1910. Serial No. 551,280.

To all whom it may concern Be it known that I, ERASTUS VVoonwAnn, a citizen of the United States, residing at Somerville, in the county of Middlesex and State of Massachusetts, have inventedan Improvement in Sole Laying and Leveling Jacks, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

Theinvention herein to be described relates to machines for treating the soles of boots .and shoes, and more particularly to laying and leveling machines.

The present application is a division of a prior application, Ser. No. 367,912, for sole laying and leveling machines, filed April 13, 1907, now Patent No. 958,057, and the aims and purposes of the invention herein to be described are to provide a jack and its controlling and positionin means so that the shoe may be jacked at t e commencement of the laying or leveling opera-- tion and may be automatically unjacked at the conclusion of said operation that the shoe may be presented to the operator in readiness to be removed from the jack.

The above generally stated objects and others which will hereinafter appear will best be understood from the following description and accompanying drawings of one form of means for carrying the invention into practical effect.

In the druwings:-Figure 1 is a side eleration, partly broken away, of a machine embodying one form of the present invention; Fig. 2 is an elevation and enlarged detail of the stationary cam and cotiperating rotary cam that cooperate to impart suit-- able movements to the jack slide to position and present the jack to and from operative relation with the form; Fig. 3 is a left hand elevation of the jack to show the mechanism for jacking and automatically unjacking the last and its shoe; Fig. 4 is a general plan view of the jack re resented by Fi 3; and Figs. 5 and 6 are etails of the jac ing mechanism, Fig. 6 being a section on line 6--(l, Fi 3.

As pointed out in Patent No. 958,057 of which the present is a division, the machine may be provided with a plurality of work supporting jacks and cotiperating the projecting heads of forms, two of such jacks and their cooperating forms constituting a twin machine, but each of said jacks and its form, however, being entirely independent of the other.

Referring to Fi 1, the machine is provided with suitabe side frames 3, having forwardly extending lugs 4, apertured to receive the outer vertical ide rods 5. The heads of these rods exten through the upper frame lugs 4 to receive the stationary cross head 6 and have nuts 7 threaded upon said rods. The bases of said side frames are similarly tied together by a bottom girder 8 connected to the lower end of the ide rods 5 and to the frame by nuts 9, T ig. 1, said bottom girder having a }pair of rearwardly extending side arms t at are bolted to the side frame at 10, Fig. 1.

Referrin to Fig. 1, the jack is represented as. isposed opposite an oscillatory form 2, the combined movements of the jack and form cooperating to lay the sole of a shoe S mounted upon said jack. Said form 2 has a mold face, shaped in substantial accordance with the shoe sole to be treated.

Thejack is carried on a jack slide 12, Fig. 1, mounted to slide horizontally on a table 11, which in turn is mounted to slide vertically between the guide rods 5, as in said prior patent. The table 11 is carried upon a spring 13 seated at its lower end upon a cross head 14 mounted to slide freely upon said guide rods. Within said spring is a rod 15, secured at its upper end to the table 11, said rod depending through the cross head 14 and having threaded upon its lower end a nut 16, Fig. 1, by which to limit the separation of said table and cross head. The normal tension of said spring may be varied, at will, by a hand nut 17 threaded upon the upper end of said dependin rod 15 and against which the upper end o said spring is seated, as in said prior atent.

The cross head 14 is carried y a pair of vertical links, as pointed out in said rior patent, pivotally connected at their ower ends, as at 19 to the front end of a horizontal lever 20, Fig. 1, fulcrumed upon a horizontal pin 21 in the bottom girder 8. The rear end oft-his lever is connected by a in 22 to a lever 23 standing beside it, the rent end of the latter, Fig. 1, being fulcrumed o'a' the outer projecting'eiid oft-he pivot-pin 21. The movement of this lever vating the'table supporting spring 13 and lifting the jack carrying table 11 to verti'-.

call present the jack to the form 2, as will be c ear.

The table eleyating lever 23 has jointed to it, at 24, an upright operating lever 25, supported at its upper end by a swinging link 26, connected with the frame. Between its ends, said upri ht operating lever has a roller stud 27 w ich underlies a cam 28 on the face of a wheel 29, fast on a horizontal shaft 30 mounted in the frame. This wheel 29 is geared to and driven by a pinion 31 on an up er shaft 32, also 'ournaled in said frame. his upper shaft as a gear wheel 33,-driven by a pinion 34 on the main drive shaft 35 of the machine, rotation of which, through the mechanism and cam described, causes ap ropriate elevation and depression of the jac carrying table.

