Specification of Letters Patent.

Patented Noir. 2, 1909.

Application filed November 6, 1907. Serial No. 401,015.

siding at-5Essex, in the county of Essex and Province of Ontario, Dominion of Canada, have invented certain neW and useful Improvements in Lasting-Machines, of which the following is a specification, reference being had therein to the accomPanying drammgs.

This invention relates to improvements in lasting machines of that class in which wipers are employed to last the heels and toes of boots and shoes, and more particularly to improvements in theconstrnction shown in my United States Lettexs Patent, dated March 17, 1908, No. 882,018.

One of the objects of this invention is to so construct the machine that when a last is placed therein having a boot or shoe in place thereon for lasting, the wipers and last Will automatically adjust themselves to conform to any Orclinary irregulztrity or change in the form or size of the shoes being lasted, thus avoiding the necessity for careful and accurate placing of the shoe by the opcrator, and further to provide a construction which Wlll permit the operator to place the lastin position withouthindrance and give an unobstincted view of the work.

tis also an object of the invention to providc means O1 engaging the edge of the shoe uppcr and clamping the same against the edges of the wipers which means is adapted to yiql lingly open and close in conformity with the variable 1novcment of the wipers so that the loather Will be firmly held all along its edgewegardless of the size of t'orm of the heel or toc et the. shoc.

A further objcct of th-is invention is to provide means for autonmtically stretchlng and securinga wire around the toe 05 the last to hold a shoe upper in place thereon after the lasting. operation, and to so constrnct the machine that the pressure of the wipers Will be relieved at the end of the lasting operation to permit the wire to be drawn closel v around the lasted edge. And it is also an object of this invention to provide certain other ncw and useiul features in'the construction. arrangement and combination .of parts, al] as hcreinafter more'.fully doscribed, reference being had to the accompany1ng draw1ngs in Wh1 Ch:

Like n-merals refer to like the figures.

As Shown in the drawings, 1 is a suitable pedestal having a head formed with a top or table 2 which is inclined from the homparts in all of zontal so that when standing in front ofthe machine, the operator Will have a better view of the machine and of his work. Sev cured upon this table at its rear edge, are

bearing brackets 3 each forined with two bearings, one for a driiring shaft 4 and the other for a conntershaft 5.. Motion is transmitted from the driving to the driven shaft hy means of a pinion 6 on the driving shaft 111 mesh With a gear 7 on the countershaft Which pinion and gear are in the proportion 'of three to one so that one revoltion of the gaged-by a dog 11to stop the shaft at the end of each revolution, said dog being released by a rod l2attached t0 a foot lever adapted to be moved by the operator.

Secnred upon. the counterslmfc is a cam wheel 13 having an internal carn groove 14 engaged by a roller 15 on the tail end of a rocker-bar 16 Which is pivoted intermediate its ends npon brackets 17 sebured npon tlic forward edge of the table 2. This rockerbar is fornied With a guide way for a sliding pushbr 18 (vhich is moved longitudinally therein by a roll 19 on its rear end engaging a. cam grov 20 in a cznn wheel 21 secured on the conntenslxait. A. pont 22 is secured to the forward end et the pnsh bar and pivotally attached to the lmver.end 0]. said post at their point of intersection are the crosed levers ,the forxvard ends 0l' whieh are slotted imvard to receive the vviper plates These plaies are detaclmlfly and pivotally secured xvithin their ,slols b v pins: 25 passing through holes in the levers, and throngh elongated openings 26 in the pintes, said openings extending snbstanially in a direction longitndinally of Ll1elevers, 'lhese wlper plates are hinge co1n1ec'ted and previded with adjacent :lior;ned odges 10 cm:- ior1n to the shape of tl1e heel or toc (il? tlm shoe being lasted,and when said heel or tee isbronght into contact with said edges, tl1e Wiprs are free to shift laterally on choir levers to conforrn io the shape of the heel or me and bring the center line of the forming notch in the'wipers inlo concidence wvith the longitudinal renter line otl said heel or tee. Tl1e wiper plates are tnrned relalively on their conneeting pivot to open and close theforming notch or jawe ol the vcipers; the push bar 18 isprojected or retracted and the post moved, by eormecting the rearwardly extending ends et 1.110 erosscd levers by a plate 2'7which is securod to -tl1e f0rWard end of a bar 28 exte1iding rean lower side of the rockeflbar 16. Said plate 27 1s prov1ded W1th forwardly converging slots 30 lhrongh wlnch the p1ns or bolts 31 .cminecting the levers. to the plate, pass and.

