outsoles oi welted shoesto the welts. In
such apparatus, a shoe .Operated upon has Within it a last-,which isengaged by a jack, and to this jack movements are imparted to cause the' correct' presentation' of the outsole and welt to stitching mechanism lwhich eects Y the attachment. In other typesof shoes, as
those in which the outsoles are nailed, pegged yor-McKay-sewed to the Insole, the mechanism which i'nsertsthe asteningsincludes an element, customarily in the form of a horn,
Y which must actv within the shoe, and consequently the last must be Aremoved from the shoe during this operation. AVHeretofore, so 'far as I am aware, it has heen impossible to apply manufacturing methods foi the above-indicated character tothese shoes, because ol" inability to properly support-the u* fior the operation. An object of my invention is to' provide for holding a sho-inue-` pendently of a last, so that it may be presented eil'ectively to an operating mechanism and control exercised ov'erthe relation between said operating mechanism and the work. vTo this end, l prefer to grasp the shoe by the outsole, -whichhasbeen at least temporarily attached to the insole and associated upper its position having best been gaged with reference to adjacent'portions Offsaid upper.

I have chosen to present my invention in lconnection with the securing of the outsoles of hIcKay shoes, though it is to'be understood that it may be of utility when applied to different operationsupon other portions of shoesof dissimilar types. There appears atA in the drawings a stitching apparatus, Which, as far as its general characteristics arevconceriied,`m'ay correspond to those disclosed in United States Patents No.1,050,568, .Scotndanuary 14, 1913, and No. 1,177,531, Meyer, March 28, 1916. Ahead 10 is carried by a bracket 12 rising from a base-casing 14. Mounted `to move upon the head is actuating mechanism for a needle-bar 16, a cast-oft V18 and a feed-point 20, all of which co-oper ate as vusual to form successive stitches through the work and advance said worlr to receive a` series of the stitches. Associated fWith these elements in the formation of the stitches yis a whirl 22 rotatable in the upper extremity off a horn 24, the lower end of which is arranged to turn in a bearing 26 in a bracketi28 projecting from the front ofthe casing. The whirl is connected by gearing l30 contained in the base of the horn and brackets 28 and'12 to gearing 32 located in the head of the stitcher and thereby to the lmain driving mechanism. The work is held down'upon the supporting horn for the production ofstitches. by a presser-foot 34 vertically movable inthehead upon a spring-V actuated bar 36. Mechanism, a portion Vof which appears at 38, serves to: raise the-V `presserfoot at the 'termination of each .stitch-producing cycle to. permit the feed of the work, andk joined tol this'mechanism is an armv 40,.to vwhich may be applied force I to lift vthe presser-foot jat the end of the stitching operation, to free the shoe for rej mova'ljandallow the application of another shoe. AThis-last'connection will laterV be Y more particularly referred to.
Carried upon the base-casing V14 is ajack or worksupport B, which is arranged to grasp a shoe by'its exterior forV submitting -it kto the action of the'operating mechanism., this `leavingthe interior entirely free for the entrance' and movement of the horn. This jack is shown as consisting of two relatively movablesupporting members 42 and 44. The' first is preferably formed integrally Y With a short, hollow standard 46 situated below the 'bearing of the horn and extending in a substantially vertical direction. The lower i -portions of4 the jack Vmembers are Ushaped in transverse; section, and'they are curved `.from the standard 46 outwardly and upwardly,;. so' that they completely clear.' vthe horn 24 and its mounting, permitting a 4into divergingarms 48, 48,. lying substantially'horiontal and at their outer .ends returning into close proximity to each other. rhe associated acl; member 44 is pivoted at 50 upon the standard 46, first passing upwardly within the associated membenand then somewhat diverging therefrom, it `ter minating in a generally horizontally extending socket 52, shown as krectangular Vin crosssectionv and open at both endsjl This socket is adapted to lreceive and hold firmly shank 54 formed `upon one end of atemplet 56 for positioning the yworl; with relation to the stitching mechanism, as by contact with the side of the presser-foot'at 58. The templet has locating projections 60, of which two are illustrated (Fig. 6) these extending downwardly from the templet at the heel-'seat-end and being spaced from one another along the longitudinal aXis. They are arranged tojen'-A ter correspondingly Yspaced openings 300 in erated upon and corresponding in contour'v to the groove 308 -of theV channel .310 in the outsole. When the shank 54 is seated in the soclret 52, the templet becomes one of oppo-y site members arrangedto grasp the upper and 'lower faces of anoutsole and hold it with the attached elements for operationsk i upon it or upon the associated parts.
