.machinesffor operating upon the soles of In the manufacture of shoesfhaving Wooden :Louis heels, it is-usualto face the breast of the heel with a Hap split from .the heel-.seatrportion of thesole. and to shape the body-of rthe heel-seat as an elongatedtongue that Will fitv Within the cup ofthe `Wood heel. This involves .the Vvoperations of splitting'the heelseat end ofthe soleto form the breast Hap and v.cutting the outline ofthe tongue in .the `body of the `heel-seat. In one'o'f its aspects, the present .invention consists in .a 1machine organized for performing Vboth the flap-splitting and tongue-cutting operations upon a .sole .presented thereto. To .this end, "an 1m- :portant feat-ure of the invention consists'fin ,the .combination .ofa splitting knife and a tongue-cutting knife, .together Withmeans for relatively vmoving ,theI sole .and splitting knife, and then relatively .movingthe .soleA and .the tongue-cutting knife to effect theV spli-tttingand tongue-cutting operations.

As herein sho.wn,'thegsole.is presented'by a Y movable carriervtothe splitting knife informing the iap, the knife is then removed from Y the sole and a tongue-cuttingknife,is.brought into action to form -a tongue inthe heel-'seat While the sole remains inthe position occupied at the conclusion .of the splitting .operation. By such arrangement of parts, a

compact and unitary'mec'hanism is securedv whereby the desired Operations may beperformed-in closesequence, in an accurate -rnannerand ata single'fpresentation of the sole.

In formingla tongue in-the heel-seat, itis desirable in some types of machines to dieshape the material, so distorting the .sole that a tongue of the required shape maybe formed Vby a single movement of'a straight .tongue- In this connection, the in vention contemplates as a further feature, a Y

cutting knife.

carrier for a sole having adie opening formed vtherein which is'closed during the splitting operation and Which may be opened at the conclusion of the splitting operation so that a portion .of the heel-seat may be forced into the opening and shaped forthe action of the tongue-cutting knife. This construction is j'limina-rily Y train of `mechanism operative .uponthe sole.

y from 'the machine.

Vbelieved to be broadly novel and yis of importance in that it permits the tongue-'cut- Y ting operation to be effected While the sole is retained uponits carrier in the'same position in which ithas been'loc-ated and clampedfpretothe splittingoperation.

j The splitting'knifeisherein vshown as-supported against the .thrustof the sole vby a n toretract the knife at ,the eonclusionof the splitting operation.` This* frees Vthe 'sole of Vthe splitting 4knife'sothat 'another operation `canloe conveniently performed upon 'i-t. .This '.feature, therefore, is not limited in its application `to machines for fitting the heel-seat of soles but may be usefully embodied in Ysplitting vmachines Where 4itis desired V.to splitting `operation lby seme other .operation The invention also includes,7as a `,feature ofgeneral application, a sole carrier having sole clamping means of novelcons'truction arranged to permit the sole Lto be located freel.ly and accurately in position Aand thenact- `ging automatlcally'vvhen -the machine-is'started andat a predetermined ,point inthe travel of the carrier to engage and reliabrlyma'intain the solein position .upon lthe carrier.

. vThe invention also contemplates a sole :pressing `member locatedadjacent to the splitting knife and serving-to controlthe `position of the splitting knife .as 4the-sole is movedy into .splitting position, so as to regulate the thickness of :the flap being split. vA

further 4feature of novel constructien consists in mounting Athe lpresser Ymember for bodily movement away fromthe sole at Lthe conclusion of the splitting operation v.so that the Work may be released and freely .removed In conforming the breastflap'lto the curved breast surfacefof a Louis heel, it is desirable to fmold the flap @both longitudinally and transversely into conformity tofthe contour of the heel breast in order to improve the supplement the smoothnessof thelitting and create atenden cyfor the flapto hug the heel surface:in-

. stead of standing oft' from it. To this end,

the. invention Icontemplatessole feeding or presenting Vmeans combined vwith molding lli mechanism organized to Vmold a breast flap t-o act automatically in timed relation to the splitting mechanism. Y This arrangement is importantvfrom the standpoint of securing a compact mechanical organization and one wherein the flap is positively controlled in its movement and position from the point-at `which it is formed Yuntil it'y is completely molded for the reception of the heel.

While the mechanism for splitting, tonguecutting and flap-molding have many features of novelty considered as unitary mechanisms, their cooperative organization 1n a -single machine is believed to be broadly 'new and constitutes one important aspect vof the invention. Itis, moreover, believed that splitting, mechanism'and" flap-molding' mechanism have not been heretofore associated in Fig. 9 isa view in 'perspectlve-4 of the Vrear end of a sole which has-been operated upon cooperative relation and thisv combination constitutes another broad aspect of the 1nvention.

