To all whom it may concern:

Be it known that I, Fanomrox M. Fpnmm, a citizen of the United States, read; at Revemin the county of Suifolk an State of ssachusetts, have invented wrtain Improvements in Coating Apparatus, of which t e following description, n con nection wit the acco anymg drawings, a specificat on, like re erence characters on 10 the drawings indicating like parts in the several figures.

This invention relates to apparatus forapplying to \various objects a coating substance, as. for covering w1th blackmg or 16 other stain the perip eral portions or sides of shoe-heels. It is more particularly adaptthrough the applying and gage members and more closely associated arts; and a Fig. 5, a detail, part y in section, of the strfipmg device for the feeding disk. e frame 10, ,with its receptacle 12 for the blacking or other substance which is to be a plied to the work, together with some of t c minor devices, generally resembles those of the crest heel blacking machine, which is the subject of tent No. 1,025,523, Furber, May 7, 1912,- an need not herebedescribed. In the frame is iournaled horizontall a main driving shaft 14 extending from t e front to the rear and joined by a worm and worm-wheel 16 to a transverse intermediate shaft 18. This latter shaft is between definite lines, determined by the rand-crease at one side and the junction be- 1 tween the base and lift at the other, withis the portion 26 is out of axial alinement with the portion 22, it beinfiinclined downwardly with res t to the orizontal from ed for o rat upon heel-bases to which geared at 20 to a section 22 of an operating are at ed ru ber lifts. shaft, which turns in a bearing transversely In the use of heel-blacking'machines for of-the ap ratus at the front of the frame. 20 the pur just indicated, there is pre- C0nn to the section 22 by a universal sented t e problem of spreading upon the couplin 24 is a second section 26, forming heel-wall a substantially uniform coating an ang e with its companion section.

of the fibers, which are situated in close'proximity to the inner wall of the plate. The outer portion of the sleeve 44 is threaded at 52 to receive an internally threaded collar 54, which, contactingwith the brush-body, clamps it in place against the plate, The exterior of the collar is also threaded to receive the internally threaded hub of a dished disk 56, the concave side of which is toward the brush. The edge of the disk is shown asl ing somewhat outside the circumference o the plate '46, both of these being within the outer extremities of the brush-fibers which furnish the applyin surface. Movement of the disk along t e sleeve, it being secured at the point to which it is adjusted by a set-screw the hub, allows of a different degreev of compression to be obtained by the contact of the disk. This forces the outer portions ofthe fibers against the plate, without interference with the adjustment by engagement of the disk with the fixed base-portions. The extreme outward adjustment is shown in dotted lines in Fig.

I This permits the effective width of the applying surface to be varied to adapt it to operate over heel-bases of different heights, there remaining in the fibers a capacity to bend laterally on account of the projection of the ends beyond the peripheries of the plate and disk. At the side of the brush where the uncoated portion of the work is without the protection of the ge-disk, this bending is made less than at t e guarded side, because of the greater radial extension of the disk 56. The flexing preferably rather soft, permits the coating substance to be applied without spattermg, and tends to so.that ail-accumulanot be produced. This 1s of especial in! portance at the' lower portion of the base,

1wflzere it contacts with an attached rubben Fixed upon the inner end of the shaft-- fibers 50, there preferably being, however, a

slightseparation to prevent an excessive a plicatlon of the coating substance along this hne. The relation between the disk 58 and the brush may be altered by movement of the bearinge28 upon the bracket 32, this movement ing provided for by the shiftmg of the slot 34 along the screw 30. The edge 60 of the disk is adapted to enter the rand-crease of a shoe S, the heel-base H of which is to be blacked, To this heel-base is shown attached, this occurring prior to the blacking operation, a rubber lift L.

.with the section 22,

The disk 58 acts as a guide or ga e for the work, causing it to be held in tile correct relation to the brush for this to ap ly the coating substance across the side of t 1e baseto the extreme upper portion, at. the same time protecting the upper. The gage-disk also tends to advance the work ast the brush, assisting the operator in this movement. Adjustment of the bracket 32 laterally of the axis of the shaft-section 26 by means of the screw-and-slot connection at 40, 42 alters the relation of the appl ing surface of the brush to the gage-edge o the disk, so that when the latter IS in place in the rand-crease, said brush will act to, the best advantage over the outer surface of the base, giving the desired flexing of the fibers, without putting too much pressure upon these. This position of maximum efficiency may be maintained by this adjustment as the brush wears in use.