It is desirable that the jack carrying slide be thrown forward after the table is depressed, and the present invention contemplates means to this end and means to automatically unjack the shoe as it moves into position to resent the jack for convenient removal of the shoe and for the a licat-ion of a new shoe, after which said sh e should be drawn into the machine for presenting it to the laying or leveling form.

For moving the jack out and in there is rovided the following mechanism: At its inner face the gear wheel 33 described is provided with a cam 36, Fig. 2, opposite which is a somewhat similar, ut stationary cam 37, bolted to a vertical bracket 38 at the rear of the machine. The lower end of this bracket is formed to rovide an intermediate or central bearing 3d Fig. 1, for the lower shaft 80, already described. The movable and stationary cams 36 and 37 described are provided respectively with facing cam grooves to receive respectively the o positely extended rollers 40, Fig. 2, carrie by the hubbed head 41 of a horizontal actuatin rod 42, pivotally connected at its front en Fig. 1, as at 43, with the jack slide 12 referred to. The stationary cam 37 which receives the inner roller 40 of said actuating rod acts as a guide to direct the movements of said roller, and hence to determine the movements of the connected jack slide, while the groove of the rotary cam acts u on the opposite roller to produce the desired movements, as in said prior patent. The stationary cam 37 is of general 8 shape and is ]provided at its opposite ends with movab e switch tongues 44, 45 mounted res ectively on short shafts 46, 47, which at t eir outer ends have operating arms 48 acted uponjby springs 49, which tend to retain isaid tongues normally in their full line posit ion",F ig.2. These. positions are made adjustable by stop screws 50. Spring butters are provided at 51 to cushion the spring actuated movements of said tongues. The

cam 37 is also provided at its opposite ends with recesses or ockets 52, 53, each adapted to receive the ro ler 40. When the movable cam 3tlis rotated, it causes the roller 40 on the opposite side of the head of the slide actuating rod 42 to be moved to the left, Fig. 2, causing said roller first to be moved directly to the left to clear the pocket 52, and then to be deflected by the tongue 44 up and along the upper run of the cam groove until it reaches the point thereon marked 54, Fig. 2, which is nearest to the center of the rotary cam. At this moment. the turning movement of the rotating cam brings into position to act upon its roller a concentric portion of its cam groove, marked 55 in Fig. 2, with the result that when the stationary cam roller 40 reaches the point 54 referred to, thus drawing the jack slide inward or to the left for substantially one half its stroke, the action of the said concentric part 55 of the rotating cam produces a pause or dwell in the move- 9 ment of the roller 40 and the jack slide, during which dwell the high part of the cam 28 may depress the jack elevating arm 25. which acts to elevate the jack table and bring the shoe on the jack securely against the opposed form above it. After this has taken place, continued rotation of the cam 36 causes a resumption of travel of the roller 40 in the stationary cam until the limit of its travel at the left, Fig. 2, is reached, said roller engaging the switch tongue 45 and depressing it so that it may direct said roller into the pocket 53, after which said switch tongue springs back into its normal full line position. At this point the roller 40 has com leted the inward move ment of the jack sli e, whereupon continued rotation of the cam 36 reverses the movement of the roll, causing said roll 40 now to be withdrawn from said pocket, the now elevated switch tongue 45 deflecting said roller down and along the lower rotary run of the stationary cam to its supporting position. On its return movement said roller 40 and its connected jack slide are caused again to dwell at the point 54, Fig. 2. corresponding nearly, but not necessarily, to the point 54 at which it pauses on its inward movement, the roller 40 at that instant bein engaged by another concentric portion. his return pause or dwell gives opportunity for the cam 28 to drop the jack from its form preparatory to continued outer movement of the jac into shoe rcmoving position, the switch tongue 44 yieldturn andjthen torise to itsfull line position.

The ="desc'ribed-;arrangementof rotating and stationary: cams 1s 'ty cal of one form of means to secure the-sh lag-movement of the ad: to.and., from its position beneath the orm, and so far as the present inven tion is concerned, any appropriate means ma be employed for moving the jack to an from such position, it being understood that the invention hereinafter claimed is not restricted to any particular means for this purpose.

