HYDROMOTOR.

Application filed June 19, 1905, Serial No. 265,849.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, ANTON GRAF, of N ewburyport, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Hydromotors, of which the following is a specification.

My invention relates to new and useful improvements in hydromotors, and for the purposes of illustration, the device is shown in this application as embodied in a vessel for the propulsion thereof, although it is adapted to other uses as a motor.

The object of my invention is to produce a new and useful hydromotor simple in construction and efficient in operation.

My invention consists of certain novel fea tures hereinafter described and particularly pointed out in the claims.

In the accompanying drawings Which illustrate a construction embodying my invention, Figure l is a top plan view of a boat containing my improvements arranged in duplex. Fig. 2 is a detail side elevation of the hydromotor and cooperating parts, with the arrows showing the direction of the flow of the water and with certain valves opened and others closed. Fig. 3 is a similar view to Fig. 2 and showing the position of the valves and the flow of the water indicated by the arrows when the mechanism is operated to reverse the motion of the boat. Fig. 4 is a side view of the hydromotor.

Like letters of reference refer to like parts throughout the several views.

'Within the boat A, shown in dotted lines, is located the boiler B of any suitable construction and from said boiler leads a steam pipe O controlled by the valve C and forming an injector or inspirator O within the in ector chamber D. To the bottom of the chamber D is connected a pipe E which is connected by a T-joint E to the pipe E opening at E? to the water around the front of the boat. A hand-operated valve C con trols the flow of steam to the injector O Connected to the chamber D is a pipe O which is bolted or otherwise secured to the duct F 2 of the hydromotor, which consists of two exterior plates F joined together by suitable bolts as shown. Between the plates F are located a suitable drum mounted fast onthe shaft f and having the plates f 3 secured thereto and adapted to rotate therewith.

The construction of the hydromotor is not here given at length as the same will be found H carried fast on the shaft H described at large in my co-pending application filed April 2, 1906, Ser. No. 309,300.

The outlet f 7 from the hydromotor (Figs.

' D to control the passage through the same.

The pipe E is controlled by a suitable gate valve E which moves'up and down, as hereinafter described. It is connected at its up per end by a slotted connection to the lever On the said shaft supported by the brackets H H is gear segment H which'meshes with the rack H on the rod II. This rod H extends rearwardly and is provided at its rear with a suitably mounted lever H". On said rod H is mounted the bell crank J pivoted on to the .standard J and to said bell crank is connected a rod K moving in the guide J on said support J, andto said rod K is secured fast the rod K likewise secured fast to the stem of the valve F in the pipe C As shown in Fig. 2, the valves E and F are raised thereby opening the pipes E and O. In the pipe which communicates with. the pipe C through the connections previously de' scribed is a valve F, the stem of which is connected to the lever H fast on the shaft H on which is also fixed fast another seg ment H which meshes with another rack II on the rod H As shown in Fig. 2 the valve F is open, as are also the valves E and F. The valve D in the pipe D is closed.

Now with the parts described and in the positions shown in Figs. 2 and 3, the boat is propelled forward by opening the valve O which allows steam from the boiler B into the injector chamber D, which steam induces a suction of water from the front of the boat through the pipe E into the pipes E up into the injector chamber D through the pipe O past the valve F which is open, into the duct F and impacts against the blades f 3 of the wheel, thereby rotating said wheel, and passes out from the hydromotor through the outletf into the pi e F then into the pipe F past the open va ve F, into the water at the rear of the boat, as indicated by arrows Fig. 2. In this arrangement it will be seen the water is drawn by suction away from the front of the boat and forced out at the rear of the boat, the action of which is to draw the boat ahead at the bow and force it ahead at the stern.

On the shafts f (see Fig. 1) are mounted the bevel gears a which mesh with the bevel gears I) on the shafts a supported by the brackets d and on the ends of said shafts are the propellers e. The rotation of the wheel within the plates F due to the impact of the water and steam, causes a rotation of the shaft f which is communicated as above described to the propellers e.

To back the boat when standing still or to reverse the boat when going ahead, the o erator takes hold of the lever H and puffs the same rearward (see Fig. 3) which causes the rod H to move the gear segments H rearward, thereby opening the valve E connected to the lever H fast on the shaft H and to close the valve F connected to the arm H fast on the shaft H and to close the valve F by means of the bell crank lever J and connections previously described, and further to close the valve E connected to the lever H fast on the shaft H and to open the a motor, a source of fluid under pressure havvalve G connected to the lever H fast on said shaft H. The parts being moved as just described, and the valve C being open, the injector C induces suction of water from the stern through the pipe E (Fig; 3) to the joint E and up through the pipe E into the injector chamber D, through the pipe C to the joint C (the valve F being closed) down through the pipe D (the valve D being opened) to the pipe D to the joint F (valve F being closed) up through the pipe F into the hydromotor, turning the wheel to the left and up and out through the duct F to the joint 1) and down through the pipe Gr through the joint D and out through the pipe Gr discharging through the end G thereof in the front of the boat. This reversal of the propellermechanism aided by the suction at the rear of the boat and the discharge at the front of the boat moves the boat rearwardly. The course of the water and steam is indicated by the arrows in Fig. 3 in the backing or in reversing the boat for backward movement.

The valve F controls the flow of steam pressure and water to the motor in that on the forward movement of the boat, said valve F being open, steam pressure and water pass into the motor through the duct F from the pipe C while on the back or reverse movement of the boat, the valve F being closed, steam pressure and water pass down the pipe D into the pipe D up through the pipe F into the motor out through the duct F to the joint D and down through the pipe Gr and out through the pipe G.

While there is shown in Fig. 1 a hydrornotor and its connecting ducts arranged in duplex, yet it will be understood that one hy dromotor and its connecting ducts or any number of motors and their connecting ducts may be used.

I do not limit myself to the arrangement and construction'shown as the same may be varied without departing from the spirit of my invention.

Having thus described the nature of my invention and set forth a construction embodying the same, what I claim as new and desire to secure by Letters Patent of the United States is:

1. In apparatus of the character specified, a motor, a source of fluid under pressure having communications with opposite sides of said motor, a valve controlling each of said communications, a liquid supply pipe leading to said source of fluid under pressure and provided with inlets opening in opposite directions, valves controlling said inlets, and an exhaust leading from said communications.

2. In apparatus of the character specified,

ing communications with opposite sides of said motor, a valve controlling each of said communications, a liquid supply pipe leading to said source of fluid under pressure, exhaust pipes leading from said communications upon opposite sides of said motor and having outlets opening in opposite directions, and valves controlling said outlets.

3. In apparatus of the character specified, a motor, a source of fluid under pressure having communications with opposite sides of said motor, a valve controlling each of said communications, a liquid supply pipe leading to said source of fluid under pressure and provided with inlets opening in opposite directions, valves controlling said inlets, exhaust pipes leading from said communications upon opposite sides of said motor and having outlets opening in opposite directions, valves controlling said outlets, and means for operating all of said valves to open the circuit through the communication from the source of fluid under pressure, the liquid supply pipe and the exhaust pipe on one side of the motor and closing the circuit on the other side of the motor. I

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses, this fourteenth day of June A. D. 1905.

ANTON GRAF.
