GAS APPARATUS.

Specification of Letters Patent.

Application filed July 12, 1909. Serial No. 507,239.

To all whom it may concern:

Be it known that I, JOHN F. KIsTLnR, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Gas Apparatus, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to an improved gas generator, incinerator and crematory, and is specially designed to be used in the manufacture of gas for illuminating, fuel, heat and power purposes, and is adapted and designed to extract the maximum amount of gas from coal, crude or refined oil, wood, vegetable matter, garbage or refuse from houses, stables, abattoirs, streets, and farms, corn stalks, cobs, hay, straw, and in fact any carbonaceous material that can be burned or decomposed by heat.

It is also specially designed for cremating dead animals and other refuse.

A further object is to so construct the apparatus, that no smoke is permitted to escape into the air, therefore producing a sanitary apparatus, which can be operated in or near a city with perfect safety, as to health.

I have also particularly designed my apparatus, so that it can be used in connection with any established gas-works, thus making it advantageous for any city or gas company to install, for the refuse from the city can be used to great advantage and thus turn a waste into a useful by-product.

With my apparatus, it is possible to manufacture a gas for approximately 10 per 1,000 cubic feet, and the by-products, I have found will practically pay the operating expenses.

To more clearly illustrate the invention, and bring out the many points of advantage of the same, attention is invited to the accompanying drawings, in which Figure 1 is a front elevation of my invention, showing the arrangement of draft and furnace door, and front view of the four retorts. Fig. 2 is a horizontal sectional view of the retorts, the furnace being in elevation. Fig. 3 is a rear elevation.

Referring to the drawings :the numeral 1 designates the fire-box, which is inclosed at its two ends with cast iron front and back 1, both of which are lined with asbestos. The sides and arch may also be of cast iron asbestos lined, or they may be of fire clay or brick. The fire-box is provided with a fire door 2, draft door 3, ash pit 4, and grate bars 5, the said grate bars being provided with suitable rests. The brick pier 6 supports the rear end of the grate bars, and forms a combustion chamber 7, having clean-out 8, and mounted in the front and rear walls and within the coinbustion chamber are the retorts 9, and superheaters 10. The retorts are provided with the doors 11, in front, while the superheaters are provided with the rear covers or caps 12. The front doors 11, are hinged as at 15, and in order to hold them tightly closed, I provide the lugs 15 which are adapted to receive the rod 14-, whose cam lever 16 bears against the face of the door 12, and when turned, forces the door inward and the rod 141 outwardly, thus firmly looking and holding the door closed. This rod 11 is bodily removable from the lugs 15, when it is desired to open the doors 11.

It will be seen that the retorts are separated from the super-heaters by means of the partition a, having opening 6, for passage of gases, and that the combined retorts and super-heaters are so mounted within the front and rear walls of the combustion chamber as to permit of easy repair, and quick removal and substitution. These retorts are made of a wrought iron lining and cast iron or clay for an outside casing, thus producing a more durable retort. It will thus be seen that the substance from which the gas is to be made is placed within the forward end of the retorts, which may be in any number to suit the size of the apparatus, and when heated, the gas passes from the main retort 9, into the auxiliary retort or super-heater 10, where the gasis superheated and allowed to pass through the exit 12, of the covers or caps 12, into the pipe 13, which is connected to the four way coupling or tee 14:, in whose opposite outlet is the blow-out pipe 15. Mounted in the lower outlet of the coupling is the pipe 16, which enters and terminates above the bot tom of the cylindrical tank or condenser 17, which is adapted to contain water approximately at the height of the dotted line. Connected to the upper member of the coupling is the pipe 18, whose upper end is connected to the clean-out pipe 19, and the goose-neck pipe 20, which enters and empties into the 1 gas main 21. Surrounding the coupling, and the various plpes leadlng therefrom is a v Patented J an. 11, 1910.

water acket 22, which cools the gas before it enters the main 21.

Supported in the front and rear walls of the combustion chamber is the small cylindrical retort 9 in which I decompose or volatilize the tar, this retort being similar in construction to the larger retorts 9. Leading from the top of the combustion chamher are the smoke outlets 24:, whose pipes 25 enter the fan-chamber 26, of what I term my smoke consumer, which is shown here combined with my gas apparatus, but I would have it understood, that it may be used in connection with power plants, furnaces of all descriptions, and in fact in any place where the creation of smoke is a nuisance, that must be abated. In the fanchamber, I mount a belt driven fan, and from this chamber I lead a pipe or flue 28, which empties or leads into the upper end of the smoke condensing tank 29, which has a series of vertical fines mounted therein. The lower end of this tank 29, is connected by a pipe 31, to the upper end of a settling or cleaning tank 32, which is filled with water, and is provided with the outlet vent 33.

From the foregoing description, the operation of my apparatus, is clearly understood, but briefly stated, it is as follows :The tire is made in the furnace, and when the retorts 9, are sutliciently heated, the doors 11 are opened and the wood, or other material to be used is then placed in the retort 9, the door being closed after a sufficient quantity has been placed in the retort. The substance being heated, gives ofi gas, which passes into the super-heaters 10, and from them into the pipe or condenser 18, the gas being separated from the tar or semi-solid matter, and passing upwardly into the main 21, and thence to the proper holder. The condensed tar and water together with all others impurities collect in the receiver 17, where the tar is separated, or if desired automatically enters the rear of the small retort 9 through the pipe 17, where it is reduced further to a gas, and passes from this retort through its rear cover 12, into a condenser 18. The remaining liquid in the tank 17, may be separated by distillation or other chemical action. W'hen the gas is all extracted, the doors 11 are opened, and the charcoal, coke or ash is removed.

It is evident from the foregoing that I provide a very simple, durable and inexpensive gas generator, which can also be employed asan incinerator or crematory, thereby producing a thoroughly efiicient and practical apparatus.
