Letters Patent No. 98,216, dated December 28, 1869; (mtedaled December 24, 1869.

IMPROVEMENT m STEAM-ENGINE eovmuvons.

The Schedule referred to in these Letters Patent and making part of the same To all whom it may concern:

Be it known that I, CHARLES DOUGHTY ALLEN, of the city, county, and State of New York, have invented a new and improved Steam-Governor; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing, forming part of this specification.

This invention-relates to a new and useful improvement in governors for steam-engines, whereby they are made more useful than they have hitherto been, and consists in the construction and arrangement hereinafter described.

The accompanying drawing is a sectional elevation of a governor, constructed according tomy invention. Similar letters of reference indicate corresponding parts.

A is the stand, which is fastened in any convenient position for supporting the movable parts of the governor and operating on the valve.

B is the spindle, the lower end of which is connected with the valve-gear. It does notrevolve, but has a longitudinal or vertical motion imparted to it, by means of the rise and fall of the governor-balls O C, which are connected with it by the thimble 1), between the two collars E E, which are fast on the spindle.

11 represents an open sleeve, with which the balls are connected, as seen at g g, and which revolves around the spindle B. This sleeve is confined 1n and supported by the stand A, and is revolved by means oi'a' band on the pulley h. 7

dis the support, and j the box or guide for the sleeve F.

The spindle works through the standA on a feather and groove, as seen at h, which prevents it from rotatio The balls being connected with the top of the sleeve by their levers L L, and with the thimble 'D, by means of the jointed rods n n. it will .be seen that the riseaud fall of the bills will act directly on the spindlc, and through it on the steam or throttle-valve.

In starting the engine, the spindle B is' raised, by means of the ball 0, for letting on steam.

When the speed attained is sufiicient to raise'the balls, then centrifugal force will keep the spindle suspended, and regulate the motion of theengiue.

Having thus described my invention,

\Vhat I claim, and desire to secure by Letters Patent, is-.

The arrangement of the stand A, spindle B, and sleeve F, as herein shown and described. CHARLES DOUGHTY ALLEN.'