The invention includes also `within 'scope the novel method of preparing soles for wood heels herein shown as carried out by themachi'ne disclosed, but obviously the method is capable of being practiced by other or different instrumentalities.

The invention will be best understood'and appreciated from the following description of one form of machine embodying it, which has been selected for purposes of illustration and which, together with the method of using it, is shown in the accompanying drawings, in which- 1 Y Fig. 1 is a view in side elevatlon, partly in section, ofthe machine;

Th machine inl general comprisesa frame 1() in which is mounted a cam shaft 1:2 carryingk the various cams of the machinev and Vdriven throughv a 'one-revolution clutch, not

shown, of any `commercial construction.- The `forward portion of the machine frameis provided with horizontal dove-tailed ways 14. in which is mounted the carrier slide 16 having secured to its upper face a carrier plate 18 -upon which the scle is positioned preliminarily to its presentation to the machine. The'plate 18 is roughened orcorrugated upon its surface to'retainpthe sole vmore vsecurely and adapted to be reciprocated with the slide 16 forwardly and rearwardly. The slide 16 is actuated automatically by a cam lever 17 pivotally mounted in the frame 10 at its lower end upon -a studV 19 and connected at its, upper end through a link 15 to a pin 13 carried between ears projecting from the lowe'rside of the' slide A1b. The cam lever 17 is provided with a cam roll 21 through which 'rocking movement is imparted to thelever by a cam of suitable contour on'the cam shaft. lllhecam is so shapedfthat on starting the machine theV carrier is vmoved inwardly, presenting the sole first to the splitting knife and then dwelling in its inmost position, as will hereinafter appear, for'the purpose of permitting the flap-molding and tonguecutting operations to ltake place. Y

In order toV grip the sole upon the carrier plate 18, a pair'of clamping devices 59 are mounted upon the carrier slide 16 and arranged to move into clamping engagement with the sole at a predetermined point in the inward -travel `of the carrier. The clamping devices each comprises an-arm pivotally connected to the outer end of a transverse clamp slide 51 and having also an intermediate link 61 connecting it to the'plate 18. A compresif.

sion spring 53 is interposed between the inner ends of the clamp slidesi 51 and this acts contlnually to urge the clamp slides outwardly and, consequently, to swing the clamping devices upwardly into releasing position. Each clamp slide is provided at its outerend with a roll 55 which'runs upon the face of a cam plate 57,' thus limiting thel outward movement ofthe slide at all times and having an inclined face which acts when the carrier mounted a clamping foot 53, backed up by a spring of'suiiicient tension to allow for soles of varying thickness and at the Sametime to' exert lsufficient clamping action upon the sole :to Vhold it reliably against displacement in Vthe position inwhich it Vhasbeen located in the carrier.

The splitting means for supporting and moving it will now be described. The knifek 71 is secured to the lower side of a knife carrier 73 mounted to slide forwardly and rearwardlyin guideways formed'in a bracket 75, which is carried knife together with the* merano by the machine iframe and :mounted y.therein `upon .a transverse shaft @111. The knifefcarj tongue-cutting operation to take place, as

Y so as ,to break the ltoggle links and .retract 'a solepressing rol`l91 CCI will presently appear. A `pai1.-oftoggleli-nks 77 are interposed between the rear :end of the :knife slide 73 and a stationary'stud 79 ,in .the machine frameand are connected atrftheir joint through la link 81-with a .rockinglever .83 `pivoted at .its forward 'endto the machine frame by atransverseshaft 85. The rock-ing lever 83fcarriesan .intermediate cam roll .84 whichis rocked by acam on the cam shaft 2 at theproper -.time in the cycle ofthemachine,

the splittingknife. It will gbe observed ,that the straightened .toggle links constitute a rigid support for lthe' splitting knife .at all other times.

