TILE-MOLDING MACHINE.

To all whom it may concern:

Be it known that we, TERRENCE W. Cos- TELLO and JOHN W. HOUSTON, citizens of the United States, residing at Conception J unction, in the county of Nodaway and State of Missouri, have invented certain new and useful Improvements in Tile Molding Machines, of which the following is a specification.

This invention relates to certain new and useful improvements in machines for making tile, the object being to provide a machine which can be either operated by hand or power.

Another object of our invention is to provide a tile machine with separable mold sections, one of which is so mounted that it can be readily lifted with the pallet board, so as to remove the tiles after being molded.

Another object of our invention is to provide means for withdrawing the cores, so that the molded tiles can be readily removed without any danger of injuring the same.

Another object of our invention is to provide very novel means for tamping the substance for forming the tile.

Another object of our invention is to provide guide members for the tampers, so that they will be held in a vertical position as they are forced downwardly.

Another object of our invention is to provide very novel means for vibrating the hopper so that the substance therein will drop into the molds around the cores.

A further object of our invention is to provide means for locking the hopper in position over the molded sections.

These objects are obtained by the novel arrangement and construction of parts hereinafter fully described and shown in the accompanying drawings, in which Figure 1, is a perspective view of our improved tile molding machine. Fig. 2, is a front elevation showing the machine in an open position. Fig. 3, is a vertical section through the same partly in elevation, and, Fig. 4, is a perspective view of the cores and piston.

In the drawings A, indicates a pair of standards connected together at their lower end by a baseboard A, and provided with feet A for holding the standards in a rigid position.

The upper ends of the standards are bi- Speeification of Letters Patent.

furcated and to their inner sides are secured strips B, forming guide-ways, in which is slidably mounted a cross bar C, having outwardly extending ends forming handles C, and carrying a board 0, to which the upper end of the arms D, of circular tampers D, are connected, which work on members F, carried by spring arms F, secured to one edge of a hopper G, which is provided with oppositely disposed arms G, extending through the guide-ways of. the bifurcated ends of the standards, and locked in position by spring catches H. The members F serve to keep the tampers clean by dislodging any material which adheres to the inside thereof when they are raised. It will be seen by this arrangement the hopper can be moved up and down as will be hereinafter fully described, and connected to the strips forming the guides, are buttons G for locking the arms G, when forced upwardly.

. Secured to the board and cross bar are blocks C provided with beveled faces adapted to engage spring members I, carried by an arm I, which is pivotally mounted in an ear of a plate I connected to one side of the hopper so that as the tampers are moved up and down, the hopper will be vibrated,

whereby the contents of the same will pass out through the bottom.

Mounted between the standards A, on shafts J, are arms K, which are spaced from the standards by blocks J, which have secured between their upper ends a bed plate L, provided with a side L, and to the edge of which is hinged a side M, carrying a mold section 1W provided with a plurality of semicircular grooves M the section being supported by a cross bar M, in an inclined position as clearly shown at Fig. 3, when the mold is in an open position.

A removable mold section N, provided with a plurality of semicircular grooves N, is arranged against the side L, of the bed plate L, the grooves registering with the grooves of the section M, forming cylindrical molds. The section is provided with outwardly extending arms N carrying angle supporting members N for supporting a pallet board 0, which is provided with a plurality of openings in its bottom registering with similar openings formed in the bed plate L, in which are mounted cores P, carried by a head P, which is provided with a piston P having a rack portion P adapted to mesh with a gear Q, secured on a shaft Q mounted in the apertured ends of plates Q, secured to the lower ends of the arms K.

The piston P extends through a bracket- Q secured 011 a cross bar Q, connecting the arms, so that it will be held into engagement with the gear Q, at all times. Secured to the ends of the shaft Q are gears R, meshing with segmental racks It, secured to the standards A, for rotating the shaft Q as will be hereinafter fully described.

The arms K, are provided with upward extensions K forming handles, so that the arms can be swung outwardly as clearly shown in Fig. 3, and are securely locked in a vertical position by the arms G, of the hopper Gr, so as to hold the mold sections together.

For securely locking the mold sections together so as to form a tight joint, we provide the fixed section h with hooks S, adapted to fit over pins S, secured to the side L. A

lVhile we have shown and described a machine especially adapted for making tile, it is of course understood, that by changing the mold sections and tampers, bricks can be readily made.

The operation of the device is as follows: The removable mold section with a pallet board is placed upon the bed plate, the machine being in the position as shown in Fig. 3, which is then moved into the position shown in Fig. 1, material is placed in the hopper and by working the handles up and down, the tampers will force the material tightly down around the cores P, which are forced upwardly in the molds in this position, and as the tampers are working up and down, the hopper is vibrated so that the material will be fed into the molds. By drawing the hopper upwardly the arms K, can be swung outwardly, the gears R, riding over the racks R, causing the piston P to be drawn downwardly so as to Withdraw the cores P, from out of the tiles, and by grasping the arms N of the removable section of the mold with the pallet board which supports the molded tiles, it can be readily removed, and the tiles on the pallet board placed on a suitable support until they be come hard.

Having thus described our invention what we claim as new and desire to secure by Letters Patent is 1-- 1. In a machine of the kind described, the combination with standards of a pivotally mounted bed plate having a fixed side, a side hinged to said plate provided with a mold section, and a. mold section carried by the fixed side provided with means for supporting a pallet board.

2. In a machine of the kind described, the combination with standards, of arms pivotally mounted between the standards carrying a bed plate at their upper ends, a shaft carried by the lower ends of said standard provided with gears, separable mold sections ar 'anged on the bed plate, cores slidably mounted in the bed plate carried by a piston provided with a rack portion adapted to engage one of the gears of the shaft and racks secured to the standards for rotating'said gears when said arms are moved.

3. In a machine of the kind described, the combination with standards, of arms pivotally mounted between said standards carrying a bed plate and a shaft, gears secured on said shaft, cores slidably mounted in said bed plate carried by a head, a piston carried by said head provided with rack portions meshing with one of said gears, and racks secured to the standards for rotating said gears.

at. In a machine of the kind described, the combination with standards, of arms pivotally mounted between said standards carrying a bed plate provided with a fixed side, a side hinged to said bed plate, a mold section secured to said hinged side, a removable mold section arranged on the bed plate against the fixed side, means for locking said mold sections together, a hopper arranged above said mold sections and tampers working through said hopper, for the purpose described.

5. In a machine of the kind described, the combination with standards provided with guide-ways at their upper ends, of arms pivotally mounted between said standards carrying a bed plate provided with separable lllOlC sections, a shaft carried by said arms provided with gears, a piston provided with a 'ack portion meshing with one of said gears, a head secured to said piston provided with cores working through the bed plate, a hopper slidably mounted between said standards, a cross bar mounted in the guide-ways of the standard carrying circular tampers extending through said hopper, and rack portions secured to the standards for operating said gears, for the purpose described.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
