l'iill -wh'om it may concern I -Be known that I, FREDERICK E. GOLD- sMrrH, a citizen of the United States, and a resident of Middletown, in the county of Butler and St-ate of Ohio, have invented a new and useful "Machine for Coating, of

which the following isla specification.

My invention relates to machines for supplying" coating 'to objects such, for example,

ple and -'e' zonoinica'lly built machine for desinated; n

lecliaracteristics andxadvantages of the invention are hereafter pointed out in detail in connection with the accompanying drawing, which shows in diagrammatic form an exe-mplifying'structure in which thesaid invention i'stmbodied;

p essure rollermounted above thecoating 1' ll; 9, an adjusting shaft; 10, eccentrics thereon mta'tableon thementer 11 12, links connecting the eccentrics with the axis of roller 8; 13, agear rotatably secured -to--the frame and meshing with a gear on the shaft of. the coating roll; 14, an idle pinion int'ernrediate gear 13 and a gear on the shaft ofYt-he pressure roller, 8; 15, 16, links connecting pinion l tradially with the axes of gear 13 and shaft of the pressure roller 8, so as to keep said pinion in mesh with the gears irrespective of the position of the pressure roller. p

The coating roll is rotated from any suitable source of po'wer,'or power maybe applied to gear 13 or shaft of the pressure roller. Rotation of the shaft of coating roll 7, for example, transmits motion to gear 13 thence through -idle pinion 14 to shaft of pressure roller 8. The adjacent surfaces of the coating roll and pressure roller therefo1'e rotate in the same direction, as indicated 'by the arrow. The feed belt and the carry-off belt are simultaneously driven by Specification. of (Letters Patent. ,P Application filed July 26, 1906.

r adj ustabl on a pivotal mounting such'as 29.

In operation, movement of the pitman 25' causes the frame 28 to oscillate in the tub.

The agitator blade moves continuously the coating material, serving to stir and scrape thesame thoroughly .away froni the bottom of .the tub andto keep the material in proper condition for use. The scoop 27per forms," also a similar function. At eac'lf forward stroke the scoop 27 carries a quantity of coating material, and on encountering the lower face of plate-28. (-theplate-antl scoop being shaped so as to cooperateto produce the desired result) this material'issqueezed or squirted out intotrough 20. The coating roll 7 is provided with a bucketed, pervious or absorbent surface and this surface is also preferably compressible or elastic. In rotating the coating roll comes in contact with the coating material in the trough and carries this material up and into contact with the lower surface of the biscuit as they pass, applying to them an even coat of the material. Surplus coating material in trough 20 runs out at the ends and top of the trough back into the tub 21.. It is preferred that the proportions of scoop 27 or its rate of motion be such that a considerable excess of coating material is delivered into the trough over what is immediately used. This insures a copious circulation of coating material and keeps the same in the best condition for use: The shape of the plate 28 and scoop 27 may be widely varied to meet different conditions. By changing the shape of scoop 27 slightly and making its discharge point somewhat higher than that shown in the drawing the plate 28 may sometimes be omitted and the coating material may spill from scoop 27 into trough 20.

The features of this invention, and especially the means ofsupplying coating material to the roll, I believe to be broadly new with me, and I do not limit myself'in any respect to details.

I contemplate any changes which may be made within the spirit and scope of the invention.

IVhat I claim is:

1. In a machine for coating, a coating roll, feed and delivery mechanism, a receptacle for coating material, and a scoop moving be low said mechanism for supplying coating material to the roll.

2. In a machine for coating, a coating roll, a receptacle for coating material, a trough below the roll, and a scoop for carrying coating material from the receptacle and depositing it in the trough.

3. In a machine for coating, a coating roll, a receptacle for coating material, a scoop, means for moving said scoop into and out of the receptacle, and a plate cooperating with the scoop to supply said coating material to the roll.

4. In a machine for coating, a coating roll, a trough below the roll, a receptacle for coating material, a scoop arranged to oscillate in saidreceptacle, and a plate cooperating with the scoop to deposit coating material in the trough.

5. The combination of a coating roll, a tub, a frame mounted to oscillate in the tub, a trough beneath the coating roll, a scoop on the frame, a plate cooperating with the scoop to deposit coating material in the trough, and means for oscillating the frame.

6. The combination of a coating roll, a tub, a frame mounted to oscillate in the tub, a trough beneath the coating roll, a scoop on the frame, an agitator blade on the frame, a plate cooperating with the scoop to deposit coating material in the trough, and means for oscillating the frame.

7. In a coating'machine, the combination of a coating roll, a trough beneaththe roll, a tub below the roll and trough for coating material, a pivotally mounted. plate adjacent to the trough, and an oscillating scoop serving to raise the coating material from the tub and discharge it into the trough by contact with the plate.

8. In a coating machine, the combination, of a coating roll, a trough, a tub for coating material having a cylindrical inner surface, a shaft, a scoop carried by the shaft serving to elevate coating material from the tub and discharge it into the trough, and an agitator carried by the shaft and moving in close proximity to the surface of the tub.

9.'In coating mechanism, the combination of a coating device, a container adapted to retain coating material adjacent to said. device, a reservoir below the coating device, a conveyer for movin coatingmaterial from the reservoir to sai container, and means for raising and'lowering the reservoir to clear it from said coating device and conveyer for placement and replacement.

In'testimony whereof I have affixed my signature in the presence of two witnesses.
