contour or outline of the cuts produced by the rounding and channeling cutters, a feature of my invention contemplates providing a plurality of means for relatively moving the shoe and cutters for varying the contour of the sole or the outline of the channel or both for shoes of different sizes or styles.

Other features of my invention consist in certain devices and combinations of devices, in a sole rounding or channeling machine, hereinafter described and claimed, the advantages of which will be obvious to those skilled in the art.

In the drawings accompanying this application, I have illustrated my invention as embodied in an automatic rounding and channeling machine which is adapted to round and trim the edge of the sole and to cut a channel in the bottom of the sole. The machine is designed to trim the heel portion of the sole as well as the forepart and is provided with means for throwing the channeling cutter out of operation while the heel portion of the sole is being trimmed. The rounding cutter is mounted upon a fixed portion of the machine frame and the shoe is moved toward and from the cutter at right angles to the line of feed to vary the distance of the cut from the inseam or the juncture of the upper with the Welt or sole. The channeling cutter is mounted so as to be movable transversely to the line of feed so that the outline of the channel produced by the channeling cutter is varied both by the movement of the shoe transversely to the line of feed and also by the movement of the cutter. The shoe is supported upon a jack which may be of any suitable form adapted tosupport a shoe. and present the sole of the shoe to the rounding and channeling cutters, the form of jack shown being adapted to support an ordinary Wooden last. The jack is mounted so as to be movable to feed the shoe to the cutters and is movable toward and from the cutters transversely to the line of feed. The means for moving the shoe transversely to the line of feed to vary the distance of the cuts produced by the cutters from the inseam is arranged to act upon the jack so that the contour of the sole and the outline of the channel is determined independently of the shape of the last. Means are provided for actuating the jackto feed the shoe, which means and channeling cutters is predetermined an always the same for a given adjustment of the machine. Means are provided for moving the channeling cutter transversely to the line of feed to cause the cutter to cut at a greater distance from the edge of the sole at the shank than at the forcpart. In order to prevent the channeling cutter from producing a deeper cut in the rounded shank portion of the sole. the channeling cutter is mounted so as to have an oscillating movement when moved transversely to the line of feed so that the inner end of the cutter is raisednnd the depth of the cut maintained substantially constant. To provide for different sizes and styles a plurality of means are provided for actuating the jack to move the shoe transversely to the line of feed and for actuating the channeling cutter, any one of which means can be rendered operative by the operator. The means for so actuating the jack and channeling cutter are connected so as to be rendered operative simultancously. The specific means shown in the drawings consists of a iilurality of series of cams for actuating the jack and a single series of rams for actuating the channeling cutter, each cam of the series for actuating the channeling cutter corresponding to a cam in each of the series for actuating the jack, and the cams being so connected that the adjustment of the plurality of series of cams to bring any cam into operative position simultaneously brings the correspondi ng cam of the series for actuating the channeling cutter into operative position. The jack is movable away from the cutter to a position to allow the removal of a shoe which has been operated upon from the jack and the placing of another shoe thereon, and in order to render the machine more completely automatic in its action, means are provided whereby the movement of the jack toward the cutters after a shoe has been placed thereon throws the machine into operation, and means are also provided for automatically throwing the machine out of operation after the sole of the shoe has been trimmed and channeled.

Having thus indicated the main features of the machine illustrated in the drawings, I will now proceed to describe the specific construction thereof.

Referring to the drawings, Figure 1 is a view in side elevation of the machine, one side of the frame being removed; Fig. 2 is a sectional plan view on the line 22 of Fig. 1; Fig. 3 is a detail plan view on the line 3-3 of Fig, 1 illustrating the mechanism are connected with themeans for moving j for adjusting the machine for operation the jack transversely to the line of feed so.

1 indicates the rounding cutter herein shown as a rotary trimming cutter provided with cutting edges adapted to trim the edge of the sole and. also to bevel the outer edge of the welt or the upper edge of the sole. This cutter is splined upon a vertical shaft 2 mounted in hearings in the overhanging head of the machine frame, the splined con-L nection between the cutter and the shaft causing the cutter to rotate with the shaft and at the same time permitting it to move longitudinally of the shaft. To the upper end of the shaft 2 is secured a pulley 5 over which a driving belt 6 passes by means of which the shaft 2 and the cutter are rotated. The hub of the cutter 1 is extended downwardly and at its lower end is provided with a projecting flange 7 between which and the cutter is located a plate 8 which surrounds the hub of the cutter and the forward edge of which projects beyond the cutter and is shaped to enter the crease between the upper and the welt or sole. The plate 8 extends rearlvardly on both sides of a sleeve 9 mounted to slide upon a vertical stud 10 proj ecting downwardly from the head of the machine.

