UNITED STATES PATENT OFFICE.
JOSEPH H. HOADLEY, OF NEW YORK, N. Y.
FLUID-PRESSURE MOTOR.
SPECIFICATION forming part of Letters Patent No. 586,384, dated July 13, 1897.
Application filed May 7, 1896. serial No. 590,559. (No model.) i
'To aZZ whom it may concern:
Be it known that I, JOSEPH H. HOADLEY, a citizen of the United States, residing at New York, in the county and State of New York, have invented certain new and useful Improvements in Fluid-Pressure Motors, of which the following is a specification.
My invention relates to improvements in the reversing mechanism for fluid-pressure motors; and it consists, essentially, of oper ating the reversing mechanism by a fluidpressure-operated device under the control of the mechanism which opens and closes the throttle-valve.
My invention is particularly applicable to the link-reversing mechanism in which the reversing-link is attached to a rod extending from a piston which works in the fluidpressure cylinder communicating at its opposite ends with a fluid-pressure pipe or reservoir and a suitable exhaust. The communication between the cylinder and the reservoir and exhaust is controlled by a suitable valve attached to and operated by the handle which opens and closes the throttle-valve of the engine.
The accompanying drawing represents a sectional elevation of a fluid-pressure motor embodying my invention.
A is the engine-cylinder.
B is the piston, and C the piston-rod.
D is the sliding cross-head, to which the piston-rod O is attached and which slides in the ways E.
F is the crank-shaft, carrying the crank G, which is connected to cross-head D by the rod H. The crank Gr works in the crank-pit I.
b b are inlet and exhaust ports in the cylinder A.
K is the main supply-port, and L is the main exhaust-port.
M is the compressed-air or fluid-pressure supply-pipe.
N is the throttle-valve cylinder, communicating with air-pipe M and with the main supply-port K through the pipe 0.
P is a throttle-valve comprising the main central piston 19 and the two end pistons 19 19 all of which are maintained on the valve-rod 19 which extends through a suitable packingbox in the head of the valve-cylinder and is pivoted to the bell-crank-operating hand-lever Q.
R.is the cut-off valve, comprising, preferably, two simple D slide-valves r r, mounted upon a rod 0*.
S is the reversing-link, having its end pivoted to the rods S S carrying the eccentricyokes s s at their ends, which operate upon the eccentrics t and t, keyed to the crankshaft F.
U is the bearing-block, mounted upon the outer end of the rod r upon which the link S slides vertically.
V is the fluid-pressure reversing-cylinder, having passages 11 and 01 extending from its opposite ends to the valve-cylinder V, which is attached to or forms a continuation of the throttle-valve cylinder N.
V? is the piston, working in the cylinder V and carrying the piston-rod V which is pivotally attached to the link S. The valve-cylinder V communicates through the port 1: with the air-pipe M and with the open air through exhaust o V is a slide-valve supported in valve-cylinder V and adapted to be operated by a collar w, which is mounted upon a continuation of the valve-rod 19 which extends from the valve-cylinder N into the valve-cylinder V.
By means of the apparatus just described I am enabled to reverse the direction of the engine by the movement of the handle which opens the throttle-valve. In the intermediate position of the valves (shown in the drawing) the throttle-valve will be closed and one port of the reversing-cylinder V will be in open communication with the air-pipe while the other port will be closed, so that the reversing mechanism will not be moved. By the movement of the lever Q for opening the throttle-valve the reversing mechanism will be shifted to one position or the other for running the engine in the desired direction.
Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is
1. The combination, in a fluid-pressure en gine or motor, of suitable reversing mechanism, a fluid-pressure-operated device controlling the reversing mechanism, a fluid-supply pipe communicating with the engine or mo-- ing mechanism of the engine, a valve con trolling the admission and exhaust to and from the'fluid-cylinder, the fluid-pressuresupply pipe communicating with the engine or motor and with the reversing fluid-cylinder, the main throttle-valve of the motor, and a single controlling device constructed to operate both valves simultaneously, substan- 1 tially as set forth.
