Letters Patent No. 99,682, dated February 8, 1870.

IMPROVEMENT IN MACHINE FOR MOULDING, ROUNDING, CHANNELLING,AND STAMP- ING- SOLES OI BOOTS SHOES.

The Schedule referred to in these Letters Patent and making part of the same Be it known that I, ALBERT J nrsnns, of Lynn, in the county of Essex, and Commonwealth ofltfassachusetts, have made an invention of a new and useful Machine for Performing the Operations of Moulding, Roundin'g, Ghannelling, and Stamping the Soles of Boots or Shoes, previous to their application to the'uppcrs thereof; and do herebydeclare the following to be a full, clear, and exact description thereof, due reference being had to the accompanying drawings, which make part of this specification, and in which- Figure 1 is a front elevation;

Figure 2, a side elevation;

Figure 3, a vertical central andlongitudinal section;

Figure 4, a.vertical and transverse section; and

Figure 5, a plan of a machine, embodying the'features of my invention.

Details" of this machine, as they may suggest themselves, will be'duly referred to.

Previous to entering upon thedescription herein contained of the nature and purposes of ,the machine which comprises the sulriect-matter of these Letters Patent, and 'consequentl y of my'prescntinventiom'l would say that Letters Patent of the'United States of America, numbered 83,172,.were issued to meon -the 20th day of October, 1868, for a machine for moulding, rounding, and channelling soles of boots or shoes.

Although certain defects, which 'were found to ex ist in the machine organized as shown in said Letters Patent, naturally suggested to my mind the invention herein described, and although a portion of the effects produced by my present machine are analogous to those effected-by the former, yet my last embodiment of devices and details should'ndt-he coupled with my patented machine,- inasmuch as the two possess very little, if anything, in common.

-The object of my present invention, as before prefaced, and as this context will explain, is to organize into a self-contained whole, devices or mechanism foreffecting the operations oi moulding, rounding, chanuelling,and stamping, as the operations are technically termed, the soles of boots and shoes; the first 'mentioncd operation consisting in conforming or shaping the general area. of the sole to tit the tread of a last; the operation second named, in cutting or plowing a groove or channel for reception of the stitching which secures the sole of aboot'to its upper; the third mentioned Operation.consisting in cutting, with the aid of a. travelling knife, the contour of the sole, in

order to adapt it to the outline of the last to which it is to he applied; the fourth andlast, operation con-' sisting in aflixing or impressing-upon or withint-he wearing-111cc of the sole, the number of the shoe which carries it, or any other character, figure, or design which taste or circumstances may render desirable or necessary.

For the purpose of clear elucidation and explanation of the machine, and to enable persons skilled in the cra-fi to which it appertains to make and use such machine, the following description of its construction and operation may bedivided into two parts, the first being that for moulding and stamping the sole, and the second, that of rounding and channelling such sol'e.

In the various figures of the drawings before mentioned, as accompanying this specification, and illustiating my invention, like figures, wherever they occur, indicate like parts. v

' Beginning with the moulding-portion of the machine,

the'reader, by referring to these drawihgs, 'will see that the frame of the machine is shown at A as'of suitable size and form to receive the operative parts, to be hereinafter-described; its general form, in front elevation, being similar to that of the well-known McKey sewing-machine, now in extensive use for sewing together 'the sole and upper of a boot or shoe, and to which my present invention is a veryvaluable adjunct.

The frame A, in its general construction, is composed of four legs or standards, a a a a, united attop by an annular rail, '1), upo'n which is fixed a broad flat table or platform, 0, either circular or otherwise.

The driving-shaft of the machine is represented at d as properly supported and revolving in boxes 0 e, up-

held by cross-bars, which bridge the lower portion'of the two opposite end standards a a, before mentioned, such driving-shaft being disposed parallel to and in longi-\ tudinal alignment'w-ith the main or primary workingfcatures of the. machinery, and provided at one extremity with fast and loose pulleys g h, after the man ncr of many classes of machinery, the former of such pulleysbeing the driving-pulley of mechani sm.

