SOLE PRESSING MACHINE Filed Nov. 10, 1932 2 Sheets-Sheet 2 Patented Mar. 31, 1936 UNETED STATES PATENT OFFICE SOLE PRESSING MACHINE Application November 10, 1932, Serial No. 642,067

22 Claims.

This invention relates to sole pressing machines and more particularly to means for supporting boots or shoes for the sole pressing operation, and is illustrated herein as embodied in a machine of 1. the type disclosed in Letters Patent of the United States No. 1,549,243 granted August 11, 1925 on an application of E. E. Winkley. Machines of that type comprise a sole pressing member or pad arranged to apply pressure to the bottom of a boot or shoe on a last and a jack for supporting the boot or shoe against the pressure of the pad.

It is an object of the present invention to provide in a sole pressing machine an improved jack on which a long legged boot may be readily mounted without the necessity of distorting the long leg of the boot to avoid interference with the sole pressing pad. With this object in view a feature of the invention, in one aspect, consists in a novel organization comprising, in combination with a sole pressing pad, a jack having members for supporting a boot or shoe at the heel end and forwardly of the heel end against the pressure of the pad, the heel end member being displaceable in a novel manner relatively to the other member and the pad to facilitate the mounting of a boot thereon.

In the illustrated construction the jack is provided with a pair of arms arranged respectively to support the heel end and the forepart of the boot or shoe against the pressure of the pad, and in order that a long legged boot may be readily mounted on the jack the heel-end supportingarm is mounted to swing obliquely forward toward the operator and away from the forepart supporting arm into position to permit the operator to mount the boot thereon without distorting the leg of the boot and then to swing reversely to carry the boot into operative relation to the forepart supporting arm and the pad without interference between the boot and the pad. As shown there is provided friction means for holding the heel end supporting arm in work receiving position and also means for limiting its swinging movement into position to supper-t the boot against the pressure of the pad.

In order that the jack may be adapted to support both long-legged boots and also shoes of widely varying sizesmounted on lasts of different heights, there is provided in accordance with a further feature of the invention, novel means constructed to permit the heel end support to be adjusted heightwiseof the boot or shoe to'accommodate the jack to lasts of different heights. In the construction shown, the heel end support- 1 ingarm is formedintwo parts which are relatively adjustable heightwise of the boot or shoe to vary the length of the arm in accordance with differences in the heights of different lasts, means being provided for locking the two parts .of the arm against relative displacement from adjusted relation in response to pressure of the pad on the sole. In view of the fact that the jack is thus adapted to support both boots and shoes, the term shoe is frequently used hereinafter for convenience as applicable to both kinds of footwear. I

The above and other features of the invention together with various novel details of construction and combinations of parts will now be more particularly described by reference to the accompanying drawings and will be pointed out in the claims.

In the drawings,

Fig. l is a view in front elevation of as much of a machine of the type illustrated in the abovementioned Letters Patent as is necessary to refer to for an understanding of this invention with novel features of the invention embodied therein; and

Fig. 2 is a plan view of parts shown in Fig. 1.

The present invention is illustrated as embodied in a sole-pressing machine of the type shown in the above-mentioned Letters Patent to which reference may be had for a more detailed description of the construction, arrangement and operation of parts not fully described herein. The machine is provided with a pair of upwardly extending rods I on which there is adjustably secured a casting [2 for supporting a pair of downwardly extending arms or posts M, I6, of a shoesupporting jack. The arm M which, as shown, is of sufficient length to receive a long-legged boot is provided at its lower end with a pin ill for engaging the heel end of the last in its spindle hole, and the arm I6 is provided with a forked lower end 28 in which there is secured a shaft '22, upon which shaft there is loosely journaled a roll '24 for engaging the forepart of a shoe. Mounted for sliding movement on the rods I0 is a carrier 26 provided with means at its oppositesides for supporting a pair of trunnions, such as that indicated at 28, fast to a pad box 38 on which there is mounted a. resilient sole-pressing form or pad 32 the upper-surface of which is shaped to conform substantially to the longtiudinal and transverse curvatures of the bottom of a shoe on the jack. In the illustrated machine the carrier 26 is moved toward and from the shoe-supporting jack by suitable power-driven mechanism which is not shown or described herein but is fully illustrated and described in the above-mentioned Letters Patent. It will be understood that the shoe is mounted on the jack by the operator when the carrier 26 and the pad 32 are in their lowermost positions and that in the operation of the machine the pad is moved upwardly to apply pressure to the shoe before the machine comes to rest.

The heel pin I8 is supported on a holder 34 which is pivotally mounted at 36 on the arm I4, and the holder 34 is controlled by a spring 38 which tends to tip the pin I8 toward the roll 24. When the last is mounted on the pin I 8 the spring 38 accordingly tends to hold the forepart of the shoe pressed against the roll 24, thus assisting in maintaining the shoe in the proper position for pressure to be applied to the shoe bottom by the upwardly moving pad 32.