slotted to receive an adjusting bolt 12 which screws into the sleeve 9, and serves as a means for adjusting the plate 3 to cause its front edge to project a'greater or less distance beyond the otton The plate 8 constitutes crease gage which follows the crease between the upper and welt or sole as the shoe is fed past the cutter and moves the cutter up and down on the shaft 2 to nuiiiitain it in position to properly trim the edge of the sole. The downward movement of the plate 8 and of the cutter 1 is limite by so adjustabfe stop 3 secured to the stud I below the sleeve 9 by means of a set screw l. V

The channeling cutter is indicated at 13 A portion of the plate 8 is bent downwardly as at 11 and this portion is and as shown is of the ordinary drag-knife type. The shank of this cutter is secured to the lower end of a bar 14 mounted to slide vertically in a hearing at one end of a rock shaft 15 (see more particularly Figs. 5 and 9). The rock shaft 15 is journaled in a bushing 16 adjustably secured in a vertical slot 17 in an arm or bracket 18 provided with a horizontal supporting stem which is received in an opening in the head of the machine frame and secured therein so as to allow the arm or bracket 18 to be adjusted in a horizontal direction by means of a nut 19 engaging a screw-threaded portion of the stem. The bushing 16 is provided at one end with 'a circular flange which bears against the face of the bracket 18 on each side of the slot '17. From the other end of the bushing a screw-threaded sleeve 19 pro- The hub of a laterally projecting ,5 arm 20 loosely surrounds the sleeve 19" and is provided with a portion which projects into the slot 17. A nut 21 having a screwthreaded engagement with the sleeve 19 serves to lock the arm 20 and the bushing 16 Withits screw-threaded sleeve 19 in position in the slot 17. The rock shaft 15 projects beyond the end of the sleeve 19" and to this projecting end of the rock shaft is secured an arm 22 which extends in the same 5 direction as the arm 20. The free end of the arm 20 is curved to extend into a position above the arm 22. A screw-threaded rod 23 is adjustably secured to the free end of the arm 20 and passes through the arm 22. The lower endof the rod 23 is provided with adjusting nuts 24 and between these-adjusting nuts and the arm 22 is interposed a coiled spring 25 which acts to raise the arm 22, the upward movement of the arm being limited by a stop nut 23* on the riid 23.

By means of the construction above described it will be seen that amovement of the melt shaft 15will move the channeling o cutter 13 transversely tothe' lin'e'of feed in the arc of a -circle, the center of which is theshaft 15, and that the rock shaft can be adjusted horizontally to changetheinitial position of the "channeling cutter to cause 5 it to cut at a greater or less dlStfiIlCBfIOIIl the edge of the sole and can be adjusted vertically to changethe radius of oscillation of the cutter, and that neither of these adjustments disturbs the relative positions of 1 0 the arms 320 andQfl.

In the machine shown the channeling cutter 13 is moved transversely to the line of feed to cause the cutter to cut a greater distance from the edge of the sole at the shank ortion of the sole than at the forepart.. ihe shank portion of the'sole of a shoe is more rounded transversely to the shoe than the forepart and the object of mounting the channelingcutter so as to have an oscil- 1 0 latiug movement instead of a movement in a right line is to pre ent the channeling cutter from cutting a. dce ier channehat this portion of the sole when moved transversely to the line of feed. the oscillating movement of the cutter acting to raise the inner end of the (litter and cause it to assume substantially the same position with relation to the surface of the sole as when. acting on the forcpart o? the shoe.

The spring normally holds the cutter in the position shown in'Fig. 5. For moving the cutter transversely to the line of feed, the l'ollovv'ing mechanism is provided: (see more particularly Figs. 1 and 5.)- A lever '36 is pivoted to the upper portion of the head or" the machine frame and to the front end of this lever is pivoted a rod 27 which extends downwardly through a slot in the free end of the arm To the lower end of the rod E27 is adjustably secured a collar 28 which is arranged to contact with the free end of the arm 22 and depress the arm against the tension of spring when the rod 27 is lowered. This movement of the arm 3'2 oscillates the shaft 15 and through the hearing at the end of the shaft for the rod to which the channelingcutter secured moves the channeling cutter transversel to the line of feed. he rear end of the lever 2 is connected by means of link LE5! to one end of the lever 30. the other end of which extends into the path of movement of a series of" cams upon the lower surface of a cam dish Ell mounted to rotate with a vertical shaft 352 journalcd in the rear portion of the machine frame. The cams on the disk 31 are so timed with relation to the mechanism for feeding the shoe as to cause the channeling cutter to be moved at the proper times during the op oration of the machine as will be hereinaitcr described.

