APPARATUS FOR MAKING TILES.

Specification of Letters Patent.

Application filed July 2, 1913. Serial No. 777,033.

T 0 all whom it may concern Be it known that I, ARTHUR I-InNnoz, manufacturer, a citizen of the Kingdom of Belgium, and resident of 335 Avenue Louise, Brussels, Belgium, have invented certain new and useful Improvements in Apparatus for Making 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, refer ones being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to improvements in apparatus for the manufacture of patterned or fancy tiles, in which the tile under treatment is carried by a circular table having an intermittent rotary motion to bring the tile successively opposite suitable devices for applying color, pressing the tile and other operations necessary for making the tile.

Hitherto in machines for manufacturing patterned tiles, the colors were fed simultaneously through a stencil or patterned plate. According to the present invention, however, the tile is brought successively opposite a number of separate color feeding devices, each of which sets the design in one particular color or material only, the tile being passed on by the rotation of the table to the further devices treating it. A. greater eliiciency andaccuracy of pattern is thereby obtained which is furthered by the improved color distributing devices according to the present invention.

The invention is more particularly. de scribed with reference to the accompanying drawings in which: 1

Figure 1 is a plan view of the whole apparatus. In this view some of the devices constituting the apparatus are in section. The part II is a section on O-P'of Fig. 3. The part III is a section on Q,R of Fig. 3, the part IV is a section on ST of Fig. 2; Fig. 2 is a section on an enlarged scale on ABE CC of Fig. 1; Fig. 3 is a section on an enlarged scale on E-F of Fig. 1; Fig. 1 is a section on an enlarged scale on Gr-II of Fig. 1; Fig. 5 is a section on an enlarged scale on M-N of Fig. 1. Fig. 6 illustrates the counter pattern.

A revolving plate composed of segments or sections 1 supported by rollers 2 and 3 mounted on a frame f, is provided with internal teeth and is periodically'rotated a certain distance by a toothed sector 5 driven by bevel gearing from the shaft d5. Each of these sections 1 has a rectangular aperture in which is inserted a frame? carrying twin' molds 6. Under this aperture a sliding member 8 adapted to be operated by a handle 9, is arranged. The intermittent rotation of the plate successively brings each. pair of molds 6 to the place where the operations for making the tiles: are carried out, namely at I the placing of the pattern members or stencils which act as means to separate the various colors; at II, III, IV, V and VI, the insertion of the various colors (the apparatus shown thus enables tiles to'be made comprising five different colors not including the foundationor body color) at VII the stencil members are removed, at VII, the molds are filled upwith body color (filling up mass) at VIII the tiles are pressed and, at VIII removed from the molds. The stencil members, withdrawn by hand at VII, are placed on a belt conveyer 10 which brings them to I, ready to be used again. The molds thus provided at I with-their stencils are brought to II and then successively to III, IV, V and VI. In each of these positions, they are automatically fed with a differently colored material from a hopper 11 closed by two sliding doors 12 and 13. Each of these slides 12 and 13 is controlled mechanically, in such a way that when one of them is opened the other is closed, and the result is, that when the upper slide 12 is open, the material falls on to the slide 13 and when the latter is subsequently opened, the quantity of material thus predetermined lying between 12 and 13 falls on to a sieve 14. This sieve is fixed to a framework 15 which supports all the sieves and is itself carried by arms 16 on a vertical shaft 17;

cams l8 and 19, operated by shaft 20, act alternately on the ends of the framework 15, so as to impart to it an oscillatory motion which aids the sieving action. Springs arranged at 21 increase the oscillations producing counter oscillations. Beneath each of these sieves a counter pattern 22 (Fig. 6) is arranged and is mechanically operated, so as to place itself above the mold (Fig. 3) before the coloring matter falls through the sieve, and to be then withdrawn and afterward to be turned (Fig. 2), so as to discharge into a suitable receptacle 23 the excess of colored material not utilized. This Patented July 25, 1916.

movement of the counter pattern may be operated by any suitable mechanical combination. Figs. 2 and 4 show one of these possible combinations by way of example. Fig. 2 represents the parts when the counter pattern 22 has completely turned, at the mober 26. These two pivots 25 pass through the ends of a fork 28 hinged at 29 to a lever pivoted at 30. This lever carries at its end a cam slot 32, which engages a stud 31 fiXed on a plate 33 rotated by a motor shaft 24. It is evident that the rotation of the shaft 24 causes a displacement of the counter pattern from the position illustrated in Fig. 2 to that illustrated in Fig. 3 and vice versa.

2 In order that the counter pattern may remain, during the time necessary for the dis charge of the material in the mold, in the position illustrated in' Fig. 3, the cam slot 32 has a circular part concentric with the wheel 33.

The rotation of the counter pattern 22 at the end of its path, which is necessary to discharge the eXcess of material into the receptacle 23, is obtained by the action of'the rack 34 with which there engages a toothed wheel 27 keyed on one of the pivots 25, when the counter pattern is completely drawn back toward the rear (Fig. 4). The rack 34 is fixed to a lever 35, which is movable around an axis 53 fixed to a support 56. A stud 36 fixed on the plate 33 at this moment meets the lever 35. The rotation of the plate then causes the movement of the lever 35 around its pivot and thus lowers the rack 34. The movement continues till the stud 36 is no longer in contact withthe lever 35 as shown in Fig. 2. The lever 35 thus becomes free when the rack 34, under the action of the spring 37, again takes up the position shown in Fig. 4 and places the counter pattern in its original position. The stud 31 is displaced from the position represented in Fig. 4 to that in Fig. 2 in the circular part of the cam slot 32 and thus it has not caused a displacement of the. lever pivoted at 30. The movement of this lever thus only begins when the stud 31 has reached the end of the circular part of the cam slot 322'. e. somewhat later than the position shown in Fig. 2.

In the modification shown in the drawing, the shaft 24 also actuates the governing means of the sliding doors 12 and 13, which in this example consist of two rods 47 and 54 guided in supports 48 and operated by two arms 49 and 55 keyed on the shaft 50. When the arm 49 leaves the rod 47, a spring 51 again moves the door 12 to its original position. One end of the spring 51 presses against one of the supports 48 and the other 'end against a projection 52 on the rod 47. i The door 13 is operated in a similar manner.

' VII where the stencil is removed .by hand.

The mold then passes beneath a bottomless trough 39 containing body (filling) material, the lower walls of which bear against the upper side of the, revolving plate; a portion of this material then enters the mold and completes the filling of it. Portions of the colored material which may have been able to fall out around the mold during the foregoing operations are brought into this mold by means of inclined plates 40. The mold thus completely filled is brought to the point VIII to the press 41, the successive operations of the various members of which are controlled by the usual cam members 42 on a continuously rotating shaft. Finally the pressed tile reaches VIII the slide piece 8 is drawn outwardly either by hand or mechanically by means of a suitable mechanism (not shown) and the tile being no longer supported, falls by reason of its own weight-or is ejected from the mold by the usual plunger mechanism 43 on to a conveyer 44 which carries it to the furnace or to the drying apparatus, according to the nature of the materials employed. In order that these various operations may take place with precision, it is necessary to lock the revolving plate each time it has been moved a predetermined distance to bring a tile opposite a mechanism to operate upon it. For this object, locking members (not shown), controlled by the principal motor shaft 45, are used, which enter notches 46 in the plate.
