SOLE-FORMING MACHINE.

Original application filed July 9, 1919, Serial. No. 309,555. Divided and this application fi1ed November This invention relates to machines for use inthe manufacture of shoes,.the presentapplication being a division of our co-pending application Serial No. 309,555, filed July 9, 1919.

An object ofthe invention is to provide a novel form of leveling device, which, with out sacrifice of other utility, will be especially adapted for use in a relasting ma chine. From this point of view the invention comprises a beating or equivalent. leveling device which is normally held in an idle position, to be out of the way during the relasting operation, and which can be moved against the sole of a bottomed shoe to operate thereon, as for example after the shoe has been relasted.

It is preferable that a device of this character should be driven only when in use, and accordingly iour invention contemplates the use of. power-driven connections controlled by relative movement of a shoe and the device, as by throwing a clutch, so that the device operates only when in en.- gagement with a shoe. In the illustrator embodiment of the invention a beater is Fig. 1. is aside elevation of a relasting and leveling machine with parts of the machine in section and showing the last support in the position it occupies while the forward part of the shoe is being pulled thereon;

F ig. 2 is a side elevation of the beater mechanism and the last support showing the latter in the position it occupies while the heel portion of the shoe is being pulled thereon;

Fig. 3 is a somewhat diagrammatic cross section on the line 3-3 of Fig. 1 showing certain clutch controlling mechanism; and

Serial No. 603,821.

Fig. 4: is a section on line 44: in Fig. 2.

In the drawings denotes the vmain frame having a forwardly and upwardly extending portion 12. To the base of the main frame there is pivoted for universal motion at 1 1, a post 16 to the top of which is hinged at 18 a last support 20 having a slidable pin 22 mounted therein to receive the last 24:. "The post 16 has anabutment surface 19, the purpose of which is to engage a similar surface 21 on the last support 20 and to serve as a stop for the latter when the last support 20 is swung about the pivot 18 to shoe-inverted position. In this position, the last support 20 forms, in effect, an extension of the post 16. Near the upper end of the post 16 is mounted a fork 26 to receive and support the heel end face of the last when positioned as indicated in Fig. 1. To hold the post 16 in fixed position while the forward portion of the shoe is being pulled on to the last there is provided a latch 28 provided with a pin having a tapered upper end 30 adapted to seat itself, in a correspondingly shaped socket in arm 32 of the main frame. A spring 84 tends to thrust pin 30 int-o its socket from which it may be withdrawn by suitable mechanism,

which, as exemplified in the drawings, consists of a pin 38 mounted in the lower end of the latch member and adapted to withdraw the same upon the operation of treadle 86. Pivoted to this treadle is a hook member 42 adapted to engage a pin 44? mounted operator to release the hook whereupon the treadle may be raised and the latch member 3O seated. I

Turning now to the means for seating the last in the forward portion of the shoe,.there.

is provided a support 50 for the solo at the toe of the shoe carrying two blocks 52 ofrubber or other suitable material to engage and grip the sides of the toe portion ofthe shoe. This support 50 is pivoted at 5 1 to a rod 56 yieldingly held by spring 58 in a sleeve 60 at the lower end of which is formed a yoke 62 pivotally mounted on the main drive shaft 100. A roll 64: is provided at the lower end of rod 56 and is held by spring d 58 against a cam 66 so that upon rotation of the cam by means presently to be described the support 50 will be rapidly vibrated.

Pivoted to the sleeve 60 is an extensible link 67 provided with a compression spring 68 to yieldingly connect the toe support 50 with a gripper 70 pivoted to the main frame at 72 and provided with jaws 74 and 76 adapted to grip the heel portion of the sole of the shoe. Pivoted to the base of the main frame of the machine at 7 8 is a treadle 80 made in the form of a bell-crank lever and pivoted at its upper portion 82 to a link 86, the latter being pivoted at 88 to one end of a U-shaped lever 90 pivoted at 92 to the main frame. The U-shaped lever 90 is pivoted at 93 to one end of a link 94 the other end of which is pivoted to the downwardly extending end of the pivoted jaw 76 of the gripper. The treadle 80 is normally held in its raised or inoperative position by means of a spring 96 connecting it with the main frame.

