Divided and this application filed December 9, 1927.

This invention relates to the art of making shoes, and "particularly concerns apparatus for securing the outsoles to the insoles and associated uppers.

There have been developed, as is illustrated in an application Serial No. 255,209, filed in the United StatesPatent Oflice in the name of Laurence E. Topham on September 21, 1918, automatic machines for stitching; the outsoles of welted shoes to the welts. In such apparatus, ashoe operated upon has within it a last, which is engaged-by a jack, and to this jack movements are imparted to cause the correct presentation of the outsole and welt to stitching mechanism which effects the attachment. In other types of shoe, as those in which the outsoles are nailed, pegged or McKay-sewed to the insole, the mechanism which inserts the fastenings includes an element, customarily in the form of a horn, which must act withinthe shoe, and consequently the last must be removed from the shoe during this operation. Herctofore, so far as I am aware, it has been impossible to apply manufacturing methods of the above-indicated character to these shoes,

because of inability to properly support the work for the operation. An object of my invention is to provide for holding a shoe independently of a last, so that it may be presented effectively to an operating mechanism after the last has been removed and control exercised over the relation between said operating mechanism and the work. To this end. I prefer to grasp the shoe by the outsole, which has been at least temporarily attached to the insole and associated upper, its position having best been gaged with reference to adjacent portions of said upper. While thus held, the interior of the shoe is left entirely free to receive portions of the operating mechanism, and if the worlr is to travel in the operation upon it, this movement may be controlled accurately, so that the stitches or other fastenings may be inserted along a predetermined path.

It is desirable that the relation of the inserted fastenings to the peripheries of the outsole and insole shall be quiteexactly determined, since these fastenings are com- Serial No. 238,849.

monly placed along a previously-formed channel in the outsole, to be concealed by a turned-down channel-flap, and, to insure the continuity of connection between. the o soles, all the fasteninggs should enter the in' sole. On the other hand, the fastenings should not be placed so far into the insole from the edge as to leaveany considerable portion free to curl under the influence of moisture and heat in wear, rendering; the shoe plet may be caused to perform a double func tion'by acting in conjunction with pressure against the opposite face of the sole to hold. the sole for the operation upon it;

The use of a positioning member or templet, as above lIlQlCittGCl, is considered to he an important feature of the present invention, which feature, in. its broader aspect, is not limited to the performing; of operations upon a shoe from which the last has been removed. Furthermore, this positioning memher or templet, together with means for removahly securing it in the proper-position I with relation to a shoe and to aiackupon which the shoe is supported also constitute features of the invention which are notnecessarily limited. to' use in connection with. the performance of operations upon shoes from which the lasts have been removed.

In addition to the features of the invention above referred to, the present invention also consists in the constructions, combinations and arrangements of parts hereinafter described and claimed, V

The several features of the present inven tion will be clearly understood from the following description taken in connection with the accompanying drawings which illustrate.

I have chosen to present my invention in connection with the securing of the outsoles of McKay shoes, though it is to be under-c stoodlthat it may be of utility when applied to different operations upon other portions of shoes of dissimilar types. There appears at A. in the drawings a stitching apparatus, which, as far as its general characteristics are concerned, may correspond to those disclosed in United States Patents No. 1,050,568., Scott, January 14, 1913, and No. 1,177,581, 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 castolf 18 and 'a feed-point 20, all of which co-operate as usual to form successive stitches through the work and advance said work to receive aseries of the stitches. Associated with these elements in the formation of the stitches is a whirl 22 rotatable in the upper extremity of a horn 24, the lower end of whichis arranged to turn in a bearing .26 in a bracket 28 projecting from the front of the casing.

'l he whirl is connected by gearing 30 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 main driv ing mechanism. The workis held down upon the supporting horn for the producion of stitches by a presser-foot 34 vertically movable in the'head upon a spring-actuated bar 36. 'M echanism, a portion of which appears at 38, serves to raise the presser-foot at the termination of each stitch-producing cycle to permit the feed of the worl and joined to this mechanism is an arm 40, to which may be applied force to lift the presser-foot at the end of the stitching'operation, to free the shoe for removal and allow the application able supporting members 42 and44.

of another shoe.- This last connection will later bemore particularly referred to.

