' WAVE Moron.

`\ Application filed January.3,1`1921. Serial No. 434,705.

. cipi'ocating a piston rigid with the actuating means and moving in a4 cylinder forcoinpressing airor other fluid therein.`

The, invention will be readily understood 'from the following description of the accompanying drawings, in which Figure 1 is a longitudinal section through a motor constructed in accordance withthe invention. Y.

Figs. 2 and 3 are transverse sectionsl on thev lines 2-2 and of Fig. 1.

In the form of the invention illustrated in` Figs. 1 to 3, I have shown `the wave'motor mounted in a wall 1, whichfis preferably a sea wall having waves of the ocean represented at 2 impinging against said wall.

1t will be obvious however, that the upright 1 need not be a stationary sea wall, but

might be readily formed upon a suitable iioat or the like.` j,

A. cylinder 3 is mounted 'transversely of upright 1, so as to project rearwardly from the same, and at its front end is preferably closed by an end plate f1 in alinement with the surface of upright 1, which is adjacent the water. The rear end of cylinder 3 is threaded to receive acompression chamber 5 projecting longitudinally beyond thecylinder and having the end plate (i.`

A pistou rod 7 reciprocateswithincyliin der 3, and at its rear end a piston 8` is connected to the same for reciproeatingwithin chamber 5. An. inwardly opening check valve 9 is provided in chamber 5 -for admitting air, and an outwardly opening check valve 10 is provided inend wall 6, so as to permit the passage of air compressed in chamber 5 by piston 8 from said chamber to a suitable conduit 11 extending` beyond checlr valve 10, and adapted to carry the compressed air to any suitable point of utilization. L

The front end of piston rod 7 projects through an opening in end plate li, and a` `as claimed.

`sleeve 13 is preferably received upon this end of the piston rod. The opposite end of the piston rod is slidably received through a plate 14 extending across the rear end of cylinder 3, and suitably secured thereto as by screws 15. A coil spring y16 is receivedy upon piston rod 7 with one end thereof abutw ting `against plate 14, and its opposite end abutting against the end of sleeve 13.

A transverse plate 18 is mounted upon the outer end of piston rod 7 as by the screw connection 19, `and the outer end of sleeve 13 is similarly connected to plate 18. The plate 18 is adapted to be impinged by the waves,

i and is of suitable size and shape, so that su'liicient `through the plate to the piston rod for pressure will be transmitted actuating piston 8 within air; chamber 5, so

`as to compress air and discharge the same `through conduit 11.

As the piston rod and its piston move rearwardly through the actionl of the waves against plate 18, thespring 16 is compressed, and as a consequence, when a wave recedes from plate 1S, the parts will be lreturned to ytheir original position by the action of the spring.` j, j

Various changesmay be madewithout departing from the spirit of the invention connected to the piston and extending cX- teriorly of said. cylinder, a sleeve secured to the' rod, an abutment plate secured to the rod and sleeve and arranged exteriorlyrof the cylinder, and a spring surrounding the rod and interposed between the plate and .said sleeve for normally projecting the sleeve and rod from the cylinder. 2. A wave motor comprising a cylinder. a support therefor, a cylindrical extension at one'end of the cylinder, a stationary plate between the extension and the cylinder, a piston working within said extension, valves tion, a rod extending through the plate and for adn'iitting air to the extension when the piston 'is moved in one direction and for forcing air therefrom When the piston is moved in the other direction, a rod extend* ing through said plate and connected to the piston and extending exteriorly of Said cylinder, said rodhaving intermediate its ends aJ spring engaging stop, `an abutment plate l secured to the outer endof the rod,` and e spring surrounding the rod and interposed l0
