Specification of Letters Patent.

Original application led April 27, 1909, Serial No. 492,489. Divided and this application iled May 20, 1910, Serial No. 562,494. Renewed October 20, 1914. Serial No. 867,666.

To all 'Lo/rom t may concern.'

Be it known that we, ARTHUR BATEs and HAROLD E. COOPER, subjects of the King of England, residing at Leicester, in the county of Leicester, England, and Norwich, in the county of Norfolk, England, respectively, have invented certain lmprovements in Shoe-Supports for Turn-Shoe Re-Forming and other' Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

rlhis invention relates to improvements in jacks for holding boots and shoes and for stretching the uppers thereof to cause them to conform to the shape of the jack while being operated upon by any suitable finishing tool or instrumentality, or for stretching and shaping the uppers without referencevto any other operation.

rThe invention is shown and will be described in connection with the improved construction of beating and rubbing tool for reforming turn and other shoes disclosed in my co-pending application, Serial No. 492,489, filed April 27, 1909, of which the present application is a division; and while certain features of the jack herein described and claimed have advantages which especially iitthem for use in connection with beating and rubbing tools of the character disclosed in said prior application, and cooperative therewith in securing new and valuable results in the operation of re-forming turn and other shoes, some features of the invention which will be claimed herein, are of more or less general utility in expansible jacks for stretching and shaping boots and shoes.

An important feature of the invention resides in the provision of relatively movable parts to stretch the upper which are moved to expand or contract the jack by power applied through clutch mechanism, that automatically stops the contraction and expansion of the jack in either of its extreme positions, to permit work to be removed from and placed upon the jack, or to be operated upon while it is being stretched.

Preferably, the ack is expanded through a yielding device in order to obviate the danger of unduly7 stretching the shoe while the jack is being expanded, and a feature of the invention in this connection comprises means for changing the tension of said yielding device, either before the jack is expanded or while the shoe is held in a distended condition, in order that the force acting to stretch the shoe may be increased or diminished in accordance with the size of shoe being operated upon, or to lessen the expansive force of the jack for shoes of light or stretchy stock, and to increase it proportionately for shoes of heavier or less elastic stock.

In this connection, another feature of the invention consists in providing an adjustable stop to limit, variably, theamount of stretching movement imparted to the shoe by the movable member of the jack through the yielding device before referred to, which stop acts independently of the means for adjusting the tension of such device.

Still another feature of the invention consists in providing mechanism for causing the jack to expand and contract a plurality of times before coming to rest inan expanded condition. It has been found that by subjecting the shoe to a number of successive stretching movements the upper' is gradually brought to its final shape with less danger of injury to the stock,` and in a more thorough manner, than where the jack expands once only and then comes to rest.

Other features of the invention, including important details of construction and combinations of parts, will be hereinafter more particularly described and claimed.

Referring to the drawings: Figure l is a front elevation of the machine. Fig. 2 is a left side elevation. Fig. 2a is a detail of Fig. 2. Fig.`3 is a vertical section on the line 3-3 of Fig. l. Fig. 4 is a front elevation, partly in section, andon a larger scale showing connections for driving the beating-out device; and Fig. 5 is a detail of Fig. 4, partly in vertical section at right angles to the plane of Fig. 4. Fig. 6 is a detail showing the relative arrangement of the heel part and fore part of the jack and their intermediate sole plate.

The frame 2 of the machine includes two columns 3 and 4, the former of which supports an expanding jack formed, as shown best in Fig. 2, of relatively movable arms carrying the fore part and heel portion of Patented Dec. 22, 1914. y

a shoe form. '1`he fore part 11 is shown ask supported directly by the column 3, while the heel part 13 is supported by a lever 5 which is fulcrumed at 6 to the column and extends downwardly into connection with means for actuating it to move the lever from the fore part to distend lengthwise a shoe which may havev been placed on the jack, a spring 17 which connects the lever 5 with the frame of the machine serving to yieldingly contract the heel part to permit the shoe to be pla-ced on the jack or removed therefrom. '1`his arrangement provides for thrusting the heel part of the form into the relatively substantial heel part of the shoe, thus drawing the forward portion of the shoe tightly about the fore part of the form or jack. rlhe parts of the form are made removable to permit parts to be used which are of appropriate size and style for different shoes to be treated.

