A Jr., a citizen of the United States, residing at F ruitvale, county of Alameda, State of California, have invented certain newand useful Improvements in VVave-Motors, of which the following is a specification.

My inventionl relate/sto means by which the tipping' or rocking motion produced on a float, boat, or ship, by the action of the waves, is converted into rotary motion; it w-ilzlibe more exactly understood by reference to the accompanying drawings, in Which- Figure 1 is a vertical section of my machine on line fr-m of Fig. 2. Fig. 2 is a gian: view of the mechanism., `the deck of the oat being broken away- Fig. 3 isa detail view of knuckle-joint. Figui is a section of knuckle-joint online e-z o F ig. Fig. 5 isaI section 4and plan on line .fr-a2 of Fig. 4i. F ig. 6 is ai detaili of the governor and byepass valve connections.

My invention consists of a iioat, or boat, as 1,. on which'y is universally pivotedi, at 8, the hanging lever or pendulum 2 which hangs through an opening in the bottom of the float to any desired depths, and carries on its lower end; the cross-arms or blades 3, the iiunction of which is Jto-hold the pendulum still, or approximately so,as the float is rocked by the wavesi This is done by reason @if the largey vertical surfaces presented to the water iny all horizontal directions by the blades 3. The upper and lower edges of the cross aire sharp or knife-like, and ofii'er veryl little' resistance to the rising and falling of the float.

'.Iihe'upper end of the pendulum above the fulcruni 8- is slidable loose' in a sleeve 4 which forms part of a universal knucklejoint. rEhe sleeve is pivoted in a ring 5 which i-n turn is pivoted at right angles to4 the sleeve pivots to the outside 'ring 6, through which are aseries of holes Z (Fig. 3) for'the reception of the pins by which the pump pitmen 9 are connected up 'to thel pendulum. There are four of these holes 7 1n= the present instance, but their ,number 'will vary with; the numberlopumps used in the motor. -The parts 4:-5-6 constitute my universal*knuckle-joint or connections 'bet-Ween the' pendulum andv the pumpi pitmen.. l

The universal .Eulcrum'8 forv the pendulum or lever comprises a sleeve immovably keyed or bolted to the pendulum, and which. sleeve is pivoted in a ring 8 similar to ring 5,.A and ring 5 being pivoted at right angles to the sleeve pivots in the frame of the' float. Thus it is seen that the pendulum has ai universal fulcrum accommodating the pendulum to the tossing and tipping of the float inany and all directions.

The pitmen 9 are connected to. pistonsnol plungers within the respective pump cylin ders 13 radially disposed around the u per end of the pendulum. Thechambers ov the cylinders behind the pistons are connected to a common source of fluidv supply contained in a conduit 17, and they each. discharge into a common outlet or exhaust pipe 18, leading to a three-cylinder engine 19, from .whose exhaust the duid is again led baclr through pipes 20--20a to reservoir 17 the top cylinder of the engine exhausting through pipe 20 to 17. The intake and outlet of the engineY are

throughvalves

22 and 23 opened at the proper intervals by connectingrods to an eccentric on the engine shaft, in a manner well known in the art.. The intake of each pump is through a respective valve 241, and outlet 'through 25; these valves are automatic 1n action.

I have shown the motor in this instance as used in drivin-g a-multipolar dynamo-26fnom which the electric current generatedmay be taken ashore through a cable and used ais desired. The speed of such a dynamo should be high, and 'as nearly constant as ossible for the reason that the engine cyliin ers and the inlet and exhaust pipes and'A ports are all of about the same diameter, and, as the waves are slow in movement, the volume of the. en-

ine cylinders is very much less than that of t e pumps, which will have the eect of causing many turns of the engine at each slight movement 01:' the pump plungers.. l A by-pass or shunt is provided at 27?, closed by stop-cock 28, acted: on by the' ball governor 29, which receives its motion throu h any suitable connect-ions, as 29, .from tie engine'. shait. The governor isset so' that the slowest, or least practical! movement of the plungers will run. the dynamo at its norable connections, representedvat, opening said stepfcockaindf shunting. ai portion of* the Huid through pipe 27 to reservoir. 17, thus keeping the speed of the dynamo constant. As shown in Fig. 6, the connections 30 com prise a slotted arm rigid with the governor sleeve and pivotally connected with the stem of valve 28.

ln usin my device as thus constructed, l

l prefer to ll reservoir 17 with oil, which may that no matter in which direction the tloatv roclrs or tips under the constant motion of the Wares, the cross-arms will 'operate to maintain the pendulum approximately perpendicular, and to anchor it against the relative motion of the' float, so that the float is in the nature of a universally fulcrumed le ver and acting through the universal joint vconnection with the pumps to keep one or more of the pumps continuously in operation to supply fluit pressure to the engine.

'Having thus described my invention, what l claim and desire to secure by Letters Patent is 1 l. lin a Wave motor, the combination of a float or buoyant body, a pendulum uL crumed 'thereon to swing in all directions, and mechanism on the float connected to the pendulum by which the relative movements of the vfloat and pendulum with respect to one another are 'translated into rotary motion, said mechanism comprising an engine and a part operated thereby.