The opposite, (and in the present instance righthanded,) extremity of the driving-shait d, is furnished .with a crank or crank-wheel, f, for effecting vertical alternations of the mould-block to and fro of the forming-last, as hereinafter explained.

Tb each side of the outer margin of the platform 0 1 is aifixed an upright post, i while spanning the tops of these posts, and firmly uniting them, is a slotted crossrhead or open truss, j.

Embracing, and sliding upon this cross-head j, which thus perfoims'the office of ways, is arectangular tub ular-carriage or head It, the relative position of this carriage, with respect to the cross-head, being adjust.

cd by means of a male screw, I, which passes through a spur, m, fixed upon its rear side, the head or shank of the screw being in turn pivoted in a suitable manor making part of the rod ner to a second spur, a, fixed to the outer end of the cross-head. The purpose of thus applying the tubular carriage 7: adj ustably to the cross-head, is to permit of changes of the position of the mould-block which is carried by the carriage, and which will be hereinafter explained, the object in thus varying the position of the mould and stamping-block being to bringit into coincidence'with the shaping-last, with which it op crates. v

' The said moulding and stamping-block or-press is shown at 0, in the accompanyin g drawing, as swivelled to the lower end of an upright rod or spindle, 1), which is susceptible of vertical'reciprocations within a channel or bore, q, formed within the sliding-carriage k before mentioned, and preferably, in point of construction, at the left of the same. The vertical movements of this rod 11 being eflected by means of a pinion, q,

. and it should also be provided with a suitable hold-fast pawl or spring-catch, '.to maintain it at its highest altitude.

vThe under, or moulding, and stamping .or-embossing-surfaceof the press-block o is in general conformation a duplicate of the upper surface of the shap-' ing-last or bed,.snch two surfaces corresponding in form to the tread of the last upon which the boot using the sole is to he made. I

- The purpose in view, in swirelling the mould-block to its rod, is to allow of tilting-movements in any direction, in order insure its; perfect adjustment to the upper face of the forming-last,

As hereinbefore premised, the under, or moulding and embossing-surface of the mould-block 0 may be provided with a die, for impressing upon the sole its individual number, or that of the boot or shoe to which it belongs, or character or figures of any nature, may, by like means, he fixed upon the sole, whether the trademark or address of a manufacturer, or any ornamental design.

The existence of the central slot or orifice of the cross-head. j is" for the purpose of permitting traversions of the adjustable carriage and its adjuncts there-- upon. I

Upon the cross-head j, and near one end thereof, I erect a furcated post 'or upright guide, u, within which is disposed, loosely, at about its centre, a long, horizontal, oscillating lever or bar, 0, the forward or inner extremity of such lever being fulcrumed'to astanda'rd w, erected upon the'upper part of thecarriage k,

and near the central part thereof, and in close rela' tionship with the upper end of the rod pot the mould block, the union of the lever and post being a sliding or" yielding one, in order to permit of sliding movements of'the said lever uponits fulcrum, and over and upon the rod 1), or fromofi, and to one side of such rod, for the purpose hereinafter explained.

- Thetraversion or slidingmovement of the lever '11 is effected by means of a hanginglever or arm, :0, which is pivoted to it by'meausof a pit-man or link, one end of which is swivelled or connected to the lever t at about its centre, and the opposite end to the-said arm 0:, and near to the upper part of the same, the upper extremity of the arm itself being fulcrumed'to the -top' of the furcated post or guide a.

