Description:

"The nature of this invention consists in the direct application of balance valves for the induction and eduction of steam into and out of a steam engine cylinder, in combination with an arrangement of mechanism whereby the action of the induction valves are so regulated by the governor as to admit into the cylinder, only sufficient quantities of steam to maintain the required uniform motion of the engine."
