  • My device may be used to notable advantage in conjunction with a model or a sample shoe, constituting the primary pattern, to reproduce upon the periphery of a pattern blank or disk the niceties of contour which are formed by variations in the width of the sole edge, z'. e., that portion of the sole which projects and is visible beyond the upper of the shoe.
  • the pattern thus produced may then be employed ina ma-. chine of suitable'construction for trimming I or rounding soles previously attached to the uppers, preferably one of a type which I have invented for the special purpose, and
  • the contour-of the soley is an important factor in its appearance, it being of course parmachine, which is used to round soles al-4 readyattached, to secure the proper contour for the sole edge of a shoe having a sole edge of varying width byy imitation of a sample sole edge and this has been one of the mosty diiicult and responsible operations inthe manufacture of shoes.

  • the disk after having been thus patterned corresponds detail for detail with the sole edge or other model or primary pattern, and is ready for use in the sole rounding machine.
  • Another important object of my invention is to provide means to mark the pattern at points easily visible to the operator of the sole-rounding or other machine in which the pattern is to be used, so that the operator in setting the stops which control the operation of the rounding mechanism preparatory to use of the pattern can readily see by the mark upon the toe-shaping portion of the cam, where to set the stop which controls the operation of the rounder upon the toe of the shoe; and other salient features of the sole edge will be observed in marking the pattern, so that if the operator follows these indicia faithfully he can set the stops on his rounding machine with accuracy, insuring the rounding of the sole edges to correspond closely with that of the sample shoe.
  • Means to throw the rotary cutter out of operative position at will, and means to maintain it out of operative position, independently of the actuating mechanism, are also provided; and I have included also means to hold the cut-ter at a point of operation where it will shape automatically the inactive limb of the pattern, which term I will use hereinafter for the sake of brevity to designate that portion of the periphery of the pattern which is usually inoperative in the sole-rounding or other machine in which the pattern is used eventually.

  • This angular positioning of the generator arm may be regulated by any convenient and suitable means, manual or mechanical, and in Figs. 1 and 2 I have shown a follower and regulating device 17 of a character especially useful in copying the sole 1S of a shoe 19 whose upper 2O is presented by the operator for running ⁇ engagement with the nose o-f the follower.

  • the other member of the clutch (See Fig. 7) consists of a cap 52 having a head portion 53 provided with a pin 54 traversing a slot 55 in the shaft 31 and serving to communicate the motion of the shaft 31 to the cap, which in turn operates the worm sleeve through the medium of a pin 56 and socket 57 connection.
  • the cap 53 can be grasped manually and drawn outward axially toward the left to disengage the sockets from the pins, when the action of the brake 49, 50 will stop the rotation of the worm sleeve 35; but the cap cannot be withdrawn completely from the shaft without removal of the pin 54.
  • the disengagement of the clutch members will be effected before withorawal of the sample shoe from engagement with the abutment 26 and the follower 17, in order to avoid the undue cutting away of the periphery of the pattern, which would result normally under the action of the cutter 1 pressed thereagainst by the spring plunger 21.
  • the swing arm 4 may be moved outward againstthe action of the plunger 21 to swing the cutter away from the disk by any suitable means, and as one convenient form of such means I have shown (see Fig. 6) a bell crank lever 5S mounted pivotally at 59 upon the base of the machine, one arm 60 of the lever extending upward into position to engage a coperating depending arm 61 integral with the swing arm, while the other arm 62 of the bell crank extends outward beyond the frame of the machine and is provided with a connecting rod 63 extending downward to a treadle or other suitable operating device, (see Fig. 1). After the swing arm has been moved outwardly by this means, I prefer to utilize suitable means to hold it positively at its outer position of disengagement.

Normally this dog will be left in the upright position shown in Fig. 1, where it does not interfere with free swinging of the arm 4 toward the pattern blank disk, but when the dog 64 is moved down into a horizontal position by the operator, the dog will be engaged by the portion 67 of the arm 4 and the arm will be held outward away from the disk.

