The interior tube, B, is surmounted by an air inlet chamber, C, "which is closed when the device is not in operation by means of a valve, c c, which ts normally held to its seat by a fairly stiff spring. Within the float-chamber, D, is arranged an annular metal float of substantially the same specific gravity as the liquid, which is guided at its center by a standpipe depending from the cone F. The latter Is pierced by a horizontal, slightly flaring passage, cutting at right angles the standpipe depending into the float chamber. A needle valve, G, called the gasoline adjusting valve, is arranged in the horizontal passage and is adjusted according to the feed of liquid desired. The gasoline arrives from the tank, located at some distance above the carburetter, through the tube, B. Its entrance into the float chamber is controlled by an inverted, spring-pressed, conical valve. Every time that the level of the liquid in the float chamber is lowered, owing to the suction of the motor, the annular float, M, becomes Immersed to a lower depth, and bears on the small lever, d, which in turn forces the gasoline valve from Its seat. There is some difference in the action of the annular float, M, as compared with the usual carburetter float, as the float M Is hardly ever fully supported by the weight of the liquid it displaces, and begins to act only when its unsupported weight overcomes the pressure of the spring surrounding the gasoline valve. It Is claimed that owing to this arrangement the height of the fuel level in the float chamber is less affected by the vibration of the vehicle than in other carburetters. The gasoline drawn through the horizontal passage cutting the standpipe flows through the orifices of this passage to ooze in a thin sheet ...
