CARBURETER.

To all whom it may concern:

Be it known that we, CHARLES F. MEYER and ADoLPrI J. MEYER, residing, respectively, at the city of New York, borough of Manhattan, in the county and State of New York, and at test Hoboken, Hudson county, in the State of New Jersey, have in vented certain new and useful Improvements in Carbureters, of which the following is a full, clear, and exact specification.

Our invention relates to improvements in means for controlling the supply of explosive mixture for use as a motive power in explosion engines, and the same has for its object, more particularly, to provide a simple, efficient and reliable apparatus which may be readily connected intermediate the source of fuel supply and the intake side of the engine.

Further, said invention has for its object to provide a carbureter whereof the float casing is so constructed that the same may be readily reversed and attached to the vaporizing portion of the carbureter in order to adapt the carbureter to the varying conditions or arrangements of parts intermediate the source of gasolene supply and the engine.

Further, said invention has for its object to provide a carbureter which will automatically adjust itself to the varying opcrating conditions of the motor, and at all times provide a duly proportioned explosive mixture.

Further, said invention has for its object to provide a carbureter in which the gasolene is caused to issue in a number of fine jets or sprays in the presence of a plurality of air jets, which are conducted into the vaporizing chamber to either side of, and at an angle to said gasolene jets, whereby said gasolene jets are swirled around and broken up in order to completely atomize the same.

Further, said invention has for its object to provide a carbureter in which the gasolene which is not vaporized in course of operation of the apparatus will be con ducted to a suitable receptacle or pan, adjacent to the gasolene nozzles, and commingled with the incoming air.

To the attainment of the aforesaid objects and ends, our invention consists in the novel details of construction, and in the combination, connection and arrangement Specification of Letters Patent.

of parts hereinafter more fully described and then pointed out in the claims.

In the accompanying drawings forming a part of this specification wherein like numerals of reference indicate like parts, Figure 1 is a central vertical section taken substantially on the line 11 of Fig. 2, showing one form of carbureter constructed ac cording to and embodying our said invention; Fig. 2 is a bottom view thereof; Fig. 3 is a transverse section taken on the line 33 of Fig. 1; Fig. 4 is a detail plan view showing the arrangement of the gasolene nozzles and air inlets; Fig. 5 is a detailed sectional view taken on the line 5 5 of Fig. 4; Fig. 6 is an enlarged detail trans verse section taken essentially on the line 6-6 of Fig. 4; and Fig. 7 is an enlarged detail. back view showing one of the auxiliary air valves.

In said drawings, 10 designates the carbureter as a whole, comprising a tubular casing portion 11 having one end constructed in the form of an elbow 12, surrounded by a water jacket 13. The bottom of said casing terminates in a V-shaped lower portion 14 which communicates at its upper end with the tubular portion 12, and is provided at its lower end with flanges 15, 15.

The opposite inclined sides of the lower portion 14 are cut away to accommodate cover plates 16, 16 which are secured thereto by means of screws 17, 17. Each of said cover plates is provided with a central opening 18, and upon the inner side of each of said plates is secured a hinged cover or valve 19 mounted upon a pin 20 supported in a bearing 21.

22, 22 denote hoods arranged upon the outer surfaces of these cover plates 16, 16, and partially surrounding the upper portions of said openings 18, 18. Each of said cover plates 16 is provided with a bearing 23 which is made integral at its upper end with the hood 22, and 24 denotes an adjusting screw extending through said hood and provided at its inner end with a head .25 adapted to engage the free end of the hinged cover or valve 19. A head 26 is provided at the outer end of said adjusting screw 24 for actuating the same.

The lower end of each depending bearing 23 is bifurcated, and adapted to receive an adjusting nut- 27 in threaded engagement with a screw 28 which is freely supported in the bifurcated lower ends of the bearing 23, and 2t) denotes a coil spring having its outer end secured to the inner end of the adjusting screw 28, and its inner end socured to the outer side of the cover or valve 19.

The horizontal portion of the tubular casing 10 is provided at its outer end with screw threads and adapted to receive a cap 30 having a cent 'al opening therein and within said horizontal portion is disp sed a hollow cylindrical piston or throttle *alve having a rod 32 secured at one end thereto, and its other end extending loosely through said screw cap 30 and adapted to be connected at its outer end to any usual or convenient means for operating said throttle valve 81.

denotes an adjusting nut arranged upon said rod whereby to limit the movement of said throttle valve 31, and 3t denotes a coil spring disposed about the rod 3:2, having one end bearing against the inner end of the throttle valve 31 and its outer end contacting with the inner side of the cap 30.

