In many localities, where ordinary pumps and necessary gear are employed to first raise and tli: n distribute water, the whole machinery is multiplied, cumbersome, and costly ; and the want of a compact, combined steam lift and force pump is apparent. The engravings shown herewith represent two modifications of this useful combination one a submerged pump, the other apump with suction pipe leadingin the desired direction to reach the well or source; each com bination having for a motor a rngle steam cylinder with its piston and ram formed in one piece and provided with two separate throttle or regulr ting valves, to contjfol the quantities or pressures of steam flowing through sept rate passages, to each end of the cylinder, suited to the character of the duty required. The ram is made to enter the ? orce puaap barred and feas a reduced end passin through the bottom. ."; the pump and stuffing box just below the channels leading to the valve box. The engine and force pump cast and finished in one piece, is supported upon a cast frame with a base or channel plate, beneath which is attached a pipe in communication with the lateral channel formed therein ; the connection of this pipe with the lift pump, forms a condsit for the same. The pump rod coupled to the protruding portion of the ram passes down through the conduit pipe and is guided truly within the pipe, when length requires it, by one or more ingeniously formed pipe couplings which have water-ways around a central core or (iiapSsmgm, irtiSah earn m bored out to fit and guide the rod in its movements connected to the working parts of the lift pump. When desired to operate, steam is admitted and regulated on its way, accordingly as is the depth at which the lift pump is placed, to one end of the steem cylinder, and the force of the resistance to be overcome to the other end of the cylinder, until the desired regularity of reciprocation is attained. The water is then made to flow from the well or scource up through the conduit pipe and lateral channel and pipes to the tank or heater. From the tank or heater the water is supplied at any temperature to the force pump, which delivers it into the boiler or other vessel, under pressure either from steam or hight of column. It is obvious that the duty of either pump can be increased" or lessened, or either pump can be worked separately, by withholding the supply of water from the force pump, in the one case, or by withdrawing the coupling key which connects the lift pump rod, in the other case. The pumps shown in the engravings are single acting, but double acting ones are substituted, as required.