The stationary cross head 6 is provided with hangers 56 for the supporting shaft 57 on which is mounted the oscillatory form carrier 58 to which the frame is secured.

Reference has been made to the fact that the form and its carrier are mounted for oscillatory movement produced at predetermined times in the operation of the machine. To secure this movement the-outer side of the oscillatory carrier 58 is provided with a segmental gear 94, secured thereto by any suitable means, as bolts 96. The teeth of this gear are in mesh with a bevel gear 97, at the ead of a sleeve 98, loosely mounted on the adjacent ide rod 5, the lower end of said sleeve having a gear 99 in mesh with a horizontal rack 100, Fig. 1, carried at the side of the jack slide 12.

In operation the horizontal movements imparted to the jack slide throu h the actuation of the rod 42 reciprocate t 1e rack 100 to oscillate the gear 99, and thereby the carrier 58 and its form 2. This oscillator movement is effected simultaneously with and corresponds to the movements of the jack slide, so that when the jack slide is brought to rest or has a'dwell in its movement, there will be a corresponding dwell or rest in the movement of the form.

The form 2, of course, has a molding face adapted by its contact with the sole to mold the same to the desired shape or style, said face being complemental to the desired shape of the shank and forepart of the shoe. In the operation of the machine, as the jack is drawn by the action of said cams 30, 37 inwardly beneath but clear of the form, the latter is swung to bring it into the position shown.

A detailed description of the operation of moving the jack toward and from position with respect to the form will not be necessary herein, as the same is set forth in full in said prior Patent No. 958,057, and,- moreover, the particular movements characterizing this feature of the construction are not necessarily essential to the present invention.

In operatin upon shoes of difl'erent sizes and widths, w ile it is usually necessary to chan e lasts for every change in size or widtfi of shoe, it is obviously inconvenient to change the form so frequently, not only becauselof the greater bulk of the form and the 'difliculty. and loss of time inmaking the change, but principally because of the great cost involved in roviding aform for each sizeand width.-- t is a matter of individual judgment and preference how many sizes or widths of shoes-shall be'acted upon by one form. .It has been found convenient to use, say three sizes of forms, and it has been found that even in the best rades of shoes the r uired quality of wor may be performed t ereby u on all the various sizes and widths of s oes, when a proper jack is providedtherefor, whichproperly presents the shoes to 'the form. In providmg a jack to secure this result, that is, to present each jack in predetermined position relative to the form, advantage is taken of the fact that the variations in length of the difl'erent sizes of lasts may be said to be divided between the toe and heel at either side of the ball line. This ball line, therefore, may be selected as the invariable point of reference to which all lasts may be brought by the jack, which latter is made adjustable so as to bring the ball lines of all shoes mounted thereon always into position to provide one invariable or predetermined position of the ball line relative to the form, whatever be the length of the last. jack comprises a sli ing carriage 102, slidably mounted on the jack slide 12 and hav ing at its end a suitable support 103, Fig. 3, for an adjustable, pivoted last block and its heel pin 104, upon which the last is mounted in the usual manner. At its front end this sliding carriage 102 is provided with pivoted sup )orting arms 105 for an adjustable pivote toe pad 106, upon which the toe of the last or shoe mounted thereon automatically seats itself and is supported. The jack slide is provided with a pivoted heel clamp or gage 107, which, together with the support ing arms of the toe pad. are simultaneously moved to predetermined size positions for the size of shoe to be operated upon by an adjusting handle 108, Fig. 4, and its connected mechanism. A scale 109, Fig. 1, is also provided for determining the position of said handle and the corresponding or appropriate size positions of the heel gage and toe support. The position of the heel gage determinately fixes the position of the ball line of the shoe when the jack carriage is moved to bring the heel or counter of the shoe into engagement therewith. as in my application, No. 326.008' filed July 1?, 100 now Patent No. 966,506. For sliding this jack carriage 102 rearwardly on the jack slide to bring the counter of the shoe into the desired size position, and for depressing the toe of the shoe upon its supporting pad automatically to seat the same thereon and also for jacking the shoe in position determined by such adjustment, suitable mechanism is provided," which, as shown in the present form of the invention,-is operated by starting the machine. The unjackin and reverse movementsof the shoe or jac are effected automatically, leaving the jack in its front, shoe-removing and receiving osition on its supporting table 11. hese mechanisms and movements will now be described.