The tubular portion 12 is provided with an opening connnunicating with the interior of the V-shaped lower portion 1st, and at the junctitn'i ot the horizontal portion with the vertical portion of said tubular -asing 11 is provided a ii-shaped recess or notch 36 for permitting the passage of a small quantity of explosive mixture to the engine when the vehicle is at rest.

37 denotes a float casing having an inlet 38 controlled by a valve 39 and float lO, and ll denotes a tubular section connected to, and communicating with said float chamber 30 adjacent to the base tl'lCl'GOIf. Said tubular section ll is provided adjacent to its outer end with a base 42 having flanges 43, registering with the flanges l5, 15 of the tubular casing 11 to permit of said float casing 37 being secured by bolts 4 a l to said tubular casing as shown at Figs. 1, 2 and 3, or in a reversed position wnen the conditions of application make that desirable.

denotes a longitudinal recessed portion arrai'lged in the base intermediate the flanges 43, d3 forming a shallow receptacle or pan in which are arranged a series of gasolene nozzles ell it-t3 communicating with tne tubular section ll, and l7, 4;? denote two series of inclined air ports arranged in the base t2 the tubular section ll, and wardly a at either side of extending inan angle toward the gasolene nozzles l6, at; arr: need. in said recessed portion ilo of the base 42.

The air inlet ports ll", 4:7 are staggered relative to the gasolene nozzles 4-6, 46 in order that the incoming of air will be conducted partly across the path of said nozzles and strike or impinge upon the gasolene jets, in opposite directions, two sides thereof as the same issue L said nozzles, and thereby cause the same to be swirled or broken up, and intimately mixed with the incoming air.

41:8 denotes a needle valve extending into the tubular section l1, the stem ot which is adapted to extend outwardly through the bonnet oi the motor, and is provided at: its outer end with an ope 'ating handle whereby the supply of gasolene to the carbureter may be controlled.

The opc'ation ot' the (airlmretcr is as tollows: The needle valve is first opened to the required extent: in order to permit of the gasolene passing from the tloat casing 31" into the tubular section ell, and to the gas lene nozzles 47, lulereupon, and as soon as the valve stem is drawn outwardly in the direction of the arrow (4 l) the action of the engine will cause a quantity of gasolene, together wi h a duly proportioned quantity ct air, to be drawn through the opening 35, and into the norm n 12 of the upon carbm'eter and thence pass to the intake port of the engine. As the suction produced by the ope *ation of the engine is maintained the jets of gasolene issuing from the inlets lit, a? wil be met by a plur: lity of jets oi air which will strike each of said at an angle upon two side, and serve to swirl the same around, and break said jets of QtlSOlGllQ up, and in atomizing intimately iiiix .fiaid atomized sprays of gasolene with the inrushing air. The quantity of a'r admitted into the carbureter a ove the gasolene nozzles lf, 4:? may be controlled by the opening of the valves or covers 19, 19 which are aranged at an angle to the vertical axis of the casing in the inclined or \fishaped base of the vaporizing chamber. The amount of opening of said valves or covers 19, 19 may be positively controlled by the heads on the adjusting screws 2 1', 2h and the ten sion of the springs 29, 29, which hold the valves or covers 19,, 19 against the inner sides of the cover plates 16, 16 may be adjusted or aried by means of the adjusting nuts 2?, 2? working on the screws 28, 28. its the throttle 'alve is permitted to move inwardly again under the influence oi the coil spring 34: the supply of explosive mixture will be diminished, but in being so diminished will nevertheless be duly proportioned so far as the mixture of air ant gas is concerned to form a proper explosive charge, and when the throttle valve 31 has "cached the inner limit of its morenienh a small percentage of explosive mixture will. still be admitted to the intake side of the motor through the ll-shaped recess 36 arranged at the junction of the horizontal and vertical portion oil the raising 11, which will he sutlicient to maintain the engine in operation when the vehicle is at rest.

It will be noted that by means of our appa ratus the supply of explosive mixture Will be automatically regulated to meet the varying conditions of the motor; that by making the vaporizing portion of the apparatus reversible, the carbureter may be readily adapted to varying conditions or arrangements of the engine and its connected parts, and that by having the stem of the valve controlling the supply of gasolene extending through the bonnet of the motor, the same may be readily and conveniently adjusted to simultaneously control the supply of gasolene to all of the several nozzles 46, 46.
