Abstract
25,322. Smith, C. H. Nov. 15. Hot-air engines. - An engine, which may be worked by air, or mixtures of air and other fluids, is provided with major and minor cylinders A, D connected to oppositely-disposed cranks. The fluid, which is supplied from a heater through ports R, N, L controlled by a slide valve K, after performing the power stroke in the end A' of cylinder A, is exhausted, preferably through a cooler connected with ports P, Q, to the end A<2> of the cylinder, where it is compressed on the next forward stroke and passed through ports M, 0, T to the end D<1> of the minor cylinder D. During the next forward stroke of the piston E, the fluid is forced into the heater through ports O, S. The end D<2> of the minor cylinder D is always in communication with the heater. The passages may be controlled by flat or conical valves controlled by an eccentric or cam.
