' To all whom it may concern.'

Be it'known that I, EnAs'rUs E. WINKLEY, a 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 Automatic Shoe-Machines; and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable other skilled in the art to which it appertains to make and use the same. g

The present invention relates to machines for operating upon boots and shoes in whichthe shoe and operating means are relatively movable to transfer the point of operation of the operating. means around the shoe, and in which the relative movements between'the shoe and means `for operating thereon are automatically controlled and effected so that the shoe is automatically presented to the operating means as the point of operation is transferred around the shoe.

The object of the invention is to provide novel and improved meansl for automatically correcting the relative position of the shoe and operating means to maintain them in proper relation at the point of operation as this pointl progresses along` the shoe, whereby the operation of the machine is rendered more uniformly certain and reliable.

To these ends the invention contemplates utilizing some predetermined contour or ,contours of the shoe to control and determine the corrective'movements requisite for maintaining the operating means and shoe in proper relation. By these means the relative movements imparted to the shoe and operating means are made to depend upon the contour of the shoe being operated upon, so that each shoe is properly presented to the operating means, notwithstanding unavoidable variations in shape which occur in different shoes, even when ofthe same style andsize. 4This also enables shoes of different size and style to be operated upon without change Ior adjustment in the correcting mechanism The contour of the shoe which may be utilized to the best advantage to control the corrective movements will depend upon the character of the machine in which the invention is to be embodied, and upon the operation which it is to perform upon the shoe. lt will usually be desirable to utilize as the controlling contour a shoulder or abutment extending along or adjacent to the margin of the shoe sole, or to utilize the surface close to such a shoulder or abutment.

The broader features of the invention may be embodied in machines for performmg various operations which are customarily performed upon partially completed shoes, and may be embodied in mechanisms for effecting any desired corrective movements4 between the shoe and operating` means.

In the specific embodiment of the invention shown in the drawings the invention is embodied in a machine-for sewing the inseam of welt or turn Shoes, and is utilized to relatively swing the shoel and sewing mechanism to maintain the channel 'forming` the inner 'surface of the between-substance parallel to the line of feed, the corrective swinging movements being imparted to a jaclr upon which the lasted shoe is sup-- ported.. ln this construction the bottom of the channel is the contour on the shoe which controls and determines the swinging movements which 'are imparted to the jack to maintain the shoe in'proper position against the channel guide during the feed of the shoe. These swinging movements are de terlnined b v a fceler which acts a longthe bottom of the channel aud causes the jack to be swung 1n accordance with the longitudinal curvature of the channel at the point where the sewing mechanism is acting on the shoe. .Each shoe is therefore manipulated by the correcting mechanism in accordance with the contour of the channel in the sole of that particular shoe to keep the bottom of the channel at the sewing point substantially in line with the line oi the feed of the shoe. i

The :various features of the invention will be readily understood from au inspection of the accompanying drawings and the following detailed description of the mechanism illustrated therein.

'lllO In the drawings Figure 1 is a side eleva` tion of an inseam sewing machine embody 2 is a side elevation showing the jack swinging the feed of the shoe. The jack `is forced yieldingly toward the sewing mechanism l by a spring bell crank lever 16, the other end of which i engages a collar 1T on the sleeve 7.

, The feeding lawl of the sewing mechanism acts in the usual manner to feed the shoe, and the shoe is swung to properly guide it ing the features of the vinvention in the forms in which it is preferred to employ when utilizing the invention to relatively swing the shoe and sewing mechanism; Fig.

ln the machine shown in the drawings the means for operating uponthe shoe consists of a sewing mechanism which is similar in construction to the construction of the wellknown Goodyear welt and turn sewing machine shown and described in Patent No. 412,704, October 8, 1889. The -shoes to be operated upon are carried upon a freely movable jack, and correcting mechanism is provided for properly swinging the jack to maintain the bottom of the channel adjacent to the point of operation of the sewy during the feed by imparting 'turning movements to the shaft S. The turning movements requisite for properly swinging the shoe during the sewing of the seam are imparted to the shaft S through

chains

18 and 19 passing about sprocket wheels 20, 21 and 22 secured to the Alower end of the

shafts

8, 12 and 14 respectively.