The rod 14 to which the channeling cutter 13 is secured is mounted to slide freely in a hearing at the end of the shaft 15 as ,has been de cribed. In. order to maintain the channeling cutter in a. position to cut a, channel of the desired depth in the sole, the rod l-l is supported by means of a presser foot which is arranged to bear against the sole. This presser foot as shown comprises an arm 33 secured to the lower end of a rod 34 and a roller 330 journaled in the lower end of the rod. The rod 34 is mounted in a vertical bearing formed in the front portion of the bracket 18. In order to hold the presser foot in contact with the sole a weighted lever 35 is provided pivoted to an upwardly extending portion of the bracket 18 and resting against a roll 'ournaled in the upper end of the rod 34. o the lower end of the rod 34 above the bearing for the roll 33 is adjustably secured, by means of nuts 36engaging a screw-threaded portion pivoted upon'a standard risin of the rod, an arm 37, the free end of which is provided with a stud or roller 38 which engages a slot 39 in the side of the lower end of the rod 14 to which the channeling cutter is secured. By this construction the channeling cutter is supported by the presser foot and rises and falls therewith so that the channel produced by the cutter is of uniform depth at all portions of the sole. By adjusting the arm 37 on the rod 34 the depth of the channel can be varied. The pin and slot connection between the rod 14 and the arm 37 allows the channeling cutter to be moved transversely to the line of feed as hereinbefore described.

As has been stated, the machine shown in the drawings is designed to trim the hcel portion of the sole as well as the forepart and is accordingly provided with means for throwing the channeling cutter out of operation while the heel portion of the sole is being trimmed. These means consist of means for raising the presser foot out of contact with thr sole, this movement of the prcsscr foot through the connection above described operating to also raise the channeling cutter above the surface of the sole.

For raising the resser foot a sleeve 40 is provided which loosely surrounds the rod 34 above the bearing for the rod and which is adapted to be clutched to the rod by means of a hall 41 located in a recess in the sleeve and arranged to bear against the rod. hen the sleeve 40 is in its lowest position it rests upon the bearingfor the rod 34 and a projection from the bearing engages the ball and holds it in a osition to allow the rod 33; to move freely t rough the sleeve. When the sleeve is raised, however, the ball 41 becomes wedged between the rod and the side of the recess and the rod is connected to the sleeve so as to be raised thereby. This construction allows the resser foot to rise and Fall as the shoe is fed and to be raised positively whenever the sleeve 40 is raised. A stud 42 projecting laterally from the sleeve 40 is engaged by the slotted forward end of a lever 43 pivoted upon the head of the machine, the rear 'end of which lever is connected by means of a rod 44 to a lever 45 from the base plate of the machine. T e lever 45 rests upon a cam 46 formed upon the upper surface of a worm wheel 47 journaled in the lower rear portion of the machine frame. This worm wheel is actuated in timed relation to the mechanism for feeding the shoe to cause he presser foot and the channeling cutter suivported thereby to be raised at the proper times during the feeding operation, as will. be hereinafter described.

The 'ack shown in the drawings is constructe to support an ordinary wooden last and comprises a heel post 48 and a toe post 49 mounted upon the base 50. The toe post 49 is supported upon a screwthreaded stud 51 and rests upon the hub' of an adjusting wheel 52 having a screw-threaded engagement with the stud 51. A block 53 is mounted in segmental guideways in the upper end of the post -19 so to oscillate in a. direction transverse to the shoe supported. upon the jack and the toe support 51 is mounted in segmental guideways in the block 53 so as to oscillate in a direction longitudinally of the shoe, the construction. being such that the toe support accommodates itself to the toe portion of the lasted shoe. A heel pin 55 for entering the hole in the heel portion of the last is pivoted tothe upper end of the heel post 18 and is provided with a downwardly extending arm through which the operating screw 56 passes, by means of which the heel pin is tipped to force the toe portion of the lasted shoe firmly against the toe support. The heel and toe supports l8 and 49 are adjustable toward and from each other to accomm )date lasts of different sizes. The means for adjusting the posts consists of a shaft 57 mounted in the base 50 and extendinglongitudinally thereof, said shaft being provided with right and left screwthreaded portions which engage blocks 59 and 60 mounted in a slot formed in the upper" portion of the base 50, by which blocks the

posts

48 and 49 are carried. Headed screws 61 project from the sides of the

blocks

59 and 60 through slots in the side of the base 50 and serve to guide the blocks-and retain them in position.

