COATING APPARATUS.

Application filed August 18, 1920. Serial No. 404,426.

T 0 aZZ whom it may concern Be it known that I, IRA C. BUCKMINSTER, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain I mprovements in Coating Apparatus, of wh ch the following'description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to apparatus for the application of fluid substances to various objects, it being more particularly adapted for coating shoe parts with an adhesive. The embodiment of the invention which I have chosen to illustrate is organized for cementing both the foxing area and bottom of a shoe. In laying the soles of rubber-soled shoes, the usual practice is to cement them to the shoe bottoms, and effect a more perfact union between the edges of the soles and the uppers by cementing between them, about the entire lower edges of the uppers, strips of thin, high-grade rubber, termed foxing. The area over which a foxing is laid varies considerably both with respect to its transverse curvature and its angle to the shoe bottom, approaching more closely a straight line and making a more obtuse angle to the bottom at the shank portion than at the heel and toe portions. Moreover, between shoes of different sizes variations in curvature and angle occur in the same portion. These peculiarities of contour and relation render the foxing area extremely difficult to cement by machine, especially in view of the fact that the upper edge of the cemented surface must be even to avoid marring the shoe upper, and since it is desirable to simultaneously coat the bottom. Objects of the present invention are to provide an apparatus by which the coating for attaching the foxing may be applied rapidly and uniformly, with a sharply defined edge, and by which the bottom may, if desired, be coated at the Same time as the foxing area. In the accomplishment of the above purposes, a feature of the invention consists of a spring member having convolutions furnishing an applying surface. Preferably, a

shoe uppers, irregularities exist in the sur-' face to which the fluid is applied, this being produced, for example, by the seams which join the vamp to the quarters. In operating over these irregularities it is diflicult to apply a uniform coating. In relative movement of the applying member and work in one direction, as from the higher to the lower surface lapping at the seam, said applying member tends to jump over the lap, leaving an uncoated transverse strip along the -seam. Upon movement in the opposite direction, or when the applying member acts against the raised edge of the lapped portion, an excess of the fluid is deposited at the seam. A feature of the invention overcoming this difliculty involves novel means for alternately acceleratin and retarding the movement of the applying member. Thus an applying member which is moved at a constant rate is also oscillated by cam mechanism, its movement being alternately accelerated and retarded. I have shown a rotatable driving member with a lever fulcrumed thereon, there being connections between the lever and applying member. Upon this connecting chain the cam, or other oscillating means, may act. The result of this is to more uniformly distribute the fluid, forcing it into the angle between the layers by the oscillation in one direction, and drawingit away in the opposite direction. The effect over the entire area. operated upon is, in fact, to work out or equalize the coating.

A further feature of the invention involves relative movement between the work and applying member, which brings about the presentation of the entire area to be coated to the latter. I prefer to employ a rotatable applying member, and adjacent to one extremity only of this a rotatable feeding member. The direction of rotation of these members is opposite, and in consequence the applying member places upon the work not only a coating which is rubbed in by the direct contact of the member with the surface to be coated, but also a portion which is laid upon the surface already treated, as just indicated, but without the rubbing action. By this means a thicker coating may be obtained. As shown herein, the

feeding and applying members are arranged for relative movement laterally of their axes, the feeding member preferably having a sliding hearing which permits it to yieldably follow the work in its movement.

In cementing for the foxing or in like operations, it is convenient to have a bottom rest along which the work is moved to maintain it in a definite relation to the applying member. In this connection, as a feature of the invention. I furnish novel means arranged to change the angular relation of this rest to the area operated on. This enables the operator to shift the shoe with respect to the applying member to cause correct :10 tion over the differently inclined shank portion and heel and toe portions. As the width of the applied coating should remain constant regardless of the angular variation just mentioned, the work-rest when thus arranged is preferably movable about a normally fixed point located approximately in its work-engaging surface. But since in connection with different pieces of work it may be necessary to alter the width of the coating, 1 have also shown means arranged to vary the normal position of the rest along the applying member.