The swinging movements vare imparted to the shoe when the needle is in engagement with the work, and the shoe will therefore be swung about the point of operation of the sewing mechanism. In order that the shoe may be properly guided, the mechanism for swinging the shoe is so controlled by the contour of the channel is swung in accordance with the longitudinal curvature of the channel at the point of operationof the sewing mechanism to maintain the bottom of the channel in line with the feed. The-devices for thus swinging the shoe comprise a feeler 23 arranged to engage the bottom or base of the channel substantiallyI the distance of one stitch length in advance of the needle, and con-` nected to control the mechanism which imparts turning movements to the jack turning shaft S. rThe feeler 23 is in the form of l a finger pivoted to the lower end of the caris pivoted upon the end of an overhanging arm 25. The feeler finger 23 is forced yieldingly toward the surface of the sole of the shoe by a spring 26 the compression -of which may be adjusted by an adjusting screw 27 (Fig-8). The fceler carrying lever 24 is connected through a link 2S with a second lever 29, which is rier lever 24, which ing mechanism parallel with the direction of feed. The sewing mechanism is mounted upon a support 1, and is provided with a channel guide 2, a back-gage 3, a feeding awl 4, and the usual cooperating stitch forming devices. The shoe to be operated upon is carried upon a jack which is provided with heel and toe supports 5 and in turn connected through a link 30 with for supporting a lasted shoe. The jackis a lug 31 proyecting from a pulley 32. The secured upon the upper end of a sleeve 7 feeler is forced toward the base of the channel by spring 33. The pulley 32 is connected to turn in unison with a second pulley 34 through a wire belt 35 which passes about the pulleys and about guide pulleys 36, and may be tightened to takeup all slack and lost motion by a turn buckle 37. The pulley 34 is provided-with a. radially projecting arm 3S which is connected by a link 39 with one end of a sliding bar 40, the other end of which is connected by a link 41 with one arm of a bell crank lever 42 (rig. 2). crank lever carries a 1 42 secured to a cam to intermittently withdraw from engagement with the base of the channel, for a purpose to be explained. The

which surrounds a shaft 8 mounted in theouter end of a supporting arm 9. The sleeve is free to slide vertically upon the shaft, and is connected to turn with the shaft by means of asycke 19 secured to the upper end of the shaft, and having .one of its arms slotted to embrace one of the arms 11 of the jack. rhe rear end of the supporting arm 9 is mounted to turn freely about a. shaft 12 which is mounted in bearings in the outer end of a second arm 13, the rear end lof which is in turn mounted to turn freely upon a shaft 14 mounted in the frame of the machine. These supporting devices permit the jack to be moved freely in any direction in presenting a shoe to the sewing mechanism and in manipulating it durroll engaging a cam shaft 48, and act-lng that the shoeI The other end of the bell.

15 connected to one end of a the feeler finger '8 to bring the through the connect-ions between the feeler and roll carrying lever 42. The position of the roll 43 when the feeler is in engagement with the base of the channel will depend upon the position of this point in the channel with relation to the point in the channel where the stitch is being formed. The position of the roll determines the extent and direction of the turning movement which is imparted to the jack turning shaft point in the channel engaged by the feeler into the line of feed.

`The mechanism through which the roll determines the rotary movement imparted to the shaft 8, comprises a reciprocating controller plate 44 provided at its upper end with two oppositely inclined surfaces 45 adapted to pass on opposite sides of the roll 43 when the roll is in mid or neutral position. The plate 44 is pivotally mounted upon one end ot' a reciprocating `carrier lever 4G, the other end of which carries a roll engaging a cam 47 which is secured to a continuously rotating cam shaft 48. The cam shaft 48 makes one revolution for each revolution of the cam shaft of the sewing mechanism, so that the controller plate 44 is advanced and retracted during each cycle of operations of the sewing mechanism.

