kThis inventionre'lates to they manufacture of shoes and is illustrated as embodied 4in a heel seat fitting machine'organized to trimVv surplus material from the peripheralr portions ofthe heel seats of soles of shoes to pre pare theinfor'the attachment of Wood or other similar heels. Y K f Before attaching Wood heels to slices, it is usual toy trim the surplus material fromthe peripheral'portionsoftheheel seats of the soles of, the shoes, at the' same time beveling the heel seats to cause them to conform to the concave attac iingsurfacesfof the Wood heels. This permits thel upper edges of the heels to be broughtinto'direct contact vvithv the material of the shoe uppers 'so that the sole'is'not visible between' the'fheel and the upper. It is necessary thatr enough stock Abe ieniovedfrom the heel seat portion of the sole to permit'y a tight'joint between the edge of the heel and the shoe upper. it the same time' it is highly desirable that no morelvthan enough be removed; @tlierivisethere Wi jl be a left between the attaching face of the heel and thc-heel seat' portion of the shoe which iv'ill'tend to Weak-en the shoe. The stock thusremoved treni the periphery of the heel portion of the sole isapproximately of a horseshoe-shaped form, a cut or cuts being` made `traiisversely `of the sole at the heel breast line toA permit the complete separation from'the sole of the chip or' cliipssevered byV the peripheral cut and to form an abutment against which the' breast ofthe' heel is posi-y tion ed when the heel is attached. I

lt is an object of the pres'ent'invention to improve the organization of heelseat fitting machines parti cularlyyvith respect to the op# erating instrumentalities Aor" the machine Which perform the actu al cutting or Vvtrimming and also with respect to the parts of the machine which control the Work during` the' trimming. Y

A feature of the' invention comprises la drag knife and means for moving it peripl'ierally of the heel seat of the sole ci a shoeso that the trimming cut is'started at one end of the heel breast line and extends rearwardly,

around the heel ,end of the sole, and forA Wardly onthe other side` to theother end'effthe heel breast line.. To facilitate theV trimming operation, other features' ofthe invention comprisemeans for depressing the central portion of the heel seat of a sole relatively to the peripheral portionvvhile the surplus material is trimmed therefrom bya cutter 'such as a drag knife traveling peripherally ofthe heel seat. Preferably and as illustrated herein, means is also provided, acting in opj'giosi-y tion to the depressing means, for supporting the periphery of the heel seat of the sole dur'-l l ing the trimming operation.A

Another feature of the invention comprises i a heel seat fitting machine organization in which are provided knives movable transversely -of 'the' sole to be operated upon t'o mounting said knives to permit theV angular adjustment of theknives about aplurality of dierent aXes so as to' permit'L the knives tofbe adjusted to Whatever position may be necessary to suit the requirements of the Work inuhand. Thus .in the illustrated machine, the paths of mo'vement'of the knives for mak; ing the breast cut may be adjusted length-Y Wise of the sole to vary the point at whichl also the paths of the-knives may be angularly adjusted about' a vertical' axis so as` to vary the angle of the heel breast receiving cuts relatively to the margin of the'solein accord-A ance With the Aform of the breast ofA the heel and progressing around the periphery of theV rear end of the sole to a similar point at the otherside of the sole. In accordance` Withj'apreferred exemplication of the method the rear end ofthe sole lis distorted to bring the v'make theheel' breast receiving'lcut or cuts, this organization including novel means for the knives enter the material of the sole, and

periphery thereof above the central portion and a trimming blade located inthe depressed central portion of the sole cuts through the distorted periphery to thev outer edge and is moved progressively around the ing aheel breast receiving cut, showing adjusting slides; Y Y

' Fig. v7 shows a s hoe being removed from` the machine following the completion of the he'el seat fitting operation, in which there was used'toY make the heel breast receiving cut a type of knife provided with angularly arranged cutting edges designed to make a short stiff Hap beneath which the projectf ing end of the breast of a heel, such as a Louis heel, may be inserted; and

Fig. 8 ,is a diagrammaticv view, with parts in section,l of a shoe fitted in theV fashion showing a wood heel attached thereto.

