Definitions

  • This invention relates to lasting machines having means for shaping an upper over a last and means for fastening the upper in lasted relation to an insole or other shoe bottom part (hereinafter frequently referred to generically as the although it will be understood that in various novel aspects the invention is not limited to machines of that particular type. It is to be understood also that in some aspects the invention is not limited to machines having means for driving fastenings.
  • Machines of the type disclosed in the abovementioned Letters Patent include in their organization means for pulling an upper over a last successively in diiferent locations as the shoe is presented in different positions by the operator, and fastening-inserting mechanism comprising a staple-guiding nozzle movable inwardly over the bottom of the shoe to lay the marginal portion of the upper over the outer face of the sole, a driver for driving staples through said nozzle to fasten the upper to the sole, and a deflector for curving the legs of each staple prior to and during their entrance into the shoe to anchor them in the shoe.
  • the present invention provides a novel organization including an overlaying device movable relatively to the fastening-inserting mechanism at the will of the operator into position to engage and wipe the marginal portion of the upper inwardly over the outer face of the sole while moving with the fastening-inserting mechanism over the bottom of the shoe in lasting with cement instead of driven fastenings, and means for operating the overlaying device by impact to force the overwiped' margin of the upper into firm adherence to the sole.
  • the fastening-inserting mechanism is moved inwardly over the bottom of the shoe as heretofore in a direction somewhat inclined toward the shoe bottom, after which it is moved, also as heretofore, toward the bottom face of the shoe in a direction substantially at right angles to the direction of its inward movement to insure that it will be close to the shoe bottom prior to the insertion of each fastening; and when the above-mentioned overlaying device is in use it receives corresponding movements.
  • the fastenings are inserted by a driver which is operated by mechanism arranged, in the construction herein shown, also to operate a hammer for delivering a blow to the abovementioned overlaying device when the over- 5 laying device is in position for use in lasting with cement.
  • the present invention accordingly provides an overlaying device movable inwardly over the bottom of the shoe to lay or wipe the marginal portion of the upper over the outer face of the sole and then in a different direction toward the shoe to increase its pressure on the overwiped margin of the upper, after which its pressure is further increased substantially at the end of its second movement toward the shoe.
  • the upper is, therefore, wiped tightly inward over the sole and is thereafter pressed with substantial firmness upon the outer face of the sole before the delivery of the blow by the hammer to insure firm adhesion of the cemented engaging faces of the upper and the sole.
  • Novel means is also provided for operating the driver for the fastenings in a retracted position so that it will not hit the staple deflector when the overlaying device is in use.
  • the driver is operated by a lever which in turn is operated by a second spring-operated lever.
  • the first lever is mounted on an eccentric which is connected to the overlaying device and is rotatable in response to movement of the overlaying device into or out of position for use to adjust the position of the first lever relatively to the second springoperated lever to vary the extent of movement of the driver toward the deflector.
  • Machines of the type illustrated are provided with a shoe bottom rest, and a side gage arranged to engage the shoe substantially opposite the edge of the sole to determine the position of the shoe laterally and in cooperation with the bottom rest to determine the angular relation of its bottom face to the direction of forward movement of the fastening-inserting mechanism over the shoe.
  • the shoe should be positioned with its bottom face in such angular relation to the direction of forward movement of the fastening-inserting mechanism as to provide a small amount of clearance between the fastening-inserting mechanism and the extreme edge of the shoe bottom as the fastening-inserting mechanism moves inwardly over the shoe.
  • an inward wipe may be applied to the upper substantially from the edge of the shoe bottom, as is desirable in lasting with cement, without varying substantially the angle at which the bottom face of the shoe is presented.
  • the position of the shoe laterally is usually such that the staples are inserted substantially midway between the edge of the shoe bottom and the edge of the overlaid margin of the upper.
  • the margin of the upper for best results should be wiped inwardly over the shoe bottom for substantially its entire width.
  • the position of the shoe laterally should be altered in lasting with cement to permit the overlaying device to move farther inwardly over the sole for that purpose.