Mounted upon the :j acl; member 44 and acting lwith the teinplet is anopposite pressurel member 64. rlhis is shown as arcuate inform,
being curved to embrace the counter-portion Aof the upper 312 of the shoe 304 -and to present an upper plane surface to the adjacent face of theA outsole. k1l" rom the pressure member is an outward and downward extension 66 ar.- ranged to movein ways 63 in the jaclr member 44. These waysgincline upwardly toward the companion jack member 42, so .that as lthe pressure member is raised,:itmay be introduced vinto thefcrease beneath the outsole. Formed npon the outer face of the portion 66 is a rack 70, with which Vmeshes a gear-segment 72 upon a lever 7 4 fulcrnmed upon the jack member 44 just beneath the, socket. The f upper portion of this lever consists of a curved arm 6, the extremity of which projects within the rear of the socket, where it is normally held by a spring 78 extending between the ari; 44 and the ,lever beneath its fulcrum. j j j To co-operate with the templet in its grasp upon thesole at the opposite or toe-end of the shoe, the'member 42 has, fulcrumed at the outer junction of its arms 48, a lever ranged to swing vertically. At the inner side of this lever is a cam-depression 82y (Fig. 4), which is formed between an overhanging upper projection S4 and a lower projection 86, preferably somewhat less sharply curved than yhe associated projection. A spring 88 acts between the jack member and lever to urge the projection 84 of the latter downwardly. TWhen the members 42 and 44 are together to clamp the shoe upon the jack, the forward edge of the outsole is thrust against the depression 82, the approach being indicated in dotted lines in Fig. 4, and rides up the projection 84, thus swinging the lever about its ulcrum and forcing the projection 86 upwardly against the under surface of the sole, Vwhich is thereby pressed Vagainst :the templet.' llt eachs'ide of the sole-holding lever 80 is shown a gage-lever 90, pivoted upon the upper, outer extremity oit the corresponding arm 48, said gage-levers being geared at 92 to move together @l G) Vl`liese levers have curved arms arranged to Contact with the opposite edges of the outsole at each side of the toe, and are pressed toward each other by a spring-actuated plunger 94, which contacts with one oi them. ln their normal position, these lever-arms are sufficiently close to each other to simultaneously member. The latter is held normally loi.
engage the narrowest sole-which may be applied to the jack, and when this is carried between them, thev uniform torce which they exert in opposite directions serves to aid the enga-gement oi the templet-shank with the socket 52 in holding the sole in the correct position to receive the action ofthev stitching mechanism. i 1
To draw the members 42 and 44 together into their work-holding relation, tensione.
