JACK FOR SOLE LAYING AND LEVELING MACHINES.

Be it known that I, ERASTUS WooDwARD, a

`citizen of the United States, residing at Somerville, in the county of Middlesex, `State of Massachusetts, have invented an Improvement in Jacks for Sole Laying and Leveling Machines, of which the following i f description, in connection with the accom- Wfpanying drawings, 1s a specification, like characters on the .drawings representing like parts.

- The present invention relates to jacks for sustaininga lasted boot or shoe and pari ticularly to jacks adapted to be used i"connection with soleleveling or laying machines rfor sustaining the lasted shoe during the sole-leveling or laying operation.

The invention has for its object to provide a novel form of jack which is adapted to y and shoes, and to so position the lasted shoe receive any one of the different sizes of lasts supported thereby of whatever size that it i will always be situated properly'with reference to the leveling form of the machine to,` insure uniform and accurate work.

l In operating on shoes of different sizes and Widths, it 1sl usually necessary to change the lasts for every change in size of shoe, but it is inconvenient to change the leveling form 'so frequently not only because ofthe greater bulk of the form and the diiicult-y in making the change, but principally because of the great cost involved in providing l a form for each'size and width. I ind that if a jack of a vided to proper y present theJ shoes to the i1 form, it is possible vto level the soles of a defined line of separation between the foreart of the form and the projecting shank. his line of separation corresponds to the ball line of the shoe, so that if a series of shoes of different sizes are to be treated by" a single form or roll, and each of the shoes are brought to a position with the ball line l. of the sole thereof disposed to register with the line of separation referred to, each of the series of shoes, notwithstanding their variation in size, may be properly treated by the Specification of Letters Patent. ,application sied July 1s, 190e. serial No. 326,008.

onerforni or roll. secure the desired results I have takensad-A vantage of the above fact, and accordin ly" have selected this ball line as an invaria le point of reference to which all vlasts must be brought relative to the jack and the said 60,

line ofV separation of the form, said jack being made adjustable for varying sizes of vshoes in such Amanner that it will position an'y size of shoe with the ball line thereof at one invariable-position to register with said corresponding line in the form. y

The invention also comprehends certain novel features of construction` by means of which the shoe is jacked and held inl itsv v Jack-ed position, all as will be more fully hereinafter described and then pointed out in the claims.

In the drawings I have shown a soleleveling machine having one form of my improved jack associated therewith, this form being that which I have selected forthe purpose of illustrating the principle of the ins,

Vention. Y f i Figure l is a side elevation of a sole-leveling or laying machine having my improved jack thereon;A Fig. 2 is an elevationrof the left-hand side' of the jack and its last-supporting and positioningdevices; Fig. 3,v` a plan, and lFig. 4, a front elevation thereof;

VFigs. 5 and 6 are vertical sections taken re-t85 spectively on, the lines 9?-9 and jO-IIG, Fig. 2; Fig. 7 is a longitudinal vertical sectional detail of the -jacking mechanism of said jack. n i

The sole-leveling or laying machine herein illustrated comprises the frame 2 on which is mounted avdriving shaft 8 having suitable clutch mechanism,not shown, for starting and stopping said shaft. This shaft has a gear 36 thereon which ineshes's with and drives a gear 34 carried by a shaft 3L also journaled in the frame. The gear 34 constitutes a crank disk and it has a crank f pin 37 to which is'pivotally connected one end of a pitman or link 38, the other end of which is pivotally connected at 300 to a lastsupporting slide 26 Which'moves back and forth in ways formed in the table 33 of the fiame. The frame lalso supports an oscillatory form 12%l shown diagrairnmaticallyv only 105 in Fig. l, and said form is arranged to be oscillated about its centerofmotion asthe jack-supporting slide 26 is drawn inunder,

the form, said form acting during this operation on the'sole of the lasted slice and laying or leveling the latter as will be ob- VlOllS.