As hereinbefore noted, the carriage or saddle 102 sustains both the toe and the heel end of the last.and the longitudinal movement of the carriage or saddle on its slide 12 is that which brings the last always into the one invariable position as determined by the positioning member 107 against which the heel end of the shoe or last is brought by sliding movement of the carriage or saddle. This movement of the carriage or saddle in a direction toward the positioning member is also utilized for jacking the shoe or last, and during the jacking of the last, the last pin is first swung forward toward the toe support, thereby to measure or come to a bearing in the socket in the last, and then by a further movement to jack the last, as will presently appear. In order to thus jack the last by this movement of the saddle, the last block has depending therefrom an arm 76 forked at its lower end to embrace a pivot block 77 on the upturned end of the horizontal actuating slide bar 79, Figs. 3 and 6, which by its movement relative to the slide operates to give the required movement to the last pin. The movement of the actuator slide-79 to give the last pin its movement, first to measure the last socket and then to jack it, is secured in the present embodiment of invention by forming on the actuator slide 79 a horizontal rack 84, see Fig. 6, the teeth at the under side of which mesh with the pinion 83 fast on a short horizontal arbor 82 journaled in the support 103, and the arbor at its outer end carries frictionallv the pinion 81 which in turn meshes with the stationary rack 80 on the slide 12. Thus, as the carriage or saddle slides inward to carry the. shoe into operative position, the pinion 81 will run on its rack 80 and rotate said arbor 82 and its inner pinion 83, thereby to cause the inner rack 84 to overrun the carria e or saddle, and, by its relative movement iiiereto, to cause the last block arm 76 to be turned to tip the last pin forward to engage with the walls of the pin socket in the last and depress the toe of the last lightly upon the toe support 106. This movement of the last pin is only preliminary to cause it to measure or to be brought li htly into contact with the pin socket wall 0? the last, the friction pinion 81 sliding on its arbor after this preliminary contact is obtained, so as not to firmly jack the shoe at this time.

The toe support 105 and the positioning member 107 are operatively connected to be swung toward and from each other by a suitable hand'device, substantiall the same as fully described in my prior atent No. 966,506, to which reference may be had, such parts not being herein described in detail as they are described and claimed in the said prior application.

The jack and its carriage having been moved backwardly to bring the rear portion of the shoe or last against the ositioning member and to reliminarily tilt the last pin, as hereinbe ore described it now becomes desirable to firmly and finally clamp or jack the shoe upon its support, to which end suitable jacking means are provided, these disclosed in the present case being substantially the same as the similar means shown and described in my prior Patent 966,506, and comprising a rack 232 formed on the outer end of the horizontal actuator slide 79, Fig. 5, referred to as supporting the slide block 77. This rack is adapted to move by a pawl 233, Fig. 5, formed as a bell crank and pivoted atits elbow, just below the inclined rack 101 which locks the toe rest, on a crank pin 234 and on the horizontal shaft 118 to which the jacking lever 122 is secured. The short depending mm 237 of this pawl lever 233 normally bears against a sto pin 238 which holds its horizontal arm e evated out of engagement with the rack 232. In turnin the operating handle of the jacking lever inward, however, the crank pin 234 is turned down and inwardly, causing the pawl to engage the rack. and, by further movement of the handle in the same direction, push said rack rearwardly and cause its vertical arm to carry the pivot block 77 with it and positively tip the heel pin 30, all substantially as fully described in said prior Patent No. 966,506.

Itis to be understood that while the particular means herein described for n-eliminarily tilting the last pin and then for finally jackin the shoe or further tilting the last pin are cscribed as a convenient form of mechanism for jacking the shoe, the invention is not circumscribed by these details, but any form of jacking means may be employed within the true scope of the invention.