allmv the'plate 27 vro move forward With the levers. A ;secoi1 d'collar 34" on the bar in front of-theforward bearing ar, limits tlne .rearwa1d m0enient of the bar and flismade 'admstable theredn t0 set;the ,wipers relative -to the heel o1flioe.0f th shoe so that they will be "projeted a greater or leseer distance over the saine irrthelasting operation. The push bar W1th 1ts pOst and p1votally attaehed wvipers, and the bar 28 are all car ried by and rock wi.th-the rocker bar as is 'also a pnsh-fod 35 which slides in a guidevvay provided therefor in the rocker-bar at one side of and parallelwith the push-bar. On the rear. end of this push-bar is a roll 36 engaging an ontside Gain surface or track 3? on the ean1 Wl1eel 21 and its f0rward end' is extended l;iterally to engagea clampirig arm 38 which .is pivoted at its upper end t0 the upper end of the.post 22. A spring 39 exerts a force t0 sW1ng the arr n downward and said arm 1s made in two parts, the lower part or orenrm 40 being pivoted to the np per part and provided with a shonlder: 41"

adjacent to its pivot t0 engage a projeeting portion or stop on he npper member and lini it its downward turning movement rela tive to said rne1 nbtr. A sp1*ing 42 is provided to tnrn said forearm into engagement witli its stop when the arm is raised by the push-rod Which engagea the npper inember of the ar1n only.

livotally attachcd to the lower end of the dumping arm are two' clamping fingers 43 which are cnrved t0 conforn1 snbstantially to lhe -cnrved contact edges of the wipers and are i.'onnded on their lowcr eide to rest npon tl1e inelined portion of said edgcs with th npwardly projecting edge of the leatler of the upper to me lasted, clamped between. The pivot onde of the clamping fingers are let into the lower end of the dumping arm' Which end is ronnded off so that it, together with said fingers,' forme a continuons sn1ooth ronnded surface to engage the inner side of the leatl1er. ;These lingers are .tnrned on their pivots toward and fro1nach other as the wipers are opened or closed, by4levers 4:4: pivotally attached at their forward ends to said fingers and curvedrearwardly around the clamping ar1n where they are CrosSed and pivoted together at- 45. To the rearwardly extending'ends of each of said levers is attached a light coiled spr ing 46 t0 pull reai*wardly on said ends and normally hold tzhe fingers .closed or turned toward each other, and secured to the forw ard side of the post 22 is a.flat transve'rSely extending Spring 47 whieh is adapted to.be engaged by acljnst able Stop screwsd8 carried by the rear ends of said levers 4.4: when the clamping arm is lmvered t0 clamp tl1e shoe npper. \Vhen the clamping ar1n is turned upward on its pivot by thepnsh-rod 8:3, its forearm is turned 1elative to it by the spring 42 with the clamping fingers extending in a plane substantially parallel to the plane of the Wipers, and

' for1ned edges of the wipers', at th same time spread1ng sa1d edge bythe open1ng out'of the fingers and thns taking ont ail of the vvrinkles. By providing the joint in the cia1nping arm, the fingeis are iowered in position to engage tire npstanding edge of the leather e=:ent;; throaghont their iength, the for ard ends ot said' fingers being as 10W or ioxver than the end of the ar1n when the same engage the work, and When the pnsh-rod fntly retracted the spring 39 partiaity over- -omes the spring 42 and the arm straightcns out. The fingera are. vieidingly tnrned ont- \vard into eont:n:t With the work b v the spring 47, the active pressure ot xvhieh may be easily regnlated by the stop-sawmvs 18 and the clainping arm is yietdingly held against the work by its spring 351 so that any variation in the shape or size of the ]ast or the thielcness of the teather is anto1hatieaily provided for.

