IVALTER II. KNIGHT, OF NEIV BRIGHTON, NEW YORK.
FLUID-PRESSURE ENGINE.
SPECIFICATION forming part of Letters Patent No. 581 ,826, dated May 4, 1897. Application filed June 24, 1896. Serial No. 596,772. (No model.)
Be it known that LIVALTER II. KNIGHT, a citizen of the United States, residing at New Brightomin the county of Richmond and State of New York, have invented certain new and useful Improvements in Fluid-Pressure Motors, of which the followingis a specification.
My invention relates to means for automatically regulating the supply of fuel to the burners of the heaters of fluid-pressure motors.
My invention applies to the form of fluidpressure motors which exhaust into an inclosed chamber, preferably in the form of a casing inolosing the crank and working parts of the engine and provided with muifling devices which are adapted to prevent the increase of dust by retaining a moderate pressure in the inclosed chamber. I provide an automatic valve in the oil-pipe leading from the oil-reservoir to the oil-burner,which valve is automatically opened and closed by the pressure upon a diaphragm, the diaphragmchamber being in communication with the exhaust-chamber of the motor. hen the motor is performing its utmost amount of work, the pressure in the exhaust-chamber will be greatest by reason of the rapidity of exhaust into the chamber. This pressure will cause the diaphragm to hold the oil-valve open for supplying an increased amount of oil to the oil-burner of the heater. lVhen the motor is at a standstill or is performing a small amount of work, the pressure in the crank-chamber is slight and the valve will be nearly closed, shutting off the main supply of oil, but allowing a sufficient amount to keep the burner lighted.
In the accompanying drawing I have represented my invention diagrammatically, in which- A is a compressed air reservoir having throttle-valve B, controlled by the controllerrod 0.
D is the heating-coil, communicating with reservoir A through pipe E and with the cylinder F of the motor through the pipe G.
His the oil-burner of the heater, supported beneath the heating-coil D.
I is the oil-reservoir.
J is the oil-supply pipe, leading from the reservoir to the burner II and having interposed the automatic valve K. The valve K comprises a valve-clapper 7t, mounted upon a vertically-movable valve-spindle K, which is held normally nearly closed by the spiral spring K K is a diaphragm to which the upper end of the valve-stem K is attached.
L is a diaphragm-chamber communicating through pipe L with the inclosed crankchamber M of the motor.
N N are spring-pressed plates or covers supported over the restricted exl1aust-openings leading from the inclosed crank-chamber. These muli'ling-plates N serve to retain a moderate pressure within the inclosed crank-chamber.
The cylinder F is adapted to exhaust into the crank-chamber in a manner Well understood.
The operation of the device will be clear from the above.
Having thus described my inventiomwhat I claim, and desire to secure by Letters Patent, is
1. The combination of a motor having an inclosed exhaust-chamber, a fluid-reservoir, a heater, and means controlled by the pressure in the exhaustchamber for regulating the supply of fuel to the burner of the heater, substantially as set forth.
2. The combination of a fluid-motor having an inclosed exhaust-chamber, a fluid-reservoir, a heating-pipe leading from the reservoir to the motor, an 0il-burner for the heater, an oil-reservoir, and means controlled by the pressure in the exhaust-chamber of the motor for regulating the supply of oil to the burner, substantially as set forth.
3. The combination of a motor having an inclosed exhaust-chamber, a fluid-reservoir, a heating-pipe communicating between the reservoir and the motor, an oilburner, an oilreservoir, a pipe leading from the reservoir to the burner, an automatic valve interposed in said pipe and having a pressure-diaphragm, and a passage communicating between the exhaustchamber of the motor and said diaphragm, substantially as set forth.
