26 Claims.

of the shoe upper known as the fox lng area and then to apply to the cement-coated foxing area viously cemented rubber outsole is pressed against the bottom of the shoe and the marginal portions of the outsole are secured to the foxing strip by the cement and by vulcanization.

In performing the foxing cementing operation, it is important that the application of cement shall be limited accurately to the desired area in order that the upper edge of the stripe of cement shall not be either above the upper edge of the foxing area, where it may be exposed in the finished shoe, orbelow that upper edge with consequent liability that it will fail to secure the foxing strip fully to the shoe. By reason of the fact that the bottom of the shoe is not fiat, the upper edge of the foxing area, the diiierent portions of which are usually at a uniform distance from the bottom, varies in position heightwise of the shoe at different parts of the shoe. Furthermore, certain portions of the: shoe, such as at the shank, are undercut with respect tothe side of the shoe and it is essential that these portions shall be coated as well as those which are more nearly vertical.

The general organization of the machine disclosed in the parent application referred to above is such that the point of operation of a tool is caused to be transferred around the foxing area of a shoe by relative movement between the tool and the shoe. Thus the machine disclosed in the parent application provides for turning the shoe relatively to the tool and, mounting the tool upon a swinging arm, maintains it in contact with the shoe regardless of variations widthwise of the shoe in the peripheral contour of the foxing area.

An object of the present invention is to provide an improved foXing cementing machine of this type in which greater production and hence reduced operating costs may be secured without sacrificing the high quality of work.

In accordance with important features of the invention, there is provided a machine embodying a novel cement applying means by which a heavy coating of cement may be applied to the foxing area during a single relative traversing a rubber strip known as a foxing strip. A premovement between the shoe and the cementapplying means, the coating being deposited exactly upon the foxing area of the, shoe. In the illustrated construction, this cement-applying means comprises a conduit or trough by of which cement is caused to flow on the foxing area, said trough being provided with a shield the forward end of which contacts with the shoe at the upper edge of the foxing area to limit the spread of cement. A fixed receptacle of substantial size is mounted on the machine so as to underlie the point of contact between the cement-applying tool and the shoe, and the illustrated tool is provided with means for picking up cement from this receptacle to deliver it to the trough, driven spaced disk-like members from which the cement is removed by an interposed scraper being provided in the illustrated construction. The illustrated cement-applying tool is mounted so as to provide for movement of the tool heightwise of the shoe under the guidance of suitable shoe-engaging means and is held against the shoe with sufiicient force so that the edge of the shield will slightly indent the shoe, thereby to prevent the cement from creeping above the upper edge of the foxing area by capillary attraction These and other features of the invention will be best understood from a consideration of the following description taken in connectionwith the accompanying drawings, in which Fig. 1 is a front elevation of the complete machine with parts broken away and in section;

Fig. 2 is a horizontal section taken just below the shoe locating and clamping mechanism'and showing the cement-applying tool in position for operation upon a shoe the outline of which is indicated by broken lines;

ing tool to the shoe at the heel end and at the,

shank respectively.

In the machine herein illustrated, the shoe 10 to be treated is held in an upright position and rotated around a vertical axis by synchronized upper and lower driven clamps 12, 14 and 16 (Fig. 1). Before the machine is set in motion the shoe is located between these clamps by means of Locating devices 18, 20 engaging the toe and heel ends respectively when drawn down by a rod 28 connected to a treadle 30 and they are arranged above the operating zone so that they are out of the way. These locating devices are withdrawn from engagement with the shoe before the machine starts and the shoe is depressed to its operating zone before it starts to rotate. The shoe is supported with its bottom facing downwardly and is turned to present successive portions of the foXing area to a cementapplying tool. To allow for the changing contour of the shoe, a tool-carrying arm 260a (Fig. 2) is mounted to swing in and out and up and down and the varying speed and contour are compensated by mechanism described in the parent application Serial No. 395,346, of which against the upper edge of the foxing area 11 -(Fig. 1) to protect the shoe against spread of the cement beyond the foxing area, and means are provided for rocking the tool up and down as it is moved in and out.

This keeps the point of application of the tool strictly at the foxing area regardless of deviations of said area from a horizontal plane.