Iivoted intermedizate its ends Upon one of the bea'ring l raekets 17, is a rocker-bar 49 having a roll 50 on it:s rear end to engage the outside (rani face 51 of a cam wheel se cnred npon the conntershaft a spring 53 being provided to hoid the bar With its roll in"contac nith the cam, and a transverse opening in the forward end of said bar forms a bearing sent for a rack bar the ]mver end of which is provided vrith teeth t0 engage the insoie of the. shoe being lasted and formsa presser-foot to hoid the last in place. A \vorm is jonrnaicd in a stot in the end of the presser-bar 49 in engagement with the teeth of the rack so that by turning said W01111 the presser foot is adjnsted np or down, and pivotally attached to the foot near its lower end is a presser-mm 56 extending rcarwardly tl1erefr nn and for1ned With teeih t0 engage the shoe sole near he point of the toe or end of the heel. 4\ tait piece 57 on the presser arn1 extendsfomvardly and up' wardiy from its pivot and a tinm'ib-screw 58 engages a screvv-threaded opening in the foot and is pivotatiy attached to the tait pince so that b tnrning said thumb-serew in or ont the presser-man is rocked on its pivot and the position of is contact end relative to the foot is adjusted.

In Fig. 1. is shmvn a presser bar 94 which is cnrved dmvmvard interme ttiate its ends to bring its pivot. snbstanti:diy in alinement with the wiperz so that When said bar roeks dmvnward at its forward end, the presser foot \\1i1 no! t e carried imvard toward the wipers and tend to zn gvo the tast.

', To hotd the insote down at the extre1ne point of the toe s-:o that it xvill not be wiped np or tnrned backby the operationot ti!e wipers, a toc piece 59 is provided eonsistin of a rearwardly cnrved bar tiattened at its lower end to engage the work and adjnstably secnrcd by'a set screw (30 at its npper end-in a yoke 61 pivotaily attached to the presserbar 49 in such a'position that said toc pieee' wll engage near its lower end, the lower end of the clamping arm between the forwardiy extending ends of the cIamping fingers, sa1d toe piece being thus yieldingly 'held in conpierre is in position t0 engage the sole at the proper point and at the proper time, the esser-bar holding Said toepiece in contact with the sole while the wipers are raised and iowered in the lasting oneration and the ciamping arm forcing said toe-piece out of the way as the wipers are projected f0l'- wardly and downwardly upon the work tm, Jay the edge of the upper down upon the sole.

To hold the last npon which the shoe to be iasted is secared, and clamp the same' firmly in position for lastingp against the ends of the presser-foot and presserarm, a jack is provided consisting of a post 63 monnted in bearing cars (34 and 65- on the forward end ni a rocker-bar 66 pivoted intermediate its ends between the bearing braekets 17 and having a roll 67 on its rear end to engage an ontside ean1 surface 08 on the cam wheel 13.

On the npper end of the post 63 is a head (3!) shaped to conform to the surface of the last nst forward of the instep and form a support for said last at a point intrmediate the points at which the presser-foot and arm engage the sole. Said head is formed With a socket to receive the'npper round end of the post whieh is provided With a groove 7O to reeeive the end of a set screw 71 in the 11 sud and thns hold the head' in place and permit of a tree tnrning movement on the post so that when the iast is placed thereon and bronght into contact With the wipers, the sont xviil tnrn and adjnst the last to the wipers, thns providing for the use of rigbts and tet'ts and also lasts of varions shapes and. swings. 'j'he foot is yieldingly snpport od in its hearing cars by a eoiiod spring 72 sleeved thereon between the lower car and an adjustable coiiar T3.