  • Any rearward adjustment of the side gage widthwise of the shoe necessitates a some-' what higher position of the gage, by reason of the angle at which the shoe is presented, if the angle is to remain substantially the same.
  • the machine is accordingly provided with novel means for adjusting the side gage, the construction shown comprising means for adjusting the gage bothwidthwise and heightwise of the shoe into different positions for lasting with cement or with staples respectively, this adjustment of the gage being effected, as illustrated, by the same means that moves the overlaying device into and out of position for use.

42 Claims.
This invention relates to lasting machines having means for shaping an upper over a last and means for fastening the upper in lasted relation to an insole or other shoe bottom part (hereinafter frequently referred to generically as the although it will be understood that in various novel aspects the invention is not limited to machines of that particular type. It is to be understood also that in some aspects the invention is not limited to machines having means for driving fastenings.
Machines of the type disclosed in the abovementioned Letters Patent include in their organization means for pulling an upper over a last successively in diiferent locations as the shoe is presented in different positions by the operator, and fastening-inserting mechanism comprising a staple-guiding nozzle movable inwardly over the bottom of the shoe to lay the marginal portion of the upper over the outer face of the sole, a driver for driving staples through said nozzle to fasten the upper to the sole, and a deflector for curving the legs of each staple prior to and during their entrance into the shoe to anchor them in the shoe. The present invention provides a novel organization including an overlaying device movable relatively to the fastening-inserting mechanism at the will of the operator into position to engage and wipe the marginal portion of the upper inwardly over the outer face of the sole while moving with the fastening-inserting mechanism over the bottom of the shoe in lasting with cement instead of driven fastenings, and means for operating the overlaying device by impact to force the overwiped' margin of the upper into firm adherence to the sole. In the machine illustrated the fastening-inserting mechanism is moved inwardly over the bottom of the shoe as heretofore in a direction somewhat inclined toward the shoe bottom, after which it is moved, also as heretofore, toward the bottom face of the shoe in a direction substantially at right angles to the direction of its inward movement to insure that it will be close to the shoe bottom prior to the insertion of each fastening; and when the above-mentioned overlaying device is in use it receives corresponding movements. The fastenings are inserted by a driver which is operated by mechanism arranged, in the construction herein shown, also to operate a hammer for delivering a blow to the abovementioned overlaying device when the over- 5 laying device is in position for use in lasting with cement. The present invention, in one important aspect, accordingly provides an overlaying device movable inwardly over the bottom of the shoe to lay or wipe the marginal portion of the upper over the outer face of the sole and then in a different direction toward the shoe to increase its pressure on the overwiped margin of the upper, after which its pressure is further increased substantially at the end of its second movement toward the shoe. The upper is, therefore, wiped tightly inward over the sole and is thereafter pressed with substantial firmness upon the outer face of the sole before the delivery of the blow by the hammer to insure firm adhesion of the cemented engaging faces of the upper and the sole.
Novel means is also provided for operating the driver for the fastenings in a retracted position so that it will not hit the staple deflector when the overlaying device is in use. As herein shown, the driver is operated by a lever which in turn is operated by a second spring-operated lever. The first lever is mounted on an eccentric which is connected to the overlaying device and is rotatable in response to movement of the overlaying device into or out of position for use to adjust the position of the first lever relatively to the second springoperated lever to vary the extent of movement of the driver toward the deflector.
