UNITED STATES PATENT OFFICE.
EVEN JOHANNESSEN' VERAASEN, OF GJOVIK, NORWAY.
DEVICE FOR DRIVING MTORS WITH A HEAVY AND A LIGHT FUEL.
Application filed September 30, 1922. Serial N'o. 591,!545.
To all whom z'z may concem:
Be it known that I, EVEN JoHANNEssEN OVERAASEN, a subject of the King of Norway, residing at Gjovik, Norway, have in- Vented' certain new and useful Improvements in Devices for Driving Motors with a Heavy and a Light Fuel; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled `in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.
The present invention has for its object a device for driving internal combustion engines alternately with a light and a heavy fuel such as gasolene or kerosene, the device being adapted for automatically changing from one fuel to another in accordance with the Varying load on the engine.
For stationary motors the change from one fuel to another may be eaused by means of a piston which is influenced by the variations in motor suction or exhaust pressure, which take place when the load on the engine is varied.
In motors 'for automobiles, motor boats and the like the ,change from one fuel to another may preferably take place by means of a mechanical connection between the throttle 'valve and the' change valve.
In both cases the main feature of the present invention consists therein that the change from one fuel to another takes place instantaneously so that no gradual decrease of the supply of one fuel or gradual increase in the supply. of another fuel takes place, but on the contrary the supply of one fuel is completely cut ofi in the same moment as the supply of the other fuel is opened. v
In order to attain this object the supply of the two fuels are provided with interconnected valves which are so connected with an adjusting mechanism by means of a spring, weight or the like, that they can only take up two difierent positions, each position correspo-nding to the complete cutting off of one supply pipe and the complete opening of the other.
On the drawing:
Fgs. 1 and 2 represent sectional view and plan view of the fuel supply device for a statonary motor.
Figs. 3 and 4 are section and plan of a fuel supply device for an automobile or boat motor.
O n Fig; 1 the suction conduit 1 of the motor 1s connected by means of channel'2 with cylnder 3 in which is slidably mounted piston 4. To piston 4 is fastened piston ro d 5 connected with arm 6, which transmts its movements through shafts 14 to a second arm 7. The free end of said arm 7 s connected with a helical spring 8, the opposite ends ofwhich is fast-,ened to arm 9. Arm 9 acts directly on the two needle valves 10, 11, which shut or open the supply ppes for kerosene and gasolene.
From the exhaust pipe of the motor there leads a pipe' 12, which is connected with cylinder 3 under piston 4 through needle' valve 13. When the motor changes from light to heavy load a suction will be created in cylinder 3 over piston 4, and a pressure from the exhaust pipe will be created below piston 4. Piston 4 will therefore be lifted and the movement will be transmitted through arms 6 to arm 7.
The direction of the pull exerted by the sprin will be changed by the movement of arm When arm 7 is moved up wards the direction of pull of the spring after having passed through motor shaft 14 :will finally form a sufficiently big angle with the center line of arm 9 that the end of the arm to which spring 8 'is fasten'd will be pulled up and open valve 10, while at the same time the opposite end of the arm will close valve 11, thus opening the kerosene suppl and closing the gasolene supply simu taneously.
When the load on the motor is decreased piston 4 will move downwards and the direction of pull of spring 8 will cause arm 9 to tilt back into' its orignal position closing the kerosene su ply and simultaneously opening the supp y of gasolene.
Needlevalve 15 is mounted for controlling the downward movement of piston 4, needle valve 16 controls the supply of gasolene and. kerosene.
According to Figs. 3 and 4 the movement of valves 10, 11 takes place mechanically by direct connection with the mechanism for. throttle valve 17.
Arm 7 to which one end of springs 8 are fastened is mounted on a pivoted shaft 18 which carries an arm 19 connected by means of rod 20 with the arm 21 serving to move throttle valve 17. Arm' 21 is controlled from the footspeeder or the like by means of rod 22.
The supply of the heavy fuel (kerosene) takes place from a particular float chamberr 23 through needle valve 1'1 to the suction tube 1, while the light fuel (gasolene) is supplied from another float chamber 24:. The supply openings of the several pipes are controlled in the ordinary manner by means of adjustable needle valve 16.
The suction pipe is provided as usual with a non-return valve 25, and further there is provided an adjustable stopper 26, which may be adjusted by means of a bell crank lever 27 so as to keep needle valve, 11 closed and needle valve 10 open irrespective of the movement of arm 7. This is in case it should be Wanted to completely shut off the supply of heavy fue] irrespective of the load on the engine.
Claims. p
In a fuel supply device for internal combustion engines two supply pipes for supplying two different kinds of fuel, a controlling valve for each supply pipe, a pivoted two-armed lever interconnecting said controlling valves, a spring connected at one end with one arm of said lever, and means for moving the opposite end of the spring perpendicularly on the center-line of said arm, said means being operated in accordance with the load on the motor so as to automatically change from a light to a heavy fu'el, When the load on the engine is increased and vice versa.
In testimony that I claim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses.