Carried upon the base-casing 14 is a jack or work-support B, which is arranged to grasp a shoe by its exterior for submitting it to the action of the operating mechanism, this leaving the interior entirely free for the entrance and movement of the horn. This ack is shown as consisting of two relatively movv The first is preferably formedzintegrally with a short, hollow standard 46 situated below the bearing of the horn and extending in a sub stantially vertical direction. The lower portions of the jack members are U-shaped' in transverse section, and they are curved from the standard 46 outwardly and upwardly, so

that they completely'clear the horn 24 and its mounting, permitting a work-controlling movement of the jack, and also rotation ofthe horn without interference between these two elements] The upper extremity of the member 42 is divided into diverging arms 48, 48, lying substantially horizontal and at their outer ends returninginto close proximity to each other. The associated ack member 44 is pivoted at 50 upon the standard 46, first passing upwardly within the associated member, and then somewhat diverging therefrom, it terminating in a generally horizontally extending socket 52, shown as rectangular in cross-section and open at both ends. This socket is adapted to receive and hold firmly a shank 54 formed upon one end of a templet 56 for positioning the work 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 ex tending downwardly from the templet at the heel-seat-end and being spaced from one another along the longitudinal axis. They are arranged to enter correspondingly spaced openings 300 in the heel-seat-portion of the voutsole 302 of a shoe 304. Rising fromthe opposite face of the templet from the projections 60 is a flange 62, somewhat greater in height than the turned-up flap 306 of the sole to be operated upon and corresponding in contour to the groove 308 of the channel 310 in the'outsole. When the shank 54 is seat-ed in the socket 52, the templet becomes one of opposite members arranged to grasp the upper and lower faces of an outsole and hold it with the attached elements for operations upon it or upon the associated parts.

Mounted upon the ack member and acting with the templet is an opposite pressure member 64. This is shown as arcuate in. form, being curved to embrace the counter portion of the upper 312 ofthe shoe 304 and to present an upper plane surface to the adjacent face ofthe outsolea From the pressure member is an outward and downward extension 66 arranged to move in ways 68 in tremity of which projects within the rear of the socket, where it is normally held by a :spring 78. extending between the arm 44 and the lever beneath its'fulcrum.

To cooperate with the templet in its grasp upon the sole at the opposite or toe-end of the. shoe, the member 42 has fulcrumed at the outer junction. 01 its arms 48, a leverSQ arranged to swing vertically. At the inner side of this lever is a cam-depression 82 (Fig. 4), which is formed between an overhanging upper projection 84 and a lower projection 86, preferably somewhat less sharply curved than the associated projection. A spring 88 acts between the jack member and lever to urge the projection 84 of the latter downwardly. \Vhen the niembers42 and 44 are drawn 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 thelever about its fulcrum and forcing the projection 86 upwardly against the under surface of the sole, which is thereby pressed againstthetemplet. At each side of the sole-.holdingleverSO is shown a gage-lever 90, pivoted upon the upper. outer extremity of the corresponding arm 48, said gage-levers being geared at 92 tov move together QFig. 6). These levers have curved arms arranged to contact with the opposite edges of the outsole ateach side of the toe, and are pressed toward each other by a spring-actuated plunger 94, which contacts with one of them. In their normal position, these lever-arms. are sufficiently close to each other to simultaneously engage the narrowest sole. which may he applied to. the jack, and when this iscarried between them, the uniiform force which they exert in opposite, directions serves to aidthe engagement of the templet-shank with the socket 552 in holding the solo in the correct position to. receive the action of the stitching mechanism. To draw the members 42 and 44 together into. their work-holding relation, a tensionspring Qdeatendsbetween them. They are releasably maintained in;.their work-receiving position by toggle-lever 98, which, when straightened, spaces the members sufficiently to permit the application of a shoe with its, templet to the jack, and, when broken, allows the spring 96 to draw the members together, bringing the toe-end of the sole into cooperation with the clamping lever 80. A spring 100 is provided between the outer extremity of one of the toggle-arms and the member 44, which has the effect of bringing the two. arms into alinement, when the jack members are separated. I prefer to utilize the movement produced by cation of a shoe with its templet to the jack for breaking the toggle. When the lever '42 4 is turned upon its. fulcrum by the contact with its end 76 of the templet-shank 54, a

projection 102 from its side engages the" hooked end of an actuating member 104 mounted within the jack member-'44 andar ranged to slide along and oscillate about a pin 106 set in said member and projecting through a slot in the actuating member. The latter is held normally lowered by a spring 110 connecting it with the member 44. At its lower extremity, it is hooked forcontact with a projection 112 upon the extremity of the adjacent arm of the toggle 98. Then the. lever 7 4 is, turned by the shank 54 striking its end '26, the projection 1 02 rotates, in

a contraclockwise direction 4) lifting the slide 104. This, through its opposite, hooked end, turns the left-hand arm of the toggle clockwise, breaking this and allowing the spring 96. to draw the members 42 and 44 together. In this. movement of the toggle, a cam 114, formed upon the toggle-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 of the jack. This is as illustrated in Fig. 1 of the drawings, Y