Machines of the type illustrated are provided with a shoe bottom rest, and a side gage arranged to engage the shoe substantially opposite the edge of the sole to determine the position of the shoe laterally and in cooperation with the bottom rest to determine the angular relation of its bottom face to the direction of forward movement of the fastening-inserting mechanism over the shoe. Preferably the shoe should be positioned with its bottom face in such angular relation to the direction of forward movement of the fastening-inserting mechanism as to provide a small amount of clearance between the fastening-inserting mechanism and the extreme edge of the shoe bottom as the fastening-inserting mechanism moves inwardly over the shoe. By providing the overlaying device, as herein illustrated, with a wiping portion between the staple nozzle and the shoe bottom, it will be seen that with the overlaying device in position for use an inward wipe may be applied to the upper substantially from the edge of the shoe bottom, as is desirable in lasting with cement, without varying substantially the angle at which the bottom face of the shoe is presented. In lasting with staples the position of the shoe laterally is usually such that the staples are inserted substantially midway between the edge of the shoe bottom and the edge of the overlaid margin of the upper. In lasting with cement, however, the margin of the upper for best results should be wiped inwardly over the shoe bottom for substantially its entire width. It will accordingly be seen that the position of the shoe laterally should be altered in lasting with cement to permit the overlaying device to move farther inwardly over the sole for that purpose. Any rearward adjustment of the side gage widthwise of the shoe, however, necessitates a some-' what higher position of the gage, by reason of the angle at which the shoe is presented, if the angle is to remain substantially the same. The machine is accordingly provided with novel means for adjusting the side gage, the construction shown comprising means for adjusting the gage bothwidthwise and heightwise of the shoe into different positions for lasting with cement or with staples respectively, this adjustment of the gage being effected, as illustrated, by the same means that moves the overlaying device into and out of position for use.
The above and further features of the invention, including novel means for elevating the hammer in the return of the parts to starting positions and various novel details of construction and combinations of parts, will now be more particularly described by reference to the accompanying drawings and pointed out in the claims.

vention will be described herein in detail. 5
It will be understood that the shoe on its last is supported in the hands of the operator and is presented successively in different positions in the progressive lasting of its opposite sides. To assist in determining the proper relation of the 10 shoe to the lasting instrumentalities the machine is provided with a side gage ll] arranged to engage the side of the shoe at or near the edge of the sole and with a shoe bottom rest [2 arranged to The upper is 15 pulled over the last and the sole when the shoe is in each lasting position by a gripper comprising a pair of gripper jaws I4. For laying the marginal portion of the upper inwardly over the sole and fastening it with staples, there is provided a slide or carrier it? (Fig. 1) which is movable along a guideway 58, formed on a member It, in a forwardly and downwardly inclined direction toward the bottom of the shoe. For moving the slide it along its guideway toward and from the shoe, there is formed in one side of a cam wheel 20 fast on a shaft 22 mounted in suitable bearings in the head of the machine, a path cam 2d (Fig. llwhich engages a roll 26 on the slide. This slide carries a staple guide-or nozzle 30 23, a staple driver 3% and a deflector 32 the lower end of which occupies a position opposite to the end of the staple-guiding passage in the nozzle 28 for engaging the legs of the staples and curving them prior to and during their entrance into the 35 shoe so that they are anchored in the sole without necessarily emerging from its inner face, as illustrated in Fig. 2. The operative movement of the driver is in a rearward direction and the deflector curves the legs of the staple forwardly away from the edge of the sole. It will be understood that in the forward movement of the slide l6 prior to the driving of the staple the nozzle 28 and the deflector 32 act as overlaying means to lay the upper over the outer face of the sole.
The staple driver 39 is fastened to a driver slide 3t which is movable in a guideway formed in a bracket 36 secured to a forward extension of the slide it. The driver slide 34 is operated by a lever 38 which is'pivoted on a stud 40 on a forward extension of the slide 35 and carries a lug 52 which extends into a recess in the driver slide 34. The lever 38 is operated by a bell-crank lever 44 which is pivoted on a rod 46 on the slide 16 and is operated in turn by a torsion spring 48 (Fig. 4). A forwardly extending arm 45 of thebell-crank lever 4 carries a roll 5d (Fig. l) which operates in a cam slot 52 in the lever 38, the cam slot being so formed that staple-driving movement is imparted to the lever 38 by upward movement of this arm. For swinging the bell-crank lever 44 against the resistance of the spring 48 to retract the driver 3% and to tension the spring, there is pivoted at as on the head of the machine a lever 56 on which is pivotally mounted at 58 a latch 60 arranged to engage the lower end of a plate 62 fast on a downwardly extending arm of the bell-crank lever 44. A spring 64 connected to the latch 60 and to a pin on the lever 53 holds the latch in engagement with the plate 62 when the slide l6 and the parts carried thereby are in their initial positions. When the slide is moved forwardly toward the shoe, the latch til acts to swing the bell-crank lever .4, against the resistance of the spring 48, in response to such forward movement, thereby 7 retracting the staple driver 30 as the latter is being carried bodily forward by the slide. For operating the latch 68 to release the lever 44 and thus to cause the operation ,of the driver, the slide It carries a screw 5% the head of which is arranged to engage a shoulder on the latch, as illustrated in Fig. l. The forward movement of the slide It, however, does not carry the screw far enough to release the lever 44, such release being effected in response to a swinging movement of the latch-carrying lever 56 after the slide I6 has completed its forward movement. For imparting to the latch-carrying lever its swinging movement there is provided in one side of the cam wheel 2o (Fig. l) a path cam 68 which engages a roll 69 carried by the lever 5%. It will be understood that by reason of such movement of the lever 56 the screw 56 causes the latch 60 to swing far enough to: disconnect it from the plate 62. 20
In the return of the parts to starting positions the latch 62 is held by a shoulder 70 on the lever 56 in position to connect again with the plate 62.
