Specification of Letters Patent.
Patented Jan. 25, 1916.
Application filed March 8, 1915. Serial No. 12,979.
To all whom it may concern;
Be it known that I, GEORGE W. SANDER- son, a citizen of the United States, residing at Long Beach, in the county of Los Angeles and State of California, have invented a certain new and useful Improvement in ave-Motors, of which the following is a specification.
My invention relates to a device for deriving power from waves, and has particular reference to a wave motor, objects of this invention being to provide a simple and effective device in which the force of each wave is successively utilized to transmit power, to the end that a continuous power transmitting motion may be had under all conditions of the tide.
These and other objects are accomplished by the device described in the subjoined specification in connection with the accompanying drawings in which,
Figure 1 is a sectional plan view showing my invention, the section being taken on line 11 Fig. 2. Fig. 2 is a side elevation, Fig. 3 is an enlarged end view, Fig. 4 is an enlarged section on lines 4-4 Figs. 3, 1, and 2, Fig. 5 is an enlarged section on lines 55 Fig.3, Fig. 6 is an enlarged plan view of the shaft operating mechanism, Fig. 7 is an enlarged section on lines 7-7 Figs. 4, 5 and 6, Fig. 8 is an enlarged side elevation, and Fig. 9 is an enlarged end elevation of Fig. 8.
My invention generally consists of a series of units disposed in the path of waves, whereby each unit will successively receive the force of or be actuated by the wave, and each unit will be moved independently to transmit power to elements operatively connected therewith.
Specifically my invention consists of a frame 1, suspended in proximity to the surface of the water and balanced from a superstructure 2, resting on cross pieces 3, which in turn are supported by series of piling 4, by weights 5 attached to the end of ropes or cables 5, running over sheaves 6 on said superstructure 2, the other end of said cables or ropes being connected to the frame 1. Said frame may be held stationary and out of contact with the waves, when advisable to prevent injury thereto by the buffeting of the waves in stormy weather, by any suitable device, such for instance as shown in Figs. 8 and 9, wherein the sheave 6 is provided with a ratchet 7 which is heldv against movement by a pawl 8, operable, by a lever 9, on a suitable support 10, to disengage same from ,the ratchet, such lever being secured in inoperative position by any suitable means, as a hook 12, engaging a pin 13, on said support 10.
The series of piling 4, referred to, severally comprise two piles 4 and 4, spaced apart, and provided with chafe-plates 14. Between the piles 4 and 4 extend transverse braces 15, which are connected with and serve to steady and guide the frame 1, when moved vertically by the tides. Hingedly mounted on each of said braces 15, and between the side strips of said frame is a float 16, having a beveled edge 17, and arranged to be moved relatively to the frame 1 by the motion of the waves, the movement of such floats 16, being limited by a chain 18, connected at one end to said floats, and at the other end to said transversebraces 15, coiled springs 19 being preferably interposed intermediate the lengths of said chains 18, to reduce the shock when the floats have been moved to the limit allowed by the chains. Each float 16, is provided with a bar 20, carrying an eye-bolt 21, to which is attached a cable or rope 22, that is wound over a spool 23, and runs over a spool 24, a weight being attached to the other end of said cable, for purposes to appear later.
The spools 23 and 24 are mounted in the ends 26 and 27, respectively, of a walking beam 28, loosely mounted on a shaft 30, trunnioned in pillow blocks 31, secured to blocks 32, or carried on said cross-pieces 3. Keyed or otherwise fixed to the shaft30, is a ratchet wheel 33, which is arranged to be operated by a pawl 34, on and when, said walking beam 28, is actuated by the fall or weight of the floats 16. In this manner the shaft 30 is revolved, the revolutions thereof being continuous with the successive operation of the floats.
The spool 23 is provided with a ratchet wheel 35, with which a pawl 36, is normally in engagement, to prevent the rotation of said spool by the cable 22, and thereby cause the walking beam 28 to be pulled down by the weight of the float. This pawl 36 is pivotally attached at one end to an elbow 37 and is held in normal suspended position preferably by a spring 36. One end of said elbow is pivotally carried in a lug 38, fixed to the walking beam 28, and the free end 37 thereof is arranged to strike against an abutment 39 on each of said cross-pieces 3, to cause the disengagement of said pawl 36 from the ratchet wheel 35. Upon the release of said pawl from said ratchet wheel, the spool 23 may turn freely and the float 16 may descend further, thereby automatically adjusting itself to tide conditions.
To cause the return of said walking beam 28, with the rise of the float and keep same in normal position, the end 27 of said walking beam is provided with a weight 40.
The device as hereinbefore described, comprises as many shaft operating units as there are floats, and each being identical in construction and operation, only one has been specifically described.
In operation, a wave will lift the floats 16 in succession, and in so doing cause the weights 25, to be lowered, over the revolving spools 23 and 24. When the wave has passed, the floats will descend, and through the cables, which are now held tight on the spools 23, that, due to the engagement of the pawls 36 with the ratchet wheels 35 thereof, are prevented from revolving. produce a movement of the walking beams 28, which,through the medium of the ratchet wheels 33, transmit motion to the shaft 30, said transmission of motion occurring successively as the floats are operated. Obviously any power producing mechanism may be connected with the shaft.
What I claim is:
1. A wave motor comprising a frame, suspended and balanced in proximity to the surface of the water, a shaft, a plurality of ratchet wheels fixed on said shaft, a plurality of walking beams having spools journaled thereon, a plurality of floats, hingedly secured at one end to said frame and having their free ends disposed in the path of the waves, said floats lying in the same horizontal plane and behind each other whereby to successively receive the impact of waves, a cable wound on one of the spools on each of said walking beams, and running over the other spool, weights on the ends of said cables, the other ends of said cables being connected with the free ends of said floats, means to'prevent said spools over which said cables are wound from turning, and means to release said means to permit said spools to turn when the tide falls below a fixed normal.
2. A wave motor comprising a frame, a guide therefor, a plurality of weighted cables to hold said frame in balanced suspension, a plurality of floats hingedly connected at one end to said frame and disposed in the path of waves to be successively operated thereby, a shaft, an oscillatory operating means for said shaft carrying spools, a cable wound on one of. the.
spools of each of said operating means and running over the other spool, said cables carrying weights and connected to the free ends of said floats, means to hold said spools over which said cables are wound against revolution, and means to release said means.
3. A wave motor comprising a guide, a frame movable therein, means to suspend said frame, means to balance said frame, a shaft, ratchet wheels thereon, a plurality of walking beams loose on said shaft having spools and provided with means for enga ing and operating said ratchet wheels in one direction, and means for operating said walking beams, comprising cables, each wound on one of the spools of each walking beam and running over the other spool and carrying a weight at one end, a plurality of floats hingedly attached to said frame, the
other end of each cable being attached to said floats, pawls to hold the spools on which the cables are'wound against revolution, and means operable by the movement of said walking beams to disengage said pawls from said spools.
In testimony whereof I have set my hand in the presence of two witnesses.
