APPARATUS FOR 'MANUFACTU RING GAS.

SPECIFICATION forming part of Letters Patent No. 294,534, dated March 4, 1884. I I Application filed OctobcrQB, 1883. (No model.) 1

To all whom it may concern:

Be it known that I, BURHANS VAN STEEN- BERGH, of Goshen, in the county of Orange and State of New York, have invented certain new and useful Improvements in Apparatus for Manufacturing Gas; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which itappertains to make and use the same, refer ence being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to an improved apparatus for manufacturing heating or illuminating gas; and the object of the invention is to provide a readily portable apparatus, which shall be simple in construction and convenient of operation, and which may be transported in sections and quickly set up, for making gas on a comparatively small scale. The apparatus, by its construction, however, is adapted togenerate gas quite rapidly and in large vol-. Gas is made ume as compared with itssize. by the decomposition of steam and a hydrocarbon oil in contact with anthracite coal or coke or-other suitable material in heated re,- torts and fixing the gas in a separate heated retort. v

The construction of the apparatus is illustrated in the accompanying drawings, in which Figure 1 represents a vertical longitudinal sec tion of the apparatus. Fig. 2 represents a h orizontal section just above the lower tier of retorts. Fig. 3 represents a vertical cross-section.

The retort-furnace A has its walls built up of ordinary brick, lined internally with fireclay tiles or slabs, and covered externally with a jacket of plate-iron, cast or rolled. The sides of the furnace are preferably made in sections, which are bolted together when the furnace is set up, and they are of such dimensions that they may be conveniently packed and transported, and so that any oneimay be readily detached from the wall, in order to admit workmen to repair the inside of the furnace or to remove and replace any defective or worn part or section of the generating-retorts.

The usual grate, 13, supported at its ends uponledges or lugs, is provided, separating .the ash-pit from the fuel and retort chamber 0, and in the front wall are doors I) I), opening, respectively, into the fuel-chamber and the ash pit. A partition of fire-clay tiles, D, separates chamber 0 from the upper chamber, F, and such partition is provided at the rear end of the furnace with two openings, (1 d, which may be partially or entirely closed by dampers ac, the rodsor handles of which should pass out through the wall of the furnace. In the rear wall is builta deflectingbridge, E, projecting into chamber 0, above the retort-s, for causing reverberation of the flame and heated products over the tops ofthe retorts, and thereby better-heating them. The top or crown of the furnace is constructed of inclined fire-clay slabs or tiles A A and the horizontal central tile, A. The inclined tile A throws the hot products of combustion against the sides of the retort, and thus uni-.

formly heat it and economize the heat in the most advantageous manner. A chimney, I, for the escape of products of combustion, and having a regulating-damper, i, rises from the top of thefurnace, near the front end thereof, so that the hot products are compelled to pass the whole length of chamber F and impart their heat to the fixing-retort.

I The decomposing retorts or conduits H are composed of numerous straight sections, extending transversely across the chamber 0 through walls, and are connected together out side of the walls by' return-bends h. The straight sections and bends are provided with flanges, which are tightly secured together by bolts or screws, so that the return-bends may be readily removed for charging the retorts with coal or other material and cleaning them out when necessary. At the farther end of the series of retorts, near the rear of the furnace, a pipe, K, connects them with a fixingretort, L, in chamber F. vided with the usual mouth-piece, L, having a This retort is proi tight-fitting lid, and a pipe, t, is-provided for I conducting gas to the hydraulic seal or washbox, or to any place of storage or use. A steam-supply pipe, 11., connects with the: re-- turn -bend uniting the second and third retort, and an oil-supply pipe connects with the first retort. In making illuminating-gas, naphtha IOO a fire is kindled on the grate and maintained as long as the production of gas is continued, and the retorts and contained coal or coke are first raised to or about an incandescent, heat. Then steam, preferably in a superheated state,

' is admitted into the retorts and decomposed retorts H.

by contact with incandescent or highly-heated carbon, forming hydrogen and carbonic oxide. Hydrocarbon oil is also admitted and converted by the heat into rich earbureted-hydrogen gas, which serves to carburet or enrich the hydrogen and carbonic oxide resulting from the decomposed steam, and thus form an illuminating-gas. The gases from the decomposed steam and that from the oil are conducted into the fixing-rctort L, where they are com bined and converted into a fixed illuminatinggas of high candle-power. Should it be found that the heat is too high for safely and economically admitting hydrocarbon oil into the retorts H, it may be admitted into ascending pipe K, and there be vaporized by thehot gas, passing to retort L; or the oil may be admitted into retort L near the inlet for the gas from The gas, on leaving the fixing-retort, may be washed with water and purified by lime in the usual manner, though for many 40 purposes little or no purification will be re quired. Broken brick or pumice-stone may be charged into the retorts,vfor affording a large heating-surface, instead of coal or coke, and gas be made from steam and oil only.

Having described my invention, what I claim, and desire to secure by Letters Patent,

1.'The retort-furnace having a deflectingbridge projecting from its rear wall, in combination with the connected series of retorts arranged as and for the purpose described.

2. The retort-furnace having the deflectingbridge projecting from an end wall, and also having a horizontal partition provided with openings at one end, dividing the furnace into two chambers, in combination with the retorts, arranged as described.

3. The horizontal series of retorls extending transversely across the furnace,and connected outside the walls by return-bends, and having supplypipes for steam and oil connected with one or more of the retorts, in combination with the fixing-retort, a connecting-pipe, and the horizontal partition, having passages and separating the first series of retorts from the fixing-retort, for the purpose described.

4. The furnace A, constructed with deflect ing-bridge E, partition D, having openings d at one end, the chimney I at the opposite end of the furnace, and with slanting crown-plates A, in combination with the connected generating-retorts H and the fixing-retort L, as and for the purpose described.

In testimony that I claim the foregoing as my own I aiiix my signature in presence of two witnesses.