` The lower end of the controller plate 44 is connected through a link 49 with an arm 5C projecting through a sleeve 5l which is loosely mounted upon a shaft A second arm 53 projects from the sleeve 5l, and is connected by a link 54 with an arm or link 55. The rear end of the link 55 is pivoted to a pivot block 56 mounted to slide in a segmental slot formed in an actuator lever 57. The actuator lever is pivotally supported in a bearing 5S (Figs. 3 and A5), and the segmental slot in whichthe pivot block 56 is mounted extends on opposite sides of the pivot of the lever. The lower end of theactuator lever carries a roll which is held in engagement with a. cam 59 on the cam shaft 48 lby a spring 60. The" actuator lever is thus reciprocated during each cycle of ol'icrations of the sewing mechanism. The other end of the link is pivotally connected to a sliding bar Gl, the end of which is connected by a link G2 with one arm Iof a clutch operating lever 68. The other end of the. lever is 64 which engages a pinion formed on the hub ofthe men'iber GG of a clutch from which turning movements are in'iparted to the jack turning shaft 8. The jack turning clutch is a. double-acting l-lorton clutch, the

'driven member of which consists of a disk 67 secured tc a hollow shaft 68 (Fig. ti). This shaft carries a sprocket wheel (S9 which is connected by a chain 70 with aI sprocket wheel 7l. The sprocket wheel 7l .inactive by bell crank levers 7S.

provided with a gear segment is connected with a gear 72 engaging a gear 73 connected with the sprocket wheel through which turning movements are transmitted to the shaft clutch are forced in a,direction to wedge between the flange of the driving memberA Go' and the clutch surfaces 'T6 on the driven member GT by spring-pressed pins TT, and are forccd'back to render the clutch The bell crank levers are forced in a direction to release the clutch pawls by a spring 79, and are actuated to render the clutch inactive through a rod S() extending through the hollow shaft (SS and engaging the ends of the levers. The rod is actuated at proper intervals by a cam 8l on vthe cam shaft 4S which engages one end of a lever S2, the other end of which is connected with the upvper cnd of the rod 80.

So long as the point in the. channel which is engaged by the fceler 23 isin the line of feed.` the roll 43 will bo positioned in mid or neutral position, when the feeler engages the channel. When the roll. is in this position the inclined Surfaces 45 on the controller plate 44 will pass on opposite sides of the roll without effecting. any swinging movement of the plate. rl`he connections between the. plate and the pivot block :iti are` such that under these conditions the pivotal connection between the block and link 55 will be in line with the axis of the actuating lever 57. No turning movement will therefore be imparted to the jack swinging clutch so long as the base of tho channel remains in the line of feed. lVhenevcr the point of the channel engaged by the tcelcr is out of the line of feed, the roll l5-l will be positioned either to the right or left of the neutral position a distance proportioinll to the position of the point in the channel engaged by the lecler with relation to the line of feed. Now when the controller plate 44 is raised, one of the surfaces will ride against the roll and swing the plate about its pivot. This movement of the plate will through the connections described shift the pivot block 5G to one side or the other of the axis of the actuating lever 5T, so that during the active stroke of the lever the driving member (5o of the jack swinging clutch will operate to swing the jack and shoe through the distance requisite tor bringing the point of the channel engaged by the feeler in to the line of feed. .ls soon as the roll 43 has been positii'mcd b v the fceler, it locked and held during the advance movement ot' the controller plate by a clamp Sil arranged to engage the .sliding bar 40. This clamp is carried in one arm oil i bell crank lever 84. the other ;.rni of which carries a roll engaging an operating cani R5 secured to the cam shaft 4S. its soon as thtl controller plate The rolls 74 of the 44 has been advanced and has positioned the pivot bloclr 56, the bloclris locked in position, and the ,ontroller plate is retracted to free the rolll, the clamp 83 being also released i may be immediately withdrawn from' the channel, and so that the roll 43 may be again positioned by the feeler. The pivot block is thus locked by a clamp 86 arranged to 'engage a segment ST secured to the sleeve S6 is carried in one arm of a bell crank lever S8, the other arm of which carries a roll engaging a cam S9 on the cam shaft 4S. .A weight 90 is connecte with the sleeve 51 to counterbalance the weight of the parts connected with the sliding pivot block 56. The controller plate 44 and pivot block are returned to neutral position after each cycle of operations by a cam plate 91 provided with a V-shaped mouth arranged to engage a roll on the controller plate. A spring 92 is connected with the link 49, and tends to retract the controller plate.

