HHIHHHHII UNITED STATES FREDRICK M. BROWN, OF WARREN, RHODE ISLAND.
IMPROVEMENT IN STEAMHENGINE GOVERNORS.
Specification forming part of Letters Patent No. 159,299, dated February 2, 1575; application filed December 19,1874.
To all 'whom it may concern Be it known that I, FREDRICK M. BRowN, of Varren, Bristol county, Rhode Island, have invented a new and useful Improvement in Governors7 of which the following is a specication:
The invention will rst be fully described, and then pointed out in the claim.
Figure l represents a side elevation of the governor, showing in dotted lines the position ot' theballs, arms, and levers and rods when the speed is increased, and Fig. 2 is an edge view, partly in section.
Similar. let-ters of reference indicate correspondiiig parts.
This governor is contrived similar to some governors now in use, the peculiar feature ot' it bein g the upward movement ot' the balls on the arms when the speed diminishes, and the downward movement when the speed increases, and in the levers and rods by means ot' which these movements are produced.
A is the base or stand, to which is attached a central stationary spindle, B. C C are the ball-arms, hinged, at the top ofthe spindle, to a block fitted thereto. The joint is seen in Fig. 2, where D represents the block, and E a nut on the eXtreme end of the spindle. D represents the balls. These balls are bored out and fitted to the arms O' C', so that they slide thereon. C U are levers attached to the blocks F F, which latter are on the arms, where they are rigidly fastened. G G are small clevises on the levers. D D are rods hinged to the clevises G G, and attached to the balls by means of the eyes J J, where they are made adjustable by means of set-screws K. The clevises G .G are also adjustable on the levers C C. The levers are bent to an angle often degrees, more or less, with the slide N, to which the valve-lever is attached y by means'ot the projecting lug O, which lug works up and down in the slot P ot' the base. Q is an adjustable collar on the spindle to stop the upward motion of the balls.
No novelty is claimed for the slide and thiinble or manner of communicating with the valve. The novelty consists in a device for altering the plane of the rotating balls during their revolution, substantially in the manner described.
I do not confine myseltl to the particular manner shown, but design to employ any mode or device by which the ball-arms are shortened and lengthened by the application of centrifugal force.
Having thus described my invention, I claim as new and desire to secure by Letters Patentrlhe combination, with arms O O', pivoted to the stationary spindle B, of crooked levers O C and sliding balls D D, connected by pivotcd rods D' D, as and for the purpose specified.