vReferring first to Fig. l, it will be seen that the frame of the. machine comprises a substantially horizontal table -lOsupported upon vertical side frames 12 which are joined by central'portion of the table of the machine is recessed anda substantially circular ledge is provided adjacent to said recess to receive the correspondingly shaped edges of crease plates 20. These plates are provided with grooves 24 (Fig. 6) adjacent to their edges and are held for movement along the ledge by means of a curved plate 26 having a depending vrib. v28 entering, said groove 24. Eachof the crease plates is recessed and provided with a tapered projecting edgeportion 30 (Figs. 4 and?) adapted to enter the rand Vcrease of ashoe.' The recesses of the plates aresol `shaped that lthe projecting edges meet at a point 32 (Fig. 6) located exactly at the center of the recess of the table 10 and at a point corresponding to the back seam of a shoe tobe positioned by said plates. An actuating lever 84 (Fig. l) is provided for moving the crease plates in and out so that they may be'forced into the rand creasev of a shoe positioned inthe machine, and this lever isV attached to a transverse rock shaft 36 having rock arms-38 secured thereto at 39 `mounted upon lasts and have their soles` attached to their uppers. Support-ing means for the last of the shoe comprise a last pin resiliently and 'adjustably supported at the end of a swinging arm 52 pivotally mounted on a transverse shaft 54 'extending between the side frames l2 of the machine. By means of this arrangement, shoes having various sizes of lasts may be adjustably mounted upon the swinging arm 52 so that the rand crease of the shoe will be in position to receive the reduced edges 30 of the adjustable crease plates as they are forced into position Vin said crease by means of the actuating lever 34. At the same time, it should be noted that the resilient support for the last pin 50 allows the sole to bedistorted, as will later appear, bythe depression of the central portion of the heel seat of the sole against the tensionof the resiliently supported pin 50.

.After al shoe has been positioned in the machine in the manner above outlined, power operated mechanism is set in motion to actuate the varioustrimming knives to perform `the heel seat fitting operation. To this end a motor ismounted upon'the machine and is connected by suitable gears 62 to a horizontal cam shaft 64 supported in a suitable bearing 66 extending between the cross braces 14 of the machine. A one-'revolution clutch, indicated at 68, may be interposed-between ythe gears 62 and the cam shaft 64 and consuitable'braces 14 at the front and back;l The I trolled by means of a latch 70 mounted upon a -spindle 72 which is rotated to hold the latch normally in operative position by means of a spring T4. Mounted upon the outer end of this spindle 72 is an arm 76 underlying the forwardly projecting end of a latch 78 adaptedto be actuated by means of a foot treadle 8O to which it is pivotally connected at 82. A spring 84 holds the latch in position for engagement with the arm 7 6 and a pin 86 upon the frame of the machine cooperates with a cam surface upon said latch to pull it out of engagement with the arm 7 6 after the clutch has kbeen tripped in f seat portion of the sole priointo the insertion (ilA to position by the spring `74 tostop the caniVV shaft after it has completed kone revolution.

Knives of various styles inay belutilizcd for inalring the heel breast `receiving. cuts.- ln the arrangement shown in Figs. i, 2, 5, and' 6, these arefiat knives 90 having` upright,-

suitably shaped earns 102 upon the'cain shaft (ill. J@adjustzfole. guides are provided for the slides 92 vso that, When the'cain4 shaft is rotatechthe vknives will be reciproe'ated in predetermined paths cutting the lateral edges offtlie sole.'andoforining` abutiiients,=such as are illustratedat 104 in Fig; against 'which the breast of a heel'to` be lattached may be positioned. its is customary in Work` of this kind with Louis heels are to be attached to shoes, a flap 106'hasl been split freni the heel of the shoe in the heelseatiitting machine, it being understood that this flap utilized for covering tlierbreust of the heel after the latter hasbeen attached; it will beevident that heels of various sizes will .vary in length so that it will be necessaryto adjust the position ofthe' slides r92 in accordance with the length of the heels tobe handled. Topthis end guides 110 are mounted upon slides 112V dovetailed in the table 1.0 of the machine so that theyfinay he inovet1 forward and back along lines'parallel to the longitudinal axis of the sole of a shoe,and set screws 114 (Fig.