The machine is also provided with means for forming a staple in response to the forward move ment of the slide IS and for thereafter transferring the staple from forming position into alinement with the driver. I6 carries an inside form'er 72 (Fig. 7) arranged to cooperate with a stationary outside former M. 30'
Wire for forming the staples is f d automatically into position to be operated upon by the inside and outside formers through a nozzle 76 which is carried by the slide 26, this nozzle cooperating with a stationary shearing plate 18 to cut the wire. After the staple has been formed it is transferred downwardly into the path of movement of the driver by a transferring member 80 which operates bet een the inside and outside formers, this member being carried by a slide 82 (Fig. 1) movable in a guideway provided on the slide I and operated at the proper time by mechanism including a link 84.
The means for feeding the staple wire is substantialy like that shown and described in Letters Patent of the United States No. 1,795,451, granted March 17, 1931, on an application of George Goddu. The wire is mounted on a reel (not shown) and is operated upon by feed wheels 85, 88 (Fig. 4) from which it is conducted through a flexible tube 99 to the nozzle 25. The feed wheel 85 is operated by a pawl and ratchet mechanism through a link 92 and a bell-crank lever 94 provided with a roll 96 engaged by a cam I00. In order to stop the feed of the wire when desired there is provided a lever 82 having thereon a projection Hi4 arranged to engage a face I66 on the lever 95 and thus to hold this lever in such a position as to prevent it from being operated by the cam Hill.
The machine is further provided with means for imparting to the overlaying and fastening mechanism after it has been moved inwardly over the shoe bottom a movement in a different direction toward the bottom face of the sole to insure that it will be close to the shoe bottom immediately before the staple is driven. For this purpose the member i9 which provides a guideway for the slide it is secured by screws I 88 (Fig. 1) to a holder llil which has a downwardly extending portion fast on a rockshaft H2 mounted in the head of the machine. Secured also on the rockshaft H2 is a lever l M carrying a roll I Hi engaged by a path cam 5 is formed in one side of a cam-wheel I23 on the cam shaft 22. It will thus be seen that by the action of the cam II8 For this purpose the slide on the lever H4 the slide I6 and the fastening mechanism carried thereby are swung downwardly toward the bottom of the shoe in a direction substantially at right angles to the direction of their movement inwardly over the shoe. After 5 driving the staple, the staple driver 30 remains at the end of its driving movement and the cam H8 is so shaped, as illustrated in Fig. I, as to impart to the slide It, immediately after the staple-driving operation and prior to the retrac- 10 tive movement of the slide along its inclined guideway, a reverse upward swinging movement which is of somewhat greater extend than the extent of its downward swinging movement prior to the driving of the staple. tion to the retractive movement of the slide I6 effected by the cam 2d, the cam H8 swings the slide back to a normal position preparatory to operations on the next shoe.
