l'GI-IARLEIS WESLEY HICKS, OF LOS ANGELES, CALIFORNIA, ASSIGNOR T0 THE SURF LIGHT AND POWER COMPANY, 0F LOS ANGELES, CALIFORNIA, A CORPORATION OF CALIFORNIA.

WAVE-MOTOR.

To all whom it may concern.'

Be it known that 1, CHARLES WESLEY Hicks, a citizen of the United States, and a resident of Los Angeles, in the county of Los Angeles and State of California, have invented a new and Improved Vave-Motor, of which the following is a full, clear, and eXact description.

A purpose of the invention is to provide a simple, durable and easily erected type of wave motor, which will be effective and reliable, and which will also be practically automatic in operation.

1t is a further purpose of the invention to construct a motor ofthe character described, wherein a pier is built out into the ocean or equivalent body of water, a desirable distance, in connection with which tracks are employed, having an inclination upward in direction of the shore, upon which tracks a motor carriage is adapted to travel. The motor carriage is provided with a drop gate operated by the motor of the carriage, and is operated upon by the breakers. 1n connection with the carriage an endless cable is employed, set in motion when the carriage is moved shoreward, being rendered inactive when the carriage descends the incline, and this cable when in operation actuates a series of pumps that force water up into a suitably placed reservoir, and the water from this reservoir is intended to operate a dynamo in a suitable power' house, which dynamo will supply power for commercial purposes, and will also supply power to the motor on the carriage.

lVhen the carriage reaches a predeter- -mined point inshore, means will be provided to energize the motor and hoist the gate, and the carriage with the gate elevated, will gravit ate down the tracks, and when its normal position is reached the power will be cut off and the gate will drop. The clutch connection between the carriage and said cable is cut off upon the return of the carriage, thus the pumps only work when the carriage is forced shoreward.

The invention consists in the novel construction and combination of parts hereinafter specifically described.

1n the drawings z-Figure 1 is a side elevation of the wave motor Fig. 2 is an outer end view thereof, Fig. 3 is a plan view of the de vice, parts being broken away; and Figs. 4

and 5 are detail side and end elevations respectively of the clutch connection between the carriage and the driving cable for the pumps.

The structure is made in two sections, A and A3, the sections being a unit, yet in operation one is practically independent of the other, and both sections have an upward inclination from out-shore to in-shore, as is shown in Fig. 1.

The pier section A is supported at its outer side by standards 10, driven into the beach A', and it may be here remarked that the normal tide level is indicated by the dotted line A2, shown best in Fig. 1. The end standards 10 are higher than the intermediate ones, and suitable ties or braces 12 are employed in connection with the said standards 10, as is shown in Fig. 1.

The outer side portion of the section A3, which section is a skeleton one, also consists of a series of standards 13 driven in the beach A and connected by braces 13a similar to the braces 12, and the end standards of the series 13 are longer than the others, being of the same length as the corresponding standards 10. An outer cross bar 14 connects the outer end standards 10 and 13, and where the two sections A and A3 connect, a third series of standards is employed, which standards are designated as 15, and the end standards of this intermediate series correspond in length to the corresponding standards of the outer series7 as is best shown in Fig. 2. The outer end standards 15 are secured to the outer cross bar 14 and the inner end standards 15 are secured to an inner cross bar lathat connects the inner end standards 10 and 13.

A flooring 16 is provided for the section A, and is laid upon suitable parallel beams attached to the standards A10 and 15, but as heretofore stated, the section A3 is a skeleton section.

1 desire it to be understood that 1 do not confine myself to the particular construction of the frame work shown and described.

A drive shaft 17 is journaled in suitable bearings at the outer end of the structure near the top, extending from side to side, as is shown in Fig. 2, and a similar shaft 18 is likewise journaled at the inner end of the structure, as is shown in Fig. 3.

Over the section A3 a driving pulley 17 a is secured upon the shaft 17, and a corresponding pulley 18n is secured upon the shaft 18,

and these pulleys 17il and 18a carry an endless cable 19.

