.VCARBURETOR FOR ENRICHING GAS.
SPECIFICATION forming part of Letters Patent No. 351,858, datedv November 2, 1886.
Application filed April 19, 1886.
,attaching the apparatus to a service-pipe.
The apparatus is light and portable.
An apparatus of the class to which my invention pertains is illustrated in my Letters Patent No. 324,992, of August 26, 1885. In apparatuses of this class it is diilicult to regulate, once for all, the proportion of hydrocarbon vapor that should be supplied to the gas to produce the best illuminating effect, as this vapor increases in volume as the temperature of the hydrocarbon-reservoir increases, and when more carbon is supplied than can be consumed the dame becomes smoky. In my former patent I showed' means whereby I partially overcame the dificulty. 'Iheseconsisted f vide an improved automatic means for regulating the proportion of hydrocarbon vapor supplied to the gas, and this regulation I eiiect by maintaining a uniform temperature in the hydrocarbon-reservoir. I maintain this uniformity by means of a valve which automatically controls the. supply of gas to the heating- 4o jets, this valve being regulated by the expansion and contraction of metal, as will be hereinafter explained. I also by preference employ a similar]y-operatedvalve to regulate the proportion of the hydrocarbon vapor supplied tothe miXing-chambe'r. When this latter valve is employed, I also employ, by preference, the safety-valve described and claimed in my former patent.
It is not new with me to employ a valve operated by expansion and contraction to regulate the supply of gas to the heating-j ets of Serial No. 197,421. (No model.)
an apparatus for enriching gas. This hasbeen employed before in several forms, and I do not invention, Figure 1 is a vertical longitudinal section of my carburetor, taken in the planeindicated by line 1 1 in Fig. 2; and Fig. 2 is a horizontal section or sectional plan taken in the plane indicated by line 2 2 in Fig. 1.
A represents the hydrocarbon -reservoi r, which may be spherical or of any convenient form, and is usually made from sheet metal.
B is the mixingchaniber or reservoir,"where in the gas and hydrocarbon vapor are mixed before passing to the burners. This chamber may also have any convenient form. These two chambers or reservoirs may be connected in any convenient manner.
O is a tube which extends through both reservoirs and forms the gas-conduit. enters the upper end of tube O, which may be provided with a socket, m, for attaching it to a gas-service pipe. For convenience, instead of employing two tubes or pipes, one to admit the gas to the mixing-chamber and the other the mixing-chamber, and form an aperture or apertures, b., in the pipe above this plug, or between it and the gasinlet,and another aperture or-apertures, c, below or on the other side of said plug. In order to pass this obstruction,the gas must pass into chamber B through apertures b, and then back into the tube C at the apertures c.
' A conduit, d, which may or may notbe provided with a controlling-cock, c, leads the hydrocarbon vapors from the upper part of reservoir A to the mixing-chamber B. A safetyvalve, g, similar to that shown in my'former patent, is provided, to obviate danger from eX- cess of pressure in the reservoir A. This valve I do not consider essential to my apparatus as now constructed 5 but I prefer to em-' ploy itunder some circumstances.
On the lower or pendent end of tube C is a chamber, D, in which is formed a valve-seat, h, which divides the' chamber D intonan upper and lower section. From the upper section of the chamber project radially the branches E, one or more, which are provided with the illuminating-burners E. From the lower section of the, chamber D project radially the shorter branches, F, one or more, which are provided with the heating-burners F. These burners E F may be of the usual kind employed for gas. Then the gas is turned on and the burners lighted, the burners F heat the reservoir A and vaporize the hydrocarbon, preferably naphthaline, contained therein. The vapors pass up into the chamber B and mix with and enrich the gas therein. The gas thus carburetcd or enriched flows down the tube C to the burners.
In order to regulate the quantity of gas supplied to the heating burner or burners F, whereby a uniform or a nearly uniform temperature may be maintained in the hydrocarbon-reservoir, I provide the means I will now describe.
G is a disk-like valve, arranged in chamber D, and adapted to be moved toward and from the valve-seat h, which is annular and preferably of a V form. This valve is screwed on the end of a slender iron rod, H, which is arranged in the tube C, and attached at its upper end to the plug a, or to some other eonven ient part. To form a guide for the valve, a stem, t', attached to its back, is arranged to play in asocket in ascrew-plug,j, which closes the bottom of the chamber D.
The operation is as follows: Vhen the reservoir A and its contents become heated, the
tube C, which is usually of brass, expands in the direction of its length, and the rod H, usually of iron, not being exposed to the heat to the same extent as the tube, will not expand to the same extent. The result will be that the valve G, carried by the rod or stem H, will be brought nearer to thevalve-seat L, andtheliow of gas to lthe heating-jets F will be proportionately reduced.
By thc proper adjustment of the valve with respect to its seat while the apparatus is cold, it will be obvious that the expansion and contraction of the parts, as explained, will maintain a nearly uniform degree of heat in the hydrocarbon-reservoir. Theilluminating-jets are not affected by this throttling of the gas, as they are supplied from above the valve G; and it will be found, ordinarily, that the loss in general illumination occasioned by the throttling of the passage leading to the heating-jets will be made good by the increased supply thus afforded to the illuminatingjets E'.
In order to regulate the supply of hydrocarbon vapor to the mixing-chamber B, the controlling-cock e, set or adjusted once for all, will usually be found sul'licient; but when the heat in the hydrocarbon-reservoir becomes excessive and the pressure of vapor therein proportionately increased, the vapor will flow through conduit d more rapidly. As a precaution against this, I usually employ the device I will now describe.
On the upper end of the vapor-conduit d, I mount a valve-seat, k, and over this a disklike valve, J, secured to a branch, m, of slender iron rod I, arranged in the tube C. The arm m projects from the tube C through one of the apertures c, and the lower end of the rod or stem I is attached to the tube C at l, down near its lower extremity. The valve J serves to check the iiow of vapor through conduit d, when the reservoir A becomes too highly heated, and its operation is controlled by expansion and contraction, precisely like the valve G. The purpose in making the tube C of brass and the rod or valve-stems II and I of iron is that I may take advantage of the unequal expansion of these metals. The relative movements of the valves and their seats will be very slight, and therefore I make the valve-apertures quite large, as shown.
Although I have shown what I conceive to be the best form of my apparatus, I do not limit myself to the precise construction shown, as this may be varied to some extent without departing from my invention. AS distinguished from former apparatuses or devices for this purpose, I employ a thermo-regulator for controlling the supply of hydrocarbon vapor to the mixing-chamber, a valve-chamber and valve of special construction for regulating the supply of gas to the heating-burners, and I apply my thermo-regulator to a carburetor having a separate mixing chamber. These features I believe to be new.
The burner-tubes or branches E F maybe provided with the usual rcfulating-eocks, if desired. I have not deemed it necessary to show them, as I do not use them in every case. The opening` closed by plugj, in the bottom of chamber D, should be large enough to admit the valve G.
I claim as my invention- 1. 'Ihe combination, with the hydrocarbonreservoir and the mixing-chamber, connected with cach other by a vapor-conduit, of a therino-regulator and valve controlled thereby to regulate the quantity of vapor admitted to the mixing-chamber and a burner to heat the hydrocarbon-reservoir.

3. The combination, with the hydrocarbonreservoir, of the tube forming the gas-conduit, the chamber D on the lower end of said tube, and said chamber provided with a Valve-seat, 7L, the valve G and its long slender stem H, arranged in said tube and fixed at its upper end, the branch pipe E, for the illuminatingburner, connected with chamber D above the valve-scat 71 and the branch pipe F, for the IOO IIO
