Specification of Letters Iatent. Application filed February li 1914. Serial)? 0.816513.

Be it known that I, RICHARD A. Beans, -a citizen of the United States, residing at San Bernardino, in the county of San Bernardino and State of California, have in{ 'vent-ed certain new and useful Improve- Inents in VVave-lilotors; and I do hereby declare the following to be a full. clear, and exact description of the invention. such as 'it appertains to make and use the same. The primary object of this invention is to provide an extremely simple and practical invention is to provide in a wave motor. an oscillating cylinder. a piston operable with' in: said cylinder, a piston rod extending outwardly therefrom and having secured to its the' vaves, and novel means 'for supporting the tree end of the piston rod so that the plate willalways remain substantially at the \Vith these and other objects in view as will hecoine more apparent as the descr ptain' novel features of construction, coin- "bintiilfill and arrangement of parts as will claimed.- For a complete understanding of my invention, reference is tobe had to the following description and accompanying draw:

Figure 1 is a perspective viewof my improved wave motor parts thereof being shown in' section and Fig. 2 isa detail sectional view of one of the airtight floats.

Referring in, detail to the drawings by numerals, 5 designates, as"an entirety, :1 cylinde gmounted to oscillate between support ing'legs 6 and formed-with an intake port 8 and a discharge port 7, the former being surroundedby a nipple 9 housing a check valve. 10, and the latter being provided with acheck valve-l1 opening in a direction op,-

pipe 12 connects the nipple!) with a storage tank '13 which may be located in any dethe head 17 after it has been forced ii A piston head 14' operates withinlthe-cyl indor 5 and has connected to its outer face Patented Maylg, 1914'.

.a piston rod 15 which extends throu h a bearing 16 secured to the head 17 of the cylinder. A coil spring 18 surrounds the piston rod 15 and bears at one end against thehead l? and at its other end against-the transverse pin secured tto the. rod 15. This s 'iringdraws the piston head litoward iwardly. by the waves in a manner to be hereinafter -described.

The piston rod extends over a body of water and carries upon its 'free terminal a plate 20 against which the waves impinge as;the v roll inward and"as theyrecede. At the ends of the plate 20. inwardly extending flanges 21 are provided and to the lower edges of these flanges I secure floats 22 which hold the plate normally in-a-substan-" tially horizontal position,-so as to best receive the action of the waves. To guidethe piston rod 15 and support the lifting meehanism for the plate 20 I provide a pair of standards 23 which aredr'iven intothe earth orfjon opposite sides ofthe rod near the outer end thereof. The ,upper ends of thesestandards' are. extended outwardly in a horizontal" plane in spaced relation tofo-rm arms 24 between-which a sheave-or roller 25 journaled' on an axle 26-. A flexible connection 27 runsover the sheave or pulley-25 and under a grooved pulley 28 supported under one of the arms 24 by an angular bracket 29. The outer end of the flexibleconnection 27 is connected by flanges 30 to the end of the plate 20 as clearly shown in the drawings.

A; shaft '31'projects laterally from the upper .end of one of the standards 23 and supports a pair of pulleys 32 arid33. A lsecond shaft 34'is connected to the. IsastL-nintio d'standard 23 directly underthe shaft :31 b low the sur face of thewhter, and has jour naled theregrqoved rollers or I onza grooved roller or pulley 35 in the same vertical plane as the pulley .33. An end-less cable or other flexible member 86m ns around the pulleys 3.3,,and 34 and has fixed to one leaid thereof a float 37. This float isformed with an openint 38 through which the other lead ofthe endless ie'able'passes, so that the float when "actuated by the rise 'andftall of the tide, will"move=in a vertical plane and" I beguiddxib'y the cable. A counterbalance weight -39 is secured to the lead40 of thecable- 36, and the inner end of theeonneci v tion after being passed over the pulley 83, is athdi'ed thereto. -The connection 27 is of sucli'l ileng'th as to hold the plate 26 in the same horizontal plane as the float 37, and as this float always remains on the surface oflthe water, the late will be in proper position to receive t 'e full force of the l operation, waves impinging against t-" -i late 20, force the piston head 14 inwar 1y, causing the vvalve to open and the vdlve 11 to close,whoreby air is forced into the tank or reservoir-13a The spring 18 returns thepiston 14 to its outward position after a wave'has passedjby the plate 20, and the next wave again forces the piston head inwnrdly,'and thus it will be seen that a continnitus reoiprocatory action of the piston i between 'the plate-and rod.-

I While I "have shown and described the preferred embodiment-of my invention, it will begunderstood-that 'minor changes in construiwion', combinagion 'and arrangement of parts may be ma, e without departing from the spirit aridscope of the invention as claimed. V

Having thus described my invention, I claim a 1. In a wave motor, an oscillating cylin der, a piston arranged within said cylinder, a piston roddmeans on the end of said piston rod for receiving the impact of the waves, and means for guiding and supporting the piston rod comprising a pair of standards positioned on opposite sides of the piston rod within the water, an endless cable supported in a vertical plane by one of saidstandards, a float secured to one lead of the cable, a pulley-journaled between the, upper ends of said standards, and a flexible con nection secured to the impact receiving means and to the other lead of said cable, the connection passing around the pulley.

2. In a wave motor, the combination of an oscillatin cylinder, a piston arranged within said cy inder, a piston rod, means secured to the outer end of said piston rod for re ceiving the impact of the waves, and. guide and supporting means comprising a pair of standards arranged in the water on opposite sides of the piston rod, said standards being formed with outwardly projecting arms on their upper terminals, a sheave journaled between said arm, a pair of pulleys secured to one o ftsaid standards, an endless cable -running around said pulleys, a float secured to one lead of the cable, and a flexihle'comiection secured to the impact receiving means and to the other lead of the cable, saidconnection passing over the sheave.

3. In a wave motor, an oscillating cylinder. a piston arranged witliin= said. cylinder, a piston rod, means on the end of said piston rod to receive the impact ofthe waves, a pair of standards ah-ranged within the Water on opposite sides of the piston rod and formed on their upper terminals with outwardly extending arms, a sheave journalcd between the free terminals of said arms, a pair of shafts projecting laterally from one of said standards, a pair of pulleys secured to the upper of'said shafts, a third pulle secured to the lower of said shafts, an en less cable running around said last mentioned pulley and the corresponding pulley on the upper sl'lnft, a float secured to'one lead of said cable and having an opening through which the other lead passes, a

cmintcrbalanee weight secured to the cable on the second mentioned lead and a flexible connection secured to the ill] act receiving means and to said weight, t e connection passing over the sheave and one of the pul-' leys on the upper shaft.

In testimony whereof I afiix my signature in presence of two witnesses.
