CARBURETOR.
Application filed March 1, 1920. Serial No. 362.591.
This invention relates to a carburetor for internal combustion engines, it being among the objects of this invention to produce a simple and reliable device for feeding fuel to engines which will make for considerable saving in fuel, and cause the engine to run more smoothly.
In carrying the objects of my invention into effect, I provide a source of fuel, both gaseous and liquid, and provide means whereby a charge of explosive .mixture is ready to be drawn into the engine at all times. I am thus enabled to start an engine in the coldest weather with ease- I have found that by utilizing a double source of fuel, gaseous and liquid, I obtain greater economy in operation. This invention constitutes an improvement on -the invention de scribed and claimed in my co-opending application, Serial No. 357,244, filed February 9, 1920, for internal combustion engines.
Referring to the accompanying drawings forming a part hereof, and inwhich similar reference characters denote similar parts.
The single figure represents a vertical sectionthrough an engine cylinder and fuel' supply tank, forming the subjectof this invention.
The engine cylinder 1 is supplied with a water jacket 2 and carries the ordinary piston 3 and piston rod 4, intake port 5 and exhaust port 6, as are well known. Although I have here shown a single cylinder engine of the two-cycle type it is to be understood that this invention is not limited to such an engine but it is applicable to the various engines of different types well known in the art.
The intake manifold 7 is connected tointake port 5 and carries a throttle valve 8 which may be actuated in any suitable manner. The fuel tank 10 has a dome or extension 11 formed thereon and communicating therewith; A pipe 12 leads from the top of dome 11 and is connected to manifold 7 by means of a mixing chamber 13 interposed in the path of the gaseous mixture from dome 11. I preferably include a check valve 14 in pipe 12 to prevent-back fire from the engine into dome 11 or tank 10.
An air intake opening 16 controlled by a spring pressed valve 17 is fixed to tank 10 and a pipe 18 leads the air to the bottom of the tank where a perforated distributor 19 uniformly distributes the air through the liquid in the tank agitating the same and causing gaseousmixture to collect into dome 11. A pipe 20 leads into tank 10 terminatliquid fuel have collected in dome 11 and pipe 12. When the engine is started the suction thereof will draw in the explosive mixture which is present even in the coldest weather and thus the engine may be readily started. WVhen the engine has attained approximately its normal speed liquid fuel will be drawn in through needle valve .24 in addition to the gaseous explosive mixture from dome 11, thus operating the engine on a mixture of gaseous and liquid fuel. I have found that by the use of such a double apparatus I obtain greater economy of fuel in operating the engine and also obtain smoother Workingthereof, less danger of back fire, and less liability of the engine missing.
Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent, is:
1. A charge-formingdevice comprising a fuel tank having a dome, a pipe leading from said dome to an internal combustion engine, means for admitting air beneath the level of the fuel in said tank, and a spray nozzle extending into said ipe from said tank the passages through said pipe and said spray nozzle being open at all times to the suction of the engine, substantially as set forth.
2. A charge-forming device comprising a said passages and said fuel tank having a dome, from said dome to an in engine, means for admitt level of the fuel in said t .5 extendinginto vsaid from said tank to sm check valves in the pas a pipe leading ernal combustion in air beneath the a a spray nozzle pipe, a passage leading spray nozzle, and sage and the pipe pipe being otherwise open to the suction of the engine, substan-- badly as set forth.
In witness whereof, I have hereunto set' my hand at Indianapolis, Indiana, this 25th day of February, A. 1)., nineteen hundred and twenty.