The coating substance is supplied from the receptacle 12 to the brush by a rotatable device, including a sleeve 62 fixed upon the shaft 18 and having oppositely extending arms 64, 64. Attached to the extremities of these arms are series of closely placed fingers 66-, the two sets of fingers being staggered with respect to each other, so that they, in combination, operate over a practically continuous line. As the fingers revolve in the direction of the arrow in Fig. 2, they dip into the coating substance in the receptacle, and, upon leaving this, pass throu h the ends of the fibers 50 outside the perip eries of the plate 46 and disk 56. This supplies the necessary amount of the substance to the applying surface of the brush. Because of the angle which the shaft-section 26 car ing the brush forms its rotation, the receiving the coating substance from the fingers diverges from the disk 58. Consequently, while, at the opposite side the disk and brush are closely associated, at the feeding point they are quite widely separated, so the fingers may act upon the brush without interference with the disk. The feeding device has another function. The fingers are curved forwardly in the direction of rotation, and have upon the fibers a combing action which, when they tend to become matted under the pressure of the work against them and the gathering of the coating substance, causes their rearrangement by straightening and separating them. Preferably, the peripheral speeds of the brush and fingers are different, so that the line at which the fingers act angularly about the brush is varied, causing them to operate over the entire applying surface. The sleeve 62 has at its inner side a flange 68, to which is attached a feed-disk 70 provided with a substantially radial rim-portion 72 movable rom which it receives rtion of the brush-fibers the side of the base. To establish the proper overrun, either uppn ed feeding relation between the disks 70' and 58, the, shaft-section 22 is adjustable longitudinally, so that the a plying surface of the rim 60 may be can to approach or retreat from the surface of the disk 7 To rovide for this, the shaft has, outside its ring, collars 74, 74, which may be adjusted upon it to vary the longitudinal position of the shaft. This adjustment occurs without disturbance of the gearing 20 through elongation of the gear-teeth at 76, J

while play in the connections of the couplin 2J4; revents interference with the connecte n the feed the coating substance upo ing surfaceof the disk 70, and therefore the amount supplied to the disk 58, is determined by a stri per-plate 77, which contacts with the f ing portion 72 of the 7 0. The plate is mounted u n a spindle 78 movable lonitudinally t into an opening in the frame and held variably in ition by a set-screw 82. Transversely t ugh the spindle, with its extremities projecting throu h slots 84 in the sleeve, passes a in 86, an between this pin and a collar 88 est upon the sleeve is a helical spring 90. This spring exerts its force to thrust the stripper-plate yieldably toward the feedingiisk. The extent of this move: ment may changed b a collar 92 threaded upon the outer an of the spindle 78, this collar contactin with the sleeve 80. Adjustment of the co ar so alters the relation between the contactsurface of the late 77 and the feeding surface of the di '70 that a film of thecoating substance-of the desired thickness ma be carried upon the latter and transferre to the ap lying surface upon the rim 60. -Yieldabe' scrapers 94, 94 operate u n the outer side of the disk 58,115 in t e atented machine-previously referred to, eeping clean the surface over the shoe-upper. In employing my improved; machine to coat, as with blacking, the heel-base .11 upon the shoe 8', without, having this blacking the upper of the shoe n the attac rubber lift L,- a brush is p aced upon the shaft-section 26, the

width of the applying surface of,the fibers of'which rush approximates the height of the heel-bases to be operated upon'.- To cause the applying surface to not most effectively,

The depth of the layer oflow the surface of the base, ugh asleeve 80 threaded the wall and contact member brushing the black-' ing out smoothly without passing over the line between the base and lift, the disk 56 may be adjusted, this by its contact. with thev outer sides of the fibers, differently compressing them. The operator then,- starting at the unction between the side of the heel and the breast, applies the turning the shoe in the opposite direction to that in which the disk rotates, so that the points of engagement of the rim and the ap lying surface of the brush are gradually s ifted along the heel until the opposite line between the side and breast this travel of the shoe, the blacking from the receptacle 12 by means of the fingers 66 and are straightened by said fingers, while the gage-disk is supplied over' itsside con tacting with the is e of the heel by-the disk 70. Consequent On account of the separation between the brush and the rim '60, the application of the blacking to the side of the heel, along the line of the ledge, is prevented from' bein while at the bottom of the si e, adjacent to the rubber lift, the adjustment of the disk 56 causes the fibers to accurately foland to work the coating out uniformly. During this operation, the upper is effectively shielded by the body of the disk 58. -'The direct connection of the shaft-sections assures a constant speed of rotation and gage-disk, and this actuation, in spite of the an lar relation between the sections, is 'etfecte by simple gearing.
