To all whom it may concern:

Be it known that I, BENJAMIN ALFRED GUY, whose full postal address is Villa dOrlans, N euilly-sur-Seine, France, have invented certain new and useful Im provements in Oil-Feeds for Carbureters, of which the following is a specification.

The pressure of hydrocarbon vapor is very variable with the temperature, and as the carbureters at present employed do not take this into account they cannotmanufacture a carbureted gas of fixed composition and are therefore unsuitable for any serious industrial application.

Now this invention has for its object to pro- Vide an apparatus of simple and efficacious working in which the supply of the hydrocarbon is regulated by a distributer having the peculiarity of not possessing any joint, such as a stuffing-box, or ground-surfaces or any constant-level vessel,the working of which is defective by reason of the great fluidity of spirit and the variable pressure of its vapor. This distributer is actuated by the gas-meter itself, which insures a constant relation between the quantity of hydrocarbon sent into the carbureters and the quantity of gas used.

In the accompanying drawings, Figure 1 is a transverse section on the line X X of Fig. 2 of the hydrocarbon-distributing apparatus, and Fig. 2 is a longitudinal section on the axis of Fig. 1.

The hydrocarbon-distributing apparatus comprises a cylindrical reservoir a, mounted on a hollow shaft d and divided into two parts by a diametrical partition I), having an index 0 on the outside in order to-indicate the position of the partition. The hollow internal part of the shaft d is also divided longitudinally into two parts by an internal partition 9, and holes e and f serve, respectively, for

' enabling the chambers of the cylinder a to communicate with the interior of the shaft d. On the other hand,the hollow shaft d communicates by one of its ends with a tap rof suit able construction to enable liquid to be introduced at will into any one of the two compartments of the reservoir a. At the other end the hollow shaft cl discharges into a box 2', from whence it discharges the hydrocarbon which passes from there by a pipe j into carbureters 1 2 3, shown diagrammatically in the drawings.

The cylindrical reservoir a is carried by its shaft,on the one hand,on the box 2'- and, on the other hand, on a bearing 2., and it revolves simultaneously with its axis. This rotary move- 7 ment is imparted to it by a toothed pinion is, operated by a worm Z, fixed at the upper end of a vertical shaft, which is itself operated from below by a worm-wheel m, gearing with a worm 17, mounted on the shaftp of the drum of a meter 0. The drumof the meter 0 is only partially shown, and the meter is not described, as there is nothing special in its construction.

The cylindrical reservoir 60 is placed in communication with the carbureters l 2 3 by the hollow shaft 01, box 6, and pipe The distributing apparatus 8 has internally a small horizontal grating which distributes the liquid over the three carbureters.

The working of the apparatus is as follows: The hydrocarbon is introduced by the tap 1" into one of the compartments of the reservoir so as to completely fill same, which is located in the lower part when the partition 6 is horizontal. In consequence of the rotation of the cylindrical reservoir a, which rotation is imparted to it by the shaft of the drum of the meter, the partition I) is inclined and forces the hydrocarbon to escape by a hole f in the hollow part of the shaft cl, from whence it is discharged through the box 2', pipe and distributing apparatus .9 into the carbureters l 2 3. The rotation of the cylindrical reservoir a being operated by the shaft of the drum of the meter, it is evident that its angular displacement is proportionate to the quantity of gas recorded by the meter, from whence it follows that the quantity of hydrocarbon which it discharges into the carbureters is proportionate to the quantity of carbureted gas consumed.

It must be noted that the cylinder 8 revolves very slowly, (about one thousand times slower than the drum of the meter,) so that the level of the liquid cannot be superior to the horizontal plane which passes through the aperture f. The consequence is that half the cylinder is completely emptied in a half-revolution and that the flow is thus quite proportionate to the rotation. The necessary time for effecting this half-revolution is about one day. It depends on the proportions of the volumes of the cylinder (0 and the meter and the proportions of speed between this cylinder and the drum of the meter. This interval of time is calculated in such a way that, on the one hand, the volume of the cylinder at is not too great and, on the other hand, it is unnecessary to refill too often.

The moment one of the halves of the cylin der a is emptied it is replaced by the other half and the former half is refilled, and so on. Having now particularly described and ascertained the nature of the said invention and,

in what manner the same is to be performed, I declare that what I claim is- 1. In a distributer of oil for carbureters actuated by the gas-meter the combination of a cylindrical reservoir divided into two parts by a diametrical partition with a hollow shaft divided longitudinally into two parts having holes for enabling the chambers of the cylinder to communicate with the interior of the shaft and the means for introducing and discharging the liquid and the means for rotating the cylindrical reservoir as substantially described.

2. Ina distributer of oil for carburetors thecombinationof a cylindrical reservoir divided into two chambers communicating respectively with the interior of a hollow shaft divided into two parts, the said shaft having a tap at one end for introducing the liquid at will into any one of the two compartments of the reservoir and a box at the other end for discharging the liquid into evaporators as substantially described.

3. In a distributer of oil for carburetors the combination of a cylindrical reservoir divided into two chambers communicating respectively with the interior of a hollow shaft divided into two parts, the said shaft having a tap at one end for introducing the liquid at will into any one of the two compartments of the reservoir and a box at the other end for discharging the liquid into evaporators and for rotating the cylindrical reservoir a toothed pinion mounted on the hollow shaft gearing with an endless screw fixed at the upper end of a vertical shaft having at the lower end a wheel gearing with an endless screw mounted on the shaft of the drum of the meter as substantially described.