The jack, as will later be more fully described, is automatically moved to bring that portion of the sole which is, to be secured into copperation with, the stitching mechanism, this movement, includingrotation of the jack through about 180, degrees, and a reverse roat n to the ini ial. posit ur g th return of the jack to normal, this member 44 is swung upon the member 42, to release the work, and is locked; in this. open relation ready for the reception of the, next shoe to be operated upon. This is accomplished in the following manner The standard 46 is connected by a gimbal joint 116, (Fig. 5.) to a,

wheel 118 (Fig. 2) rotatable upon a vert cal stud 120 mounted in a frame 122, carried by an arm 124 pivoted within the base-casing 14. United to the top. of the stud by a gimbal joint 126, so that it may share in the universal tilting movement of the standard 46, though held against rotation therewith, is a spindle 128, having fixed to its upper extremity within the jack-standard a cam 130. Contacting with this cam is aroll 132 rotatable at the top of a bar 134 pivoted in a recess 136 at the lower end of the jack member 42 adj acent to its pivot 50. The recess and bar are shown as rectangular in section, the bar fitting within the recess to move about its pivot the appli-" against the force exerted by a spring-actuated plunger 1238, yet being held against movement in a lateral direction by contact with the walls of the recess. During the rotation of the ack in the direction of the arrow (Fig. 5) for the operation upon the supported shoe, the roll 132, pressing against the cam-projection, forces the bar away from the recess, so that it slips under the cam in its yield, without affecting the member 44. When, however, the ack is restored to its initial position by reverse rotation, the bar 134 is in contact with the inner surface of the recess, and is heldagainst oscillation. Consequently, the

cam acts to turn the member 44 about its pivot 50, so separating this from the associated member 42 that thetoggle 98 is straightened to lock the jack in its work-receivingposition.

To effect the automatic movement of the jack, some such mechanisms as are shown or described in the application previously mentioned, or perhaps better in application Serial No. 312,366, Topham and Morrill, filed July 21, 1919, may be employed. Here it will only be stated briefly that the jack-arm 124 is pivoted at for vertical movement upon a carrier 142 (Fig. 2). This is, in turn, pivoted at 144 in a second carrier 146 to swing transversely of the machine, while the carrier 146 is pivoted at 148 to move from front to rear of the machine. A. spring 150 between j a rearward extension of the arm 124 and the carrier 142 exerts its force to hold the jacked shoe up into engagement with the stitching mechanism. To feed the work past this mechanism for the operation upon it, a cam 152 of suitable contour (Figs; 1 and3), fixed upon a driving shaft 154 journaled vertically in the base-casing 14, acts through connections 156 to the member 42 of the jack to impart to the work movement transversely of the front of the machine, swinging the jack upon its mounting on the frame 122. At the same time, the curvature in the periphery of the shoe is allowed for by rotating the jack through connections 158 between another cam on the'shaft 154 and the wheel 118. These two component movements permit a sole of any peripheral contour to be presented to the stitching mechanism. To compensate for departures of the sole from a plane surface because of its longitudinal and transverse curvatures, other cams, through connections. 160 and 162, respectively tip the jack transversely of the machine upon the pivots 144, or from front to rear thereof on the pivot .148. .All this is in no respect different from the structures of the previously-mentioned applications; but in the present instance it is not desired, during the return movementof 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 sufiiciently to free it from the horn.

Consequently, the actuating member 164 (Fig. 2), which, in the Topham and Morrill machines engages a hook upon a link 166 con- 7 nected to the jack to thrust it out, in the present organization acts upon the hook to raise:

the link, and through it the ack Simultaneously, in the present apparatus, a surface 168 of the member 164 contacts with a rod to the arm 40 of the mechanism for controlling the presser-foot. As a result ofthis, when the jack is'lifted by the action of the member 164 upon the link 166, the'contact;

of the surface 168 with the rod so moves the arm 40 that'the presserfoot is raised from.

the operating position to free the work, and there held until the beginning of the succeeding operation. r

In machines of the character of that herein describedflt has been customary for the operator to turn the horn manually about a vertical axis to most effectively present its work-en a in eXtremit to avoid inter= ference with the upper of the shoe and to lessen resistance to movement of the insole over it. In the present apparatus, this rotation of the horn is accomplished automatically, there beingsecured to the base of the horn, within its bearing (Figs. 2 and 3), a sprocket-wheel 176 connected by a chain 178 to a sprocket 180 fast upon a vertical shaft 182 journal ed in the casing 14. Fixed to this shaft 182 is a pinion 184 meshing with a gearsegment'186 upon a lever 188 fulcrumed in the casing and movable horizontally. This lever is joined by a link 190 to a lever 192, also fulcrumed within the casing and having a roll engaging a cam 194 upon the shaft 154. i

The form of this cam is such as to impart to the horn, through the chain of connecting elements, its rotation during the operation upon the shoe and reverse rotation in the desired timing, the total angular movement in each direction beingsubstantially 860 degrees.

