CARBURETER. APPucA'TIoN man Nov. 5. |914.

Specification of Letters Patent. i i Patented 'Jani 4, 1916.
Application :tiled November 5, 1914. Serial No. 870,348. i
, To all whom it may concern:
Be it known that I, CHESTER F. JOHNSON,
a citizen of the United States, anda res`il dent of Detroit, vin the county of Wayne and State of `Michigan, have invented a new and Improved Carbureter, of which the following is a specification.
This inventionrelates to carbureters, and
l some of its objects are to provide means lvvlfiereby a rich mixture may be supplied 'when starting and when it is desired to Vaccelerate the engine temporarily for any f purpose, and whereby the richness of the `fuel mixture is reduced, when throttliiig down from high speed, to that corresponding to economical running.
This invention consists in the details of construction shown, described and particu` larly pointed out inthe claims.
the invention. l
In Vthe 'embodiment of my ,invention `sho'wmthe intake portion 82 4of the carbureter body 1 `has an air intake opening 83 in itsupper side, and hasfclamped thereto by, means of screwJbolts '(not shown) the oa't chamber top 84, and clamped between the top 84 and the body is a diaphragm 85 in which -a strangle tube 86 is mounted. The iloat chamber 87 is clamped to the top 84 by a hand screw 36, threaded into the lower end of a pipe 25, the upper end of v which passes through a threaded opening in the cover 84 and is Aextended to form a;
Apiston is guided by a pistonfrod 91 that passes through alined openings in the cover 4of the chamber 89, the lower Wall of the intake 8.2 and a spider 92 that extends across the opening 83, and is depressed by the pressure of' air onthe valve 93 (integral with or rigidly secured to the piston-rod 91) that is normally held in contactv with the seatv9`4-- by the buoyancy of the oat. In certain instances a compression spring 95 may be inserted between the valve and the lower Wall of the intake.
The primary air is admitted to the space between the diaphragm 85 and the cover 84 through a series of openings 27 but one of which is shown.
lIt will be understood that when an increased engine suction is communicated to 'the interior of the carbureter at any time seat, thus retarding the flow of air, which causes ,the mixture to be still further temporarilyl enriched. The float plunger or.
l lpiston also tends to reduce the flutter of the The accompanying drawing is a verticalsectioii through aV preferred embodiment of each instanceI in the neck of thecarbureter,
it is obvious that it may be located elsewhere; for example, in the manifoldof the engine.
1It is also lclear that many other changes may be made in the details of construction without departing from the spirit of my invention. I do not, therefore, Wish to be limited otherwise than as indicated by the subjoined claims.
1. A -carbureter comprising in combination: a mixing chamber, a fuel passage for discharging fuel into the mixing chamber, a fuel reservoir, means for maintaining a predetermined level of fuel in the reservoir, a yfloat arranged to rest on the liquid in the reservoir and to be projected thereinto, a 'throttle valve, an air inlet valve, means connecting the air inlet valve and the float so that movement of one iscommunicated to the other, the arrangement being such that when the throttle valve is being opened and the engine-is running, the air valve is opened and the float projected into thdy reservoir to v`cause the fuel mixture 'delivered to the carbureter to be temporarily enriched.
2. A carbureter comprising in combination, a mixing chamber, a fuel passage for discharging fuel into the mixing chamber, a,
ing .e predetermined level Ot fuel in theres*- ervoir, a ioat arranged to rest on the liquid I `beingsuch that when the ,throttle valve eis being opened 4and the engine is running, the
air valve Visopened andthe Hoat'projected' into the reservoir to cause the fuelmixture delivered to the carbureter to be temporarily enriched.
3. A ca'rbureter comprising in combination, a mixing chamber, a fuel passage for discharging fuel into the mixing chamber, a fuel reservoir, means for maintaining apredetermined level of :fuel in the reservoir, a float arranged to rest on the liquid in the reservoir and to be projected thereinto," a throttle valve, an air inlet valve, 'al seat for the air inlet valve, a spring tending to hold the valve on its seat, means connectingthe air inlet valve and the float so thatfmovement of one is communicated to the other,
the arrangement being such that when the throttle valve is being opened and the engine is running, the air valve is opened and the oat projected into the reservoir to cause Lieeeee the fuel mixture delivered to the carbureter to be temporarily enriched.
v4f. A caroureter comprising in combination, a mixing chamber, a fuel passage for discharging fuel into the mixing chamber,
a fuel reservoir comprising a main chamber and an auxiliary chamber 1n free communication with, each other, meansvfor maintaining a predetermined level of' fuel in the reservoir, a tiost arranged to rest on the liquid in the/auxiliary chamber and to be projected thereinto, a throttle valve, an air inlet valve, a seat for the air inlet valve, a spring tending to hold the valve on its seat, means connecting the airinlet valve and the float so that movement of one is communicated to the other, the arrangement being such that when the throttle valve is being opened and the engine i/sjrunning, the air valve is opened and the float projected into the reservoir1 to lcause the fuelmixture delivered to the carbu'reterzto be temporarily enriched.
ln testimony whereof l have signed this specification in the presence of tvvo subscribing Witnesses. CHESTER F. JOHNSON. Witnesses: L..M. SPENCER, HUGO VJ. KREINBRING.
