An Improved System Applicable to Artesian Wells.

An Improved System Applicable to Artesian Wells.

An improved system, of special application to artesian wells, and designed for obtaining with a low pressure of water as a driving medium a large amount of power, has lately been proposed. The machinery to be actuated by this means may be of any desired construction, but a double acting pump works well, the piston in the middle pump being on a piston or power rod carrying pistons in cylinders near its ends, these cylinders being open at their inner ends and connected at their outer ones with the valve chest of inlet chambers through which the motor agent enters. In these chests slide cylindrical valves, their rims opening and closing the inlet and the outlet ports alternately, and the valves have each a central hub and radial spokes to form a discharge opening for the cylinders at the time the valves are seated over the inlet ports of the inlet chambers. At all times the valves are entirely surrounded or filled with motive agent, being thus constantly and perfectly balanced. Outwardly extending valve stems are pivotally connected with transverse pivoted arms, whose free ends are pivotally connected with each other by a rod, and this rod slides in hearings formed on arm secured to the power rod, the bearings engaging collars on the ends of V-shaped springs, having at their other ends collars abutting against collars secured to the rod, while the latter collars abut against spring arms secured to the valve chests. In operation, as the power rod moves in either direction, one of the springs is first compressed and then released, to force in one direction or the other the rod connected with the valve stems at the ends, thus alternately opening and closing the ports in each chamber.
