To all whom it may concern:

Be it known that I, LEMON L. OSBORN, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Hydraulic WVater-Motors, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to hydraulic motors, more particularly to that class of motors in which the alternate ascending and descending of floats arranged in two tanks is utilized to develop power for various purposes.

Another object of this invention is the production of a hydraulic motor, which is simple in construction, efficient in operation, and consists of a comparatively small number of parts.

A still further object of the present invention is the production of novel means for alternately opening and closing the inlet and outlet means for facilitating the operation of the motor.

With these and other objects in view this invention consists of certain novel construc tions, combinations, and arrangements of parts as will be hereinafter fully described and claimed.

In the drawings: Figure 1 1s a perspective view of my device, looking at the front end of the same. Fig. 2 is a perspective view of the rear end or outlet end of the motor. Fig. 3 is a longitudinal section taken on line 33 of Fig. 1.

Referring to the drawings by numerals, 1 designates the body of the motor, which comprises tanks 2 and 3, in which tanks are adapted to work float valves 4 and 5. Brackets 6 are formed upon the body 1, intermediate the tanks 2 and 3 and a shaft 7 is journaled therein. Beams 8 are fixedly secured to said shaft intermediate their ends and are, preferably, positioned at right angles thereto, and said beams carry at each end a journal member 9, which engages the upper ends of the connecting rods 10, which rods are secured, at their lower end, to the floats 4 and 5. Therefore, it will be obvious that as the floats 4 and 5 are raised and lowered within the tanks 2 and 3 the beams 8 will be caused to rock, thereby irnparting motion to any driving means, which Specification of Letters Patent.

may be connected to the beams 8 in any suitable manner.

An operating arm 11 is fixedly secured to the shaft 7, and a rod 12 is secured to the outer end of the arm 11 and works in an aperture 13 in the outer end 14 of the link member 15. The rod 12 is provided intermediate its ends with a washer or collar member 16, which member limits the movement of said rod within said aperture 13 and said rod 12 is also provided, at its lower end, with an enlarged head portion 17 which prevents the displacement of said rod from said link 15. It will be obvious that as the shaft 7 rotates in one direction so as to cause the outer end of the arm 11 to move downwardly the rod will readily pass through the aperture 13 of the link 15 and cause the collar 16 to come in engagement with the outer end 14 of the link 15 and as the arm continues to move, it will cause the outer end 14 to be pressed downward. On the other hand, when the outer end of the arm 11 is caused to rise upwardly, the enlarged lower end 17 will be brought into engagement with the link 15 thereby causing the end 14 of the link 15 to be raised and impart rotary movement to the shaft in the opposite direction to that previously stated.

The link 15 is keyed. to the shaft 18, and as above stated imparts rotary movement to the same through the medium of the link member 15 and the arm 11. Brackets 18 are supported upon the tanks and said brackets support journals 14 in which journals are journaled the ends of the shaft 18. A plurality of arms 19 are also keyed to the shaft 18, some of which extend in opposite directions to the other, preferably, two extending rearwardly and two outwardly. To the arms extending rearwardly are connected link rods 20, which rods are connected, at their lower ends to the outer ends of the door-locking levers 21, which levers are pivotally secured at 22 to the flange 23 secured to the body of the motor 1. The lever 21 is provided upon its under surface with a con cave notch portion 24, which is adapted to normally engage protruding ends of the shaft 25, which shaft is secured to the hinged doors 26, and normally holds said doors in a closed position. The doors 26 are hinged to the flanges 23 by means of a rod 27 which has its ends journaled in said flanges and hinge members 28 are fixedly secured to the door and said rod and thereby hingedly secure said doors to the same. The doors 26 are provided with a bulged portion 29 through which passes the shaft which is provided with outer ends 25 adapted to be engaged by the notch 24 of the locking lever 21. The arms 19, which extend upwardly are connected to the locking levers 21 in a similar manner as previously described. It will be obvious that when the shaft is rotated right-handedly the levers 21 controlling one of the doors will be raised, as shown in Fig. 2 and the levers 21 will engage the shafts of the other door and hold the same in a locked position, as also shown in Fig. 2. However, when the shaft is rotated in the opposite direction the other door will be unlocked and the door which has been previously opened will be locked in a closed position after the water has been discharged from the tank having its exit through the opening closed by said last-mentioned door. It will be obvious that as soon as the looking levers 21 are raised the force of the water contained within the tank will readily throw the doors to an open position, thereby allowing the water to flow out through the opening.

A link member 30 is also fixedly secured to the shaft 18, and said link member has a link connection 31, which is also connected to a link member 32, which is keyed to a shaft 33, which is adapted to operate the rotatable valve or inlet member hereinafter described. Brackets 34 are supported upon the sides of the body of the motor 1, and carry, at their upper ends, journals 35 in which is mounted a shaft 33. An arm 36 is fixed to the shaft 33 and is connected, at its outer end, to a link member 37, which link member 37 is connected, at its lower end to an arm 38, which arm is keyed to a shaft 39 upon which are fixedly secured the valve members 40 adapted to alternately close and open said inlet openings, as hereinafter described.

Chutes 41 are secured to the front of one end of the body of the motor 1, and direct the water into the inlet openings. The inlet openings comprise a substantially circular valve casing 42, in which is mounted the valve member 40, which is adapted to close the opening 43 formed in said valve casing 42.

One of the valve members is adapted to close the front end of the valve casing 42 and the other valve is adapted to close the rear end and it will be obvious that when the arm 38 is swung downwardly the shaft 39 will be rotated, which will cause the valve member 40 to rotate right-handedly, thereby closing the front end of one of the casings and cutting oif the flow of water therethrough, which movement will through the medium of links 30 and 31 cooperate with the shaft 18 allowing the rear door communicating with the tank 2 to open, thereby allowing the water to flow out through the same and empty the tank 2. When the valve previously stated is closed the other valve will be opened thereby, allowing the other tank 3 to be readily filled, thereby causing the float 5 to rise, and as the water is emptied out of the tank 2, cause the float 4 to lower, thereby imparting an oscillatory movement of the beams 8. \Vhen the arm 18 is swung in the opposite direc ti-on or swung upwardly the valve 44 Will rotate in the opposite direction and open, thereby allowing the water to flow therethrough and fill the tank 2, causing the float 4 to rise, and the valve 45 will close, thereby, through the medium of the link connec tions 30 and 31 opening the rear door communicating with the outlet "opening and causing the tank 3 to be emptied and the float 5 to be lowered.

From the foregoing description, it will be readily seen that in the apparatus as specified, the beams 18 will be caused to oscillate through the medium of the rising and lowering function of the floats 4 and 5. It will also be obvious that when one inlet valve is open in one tank, the outlet valve will' simultaneously be closed, and when the inlet valve is closed the outlet opening will be simultaneously opened, thereby allowing the tanks to be quickly and readily filled and emptied.

The shaft 33 has connected, at each end, the links 36 and 37 for allowing the rotation of the shaft 39 and the operation of the valves 40 and 44 to more easily take place.
