CARBURETER.

SPECIFICATION forming part of Letters Patent No. 659,476, dated October 9, 1900.

Application filed August 19; 1899. fiell'al 7 :3 6- (N0 mOdBL) To (LU whom it may concern:

Be it known that I, ALBERT EDWARD HOD- DER, a subject of the Queen of England, residing at Lon don, England, have invented certain new and useful Improvements in Carbureters, (for which I have made application for Letters Patent in Great Britain under No. 10,439, dated May 17, 1899,) of which the following is a specification.

This invention relates to the manufacture and distribution of gas for lighting and heatin g and comprises a power-station,from which air is forced along mains through the district to be illuminated. From these mains branch pipes are led to the various installations in the system. A generator is provided at each installation and comprises two or more concentric annular oarbureting-chambers, each connected to the air-supply main by means of a conduit provided with a cock in order to independently regulate the amount of air passing to each chamber. Hydrocarbons of different specific gravities are employed separate from each other, each hydrocarbon being allotted its own chamber. By the separation of the hydrocarbons and by the arrangement of an independent air-supply to each the proportion of carbureted air obtainable from each chamber can be adjusted so that the gas resulting from the mixture of these carbureted streams may have the quality or richness desired. An air-relief valve is provided upon the air-main adjacent to each generator in order that the pressure therein may not exceed a given maximum value.

In the accompanying drawings, Figure 1 isa vertical section of a gas-generator constructed according to this invention, showing the various pipe connections hereinafter referred to. Fig. 2 is a plan of the gas-generator, partly in section, on the line 2 2 of Fig. 1.

Like letters indicate like parts throughout the drawings.

The generator comprises a cylindrical vessel A, which is divided by means of two concentric cylindrical partitions B and G into two outer annular chambers A B and an inner cylindrical one C. This latter chamber 0 is provided with a perforated false bottom 0 situated a short distance above the com-' mon bottom A of the three chambers, while the two outer chambers A B are each fitted with spiral blades or vanes A B so arranged that air delivered into the bottom of either chamber will be forced to travel several times around it in a helical path through the liquid contained therein as it rises toward the upper end. The chamber 0 is filled with naphthalene, preferably purified naphthalene, resting on the perforated false bottom 0 The two outer annular chambers A B contain, respectively, a heavy hydrocarbon (such as petroleum having a flash-point at or about 120 Fahrenheit) and a light petroleum ether or benzin. The various chambers are filled through orifices provided at their upper ends and capable of being hermetically sealed by means of plugs A B 0 Compressed air is supplied from a central pumping-station through them-ain D and led through the branch pipes D D to the bottom of the chambers A B, respectively.

The pipes D D are continued up through the bottom A of the generator, as shown at D and D Their ends D and D are received in inverted stopped tubes E, which are perforated at their lower ends, as shown at E, the liquid in the space between these concentric tubes forming a liquid seal. Any other form of liquid seal may be used, however, or an ordinary non-return valve may be provided in the pipes D D The tops of the chambers A B are connected to the top of the chamber 0' by means of the pipes A B, and from the bottom of the latter chamber, a pipe leads to the burners. One or both of the pipes A 13 may be provided with a cock.

A loaded relief-valve F of any convenient construction is provided on the air-main D adjacent to each generator. The maximum pressure of air in the generator and of gas in the system may be regulated by varying the pressure on the valve F.

Hand-controlled valves G H are provided in the pipes D D and by means of these cooks the amount of air passing through the carbureting-chambers A B may be inde pendently controlled so as to regulate the richness of the resulting gas, as previously described.

In an apparatus such as described there will be two independent streams of air, one passingthrongh the chamberA and the other through the chamber 13. Thence being saturated with the vapor of the liquids contained in the two chambers A B the two streams unite in the central chamber 0 and become further enriched in passing through the purified napthalene contained therein. From the chamber 0 the gas isleddi'rect to the burners (which are fitted with incandescing mantles if the gas is to be employed for the production of light) by means of the pipe 0 Having now particularly described and ascertained the nature of my said invention and in What manner the same is to be performed, I declare that what I claim is 1. In an apparatus of thecharacter described, the combination with a series of carbnreting-chambers arranged one Within the other, of a series of spirallyarranged vanes within each of said chambers, an air-inlet pipe leading into each chamber below the vanes therein, and a carbureted-air-outlet pipe leading from each chamber above the vanes, as and for the purpose set forth.

2. In an apparatus of the character described, the combination with a carburetingchamber, of a series of spirally-arranged vanes therein, an air-inlet pipe leading into said chamber below the vanes, a carburetedair-outlet pipe leading from said chamber above the vanes, and a chamber adapted to contain an enriching agent into which the said outlet-pipe leads.

3. In an apparatus of the character described, the combination with a series of carbureting-chambers arranged one within the other, of a series of spirally-arranged vanes within each of said chambers, an air-inlet pipe leading into each chamber below the vanes therein, a carbureted-air-outlet pipe leading from each chamber above the vanes, and a chamber adapted to contain an enriching agent arranged within the innermost carbureting-chamber and into which the said outlet-pipes lead.

4:. In an apparatus of the character described, the combination with a series of annular carbureting-chambers arranged one within the other and spirally-arranged vanes in each chamber, of a central chamber, a perforated bottom therefor, an air inletpi pe leading into each carbnreting-chamber below the vanes therein, a carbnreted-air-ontlet pipe leading from each carbnreting-chamber above the vanes and into the central chamber, and an outlet-pipe leading from the central chamber below the perforated bottom thereof.

In testimony whereof I have hereto set my hand in the presence of the two subscribing witnesses.

ALBERT EDWARD I-IODDER. Witnesses:

GEo. M. BRUSHLIN, T. J. OSMAN.