In order to controlthe presentation of the sole to the splitting knife and to regulate the vthickness Vof a flap 40 being split, which flap will ube referred Vto las a heel-,seat `Hap, isprovided at a point above the carrier slide .and adjacent to the edge of the splitting knife. This 'is `carried `by :the bracket 7 alreadymentioned Ias .being pivotally supported upon thes'hatt 111 and which, at its forward end, -is provided with a head 76, see "Ehe head 76 `at each side is `provided with vertical guide-ways in which are mounted s'lides 93, each formed kat its lowerend toconstitute a bearing for a 'trunnion 95 of the presser rollj91 and having an inclined tace aft'its upper end. Each slide 93'is normally pressed upwardly by a spring, not shown'7 and is limitedin its vertical movement by engagement with a wedge-shaped face, one of which is formed at eaeh yend of a cross'bar 97. 'The bar -97 is also mounted .in the head 76 .and'guideditor transverse movement, which .is effective in one direction Y to force the slides 93 downwardly and inthe other to permit them to rise equally .in Vtheir vertical,guide-ways.` The vertical positionof the sole-pressing roll 91 Vmay thereafter be adjusted by moving thebar 97 transversely.

1n order to provide orquick adjustment of this bar,it is provided withan u pstanding f lug 101 ,into which is threaded a spind'le'103 freely rotatable in a lug 105 ,carriedfby the bracket 75 and having a hand wheel l*107 at its outer end. l t t `Upward movement of the bar 97 and', consequently, of the beraeket"75 and-the .presser roll91 carried :thereby is limited and opposedby a spring-pressed plunger '113 which is mounted in a chamber in .the front Ypart of the machine frame and pressed downwardly by a compression spring,` 115 the effective strength of which can 'be adjusted a screw 117 This arrangement permits a limited take place ,can be controlled yielding movement of `the presser roll away from the carrier slide to compensate for yvariations i-n thickness of the soles being foper- :ated upon and as the bracket a7 5 .carries the splitting knifefwit'h it, iit lwill .be 'apparent .that the thickness of .the flap is maintained uniformand that any. variations which occur fare thrown Yinto thethickness of the :body of lthe-heel-seat remaining beneath it.

It is desirable that .the presser roll :791

should -be lifted so Vas not'to en'gage'the sole when `the latter is "being withdrawn fatter, -the various operations have been completed. ,Aocordingllthe Vbracket .7 5 ,is 'formed with a rearwardly rextending farm 1119 :which is 'con-r :nected at its rearend through lin-k 121 to one arm 1230i a lever pivoted ftothe imachine frame upon a lstu-d 125, and carrying on .its

In order -to .provide automatically for varying thethickness of the iiap longitudinally, the axisof .thepresser rell l91 isdisposed 'eccenltrically with respect to Vthe axis J.of its trun- .nions95- The right-hand trunnon has .lixed to it .a downwardly .extending aum 131 carr-ying at itslowerend a, cam :1011.133 which' .fr-.uns in a ca m slot 1.35 formeel in a-cam plate 137 a'djustably secured by .a Wing nut 139 ,passing .through a `slot in lthe plate in Aadjusted position .upon the .fcarrierslide 16. ln .theconstruct'ion herein shown, .the .slot 135i .acts .to l,hold the arm 2131 instationaryposition duringfthetirst partofthe inward movement of the carrier slide, aslthe .slotis horizontal and parallel to the path of theslide.

At its forwardfendthe slot y135 ,turns down-- wardlyand its diront wall 141.actsa1ponthe roll 133 when thefcarrierslide has .been moved Y downwardly with respect to vthe carrierslide and the sole .so .that'thethieknessfof vthe flap t Wfillbe` correspendingly increased. It will be ocking the' 2 observed that thethickness v sofia Vflap llofngitudinally can be .contrelledas 4desi-red 'by lsui-tv fablyshaping the camslot'l andthat the point ,at which the.thickeningcommences to A,by .altering Y,theeplosition otthecamplate 13.7 ,longitudinally on the carrierfslide. adjusting the angular 4position of'thecam plate137 about theaXis 'ofthe wing nut 139, aapvorf pro- Lgressively increasing thickness may v be formed. i

Should it be desired to vary the thickness of the flap transversely, the presser roll 91 may be correspondingly shaped. these circumstances, the resiliency of the sole may be relied upon to cause its transverse surface to conform to the-longitudinal shape of the roll or, Where that resiliency is regarded as insufficient, the effect may be intensified by suitably vshaping the transverse surface of the carrier plate 18. If it is desired to thicken the flap at acentral. zone, the contour of the face supporting the sole may be correspondingly shaped. n

In order to obtain uniform splitting, it-is desirable that the cutting edge' of the splitting knife 71should be located as closely as possibleV to the line of maximum pressure between the -presser roll 91 andthe carrier slide. To this-end, the rear face of the roll Y tween the upper surfaceof the knife and the may be carried out with the sole in placeV 91 is backed off, as indicated in Fig. 1. Gonsequently, the splitting knife may be ad-y vanced close to said line of maximum pressure without danger of the flap binding beroll. l

In order that the tongue-cutting operation upon the carrier slide, the reargend of the plate 18 is provided with'a die opening 23l havingva contour of the shape which'Y it is desired to impart tothe heel-seat tongue. To

i support the sole'during the splitting operation, this aperture isV closed by a movable filling plate or shutterV 25, normally'fiush with the surface'of the plate 18, so that' the plate and shutter constitute an uninterrupted support for the sole. At the proper time in the cycle of the machine, the shutter is displaced to fmake the ydie opening 23 effective, so that a portion of the material of the heel-V seat maybe depressed into it as will presently appear.