In order to allow the lasted shoe to be tipped to bring that portion of the sole be ing acted upon by the cutters more neurlv into a horizontal plane, provision is made whereby the jack can be tipped in a. direction transverse to the shoe supported thereon and also longitudinally of the shoe. To allow the jack to be so moved the base 50 is movably mounted in segmental guideways in a slide (32 so as to move in a direction lon gitudinally of the shoe supported upon the jack, and the slide 62 is mounted in mental guideways upon a carrier (73 so as to move in a direction transversely of the shoe. The segmental guideways for the base 50 and for the slide 62 are curved in the arcs of circles the centers of which are coincident or substantially so with the central longitudinal and transverse axes of the sole of the shoe. By this construction, longitudinal and transverse tipping movements imparted to the shoe during the sole trimming and channeling operations do not move the sole of the shoe toward or from the cutters, so as to vary the contour of the sole or the outline of the channel which will be the same whether the shoe is tipped or not. For limiting the longitudinal tipping movements adjustable stop-pins til screwing into the carrier 63 and projecting upwardly under the base plate 50 are provided, and for limiting the transverse tipping movements adjustable stoppins 5 screwing into the ends of the slide 52 are provided (see more particularly Fig. 14), which are arranged to contact with the upwardly extending flange 66 at the edge. of the carrier 63.

The carrier (33 is mounted in guideways in the upper end of a sleeve 67 rotatably mounted upon the upper end of a rod 68, the lower end of which is secured in a yoke 69 secured to a shaft 70 journaled in the lowenfront portion of the machine frame. An arm Tl is secured to the shaft 70 and extends rearwardly and is provided with a weight 72 which tends to rock the shaft 70 in a direction to move the shoe-supporting jack toward the cutters.

In order to actuate the jack to feed the shoe, the carrier 63 is moved longitudinally in the guideways in the upper end of the sleeve 67 and the sleeve 67 is rotated, by the following mechanism :-The edge of the carrier 63 is provided with rack-teeth and with the rack-teeth a to engage, bearing flanges being provided below the raclcteeth and below the teeth of the pinion. The pinion T3 secured to the upper end of a shaft H, the lower end of which is journaled in a yoke 75 mounted upon theshaft 70, and the upper end of which below the pinion 73 is journaled in a bearing block 76. The shaft 7i extends through a guiding slot in an arm or block 77 secured to the rod 68 and the upper end of the shaft is pressed in a direction to maintain the pinion T3 in mesh with the teeth of the rack on the carrier 63 by means of a leaf-spring 78 secured to block 77 and pressing against the bearing block 76. The bearing block 76 is mounted in a slot in the projecting end of a slide 79 mounted to slide in a bushing 80 secured in a cross-bar or bracket of the machine frame, the movement of the shoe 111 both directions being limited by means of a stop-pin 81 securedto the slide and projecting through a slot in the bushing. It will be seen that by means of the above-described construction the pinion 73 is held in mesh with the rack of carrier 63 and moves in and out withthe carrier as the jack moves toward and from the cutters during the rounding and channeling operation. A slot 82 is formed in the. lower surface of the carrier 63 and extends longitudinally thereof. At each end of the slot is an adjustable block 83 secured to the carrier, and rejected into the slot from the upper end of the sleeve 6': is a stud 84 upon which is rotatably mounted a rectangular block 85. The pinion 73 rotates continuously in the same direction during the operation of the machine, and during such rotation it causes the carrier 63 to travel in the guideways in the upper 'iinion' 73 is arran ed b pivotally end of the sleeve 67 until one of the blocks 83 contacts with the block 85 when the continued rotation of the pinion causes the carrier and sleeve 67 to be rotated upon the rod 68 through half a revolution. After the carrier has been rotated through half a revolution it is again caused to travel in the guideways in the upper end of the sleeve 67 until the other block 83 contacts with the block 85 when it is again turned through half a revolution.

During the feeding movement the jack is pressed toward the cutters by means of the weighted arm 71 as has been described. For controlling the position ofthe jack or of the shoe supported thereon, the machine shown in the drawings is provided with two devices or sets of devices, one of which is arranged to control the position of the shoe with relation to the cutters during the heel trimming operation, and the other of which is arranged to control the position of the shoe during the trimming of the forepart and the cutting of the channel. The first of these devices is arranged to act upon the shoe and consists of a last or heel seat gage against which the shoe is pressed by the action of the weighted arm 71, and the other device consists of means for actuating or guiding the jack. The contour of the heel portion of the sole is therefore determined by the shape of the last while the contour of the forepart is determined solely by the movements of the device or devices for actuating or uiding the jack and is inde pendent of tie shape of the last.

