Description:

Abstract:

Our invention consists in an improved arrangement of keeping the steam port surfaces of the side pipe and of the cylinder in proper steamtight contact in such a manner, that the expansion and contraction of the cylinder and side pipe, caused by variations in their temperature, has no influence thereon.

Claim:

The expansion and contraction of the cylinder and side pipe has always been a very serious objection in "side pipe engines" as arranged heretofore; to keep the port surfaces in proper contact it required a constant attention in the way of adjusting, and readjusting, in order to avoid leakage at one time, and an undue pressure between them at another time. By our improved arrangement this objection is completely overcome. We finally wish to state, that, having subjected our improved arrangement to practical trials, it fully and practically exhibited the advantages, we claim for it.