2) are provided for holding said slides in ad'usted Jositioir Aside frein v riations in the sizes of the heels to be acconiinodated, it will be evident that heels of variousstyles niay requirethat the paths of the breast cutting knives 90 shall be angularly adjusted about vertical ages to position the abutinerits i011 to coact With heels having a curved breast line. ,To this end the guides 110 are carried by curvedrsupporting nieinhers 115 provided `With outwardly flaring edges adapted to be received in dovetailed-shaped slots 118 in slides 112 and set screws 120 are provided for retaining said curved supports 116 in adjusted position and to determine the angular relation of the paths of reciproca# tion of the knife-carrying slides 92. In addition to adjusting the angular relationvof the paths of reciprocation, it inay be desired to tilt the cutting edges of the breast cutting knives 90gin order, for example, that the abutinents lllltniay be under-eut to re `:ive the forwardly extending edge of the breast surface of a heel. To this end the knives are adjustably supported upon the slides 92 by mounting' them upon curved adapter to bereceived Within correspond` plates 122:

ingly `.Curved fdo'vetailed slotsatftlie endsvof y' the slides 92; As shown. in Figs; land 7, f*

the ends of slides 92 are fornied of ytwo parts clamped 'together by screws 12d, which also serve to secure plates 122 in Vadjusted position.r 'The knives 90 arey attached to out- Wardly extending arms upon the plates 122 by ineens of bolts 123`passing `through slots inthe lrnife blades,`as indicated in Fig. 1,

inlordertliat the bottone.v of the cutting edges inay be brought down. close against the upper surface of the cre* vsie-plates 20. l It should be y noted that the curvature of the slot Within which the cuived plate 122 is received iii-ay be aboutk a horizontal asis. substantially coinci? dent withtheplane of the upper surfaces of the crease plates 20 so that the uj'iright edges y of the lrnives 90 niay be tilted about a hori-L zontal axis tocause thein to produce undercut abutrneiits insteadof the verticalabutnients i illustrated in Figy. The operation of these breast-cutting `knives 90 is illustratedl in Fig. 5, from Which it Will be seen that the shoe is positioned in the niachine by means of the crease plates so that the back seam v180 coincides with thenieeting point 32 ofthe reduced'edges 80 of said plates and that said reduced edges are forced firmly into the rand crease 132 of the shoe beneath the overhang ing peripheral portion 134 of the sole.` The breast-cutting knives 90 are forced inwardly K frein the outer edges of the .sole to niake cuts transversely of thesole vand preferably 4the earns `102 are sov arranged that the lknives act successivelyin order that there may be no danger thatL their cutting edges shall be brought' into enf-incarnent with one another.

1n case it is'desired to lit the shoes forthe reception of Louis heels in which the forward, overhanging breast of the heel tapers to a thinedge as at 186 8), it is helpful to provide a short, thick tongue 188 beneathv the flap 106 to actas an abutment and rein-k forcement to aid in holding said overhanging edge'lti' in positionand to prevent its separation from the sole of the shoe. in this case the breast-cutting knives are formed as f Vthe angle of severance of the short, thicli tongue 138 illustrated in Figs. lland 8.

ineddition to inalring the heelbreast receiving cuts in the manner already indicated, n

the heel seat iittingV operation comprises the YAtrimming of the rear end of the sole of the` y shoe to remove surplus material and to bevel it, asvindicated at 146 in Fig. 3, in order that the upper peripheral edge of the heel, such,

'as that shown at 148 in Fig. 8, may be brought into close contact with the upper` 150 of the shoe vwhen the heel is attached, and so that the periphery of the soleV shall not show at this point. This alsoserves to allow the attaching face 152 of the heel 153 to be brought intoV close engagement with the heel seat surface 154 of the sole so that a iirmsupport providedV for the heel byreason of the close contact between the attaching face and-the heel seat of theshoe.

f This trimming operation is effected by distorting the heel seat portion ofthe sole and rotating a knifearound a fixed axis perpen-V dicular to the sole with the. cutting edge of the knife moving in a substantially horizontal 'plane to trimfo surplus material from the peripheryof the heel seat portion ofthe Vsole'by cutting through the distorted edge portion.v VTo this end, a guideway 160 is provided upon the frame of the machine at :the

rear and in this guideway there is mounted for` vertical movement plunger 162 having at its upper end an overhanging arm 164.y A verticaljstud 166 attheouter end ef the overlhanging arm- 164V carries at its lower end a presser member 170 `which is'alongated as shown in the plan view in Fig. 6 yand has a curved cross sectionV as indicated'inFig. 4.`