'Ehca edge of the shoe npper is heid in ptaoc after the lasting operation by a wire stret(-Iied tightiy around the toe npnn the laid over and tormed down portion of the upper adjacent to its edge, and made t'ast at its cnds to tacks driven into the sole at eacii side seine distance from the point of the toe. 'lo antonmtically draw this wire to place and partia]iy secnre the same to hoid the. tensio1ttvhile the last is being removed froni the machine, a snpportting bracket 74 is seenred to one of the bearing b adrets 17 or other 'st'atioi'iary part of the machine, and pivot ail nttached to the forward end of said braeket is a s\vinging ai'm 75 provided with a revoinbte head 76 at its lower end having' a tztrrsverse ho]e througlrwhich'thewire i;

threaded.v A joihtedrod.77 is pivotally attached tO-said swinging arm at one end and at its opposite end to the upper end of the post-22 o that When the .push bar 18 is -movd f0rward. motion Will be transmitted therefrom to swing said arm, the position of which is such that its lower end-carrying the 'wire WilL move from a point at one side of and some distance from the toc of the last to a point over and adjacent to the uppensurface of the sole, forwardly of the tack to whichthe wire is to' be secured after the lasting operationfi 'To guide the wire to place close up beneath the wipeis at the Point of the toe, a sprin'g ami 78 is secred at one end to the upper side f,the jack-bar'66 with its ree endengaging the underside of the wipers, and on this free ncl of the arm is a -turned down Portion which forma an abutment or stop 79 agaihst Whichthe toe of the last is placed in putting the Saine in position for lasting; A curved guidearm 80 is also provided to guide. the wi're up over the edge o f the sole and over the securing tack as the -wire is drawn forward by the swinging arm. T This guide-arma is pivotally attached at oneend to ,the lower end of the post 22 and curves laterally outwaid atone side of the shoe and upwardwith its free end normally lying directly over and close to the tack to which the wire is to be secured. A spring 81 yieldingly holds said arm turnedto the posi tion described and permits of its being tnrned backward if in theway in inserting the shoe. W'hen the swinging arm is moved forward to stretch the Wire around the toc, said wire engages and slides up the inclinecl end'of the guide-arm80and drops;oi the end of Said arm behind the securing tack so that when the arm swings backward, the

wire is 100ped around the tack to hold the Wire while the last isbeiiig removed from the machine.

' The wire is supplied from a spool or other device, not shown, and to put a friction on the wire so that when the arm 7 5 swings forward the wire W111 be drawn t1ghtly. around the toe of theshoe, a tension device 89 is provided, consisting of a post 88 secnred tu the machine table adjacentto the jack-bar 66 midway between its pivot and its' rear end, and on the post is sleeved a coiled spring 84 andawasher 85, and also a thimble 86 havinganj arm 87 secured to the jack ba1 when the,frictional contact of the thimbl with the wire Will be relieved, permitting the wire to be drawn through freely the operator.

Near the endof the lasting opeiat1on, the

edge of the upper and sole, so that it is yery hard to draw the securing wire beneath the1r ygvipers are pressing down hard upon the edges into contact With the formed edge of the leather to hold the same securely, and therefore it is desirable to reliexze the pressure slightly just before the swlnging 'arm finishes its f0rward movement to allow the '.wire to be drawn beneath the edge of the aim. As shown at 88 in Fig. 12, the am foroperating the jack is reduced in size at ayipers by the.forward movement of said this point so that'the jack Will belowered slightly and as the sprihg 7 2 of the jack is compressed by the upward movement of the jack in cinmping'thelast, this spring, by expanding, wou.ld maintain the pressurebetwen the last and wipers if it were not for a dog 89 which is piVoted upon the bearing.

65 and adapted' to engage a series of notches 90 in the post 63 so*that as said post is forced downwa'rd in its bearings againSt the action of said spring, it is lockd against up ward movemeht by the dog; and thus.moves with .the jackbar. -To relese the .dog, a forwardly extending aam 91- is rigidlySecured to the table or other corivenient. stationary part of the machine, and so posi' tioned that When the jack is'loWered releasing the last, a tail on the dog Will engage said aim -just before the jack reache- 1ts lower position and throw the dog engagement with thenotches.

