CARBURETINGAPPARATUS.

SPECIFICATION forming part of Letters Patent No. 743,085, dated November 3,' 1903.

Application filed February 9,

To all whom/ iz': Tir/ay concern:

Be it known that LWILLIAM KAHLE, a citizen of the United- States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Carburetin g Apparatus and I do hereby declare that the following is a full, clear, and exact description of the same, referencebeing had to the accompanying drawings, and to the letters of reference marked thereon, which form a par of this specification.

This invention relates more particularly to an apparatus for generating a hydrocarbon illu minant gas,such as a mixture of vaporized gasolene or the like with atmospheric air.

The object of the invention is to provide a construction capable of rapidlyvaporizing a hydrocarbon liquid, such as gasolene, and mixing therewith atmospheric air in proportion suitable for illuminating purposes.

It is also an object of the invention to provide as compact and simple a construction as possible so devised as to efectually prevent the escape of the hydrocarbon vapor or` mixture therefrom except through the deliverypipe and adapted to be constructed of any preferred size capable of installation wherever a mixing and generating device of the class described may be required.

The invention consists in the matters hereinafter described, and more fully pointed out and dened inthe appended claims.

In the drawings, Figure l is a front elevation, partly broken away, of a device embodying my invention. Fig. 2 is a vertical section thereof parallel with the plane of the front and showing the fluid-elevator in elevation.

Fig. 3 is a section taken online 3 3 of Fig. 2.

Fig. 4 is a section taken online 4 ft of Fig. 3. Fig. 5 is an enlarged transverse section of the vaporizing and mixing drum. Fig. 6 is a fragmentary longitudinal section of the same. Fig. 7 is an elevation of the ends of the same, partly broken, and the fluid-elevator. Fig. 8

is a detail of one of the buckets on the chain elevator, illustrating its operation.

As shown in said drawings, the apparatus is contained within a cabinet A, adapted` to protect the same from interference and to afford support for the operating parts thereof, and comprises a closed hydrocarbon-sup- 1903. Serial No. 142,639. (Nmodel.)

ply tank B, a gasometer C, having a carbureter D therein. The supply-tank B cornmunicates with the gasometer through a pipe b. A blowing and regulating device E is provided,and a motor F of any desired or convenient natureas shown a weightmotor-operates the mechanism. As shown, said gasolneter C comprises an upwardly-opening tank or receptacle of sheet metal c, having a semicylindric lower end and having the upper edge flanged outwardly, as indicated at c in Figs. 2 and 3. Secured on the outer side of said tank C is an outer casing c2, having the upper margin thereof flanged inwardly, and which provides between the same and the tank C a space to contain water, thereby forming a water-jacket. Supported on said tank C, with its margins extending downwardly between the walls of the tank and the casing czinto the water therein, is the inverted bell C. The top of said cabinet acts to limit the upward movement of the bell when filled with gas, thereby compressing the gas or mixture therein before the lower margins of the wall thereof can be elevated above the surface of the water in the waterjacket. For convenience, if preferred,rollers c4 may be provided in said water-jacket, supported upon either the walls of the tank or casing, and which act tosteady and direct said bell as it rises or falls with the varying gas-pressure within the gasometer.

Within thecabinet and forming a support for the gasorneter is the cylindric casing e of the blower E. Said casing contains within ing and mixing or carbureting device, (indicated as a whole by D.) Said carbureter, as shown, consists of a sheet of met-al d, corrugated transversely and rolled to a spiral form, as shown in Figs. 2, 5, and 7, forming, as shown, a cylindric shell corrugated longitudinally and having a spirally-rolled interior portion, the inner end of said spiral terminating at the central shaft d2 and is secured thereto. Said carbureter is provided IOO at the ends with flanges d3, projecting beyond the edges of the sheet forming the spiral, as shown in Fig. 6. As shown, the periphery of the carbureter is provided with a plurality of apertures elongated longitudinally of the same between the corrugations, and on one side of each is provided a downwardly-turned lip d against the current of .f of which leads to a similar sprocket-wheel on the end of the shaft of the carbureter where the same projects through the gasometer-tank, thereby rotating the carbureter. The blower is rotated from the shaft of the carbureter by means of suitable sprocketwheels and sprocket-chains, as shown in Fig. l, so that by the gravity of said weight the carbureter and blower are simultaneously operated. The liquid in the blower-chamber by its resistance to the fan acts to regulate lthe descent of the weight and the rotation of the carbureter.

