To all wfiom it may 'cbncern: Be it known that we, ALBERT A. MAGLEOD and LoUIsM. BROW citizens of the' United States; residing at 'Swam'pscott and Beverly;

In'the manufactureof a welt shoe the up per is lasted against {the upstanding lip or rib ofthe innersole at the sides and toe of the shoe and secured temporarily in place by tacks. At the heel theup'per is lasted down upon the heel seat and secured permanently by'tacks. Theupper is then sewed,

together with the'welt, to the lip or rib of the innersole from} the breast edge of the heel seataround' the-periphery of the fore p'a'rtof the, shoe and back to the breast edge of the heel seat. Theupper, welt and innersole connecting'seam is called the inseam and this sewing'operati'on is performed by a special sewing machine called awe lter. In making some yarieties of Welt shoes the welt strip, instead of be severed at the heel breast line at the completion of the welting operation,

subsequently secured around the heel seat of the "shoe, either to provide' a continuation of the welt to! whichthe outsole be attached or to provide a rand between the heel seat and the lifts of the heel. Sincethe up-v per of the shoe has already beenpermanenfly secured to the heel seat by the lasting tacks,-

and innersoles are not usuallyprovided with lips around the heel seat, the; operation of attaching the extension of the-welt'to the heel seat cannot beperformed by the'welter.

It is the general object of this invention as" provide "a machine which will be well adapted for performing the operationof'atis allowed to extendfrom thein seam a ufficient amountso that it may be titlching a welt to the heel seat of a lasted s oe.

The'marg'in of the heel seat'face ofa lasted shoe presents an uneven surface be} cause of the lastingv tacks and folds of the upper; One important feature ofathis in vention consists in meansftefacilitatethe movement of the shoe progressively under the work rest of the welt attaching machine as the attaching operationproceeds. This means may comprise; as shown; a member which engages the heel seat over a considerable'a'rea adjacent to" the line along which the welt is to be attached and which has a'smooth surface'in contact with which the surface of the heel seat may readily slide. In the illustrated embodiment of this invention this means comprises a plate which is adapted to be inserted between the welt andthe heel seatand is located immediatelyin advance of the lineof action'of Y the welt attaching means, said plate being preferably connectedunovxbly to suitable supporting" means. The plate may, as here'- in shown, have a normally depressed position to facilitate the insertion over it of the welt strip projecting 'rearwardly from the inseam, as above" suggested, and the plate may be constructed and arranged to, be moved upwardly to working'position by the shoe asan incident to the operation of positioning'the shoe in. the proper relation to the weltattachingmechanism; I

Another feature of theinvention consists in a' welt inclosing guide, of which theheel seat engaging plate above mentioned, .preferably forms a lower wall. As shown in the drawings, the welt-attaching: means is, a tacker provided with a .rigid work' rest against which the shoe may be pressedfup wardly to receive tacks. In the lower face. of this rest is formedza recess across which. the said engaging plate extends a) confine the welt. An inclosing'guide. for the welt is. important because resistance ofthewelt to being bent edgewise around the curved p01? tion.of the heelis likely to cause the iweltto escape. from the welt guide unless thewelt is substantially surrounded. -Iffthe heel seat engaging plate formsithe lower, wall pr the guide and has a normally depressed. position, the welt guide is normally'open and the welt is readily positioned in the guide by a movement of the shoe laterally of the welt strip; that is, by a substantially horizontal movement of the shoe into position beneath the tacker. This arrangement enables a welt strip having one end secured to the shoe to'be introduced. into the welt guide by the usual and necessary movements ofthe shoe into operative relation to the securing mechanism, and therefore without especial attention from the operator, and saves the loss of time which would be required to thread the welt end through a permanently closed guide.

These and other features of the invention will appear more fully from the following description when read in connection .with the accompanying drawing and will be pointed out in the appended claims.

In the .drawing, v

Figure 1 is a perspective view of an embodiment of my invention;

Fig. 2 is a plan view of the welt guide and edge gage showing a shoe in position for the operation of attaching an extension of the welt about the heel seat thereof; I

Fig. 3 is a side view of the parts shown in Fig. 2, including a sectional view of the top portion of the jack post; and

Fig. 41 illustrates the appearance of the shoe after the completion of the operation of securing the welt end about the heel seat.

