Abstract:
The object of my invention is to simplify and perfect the construction of governors of the class or type of those located upon the crank shaft or countershaft of an engine, and to provide, in a governor of such type, a system of gravity balancing weights by means of which the degree and rapidity of regulation of the governor may be made more fully and effectively available than heretofore., To this end, my invention, generally stated, consists in the combination of a primary centrifugally adjustable weight, adapted to be connected to an adjustable cut off or regulating device, and a secondary weight in gravity balance with the primary weight and connected to the supporting wheel or case so that its centrifugal force of adjustment is reduced to a minimum by being caused to act substantially through or in line with its pivot.
Claim:
The combination, in a governor, of a primary centrifugally adjustable weight, and a secondary weight in gravity balance with the primary weight and connected .to the supporting wheel or case so that centrifugal force tending to hold it in normal position shall act through or in line with its pivot. |