While the machine is at rest the support for the forepart of the shoe and the grippers occupy substantially the position indicated in dotted lines in Fig. 1. A last having been placed on the pin 22, and occupying the position indicated in Fig. 1, the shoe is placed with the forepart of its sole on the toe support'and the rear portion of the sole between the jaws of the gripper. The depression of treadle 80 operates first to close the jaws of the gripper upon the sole of the shoe and then to swing the gripper downwardly and to the right, as viewed in Fig. 1. This downward swinging movement is transmitted by link 67 to the toe support, the two co-operating to pull the shoe on to the last. The movement of the yoke 62 of the toe support about shaft 100 operates as will now be described, to throw in clutch mechanism which causes cam 66 to vibrate the forward portion of the shoe to settle the same on the last.

Mounted on the main drive shaft 100 is a belt pulley 102 about which passes a belt 104 driven from any suitable source of powe1. Connected to shaft 100 is a pulley having grooves to receive belt 106 and 108 which drive other operating parts of the machine presently to be described. On the depending portion of one of the arms of the yoke 62 (see Fig. 3) is an inclined or wedge sur face 112 adapted upon the swining of sleeve 60 to co-operate with a corresponding wedge surface 114 formed on a sleeve 116 rigidly mounted on pin 118. This pin 118 is mounted for longitudinal movement in the main frame and is moved in the direction of wedge surface 112 by a compression spring 120. The yoke 121 formed on the sleeve 116 operates to control a clutch member 122 to move the same towards and away from a co-operating clutch member 124 formed integral with the cam 66. It will thus be seen that the movement of the toe support from dotted to solid line positions in Fig. 1 will operate to permit the sleeve 116 to be slid to the-left as viewed in Fig.3 under the action of the spring to throw the clutch 122, 124 into operation and consequently to vibrate the rod 56 and the toe support.

After the last has been inserted in the forepart of the shoe the last support is swung upwardly by the operator about pivot 18 to invert the same and the last is then rotated in a horizontal plane through 180 to position it as indicated in Fig. 2.

Pivoted to the base of the main frame of the machine is a third treadle to which is connected a rod 132. Supported at the upper end of this rod is a shoe horn co1nprising a pair of co-opera- ting jaws 134 and 136 for gripping and pulling the shoe downwardly on to the last. The gripping portion of jaw 134, as indicated, is of more or less conventional shoe horn shape and is adapted to be inserted insideof the shoe and to be pulled down between the upper and the last. J aw 136, which may be a block of rubber or other suitable material, is pivoted to the bell-crank lever 138 which latter is pivoted at 140 to the extremity of a handle portion 142 of the shoe horn. The other arm of the bell-crank lever 138 is pivoted to the extremity of the rod 132 which latter passes through an opening in an extension of the lower end of the shoe horn. Rigid with the post 16 is an outstanding arm 144 provided with an elongated slot to movably hold the rod 132 in position.

Journaled in the post 16 is a shaft on which is mounted clutch mechanism similar in all its essential characteristics to that of Fig. 3, and adapted to be thrown into and out of operation by the movement of an arm 152 through which passes rod 132, the arm 152 being moved into and out of clutch engaging posit-ions by means of collars 154 and 156 rigidly but adjustably mounted on the rod 132. A downwardly extending portion of the arm 152 carries a wedge surface, a movement of which towards and from operative position controls the operation of a cam 158 in the manner explained in connection with Fig. 3. Engaging the cam 158 is a roll 160 mounted on a downwardly extending yoke portion 162 of a rod 164, this latter being mounted for longitudinal vibrating movement-in the post 16. To hold the roll 160 in engagement with the cam 158 there is provided a spring connected at one end to an eye 171 formed on the yoke 162 and at its other end to the post 16 at 172. The upper end of the rod 164 contacts with the lower end of the pin 22, when in the position indicated in Fig. 2, to vibrate the last in a direction transverse to the plane of the sole thereof to assist in settling the shoe on the last as the heel portion of the upper is drawn into position by the shoe horn.

