IMPROVEMENT INCARBURETERS.

Specification forming part of Letters Patent No. 111,1

75, dated January 24,1871; reissue No. 6,079, dated September 29, 1874; application filed October 23, 1871.

To all whom it may concern:

Be it known that I, HENRY ALBERT CHA- PIN, of the city, county, and State of New York, have invented a new and useful Improvement in Garburetin g Apparatus, of which the following is a full, clear, and exact description, reference bein g had to the accompanying drawing forming part of this speeincation, and .which represents a sectional elevation of a carbureting apparatus having my improvement applied to it.

My invention, which is mainly designed for the carbureting of street-gas, consists in a novel combinationwwithin the carbureter, of the regulatingvalve and its connections, for controlling the discharge of the liquid from the reservoir to the carbureting chamber, whereby said valve may be adjusted from the exterior without making a break in the walls of the carbureter, thereby reducing the risk of accident by leakage.

The invention also consists in a certain combination, with the tank or reservoir, of a chamber provided with a sealed lid or cover, in combination with the valve, by which the supply from the tank to the carbureting-chaiiiber is regulated and made capable of operation from within said sealed chamber, whereby further protection against accident from leakage is obtained; also escaping vapor retained within the carburetcr.

The invention likewise consists in a combination, with said sealed chamber, ofthe several pipes or attachments connected with the supply and draft of the liquid to and from the tank and earbureting-ehamber, for the purposes already cited, and so that, on opening the sealed chamber, the various attachments or connections are exposed for inspection, adjustment, or repair. Y

The invention also consists in a combina tion, with the pipe which carries oli' the carbureting-gas from the apparatus, of a pipe or connection itted with a cock or valve, and establishing communication between said gaspipe and an airescape pipe or opening in the upper portion of the tank, whereby any condensed air and vapor with which it may be charged, produced in illing the tank, may be discharged into the gas-pipe.

The invention also comprises, in combination with an outer water or safety jacket, an interposed vair-circulating rchamber between said jacket and the earbureter proper, which it ineloses, said chamber essentially di'ering from a confined airspace by being provided.

' with suitable openings or ducts, `to provide for a free circulation of air through it, and for carrying olf as rapidly as formed any vapor leaking into said chamber, or otherwise avoid ing any excessive and dangerous accumulation of vapor therein.

Referring to the accompanying drawing, A represents the tank or reservoir of the apparatus, into which the earbureting-liquid is entered andA drawn off therefrom, or surplus and refuse removed, as required, by means of a tube, b, arranged to project through the top of the tank down to nearly the bottom thereof. To ei'ect the filling of the tank A, an air-y escape or vacuum-tube, c, may also be used, the same being likewise arranged to project .through the top of the tank, but Vonl)T entering to a limited distance down within it. 'I hese tubes b and c may be vprovided with suitable cocks or valves on their exterior or upper pro-l jecting ends, and be connected, respectively,

by supplementary pipes with a dip-pipe and. pump, attached to or forming part of a filling-` can, so that the pump may lirst be worked to produce a vacuum within the' tank A, and at'- terward to force 'the liquid from the can into the tank. This provides for the charging ot' the tank in a rapid manner7 and from a level which is considerably below the tank; also for the drawing oft of the liquid or refuse, when required.

Any other filling and drawing-off means, however, may be employed, and in some cases the tube c be dispensed with; or, Vwhen used, instead of operating as a vacuum-pipe in connection with a pump it may, under a different j inode of filling, be employed as an escape-pipe for condensed air, produced in the upper portion ot' the tank during the process of illin g.

In such case I connect such tube c by a pipe or connection, m, having a cock or valve, with the pipe c, which carries oft' the carbureted gas into the building. By this connection 'In all condensed air and vapor 'with which it may be charged is passed oi into the pipe e for use along with the gas. B is the carburetin g chamber, and d the gas-inlet pipe, which latter, together with the gas-outlet pipe e, is like- Wise preferably disposed to run up through the tank A. Projecting up Within said tank are also the draw-oit' pipe f from the carbureting-chamber B, and the supply-tube g thereto, and connection by which the regulating-valve h is operated to control the supply of liquid from the tank A to the carbureting-chamber. I is a float-indicator, for ascertaining thelevel of the liquid in the tank. Said indicator, like the tubes b and c, the draw-off pipe f from the carbureting-chamber B, and the regulatingvalve h, which controls the supply to the latter, are all in communication with and accessible from a chamber, (l, arranged on top of the tank, and provided with a lid, D, which is sealed, as by a glycerine, mercurial, or other yiluid joint, i. The arrangement of the regulating-valveh and its connections all Within the carbureter proper, and Without makinga break inits Walls or surrounding chambers to eiect the adjustment of the valve from the exterior, is au important feature in vthis invention, inasmuch as it reduces theliability of leakage, while the connection of the same, and of the filling land drawing-off attachments and indicator all within the chamber U, under cover of the sealed lid, as described, not only retain vapor leaking past said attachments or con nections Within the carbureter proper, but provide for a ready accessibility to said connections by simply removing the sealed lid D. E vis a safety Water-jacket or chamber surrounding the Whole structure, and F an interposed air-circulating chamber or space between said Water-jacket and the carbureter proper, to form anaddition-al safeguard. This air-chamber iusulates, as it were, the carbureter, the same being arranged around its sides and bottom or bottom and-top, and the Water-jacket E similarly insulates said airchamber, which latter is provided with vents or pipes k k, that in connection with an opening, l, made in the top of the Water-case, serve to keep up acirculation of airavithin the chant ber F. This provides for the carrying oi' of any liquid or vapor that might escape from the carbureter into said chamber, instead of allowing it to accumulate for mixture with a xed supply of air till a dangerous or explosive condition is reached.

What is here claimed, and desired to be se cured by Letters Patent, is-

`1. The combination, With the tank or reservoir A and carbureting-chainber B, of the valve h, by which the supply of liquid from the former to the latter is regulated, said valve and its Working device or connections being arranged Within the carbureter or tank thereof', and made capable of operation from the exterior, Without a break in the walls endangerin g leakage of liquid from the tank to the exterior of the carbureter, substantially as specified.

2. The combination, with the tank A, of the chamber C, provided With a sealed lid or cover, as described, and the valve by which the supply from the tank to the carbureting-chamber is regulated and made capable of operatioxr from Within the sealed upper chamber C, substantially as specified. p Y

3. The combination, with the sealed upper chamber, of the several pipes or connections by which the liquid is supplied to and drawn from the tank A and carbureting-charnber B,

essentially as herein set forth.

4. The combination, with the gas-pipe e and air-escape tube c, of the connection m, substantially as and for the purpose herein described.

5. The combination, with the carbureter and with an outer Water-case or jacket, E, of an air-circulating space or chamber, F, provided with vents or ducts, substantially as and for the purpose lorpurposes specied.