The lower clamp 16 embodies a detachable shoe-supporting plate 76 (Fig. 1). The locating devices 18 and 20 are pivotally mounted upon a casting forming part of a bracket 42. The upper clamping devices 12-14 are mounted on a shaft 72 journalled in an overhanging arm which extends outwardly from a portion 62 slidably mounted in a frame 32. Within this upright portion 62 is a shaft 94 which is connected to the shaft '72 and is arranged to be actuated by a drive shaft 108 whereby the upper clamp is rotated in synchronism with the lower clamp. The latter is driven through a hollow shaft by a connection through gears 92 to which power is supplied through the same drive shaft 108. Tilting movement is imparted to the shoe, as described in my earlier application, so as to present all parts of the foxing area 11 at approximately the level of the operating tool by means of a rod 110 which lifts the shoe-supporting plate 76 for pivotal movement around a cross bolt 84.

The machine, as illustrated, is driven by power supplied from an electric motor (not shown) connected to a shaft 152 and power is supplied through a clutch 162 of the one-revolution type controlled by a treadle 164 and thence through. gearing 1'72 to a cam shaft 174. An

intermittent gear drive, not illustrated herein,

transmits power from the cam shaft 174 to a jack shaft 176 so as to rotate the shoe during about two thirds of the cycle of the cam shaft. This allows time intervals before and after the rotation of the shoe for other power operations such as jacking the shoe and backing on the tool carrying arm. Motion of the jack shaft 1'76 is transmitted to the upright sleeve 80 carrying the lower shoe clamp by means of a train of gears including the gears 92, and a continuation of this gear connection actuates the drive shaft 108 to rotate the upper clamp in synchronism with the lower clamp.

Inasmuch as the shoe is rotated about its central axis at a constant angular velocity, the cement-applying tool, which is carried at the outer end of the swinging arm 260a, 260 and urged against the shoe by a spring 261 (Fig. 2), would operate along parts of the shoe having a varying radius and, consequently, the tool would move along the foxing area 11 at a varying speed. To overcome this, there is provided a compensating mechanism by means of which a spindle 262, upon which the tool-carrying arm 260 is pivotally mounted, is caused to follow a path (herein shown in Fig. 2 as an elongated ellipse 264) such that, in combination with the rotation of the shoe, it will give an approximately uniform, progressive movement of the tool relative to the shoe. The spindle 262 is carried in a toggle-like support including a hinged arm 274 (Fig. 1) and its movements are controlled conjointly by an eccentric-operated link 232 and a plate 286 which are driven through power supplied by a double crank 294 energized from the drive shaft 108. A hand lever 320 mounted on the front of the machine may be adjusted to control the compensating mechanism so that it will care more readily for shoes of different ranges such as mens, women's and childrens. At the completion of the cementing operation the tool is moved away from the shoe by a b:eklng-off mechanism acting through an idle gear 552 (Fig. 1) and a pinion 350 fastened on the tool-carrying arm 260 to carry the tool away from the shoe a few inches. 0

The machine a shallow cement receptacle 400 (Fig. l) positioned on the top of the frame 32, this receptacle being formed integrally with the upright braclrwt 42. This receptacle is provided with a c a1 boss 402 (Fig. 2) for the passage of the shoe ciamp carrying shaft 80 so that the shoe may be positioned and rotated above the receptacle. The cement-applying tool is mounted upon the tool-carrying arm 26%. This arm 260a is provided with a pivoted extension 404 (Figs. 3 and 8) pivoted on a horizontal spindle 406 and normally held in substantially horizontal position with its weight balanced by a spring 408 (Fig. 3). This extension 404 carries at its outer end an upright framework 410 I in which is provided a bearing for a stub shaft 412 (Figs. 4 and 5) used for supporting the rotatable pick-up disk 414 which has a plurality of grooves 416 with parallel disk-like flanges around its periphery. The stub shaft 412 has an integral collar 418 (Fig. 5) to which is attached by screws a gear 42f). This gear meshes with a pinion 422 on another shaft 424 to which there is connected one end of a flexible shaft 426 passing over a hook 428 (Fig. 8) on the arm 260a and connected by means (not shown) to one of the shafts of the machine so as to rotate the disk 414 during the operation of the machine. The disk 414 is connected to the collar 418 by means of a driving pin 430 and is detachably held on the end of the stub shaft 412 by a removable spring cotter pin 432. This allows for the ready removal of the disk 414 for cleaning.

Between the disk 414 and the gears 420, 422 is a cover 434 held by screws (not shown) which may not be removed to give access to said gears. A packing ring 436 is interposed between a hole at the center of the cover 434 and the edge of the integral collar 418 to prevent cement from working into the gear case. Another cover 438 surrounds the connection between the flexible shaft 426 and the pinion shaft 424. The casting of the frame-work 410 also extends around the margin of the wheel at the front thereof to provide a cement-directing means or trough 4 40 (Figs. 4 and 6) over which flows cement picked up by the disk 414 and transferred to said trough by flexible steel scrapers 442 interposed between the flanges of the disk. These scrapers 442 are screwed at one end to the trough and each substantially fills one of the grooves 416 of the disk and removes cement on the adjacent sides of the flanges. Thus the constantly driven disk 414 picks up cement from the receptacle 400 and causes it to flow down the trough 440 to be deposited on the foxing area 11 of the shoe.