The last or heel seat gage is indicated at 86 and is carried at the outer end of an arm 87 pivotally connected to a slide 88 mounted in a bracket in the upper portion: of the machine frame. For maintaining the gage in position to properly engage the shoe the arm 87 is provided with a slot through which passes a pin 89 adjustably secured in a vertical slot in a downwardly extending portion of the plate 8 (see Figs. 5 and 9). %y this construction the gage S6 rises and falls with the crease-guide and with the rounding cutter 1 and can be adjusted to engage the shoe at the desired distance below the crease between the upper and sole. As has been stated the gage 86 is utilized to control the position of the shoe only during the heel trimming operation, and in order to throw the gage out of operation during the into the position to allow the slide 88 to be moved rcarwardly and said rod is arranged to be actuated by one of a series of cams on the cam-disk 31. A spring 92 acts upon the slide 88 and holds the gage 86 in contact 7 with the shoe while the slide 88 .is unlocked.

The means for actuating or guiding the jack to control the position of the shoe during the trimming of the forepart of the sole and the cutting of the channel comprises @;5 a plurality of series of cams 92 and intermediate connections between the cams and the bearing block 7 Gfor the shaft 74. Each series of cams is arranged on the circumference of a disk and the several disks are con- 30 nected to or extend from a common hub mounted to rotate with the shaft 32. The cams of each series correspond to the different lengths of the shoes to be operated upon and the different series correspond to35 the diflerent styles. Separate cams corresponding to the differences in width of a shoe of a given size is rendered unnecessary by the adjusting means of the connection; between the cams and the bearing block 76 90- as will be described. I

The connections between the cams 92 and the block 76 consist of a slide 93 mounted above the bushing 80 and conveniently made in two parts secured together by the screw 95 94. Mounted in this slide is a spring-pressed plunger 95 which bears a ainst the block 76. A bullclutch 96 is provi ed for locking the plunger 95 to the slide 93. The ball-clutch 96 is actuated to release the plunger 95 to we allow it to move freely in the slide 93 while the heel portion of the sole is being trimmed, by means of a spring-pressed slide 97 mounted in the slide 93 and extending into the path of movement of one of a series of cams 98 arranged upon the upper surfaces of the disks carrying the cams 92. By this construction the plunger95 is held in contact with the block 76 during the heel-trimming operation and automatically accommodates itself to the varying positions of the block due to the movement of the jack controlled by the gage 86. It will be evident that the position of the block 76 will vary with the width of the shoe and that the position of 116 the plunger 95 with relation to the slide 93 will correspondingly vary; The plunger 95 will thus be in proper position to be clutched to the slide 93 when the shank portion of the sole reaches the trimming $61, 120

remainder of the trimming o oration, means- .at which point the slide 97 is relea are provided for locking t e slide 88 to hold the gage 8G rigidly in position and for unlocking the slide to allow the gage to ield when the shoe is brought into contact/t erewith. These means consists of a ball 90 which is arranged to clutch the slide 88 to its guideway and to. Jrevent the rearward movement of the sli e. A rod 91 .is arrangedto engage the ball 90 and to move it the cam 98 to allow the ball-clutch to operate. As the connections between the cunt and the jack thus automatically accommodate themselves to variations in the width of 1:5 shoes, the same cam can be used to actuate the jack for difl'erent widths'bf the same size of shoe.

In order to allow the'cams 92 to be adiusted to bring any cm into operative rule-' tion with the slide 93 and to allow the-camdisk 31 to be adjusted to bring any one of the cams carried thereby into operative relation with the lever 30, the hub of thedisks which carry the cams 92 is splined upon a sleeve 99 and the cam-disk 31 is rigidly secured to the sleeve 99. To the lower end of the sleeve 99 is secured a plate 100 which is clutched to a gear wheel 101 secured to the shaft 32 by means of pins 102 projecting upwardly from the face of the gear-wheel through openings in the plate 100. This construction allows the hub to which the disks which carry the cams 92 are secured to be moved longitudinally of the sleeve 99 to bring any one of the series of cams opposite the slide 93, and the sleeve 99 tobe raised and rotated on the shaft 32 to bring" any cam of the series which has been brought opposite the slide 93 into operative relation thereto, and any one of the cams of the disk 31 into operative relation to the lever 30. The hub to which the disks which carry the cams 92 are secured is supported by the forked end of a lever 103 pivotedto the frame of the machine, whereby a move ment of the lever upon its fulcrum raises or lowers the hub. F or looking the lever in position, a pin is provided which may be inserted through one of a series of holes 104 in the frame in a position to contact with a lug on the lever. For raising the sleeve 99 to disconnect the sleeve from the shaft 32 and for rotating the sleeve the following mechanism is provided :-A lever 105 is pivoted upon a shaft 106 in the lower portion of the machine frame and is provided at one end with a foot treadle and at the other end is pivotally connected with-a yoke 10?, the upwardly extending arms of which are pivotally connected to and support a plate or frame 108. The plate 108 is provided with a guiding bearing through which a shaft 109, to be hereinafter referred to, passes, and with an extension which engages a grooved collar 110 fast on the sleeve 99.

