23 Claims.

The present invention relates to machines for use in the manufacture of shoes, and more particularly to an improved jack for supporting a shoe in a machine, of the type in which the shoe and the means for operating on the shoe are automatically moved relatively to transfer the point of operation along the shoe and in which the relative position of the shoe and the operating means is automatically changed as the point of operation is transferred along the shoe topresent the shoe properly to the operating means.

In machines of the type above referred to, the position of the shoe during theoperation thereon is controlled by mechanism acting on the jack and imparting to the jack at predetermined times during the operation, movements predetermined as to direction and extent. Such predetermined movements are imparted to the jack not only during the principal operation on the shoe as, for instance, the inseam sewing operation, but also after the principal operation has been finished, to position the shoe for an auxiliary operation or operations and to move the shoe away from the operating devices and return it to its original position. For the successful operation of these machines it is necessary that the shoe to be operated upon be located accurately in predetermined position with relation to the jack and, for this reason, and on account of the uniform and predetermined movements necessarily imparted to the jack, it has been considered necessaryhere tofore to supply specially: prepared lasts for use in the machines, having certain of their dimensions uniform and predetermined, particularly as to the height of the last andthe location of the pin hole for receiving the last pin of the jack.

Ordinary commercial lasts vary considerably in the location and-depth of the spindle hole. and also vary in depth and in other particulars so that their use heretofore in machines of the type above referred to, has been unsatisfactory and impractical. a

An object of the present invention is to provide a jack for use in the type; of. machine, above referred to,,on which shoes supported on ordinary commercial flastsmay .be' secured uniformly in pretermined position so as to bemanipulated and presentedproperly to the operating devices of the machine. I

With this and other objects in view, a feature ofthe invention contemplates the provision in a shoe supporting jack having a toe .rest, of novel and improved shoe securing means including a heel gage for determiningthe position of the bottom surface of the shoe-with respect to thetoe rest by direct contact with the bottom of the heel portion. Broadly considered, this feature of the invention contemplates the provision of any suitable means cooperating with the heel gage for curing the shoe on the jack. In the construction hereinafter described, means are provided for forcing the shoe upwardly against the heel gage, this means comprising a'last engaging member in the form of a heel post provided with a pin to enter the last pin hole of the last and arranged to engage the top surface of the last. In its preferred form, this feature of the invention also contemplates providing the heel gagewith a surface, for engaging the end of the shoe and mounting the heel gage so that it is movable toward and from the toe rest to locate the shoe regardless of size longitudinally of the jack. The mechanism for securing the shoe in place may be actuated either automatically or manually, but in the illustrated embodiment of the invention this 75. mechanism comprises a manually operable jacking lever mounted on a cam shaft which, when operated, first acts to lock the heel gage in position and then to force the heel post upwardly to ward the heel gage. a In previous machines of the type in which the shoe is fed or the positioning movements controlled at least in part bythe machine, manually adjustable toe gages were provided upon the toe rest of the jack in order to fit the forms of different styles or sizes of shoes. According to another feature of the present invention, means are provided for automatically adjusting the gages for centering the toe of the shoe laterally of the jack. The toe centering gages are,

, in the illustrated embodiment, connected together to movein opposite directions with relation to the center'line ofthe jack. A toe end gage may be employed in conjunction. with the centering gages to fix more definitely the position of the shoe lengthwise of the jack. Any suitable means may be provided for moving and holcl ing the toe centering gages in position and, in the embodiment hereinafter described, locking means is provided for retaining the centering gages in place subsequent to their adjusting movement, which means is actuated during the jacking operation.

Other features of the invention consist in cer tain novel constructions, combinations and arrangements of parts, hereinafter described and claimed, the advantages of which will be obvious to those skilled in the art from the following description and drawings in which, Fig. 11s a view in front elevation of a machine embodying lines the relation of a shoe, supported by the jack; Fig. 7 is a view vertical section taken along the line '?'7 of Fig. 6; Fig. 8 is a view in elevation of the toe supporting parts in Fig. 6 from the left hand side; and 9 is a similar view of the parts shown in Fig. 8, illustrating,

their normal position when no shoe is supported on the jack.

