FREDERICK E. GOIIDSMITH, OF HAMILTON, OHIO, ASSIGNQR TO' THE CERAMIC MACHINERYCOMPANY, OI HAMILTON, OHIO.

MACHINE FOR COATING TILES, 85o.

Specification of Letters Patent.

Patented Aug. 20, 1912.

Application filed December 2, 1908. Serial No. 465,589.

To all whom it may concern:

Be it known that I, FREDERICK E. Gono- SMITH, citizen of the United States, residing at Hamilton,'-Butler county, Ohio, have invented certain new and useful Improvements in Machines for Coating Tiles, &c.,

of which the following is a specification.

.This invention, pertaining to machines for coating tiles 620. will be readily under:

stood from the 'following'description taken in connection with the accompanying drawvat 4 by being fed thereinto through supply opening 5, the level of the, coating material in the vat being determined by the height of adjustable end-gate 6. The tile then moves forward over roll 7, suppliedwith coating material from the overflow at endgate 6 and then passes over air-blast pipe 8 to intermediate apron 9, of suflicient length to satisfactorily dry the tile, the tile then passing over mottling rolls l0 and 11 more or less immersed in coating material in tank 12 supplied through opening 13 and having its level regulated by end-gate 14, the tile then being carried away on discharge apron 15.

All the rolls and aprons are to be continuously driven by power, -The rolls illus trated, with the exception of roll 10, are of the known loose eccentric foraminous shell type, in which type of rolls the coating material carried up in the first lunar space between the .core and the shell becomes expressed upwardly through the shell and delivered to the lower face. of the tile, the

effect is to be produced upon thetile.

capable in dealing with certain classes of coating material; of yielding a thicker coats ing than could otherwise be done with that I material. hen the-coating rolls 2 and 3 act after'the manner of true coating rolls,

andregardless of whether there be one or more of these rolls, end-gate 6 will be com paratively low and the rolls in vat 4 be but partially immersed.

The coating produced by'rolls 2 and 3, owing to the rather heavy character of the work done by them, ,is quite apt, with some characters of c'oatingmaterial, to leave the work-. more or less rough or pitted. Roll 7 acts as afinishing roll to cure defects." It is less liberally supplied with coating material than rolls 2 and 3 and its covering should be finer. As the rear corner of the tile leaves finishing roll 7 there may be, in some cases, a tendencyfor the corner to accu1nulate an excess amount-of coating material. The air-pipe 8, in addition to the general drying ofthe surface of the tile as it passes over it, serves to blow rearward on the surplus coating material in'quest'on and cause that surplus to 1% taken up by'roll 7 or, to

put it in other words, the air-blast, in connection with the rear corner of the tile, resists the delivery'of an excess quantity of coating material by the roll.

The balance of the mechanism is to be employed only in case a secondary or mottling Rolls 10 and 11 produce such spotting or mottling effect as is desired. One .mottling roll alone will accomplish this result but the elfect will be mechanical, mathematical and unbe'autiful when a number of the mottled tiles are placed in association. In the present case rolls 1 0 and 11, regardless of whether, their mottling elements arealike or diiferent, are

different in diameters and construction, roll 10 being an ordinary mottling roll, while roll'll is of the eccentric loose-shell type, the

shell being free to swing and turn and slip more or less independent of its core. result is that the mottling produced by the conjoint action of the two mottling rolls is The rolls in vat 4, no matter how many there may be of them, are to be abandoned as coating rolls and, if employed, are to be employed simply as carrying agents. Endgate .6 is to be raised until the level of the coating material in vat 4 will be constantly maintained above the level of the to s of the rolls in the vat. The tile then sli es, so to speak, over alake of the coating material and takes on the coating by reason of direct contact with the material in the vat, the rolls in the vat, or any substitute for those rolls, acting as mere carriers to advance the tile over the coating material.
