Application led June 14, 1913. Serial No. 773,723.

To all whom z't may concern.'

Be it known that I, FRANK B. YINGLING, a citizen of the United States, and resident of Hamilton, county of Butler, State of Ohio, have invented certain new and useful Improvements in Machines for Coating Tile, Terra-Cotta, &c., of which the following is a specification.

The present invention relates to an improvement in machines for applying to desired surfaces of ceramic articles, and particularly tile, terra cotta or brick, a liquid coating which by a subsequent burning operation will be converted into a hard glasslike material. The composition of the liquid coating employed is varied according to the color desired for the finished glazed surfac'e, the character of the material from which the article to be coated is formed, etc.

In the accompanying drawings, Figure 1 is a plan view of an embodiment of the invention, the several parts being shown more or less diagrammatically; Fig. 2 is a side elevation. partly in section, of the machine; Fig. 3 is a transverse sectional view substantially on the line 3-3 of Fig. 2; Figs. 4 and la are detail views; Fig. 5 is a side elevation, more or less digrammatic, illustrating a modification of the invention; Fig. 6 is a transverse sectional view of the same; Fig. -7

is a detail view of one of the grippers shown` in Figs. 1 to 3; Fig. 8 is a detail sectional viewA on an enlarged scale of a part of the means for driving one of the ftrimming wheels; Fig. 9 is a detail showing a part of the nozzle adjusting devices detached; Fig. 10 is a detail view.

Referring to the drawings, it -will be seen thatthe machine comprises a suitable supporting frame within which are supported one or more receptacles l for holding liquid coating or glaze forming material. Only one of such receptacles is illustrated in the drawings. It is frequently necessary or desirable to apply two or more layers of coating material to the surfaces to be glazed and therefore the machine preferably includes at least two receptacles 1, each being pro-v vided with means such as hereinafter` described for conveying the coatmg fluid to the surfaces to be treated. For example if bricks formed of relatively coarse clay` are to be treated a finish coating of finer clay or enamel may be firstapplied by one of said sets of coating means and a second coating of glaze material applied to the samesurfaces by the second set of coating means.

The receptacle 1 is mounted to rotate about a vertical axis and for this purposel the bottom 2 thereof is suitably geared to a power mechanism, as in Fig. 6 for example. In the receptacle is suitably supported a tube 4 which is inclined as shown and has its lower en'd deflected or bent laterally so that the action of centrifugal force produced by rotating the receptacle 1 wil-l cause the liquid therein contained to enter and" flow upwardly through said tube. The tube 4 has its upper end connected by a flexible conduit 7 with a nozzle or` coating device 6 that is supported by the framework of the machine in a manner to be hereinafter more particularly described. The nozzle or coating device 6y is preferably made in the form shown, being substantially rectangular in .Cross section and having the outlet or discharge opening 6 formed in its top surface with its greatest dimension extending parallel to the direction in which the articles to be treated are moved thereover.

Beneath themember 6 of the coating devices is arranged a drain pan or basin for receiving the surplus coating liquid flowing from the opening 6 and not adhering to the articles to be coated, said drain `pan being connected with the receptacle l by a return pipe or conduit 8.'l

By the construction described it will be seen that by rotating the receptacle 1 a continuous circulation of the coating liquid will be maintained through said receptacle and the nozzle 6. The particular construction of means hereinbefore described for effecting circulation of the coating liquid. is not an essential part of the present invention and no claim is herein made thereto. It will be evident that any means for effecting a continuous flow of coating liquid from a suitable receptacle to a distributing nozzle .may 'be employed instead of the one described, which however has been found to operate satisfactorily.

