CHARLES E. PAGE, OF DETROIT, MICHIGAN.

CARBURETER.

To all whom it may concern:

Be it known that I, CHARLES E. PAGE, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Carbureters, and declare the following to be a full, clear, and exact description of the same, such as w1ll enable others skilled in the art to which it per tains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to carbureters, and has for its object an improved device of this type adapted to permit at the same ti me the easy and quick supply to the mlxmg chamber of a suflicient quantity of oil much more than is needed after the device has been properly startedfor initially forming a gaseous mixture, and at the same time providing for the complete control of the throttle mechanism and the automatic movement of the air inlet and vapor outlet parts.

In the drawings :Figure 1, is an elevation of the carbureter. Fig. 2, is a plan view of the top of the same. Fig. 3, is a sectional elevation of the device shown in Fig. 1, along the line aa of Fig. 2. F ig.. 4, is a sectional elevation along the line bb of Figs. 1 and 3at' right angles to the showing of Fig. 3. Fig. 5, is a sectional plan along the line 5 of Fig. 3.

A represents the usual float chamber, in which the float B is vertically movable, being mounted upon its stem C. The hydrocarbon is fed thereinto from beneath through a supplemental casing D, whose inlet aperture E abuts against the meshed strainer F, which is of cylindrical form, and spaced somewhat from the walls D. After passing through this gauze, and being thus rid of most of the impurities to be found in the liquid, it passes up past the valve G into the interior of the float casing A. Preferably integral with this is the casing of the mixing chamber H, which is connected with the chamber A by a passage J which is controlled by needle valve K. The metal immediately surrounding the delivery end of the passage J constitutes one of two oppositely disposed supporting lugs L, which b are preferably integral with the walls of the casing, and extend an appreciable distance toward the center of the chamber.

Screwed thereinto is the centrally apertured Specification of Letters Patent.

plug M, whose side portions opposite the end of the passage J are cut away as at J so as to permit the flow ofhydrocarbon thereto, and through the minute spaces between the shoulder N on the plug M and the edge 0 on the lug J. The upper edge of this shoulder portion 0 is inwardly beveled so as to constitute, in connection with. the adjacent portion ofthe plug M, an annular trough in which the hydrocarbon is exposed to the air entering through the bottom aperture P, and rising past the lugs L through the otherwise completely open annular passage R. Fixed with a screw attachment on the bottom end of the stem S which slidably engages through the plug M is an inlet valve plug T, which is so located along the stem, that, when it is atthe upper limit of its travel and engaging strongly against the bottom face of the central portion which is supported by the lugs L, its portion of greatest diameter (at its bottom) lies directly opposite the shouldersVof the casing.

Upon the upper portion of the stem S is located the vapor outlet valve member W, whose lateral shoulder portions Y fall short of even a frictional engagement with the nearest point of the adjacent casing wall to such a degree, that the area of the annular opening thus left between the shoulders Y and the casing wall is preferably about one-half the area of the annular opening left between the inlet plug T and the adjacent shoulder portion V at the bottom of the mixing chamber casing. The exact distance between the two members T and XV is thus maintainable and adjustable, and the position of their extreme lateral shoulders with respect to the 7 adjacent projections of the casing wall, both when the machine is throttled and when it is not, is thus provided for. Provision is thus made for exerting a strong pressure upon the outlet portion of the carbureter by causing the entering air to relatively be of such mass or volume, rather than merely a thin sheet of air, that, as it passes the parts where the hydrocarbon lies exposed, it more effectually absorbs and mingles it with itself.

When it is desired to flood the inlet chamer, in order to initially start the engine, this may be done by manually depressing the stem O upon which the float B is carried, thus causing the hydrocarbon to rise within the annular chamber about the plug mixture with the air entering from beneath,

and yet provides for the usual riddance from the carbureter of any surplus hydrocarbon which cannot be vaporized by the entering air through the medium of the space It, or about its central portion.

X is the usual needle valve whereby the float chamber may be emptied, when desired, for purposes of cleansing and the like.

What I claim is 1. In a carbureter, in combination with a float chamber, a mixing chamber connected therewith, a regulating valve for controlling the flow from one chamber to the other, an annular liquid-containing member in the mixing chamber in direct communication with the connection between the two chambers, a vertically movable throttle stem extending through said mixing chamber, and members adjustable relatively to each other carried thereby, whereby the space through which air is admitted into said chamber for mixture with the hydrocarbon therein exposed may be definitely proportioned to the space through which the mingled vapor is permitted to escape from the chamber, substantially as described.

2. A carbureter, having, in combination with a float chamber, a mixing chamber having a passageway extending therefrom to connection with the float chamber, manually actuatable means for controlling the passage therethrough, a vertically bored member suspended from the side walls of the mixing chamber in the central portion thereof, a liquid-containing portion thereof being in communication with the passageway between the two chambers, a stem member slidably engaging through said last named member, and closure members adjustably carried on said stem member, adapted to cooperate with adjacent portions of the wall of the mixing chamber in maintaining a fixedproportion between the size of the aperture therein through which air is admitted thereinto, and of the aperture through which the charged vapor escapes therefrom, substantially as described.

3. In a carbureter, the combination of a float chamber, means for regulating the character of the liquid admitted thereinto, an apertured mixing chamber connected with the float chamber, a centrally supported liquid-containing member in said mixing chamber, a throttle stem slidably engaging lengthwise of the chamber, and a plurality of members adjustable relatively to each other carried on said stem adapted to co operate with adjacent portions of the wall of the mixing chamber in maintaining a desired ratio between the size of the aperture in the chamber wall through which atmospheric air is admitted thereinto and that of the aperture through which the combustible vapor escapes, substantially as described.

In testimony whereof, I sign this specifi- Witnesses:
