T 0 all u; from it may concern Be it known that 1, JOH R onsnnson, a citizen of the United States, residing at Melrose Highlands, in the county of Mid; dlesex and State of h/Iassachusetts, have in vented certain Improvements in Last-Pulls ing Machines, of which tl e follow ng description, in connection with the accompanying drawings, a specification, like reference characters on the drawings indicating like parts in the several figures. I

This invention relates to improvements in machines for separating shoes and their lasts. The invention is shown as embodied in a last pulling machine of the general type described and illustrated in United States Letters Patent No. 1,203,57l, granted Nov. 7, 1916, upon the application of John M. Benjamin. i

As previously constructed, last pulling 1m.- chines of this type have included a spring auxiliary 2 and cooperating with the last pulling mechanism and arranged to be tensioned during the early stages of: last and shoe separation responsively to the resistance offered by the counter portion of the shoe to the lengthwise thrust given the last'by said last pulling mechanism partially to reduce said thrust to prevent excessive strain against the back seam and subsequently to impel the last lengthwise of the shoe when the bottom of the last heel clears the top of the shoe counter. I

This auxiliary spring, in machines as previously constructed, acts against a hell crank lever to which a last carrier it attached. The resistance offered by the heel end or the shoe to lengthwise heelward thrust of the last as the last heel is moved out of the heel end of the shoe, reacts against said last carrier, causing said carrier to turn said bell crank lever against the action of the spring which yields and permitssaid turning movement, thereby reducing and relieving the lengthwise thrust given the last heel against the shoe counter by the action of the last pulling mechanism. This arrangement has proven very satisfactory in factory use generally. In a few instances,

however, the strain upon the forepart of the,

shoe upper at the throat of the vamp or the ball portion of the upper has caused the upper materials to be broken out.-

An important feature of the present invention consists in novel means auxiliary to and cooperating with the last and shoe separating mechanism to augment the lengthwise relative thrust'given by said mechanism to the last heel and shoe counter at Ya point during the relative vertical movement of the last heel and shoe counter to clear each other to reduce the strain against the forepart of the shoe upper or throat of the vamp. The augmented lengthwise thrust is preferably only substantially momentary and by the present invention may be timed to occur when the greatest strain would otherwise be placed on the upper at the ball or vamp throat. Preferably, the means for augmenting the lengthwise thrust is adjustable to cause said thrust to occur at variably predetermined times in the cycle for varying conditions and constructions of shoes. Manifestly, shoes will differ in shape and construction and under these conditions means for varying the timewhen the lengthwise thrust is augmented is a substantial desideratum.

An additional feature of the invention consistsin novel means auxiliary to and cooperating with the last and shoe separating mechanism and efiective during the initial stage of last and shoe separation, to reduce relative lengthwise thrust of the last heel and shoe counter and subsequentlv effective at a determinate point to augment said rela tive lengthwise thrust to relieve strain.

against the torepart of the shoe upper. As shown herein, an abutment is fixed to the machine frame and is engag'ed'loy a relatively movable abutment member connected with and moved by the last pulling mechanism and engaging the fixed abutment at subsequent anddeterminate point in the last pulling operation positively to arrest or'stop said thrust reduction and to augment the thrust of the last lengthwise heelward against the counter portion of the shoe. This augmentation of thrust is substantially momentary only, the continued movement of the last pulling mechanism sliding the movable abutment member from cooperative engagement with the fixed member. The reduced lengthwise thrust enables the last to be started out of the shoe and by the time the last has been moved sulficiently to cause substantial strain against the throat of the vamp, the lengthwise thrust is augmented by the cooperationof said abutments to relieve such strain.

The illustrated machine embodies mechanism in the form of a plunger, a pivotally attached bell crank lever, and a last carrier pivotally attached to the upper arm of the bell crank lever for effecting movement of the last holding means to move the last from the shoe in a generally diagonally rearward direction relatively to the shoe, with auxiliary means in the form of an abutment plate depending from the lower arm of the bell crank lever and moving with said lever and plunger to engage a fixed abutment on the machine frame, said engagement moving the bell crank lever in a direction to cause said mechanism to augment the lengthwise thrust of the last heel against the shoe counter at a predetermined point in the movement of the last carrier to effectremoval of the heel of the last from within the counter portion of the shoe;

In another aspect, the invention presents as a further feature auxiliary means as shown, said movable abutment member cooperating with the mechanism and arranged for adjustment to increase the relative lengthwise component of the separating movement of the last and shoe effected through the last pulling mechanism at variably predetermined points in the last and shoe separating movement of said mechanism. This auxiliary means may cooperate with the last pulling mechanism independ' ently of a spring means such as previously described and may be adjusted to increase the lengthwise component of last movement before the last heel clears the top of the shoe counter so as to relieve strain on the vamp or subsequently to'this point in the operation, as for example, when the last heel has i cleared the top edge of theshoe counter so as to provide an accelerated lengthwise last movement which, in the case of high shoes, will overcome any resistance offered bythe back stay portion of the top of a high shoe.