  • the belt 9 may now be set in motion, and after the portion 18 of the shoe sole has been placed in contact with the abutment 26 as illustrated in Figs. 1 and 2, the dog 64 is raised to permit the plunger 21 to swing the arm 4 around to bring the generator 1 into operative cutting engagement with the periphery of the disk 16, this being the position shown in Fig. 2, where the cutter has entered deeply into the disk and shaped the disk at that point in correspondence with the relatively wide edge of the sole at the portion 18. r[his deep cut is permitted by the relatively' large displacement of the follower 17 which has swung over into engagement with the upper at 20.
  • the abutment 26 is thus rotated to feed the sole edge 18-25-27 along from right to left, the narrowing width permitting the upper to crowd back the follower 17, and at the same time the pattern blank disk 16 is rotated by 'the shaft 38 in the direction of the arrow, at a much lower speed, in the instance illustrated, but at a proportionately constant ratio, so that the narrowing peripheral cut indicated by the broad dots in Fig. 2 corresponds exactly in contour with the varying width of the sole edge.
  • the operator should maint-ain the sole edge in true tangency with the rotary abutment at a point lying in a line passing from the axis of the rotary abutment through the midpoint 121 of the follower 17, and to assist the operator in accomplishing this I have shown a mark on the follower at the midpoint 121 and a corresponding mark 122 on the adjacent arm 24, these marks, when alined, indicating that the sole is properly positioned. After the portion 18-25-27 has traversed the follower, the opposite side of the sole edge is caused to traverse in like fashion, from the point 27 to the point 29 &c.
  • the pattern 16 may alternatively be left in place to serve as a master pattern, in which event a fresh pattern blank disk 85 (see Fig.
  • rl ⁇ he follower roll or disk 94 will be forced, by the action of the plunger 21, into engagement with the periphery of the master pattern 16 at all points, accompanied by similar cutting engagement of the generator 1 with the pattern blank disk 85, which will thus be shaped as an exact replica of the master pattern 16, and further replicas may be produced automatically without further attention to the machine than is involved in removing each replica as it is finished and substituting a fresh pattern blank disk.

g' UNTTED sTATEs PATENT oEEioE FREDERICK HENRY PERRY, OF BEVERLY, MASSACHUSETTS, ASSIGNOR TO UNITED SHOE MACHINERY COMPANY, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY.
Specification of Letters Patent.
Application filed February 12, 1908. Serial No, 415,567.
To all whom 25 may concern.'
Be it known that I, FREDERICK I-I. PERRY, a citizen of the United States, residing at Beverly, in the county of Essex and Commonwealth of Massachusetts, have invented certain Improvements in ll?atterri-Gener-l This invention relatesto mechanism forv generating patterns, and is of especial utilvity when employed in the production of patterns for sole rounding machines for use in the manufacture of boots and shoes, although I contemplate the use of my invention in any field to which itis adapted by the nature of my improvements.
My device may be used to notable advantage in conjunction with a model or a sample shoe, constituting the primary pattern, to reproduce upon the periphery of a pattern blank or disk the niceties of contour which are formed by variations in the width of the sole edge, z'. e., that portion of the sole which projects and is visible beyond the upper of the shoe. The pattern thus produced may then be employed ina ma-. chine of suitable'construction for trimming I or rounding soles previously attached to the uppers, preferably one of a type which I have invented for the special purpose, and
which is 5 disclosed in my co-pending applil cations for U. S. Letters Patent, Serial No.
559,332 iiled May-- 4,1910, and Serial No.. 679,765 renewed February 24, 1912, atype] of machine in which mechanism controlled l by the pattern acts to trim the soles of4 any desired number of shoes operated upon, to
form on their edges a counterpart of the model or of the peripheral contour of the sole edge of the sample shoe.` In most shoes the edge of the sole is of varying width and,
the contour-of the soley is an important factor in its appearance, it being of course parmachine, which is used to round soles al-4 readyattached, to secure the proper contour for the sole edge of a shoe having a sole edge of varying width byy imitation of a sample sole edge and this has been one of the mosty diiicult and responsible operations inthe manufacture of shoes.
Variations from the sample have been usual; `often the discrepancy has so marred the style as to diminish the value of the product; occasionally mated shoes have varied from each other so seriously that one or. both has required alteration, with result-k ant expensive loss of work, and not infrequently one Vor both of the pair is discarded with complete or` partial loss of material.
