Lawrence, in the county of Essex and Commonwealth of Massachusetts, have invented certain Improvements in Methods of Assembling Parts of Boots and Shoes, of which the following description, in connection with the accompanying drawings, is a spec fication, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to methods of assembling parts of boots and shoes.

It is a common practice to prepare the parts of a boot or shoe for the pulling-o er and lasting operations by bringing them to gether and securing them at the heel. 'l a present invention contemplates a no :1 procedure for performing this asseml'iiiug operation in an ellicient manner. The pwmedurc is preferably carried out by the aid of mechanism such as is hereinafter des ribed, but it will be understood that it may be practised with the aid of other nicchansiu and that the several steps hcicinatte-r mew ti oncd may, if desired, be performed by hand.

As is WQll-lx'llOWlL, the parts; brought together in the assembling" omration commonly comprise a lined upper. 'a counter and an innoi'solo. In assembling the parts the counter is inserted beneath thelining of the upper at the heel, the last is placed within the upper and the inncrsole is placed upon the bottom of the last, and the upper and counter then secured to the innersole by a tack driven through the upper, the counter and the iuncrsole at the extreme rear of the heel. It is particularly importantin the assembling operation that the counter be brought into close relation to the end edge of the inncrsolc before the parts are secured together. An improperposition ot' the assembled counter is ordinarily not remedied during the following openuions, so that a shoe which has been thus improperly assembled is impaired in value. An important feature of the procedure hereinafter described accordingly consists in press ing the counter not only down upon the face of the innersolc, preferably sustained upon ing the endsof the counter a last, out 2: againstthe rear e olthe inucrsole and the rear face of the last he: tore securing it to said mnersole. In press:

ing the counter againstthe rear face of ther lastor down upon the face i re inner-sole, there is ordinarily a tendez" spread the ends of the counter and ac them llO'Wn below the side edgesof the the cone of the last. objectionable more p articx imposes upon the laster the displacement is .lariy in that it "cs-sity of raisinto position above the innersolc before lasting. According to the pr int procedure, thev ends of the counter are held from downward m ir'vc mcnt past the side edges of the innersolc. while the counter is mine: pressed. in proper relation to the inucisx .e and occur: thereto.

in the manufacture of some kinds oishocs, partimlarly in the better 5., known as welt shuns. it is desirable to secure the parts of t shoe to the rear face of the last. in important bject 3 th i (-l'SiI-lfifl :21 i vi-nit later l i'li lf of thescani at the pullmo-mcz' is inserted after he mttoni ot the last. and hetero ;t the rear edge of the inncrsolc. After said fastening has been inserted, the upper strained over the rear edge of the innci'solc and scmufcd to the iuncrsolc. The upper between the two fasteuings is thus bi'tuight closely against the rear face or" the last.

()tbei' f aturcs oi the invention fwili he dodwvn upon it is pressed a1:

scribed in the following" descriptixhi. i

In the drmvings, which illustrate a ma chine by the aid of which the pc'nt method may be conveniently practisv Figure l is a. view in side elevation at the more important parts of the machin Fr 2 1s a View in horizontal se tion on tac line w-;. of Fig. 1; Fig. 3 a view in vertical section showing parts of the machine im' medial'ely adjacent to the last operated upon; Fig. 4 shows a shoe after being assembled, and Fig. 5 shows a shoe provided with a straight counter before the completion of the assembling operation.

