TURN-SHOE IRE-FORMING MACHINE.

Specification of Letters Patent.

Patented Dec. 22, 1914.

Application filed April 27, 1909. Serial No. 492.489.

To all whom it may concern:

Be it known that we, ARTHUR BATES and HAROLD E. Coorsn, subjects of the King of England, residing at Leicester, in the county of Leicester, England, and Norwich, in the county of Norfolk. England, respectivelv, have invented certain Improvements in Turn-Shoe Re-Forming 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.

This invention relates to improvements in machines for re-forming or otherwise operating on boots and shoes, and has particular reference to the manufacture of what are known in the art as turn shoes. A turn shoe is one in which the upper and the sole are sewn together with their wrong side outermost, the shoe subsequently being turned, to bring its right side outermost, either by hand or upon a machine. This operation of turning the shoe has the etfect of distorting its shape considerably, so that it is customary, before anv further operations are performed upon the shoe, to place the shoe upon a last and to beat and rub it with a hand tool to re-form it, i. e., to return it into its proper shape.

A special object of the present invention is to perform this re-forming operation in a better and more expeditious manner than has been possible heretofore and. accordingly, one feature of the invention is the provision of a machine for reforming turn s qpmprising in combination means for stflefacifing the boot and means which by g the sole not only re-forms it, but s 'm it so that it can retain the boot in approximately the form into which it was stretched The means for stretching the upper may be an expansible jack of appropriate size and shape upon which the shoe is placed and which is then expanded, either by hand or power, to stretch the upper and cause it to conform to the she of the jack. The jack may be expanded in a yielding manner to obviate danger of injury to the shoe.

In a construction wherein the jack is expanded and contracted mechanically a con.- venient: arrangement com rises a clutch mechanism that'automst cn stops the com traction 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 stretched.

The sole molding means may comprise any suitable beating-out device, such as a roller between which and the jack there is provision for relative motion so that the roller may act upon the sole of the shoe on the jack and rub it into shape. Preferably. the roller is rotated by connections from any suitable source of power and it may be pro videdwith ribs or projections to etiect a beating as well as a rubbing action upon the sole.

In a convenient construction the roller is movable by hand to act upon the work and there is a support for holding it in its inoperative position, anv suitable driving connections being provided to convev motion to it from the machine of which it forms a part or from any other source of power. Convenientlv, these connections can be arranged so that when the roller is nlnced upon its support it is automaticallv disconnected from the source of power, and conversely, when it is removed from the support into operation upon the work the counection with the source of power is e tablished. Advantageously the connections may be flexibleor may be made telescopic or otherwise variable in length so as to co npensate for variations in the height of the sole upon the jack'due to the spring of the shoe.

Another feature of the present invention is the provision of a machine for reforming boots and shoes comprising in combination an expansible jack, a last support, a roller. and connections between the roller and its driver constructed and arranged to permit the roller while being driven to be brought at will into operative relationship either with the jack or with the last support.

It is obvious that this invention is applicable to other machines than machines for re-forming shoes and the several features of the invention, including those special once before mentioned and others which havntodo with the general utility of the maohimt: mdoslso/ certain more impoi-tantdetails-olfconstruction and combinations oi-pom-will appear more fully in allowing description of chine. Fig. '2 is a left side elevation.

the illustrated embodiment of the invention, reference being had to the accompanying drawings.

Figure 1 is a front elevation of the ma- Fig. 3 is a detail of Fig. 2. Fig. 3 is a. vertical section on the line 33 of Fig. 1. Fig. l is a front elevation. partly in section. and on a larger scale showing connections for driving the heating-out device. Fig. 5 is a detail of Fig. i. partly in vertical section at right angles to the plane of Fig. l.