In order that the machine herein shown may be adapted to last a shoe, or a portion thereof, with cement instead of with staples, there is provided an overlaying device mounted upon the slide or carrier I 6 and movable at the will of the operator into a position immediately below the staple nozzle and deflector to act as a wiper to wipe the marginal portion of the upper inwardly over the sole. This overlaying device comprises a member I22 secured to a second member I23 (Figs. 2, 3 and 11) pivotally connected to a slide i226 mounted in a guideway formed in a bracket fast on the slide I6. The member I22 extends forwardly (Figs. 2, 3 and 5) and has a relatively thin blade portion I25 at its forward end provided with a flat Wiping face I21 which 85 is arranged to engage the upper over a greater extent lengthwise of the edge of the shoe bottom than the staple guide 28 and deflector 32. The member I23 carries an adjusting screw I29 which is held in engagement with a shoulder I3I on the slide I24 by a compression spring I 33 extending between the slide 124 and the member I23. It will be evident that by adjustment of the screw I 29 the member I 22 maybeswung relatively to the slide I 24 to vary the position of its wiping face heightwise of the shoe, the screw I29 being preferably so adjusted that the overlaying member will be positioned with its wiping face substantially in parallel relation to the path of movement of the slide I6 along its guideway I8. controlled by a lever I 28 pivotally connected to the bracket I25 and provided with an inwardly extending arm I 30 (Figs. 5, 8 and 10) arranged to engage one or the other of a pair of pins I32, 34 carried by the slide I24 and extending upwardlythrough a slot I36 in the bracket I26, the construction being such that by swinging the lever I28 a forward movement may be imparted to the slide I24 to position the overlaying member I22 directly under the staple guide or nozzle 00 2t and the deflector 32 for wiping the upper inwardly over the sole while moving with the guide and deflector, as illustrated in Fig. 3, or a rearward movement may be imparted to the slide to move the overlaying member into a retracted 55 position to permit the lasting of the shoe with staples, as illustrated in Fig. 2. The length of the arm I36 is such that as the slide I 24 cornpletes either its forward or rearward movement a further swinging movement may be imparted to the lever I28 to move the arm I 30 relatively to the pin through which such movement was imparted to the slide into a position to lock the slide against movement in the opposite direction. By reference to Figs. 8 and 10, it will be seen that Thereafter, in time rela- 16' The slide I24 is 5 when the overlaying member is in its forward position the pin I34 engages the bracket I26 at the forward end of the slot I36 and that the overlaying member is locked against rearward movement in response to pressure of the shoe against it by the engagement of the arm I36 with the pin I34. For imparting to the lever I28 its swinging movements, there is provided a hand lever I38 (Figs. 2, 3, 8 and 9) pivotally connected at $49 to a laterally extending arm I42 of a bracket I44 secured to the head of the machine. The hand'lever I38 has a forwardly extending arm I46 to which there is connected by a ball and socket connection a rod I48 having adjustably fastened thereon a pair of collars I56 arranged to serve as abutments engaged by a stud I52 through which the rod I48 extends, the stud being pivotally connected to a downwardly extending arm I54 of the lever I28.
When the hand lever I38 is swung forwardly from the position shown in Fig. 8, the lever I28 is swung in a direction to move the arm 5% rearwardly. As the arm I36 moves rearwardly it engages the pin E32 and moves the overlaying member I22 rearwardly to an idle position, after which the arm I36 moves relatively to the pin I32 into a position to lock the slide I24 and the overlaying member against forward movement. To hold the hand lever I 38 against movement relatively to the fixed arm I42 with the overlaying member either in a forward position for use as a wiper or in a retracted or inoperative position, there is provided a spring-pressed detent I56 carried by the lever I38 and arranged to engage one or the other of a pair of recesses Hit formed in the arm I42. When it is desired to move the overlaying member I22 forwardly into position to act as a wiper the hand lever I 38 is swung rearwardly relatively to the arm I42 into the position shown in Fig. 8, and in order that the feeding of the wire will be interrupted so that no staple will be formed when the overlaying member is in position for use there is pivotally connected to a rearwardly extending arm I62 of the lever I38 a rod I64 extending through a recess in a stud I65 pivotally connected to the lever m2 and having fast thereon collars I68 arranged to engage the stud. When the hand lever 33, therefore, is swung rearwardly the lever I52 is swung to the eft, to the position shown in Fig. l, to interrupt the feeding of the staple wire.
