EDWARD A. STIGGINS, or BEVERLY, MASSACHUSETTS, AssIGNoR To UNITED SHOE MACHINERY COMPANY, OF PATERSON,

JERSEY.

To all 'whom it may concern:

Be it. known that l, llmvann A. STIeGINs, a citizen ol" the United States, residing at Beverly, in thc county ot' Ilssex and Commonwealth of l\'lassaohusetts,` have invented certain Improvi-ments. in Jacks for Shoe.- Machines, ol which the. following description, in connection with ythe accompanying drawings, is a. specitication, like reference characters on the drawings i'ndicatinglike parts in the several figures This invcntiol'i relates to jacks for shoe machinesl and particularly `to jacks for use in connection with lastinp` machines.

The invention is shown as embodied in a' jack oli the typo in which the last within the shoe is fitted upon aV movable last-pin and during the lasting operation is force-drear-` wardly into a heelibandwhich is thereby caused to embrace and clamp against the -last thc'heel portion of the upper materials including the heel stilfenerto conform these portions of the shoe to the. side faces of the last .and coipcrate with vother lasting instrumcntalitics,.as; for example thaty shown in my earlier applicationSerial No. 127,116, in conformingT the shoe stock to the bottom face and the edile of the last at theheelof the shoe, incliulinp)Y the upper.material'andV the counterc l Inthe preferred construction of jack herein shown a, pivotally sustained last-pin is employed and the movement of the shoe into the heel-band is efeoted by means engaging -the forepart ol the lastto rock the toe en d of the shoe.' Lu'nvardly and rearwardly In this movement of the shoe into the heelband the angular relation. of the shoe bottom to the edge of the heel-band is altered and as it is a matter of importance in the subsequent 'lasting operation that the edge" of the heel-'band shall. occupy a position Hush or parallclavith theI bottom of the shoe all the way around the counter, I 'have provided means for a'ngularly*moving the heelband..;As herein shown, the 'heel-band'is pivotally ,supported near its front Vendsv and at itsmiddle rear portionis connected to a movable support by means of which it`may be actuated `in the dircction'of the height of the shoe. to change the'plane in which its upper edge lies. 'llh'ej html-bandwhich I prefer to. employ yis flexible or resilient andl is normally-.held open with ends s pread impartiv wlde enough to receive readily the JACK FORl SHOE-MACHINES. l

further feature of my invention consists in an improved toe-band and in novel means for adjusting and actuating the tocband.

Other features of the invention, including certain details of construction and combinations of parts, will bc hereinafter described and pointed out. in the claims.

Figure 1 is aside elevation of a jack embodying the present. invention, the parts being shown by full lines ii the position which they occupy before being actuated to jack the shoe, while the dotted lines show the relative ositions of the toe-band, shoe bottom, an heel-band when the shoe has been jacked. Fig. 2 is a front elevation of the jack', certain parts being shown in section on the line 2--2 of Fig. 1. Fig. is a rear elevationof the jack.

The jack conipi'ises a base plate 1 upon which lis guided the carriage 2 for supporting the toe-band 6 and the carriage 8 for sustaining the lastfpin 10 a d the heel or counter-enibraoin -band 12. he carriages are preferably a justable toward and from each other for'shortenin r or lenrthening the jack by a rightand le t-threadied screw 14 which is secured against longitudinal niovenient in the base plate and is provided with an operating crank 16. The heel carriage 8 has ears 18, shown in dotted lines in Fig. 1, between'which is pivoted a support 20 for the last-pin 10. A spring plunger .24 is mounted in the support at the rear side of the pivot and rests on the carriage for hold-4 ing the support and last-pin normally tipped away from the heel band to enable the hist to be readily placed on 4the last-pin. The carriage S is roviided on either side with ears 34 to whici are pivotally connected the op' posi'te'ends of a casting 37. Curved spring '4.5 arrns40 are rily secured to the cast-ing 37 and are ivot. y connected at their upper ends to tlie end portions of the heelband.