spring 96 extends between them. They are releasably maintainedl in their work-receiving position by a toggle-lever 9S, which, when straightened, spaces the members sur'iiciently .to permit the application of a shoe with its templet Yto the jack, and, when broken, allows the spring 96 to draw the members together, bringing the toe-end of the sole into co-operationwith the clamping lever 80. Aspiring 100 is -providedbetween the outer extremity of one of the toggle-arms and the member 44, which has the effect or" bringing thetwo arms into alinement whenthe ack members are separated. l prefer to utilize the movement produced by the applicationv of a shoe with its templet to the jack for breaking the toggle. l/Vhen'the lever 'l' 4 is turnedupon its ulcrum ,by the contact with its end ,7G oi' the templetshank 54, a projection 102 from its` side engages the hooked end oi' an actuating member 104 mounted within the jack member 44 ,and arranged'to slide along and oscillateV about a pin 106 set in said member andprojecting through a. slot 10S in the actuating yered vand 44 together. toggle, a cam 114, iormedu'pon the toggleby a spring 110 connecting it with the memA ber 44. At its lower extremity, it is hooked for Contact with a projection 112 upon the extremity of the adjacent arm of the toggle 98. When the lever 7 4 is turned by the shank 54 striking itsend 76, the projection 102iotates in a contra-clockwise direction (F ig. 4), lifting the slide 104. rllhis, through its opposite hooked end, turns the lett-handv arm of the toggle clockwise, breaking this and allowing the spring 00 to draw the members 42 In thismovement ot the arm adjacent to the projection 112, contacts with the slide 104 to disengage the lower hook from the projection, thus permitting the spring 110 to lower the slide into position for the succeeding operation ofthe jack.y `rlhis is as illustrated in Fig. 1 of the drawings.
The jack, as will later be more fully described, is automatically movedv to bring that `portion oi the sole which is to be secured into cooperation vwth the stitching mechanism, this movement through about 180 degrees, and a `reverse roation to the ii al position. I During this ren ofthe jack to normal, the member 44 is s tang upon .the member 42'to releaseV the work, and is locked in this open'relation ready tor the j be operated upon. This is vvaccomplished in the following manner: .The standard 46 is connected ly gimbal joint 116 (Fig. 5) to fel 118 (Fig. 2) rotatable upon a vertical stud 120 mounted in, a trame 122 carried f I bv an arm 124 nivoted within the base-casino v l c:

reception et the nent shoe to tilting movement of the standard 46,'though held against rotation therewith, is a `sp 128 havin@v fixed to its' u ver extremity within the jack-standard a cam 130.` Contacting with this cam is a roll 132 rotatable the topY of a bar 134 piyoted in a recess 136 at theV lower end of the 'ackmember 42 adiacentto .L l f 11 1 J' i its pivot`50. lne recess and oar are snown as rectangular in section, the bar fitting within the recess tomove about itsv pivot against t ie Jforce exerted by a spring-actuated plun ger 138, yet being the walls of the recess. lhiring the rotation of the jack in the directon of the arrow 5) for the operation upon the supported shoe,
the roll 132, pressing against the camfprojec-. ,f
tion, 4forces the bar away trom the recess.y so
that it slips under the cam in its yield, with- Yor-.t affecting the member 44. y lllhen, however, the jack is restoredto its initial p :sil
tion by reverse rotation, the bar 134 is in contact-with the inner'suriiace of the recess, and kis held oscillation. Consequentlv', the

To effect the automatic movement oi the jack, some such mechanisms as are shown or described inthe application previously mentioned, or perhaps better' in application 'lerial No. 312,366, Topham and Morrill, filed July 21, 1919, may be employed. Here it will onlyk be stated brietly that the jack-arm 124 is pivoted at for vertical movement upon a carrier 142 (Fig. 2). rhis is, in turn, pivoted at 144 in a second carrier 146 to swing transversely of the machine, lWhile the carrier 146 is pivoted at 148 to move from front to rear of the machine. A spring 150 between a rearward extension of the arm 124 and the carrier 142 exerts its force to hold the ached shoe up into engagement with the stitching mechanism. To feed the Work past this mechanism for the operation upon it, a cam 152 oi suitable contour (Figs. 1 and 3), fixed upon a driving shaft 154 ournaled ver-v tically in the base-casing 14, acts