Referring to Fig. 3, the mechanism for moving the jack carriage 102 reamvardly upon and relative to the jack slide 12 for positioning the shoe with respect to the positioning member 107 and for preliminarily jacking the shoe comprises a rocking arm 110, loosely mounted on a stud 111 suitably journaled on the jack supportim table 11. Also mounted on this stud and behind the arm 110 is a bell crank lever 112, the short horizontal arm of which is connected by a vertical link 113 with the starting treadle 114, which extends forward to present its tread within ready reach of the op'eratives foot. The vertical arm 110 is connected by a Spring 115 with an ear 116 on the inner en of the'short arm of the bell crank, so that as said arm' is depressed,'the arm 110, through'said sprin swin to the right to bring its upper end, whie l extendsinward horizontally toward the jack into engagement with a roller 117, Fig. 3, loosely mounted on the jacking shaft 118 of the ack carriage'102. The inward swingin movement of this arm, throu h theaction 0 said roller 117, slides the jac inwardlv or'rearwardly to bring the counter of the shoe into engagement with the heel gage 107, which positions the adjusted shoe su ports to present said shoe in its predetermined size position relative to said form. The jacking of the shoe in this position, or, to express it differentl the de ressing of the toe firmly upon t e toe pa is effected by rotating the jack shaft 118 ositively, that is, to the right, Fig. 3. This, of course, may be done by hand, but as here shown this movement is roduced by the action of the'inturned end of the bell crank arm 119 on a roller 120, pivoted'at 121 on the jack operating lever 122 which swings said lever rearwardly to rotate the jacking shaft and jack the shoe.

Upon starting the machine by the depression of the startin treadle, the link 113 is depressed and the ell crank is oscillated or rocked to swin the jack carriage positioning arm inwar to cause engagement, with the roll 117, moving the carriage rearwardly until stopped by t e shoe counter bringing up against the heel gage 107 which, being in its adjusted size position, presents the shoe in such position. Furth r depression of the link 113 and the short arm of the bell crank 112, however, is then permitted through the action of the spring 115, which yields while the arm 110 remains stationa y. to hold the carriage in its size position. The continued depression of this arm 112 swings its vertica arm 119 also rearward, and brings the head of said arm into engagement with the roller 120 and swings the same also rearward to produce the jacking movement of the last pin to depress and maintain the shoe firmly upon the toe support.

To look the carriage in its predetermined size position to prevent displacementthereof after the treadle has been released, there is provided a pair of spring pressed pivoted pawls 123, Figs. 1 and 4, which are adapted to engage the teeth of a rack 124 on the side of the carriage and which hold it in the position upon the jack slide 12 to which it ms been moved by the action of the arm 110. These pawls lock the jack carriage against reverse movement until the jacking shaft is turned in the reverse direction, to the left Fig. 3, to unjack the shoe, when a .be unjacked, picks u By this swinging innermost position,

projectionh118 on the jacking shaft acts uponthe ends of the pawlsjto lift them from the rack-12 4.

-The' 'rock'arm 110'and the bell crank arm b'ehindjt are provided with suitable means, here shown as engaging pins 110, 119, whereby-the; bell crank 119, after having returned" far enough to permit the shoe to and also returns the arm" 110 to the left, ig. 3. Thus the jacking lever may be moved-to unjack the shoe while the arm 110 still holds the carriage in place, followin which said arm 110 is -moved to the le t, thereby permitting movement of the carria e 102 to its outer position on the jack slitfe. To produce this outward movement, which moves the shoe forward away from the heel gage, the jack slide is provided at its outer side, Fig. 4, with a horizontal pawl carryim lever 125 pivoted, as at 120, on a vertica pivot pin secured to the jack slide 12. At its inner end this lever 1s provided with a ivoted pawl 127 which is controlled by a s ring 129 and drugs over the teeth of a me 128 on the ack carriage asthe pawl carrying arm of said lever swings rearwardly in the positioning movement of the shoe under the form. Duringthe operation of the machine and in reaching this osition, the pawl engages an adjacent tooth of the rack to prevent relative or reverse movement between them and cause them to move together when the pawl carrying arm 125 is swung in the opposite direction during the forward movement of thejack, as presently will be described. This pawl, however, has a stop arm 130 which extends at right angles relatively to the pawl am; is adapted to engage a stop pin 131 or. the 'ack slide as said lever 125 is moved into t e position shown in Fig. 4 to cause the disengagement of the pawl from said rack as the carriage reaches its outer position. The inner arm of this lever 125 is normally swung toward pawl engaging position by means of a coil spring 132 connecting said arm with a pin 133 on the jack slide. The jack table 11, at a predetermined point thereon, is provided with a vertical in 134 with which the outer arm 135 of saicrlever 125 engages in the outward movement of the jack slide.