' Ordinarily the shoe upper is secured to the out of last by tacks. driven through the edge ofthe leather and sole into the last, and usually a tack is placed at the point of the toe. 'Be-- fore the toe can be lasted,it is' necessirytd remove this tack and for this purpose a} puller 92 is secured in a horizontal pos tion to any convenient stationary part of the frame, and consists of a plate provided with a series of taperingslots extending inward from one end of the plate and forrhinga series of fingers 93 between, this end of the plate being beveld atits lower side and straight on its 11pper side to form sharp fiat ends on the fingers and said slots are ex-f tended farther inward at the -upper side of the plate than at the lower side. By-taking hold of the last near its -heel, the pointed ends of the fingers may be shoved beneath the head of the tack and a downward movement of the heel end: of the last Will then e'asily pull the tack, and the oper ator Will have the last in his hand in position -to be placed in the machine.

In Figs. 7 and 8 the se veral zictuating cams are diagrzimmaticzilly illustrated show in,q thir relation to each other when the rolls cngagmg'said cams are in the positions indicated by the dotted limes marked a, I)

- at rest with the jack clown, the roll 67 bein,c

in contact with the small part of the jack cam 68; the wipers are in their lowered position, the roll 15 on the rocker-bar being in contact 'lil] the. concentric inner' part of its cana; the pnsh-bar caiwying the wipers is in its rearmost position, the roll 1.) being in the innermost part toi its cam groovc; the

push-rod 35 is projected t'orward by its cam raising the clamping arm 38; and the roll 50 on the end et the presser-bar is in contact With a cubaway portion of its carn so that the presser-foot and presser-arm are raised. The parts are thns opened np to give free access in putting the shoe in place with its me 11 agi1inSt the stop on the spring arm 78 and the edge of the upper projecting npw'ard adjacent to the forming edge of the w1pers.

VVhen the operator starts the machine by actuatmg the dog 11 to relettse the ivheel 10 and permit the clutch to operate, the presser bar is first rocked,*lowering the presser-foot and arm into contact with the shoe sole and also bringing the end et the tocpiece into engagement with. the sole at the end of the toe adjacent to the npstanding cdge of the upper.. The jack is then raised by its cana, clamping the last firmly bctween it and the presser foot and arm and a inrther tnrning of the cam-shaft, l rings its small side of the cam 37 opposite the roll 36 on the pnsh rod and permits the clamping arm 38 to be swung downward by its spri-ng, hringing the elamping fin gers in contact with the npstanding edge of the upper and clamping the same firmly against the edge of the Wipers. The parts have assn1ned this position dnring one turn of the power shaft andare stopped hy the dog 11 in the position shown in Fins. 4 and 5 and with the ca1n rolls in position 7).

\Vhile the machine is at rest in position 7), the operator thleads the secnring wire across over the spring arn1 78 and 1nakes its end fast to a tack driven into the shoe sole. The machine is then again started and dur ing this rotation of the power shaft and the turning of the cams front position 71 to c,

the wipers are rocked to their nppernxost position and then lowered to their lon'est position, at the. sain-e time being gradnally moved jorward by the pnsh-bar to the limit of its stroke. The npward and torward mmernent wipes and stretches the leather hghtly over the last and the downward and forward movement tolds the. edge of the leather over the last and presses 1t down hard, the forward n1ovement, cansmg the ing the wipers to the levers and wiprs at the same time to close inward, Daring this movement of the wipers the jack is raised slightly by its am and the presser foot and arm are t'orced clownward a short distance, so that when the heavy clownward pressure of the wipers comes on the last, it Will be secnrely held relative thereto aaainst an possibility of movement. The jack roll (37 just as it reaches position 0 drops to a rednced portion 88 of the ca1n, thus reducing the pressure of the jack agz1instthe wiper to permit the secnring wire to be, drawn to place, as previonsly described;

The stopping of the machine in position 0 is not necessary as the secnring wire is fastened to its tack to hold the lasted upper in place, by being looped over said tack, as described, and during the tnrning of the cams from position 0 t0 a the parts are returned to the positions shown in. Figs. 2 and 3, or open position, thns releasing the lasted Shoe. The cycle of operation is tlms completed and the parts are in position to receive another last.
