igaaigaoef Tall whom/t may concern."A 7 Be itlrnownthit "I, VILLLAM CLAY FOX, a citizenofthe' UnitedStates, residingat Penns Grove, in'thefcounty-of Salem'a'nd State Aof New Jersey, haveinvented certain new and usefull Improvements' in Wave'-y Mtors, of whichthe following'is aA speciication.'A "l My-invention relates to limprovementsV in wave motors,V an obj 'ect' of`l the 'invention being tofprovide a" moto1`"'ofthev ,character stated which'is supported* entirely upon 'a oat, the latter guided initsvertical Anievement withiny a" suitable casing 4so y"asf-to' ``rise and fall with the tide', `lo'uut'not materially infected by the motion of the waves. 4 i l A further object is to provide a "motori of the charactery described, in which al float movable by the waves imparts-r motion to a lever` andthe latter: to ax pluralityof air pumps so as to force air through"anv outlet p'ipe to bie utilized forfany desired power;

' A further object4 isft'o provide a wave motorl of extremely simple' cnstruction, and one; which will be 'strong and durable in use.

"W'ith' these andother yobjects in view'V the invention consists yin certain novelV features of construction andi combinations andarrangements ofpart'sl aswillb'e more fully hereinafter describedy and pointed' out in theclaims. i

In the accompanyingdrawings:

Figure 1 is a view in elevation, partly in vertical section, 'illustratingjH my improved wave motor. i

Fie.` 21S. View in Setoupn the line 2-"-2 of Fig; 1'. `f j Fig. 3 is a fragmentary view in section" on an enlarged scale on the line 3-3 of Fig. 2.

Fig. 4 is a view in longitudinal section through one of the pumps.

Fig. 5 is a view in longitudinal section showing the telescoping portions of the air outlet pipe, and

Fig. 6 is a view in elevation illustrating a modified form of motor.

Referring particularly to Figs. k1, 2, 3, 4 and 5, 1 represents a supporting float which is guided in its vertical movement by a cas ing 2. The latter may be of concrete, cement, or other composition suitably anchored in the groundl and having openings 3 in its Specetiolif Ltterslatent@ PatentedGcti-ZS, 1.9157-,- npiiicatonnieq september 14,1916. semaine, 139,915,

A table 8 issec'urdgto the upper ends of rods andsupports a rotaryplatform 9; Theplatforni' 9 and table Sare eonnected 'byan anglel ringO, the latter `secured," to thiefplatfrm` 9,- and havng'its internal anniiilariifange l'lprojegtirig below the lower faceof"talaleSiV 5 'As the Vtable i S I and ring' 10l are circular, the

y platform' 9 is permitted a' free rotarymovef menton the table,V yetsecurely supported by the table."

Inclined standards 12 are securediat their lower' ends to theplatform 9,' and their upper ends to air pump cylinders l13,` The cylinders 13 are connected byfa bar 14,

which together thexstandards 12 pro- Vides arigidmounting kfori purnp cyliners. t' I AA lever 15 is pivotally supported between its ends on ahfulcrumbloollV secured to the centerA ofplatform 9: This' lever 15.1pro 'jects through 'slots 1 7 in the standardsfll, and'as these slots are 'relatively narrow, the walls lthereofioperatefto preventlateral mo-ve'ineiit ofI the f level, but `permit 'free 'fiilcruminginovemeit "5 A lever yo'peratiirg i 'oat 18 supported on the surface of the Water 41 is provided with a standardl) pivotally connectedto' one'l end ofthe lever 15 as shown at 20 so that the movement ofthe iioat 18 causes the pivotal movement of lever 15.

Each pump cylinder 13 is provided with a piston 21, and pitmen 22 connect the pistons 2lwith the lever l5 so that the movement of the lever causes a reciprocation of the pistons in their cylinders.

Each piston 21 has a spring pressed check valve 23 which permits the entrance of air back of the piston during the downward movement of the piston.

Outlet pipes 211 connect the ends of the respective cylinders 13 with a T-coupling 25 and are provided with check valves 26 to permit thefflow of air in one direction only. A n

A vertical pipe ,27 is connected tothe T-coupling 25'a1id telescopes within a larger vertical pipe 28 to compensate forvertical movement of the .m0tor, and to prevent lealt-V age. A stuifng box 29 is provided around pipe 27 as shown clearly in Fig.

1ipe 28 is connected by an elbow an outlet pipe 3l, and conveys the air to any desired point for use. v Y

By constructing my improvedmotor as above explained, the float l, which supports the entire mechanism, rises and falls with the tide so that it always maintains the parts in proper relationship tothe water.

As the platform 9 isfree toturn on the table 8, the float IS can movearound the outside of `casing 2 in accordancerwith the tide and operate with equal efficiency in any position. Y V The telescoping pipes 27 and 28 not only permit this'rotary movement, but also compensate for various vertical movements;

In the modification shownin Fig. 6, I provide an outer casing 332 around the supportingl float 33. which is. held in vertical position by. means 4of .incline supports 34. The casing 32 is open at its lower end 'so as to admit the water thereto, Vto raise `and lower the iioat in accordance with the tide. In this modication, a plat-form 85 is rigidly secured to the vertical rods 36 so that Vthe motor has no rotary mounting as in the preferred fornn, A

YIn other respects the construction islike the preferred :.fOrm, and I have used the same reference numerals to indicate .like

parts. v n

Various slight changes may be madein the general form and arrangement of parts described without departing' from my invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall` within the spirit and scope of the appended claims.

Gordes of this patent may be obtaine'for 30 with Having fully described my invention, what I claim as new and desire to secure by Letters Patent is: i

l.' A'wave motor, comprising a vertically positioned stationary casing located in the water, extending above the surface and communicating with the water at a point below Vthe surface of the water, a plate on the jupper end of the casing having a plurality of openings therein, a supportingfioat located in the casing, a plurality of vertical rods secured to the float and projecting through the openings inthe plate, a platform supported by the'upper ends ofthe rods, a lever fulcrumed between its end on the platform, pumps operated by the lever,

and a float supported on the waterk and Y connected toone end of the lever.

2. A wave motor,fcomprising a vertically positioned stationary casing, a supporting float in the casing, rods secured to the iioat and projecting through ,theV top of thecasing, a platform on the rods, slottedV standards on theplatform, pumpsrsecuredto the standards, a lever fulcrumed on the plat.- form and projecting through the' slotted standards, said .lever operatively to the pumps', and a. float connected toone end of said lever. Y Y f 3. A wave motor, comprising a casing, afloat in the casing, a platform supported by connected i the fioat, a turn table onr the platform, pump. f

cylinders, slotted standards connecting the pump cylinders Vwith the turn table, a bar connecting the,cylindersa lever fulcrumed on the platform and Vprojecting through the slotted. standards, pistons inthe cylinders, Y