The invention, as illustrated in the drawings,

is shown as applied to an automatic welt or turn shoe sewing machine of the same construction and mode of operation, except as hereinafter pointed out, as that described. in the United States Patent No. 1,616,714, grantedjointly to L. E. Topham and the present applicant, dated February 8, 1927.

The -machine comprises sewing mechanism mounted in a frame 2 supported upon the base 4 of the machine, a shoe supporting jack comprising a toe supporting arm 6 rigid with a spindle 8, a jack supporting structure comprising arm 10 in the forward end of which the lower end of the jack spindle 8 is rotatably mounted by means of a gimbal joint, a support 12 upon which the arm 10 is mounted to swing vertically, a frame 14 pivotally mounted at its lower end in the machine base so as to be capable of swinging about a horizontal axis and upon which the support 12 is mounted so as to swing about a substantially vertical axis, a vertical pattern cam shaft 16 mounted in the machine base carrying a series of cams 18 and a driving and stopping mechanism supported in a frame 20 mounted on the machine base at one side of the frame 2 of the sewing mechanism. The jack supporting structure is such that the jack can rotate about the axis of the spindle Sand can tip in any direction about the gimbal'joint at the lower end of the spindle. During the operation 'of sewing the illseam of a shoe mounted on the jack, the lower end of the jack spindle is moved forwardly and rearwardly and laterally of the machine and the jack spindle is rotated, so as'to maintain the shoe at all times in the proper relation to the sewing devices. These movements are imparted through suitable connections actuated from the cams 18 on the pattern cam shaft 16.- The shoe is fed by the feeding devices of the sewing ineci anisrn and also by a feed lever 22 which is actus ated from a cam on the pattern camshaft 16 and which controls the longitudinal position of 'the shoe in the machine. At the conclusion of the sewing operation, the thread is cut and held, the sewing mechanism is stopped with the needle free of the work, the welt is severed and the jack is moved outwardly away from the sewing devices and rotatd reversely to its originalposition.

In the machine of the patent, the lasted shoe was supported upon the jack by means of a toe i rest on the rigid toe supporting arm and by means of a heel post provided with a last pin engaging the pin hole of the last. The height of the rear portion of the bottom of the last frorn the gimbal joint at the lower end of the jack spindle and the transverse plane of the bottom of the last were determined solely by the engagement of the last pin with the pin hole of the last and, consequently, in order that a shoe, regardless of its size or style might be located on the jack with its bottom surface in predetermined uniform position, special lasts were used inthe machine, uniform and predetermined as to certain of their dimensions and particularly to the location of the last pin hole and the height of the last.

The jack illustrated in the drawings, as embodying the several features of the present invention, is designed to support an ordinary commercial last in predetermined position on the jack and-withlits bottom surface at a predeternnned heightfrom the pivotal support at the lower end of the jack and in a predetermined plane. To

end, an important feature of the jack consists of a heel gage which, as shown, comprises a pair of fingers 24 extending laterally and downwardly from the upper end of a gage carryingarm 26 pivoted at its lower end at 28 upon a rigid portionof the jack frame. These fingers areconstructed and arranged to engage .the bottom surface 30 of the heel portionof a lasted shoe 32 supported in the jack and are so located withrelatioh to atoerest 34 on the toe supportingarm 6 that thebottom surface of the shoe will be in the desired plane longitudinally of the shoe and at the desired distance from the pivot atthe lower end of the jack spindle. The fingers are ar ranged to contact with the bottomsurface of the shoe at the edges or at each side of the longitudinal center line of the shoe bottom 30 and thus act to position the shoe bottom in the proper transverse plane when the shoe is heldagainst the fingers. The gage'carrying arm 26 is movable towards andfrom-the toezrest and, in orderto cooperate with the toe rest in locatingthe'shoe longitudinally-in'the jack, is provided with a vertical surface shoe. v

