.. l. HURST GOVERNOR Filed July 8, i920 Patented Aug. 26, 1924.
PATENT- OFFICE.
JAMIES BURST, OF SAN FRANCISCO, CALIFORNIA.
GOVERNOR.
Application filed July 8,
To all whom it may concern:
Be it known that 1, JAMES HURST, a citi- -zen of the United States, residing at San F rancisco, in the county of San Francisco and State of California, have invented a new and useful Governor, of which the following is a" specification.
This invention is a device for automatically regulating the speed of an engine of the internal combustion type.
One of the objects of the invention is to provide a governor, the operation of which is controlled solely by variations in the velocity of the inflowing explosive mixture. A further object is to provide a governor of the type mentioned in which the control 'member is in the form of a pivotally mounted butterfly valve, having its lower portion normally maintained at such an angle that the traveling mixture will impinge thereagainst, whereby the valve will start to close when the speed of the mixture is too great, and will thereby cut down the motor speed by obstructing the flow of the mixture. A further object is to provide means whereby the incident angle of the valve may be varied. A further object is to provide means for normally maintaining the valve at the angle to which it is adjusted.
The invention will be hereinafter fully set forth and particularly pointed out in the claims.
In the accompanying drawing Figure 1 is a side elevation illustrating a governor constructed in accordance with the invention. Figure 2 is a similar view with the cover for the control parts removed. Figure 3 is a top plan view and Figure 4. is a longitudinal sectional view.
Referring to the drawing, 10 designates a casing provided with a central bore or chamber, and with flanges 11 and 12, by means of which it may be connected to the manifold of an internal combustion engine. Said casing is preferably piovidedwith a flattened face 13, as shown.
Extending transversely through the casing is a rock shaft 14, having one end projecting through the flattened portion 13. Secured to the shaft 14, in. any suitablemannor, is a butterfly valve 15 of well-known t e. Mounted on the projecting end of the s aftl l, is a regulating arm 16, normally held against movement by a set screw. The
1920. Serial No. 394,852.
lower end of the arm 16 is engaged by a spring 17, interposed between the arm and an adjustable abutment screw 18, mounted in a lug 19, projecting from the face of the casing. Spring 1? acts to hold the arm 16 against an adjustable stop 20, illustrated as consisting of a screw mounted in a lug 21, projecting from the face of the casing; A second stop screw 22 is adjustably mounted in the lug 19, the same being positioned to limit movement of the arm 16 away from the stop 20.
The arm 16, spring 17, adjustable abutment 18, and the stops 20 and 22 are preferably enclosed by a cover 23, which is secured in place by means of screws 24, the heads of which are provided with transverse bores, through which is extended a wire 25,
the ends of which are connected by a seal 26.
In practice the abutment 18 is adjusted to produce sufficient tension upon the spring 17 to normally hold the arm 16 against the stop 20. Said stop 20, is adjusted to arrest movement of the arm 16 in a position to maintain the valve 15 at an angle to the bore of the casing 10. The stop 22 is then adjust-- ed to arrest movement of the arm 16 away from the stop 20 and thereby limit the closing movement of the valve. After the desired adjustments have been made the cover 23 is secured in position, and the sealing wire 25 connected with the screws 24, and sealed to prevent unauthorized tampering with the adjustments.
It will be observed that the butterfly valve is supported on its axis in an off-center position, in sucha manner that the lower half will have the necessary additional surface to make its angle of incidence eifectlve. When the intake gases strike the angle of incidence, at a speed suflicient to move the valve, the latter will start to close, and thereby obstruct the passage of said gases, and this in turn will cut down the motor speed, the valve moving against the pressure of thespring 17. The incident angle of the adjusting the position valve is variablefby of arm 16. This may be accomplished by loosening the set screw and swinging the arm on the shaft 14 until the desired. angle is reached, and again tightening the screw. An increase in the angle of the valve requires lessgas velocity to close it and a decrease has the opposite effect. The spring 17 serves to open the valve upon the slightest drop in the velocity of the gas. For instance, as-. suming that the valve is adjusted to such an angle that a motor running 1,000 B. P. M. would cause suflicient gas velocity to start it to close. If the spring were not present the valve will be immediately closed and would remain so until the motor had dropped to a very low speed. The effect of the pressure of the spring however, is to force the valve back to its normally open position upon the slightest drop in the gas velocity. The angle of incidence of the valve is maintained to insure initiation of closing movement, but of course after the valve starts to close, the sprin tension must be overcome to complete the c osing operation. It must be understood that after the valve has once started to close, the tendency to complete the operation is naturally greater than before, due to the increase of the incident angle, which causes more pressure and at the same. time requires less gas velocity. Therefore, it is necessary to introduce the spring to exert pressure in the opposite direction, to-oifset the additional pressure on the butterfly, and to balance the operation so that the valve will perform its functions at a constant or very slightly increased gas velocity. The closed position of the valve allowing the maximum motor speed desired is regulated by means of screw 22. Slight adjustments of the incident angle of the valve are accomplished by means of the screw 20 acting against the arm 16.
Having thus explained the nature of the invention and described an operative manner of constructing and using the same, although without attempting to set forth all of the forms in which it may be made, or all of the forms of its use, what is claimed is 1.
