Specification of Letters Patent.

Patented Dec. 28, 1915 Application filed April 13, 1910. Serial No. 555,294.

To all whom it may concern Be it known that I, THOMAS G. PLANT, a citizen of the United States, residing at Boston, in the county of Suffolk and State of ll lassachusetts, have invented an Improvement in Shoe-Supports, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

i The invention to be hereinafter described relates to shoe supports, and more particularly to such supports for sustaining a shoe in position while the heel is being treated, although, as will be understood by those skilled in the art, it may be employed for other purposes.

The aims and purposes of the present invention are to provide a shoe support of the general type mentioned, which shall be simple in construction and efficient in properly sustaining the shoe in position for treatment, all of which, and other objects, will best be made clear from the following description and accompanying drawings of one form or embodiment of means for carrying the invention into practical effect, it being understood that the invention is not circumscribed by the illustrated details, but is defined in its true scope by the claims.

An illustrated use of the present invention in connection with an organized machine is afforded by Patent No. 1,107,838, Aug.'18, 1914-, for heel breasting machines, and to this patent reference may be had for detail description of means, such as heel breasting means, for acting on the heel of a shoe sustained by the shoe support which forms the subject of the present application.

In the drawings :-Figure 1 is a front elevation with part of the frame broken away, showing sufficient of a machine for treating shoes to make clear the construction and operation of the present invention; Fig. 2 is a side elevation of the parts shown by Fig. 1; Fig. 3 is a section on the line 3-3 of Fig. 2; Fig. 4 is an enlarged detail view, showing the upper portion of a shoe support and its adjusting means; Fig. 5 is a section on the line 5-5 of Fig. 4; and Fig. 6 is a section on the line 66 of Fig. 4,. r

The machine frame for su orting the operating parts of the machine may be of any usu l or desire ha acter, and herein rep resented as a column 1 having suitable upwardly extending portions 2, Figs. 1 and 2, for sustaining and guiding the moving parts.

These features may be any form and kind suitable to the purposes intended, as pointed .out in said prior application.

Mounted in hearings in the lower portion of the column 1 is the main shaft 5, Figs. 1 and 2, provided with suitable driving means, as the pulleys 6 and 7, both of which may be loose on the shaft, so that when the belt is shifted to the pulley 6, said pulley may run idly without danger of starting the machine even though the machine starting means be operated. The pulley 7,however, as pointed out in said prior application, while loose upon the driving shaft 5, may be connected thereto at desired times to cause one rotation of said shaft, whereupon the shaft may come to rest, all as more fully explained in said prior application, and which, forming no part of the present invention, is not further herein described.

Pivotally mounted at 8 on suitable sustaining lugs 9 at the base of the column 1 is a swinging jack standard or support 10. The swinging jack standard or support 10 projects upwardly and passes through a suitable aperture in the sliding plate 11 which is mounted in suitable guideways in the table 12. The table 12, it will be noted, has an inclined upper face, and so also has the sliding plate 11, the purpose being to cause any chips or scraps that may drop from the shoe during the operation of the machine to pass therefrom and not lodge thereon to the detriment of the working parts. It will be noted that the table 12 and the sliding plate 11 extend for a considerable distance from front to rear of the machine and that the sliding plate practically covers the guide opening in the table 12 when the swinging jack standard or support 10 is either inits front or rear position, as

will presently appear.

secured beneath the table 12 is a yielding bunter or stop 13, Fig. 2, which is adapted to be engaged by a projection or part 14 connected to the sliding plate 11, the construction being such that when the swinging.

jack standard or support 10 is moved from its front to its rear position about its pivotal support 8, the part 14 will contact with the yielding banter 1,3. and bring the part grad the end portion 27 a, if the handle 26 beforceddownwardand ,5 i t -.th ig t. h segm ually to rest, in substantially correct position for the operation of the heel breasting or other means.

The upper portion of the swinging jack standard or support 10, see Figs. 4 and 5, is provided with a recess in which is sustained the jack post 16, the lower end portion of which rests upon a wedge 17. In the present form or" the invention the wedge l7 is preferably formed as a segment and is guided in theswinging jack standard by means-ofa groove 18 which, in cooperation with theside openings in the standard through which the segment wedge passes, atford convenient meansfor holding the segment wedge in proper jack post sustaining position. The lower end portion oi. the jack post 16 maybe provided with a groove, as 19,"Fig. 5, to engage about the upper surface of the segment wedge as a convenient means for maintaining the parts in coacting relation. The segment wedge l? is mounted to swing about-a center on the swinging jack standard, the construction being such that "as the wedge is swung relative to the jack standard and jack post, the latter will be raised or lowered to accommodate the conditions of work, as will be readily understood by those skilled in the art.

means for mounting the segment wedge 17, the swinging jack standard is provided witha lug 20 which sustains a pin 21 which itself affords a pivotal support for the arms22 and 23, the other ends of said arms being appropriately connected at 2st and 25 to the segment wedge, as willbe readily understood from Fig. 4. As a preferred construction the arms 22- and 23 are duplicated, one set being at each side of the swinging Tjack standard, as indicated in Fig. 55, whereby a steady and eliicient swinging support is afforded for the segment wedge 17. Inorder that the wedge 17 may be conveniently and readily moved about its center 21 to properly position the jack post and consequently the work, a handle 26 is provided, said handle being pivoted at 24 to the segment Wedge 17 and, to maintain said handl'ein appropriate position for the operator, below the connection 24 is pivotally connected at 28 to a link 29, the

opposite end of which is pivoted at 30 to the lug 20, the construction being such that as the handle 26is pushed or pulled, asthe case may be, to ad ust the swinging segment wedge 17 to appropriate or desired position,

the link 29 will serve to maintain the handle hand of the regardless of whether the wedge as will be clearly For instance, the indicated in Fig.

operator,

understood from Fig. 4t.

wedge will be moved endwise to the right, and as it thus moves, the link 29 acting on the end 27 of the handle 26 will so alter the path of movement of the handle 26 as compared with that of the segment wedge 17 that said handle will be maintained in convenient position for the hand of the operator, as will be readily understood.

