WILLIAM WYRIGHT, OF NEW YORK, N. Y.

SPECIFICATION: forming part of Letters Patent so. 712,169, dated October 28, 1902, Application filed June-*1, 1901. Renewed March 4, 1902. Serial No. 96,613. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM WRIGHT, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Carbureters,of which the following is a full and complete specification, such as will enable those skilled in the art to which it appertains to make and use the same.

The object of my invention is to provide a carbureterofa newand improved form wherein the size of the carbureting-surface will be exceedingly large in proportion to the cubic capacity of the device and in which the carbureting fluid will be equallydistributed to all parts of the chamber.

To such ends my invention consists, in substance, of an imperforate outer casing, a plurality of upright carbureting-tubes located within the casing and provided with perforations in the side Walls adjacent to the bottom and in the bottom, a free air-space beneath the carbureting-tubes, free air-spaces between the tubes, a fluid-chamber for holding the carbureting fluid located in the top of the casing and in communication with the interior of each of the carbureting-tubes by a downwardly-extending pipe provided with numerous perforations at the end and sides,

an inlet-pipe for the air in communication.

with an exterior inlet-chamber, an outletchamber, an outlet-pipe for the escape of the carbureted air in communication with-the outlet-chamber, and a filling of absorbent spongy material located in the carburetingtubes.

In the accompanying drawings, forming part of this specification, in which like figures of reference designate corresponding parts in the several views, Figure 1 is a View of my improved carburetor in central vertical section, and Fig. 2 is a top view thereof in central horizontal section.

In the drawings the reference-numeral 1 designates the outer casing, which is usually of the rectangular form shown and is formed of thin sheet metal. Within this casing upon one side is an inlet-chamber 2in communication with an air-inlet pipe 3, and on the other side of the casing'is an outlet-chamher 4, similar to the chamber 3, in communication with an outlet-pipe 5, through which the air when carbureted passes to the receptacle prepared for it or the burner in which it is to be used. The central portion of the chamber is filled with a plurality of carbureting-tubes 6, usually of the square form in cross-section shown, secured to one another a short distance apart at the top and bottom by connecting-pieces 7,,and the mass of tubes so secured together is supported in the center of the casing, so as to leave a space between the same and the bottom of the casing 1 by suitable supporting-pieces 9. The carburetingtubes are provided with an upper imperforate top portion and for a short distance up from the bottom and in the bottom with numerous perforations 10. Such tubes 6 are of such length that a considerable space-say from one to three inches, according to the size of the carbureteris left between the same and a bottom plate 11 of the fluid-chamber 12, which holds the carbureting fluid, such fluid-chamber being provided with an orifice'13, covered with a screw-cap.

14 for the insertion of such carbureting fluid therein.

' Incommunication at the top with the fluidchamberlzZ at the bottom'thereof area numberof small pipes 15, one for each of the carbur'eting-tubes 6,which extend down into such carbureting-tubes 6 a short distance and are in communication with such carbureting-tubes by way of numerous small perforations 16, such tubes generally being about one-third the length of the tubes 6, and within the tubes 6, filling the same from the bottom to the top and surrounding the perforated lower end portion of the small tubes 15, is a filling of any absorbent material, such as small pieces of sponge, adapted when the chamber-12 is filled with the carbureting fluid to be thoroughly saturated therewith by the drippings from the perforated pipes 15, so as to hold the samein suspension in the carbureting-pipes 6 and prevent'the dropping of the same down into the bottom of the casing. It will be seen that, the chamber 12 having been so filled with a suitable carbureting fluid, after a few minutes the absorbent material 17 will be thoroughly saturated therewith, and that if then air or gas be forced through the inlet-pipe 3 the same in its passage through the interstices or spaces 18 between the tubes 6 and by the bottom thereof will be broughtintointimate contact with the fluid oozing out through the perforations 10 in the tubes 6 and with the vapor issuing constantly therefrom, and that by reason of the tortuous path which such air or gas is compelled to take to reach the outletpipe 5 and the great amount of surface of saturated absorbent material presented to the air in such passage a much larger quantity of air can be thoroughly carbureted in a given length of time with a carbureter'of much smaller size than is usually the case.

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

1. In a device of the class described, the combination with an exterior casing, divided into an inner chamber, an inlet-chamber, and an outlet-chamber, of an inlet-pipe in communication with the inlet-chamber, an outlet-pipe in communication with the outletchamber, a plurality of carbureting-tubes provided with perforations at the bottom supported within the inner chamber, and separated by air-spaces, an absorbent material filling the carbureting-tubes, a fluid-chamber for holding the carbureting fluid located above the carbureting-tubes, and a tube provided with a plurality of perforations in the lower portion in communication at the upper end with the fluid-chamber at the bottom thereof extending down into each of the carburetingtubes, substantially as shown and described.

2. In a device of the class described, the combination with a plurality of upright carbureting-tubes open at the top and provided at the bottom and lower sides with perforations supported adjacent to one another so as to leave air-spaces surrounding such tubes, of a fluid-chamber located above the carburetingtubes, a plurality of tubes in communication with the bottom of the fluid-chamber extending down into the carbureting-tubes and in communication therewith by a plurality of perforations, a filling of absorbent material in the carbureting-tubes, an exterior casing, and an inlet and an outlet pipe in communication with the interior of the casing, substantially as shown and described.

3. In a device of the class described, the combination with a plurality of upright carbureting-tubes open at the top and provided at the bottom and lower sides with perforations supported adjacent to one another so as to leave air-spaces surrounding such tubes, of a fluid-chamber located above the carburetingtubes, a plurality of tubes in communication with the bottom of the fluid-chamber extending down into the carbureting-tubes and in communication therewith by a plurality of perforations, a filling of absorbent material in the carbureting-tubes, an exterior casing, an imperforate air-baffling wall partially separating the inlet from the central portion of the device, and a like plate partially separating such central portion from the outlet, whereby the air is compelled to follow a tortuous path, substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of the subscribing witnesses, this 29th day of May, 1901.

ILLIAM WRIGHT.