The gasolene or other hydrocarbon tank B may be of any desired form or size and, as shown, is located within the cabinet and provided with a delivery-pipe b, which communicates through the shell of the gasometertank near its bottom to a point below the carbureter, thereby permitting the fluid hydrocarbon to flow into the gasometer-iank ordinarily through a passage, which may of course be valved, or providing other means for regulating the delivery therethrough, as preferred. Said gasolene or other hydrocarbon fuel is elevated from the bottom of the gasometer-tank and delivered into the central portion of the carbureter by means of the chain elevator D, which, as shown, is provided with buckets d4, which are closed on all sides except along a comparatively narrow aperture near the outer edge of the bucket, as shown in Fig. 8. vator-chain is driven by the rotation of the carbureter eachof the buckets scoops up a portion of the hydrocarbon fluid and carries the same to a point above the carburetershaft and pours the same into the trough D2,

' as shown in Fig. 6, which delivers the same into the carbu reter at a point near the center.

A delivery-pipe b is provided leading from the gasometer outwardly to the system of distribution, and, as shown, the inner end of said pipe is provided with an upwardly-turned elbow extending sufficiently high Within the gasometer to prevent any of the liquid hydrocarbon finding its way therein.

A fillingpipe b2 communicates with the closed supply- As the said ele-- reservoir. Obviously any variety of indicating devices-such as gages, glasses, cocks, or the likemay be used to indicate the level of the fluids in the various portions of the de- Vice.

The operation is as follows: The device, constructed as described and having a sucient amount of Water in the Water-jacket surrounding the gasometer to prevent escape of gas therefrom and having the blowerchamber partly filled with water, as indicated in Fig. 2, `is started in operation by winding up the weight F, whereupon gravity of the weight causes the rotation and operation of the blower and carbureter, forcing atmospheric airinto the gasometer-chamber against the apertured side' of the carbureter as the same revolves. The liquid hydrocarbon flowing into the bottom of the gasometer-tank from the tank B is scooped up by the buckets of the chain elevator and carried over the shaft of the carbureter and poured into the spout D2,'flowing therefrom into the carbureter, near the middle thereof. As the carbureter is revolved the air from the pipe E/ passes inwardly through the shell of the carbureter, following the spirals, and becomes thoroughly mixed with the vapor of the hydrocarbon, which is violently agitated as it flows over the corrugations along the spirals. The mixed vapor or gas ilows outwardly at the ends of the carbureter into the gasometer, producing gaseous pressure therein and lifting the bell in a familiar manner, and as the upward movement of the bell is limited by the top of the cabinet the pressure therein augments, thereby resisting the inflow of hydrocarbon from the supply tank. The mixture of hydrocarbon gas and air may now be used in the usual manner for combustion, illuminating, or Yother purposes, the same flowing outwardly from the tank of the gasometer through the delivery pipe. Obviously the descent of the weight may be regulated very perfectly by the amount of fluid orliquid in the blower-chamber and the number of paddles and the Obliquity of the paddles with respect to the surface of said liquid. Other regulating means, however, may be employed, if preferred, and any motor or desired source of power may be utilized, as preferred. Obviously the flow of the hydrocarbon fluid into the gasometer-tank is automatically regulated by the means of the pressure within the gasometer, the flow being decreased as the pressure augments and of course increased as the pressure is exhausted.

The apparatus embodying my invention may be constructed of any desired size and the parts may be differently assembled with respect to each other and many details of construction may be varied without depart- -ing from the principles of this invention.