Referring to the drawings, the reference 5 numeral 3 indicates a suitably journaled shaft arranged to be given one complete rotation at the will of the operator by the actuation of a treadle rod 15. Below the shaft 3 the frame of the machine is provided with a horizontal table 21 in Which. is formed a groove adapted to receive a stem 22, the ior- Ward end of said stem constituting a rest 24L- arranged to be ged the heel. end of a shoe. A. stop 26 is mounted upon. the frame in advance of the rest in position to bear on the sole of the shoe, the lower face of said stop being corrugated and the stop being arranged for vertical adjustment. A horizontal guideway 28 is formed upon the frame below the rest 24 and the stop 26,:1nd a post 30 is mounted to slide upon this guidew ay. A vertically adjustable sleeve is arranged Within the post 30, said sleeve supporting a rod 36 constituting a last supporter. The adjustment permitted the sleeve 32 allows the position of the upper end of the last supporter to be varied to accommodate different heights of lasts. The last supporter 36 is engaged by a lever 42 which is forced up- W'ardly by an adjustable coiled spring 4%, "the last supporter bein thus yieldingly sus tained to provide for slight variations in height of the last. The pressure with which the innersole is clamped upon the last is controlled by the spring 46. A rod 54 is ar ranged to be actuated by acam upon the shaft 3, this rod hearing at its lower end yieldingly upon the lever 42.: The rod 5 is normally in a depressed position in which 1 the lever 4:2 is held down, and when the rod 54 is automatically raised spring #3 raises the last supporter pressing sole Y the against the stop The ertical adjustment permitted the 26 allows the height at which the last is i id to be varied. Two levers 74 are pivoted upon the table 21 at'opposite sides of the stem 22. The forward. ends of the levers 7-4, carrying the work engaging members 82, are moved against the sides of. the work by a Spring 78, said members 82 being arranged to engage the upper upon opposite sides adjacent to the ends of the counter. The rear ends of the levers Mare engaged by a lever 86, said lever 86 being actuated by a cam upon the shaft 3. When the I lever 86 is moved rearwardly,.it will be seen that the Work-engagin members 82 are independ cntly and yieldingly held. against the work Y he spring 78. l

It frequently happens that the rear seam of an upper does not extend quite to the heel seat edge of the upper so that a siit is left in its edge at the extreme rear. The crescent shape of the Wiper 88 is of advantage in preventing the tack-driving mechanism hereinafter described from driving a tack through this slit and consequently failing to secure the upper to the innersole. The Wiper in moving over the Work tends to gather toward the longitudinal central line of the last the portion of upper acted upon. 1

A casing 90 is mounted upon the carrier 61-, said casing inclosing a driver bar actuated by a lever 98 pivoted upon the frame and automatically rocked by a cam upon the shatt 3 cooperating with a spring arranged, to depress t e forward end of the lever.

passage in the casing 90 by any suitable mechanism, and the lower end of the casing 90 is'in line with an orifice in the wiper 68 through which the tack is driven through the wipedover upper, the counter and the innersole, and is clenched upon the heel plate of the last.

The stem 22 is provided with a longitudinally arranged driver passage terminating in the rest 24 and the driver bar 108 is arranged to work in said passage and to drive a tack part Way into the rear of the shoe at a point adjacent to the cone of the last. The

rest 24 and the driving mechanism operating therein are vertically adjustable in order to ivary the position of the tack thus driven into the rear face of the last. This vertical adjustment of the stem 22 permitsthe end tack to be driven, if desired, closely adjacent to rear seam during the pulling-over opcra-- tion. As will be obvious, the end tack co A tacit strip is intermittently fed through a-- operatoslwith that driven through UPPPL' and mnnlor into tho innorsolo to hold securely i 'n displacement the portion of the uiipor l in 5 between them, and by placing r the 0nd tori: :lgo to the (zone of the last as possililo, the rOa sham is cti'erlually held 'l".-oin, ois'placemo Tin arrang ent of the parts is preferv h that tho lflf'li drivou hy the driver har his is either per-p0udirular to the suri; A in 'ahi-i-h it is driven or is inrlinial to ward this solo oi the last. ilicoordingly in the wmstrurtiim shown tho stem 22 and its driwr iinSSflg-{U iii-0 inclined upwardly and will 'l io toature of driving tho tat-k i t l 'i l' l tho solo of tho last is of t iii that tho tendoncy to upward of of the upper producsrd by the in. 3' loving over tho edgo of the last a i v soii 113M ir-nds to draw the upper closely against tho last in the vicinity of a tack thus inserted the end oi the last. it will be obvious Fig. 3 that. it the tack ore otherwise arrangrd this etl'ert might not he sccurwh tor otvainpl i ii? the tack wort inclined in tho d3 toward the cono of i u'iovieniont of tho upper t rouse it to he moved away in la t slid in the x'irinily of the tank.