The onteror remote end of the lever 12 is connected,

by means of a connecting-rod, a, with the wrist-pin b of the crank or wheel f, hereinbefin'e mentioned, as

mounted upon the drivingshaft, this rode. being sus cept-ible of longitudinal expansion or contraction, in order to vary the degrees of pressure exerted by its agency upon the lever c, and through the latter the amount of power with which the mould-block is forced upon the sole, since it will beapparent, that as the crank-wheel f,- by its revolution, eti'ects, through such rod, the depression of the innerend of thclever c any prolongation of the rodproduccs such rigidity of its accessories as to effect an increase-in such pressure.

The expansible nature of the connecting-rod also compensates for any slackness or looseness of joints of thc'lever and its connections.

The receiying and shaping-last or bed-bloclvof the machine, which has heenherein alluded to, is exhibit ed at c, in theannexed drawings, as being of like size and shape with the mould-block 0, and mounted upon an oblong and flat travelling tablet 'or base plate, d, which is supported loosely upon the top of the platform 0 of the machine frame, the said shaping-last hav ing, upon its upper surface, a series of bristling spurs,

to securely hold the sole thereto.

Motions of this tablet and its last upon the platform,

through anohlong or elliptical path,'orconfbrmably to the outline of the shaping-last," are effected by means of a pinion, e, which rises above the surface-of the platform, and is fixed to the upper .end' of a short upright tubular shaft, f, this shaft passing through the 'teeth, which extend about its entire circuit, and par- ,alle'l, or approxiinatingly so, to its outer boundary.

Revolutionsof the pinion, by instrumentalities hereafter stated, produce corresponding ensuing revolutions or journeys of the tablet d, and snpportiug-iast c, the movement thus described being, as before stated, an oblong, endless path..

The tablet d 'is maintained in place upon th machine-table in part by a rail, j, which is securely oltedto the said tablet, an overhanging lip, reaching inward from the rail, and lapping upon a rib, k, which circumscribes the lower edge of the said tablet, as defined in' fig. 5 of theaccompanying drawings.

' The 'in'stu'mentalities for effecting revolution of the pinion-shaft'lf are organized as follows:

To such shaft, and near its lower part, is affixed a tubular huh, l upon the lower end of which is produced a series of saw-teeth, m m, which constitutes a semi-clutch, n, to operate in conjunction with a second and twin-shaped semi-clutch o disposed belo'w'it, and mounted upon the shaft or spindle g before mentioned. .These clutches are similar in construction and operation to those ordinarily'in use, and with which all mechanics are familiar. v

An annular groove, p','is cut in the peripheryof the hub l,;into which the fork q of a compound shipping lever 1" extends, the oflice of the latter-mentioned lever-,which is fulcrumed to the under side of the machine table, being to effect the locking or discngagement of the two semi-clutches.

The spindle g is driven by a bevelled gear, 8, fixed to'the driving-shaft (l of the machine. such bevelled gear meshing into a second bevelled gear, it, fixed to the said spindle g, as represented in the drawings.

Revolutions of the driving-shaft effect, by mcansof the gears s and t, sympathetic revolutions of the spindie, and by means of the semi-clutches a" o, corresponding rotations of the tubular shaitf..and its pinion, when, by the depression of the shimiing-lever 2:, the two clutches are thrown into engagement.

During the timet-hese' clutches are separated. the,

driving-shaft d and spindle g. are revolving without action upon the working-parts of the machine, except to produce titilations of the outer end of the lever c. u, in the accom 'ianying drawings, represents an upright bolt, the lower end of which is pivoted to the -shi iin -lever-r and whose u or end extends into,

, tablet, being thus'estoppedfi'om further movement bymeans of" thebolt, until the latter is withdrawn from the notch by the depression of the shipping-lever.

