Application tiled February 19, 1909. Serialo. fl.

To all whom# may concern;

Be it known that I, WILLIAM K. BASS- roRD, a citizen of the United States of America, and resident of Perth Amboy, in the county of Middlesex and State of New Jersey, have invented certain new and useful Improvements in Carbureters, of which the following is a specification.

My present invention relates to a carbureter intended especially' for use on automobiles and motor boats, and for other uses to which it is adapted.

The main object of the invention is to dispense with all manually adjusting devices for regulating the supply of either the gasolene or air, and lto do this without increasing theV complexity of the construction.

lVithout defining the scopes of the invention which are attended to in the claim hereinafter annexed, myV general conception comprises a vane which is located'in the air current, and is movable to and fro according to the speed of the air, for automatically adjusting the effective size of the asolene port, in the side of a tube, insi e, of which slides a cylindrical valve which is attached to said vane. Then the speed of the motor is too great, the said valve automatically closes said port. The carbureter has a free passage at all times, for the air, and I provide means for adjusting the size of this passage, said ymeans consisting of interchangeable perforated partitions, with holes of diierent sizes.

The device for illustrating my conception is set forth in the accom anying drawing.

Fi ure 1 is a vertica sectional view of the evice, while Fig. 2 is a plan of the upper ortion of a part of the device for showing the air passage.

I will now describe what is shown in the drawing.

A is a casing, the u per portion of which constitutes the air cliamber, in which is located a vane J, movable downward by the pressure of the moving air, while a retractile spring T is provided for lifting the vane J, when the speed of the air dlmin-y ishes. The spring T is conveniently located on the stem V, to which the vane J is attached, and which asses through a bearing K, on the top of t e casing A, said sprin being between the bearing K and the a justable nut U, on the stem. A valve W projects below the vane J, and enters the gasolene nozzle E for varying the admission of the gasolene through the gasolene port H, in the nozzle E, Varying speeds of air through thev air chamber cause varying movements of the vane J, and consequently vtlrying supplies of the gasolene automatic- -a y.

` D represents a device for forming a stricture of the air passage. The restricted opening is the annular space X around-the gasolene nozzle E. I provide other stricture devices of different sizes, any one of which ma be inserted, according to the conditions un er which the carbureter iste work.

R is the throttle located in the pipe F for supplying the motor.

G represents the permanent air passage around the vane J, whereby the air passage isnever closed.

The other details shown, but having no direct bearing on the novelty, are the float chamber L, a float M, therein, a lever N for the ball valve O, a gasolene inlet P, and a primer Q. S is the pet cock for cleanin the float chamber. As these details are ol their operation need not be described.

The invention may be modified, in so far as the modifications fall under the claim.

The detailed operation of the means for regulating the supply of gasolene will now be set forth.

The throttle R i's'opened, and the air commences at once to pass through the openin at the top of the carbureter .at each side o the bearing K, and to enter the air chamber at the upper portion of the casing A. It then passes through the annular space around the vane J, then through the restricted passage atr-X, vand then into the engine bydpassing through the throttle port aroun the throttle valve R. In passing by the port H in' the tubular gasolen'e nozzle E, it draws out, by suction, gasolene, from the tank L, in the form of asolene va or. I 'purposely make the port Il, rectangu ar, as shown, so that if the valve W is-half way down, one half as much gasolene will be drawn out as if fully open, and similarly, for all positions of the valve- W, proportionate amounts of va or will be drawn out. As the speed of e air increases, the vane J will continue to descend, and when the speed is greater than desired, the port H will be completely closed, thus automatically, stopping the motor, or engine.

I claim as my invention,

In a earbureter, che combination of a oesing forming an air chamber, a tubular gas@ Iene nozzle, extending into said chamber, and having a rectangular port running along the side of the nozzle, a valve extend- 10 ing lnto said nozzle, for covering said port distance in the nozzle,

more and more in direct proportion to its and means governed by the air assing through said chamber for adjusting t e valve along the length of said port.
