CARBURETER.

Application filed May 28, 1912.

To all whom t may concern.'

Be it known that I, ADAM R. HENDRIX, a citizen of the United States, residing at Chicago, in the county of Cook and State of linois, have invented certain new and useful Improvements in Garbureters for Internal-Combustion Engines or the like, of which the following is a description. y

My invention relates to that class of devices known as carbureters or mixers for iinely dividing a fluid hydro-carbon and discharging the same into, and thoroughly mixing the same with, a certain volume of air to form a combustible explosive mixture.

The object of my invention is to provide a device of the kind described which can be operated under substantially any conditions of weather or temperature, suitable for use with the more non-volatile liquid hydrocarbon and with' a certainty of the accurate and reliable operation of the device and the production of a uniform mixture.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described and more particularly pointed out in the claims.

In the accompanying drawings wherein like or similar reference characters indicate like or corresponding parts;

Figure 1 is a central vertical section of my device.

Fig. Q is a detail elevation of the controllingV mechanism of my device.

Fig. 3 is a fragmentary section taken substantially on line 3-3 of Fig. 2.

Fig. 4 is a section through the mixing tube of my device taken substantially on line 4--1 of Fig. 1.

In the form'shown in the drawings l is a tubular casing preferably of substantially uniform size its entire length with a fuel receptacle 2 rigidly secured on one side with a neck or stem 3. A port l extends from the interior of the receptacle 2 into the casing 1. The end 5 of the port adjacent the casing is conical, and a conical valve 6 is positioned in the casing and arranged to close the port. A stem 7 extends through the receptacle 2 with a hand wheel 8 or other convenient means upon its end for conveniently adjusting the position of the valve. A gland 9 or other suitable means is also provided to prevent the escape of fluid from the receptacle 2 adjacent the hand wheel.

Specication of Letters Patent.

Patented July 3, 191'?. Serial No. 700,313.

the receptacle reaches the point of overiiow the height of the fuel will be accurately maintained as long as a suiiicient amount of liquid is supplied. The overflow may of course, be connected to the main fuel supply tank or other convenient point that will per` mit the fluid to escape by gravity. A small vent pipe 12 is also provided in the top of the receptacle to prevent air imprisoned within the receptacle to interfere with the regular operation of the device.

rlhe casing 1 is preferably circular in section and provided with any desired number of butteriy valves or dampers 11k-15 adapted te control the flow of air through. the casing. The valve 1-1 is positioned substantially opposite the port l and the valve 15 is positioned slightly nearer to the discharge end of the casing. The shafts or axis of the valves extend `through the wall of the casing at one side and are each provided with a; crank, or handle 16 and 17 respectively so that the position of the valves in the casing may be accurately determined and adjusted by the position of the respective cranks.

In the preferred construction a link 18 connects the cranks 16 and 17 so that a movement of one will produce a corresponding movement of the other thereby providing for the simultaneous adjustment of the valves. Any suitable means may be provided for locking the valves in position. In the form shown a yoke or segment 19 is loosely mounted upon the shaft of the valve 14 between the arm 16 and the casing 1 with a suitably formed slot 20 in its periphery. The arm 16 preferably projects beyond the [ink 18 as shownand is provided near its extremity with a bolt or other convenient means extending into the slot 20 so that when desired the arm may be rigidly secured to the segment in any desired position. A link or rod 22 is pivotallyattached to the segment 19 and connected to the governing mechanism of the motor or if desired may be carried to any convenient point for manually controlling the position of the segment and thereby control the opening through the casing and the operation of the motor. 0b-

' The apertures viously if it is not desired to provide such automatic governing mechanism or to control the operation of the motor from a distanceJ the segment 19 may be rigidly secured to the casing 1 or if desired cast integrally therewith so that by securing the arm 16 to the segment the valves will be rigidly held until further adjuster.

The casing 1 is preferably entirely open at one end as at 2e while the opposite end is provided with a perforated plate 25 and connected beyond the plate 25 in any suitable manner as by the tube 26 to the cylinder or combustion chamber of a motor or other point where the mixture is to be consumed.

27 in the plate 25 are preferably angular as shown so that, in addition to operating as a strainer for preventing large pieces of material from being drawn into the cylinder' the plate 25 also serves as a mixer for further breakingup the larger globules of the liquid and more intimately mixing them with the air. A cap or cover 28 is provided for the end 1 to prevent dust and other foreign material from entering the casing and thus finding a direct passage to the engine cylinder.

In operation the desired liquid fuel is pumped or otherwise supplied through the pipe 10 to the receptacle 2 as soon as the receptacle is full, that is, as soon as the fluid begins to escape at the overflow 11 the hand wheel 8 may be operated to 'slightly open the valve 6 so that fluid will flow through the port with its conical part 5 into the casing 1 although under ordinary cir cumstances when the valve is sufficiently open for the proper operation of the device the fluid 4will be largely held by capillary action and will not flow to any considerable extent into the casing. When the engine is started however, the reduction in air pressure in the tube or suction of the engine is sufficient to draw the fluid rapidly through the conical space about the valve 6 thereby discharging the fuel into the casing in a fine spray. The larger globules are projected against one side of the bi'itterfly valve 14 and the remainder is carried down by the air and more or less distributed over the surface of the valve 15 and plate 25 so that the air rushing through the casing 1 is brought into intimate contact with the fluid upon the valves and operates to wipe the fluid from the valves and intimately inizi the sanie with the on rushing air. `The larger globules of fluid which may be thrown from the valve 14 are caught upon the valve 15 or the plate 25 and again broken up as it passes through the plate thereby producing an extremely intimate and substantially permanent mikture. The position of the butterfly valves obviously controls the clear space through the easing and thereby the velocity of the 'air passing through the casing, and, since the Q4 of the casing amount of fuel entering the casing is largely controlledby the difference inpressure or velocity of the air passing through the casing the position of the butterfly valves aecurately controls the amount of fuel used 1n the engine and thus, within certain limits, the power developed by the engine. Y Y

While in the foregoing specification I have shown and described a very desirable form of my invention, it is obvious that various parts may be considerably modified without departing from the spirit of my invention, I do not therefore wish to limit myself to the exact form or construction shown.

that I claim as new and desire to secure by Letters Patent is: ,Y
