CARBURFTER.
Specification of Letters Patent. l Patented 001;, 22,1912
Application tiled September 21, 1911'. Serial No. 650,654.
To all lwhom it may concern:
Be it known that I, ALBERT R. LONG, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Carbureter, of which the following is a specification.
This invention relates to a carbureter for use vwith internal combustion engines, and one object of the invention is to maintain any given or desired proportion of air to fuel under automatic control of the suction of the engine.
Another' object of the invention is to provide for variation of the given proportion of air tooil under control of the operator.
A further object of the invention is to transform the fuel if liquid fuel is used, to gas with sufficient air to prevent condensation before it is delivered to the fresh col air being taken in by the engine.
Other objects of the invention will appear hereinafter.
The' accompanying drawings illustrate an' embodiment of t e invention, and referring thereto: Figure 1 1s a side elevation of the cai-buieter. Fig. 2 is a vertical section thereofV` by a throttle 4, said member 2 being pro- .vided with means such as flange 5, for' connection with the intake of an internal combustion engine. TheA casing 1 is formed with lateral air inlet ports or openings 7 and is closed at the bottom, the bottom member or portion 8 of the casing being formed with a central tubular portion 9 servingv as a guide for a stem or stud 10 of the air valve. Said air valve consistsof a cylindrical shell 12 mounted to slide within the cylindrical casingl, said shell being o en at the top and closed at the bottom, with the stem 10 extending downwardly from the closed bottom of the shell. Valve shell 12 is formed with side ports or openings 11, for coperating with the ports 7 in 'the asing. Valve shell`12 is rotatable as well as slidable in ca'sing 1 and is guided vertically by a-pin 12 on the valve engaging in a slot 13 in -a vertical ilange 13 depending from a ring 6 which is mounted to t-urn in an annular groove l in casing 1 and is provided with operating means 6. The stem 10 is hollow and serves as a means for introducing fuel into the carbureter, the lower end of said stem having perfo-rations 14 communicating with the interior chamber 15 in the stem and opening at t-he bottom of said stem. A tubular riser .lGvextends up from the bottom of member 12 and communicates at its lower end with the interior of the hollow stem, and at its upper end with the mixing chamber within .the casing 1.' From t-he bof-tom of the stem 10 a needle valve or regulating pin 1S extends downwardly into a bore or chamber 19 in a screw 2O which screws into a head 21 formed on the lower end of the tubular .member 9. A'tubular fuel supply connection 22 opens into said head and communicates through passages 23 in the screw 20 aforesaid. At the upper end of the head 21 there is provided a valve seat 241 cooper ating with the lower end or bottom of the valve stem 10 to'form a complete shut oli' for the fuel when the valve is down. The tubular member 9 is further provided with a lateral tubular extension 25 forming an air inlet communicating with a passage 26 'extending stem, suiilcient air to carry up into the valve, the oil or fuel 'furnished through the oil or fuel inlet. Said tubular member 25 communicates with any suitable heating means, for example, a pipe 27 extending alongside the exhaust pipe 29 of the engine, to receive heat from the exhaust and heat the air passing to the air inlet at 25. A deiieet-or 29 may be provided to increase the heat absorbing effect. A. spring 28 extends between the top or cap member of the casing l and the bottom of the valve shell 12. tending to hold the valve in closed position to cut olf bot-h air and oil supply, the valve closing by spring pressure independently of Aor in conjunction with the action of the gravity, according to the position of the carbureter.
The operation is as t'ollows: lorn1ally,vor when the engine at rest, the air valve 12 is closed, said valve being held down by spring 28 so as to bring the ports l1 out of register with the ports 'i'. ln this position of the valve the bottom of the stem l() f the valve rests on the valve seat 24; so that communication with the oil supply .is cour around the lower end of the valvev
