JOHN A. MYERS, OF LOUISVILLE, KENTUOKY.

HYDRAULIC MOTOR.

SPECIFICATION frmmg part of Letters Patent No. 223,943, dated January 27, Iseo.W

Application filed January 2, 1880. v

To all whom t may concern:

Be it known that I, JOHN A. MYERS, of Louisville, in the county of Jefferson and State of Kentucky, Vhave invented new and valuable Improvements in Hydraulic Motors; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and gnres of reference marked thereon.

Figure l of the drawings is a representation of the motor operating a fan. Fig. 2 is a central sectional view of the motor. Fig. 3 is a bottom view of the valve-box. Fig'. t is a central sectional view of the motor, showing the valves in another position. Fig. 5 is another bottom view of the valve-box. Fig. 6 is a plan view of the ante-water-chambers. Fig. 7 is a detail view of the double valve'.

This invention relates to that class of hydraulic motors for operating light machinery; and the main object is to produce a compact, effective, and cheap hydraulic engine that can beconveniently located for operating' the fan or fans in dining-rooms in the warm season,

or driving sewing-machines, turning-lathes,

and the like.

The invention consists in means for auto matically operating the valves.

It also consists in connecting the two sets of valves by means to insure their simultaneous"`movements in the operation of the piston.

It also consists in the novel combination of the parts, as will be hereinafter more fully set forth.

In the annexed drawings I have shown the engine operating a fan in a dining-room.

rlhe letter A represents acylinder; B, the upper cylinder-head with central opening; O, the stuffing-box 5 D, the hollow piston-rod; E, thepiston-head, suitably packed 5 and F, the valve-box. l

The letter G indicates a pipe suitably `secured and arranged alongside of the cylinder, forming the water-communication within the The upper portion of the cylinder, above the piston, is charged with water, and the same discharged through this pipe Gr. It will be noticed that this pipe is connected to the upper surface of the valve-box and registers with the opening a thereof. (See Fig. 2 of the drawings.)

By means of the iioor or horizontal partition b` the valve-box F is divided into two stories, the lower story containing the valveoperating mechanism and the upper story Water-chambers and spaces for the buttonvalves.

The circular plate H, closely fitting the lower end of the cylinder and resting upon a ledge at the upper end of the valve-box F, forms the lower head to the cylinder, and is provided with two water-passage ways or ports, a b. The passage-way a establishes the communication from the waterschamber l to the pipe G, and the passage-way 'b establishes the communication from the chamber I to the under side of the piston-head. lIhis plate is also provided with a central opening and ange, c, through which the piston d, carrying at its lower end the operating valve device, passes, the flange serving as a guide. The valvechamber K is also divided into two water-compartments by means of the vertical partitions c (see Fig. 3,) and one compartment is provdded with charge-openings and the other compartment with discharge openings, arranged in the top wall of the chamber, and induction and eduction passages arranged on the sides.

ber is arranged, at-one side of the center and at right angles to the charge and discharge ports, a shaft, M, suitably journaled, so as to be capable of an oscillating motion. To the outer ends of this shaft are secured the double valve-arms N, provided at their upper ends with the valves h. These valves are so arranged i'n their respective chambers that when one is opened, admitting water to its proper passage, the valve directly opposite in the other valve-chamberis closed, but the valve arranged on the opposite end of the other arm is opened, allowing the discharge. (SeeFig. 5.)

The antewater-cham-bers I I areiseparated from each other by means of a partition arranged at right angles to the chambers in the valve-chambers, and are each provided with the charge and discharge passageways or ports forming the communications with the upper and lower surfaces ofthe cylinder, there- Ioo by charging and discharging the Water alter- .nately.

The piston d, for operating the Valves, tits within the hollow piston-rod, and is provided at its upper end with an adjustable nut, t', and in connection with the screw-threaded cap It, attached to the lower end ot1 the hollow pistonrod D, acts as coupling means. The lower en d ot' the piston d is provided with a pivoted wedge-shaped block, P. acting against the inclined face of the member or arm R, attached to the shaft carrying the valves. The lower end of this block or member P is notched or recessed to receive one end ot the rod l, encircled by the spring m, for the purpose of keeping the member P in contact with the member R and pressing' it to the face of the member P with such force that it changes its position, and with it that ot' the Valves attached to it, whenever it passes the center of the shaft that carries the valves. The other end of the rod Z is so journaled or loosely suspended in the wall o1, as to be capable of a vertical movement with the piston` The operation of my hydraulic engine is as follows: `Wateris introduced from the supply or main pipe through suitable connections into the charge-compartment of the valve-chamber K, as indicated by the arrows in Figs. 3 and 5; thence into the an'te-water-chamber I', passing through port I), as indicated by the arrow in Fig. 2, which forces up the piston-head pro'- vided with the coupling until the member P acts upon the inclined face of the member R, the valve closing the passa ge-way and openin g the other passa ge-way.

reverses the direction `ofthe piston-head, which begins to descend, owing to the water passing upwardly through the passage-way G and tallin g upon the piston-head. The water thatfor'ced up the piston-head iiows out of the cylinder through the same opening into the ante-waterchainber I, thence down the discharge passageway, which .is now open, into the discharge This movement of the valves changes the course of the water andr valve-chamber,and through the Waste-pipe on the opposite side of the induction-passage, as indicated by the arrow in Fig. 3. In this way acontinuous reciprocating motion is imparted to the piston-head.

Fig. 2 ofthe drawings shows the water being emitted from above and the piston-head ascending.

From this explanation it will be perceived that the induction passage-ways serve also as eduction passage-ways for the water that is to sav,the water is vdischarged from the cylinder through the saine openings through which it was forced.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In a hydraulic motor, the combination, with a reciprocating hollow piston-rod, of a coupling-rod having at its lower end a wedgeshaped member acting against a member attached vto the shaft carrying the valves, for the purpose stated.

2. In a hydraulic motor, the combination, with a reciprocating hollow piston-rod, ot' a coupling-rod having at its lower end a pivoted wedge-shaped member provided with a notch or recess to receive one end of a spring-rod, for the purpose stated.

'3. rI he two sets of valves connected to a shaft common to both, -to insure their simultaneous movements, substantially as described, and for the purpose set forth.

' 4. In a hydraulic motor, the combination of the reciprocating hollow piston-rod, couplingrod 'with the wedge-shaped member, compressing-spring rod, shaft with acting member, and the two sets ot" valves, substantially as described.

In testimony whereof I have hereunto subscribed my'name.

JOHN ALOIS MYERS.
