CARBURETER.

Specification of Letters Patent. v

Patented June 22,1909.

Application med April c, 1907. serial No. 367,209.

.and HAROLD B.' ANDERSON, citizens of the United States, residing at Cleveland, ln the county of Cuyahoga and State of Ollio, have invented certain new and useful Illlprovements in Carbureters, of which the following is a specification, reference being had therein tothe accompanying drawing.

`This invention relates toimprovements in carbureters, for furnishing all explosive mixture to explosive engines, and pertains to the type which is made the subject-matter of our application #323,117, pending concurrently herewith, in which the slowly moving vol-y numes of air are subjected to an exposed body of volatile fluid for surface carburation, and the rapidly-moving volumes of air subjected to spray Carburation.

The object of the present improvement is to provide a deector within the air passage adjacent the exposed body of oil, and to control the movement of this detlector, whereby the carbureter is made capable of adjustment, and therefore adapted for regulation to suit the particular nlotor to wllich it is applied.

In the accompanying drawings, Figure 1, is a sectiollal view showing one form "of our. improvement. Fig..2, is a section at right allgles to Fig. l. Fig. 3, is a modification;

Referring now to the drawings, 1 isa fluid chamber in which there is located a float 2, and this float 2 controls an illlet valve 3 for the purpose of maintaining a Huid level in the chamber 1. The operation of this construction is so wellunderstood thatany further explanation of it is unnecessary.

An alr passage4 extends across the cllalllber 1 and has its end 5 communicating with the motor. The usual throttle or valve 6 may be used for controlling the passage of the mixture from tlle carbureter to the motor,

` and thereby controlling the motor.

As shown, the lower wall or bottom 7 oftheA air passa e 4 extends downward to a plane lbelow t e maintained oil level of the chamber 1andvis provided with an oil oriice 8 through `which the oilpasses from the chamber to the passage-way 4, and inthis way a body of vfluid is maintained within the passage-way for the surface carburation of the slowly moving volumes of air. The rapidity with which the oil is permitted to flow through the orifice 8 may be controlled bylneans of an adjustable valve 9.

It is desirable to have the slowly moving volumes of air directed close to the exposed body of oil in this type of carbllreter, and

for this purpose a deflector 10 is placed within the air passage and at a polllt at or ill front of the exposed body of Huid. As here sllown, this deflector is hinged at its upper elld, and is declined ill the direction of the air currents.

In the form shown in Fig. 1 the deector i is nlade of suflicient weight to maintain the position showll in Fig. 1 against the very slowly moving volulnes of all", as when the 'motor is out down and running very slow'. 'When necessary, the deflectoris provided fwith one or nlore portions 10'- to increase ,its weight. In this instance, the throttle 6 will be alnlost closed so that the current of air passino' through the passage-way will not be sucient to lift the detlector. To

permit air'to pass by the detlector itis rea In-this way the cessed as sllown at 11. slowlynloving volllllles of air are `caused to pass `close to and against the exposed fluid, and to be properly carbllreted. lVhen,

however, the throttle is open wider and the lllg as a spray carbureter, llleans is provided for regulating the distance that the defleotor shall swing opell. plished in many ways, and in Fig. l itis accol'llplished by means of anl adjustable nlelllber or screw 12 which passes tllrough the top of the air passage witll its inner end in the pat-h traveled by the defleetor. This provides a very simple means for controlling the opening action of the deflector.l

In Fig. 3 a modification is shown in whicll the deflector 10 is made Without any recess This may` be accomat its lower edge, and vits closing act-ion is controlled by an adjustable screw 13. In this way the dcflector is made adjustable .in respect to the slowly nlo'fing volumes of air, as well as ill respect to the rapidly moving volumes of air. In a carburetor having this'` principle the air passage can be so conslructed for a motor'of a given size that a deflector, or other controlling means, is not necessary, but when the carbureter is to be built for universal use (Within reasonable limits) then it is desirable to have means for adjusting the control of the passing currents of air. 1

It will be understood by those skilled in this art that an adjustable deflector can be constructed in various Ways, and wevdo not therefore desire to limit ourselves to the construction here shown.l

Having thus described this invention, what We claim and desire to secure by Let ters Patent, is

1. A carbureter comprising an air passage providedwith a fluid inlet orifice, means for maintaining a body of Huid within the passage by gravity feed through said orifice for slowly moving volumes of air, the oritice` being restricted to cause the rapidly moving volumes of air to suck and thereby spray the fluid drawn through said orifice,y a freely movable deflector in the air passage actu-g ated by the passing currents of air, and posi- Y tive limiting lneans positively controlling the opening movement of the deflector and the maximum air ca acity of said passage.

2. A carbureter of) the type described having an air passage, a deflector therein and sage by gravity feed through said orifice for slowly moving volumes. of air, the orice being restricted to cause the rapidly moving volumes of air to suck and thereby spray the fluid drawn' through said orifice1 a freely movable defiector in said air-passage opened by the passing currents of air, and an adjustable limiting means positively but adjust-ably controlling the opening movement of the delector and thereby adjust'ably con-` 5 'trolling the velocity of the air passing through said air-passage to adjustably control the surface and spray carburetion of dthe passing air.

In testimony whereof We atlix our signatures in presence of two Witnesses.