This depression ofthe shipping-lever effects a twofold purpose, that of engaging the two'clntches n and o, and, simultaneous therewith, lowering the bolt 11,

and, by releasing the hold-upon the tablet, allows the -latter to be revolved by the revolution of the tubular 1 shaft f, which is efiected by the action of the gears's.

and t. V

It will be'app'arent that the bolt,- in turn, performs the double oifice of, at one time, locking the tablet to clutches in contaet,'and' thus preserving iuoperatiou the proper instrulnentalities for effecting a revolution '01 such'tablet, 'itbein'g understood, and'as will he evi-' dent, to the reader hereof; that the depression of the bolt, which was efi'ected by means of the shipping-lever, is maintained by its own impact with the bottom of the tablet or its eucompassingrib k, untilsuclrtab let has completed one entire circuit, whieh,.as before stated, brings its notch into coincidence withthe bolt.

'to an arm, 2:, pivoted to and disposed alongside of the i shipping-lever r.

We'have now seen the nature and grouping of agencies for producing the descent and insuring ascent of the mould-block, to and from the shaping-last, as well as thelocking and unlocking of such last with respect to the machine-table, and its travelling movement in describii'ig its circuit about and by means of the pinion which drives it. I

It now remains for me to describe the construction and mode of operation of the devices which effect the cutting out the sole, and the production ofthe channel, which is to receive the stitching which secures the sole to the upper.

The combination of devices by whose agency I effect such results, comprises, as a general whole, the

.portion of the machine which I term the head block.

This head-block is composed first of a flat rectangu' lar sliding plate, 2:, dovetailed upon its edges, and sliding within a dovetailed groove, 3 ,formed in the upper part of the box or bed-plate z, .erect' d centrally upon the machineta-ble, and end on to the travellingtablet ll, and so disposed, with respect to the latter,

that the bottom of the said sliding plate x"shali be on a level with or slightly above that of the upper surface of the tablet, where it overlaps a short distance, or as shown in fig-4 of the accompanying drawings, when atits extreme forward position.

The sliding plate or carriage it is forced rearward .the machine-table, while the clutches are out of engagment, and, at another time, maiiitaining these and away from the tablet d, by the action of two coiled springs, 113a, disposed upon opposite sides of it, and with their outer-extremities fixed to opposite ends of a ClOSS-bill', b fixed to a rod or pitn'ian, c,

which, in its turn is pivoted tothe N r and onter'exbend to the underside of theinachine-htble, or astud' fixed thcreat,'the fulcrum of said lever' being closely contiguous to that of the shipping-levcr r, hereinbefore nientioiusd The.upper extremity of the outer and vertical arm 6 of the lever (P, passes through an orifice, f, made ;in 'the plate x, and at about its centre,' the remaining arm 9, of the said lever, extending to the front of the machine, and having aflixed to its extremity a weight or ball, 11?,- of snfiicieut gravity to aid considerably the action of the springs a a in retracting the plate x,

' this weight, however, being rather a desirable addi-' tion than necessary appendage ofthe machine.

A connecting-rod or pitman, i, connects the centre of the longer and horizontal arm g of-the bellrcrank' lever d. with the inner end of a treadle, j, disposed at the lower part of the machine-fiame,,and pivoted at about its centre, to a cross-bar, uniting the'lower portion of the two front legs of the machine-frame, the pedal of this treadle extending into such a position in advance of the machine, as to enable the attendant of the same to readily place his footupon it.

By placin r the foot upon the treadle and elevating its inner en and with it the longer arm of the bellcrank; lever, the upright arm of the such lever is vi bratcd upon its fulcrum, its ensuing retraction causing alike retraction of the sliding plate x, and its acces.- sories, for the purpose of removing with it the channelling-tool and knife from contact with the sole upon the shaping-last after the necessary operations upon such sole have been completed.

A stop-pawl, k is pivoted to the cross-bar last mentioned, and in close proximity to the pedal of the treadle, and is for the purpose of maintaining it in a depressed position, and consequently retain the sliding-plate z and its adj nuct in the rearward position when circumstances require, against the power of the springs a a, and the, gravity of the weight It, exerted to force it in a contrary direction.

To the upper and ti'oTit end of the plate 2:, a horizontal" and second and swinging plate, I, of similar. character, but shorter, ispivoted, also at its front'end,

in such manner that its rearend is free to describe an arc of a circle upon the lower plate.

