CARB URETER.

Specification of Letters Patent.

Application filed March 13, 1907. Serial No. 362,159.

Patented July 4, 1911.

To all whom it may concern:

Be it known that we, ALEXANDER \Vix'roN and HAROLD B. ANnnnsoN, citizens of the United States, residing at Cleveland, in the county of Cuyahoga and Statebf Ohio, have invented certain new and useful Improve ments in Uarbureters, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to impncvements in carbureters, and is for. use in connection with explosive engines for supplying thereto a uniform explosive mixture for the various speeds of the motor, and involves the principle or" providing and maintaining a body of exposed volatile fluid within the air passage for surface carbura'tion of the volumes of air which are moving at low velocities (as when the motor is throttled down) and to carburate the rapidly moving volumes of air by causing the fluid to be sprayed therein.-

The objectof the present invention is to provide means for causing the slowly moving volumes of air to pass in direct contact with and close to the exposed fluid to insure the proper carburation thereof, but

. which will carburate the rapidly moving volumes of air by spraying the liquid therein.

A further object of the present invention is to provide means for regulating the quantity of slowly moving volumes of air which are permitted to pass through the air passage-way for the lowest speeds of the motor, whereby the device is adjustable, and thereby made adapted for use with motors of various sizes.

' In the accompanying drawings, Figure l, is a View of our improved carburcter, the air passage being shown in longitudinal section. Fig. 2, is an end view of the means for controlling the amount of slowly moving volumes of air permitted to pass to the motor for its slowest speeds. Fig. 3, is a face View of the deflector for the main air passage.

In carrying out the present invention, as herein illustrated, a fluid chamber 1 is pro. vided in which the fluid is maintained ata redetermined level, which is illustrated in Eig. 1 by dotted line, and the words Fluid level. Any of the well known forms of devices for maintaining a predetermined fluid level may be used, and therefore any further description of this mechanism is unnecessary.

A main or primary air passage 2 extends across the top of the chamber 1 and is in communication therewith through a fluid passage-way 3. The fluid flows by gravity through this passageway, and maintains a fluid level within the passage which furnishes a body of fluid within the said passage for the surface carburation of the very slowly moving volumes of air. The/rapidly moving volumes of air take up the fluid faster than it is fed to the passage by gravity, and it is then drawn into the passage-way by jet action and sprayedinto the rapidly moving volumes of air.

A deflector 4 is located in the passage 2, and placed with its lower end in front of but adjacent to the outlet end 5 ot' an auxiliary air passage-way 6, and also' infront of but adjacent to the fluid outlet 3. This deflector is pivoted at its upper end against the upper wall of the passage 2, as shown at 7, and freely swings upon its pivot. The passageway 2 is provided with rectangular walls to permit the swinging of the rectangularshaped deflector 4, and the dhflector tits within the passage sutlieiently tight to pre ventthe passage thereby of any appreciable amount of air.

The air inlet end of the auxiliary air passage 6 is provided with a slot or slotsS, and

placed over this slotted end is a rotatable slotted cap 9, whereby it can be rotated to more or less register with the slots 8. and thereby regulate the amount of air which is adapted to pass through the auxiliary passage.

cient to maintain thh po 'ition shown in Fig. 1. when the motor is hrottled down and the slowest volumes of air are required for its operation, and in this posit-ion the deflector closes the air passage 2 against any passage of air therethrough.

In operation the main air passage-way 2 is closed against the passage of the slowly moving volumes of air, and these pass through the auxiliary passage-way 6 and issue from the odter end 5 thereof in direct contact with the exposed body of fluid. hen the speed ofth'eg motor is increased, and more volumes of air are r'equirerhwhich cause themto movefaster, and when these volumes of -air have reached a suiflcient The deflector 4 is made of a weight snfliis lifted thereby more or less, according to the requirement of the motor, and thus furnishes, or rather, permits the proper I amount of air to pass to the motor.. Owing to the location of the deflector it causes the air to be-depressed, or directed toward and upon the exposed body of fluid, and toward the fluid outlet 3. When the volumes of air are sufliciently rapid and of a quantity which requires more 'gasolene for proper carburation thanpasses to the passage-way 2 by gravity, the exposed fluid is exhausted and ceases. to be maintained within the passage 2, and the rapidly moving volumes of air then suck the gasolene through the'opening 3 on the jet principle, which causes it to understood that this regulating device will be sprayed into the passing rapidly-moving volumes of air, and to effect a spray carburation thereof.

For motors of a given bore and stroke the amount of air allowed to pass through the auxiliary'passage-way is a fixed quantity,

and in such case any adjustment thereof is unnecessary. However, to adapt this present improvement for motors of diiferent sizes, and to thereby make the carbureter to a large extent capable of universal application, the auxiliary air passage is provided with the means heretofore described for regulating the size of the inlet thereto, and thus control the amount of air which is permitted to pass through the auxiliary passage-way before any is permitted to pass through the main passage-way. It will be control, to a large extent, the action of the deflector, for the reason that the air being .drawn by the motor will seek the course of the least resistance, and when more is required by the motor than is permitted to pass through the auxiliary passage-way, then the deflector will move and permit the additional required amount to pass through themain air passage, and in this way the adjustable feature of theauxiliary passage is a controlling means determining'the action of the deflector.

We do not limit ourselves to the details herein shown for carrying out the principle of operation disclosed, for with these-teachings and disclosures at hand other constructions adapted to effect the results herein set forth may be devised without departing fr'un the scope andspirit'of our present invention. Y

Having thus described our invention, wlr at we claim and desire to secure by Letters Patent, is :2

1. A carbureter comprising an air pasthrough the said passage for the purpose described. I

2. A carbureter comprising a main air passage provided with a fluid inlet, means for maintaining a body of oil in a plane above the inlet by gravity flow therethrough for slowly moving volumes of air, said inlet so'restricted as to require suction of fluid therethrough for rapidly moving volumes of air, means for closing the main air passage against the flow of veryslowly moving volumes of air, and an auxiliary air passage feeding air to the fluid independently of the said air controlling means for the main air passage.

3. A carbureter provided with a carbureting air-passage having a substantially horizontal portion, the bottom of the-hurlzontal portion having a fluid inlet a swing ing deflector located in the passage in rear of the fluid inlet and adapted to close the passage against slowly moving volumes of air, and an auxiliary air-passage having communication with the said horizontal portion of the carbureting air-passage at a polint between the deflector and said fluid in et.

4.. A carburetor having a main air-passageway provided with a fluid inlet, means for maintaining a body of oil in a plane above the said inlet by gravity flow therethrough for slowly moving volumes of air, said inlet so restricted as to require suction of fluid therethrough for rapidly moving volumes of air,.in combination with a movable deflector located at the rear portion of the maintained body of fluid and adapted to close the main passage against the flow of slowly moving volumes of air but actuated to open position by the rapidly moving volumes of ,air, and an auxiliary passage-way having an openinginto the main passage at a point beyond the deflector and adjacent the said flu1d inlet, and means for regulating the flow of air through the auxiliary passage.

In testimony whereof we afiix our signatures in presence of two witnesses.