It will be understood that the straight counters are in temper when used, so that they may readily conform to the shape of the end of the last, and so that their upper edges may be bent over as stated. It, is n common practice to secure a straight counter throughout its length to the upper lining by means of adhesi ematerial, when said counter is planed within the upper. As will ho obvious this insures that the rounter will ren'uiin in the position which is given it; within the npprr. The parts of a boot; or shoo having heen brought together upon a last, the last is placed upon the heel pin of the machine shown. and may he then moved by hand rearwardly against the rest 24'. The counter and upper are thus brought into close relation to the rear face of the last. If desired, the subsequent vertical movement of the heel pin may be depended upon to raise the Work against the stop 26. It is preferred ordinarily, howrvvr, to hold the work manually against the stop 253 and rust 24 holoro the machine is started. sinro thoroliy lho position of tho Work with rolation to tho remaining Kirk-engaging dovii'os may lie manually controllm'l.

in tho further mommvntot the main shall liar u rlrongaging members 32 are The devices acting upon the Work at the heel and more particularly the wiper and presser tend to spread apart and move the ends of the counter downwardly toward the cone of the last. This is objectionable on account of the necessity of bringing the counter ends back into position before lasting. It is particularly disadvantageous where a flanged counter is used since, if the corners of such counters are depressed be low the edge of the innersole, they cannot be brought back into position by the laster except at the expense of some trouble. It will be borne in mind that the flanged or molded counters are quite stilt and if the flanges of such counters are caught at their ends, below the side edge of the innersole, they must be manually raised before lasting, in order that the counter may be brought closely against the sides of the last. An important function of the work-engaging members 82 is to prevent the ends of the counter being moved downwardly below the edge of the innersole.

The Wiper and presser cot perate to bring the upper into close contact with the last and to form a Well defined edge at the rear of the heel seat, so that in lasting the operator starts with a heel seat in considerably better shape than is commonly produced in assembling by hand. H e is thereby enabled to form better heel seats and also to produce them with less e'dort.

The machine herein shown and described is claimed in an application filed August 15, 1906, Serial No. 330,705, of Which the pres ent application is a. division.

Having described my invention, what I claim as new and desire to secure by Let- 11ers Patent of the United States is 1. The method of assembling parts of boots and shoes which consists in supporting an. inuersole upon the bottom of a making last, arranging an upper and counter about the last in unsecured relation thereto, holding the ends of the counter against the sides of the last, then pressing the counter against the rear face of the last adjacent its tread face and against the rear edge of the inncrsuie, pressing the counter against the the inncrsoie and thereafter ,ng the counter to the innersolc,

The method of securing a counter to an innersole in assembled relation upon a last which consists in holding the ends of the counter against the sides of the last, then pressing the counter against the rear face of the last adjacent to the bottom of the last and pressing the innersole against the counter, and thereafter securing the counter to the innersole.

3. The method of assembling parts of boots and shoes which consists in supporting an innersole upon the bottom of a makiug last, arranging an upper and counter about the last in unsecured relation thereto, holding the rear of the counterin close relation to the end of the last at a point re moved from the sole, pressing the sides of the counter against the sides of the last, thereafter pressing the counter against the rear face of the lastat the sole edge and securing the counter to the innersole.

4. The method of assembling parts of boots and shoes which consists in arranging an upper, a molded counter and an innersole in loose relation upon a making last, pressing the flange of the counter against the face of the innersole at the extreme rear of the heel, thereafter securing the counter and upper to the rear face of the last, straining the upper over the rear edge of the last and thereafter securing the upper and counter to the innersole at the extreme rear of the heel.

5. The method of assembling parts of boots and shoes which consists in supporting an innersole upon the bottom of a making last, arranging a lined upper and a counter about the last in unsecured relation thereto, wiping the upper and the ends of the counter forwardly along the sides of the last and holding them, securing the upper and counter to the rear face of the last, Wiping the upper and counter over the edge of the last at the rear end thereofland inserting a fastening through said upper and counter into the innersole.

In testimony whereof I have signed my name to this specitication in the presence of two subscribing witnesses.
