terial that is used, and to open to receive the E, is the out edge, or periphery of the cylinder. These cylinders may be cast solid, excepting the door and ends, and air-holes; and either of the various forms may be used in the same furnace.

F, is the water leg, extending from the crown sheet of the boiler, or fire-box, to near the lower edge of the coking cylinder, and supporting` the back end of the hollow shaft of the coking cylinder.

I, is the water pipes that protect the cylinder.

H, is the end door of the coking cylinder.

U, is the shaft, and pulley, and endless screw, and band, that moves the coking cylinder from the main shaft.

D, is the opening from the top of the furnace or boiler, to feed the coking cylinder, shown Fig. 2; W, the handle that raises the endless screw out of gear, to stop the cylinder at pleasure; X, the slide door as shown Fig. 7 Y, the door as shown Fig. 6; Z, the slide door as shown Fig. 8; Z9, the crank that turns the cylinder when not in motion.

After the fuel falls from the cylinder to the grate, I provide a vibrating Hearn-tooth rake, that works between each grate-bar at the same time, with the teeth turned up, to facilitate the combustion of the fuel, and after the smoke, and gas, passes from the furnace, they pass into a combustion chamber, where I provide an atmospheric pillar formed of lirerlay, or black lead, to facilitate the combustion of the gases. In this pillar, I insert an iron air-tube extending to near the top of the pillar, to meet the light combustible gases. The smoke, and gases then pass through what I call a gas heater.

y The air that supplies these pillars, may be taken in hot from the back of the furnace L, or be taken in cold from the bottom of the combustion chamber, as shown letter M. After the smoke, and soot, or sparks, pass to the top of the smoke stack,-I provide a director to prevent the soot, and sparks from coming in contact with the trains in the rear; and when passing through a city or village, a valve closes the director, and opens the top, and lets the sparks out, in the ordinary way.

I, is the Hearn-tooth rake; G, the arm that works the ieam-tooth rake.

K, is the rod that raises and lowers the rake.

L, is the valve that lets in the hot air; M, the cock that lets in the cold air; N, the gas pillar; O, the air-pipe inserted in the pillar; P, the gas heater shown at Fig. 4; Q, the bevel wheel that revolves with the director, moving in a groove on the top of the smoke pipe.

R, is the spark and soot director; S, the valve that closes and opens the director.

T, is the chain that lowers and raises the valve.

a is the shive, on the bottom of the director, moving in a groove, on the top of the smoke pipe.

C is the crank, and shaft, that the attendant revolves the director at pleasure.

I do not claim a coking oven, as now used; but

I claim- A coking, or drying-cylinder, or box, hung on a hollow shaft, in the fire-box of a boiler, or other furnace, over, or above, the grate, the shaft being perforated with holes, to allow the atmosphere to pass in, by a cock or valve, to commingle with the coal and gases as the cylinder revolves; and if necessary `to pass from the hollow shaft, through the arms, to the rim of the cylinder, and then pass out in jets, these cylinders to be revolved at pleasure, substantially as set forth for the purposes herein described, and made to operate.

MELLEN BATTEL.

In the presence of- JoHN CosTIGAN, JOHN BURTON.
