A50. HUGILL. MATIC AIR VALVE FOR GAS ENGINE MANLFOLDS.
AUTO
APPLICATION FILED JUNE 20. \918.
Patented May 13,1919.
ASHTON C. HUG-ILL, OF FORIDHAM, NEW YORK, ASSIGNOR, BY MESNE ASSIGNMENTS, TO ALLIANCE CO. IN 0., OF BOSTON, MASSACHUSETTS, A CORPORATION OF DELAWARE.
AUTOMATIC AIR-VALVE FOR GAS-ENGINE MANIFOLDS.
Specification of Letters Patent. Patented May 13, 1919.
Application filed June 20, 1918. Serial No. 240,911.
To all whom it may concern:
Be it known that I, ASHTON C. HUGILL,
a citizen of the United States, residing at Fordham, in the county of Bronx and State of New York, have invented a new and useful Improvement in Automatic Air-Valves for Gas-Engine Manifolds, of which the following is a specification.
The object of my invention is to provide a device which will admit air in limited quantities on the suction stroke of a gas engine and thereby cause the air and gas mixture to be so proportioned that there will be a minimum use of hydrocarbon vapor or gas to produce a given power. This device is preferably applied direct to the manifold of a gas engine but may be otherwise applied, if desired. This and other objects are accomplished by my invention, one embodiment of which is hereinafter more particularly set forth.
For a more specific description of my invention reference is to be had to the accompanying drawings, forming a part hereof, in which:
Figure 1 is a sectional view of my improved device.
. Fig. 2 is an elevation of the same.
Fig. 3 is a sectional View taken on the line 33 of Fig. 1, looking in the direction of the arrows.
Figs. 4 and 5 show a spring valve plug which closes the intake opening of the device.
Throughout the Various views of the drawings, similar reference characters, designate similar parts.
My improved automatic valve 1 is attached to any manifold, or other suitable part 2, and is composed of a hollow plug 3 which has a reduced lower end which is secured to the manifold 2 by screw threads or otherwise as desired, and placed therein is a regulating screw 4 by means of which the size of the opening through the plug 3 may be regulated. The top of the plug 3 is provided with screw threads to receive corresponding threads on a, cap 5 with a concave top which has a perforation 6 at its upper extremity. This perforation 6 is normally closed by a spring valve plug 7 which surmounts a coil spring 8 that rests on the top of the plug 3 and holds the spring valve plug 7 against the cap5 with a gentle pressure which will be readily overcome by suction through the bore of the plug 3.
The spring valve plug 7 may be made in any suitable manner provided it conforms to the cap 5 and it is preferably made with its upper portion formed so as to fit the concave surface of this cap 5 and it has grooves 10 at its edge so as to provide suitable passages for air to pass through and it is also provided with upwardly extending lugs 9 which extend far enough to engage the top of the plug 3 before the spring 8 is compressed to any injurious extent and so protect this spring from injury during the operation of the apparatus. It will be noted that the concavo-convex surfaces of the cap 5 and valve plug 7 engage to form a tight joint without blnding so that leakage is prevented and yet atmospheric air may easily enter through the vent 6 whenever there is a sufiicient vacuum in the cap 5.
In view of the foregoing, the action of my improved valve will be readily understood, assuming that there is a suction stroke of an engine to which this device is attached as above described, the suction will make a partial vacum in the cap 5 and thereby cause the valve plug 7 to be lowered by air pressure through the opening 6 and this will permit a ready flow of air about the cap 7 and through the bore in the plug 3 to the engine through the usual path. The amount of air that may pass is determined by the position of the screw 4. When suflicient air has entered, the spring 8 will act to close the vent and this cycle of operations is repeated as long as the device is in use. I have found that the addition of my improved device, without any other change whatsoever, will reduce gas consumption from 30 to 50%.
While I have shown one embodiment of my invention, it is obvious that it is not restricted thereto, but is broad enough to cover all structures that come within the scope of the annexed claim.
What I claim is:
In a device of the class described, a perforated plug adapted to be secured to a manifold or similar means and means in said plug for regulating the size of the perforation therein, a spring, a cap with a concave top mounted on said plug and vent open- I rest on said spring and to press against and the valve plug may move undeic atmospheric 7 I fit the interior of the cap, and lugs which pressure through the vent and permit alr to extend far enough from' the valve plug to pass through the device. 10
engage the plugand protect the spring, said In testimony whereof I have -hereunto 5 parts being so arranged and disposed that afiixed my signature.
the valve plug slides freely in the plug and r V Y normally closes, thevent therein, and that ASHTON C. HUGILL.