The frame 2 of the machine includes two columns 3 and i. the former of which supports an expanding jack formed. as shown best in Fig. of relatively movable arms carrying the fore part and heel portions of a shoe form. The fore part is shown as supported directly by the column 3. while the heel part is supported bv a lever 5 which is fulcrumed at 6 to the column and extending downwardly into connection with means for actuating it to move the lever from and toward the fore part for distending lengthwise a shoe which may have been placed upon the jack or form when in its contracted position. This 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. The 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 block. The block and the eye are bored transversely to receive a rod 8 which is screwed into aboss formed on an eccentric strap 10 which embraces an eccentric 12 on a shaft 14. The shaft is turned in bearings in the frame by a gear 15 meshing with a gear 16 having onehalf 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 eccentric rod 8 so that the heel part of the jack will be thrust yieldingly when it in'stmtchin the shoe and the rod. which ismdnced w ere it extends through the lever, and has a shoulder at 20 through which it actuates the lever 5 positively in the direction for contracting the jack. A spring 29 encircles the rod 8 on the right hand side and the force for expanding the shoe is. therefore. transmitted throu h this spring to the lever. The tension 0 this spring is controlled by a. hand wheel 24 threaded on the rod 8 and located in convenient position to be manipulated by the operator at any time to change the tension of the s ring and thereby the orce with which the s 0e 19 being distended; for example, this hand wheel may be manipulated whilb 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 tliniiir ished after the automatic operation of the Jack. The eccentric rod 8 also is pl'UYlllU'l with a hand wheel 25 by which it may be screwed more or less into the boss of the eccentric strap 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 dili'erent sizes. This provision renders unnecessary such frequent changes of the parts of the form or jack as would otherwise be required for lif ferent sizes of shoes The pinion 16 or the portion of shaft carrying it is connected to the main ilrivinu shaft 18 by a clutch which may be of 1lll suitable form so arranged that when the pinion has made a predetermined num er of revolutions said pinion will be automatirallv disconnected from the driving shaft. If the clutch is arranged to cause the pinion to stop at the end of one complete revolution the lever 5 will make one movement -as. e

for example. to expand the jack and lis tend the shoe-and then come to rest ith the shoe in distended condition. and at the next actuation of the machine the lever will be reversely moved and come to rest with the jack in contracted position. If the clutch arranged to give a plural number of rotations to the pinion 16 the lever 5 will re peatedly move the heel part of the form away from the fore part for rapidly expanding the jack and distending the shoe. The clutch will of course be arranged to cause the machine to come to rest with the shoe in distended condition. Each alternate actuation of the machine will preferably cause a single rotation of the pinion i l to actuate the ]ack from an expanded to a ontracted condition. A clutch controlling llC' vice 30 is shown in Fig. '2 arranged to moperated through a rod 32 depending from the hand lever 3i fulcrumed at 6 and whi h is normally held in the position shown ii a spring 35. As has been earlier suggested. it is contemplated that the shoe which has been distended by the expanding jack vlll stantially to its normal shape and size ll1lll be treated to smooth and shape it so that it will have the desired appearance when re moved from the jack. It is found that in makin shoes of very light or very stretch) stock t e upper is distended too much if the shoe is thus distended or otherwise treated while it remains on an expanding jacl; in which. as in the construction above described. the expansion is effected through a spring which continues to exert expanding force while the jack is at rest, as in Fig. 1. To prevent this dificnlty in making such light or stretchy shoes the hand wheel 2 t. controlling the Spring 22, may be adjusted to relax the tension of that sprin or alternatively means may be provide for reslstin the action of the spring while the shoe is ield in distended condition and reventing further expansion of the jack. or this purpose an eccentric 36 15 shown as mounted in the column 3 in front of the lever 5 and provided with an operating lever 38 by which it ma v 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 desired to use it as a stop for limiting the automatically efl'ected expansion of the jack or the eccentric may be turned down to revent further expansion of the jack and distention of the shoe while the shoe is being treated on the expanded jack. The operating lever 38 has a spring plunger 30 for frictionally engaging a plate *0 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 ill is depressed for restarting the machine to contract the jack, to spring under the operating lever 38 and in the upward movement at said bar 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 0 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, -16, the former of v-hich 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 of the shaft 50 is tubular and tcle scopes a dependin shaft 5'3 having a toothed collar 51 a apted for engagement with a recessed collar 55 on the shaft 50 for clutching the two shafts together. The sha ft 52 is connected by a ball and socket or other suitable joint with the lower one 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 58 mounted in a frame 60 and connected by beveled gears with a shaft 62 upon which is fast a beating-out roll or other suitable tool 64. The frame 60 or extensions of the shaft 62 carried therein are pro ided with handles 65 by which the roll inav be liftedand moved over the work nhile it is being rotated through the connections described with the driving mechanism. The machine is provided with a bracket conveniently arranged to receive the roll when the roll is not to be used. The bracket is so located that in placing the roll in it the extensible shaft 56, Wis drawn out and the collar 54 is lifted to withdraw its projections from the recesses in the collar 57 and thereby disconnect the shaft= and so that the shaft 5-2 is not rotated by the shaft .70. When the roll is lifted From itssupporting bracket and brought into po ition for operating upon the shoe the Ii-- lance between it and the frame of the rum chine is shortened scliicientlv to alto".- the clutch members Si. .33 to reugnge and thereby cause the roll to be driven -xh'zlc it is in position to treat the shoe. spr ng arranged between the members ST or the extensible shaft to allow variations in [he norking position of the roll as it is !!.r|='.=\l over different portions of the shoe. Tl-=- rlriving connection between the shaft and the shaft 56 may convcnientlf. uiltu'isc a ball formed in the lower end of -.l1;: it and held in the socket in the other shaft. said ball being provided with a trans PM.) bar or laterally projecting studs rap able of vertical movement in slots in the gri 'lil nalls. The driving connection l)-'.-t-'-'i the shaft section 7 and the section 55 is gmilarly formed by a hall having :1 t";'ll\"?l'-'l' bar T3 and the frame 60 has dependi g flanges 74. This connection permits. r th n certain limits. :1 free tipping mow-aunt 1 the roll in all directions. The e iming connections allow the roll to be tiitrrl as well as moved forwardlv and hwrl-uqnllv for rubbing or beating down different ortions of the shoe to be treated. Thev also permit a lateral movement of the tor-l to bring it into position to operate upon '1 shoe carried by a shoe support on the s cond or right-hand column 4. It is found desirable sometimes to remove a shoe from the pansible jack after the shoe has horn stretched and to apply it to a non-expansi ble last or support such as that sh n on the right-hand column. The shoe is than beaten out by the use of the roll -l.