Still another feature of the invention concerns novel means for simultaneously coating a plurality of work surfaces, as the foxing area and bottom of a shoe. With each of such portions an applying member cooperates, these members being independently supplied with the coating fluid. I may, for coating one of the work surfaces, utilize a rotatable work-rest. On account of the preferred location. of the associated applying means, this second applying means or workrest has an upwardly extending work-en-.

gaging surface, and upon this surface the coating fluid is delivered. To counteract the effect of gravity, this applying member may include means for elevating the fluid along its surface, and preferably has combined with it means for retaining the excess of fluid which it receives. The disclosed embodiment of the invention has, for supplying the coating fluid to the applying members, an elevated reservoir with a separate and independently controlled outlet for each member, but delivering initially to one of them.

Upon consideration of the following description and claims, with the accompanying drawings, other features will become apparent. In these drawings,

Fig. 1 is a broken front elevation of one form which my invention may assume;

Fig; 2 is a top plan view thereof with a portion broken away;

Fig. 3 is a vertical section on the line 3--3 of Fig. 2;

Fig. 4c is an enlarged vertical, sectional detail through the applying members; and

Figs. 5 and 6 are vertical, sectional details on the lines 55 and 6-6, respectively, of Fig. 4.

The frame of the apparatus includes a standard 10, rising from a. base 12, which may be adapted to be secured to a bench 14. Rotatable in horizontal bearings in the standard is a shaft 16, here shown as tubular. At one extremity of the shaft is mounted an applying device or roll comprising an. annular body 18, at the ends of which are formed outwardly extending flanges or walls 20 and 21. (lo-operating with the outer surface of each wall and secured to the body by screws 22 are disks 24, 24. The spaces between these disks and the body flanges receive the angular ends 26 of helical springs 28, the springs being thus clamped between the flanges and disks, the latter of which are drawn intocontact with the springs by the screws 22. The springs are situated side by side in a circular series, the succeeding springs being in close proximity toone another, or in substantial contact, thus furnishing an almost continuous applying surface. Each spring extends in the general direction of the axis of the shaft 16, but is shown as slightly inclined downwardly and outwardly, so that the applying surface has the form of a truncated cone. This inclination of the surface permits the operator to more conveniently present the work thereto, a shoe in a considerable portion of its passage beneath the applying member being held with the axis through the cone of its last in a substantially horizontal position. It is to be noted that the spring-supporting flange 21 is inclined outwardly from the vertcal. This avoids interference with the yield of the inclined springs as the work is pressed against them. The convolutions of the springs are somewhat separated, preferably by putting them under slight tension when mounting them upon the supporting walls. The spaces thus provided give pockets holding the cement for application to the work, the grooves between the adjacent springs also furnishing other pockets extending the full Width of the applying surface.

The shaft 16 is preferably rotated to produce a constant advance of the applying surface over the work, by a driving member in the form of a gear 30 free to turn to some extent upon the shaft. The gear meshes with a pinion 32 formed upon the hub of a pulley 34 mounted upon a spindle 36 projecting from the standard within a casing 38 formed at the end thereof. The pulley 34 is belted to some suitable source of power. The connection of the gear 30 to the shaft 16 is through a lever 40 fulcrumed at 42 upon the outer face of the gear, and having its longer arm connected by a link 44 to an arm 46 clamped upon the shaft 16. This lever, link and arm communicate the rotation of the gear to the shaft. At the same time, the shaft is oscillated by a projection 48 from the short arm of the lever 40, this projection entering a groove 50 generally sinusoidal in form, or arranged in curves at alternately increasing and decreasing distances from the axis of a cam-disk 52 supported upon the shaft and held against rotation by a connection 54 to the frame. As the gear 30 is turned, the projection 48 contacts in succession with a trough a and then with a crest b of the cam-groove. As a result of this, there is imparted to the lever a movement of oscillation which is communicated through the link 44 and arm 46 to the shaft 16. The rate of movement of this os-' cillation is greater than that at which the shaft is rotated, so that the applying surface moves back and forth circumferentially as it is advanced by the driving member.

