MACHINE FOR OPERATING ON SHOE-WELTS.-

Patented Oct. 9, 1917.

Original application filed November 29, 1912, Serial No. 734,095. Divided and this application filed January 22, 1916. Serial masses.

To all whom it may concern:

Be it known that I, ERASTUS E. WINKLEY, a citizen of the United States. residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Machines for Operating on Shoe-Welts; and I-do hereby declare the following to be a full," clear, and exact description of the invention, such 'as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to machines for preparing welted unsoled shoes for the sole laying operation. The operations required on the shoe at this time include the leveling or butting of the welt ends and the securing of the butted Welt ends to the insole, usually by tacks. The present invention relates particularly to mechanisms for performing the welt butting operation, and to welt butting mechanisms of the general type illustrated in my prior Letters Patent of the United States No. 1,029,837, dated June 18, 1912. The present application is a division of my pending application Serial No. 734,095, filed November 29, 1912, which shows a machine that both butts the welt ends and secures the ends to the insole by means of tacks. The claims of this parent case, however, are directed to the tacking mechanism, while the present application is concerned with the welt butting mechanism. V

One object of the present invention is to simplify and improve the type of welt butting mechanism used in my prior machine to enable it to operate at a greater speed than has heretofore been practicable, while at the same time performing the desired opera tions in a more eflicient manner and with less expenditure of power. It is a further object of the invention to devise a mechanism of this type which will be capable of operating on all sizes and styles of shoes without preliminary adjustment, and to simply and improve the construction and operation of the devices for positioning and supporting the shoe for the welt butting operation.

With these and other objects in view, the invention resides in certain devices, combinations and arrangements of parts, as hereinafter described, possessing advant g s hich will be Obvious to those skilled in this art, and the novel features of which will be pointed out in the appended claims.

The various features of the invention will be readily understood from the following description, reference being'made to the ac-. companying drawings, which illustrate the preferred embodimentof the invention, and in which v Figure l is a, front elevation showing the welt butting instrumentalities of the machine shown in my application above designated, certain parts of the'machine both above and below these instrumentalities being omitted;

Fig. 2 is a rear elevation of the parts illustrated in Fig. 1;

Fig. 3 is a side elevation of the parts shown in Figs. 1 and 2;

Fig. 4 is a cross sectional view, partly in elevation, on the line 4+4, Fig. 3; v

Fig. 5 is a sectional view on the line 55, Fig. 3, certain parts, however, being shown in plan;

Fig. 6 is a vertical, sectional view on the line 6-6, Fig. 5; c

Fig. 7 is a detailed plan view of the welt rests showing them in the proper relationship to a shoe for the purposes of the welt butting operation;

Fig. 8 is a detail view in front elevation and on a large scale of certain parts of the Welt butting mechanism;

' Fig. 9 is a perspective view, partly in section, of the heel. portion of a welted shoe ready for the welt butting operation to be performed on it; and Fig. 10 is a cross sectional view of a shoe with the welt rests of the machine supporting the ends of the Welt in readiness for the butting operation to be performed.

The illustrated embodiment of the invention shows a machine adapted to butt both ends of the welt at the same time, and there is provided, therefore, a pair of welt rests 1 and 2, and a pair of Welt cutters 3 and 4. The rest 1 and cutter 3, are carried by a head 5 which is mountedat the right of the machine to swing in a horizontal plane on a vertical pin 6 (Fig. 5) carried by a horizontal plate 7 (Fig. 1) bolted to the top of column8. The rest 2 and a cutter 4 are also mounted in "a head 9 which is pivotally mounted at the left of the machine on a vertical pin 10 (Fig. 5) carried by the plate 7. The heads 5 and 9 are mounted for simultaneous movement toward each other in order to position the rests beneath the loose ends of the welt at the opposite sides of a welted unsoled shoe and for simultaneous separating movement to permit the unobstructed removal and insertion of the shoe out of and into operative position between the heads. To this end the head 5 carries a segment 11 which is engaged by a segment 12 (Fig; 3) formed on the vertical arm of a bell crank lever 13 pivoted on a horizontal pin 14 carried by a plate 15 rising from the right side of the plate 7 (see Fig. The horizontal arm of the bell crank lever 13 is pivotally connected to a vertical rod 16 (Fig. 3), connected in turn to one end of a bar 17 (Figs. 1 and 2) carried upon the upper end of a vertical rod 18 which is connected at its lower end with a treadle 19 pivotally mounted on the base of the column 8. The bar 17 carries at its other end a second vertical rod 20 (Fig. 2) which is pivotally connected to the horizontal arm of a bell crank lever 21 pivoted on a plate 22 rising from the left side of the plate 7. The vertical arm of the bell crank lever 21 has formed thereon a segment 23 which meshes with a segment 24 carried on the head 9. To hold the heads 5 and 9 normally separated the treadle 19 is connected to the column 8 by a coiled spring 25 (Fig. 2). With this construction a depression of the treadle causes the heads 5 and 9 to close and the welt rests l and 2 to engage in the welt crease and thus grip and hold a shoe in position between the heads.

