APPARATUS FOR THE MANUFACTURE OF GAS.

SPECIFICATION forming part of Letters Patent No. 480,211, dated August 2, 1892.

Application filed April 4, 1892. Serial No. 427,708. (No model.)

To all whom it may concern.-

Be it known that I, LEWIS G. PARKER, a citizen of the United States of America, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Apparatus for the Manufacture of Gas, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention has for its objects to make an illuminating and heating gas from crude petroleum, or liquid hydrocarbons, air, and steam.

I-Ieretofore the oil has been injected into the highly-heated fixing-furnace in the form of a spray, the lighter and heavy parts together, thereby entailing aheavy loss in not only not converting the tar or asphaltum portions into gas, but resulting in its loss, forming lampblack and impairing the efficiency of the converter and lowering the quality of the gas produced. By my method of operation all of the hydrocarbons susceptible of forming into a perfect gaseous state is carbureted out by passing air through the petroleum while in a boiling condition, leaving the tar or asphaltu m to be drawn off and saved without loss. It will also be observed that my generator or apparatus is alternative in operationi. 6., the converter checker brick-work or fixing medium is rendered hot enough to decompose and fix the passing gases, permitting the using of the gases in that state, the making of the gas then being stopped and the checker brick-work reheated.

To these ends the invention consists in the combination and arrangement of parts, including their construction, substantially as hereinafter more fully disclosed, and pointed out in the claims.

In the accompanying drawings, Figurel is an end sectional elevation of my invention, showingthe interior of the converter and front of generator-furnace, so as to disclose the position of the vaporizer and carburetor and boiler and the passage for the heat between said vaporizer and carburetor and boiler. Fig. 2 is a side elevation thereof, showing the vaporizer and carburetor and air-pump. Fig. 3 is a plan View of the same; and Fig. etisabroken, partly sectional and side view of the invention, showing the passage of heat from the fire under the boiler and the heat from the converter and pipe E, delivering it under the vaporizer and carburetor.

In my invention one of the objects is to utilize waste heat from the steam-boiler and from the vaporizer and carburetor, to maintain the petroleum in the latter at proper temperatures, so as to carburet air in its passage up through the crude oil freely.

In the embodiment of my invention I employ a converter G, consisting of a shell or cylinder lined with fire-brick and having a combustion-chamber g at the base and an opening g at the top, covered by a hinged or lifting cover g The space above the combustion-chamber is filled with the usual checker fire-brick work G. The combustion-chamber g has a door g held in place by a handwheel screw g working in a support 9 held outward from the converter G by rods 9 passing through said support and suitably secured or screwed to the front of the converter; also leading from the shell G is a pipe 9 for the outlet of the gas, and with the combustionchamber g connects apipe (1,, leading from the vaporizer and carburetor A, for supplying said combustion chamber with mechanical gas; also communicating with said combustionchamber is a pipe 0, having an ordinary atomizer or oil burner ll for highly heating the converter.

D is an ordinary air-pump driven by steam from the boiler B, said steam passing through pipe I) to said pump; also, from pipe 1) extends a branch pipe 1), leading steam to the burner-pipe c, which latter is also connected by a branch pipe 5 with the air-pipe d for the admission of air to pipe 0, when desired. Pipe 0 admits oil to the pipe 0 for generating heat at the burner H in the combustion-chamher 9 of the converter G. From the pump D air is forced into the vaporizer and carburetor A through the pipe d.

In the vaporizer and carburetor, for rapidly carbureting air with petroleum or a heavy hydrocarbon crude oil, I arrange, similarly to the tubes of a steam-boiler, sheet-metal plates 1 2 3, riveted at their longitudinal edges, and at alternately-opposite ends to the sides and ends of the shell, the free or other ends of said plates being spaced off from the respective end of said sheet. Sheet or plate 1 is located a few inches from the bottom of vaporizer and carburetor, with its riveted or secured end directly above the point of connection of pipe (1 with said vaporizer and carbu retor.

3y reason of the above arrangement of the sheets or plates 1 2 3 the air is caused to pass through the petroleum from end to end of the vaporizer and carburetor, as shown by the arrows. The end L of vaporizer and carburetor is preferably removable. It will be noticed that in this vaporizer andcarburetor the air to be carbureted is forced in at the bottom through pipe (Z and under a pressure while the crude petroleum is in a boiling state, as crude oil cannot be made to carburet air if not very hot.

The vaporizer and carburetor A has an outlet-pipe a for gas and an inlet-pipe a for oil, in addition to the inlet-pipe (Z for air and an outlet-pipe (Z to draw or let off the tar or as phalt.

It will be observed that the hood g secured to top of converter, prevents the products of combustion from escaping during the time the lid 9* is raised while blowing up or getting up the heat in the converter, the lid or cover g being raised by the wire rope g and lowered, as desired.

The boiler B is of the ordinary tubular type, set within the brick-work with fire-box for burning petroleum or coal, as desired, and the generator A is located above the boiler, leaving a space between them,so as to permit the products of combustion, after passing forward through the tubes of the boiler, to pass along the bottom sides of the generator and out the flue I.

The apparatus is operated for producing illuminating or heating gas as follows: Having tilled the vaporizer and carburetor A with crude petroleum up to the top of the upper sheet or plate 3 and raised steam in the boiler B, the valves 0 are opened, so as to allow steam, oil, and air to pass in proper proportions into the combustion-chamber of the converter and the lid or cover raised, and the vaporized hydrocarbons in said chamber are now ignited, the action of which soon heats the brickwork in the generator to a high degree. The products of combustion afterleaving the converter pass out through the pipe E and under the vaporizer and carburetor A, and thus assist to heat the petroleum in said generator. As soon as the converterbrickwork, commonly known as checker-work, is properly heated, the burner H is shut 01f, and the lid 9 is closed and the air-pump started when air is forced into the vaporizer and carburetor through the pipe (Z. The air passing up converter, enters the latter at a. At the same time a small amount of steam being allowed to enter the combustion-chamber g at the burner II, the mechanical gas from the vaporizer and carburetor Aand the steam are subjected to a heat sufficient to produce decomposition and form a chemical combination or fixed gas, which is allowed to pass out of the pipe 9 to the washer and holder.

As disclosed in Fig. 1, the relight-ing of the gas at the burner in the converter maybe effected by a supplemental jet from the valved pipe-opening close thereto.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s
