CARBURETIER.

Specification of Letters Patent.

Patented Nov. 21, 1911.

Application filed May 20, 1910. Serial No. 562,370.

To all whom it may concern Be it known that I, JoI-IN O. BARDILL, a citizen of the Unlted States of Amerlca, residlng at Herculaneum, 1n the county of Jefferson and State of Mlssouri, have mvented certaln new and useful Improvements in Carbureters, of wh1ch the followlng 1s a full, clear, and exact description, reference being had to the accompanylng drawings, forming part of this specification.

My invention relates to carburetors and more particularly to that type of carbureters used upon motor vehicles, the invention having for its object the product-ion of a carbureter of simple construction whereby the vapor derived from a volatile hydrocarbon oil may be more efficiently and uniformly acquired during the operation of the carbureter than in the use of carbureters heretofore made, and also whereby the production of vapor may be readily governed to suit the needs of an explosive engine, that is supplied from the carbureter, accoiding to the speed at which such engine is operated.

Figure I is a top or plan view of my carbureter. Fig. II is a vertical longitudinal section. Fig. III is in part an end elevation and in part a vertical cross section, the gear housing being omitted. Fig. IV is an e11- larged cross section through the carbureter at the location of the mixing chamber and the controller valve governing the delivery of volatile oil to the mixing chamber. Fig. V is a perspective View of the controller valve. Fig. VI is a diagrammatical view of my carburetor and an engine supplied from the oarbureter.

In the accompanying drawings, and referring first to the diagrammatical View, Fig. VI :A designates my carbureter and B an explosive engine adapted to be supplied with vapor from the carbureter, and which may be delivered from the carbureter by a pipe 0. The carbureter is operated in harmony with the operation of the explosive engine and there is, therefore, a driving connection D, such as a belt, operable by the engine and through the medium of which a certain movable part of the carburetor is actuated, as will hereinafter fully appear. 1 designates the shell of my carbureter which is preferably in the main of cylindrical shape, and includes at one end a head 2. Within the shell is an oil chamber 3 to which a volatile hydrocarbon oil, such as gasolene, may be supplied, the means shown in the drawings for the supply comprising a float chamber 4 into which the oil is delivered from a suitable source and from which it is conducted to the oil chamber 8 by a pipe or conduit 5. In order to maintain a balance of oil in the oil chamber 3 and the float chamber 4L and prevent the production of an air pressure which is not in equilibrium with air pressure in float chamber in the oil chamber 3, I provide a pipe, or suitable connection, 6 that leads from the float chamber at a point above the level of oil therein to the oil chamber 3 at a point above that at which it is desired to maintain the level of oil in the last n1entioned chamber. 7 designates a revoluble drum located in the oil chamber 3 in the shell of the carbureter and which is preferably peripherally surrounded by a covering 8. The covering may be, and preferably is, of any suitable absorbent material, such, for instance, as felt. The drum 7 is adapted to turn in the supply of oil maintained at the bottom of the chamber 3, in order that oil may be gathered at the periphery thereof and the drum is so mounted in the oil cham' her 8 as to provide for its periphery riding in close contact with the upper portion of the wall of said chamber, as clearly illustrated in the drawings. The drum is supported and operated by means to be hereinafter particularly set forth. 9 designates a mixing chamber housing extending longitudinally of the shell of my oarbureter and within which is a mixing chamber 10. Alongside of the mixing chamber housing is a controller valve housing 11, in the inner portion of the wall of which is a slot 12 that leads through the shell 1 and furnishes communication between the interior of the valve housing and the oil chamber 3 in the shell, in order that air may enter the open end 13 of the valve housing, (see Figs. III and IV), and by passing through said slot reach the periphery of the drum 7. The exposure of the peripheral surface of the drum is regulated by a controller valve in the valve housing 11 to be presently described. The inner portion of the mixing chamber housing, or in other words the shell 1 at the location of the housing, is provided with a slot 14 that is adapted to register with the slot 12 in the wall of the controller valve housing and such registration is governed by the controller valve, as will hereinafter fully appear. 9 and 11 are, respectively, extensions of the mixing chamber housing 9 and the controller valve housing 11, these extensions being preferably carried by the head 2 of the shell 1. l5 designates the controller valve hereinbefore referred to, said valve being movable at an angle to the path of movement of the oil gathering member. This controller valve is slidably arranged in the valve housing 11 and it is provided with a tongue 16, (see Figs. IV and V.) The tongue of this valve extends longitudinally of and laterally from the valve into and through the slot 12 in the wall of the controller valve housing and said tongue also spans the slot 14 in the inner portion of the wall of the mixing chamber housing 9.

In order that the tongue may fit snugly to the periphery of the drum 7, the tongue is provided with a curved face 17 which spans the space between the slot 12 and the edge of the slot 14 farthest removed from the slot 12. The controller valve governs the admission of air into the slot 12 from the controller valve chamber and the tongue of the valve serves to regulate the amount of peripheral surface of the drum 7 that is exposed at the location of the slots 12 and 1A in the valve and mixing chamber housings and from which surface vapor is derived, due to the exposure of the volatile oil and the passage thereover of the air that enters into the controller valve housing. In traversing the exposed peripheral surface of the drum, the air picks up the oil on such surface and carries it into the mixing chamber 10. As small a percentage of peripheral surface of the drum as may be requisite to the demands of the carbureter may be ex posed by the adjustment of the controller valve so that only a very slight portion of such surface may be illustrated, as illustrated in Fig. IV, and when the demand is greater, the controller valve with its tongue may be adjusted to suit the greater requirement until, if necessary in fulfilling the requirement, the entire length of the drum is exposed at the

slots

12 and 14. It is to be noted that whatever may be the adjustment of the controller valve, the requisite amount of air is admitted through the slot 12 and exposure of the requisite area of surface of the drum is obtained with the result of the air being permitted to gather oil from such area in the proper proportion for satisfactory carburization. The

housing extensions

9 and 11 serve as closures for the rear ends of the mixing chamber and controller valve housings into which the controller valve and its tongue move in providing for intake of a proper amount of air and the exposure of the desired degree of peripheral surface of the drum 7 at the location of the slots 12 and 1A, in order that an explosive vapor may be acquired by the passage of air over such surface. The controller valve 15 is provided wit-h a valve rod 18 that extends through the open end of the va ive housing 11 and is adapted to be united through the medium of a connecting rod 19 with the throttle lever by which the operation of the engine supplied from my carbureter is controlled.

The revoluble drum 7 of my carbureter is supported by a shaft 20 operable in suitable bearings, and one end of this shaft extends into a gear housing 21. This end of the shaft has fixed to it a spur wheel 22 that meshes with a pinion 23 carried by a drive shaft 24 that is supplied exterior of the gear casing with a pulley 25, to which the driving connection D leading from the engine B extends to operate thereon and provide for the operation of the revoluble drum of the carbureter in harmony with the operation of the engine B.
