COUNTERPATTERN USED IN THE MANUFACTURE OF TILES.

Application filed April 16, 1923. Serial No. (532,462.

To aZZ whom it may concern:

Be it known that I, ARTHUR HnNnoz, a citizen of the Kingdom of Belgium, and resident of Brussels, Belgium, have invented certain new and useful Improvements in Counterpatterns Used in the Manufacture of Tiles; and I do hereby 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 letters or figures of reference marked therein, which form a part of this specification.

The present invention relates to counterpatterns used in the manufacture of tiles with encrusted designs made of sandstone, ceramic ware or other analogous materials.

In this process of manufacture, the separation in the stencil-frame of the different coloured materials composing the design, is regulated by compartments which follow the lines of the design which it is desired to make.

In order to regulate the admission of each colour which should fill certain compartments and not others, there is applied each time on the stencil-frame a counter pattern, whose openings are arranged in such a manner as to coincide only with the particular compartments to be filled and which closes the other parts of the stencil.

Counter-patterns are known in which the openings for the passage of any one colour have approximately the same area as the corresponding compartments of the stencil which are thus left free and wide open. These counter-patterns have the serious disadvantage that at the points where the stencil openings are relatively large, the colour is irregularly distributed.

Other counter-patterns are likewise known, in which the bottom wall is provided with a series of openings of the same shape and size; such construction present ing the objection that the openings are filled uniformly regardless of the shape of the stencil. In the small parts of the latter, these openings are useless and only complicate the construction of the counterpattern; and in certain cases, particularly when thick colours are used, or those which have a tendency to conglomerate, these openings become a hindrance in that they needlessly impede the delivery of the material.

To overcome these defects, and to permit a ready and uniform distribution of the colour at the bottom of the mould, regardless of the complexity of the design, without obstructing any part of the colour passages, the counter-pattern according to my invention is provided with openings whose shapes and dimensions have three characteristics V 1. At the points where the area of the compartment is large, the circular openings have relatively large diameters to enable the colour to fall freely upon the bottom of openings will have a smaller diameter,

while still following the outline of the compartments, the area of the openings being just sufficient to permit the passage of the heavy material therethrough.

The drawing accompanying the present specification represents for the sake of example one constructional form of the in vention.

Figure 1 is a View of the in plan, and

Figure 2 is a cross-section of Figure 1 on the line AB.

Figure 3 is a plan view of a partitioned stencil corresponding to the counter'pattern shown, the compartments which should be filled with some one particular colour being shaded with dotted lines.

Figure 4 is a sectional perspective View, on line A-B, Figure 1, showing the different parts in assembled relation.

In these drawings the pattern or stencil is constituted by a frame '1 which is divided into different compartments 2 by thin vertical walls 3 which follow all the outlines of the design.

countenpattern definite .3. At the points where the design has a The counter-pattern 4 is placed in this stencil, the two being held in their relative positions by the mould (not shown), in which the tile is manufactured. The continuous edge 5 of the counter-pattern 41 rests on the upper face of the mould.

The holes 6' of suitable shape are formed through the counter-pattern in such a way as to allow the colour to pass across them.

in order to be emptied into the corresponding partitions 2 of the pattern.

The openings provided in the counterpattern have variable dimensions, so as to conform them to the size, shape and outline of the stencil compartments. Hence, the passage of the colours is not hindered at'any point and their distribution takes place uniformly in thedifierent compartments. The counter-pattern according to this construction has openings of greater diameter than is absolutely necessary to per-- mit the passage of heavy material at the points where the compartments 2 (l igure 3) are located, so as to enable the colour to fall to the bottom of the mould withoutencountering the difficulties or obstructions to its distribution, the openings serving merely to guide and uniformly distribute the material. I

On the other hand, at the points where the contours of thede sign are COH'lPllCElttit, and where, for that reason, the distribution of the colours is extremely difficult, the openings have a smaller diameter which conforms approximately to that absolutely necessary to allow the heavy material to pass and to feed it in sutficient quantity to the different parts of the design.

In the" case of compartments such those indicatedat 2 which are of small size and, where there is no danger of unequal distributionof the colouring material, the openings formed in the counter-pattern have exactly the same shapeand size as. the compartments. i

It'goes without saying that the dimensions and shapes of the openings do not deeend solely upon the form of the design,

but equally upon thenatureheavy or thin of the colouring material.

Fig. 4c shows diagrammatically the elements specified above in working position.

in this figure, the counter-pattern 4 is placed on the work table 7 and masks the stencil 1, blocking the compa 'tments of the latter which must not be filled, while leaving the colour entirely free to pass through the openings 6 in order to fall to the bot tom of the corresponding compartments 2 and? of the stencil.

The improved counter-pattern can be used in any sort of process for the manufacture of ceramic tiles with encrusted designs, either by hand or by machine.

I claimas my invention:

1. In apparatus for the manufacture of ceramic tiles with encrusted designs in colour, the combination, with a stencil or pattern member having partitions forming compartments torecelve material of different colours, of a counter-pattern whereon the colouring material is deposited enibodying a plate formed with openings located directly above said compartments; said openings being of three different types comprising holes of relatively large diameter situated over compartments of coinparatively large area, elongated apertures situated over comparatively narrow can partments and conforming exactly to the outline thereof, and relatively small holes supplemental to the first-named holes for filling in complicated areas of-the design.

In apparatus for the manufacture of ceramic tiles with encrusted designs in colour, the COlTlblDtltlOIl, with a stencil or patterninember having partitions forming compartn'ients to receive material of ditferent colours, of a counter-pattern where on the colouring material is deposited enibodyinga plate formed with openings located directly above said compartments;

saidopenings comprising holes of relati ly large diameter situated over compartments of comparatively large area, and relatively small holes supplemental to the first-named holes for filling in complicated areas of the design.

In testimony whereof I afl ix my signature in presence of two witnesses.
