The operation of nay-improvements is as follows: With the parts as shown themovtive fluid, entering port 9, flows through the 1eft-hand inlet-port 6 into the left-hand cylinder 2 to drive the piston 3 therein outward 5 and draw in the piston 3 in the right-hand cylinder to force out the fluid from4 this cylinder through exhaust-ports 7 and 10. When piston 3 in right-hand cylinder 2 reaches a position to bring .its bumpennut 22 into conxo tact with the .spring 21, it compresses the spring until the resistance from motive. pressure on the opposite ends of valves and 16 is overcome, when yokes 13 will be swung to carry the valves 15 and 16 to their reverse i 5 positions to open the right-hand inlet-port 6 and left-hand exhaust-port 7 and reverse the flow of the motive fluid.

Water, steam, compressed air, or other fluid may be 'employed to drive the motor, zov and hence I consider myself at liberty to employ any fluid for the purpose, and I do not restrict myself to the precise details set forth, but consider myself at liberty to make such slight changes and alterations as fairly fall within the s irit and scope of my invention. Having fu ly described my invention, what I claim as new, and desire to secure by Letters Patent, is

1.v In a Huid-motor, the combination with 3o"eylinders arranged in tandem, a valve-cham ber between them, istons in the cylinders, and a rod secured to oth istons and extendin through the valve-chamber, of hinged o es on the valve-chamber, inlet and exaust valves supported solely by said yokes and shifted thereby when the yokes are moved by the movementof the pistons.

2. In a fluid-motor, the combination with cylinders arranged in. tandem, a valve-cham-v 4o ber between them, pistons in the cylinders,

and a rod secured to both istons and extending through the valve-c amber, of inlet and exhaust valves'in the valve-chamber, hinged'yokes supporting said valves, s rings 4 5 secured to said yokes, and means on t e rod.'

to engage the springs and throw the yokes and valves.

3. In a fluid-motor, the combination withl cylinders arranged in tandem, a valve-cham- 5o ber between them having a central horizontal partition, pistons inthe cylinders, and a rod secured to both pistons and extending through'the valve-chamber, of an inletvalve in the valve-chamber above the partition, an exhaust-valve in the valve-ehamber below the partition, hinged yokes supporting both valves, and means on the rod for moving the yokes.

4. In a iluid-rnotor, the combination with cylinders arranged in tandem, a valve-cham 6o ber between ,them having a central horizone tal partition, pistons in the cylinders and a rod secured to both pistons and extending through the valve-chamber, of an inlet-valve in the valve-chamber above the partition, an' 65 exhaust-valve in the chamber below the partition, inlet and exhaust ports in both ends of the valve-chamber, adjustablev seats'in the r inlet-ports, and hinged yokes on the ends of n the valve-chamber affording the sole spport 7o for the valves. l n" 5. vIn a fluid-motor. the combination with a valve-chamber havin ports in its ends, of sleeves screwed into the ports -and constituting adjustable valve-seats, a -valve be- 7 5 tween the ports having contracted extensions proj ecting through the sleeves but outof conta'ct therewith, swinging yokes and screws thereon engaging the ends of t e :vaine extensions and supporting the valve'.

6. The combination with a valve-chamber having a horizontal partition therein andan inlet at its to 'and an exhaust at its bottom, of an inlet-va ve in the upper portion of the; chamber to alternately close and open ports 8 5 in the ends of the chamber, an exhaustrvalve in the lower portion of the chamber to alternately open and close ports in the ends of the chamber, yokes hinged to the ends of the chamber, screws in said-yokes engaging lthe 9o ends of the valves and sup orting them, and springs secured to said o es to receive the builing means to move t e yokes and valves.

In testimony whereof I have signed this specification -in the presence of two subscribing Witnesses.