Within the upper face of the plateli, I dispose a third plate or cutter-head, m, the connection and dis-' position of these two last-mentionedlplates beingsim? ilar to that of the said plate P, andthe lower sliding .plate 1;, they being provided with springs 'n n inlike manner as with said lower plates, and for the same purpose. The proper position of the upper plate, which I term the tool-camen'inasmnch as it carries the rounding-knife and channelling-instrument upon the middle plate, being determined by pins 0 o, fixed to the upper surface of the latter, and extending into slots or notches p 1), made in the said upper plate, as represented in Figure 6, of the drawings, which is a plan of the two.

The rounding-tool or knife for cutting or turning the sole close to the edge of the bed 0, is shownat q", in the. drawings, as mounted in a. suitable manner, and in an upright position at the front end of the upper plate or cutter-dread m, and so that, when the latter is in its extreme-forward position, suchflknife shall be .iu close contact with the edge of the forming-last c.

1 The holder or chuckjfor supporting the channelling into engagement, and

. wrist of the crank-w inner end of the lever i inaugurated by tool or plowing-instrument is denoted by the letter T, as pivoted to the lower end of the tool-carrier, which, as represented in the present instance, is a bent or curved bar 3, making part of or extending outwardly from a tubular standard, it, which slides upon an upright rod, it, er acted upon the cutter-head or plate m.

The said tod -holder is depressedtoward the cutterhead or the shaping-last when surmounting it, by a coiled spring, '0, which encircles the upper part of the rod n", and rests upon the top of said tool-carrier.

As the construction and operation of the channelling-instrument carried by the clutch p and which 0perful descent of the mould-block upon the sole-blank, and toward the bed 0, thus e 'nbracing and compressing between them suclrblank, by this operation, not only moulding the said blank to the general surface of the last, to which it is subsequently securely confined by its spurs, hilt also impressing upon orint sole the figure or characters-with which'the bottom of the mould is provided.

The moment the wrist of the crank-wheel arrives at its highest point, the pressure of the lever vupon the mould-block of necessity ceases, and the attendant, "at this point, releases his hold of the handle or arm x,- which permits the spring of the said lever to retract crates upon the upper surface of the sole, which, at the time; is upon the last 0, to form the stitch-receiving channel therein, is fullyexplained in Letters Patent of the United Stat-es, issued to William Duchemin and myself,- on the.27th day of August, 1867, for an improved mode of channelling soles, a detailed description of such instrument is not considered a necessary or pertinent part of this specification.

I would remark, however, that the channelling-tool is to be applied to the tool-carrier, and in combination with a movable guide, in such manner as to allow of its position with respect to such tool-carrier and guide being varied or changed, in order to regulate the depth of the channel to be cut, as well as for other useful purposes.

Having thus described the mechanical construction of parts which embody a working and self-contained whole or practical machine for carrying out the object of my present invention, I will now describe the operation of such machine.

The normal or starting position of the tra'velling tablet is thatshown in lig.'5v of the accompanying drawings, that is to say, with the toe of its shapinglast 0 at the right of theoperator, and with the ball of such last about op posite the headstock, hereinbefore mentioned, the locking-bolt it being, at this time, within the notch 11 of the tablet, and locking the latter immovably to the table of the machine The piece of leather or sole-blank, having been previously moistened by immersion in water, in the customary manner, isto he placed upon the forming-last or bed 0, or upon the sharp spurs which crown it, and preferably, pressed. somewhat about them.