In preparing the shoe for the operation of themachine the upper 312 of the shoe 304 which is to have its outsole attached is lasted over the insole 314 in any convenient manner. The outsole 302, in which are formed the locating openings 300, is laid upon the shoebottom, positioned in symmetrical relation to machine being actuated to drive" one ormore staples through the channel or other portion of the outsole into the insole. 7 Such machines are well known, and will not here be described. To position the outsole with. relathe nozzle'of which is indicated at 200 in Figs. 7, 8, and 9 of the drawings, thethe edge of the insole and its surrounding HP-ZZIZO' tion to the insole for this operation, gaging mechanism is shown associated with the tacking machine. This may include a presserfoot 202 forked to engage the surface of the outsole at each side of the insole and being situated above a rest 208, which may be raised and lowered by treadle mechanism, which is not illustrated. The presser-foot is guided upon a vertical spindle 204 fixed in a support 206 carried upon the frame of'the tacking machine. Mounted in the lower end o'f'the spindle is a pin 210 of such diameter that it will fit snugly one of the locating openings 300 'in the outsole, and also a corresponding opening 316 in the insole, it being movable in a bore in the spindle and forced yieldingly down between the arms of the presser-foot by a spring 212 situated within a recess in the spindle. Pivoted upon the support 206,-at opposite sides of the spindle, are pairs of levers 21a,

21 1 and 216, 2 16, the converging upper ends of which are drawn by springs 218 against oppositely inclined surfaces of cams 220 and 222. These cams are movable vertically upon the spindle 204, :the cam 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 cam and the support 206 is interposed a spring 228. The levers are ofsuch lengths that when the upper over the edge of the insole is engaged by the inturned lower ends of the pair 214, 214, the corresponding-portions of the pair .216, 216 are in contact with the edge of the outsole. A gage member230, 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 of the edge of. the sole from the nozzle. In 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 230, and the rest raised by its treadle to force the Work between the pairs of arms 21 1 and 216. The outsole contactswith 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 pairs21 l and216 toward each other at the'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 intoalinement with the pin 210, which will enterthe openings, more positively determining the relation between *the shoe-elements. The springs 22 1 and 226, by their yield, permit independent action of thecams 220: and 224 to adapt the mechanism'to operate properly upon uppers and associated soles of differentwidths. The spring 228 allows for continued upward travel of the work after engagement of the levers has been effected, When the outsole, in its movement atter the gaging action, comes in contact with the nozzle 200,-this trips the tacking mechanism, and the attachment of theoutso'le to-t ne shoebottom at this point inits true relation iseffected. At the toe .of the shoe, the operation is similar to that just described, save here there are no locatingopenings for the 2&0

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 templetuponit, locating :the two in the correct relation by the entrance of the templet pins 60 into the openings 800, and introduces the [projection 54 into the socket 52 of the jack (Fig. the shoe passing beneath the sewing mechanism, from which the jack has been lowered at the end of the previous operation, and the up.- perextremity of the horn entering the opening in the upper. As the shank contacts with the curved end ofthe lever 57 1, the docking mechanism, which holds thejack inthe' workreceiving position, is tripped, and the-.pressure-lever is brought into contact with the toe-endof the outsole to urge iitztoward the templet'by its pressure againstzthe opposite face. Asthisis occurring, lthemember 64: is being raised by the lever :74 againstthe under hereof the sole at the heel ofthe shoe. Consequently,-the work is held between the templet as an upper clampingmember ofrthe jack, and the elements 80 and 64 as lower clamping .members at both extremities, so that it is grasped positively for :the'action upon it. The operator mayjnow depress the jack to bring the work into co-operationvvith the horn, :this unlocking the member 164, which assumes its normal position. After turning'the jack to bring the starting'point for the stitching opposite the operatingfmech- V anismgthe machine is started by:the depressionof a treadle, this alsolowering thepress er foot against the, sole. Thetemplet-flange 62, contacting with the side ofzthe presserfoot at 58, furnishesa fulcrum, sothat, under the guidance of the templet, the jackis moved by the cam mechanismwaliongea predetermined path to present:the .work to the operating mechanismfor the insertion: Ofrthe Th1s automatic action fastening stitches. continues until thelopposite side-of theshoe is reached, McKay stitching erdina-rilyzbeing applied from near the breast-line at one sid'e of theshoe to the corresponding-point at: the
