IMPROVEMENT IN APPARATUS FOR BURNING GAS-TAR.

Specification forming part of Letters Patent No. 142,357, dated September 2, 1873; application tiled April 23, 1873.

To all 'whom it may concern:

Be it known that I, ANANIAs SMITH, of Niagara Falls, in the county of Niagara and State of New York, have invented a new and Improved Mode and Apparatus for Burning Gas-Tar, of which the following is a specification:

My invention consists in constructing the apparatusV with a reservoir for containing the gas-tar, having steam-jackets and steam-pipes for heating it to the proper degree to increase its liquidity, and admitting steam to the surface of the gas-tar to force it through the pipes to the combustion-chamber.

The apparatus is fully illustrated by the drawings, of which Figure I'is a horizontal section through the iire-boX, decomposing-retort, and the burners. Fig. II is a vertical section through the reservoir.

A is a section of a nre-box. B is the decomposing-retort, of which B1 is the pipe admitting steam thereto, and B2 the pipe through which it is conducted to the burners. C is the reservoir for the gas-tar, of which D D are steam-rin gs, connected by tubes D D. Steam is admitted to the rings and tubes through a pipe, d. Steam is also admitted to the main space of the reservoir containing the tar through a pipe, E. c is the pipe through which the tar -is forced to the burners. This pipe is shown disconnected in the drawing. In the apparatus it is connected to the pipe c, Fig. 2. A safety-valve, F, is arranged at the top of the reservoir G to permit the escape ot' steam should an increased pressure be created by the vaporization of a portion of the gas-tar. The pipe c may be incased Within a larger pipe, e, through which steam is allowed to' circulate, to assist in heating the gas-tar before it passes to the burners. G G are'the burners, consisting of the small tubes c for conveying the gastar, they being passed through the crosses ff in the pipe B2. Short pipes g g, having notches or slots i'rmed in their ends around the central bore, are passed over the ends of the pipes c and screwed into the crosses f. H H and H Vare cocks for shutting off and regulating the supply of gas to the burners. I is a similar cock for shutting oft' and regulating the steam.

Air is admitted through the door; or suitable openings may be left around the burners to admit regulated quantities of air to the fire; or air may be forced into the steam-pipe in a heated state, as shown at J, Fig. 1. Suitable valves j are arranged t0 regulate the quantity of air to be admitted.

Assuming that from the above description and the drawings the construction of the apparatus, With its various modifications, is fully understood, I shall now proceed to describe the mode of its operation.

The reservoir() being supplied with a suiiicient quantity of gas-tar, and the tar having been sufficiently heated by the steam in the tubes D to cause it to flow readily, steam from the boiler is admitted thereto through the pipe E, which forces the tar through the pipe c to the burners. Simultaneously with the admission of steam to the reservoir steam is also admitted to the decomposing-retort B through the pipe B1. After passing through the retort it passes through the pipe B2 to the burners, issuing through the slots, and commingling with the gas-tar as it issues from the i smaller tubes.

A light fire of, coal or wood may be kept in the furnace; or the tar and decomposed steam may be ignited by other means.

I claim- The combination of the reservoir C, having steam-rings D D and steam-tubes D D', the tar-conducting pipe c, and the burner or burners G, substantially as shown and described.

ANANIAS SMITH.