In order to permit the ready removal, insertion and adjustment of the cutters 3 and 4 the shank of each of the cutters is mounted in a clamp 26 (Figs. 3 and 6) formed by a split cutter block 27. The cutter block 27 is adjustable mounted in an inclined guideway 28 (Fig. 8) formed in a carrier 29. The members of the cutting block are moved to clamp the shank of the cutter, and the block is held in adjusted position on the carrier, by a clamping screw 30 having a shank which passes through a slot formed in the block 27 and is threaded into the carrier and has a head which is held within a recess formed for its reception in the front member of the block 27. Each of the welt rests 1 and 2 is provided with a body portion 31 (Figs. 6 and 7) dovetailed into the heads and secured therein by a screw 32. These rests each comprise a guard 33 (Fig. 7) arranged to extend in a horizontal plane beneath the loose ends of the welt over the marginal portion of the heel seat of the shoe, and an inclined wing 34 having its lateral edge arranged to engage the stitches of the inseam in the welt crease and its upper face roughened to hold the welt.

In order to butt the ends of the welt the cutters are first lowered from the position of Fig. 6 until their cutting edges engage the upper surface of that portion of the weltsupported by the inclined wings 34 of the welt rests, and are then actuated rearwardly in the plane of the guards 33. This operation produces the desired bevel on the welt ends. With this construction the edge indicated at 35 7) at the line of juncture between the wing 34 and guard 33, acts as a blade cooperating with the cutter in shearing the waste piece from the welt.

Advantage is taken of the well defined edge 35 between the roughened wing 34 and the smooth guard 33 to aid the operative in positioning the shoe for the welt butting operation. shoe may be provided with mark 36 (Fig. 7) at some time before the shoe is brought to the machine, to indicate the proper line To this end the insole of the of termination. of the butted ends of the.

Welt. By registering this mark with the edges 35 the proper position of the shoe relatively to the welt butting instrumentalities is insured without the use of gages and the judgment of the operative is not depended upon.