To assist the operator in moving the work past the applying device to receive its coating therefrom, there is provided at the outer serrated at its periphery to more effectively engage the work. This disk is rotatably' mounted, by a hub 58 projecting from one side, in a block 60 arranged to slide vertically in ways in a plate62 bolted across the side of the standard. At the inner side of the plate is a recess 64, in which the feeddisk operates, the wall of this recess holding the disk in contact with the outer face of the body-disk 24. Through the hub is an axial opening squared to receive a correspondingly squared end 66 of a shaft 68 extending through the openin'g in the shaft 16. At the opposite extremity, this shaft 68 is rotatable in a bearin 7O trunnioned upon a bracket 72,-rising rom the opposite side of the standard from the applying device.

Arranged to turn about the shaft 68 is a,

gear 74 meshing with a pinion 76 formed upon the hub of a pulley 77 driven from the source of power in a direction opposite to that of the pulley 34. At the outer side of the gear is a disk 78 splined to the shaft and pressed against the end of the gear hub by a spring 80 surrounding the shaft and bearing at its outer extremity against one of a pair of nuts 82 threaded upon the shaft 68. This arrangement furnishes a frictional driving connection between the gear and the feedlng shaft, so that in event of the work not being advanced as rapidly as the disk 56 turns, the latter may slip without injury to the work. The shaft 68 is of considerably less diameter than the opening through the shaft 16, sov thatit may play laterally upon its trunnions. The feed-d sk is held normally downward, projecting below the adjacent applying surface of the device 18, by

a spring 84 situated in a recess in the plate 62 and bearing against the top of the block 60. As the work is pressed against the feeddisk to bring the former against the applying surface, said disk rises against the tension of the spring to permit the effective engagement of the work with the applying surface, yet is always held in feeding con-v this rest adjacent to the applying roll being spaced from the disk 56 by an amount approximately equal to the width of said area. As illustrated, this work-rest consists of a cone 86, the apex of which is in close proximity to the app-lying surface, while the base liesbelow it at an angleto the horizontal, end of the body 18 a feed-disk 56 milled or giving a work-engaging surface, furnished by the wall of the cone, which is approximately vertical. The rest may serve also as an applying member, and to this end, is rotatable, preferably in a direction opposite to that of the feed-disk. As illustrated, it is fixed upon a spindle 88 turning in a bearin member 90 and operated by a flexible shaft 92 geared to the source. of power, the connections between the shaft and source not appearing inthe drawings. The bearing member is carried upon theend of segments 94, 94 joined to the ends of said member at opposite sides of the standard, and having in their outer faces segmental grooves 96 which receive series of rolls" 98 arranged along arcs of circles upon upports. 100 depending from the ends of a yoke 102. The centers of the arcs along which the axes of the rolls are located lie approximately in a. line passing through the apex of the conical rest 86, and therefore in the work-engaging surface. The yoke 102 is mounted to slide at 104 upon the frame, and has a threaded opening to receive a screw 106' arranged to turn in a lug 108 projecting upwardly from the frame. The surface upon which the yoke is supported is inclined at substantially the same angle to the horizontal as is the under side of the applying surface, so that When it i moved by the screw, the apex of the cone is caused to travel along said surface. This varies, as desired, the distance between the work-engaging surface of the rest and the feed and gage-disk 56, and thus alters the width of the area coated by the applying member. The rest may beheld in its normal position, which may be considered as that occupied while the heel and toe portions of a shoe are being coated, or with the bottomengaging surface in an approximately vertical position, by the weight of the parts, though a spring mav be used, if desired, to insure the maintenance of this relation. For coating the shank portion ofthe shoe, this surface and that of the'applying device should lie at a more obtuse angle, as illustrated in dotted lines in Fig. 4 of the drawings. To effect this change in position, there is connected to the bearing member a cord or flexible member 110, passing over a guidepulley 112 and being joined to a treadle 114, shown as fulcrumed upon the floor beneath the bench. lVhen in the movement of the work beneath the applying roll one side of the shank portion is reached, the operator may depress the treadle, thus shifting the work-rest and bringing its engaging surface to the position which will present the foxing area over the shank in the proper relation to the applying surface. Since this engaging surface of the rest moves, by virtue of the relation of its arcuate guides,-' about a point at its apex fixed with reference to the gage-disk 56, the width of the area coated will not be altered by this adjustment. After the shank portion is passed, the treadle may be released, allowing the rest to return to normal for the coating of the succeeding heel or toe portion.

