HYDROMOTOR.

Specification of Letters Patent.

Patented June 16, 1908.

Application filed April 2, 1906. Serial No. 309,300.

T 0 all whom it may concern:

Be it known that I, ANTON GRAF, of New bury, 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 imprlovements in the propulsion of boats or vesse s.

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

In the accompanying drawings which illustrate a construction embodying my invention,'Figure 1 is a top plan view of a boat containing my improvements arranged in duplex. Fig. 2 is a side elevation of the same. Fig. 3 is a detail side elevation of the l'iydromotor and cooperating parts, with the arrows showing the direction of the flow of the water and with certain valves opened and others closed. Fig. 4 is a similar view to Fig. 3 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. F ig. 5-is a detailed side view of one of the valves with the mechanism for operating the same to open and close it. Fig. 6 is a side view of the hydromotor. Fig. 7 is a transverse vertical central section through the hydromotor on the line YY (Fig. 6) looking in the direction of the arrow with parts in full lines. Fig. 8 is a longitudinal sectional view on the line X X Fig. 6 looking in the direction of the arrow and with the parts in full lines. Figs. 9 and 10 are respectively side and perspective views of the wheel hereinafter described.

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

ithin the boat A, shown in dotted lines, is located a boiler B, of any suitable construction and from said boiler leads a steam pipe C controlled by the valve O and forming an injector or inspirator O within the injector chamber D. To the bottom of the chamber D is connected a pipe E which is connected by aT joint to the pipe E opening at E to the water around the front of the boat. Hand operated valve O controls 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 of the hydromotor, which. consists of two exterior plates F joined together by suitable bolts as shown. At the center these plates have each an inwardly turned circular flange f (see Figs. 7 and 8) and passing through these flanges is the shaft f having bearings and f extending outwardly from the flanges f and on said bearings are screw threaded suitable stuffing boxes f Mounted fast on said shaft f is .a spider f with blades f 2 forming the wheel of the hydro motor. on each of said blades are located four plates f capable of movement and guided in their movements by the pins f located in suitable slots in said plates Between the edges of said plates are located springs f adapted to force said plates automatically outwardly to make a closer fit within the plates F to prevent the escape of water past said blades. WVhile I have shown these adjustable plates yet in practice they may or may not be used as desired.

The inner edges of the plates f extend as shown at f beyond the spider f and over the edges of the flanges f, as shown in Figs. 7 and 8. The outlet f 7 from the hydromotor (Figs. 3, 4 and 6) connects with the pipe F which communicates by the T-joint F with the exhaust pipe F The pipe E is controlled by a suitable gate valve E which moves up and down, as hereinafter described. It is connected at its uper end by a slotted connection to the lever I carried fast on the shaft II. On the said shaft supported by the brackets II is a gear segment H which meshes with the rack H on the rod H This rod I-I 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 rodK moving in the guide J on said support J, and to said rod K is secured fast the rod K likewise secured fast to the stem of the valve F in the pipe O As shown in Fig. 3, the valves E and F" are raised thereby opening the pipes E and C In the pipe F which communicates with the pipe O through the connections previously described is a valve F the stem of which is connected to the lever II fast on the shaft H on which is also fixed another gear segment II which meshes with another rack H on the rod IF. As shown in Fig. 3, the valve F is open as are also the valves E and F.

With the parts described and in the positions shown in Figs. 2 and 3, the boat is started forward by opening the valve C which allows steam from the boiler B to pass 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 C past the valve F whichis open, into the duct F and impacts against the blades f of the wheel, thereby rotating said wheel, and passes out from the hydromotor through the outlet y into the pipe F, then into the pipe F past the open valve F, into the water at the rear of the boat, as indicated by arrows (Fig. 3). In the pipe D is the valve D, which is closed while the steam and water are passing through the pipe C to the hydro motor. The closing of this valve prevents the steam and water from passing through the pipes D and F while the valve F is open. 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 (Fig. 1) are mounted the bevel gears a which mesh with bevel gears b on the shafts 0 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 operator takes hold of the lever H and pulls the same rearward (Fig. 4) which causes the rod H to move the rear 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 I-I fast on the shaft II and to close the valve F by means of the bell crank J and connections previously described and further to close the valve E connected to the lever I'I fast on the shaft H and to open the valve G connected to the lever H fast on to 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. 41) to the point 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 open) 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 D and down through the pipe G through the joint D and out through the pipe G, discharging through the end G thereof in the front of the boat. This reversal of the propeller mechanism 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 arrows in Fig. 4 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 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 4 into the motor out through the duct F to the joint D and down through the pipe G2 and out through the pipe G.

While I have shown in Fig. 1 a hydromotor and its connecting ducts arranged in duplex, yet it will be understood that one hydromotor with its connecting ducts or any number of motors with their connecting ducts may be used.

In another application Serial No. 265,849 filed June 19, 1905, I have described and claimed the hydromotor without limiting it to a boat or vessel.