In order to insure adequate adhesion of the overlaid margin of the upper and the sole when lasting the shoe with cement, the illustratedmachine is provided with means for imparting to the overlaying device at the completion of its overlaying movement a hammer blow to cause the overlaying device to force the upper by impact against the bottom face of the sole. By reference to Figs. 2, 3 and 11 it will be seen that the member I23 to which the overlaying member I22 is secured has an upwardly extending arm I16. The upwardly extending arm lit has a head I86 which, when the overlaying member is'in its forward position, is beneath a hammer I88.- The hammer is operated at a proper time in the cycle of the machine by a lever I6?! which is pivoted on the stud 4t! and has an upwardly extending arm I92 in which there is formed a camslot I64 engaging a roll I96 carried by the forwardly extending arm 45 of the bell-crank lever 44 (Figs. 1, 2, 3 and 4). The cam slot m4 is so formed that, as the arm 45 moves upwardly the hammer I88 is swung in a direction to strike the arm I16 of the member I253. It will be understood that the upward movement of the arm 45 takes place after the slide I6 has completed its forward movement along the inclined guideway I8 and substantially at the time when the swinging movements of the holder III] and the slide I6 about the axis of the rockshaft H2 in a direction to move the overlaying member downwardly, have been completed. The overlaying member is thus moved inwardly over the shoe bottom to wipe the marginal portion of the upper inwardly over the sole, after which the overlaying member is moved in a different direction toward the shoe to increase its pressure on the overlaid margin of the upper before the blow is delivered to cause it to force the margin of the upper by impact against the sole to secure firm adhesion between the cemented engaging faces of the upper and the sole. The pressure of the overlaying device on the upper is then relieved by the upward swinging movement of the holder He and the slide it? about the axis of the rockshaft III: before the overlaying device is moved rearwardly from over the shoe, thus eliminating any possibility of such outward drag of the overlaying device on the margin of the upper as would tend to displace the upper from lasted position. The hammer I38 is adjustably secured to a laterally extending arm Hit of the lever I (Figs. 2 and 3). The hammer has a threaded upper portion 2% extending through a split bearing formed in the outer end of the arm I98 and a lower portion recessed to receive a fiber washer which is arranged to engage the head I8 5 of the arm HG. It will be seen that by rotating the hammer in the bearing its position heightwise or" the arm I98 may be varied so as to vary the force of the blow delivered to the overlaying member, a binding screw 2% being provided for drawing the two parts of the split bearing together to hold the hammer in adjusted position.
In order to prevent the driver 39 from striking the deflector in the upward movement of the arm 45 when the overlaying member I22 is in position for use, there is provided means operative in response to forward movement of the slide E24 for shifting the position of the slide 34 in its guideway in the bracket 36 to vary the limit of movement of the driver toward the deflee-tor. As shown particularly in Fig. 6, there is provided between the stud as and the levers t8 and Ii l a sleeve 2B8 having a portion 2H] upon which the lever i is mounted, which portion is concentric with the axis of the stud 40, and a portion 2E2 eccentric to the axis of the stud and upon which the lever 38 is mounted. The sleeve is rotatably mounted on the stud and has a depending arm 2H5 (Figs. 2 and 3) at its outer end connected by a link M6 to the upwardly extending arm I16 of the member I23 which is carried by the slide I24. Thus as the slide I24 and the member I23 are moved forwardly by rearward movement of the hand lever I32, the sleeve is rotated on the stud 40 and by reason of the eccentricity of the portion 2I2 of the sleeve, a swinging movement is imparted to the lever 38 about the axis of the roll 50 in a direction to impart to the slide 34, through the lug 42, a movement to the left (Figs. 2 and 3) to retract the driver. The driver is thus operated in a retracted position, when the overlaying device is in use, so that any danger of damaging the driver or the deflector, by interference between these parts, is avoided.
