UNITED STATES,

Application filed March 6, 1923. Serial No, 623,206.
T 0 all whom it may concern:
Be it knownthat I, CECIL EDGAR CAWLEY, a citizen. of the United States of America, residing at Parsons, in the county of Labette and State of Kansas,have invented certain new and useful Improvements in Air Controls for Carburetors, of which the following is a specification.
This invention relates to new and'useful improvements in air controls for carburetors and has reference to an automatically'oper- ,atingdevice positioned. in the air intake pipe for the carburetor at a point intermediate the carburetor and the stove associated with the exhaust manifold.
The primary object of the invention resides in the provision of an air control for carburetors wherein a tensioned valve plate when in its closed position is so constructed as to permit a limited quantity of air to flow thereby, and to be automatically opened to permit the passage of a greater quantity of air by suction created in the carburetor.
With the above and other objects in view as the nature of the invention is better understood, the same consists of the novel form, combination and arrangement of parts hereinatfer more fully described, shown in the accompanying drawing and claimed.
In the drawing, wherein like reference characters designate corresponding parts throughout the several views,
Figure 1 is a side elevational view of an air control for carburetors, a. portion of the air pipe associated with the carburetor being shown in section, and the carburetor and associated engine structure being illustrated by dotted lines,
Figure 2 is a side elevational view of the air control attached to a pipe section depending from the stove for the ain supplied to the carburetor,
Figure 3 is a sectional view taken on line IIL-III of Fig. 2 showing the spring for retaining the plate valve of the air control in its closed position, the plate valve being illustrated by dotted lines in an open position Figure 4 is a bottom plan view of the air control, showing the oval formation of the plate valve providing constant laterally positioned air passages through the control, and
Figure 5 is a sectional view taken on line VV of Fig. 4:.
It is the primary object of the present in- 1 I iscaezr vention to provide an air control for car-.
buretors associated with automobile engines for the purpose of reducing the consumption of'gas, suction created in the carburetor due to increased speed of the gas: engine providing for an increased supply of air'to the carburetor for proper mixture with the gasoline drawn therein, the air control be ing entirely automatic in its operation and positioned within the air supply pipe forthe carburetor at a point intermediate the 'c'arburetor and the stove associated with the exhaust manifold.
Referring more in detail to the accompanying drawing, there is illustrated by dotted lines, a carburetor 1 having an air supply pipe 2 connected thereto as shown in Fig. 1, a stove 8 arranged adjacent the exhaust manifold of the gas engine being arranged adjacent the upper open end of the air supply pipe 2, the stove carrying a depending relatively short pipe section 4: while the air control device is associated with'the upper end of the air supply pipe 2 and the pipe section 4. as shown in Fig. 1.
The air control embodies a cylindrical collar 5 having an enlarged coaxial flange 6 upon its upper end to receive the lower end of the stove pipe section 4, the collar 5 being positioned in the open upper end of the air pipe 2 and retained therein.
An automatically opening plate valve is associated with the lower open end of the collar 5, the plate valve opening outwardly of the coller and into the air pipe 2 by suction created in the carburetor 1, the plate valve 7 being hingedly connected at 8 to one side edge of the lower end of the collar 5, and being of oval formation as shown in Fig. 4 to provide constantly open air passage 9 through the carburetor. To retain the plate valve 7 in its normally closed position as shown by full lines in Fig 3, a coil spring 10 is anchored at one of its ends at 11 to a side wall of the collar adjacent the of gas, is delivered to the engine, the suction created in the carburetor automatically opens the plate valve 7 against the tension of the spring 10 for drawing in an increased supply of air, permitting the engine to operate with a leaner mixture of gas, reducing the gasoline consumption and automatically providing the proper mixture.
l/Vhile there is herein shown and described the preferred embodiment of the present invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.
What is claimed as new is In an air control for carburetors, the combination with the outer end of an air feed pipe for a carburetor and a hot air stove having a pipe extension, of means for controlling the flow of air through the hot air pipe interposed between the outer end of the hot air pipe and pipe extension carried by the stove and telescopically associated with each member, said aircontrolling means including a collar, an annular enlargement at one end thereof inclosing the pipe ex tension on the hot air stove with the collar extending into the outer end of the hot air pipe, an outwardly opening plate valve hinged at one end. at the inner end of the collar with the free swinging edge thereof overlying the inner edge of the collar to form an abutment for the plate valve during closing movement, the collar being cir oular and said Valve being oval to provide constant air passages at opposite sides of the valve plate and a coil spring anchored at one end to the outer end of the collar and having its other end secured to the plate valve adjacent the swinging edge for normally holding the valve in closed position engaging the inner end of the collar.
In testimony whereof I affix my signature.
CECIL EDGAR CAVVLEY.
