To all 107mm it may concern Be it known that I, Enasros E. VVINKLEY, citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Sole-Leveling 'I lowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art-to which it apperre-lasted, the sole is more or less wrinkled and distorted, and also has a well defined ridge extending along its margin, which was produced by the bending or molding of the edge away from the lip previous to the sewing of the upper to the sole. In leveling the sole by hand the operator first removes this ridge and stretches the sole outward around its margin by the use of a suitable bar or; stick with which he'produces an outward wiping and pressing action, by giving the stick a combined longitudinal and lateral movement while hel'd'diagonally across the margin of the sole, Having thus stretched and pressed the outer'margin of rthefisole the operator subjects the shank of the sole to repeated blows with a hammer or block, thus hammering and shaping the shank portion of the sole and conforming the same to the shape of'the last The operator then finally presses and shapes both the forepart and shank by the use of a rub stick which he holds transversely and reciprocates longitudinally of the'sole while pressing it against the sole and changing its inclination .to properly give the sole the desired shape.

I It is the object of the present invention to provide a machine by which the sole of a turned shoe may be acted upon in substan tially the same way asin the handleveling' operation, and maybe subjected to outward shape. Machines; and I do hereby declare tne r"o1 and is operated upon erating upon the sole may be as nearly as SOLE-LEVELING Mnonrnn.

stretching and compressing action about its margin, to a hammering action upon its" shank or other desired part, and to a final rubbing and pressing action over'both the shank and forepart to bring it to its final In' a machine embodying the present in-; vention the shoe is supported upon a jack, by the sole leveling mechanism, while a relative movement is produced between the ack and leveling mechanism to transfer the point of operation of theleveling mechanism over the shoe sole. The sole leveling mechanism is constructed and arranged to 'subject'the margin of the sole to a progressive outward wiping pressure which stretches thesole outward along its margin and removes the marginal ridge,

to subject the sole. to successive blows, to

hammer and shape the shank or other parts of the sole, and to. subject the sole to a progressive longitudinal rubbing to give it its final shape, so that the sole may be subjected to substantially the same operations as in the hand method of leveling.

In its broader aspects the invention con-- templates the provision of any suitable form of leveling mechanism adapted to subject the sole to the operations above outlined as the point of operationof the leveling mechanism is transferred along the sole by the relative movement between the leveling mechanism and the shoe supporting jack. For the sake of compactness and simplicity inconstruction, it ispreferred to employ a leveling mechanism'comprising a single device for contacting with the surface of the sole, and means for supporting and actuating the device to perform'the various operations 'upon the sole. This sole engaging or leveling device may be of any suitable form and any suitable mechanism may be employed for operating" and controlling it;

Assreivon To UNITED error: I

In order that the action of the device in op-.

practicable that of the hand manipulated rub sticln'itis preferred to employ a leveling device in the form of a bar' orrod con- 1 structed ,to properly actupon the sole and forming in effect a rub stick; v The various features of the invention will be clearly understood from an inspection of the accompanying drawings-illustrating a machine embodying the broader features of the invention in thirpreferred form, and

also embodying certain novel constructions and arrangement of parts, which will he hereinafter described and more definitely referred to in the claims.

In the drawings Figure 1 is a side elevation of the machine; Fig. 2 is a front elevation; Fig. 3 is a partial side elevation on a larger scale showing the leveling device and the operating and controlling mechanism therefor looking toward the left in Fig. :2; Fig. 4 is asimilar side elevation looking: toward the right in Fig. 2; Fig. 5 is a plan view of the partsshown in Figs. 3 and 4:; Fig. 6 is a detail front elevation of the level ing device; Fig. 7 is a vertical sectional view on line a-a, 5; Fig. 8 is a vertical sectional view on line 6-4), Fig. 7; Fig. 9 is a vertical sectional View on line 0-0, Fig. 7 Fig. 10 is a horizontal sectional view on line cZ-rl, Fig. 7 Fig. 11 is a partial vertical sectional view online a 6, Fig. 2; Fig. 12 is a sectional view on line f-f, Fig. 2; and Fig. 18 is a horizontal sectional view on lineg-g, Fig. 12..

