JERSEY.

Application filed April 14, 1925,. Serial No.

This invention relates to shoe pressing machines and is illustrated as embodied in a socalled automatic leveling machine of the type disclosed in United States Letters Patent No. 1,239,66el, granted Sept. 11, 1917, on the application of WV. 0. Baxter, although the 1nvention in various aspects is not limited to embodiment in machines of this type.

In leveling machines of this type, the shoe is supported on a last which rests on a jack comprising a heel post and a toe post or support, and is held firmly thereon by appropriate mechanism. These supports as a whole are adjustable to fit the shoe hem-g treated and the jack is rocked back and forth under a leveling roll which exerts a heavy pressure on the shoe.

Y It has been found in leveling shoes on ointed lasts having relatively movable heel andfore parts, such as hinge lasts, that the bonding mechanism between the last parts is sometimes too weak to take the pressure of the leveling tool and that consequently the pressure sometimes distorts or breaks the last, thus causing damageto the shoe being treated.

It is a principal object of the present invention to prevent such damage, and to this end the invention provides an improved shoe pressing or leveling machine organization 1ncluding a support for the last in the neighborhood ofthe oint between the heel end and the forepart. Preferably this support will be in adition to the heel and for-apart (or toe) supporting mechanisms heretofore characteristic of leveling machines. In the embodiment shown, the supporting mechanism com prises a finger arranged to enter a cut or de pression between the last parts, to support the last.

In another aspect, the invention provides supportingmeans for a last between its ends constructed and arranged to be automatically positioned and locked in last-supporting po sition, which, although generally applicable to pressing or leveling machine organizations of *arious types, is very well adapted for use in an automatic roll leveling machine of the type above referred to. Preferably, and in accordance with a further feature of the invention, the support for the intermediate or joint portion of the last automatically measures the distance from its contact point with the last to a member or abutn'lent to NEW JERSEY, A CORPORATION OF NEW snon-rnnssrne MACHINE.

which the pressure imparted by the leveling element to the last is transmitted, thus avoiding the necessity of adjustment for different styles and sizes of lasts. Conveniently, and in the disclosed embodiment of the inven tion, the result above stated is accomplished by an organization in which the finger above referred to is resiliently forced upwardly to meet the last, and in which the lower end of the finger is supported through a cam which cooperates with it in varying relations, depending on the contour and dimensions of the last. Preferably, also, the cooperation of this cam with the finger is automatic and is controlled by the operations of jacking and unjacking the shoe (or last) so that the operator needs to devote no attention whatever to the supporting means. 7

Another feature of the invention consists in a novel construction whereby the last sup porting means is rendered adjustable to contact with the last in the desired locality, considered longitudinally of the last. in the illustrated machine which is adapted especially for the treatment of shoes on hinge lasts of the type having a V out in their upper surfaces to permit the hinging collapse, the desired result is attained by pivoting the contact member for longitudinal movement relatively to the last, so that it automatically slides into the V to seat itself in position to support the last in the region of its joint or hinge.

These and other features of the invention comprising certain novel combinations and arrangements of parts will be understood from the following description of a preferred embodiment thereof selected for purposes of illustration and shown in the accompanyin drawings, in which,

Fig. 1 is a side elevation of the front portion of amachine of the type referred to.

Fig. 2 is a perspective view of the jack mechanism as seen from the right side.

Fig. 3 is a somewhat enlarged view of the twin mechanism on the other side of the machine as seen from the left side.