The means illustrated in the drawingsfor forc' ing'the shoe upwardly against the heel gage comprises a heel post 38 provided at its upper end with a short projection 40 adapted to enter the pinhole 42 of the last. The heel post 38-is mounted in'the jack so as to be vertically movable to force the shoe upwardly against the heel gage by engagement with the top of the last and is also so mounted that its upper end can move longitudinally of the shoe to enter the pin hole of any size of last. As illustrated, the heel post is pivotally mounted at 440m one end of a lever 46,- whichlever is fulcrumed for'convenience on a the pivotal support 28for the gage carrying arm 26. The heel post 38 can thus move longitudinal- 36 to engage the heel end of the 1y of the shoe about its pivotal connection with the lever and can be forcedupwardl'y by a counter-clockwise movement of the lever 46. The piv- 0t 44 between the heel post 38 and the lever 46 being mounted at the toe rest side of the heel gage pivot 28 is'so located with relation to the heelgage fingers'that any upward movement of the heel post will applya force to the shoe along a line passing to the rear of the points of contact of the heel gage fingers, thereby tending to tip the shoe about the fingers as a"fulcrum and force the toe portion of the shoe downwardly against the toe rest. The'projection' 49 at the upper end 'of the heel post 38 is of a size to enter the pin'hole'of any commercial last and, in view of the fact that the pin hole of a'commercial last is located substantially at theicenter of the top surface of the last, the heel postacts'as a means for centering the heel portion of the last laterally with respect to the jack.

When there is no shoe in the jack, the heel post 38 and the gage carrying arm 26 assume the position indicated in Fig. 2, both being in a position nearer the toe rest than when the smallest size shoe to be operated upon is in the jack.

The gage carrying arm 26 is yieldingly held in position by a spring 48 attached at one end to the rigid toe supporting arm 6 of the jack, and at the other end to a pin 59 in a projection 52 from the lower portion of the gage carrying arm. The movement of the gage carrying arm under the force of the spring 48 is limited by the engagement of a stop projection 54 formed on the forward end of the arm 52 with the rigid toe supporting arm 6 of the jack frame. The heel post 38 is yieldingly held in the position indicated in Fig. 2 by means or" a spring 56 stretched between a pin on the lever 46 and a lug 58 on the lower end of the heel post below its pivotal connection with the lever. The movement of the heel post under the force of this spring is limited by the engagement of the post With the pin 50. With the parts in the position illustrated in Fig. 2, with no shoe in the jack, the heel post 38 is also held yieldingly in raised position by means of a spring 68 stretched between the inner end of the lever l6 and the pin 50, the movement or" the lever under the force of the spring being limited by the engagement of stop surfaces 62, 64, formed on the lever and on the forwardly projecting portion 52 of the gage carrying arm 26, respectively.

In the illustrated construction displacement of the shoe on the jack is prevented by locking the gage carrying arm in position and then applying plate 68.

