WATER-MOTOR.

SPECIFICATION forming part of Letters Patent No. 478,457, dated July 5, 1892.

7 Application filed July 14, 1891. Serial No. 399,511. (No model.)

To all whom it may concern:

Be it known that I, BENJAMIN S. PARTRID GE, of Jacksonville, in the county of Duval and State of Florida, have invented a new and useful Improvement in Tater-Motors, of which the following is a full, clear, and exact de-' scription.

My invention relates to motors in which water is employed as the motive agent; and its object is to provide a device of this character adapted for connection to Artesian wells, and wherein with a low pressure of water a high degree of power may be obtained for actuating machines of various kinds and for various purposes.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the water-motor. Fig. 2 is a plan view of one of the powercylinders and its valve chest, the supplypipe appearing in horizontal section. Fig. 3 is a transverse sectional view taken on the line a: 00 in Fig. 1. Fig. 4 is a side elevation of the motor, the power-cylinders, and their valvechests appearing in vertical section. Fig. 5 is a longitudinal section of one of the valve-chests, taken on the line y y in Fig. 1. Fig. 6 isaperspective view of one of the valves of the motor. Fig. 7 is a vertical section of one of the pistons 0f the power-cylinders, the piston-rod appearing in side elevation; and Fig. 8 is a side elevation of the same, the piston-rod appearing in transverse section.

A A are the two valve-chests of the motor, each provided at its top with an inlet-port, to which is connected a pipe B, leading from the water-supply and at its bottom with an outletport 0 in alignment with the inlet-port, as shown best in Fig. 4 of the drawings. At one side of each of the valve-chests is formed a power-cylinder D, which cylinders face each other, and in each of them is fitted a piston E, secured to the ends of a power-rod F. On the power-rod F are secured arms f, which as the rod reciprocates are adapted to come in contact with collars h on a rod I-I, movable longitudinally above the power-rod, as shown in Figs. 1 and 3 of the drawings.

In each of the valve-chests A is mounted on a central shaft G an oscillating valve G, provided with upper and lower curved wings g and g, which extend toward each other and are adapted to alternately open and close the inlet and outlet ports of the valve-chests. Upon the outer end of the shaft of the lefthand valve G is mounted a crank-lever I, the lower end of which is connected by a 'rod 1' with a crank-lever 1 mounted on the outer end of the shaft of the right-hand valve G, so that as one valve is actuated the other valve is simultaneously operated.

To the upper ends of the crank-levers I and I are pivoted casings K, into which enter the ends of the rod H above mentioned, and upon the ends of said rod are coiled springs K, having a bearing between stops or collars on the extremities of said rod and theinner ends of the casings.

The crank-levers are alternately locked to hold the valves temporarily stationary by means of spring-catches J, secured at their outer ends to the exterior of the valve-chests and having notches j between their extremities, adapted to engage pins j, formed on or secured in any proper manner to the cranklevers near their centers. Said spring-catches are adapted to be disengaged from the pins of the crank-levers by the contact with their downwardly-curved inner ends 70 of trips 70, secured upon the above-mentioned rod H.

M is a pump, which in this instance utilizes the power of the motor for raising water, and may be a common double-acting deckpump. The cylinder of the pump corresponds in length to the length of the stroke of the pistons of the power-cylinders, and the powerrod F, which passes. directly through the pump-cylinder, is provided within the same with a piston M of less area than that of the pistons of the power-cylinders. I desire it to be understood, however, that I do not limit myself to the application of the motor to a pump, as it may be employed for operating various machines and for various purposes.

The operation of the motor is as follows: The parts being in the position shown in Figs. 1 and at, a slight movement of the rod I-I farther to the left by the contact of the lefthand arm f on the power-rod F with the lefthand collar 72. on the rod H causes the lefthand trip on said rod to engage with the end 70 of the left-hand spring-catch J and depress the same, thus releasing the crank-lever I. Thereupon the spring K, previously under compression in the right-hand cylinder K, reacts, causing said cylinder to move to the left, and by reason of the connection of the casings K with the crank-levers I and I and the connection of said levers with each other causes the valves E to turn in the direction of the arrows shown in connection therewith in Fig. 4, so as to close the inlet and open the outlet port of the right-hand valve-chest and permit its contents to be suddenly discharged and simultaneously close the outlet and open the inlet port of the lefthand valve-chest, the inlet of water to such valve-chest acting to force the power-rod and its pistons to the right. At this time the right-hand arm f on the power-rod F engages the right-hand collar h on the rod H and forces said rod farther to the right,thuscompressing the left-hand spring K in its casing. As these movements of the rods F and II and the valves E take-place, the notch of the righthand spring-catch J engages the pin j of the crank-lever I and the valves are thus temporarilylocked in stationaryposition in their chests. The movement of the rods F and II to the right continues until the right-hand trip 7c on the rod II engages and depresses the right-hand spring-catch J, whereupon a reverse action takes place, and these alternate actions continuing the pump or other machine to which the motor is applied is continuously operated.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a motor, the combination, with oppositely arranged and spaced valve-chests and opposing cylinders at one side of the valvechest, of spring-actuated valves in the valvechests, means for alternately locking the valves stationary, pistons in the cylinders, a power-rod connecting the pistons, and means ,for releasing the valves, substantially as described.