It is essential to the proper operation of the machine that the cement shall exactly cover the foxing area without extending above the upper margin thereof and accordingly a curved shield 444 is mounted directly above the trough 440 and provided with a curved forward end, as shown in Fig. 8, which is sufliciently sharp (Fig. 4) to form a distinct line of division between the foxing area and the rest of the upper of the shoe without being sharp enough to damage the shoe.

Preferably the pressure of the cement-applying tool against the shoe as effected by the spring 261 is such as to cause the forward edge of the shield 444 slightly to indent the canvas cover to form a crease and thereby to prevent spreading of the cement above the foxing area by capillary action. This shield 444 is an extension of a curved cover member 446 which is ivotally mounted on the frame-work 410 by means of a removable pin 448 (Figs; 4, 5 and 8). The shield 444 is pivotally attached to the extension 446 by a transverse pin 449 and held rigidly thereon by threaded pins 450 and 451 carrying wing nuts 452 and 453 which clamp the shield to the extension 446. The pin 451 rests in a groove 454 (Fig. 4) in the frame-work so that the shield 444 and extension 446 as a unit may be tipped up around the removable stud 448 to give access to the disk and scrapers and. to permit the removal of the disk 414.

It will be obvious that some portions of a shoe have a sharp corner at the lower margin while other portions of the shoe are undercut as at the shank. At such places, as illustrated in Fig. 10, a flow of cement directly down from the point of contact of the shield 444 with the shoe would not deposit any cement on the shoe. Accordingly, yielding means such as a hinged deflector and wiper 456 is provided which is pressed upwardly against the bottom of the shoe by a coiled spring 458 (Fig. '7) surrounding its pivot pin 460. This wiper 456 constitutes in effect an extension of the trough 440 and directs or deflects the stream of cement to cover the whole width of the foxing area even in those portions which are undercut, such as at the shank. The wiper 456 is mounted on a thin plate 462 positioned directly under the lower edge of the trough and mounted for swinging movement about an upright pivot pin 464 (Figs. 6 and '7). To this end the plate 462 is screwed to a small casting 46S journaled on the pivot pin 464 and is allowed to give slightly vertically against a surrounding spring 468. The pivot pin 464 extends into the upright frame-work 4.10 (Fig. 8) upon which the other parts of the tool are mounted.

It will be recalled that means are provided for tilting the shoe about the ball line so as to bring the toe portion of the foxing area to approximately the level of the heel portion thereof. This arrangement to a large extent compensates for the differences of level between diiierent parts of the ioxing area but does not take into account the arched shank portion of the shoe or any other slight variations in level. Accordingly, means are provided for guiding the tool around the shoe so that the edge of the shield 444 will travel exactly along the upper edge of the foxing area. To this end, the extension arm 404 has attached to it a control arm 4'70 (Figs. 3 and 4). This arm 4'70 is clamped by a screw 4'72 (Figs. 3 and 8) on an uprightpivot pin 4'74 mounted in ball bearings in the extension arm 404. A spring 4'76 interposed between the extension arm 404 and the control arm 4'70 thrusts the outer end of the control arm toward the shoe to a limit defined by an adjustable stop screw 47S held in adjusted position by a lock nut 480. On the outer end of the control arm 4'70 there is provided an upright pin positioned at a'compound angle with respect to the shoe (see Figs. 4 and 8) and on this pin is mounted for free rotation a thin disk 482 surmounted by a roller 484' The utility of this arrangement will be best understood by a consideration of Figs. 9 and 10 from which it will appear that the disk 482, the edge of which may be serrated ifdesired, is held against the bottom of the shoe and tends always to drag the roller 484 into contact with the corner of the shoe whether it be a sharp corner as in Fig. 9 or a curved shank portion, such as is illustrated in Fig. 10. By-

this contact between the disk 482 and the bottom of the 'shoe the control arm 4'70 is forced to swing up and down and to carry with it the extension arm 404 for movement around the horizontal pivot pin 406 (Fig. 8). This carries the edge of the shield 444 up and down so as to follow exactly the upper edge of the foxing area and to coat a portion of uniform width, considered vertically, around the whole. periphery of the shoe, thus contributing very, materially to the successful operation of the machine.