In the construction shown the relative movements between the jack and leveling device for transferring the point of operation of theleveling device along the shoe sole and for changing the relative lateral inclination of the jack and leveling device to give the proper shape or curvature to the shoe sole are produced by movements imparted to the jack.

The leveling device consists of a bar or rub stick arranged to press upon the sole, and adjusted and operated during the travel and tilting of the jack tosecure the proper action upon the sole in accordance with the part of the sole being operated upon, and in accordance with the different stages in the leveling operation. As the jack travels forward at the beginning of'the leveling operation, the rub stick is held obliquely or at an inclination to its direction of travel across one margin of the sole, and is given a transverse reciprocation while pressed against the sole so that it produces a progressive outward pressing and stretching action upon the sole margin during its forward movement. During the forward stroke of the rub stick the jack remains stae tionary, while during. the return stroke of the rub'stick the jack is given an advance movement. The rub st1ck therefore effects itsrubb ng and outward stretching action during its advance stroke, while during'its return stroke the jack advances sothat there 1s substantially no rubbing actlon during the return stroke of the obliquely disposed rub stick. This outward rubbing and stretching action continues during the entire advance movement of thejack, {LIlCllllle til the rub stick reaches the breast of the heel. The pressure upon the rub stick is -then. relieved, and: the jackreturns to its initial position. Before the jack starts forward again the inclination of the rub stick with relation to its line of travel is changed, and the ack is tilted so that the rub stick is properly positioned to act upon the other side of the sole. During the next advance movement of the jack the rub stick is pressed againstthe sole, and acts to press and outwardly stretch this margin of the sole. At the end of this advance movement of the jack, or when the rub stick has reached the breast of the heel seat, the angular position of the rub stick is changed so that it extends transversely across the sole at substantially right angles to its longitudinal movement, and the transverse reciprocation of the rub k ceases. As the jack is retracted to on y the rub stick over the shank the rub stick is subjected to a series of blows, and the jack is properly tilted so that one side of the shank is hammered and' shaped. "il hen the rub stick reaches the front end of the shank, the jack is rocked to bring the rub stick into contact with the other side of the sole, and the jack is then advanced until the rub stick reaches the breast of the heel on this side of the sole, the rub stick being still operated to hammer and shape this side of the shank. The hammering action then ceases, and as the jack is retracted the rub stics is reciprocated longitudinally of the sole, the ack being tilted to secure the proper relative lateral inclination between the jack and rub stick to properly shape the sole. This longitudinal rubbing action continues until. the too is reached, and then the jack is tilted to bring the rub stick into operation upon the opposite side of the sole, the jack is then advanced, the longitudinal rubbing action of the rub stick continuing until the breast of the heel is reached. The jack is then tilted to bring the rub stick into operation upon the central portion of the sole, and the jack is retracted to its initial position. This completes the leveling operation, and the machine is stopped, pre paratory to the leveling of another shoe.

The jack comprises a main yoke or frame 1 which is pivotally mounted at 2, and a sec-- 'ond yoke or frame 3 which is pivoted at the point 4 in the frame 1 and is provided with ed shoe in position thereon. The frame 1 is oscillated about the pivot 2 to cause a relative movement between the jack and leveling device longitudinally of the shoe sole by means of a lever 5 which is pivoted at 6 and is connected with the frame 1 by means of a link 7. This lever carries aroll 8 which engages a cam groove in the disk 9 which is secured to the main cam shaft 10 of the machine. The frame 3 is rocked upon the pivots 4 to change therelative lateral inclination between the shoe sole and leveling device through a leverwll which is pivoted jack supporting shaft 2. The groove in the collar is also engaged by a roll. on one arm 16 of. a bell crank lever. The other arm 17 of the bell cranklever is connected by means of a link 18 with the front end of a lever 19 which is pivoted upon the rod 6 and these connections,

