. a citizen of the United States, residing 'Valves for Carbure-ters;
AUTOMATIC AIR-VALVE FOR CARBURETERS.
Application filed April 13, 1920. Serial No. 373,511.
To aZZwwm t may cof/wem. v
Be it known that l, CLARENGI; E. CsBORNE, at Portland, in the county ofMultnomah and State of Oregon, have invented certain new and useful Improvements in Automatic Airand l do hereby declare the following to be a. full, clear, and
,exact description of the invention, such as will enable others skilled in the lart to which it appertains to make and use the same.
This invention relates to an automatic air valve for anarbureter and the principal object is to provide means for controlling the air supply to the carbureter in accordance with requirements of the engine.
A further object is to provide means for reducing the consumption of the fuel to a minimum.
A still further object is to provide a valve and a casing therefor which may be applied to the air intake of the carbure'ter, and which shall admit a quantity of air suilicient to permit of securing the best results with a given amount of fuel the degree of opening of the valve depending upon the degree of suction resulting from the operation of the engine.
A still further object is to provide a valve and acasing therefor which can be manufactured and sold as a separate attachment, complete in itself, and which can be applied in the position indicated without the necessity of employing expert assistance, and without the use of particular tools or of attaching devices.
With the foregoing and other objects in view, the invention consists in the novel construction, combination, and arrangement of elements hereinafter ,described and claimed.
linV the accompanying drawings the figure is a view in side elevation and section, showing the device as applied to the carbureter, at the intake side thereof, a portion of the engine and the intake manifold being illustrated.
it is well understood that an internal combustion engine gives the best results from a given amount of fuel when the proportion of air admitted can be accurately controlled, and especially when this control can be effected automatically. ln the present device the air intake of the carbureter is designated 10, the carbureter is shown at 12, and the intake manifold for the engine is desigmated le.
Specification of Letters Patent.
Patentedlutay 24., .1@@10 rlihe attachment" claimed herein may be manufactured as'an independent article and readily applied by anyone. lt consists of a casing 15 providing a valve seat 16 for a ball valve 17. This valve is normally yretained in a closed position by-means of a spring 18 extending centrally and longitudinally of the valve casing and connected with a transverse element 19. This element la st 'named mayconveniently be made by slitting the end of the casingcircumferentially, as shown at 20, and forcing inwardly the strip o f metal thus separated, the ends of the 'strip' of course maintaining their connection with the walls of the casing.
As the supply of fuel increases with the speed of the engine, so also the supply of air increases, the greater suction causing the valve 17 to open farther, with the result indicated. lt is not only possible to save a considerable percentage of the fuel, but the deposit of carbon in thecylindersis also greatly reduced. y
hat is claimed is An attachment for carbureters comprising a. tubular valve casing, cylindrical in configuration, a valve seat connected with the walls of the casing, a ball valve coperating with the seat, a springconnected with the valve, one end of the casing being slit circumferentially and the strip formed thereby bein "deected inwardly to form a transverse e ement extending across the valve casing, said spring being connected with the transverse element.
2. An attachment for carbureters comprising a valve casing having one end turned outwardly and its opposite end curved inwardly and apertured tor form a valve seat, a ball valve cooperating with said seat, a
spring connected with said valve, the first mentioned end of the casing being split circumferentially and the strip formed thereby being deected inwardly to the longitudinal center of said casing to form a transverse element extending partially across the valve casing, said spring being connected with said transverse element to resiliently retain said valve in engagement with