The parts thus far referred to forni no part of my present invention. y

In order to make it possible for a single form 12a to be used successfully with a number of .different sizes of lasts, I have provided a jack which can be adjusted to sustain any size of hist and whichwhen adjusted will always bring one invariable point of ret'erence on thelast, as, for instance, the ball line thereof, in one invariable point. with relation to the jack and the forni so that when the form acts on the lasts of ditt'erent sizes, the portion of the form corresl'ioiiding -to the ball line of the last will always meet and register'with the ball line of the sole of the slice regardless of the size of the latter. This end is accomplished (in the present invention by the following construction: The slide 26 has mounted thereon a carriage or lsaddle 71, see Figs. 2, 5 and 7, having at its rear end a suitable support or standard 72 to which is pivotally mounted at 74A a last block 7 3, the latter hav-` ing extended therefrom the usual last pin 30 upon which the heel of an inverted last 31 is mounted, lthe pin freely entering Ithe socket with which each last is provided, while the top or comb of the last rests on the last The saddle or carriage 71 also sustains the toe rest 2t) on which the toe end of the last is supported, said toe rest being adjustable, and also beingir sustained in such a Kway that it will automatically find .its proper bearing against the last when the latter is brought' thereagainst, all as will be more fully hereinafter described. The saddle thus sustains both the toe and the heel end of the last and the longitudinal movement ot the saddle on the slide 26 is that which brings the llast always `in the one invariable position above referred to, 'this position being determined by a positioning member. 1.05 against which the heel of the last is brought, by the sliding.,r movement of the saddle, all as will be more fiilly.lie reinafter described. This movement of the saddle toward the positioninlc` member is alsoutilized for jacking the last, and during the jackingof the last, the last pin is {irst swung forward toward the toe support thereby to measure or come to a bearing in the socket inthe last, and then by a further n'ioveinent to jack the last, as will be presently de- .ln order to thus jack the last by this movement o'l the saddle the last block has depending. therefrom an arm 76, see Fig. 2, forked at. its lower end to embrace a pivot block 77 on the upturned end of a horizontal actuating slide bar 7 9 which by its movement relative to the slide operates to give the required movement of the last pin 30. The movement ofthe actuator slide -7S) necessary to give the last pin 30 its movement first to measure the last socket and then to jack it is secured in the present ernbodiment by forming on the actuator slide 75l a horizontal rack 84, see Figs. 2 and 5, the teeth at the under side ofv which mesh with a pinion 83 fast on a short horizontal arbor 82tjournaled in the support 72. The arbor at its outer end carries frictionally the pinion 81 which in turn meshes with a stationary rack 8U on the slide 2G. Thus as the saddle is slid in 'ardly to carry the shoe into the linvariable position referred to, the pinion 8l will run on its rack 80, see Fig. 5, and rotate said arbor 82, and its inner pinion, 3, thereby to causo the inner rack, Sil,

to outriin the saddle and by its relative movement to said saddle, -cause the last block arm, 7 (i, 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 toc support, 2t), provided t'orits reception. rThismovement ot the last pin is only preliminary and necessary to cause it to measure or to be brought li ghtly in contact with the pin socket wall, the friction pin, 8l, sliding on its arbor after this preliminary contact is obtained so as 'not to firmly jack the shoe at this time.

This toe support, 2S), whichis mounted upon the front. end of said carriage or saddle y71.,

is arranged for movement toward and from thc last pin, 30, and vertically to accoiffiii-i'odale the various sizes of lasts. To idirs end, the toc rest is carried at the upper ends of a pair ot'l bell cranks, S9, (Figs. 2 and 4t) pivoted at 5)() to a vertical lug, 92, `on said carriage, 7l, their horizontal arms, 93, being elevated or depressed to swing rearwardly or forwardly the vertical arms of said bell crank, Si), thereby to adjustI the support for dittcrent lengths oiLl lasts and also, by t-he change in angularity of the arms, to effect f portions thereof. A support is therefore here provided for the fore part of the last at two points; eat the toe and in the bend at about the instep ot' the last. The support maybe niade continuous or not. as desired so long as these two points are supported. But the lines of lasts ot.' different sizes vary materially and a two point support that would tit one'last, might, be entirely unfitted for a larger or smaller last and furnish only a single point of support thereto; To obvlate eeeoe y 3 this, my invention coniprehends pivoting, or otherwise adjustably mounting the toe support, so that it may readily turn 'or move to iind a two point or continuous bearing on 5 any last presented t'o it. To this end, the toe support, 29, referred to, is hereinl made longer than usual and is provided with a removable member or cap,'102 (Figs. 3-4),

in order thatapad.,may be inserted that will f present a toe seating face suitably shaped to the curve of the toe of the particular type ofA last for -the time being operated uponfand engage the same at least 1n -the two points referred to. That this member may be removed and also adjusted longitudinally, the support or cap carrier, 29, is provided with ways, 103 (Fig. 4), in which a rib of the cap is slidably mounted, clamping screw, 104, retaining it in desired position.` To permit this pad, whatever it may be, always to find its two points of bearing on the particular shoe presented to it, the toe support, 29, is pivotally mounted on the vertical arms of :said bell cranks, whereby it is free to tip into any position necessary/to find its two `points or equalized bearing on the last rest,-