The operator now seizes h'ol d'of the hand-wheel of the pinion-shaft, and, by means of such pinion, produces adescent ot'the mould-block upon the sole-blank, the upper end of the spindle p of such mould-block, by this act, being brought immediately below the path of forward movement of the lever 13,

This havingbeen accomplished, the operator next seizes, withinhis right hand, the handle of the lever or arm :0, and, by depressing" it,- drives forward the lever 1!, until its inner end is ,o ifer, and coincides with the spindle of the mould-block, the hold. of the arm being maintained until the proper time comes for its removal, as hereinafter stated,which is effected by a coiled spring applied to the lever 11, and the furcated post a, as exhibited in the drawings. I

With his hold upon the arm preserved, the atten dant now depresses the out-er forward end or handle of the shipper 'r, by this act; forcing the two clutches putting the shaft-and pinion in revolution, and atthe same instant, and by the same set withdrawing the'holt from contact with tin? tablet, and leaving the latter free to begin its movement consequent uponrevolution of the pinion e, the heel f being in the position shown in the drawings, or as in readiness toefl'ect the cieva tion of the outer, and the ensuing depression of the A commencement of revolution of the driving-shaft ordinary mea'ns first, by means of the it to its normalposition, and out of concidencc with the spindle of the mould-block.

The next act of the attendant is to elevate the mould-block by the same agencies-that lowered it, the sole-blank remaining upon the shapiug-lasu'to which it clincs' with a sufiicient tenacity to remain in place thereupon during the manipulations to WI jectcd. p l

The duty of theattendant isjnow to remove the stop-pawl or dog from contact with the- 'treadle, and allow the force of the' springs a afiand the gravity of the weighth, to advance the head-stock, ar d force its knife orrounding-tool in close" contact with the edge of the shaping-last, care being taken by'the attendant that the channelling-tool,carried bythe chuck before mentioned, be elevate upper surface of the sole-blank. v

The continued revolution of the driving-shaft, and, as a consequence, through ins mentioned, of the tubular-shaft f and its pinion, effects revolutions or journeys of the tablet d and shaping-last u, about the pinion, and, as before stated, in an oblong path, the yielding conpections of the "arious component parts of the head blochallowing the cutting and channeling-tools to conform themselves to the curvature of the boundary of said last, and to operate in parallelism therewith.

The tablet and shaping-lastcontinue their journey in unison, until a complete circuit has been made,"and the notch r, of the tablet, arrives over the bolt u, when the latter, as well as 'the shipping-lever r, is elevated, thus, at one movement, locking the bolt into said notch, and disengaging the clutches, the tablet coming'to a stop, and being locked inimovably in position, thus bringing us to our starting point.

During this circuit of the tablet d, the roundingtool or knife has cut the sole closely to the edge of the last, while the channelling-tool has, at the sametime, out within or from the face of such blank the continuous or endless channel to receive the stitching.

his foot upon the treadle The operator now places j, and depresses it to such an extent'that it islocked in position by its holdrfast; pawl, the lowering of the treadle having the effectof retracting the head-block, and its adjuncts, including the rounding and channelling instruments, from proximityitotbe sole-blank and tablet.

The sole is now forcibly removed from the spurs of the last, when itwill be found to have received, not only the impress of such formed upon thelower face of the movable block, but an endless channel, as'beforc stated, and'to have been out to the outline of the last.

The advantages of the machine comprising the subjectof my present invention consist, as beibre prefaced, mainly, in the fact that the four operationsare Coilibined. in one machine, and the work performed in one complete movement or ci rcuitof working-parts of such machine, the number of machines are reduced t'o onethird that now required to do the same work, with a aforesaid crank-wheel and lever r, effects a very p'owconsequent diminution of the amount of capital re; quired to conduct the business.

0 such p rich it is subd, and deposited upon the trumentalities before last, and of the character actuated by the rack t,

ling, and stamping soles a shipping-lever, with th Its use also diminishes to about that ei ttentthe size of the room occupied by such machines, with a consequent diminution in the amount expended for rent of such roomsor building; the number of operators being reduced to one-third that heretofore required, making a savingiof expense of great magnitude.

The work is also performed. by the machine in the most thorough and perfect manner.