These several features of the invention will be more fully understood from the following description, in connection with the accompanying drawings which show an illustrative embodiment of the invention, and will then be particularly pointed out in the claims.

Figure 1 of the drawings is a view in side elevation of a last pulling machine of the described type embodying the present invention and Figs. 2 to 5, lnclusive, are diagrammatic views illustrating the action of the improved last pulling mechanism in successive stages of last and shoe separation.

The illustrative machine embodies the essential characteristics of the last pulling machine of the Benjamin patent previously referred to,-and therefore, as to general construction and operation need only. be described briefly.

A heavy upright column 2, designed to rest upon a floor or other support, is formed with bearings for a power shaft 4 driven through a clutch member 8 when engaged with a continuously rotating pulley 6 loose on said shaft. The clutch is thrown in by depressing a treadle 10 which, through suitable ccnnections causes a connected cam shaft 12 to be turned through half revolution (representing one cycle of the machine) and automatically stops the shaft at the end of said half revolution. The cycle of operation may, obviously, be repeated by again depressing the treadle 10.

Rotation of shaft 4, through worm gearing 14'16 turns the cam disk 18 on cam shaft 12 through a half revolution, during the first part of which a positioned shoe is clamped between opposed count-ergrippers; the last within the shoe being subsequently removed from the shoe by certain mechanism operated from the power shaft. The counter gripping means may or may not be, but as illustrated are, similar to the counter" grippers and their associated controlling mechanism described and claimed in an application filed by M. F. Brogan, Serial No. 192,954. These or other suitable counter grippers are indicated generically by dotted lines in the diagrammatic showing in Figs. 25 inclusive.

In machines of the described type and in the illustrative machine, the initial movement of the cam 18 operates through a bell crank lever 20 and a plunger 22 to close the counter grippers against the opposite sides of the counter portions of the shoe which is positioned between the grippers by the operator priorto the starting of the machine. Subsequently, the cam 18 is effective to cause certain mechanism to pull the last from the gripped shoe.

The last with its shoe is mounted upon a heel pin Qtupstanding from a carrier arm 26, the rear end of which is pivotally secured to the upper arm 28 of a bell crank lever pivoted to the upper end of a plunger 30.

After the operator has mounted the last and thrust bar 38, whose forked upper end embraces the hub of a double-armed cam on the cam disk 18, as in the Benjamin patent previquently to the closing of the counter grippers and is effective to move downwardly the plunger 30 to pull the last from the gripped shoe. The pivotal points of connection of the carrier arm 26 to the bell crank lever 28 and of the bell crank lever 28 to the plunger 30 are in vertical planes located reawardly of the heel end of the gripped shoe. As the plunger descends, there i is, therefore, a lengthwise heelward thrust exerted by'the heel of the last against the counter portion of the shoe.

This thrust, unless otherwise controlled,-

may be sufficient to impose excessive strain upon the back seam at the rear extremity of the counter portion of the shoe so as to injure the shoe in extracting the last. By this invention, however, this lengthwise thrust is so controlled by auxiliary mechanism cooperating with the main last pulling mechanism as to prevent injury to the shoe. Accordingly, the lower arm 40 of the bell crank lever has pivoted theretothe upper end ofa rod 42, the lower end of which is reduced in diameter and has a free sliding fit with lateral play in a tubular guide 44: carried at the forward end of a bracket 46 which, in turn is fixed to the plunger 30. adjacent to its lower end. A coiled spring 48 is sleeved upon the rod 42 between the tubular guide as and an adjustable abutment or throw back plate 50 threaded upon the enlarged and threaded upper end of the rod 42, a check nut being preferably employed to lock the plate in adjusted position.

The abutment or throw back plate 50 is designed to engage its edge surface for a short time, or substantially momentarily with the edge portion of a shelf or abutment plate 52 outstanding "from a bracket 54 serv- I ing also as a guide for the plunger 30 and rigidly secured between suitable projections from the face of the column 2. Since the bell crank lever, rod 42, guide as and bracket as are moving downwardly with the plunger 30, the engagement of the throw back plate 50 with the abutment plate 52 will cause the upper arm 28 of the bell crank lever to be swung rearwardly as the plunger contlnues to descend, exerting augmented lengthwise heelward thrust of the last heel against the shoe counter. The adjusted position of the plate '50 predetermines the point in the last pulling operation when this augmented lengthwise heelward thrust becomes effective. The coiled spring 48 sleeved upon the rod l2 is intended to reduce the lengthwise heelward thrust of the last heel against the shoe counter during the initial portion of the movement of the last heel out of the counter portion ofthe shoe, so as to enable the last to be easily started out of the shoe and to follow the contour of the counter at the rear extremity ofthe shoe without exerting exces'sive strain against the counter and back seam; Subsequently, the throw back plate 50 engages the shelf 52 and is effective to pre vent further thrust-relieving yield of thebell crank lever and as the plunger continues to descend, acts to swing the bell crank lever reversely to augment the lengthwise thrust of the last heel against the shoe counter at the point in the last pullin operation predetermined by the initial adjustment of said throw back plate.