In order that the width of the stripe of c ment to be applied to the shoe may be varied to meet the wishes of various shoe manufacturers, the upright frame-work 410 carrying the cement-supplying disk 414 and the shield 444, as well as the trough 440, may be adjusted V61? tically on the extension arm 484. To this end a dove-tail rib 486 (Fig. 8) is provided at the enclof the extension arm 404 and a corresponding groove provided in the upright frame-work 410 so that said framework may be adjusted vertically on the arm 404 by means of a screw 488 threaded into the rib 486 having a head 489 mounted against axial movement in a cover 490 (Fig. 4). When the screw 488 is rotated in the cover 490 lifts or depresses said cover with respect to the arm 404 and also moves the frame-work 410 to which the cover is secured by screws. This adjustment does not affect the position of the control arm 4'70 and therefore varies the relation of the edge of the shield 444 to the bottom of the shoe so as to apply a wider or narrower stripe. A lock screw 492 (Figs. 4 and 8) bears against a gib 494 to clamp the framie-work in adjusted position on the dovetail rib 486."

At the close of a days work the shield 444 and the extension'cover 446 may be swung clockwise (Fig. 4) around the pin 448 and, if desired, re-

moved from the machine for cleaning by pulling the pin 448 out of the frame-work. The removal of the cotter pin 432 permits removal of the disk 414 after the spring scrapers 442 have been lifted out of the grooves in the margin of the disk. The narrow deep grooves 416 in the margin of the disk pick up considerable quantities of cement from the receptacle 406 and deliver it to the trough 440 where it flows on to the foxing area of the shoe under the guidance of the shield 444, the wiper 456, and the control arm 470. Any surplus cement removed by the flexible wiper 456 flows back into the receptacle.

Supposing that the machine has been arranged for foxing cementing as shown in the drawings, the operator will place a shoe to be cemented upon the lower clamp 16 and, depressing the treadle 30 (Fig. 1) to bring the locating members 18 and 20 against the shoe to center it on the clamp, will if necessary move the lever 320 for adjusting the compensating mechanism to a position determined in advance as most suitable for the particular size of shoe to be treated and lock it there by the handle 323. For the cementing operation, the machine is set up with a sleeve 46 which, as described in the parent application, controls the overlap, in such a position that, when the machine is started, it will give the shoes one complete revolution plus a small predetermined overlap designed to ensure complete coverage of the foxing area. The treadle 30 may then be released and the starting treadle 164 depressed to close the clutch and transmit the power of the motor to move parts of the machine. This will cause the arm 60 supporting the upper shoe clamps 12, 14 to be moved down so as to clamp the shoe and to depress it to the level of the operating tool, as shown in Fig. 1. The backing-off mechanism will allow the tool to be moved gently into contact with the shoe under the impulse of the spring 261. An intermittent drive mechanism will then start the rotation of the shoe to carry all portions of the foxing area 11 past the cement-applying tool. During this rotation of the shoe, the compensating mechanism will move the pivotal support for the tool-carrying arm 260 through an elongated path such as that shown in Fig. 2 so that the position of the tool will always be advantageous with respect to the shoe. It will be assumed that the cement-applying trough 440 and shield have been adjusted vertically with respect to the carrying arm and the bottom contacting disk 482 by means of the thumb screw 489 so that the edge of the shield 444 will contact with the shoe exactly at the upper edge of the foxing area. This adjustment will depend upon the heightwise width of the foxing area desired by any particular manufacturer and will only need to be changed at rare intervals in the case of a radical change in the style of shoe to be cemented. During the rotation of the shoe, cement will be picked up from the receptacle 400 by the driven disk 414 and delivered to the trough 440 by means of the scrapers 442. The cement in quantities in excess of what is needed will flow down the trough as indicated in Figs. 9 and 10 across the foxing area of the shoe and any surplus cement will drop back into the receptacle 400. This falling cement will be deflected into contact with undercut portions of the shoe as in Fig. 10 by the deflector 456. The level of the tool as a whole and hence of the edge of the shield will be determined by means of the disk 482 and its associated roller 484 contacting with the shoe near its peripheral corner. After the shoe has made a complete revolution so that the whole of its foxing area has been cemented, the backing-off mechanism will operate to push the tool away from the shoe a predetermined minimum distance of perhaps two inches, which distance will be the same regardless of the size of the shoe being coated. At this time, the intermittent drive will have brought the shoe to rest easily and the movement of ti e shoe will cease before the one-revolution clutch disconnects the motor from the drive shaft of the machine. The power of the machine is then utilized for raising the upper clamp by lifting the arm 60, 62 by the action of a track on the cam 240 shown in Fig. 1.
