Specification of Letters Patent.
Patented J an. 17, 1911.
Application filed November 4, 1909. Serial No. 526,205.
T 0 all whom it may concern:
Be it known that I, Lnwis P. l'lanmnnv, a citizen oi the United States, residing at (.lhicage, in the county ot Cook and State of Illinois, have invented a certain new and useful lu'iprovement in Carburetors, of which the following is a specification.
My invention relates to improvements in carburetors. and is illustrated in the accompanying drawing wherein the device is shown. in section.
The feed pipe A communicates by means of a valve )1 which is controlled by the bell crank A and lie-at A with a fuel chamber A which chamber surrounds the carbureter B, being held rigidly in engagement with it. at B and ll by the nut ll. The fixed air intakes ll counrumicate with the passage l3 and mixing chamber ll which in turn C0l'llli'itil'li.litt5 with the engine by a passage controlled by the butterfly valve B The passage 0 which may be closed by the needle valve D leads to the cylinder D The passage 1) leads through the wall of the cylinder D into the cup D The auxiliary air intake l) controlled by the valve E which held upon its seat by the spring E and rides upon the rod E which is screw threaded in the hub E" to adjust the tension of the spring E. The rod F is pivotally mounted upon the valve Ill and has screw threaded upon it the sleeve F which is in engagement with one end of the bell crank F The other end oi the hell crank is in engagement with the rod F which supports at one end the needle valve D, is surroumled by the spring F which is in engagement at; one end with the top of the cup D and at. the other with the collar F rigidly mounted upon the rod. The sleeve F which is slidably mounted inthe wall of the carbureter, may be rotated by means of the thumb piece G to vary its position with relation to the valve E. thus varying the tension upon the spring F. The bell crank G is pivotally mounted upon the wall of the carburetor, the arm G being held in engagement with the corrugations G on the piece G by the tension of the spring G the lever H and connecting rod H being adapted to control the butterfly valve B".
I have shown in the drawing an operative device but it will be evident that the arrangement shown could be greatly changed without departing from the spirit of my invention. I wish, therefore, that my drawingz be considered as diagrammatic.
The use and operation of my invention are as tollows:-The fuel fed to the Oil chamber and its level therein controlled in the usual manner. Air is drawn in through the usual air opening past any suitable injecting device and a combustible gas is .thereby formed. This as thus termed under ordinary circumstances passes through the carburetor into the engine. Under cer tain circumstances the supply of gas thus normally generated becomes insullicient, whereupon the suction from the engine increases and the auxiliary air intake is opened. This, while producing more gas, produces at the same time a weaker mixture. To provide against this weakness of the mixture the fuel valve is arranged to operate automatically responsive to said auxiliary air valve. Thus when the auxiliary air valve is opened an increase of supply of fuel is supplied to furnish a rich mixture. The mixture, of course, can be manually adjusted by any desirable means and when once so adjusted will always remain constant owing to said relation between the auxiliary intake and the fuel valve.
A carbureter comprising a mixing chamber, an air passage thereto, a fuel feed located within said air passage, a port in the wall of said carbureting chamber, an auxiliary air valve controlling said port, adjustable means for controlling the opening of said auxiliary valve and elastic means operating to force the fuel valve in an open position, a turn buckle connection from the auxiliary valve a bell crank lever in connection with said turnbuckle which in turn engages the fuel valve and resists the opening tendency.