The illustrated jack mechanism in various respects is identical with that shown in the Letters Patent referred to and reference may be had to said Letters Patent for a more complete disclosure of the construction and operation of parts not fully described herein. The jack as a whole is oscillated under a leveling roll about the axis of a rock-shaft 12, on which it is mounted, by power-operated mechanism which need not be described in detail since it is fully disclosed in the abovementioned Letters Patent. The roll is supported in a fork 11 which is hinged at its rear end and forced down toward the jack by heavy springs. The oscillation of the jack follows a cam-controlled cycle, and the jack is automatically thrown out to unjacking and jacking position at the end of the cycle, all of which will be clear by reference to the patent. The jack consists essentially of a toe post 14 mounted on the shaft 12, and a heel post 16 which is pivoted at 18 to a crank-arm 20 depending from the toe post. The relative adjustment of the two posts is effected by a hand-screw 22, extending between the heel post and a lug on the hub of the toe post. The jack pin 24 is tilted away from the operator by a rod 26 operated by gearing 28 and a wrench-receiving head at 30. The shoe is jacked by placing the jackpin hole of its last on the jack pin 24, adjusting the screw 22 until the toe of the shoe falls properly into the toe rest 32, and turning the head 30 until the tilting of the jack pin forces the toe of the shoe firmly into the toe rest. All of this mechanism is substantially as shown in the patent referred to.

Pivotally mounted on the heel post 16, and conveniently on the shaft 34 of one of the gears 28, is a cam or looking member 86, having a downwardly extending tail 38. A swinging lever is pivoted at 42 at the bottom of the heel post and has a lug 44, arranged to be engaged by the cam 36, which swings around its pivot to contact with the lug in any position which the latter may assume. When the jack is swung out and down toward the operator to jack or unjack a shoe as shown in Fig- 3, a fixed bracket 46 on the machine frame contacts with the tail 38 and prevents the cam 36 from following the lug 44, thus stressing a spring 48 which tends to throw the cam on to the lug. The lever 40 is then free to swing in either direction about its pivot 42. The lever 40 is U-shaped and embraces the lower end of the heel post.

On the other end of the lever 40 at 50 there pivoted to the lever the lower end of a rod 52, which slides lengthwise in a guide 54, and is resiliently held in raised position by a spring 56 attached to a lug on the rod at its lower end. Pivot-ed at 58 to the upper end of the rod 52 is a last contacting finger 60, having a spring-pressed pin 62 in it which engages a V cut in a lug 63 at the upper end oft-he rod 52 as shown in Fig. 3, to hold the finger resiliently in a mean or standard po sition.

The machine being in the condition shown in Fig. 3, the operator puts the shoe on the jack as described above, and the finger contacts with the last. The last shown has tomatic.

a V out at its hinge joint and the finger automatically enters it and settles to the bottom of it, rotating about the pivot 58 if necessary. In case the same type of last is to be used exclusively on the machine, the finger will conveniently be made to fit the last in any desirable manner. As shown, the finger,-by reason of its pivotal mounting at 58, is adapted to cooperate efficiently with any last with a V cut. As the last settles down on the jack pin, the finger 60 and the rod 52 are forced down against the spring 56 carrying the lever 40 with them, (the cam 36 being inoperative,

as already explained) until the shoe is in.

proper position on the pin. The operator will then swing the heel post'toward the toe post, if such adjustment is required by the length of the shoe, and will lock the shoe in the jack. When the machine is started and the jack starts to swing up under the roll 10, as shown in Fig. 2, the tail. 38 leaves the bracket 46 and the spring 48 pulls the cam 36 against the lug 44, thus locking firmly the lever 40, rod 52 and finger 60 against downward movement under the leveling pressure, and the joint of the last is thus supported firmly against the pressure of the leveling roll, 'so that damage to the'last and consequently to the shoe is prevented. The shaft 34 constitutes an abutment which takes the pressure transmitted from the last through the rod, lever and cam. It will be clear that this mechanism comprising 'provision for a variable operative relation between the cam 36 and the lug 44 constitutes in effect a measuring means for the distance between the last and the abutment, or a take-up mechanism between. these parts.

It will be clear that the operation of the illustrated supporting device is entirely au- It unlocks when the jack swings out to interchange shoes and locks as it swings back to operative position and requires no attention whatever from the operator.