This construction is such that the depression of the treadle raises the yoke 107 and through the plate 108 raises the sleeve 99 to disconnect the plate 100 from the gear 101. A shaft 111 provided with a knob 112 at one end by means of which it can be turned by the operator is journaled in the plate 108 and has secured thereto a beveled gear 113 which meshes with a beveled gear 111 secured to the lower end of the sleeve 99. After the sleeve 99 has been raised as-. above described, a rotation of the shaft 111' by means of the knob 112 rotates the sleeve 99 and the cam-disk 31, and through the splined connection of the sleeve with the 'hub to which the disks which carry the cams 92 are connected also rotates the cams 92. The plate 100 is provided with a series of holes to receive the pins 102 so that the sleeve 99 can be again connected to the shaft 32 when the desired cams have been brought into proper position.

The shaft 32 by'which the cam-disk 31 and the cams 92 are rotated, and the shaft 7 4 to which the pinion 7 3 which aetuates the jack to feed the shoe is secured, are driven from the driving shaft of the machine throu h mechanism which may be descri ed as folTows:11-5 designates the main driving shaft constantly driven by means of a belt 116 passin over the driving-pulley 117 secured to the s aft. A worm 118 is loosely mounted upon the shaft and isarranged to be clutched thereto by mechanism to be hereinafter described. The Worm 118 meshes with a worm gear 119 secured. to a short horizontal shaft 120 journaled in the lower portion of the machine frame beneath and at right angles to the driving shaft. A worm 121 is secured to the forward end of this shaft and meshes with a worm gear 122 loosely mounted upon the shaft 70, the gear 122 in turn meshing with a worm gear 123 upon the shaft 74. A beveled gear 124 is secured to the rear end of. the shaft 120 and is arranged to be engaged by either of two oppositely disposed beveled

gears

125 and 126 mounted to rotate with the vertical shaft 109. To this shaft 109 Is: secured a pinion 127 which meshes with the gear 101.

From the above description, it will be seen that the mechanism for actuating the jack to feed the shoe and for relatively ac tuating the jack and cutters to rary the distance of the cuts from the inseam or the juncture of the upper with the Welt or sole are connected so that one mechanisn'i is operated in timed relation to the other, and thus a relative movement of the shoe and cutters is produced at predetermined times during the feeding operation. The mechanisms are so timed that the shaft 32 is revolved through one quarter of a revolution while the jack is being actuated to transfer the point of operation of the rounding out-- ter completely around the sole of the shoe supported on the jack, there being in the machine shown in the drawing four cams 92 for actuating the jack in each of the series, and four cams carried by the disk 31 for actuating the channeling cutter. The same cams are utilized for roundin and channel ing right and left shoes of t e same style and size, it being merely necessary to reverse the direction of movement of the "cams. This reversal of movement is rovided for by the oppositely disposed er" eled gears 125 and 126 which are mounted upon a common hub splined upon the shaft 109. For moving the gears longitudinally of the shaft 109 to disconnect one gear from the gear 124 and bring the other gear into enga ement therewith, an arm 128 is secure to the shaft 109 and extends beneath the hub of the gear. A treadle lever 129 is secured to the shaft 106 by means of which the shaft can be rocked to raise the arm 128.

T he mechanism for driving the

shafts

32 and 74 are automatically thrown into and out of operation by means of a controlling mechanism which acts to connect the worm 118 with the driving shaft and to disconnectit therefrom. This mechanism consists of the worm wheel 47 hereinafter referred to, mounted to re olve in a horizontal )lane in the lower portion of the machine rame and meshing with a. worm 131 loosely mounted upon the driving shaft 115. This worm is connected to the driving shaft through mechanism operated by the movement of the jack toward the cutters after a shoe has been placed upon the jack, and is automatically disconnected from the driving shaft after the rounding and channeli'ng operations have been completed as will be described. A cam groove 130 is formed inthe lower v surface of the Worm-wheel 47 which receives a roll or stud at the end of an arm 231 secured to a short vertical shaft 132 mounted in a bracket extending up wardly from the base of the machine frame. To the shaft 132 is also secured a short arm 133 which is pivotally connected to a collar seated in a groove in the clutchcollar 131 splined to the shaft 115. The cam groove 130 is so shaped that the clutch-collar 135i is moved longitudinally of the shaft 115 into engagement with the clutch projections at the end of the worm 118 and is held in such position during the greater portion of the revolution of the worm-gear l7. During the latter part of the revolution of the worm-gear the clutch collar 131 is moved to disconnect the worm 118 from the driving shaft to throw the mechanisms for actuat ing the

shafts

71 and 32 out of operation. The mechanisms for actuating the shoe and cutters to vary the distance of the cuts from the shoe upper are thus controlled by the worm-gear 47 and are thrown into and out of operation at certain points in the revolution of the gear.

