IMPROVEMENT IN GOVERNORS FOR STEAM-ENGINES.

Specification forming part of Letters Patent No. 123,939, dated February 20, 1872.

To all whom it may concern:

Be it known that I, ISAAC S. SCHUYLER, of Brooklyn, E. D., in the county of Kings and State of New York, have invented an Improvement in Governors for Engines 5 andthe following is declared to be a correct description ofthe same.

A propeller-wheel has been revolved in a case containing water, and acting to move the throttle-valve upon any change of speed in the governor propeller. In governors of this character the speed may be such as to pro duce a partial vacuum in the center of the propeller, or else the water itself may acquire a rotary motion with the propeller. In either instance the action of the blades, in giving an endwise movement to the shaft of the propeller, will be irregular and unreliable, and vary according to the condition of the water near the wheel, instead of according to the speed of the propeller. Stationary ribs upon the interior surface of the case have been used to arrest the rotary movement of the water.

My invention consists in a series of revolving blades around the revolving propeller, and acting upon the water to force it upon the propeller in such a manner that there will not be any risk of the water being thrown from the center of the wheel, or caused to revolve with the wheel; thereby the action of the propeller will be rendered uniform and reliable, because the water will be caused to circulate against the propeller in a direction opposite to the motion thereof.

In the drawing', Figure l is a vertical section of the said governor, and Fig. 2 is a sectional-plan at the line .fr

The vessel a, is of a size and shape to contain the revolving blades b, propeller c, and actuating parts. The propeller c is upon a shaft, d, that runs within the bearings c e of the blades b, and the shaft d is sustained at its upper end by a tubular bearing, j', extending downward from the cover g. The propeller c is driven by the bevel-wheel h upon the shaft k acting upon a bevel or miter-wheel, Z, upon the propeller-shaft d, and the blades b are re` volved in the opposite direction by means of the bevel-gears m n. The shaft d is allowed to move endwise under the action of the propeller upon the liquid filling the vessel a and to allow of this movement the shaft al is squared or made with a feather where it passes through the miter-wheel l, so as to slide therein, said wheel Z being held in position by e and f.

The blades b may extend more or less above or below the propeller c in a curved or domeshape; and, by reference to Fig. 2 and the arrows marked thereon, it will be seen that the blades b act to force the water toward the propeller c; hence, the water will be in a more compact mass where the propeller is acting upon the same.

The size of the propeller and its speed are proportioned to the work to be performed.

I remark that the connection between the propeller-shaft and the throttlevalve of an engine, the gate of a water-wheel, or other power-regulator, is to be of any desired character. I, however, prefer and have shown the rod 1^ sliding through the gland s, and provided with the lever t, counterpoise u, and stops o o, as convenient devices for regulating the movement.

The shaft d, acting against the end of the sliding rod r, is not liable to the friction and risk of derangement existing in governors where the propeller-shaft passes through the stuiiing-box and revolves in a collar at the lever.

There will be but little friction or wear to the parts that revolve, because they are all immersed inthe water or other liquid made use of in the vessel a; and the operation of this governor will be very reliable, because the propeller will have a uniform resistance, and its shaft will move in either direction, ac cordin g to the speed of rotation and the power of the 'countcrpoise I prefer to employ a spring or steelyard for acting upon the lever t in place of the counterpoise, as such spring will act with an increasing force to resist the end movement of the propeller-shaft.