To assist in settling the shoe on the last and to shape the sole thereto there is provided a beater which may bethrown into and out of operation by means of a handle 180 pivoted upon a shaft: 197 which is journaled in the upper portion of the main frame and is driven by means of the belt 108. The handle 180 is adapted to be locked in operative position by means of a sliding pin 182, controlled by a pivoted lever 183, held in operative position by a spring 185, as clearly shown in Fig. 2. This beat-er comprises a rod 18 1 slidably mounted in a carrier or sleeve 186 and having a beating head 188 connectedby a ball andsocket' joint 190 to its lower end. A spring 192 connected to the rod 184 and the sleeve186 of the beater normally tends to hold the beater in its lowermost position relatively to the sleeve 18G. Clutch mechanism similar to that of Fig. 8 is provided for controlling the operation of the beater so that the same will be vibrated when moved into the position of Fig. 2, but will come to rest when the handle 180 is elevated by a suitable spring 207, as indicated in Fig. 1. For this purpose the handle 180 is provided with a wedge surface 194 cooperating with a wedge surface 196 of a clutch shifting yoke, the two controlling the operation of a clutch ,inounted on the shaft 197, in the manner described in connection with Fig. 3. Mounted on the shaft 197 and. controlled by this clutch is a cam 200 co-operating with a roll202 for reciproeating the beater. The roll 202 is mounted on a link 201 shown in dotted lines in Fi 1 and 2 and in cross-section in Fig. 1 pivoted at one end to the handle 180 at 181 and pivoted at the other end, as at 205, to thelower end of the link 206. The upper end of the link 206 is pivotally connected to the stem 184; of the beater. The sleeve 186 of the heater is pivoted at 208 to projection 210 of the handle 180 and is also pivoted at its up per end to a link 212 connecting it with the forward portion of the main frame of the machine. It. will thus be seen that the rotation of cam 200 will rock the lever 204 about its fulcrum 181 and will thus reciprocate the link 206 andthrough it the beater.

In order to tension the belt 106 to the desired extent irrespective of the positionof the post 16 a suitable belttightener, indicated at 214, is provided.

While it is believed that the mode of operation of the machine will be clear from the above description it may, for purposes of convenience, be recapitulated as follows.

A last having been placed on pin 22 and the same moved to the position of Fig. 1,

the forepart of the shoe is placed thereover so far as convenient by hand. At this time the toe support and the. grippers for the heel portion of the sole occupy substantially the positions shown in dotted lines in Fig. 1. The operator thereupon presses downwardly upon treadle 80 which first closes the jaws of the gripper upon the heel portion of the sole of the shoe and thereafter moves the gripper and the toe support 50 rearwardly and downwardly to the full line position of Fig. 1, thus seating the last in the forepart of the shoe. As the support 50 is thus moved, cam 66 is operated to vibrate the toe support and the shoe to settle the last in the shoe. Treadle is now released whereupon spring 96 moves the gripper 70 and the toe support 50 back to the dotted line position of Fig. 1, leaving the last inserted in the forepart of the shoe. Handle 180 and the beater being in their elevated or inoperative position, the last is now swung forwardly and rotated horizontally to the position of Fig. 2. The shoe horn is now manipulated manually by means of handle lAl-2-to grip the rear portion of the upper of the shoe which has now to be pulled down into place. By means of treadle 130 the operator pulls the rear portion of the upper held by the shoe horn down into place and at the same time the last is vibrated through rod 164, cam 158 and their actuating mechanism. During these opera tions post 16 is, of course, rigidly held in position by its latch mechanism. When the last is nearly or completely inserted in the shoe the operator pulls down on handle 180 latching the same in the position of Fig. 2, whereupon beater 188 is vibrated to settle the'shoe on the last. At this stage of the operation by pressing downward ontreadle 36 the operator releases the latch of the post 16 and thereafter moves the post from one position to another in order that the beater may shape and mold various portions of the sole of the shoe as may be necessary. Handle 1 12 of the shoe horn at this stage of the operation forms a convenient means by which the operator may swing the post from one position to another.

The above-described relasting mechanism is not claimed herein, as it forms the subject-matter of our parent application No. 309,555. Other features of novelty not claimed herein, relating to the means for supporting and for vibrating the last, are claimed in our divisional application, Serial No. 251,433, filed Febj2, 1928.