through connections 156 to the member 42 of the jaclr to impart to the Work movement transversely of the front oi the machine, swinging the jack upon 'its mounting on the traine 122. At the same time, the curvature in 'the periphery or' the shoe is allowed for by rotating the jack through connections 158 between ann other vcam on the shaft 154 and the Wheel 118. These two component movements permit a sole of any peripheral contour to be presented `Vto the stitching mechanism. lo compenate for. departures of the sole from a plane sur- 'ace because of its longitudinal and transverse curvatures, other cams, through connections 160y and v162, respectively tip the jacl; transversely of the machine upon the pivots 144, or from front to rear thereof on the pivot 148. All this is Vin nofrespect different from vthe structures of the previously-mentioned .apphcations; but in the present instance it 4is not desired, during the return movement oit the jack to its initial position after the operation upon the shoe, to carry it outward from the operating mechanism, but merely to raise it sutliciently to free it from the horn. Consequently, the actuating member r164 (Fig. 2) Which,in the 'llopham and lllorrill niachines engages a hook upon a'linlr 166 connected to the jack to thrust it out,- in the pfesent organization acts-upon the hoolr to e the link, and through it the ack. Simultaneously, in the Vpresent apparatus, surface168 of the meinberc164 contactsivith a rod v170 arranged to slide vertically the top of the casing 14 and normally loiveredby a spring 172. This rod connected by a linlr 174 toV the arm 40 of 'the mechanism for controlling the presser-foot. [is a result et this, when the jach is liftedby the action `ot the member 164 upon the link 166, the Contact of the surface 168 Withthe rod so moves the Varm40 lthat the presseroot is raised Yfrom' Ylli imanes the operating position tofree the Work, and 'there held until the beginning of the succeeding operation. i
ln machines of the character ofthat herein described, it has been customary for theoperator to tui", the horn manually about a vertical axis to most eflectively present its Work- 186 upon a lever 188 tullcrumed in the casing and movable horizontally. rlhis lever is ed v a link 190 to a lever 192 also Ltull @ruined Within the casing and having a roll en aging a kcam 194 upona shaft 154. rllhe form oat this cam is such as to impart to the horn, thro-ugh the chain of connecting elements, its rotation during the operation upon the shoe and reverse rotation in the desired t' ning, the total angular movement in each d rection bein.^l substantially 360 degrees.
.ln carrying out my improved method, the
upper 812 of the shoe 804 which is to have its 'i outsole attached is'lasted over theinsole 314 in Yany convenient manner. The outsole 302,
.vhich are `termed the locating openings SL00, is laid. upon the shoe-bottom,,positioned in symmetrical relation to the edge of the insole and its surrounding. upper materiahand is then temporarily .secured in place. Vrllhis preliminary attachment may conveniently' be fetlected by a stapletacking machine, the nozble et Which is indicated at 200 in Figs?, 8
and 9 oi the nraivings, the machine being actuated drive one or more'staples through the channel or other portion of the outsole into the insole. VSuch machines are Well lnovfn a1 l fil tl b l 'b l T' .il 1, .1o. v1.1 no ieie e oescri ec. ko position the outsole with relation to the 1niio sole tor this operation, gaging mechanism is shoivn associated With the tacking machine. This may include presser-toot 202fforlred Yto engaee'the surface of the .outsole at each side: oi. he insole and being situated above a rest 208, which may be raised and lowered by treadle mechanism, ivhich is not illustrated. The presser-toot guided upon a vertical spindle 204 iirzedin support 206 carried the trame of the taclring machine. cunted in the loiver end of thespindle isa pin 210 of such diameter that it rWill lit snugly of the locating openings 300 in the outsolo, and also a corresponding lopening 316 in the insole, it being movable in a bore in the;
iis
flo
