One of the objects of my invention is to In the following description and in the perfect devices of the above type so as to claim, parts will be identified by specific provide a steam engine of high efficiency names for convenience of expression but 75 20 compared with such devices now known and they are intended to be as generic in their which at the same time will be simple in con application to similar parts as the art will struction and economical in its consumption permit. of Water and fuel. For the purpose of this disclosure the in Another object of the invention is to pro vention as shown in connection with the 80 25 vide a simple form of engine free of any base portion of a standard form of hori steam controlling valves and promptly re Zontal type, four cylinder, two cycle engine sponsive to a sensitive control for varying in order to demonstrate the adaptability of the working capacity of the engine. the novel features to conventional structures As an incident to the economical actua now on the market.