In order to lower the cutters into their operating plane the rear end of the carriers for the cutters 3 and 4 are secured to pivot pins 38 and 39 (Figs. 5 and 6) journaled in lugs 40 and 41 carried respectively by horizontal slides 42 and 43, These slides are mounted to slide on the heads 5 and 9 beneath gibs 44 secured to the heads. To raise and lower the carriers 29 about their pivots 38 and 39 each of the carriers is provided at its forward end with a guideway. 45 (Figs. 3 and 6) which slidably embraces a square sleeve 46 loosely mounted on a horizontal rod 47 the opposite ends of which are secured to oblong blocks 48 (Fig. 3) mounted to slide in vertical slots 49 formed in the vertical side plates 15 and 22. The sleeves 46 are held from movement longitudinally of the rod 47 by being each interposed bctween a boss having connected. thereto a bearing plate 50 (Fig. 5) arranged to slide in a slot on the adjacent vertical plate, and a central sleeve 51 on the rod 47. The sleeve 51 is provided with a pair of arms 52 pivoted on a floating rod 53 (Fig. supported by a yoke frame 54 (Fig. 1) which is pivoted on a horizontal rod 55 carried by the vertical plates 15 and 22. The rod 53 also loosely carries the forward ends of a pair of links 56 which are pivoted at their rear ends at the opposite sides of a yoke frame 57 (Figs. 3 and 4) pivotally mounted on a horizontal. rod 58 carried by the plates 15 and 22. One of the arms of the frame 57 carries a roll 59 which engages a peripheral groove 60 (Fig. 3) formed in a cam cyl nder 61 on a shaft 62 journaled at its front end in a bearing 63 (Fig. 3) and at its rear end in a bearing carried by the back late 65 rising from the plate 7. From the above description it will be seen that the forward end of the welt butting cutter carriers 29 are hung, by their guideways 45, from a pivotal link connection in the form of a toggle, the upper arm of which is formed by the yoke frame 54 and the lower arm of which is formed by the sleeve 51 and its arms 52. The floatin rod 53 forms the knuckle of the toggle an powervis ap plied thereto by the cam grooves 60,- through. the yoke frame 57 and links 56, to make and break the toggle. When the links 56 are drawn rearwardly by the cam the toggle is broken, as shown in Fig. 3, the cutter carriers 29 are raised about their pivots 38 and 39, and the cutters are held above the welt rests. This is the location of the cutter carriers while the shoe isbeing positioned. On starting the machine the cam moves the links 56 forward thus straightening the toggle and lowering the cutters to welt butting position.

After the cutters are low red into their operating plane they are actuated rearwardly to butt the welt. To this end the slides 42 and 43 are pivotally connected by means of links 66 and 67 (Fig. 5) to a central slide 68 mounted on the plate 7 beneath gibs 69. The slide 68 carries a roll 70 which engages a peripheral groove 71 formed in a cam cylinder 72* on the shaft 62. Thus after the cutters have been lowered by the straightening of the toggle and are held rigidly in their lowered position by a dwell in the cam 60, the cam 71 operates through the slides 42, 43 and 68 to draw the carriers rearwardly, the carrier guideways 45 permitting such movement, and the knives 3 and 4 are thus drawn through the welt to sever the welt ends. Each cutter carrier is guided in its rearward movement by a rib 29 on the head beneath it, which is embraced by depending wings 29 on the carrier (Figs. 5, 6 and 8). This construction also insures that the carriers 29 move inward and outward with the heads 5 and 9. During this movement they slide longitudinally on the squared sleeves 46.

The shaft 62 is driven during the operation of the machine from a pulley 137 (Fig. 3) through a Horton clutch the roll carrier of which is indicated generally at 138, 138, the sleeve within it being splined to the shaft 62. This clutch is controlled manually by the operative to start the machine but is automatically controlled upon the completion of one revolution of the shaft 62 to stop the machine. The roll carrier 138 is provided with the'usual lug 139 which normally engages a spring pressed bunter 140' (Fig. 2) to release the'shaft 62. The bunter-140 ismounted in a." chamber formed in an arm 142 which is pivotally mounted on a pin 143 secured to theback plate 65 so that the bunter can bewithdrawn from engagement'with the lug. Thepin 143 also carriesloosely a dog 144 arranged to engage a lug 144 =on the sleeve 138 facing oppo sitely to thelug 139, and hold the shaft in an'invariable position when it, is stationary to insure a uniform starting of the cycle of operations of the machine. The bunter 140 and dog 144 are withdrawn from the lugs 139 and 144, to permit the shaft to be driven by the driving pulley 137, by conin abracket 154 depending from the plate 7. The rock shaft 153 also carries afor wardly extending rod 155 which supports thehandle 145. When the operative raises the handle 145 the slide 148 is lowered which through the hook and pin connection rocks the arm 142 to remove the bunter 140 from its lug 139. To simultaneously remove the dog 144 from its lug 144 the arm 142 is provided with a pm 156 which when the arm 142 is rocked 1n the manner described engages a tail 157 on the dog 144 and rocks it downwardly about the pin 143. This permits the springs of the Horton clutch to rotate'the roll carrier 138 and grip the sleeve 138 to turn the shaft 62. While the clutch is in operating position the lugs 139 and 144* lie approximately side by side.