The shoe support and jack of the present invention is more especially designed to support a shoe while on the wooden last for treatment by the heel breasting or other devices, and to this end the jack post is provided with a head block 31, Figs. 4- and (5, which is itself provided with a curved slideway adapted to engage a coacting or complemental guideway in a pin block 8i, from which projects a last pin 35, the construction being such that as the pin block is moved on the head block, it will be appropriately turned in a vertical plane in accordance with the angle desired to be given to the heel breast by the breasting devices.

The pin block i is provided with a recess 57 extending longitudinally thereof in which is loosely contained a spring 58, the ends of which are adapted to engage the slotted end walls 59 of the pin block. Extending upward from the head block 31 are the end pieces which are also adapted to engage the ends of the spring 58, the construction being such that when the pin block 3% is moved in either direction as prescribed in the guideways 32 and 83, the spring 58 will be compressed between the approaching wall 59 of the pin block and the end piece 60 on the opposite end of the head block 31. Thus it will be seen that while the spring .58 normally holds the pin block in position, as indicated in Fig. i, it will permit the pin block to move yieldingly in either direction to properly position the heel, such movement being etfected by the hands of the operator.

As well understood by those skilled in the art, the pin holes of lasts are not always accurately positioned with respect to the last, or are not always accurately formed so that it becomes necessary at times to move the jack post to one side or the other in order to bring the heel of the shoe in proper positionfor treatment. In the present form of the invention this characteristic movement 01 the jack post is provided by forming the jack post 18 with play in the standard, as indicated in Figs. 4: and 5, and providing springs 36 between the jack post and the interior wall of the swinging jack standard, as indicated in Fig. 5. As a convenient means of thus yieldingly maintaining the jack post in position and yet permitting it to be moved sidewi'se to properly position the shoe supported by the jack, said jack post is provided with sockets 37 in which the springs 36 are seated, so that such jack post side .or the as lndicated in Lit Fig. 5, the construction being such that while the post 16 rests upon or is supported by the wedge 17, it may be tilted to one side or the other to properly position the shoe, even though the last pinsocket of the last may not be true or central of the last, there being sufficient play or looseness between the jack post and wedge, and the ack post and walls of the recess 15 to permit such tilting movement of the jack post on the wedge and in said recess, as will be clearly apparent to one skilled in the art. As a means for preventing turning movement of the jack post while still permitting such sidewise adjustment, the surfaces of said jack post at 38 are flattened somewhat and are engaged by blocks 39 on the interior of the swinging jack standard 10, the construction being such that the blocks 39 which may be held in place or adjusted by means of set screws 1-0, Fig. 4;, while preventing rotative movement of the jack post on its vertical axis will yet permit sidewise movement of the jack post for the purposes hereinbefore noted.

W hen the shoe support and jack have been moved to their operative position for the action of the heel breasting or other means upon the shoe. it is desirable that the parts be locked so that the shoe may be positively held during the action of such breasting or other devices. To this end the main shaft 5 is provided with a cam l1 which is engaged by a roll 42 on the arm 43' of the lever which is pivoted at 1-1, the other arm 45 of which is connected at 46, Fig. 1, to a rod or actuator 47, the upper end of which is con nected to an arm 48 secured to a rock shaft 19, substantially as pointed out in the application hereinbefore mentioned. Secured to the rock shaft 49 is a toe 50 which supports the arm 51 loosely mounted on the rock shaft 49 by means of a set screw 52 which passes through a lug carried by the arm 51, the con struction being such that wh an the shaft 49 is turned contra-clockwise, Fig. 1, the toe 50 will. be lowered and the arm 51 will be allowed to descend, substantially as pointed out in said prior application.

Secured to the arm 51 is a rod 53. the lower end portion of which carries a lock 54: which may be substantially as set forth in. said application, or otherwise. Projecting rearwardly from the swinging jack standard 10 is a bracket 55, the upper rear portion of which is provided with a series of teeth which are adapted to be engaged by the lower end of the lock 54 and hold the swinging jack standard or support 10 in rear position, substantially as pointed out in said application.

From the construction hereinbefore described it will be apparent that the swinging jack standard may be moved to and from operatlve position and be locked in operative position by means controlled from the main shaft, and that the jack post carried by the swinging jack standard may be conveniently and readily raised or lowered by means of the wedge so as to properly position the shoe for the action of the breastingor other devices. the handle for thus moving the wedge being appropriately maintained in convenient position for manipulation by the operator. and the wedge itself being preferably swung about a center carried bv the swin9: Eng standard or support. It will also be noted that the jack post, independent of the swinging ack standard, may be moved sid wise relative thereto to properly compensate for any inaccuracy in the last pin socket of the last.