The sprln arms are preferably formed so that they ho d the end portions of the heelband'norm'ally spread apart far enough to receive readily the widest last for which the jack is adapted. When pressure is brought le rear portion of the:A heel-band -1 the arms yield inwardly .to

raoe sind cla-mp the upper materials against the last.v The middle-rear rtion ofthe band is connected by means-o an 'adjustable upport 42 with u lover 44 -w'hich is shown as crume at AMito one of the spring arms 40.` Bv actuating the -leyer 44 the band may bero'clted .in-'the direction of the height of the shoe 'about its pivotal connection withV reciting; the shoe backwiirdly into thel heeiin this movement. the cxtremv rear end of the heel of the shoe is obviously lowered.

The heel-band nia)1 be operated by means of the lever H- lo maintain its upper edge pai*- allel with (he bottom of the shoe during this rocking movement. It is found in practice that as the shoe is rocked bacltivaidly the portions of the last adjacent to the front ends of thc counter rise slightly, and if the cud portions of the heel-band have not a corresponding movement there is a tendency to draw the upper at this point downwardly away from the last bottom. To overcome this tendency and permit of the heel-band beiner moved in such manner that its upper edge may be maintained at all times flush or parallel with the bot-tom of the last I preterably locate the pivotal connection between the end portions of the band and the spring' supporting arms 40 ata short distance back from the ends ofV the band7 whereby when the band is rocked about said pivotal con-- neet-ions the front ends of the band rise enough to compensate for the sli rhtrise of thelast at the adjacent portion o the shoe. The casting' 37 upon which the sprinU-aifms 40 are carried, is arranged toy be move( manually about its pivotal connection with the ears 34 for the purpose of adjusting the heelband toward and from the last-pin, and a spring paw] 36 engaging a ratchet 39 holds the casting in adjusted position. Means is preferably provided for depressing the shoe, whatever its height7 into aV position in which its bottom face is flush with the uper edge of the heel-band. The shoe depressing means comprises a yoke 41 having a contact piece 43 for engagin j the bottom ofthe last. The yoke is pivotal y connected to the operating handle 45` which when tui-ned from the dotted line position in Fig. 1 to the full line position in said figure will draw the yoke downwardly and cause-'the shoe and last-pin to lie-depressed into the position shown in full lines in Fig. 1.

Fir'i The upright carriage 2.at the' front end l Aa longitudinally movable. postl 50 .to which is pivotally connected :ijcairier 52. To the downwardlj7 curved rear end of the'ca'ri'ier 52 is attached a socket piece 54 having n screw-threaded guideway for receivingan ad]ust able stop screw 56 -upon the upper lend of which rests the stem` 58' of the toe-.rest 00.

The socket pie has n one side a slo't which forms a guidewayfor a laterally projecting pin 69whicli limits the movement, of the stein 54 in the socket piece and prevents rotation of the toe-rest. The toe-band is supi ported b v a holder comprising a. block-G4 connected by a pivot in 68 tl the frontend Aof the carrier 52 an provided at its lower toe-band is connected to the blockA (34 by Y links 75. The pivotal connection between the arms 7U and the block (i1L permits the toe-band to swing from side to side to adapt its position to theposition and shape of the toe ends of'ditt'erent lasts. 'lhe rear ends of the levers are connected by a right and left threaded adjusting screw T?) by which said bars together with 'the spring arms 'T2 upon u l the op osite sides of the jack may be moved towar( ol' from each other for spreadlng or contracting the toe-band according to the width of the shoes to 'be jacked. The post 50 is provided with rack teeth 74 engaged by a pimonfti carried by a shaft 78 which is journaled in a bearing extending from the carriage Q. An operatinv handle 80' is cured to the outer end of the shaft 78 and `by depressing the handle- 'the post 50,.to getlier with the toe-rest G() and toe-band 6,

may be raised for rocking the shoe rearwardly into the heel-band and wiping the upper on the toe portion of the last toward the lastl bottom. The lever carries a pawl 82 adapted to engage with ratchet teeth formed pn' a circular plate 84 attached to the outer end of the shaft bearing for lock-ing the handle in vadjusted position. A spring` 8G connects the carrier with the carriage 2 and tends to return the carrier and'the parte.supported by it to their lowest position when` the pawl 82 is disengaged from the ratchet 84.