The lower end of the lever 5 is provided with an eye in which is held a cylindrical bloclr. The block and the eye are bored transversely to receive a rod S which is screwed into a boss formed on ayblock 10 which is slotted to receive the shaft 14 so as to be capable of a limited amount of.

transverse movement thereon, and supports a cam roll 7 which is held vieldingly in engagement with a suitable operating cam fast on the shaft 1l, by the spring 17. rlhis cam may be so shaped as to effect any desired number of contractions and expansions of the jack before the machine is brought to a stop with the shoe in an expanded condition. As herein shown, the cam is designed to cause the jack to expand twice before coming to rest, and' to this end it is shown as having two high-points or projections 9 and 19, the latter serving to effect the nal outward movement of the heel part, and being preferably of greater height than the projection 9 in order that the movements imparted by the cam to the heel part may progressively increase to thereby gradually stretch the shoe. rlhe shaft 1&1 is turned in bearings in the frame by a gear 15 meshing with a gear 16 having one-half the number of teeth that the gear 15 has and which is driven from the main driving shaft 18 of the machine. The lever 5 is yieldingly connected with the rod 8 so that the heel part of the jack will be thrust yieldingly when it is stretching the shoe bv a spring 22 which encircles the rod and bears at one end against the lever 5 and at its opposite end against a hand wheel 24 threaded on the rod. The force for expanding the shoe is, therefore, transmitted through this spring to the lever. The tension of this spring is controlled by the hand wheel 24 which, as shown, is located in convenient position to be manipulated by the operator at any time to change the tension of the .spring and thereby the force with which the shoe is being distended; for example, this hand wheel may be manipulated while a shoe is held on the jack in distended position and by such manipulation the force acting to distend the shoe may be manually increased or diminished after the automatic operation of the jack. The rod 8 also is provided with a hand wheel 25 by which it may be screwed more or less into the boss of the bloclt 10 to change the normal angular position of the lever 5 and therefore the normal relation of the lever and the fore part of the jack for shoes of different sizes. This provision renders unnecessary such frequent changes of the parts of the form or jack as would otherwise be required for diEei-ent sizes of shoes.

rllhe pinion 16 or the portion of shaft carrying it is connected to the main driving shaft 18 by a clutch which may be of any suitable form so arranged that when the pinion has made a predetermined number of revolutions said pinion will be automatically disconnected from the driving shaft. ln

the arrangement shown a one revolution t clutch of any suitable or ordinary construction is provided, the gearing and timing of the parts being arranged to cause the pinion to stop at the end of a complete rotation and each alternate actuation of the machine will preferably cause a single rotation of the pinion to expand the jack twice and cause it to come to rest in an expanded condition. On the next actuation of the clutch the jack will be moved to contracted position to permit removal of the shoe. ln Fig. the ma.- chine is shown at rest with the cam roll 7 resting on the cam projection 19 in which position the jack is fully expanded. Upon the next actuation of the clutch the gear 1:3 and the cam will be caused to rotate in the direction indicated by the arrow until the roll travels to lowest noint 12 of the cani, when the machine will stop with the jack in contracted position. clutch is actuated the cam roll will pass successively over the projections 9 and 19 which will effect two expansive movements of the jaclr and the machine will automatically be brought to a stop with the parts in the posill tions which they occupy in Fig. 2. A clutch controlling device 8O is shown in Fig. 2 arranged to be operated through a rod 32 depending from the hand lever S/l fulcrumed at 6 and which is normally held in the position shown by a spring B5.

As has been earlier suggested, it is contemplated that the shoe which has been distended by the expanding jack to approximate substantially its normal shape and size shall be treated to smooth and shape it so that it will have the desired appearance when removed from the jack. It is found that in making shoes of very light or very stretchy stock the upper is distended too The next time the 'f much if the shoe is thus beaten out or otherwise treated while it remains on an expanding jack in which, as in the vconstruction above described, the expansion is effected through a spring which continues to exert expanding force while the jack is at rest, as in F ig. 2. To prevent this difficulty in making such light or stretchy shoes the hand wheel 24, controlling the spring 22, may be adjusted to relax the tension of that spring, or alternatively means may be provided -for resisting the action of the spring while the shoe is held in distended condition and preventing further expansion of the jack. For this purpose an eccentric 86 is shown as mounted in the column 3 in front of the lever 5 and provided with an operating lever 38 by which it may be turned into position to limit the movement of the lever in the direction for expanding the jack. This eccentric may be positioned before the machine is started in the event that it is desiredl to use it as a stop for limiting the automatically effected expansion of the jack or the eccentricmay be turned down to prevent further expansion of the ack and distention of the shoe while the shoe is being treated on the expanded jack. The operating lever 38 hasaspringplunger 39 for frictionally engaging a plate 40 to hold the lever in the position to which it has been adjusted. The rod 32 may have a lug 42 adapted, when the clutch controlling lever 34 is depressed, for restarting the machine to contract the jack, to spring under the operating lever 38 and in the upward movement of said rod to turn the eccentric into an inoperative position. By this means the eccentric, after having been used to prevent further expansion of the jack during the treatment of a shoe may be restored to its inoperative position where it will not interfere with the normal expansion of the jack with the next shoe applied to it.