In order to immediately return the bunter 140 to a position where it may rengage its lug 139 and stop the rotation of the shaft 62 at the completion of a single revolution, the plate '149 carries a stop 158 which strikes a tail 159 on the hook 147' when the latter is lowered and rocks the hook 147 about its p votal connection with the slide 148 thereby causing the hook to be disengaged from the pin on the arm 142. The operative now re-.

leases the handle 145 which has sufiicient weight, through the connections described, to elevate the slide 148. As the slide 148 rises its upper end strikes the underside of the .arm 142 and elevates the bunter 140 into the path of movementof its lug 139. The dog 144 is yieldingly supported on the arm 142. by means of a spring pressed plunger 160 which holds the dog in the path of movement of itslng 144*. The hook 147 is actuated to again snap over the pin on the arm 142 by a spring pressed plunger 161 carried by the slide 148. The engagement of the lug 139 with the hunter 140 arrests the rotary movement of the roll carrier 138, the continued movement of the sleeve 138 frees the Horton clutch rolls, thus freeing the roll carrier from the shaft 62, and also carries the lug 14: 1 past the end of the dog 14.4; so that when the movement of the sleeve is checked by the roll springs, its return is prevented by the engagement of the lug Mi with the end of the dog 14- For convenience in delineation, the machine has been illustrated with the parts all in a neutral position, that is, with the heads 5 and 9 carrying the welt rests and cutters parallel to each other (see Figs. 1 and 5) and consequently the segments 11 and 2-1 in central position. It will be clear, however, from the foregoing description, that when the machine is at rest, ready for the insertion of a shoe, the heads 5 and 9 are at an angle to each other and in their outermost positions permitted by the upward movement of the treadle rod 18, determined by the engagement of the treadle with a suit able stop. At this time the cutters are raised as in Figs. 1 and 3 with the toggle broken.

In operating the machine illustrated in the drawin s the operative inserts a welted, unsoled shoe between the heads 5 and 9 and then depresses the treadle 19 to bring the welt rests into position in the welt creases at the opposite sides of the shoe. As the heads swing in, the operative manipulates the shoe until the mark 36 on the insole, if it be marked, registers with the edges 85 on the welt rests. After the welt rests have engaged the shoe the operative may, by applying further pressure to the treadle, cause tie welt rests to tighten the materials of the shoe at the welt butting points if considered desirable. That is. the upper sometimes bulges away from the opposite sides of the last, leaving spaces as indicated at c, Fig. 9, and the pressure of the welt rests 1 and 2 against the shoe may be made su'iiicient to force the stock over the margins of the insole and close up these spaces, as indicated in Fig. 10. This is particularly advantageous, of course, where this mechanism is to be used in connection with a tacking mechanism which will insert tacks in the shoe at the proper points to retain it in this position.

As soon as the shoe has been positioned properly the operative raises the handle 145 thus throwing in the Horton clutch 188, 138 The first movement of the machine is the lowering of the cutters into the plane of the guards 33 of the welt rests. The cutters are then moved longitudinally of the shoe to cut off or butt the ends of the Welt. If a tacking mechanism is used in the machine as in the machine shown. in the parent application), this mechanism then is operated to drive the required number of tacks into the butted welt ends, securing them to the insole of the shoe.

The cutters are next returned to the posi tion indicated in Fig. 3 and the clutch is thrown out, thus stopping the machine. The operative now removes his foot from the treadle to permit the heads to separate, and then removes the shoe from the machine. As soon as the handle 145 is released, the hook 147 rengages the pin carried by the arm 142 and the clutch controlling mechanism is again so connected that the machine may be started by another upward movement of thehandle. I

It will be clear from the foregoing description that some of the features of the invention, as, for instance, the welt butting knife operating mechanism, are not limited to use in a machine in which both ends of the welt are butted in one operation, as they are equally useful in a machine for butting the welt ends singly, and it will be further understood that the invention is not limited to the conjoint use of all the illustrated devices and mechanisms in a single machine.

It will be clear to those skilled in this class of machines and with the general objects of the present invention in view, that changes may be made in the details of structure, the described and illustrated embodi ment thereof being intended as an exploitation of its underlying essentials, the features whereof. are definitely stated in their true scope in the claims herewith presented.
