ings, to which reference is made.
Let A B C D E F in the drawing represent a water ram of the usual construction, syphon form, A B representing the main pipe, C outlet valve, D air vessel, E secondary air vessel, F rising main `being essentially the ram, delineated and described in Ewbanks Hydraulics and Mechanics, Greelys edition, 1848, pages 370, fig. 169.
The improvements which I propose tomake consist in the first place of an air chamber and conduit Gr, Gr, placed outside and around the orifice of the'air valve I-I, and carried up above the surface of thc water in which the working parts of the ram are immersed, in order to secure access of the air to the air valve, without which protection the air valve would be inoperative and the machine subjected to the imperfect act-ion resulting from the absorption of airA in the air vessel by the pressure of the fluids. This chamber and conduit need not be in the form represented in the drawings, but (espe` cially in large machines) a continuing chamber of size suicient to admit access to the air valve H without deranging the other parts of the machine.
At the lower termination of the ram containing, or inclosing and surrounding the,
outer valve and its spring-which valve I arrange to act horizontally and to be kept on, and drawn to its seat by a spring, (spiral 'or otherwise)-I erect-a chamber K of-sufficient height tobe elevated above the level of the water in which the ram stands,with an outlet to permit the water as it accumulates from the valve, to pass olf at the said level. close it J, whenever it may be desirablev to This outlet has a valve or door to do so for the purpose of access to the valve l C and its spring, and the removal of the accumulated water to e'ect that purpose.
I claiml l. The improvement of the'water ram as usually constructed by the addition to the lower or secondary air chamber on the outside of it, surrounding and protecting the` external orifice of the air valve; of an air chamber or conduit which shall exclude the access of water to the said valve, whenever the lram shall be immersed in water to a point above the level ofsaid valve, by which improvement I am, for certain purposes enabled to work my machine when immersed in water.
2. I also claim the employment of a water chamber at the termination of the' ram, inclosing and securing the outlet valve in the manner set forth in the above specification.-
