To all w/iom t may concern: l
Be it known that l, PETER T.' Cormano, citizen ot the United States, residing at Dayton, in the county vof Montgomery andl State of (lino, have invented certain new and useful improvements in Reciprocating Fluid-Pressure Motors; and-I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and ligures ofrcference marked thereon, which form a part of'this specification. A A
This invention relates to new' and useful improvements in fluid-pressure reciprocating motors designed for furnishing power for the operation ot a variety of machines usually operated by hand, such for example,
' as washing machines.
.The object of the invention is to provide a motor of the above type which combines.
simplicity and etliciency to the wdesired. extent, and owing to the simplicity ot which, itv is adapted to be placed in the hands of persons unskilled in mechanical knowledge. To the foregoing ends, springs or their equivalents are entirely eliminated as means for imparting any of the valve movements.
Preceding a detailed description of the invention, reference is made to the accompanying drawings, of whichq Figure l, is `a longitudinal sectional view of a motor embodying my improvements. ln thisview, the-piston is shown approaching the end ot one of its strokes with the in. let valve at the initial point of movement.
vlig. 2, is a sectional elevation ot one end` ot the motor showingUthe piston at one end oi its stroke or justbeginning its reverse movement. The inlet valve in this view is shown to be completely reversed from the position shown in Fig. 1. Figi 3, is a cross sectional view-throu h the valves and piston on the line t (l o Fig. l. Fig. 4, is a detached view of the inlet valve with one of its tubular extensions sho .vn in section.
ln a detail description of the invention,
chamber l and the latter rod communicating with the exhaust chamber. piston rods extend out ot the motor cylinder through stu'ing boxes 7 in the cylinder heads or abutments 2 2. The tubular piston rod 6 connects with the faucet orv other connection (not shown) through which the motive fluid is introduced, and rod 9 connects with an outlet pipe 10, which in turn, is connected to a iiexible pipe or other means (not shown) to carry` oil the water. Also connected with the pipe 9 is a rack 11, a portion of which is broken oil, forming the means for transmitting the power to the machine to be operated.
Mounted in the exhaust chamber 5 andy having seats on the outer sides of the piston, are double puppet exhaust valves 12 which are connected by vanos 13 or otherwise, and have stems 14 which alternately engage the Cylinder heads or abutments 2 2 in unseating said valves at each end of the piston stroke. After said valves are unseated, their movement is completed by the live fluid to be again referred to.
Mounted within the inlet chamber 4, is a double puppet inlet valve 15 adapted to alternately seat on seats on the interior of the piston. This inlet valve has tubular extensions 16 16 which form auxiliary valves for.
unbalancing said inlet valve and thereby insuring a complete stroke oit' Asaid inlet valve These tuliiilar L' by` the live iiuid. The tubular extensions 16 and 16 are connected to the valve and are provided with ports to permit the live fluid to pass :trom-the chamber el into said tubular extensions alternately.` The ends oft said haust valves nearest the abutment.A
thereafter, unseats said valve and tubular extensions alternately engage the cylinder heads orabutments 2 2' as the piston approaches said heads or abutments, and the slight continued movement of the piston allows the live fluid 'which has entered said tubular extension, to exert a pressure against the cylinder head or abutment and thereby complete the movement of said valve to its oppol the direction of the flow Yofthe motive vfluid 'y is reversedpist-on as the end balanced position and balances the pressurel 'of-'the fluid on both sides of The operation may be described as follows: VViththe valves ,in the position shown in Fig. 1, the live fluid vpasses into chamber 4: through the hollow 'piston rod 6, and thence past the inlet valve 15 and into and through the tubular extension 16 to the interior of the cylinder, where it will exert itself to drive the piston to theleft. In the meantime, the exhaustv fluid passes the left exhaust valve into the chamber 5, from whence it passes into the hollow piston rod 9 and escapes through the outlet 10. When the piston approaches the end of its stroke, the end of the tubular extension 16 will engage t-he head or abutment 2 and thereby unseat the inlet valve 15. The live fluid, however, will not pass to the frontof the of the tubular extension 16 and the abutmentQformA an auxiliary valve. The piston will therefore, continue in its movementA to the left while the exhaust valve stem 14- makes contact with the cylindei1 head' or abutment 2 and unseats the exhaust valve. This places said exhaust valves in a the piston and said piston will be at rest. The live fluid exerting itself against the abutment 2' in the tubular extension 16, will then complete the movement'of the inletvalve and allowl the live fluid to pass to the side of the vpiston which is nearer the said abutment. The pressure of the live fluid on that side 'of the piston will then complete the movement of the exhaust valves and said piston Awill vbein its movement in' the opposite direction.
-l/Vhile I have shown and described the valves mounted in movable chambers, and the valv' I'engaging stationary abutments, 1 do not @wish to be understood as limiting and before it Av,is completely ing an inlet and puppet inlet valve with'hollow stems for' my invention to these vparticular features, for the reason that the chambers may be stationary and the abutment-s movable without departing from the spirit of my invention.
I claim:

In a lluid motor, cylinder, a piston, inlet and exhaust valves, abutments, said inlet valve being constructed and arranged to cooperate with said abutments at each end of the-piston stroke to form an auxiliary valve to prevent the motive fluid from being reversed until the exhaust valve is forced from its seat, thereby causing a completde, reversal of the valves by the motive 3.
