TILE-PRESS.

Specification of Letters Patent.

Patented Apr. 16, 1912.

Application filed. May 9, 1911. Serial No. 625,987.

To all whom it may concern Be it known that I, SEooNDo GILETTI, citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented new and useful Improvements in Tile-Presses, of which the following is a specification.

This invention relates to machines for making tiles, bricks, mosaics, etc.

The special object of the present invention is to provide a practical, simple, continuously-operating machine for the manufacture of tiles, such as are used in floors, pavements, etc., and particularly to provide a machine in which a number of tiles of various shapes and sizes can be manufactured simultaneously without interrupting the operation of the machine; and to provide means whereby the tile-forming members may be easily removed and others substituted capable of producing other designs.

The invention consists of the parts and the combination and construction of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which Figure 1 is a side elevation of the machine. Fig. 2 is a vertical longitudinal section of the same. Fig. 3 is a front elevation. Fig. 4 is an enlarged sectional detail, showing the plungers and matrix. Fig. 5 is an enlarged detail of a portion of the matrix belt. Fig. 6 illustrates forms of matrix slats in cross section. Fig. 7 illustrates styles of tiles.

A represents an imperforate platen drum, having a polygonal surface, with sprocket grooves 2.

33 are endless chains carrying cross mold-slats4 and passing around the platen drum A and an end idle drum 5. The chains are composed of links pivotally conpairs by the cross pivot rods 6, which fit the grooves 2 in the drums A-5. The several slats 4 are removably and interchangeably connected at their ends to the parallel chains 3 by means of screws 8, Fig.

" 5, to adapt. the machine to different sizes and shapes of tiles, as will be shortly explained. Each of the several slats, which may be of any suitable materlal, is provided with a number of perforations extending entirely through the slats, which perforations are different in the several slats and form matrices in which may be compressed suitable cementitious material, and which take the form in outline similar to the contour of the matrix in each slat. Fig. 7 shows different forms of tiles.

Coacting with the mold or matrix belt formed by the connected slats and chains is a plunger or die-carrying cylinder 9, the periphery of which is provided with a number of longitudinally extending undercut or dovetailed recesses 10 in which are insertible the removable and interchangeable plunger bars 11, secured upon the exposed surface of which areanumber of plungers or male dies 12; those on any single slat being alike, but the dies on successive slats may be different according to the number of different kinds, sizes and shapes of tile it is desired to make at one and the same time.

In arranging the matrix slats 4 with their various molds upon the belt, they are so adjusted successively as to register or coincide with complementary plungers 12 carried by their respective die bars 11 which are inserted upon the cylinder 9. The upper or exposed surfaces of the slats 4 and the plunger-carrying bars 11 are preferably curved in an arc, the radius of which is equal to the radius of the pitch line between the drum A and cylinder 9 so as to form the tiles with parallel upper and lower surfaces.

The material of which the tiles are composed is fed between the cylinders A and 9 through a suitable hopper or feed box 13 which is open on one side, as at 14:, so that an operator may have access and be able to properly distribute the material longitudinally across the matrix slats 4 as they are exposed in the lower portion of the hopper 13 and insure a proper feed of the material into the matrices of the slats 4:. The revolving drum A carries the slats 4L upwardly beneath the coacting cylinder 9, and the plungers 12 coincide with and project into the matrices a sufficient depth to compress the material in the matrices which is supported during compressions upon the platen surfaces of the drum A. As the macontinues movlng,

terial is compressed in the slats the belt carrying the compressed tiles in the matrix openings until they register with ejecting plungers 15, secured upon the upper surface of removable and interchangeable bars 16 carried by a cylinder 17, whihc is supported upon a suitable shaft 18 journaled in the frame of the machine. As each of the matrix slats 4: passes below the drum 17 the compressed tiles are ejected from their respective slats by drum 17 and deposited upon an underneath conveyer 20, by which latter they may be delivered upon a transversely disposed conveyer 21 and carried thence to one side of the machine and discharged at a convenient place.

One of the salient features of the present invention is the provision of the belt in which are mounted the slats 4:, each of which is provided with a number of matrix or mold perforations, and there can be made in the machine at one time as many varieties of tiles as there are polygonal surfaces upon the platen drum A. If drum A has twenty-four of these platen surfaces there can be manufactured at one operation of the machine twenty-four varieties of tiles and as many of each variety as there are perforations in each matrix slat 4. By making the slats 4: of different thicknesses, or, in other words, making the matrix openings of the slats deeper insome slats than in others, tiles of different thicknesses may be manufactured; but in performing this operation it is necessary that the platen surfaces be at corresponding distances radially from the center of the drum 2 for the reason that the pitch diameter or pitch circle in which the sprocket chain forming belts 6 move must be uniform, while the platen surfaces, upon which each slat rests as it moves around with the drum, may be 'varied in distance from the center. For that reason the depth of the slats is shown varied in the diflerent tile making matrices shown in Fig. 6.

Another important feature of the invention is that by a machine of this sort with revolving plungers and horizontally moving matrices I am able to produce tiles whose upper and lower surfaces are in flat parallel planes. This is accomplished, (see Fig. 4:) by forming the exterior operative face 12 of each plunger or die 12 with a curvature of such radius as will produce a surface upon the material in the mold slat one flat plane parallelwith the bottom of the tile which rests against the platen surface.

It is obvious that when a very thin tile is to be manufactured the requisite matrix slat 4 will be made sufliciently deep to receive the necessary volume of tile forming material and the slat will rest upon one of the platen surfaces most distant radially from the center of the drum A. The variation in the distance of the platen surface from the center of the platen drum may be accomplished by attaching to the platen drum surfaces shims a of different thicknesses, Fig. 8.

In order .to break lumps of plastic material as they enter the hopper 13, a rotary brush 24 is mounted above the opening 1& and forces the material against the adjacent wall so that all lumps are destroyed. As the material accumulates on the mold slats passing under the hopper, a scraper 25, arranged adjacent the plungers 12, scrapes off the excess material and keeps the slats clean.

Having thus described my invention, what I claim and desire to secure by Letters-Patent, is i 1. A continuously operating tile press consisting of an endless, slatted belt, the slats of said belt having matrix forming perforations, polygonal drums around which the belt passes, the polygonal faces of the drums supporting successive slats, a rotary plunger cylinder having projecting radial plungers corresponding to and fitting the respective perforations, but not extending clear throughthe perforations, said plunger cylinder disposed contiguous to and perpendicularly above one of said polygonal drums so that each plunger as it enters a perforation will compress the material. to be acted on against a surface of said polygonal drum and said drum will directly resist the pressure of said cylinder, a hopper arranged at the end of the machine outside the belt and in the angle between the plungencylinder and complementary drum, the slats of the belt forming an inclined feed floor for the hopper, and a scraper contiguous to the belt adjacent to the engagement of said plungers with the perforations.
