`Specification of Letterslatent.

Patented Nov. 30, 1909.

Application filed September 21, 1908. Serial No. 454,049.

To all 'whom t may concer/n:

Be it known that I, ANTON MILL, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Fluid-Motors, of which the following is a specification.

My invention relates to an improvement in iuid motors and more particularly to a water motor of the reciprocatory type, adapted to be actuated by ordinary water pressure and suitable for driving light machinery, such as a Washing machine, or, other similar devices employing reciprocal motion.

The object of the invention is to provide a motor of this class, employing an oscillating type of piston, in which the parts will be few and simple, of cheap construction and of convenient and eiicient operation.

The features of the invention are more fully set forth in the description of the accompanying drawings, forming a part of this specification, in which Figure l is a front elevation of my improved uid motor. Fig. `2 is a section on line w, Fig. 1. Fig. 3 is a section on line o, o, Fig. 1. Fig. 4 is a detailed top plan View of a base plate, illustrating the exhaust ports. Fig. 5 is an enlarged detailed side elevation of valve with cylinder shown in section. Fig. 6 is an enlarged detailed side elevation of the oscillating piston, with piston casing shown in section.

Preferably, the motor consists of a flat base plate 1, upon which is bolted a cylinder 2 of a type suitable to a rotary or oscillating engine.

l3 represents a work shaft upon which is fixed a sleeve 4, having a blade 5, constituting the oscillating piston.

6 represents a stationary member containing the inlet chamber 7, and the exhaust chambers 8, 9, upon each side thereof.

10 represents a supply inlet for chamber 7, admitting water to the motor. This stationary member forms a segmental portion of the cylinder, there being an annular space between its inner end and the sleeve 4, in which slides the valve 12.

Chambers 8, 9, have outlet ports 14, 15, re-

spectively, and chamber 7 has inlet port 16, these ports open radially toward the center.

The valve is divided into two compartments 17, 18, each of which is open at its outer end to communicate freely with the interior of the cylinder, and these compartments are provided with ports 19, 20, respectively, which communicate alternately with ports 14, 16, and 15, 16, as the valve is shifted. The chambers 8, 9, are provided with outlet ports 21, 22, communicating with the common exhaust passage 23, preferably formed in the base 1, to conduct the water from the motor. The ends of the lvalve are preferably provided with springs 24, extending outwardly toward the periphery of the cylinder and bent forwardly in position to be engaged by the oscillating piston. The piston consisting preferably of a plate 5, attached to the sleeve 4, and having the plates 25 bolted upon opposite sides thereof. The plates 25 have projections 26, 26a, adapted to strike the springs 24 and valve respectively for shifting the valve.

27 represents piston packings.

In operation, the water is admitted into the chamber 7 and flows through port 16, into the valve chamber 17, flowing out through the outer end and moving the piston to the right of the position shown in Fig. 3, the water upon the other side of this piston flowing through the open end of valve lcompartment 18, through ports 20, 15, into the chamber 9 and thence out of the motor.

As the piston completes its movement to the right, the projection 26a will strike the spring 24, compressing it, until the projection 26 contacts the valve, shifting the valve so as to change the ports from oneAV position toward the other after which the spring will complete the final movement of the valve, so that the ports 19, 20, cover the ports 14, 16, respectively, reversing the water pressure on the piston for moving the same in its opposite direction.

Having described my invention, I claim In a fluid motor, a cylinder and concentric work shaft, a stationary segmental member comprising inlet and outlet chambers and ports located at the outer periphery of the cylinder, a slide-valve controlling said ports located between the Work shaft and the inmovement to reverse the How of the Huid,