The stud 166 itself is fixed in the arm 164 and 'serves as a bearing-for al rotatable sleeve 17 2 having a projectingtoe 174 which helps toV support a flat knife blade 180 of substardtiallyY rectangular shape. as illustrated in Fig. 6,

and provided with cutting edges upon thev three exposed sides. Mechanism is provided for lowering the plunger 162 to" bring the vtransmitted through the wooden last 182 to depress said last'pin slightly in order that the distorting action of the presser member may become effective. Thenever thev breast cutting knives have been operated first. has been previously described,V the distorting action of the presser member will not only ele vatethe peripheral portion round the rear ef the-heel seat of the sole but will also elevate the peripheral portions .immediately `to the rear of the breast cut so that there is an abrupt projection into which'the edge of the trimming knife 180 is directed'as it is rotated upon the stud 166,*thus facilitating the entrance of said knife into the leather cf the raised edgeportion of the heel seat ofV the sole. The mechanism is so arranged that a single complete rotation of the trimming knifev 180 is eifected starting at the position illustrated in Fig. 6, after which the mechanism causes a single reverse rotation of the knife as the parts of the machine are brought back into their initial position. Y

To Aeffect the depression of the plunger 162 so as to bring the presser member against the sole of the shoe a sliding bar r184 (Fig. 1)

Vis provided having a stud 186 at its lower end ted resiliently through spring 194 to the plunger-162 and Vhence to the Vstud 166 and presser member 170. An adjustable stop k196 is previdedV to limit the downward movement of the plunger so that the knife .blade will never be broughtinto aplane below the plane of the upper surface of the crease plates. The lower end of the sliding bar 184 is slotted as indicated in dotted lines inFig. 17 so that it surrounds the cam shaft 64 and may be power-actuated by means of'a cam 198 acting againsta roll 199 yupon said bar.

ln order to rotate the knife-carrying sleeve 17 2 a gear connection 200 is provided to which Vmotion be transmitted by means of a rack 202 carried within the over-hanging arm 164 of the plunger and this rack in turn is moved by a pinion 203 carried at the upper end of a vertical shaft 204 mounted within the vertical portion of the plunger 162 and geared-at its lower end to a pinion 206 mounted upon a stub shaftin the frame of the -machine and arranged to be oscllated by means of a segmental gear 208 carried at the upper end of a pivoted arm 210. yThis arm is pivoted at its lower end on the `frame of the machine and is provided with a cam roll 211 resting against a cam 212 on the cam shaft 64. A. spring 214 extending between the arm 210 and the frame of the machine acts to hold the cam'roll against thecam surface and to return the trimming knife to its original position at the termination of the trimming operation. Preferably, the co-ordinationv of theparts is such that this reverse rotation of the knife takes place after the plunger is moved upward again so that the knife is out of contact with the heel seat of the shoe.

. t will be noted from Figs. 1 and 4 that a slip joint 216 is provided in the sleeve 172 carrying the knife blade. This allowsfor a vertical adjustment of the plane of action of the knife blade upon the supporting spindle 166 and, to hold the knife-'carrying sleeve in its. adjusted relation, y,there is provided an adjustable plate 218 secured to the outer end of the overhan'ging arm 164 and projecting inwardly at its lowerend between flanges 220 upon the knife-carrying sleeve 172.

`When the operator wishes to perform the v heel seat fitting operation upon any particular type of shoe he first makes sure that the stop 196 and the adjustable plate 218 are in .proper adjustmentand that the guides and supports for the heel breast knives 90 have beenproperly adjusted to move said knives in the desired path. He then places a lasted shoe upon the-last pin 50 and moves :the end of the shoe into the recess between the crease plates 2O and operates the lever 34 to move said plates forcibly into the rand crease thereby definitely locating the shoe in the machine and supporting the overhanging peripheral edge of the heel, seatportion of the sole.

Aft-er this it i sonly necessaryY for the -operator to depress the pedal 8O to set in motion the power-operated mechanism. This mechanism actuates the breasting knives 90 one after the other to make a transverse cut entering therperipheral edge of tliewsole and eX- tending along the heel breast line so as vt0 form an abutment suchas that illustrated at 104 in Fig. A3. The power--operated mechanism then causes a depression of the plunger 162 forcing the presser member 170 against the central or median part ofthe heel seat of the shoe to distort theheel seat after which the trimming knife is rotated about its verticalwaXis to cut through the raisedperipheral portion of the heel seat o f the sole and to trim it on the bevel146 thereby removing j the surplus material and forming a properly shaped heel seat to receive the attaching-surface of the heel.- At the completion of a single rotation Aof thecam-sh'a-ft 64 the ma-L chine stops and thefoperator is enabled to re-` lease and remove the shoe.
