Applicationlled February 5, 1925. Serial No. 7,071.
The invention generally relates to c arburctors'and has for-its obiect to provlde a simple improvement therein effective in ob- Y viating induction into the engine to which the carburetor is attached of gasoline in liquid state, w'hlch undesirable condition 1s now commonly experienced upon exercise of air lll gate choke action in flooding the combustion chambers to aid starting.
The above stated object is efficiently accomplished by the structural details of improvement first fully described in the following specification, particularly pointed outin the claims appended thereto and illustrated in the accompanyingdrawing, in vvhich:
Figure 1 is a diagrammatic side elevation illustrating the application of the invention.
Figure 2 is an enlarged longitudinal section taken through the air passage intoy the carburetor. l.
Figure 3is a cross section taken on the line 3-3 of Figure 2.
Figure 4 is a vlew similar to Figure 2 and illustrates a modification of the invention.
Iny the drawing, in which like numerals of reference indicate like part-s in all of the iigures, 1 represents the carburetor which includes the usual gas passage 2, and air in duction passage 3. The invention is adaptable to use on any of the Well-known types of carburetors as they all include the passages 2 and 3 referred to, the said passages being gate controlled in 'the usual manner.
The air passage control gate is indicated by the numeral 4 and isin vthe nature of the usual butterfly valve horizontallyl pivoted across the passage on the pivot pin 5 upon the extended end`of which is mounted the operating crank arm 6 movable, from a remote but convenient point, through the me dil/1m ofthe connection 7 which may bea rod, chain, or cord, as desired. l
A stop lug 8 is provided and a spring 9, coiled about the pin and connected with the crank 6 and lug 8, serves toho1d the gate 4 to its -horizontal or' full-open position with the said crank in engagement with the said lug. -f.
The gasolinel supply tank is indicated at 10. l
I `have found that much of the difficulty of starting an engine is due to lack of vapor. The use of the choke, i. e., the manipulation of the air gate 4 in the air induction passage 3 to close offV air induction, often causes the taking into the sengine a suction of all-gasoline. This causes the taking in of gasoline in liquid form, the presence of which in the combust-ion chamber renders effective explosion very diflicult, and alsothe passage of such liquid down past the pistons into the oil supply.
.l It is a known fact that the gasoline supply tank itself contains volatile vapor which drawn indirectly would, upon induction into 'the combustion chambers, render possible an ator, Wishing to start his engine, pulls on the connection 7, thus closing the gate 4 and at E v once cutting off air induction `and opening communication with the volatile vapor con- -duit 13 serving to induce passage of pure vapor into the combustion chambers of the engine. vWhen this has been accomplished" the operator slowly releases the connection 7 and the spring 9 opens the gate 4. thereby I. simultaneously opening the air passage 3 and l closing off vapor communication `by closing over the end of the extension 12.
Should it be deemed necessary, in order tov secure the maximum air induction, to remove the obstruction formed by the half-way extension 12, that extension may be reduced as indicated at 14 and a plunger plate 15, stilt connected to move with the gate 4, provided for the purposes explained.
The functioning of the invention for the purposes stated is effective and certain and does not alter in any way the usual practices of starting the engine other than in effecting the improvements stated.
What I claim is:
1. The combination with a carburetor having the usual air intake passage and the usual butterfly choke valve for controlling that passage and spring-held to the normal fully open position, of a tube having one end in \communication with an explosive vapor supply and-the other end thereof projected into the air intake passage of the carburetor just inwardly of the center of said choke valve and approximately half way across the intake passage whereby the said pipe endV will be closed off by said valve when said valve is at its normal open position and opened to admit explosive vapor into the air intake passage when said valve is closed to choke-off air induction.-
2. The combination with a carburetorhaving the usual intake passage and the usual butterfly choke valve for controlling that passage with means for normally holding the butterfly valve to the fully lopen position, of a tube having one end in communication with an explosive vapor supply and having the other end thereof projected into the air intake passage of the carburetor` in proximity to said butterfly valve, said butterfly valve and said tube having associated parts so arranged that 'said pipe end within the passage will be closed off when said valve is at its normal position and will be opened by the movement of said valve away from its normal position to admit explosive vapor into the air intake passage at a place between the butterfly valve and the mixing chamber of the carburetor.
