To all whom it concern. I I

Be it known that I, Davin NEWTON GREEN, 2. citizen'of theUnited States, and a resident of Sunbury, in the county .of Delaware and State of Ohio, have invented an Improvement in Wave-Motors, of which the following is a'specification,

My invention is animprovement in wave motors,

v boiler iron, and has a man-hole B 'cap B through which sand B may be supplied in any suitable quantities tothe float in order to insure. the

closed by a suitable and consistsin certain novel constructions and com-' desired weight to cause the float to follow the waves binations of claimed. I

In the drawings, Figurel is a perspective view, and Fig. 2 a topplan view of an apparatus embodying my invention, the "cover for the pump chamber being parts as will be hereinafter described and down quickly in the operation of the apparatus. i

The collar H is within the float than niediately below the top wall thereof, while the collars 3 is a vertical longitudinal section of the apparatus, tom wallof the float. This is bestshownin- Fig. 8 'the cover being applied; and Fig. dis-a detail view" illustrating the swinging frame employed connection with the float, 1 g

In carrying out my invention, I provide a beam A pivoted between its ends and extending at its for-' ward 'end into 'a housing frame which incloses the float B and comprises a central frnnt post 0, side posts D, a top cross beam D extending between the posts D, a bar D extending between the front post 0 and in firm connection with the float.

operates in a socket I supported on a lower cross bar I extending below the float. The upper extension projects upwardly through an opening .1 in a top cross bar I extending abovetlie float, and at its upper end the shaft H is connected preferably by a stirrup a lower cross bars I and I, and thebars .I ,'I and I tending between the top bar and the upper end of form what for convenience of reference I term a swingrnanner as to steady theoperation 'of the float in the use of the invention. The bars I and J? are located. I

The housing frame and the intermediate frame E may be made of structural iron, and a fender G which may be of boiler iron or the like, extends in a curve around the front side of the housing frame, inforcedby ribs (3 as shown, slightly deflected at its upper edge 9, and has its ends 9 turned outwardlyas shown in Fig. 2. The purpose of this fender is tobreak the force of and. to deflect any waves that may come at a great height. q

The beam A is pivoted at A in an opening E in the intermediate frame, and has on its upper side a boss or projection A which riding against the upper wall 0" of the opening E, forms a closure above the beam, and a plate E supported on theufra'm e E below the beam,- holds a rubber block e in contact with the beam to prevent water from passing through the opening E below the beam as the latter rocks.

it will be noticed extend at the sides of the housing frame while the bar I? is midway between the sid'es of the said frame and below the front arm of the rocking beam A. I prefer to connect the bars 1 and J? near their swinging ends by the side links I extending and J 2 are provided with may be in the form of balls antiiriction devices which the operation of the apparatus as the float rises and falls under t-he influence of waves approaching at an angle.

From the construction shown it will be noticed that the float is supported so axis to which end the projectingor extending ends of its shaft H form trunnions, the lower one turning inthc ball socket and the upper one nection vith the stirrup a as best shown in Fig. 3. This construction permits the flout to turn ircely and avoids any straining action that might result from a rigid (7011- nection of the float with the into the chamber F, but should any water pass through the opening E in spite of the precautions described, it will enter alaterally extending gutter E in the and discharge'at thesidc of the and lower sides of the float as before described. ing check valve f In rear of the intermediate to discharge from from Fig. 2 of the being provided to permit the water I the gutter E as will be understood drawing.

H and H are respectively above and below the, hotwith the front end of the beam. The upper and I as shown and which operate against'the inner faces of the side posts D and ease it may turn freely on a vertical beam and the swinging: 1 frame having the side bars connected with theuppcr I as.

and the described construction tends to hold the shaft 7 .The lower extension of the shaft H is provided with a. ball H v which located g on opposite sides of the float and on their outer sides near their swinging ends, the bars I? turning in its swivel conchamber F having the water-tight front wall E. In

- wave action in raising connected with the rear end of the beam A and operating to steady the motion of the beam and to aid the the float in the operation of the apparatus. This weight K is preferably in the form of a strong box of boiler iron-or the like, which may be filled with sand or other suitable weight supplied through a handheld K so it may be adjusted or varied as desired. I also provide a pump L which may be of any suitable form adapted for pumping either .air or water and connected with the rear arm of the beam A, so it will be operated thereby in a manner well understood by those skilled in the art.

In operation the apparatus is in any suitable manner on either a sand or rock shore, suilicicntly iar out into the ater to secure the desired operation of the waves chdred, the float will be caused to rise and fall undek the influence of the waves, being balanced in a measure by the counterbalancing weight K, which is directly applied to the beam and the beam is also arranged to directly operate the pump as before described.

As best shown in Figs. 1 and 3, a cover or root M is provided over the pump chamber to prevent the waves from dashing therein when the water is high.

An opening i is provided leading from the socket l to permit the escape of any sand that may get in the socket.

It will be noticed that the tender G, as before suggested, is designed to break and deflect any waves that come at a great height. This deflector also operates to reinforce and strengthen the whole housing frame, said fender extending from one side of the intermediate frame to the other side around the front of the housing frame and being reinforced by ribs G The chamber F for the counterbalancing.weight K andthe pump L is water-tightat the bottom and on all four sides.

The float B is designed to receive waves from three points, that is to say, from the trout and both sides, and

I when the waves are very high and raise the float to its extreme height, the countcrbalancing onthe bottom-of the chamber F.

weight will rest and the float being heavier than water, will not. be inclined to rise any higher, all unnecessary strain the walking beam,

pump.