ed upon the support 206, at opposite sides of the spindle, are pairs of levers 214, 211l'a'nd 216, 216 the converging upper ends of which are drawn by springs 218 against oppositely inclined surfaces of cams 220 and 222. rlhese cams are movable vertically'upon tne spindle 204, the cani 220 being yieldably mounted upon the top of the presser-foot by springs 224, while the cam 222 is similarly supported upon its companion by a spring 226. Between the upper cani. andthe support 206 is interposed a spring 228. such lengths that when the upperover the of the insole is by the inturned lower ends of the pair 214, 214, lthe correspending portions or Lne paii216, 216 are in contact with the edge of the outsole. A gage member 230, extending substantially parallel to the nozzle 200 at the opposite side from the presser-foot and with its lower end engaging the shoe-upper, determines the distance ofthe edge of the sole from the nozzle. 1n attaching the heel-portion of a sole, the last 320 within the shoe is placed upon the rest 208 with the counter-portion of the shoe against the gage 280, and the rest raised by its treadle to force the work between the pairs of arms 214i and 216'. The outsole contacts with the presser-foot, which is lifted by the movement, at the same time raising the cams 220 and 222 and causing'their inclined faces to swing the levers of the pairs 214 and 216 toward each other atthe same rate. Their contact with the upper and the outsole respectively, moves these laterally until they are symmetrically located. At this time, the'openings 300 and 316 in the outsole and insole respectively may be brought into alinement with the pin 210,l which will enter the openings, more positively determining the relation between the shoe-elements. The springs 224 and' 226, by their yield, permit independent action of the cams 220 and 22e to adapt the mechanism to operate properly upon uppers and associated soles of different widths. The spring 228 allowsy for continued upward travel of the work after engagementof the levers has been effected. When the outsole, in its movement after the gaging action, comes in contact with the nozzle 200, this trips the tackmechanism, and the attachment of the outsole to the shoe-bottom. at this point in its true relation is effected. At the toe of the shoe, the operation is similar to that just'described, save here there arene locating openings for the pin 210 to enter, and this. pin is permitted by the spring 212 to yield, the levers producing all the positioning action.
The sole being thus temporarily held by the staples in the exact position in which it is to be finally secured, the last is removed, and the operator places' the templet upon it, locating the two in the correct relation by the entrance of the templet-pins into the 1 openings 300, and introduces the projection rEhe levers are of 54C into the socket 52 ofthe jack (Fig. 4), lthe shoe passing beneath the sewing mechanism, from which the jack has been lowered at the end ofthe Vprevious operation, and the upper e? emity of y the horn entering the opening'in the upper. As the shank contacts with the curved end of the lever 74, the lockmechanism, which holds the i ack in the work-receiving position, is tripped, and the pressuredever 8O is brought into contact withr the toe-end of the outsole to urge it toward Vthetemplet by its pressure against the op-` posite face. As this is occurring, the member 64 is being raised by the lever'against the under face of the sole at the heel of the shoe. `Consequently, the work is held betweenthe templet as an upper clampingmember of thejack, and the elements and 64 as lower clamping members at both extremities, so that it is grasped positively for the action,Y upon it. The operator may now depress the jack to bring the work into co-operation with the horn, this unlocking the member 161i, which assumes its normal position. After turning the ack to bring the starting point for the stitching opposite thel operating mechanism, kthe machine is started by the depression of a treadle,this alsolowering the presser-foot against the sole. The tem. piet-flange 62, contacting with the side lof the presser-foot 4at 58. furnishes a fulcrum.l so that, under the guidance of the templet, the jack is moved by the cam mechanismv along a predetermined path to present the work to the operating mechanism for the insertion of the yfastening stitches. This automatic action continues until the opposite side of the shoe is reached, McKay stitchingY ordinarily being applied from near the breast-line at one side of the shoe to the corresponding point at the opposite side. At this latter point, the jack is lowered by the controlling mechanism, the presser-foot raised, and reverse rotation of the jack takes place to 'restore it to its initial position. During this time, the action of the cam 130r separates the members 44 and 42 of the jack to release the shoe and lock the parts in po? sition to receive the succeeding piece of work.