The action of these parts in relation to the cycle of shoe and last separation will be more clearly apparent from the diagram matic showing of Figs. 25 inclusive of the drawings. In Fig. 2 the parts are shown in the position they occupy at the start of the last pulling operation, the shoe being held between the opposed counter grippers and the heel pin 24 having been tilted to cramp andbind in the last by the initial downward movement of the plunger 80. In the movement of the parts from the position shown in Fig. 2 to that shown in Fig. 3, the resistance offered by the counter portion of the shoe to the lengthwise thrust of the last heel reacts through the bell crank lever, compressing the coiled spring 48 to reduce the lengthwise thrust of the last heel, at the same time swinging the abut-- ment plate 50 outwardly so that by the time the parts reach the position indicated in Fig. 3, the abutment plate 50 will overlap the edge of the shelf 52 to a slight extent only. The abutment plate 50 will contact with the shelf, in the illustrated adjustment of the abutment plate, at a point in the last pulling operation before the bottom of the last heel. clears the top of the shoe counter and when the forepart of the last will begin to exert substantial, and what at times has proved to be injurious, strain upon the forepart of the upper approximately at the throat of the vamp or ball portion of the upper at for example, the point indicated at X in Figs. 3 and l. When this point is reached, the contact of the rigid, unyielding plate 50 with the shelf 52 will arrest positively further. thrust-relieving compression of the spring :48 and will momentarilyand substantially augment the lengthwise thrust of the last heel against the counter portion of the shoe, relieving very substantially the pressure against the throat of the vamp by giving the last a substantially increased lengthwise component of movement as illustrated in Fig. i. The rearward swinging ,movement of the bell crank lever effected by engagement with the plate 50 and shelf 52 will cause the abutment plate 50 to swing outwardly and over the edge of the shelf, as suggested inFig. a, so that the period during which the length wise thrust or" the last heel is augmented, is substantially momentary only. As soon as the edge of the abutment plate 50 clears the edge of the shell 52, the lengthwise thrust of the heel against the counter is relieved and with the clearance thus effected between the forepart of the last and the throat of the vamp (see Fig. 4) the last may now be further withdrawn downwardly and rearwardly from the shoe by the normal operation of the machine, without imposing injurious strains upon the shoeparts. The coiled spring 48 which has been compressed in the earlier portion of the last pulling operation, is effective as soon as the bottom of the last heel clears the top edge of the shoe counter to accelerate the lengthwise movement of the last, as suggested in Fig. 5 of the drawings. In the event a high shoe is being operated upon, as indicatedin dotted lines of Figs. 2-5, the acceleration of the lengthwise movement of the last through the coiled spring 48 is of decided assistance in overcoming any additional resistance offered by the back stay portion of the top of the shoe which, in the usual operation of the machine, is folded back by the operator in mounting the last upon the spindle or heel The coiled spring 48 is useful in reducing the lengthwise thrust of the last during the early stagesof its removal, during which time maximum strain is exerted against the parts of the shoe, and is useful also in accelerating the lengthwise movement of the last after the bottom of the last heel has cleared the top of the shoe counter. It is, however within the spirit of the present invention, to dispense with the coiled spring 48 and to adjust the unyielding abutment plate 50 to augment the lengthwise heelward thrust of the last at variably predetermined times in the last pulling operation. For example, it is possible, by adjustment of the plate 50, to

7 cause augmented heelward thrust to the last at that time in the last pulling operation when the bottom of the last edge has cleared the shoe counter, or, so to adjust tlib abutment plate as to cause augmented heelward thrust of the last prior to this point as, for example, to relieve the strain against the forepart of the shoe upper in the manner previously described.

In the operation of the illustrated ma chine, the last with its shoe is mounted upon the heel pin 24 and is swung upwardly by the operator to position the shoe for co-operation with the counter grippers. When this has been done, the treadle 10 is actuated to start the power operation of the machine.

As the cam shaft 12 begins to rotate, the

counter grippers are closed upon the shoe and then the thrust bar 38 is actuated to depress the plunger 30, first cramping the heel pin in the last and then pulling the last downwardly and rearwardly from the shoe, the spring 48, which is preferably employed, acting to reduce the initial lengthwise heelward thrust of the last against the shoe counter and the abutment plate 50 subsequently acting to increase the lengthwise heelward thrust of the last at the point in the last pulling operation predetermined by the adjustment of the abutment plate 50, after which the last is completely removed from the shoe, the carrier arm 26, dropping by gravity to the position shown in Fig. 1 and the counter grippers opening to release the shoe from which the last has been pulled, at which point the machine is automatically stopped. The pulled last may now be re moved from the heel pin and the machine is ready for operation upon the next shoe and last.