Referring to Fig. 1 of the drawings, the reference character 2 indicates the frame of themachine. A driver 4 is mounted to be reciprocated at a slight inclination to the vertical and cooperates with a tack block 6 which reciprocates horizontally from a rearward position in which it receives tacks which are automatically fed to it from a raceway to a position under the driver which passes through the block and forces the tack int'crthe work. A support 8 issecured to the machine frame 2, as shown in Fig. 8, and to thesupport 8 is adjustably fastened by screws and slots at 10 a rest or abutment 12 which is provided with a notch 14; over which the tack block 6 lies when in its forward position and through which the driver operates to insert a tack into the work. By loosening the screws 10, the rest 12 may be adjusted to bring the notch 14: into alinement with the driver. On the under face of the rest 12 and laterally in a line with the notch 14 is a recess or groove 16 which forms a guide for the welt which is to be secured to the work. At the back of the recess 16 is a member 18 which is arranged for adjustment to vary the size of the groove to adapt it to different widths of welting. The members-18 is T-shaped, as shown in Fig. 2, and is held'in adjusted position by a screw and slot adjusting means 19. To the under face of the rest 12 is secured, as by rivets 20, a plate 22 to the forward end of which is movably secured, as by a hinge, at 24 a plate 26 which underlies the groove 16 and preferably conforms to the contour in plan of the forward portion of the rest 12. The right-hand or advance edge of the plate 26 may be upturned, as shown inFig. 3, to facilitate the passage of the work thereunder.

An edge gage 30 is provided which preferably is a steeply inclined, frusto-conical fiber roll, the upper and larger periphery of which contacts with the side of the shoe at a point in very close proximity to the plane of the shoe bottom where the shape of the shoe is such that the edge gage will insure the securing of the welt at a uniform distance from the edge of the last bottom. A handle 32 is provided which may be grasped by the operator by the same hand which holds the shoe in position against the rest 30, and this handle may conveniently be formed as an extension of the pivot upon which the roll 30 is mounted.

The jack for supporting and positioning the shoe relativelyto the welt guiding and attaching means is in most respects similar to that shown in United States Letters Patent No. 919,4:24, granted April 27, 1909, on application of William H. Gulf, and reference may be had to that patentfor details of the mechanism not herein given.

The center about which thejack post swings in its to and fro movements to carry the shoe into and out of position to be operated upon should be in vertical alinement with the driver in order to firmly support the shoe and to effect this a toothed segment 42 which engages a rack 40 is formed on a yoke member 46 havingrearwardly projecta ing arms to which are'pivoted at 4:8 arms of 5 1 against the action of a spring 58, and the jack post may be quickly adjusted vertically to accommodate different heights of last and to quickly adjustthe force with which the shoe will be upheld against the rest 12 by operating a handle 62 to vary the relation of the cam faces 64, 66. By means of the yokes 4:6, 50, it will be apparent that the pivot about which the jack post is'swung is carried rearwardly to a point which is substantially in vertical alinement with the driver and with the heel pin upon which the shoe is spindled when'the shoe is" in position to be operated upon. The jack is prevented from swinging about the supporting post 7 0 by a block 72 mounted on one of the supporting brackets of the jack and engaging a groove 7 1 formedin the jack frame as shown in Fig. 1. I

To prevent'thefcatchingiof the upper between thecrown of the 'last'and the flange at the base of the heel pin, the construction shown in Figs. 1 and?) is providedwliich comprises a collarSO which slips easily upon the last pin 82 and in the periphery of which are pivoted a series of toggles or jointed members 84, the opposite ends of which are similarly pivoted in a'fiangeformeclf on the mid portion of the pin 82 w'hichis seated in theusual manner in the top of the jack post.

The toggles are normally held'in a partially straightened position, as shown in Fig.1, means of a spring 86 acting on a pin 88 which passes through the collar and rides in a vertical slot 90. in the last pin 82. The hole in which the spring 86 is seated is extended upwardly as far as the slot 90 to permit the spring to act upon the pin 88 and to hold the toggle members in the position shown in Fig. 1. WVhen the shoe is presented to the last pin 82, the action of the toggle members as they are bent by pressure of the crown of the last upon the collar 80 is to push the upper away from the last and heel pin so that it cannot be pinched between the crown of the last and the collar 80 and injured when the last is forcibly upheld against the rest by the jack.

The mechanism described in the above paragraph is not claimed herein but is made the subject-matter of a divisional application Serial No. 231,514, filed April 29, 1918.