In order that a long-legged boot may be readily mounted on the jack without bending or folding over the long leg of the boot, the arm I4 is pivoted at its upper end so that it may be swung outwardly into a convenient position to receive the boot. As shown, the upper end of the arm is forked to straddle a boss 40 which is formed on a carrier block 42 slidably mounted on a plate 44 which is secured to the support I2. Extending through the boss 40 and the arms 46, 48 of the forked upper end of the arm I4, is a shaft 56 which is held against rotation in the boss 40 by a pin 52. Machines of the type illustrated in the Letters Patent referred to above are usually provided with duplicate sole-pressing mechanisms whereby one shoe is subjected to pressure simultaneously with the release from pressure of another shoe previously operated upon. In order that the arm I4 may be swung outwardly into a convenient position to permit a boot to be mounted thereon and then inwardly to bring the forepart of the boot beneath the forepart supporting roll 24 without interfering with the jack of the other twin mechanism or the uprights I0, the shaft 50 is so disposed that its axis extends in a direction inclined to the long axis of the boot or shoe.

Thus the arm I4 as it moves outwardly has components of movement longitudinally and laterally of the sole-pressing pad so that it swings from a substantially vertical position obliquely forward toward the operator and away from the forepartsupporting arm I6 into an inclined position to receive a long-legged boot without interfering with the jack of the other twin mechanism or the uprights I0. Moreover, it will be seen that since the arm I4 is pivoted at its upper end for swinging movement in a vertical plane, it may be swung into and out of operative relation to the arm I6 and the pad 32 without interference between the boot and the pad.

For holding the arm I4 in work-receiving position, while a boot is being mounted thereon by the operator, there is provided friction means comprising a pair of friction disks 54, 56, the disk 54 being secured to the flanged end 58 of the arm 46 and the disk 56 to a sleeve 60 mounted on the shaft 50 (Fig. 2). The sleeve 60 is counterbored to receive a spring 62 which tends to hold the friction disks 54-, 56 in engagement with each other and the tension of which may be regulated by a nut 64 which is threaded on the rod 50. For holding the sleeve 60 and the friction disk 56 against rotation, as the arm I4 is swung into and out of operative relation to the arm I6 and the pad 32, there is provided a pin 66 which is mounted in the sleeve 60 and extends through an aperture formed in the nut 64. A locknut 68 is provided for holding the nut 64 in adjusted position. The carrier block 42 is provided with an abutment shoulder I arranged to engage a similar shoulder 12 formed on the arm I4 and to serve as a stop for the latter when it is swung inwardly to bring the forepart of the shoe beneath the forepartsupporting roll 24.

The arms I4, I6 of the shoe-supporting jack are movable rectilinearly toward or from each other along the plate 44. In order to adjust them toward or from each other to accommodate the jack to shoes of different lengths, there is provided a lever I4 which is fulcrumed at I6 to the support I2 and is provided with a downwardly extending arm I8 connected by a link 80 to the arm I6 and an upwardly extending arm 82 connected by a link 84 to the carrier block 42. The lever I4 is provided with a handle 86 which extends outwardly into a convenient position to be grasped by the hand of the operator and by means of which the operator may swing the lever "I4 about its fulcrum 16 to move the arms I4, I6

toward or from each other.

In the illustrated machine the arm I4 comprises two parts relatively adjustable heightwise of the shoe to accommodate the jack to lasts of different heights. As shown particularly in Fig. 1 the arm includes a lower portion 88 and an upper portion 90 which is bifurcated to receive the lower portion 88 and is provided with a pin 92 which extends through a lengthwise slot 94 formed in the lower portion. The two parts of the arm are thus relatively adjustable heightwise of the shoe to vary the length of the arm to compensate for differences in the heights of different lasts. In order that the lower part 88 of the arm may be held in any one of a plurality of adjusted positions, it is provided with a series of grooves 96 which are spaced apart heightwise of the arm I4 and any one of which may receive a pin 98 carried by the upper portion 90. By this pin and groove construction the two parts of the arm are accordingly locked together against relative upward or downward movement. To prevent them from becoming unlocked the upper portion 98 is provided with a lengthwise slot I 00 in which there is slidably mounted a pin I02 carrying a roll I04. The roll I04 is arranged to engage an inclined surface I06 formed on the upper end of the lower portion 88 of the arm. It will be readily seen that after moving the roll I04 upwardly out of engagement with the inclined surface I06 the lower portion 88 may be swung about the pin 92 and raised or lowered as desired, and may then be swung into interlocking relation with the pin 98, after which the roll I04 may be moved downwardly into engagement with the inclined surface I06 to hold the upper and lower portions of the arm against displacement from adjusted relation.