Preferably and as herein shown, means is provided for adjusting the toe-band angiey arly in a direction transverse of the last to adapt the toe-band for use with twisted lasts; in which the last' bottom at one edge is higher than at the other edge. 'To this end the block 64 is formed with a bearing for a short shaft having' on its rear. end an eccentric 92 located in a slot formed 1n the' carrier 'lhe shaft 90 is provlded onk its outer end with a hand wheel 94 the shank of which has a ronghened surface 95 engaged b v a .spring pa wl 91' for holding thc eccentric in adjusted position. By turning the eccentric in one direction or the other the block (i4 may be moved angiilarly'about its ivotal connection Gti with the carrier 52 an thereby singularly adjust the toe-band in the direction of the width of the last. AIn this adjustment of the block (34 the opposite. sides of the toe band are simultaneously moved vertically in opposite directions` by means of the connections 72 and 75 between said blockand the band. i y

Itis desirable to move the heel-band about its pivotal connection with its supports 40 at the same time that the toe-rest and toe-band into the heel-band, as by so doing the heelband may be maintained continuously with its upper edge hush or parallel with the bot; tom of the last. y '-lo this end 1 have herein shown `a colinection between the post 50', by means ot' which t'liejtoe-rest kand toe-bano are elevated, andthe lever 4.4,jby means of which the heel-band is rocked. This concured to the post 5t) and arranged to slide freely through an elongated guidcway in the front end of the lever 44, whereby the connection between the post and the lever is maintained in Athe various yadjustments of the jack for longr and short shoes. The heelband might of course be arranged to be rocked independently .ot' thel operationotl the toe-band` it' so zdesired. sitionotfthe heelfband may be varied by ada turn buckle. l .y

In using the jack thecarriages and l jacked, and if the last is a twisted last, the toe-band is adjusted angularly'by means ot the hand wheel 94 The-shoe is applied to Athe jack by titting the heel end of the last onto the last-pin l() and resting the forepart of the shoe upon the toe-band,as shown in Fig. 1.. The shoe depressing means is then moved into engagement with the bottoni ot )ressed from the `dottedhline pfosition yshown said` ligure for forcing' theishoerdownwardly until the bottonrof.the shoe is flushi'vitli the upper edge ofiwthe heelfband,the*y spring- Sustained last-pin yienting to permit this movenicnt of the shoe. The handle 8() is then` depressed for raising ythe toe-rest (it) and toeband and in this movement the toe-band is raised along the sides and end of the shoe, wiping the upper materials toward the shoe bottom until it reaches a position in which its upper edge is [lush with the bottom of the last. and the band embraces the entiredoe portion'o'f t'lie,.shoe for holding' the: upper in .the` position to which it has been wiped. y `Alsoby this same n'iovement the sho1 rocked about the pivotal connection ot'fthe last-pin .1()` with the the heel-band and "inits'i'urtlier rearward movement the spring arms 4() yield inwardly and cause the front ends of the heel-band to embrace the sides of the heel portion of the shoe. The ,rocking movement ot the shoe obviously causes the extreme rear end of the shoe`to move downwardly, but the connection between the postl5()` and the lever 44 causes the heel-band tov be rocked inthe dinection is shown as comprising a .bar 9S se! The initial po?y justing the support/42, whichjto this end, is l l shown as made mtwo sectloiisc'onnected by n are adjusted for the length; of shoe to .bei

revtion of the height of the shoe, whereby the upper edge of the heel-band is mainbacluvardly into t tained flush or parallel with the bottom of the shoe. The pawl 82 locks the handle 80 and therefore the several parts inthe osition to which they have been moved an the shoe depressing means 'may then be released and moved into in inoperative position, leaving the shoe ready to be presented to the lasting machine or'to any other mechanism by which the shoe is to be acted upon.