To eliminate .the personal factor is an important object of my invention, and as the varying projection of the sole edge furnishes the characteristic to be reproduced, I provide according to the preferred embodiment of my invention pattern-or model-copying mechanism, including a guide or abutment preferably rotary, to be engaged and traversed by the sole edge or other suitable model. and preferably actuated positively to feed the model at a speed having a constant ratio'to the speed or rotation of the disk to be patterned, until the entire length of the model surface Yhas traversed the feeder; 'and concurrently with this traverse of the sole edge, a follower member, also forming part of the copying mechanism, is maintained inv contact with the traveling surface of the'shoe upper adjacent the region of the sole edge contacting with the abutment or rotary feeder; the follower'projecting over the edgeyof the sole and beyond the edge of the abutment to an extent varying with the changing width of those por- Patented May 28,1912.
tions f. of the sole edge traversed, and` correswings therewith as a unitary relatively rigid structure about a pivot, to maintain the follower in operative contact with the primary pattern and to maintain the cutter in corresponding varying operative contact with the blank disk to be cut to pattern. The disk after having been thus patterned corresponds detail for detail with the sole edge or other model or primary pattern, and is ready for use in the sole rounding machine. It may be used also as a master pattern in the production of similar disks either by causing it to traverse the rotary abutment while another pattern disk is engaged operatively by the rotary cutter, or by arranging the master pattern disk coaXially with respect to the blank or disk to be cut to pattern, rotating them in unison, and arranging coaXially with the rotary cutter a follower disk or device which will engage the periphery of the master pattern disk and regulate the depth of cutting effected by the cutter, according to the varying radii of the rotating master pattern disk.
Another important object of my invention is to provide means to mark the pattern at points easily visible to the operator of the sole-rounding or other machine in which the pattern is to be used, so that the operator in setting the stops which control the operation of the rounding mechanism preparatory to use of the pattern can readily see by the mark upon the toe-shaping portion of the cam, where to set the stop which controls the operation of the rounder upon the toe of the shoe; and other salient features of the sole edge will be observed in marking the pattern, so that if the operator follows these indicia faithfully he can set the stops on his rounding machine with accuracy, insuring the rounding of the sole edges to correspond closely with that of the sample shoe.
Means to throw the rotary cutter out of operative position at will, and means to maintain it out of operative position, independently of the actuating mechanism, are also provided; and I have included also means to hold the cut-ter at a point of operation where it will shape automatically the inactive limb of the pattern, which term I will use hereinafter for the sake of brevity to designate that portion of the periphery of the pattern which is usually inoperative in the sole-rounding or other machine in which the pattern is used eventually. This limb will preferably be of uniform radius.
My invention contemplates also the simultaneous production of a plurality of patterns by the use of a cutter or other generator which will engage and shape at the same time a number of disks arranged coaxially. To facilitate this I have devised connectors applicable to adjacent disksand serving to couple them together for co-rotation with each other and with their actuating shaft.
Other objects of my invention comprise means preferably formed in connection with the pattern actuating shaft or other work support to enable the operator to locate each blank in proper position so that the generator will start work at a similar predetermined region of each blank; also means for regulating the feeding mechanism of the model and the blank independently of the generator, where the generator, model-feed and blank are driven from a common source of power.
The invention will be more fully explained in the following description, reference being had to the accompanying drawings, in which is shown one form of apparatus by the aid of which the invention may be practised.

Fig. 10 is a view from the front of the machine with the casing broken away; and Fig. ll is a view in rear elevation of the machine to show the arrangement of levers, etc.
The machine herein shown for practising my invention comprises a generator 1 of any suitable construction, taking in the instance illustrated the form of a rotary cutter mounted upon, and actuated by, a vertical shaft 2 carried in bearings 3 near the end of a swinging arm 4 mounted securely, as by shrinking or otherwise, upon a vertical shaft 5, the latter being removably and rotatably mounted in a hollow bearing bushing 6, (see Fig. 9) carried by the vcasing 7, which may rest on a table or other suitable support and be secured thereto by fastening means passing through the lugs 8.