an additional force to the heel post. At the outer end of the projection 52 of the heel gage carrying arm 26 there is provided a sliding and swinging pawl 66 arranged to engage one of a series of rack teeth formed on a rack plate 68 mounted in the toe supporting arm 6 near the toe rest. The forward end of the pawl is formed with a slot through which a pin '74 mounted in lugs at the end of the projection from the gage arm passes. The rear end of the pawl 66 is pivotally connected to one arm of a bell crank 72 fulcrumed at 74 on the projection 52 from the heel gage. The other arm of the bell crank 72 is connected by a link 16 to one arm of a second bell crank 78 pivotally mounted the heel gage arm on a shaft 80. The other end of the bell crank 78 carries a roll 82 which engages a cam 8 on a shaft 86 passing loosely through the heel gage arm and carrying at one end a jacking lever 88 pinned to the shaft. The roll 82 on the bell crank 78 is maintained in engagement with the cam 84 by a spring 90 attached at one end to 2. lug on the bell crank, and at the other end to the pin 50 in the projection 52 from the heel gage. This spring also acts in'a direction to move the bell crank 72 in a direction to break toggle formed by one arm of the bell. crank and the pawl 66, so as to move the pawl 66 out of engagement with the teeth of the rack After the shoe is in position with its heel against the heel gage, a movement of the lever 83 in a clockwise direction moves the pawl 66 into engagement with the teeth on rack 63, and locks the heel gage against movement. The heel post 38 is then forced upwardly to ciamp the heel seat of the shoe against the fingers at on the heel gage by a cam 92 mounted on shaft 86 to which secured the jacking lever 88. This cam 92 is arranged to bear on the outwardly extending arm of the lever 46, the arrangement being such that when the jacking lever is moved in a clockwise direction, as above described, the lever 46 is swung on its pivot by the cam 92 in a direction to move the heel post 38 upwardly. The pressure of the heel post 38 against the top of the last also serves to force the toe of the shoe into firmer engagement with t is toe rest, tending to tip the shoe downwardly about the fingers on the heel gage arm 26.

According to another feature of the invention, the toe supporting arm 6 of the jack is provided with a number of toe gages 94, 96, and 98 (see Figs. 6 to 9) for contacting with the bulging upper of the lasted shoe on the jack, while leaving the space just above and below the plane of the sole free for operation of the stitch forming devices. The gage 96 is a part of a bracket 100 which is screwed or otherwise firmly attached at the upper end of the toe supporting arm, and serves to limit the movement of the end of the shoe in a length-- wise direction. The gages Q4 and 98 are piv-- otally mounted upon shouldered screws 102 threaded into lugs extending from each side of the toe rest bracket. The screws 102 are divergently disposed with relation to the center line of the jack, so that the

gages

94 and 98 are movable laterally through paths inclined toward the heel gage arm, as well as in a direction toward and away from each other. The two

gages

94 and 98 are caused to move by equal amounts in order to coordinate their position with relation to the center line of the jack by

interengaging gear segments

104 and 106 extending from the pivot portions of

thegages

94 and 98 respectively. The gage 94 is moved inwardly by a spring 1 38 stretched between the segment 104 and a pin 110 (see Figs. 2 and 3) fixed in the toe supporting arm of the jack. The force of the spring 108 is transmitted to the segment 106 to move the other gage 98 inwardly. As the shoe is moved toward the toe rest, the toe of the shoe first strikes the movable toe gages 94 and 98, causing them to be spread apart by equal amounts until the shoe is brought to rest against the end gage 96. These gages thus act under the influence of the spring 108 and the

gear segments

104 and 106 to center the toe of the shoe on the jack, and are effective regardless of size or style of shoe.

The centering gages are locked in adjusted position by a latch 112 pivoted at 114. in a slot formed in the bracket 100. gear segment 16-6 is pro vided'with a series of teeth 116 cooperating with the latch to lock the centering gages against movement when the latch is moved into engage-- ment therewith. This takes place during the time when the shoe is being jacked, and in the present construction, is produced by the movement of a platen 118 extending from the pivot 114 and attached to the latch in a suitable position to be operated by the toe of a shoe in forcing it downwardly against the toe rest. The latch is normally separated from the teeth on the segment 116 by a spring 120 compressed between the platen 118 and the toe rest. platen may be regulated by an adjust ng screw 122 threaded into the bracket 19D, beneath the outer end of the platen. For convenience in corn struction, a socket 12% (see Figs. 1, 2, and 3) .ior y,

connecting the end or" the jack feeding lever 22 is also attached to the bracket 100 on which the toe gages are mounted.