Cement or other coating fluid is preferably supplied to the springs 28, and, if desired, to the bottom rest 86, from a reservoir 116 supported upon the top of the standard above the applying device through an out.- let controlled by 'a valve 118. Below the valve is adelivery'passage 120 for the applying roll, and just at one side of this is a passage 122 of less width than the passage 120, for delivery to the bottom rest. The flow through these delivery passages is res'pectively controlled by pairs of slides 124, 124 and 126, 126 mounted to move in de- .pressions in the top of the standard, and

guided and limited in their travel by screws 127. The adjustment of these slides may be effected by screws 128 threaded through end portions 130, depending from the slides and having their ends contacting with the frame. At opposite sides of the opening 120 are yieldable wipers or retaining members 132, preferably consisting of some such fibrous tamper material asfelt, and being inclined downwardly and inwardly toward the center of the applying device. These wipers, by their yield, are capable of conforming sufficiently to the surface of the applying device to prevent too free movement in the direction of rotation, and to substantially wholly arrest the flow of cement in the opposite direction, or down the ascending side of the roll. Es-

cape of the cement at the ends of the applying device is prevented by a contact-plate 133 at its inner extremity and the plate 62 which is drawn against the outer extremity. The passage 122 delivers first to an annular groove or depression 134:, carried by the body 18 of the applying device and being formed conveniently by the disk 24 and a parallel wall spaced therefrom. Into this groove extends a scraper 136 fixed to the frame, this scraper dofling the cement from the groove and causing it to fall upon the upwardly inclined top of the cone 86. The

excess of cement flowing down over the cone is retained in proximity thereto to be used by it as needed, by a wall 138 rising from the inner side. of the bearing member 90 and extending in a direction generally.

groove 140 encircling the work-engaging surface of the cone in a left-handed direction for its right-handed rotation to cause it to exercise its elevating function. wall of the cone between the apex and the circumference of the base is not, in the embodiment of the invention illustrated, strictly conical, it being curved upon a radius of considerable length tomore closely conform to the curved bottom surface of the shoe which is to be coated. The length of this applying surface between the apex and base is such that it operates over more than half the width of the sole, and thus upon the passage of the entire circumference of the shoe over the foxing-cementing roll the shoe bottom will be completely coated by the The side.

groove 134 to the bottom rest, the operator,

starting, for example, at the toe of the shoe,

" work, permitting the latter-to be forced against the springs, which conform to it. Consequently,the cement which is carried between the convolutions of individual springs and in the ooves between adjacent springs is deposite upon every portion of the area with which the springs contact between the disk and the cone. Since the applying roll turns in a direction opposite to that -in which the work is advanced, the cement is not only directly applied by the springs to the surface operated on and rubbed into it, but the cement brought down by said springs is deposited upon the surface thus coated and carried away by it without being subjected to this rubbing action of the springs upon the work. In this way a thicker coating may be deposited upon the upper, the first application preparing the surface to better receive that which follows, preventing the drawing together of the cement which tends to occur if it is laid directly without a working-out action upon the surface to be coated. At the seams the oscillation of the applying roll, superposed upon its rotation,- works the cement into and out of the spaces at the ends of the lapped material, insuring against either an excess or deficiency at these points. At the same time that the .foxing area is being coated, the cement, falling through the roll-groove upon the bottom rest, retained by the wall 138 and distributed over the conical surface by the groove 146, is carried to the outer Wall of the cone and deposited upon the shoe bottom; Here it is rubbed in and deposited without such rubbing effect, similarl to the faxing-cementing roll. shank portion, lying at a substantially different angle than the toe portion, is reached. At this time the operator depresses the treadle 114, swinging the rest upwardly about its apex, which remains in unvarying relation to the applying surface of the roll.

The operator following the movement of the rest with the shoe, the work is brought to the position indicated indash and dot lines at s. \Vhen the shank portion is passed, the operator releases the treadle, and the roll acts upon the heel portion in a manner similar to that in which the toe has been cemented. Upon the opposite side of the shoe the treadle is again depressed and released for the coating of the shank portion, and

This action continues until the the advance of the work continues to its completion at the toe. During this passage of the foxing area beneath the springs, the entire bottom surface of the shoe has been eemented by 'the' conical rest.