The hollow bushing 6 may serve as the bearing for the main actuating pulley 12 of the machine, actuated by any suitable means, one convenient form of such actuating means being illustrated at 9 which designates a belt running around idle direction pulleys 10 and 11,. (from a suitable source of power not shown) to the lower groove of the pulley 12 loose on the vertical ybushing 6, the upper groove of this pulley serving to receive a belt 13 running to a pulley 14 on and driving the vertical generator shaft 2 and its attached rotary cutter 1 whatever the angular position of the swing arm 4. 15 is a take-up pulley for the belt 13, (see Fig.,2).
The disk or blank 16 to be cut to pattern or otherwise shaped, (see Fig. 2) is mounted in the same horizontal plane with the generator 1, which cuts into the periphery of the blank to a degree depending on the distance between the aXes of the cutter and blank, this being determined by the angular position of the swing arm 4 relatively to the longitudinal axis of the machine. This angular positioning of the generator arm may be regulated by any convenient and suitable means, manual or mechanical, and in Figs. 1 and 2 I have shown a follower and regulating device 17 of a character especially useful in copying the sole 1S of a shoe 19 whose upper 2O is presented by the operator for running` engagement with the nose o-f the follower. A spring dog or plunger 21 mounted at 22 in the casing 6 presses against the heel 23of. the swing arm,
normally forcing the generator and fol-v lower leftward to engage the disk 16 and shoe upper 20 respectively. In the instance illustrated, the follower 17 4is mounted, (pivotally preferably, to permit smooth traversal by the shoe) near the free end of an arm 24 connected with the swing arm 4, and which may be Yformed integrally or as aunitary structure with the latter and swinging therewith over the sole edge portion 25 as the operator `moves the same along past a guide or abutment 26.
The sole edge narrows toward the tip in the instance illust-rated, and as the operator passes the shoe along towardy the left, from the position shown in Fig. 2, until the point 27 is reached, maintaining the edge 25 of the sole in engagement with the abutshould correspond closelyin detail with the contourof the sole edge 18-27 and thence along the opposite side of the' sample shoe,
and in order to insure the movement of the sample at a speed bearing a fixed ratio to that of the disk which is being cut to patf tern, whether the speed be higher or lower, I prefer to construct-the abutment 26 as a rotary part and provide for its co-rotation with the vertical post 30 carrying the disk 16, by suitable connections with the main actuating pulley 12. In the instance illustrated I have shown for this purpose a horizontally disposed counter shaft 31 mounted rotatively in bearings 32, (see Fig. 1) on the base of the machine and driven by a spiral gear 33 meshing with a worm 34 on ,the hub of the pulley 12, the counter shaft 31 carrying a sleeve member 35 provided with a driving worm 36 which meshes with a gear' 37 on the vertical shaft 38 (see Fig. 4), and through it and the clutch 71 drives the pattern blank disk 16.
The rotary abutment or feed wheel 26 (see Fig. 3) receives its actuation through 'a vertical shaft 39 mounted in a frame pillar 40 and carrying a relatively small gear 41 which meshes with a 'largerintermediate gear 42 mounted on a stud or bolt 43, and actuated in turn by a gear 44 fast on the vertical shaft 38. The gears 42 and are preferably considerably larger than the gear 41, to cause faster rotation of the rotary abutment or feeder 26 thanof the disk 16, and the abutment' preferably has pehipheral teeth or roughnessesto engage and feed positively the sole-edge pressed thereagainst, and may have a guide flange 45 tofposition t-he sole properly with relation to the feed wheel; and also to position the upper 2O with relation to theA` follower 17, as seen best in Fig. 3.
In order to permit stoppage of the rotation of the pattern blank disk at any de.