ing upon it. For holding said toe support, 29, in the position into which it moves'as the' last toe engages and is vfinally seated thereon, to prevent the last from tipping up when pressure is brought upon the heel end or any other portion of the last, said" support has a depending arm, 99,- (Figs. 2 and 4) the lower end of which is provided with a segmental rack, 100, which overliesand is normally out of engagement with 1an inclinedA tangential' rack, 101, secured to said car-rige lug, 92, between said bell cranks, 89. To permit of the two racks being brought 40 into locking engagement, the pad pivot, 95,

is held in two vertical slots, 94:, said y'pivot 95, audits toe support being normally held elevated in said slots by spring pressed friction and bearing members, 96 (Fig. 2),

slidably mounted in pockets, 97, at thesides of said bell crank arms, 89,' with lifting springs, 98, seated at the Ybottom 'of said pockets under it to lift said members, 96,- d and the pad.

5.0 I In positioning the last, the toe support first swings to adaptitselfto the last toe as the latter is swung down upon it, the "continued movement of the last toe, as in the final! jacking operation, depressing said support bodily and causing said racks to intern lock, thus holding th toe support rigidly in,

its adjusted position and preventing any displacement when the' shoe is moved into pressure contact with the mold or form 50 adjacent either end of said pad supporti For positioning the last on the jack to 1 bringa predetermined point thereomnamely,

the ball lineof the sole, to the one invariable -positidn referred to regardless ofthe size 63 .of the shoe', Ihave provideda positiondetermining member or element herein shown as a heel gage 105, which positioning device is sustained by the slide and is situated so that the counter of the lasted shoe may be brought thereagainst by movement of the saddle 71. Thisy heel gage is preferablyadjustable so that its position may be shifted accordingto the size of the last to be supported on the jack. ln'the present l instance, the heel gage, 105 (scef Figs. .2 and 75 i' 3) is a vertical pivoted lever having a curved horizontal arm, 106, at its upper end `,to embrace and center the counter of the shoe. This lever is fulcrumed at 107, intermediate the ends upon an upright, `108, at the rear end of said slide, 26, its lower end being pivotally connected to a horizontal link, 109, arranged on the right sideof said slide (see Fig. The outer end of this link is, in turn, pivotally connected t0 a 85 collar, 110 (Fig. 3) formed on or secured to a horizontal rod, 111, slidably mounted in'guides, 112', at the front end of said slide. On the inner side ofsaid rod, 111, ysee Fig. 3, this collar is provided with a horizontal rack, 113, (Figs. 2-4) in mesh with a pinion, 114, fast on the hub of a drum, 123, (Figs. 2-4) journaled/and constituting a guide for a central vertical spindle, 115, (Figs. 2A) in turn s lidably journaled at its lower end in a fore and aft horizontal cross plate, 116, supported at the lower ends of depending arms or hangers, 117 (Fig. 2) of said slide, 26, the hub of this drum projects through a bearing in the slide and is provided with an operating handle, 118, and a pointer,

" 119 the former retaining the drum in place and the latter' moving over a scale bearing numbers` from 1 to 8, or other index marks indicating the positions to which the pointer should be moved to place the heel gage in the required position for the different sizes of lasts. `In the drawings, the several shoe ysupporting and positioning members are shown as supporting a number 8 last. Foi-.110 locking the spindle, 11.5, in the desired scale position, according to the last used, the slide,

`26, is provided with a segmental rack, 120

(Fig. 3) and the handle 118, with a spring pressed latch member, 121, operable in grasping and pivoted on said handle, .the lower or inner latching end, 122, of which engages said rack and holds the handle and' spindle in adjusted position until elevated by grasping the handle to ychange the adj ustmcnt.