' (Fig. 13). The arm,

is provided with a roll 20 arranged, to engage a cam groove in the cam disk 9. By motion is transmitted from the cam groove in the disk 9 to the frame 3 without interferingwith the swingin movements of the'frame 1. i

The cam shaft 10 is driven through a worm 21 and a worm wheel 22 from a shaft 23 which is in turn driven from the driving shaft 24 through spiral gears 25. The driving shaft is provided with a driving pulley 26 loosely mounted thereon and adapted to be connected with and disconnected from the shaft by a clutch 27. The clutch is operated to start and stop the machine through a controlling rod 28 which is mounted to rock and slide longitudinally and is connected with the clutch so that the longitudinal movements of the rod engage and disenga e the clutch. The rod-is provided with collars 29 engaging'opposite sides of a pin which is carried by an arm 30 secured to the lower end of a rock shaft 31, the upper end of which carries, an arm 32 which is connected by a link 33 with the clutch operating lever 34 (Figs. 1, 2, 11, Y12 and 13). The clutch operating and controlling rod 28 is forced in a direction to engage the clutch by a spring 35, and is provided with an arm.

36arranged to be engaged by a pin 37 pro jecting from the side of the worm wheel 22. lV'hen during the revolution of the cam shaft 10 the pin 37 engages. the arm 36 on the clutch operating rod, it moves the rod longitudinally and disengages the clutch, thereby stopping the machine. When the machine is to be started, the operator depresses a tr-eadle 38 which is secured to the front end of the rod 28, thereby rocking the rod and disengaging the arm'36 from the pin 37. The rod is then shifted by the spring to engage the clutch and start the machine. hen the rod 28 is rocked to start the machine, and is moved longitudinally by this spring, an arm 39 which is secured to the rod passes backof a fixed lug 40, so that when the treadle 38 is released the arm 39 engages the lug 40 and holds the rod in position against the tension of a spring 41 36 is thus held from en gagement with the side of the worm wheel 22 during the operation of the machine. When the treadle 38 is depressed, the clutch will be engaged withfthe driving pulley, and

j about, the shaft 44 and the operating lever 53. device may he therefore yleldingly forced [the cam shaft and other parts of the machine will be driven until the cam shaft has made a complete revolution, when the clutch will be disengaged and the machine stopped. During-the oscillation of the jack about the pivot 2 the sole of the shoe carried upon the jack is acted uponby a leveling device. The leveling device and the de'vicesby which it is controlledand moved-during its action upon the sole are supported, and carried upon a movable frame 42.- i This frame is provided with rea'rwardly projecting lugs 43 bywhich it is pivotally supported upon a shaft 44 which is mounted in the arms 45 of a bracket 46. The frame is held in normal position upon the shaft 44 by means of I a spring 47 which surrounds a rod 48 and is interposed between a lug 49 on the bracket (Sand the rear side of the back-plate 50 0f the frame 42. The rod 48 extendsthrough the back-plate 50 and lug 49, and is provided with a head 5.1 at one end, and with adjusting nuts 52 at the other, so that by adjusting the nuts the normal position of the frame may be regulated. The frame 42 is swung to give vertical movements to theleveling device, or to regulate the pressure of the leveling device upon the ;sole by means of a lever 53, the rear end of which is pivoted, on the rod 6, and the front I end of which is connected with the frame 42 ,through a link rod 54. The lever 53 isoperated by a cam groove 55 formed in theface ,of the worm wheel 22 and engaged by a roll on the lever. The upper end of the linkrod 54 passes through a yoke 56 which is hung upon a shaft 57 mounted in the side pieces 58 of the frame 42 (Figs. 7 and8). A spring .59 is interposed between the upper side of the yoke 56-and a collar 60 mounted on the upper end of the link rod 54, so that there is a yielding connection between the frame 42 The leveling against the sole, or the pressure relieved during the operation of the machine, by the actionv of the cam 55. I

