TILE-MACHINE.

SPECIFICATION forming part of Letters Patent NO. 519,773, dated May 15, 1 894:.

Application filed April 22,1893- Sezial No. 471,487. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM H. PRIDE, a citizen of the United States,residing at S pring field, in the county of Sangamon and State of Illinois, have invented a certain new and useful Improvement in Tile-Machines, of which the following is such a full, clear, and exact description as will enable those skilled in the art to which it pertains to make and use my said invention.

My improvementis intended to be attached to any of the force-feed tile machines now in common use.

I do not lay any claim to the tile machine itself, and hence illustrate only so much of the machine as is necessary to illustrate the connection of my improvement therewith.

The purpose of my invention is to provide means whereby any suitable configuration or ornamentation may be given to the tiles as they emerge from the machine.

Reference is hereby made to the accompanying drawings in which- Figure 1- is a perspective view of my improvement connected with the tile machine. Fig. 2-- is an enlarged detached view of one of the housings in which the impression roll works. Fig. 3- is a detached view of an alternative construction of the molds adapted to be used in the bed. Fig. 4- isa detached View showing an alternative form of the impression roll, also showing an alternative form of mold adapted to be used in the bed. Fig. 5-- is a representation of some of the various designs which may be impressed on the tiles by means of my improvement.

Similar letters indicate similar parts in all the views.

The pug mill A is of ordinary construction and may be provided with any suitable means for kneading the clay and forcing it through the mouth a of the mill. The bed B may be connected in any suitable manner with the pug mill, and this bed is supported on suitable legs I). The bottom of the bed may be flat, or may be provided with channels 0, or may be rounded, ridged or furrowed in any suitable manner to give any desired form to the under side of the tile. The bottom molding surface may be integral with the bed. I prefer however to use molds O detachably connected with the bed in any suitable man- It is obvious that great variety in the form of the bottom of the tiles maybe obtained by varying the forms of the channels in the bed.

The impression roll D is journaledin boxes d, and theseboxes slide in housings E, which are bolted or otherwise suitably secured to the bed B, being guided by lugs (1 moving in vertical slots e in the sides of the housings. Within the housings and on top of the sliding boxes are coiled springs F, and above the springs are followers G, which also move vertically and are guided by lugs on the followers, said lugs moving in the slots 6. In the top of the housings are screws H which may be turned down on top of the followers, thereby compressing the springs F and giving elasticity and any desired pressure to the impression roll.

In the drawings I have shown only one impression roll, but in practice two or more rolls may be used, placed parallel to each other, or placed end to end, without departing from my invention.

On the periphery of the roll D are wrought the forms and designs 01 which it is desired to give or to impress upon the face of the tiles. These designs may be either in relief or in intaglio, and a great variety of designs may be used. In Fig. 5 I have indicated a few of them, but I do not confine myself to the designs shown. A single design may occupy the entire surface of the roll or two or more designs may be placed side by side or end to end on a single roll. It is obvious also that the roll may be ridged and furro wed as shown in Fig. 4, or may have any other suitable form, thus adapting the machine to produce great variety in the form as well as the ornamentation of the upper surface of the tiles.

The impression roll D is made solid and heavy so that the. weight of the roll may be the bearings of the roll to rise in the housings when there is undue pressure on the roll thus permitting the roll to pass over hard substances in the clay without injury to the roll.

The operation of my machine is as follows:

The clay after being properly ground and kneaded in the pug mill A is forced out through the mouth a, in a yielding and pliable mass .into the mold O in the bed B, and is pushed along in the mold and under the rollD. The pressure of the movingclay actuates the roll and the pressure of the roll forces the under side of the clay into the .channels 0 in the molds, and at the same time the roll impresses on the upper surface'of the clay the form or the design which is wrought in the periphery-of the roll, and this operation continues as long as the clay continues'to issue from the mouth of the pug mill.

The slab-of clay formed andimpressed, as

above describedmay bereceived onany suitfor propelling said slab of clay in such mannor as to rotate said roller by the pressure of said moving slab of clay acting against the periphery of said roll, as set forth and for the purpose stated.

2. In a tile machine, the combination of the bed adapted to be connected with the mouth of the pug mill, the longitudinal mold detachably connected with the bed, the housings on the bed and the roll journaled and vertically movable in said housings, as set forth and for the purpose stated.-

3. In a tile machine, the combination of the 7 bed attachable to the mouth of the pug mill, the longitudinal. molds detachably secured in said bed, the housings on the bed, the boxesslidin g in said'housings, the impression roll journaled ,insaid boxes, the springs acting against said boxes, the followers in the housingsabove the springs and the screws operating said followers-asset forth and for the purpose stated.

4. In a tile machine, the @bed attachable to the pug mill and adapted .to impress on one side of the tile the counterpart of the conformation of thesurfaceof the bed, incombination with the vertically adjustable and WILLIAM H. PRIDE.
