WILLIAM GILBERT CHENEY, OF MARLBORO TEASSACIlI-I'U'SETTS, ASSIGNOR TO UNITED SHOE MACHINERY CORPORATION, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY.

. Application filed September 13, 1919. Serial No. 323,495.

To (ZZZ whom it may concern:

Be it known that 1, WILLIAM G. CHENEY, a citizen of the United States, residing at Marlboro, in the county of Middlesex and State of Massachusetts, have invented certain Improvements in Coating Apparatus,

of which 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.

My invention relates to apparatus for applying fluid coating to such objects ,as

shoes. More especially is it designed for.

able applying member, as a brush, within which is carried means, as a gage disk situated between the fibers of the brush, to

determine the marginal line alongwhi-ch coating is to be applied to the work. By this arrangement, when the work, for example the lasted upper of a shoe, is forced into the fibers, both the bottom and the edges above said bottom are coated, the latter to a height determined by the space between the peripheries of the brush and gage.

To facilitate the proper application of the coating to shoes, so that excessive pressure shall not be required to effect the coating of the edges as well as the bottoms, there is furnished as another feature of the invention an applying member in which is a depression approximatingin depth the height of the foxing line above'the shoe bottom. Preferably the width of this depression is that of a relatively narrow portion of the shoe bottoms to be cemented. rangement application to all ,the foxing surface is assured.

As a further feature of the invention, I

have a member forcontact with the work extending along the rotatable brush or other -applying member in the same direction as the axis of rotation, the opposite extrem- By this ar ities of the contact member being variable in their relation to the aXisof the applymg member. This contact member may be a work-supportingroll and may cooperate with an applying brush the axis of rotation of which is horizontal. By separate vertical adjustment of the ends of this roll, the work advancing over it may be presented to the brush in the desired relatioIT.

Other features will be hereinafter developed, reference being had to the accompanying drawings, in which, i i

Fig. l is a side elevation of one embodiment of the invention;

Fig. 2 is an end elevation looking from I the left in Fig. l, with a portion broken away; and

Fig.3 is a detail in elevation of the brush with the upper portion in section.

Iii-bearings 10 near the top end walls of a suitable trough-like receptacle 12 is journaled a shaft. 14:, carrying fast and loose pulleys 16 to which power may be applied from a suitable source by a belt, not illustrated. WVithin the receptacle there is secured to the shaftby set screws 18 an applying member A. This is shown as consisting of a cylindrical core 20 between end flanges 22, 22 on which are situated radial tufts of fibers 24:, the outer ends of which present a generally cylindrical surface dipping in the body of cement or other coating fluid contained in the receptacle,and bringing it up for application to the work pressed against the upper ends of the fibers. Ex tending aboutthe brush near; its longitudinal center is shown a depression 26 formed by fibers ofless length than those uponeach side of the depression. The depthof the 'sidered at the foxing area, so that the longer fibers'at each side of the depression may with certainty contact with this portion, yet may bedefiected laterally and maintain their contact with the wider parts- The length of the fibers should be sufficient. to permit this yield without their rubbing too heavily upon the work and thus tending to brush off the applied fluid. I i

Fixed to the core between the tufts of v portion beyond the disks should be such as toassure the proper brushinoon of the coating fluid to the bottom of the shoe. As illustrated, the disks are symmetrically arranged at each side of the center of the depression, furnishing a stable support for the work without tendency to tip laterally when it bears against them.

Preferably at opposite sides of the brush just within the edges of the receptacle walls,

there extend parallel to the axis of rotation contact members furnished by rolls 30 and 32. The upper edges of these rolls are substantially alined in a horizontal plane with the upper points of the gage disks, so that the work will be supported for advance in a straight line as it is pressed across the rolls and brush. The roll 32, which is at the forward side of the brush,- in addition to its Work supporting function may also serve by contact with the bottom of the shoe to remove therefrom any excess of the ap plied fluid. The rolls are journaled at their ends in bearing plates 34, preferably fixed to a supporting bar 36 for the rear roll and a rod 38 for the forward roll, by screw and vertical slot connections 40. By independent adjustment of the end bearings of the rolls their angle to the horizontal may be altered. until they so contact with the curved shoe bottoms that these are best pretrated, is fixed rigidly to the top of the resented to the brush to attain uniformity of the upper foxing line. The bar 36, as illusceptacle, but the rod 38 is hinged at 42, allowing'the roll 32 to be turned back clear of the receptacle, giving access to it for the introduction of the coating material. The receptacle may be emptied when desired by the removal of a plug 43, normally closing an opening in an end wall of the receptacle near the bottom.

Beneath the roll 30, between the ends of the receptacle, extends a rod 44:, and partly surrounding this is a scraper 46, which may be of spring material with its upper edge bearing against and preferably conformiir to the outline of the periphery of the brush. Projecting upwardly and rearwardly from the scraper is an arm 48 at the upper end "of which is an opening to receive a screw 50 threaded through the wall of the receptacle,

this screw having fixed to it at each side of the arm collars 52. By rotating screw 50, the scraper may be turned about the rod 44 so that its engaging edge may be varied in its relation to the brush to remove therefrom more or less ot'the coating fluid. This enables the operator to change the amount brought up for application to the work.

In using the apparatus for applying cement to such work as the bottom and lower edge of the upper of a lasted shoe, as is illustrated at S in Fig. 3 of the drawings, the operator presents the work with one extremity, as the toe, to the brush in a position downwardly inclined to the horizontal,

the bottom resting upon the roll 30. It is forced into the brush sufficiently to coat the foxing area at the end of the toe, and then advanced over the brush and simultaneously swung downwardly upon the roll 30. The shoe in its travel now rests upon this roll and the disks 28, the bottom being cemented by the brush fibers of the depressed portion 26 and the edges of the fibers of the elevated side portions contacting with the foxing area to coat this, the marginal line of the coated portion being fixed by the radial distance between the peripheries of the disks and the ends of the fibers. Thus there is correspondence between a characteristic of the coated area, in the present instance the width, and the relation, radially of the brush, of the peripheries of the gage-disks to the ends of the brush-fibers furnishing the elevated portions. These fibers yield as the shoe widens and return to their original positions as the narrower shank portion is reached. In this advance the work passes upon the roll 82, which maintains the horizontal position of said work after the heel portion has left the roll 30. hen the heel reaches the forwardside of the brush, the work is again tilted but oppositely to that of the presentation of the toe, thus coating the foXing area at the extremity of the heel.