In the illustrated machine theposition of the shoe laterally is determined by the side gage Ill which is arranged to engage the shoe substantially opposite the edge of the sole, the position of the shoe heightwise in the machine being determined by the rest #2. Preferably the gage ill and the rest l2 are so adjusted that, with the gage engaging the shoe in the location above described the shoe may be presented with its bottom face in such angular relation to the direction of forward movement of the stapling mechanism and in such heightwise relation to the stapling mechanism as to provide a small amount of clearance between the stapling mechanism and the extreme edge of the shoe bottom in the movement of the stapling mechanism over the shoe. Since the relatively thin blade portion i235 of the overlaying member I22 is directly beneath the stapling mechanism when the overlaying member is in position for use it will be evident that as the overlaying member moves inwardly over the shoe with the stapling mechanism it tends to engage the upper initially nearer the edge of the shoe bottom than the stapling mechanism and thus may wipe the margin of the upper inwardly substantially from the edge of the insole, as is desirable in lasting with cement. In lasting shoes with cement, however, the margin of the upper should preferably be wiped inwardly over the sole for substantially its entire width and, since the fastenings are inserted substantially midway between the edge of the shoe bottom and the edge of the overlaid margin of the upper in lasting the shoe with staples, the position of the shoe laterally should preferably be altered in lasting with cement in order to permit the overlaying member to move farther inwardly over the shoe bottom for that purpose. Any adjustment of the side gage rearwardly, however, to vary the position of the shoe laterally and thereby to vary the extent of inward movement of the overlaying member, necessitates a somewhat higher position of the gage by reason of the angle at which the bottom face of the shoe is presented, which should be substantially the same in lasting with cement as in lasting with staples. Accordingly, the illustrated machine is provided with means for adjusting the side gage I!) both widthwise and heightwise of the shoe to vary the position of the shoe laterally and to control the angular relation of its bottom face to the direction of forward movement of the stapling mechanism and the path of movement of the overlaying member over the shoe.
For the purpose in view the gage i0 is pivoted at 222 on a slide 222 which is adjustable horizontally along a guideway 224 (Figs. 1, 8 and 9) in the bracket l i l to vary the position of the gage IE relatively to the rest l2 laterally of the shoe. The gage It; has a rearwardly extending portion 226 (Fig. 1) in which there is formed a slot 228 and extending into the slot is a pin 22E} projecting from the bracket Hi l. The slot 223 (Fig. 1) is disposed at an angle to the horizontal so that as the slide 222 is moved rearwardly in its guideway 224, the gage ill is swung about its pivot 226 in a direction to move its shoe engaging end upwardly and as the slide 222 is moved forwardly the gage is swung in a direction to lower its shoe engaging end, the inclination of the slot 228 being such that as the slide 222 is adjusted in its guideway 22 the shoe engaging end of the gage It is moved away from or toward the rest H2 in a predetermined inclined path. The gage may accordingly be adjusted. to vary the position of the shoe laterally without varying the angular relation of its shoe engaging end and the rest 12. The shoe may thus be presented with its bottom face in substantially the same angular relation to the direction of movement of the difierent lasting instrumentalities oi the machine in all adjusted positions of the gage to vary the position of the shoe provided with a lengthwise slot 232 (Figs. 1, 8
and 9) to receive a block 232 which is held against movement relatively to the slide by a clamping screw 2%. The block 23 has a transverse slot 233 (Fig. l) and. projecting into the slot is a pin 22% carried by one arm of a bell crank lever 222 pivoted at 244 to a rearwardly extending portion 246 of the bracket 1 4:2. The bell-crank lever 2 32 has a second arm 228 carrying a pin 25!! which extends into a slot 252 formed in a link 254 pivotally connected to an arm 25% of the hand lever I38. The slide 222 is supported in its guideway 222 by a cover plate 258 (Fig. 1) secured to the bracket I42, and carried by the cover plate is a pin 262 (Fig. 3) which projects upwardly into a recess 262 formed in the under side of the slide 222. Mounted in the recess 252 between the pin 260 and a shoulder 264 formed on the slide 222 is a compression spring 266 which acts to move the slide 222 rearwardly and to hold it with a shoulder 26% on the slide in engagement with an adjustable stop, herein illustrated as a screw 216, carried by the cover plate 258. When the slide 222 and the gage it are in their rearward positions (Fig. 3) the overlaying member I22 is in position for use and the hand lever l 38 is in the position indicated in Fig. 8. By reason of the pin and slot connection between the arm 228 of the be1l-crank lever 242 and the link 2254 it will be readily seen that by movement of the screw 215) the gage It) may be adjusted toward or from the rest l2 to vary the position of the shoe laterally andthereby to vary the extent of inward movement of the overlaying member as may be necessary to take care of variations in the width of the lasting margins of the uppers of diilerent shoes. It will be evident that with the parts in the positions shown in Fig. 3 rearward movement of the gage ID is prevented by engagement of the shoulder 268 with the screw 270, the screw being held in adjusted position by means of a lock nut 212. By reference to Figs. 8 and 9 it will be seen that, as the hand lever I38 is swung forwardly from the position shown in Fig. 8 to the position shown in Fig. 9 to move the overlaying member I22 rearwardly to an idle position, the arm 256 of the lever I38 will be swung rearwardly thereby moving the link 254 from an inclined position into a substantially horizontal position. This movement of the link 254 acts through the pin 250 to impart to the bell-crank lever 242 a swinging with the link 254 at the right-hand end of the slot 252.
