IMPROVEMENT IN GOVERNORS.

F @te tlgettl rentrer in in tigen what atmt mit making am if the, smut.

TO ALL WHOMIT MAY GONCERN:

Be it known that I, JoHN W. HAYES, of Kittery, in the county of York, and State of Maine, have invented anew, and useful Improvement inl Governors; and I do hereby declare that the following is a full, clear, and p exact description thereof, which will enable those skilled in the art to make and usci-the same, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to improvements in governors for regulating the motion of stealn-engines, and for other purposes.

And it consists in operating the throttle-valve by means of a sleeve on the governor-spindle, the sleeve having inclined planes and wings, and being free to revolve with the spindle within a cylindrical cup, as herein- J after described.

Figurel represents a`sectional elevation Vof the governor and its attachment to the throttle-valve, the sec- /f tion being through the line asv-xo'ig. 2.

Eigure 2 is a sectional horizontal view from the line yy 'of iig. 1. 'Similar letters of reference indicate corresponding parts. A is the cylindrical cup, which is firmly attached to the plate or bed B, and which supports theopera'tive j parts of thergovernor.

i C is the governor-spindle,

D is the governor-lever, and E is the rod by which motion is imparted to the throttle-valve F, as seen in the drawing. G s'the steampipe. l The spindle C is revolved by a belt on the pulley H, or it may be revolved by gearing, if more convenient `or desirable. j v

Near the lower .end of the spindle thfe'eis a transverse bar,r, with friction-rolls J upon its ends. This bar. `is attachedA to and revolves with the spindle C. I l iK is a sleeve on the spindle, the vertical motion of which operates the lever D, andimparts motion to the throttle-valve through 'the rod'E and short lever; E.

This vertical motion isrprodu'ced by two circular inclined planes, m m, on the bottom of the sleeve.

As the spindle is revolved in thedirection of the arrow, the tendency of the friction-rolls J is to raise the sleeve vertically a distance equal to the line rn, which is the pleasure of its variation.

The tendency of the revolving arm z', and the contact ofthe rolls J, is to not only raise the sleeve or allow it to descend according to the velocity of the motion, butto revolve it; and for-the purpose of couteracting, to some extent, and regulating this rotating niotion, I provide the sleeve with wings o o andballspp, which balls rest upon the inclined bottom of the interior cylinder R.

This cylinder slips loosely into the main cylinder A, upon the bottom of which it rests, as seen at s.

When in a'state of rest, the balls p will naturallyrbll down on the inclined bottom of R until they come in ,contact with the sleeve.

When motion'is imparted to them bythe revolution of -thc wings, the centrifugal force will throw them up from the sleeve thereby operating with greater power to retard the rotating motion of the sleeve.

When the engine is running at the required speed, the balls would occupy the positionseen in the draw' ing, and the friction-rolls would bein contact 4with the middle of the inclined planes.

l When in this position, any variation in 4the speed of the engine must either raise or lower the sleeve which imparts motion to the throttle-valve, either opening or closing;it, as before stated.

The cylinder A may contain more or less oil for the reductioniof friction.

The upper end of the spindle is supported by a yoke, T, which rests on and is attached to'the head of the cylinder A, marked u.

soms 2 V is afstand which forms a. fulcrum for the lewe:` D. W is an adjustable weight on the lever D; I claim asnew, and desire to sc-:ure by Letters Patent- 1. In combination with a governor-spindle, the sleeve K, ywhen constructed with the inclined planes m m and wings o o, substantially-as described.

2. The interior cylinder R, with its inclined bottom and the balls pj@ nrtnngedsubstnntially as described, in combination with the sleeve K.'

3. The transverse bar 'i on the spindle C, in combination with the inclined planes m m, substantially #sand for the purposes set forth.
