HYDROCARBON-VAPOR APPARATUS.

Specification forming part ofV Letters Patent No. 27,470, dated March 13 1860' Reissued March 10 To all whom it may concern:

Be it known that I, F. S. PEAsE, of Buffalo, in the county of Erie and State of New York, have invented a new and Improved Apparatus for Impregnating Gas, &c., with the Vapors of Hydrocarbon Liquids; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, forming a part of this specification, in which- Figure l represents a longitudinal vertical section of this invention. Fig. 2 is a horizontal section of ditto, the line fr Fig. l, indicating the plane of section.

Similar letters of reference in both views indicate corersponding parts.

To enable those skilled in the art to make and use my invention I will proceed to describe its construction and operation.

A represents a vessel or box of sheet metal, wood or any other suitable material, and of considerable height so as to give room for a number of shallow pans, D, which are sccured in the interior of the box at certain distances one above the other. These pans are fitted into the box in such a manner that between the ends of the pans and the side walls of the box, spaces, o, are left alternately on one and on the other side of said box and pans, as clearly shown in the drawing. These spaces are covered over by strips, o, of wire gauze or of perforated sheet metal which extend from the ends of the pans in a slightly inclined position up to the side walls of the box.

The upper part of the box, A, communicates by means of a pipe C, with the gasometer, and a pipe, D, extends from the bottom of said box into the condenser, E, which consists of two concentric tubes, c CZ, one inside the other, as clearly shown in Fig. l. The inner tube, o, is of cylindrical form from one end to the other, and the upper part of the tube, d, forms also a cylinder, which surrounds the inner tube, leaving a passage, c, for the gas. The bottom part of the tube, (l, is conical, so that the passage, c, increases in width as it approaches the communicating pipe, D, and a disk, f, of wire gauze, or of perforated sheet metal is slipped over the tube, c, in such a manner that the passage, e, is completely stopped up a short distance above the communicating tube, D, and that all the gas has to pass through the perforations in said disk.

The conical part of the tube, c, is cut open so as to give access to the interior of said tube for the purpose of cleaning the same.

The upper end of the condenser, E, is furnished with pipe, F, which conducts the gas to the burners.

The pipes, C and F, are connected by a pipe, G, which is closed by a stop-cock, g, and another stop-cock, 7L, is secured to the pipe, C, close over its point of connection with the box, A. Then the latter cock is closed, and the cock, g, is opened the gas as it comes from the gasometer passes directly to the burners without making its circuit through the apparatus. But if the cock, g, is closed and the cock, t, is opened, the gas has to pass through the box, A, and through the condenser, E, before it reached the burners.

The hydro-carbon liquid is introduced through an opening, 2'., on the top of the box, A, and a suflicient quantity of liquid is poured in to make the several pans overflow. The surplus liquid is removed from the bottom of the box by a faucet, y'.

Then the gas enters the top of the box, it strikes directly on the surface of the liquid in the upper pan, and it is forced through the strip of wire gauze, or of perforated sheet metal at the end of this pan, whereby it is slightly arrested and caused to be evenly spread out over the sheet (b) passing through the same and striking upon the surface of the liquid in the panabelow in the form of an even stratum or current of the saine width as the perforated plate (c) and so on through each plate and over each pan until the gas arrives at the bottom of the box from which it passes through the condenser to the burners. The perforated plates thus serve to check and spread the gas as it advances, preventing one portion from moving faster than the others and causing the gas to be delivered in a steady manner.

The use of perforated tubes and devices to steady and spread the How of gas is well known and is not claimed broadly, as my invention.

The combination of the gas supply pipe C, with the top of the apparatus so that the gas shall enter at the upper part and be forced downward as shown, causes the gas to pass along over the entire surface of the pans. The pressure or suction being downward, the gas flows close along the surface of the pans, whereas if the flow were upward in this apparatus, it is obvious that the gas would pass close up against the bottoms of the pans, while at the end of each pan, immediately below the perforated plates, there would be a chamber into which the gas would ascend, and almost wholly escape contact with the liquid in that portion of the pan beneath said chamber. But by causing the gas to owdownward as set forth, the vapor pours from the surface of one pan directly down upon the next below and so on through the series.

By passing the gas, as it emanates from the box, A, through the condenser, E, before it reaches the discharge pipe, any sudden decrease in the temperature causes the less Volatile parts of the gas to condense and to form a deposit on the bottom of the conl denser from whence it can easily be removed, whereas, if the gas passes from the box, A, directly to the discharge pipe, a sudden decrease of the temperature causes a deposit in said pipe, whereby the free passage of the gas is obstructed, and from whence said deposit can not be removed without considerable trouble.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

The combination of the box A, when provided with a supply pipe C, at the top, and with pans B, and plates as shown, with the condenser E, constructed as set forth, the whole operating in the manner and for the purpose herein represented and described.