The articles to be treated are successively moved across the opening of the nozzle of loo the coating devices with the surfaces thereof .which are to be coated in the path ofthe liquid flowing from said nozzle. As shown, in Figs. 1 to 3 the conveying means comprises two endless chains 10 Which are supported by sprockets carried by verticallil shaftsk kmounted in I' suitable bearings and housings adjacent opposite ends of the machine frame, said chains being shown as guided by channel bars 5. lt will be seen that each link of the chain carries a gripping plate or member 11 which is yieldingly y pressed outward by a suitable spring and that each link is provided with

guide rolls

12, 13, engaging flanges on the guiding beams 5. The gripping members 11 of the two'chains are arranged in alinement and so spaced that each pair thereof is adapted to securely grip the article to be treated, as it is'passed intothe space separating the members of the conveyer and the parts are so related that the article will project below said grippers and be maintained in a horizontal position. While the machine is adapted for coating various forms of articles, the drawing illustrates it as'employed for coating brick, but in this description the term brick is not intended to be understood as limited to an article of the exact form illustrated. y

The vertical shafts of the driving sprocketslt are connected by bevel gears with a shaft v15 adapted to be connected with an alined drivingshaft by a clutch 16, said driving shaft having secured thereon a power pulley 17V. Manipulation of the clutch 16 is eected by a'rock shaft 18 extending longitudinally of the machine and provided with an operating handle or lever 19. To maintain thel desired tautness of the chains 10 of the conveyer, the idler sprockets therefor are subjected to the action of suitable springs 21.

As shown, the brick are introduced between the gripping members of the conveyer by means comprising two

endless belts

22, 23, between which may be arranged a rotating brush 24C adapted'to clean the lower surface ofthe brick to which the liquid coating is to be applied, and a generally similar discharge belt 25 is provided to receive the coated brick as they are released by the grippers 11. rlhe discharge belt 25 is arranged in a plane slightly below that of the lower surfaces of the bricks while passing the coating devices so that the bricks are delivered from the grippers without danger of being damaged by being dragged over the belt. f the belt 25 should become sufficiently damp from the moisture remaining on the coated sur faces of the bricks it might cause the enamel or glaze coating to adhere thereto more firmly than to the brick, thus drawing said coating from the brick.4 To avoid this a heating device 26 may be provided so that the belt will be maintained in proper dry condition. i

ln coating certain kinds of brick, it is necessary to meisten or dampen the surface to be coated before applying the liquid glaze thereto and for this purpose a roll 27 supincassi ported to turn in a pan 28 containing water may be provided between the feed belt 23 and the coating devices, said roll being so positioned and of such contour that it will contact with the surfaces of the bricks to be coated as they pass thereover.

Experience with machines of this charactruly horizontal position while being coated .i

and during the coating operation are engaged at points above the surfaces to which the coating is applied. lf the bricks are held in an inclined position when the coating ris applied, the liquid will flow toward the lower end thereof and thus the coating will not be of uniform thickness over the entire surface treated. lt is also important that the coating be applied only to the lower surfaces of the bricks and not allowed to flow upwardly lover the sides. For this purpose the outlet of the nozzle 6 is as shown preferably made of less width than the brick and the liquid is caused to flow upwardly and then laterally across the lower surface of the brick. To insure however that any of the coating which may flow upward at the edges of and adhere to the sides of the brick shall be removed, the machine is provided with cutting or grinding devices adapted to yieldably contact with the sides of a brick after the same has passed the coating devices. As shown these cutters are formed as bevel disks 30 arranged at an angle to the line of travel of the bricks and supported by shafts 32, which are supported in pivotally mounted bearings 31. Suitable springs are provided to normally force said disks 30 in to position to contact with the sides of a brick. A guide roll 33 is connected with "each of said shaft bearings and adapted to Contact with the brick to properly position the cutting disk relative thereto.

The means referred to for supporting and actuating the cutters 30 is shown more or less conventionally in Figs. 1 and at and a part thereof in enlarged sectional detail in Fig. 8. As shown in the latter the shaft 32 is made in two sections connected by a universal joint 32a and the sprocket 32b at the outer end of said shaft is connected by a chain with a sprocket on a counter-shaft 32c journaled in suitable bearings on the frame-work of the machine and itself driven through suitable sprockets and a chain 15a will e which may have adhered to the sides of the ing 3l r the cutters 30 to maintain said cutters 1n proper contact with-the brickV passin between them. Such cuttingfdevices ectually remove any of the coatlng brick without damaging the brick, and by employing such cutting means it is not essential that the discharge opening'of the nozzle be .of less width than the brick.

