citizen of the United 'Sthtes,;residing in- Newport, county of Campbelhand State of .Kentucky, jan d HExRYCJ C -nurnnns, a citi-- zen of; the United-States, residing in Cincin- 3 nat1,-.countyofHannltoinand State ot Ohio,

have inyented certain newand useful Iniprovements 1n lVat'erj-Abtors, of whichthe.

t V of the inlet val've,"the1e"" l'iilsth i ly'" ery strong suction around the open exhaust valve which, without any preliminary unseating, unseats the exhaust valve, and this unseating of the exhaust valve in the opposite side of the cylinder allows water to start exhausting from that side, while the full pressure of the water in the other end of the cylinder closes the exhaust Valve on that side. 7

The water enters through the tube 16 into the inlet chamber 7 in the piston 6 and, passes outthrough the open Valve into the right hand side of the cylinder, as shown In Fig. 1, closing the exhaust "alveon that side I and driving the piston to the left. The mo ment the valve stem of the inlet valve comes on the head. This inc os' in contact with the head 4 of the cylinder, the inlet valve is shifted from its seat 19- and the cup seats itself or almost seats itself l in of the water passing around the seat 0 the inlet valve creates suflicient back pressure to suddenly throw the valve to. the opposite side. The

aright hand end of the cylinder is therefore pressure is'transferred to the left "of the cylinder, which pressure in the left cut off from the inrush of wateriland the and end hand end of the cylinder is suflicie'nt to unseat the exhaustvalve and force itto its oppositeside. The exhaust valve is therefore opened on the; opposite side of the cylinder and the piston head is driven to the right,

and thus the motor drives the piston back and forth in the cylinder. In the oscillating rotatory typeof motor; Where the piston is mounted as a wing on the rocking or oscillatory piston rod, the valves are mounted in the same way to come in contact with the rotatory oscillation of the motor cylinder.

- Having thus described our invention what we claim as newand desire to secure by Letters Patent, 15:
