Specification. a Letter: rm.

Patented June 19, 1908.

To all whom it may concern.-

Be it known that I, Jess Bmrs'rn neon: no Mannzreox, a citizen of the Be uhlic of France, and a resident of Paris, nee, have invented a new and use-- ful Carburetor for E losive-Engrnes, which is fully set forth in the ollowing specification.

invention relates to a carburetor m which the etomizi of the liquid carbureting medium is obtained by means of at ouracross the end of the V sheet-or jet iniector, thereby drawing the hydrocarbon to the ends of the ejector tubes or slots arranged iior the purpose and 1mmersed in the liquid, the air-current being produced by any suitable means, more particularly by means of the vacuum produced by the engine when working.

In order to render the description as clear as possible, several constructions of the carbureter accor to this invention are illustratgilby way 0 example, in the accompanyfi ig'ure 1 is an elevation, and Fig. 2 is a perspective view, of a carburetor in vertical section, certain parts being removed to show the construction of the sheet-jet. 3 to 6 show details of spring-valves admitting ear to the carburetor in question.

The carburetor, Fig. 1, is desi ed so that a multiplicity of ets are repl by a jet in the shape of a sheet, so as to render the atomizing continuous, the object of this being alwa s to have the same proportion of hydrocar on whatever he the opening of the passage admitting the explosive-gas mixture to the engine-cylinder. This is, as a rule, very difficult to attain with multi le jets. Secondly, the valve controlling t e sup 1y of air to be mixed with the atomized hyd ocerbon and which is liable to nick wear is replaced in this construction y a flat splral or conical or helical spring acting as a valve. Moreover, this construction 0 carburetor is combined with a pneumatic governor.

The arrangement of the jet in the shape of a sheet necessitates, chiefly, two longitudmel substantially parallel coves a 1:, Fl 2, and a flettene tube 1: o the some widt as the oves a b. This tube plan into the by arbon in the reservoir of the carburetor. Air enters freely throu 'h the groove 0 and causes the flow of the yokecarbon, wluch rises through the tube 0 to the orifice of the slot 6. On escaping from the slot 5 the hydrocarbon is literally pulverized by the an,

Referring to Figs. 1 and 2, n is an airrccei chamber provided with a valve i, throng which air is permitted to enter when the pressure within the chamber is reduced below that of the atmosphere. g is a carbureted air-delivery chamber which communicates with chamber a throu h an opening f and wln'ch is connected at 9 by a condu1t s, Fig. 1, with a suitable pressure-reducin device, such as an explosive-en ine. For t e purpose of regulating the size 0 the communicating opening f between the chamber g and a two sliding valves 9 and e are provided; The valve 9 is raised and lowered y any suitable means, such as a screw 38. Valve 0 is actuated by fluctuations of pressure in the suction-pipe sbetween the engine, for example, and the carburetor, and for this purpose valve 2 is connected by a lug 39 to a rod t with a piston g m cylinder oommunicatin at r with conduit 8. fi er the purpose 0 simultaneously controlling the olive of oil spray to the air passing thro opening f, slide-valve e is made I.- shape the horlzontal member having a slot which extends nearly across the width of the member and divides it into two portions e e", which latter rest over the grooves or pass es 0 and b. Depen from the bottom w l of chamber n is a ange 40, entering the groove between portions e e" and forming a closure for the chamber at this point. It will thus be seen that any movement of the piston Q will be transmitted through rod and thereby slide over the openingsf, b, and a to regulate the air entering groove a, the oil-spray passin out of b and the quantity of on passing t rough o ningf. A re uletmgregister g,oapa leo movmgverticall and the slide-door e, cooperating therewith, determine at the opening required for the suplgly of by rocarbon.

e valve 2', shown on the righthand side of the carburetor, Fig. 2, can be advantageously replaced either by a spiral sprin k of flat shape, Fig. 3, or by a conical spire springi Figs. 4 and 5, or by a helical spring 3', closev at one end by means of a disk or washer in, Fig. 6. The S)lll1 "5 in question can be rendered mljustailo 1y combining, in the manner illustrated in Figs. 3, 5, and 6, a spring 1 acting in opposition and compressed by means of a nut m. 'llncse springt to valve e and its horizontal members c e", i

valves wear almost iiide'linitely, they are perfectly silent, and their working is very elastic.

The earbureter havin T been assembled and the three supplies through a, ll, andfhaving been judiciously combined, the register 1 properly adjusted, as well as the tension of the spring-valve h, "i, or 7' arranged at n on the carbureter, no variation in the earbureting of the air can take place whatever he the speed of the engine.

The pneumatic governor consists of a eylindcr 7), Fig. 1, provided with a piston r and operatesthe slide r by theaetion of a vacuum. The cylinder 7) communicates directly at 1' with the suction-pipe s between the engine and the carburetor. 'lhe piston q is secured to the rod tot the slide 1, the other end of the rod a passing through a spring "o acting in opposition to the piston g. lhe tension of the said spring resting against the part a can be adjusted by means of a nut 1), screwed on the screw-threaded. end of the rod t. The face of the piston away from the engine is exposed to atmospheric pressure.

Every time that the vacuum produced by the suction of the engine is sulliciently strong to overcome the resistance of the spring a the piston q is drawn toward the lel't, Fig. l, carrying with it, consequently, the slide e. which closes at the same time the passageopenings for hydrocarbon and air. ll the spring 11 be adjusted for a speed of J: revolutions of the engine, each time that this numher is slightly exceeded or even attained the piston acting as a governor, causes the engine to slaeken down until the vacuum becomes normal. it is therefore possible, lilst, to produce variable quantities of carbureted air withoutpossibility of changes in the eharging owing to the mere fact that it is impossible to uncover a jet without simultaneously giving passage to such a uantity of air that its output can be proper y carbureted; secend, to vary the power of the engine and to maintain it working at any intermediate point between the maximum and the mini mum without fear of any trouble with the. carburetii'ig; third, to ellect a considerable economy in the consumption of hydrocarbon owing to the uniformity of the charging,

and, fourth, to efleet the carbureting so that the combustion of the mixture is perfect and there is an absence oF smell at the exhaust.

I. In a carbureter, the combination of a reservoir, for containing a carbureting liquid, an air-receiving chamber having an air-inlet, a valve normally closing said inlet, a carbureted air-delivery chamber communicating with said air-chamber, a spraying device delivering said liquid to the air-chamber, a valve simultaneously controlling said spray device and a passage between said two chambers, and a valve for independently controlling said passagev 2. In a carbureter, the combination of a reservoir for containing a carhureting liquid, an air-chamber having an air-inlet a valve normally closing said inlet, a earbureted airdelivery chamber communicating with said air-chamber, a spraying device, comprising a flattened tube having one end opening into the reservoir and the other provided with branching conduits, one communicating with the atmosphere and the other with the airchamber, and a valve simultaneously controlling the passage between said chambers and the openings of said slits.

3. In a earhureter, the combination. of a reservoir for containing a carbureting liquid, an air-chamber having an air-inlet, a valve normally closing said inlet, a earbureted airdelivery chamber communicating with said air-ehan'lber, a spraying device comprising a flattened tube having one end opening into the reservoir, and the other provided with branching conduits, one communieatin with the atmosphere and the other with the said air-chamber, and an Lshaped valve simultaneously controlling the passage between said chambers and the openings of said branching conduits.

in testimony whereof I have signed this specification in the presence of two subscribing witnesses.