In order that the coating devices may be readily cleaned, the frame by vwhich the nozzle and drain or overiow pan arev sup' ported is mounted so that it may be adjusted vertically. As shown, said frame is lcarried b two arms 34 which are journaled upon a rock shaft 35 mounted in suitable bearings on the main frame and said shaft is provided at one end with an operating" handle 36. A counter balance spring 37 is arranged to bear against an arm 35a depending from the shaft 35. The spring 3T is supported by a rod or bolt 37 projecting from a member of the main supporting frame and passing through an opening 1n.

said arm 35a. A nut or head at the outer end of thisl rod forms an abutment for the spring 37. To insure that the nozzle will be maintained in the desired horizontal relation to the brick, and the endless conveyer by which the brick are moved over the coating mechanism, a link 40 is pivotally connected with a portion of the nozzle supporting frame and the main frame of the machine. The distance between the pivotal centers of the arms 34 and link 40 being the same, insures parallel motion of the members and the nozzle is maintained horizontal.l in.l elther its upper or lower position and adjustable stops are provided forcoperating with the handle 36 to hold Ithe nozzle in either of said positions. As shown in Fig. l0, two lugs are suitably connected with the lever 36 and with these are adapted to co operate two pivotally mounted manuallyl adjustable stops 36a, 36" b'y which the lever and liquid nozzle may be held in either- 'of the two positions referred to.

The channel beams 5, by which the chains 10 are supported and guided are adapted to be, adjusted transversely relative to each other to adapt the machine for Coating arti* cles of different widths. As shown saidl beams are` engaged by suitably threaded shaft 45 that is provided at one

end shafts

41, 42, mounted on the frame of the machine and having bevel pinions 43, 44-

with whichv engage similar pinions "on a with la wheel 46by which it may be turned. In Figs. 5 and 6 there is illustrated a slightly modified form of the invention which is designed to prevent the coated surface of the bricks from coming' in contact with any part of the mechanism. With certain classes of brick there is a possibilityof the appearance of the coated surface being marred or the brick slightly damaged by V'Contact with'the delivery belt 25; and the embodiment of the invention shown in Figs.

stantially elliptical form in side elevation and composedV of suitably shaped channel bars. The Wheels 52 of the trucks run in the channels in the bars forming the track and each truck comprises two elastic faced clamping members 53 and an intermediate spring 54 which acts to separate said members so that a brick may be' readily inserted in or removed from the truck.

Guide members 55 extending throughout v the greater portion of the length of the track 50 coperate with compression rolls 56 to hold the members 53 in close engagement with the brick inserted between them.

In usin the machine the brick are successively lnserted in the trucks positioned about the point A in Fig. 5 and the trucks manually moved along the track to the right,

between the compression guides 55 and finto j i' 'l the lower vrun way of the track 50 contacting one with the other and are forced over the 10 coating devices by the action lof the rolls 58. -Each truck is provided at one end with a partition which acts to separate the brick in one truck from that in the following or prev .y y

ceding one in the same mannerl and for the purpose that the plates 29 are employed with the machine illustrated in Figs. 1 to 3. When As shown several trucks are assembled in a truck has been thus moved past the coating s The machine may of course be provided with means such as previously described for removing any ofthe coating whichmay-fiow up on and adhere to the sides of the brick.v

The members of the track 50 are adapted 'devices andinto the upper run way of the to be adjustedtoward and from each other by means of suitably threaded shafts and a citrolling hand wheel G3, so that the machine is adapted for coating bricks of different thickness.

In the accompanying drawings most of the parts are shown more or less diagrammatically as there can manifestly be many heavier or thicker coating. ln view, how-` ever, of the size of the parts, it has been deemed inadvisable to illustrate more than one set of such coating devices in the accompanying drawings.

As hereinbefore noted, the devices particularly illustrated and hereinbefore described are designed for coating flat surfaces, but it will be evident that the invention can be readily embodied in a form adapted to coat irregular surfaces such as are known to the t 'ade as trimmings, moldings, cap and base and relief designs.