The parts are shown in tl e position which they occupy after the shoe feeding movement of the feeding awl and channel guide has just been completed. Thefeeler has engaged the base of the channel and positioned the roll 43, the controller plate 44 is retracted, the pivot block 56 and the jaclr swinging clutch are in neutral position, ating lever is in its retracted position. Starting with the parts in this position, the cycle of operations performed during eac cycle of operations of the sewing mechanism is as follows: The roll 43 is locked in posi.- tion by the clamp S3, and then the controller plate 44 is raised and by its engagement with the roll 43, positions the pivot block 56 on the actuator lever 5T. The clamp 86 immediately locks the pivot bloclr in this position, and then the lever 46 which carries the controller plate is released by its cam, so that'the controller plate may partially return to neutral position, thus freeing the roll 43. These movements take place while the needle ofthe sewing mechanism is adthe work, and before the awl and channel guide have returned to their initial position. The bell crank lever 42 is then actuated by its cam to retract the feeler so that the feeding awl and channel guide may be retracted preparatory to the next feed. and the channel guide may engage the channel at substantiallythe point which was engaged by the feeler. During the return movement of the awl and channel guide, the actuating lever 5T is rocked by its crm to operate the driving member 66 of the jack swinging clutch, so that the swinging movement of the shoe takes place while the needle is still in the stock.

51. The clamp During the feed of the shoe the'jaclr swinging clutch is disengaged, and the actuating lever is returned and the actuso that the feeler finger1` to retracted position, the clamp 86 being released so that the plate 44 may be returned to its retracted position. As the feed of the shoe is completed, and the awl and channel guide are disengaged from the channel, the cam 42 releases the bell crank lever 42, so that the feeler is again advanced and engages the channel, preparatory to the next cycle of operations. Thus during each cycle of operations the feeler engages the channel at a point in advance of the needle substantially equal to each feeding movement of the shoe and sets the jack swinging mechanism, so that this point in the channel is swung into the line of feed where it will be properly engaged by the channel guide and awl.

ln sewing shoes having substantially flat soles, the shoe may be maintained in proper relation to the sewing mechanism by the swinging movements imparted to the shoe. To insure the proper engagement of the channel guide with the base of the channel in sewing shoes the soles of which have a moderate longitudinal curvature, it may be found desirable to mount the channel guide and awl upon the vfeed slide in such manner that they may move vertically to accommodate themselves to the vertical position of the surface of the sole, and to provide centering levers 93 and cams 94 for bringing the channel guide and awl into proper vertical relation to the needle previous to the passage of the needle through the stock, as is more fully explained in Patent No. 1,03(), 0423, June 18, 1912.

In order to relieve the needle or other device of the sewing mechanism from the strain to which they would otherwise be subjected during the swinging of the jack, additional devices are provided for constraining the jack to swing'about the point of operaj the yolze i l l tion of the sewing devices. 1n the construction shown these devices consist of a clamp, the

jaws

95 and 96 of which are arranged to grip a plate 97. The plate 97 is secured to 10 so that it turns with the jack and has an outline corresponding generally to the shape of a shoe sole, so that the marginal portion of the plate may travel between the jaws of the gripper as the jack is mover longitudinally and swung during the sew* ing operation. The jaws of the clamp are so arranged that a line passing through the ioint of operation ofthe sewing mechanism, and parallel with the axis of the jack turn- S, will pass through the axis of the jaws. lVhen the clamp is engaged with the plate, therefore, it will form a pivot about which the 'jack will swing when the jaclr turning shaft is rotated, and as this pivot is in line with the point efcperatien of the sewing mechanism, the cla "p constrain the jaclr to swing about of operation, and will relieve tl Y .Y which the needle would other.

ing sha-ft on the jaw jected. The jaws of the pivot clamp are p rovided with studs -98 for engaging the opposite sides of the plate, and these studs are so mountedlthat they may turn freely in the jaws of the gripper as the jack and plate 97 swing. The movable gripper jaw 9G is actuated to intermittently engage the gripper with the plate 97 by a cam 99 arranged to `engage a. lever 100 which is pivoted on the gripper jaw and transmits a gripping pressure to the jaw through a spring similar to the spring 101 shown in Fig. 13.