The shutter 25 is mounted upon the end of a lever 27, pivotally supported upon the pin .V13 of the carrier slide and having a short depending arm 29 at right angles thereto.

'- Pivotally connected to thelower end of the armV 29 is a v forwardly-extending lspringpressed stop 31, so located as tocontact with a stop pin 33 fixed inthe frame of the ma- Chine.V The arrangement is such that on the l movement of the carrierslide `into its outward position, the stop 31l engages the stop v pin 33 and swings thelever 27 upwardly, carrying the` shutter into the position shown in Fig.`-1. The shutter is provided with a cen-Y tral raised portion and with a transverselyextending rib 35 which contacts with the under surface of the'carrier plate18 and soV limits the upward movement of the shutter, the spring stop 31 supplying a slight amount ofV lost motion to insure accurate seating of Vthe shutter.

Under.v

' The shutter 25 is held positively in its uppermost positionV when the table moves inrib 35'to pass by whenthe shutter is raised.

The outer end of each plunger is provided with a downwardly projecting lip 41 which contacts Vwith, a cam-projection 13 (Fig. 2) located at the inner end ofthe` guide-way and moves each plunger outwardly when the carrier'slide reaches the limit of its initial i movement, so that the shutter is free to fall by its own weight from theV die opening 23.

The'tongue-cutting knife 151 is secured to a knife carriage 153 mounted for reciprocation in horizontal Vguide-.ways 154 formed in the frame of the machine. The knife carriage 153-is connected by a link 155 to the upper end of a rocker lever 157 pivotally mounted upon a stud 159 in the frame of the machine. The rocker lever 157 has a for-` wardly projecting arm which carries a cam roll 161 acted upon by a cam on the cam shaft 12 at the proper time in the cycle of the machine to rock the lever 157 and advance or retract the knife slide 153. The cutting edge of the tongue-cutting knife 151 is at such a height' that it moves practically in Contact with the under surface of the carrier, plate 18 when the carrierslide is in its inmost position and, consequently, the material forced through the die opening 23 is within itsrange c of action. Y

The means for forcing or bulging the material of the heel-seat through the die opening for die-shaping this portion of they heelseat will nowbe described in connection with the mechanism for molding the flap split fromthe heel-seat. The machine frame isformed with verticalbearings for a plunger 171 located in line with and above the point reached by the heel-seat of the sole at the conclusion of the splitting operation. The plunger 171 carries at its lower end a-die member or bulger, shaped in armanner wellknown in lthe art, forforcing or bulging the Amaterial of the heel-seat intothe die opening. The rear face ofthe plunger is provided with rack teeth 173 which mesh with'the teeth of a gear segmenty 175 formed in the face of a rocker lever 179 ivotally mounted upon a transverse shaft 1y 7 in the machine frame. The Vsegment is connected at its rear end by a link 181 to one arm of the bell crank lever 183, pivotally mounted in the machine frame upon thestud 185, and carrying in its other arm a cam roller 187 which is acted upon by a cam on the cam shaft 12 at the proper timey in thecycle of the machine torimpart ver-- tical movementtofthe plunger 17 Theflink 181 is of atwopart.construction,.the arrange ment being suchthat the plunger 171 is yield-V lingly depressed andpositively'raised.

It will be apparent that in designing the machine hereinabove described, it Was necessary4 first to evolve a method of preparing soles different from that heretofore practiced and involving a different sequence of steps.

The illustrated machine comprises .one combination of suitable instrumentalities for practicing this novel method .but the method maybe carriedout by other and-different instrumentalities.Y In this connection, particular attention iscalled tothe steps of splitting the ap from the heel-seat end of a solev and' inserting lthe flap ..as formedpbetvveen molding members., rlhis procedure, withits obvious advantages, is believed to be broadly new regardless of means for; carrying it out. The sameV is true with respect to performing simultaneously theoperat-ions of molding the iiap and die-shaping the body of the heel-seat in Whichthe tongue is to Vbe cut.