The leveling device in the form shown consists of a bar 61 formed to .act upon the sole during oertainstages of the leveling operation in the manner of a rub stick, and constituting at such times an automatically manipulated rub stick. The rub stick or bar 61 is pivotally mounted at its ends in bearings projecting downward from a block 62. The lowerlsu'r'face of the'rub stick is arranged substantially in the plane of the axis about which the stick may turn, and the upper surface of the stick is concentric with the axis and is arranged to engage a corre sponding surface in the' under side ofthe block 62. The block .62 which carries the rub stick or bar is supported in the front ends of two parallel arms 63,.the rear ends of which are bifurcated and are pivotally.

connected with two bars 64: and 65 (Figs. 5 and 6). The bars 6t and 65 are mounted ugon pivots 66 and 67 secured in or formed on the front end of a head 68 which is carried by the frame 422. The pivot 66 projects upward from the head 68, while the pivot 67 projects downward from the head, the pivots being in vertical alinement and being arranged midway between the pivotal connections of the arm 63 with the bars 6d and 65. The block 62 is pivotally connected with the forward ends of the arms 63 by means of bolts 69 which extend through the ends of the arms 68 and are threaded in the block (Fig. 6). Springs 70 are interposed between the heads of the bolts 69 and the ends of the arms 63, so that the block is yieldingly held against the lower sides of the arms and may move downward with relation to the arms when the block 62 is subjected to blows or pressure in the manner to be described.

By reason of the pivotal connections between the block 62 and the arm 63, and be tween the arm 63 and the bars 64: and 65, the arms 63 form parallel links for supporting the block 62 and rubstick or bar and maintaining it always in parallel relation with the bars 6-1 and 65.

The upper member of the bifurcated arm 63 at the left in 5 is extended beyond the pivotal connection between the arm and the bar 64, and is connected by means of a link 71 to the front end of a lever 72 which is pivoted upon a vertical rod 73. The lever 72 may be held in fixed position to maintain the block 62 and the rub stick in fixed parallel relation to the bar 64, or may be oscillated about its pivot to reciprocate the rub stick transversely of the sole upon which it is operating. The lever 72 is provided with a vertical bearing 74 in which is mounted a sliding pin 75, so arranged that its upper end may be engaged with a hole 7 6 formed in a cross-bar 77 of the frame L2 when the lever 7 is to be held stationary, and that its lower end may be engaged with a cam groove formed in a cam drum 78 when the lever 72 is to be oscillated. The pin is moved longitudinally to either engage the upper end with the hole in the bar 77, or to engage the lower end with the cam 78 through a lever 79 pivotally mounted be- "tween supports 80 on the lever 7 2, and having its forward end connected with the pin 7 5, and its rear end connected with the rod 73. The rod 7 3 is mounted to slide in a vertical bearing 81 in the. rear plate of the frame a2, and is connected at its lower end with an arm 82 (Fig. 7 The arm 82 is socured upon a rock shaft 88 mounted in one end of the plates of the frame 42, and provided atits outer end with a second arm 8% which carries a roll 85 at its outer end arranged to engage a cam groove 86 formed in the face of a cam drum 87. The cam drum 87 is secured to the shaft 57 which has been heretofore referred to and which is intermi ttently rotated by a mechanism which will be described later. Through these connections the cam 86 operates the pin 75 to either connect the lever 72 with the frame 42 so that the lever is held stationary, or to connect the lever with the cam 78 so that the lever is oscillated to vibrate the bar 62 and th rub stick transversely of the sole being operated upon.