I'ln order to assist the awl in feeding the shoe, or to relieve it ofthe strain incident to overcoming the inertia and friction of the jack supporting devices, a supplemental feeding 'mechanism is provided forimparting feeding movements to the jack in unison with the feeding movements of the awl. As shown, the supplemental feeding devices consist of a feeding gripper arranged to act on the plate 97. The feeding gripper comprises an arm 102 pivotally mounted in a bracket 103, and provided at its forward .end with a freely turning'stud 104i for engaging the under side of the plate 97. The movable jaw 105 of the feeding gripper is pivoted on .the plate 102, and is provided with a pivoted gripping stud 106 at its forward end. `The jaw 105 is actuated to intermittently grip the plate 97 by a cam 107 arrangedito engage the end of a lever 108 which is pivoted 105 and imparts a clalnping pressure to the jaw'through the spring 101 above referred to. The feeding gripper is actuated to impart feeding movements toithe` plate 97 and connected jack through an arm 109 which projects from the hub ofthe .arm 102 and is connected by a, link 110 with one armY of a bell crank lever 111. The other arm of the bell crank lever carries a roll which is held in engagement with a cam 112 by a spring 113. The link 110 is adjustahly connected to the arm of the bell crank lever 111, so that the feeding movement of the gripper may be adjusted to correspond to the feeding movement imparted to the shoe by the feeding awl. In order that the operator may disengage both the feeding and pivot grippers from the plate, in case either of them are gripping the plate when it is desired to swing the jack out of position, the

movable jaws 96 and 105-are' extended rearwardly into position to be engaged by a cam 114 formed on the upper end of a stud 115. This cam is provided with an operating handle 110 through which it may be turned to depress the rear ends of the movable gripper jaws and thus disengage the front ends of the jaws from the plate 97.

The cams for actuating the pivot and feeding gripper-s are secured on a shaft 117 which is continuously driven andmakes one revolution for each revolution of the cam shaft of the sewing mechanism. The cam 99 is so timed that the pivot gripper is engaged with the plate 97 when the correcting mechanism is operated to swing the` jack, and is disengaged from the plate at other times. The

cams

107 and 112 are so timed that the feeding' gripper engages and'feeds the forward plate during the feeding movement of the awl, and is disengaged from the plate and returned to initialposition during the return of the feeding awl.

The various mechanisms of the machine are driven from a main driving shaft 118 through a suitable form of clutch which is under -the control of the operator. The driving shaft is connected through a chain 119 with a shaft 120. The cam shaft 121 of the sewing mechanism is driven from the shaft 120 through beveled gearing and a shaft 122. ,f The cam shaft 117 is driven from the shaft 120 through the

chains

123, 124 and 125, and the cam shaft 48 for the correcting mechanism is driven through the

chains

123 and 126, the connections being such that the cam shafts L18 and 117 each make one revolution for each revolution of the cam shaft 121.

While` the invention has been illustrated and explained in connection with its application to mechanism for swinging the shoe during the operation thereon of inseam sewing me'chanism, and certain features of the invention relate more particularly to such a machine and mechanism, it will be understood that the broader features of the invention may' be embodied in machines for performing other operations upon a shoe, or in mechanisms for otherwise correcting the relative position of the shoe and means for operating thereon during the transfer of the pqint of operation of the operating means 'around the shoe to maintain the shoe and operating means in proper relation. It will also be understood that the specific construction and arrangement of the parts is not material to the broader features of the invention, and may be varied and modified to suit the type of machine in which the inventien is embodied, and the -character of the corrective movements which are to be effected, without departing from the in vention.