It is desirable that the toe support 29 shovd also be adjusted into positions corresponding tothe different sizes of lasts in order luat it may properly support a last.` of any size," and my present invention inf,` volves a construction whereby the,` adjust-ll ing .of the toe support is done simultaneouslyj 'with the adjusting ofthe heel gagef In the present embodiment. further this simuleI v taneous adjustment of the toesupport and 1 30 vto which the handle has been moved, bringheel gage can be eti'ected at any position ot' the saddle, that is, the movement of, the saddle on the slide toward and from the heel gage does not destroy the operative connections between. the heel gage, and toe. rest -whereby they may be simultaneously adjusted. 'To secure this end the drum 123 in the present embodiment, see Figs. 2 and 4, has a. pair of dian'ietrically opposite' inclined slots, .1.24, in its cylindrical sui-tace, in `which is slidably n lounted a horizontal cross head, 125, 2)- centered and cured on said spindle and adapted to elevate or depress the. same by its vertical movements. The ends of this cross head are provided with rollers or other studs, 126, running in vertical guiding slots, 12S, ot the hangers, 117, to prevent,rotations ot the cross `heads and they coi'npel its vertical movement by rotation ot the drum. then the handle is turned to a desired scale position, the drum is correspondingly rotated, and said'inclined slots by their action on. the cross head, 125, elevate or depress the saine and its spindle the requisite distance to adjust the vertical position ot the. tee .pad to correspond with the desired adjustment o't the heel gage, 106, 4tor the particular last that is to be used.y Upon rotation ot the drum the spindle slides freely"through its hub andalso through the bearing in the cross plate, 116. Its upper end ha.si/z'iwligehtlJV or block, 129, having horizontal grooves, 130, (Figs. 2 and 4) at its sides, to receive rollers, 131, carried by the front ends of the horizontal arm ot said bell cranks, 8S). As the spindle and its head are elevated or depressed, said grooves, 130, act' on said rollers, elevate and depress said horizontal arm, as hereinbet'ore stated, and swing the toe supporttoward or from the heel gage and pin, an amount proportionate to the variation in the size or length ot the last to be employed,

and so as to bring the toe rest into desired supporting position forsuch last, as already7 pointed out. .This movement ot' the handle, 118, simultaneously adjusts the horizontal location of the heel gage or socket, 1.06, andthe horizontal and vertical position of the toe pad for the last indicated by the index niark,

ing the ball line of said last to t-he invariable position herein required.

To firmly and final ly clamp or j ack the shoe upon its support as the carriage or saddle, 71, is slid rearwardly to bring the counter of the shoe against' the heel gage in the size position of the latter, or immediately following suoli movement, suitable jacking means are provided, in the present instance comprising a rack, 132 (F 7), formed on the outer end of the horizontal actuator slide, referred to as supporting the slide block, 77. This rack is adapted to be vmoved by a pawl, 133,

(Fig. 7) formed as 'a bell crank and p'ivoted atits elbow just below the inclined rack, 101,

on a crank pin, 134 (Figs. 6 and 7) of a horizontal shaft, 135, journaled at its ends in said saddle, 71, and having a crank handle or jacking lever, 136, at its right'end (Fig. 4),

to rotate it. The short depending arm, 137,

of this pawl lever (Fig. 7) normally bears against a stop pin, 13S, which holds its hori- '/.ontal arm ele 'ated out ot engagement with the rack,`l32. ln turning the operating handle or jacking lever, 136, inward, however, the crank pin, 134, is turned down and invfardly, causing the pawl, 133, (Fig. 7) to engage said rack, 132, and by further movement of the handle in the same direction, push said rack rearwardly and cause its vertical arm carrying the pivot block 77, with it and positively tipping the heel pin, 30, farther outward to depress the toe ofthe last, tirst to depress and lock the toe pad by engagement of its racks, and then to clamp the shoe upon said toe rest, and effectively jack .the same. During this operation the pinion, S3, and shaft, S2, are rotated, but the Ytrictiional engagement of said pinion with itsv strait permits it to slip and turn idly on said shaft as it travels over its operating rack, 80. Obviously, however, the frictional engagement of the pinion with its shaft lnay be varied as desired to cause the pinion to also turn idly at any other time .dn-ring the positioning Vofthe shoe,` tor example, immediately following the measuringY movement 6F the heel pin and the automatic seating contact of the shoe upon its toe support to permit the locking movement of its racks, the subsequent jacking movement, eti'ectually clamping the shoe thereon. yI prefer, how-. ever, to operate in the manner first described,