The angle of the rub stick with relation to the longitudinal movement of the sole being operated upon may be varied so that the rub stick is at right angles to the direction of movement of the sole, or is inclined to the direction of movement in either clirection by swinging the

bars

64 and 65 about their pivots, the parallel link arms 63 acting to maintain the rub stick parallel to the bars 6% and 65. -For the purpose of thus varying the angular relation of the rub stick to the longitudinal movement of the sole being operated upon, the bar 64: is provided with a rearwardly projecting arm 89 which is connected by link 90 with the front end of a lever 91. The lever 91 consists of two arms connected by a vertical web 92 (Figs. 1, 5, 8, 9 and 1.0). The rear ends of the arms are arranged above and below a boss 93 on the frame a2, and are p-ivotally mounted upon a stud 9-iextending through the arms and the boss. The upper arm of the lever 91 is pivotally connected with the link 90, and the lower arm is provided at its forward end with a roll engaging a cam gro ve 95 formed in cam drum 96 which is secured to the intermittently moving shaft 57. By these con- .ilECblOllS the bar 6-]: may be swung about its pivot to vary the angular relation of the rub stick while operating in accordance with the side of the sole being operated upon or the stage in the leveling operation upon the sole, the angular relation of the rub stick during any period in the operation upon the sole being determined by the cam 95.

The mechanism for reciprocating the supporting head 68 during certain periods of the leveling operation to move the rub stick back and forth longitudinally of the sole. being operated upon, and for holding it in fixed position in the carrying frame 42 during other periods of the leveling operation is as follows: The head is supported at its front end by means of a pin 88 engaging guiding slots formed in the arms 88*, which extend forward from the sides 58 of the frame 42. The rear end of the head is supported and guided upon rectangular blocks mounted upon a shaft and engaging slots 98 in the arm 97 which extend from the rear end of the head (Figs. 5 to 10). The shaft 100 is journaled in the end of the plates 58 of the frame .42. -The arms 97 are also provided with vertical slots 101 engaged by rectangular blocks 102 which are carried upon pivot pins 103 in the upper ends of arms 101 which are formed on a sleeve 105. The sleeve ismounted upon a rod'106 mountedin the end plates 58 of the frame 42. One of the pivot pins 103 is connected by a link 107 with the lower end of a lever 108, the upper end of which is pivotally supported upon a rod109. The lever 108 may be locked in fixed position, in which, case the head 68 has no reciprocatory move ment, or the lever 108 may be connected with a cam 110 carried by the shaft 100, in which casethe head 68 will be reciprocated. For thus connecting the lever 108 in fixed position, or connecting it with the cam, a bolt 111 is mounted in the lever 108, and is ar ranged to be either engaged with a hole 112' formed in alug113 projecting from the back-plate of the frame 42, or to be engaged with a cam groove 114 formed in the face of the cam drum 78 which issecured upon the shaft100. The bolt 111 is operated through a lever 115 pivotally mounted in supports 116 on the lever 108, and connected at one endwith the bolt 111, and at the other end with the rod 109. The rod 109 is mounted to slide longitudinally through the end plates of the frame 12, and is connected at its outer end with an arm 117 whichprojects upward from a sleeve 118 (Figs. 2 and 4). The sleeve 118 is mounted upon a shaft.

. 119 supported in bearings 120 0110116 of the end plates 58 of the frame '42, and is provided with a downwardly extending arm 121 through which it 'is rocked. The lower end of the arm 121 is provided-with a a toothed segment 122 mounted to, engage segment 123 formed on the front end of a lever 121. The rear end of the lever124 is mounted upon a pivot 125,- and the front I end is provided with a roll engaging a cam groove 126 formed in the periphery of the cam drum 87. Throughrthese COIlIlQOtlOIlS,

the'fbolt 111 is operated by the cam 126 to connect the lever 108 with the cam 110, or to lock the lever in position.