It is desirable that means be )rovided for preventing any movement of hose mechanisms while the worm 118 is disconnected from the driving shaft and while the worm gear 17 is at rest as any such movement of these mechanisms would change the timed re ation between the mechanisms and the worm-gear. Means are accordingly provided for locking the worm 118 in position while it is disconnected from the driving shaft. These means consist of an arm 1.35 secured to a rock-shaft 136 journaled in the lower portion of the machine frame at one side of and slightly below the driving shaft. the end of which arm'is provided with a slot which is adapted to engage a pin 137 projecting radially from the Worm. A lever 138 is also secured to the shaft 136, one end of which is acted upon by a coiled spring 139 which tends to rocl; the shaft 136 in a direction to bring the slot in the arm 135 into engagement with the pin 137, and the other end of which rests upon a cam surface 110 formed on the upper surface of the Worm gear 47. The cam surface 110 is shaped to actuate the lever 138 to rock the shaft 136 in a direction to remove the slot in the arm 135 from engagement with the pin 137 before the worm is connected to the driving shaft, and to hold the arm 135 out of the path of movement of the pin 137 until the worm is again disconnected from the driving shaft. W' hen the worm is disconnected from the driving shaft, the cam surface 140 allows the shaft 136 to be actuated by the spring 135) to bring the slot in the arm 135 into engagement with the pin 137.

As has been stated the worm 131 is con? nected to the driving shaft through mechanism operated by the movement of the jack toward the cutters after a shoe has been placed upon the jacl; and is automatically disconnected therefrom after the rounding and channeling operations have been completed. For accomplishing these results, a shaft 111 is journaled in the machine frame at one side of and slightly above the driving shaft 115, being so mounted that it can be rocked and moved longitudinally. Loosely pivoted upon the shaft 1-11 between two collars fixed to the shaft is an arm 112 which is connected to a collar seated in a groove in a clutch-collar 143 splined on the shaft 115. and serving to connect the Worm 131 to the driving shaft. An arm 144 is splined upon the shaft 141 so as to rock with the shaft and be capable of movement longitudinally of the shaft and is acted upon by a coiled spring 145 surrounding the shaft and interposed between the hub of the arm and one of the collars between which the arm 141is mounted. The movement of the arm 11 1 longitudinally of the shaft under the influence of the spring 145 is limited by a collar fixed on the shaft. The outer end of the arm 144. is weighted and the downward movement of the arm is limited by an adjustable step 116. A vertically extending arm 147 is also splined upon the shaft 141 so as to rock with the shaft and to be capable of moving longitudinally thereon. A coiled spring 148 surrounding the shaft 14-1 and interposed between the arm 14-? and a fixed. collar on the shaft 1-11 tends to press the arm 147 against a collar fixed to the shaft at the outer side of the arm. A ball-clutch 149 is provided for locking the arm 147 to the shaft 141 and means for actuating the clutch to release the arm are also provided consisting of a slide 150 mounted in the hub of the arm and connected by a link 151 to a lever 152 pivoted upon the hub of the arm 144. A spring coiled about the pivot of the lever 152 and having its ends connected to the lever 152 and-- to the hub of the arm 144 tends to move the slide 150 in a direction to allow the clutch 149 to connect the arm 147 to the. shaft 1-11. The upper end of the arm 147 bears against the side of a slide 153 (see Figs. 1 and 4), one end of which is forked and pivotally connected to a collar loosely mounted on the shaft 74 between two fixed collars and the other end of which is slotted and extends on each side of the shaft 109 between two collars secured to the shaft, the construction being such that the slotted end of the slide is supported and guided by the shaft and collars. The side of the slide 153 against which the arm 147 bears is provided with a recess 154 and at the rear of the recess with a projection 155. A pin 156 (see Figs. 1 and 2) projects from the upper surface of the worm-gear 47 into a position to engage the lever 152 and the arm 144 during the rotation of the gear.

The operation of the mechanism for connecting the worm 131 to the driving shaft 115 and to disconnect it therefrom is as follows :-Starting with the parts in the position shown in Figs. 1, 2, and 4, which is the position which the parts assume during the operation of the machine, the clutchcollar 143 being in engagement with the clutch projections at the end of the worm 131 and the arm 147 being clutched to the shaft 141, the worm gear 47 rotates in the direction indicated by the arrow until the pin 156 contacts with the lever 152. The continued rotation of the worm-gear swings the lever 152 on its pivot and moves the slide 150 to disconnect the arm 147 from the shaft 141;. After the arm 147 is disconnected from the shaft 141 the pin 156 contacts with the arm 144 and through the spring 145 moves the shaft 141 to disengage the clutch-sleeve 143 from the worm 131..

