AUGUST W. IIOCII, OF CINCINNATI, OHIO, AND CHARLES F. KOCII, OF COVINGTON, KENTUCKY.

TILE-DIPPING MACHINE.

EiPECIFICATION forming part of Letters Patent No. 642,135, dated January 30, 1906. Application filed April 8, 1899. Serial No. 712,221. (No model.)

To aZZ whom, it may concern:

Be it known that we, AUGUST 1V. KOCH, re-

siding at Cincinnati, in the county of I'Iamilton and State of Ohio, and CHARLES F. Kocn, residing at Covington, in the county of Kenton and State of Kentucky, citizens of the United States, have invented certain new and useful Improvements in Tile-Dipping Machines; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to certain improvements in machines for applying color, glaze, or the like to tiles and other articles before firing; and the object of the invention is to provide a machine of this character which' shall be simple and inexpensive in construction and having means for mechanically feeding the tiles or other articles in a substantially continuous manner, so that the operation of the machine is improved and its out put increased and the labor in supplying the articles to and removing them from the machine is lessened.

The invention consists in certain novel features of construction, combination, and arrangement of the several parts of the improved machine whereby certain important advantages are attained and the device is made simpler, cheaper, and otherwise better adapted and more convenient for use than various other coloring and glazing devices heretofore employed, all as will be hereinafter fully set forth.

The novel features of the invention will be carefully definedin the claims.

In the accompanying drawings, which serve to illustrate our invention, Figure 1 is a side elevation showing a machine constructed accordingto our invention, and Fig. 2 is a plan view of the same. Fig. 3 is a vertical sectional view taken transversely through the machine in the plane indicated by line a; a: in Fig. 2.

In the views, 1 indicates the frame of the machine, having at its ends supporting-legs and formed with a widened central part 2.

3 indicates the feed-trough,preferably hiade inclined and having raised sides to facilitate the feeding of the tiles or other articles placed on it to the machine. The feed-trough is located at one end of the frame 1, and at the other end thereof is arranged a delivery-tablo 4 to receive the articles after passing through the machine.

At one end of the frame 1, near the feedtrough 3, is arranged a transverse drivingshaft 5, having tight and loose pulleys 6, so that the machine may be operated by a belt from any convenient source of power, and said shaft 5 is coupled to drive, by means of toothed gears 7, a shaft 8, parallel to it and having at its central part, between the side bars of which the frame 1 is formed, a wood roll or pulley 9, over which passes the bight of an endless carrying-apron 10, extending lengthwise of the frame between the side bars thereof and supported on idler-rolls 12,held on shafts 11 transverse of the frame. The idlers 12 are arranged in two groups or series of three each, one series at each end of the central wider part 2 of the frame, and said idlers serve to sustain the central part of the endless apron 10, the last idler of the rearmost series receiving the bight of the apron. The shaft 5 also carries, outside the frame, a pulley 13, over which passes a belt 14, extending over a pulley 15 on a shaft 16, journaled transversely of the central wider part 2 of the frame and geared, by means of bevel-gears 17 at its central part, to a vertical shaft 18, which extends down into a cone-shaped colortub 19, arranged beneath the wider part 2 of the frame and adapted to hold the coloring or other material in liquid form. The shaft 18 has blades 20 within the tub 19 to agitate or stir the liquid therein to maintain the desired consistency thereof. The shaft 16 is also provided with a pulley 21, over which extends a belt 22, leading around a pulley on a pumpshaft 23, journaled transversely beneath the frame and serving to operate a centrifugal pumping device 24, to which the liquid from the tub 19 is supplied by means of a pipe 25. A pipe 26 leads from the pump 24 abovethe frame, extending up along one of the uprights or standards 28 of a yoke which extends across the wider part of the frame, and said pipe connects with a flexible hose 29, on the end yoke to deliver its spray upon the tiles or other articles carried through the machine beneath said yoke upon the endless apron 10.

A sheet-metal hood or guard 30 of conical form is arranged beneath the spray-nozzle 27 over the shaft 18 and gears 17, so as to protect the same and prevent clogging of the gears with the coloring or other matter, the conical sides of said hood serving to return the liquid back into the tub 19. The lower part of the hood 30 is by preference formed with a circumferential depression or hollow 31, having in its bottom apertures 32, acting as-a strainer to prevent particles of foreign matter from passing into the tub.

In operation the tiles or other articles to be coated are placed upon the feeding-trough 3 and pushed successively therefrom onto the endless carrier or apron 10, as indicated at. T in Figs. 1 and 2, the upper run of the apron being substantially level with said trough to facilitate the feeding of the articles. The articles are carried by the apron along the frame beneath the yoke at the wider part thereof and are given the desired coat of coloringmatter, glaze, or the like in the form of a fine spray by means of the nozzle 27, which by reason of the flexible hose-section 29 is capable of adjustment to deliver its spray at any desired angle, so that the color may be regulated at will. The articles after being coated are delivered by the apron to the delivery-table 4, which is preferably set slightly below the plane of the upper run of said apron as seen in Fig. 1, so as to facilitate the delivery of the articles.

From the above description it will be seen that the machine constructed according to our invention is of an extremely simple and inexpensive nature and is especially well adapted for use, since its permits of feeding the articles to be coated to the machine in a continuous manner, so that stopping of the machine to apply and take off each article is obviated and the articles are evenly and uniformly coated. the above description that the machine is capable of considerable modification without material departure from the principles and spirit of the invention, and for this reason we do not wish to be understood as limiting ourselves to the precise form and arrangement of the several parts herein set forth.

Having thus described our invention, we claim- 1. In a machine of the character described, the combination of a frame, an endless carrier extended thereon, a nozzle, a reservoir, a pump, a pipe extended between the reservoir and the pump and arranged to supply color- I ing-matter, glaze or the like to the pump from the reservoir, and a flexible connection between the pump and the nozzle for supplying coloring-matter, glaze or the like from the pump to the nozzle while permitting adjustment of the nozzle in directing the discharged spray upon the articles held by the carrier, substantially as set forth.

2. In a machine of the character described, the combination of a frame, a carrier thereon, a nozzle arranged above the carrier in position to discharge coloring-matter, glaze or the like in finely-divided form to the articles held by the carrier, a reservoir for containing a supply of said coloring-matter, glaze or the like, said reservoir being arranged beneath the carrier in position to receive the surplus coloring-matter, glaze or the like from the nozzle, a shaft extended across the frame above the reservoir, an agitator-shaft having an agitator for stirring the material in the reservoir, gearing between said shafts, a shield arranged over the gears and also extended over the reservoir, and a strainer carried by the lower edge of said shield to strain the material discharged thereon from the nozzle,substantially as set forth.

3. In a machine of the character described, the combination of a frame, a carrier extended thereon, a nozzle arranged abovethe carrier in position to discharge a spray of coloringmatter, glaze or the like in finely-divided form to the articles held by the carrier, a reservoir arranged beneath the carrier in position to receive the surplus coloring-matter, glaze or the like from the nozzle, and means for drawing the coloring-matter, glaze or the like from said reservoir and forcing the same through said nozzle, substantially as set forth.