The mechanism is so arranged that iinmediately after the shoe is seated in its heel gage to bring the ball line to the position required it is firmly clamped upon its Support or jacked. It is however desi able, to prevent the jacking handle, 136, turning to ack the shoe until the .last pin has measured` and taken up all slack between yit and its heel pin socket, otherwise much if not all of the jacking movement of the pin might be lost and no jacking accomplished. To this end, said handle is prevented from turning when grasped by the operative' to slide the carriage rearwardly while the last pin and socket measurement is taking place by a stop lever, 13S) (Fig. 2) that depends from the left end ot the bell crank pin, 90. Intermediate its ends this lever has an inwardly projecting shoulder. 140, to engage a radial projection or shoulder, 141, formed on the left end of the crank shaft,`135. The lower end of this lever .is pivotally connectedwith a horizontal slide rod, 142, (Figs. 2 and 3) mounted` on said jack carrying slide, 26, and passes through a sleeve, 143, on a' flanged member,

eeaaoe 31 ladjusted position. In the' inward sliding inovement'ofvthe jack, this stop lever, 139, prevents any turning of the handle, 136, untilitle jacktravel has, 'through the friction 'pai'i'on and racks described, measured' theelast-pm in the socket, after which the nuts, 142, 'on saidslide rod, V142, (Fig. .2) strike the outerend of said sleeve, 143, and

' causesaid stop lever to he tripped from engagement with its locking shoulder on the crank shaft and permits the handle thereafter to turn and complete the jacking of the shoe after the latter is clamped into said heel socket or gage. v l 'i For' holding the jack in adjusted size po'sitionen its carrying slide, 26, suitable locking mechanism is also provided, in they present instance, comprising a two arm f`- pawl,

l146, (Figs. 2 and pivoted on an eccentric studor crank pin, 153of the. handle operated shaft, 135, said pawl engaging a ratchet or rack, 152, in the slide, 26, a coil spring, 149, connecting saidarms normally drawing them together. As herein shown, this pawl is provided with horizontal 'cross pins, 150, traveling in forked ends, 151, of

said arms and which actas guides and stops to respectively direct and limit their lon- `@fitudinal movements or relative sliding. The inner end of the pawl is provided with a depending tooth to engage said stationary rack, 152, on the slide, 26, permitting the carriage to slide rearwardly, but preventing its forward movement As the carriage is Y shoe thus yieldingly maiiitained against the.. ,positioning or heel gage nicmblei,`106. The

moved rearwardly to' cause the shoe to he seated against the heel gage clamp, 106, said pawl, 146;y engages said rack and locks the carriage in position, while lthe continued movement of the handle completes the jacking of the last or shoe, and simultaneously by the rotation of the handle operated shaft, 135 moves the pawl pin, 153, to its outer dead center position. By this movement of the pin, the hulohed arm of the paivl is soparated frotm the toothed ai'm in engagement Vwith the rack, 152, against the tension of Aits spring-so that the carriage is held under spring pressure in inner position with its pin, 153, being in or approximately at dead center position prevents the rotation of theA handle shait, 135, which might otherwise hel prodiieedhy said spring, and thus locks'the' handle in jacked position, thereby preventing the reve-rse or outer movement, of the actuator bai', 7S), and consequent uiij'a'cking ofthe shoe. Furthermore, the hearing sur# f faces of said shaft and its hearings produce" suliicient friction to prevent the spring'acting on said pin, 153, from rotating"said`- shaft in the normal jacking position of said pin, so that it is immaterial whether it 1s,v moved to its exact dead center or not. To govern the movement of this pawl, 146, they left end of said shaft, 135, has a pin or stop, v 154, A(Fig. 2) 'adapted to engage a'ra'dial 75' projection, 155, on the outer ory lug ed end l of said pawl and normally holding t e locking end of the pawl elevated out ofengagement. withv its rack. When, however, the

last or its shoe, the forward movement of said pin permits the pawl to fall upon thefr rack and to interlock therewith. To unjack the shoe this handle is grasped and `pulled j outward, thereby turning it in the opposite V direction and causing the elevation ofthe' carriage locking pawl and; unlocking the carriage permitting it to he moved forward.A Immediately preceding this '-'fhrward vmovei rying stud or crank pin, 134, is turned up` ward and forward, so` that the stop, 138,: trips the pawl, 133; and releases the slide har, 79. The forward movement of the'caij-Y i riage then operates to cause the pinion; 81,;95F to run forward on the rack, 80, tlurii'ing i`the} last pin, 30, toward the heel gage,elevatingv the last toe, permitting the last to he readily j removed and leaving said pin inclined reari thereto. Obviously-however, there `will he no chance in the ypositions of lthefnheel gage,` 105, and the belt/cranks, 89, until the sizey adjusting mechanism is again operatediiwlt will furthermore be understood that 'in re- 105 moving the last, the toel rest is released :toty
