UNITED STATEs PATENT OFFICE IMPROVEMENT lN TILE-MACHINES.

Specification forming part of Letters Patent No. 158,570, dated January 12, 1875; application filed October 20, 1874.

To all whom it 'may concern:

Beit known that we, THOMAS E. CHANDLER and FRANKLIN TAYLOR, of Indianapolis, county of Marion and State of Indiana, have invented an Improvement in Tile-Machines, of which the following is a specification:

The object of our invention is to improve the devices used in tempering clay and molding it into tiles; and it consists in the construction and arrangement of the dilerent parts of the machine, as hereinafter described.

Figure 1 represents a vertical section of our improved tile-machine. Fig. 2 represents a plan and partial section of the same. Figs. 3 and 4 represent a side and bottom view of the inclined feed-wing. Figs. 5 and 6 represent a front and sectional view of the plungerhead and packing-plate. A

A represents a cylindrical case, secured on thetop of the piston or pressure box E,and has a shaft, B, passing through the center of the case, and through abox, V, into the pressure-box E. The box V is constructed oi' two pieces, and has a conical-shaped exterior, which ts into a conical hole in the top of the pressure-box E, and is held in its proper position by bolts passing through the ilange on the lower side of the box,andthrough the top ofthe pressure-box. This box V is'so constructed that as the box or journal on the shaft B becomes worn, it can be taken out and a new one substituted 5 otherwise the hole in [he top of the pressure-box E would have to be bushed or have a new top. On the lower end of the shaft B is a crank-plate, F, which has a roller, Gr, on the crank-pin Y. This roller works in the recess Hof the double-headed piston Z. 0n each end of the piston Z lthe adjustable heads J and'J are bolted. These heads are provided with an adjustable plate, K', which is bolted onto the lower front faces of the heads J and J, the bolts K passing through' slotted holes in the adjustable plates K' K Immediately above the plates K' K', and cast on the heads J J, are two or more lugs, through which the adjustable screws O O are inserted, for the purpose of holding the adjustable plates K' K' in their proper position before the bolts X are made fast. The screws O O, when screwed down, lift the heads J and J, and close up any openings that may have been worn at the top or bottom of the pressure-box E. On the side of the pressure-box E (represented at \V W) are recesses formedin the sides for the reception of the packing-plates K. These plates are held in the recess by the bolts P P, and each plate K can be adjusted by loosening the nuts on the bolts P P and adjusting the setscrews R R. This arrangement keeps the ends of the pistons J J packed on`each side.

The operation of our improved machine is as follows: As'the shaft B is revolved, the arms C mix the clay, and the feed win g l), by its inclined position and curved end T, forces the clay into the chambers of the pressure-box E at each end of the piston-heads J and J, through the openings S S alternately, and as the pistons move forward at each end, the clay is compressed and forced out through the dies at each end.

We do not claim, broadly, the feed-wing D, asthat is old.

What we claim as new, and desire to secure by Letters Patent, is v' The pressure-box E, provided with packingplates K K, the pistonZ, having the recess H, and provided with piston-heads J J, with adjustable packing-plates K' K', in combination with the operating mechanism,consisting of the shaft B, crank F, and roller G, as and for the purpose specilied.

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

THOMAS E. CHANDLER. FRANKLIN TAYLOR.
