Description
UNITED STATES PATENT OEEIoE.
WILLIAM NIcHOLs, OE ELMIEA, NEW'YOEK.
IMPROVEMENT IN STEAM-ENGINE G OVERNORS.
Spcciication forming part of Letters Patent N0. 57,953, dated September ll, ISGS.
To alt whom fit may concer/n:
Be it known that I, WILLIAM NICHOLS, of Elmira, in the county of Chemung, and in the State of New York, have invented a new and useful Governor for Steam-Engines; and I do hereby declare that the following is a iull, clear, and exact description thereof, reference being had to the accompanying drawing, forming a part of this specification.
The drawing is a view in elevation showing my improved governor.
My invention consists in thenew and useful mode of constructing a governor hereinafter described.
In the drawing, A shows the valve-rod, and B the hollow shaft in which the valve-rod plays up and down. C is a collar, with short lateral arms, and is fastened to the hollowshaft B. D are the two governor-balls, having extending upward from them short arms D of a length about equal to the diameter of the balls. The two arms D are pivoted at a to the collar-arms (J.
The upper ends of the arms D are made into the shape of cams D2,`so as to raise the weight-ball E in proportion to the divergence of the governor-balls.
E is the weight-ball, which rests upon the heels of cams D2. This weight-ball is perforated by a pin, 0, passing through a slot, t', in the hollow shaft and through the valve-rod, so that the weight shall be fast to the valverod, and yet be capable ot' sliding up and down upon the hollow shaft through a space equal to the length of slot t', which is equal to the vertical play ot' the valve.
F is a spiral spring around the upper part of hollow shaft, and presses against the collar G and the weight-ball E, so as to assist `in overcoming its inertia and force it to act instantaneously.
It would be practicable to use a stronger spring and a weight-bali made in the form of a mere disk for the spring to act upon, but I prefer the construction shown in the dra wing.
The operation of my invention is evident. The divergence of-the governor-balls D is in proportion to their speed, (which I prefer to have at about four hundred revolutions per minute,) and the degree of lift imparted to the weight-ball and the valve-rod by the cams D2 is proportionate to the divergence of the governor-balls. As the balls D diverge they bring the cams D2 to operate gradually against the under side of weight-ball E, raising it more or less, the greatest raise or lift being when the points ofthe cam are in contact with the weight-ball, which occurs when the governor-balls are at their greatest divergence. As the speed slackens the balls approach, and the weight-ball descends so as to force the valve-rod downward.
Perfection and sensitiveness ot' operation and cheapness ot' construction over governors known to me are claimed as advantages ot' my invention.
I am aware that a patent has been granted in' which a weight-ball (for operating' the inner ends of the bent levers supporting the governor-balls) is fastened .to a spindle playing up and down in a hollow shaft, and that a spiral spring has been used in combination with such a weight-ball; I therefore, in this specification, disclaim any title to said devices, orany other claimed in said patent, and limit my claim to what is new in this application.
What I claim as myinvention, and desire to secure by Letters Patent, is-
The arrangement, substantially as described, of the balls D, arms D', cams D2, and weight E, for the purpose set forth.
In testimony that I claim the above-described invention I have hereunto signed my name this 17th day of August, 1866.
WM. NICHOLS.
Witnesses EDM. F. BROWN, J o. C. CLAYTON.