sired point regardless of the continued ro-. tation of the main actuating pulley 12 and the generator 1, I 'prefer to interpose a clutch device between the counter shaft 31 and the feed devices, and as one convenient form of such a clutch device (see Fig. 7) I have formed the worm 36 upon a sleeve 35 mounted loosely on t-he counter shaft '31 between collars 46, 47 fastened to the shaft by pins 48, this worm sleeve constituting one member of the clutch, and preferably being provided with a split brake block consisting of two halves 49, 50 embracing the sleeve 35 and secured in adjusted position by a screw 51. rIhis brake serves to stop the worm sleeve promptly upon disengagement of the clutch, so that the pattern blank disk will not be fed improperly. The other member of the clutch (See Fig. 7) consists of a cap 52 having a head portion 53 provided with a pin 54 traversing a slot 55 in the shaft 31 and serving to communicate the motion of the shaft 31 to the cap, which in turn operates the worm sleeve through the medium of a pin 56 and socket 57 connection. The cap 53 can be grasped manually and drawn outward axially toward the left to disengage the sockets from the pins, when the action of the brake 49, 50 will stop the rotation of the worm sleeve 35; but the cap cannot be withdrawn completely from the shaft without removal of the pin 54.
Preferably the disengagement of the clutch members will be effected before withorawal of the sample shoe from engagement with the abutment 26 and the follower 17, in order to avoid the undue cutting away of the periphery of the pattern, which would result normally under the action of the cutter 1 pressed thereagainst by the spring plunger 21.
The swing arm 4 may be moved outward againstthe action of the plunger 21 to swing the cutter away from the disk by any suitable means, and as one convenient form of such means I have shown (see Fig. 6) a bell crank lever 5S mounted pivotally at 59 upon the base of the machine, one arm 60 of the lever extending upward into position to engage a coperating depending arm 61 integral with the swing arm, while the other arm 62 of the bell crank extends outward beyond the frame of the machine and is provided with a connecting rod 63 extending downward to a treadle or other suitable operating device, (see Fig. 1). After the swing arm has been moved outwardly by this means, I prefer to utilize suitable means to hold it positively at its outer position of disengagement. One suitable device for this purpose is illustrated at 64 which designates a dog mounted pivotally upon a rod 65 carried in lugs 66 upon the top of the machine base. Normally this dog will be left in the upright position shown in Fig. 1, where it does not interfere with free swinging of the arm 4 toward the pattern blank disk, but when the dog 64 is moved down into a horizontal position by the operator, the dog will be engaged by the portion 67 of the arm 4 and the arm will be held outward away from the disk. A similar dog 68 may be provided, of such a length that when it th erefrom.
is lowered into horizontal position it will stop the arm 4 in such a position that the cutter 1 will engage the periphery of the disk 16 only slightly and will cut automatically to a given radius the limb of the disk, z'. e. that portion of the periphery which will be inactive in the sole rounding or other machine in which it is used eventually.
Among the important objects of my invention, one of the most notable is the provision o-f means to enable ready application of the pattern blank disks to the vertical actuating shaft 88, and their easy removal The means which I prefer to use for this purpose may be seen best by reference to Fig. 4, in which the reference numeral 30 designates a post member having a threaded shank 69, entering a threaded axial recess 7 0 in the upper end of the shaft 3S, the latter' having a driving clutch member consisting of a collar or flange 71 secured to the shaft by a pin 72, preferably at a shoulder 78 provided to lsupport the driving memberi or the flange 71 may be integral with the shaft 88.
The collar 71 is shown as having a beveled periphery 74 to receive a cooperating friction clutch member 75 and drive it frictionally to actuate the disks to be cut to pattern, and this driven member may be connected operatively with the disks by any suitable means. As one convenient form of such means, I have shown a spline 76 arranged vertically within notches, one in the periphery of the clutch member 75 designated by the reference numeral 77 and another in the periphery of the hub device 78, this notch being designated by the reference numeral 79, the spline being held by a peg or post 8O inserted in a socket in one of the members, preferably the hub, in such a position that the spline extends vertically across from the clutch to the hub and also into a slotI S1 in the disk 16, thus coupling the clutch, hub and disk together. lVhen the shaft 38 is rotated and with it the flange 71, the clutch member 75 is rotated also by frictional engagement with the flange, and in its turn rotates the hub 7S through the medium of the spline 76, and at the same time rotates the pattern blank disk 16 carried by the hub, the disk having an aXial aperture 82 to receive the boss S3 on the lower side of the hub. By making the post member 30 of the shaft suiiiciently long, room can be provided to receive a plurality of disks as 16, 85, at the same time, as shown in Figs. 4 and 5, each having preferably a hub as 7S, 86 and a spline 76, 87.