In order that the position of the shoe laterally adjusted position.
justing the side gage Ii) toward or from the shoe rest I2 when the gage is in its forward position.
'As previously pointed out, the block 234 and the slide 222 are held against relative movement by a clamping screw 236.
The screw 236, which is threaded in the block 234, extends upwardly through a slot 214 in the slide 222, and has a collar 216 bearing against the bottom face of the slide. After loosening the screw 235 the slide 222 may be moved either forwardly or rearwardly in its guideway 224 to move the gage I'Il toward or from the rest I2 after which the screw 236 may be tightened to hold the block and slide against relative movement with the gage in its It Will be understood that as the slide 222 is adjusted in its guideway to vary the forward position of the gage II] the gage is also swung about its pivot 229 by reason of the engagement of the pin 2% with the gage in the slot 238 so that its shoe-engaging end moves toward or from the shoe rest I2 in a predeterrnin'ed inclined path thus maintaining it at all times in the same angular relation to the shoe rest I2.
'When the machine is initially at rest the slide IB is in its retracted position, and in order that the hand lever I38 may be swung, by the operator, at that time either forwardly to set the machine to last the shoe with staples, or rearwardly to'move the overlaying member I22 into position for use in lasting the shoe with cement, without interference between the hammer I88 and the'arm I16 of the member I23, the illustrated machine is provided with means for imparting to the lever 44 a movement in a direction to raise the hammer I28 enough to clear 'the arm I16 in the return of the parts to starting positions. As shown particularly in Figs. 1 and 3, the lever 44 has an upwardly extending arm 218 which is arranged near the end of the retractive movement of the slide I6 along its guideway I8 toengage a roll 289 mounted on an eccentric stud 282 secured to the head of the machine. Thereafter as the slide I6 continues its retractive movement toward starting position the bell-crank lever 44 is swung, in response to the "action of the roll 28!] on the arm 218, in a direction to lower the arm 45 and to move the plate 62 toward the latch 65, the arrangement of the parts being such that as the slide I6 completes its retractive movement sufficient swinging movement is imparted to the lever 44 'to' move the plate 62' into position to connect with the latch BI! which is made somewhat shorter than heretofore in machines of the illustrated type. The downward movement of the arm 45 acts to swing the lever I99 in a direction to raise the hammer I88. It will thus be seen that there will be no frictional drag of the hammer on the head I86 of the arm I16 as the hand lever I38 is swung about its pivot by the operator either rearwardly to move the arm I15 beneath the hammer I83 or forwardly to move the arm I16 from beneath the hammer I88, It will be understood that for convenience the roll 280 is mounted on the eccentric stud 282 which may be adjusted .to vary the position of the roll and thus to vary the time in the retractive movement of the slide I6 when the arm 218 engages the roll. Thus the amount of swinging movement imparted to the lever 44 may be: va-
ried to insure that the plate 62 will be swung far enough to connect with the latch by the time when the slide I6 completes its retractive movement.