The longitudinal movement of the shaft 141 compresses the spring 148 and the action of the pin on the arm 144 moves the arm longitudinally of the shaft to compress the spring 145. The machine having been thus brought to rest, the jack is moved away from the cutters to allow the removal of the shoe which has been operated upon and the placing of another shoe on the jack. During the outward movement of the jack the slide 153 is moved to bring the recess 154 opposite the arm 147which is moved longitudinally of the shaft 141 into the recess by the spring 148. -During the last portion of the outward movement of the jack the .proiection 155 engaging the arm 147 swings the arm and thereby rocks the shaft 141 to raise the aim 144 and lever 152 out of engagement with the pin 156. As

soon as the lever 152 is released from the pin it is moved by its spring in a direction to move the slide 150 to allow the clutch 149 to lock the arm 147 to theshaft 141, and as soon as the arm 144 is released from the pin the spring 115 moves the arm longitudinally of the shaft so that when the arm again descends it strikes behind or upon the in. During the inward movement of the Jack to bring the shoe which has been placed upon the jack into position to be operated upon by the cutters, the arm 147 is forced out of the recess 154 of the slide 153 and the shaft 141 is thereby moved in a direction to bring the clutch-collar 143 into engagement with the worm 131.

It is desirable that means be provided for locking" the worm-gear 47 and the worm 131 from movement while the clutch-collar 143 is disconnected from the worm and to accomplish this result an arm 157 is loosely mounted upon the shaft 141 between two collars fixed to the shaft and rests at its free end upon the extended end of the worm A slot or notch is formed in the side of the arm 157 which is arranged to engage a pin 158 extending radially from the worm. \Vhen the shaft 141 is moved in a direction to disengage the clutch-collar 143 from the worm 181 the arm 157 is moved to bring its slot into engagement with the pin 158 and thereby lock the worm 131 and the gear 47 from movement.

The operation of the machine, above described, may be briefly described as follows:In the machine shown in the drawings the center of the heel portion of the sole is presented to the cutters when the machine is first thrown into operation. At this time the heel seat or last gage 86 is l cked in position and the plunger is free t3 move with relation to the slide 93. A shoe having been placed upon the jack and the cam-disk 31 and the cams 92 having been adjusted to bring the cams corresponding to the style and size of the shoe into operative position, the jack is moved toward the cutters to bring the sole of the shoe into a position to be operated upon by the trimming cutter, the presser foot and the channeling cutter at this time being raised above the surface of the sole. This movement of the jack connects the worm 131 to the driving shaft 115 as has been described. During the first portion of the rotation of the Wormgear 47 the worm 118 is unlocked and connected to the driving shaft 115. The heel seat or last gage 86 remains locked in position and guides the shoe until the shank portion of the sole is brought opposite the rounding cutter. At this point in the feeding operation, the heel seat or last gage 86 is unlocked and the plunger 95 is to the slide 93: Also the presser foot and c anneling cutter are brought down into contact with the sole. During the continuation of the feeding operation, the shoe is moved transversely to the line of feed by the action of the cam 92 which is in operative relation to the slide. 93 to vary the distance of the cuts produced by the rounding and channeling cutters from the inseam'or the juncture of the upper with the welt or sole, until the shank portion at the other side of the sole has been trimmed. At this point in the feeding operation the gage 86. is again locked in position and the plunger 95 is unlocked from the slide 93, and during the trimmin of the remainder of the heel portion of t e sole the position of the shoe is controlled by the gage 86. At this point in the feeding operation also, the presser foot and the channeling cutter are raised out of contact with the sole. At predetermined times during the feedin operation the channelin cutter is move by the cam on the camisk 31 to cause the cutter to cut the channel at a greater distance from the edge of the sole at the shank portions than at t e forepart. At the end of the trimming operatlon the worm '118 is disconnected from the shaft 115 and locked in position by the action of the cams carried by the worm-gear 47 and the worm 131 is disconnected from the driving shaft and locked in position as has been described. During the operation of the machine, the jack may be tipped by the operator to bring the portion of the sole being operated upon into the desired plane andmay be rotated to maintain the edge of the last parallel to the line of feed. In operating upon most styles of shoes, however, it is unnecessary to maintain the edge of the last parallel to the line of feed. Also the pressure of the cutters and devices which act upon the soleand upon the upper near the sole acts to tip the jack automatically to bring the sole into the desired plane so that no intervention on the part of the operator is required during the trimming and channeling operations.

Having thus described my invention, I claim as new and desire to secure by Letters Patent of the United States.