When operating upon the shank of the sole, the leveling device is operated to de liver blows upon the sole perpendicular to the surface being acted upon, thus giving ahammering action. In the' construction shown the rub stick or bar 62 is operated upon to deliver blows upon the sole by a hammer block 128 mounted in the front end of a. lever 129 and arranged to act upon an upward projection 130 on the block 62 (Figs. 6 and 7). The hammer block 128 is connected with the lever 129 by means of a stud 131 which projects up through the lever and is provided with a nut 132. A

spring 133 is interposed between a shoulder on the stud 131 and the bottom of a recess p in the end of the lever, and acts to yieldingly hold the hammer block in position,

and to form a cushion forcushioning the sole, the roll 136 is held in position to be operated upon by a cam 138 which is secured to the shaft 100 between the arms 97 of the head 68. When the hammering operation is to cease, the roll 136 is shifted on the stud 137, so that it is out of register with the cam, and is held in this position until the hammering operation is'to be resumed. The roll'136 is thus moved to control the time during which the hammering operation is performed through a longitudinally movable bar139 which is mounted in the end plates of the frame 42, and is provided with a yoke 110 the arms of which embrace the roll 136' (Figs. 5, 7 and 8). The rod 139-extends'beyond the righthand end plate 58 of the frame 42, and at its outer end is connected to the upper end of a lever 141. The lever 141 is pivoted at 142 in an arm which projects from the end plate 58, and is provided at its lowerend with a gear segment 143 which engages a. segment 111 formed on the front end'o-f a lever 145. The lever 145 is pivoted at its rear end upon a stud secured in a boss 146 formed on'the frame 42, and is proengages a: cam groove 148 formed in the cam drum 96. By these connections the" cam groove 148acts to shiftthe roll 136 into and out ofposition to, beengaged by the cam.

.vided at its front end with a roll 147 which i 138, and thus controls and times'the ham mering operation.

. -The shaft 100 which carries the cams for effecting the hammering operation,"for reciprocating' the head 68, and for causing a longitudinal reciprocation'of the leveling device, is continuously driven during the operation of the machine through a gear 149 secured to one end of the shaft, and engaging a gear 150 secured to the shaft 41. The shaft 44 is driven from the driving shaft 24 through a chain 151 which passes "over

sprocket wheels

152 and 153 secured upon the

shafts

44 and 24 respectively.

The cam shaft 57 which carries the timing and controlling cams which control the relation of the leveling device to the sole and U the operation of the leveling device upon the different parts of the sole, is intermittently driven from the shaft 100 throiwh a mechanism which advances the shaft 5 through a partial revolution for eachrevolutionof'the shaft 100. This mechanism consists of a disk 154 arranged to engage a series of lockr the notches 157 and advances the shaft 57 the distance between successive notches, and then during the remainder of the revolution of the shaft 100 the disk co'ciperates with the locking segments 155 to lock and firmly hold the shaft 57 and the attached timing and controlling cams in fixed position.

By properly shaping the timing and controlling cams carried by the shaft 57, the relation of the leveling device to the sole, and the operation of the leveling device upon the sole, may be controlled to vary the action of the leveling device upon different parts of the sole, and to cause the leveling device to act in the desired manner upon the different parts of the sole.

The machine illustrated is adapted to perform all the operations incident to the leveling of the soles of turned shoes and the operation and ,control of the jack and leveling mechanism is fully automatic. This is not essential, however, to the broader features of the invention, which may be embodied with advantage in machines which are not adapted to perform all the operations described, and in machines in which the adjustment or control of the coiiperating parts is effected to a greater or less extent by the operator. The construction and arrangement of the leveling device or devices, and of the parts coperating therewith, may also be varied or modified without departing from the invention.

Having set forth the nature and object of the invention, and specifically described one form of apparatus in which it may be embodied, What I claim is 1. A sole leveling machine, having, in combination, a shoe supporting jack, a sole leveling device relatively movable to transfer the point of operation of the leveling device overthe sole of a shoe supported on the jack, means for holding the leveling device oblique to the direction of its travel along the shoe, and means for actuating said device to rub the sole obliquely outward first on one margin and then on the other, substantially as described.

2. A sole leveling machine, having, in combination, a shoe supporting jack and a rub stick relatively movable to transfer the point of operation of the rub stick over the sole of a shoe supported on the jack, and means forholding the rub stick diagonally across the margin of the sole and for vibrating it transversely of the sole, substantially as described.

3. A sole leveling machine, having, in combination, a shoe supporting jack and a rub stick relatively movable to transfer the.