Suitable means sho-uld be provided to retain the pattern blank disks in adjusted position and as one convenient form of such means, I have shown the post 30 as having a washer or washers S8 to overlie the adja- (see Fig. 1) which permits the washer to embrace the threaded end 69 or a reduced portion 90 of the post, while the thumbscrew wings 91 are secured pivotally by a pin '92 in a slot 98 in the upper end of the shank of the thumb-screw, so that they can be turned upwardly into the position 4indicated in dotted lines in Fig. 4, so that after the washer 88 has been withdrawn the hub 83 can be raised readily and removed over i. the head of the thumb-screw and an uncut pattern blank disk substituted for engagement by the cutter. y
After one disk has been cut to pattern, in the inanner already described in connection with the use of a sample shoe as the primary pattern, I contemplate the super-position thereon of another pattern blankdisk, as shown at 85 in Fig. 4, and the sample shoe may then be omitted, the disk 16 alshown in Fig. 4. The lower position shown in Fig. 4 is occupied by it when a single pattern is being shaped. Two pattern blank disks may be cut to pattern at once by using Y asuiiiciently long cutter as indicated by dot-ted lines in Fig. 4.
It. is important that the cutting operation should begin always at a predetermined point, and to regulate this automatically any suitable means may be provided. I have shown for this purpose a swing arm 95 mounted pivotally above the top ofthe casing at y96 upon a bolt 4S, which serves also in the instance illustrated as the vertical bearing for the intermediate gear V42. The arm has preferably a beveledtip at its free end which can be held manually against the pattern blank disk support'75y until the latter brings a notch 97 oppositev the tip 98 andthe tip enters the notch. When the machine is ready for operation the tip maybe withdrawn readily by'swinging the dog outward, orit will clear yitself from the Knotch when the machine is started.
Another important object lof my invention is to provide means tok mark upon the disk suitable indexV points which. can be readily observed by the operator who uses the disk upon a sole ro-unding or other suitable machine, so that the operator' 'can 'readily determine how to set the stops in [that machine so as to controlproperly rovice 118.
Iscrew post having been raised into the posiltation of theV pattern disk, it being understood that in a sole rounding machine the rounding devices operate upon the edge of the sole to an extent corresponding exactly with the radius ofthe pattern at any given point. For example, referring to Fig. 2, the dot designated by the reference numeral 99, serves as a mark to indicate to the operator of the rounding machine that a certain stop is to be larranged for stoppage of the pattern disk, inasmuch as that portion of the periphery of the pattern disk adjacent the dot serves tocontrol the rounding of the tip, the, pattern having itself been cut away in correspondence with the relatively narrow portion of the sole edge of the sample shoe at the region designated by the reference numeral 27, in Fig. 2. p
As a convenient form of pattern marking device, I have shown (see Figs. 2 and 8) a point` 100 carried near the free end of the spring shank 101 of a hammer device 102 pivoted, as at 103, in a suitable housing or support 104 secured in the instance illustrated upon the top of the arm 4 by screws 105. The hammer has an upwardly projecting portion 106 against which bears a latter, but in such close proximity that the resiliency of the shank 101 will permit the point to engage the face under the influence of the hammer, as will now be described.v Upon the heel 112v of thehammer, Ihave shown a pivoted latch 113 engagedby a spring 114 normally pressing the latchoutward into `engagement with the periphery of a rock shaft orV trigger 115 mounted ink a horizontal bearing in which it can be rotated'by a crank 116 (see Figs. 1A and 2) having a connecting rod 117 running down' to a treadle or other suitable operating de- The rock shaft 115 has a notch 119 the wall of which catches the latch when the operator rotates the rock shaft by de pressing the treadle, and upon further rotation of the rock shaft, the latch is crowdedy out of the notch, releases the heel ofthe hammer and the latter is forced downward by theY action of the spring 109, which results in a sharp, staccato blow of the point 100, causing a slight but perceptible indentation of the disk 16, as at the point designated by the reference numeral 99 in Fig. 2. The rock shaft trigger 115 is returned to normal posit-ion by a spring k120 acting upon release of theconnecting rod 117. The general operation kof the machine is' as follows :--,The wings y91 of the thumb Q tion illustrated in dotted lines in