SPECIFICATION formig part of Letters Patent No. 590,072, dated September 14, 18197.

Application filed October 8, 1896. Serial No. soezzo. (No model.) V

i Ta albwwm it may concerns Be it known that I, ORRIN W. PARKER, a citizen of the United States, residing at Oakland, countyof Alameda, State of California, have inventd an Improvement in Wave- Power Pumps; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to an apparatus which is especially designed for utilizing the constant motion of the waves and storing up power generated thereby.

It consists, essentially, of a fioat resting npon the surface of the water at a sufficient distance from the land, a frame extending from the float to a suitable point, where it is fulcrumed, and connections-between the frame and a series of pumps by which the pumps are actuated from the float so as to continually throw water into an elevated receptacle or reservoir, and in connection with this certain means for adjusting to suit the high tide or the throw of the stroke to be given the punps. i

Referring to the accompanying drawings, Figure l is a plan View of my deviee. Fig. 2 is an elevation of thesame. Fig. 3 is a detail View of the means forregulating the pump-stroke.

In the Construction of my apparatus I employ a float A of any suitable size, form, or Construction, the requirements of such fioat being considerable bu oyancy and adaptability to be readily moved by the rise and fall of the waves. This fioat has a horizontal frame B, one end of which is Secured to the fioat and the other extends inwardly to the land or point of support, where by means of journals at C this frame is supported so that they move easily with the float' Two other frames D eXtend from the outer upper part of the float, converging therefrcm to a point at a considerable height above the shaft on which the horizontal frame turns. All these frames are preferably made of a truee-pattern to give them sufficient strength to resist torsion without unduly weighing them down.

In the upper part of the frame C and at the inner end is fixed a stout pin or trunnion c, which is adapted to be engaged by notches formed in the adjacent end of a pitman F. The opposite end of this pitman connects with the upper end of 'a lever G, which lever is fulcrumed 'upon'a fra-me H, and the lower end of the lever is 'connected more or less directly with the plungers I of a series of pnmps J. These pumps are of` any suitable or desired size, and by their connections, as here shown, they work in'unison.

The ends ofthe pump-piston opposite to the connection between the plungers and the swinging lever are connected with a suctionchamber L, which in 'turn connects with a reservoir M, Conveniently Situated with relation thei-eto. a

The reservoir may be filled in various ways. If the wavesare sufficiently high, the water from the breaking waves may be led through a chute N and delivered into this reservoir, or inwardly-opening'valves or other devices may be employed to keep it supplied;

The suction-cham ber of the pumps connects directly with this reservoir with suitable inlet-valves, which allows the water to be drawn into the pump-cylinders when the plungers are drawn backward and forced out when the plungers are again moved inwardly.

A common main O receives the water from each of these pumps and conducts it to the desired point of` storage, a check-valve being provided to prevent the return of the water after it has' been forced into the main.

The pump-plungers are wthdrawn by the risin g of the fioatand are forced back to raise the water by the weight of the float* and its connections, when'the title recedes, thus operating the pump by gravity instead of the buoyancyof the fioat.

In order to regulate the length of the pitman 'and accommodate it and the connecting parts to the riseandcfall ofzthe tide, which is sometimes considerable, I have shown the pitman formed of 'a 'series of slot Channels or notches t', adaptedto 'en'gage the pin c on the top of the' waveactuated frame D, so that as the tide rises one of the notches may bedisen gaged and another one en gaged in itsplace. This is effected by means of a sliding arm Q, movable by means of a lever R, and having the upper end adapted to engagethe pitrnan and aise it whenever desired to change its position. The pitman is (also jointed centrally, as shown at f, so that if the movement of the fioat is too violent or great for the de- IOO sircd movement of the punps the joint in the the lower part of the pitman and insures the breaking of the lock-joint f. The lug g may be fixed to a slide V, movableupon the upper end of the lever G, and the pitman connection may be carried by the same slide, so as to maintain its relative position to the lu g.

The slide may be raised or lowered on the lever by a screw or other mechanism, so that the relative length from its end to the fulcrum may be varied to accommodate it to different strokes which it may be desired to give the plungers.

Stops S prevent too long a stroke of the plungers if the waves are high.

Either of the pumps may be disengaged, if desired, for the purpose of inspection or repairs without in any way interfering with the others, as each punp has its own set of Valves.

If it be desired at any time to raise the fioat out of water, I employ a frame, as shown at U, consisting of piles driven into the bottom upon each side ot' the fioat, and by means of suitable tackle connected with the frame and with the fioat the latter may be raised at will.

Having thus described my invention, What I claim as new, and desire to sec ure by Letters Patent, is-

1. The combination, of a fioat, a horizontal frame extending therefrom and having journaled supports for the inner end, a vertical frame extending above the horizontal one and gradually converging and increasing in depth from the fioat to the inner end, a pumpcylinder with a plunger working therein, a lever fulcruned between its ends, a jointed adjustable pitman between one end of said lever and the fioat-frame, said lever having its opposite end connected with the pumpplunger.

2. The combination of a fioat adapted to rise and fall by the movement of the waves, a horizontal truss-frame extending inwardly therefrom and having the inner end journaled so as to allow the fioat to rise and fall, vertically-disposed truss-franes having the outer ends connected with the fioat and m ain frame, said frames approaching each other and increasingin depth toward the inner end, pumps connected with the source of water supply and discharge, having plungers reciprocating therein, a lever connected with the pumpplungers at the lower end having the upper end connected with the upper part of the fioatactuated frame bya joint-ed pitman, whereby motion is transmitted to the pl un gers and its action thereon is limited.

3. The combination of a fioat adapted to be moved by the rise and fall of the waves, a horizontal truss-frame extending therefrom toward the land, journals about which the inner end is turnable when the fioat rises and falls, truss-frames extending from the fioat, converging and increasing in height toward the inner end, a pin or trunnion fixed at the top of said frame, a pitman having different points of connection with said pin whereby the length may be regulated, a lever with which the upper end of the pitman connects, the lower end of said lever being connected with a group of pumps whereby the plungers thereof are reciprocated, and a reservoir or source ot` supply, and a discharge with which said pumps are connected.

4. The combination of a fioat adapted to rise and fall by the movement of the waves, a truss-frame eXtending from the fioat inwardly toward the shore, horizontally-disposed j ournals about which the frame and fioat rise and fall, pu mps connected With the source of supply and discharge, plungers reciprocating therein, a lever with the lower end of which the pump-plungers are connected to work in unison, a jointed adjustable pitman having one end connected with the upper end of said lever having the opposite end adapted to engage the pin upon the fioat-moved lever and a slide and lever-arm whereby the pitman may be raised and shif ted' to change its connection with the float-frame.

5. The combination of a fioat adapted to rise and fall by the movement of the waves, a truss--franie extending from the fioat inwardly toward the shore, horizontally-disposed j ournals about which the frame and fioat rise and fall, pumps connected with a source of supply, plungers reciprocating therein, a lever with the lower end of which the pumpplungers are connected, a jointed adjustable pitman connecting the pump-actuating lever with the reciprocating float-actuated frame, a lug upon the lever adapted to contact with the pitman and break the joint at the end of the stroke, and a slide carrying the lug and the pitman connection, and adjustable to Or from the lever-fulcrum. p

In witness whereof I have hereunto set my hand.