The driving shaft 18 is provided with fast and loose pulleys 45, `46, the former of which has an internal gear from which is rapidly driven a small pinion on a shaft 48 connected by beveled gears 49 with a vertical shaft 50, see Figs. 1 and 3. The upper portion cf the shaft 50 is tubular and telescopes a depending shaft 52 having a toothed collar 54 adapted for engagement with a recessed collar 55 on the shaft 50 for clutching the two shafts together. The shaft 52 is connected by a ball and socket or other suitable joint with the lower end of two telescopic sections 56, 57, of an extensible shaft, which in turn is connected, as shown in Figs. 4 and 5, by a universal `joint with a shaft 5S mounted in a frame and connected by beveled gears with a shaft 62 upon which is fast a beating-out roll or other suitable tool 64. rThe frame 60 or extensions of the shaft 62 carried 56. 57 is drawn out and the collar 54 is lifted to withdraw its projections from the recesses in the collar 55 and thereby disconnect the shafts 50 and 52 so that the shaft 52 is not rotated by the shaft 50. When the roll is lifted from its supporting bracket and brought into position for operating upon the shoe the distance between it and the frame of the machine is shortened sufficiently to allow the clutch members 54,

55 to rengage and thereby cause the rollv to be driven while it is in position to treat the shoe. A spring is arranged between the members 56, 57 of the extensible shaft to allow variations in the working position of the roll as it is moved over different portions of the shoe. The driving connection between the shaft 52 and the shaft 56 may conveniently comprise a ball formed in the lower end of the shaft 56 and held in the socket in the other shaft, said ball being provided with a transverse bar or laterally projecting studs 72 capable of vertical movement in slots in the socket walls. This connection permits an entirely free forward and backward movement of the roll and a limited lateral movement of the roll. The driving connection between the shaft section 57 and the section 58 is similarly formed by a ball having a transverse bar 73 and the frame 60 has depending flanges 74. This connection permits, within certain limits, a free tipping movement of the roll in all directions. These tipping connections allow the roll to be tilted as well as moved forwardly and backwardly for rubbing or beating down different portions of the shoe to be treated. 'lfheyalso permit a4 lateral movement of the tool to bring it into position to operate upon a shoe carried by a shoe support on the second or right-hand column 4. It is found desirable sometimes to remove a shoe from the expansible ack after the shoe has been stretched and to apply it to a non-expansible last or support such as that shown on the right-hand column. The shoe is then beaten out by the use of the roll 64.

In the use of the machine the shoe is applied to the jack when the latter is contracted,-that is, when the lcam roll rests on the low part l2 of the cam and the heel part of the jack is held by the spring 17 closely adjacent to the fore part. At this time the gear 16 will be disconnected from the driving mechanism and the beating roll vsov GAL will rest in its bracket 70, as shown in Fig. l, with the clutch members 54, 55 disconnected. rlhe shoe will have been turned right side out before being applied to the expansible jaclr and to start the machine the operator will depress the controlling lever Se, whereby the cam will be actuated to rock the lever 5 yieldingly through the spring a plurality of times and will come to rest with the jack in the position shown in Fig. 2 in which it holds the shoe in distended condition. The rubbing roll or beating device is then lifted from its support and while being moved into operative relation to the shoe, it becomes automatically connected with its driving mechanism by the descent ot the clutch member 54 into driving engagement with the clutch member 55, whereby the roll is rapidly turned. The operator carrying the roll in his two hands moves it over the shoe into such positions and with such pressure as in his judgment is required for beatingout the shoe. T his operation upon the shoe sole reforms it or shapes it and stiil'ens the sole so that the sole assists substantially in maintaining the relatively Flexible shoe upper in its distended or re-formed condition after the shoe has been removed from the jack. To restart the machine for contracting the jaclr the operator again depresses the controlling lever Si and the machine comes to rest with the heel piece rocked toward the fore part of the divided last or orm so that the shoe can be readily stripped oli' the jack without istorting its shape. rlhe shoe may then be permitted to dry on a rack for makin(7 permanent the shape given to it on the jack. lt the shoe Linder treatment at any time is being stretched too much or too little the tension of the spring will be adjusted by the hand wheel 2l and it it is desired to prevent the shoe from being distended more by the tension ot the spring 22 during the beating-out operation on theshoe sole, the eccentric 86 may be positioned4 as shown in Fig. :2a to lock the lever against further movement or the eccentric may be used to move the lever in opposition to the spring 22 to contract and then reexpand the jack. The heel piece 13 of the jack is preferably provided with a sole plate which extends forwardly to bridge the space between the heel'piece i3 and the fore part l1 whereby the expanded jaclr presents a continuous sole portion to sustain the sole of the shoe 'for the operation oli the beatingout device thereon. rl`he 'ront portion of the plate 75 is thin and beveled so that there is no abrupt shoulder at its end. rThe plate 75 is preferably of resilient material and so positioned and secured upon the heel piece that it will in all positions of the latter hug the bottom face of the tore part.

While have shown and described an actuating cam whose construction is such that it imparts two complete expansive movements to the acl; before the jack comes to rest, it is to be understood that the invention is not limited to use with this form of cam or device for expanding the jack as it is within the contemplation ol the invention to provide any suitable form ot cam or clutch between the power shaft of the machine and the jaclr which will cause the ach to expand the number ot times desired in each operation of the machine.
