MOTOR.

SPECIFICATION forming part of Letters Patent No.-e03,173, dated April 26, 1898 Application filed August 9, 1897.

T0 at whom it may concern:

Be it known'that I, HENRY CLAY,'a citizen of the United States, residing at Fernwood, in the county of Delaware, State of Pennsylvania, have invented a new anduseful Improvement'in Motors, which improvement is fully set forth in the following specification and accompanying drawings.

My invention consists of a novel assemblage of mechanism whereby I am enabled toconvert a maximum speed with a minimum power into a maximum power with a minimum speed, the novel features of the invention being hereinafter-fully set forth, and

particularly pointed out in the claims.

Figure 1 represents a diagrammatic plan view of a motor embodying my invention. Fig. 2 represents a horizontal sectional view through the upper'portion of Fig. 1, showing the relation of the cylinders, valves, ports,-

sponding parts'in the several figures.

Referring to the drawings, A designates the main shaft of an electric or other high-speed.

motor or other initial source of power, the same having a worm B mounted thereon, which is adapted tomesh with the gear 0, the gear'beingisecured to the shaft D, which rotates in suitable bearings.

E designates a-series 0f eccentrics or cams which are mounted on the shaft D, the work-- ing faces of which cams engage the adjacent yokes F, the 'endsG of which are attached to the plungers or pistons H,- which are caused to reciprocate in their cylinders J, there betion of one setjwill suffice for all, reference being therefore had to the left of Figs. 1 and 3.

- K designates a pipe leading from the end Serial No. 647,517. (No model.)

of the cylinder J to the compartment S of thevalve-chest L.

M designates a suction-pipe for each of the valve-chests, the same being connected with the pipe N, which communicates with the reservoir P, which is filled with glycerin, oil, or other suitable fluid.

Q designates the suction-chamber of the valve-chest L, the same having'a port leading therefrom into the compartmentS, said port being controlled by a check-valve R, which in the present instance seats downwardly, as indicated at the left of Fig. 3.

U designates the discharge-chamber of the valve-chest L, the same having a port leading thereto from the compartment S, said port being controlled by the downwardlyseating check-valve T.

V designates the discharge-pipes, which lead from each of the discharge-chambers U, thev same being connected and finally discharging into the pipe W, which leads to the reversing-valve X,said valve consisting of a casing X, in'which the plug X is' rotatably mounted, said plug being-held in position by the ring X3 and having the passage X extending therethrough, by means of which communicationis had with the pipe Y, which is connected with the pipe Z, which latter leads to; the points A B. The valve-plug X has aport X passing therethrough at an angle to the port X and when'the'ports are in the position seen in Fig. 5 said port X communicates'with'the pipes X and X X and X designate passages or ports in the valve-plug X which are arranged substantially paralleltothe port X X designates a suitablehandl'e whereby the'valve-plug X is manipulated.

, The rotation of the shaft A, by reason of the intermediate connections, will cause the reciprocation of the plungers' or pistons '11, thereby effecting a continuous flow of liquid from the reservoir P through the pipe N to the port 0, past the neck 0 of the valve b,

.lmil

into the port D, against the piston E, contained in the cylinder F, thereby forcing said piston forward or to the right and effecting the rotation of the shaft J by means of the connecting-rod common to said piston and to the crank II of said shaft, the piston L, contained in the cylinder M, simultaneously moving to the right by reason of the connection of the connecting-rod K thereto. The piston E moves forwardly until the full stroke is made, at which point the port (1 is uncovered, into which the liquid flows against the valve b, thus forcing the same to the left and closing the passage between the ports C and D, the neck C being 110w opposite the port (Z which is thus opened. As the valve Z) moves to the left the fluid in the chamber 6 is forced through the pipe 0 around to the chamber 0, against the end of the valve 1), thus forcing the latter to the left, the port (1 being then closed and the port (Z open, since the neck b is now opposite said latter port. The piston L is now occupying a position at the extreme right of its cylinder M and is in proximity to the port N, which leads to the ports (1" and (Z at which point the bridge M allows a communication between the ports M and pipe M'flwhereby the liquid is permitted to escape from the chamber 0 to said pipe M and thence through the pipe M to the pipe M and back to the reservoir P. \Vhen the piston L moves from the position seen in Fig. 2 to the right, it forces the fluid in the chamber M through the ports N and d to the port P, the fluid being exhausted thence into the pipe P, thence to the pipe X, and, through the port of the valve X to the pipe X to the reservoir.

The operation above described takes place in the cylinders F M and a detailed description thereof is therefore deemed to be unnecessary, the fluid in the pipe 6 which serves the same function for its valve-chests as the pipe c moving back and forth alternately in the direction indicated in full and dotted arrows.

To reverse the motor, the valve-plug X is turned into the position indicated in Fig. 6, the fluid passing in at pipe TV, through the port X to and out pipe X, to the pipe P", and then to the valve-chests in the direction indicated by dotted arrows, the exhaust taking place through the pipe Y, port X and pipe X back to the reservoir.

The speed is controlled by the throttlevalves II the maximum power being obtained from the shaft J when said valve II is closed, the opening of the valve II furnishing a by-pass for a portion of the fluid passing through the pipe V, and .thus reducing the volume and pressure through the pipe Y, thereby reducing the power applied to the shaft J, from which latter it is of course understood that power may be transmitted to any desired point.

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