In operation, as the jack slide is moved inward, or to the right, Fig. 4, toward its inner position, the outer arm 135 of said lever 125 is drawn by its spring to the left. movement of said lever,

the pawl 127, through the action of its .s ring 129, is swung into engagement with t e teeth of the rae and is caused to drag thereover until the jack slide reaches its the pawl then resting in engagement with the rack and cooperating with the pawls 123 to lock the carriage against return movement during the laying engaging the stationary pin 134, causing the pawl arm of said lever tobe swung to the eft about its pivot 126, and swing, said pawl alsocto the left, thereby to pus said pick carriage outwardly wit its shoe'that vas been unjacked duringithe same outward movement, thus moving t em away from the heel clamp and causing the heel pin to tip to its UPHghtTYIOSltlOH to facilitate removal of the shoe. e said lever 122 is swung to the left, .Fig. 3, automatically to unjack theshoe by the outward or return movement of the jack which'causes the cam extension 122' of said lever, then in its downturned position, to engage the upturned and elevated end 137 o a bell-crank 136, to be described. This rearward swin 'ng movement of the jacking lever, to the Idft, Fig. 1. causes its roller 120 to swin the arm 119 also to the left, during whic the pin 119' picks up the pin 110, to cause movement of the arm 110 away from the carriage roller 117 subsequentto the unjacking of the shoe, and permit the carri to be moved to its outer position on the ack slide.

e bell crank 136, Fig. 1, referred to, is pivotally mounted on the jack table 11 and its horizontal arm is rovided with the up-. turned end 13! which plays in a vertical slot 138 in the jack slide 12, Fig. 4. The depending short arm of this bell crank rests, under the action of gravity, against a pin 139, Fig. 1, horizontally slidable in the table 12. The opposite or rear end of this pin normally on ages the vertical arm of a bell crank 140, ig. 1, pivotally mounted on the frame. The long horizontal arm of this bell crank is provided with a roller 141, riding on the ed e of a tappet cam 142 which, at the conc usion of the laying operation, elevates said arm, cousin the vertical arm of said bell crank 140 to swing outward, and producing corresponding movement of said pin 139 and the depending arm of the bell crank 136. This movement vertical, up-turned end 137 of the bell crank 136 to place it in the path of the cam extension 122' of the jack operating lever, so that as the jack slides outwardly at the completion of the laying movement and after the separation of the jack and form, said extension 122' will engage said upturned end 137 and cause said lever to swing to the right,

Fig. 3, to automatically unjack the shoe.

y the construction hereinbefore described it is apparent that the unjacking of the shoe is effected automatically the jacking bein efi'ected by depression of the starting trea 1e and the unjacking by the outward movement of the ack to a position'of elevates the presentation. I Obviously, the jacking of the shoe might be accomplished by hand manipulation of the handle 122, the jacking lever 119 under such conditions bein dispensed with, if desired; and the unjaciing of the sh under the conditions just mentioned, won d still be efl'ected by the outward movement of the (jack to a position where the operator coul readily remove a shoe from "or place a shoe upon the jack. Furthermore,

the construction described also provides means for unlocking the shoe and moving it away from the heel gage 107 to facilitate its rea y removal when in shoe removing position, and, also, the application of the next shoe to be treated.

The operation of the machine will be clearly understood by those skilled in the art from the drawin and description herein, such parts of t e machine not herein treated being definitely and fully described in the prior Patent No. 958,057, of which this is a division; the invention herein being more particularly directed to the jack and its associated elements whereby many of the operations heretofore performed by hand are effected automatically, such as the unjacking of the shoe as the jack moves to a position convenient for the operative to remove the shoe.

It will also be obvious, of course, that many changes may be made in the details of construction without departing from the invention, the broad character of which is definitely set forth by the claims.

What is claimed is:

1. In a machine for treating boots and shoes, the combination of a supporting frame, a table, a shoe support or jack having a last pin and toe rest and mounted to slide on said table, means for tilting the last pin for jacking the shoe on said shoe support or jack to hold the same for treatment. and means acting automatically to unjack the shoe as the support or jack is moved out ward on said table.