In the use of the mach ne the shoe afiplied to a jack when the latter is cont a tcd--that is. when the heel part is posit oned closely adjacent to the fore part bv the i-ngagement of the shoulder '20 on the era-0Tb trio rod with the co iperating portion f the lever 55. At this time the gear to r l be disconnected from the driving mechani m and the beating roll 64 will rest n bracket 70. as shown in Fig. 1. ith the clutch members 54, 55 disconnected. The shoe will have been turned right s de out before being applied to the expansible m and to start the machine the operator w ll depress the controlling lever 34-. whercbr the eccentric will be actuated to rock the lever 5 yieldingly through the spring '29 as many times as the clutch is arranged for and will come to rest with the lack in the position shownin Fig. 2 in which t holds the shoein distended cond tion. The rulibing roll or heating device isthen lifted from its support and while being moved into operative relation to the shoe. it be comes automatically connected with its driving mechanism by the descent of the clutch member bl 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 pres sure as in his judgment is required for beatingout the shoe. This operation upon the shoe sole reforms it or shapes it and stitfens the sole so that the sole assists substantially in maintaining the relatively tlexiiile 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 jack the operator rgain depresses the controlling lever 3i and the machine comes to rest with the heel piece ro ked toward the fore part of the divided last or form so that the shoe can be readilv stripped 0a the jack without distorting its shape. The shoe may then be permitted to dry on a rack for making permanent the shape given to it on the jack.

If the shoe under treatment at any time is being stretched too much or too little the tension of the spring 22 will be adjusted by the hand wheel 2% and if it is desired to prevent the shoe from being distended more by the tension of the spring '22 during the heating-out operation on the shoe sole. the eccentric 36 may be positioned as shown in Fig. 2 to lock the lever 5 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 of the jack is preferably provided with a sole plate which extends forwardly to bridge the space between the heel piece and the fore part whereby the expanded jack presents a continuous sole portion to sustain the sole of the shoe for the operation of the beating-out device thereon. The front portion of the plate is thin and beveled so that there is no abrupt shoulder at its end. The plate is preferably of resilien! 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 fore part.