Fig. 4, the disk orpattern blank 16 with its hub 78 is placed over the upraised wings and dropped down into position over the clutch member 75, with the spline or connector 76 extending from the notch 79 of the hub into the notch 77 of the clutch member. The washer 88 is then applied horizontally with its notch 89 upon `the threaded portion 69 of the thumb screw post, the wings of the latter are turned downward and the thumb screw tightened to hold the hub and' disk snugly in place upon the clutch, which is cro-wded against the flange 74. If the cutter 1 is not already rotating, the belt 9 may now be set in motion, and after the portion 18 of the shoe sole has been placed in contact with the abutment 26 as illustrated in Figs. 1 and 2, the dog 64 is raised to permit the plunger 21 to swing the arm 4 around to bring the generator 1 into operative cutting engagement with the periphery of the disk 16, this being the position shown in Fig. 2, where the cutter has entered deeply into the disk and shaped the disk at that point in correspondence with the relatively wide edge of the sole at the portion 18. r[his deep cut is permitted by the relatively' large displacement of the follower 17 which has swung over into engagement with the upper at 20. The operator then presses in the clutch cap 53, the tip of the arm 95 is cleared from the notch 97 and the rotation of the counter shaft 31 is transmitted through the worm 36 to the gear 37, shaft 38 and thereby to the gears 44, 42 and 41, and the shaft 39.
The abutment 26 is thus rotated to feed the sole edge 18-25-27 along from right to left, the narrowing width permitting the upper to crowd back the follower 17, and at the same time the pattern blank disk 16 is rotated by 'the shaft 38 in the direction of the arrow, at a much lower speed, in the instance illustrated, but at a proportionately constant ratio, so that the narrowing peripheral cut indicated by the broad dots in Fig. 2 corresponds exactly in contour with the varying width of the sole edge. The operator should maint-ain the sole edge in true tangency with the rotary abutment at a point lying in a line passing from the axis of the rotary abutment through the midpoint 121 of the follower 17, and to assist the operator in accomplishing this I have shown a mark on the follower at the midpoint 121 and a corresponding mark 122 on the adjacent arm 24, these marks, when alined, indicating that the sole is properly positioned. After the portion 18-25-27 has traversed the follower, the opposite side of the sole edge is caused to traverse in like fashion, from the point 27 to the point 29 &c. causing the pattern to be shaped, and then the dog 68 is dropped, the arm 4 allowed to rest thereagainst, and the limb of the pat-tern is shaped automatically to a circle of predetermined radius. This completes the operation and the operator will then depress the rod 63, throwing out the arm 4 and cutter 1; will drop the dog 64 to hold the cutter away from the pattern; and will replace the pattern by a new blank disk, first loosening slightly the thumb screw, raising its wings 91, sliding out the washer 88 and withdrawing the disk 16. As already indicated, the pattern 16 may alternatively be left in place to serve as a master pattern, in which event a fresh pattern blank disk 85 (see Fig. 4) provided with a hub 86 and spline 87 will be imposed upon the hub 78, and the upper washer 88 will be placed in the upper groove 90 of the stud 30, presenting the appearance shown in Fig. 1. The retaining nut 123 and the cutter 1 will be removed from the generator actuating shaft 2, a follower disk or roll 94 will be applied to the shaft 2 and the cutter and retaining nut will be replaced, after which the swing arm 4 may be released and the clutch 53 coupled. rl`he follower roll or disk 94 will be forced, by the action of the plunger 21, into engagement with the periphery of the master pattern 16 at all points, accompanied by similar cutting engagement of the generator 1 with the pattern blank disk 85, which will thus be shaped as an exact replica of the master pattern 16, and further replicas may be produced automatically without further attention to the machine than is involved in removing each replica as it is finished and substituting a fresh pattern blank disk. l
Vhile, in the use of a machine embodying this invention for producing a pattern or a cam to be used in the manufacture of shoes, it may be more convenient to employ a sample shoe as a model in the manner hereinbefore described, it should, nevertheless, be understood that the invention is not limited to the use of a shoe as a model; although it is essential that such model as is employed shall have a shape corresponding in certain desired characteristics with the article in the manufacture of which the pattern is ultimately to be used.
