FLUl-D=PRESSURE MOTOR.

SPECIFICATION forming part of Letters Patent No. 590,228, dated September 21, 1897.

Application filed Julie 24:, 1896. st lifill NO. 596,771 (N0 model.)

To (0Z6 whom it may concern:

Be it known that I, WALTER IL KNIGHT, a eitizen of the United States, residing at New Brighton, in the county of Richmond and State of New York, have invented certain new and useful Improvements in I luid-Pressure Motors, of which the following is a specification.

My invention relates to means for automatically controlling the supply of fuel to the heater of a compressed-air motor in order that the quantity of fuel burned and the degree of heat generated will be in proper proportion to the amount of work being done.

In the particular form of mechanism which I have illustrated in the accompanying drawing by a diagrammatic View I have provided means for opening the throttle of the compressed-air reservoir and shifting the valvecontrolling device (the reversing-link) simultaneously with the opening of the cock which controls the supply of oil to an oil-heater which is adapted to heat the compressed air on its way to the motor.

In the drawing, A is a compressed-air reservoir, and B is the throttle-valve.

O is the heater-coil, communicating with the reservoir A through pipe D and with the distributing-chest E of the engine-cylinder F through the pipe G.

H is the oil-burner, supported beneath the heating-coil O, and H is the oil-supply pipe leading from the oil-reservoir K.

L is a turning valve or cook in the oil-supply pipe II.

M is the reversing-link of the engine, by means of which the engine can be run in either direction or stopped entirely.

N is the hand-lever, which controls the opening and closing of the throttle-valve I3 by means of the connecting-link N,and the shift ing of the link M through lever O and links 0 O and bell-crank O and the opening and closing of the oil-cock L through the eonnecting-rod P.

\Vhen the throttle B is closed and the link M is in central position, the oil-cock L is nearly closed, shutting off the main supply of oil and allowing only a sufficient quantity of oil to pass to keep the burner lighted. lVhen the handle is shifted to open the throttle-valve and run the engine in either direction, the oil-valve L will be opened to increase the flame of the burner for heating the air which is supplied to the engine-cylinder. If the speed of the engine is reduced, the supply of oil and heat of the heater will be proportionately reduced.

Though I have shown but one form of mechanism for automatically controlling the supply of oil to the burner in proportion to the amount of work being done by the motor, I would have it understood that I do not limit myself to this specific mechanism; neither do I limit myself to the particular form of valve-controlling devicethe reversing-link motion.

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

1. The combination of a motor, suitable valve-controllin g devices for the motor,a fluidreservoir, a heater communicating with the reservoir and with the motor, a throttle-valve, a burner for the heater, and a hand-operated device for simultaneously controlling the
