CARBURETER.
Specification of Letters Patent.
Patented July2'7,1915.
Application filed June 24, 1912. Serial No. 705,634.
To all whom it may concern:
Be it known that I, JEROME E. RUssnLL, a citizen of the United States, residing at Rodd, in the county of Floyd and State of Iowa, have invented a new and useful Carbureter, of which the following is a specification.
The object of my invention is toprovide a carbureter of extremely simple, durable and inexpensive construction, provided with means whereby the liquid fuel is fed rapidly into the carburetor and into the mixing chamber, for the purpose of thoroughly mixing the gasolene vapor and the air.
A further object is to provide in such a carburetor, means for mixing a certain amount of air with the vapor and additional means for manually and automatically regulating and controlling the admission of more air to the mixing chamber.
My invention consists in certain details, in the construction, arrangement and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claim, and illustrated in the accompanying drawings, in which Figure 1 shows a central, vertical, section through a carbureter embodying my invention. Fig. 2 shows a top or plan view of my improved carbureter.
In the accompanying drawings, I have used the reference numeral 10 to indicate a float chamber. At one side of the chamber 10 is a chamber 11 into which gasolene is admitted through the tube 12. The admission of gasolene is controlled by a needle valve 13 and an ordinary float 14:- Connected with the chamber 10 is a valve 15 for emptying the float chamber. In one side of the chamber 10 is a horizontal air passage 16 which extends to a position approximately in the center of'the float chamber and is then provided with a vertical extension forming a mixture passage 17 of smaller diameter than the air passage 16. Below the mixture passage 17 is formed an upwardly anddownwardly extending portion 18 in which is an opening which forms a valve seat for a needle valve 19 which may be controlled by any ordinary means not shown. It is desirable'to have the passage where the gasolene is admitted, of the same size as the air passage 16. The part 18 somewhat fills up the vapor passage and the vapor passage is therefore enlarged at 16 On account of the contraction of the mixture passage 17, the rapidity of the flow of air and vapor therethrough is increased.
Above the mixture passage 17 is a larger dis charge tube 20, the lower end of which serves also as a mixing chamber. In the discharge tube 20 is an ordinary throttle valve 21. Communicating with the tube 20 is a.
horizontal air inlet tube 22 in which is a throttle valve 28 controlled by a manually operated lever 24:. In the end of the tube 22 is a screwthreaded plug 25 provided with a central opening 26.
I provide means for automatically admitting air to the passage-way 22 when the suction from the engine becomes great, as follows: Extending through the opening 26 is a valve stem 27, on the inner end of which, within the tube 22, is a valve 28. The outer end of the stem 27 is screwthreaded and on. the screwthreaded end is a nut 29. Between the nut 29 and the nut 25, is a coil spring 30 which is of larger diameter at its end adjacent to the nut 25 than the opening 26. The coil spring 30 normally holds the valve 28 seated, but when the suction from the engine becomes sufficiently great, the spring 30 is contracted and the valve 28 is unseated, thereby permitting air to enter the air inlet passage 22. The tension of the spring 30 may be regulated by means of the nut 29.
In the practical operation of my improved float, gasolene is admitted to the carburetor chamber through the tube 12, the inflow of gasolene being controlled by the float 14; and the needle valve 18. When the vapor and air passes into the mixing chamber, more air may be admitted as required. As the engine increases in speed, more air is necessary and the valve 28 is automatically opened by the suction of the engine.
By the construction just described, a satisfactory mixture is obtained at all times. WVhere a very rich mixture is desired, the valve 23 may be manually operated to limit the amount of air admitted to the mixture.
The advantages of my improved carbureter are seen from the foregoing description. Some of them are the extreme simplicity of its construction, and the construction of the vapor passage, whereby the rapidity of movement of the vapor and air is increased, thereby giving a more thorough mixture of fuel and air.
I claim as my invention:
In a device of the class described, a float 1 means for controlling the admission of gasosage, a valve in said horizontal air passage,
means for admitting gasolene to said casing,
lene, a horizontal air passage entering said chamber at a point beneath the top thereof,
'- and'constructed with a vertical upward mixture passage slightly contracted in size, and having its upperend in communication with the lower end of'said vertical air passage, a
engine.
