APPARATUS FOR THE MANUFACTURE OF ARTIFICIAL STONE. SPECIFICATION forming part of Letters Patent No. 311,69d, dated February 3, 1885. Application filed October 2, 18 4. (No model.) a, whom it may concern: Be it known that I, O. IRVINE WALKER, a citizen ofthe United States, residingin Charleston, South Carolina, have invented certain 5 Improvements in Apparatus for the Manufacture of Artificial Stone, of which the follow ing is a specification. My invention consists of an improved apparatus for preparing and mixing ingredients to for the economical manufacture of artificial stone and similar substances, as fully described and claimed hereinafter. In the accompanying drawings, Figure 1 (Sheet 1) is a view of the general construction and arrangemcntofthe whole apparatus. Fig. 2 (Sheet 2) is a longitudinal section of the mixer, and Fig. 3 (Sheet 3) is a transverse section of the same. I prefer to make the building, Fig. 1, in which the apparatus is arranged of sufficient height to enable the material to pass down through the successive machines to the mold ing-table by gravity. In the drawings I have shown the building as a three-story'building, the third floor of which is adapted to receive the materials to be treated. I may also have there a grinding-mill, B, as indicated by dotted lines, to be used for such material as requires to be ground; or it may be ground in a 0 separate building. On the second tloor is the mixing-machine D, while on the ground-floor is the moldingmachine F, preferably provided with a receiving-platform, E. The material is first carried by a suitable elevator, G, from the ground-floor up to the third floor, whence it is fed into the hopper d of the mixer D. The hopper (Z of the mixer is valved, and preferably constructed to measure the amount of the material fed into the mixer D. The 0 material ,when thoroughly mixed,is delivered down the chute c to the receiving-platform E. The grinding machine B and molding-ma chine F may be of any suitable construction, as they form no part of my present inven- 5 tion; but the construction of the mixer is illustrated in detail in Figs. 2 and 3. A barrel or cylinder, H, is mounted on a shaft or trunnions, I, having bearings in a suitable frame, K, the shaft I being provided with a gearwheel, 11,01 other means by which a rotary motion may be imparted to the cylinder. The cylinder is covered with a suitable nouconducting covering to prevent uneven condensation of steam, which is introdhced into the cylinder as hereinafter described. The shaft I at one end,or the trunnions, is hollow, and has an opening or openings into the interior ofth'e cylinder, while an extension of its outer end is adapted to turn in a hollow stuffing-box bearing, IL, with which communi- 6o cates the steam-supply pipe L, provided with a cock, Z, a pressureregulating valve, L, a safety-valve, M, and gage N. An injector, P, has a pipe, 10, extending down into a water reservoir or tank, 0, which is of a char 6 actor to indicate about the amount of water drawn up by the injector and forced through the pipe 19 into the mixing-cylinder H, so that the requisite proportions of steam and water may be supplied to the material in the barrel. The cylinder H is provided with a manhole, h, through which the material to be treated is introduced and discharged, and the cylinder is also provided with a blow-off cock, j, for blowing off steam. Instead of the injector, a pump or other means of securing ahead of water may be employed. I claim as my invention- 1. The within-described apparatus for the manufacture of artificial stone, said apparatus consisting of an elevator, a hopper, a mixingmachine communicating with said hopper, a chute into which the mixing-machine discharges, a platform onto which the chute discharges, and a moldingmachine adjacent to said platform, as set forth. 2. The within-described apparatus for the manufacture of artificial stone, said apparatus consisting of an elevator, a grinding-mill ad- 0 jacent to the top of the elevator, a mixing-machine below the grinding-mill, a receivingplatform below the mixing-machine, and a molding-machine adjacent to the platform, as set forth; 3. The herein-described mixer,consisting of a revolving cylinder with a nonconducting covering and steam and water supply pipes. 4. The combination of the revolving mixingcylinder with steam-supplypipe,waterreservoir and injector, or other device for supply ing an ascertained quantity of water to the 5 material in the cylinder. 4 5. The combination ofthe revolving mixingcylinder with a water and a steam supply pipe having a pressure -valve, safety valve, and gage, substantially as set forth. O. IRVINE XVALKER. Witnesses: I R. B.
