| Abstract:
This invention relates to speed-governors for engines, and particularly to governors of the centrifugal type, such as are commonly employed in connection with, steam- engines. One object of the invention is to produce a governor having a centrifugal mechanism of a form in which, without complication of construction, provision is made for a wide range of adjustment and of sensitive action, and to this end I employ an arrangement in which the weights have a substantially rectilinear or radial movement toward and from the axis of revolution, while being connected with the parts actuated thereby through a simple arrangement of levers. Another object of the invention is to produce a centrifugal mechanism which, while enclosed compactly within an oiltight casing, is at the same time readily adjustable at any time, even while the governor is running, and without opening the casing. To this end I employ a construction in which the centripetal spring of the mechanism is arranged coaxially with the centrifugal mechanism, and is adjustable by means of a member which extends outwardly through the side of the casing, in a manner hereinafter described. Another object of the invention is to improve the valve which is connected with, and actuated by, the centrifugal mechanism of the governor.
In Letters Patent of the United States No. 963,803, granted to me July 12, 1910, I have disclosed a governor provided with a governor-valve, or throttle-valve, in which the rotatable valve-member fits and turns within an outer fixed valve-member. In accordance with the present invention I have improved the construction of the valve disclosed in my said patent, by rearranging the parts so that the rotary valve- member embraces and turns upon an inner fixed valve-member, with resultant advantages which are hereinafter set forth.
Claim:
A governor having, in combination, a stationary sleeve; a shaft journaled in the sleeve; centrifugal mechanism carried by the shaft; a stationary casing carried at the end of the sleeve and inclosing the centrifugal mechanism; and means, for connecting the centrifugal mechanism with a governor-valve, comprising a sleeve slidable upon the stationary sleeve, and connections, between the sliding sleeve and the centrifugal mechanism, slidable through the wall of the casing. |