Upper and lower tracks 22 and 23 are se- .5 cured to the inner faces of the intermediate standards 15, preferably at a point above the platform 16, as is shown in Fig. 2, and as is also shown in the same view, corresponding upper and lower tracks, 2,2a and. 23a are 1o secured to the uprights 13. The tracks have the same upward and inward inclination as the structure itself. The tracks 22 and 23,

22@ and 23, receive between them the wheels 24 of a truck or carria e B, said wheels being mounted upon suitab e axles 25,. The carriage B is propelled inshore by the action of the breakers, and upon its inward movements, imparts motion to the cable 19. This is effected by the mechanism C shown in 2o Figs. 4 and 5 or the equivalent thereof. This mechanism consists of an upright, 26, secured tothe car platform 27, having pivoted theretov upper and lower dogs 28 limited in their i l lindependent crank shafts 52, suitably journaled on said platform 16.

outward movement by spaced stops 29 and 3,0.. The cable 19 is shown as passing through an aperture in the upright 26 and between the dogs 28. When the car or car riage is. moved up they incline the dogs straighten out and bitel the cable 19, carry-` 30 lng said cable with it, but upon the descent of the carriage B the dogs, spaced apart, assumer the position shown in Fig. 4, and thereby release the cable. Springs 31 assist the dogs to biting position.

An, electric motor 32 is mounted upon the bed 27 of the carriage B, the shaft of which motor is desi nated as 33.A At the outer end of the bed o, the, carriage B. a metal frame 34 firmly fastened, which frame extends above and below the carriage and above the frame structure, as is shown in Fig. 2. The vertical members of the frame are provided with slidewaysv 35 that receive the edges of a sliding metal gate 36 which may be counterbalanced in any suitable manner, and said frame is provided with an upper cross bar 3.7.

A shaft 38 is mounted to turn in the frame 34 adjacent to. its top, and on said shaft a drum 39. and a pulley 41 are secured. A

rope or chain 40 secured to said drum and to said gate 36 whereby to raise the gate and permit it to drop to, normal osition, and a elt 42 is assed over the pul ey 41 and also over a p ley 43. on the motor shaft 33..

A post 44 is secured to the bed of the carriage, and is suitably Wired to the motor, as is shown at 45A in Fig., 3, and arod 46 issecured to the post and preferably to` the frame 3,4, and on this rod a contact-finger 47 is either stationarily or adjustably secured,

adapted for engagement with a second con.- tact-finger 48, usually attached to the upper track 2 2, as is shown'in Fig, 3.

In the operation of this portion of the device, when the gate 36 is down, the breakers striking the gate force the carriageup the ineline, causing the clutch carried thereby to grip the cable 19 and impart motion thereto, causing the shafts 17 and 18 to revolve, but when the finger 47 engages the finger 48, 70

suitably connected with any generator of electricity, a circuit is completed between the generator and the motor and the latter is immediately set in motion, consequently the shaft 38 is revolved in a direction to raise the 75 gate 36 from the water, and at such time the carriage will of its own volition, glide down the incline until .checked by the bar 14 or other stop, and at this time the clutches slide idly along the cable 19 and the gate 30 drops to its normal position.

Force pumps 49 are located in any desired number, at both ends of the section A, being shown attached to cross beams 49, and the lower ends of these pumps enter the water. Openings 50, see Fig. 3, are produced in the platform 16, one above each pump, and the iston rods 5]. ofthe pumps, are coupled to Each crank sh aft 52 is provided with an individual ulle f 53, connected by a rope or chain 54 wit pu leys 55 located on the shafts 17 and 18.

Asis snown in Fig. 3, a connecting pipe 57 is provided foreach set of pumps, and each connecting or header pipe has individual communication 56 with each pump in a series, and both header pi es 57 are connected with a conduit 58 that eads the water to a reservoir, (not shown) elevated to any der sired extent. The water in this reservoir is Y utilized to drive a generator of electricity in a power house, and the current for the motor 32, is also obtained from this source.

It will be observed that the pumps are operated only when the carriage B is moving up the incline, but since the return of the carriage is rapid, the action of the pumps is l approximately continuous. e e

I desire; it to be understood that I dov not 1,10 confine myself to the means shown and described for making and breakingy contact between the source of power and the motor, since other means may be employed and as' favorable results obtained.
