Definitions
- This invention relates to wave and tide powers, and has for its object to provide improved and simple means for the steady, uniform, and economical application of power derived from the oscillatory movements of one or more floats or buoys moored in position to be acted on by the rolling and tumbling motion of the water.
- the invention consists in a reversely-rotary shaft, (one or more,) actuated from a iioat or floats through suitable powertransmitting connections, combined with intermittentlyrotating shafts mounted on opposite sides of all the reversely-rotary shafts and parallel therewith, automatic clutch-gearing through which the intermittently-rotating shafts are actuated from the several reversely-rotary shafts,and a continuously-driven shaft geared with and actuated from the intermittentlyrotating shafts and from.which continuouslydriven shaft power may be taken for driving machinery, running dynarnos, air-compressors, and other mechanism, and for transmitting power generally.
- Figure l is a partial plan of a wavepower embodying my improvements.
- Fig. 2 is a part-sectional elevation of the same.
- Fig. 3 is a vertical transverse section of the apparatus at a point through one of the reverselyrotary shafts.
- Fig. 4 is a vertical transverse sectional view at the point where the motion of the intermittently-rotating shafts is transmitted to the continuously-driven shaft.
- the reference-numeral l designates a scaffolding or framework of any suitable construction erected over a sufficient depth of water to provide for an ecient utilization of wave-power through the medium of iioats or buoys 2, that are moored beneath said scaffolding in such manner as to rise and fall with the oscillatory movements of the tide and waves.
- buoys 2 may be of any suitable form and construction; but obviously they must have sufficient strength to withstand the pressures and strains to which they may be subjected.
- One -or more buoys or floats 2 may be employed, according to the power desired.
- buoys or floats 2 When employing a plurality of buoys or floats 2, they may be arranged in a series at suitable distances and be connected by cables 3, secured to said buoys on opposite sides of each at a point below its top, and also by cables 4, secured to stanchions 5, erected on the top of each buoy.
- the connected buoys are conveniently moored by means of cables 3fL and 4a, Figs. l and 2, extended from the ends of the series of buoys and in line therewith. At one end these cables 3 and 4 may lbe secured to opposite parts of a buoy at the same points as the cables 3 and 4, as shown.
- the cables 3n and 4a may be fifty feet in length, more or less, and are secured to mooring-posts 6 and stay-posts 6, placed one behind the other at a distance of, say, forty-eight feet from the nearest buoy. These mooring-posts and stay-posts may be's'uitably braced or coupled together in any preferred manner. Although only one end of the series of buoys or floats is represented in the drawings, it is to be understood that both ends of the series are moored in substantially the same manner by means such as j ust described. Each buoy or fioat 2 is also moored independently of the others by means of cables 7 and 8, Figs. l and 3, extended at right angles to the series of buoys.
- These cables may also be fifty feet in length, more or less. At one end they are secured to the buoys in the manner already described with reference to the mooring-cables 3?L and 4n and at the other end they connect with mooring-posts 9 and stay-posts 9*, Fig. 1, placed one behind the other at a distance of, say, forty-eight feet from the buoy.
- the object of having the several mooring-cables of slightly-greater lengthv than the distance between the buoys and the-mooringposts is to provide for a sufficient play of the buoys to avoid undue strain and yet maintain the position of the several buoys within such limits as are best suited to a steady and uniform development of Wave-power.
- each float or buoy there are bearings 10, in which, above each float or buoy, there is mounted a reversiblyrotary I ⁇ powershaft 11, that is arranged to be reversibly rotated or alternately revolved in opposite directions by the oscillatory up-an ddown movements of the float or buoy with which said shaft is in operative connection.
- a series of reversibly-rotary shafts l1 corresponding with the number of floats or buoys, and all these shafts are in line with each other,one above each buoy,through out the series.
- a winding drum or drums 12 To each reversiblyrotary shaft 11, at apoint above the center of its actuating-buoy,there is secured a winding drum or drums 12, Figs.
- each drum 12 is connected directly with the buoy 2 by means of power-transmitting cables 13, having one end secured to the buoy, as at 14, in any suitable manner, the other end of each cable being secured to and wound on its appropriate drum.
- Each reversibly-rotary shaft 11 has also secured thereto, near each end of said shaft, a winding-drum 15, Figs. l and 2, to each of which is secured one end of a powertransmitting cable 16, Figs. 2 and 3, that indirectly connects both drums with the actuating-buoy.
- This power-transmitting cable 16 is extended beneath submerged guidesheaves 17, Figs. 2 and 3, that are supported between posts 18, which may form. part of the main scaffolding or framework.
- the two submerged sheaves 17 are each mounted in its separate rectangular frame 22, which is provided on opposite sides with vertical arms 23, having series of holes 24 there in, as shown in Fig. 2. These vertical arms 23 are confined laterally by guide-flanges 25, arranged vertically on the posts 13, between which the sheave-frame 22 is placed.
- the posts 1S may be braced by struts 26, extended to stay-posts 27, or otherwise, as desired.
- each sheave 17 While each sheave 17 is designed to be submerged, the arms 23 are of sufficient length to extend above the water, and thus a suitable pin or bolt inserted through any of the exposed holes 24 will serve to hold the sheave down to a proper depth of submersion to take up any slack in the cable 16 and maintain it in a suitably taut and operative condition with relation to the drums, sheaves, and buoy.
- the bolt o1' pin that is inserted through any of the holes 2l to hold down the sheave-frame 22 is readily accessible, being above the surface of the water, and after withdrawing such piu or bolt the sheave-frame and sheave can be readily lifted out of the water to a point above the guide-flanges 25 and be thus disengaged or removed for the purpose of making any needed repairs or for disentangling seaweed or other ioating matter that might obstruct the operation of the sheaves and cable.
- the reversibly-rotary shaft 11 will be rotated in one direction through the cables" 13 and in the other direction through the cable 16, in accord with the oscillatory or rising-and-falling movements of the float or buoy2 as acted on by thewaves and tide. It will be observed that the arrangement of the continuous cable 16 with relation to the submerged sheaves 17 and buoy-sheaves 19 2O will permit any swinging or tilting of the buoy without causing slack in either portion of said cable 16 at opposite sides of the buoy.
- the drums 12 and 15 may be spirally iiuted, as shown, and any suitable guide device 28, Figs. 2 and 3, maybe provided for laying the cables 13 in the grooves of their windingdrums.

WAVE AND TIDE POWER.
SPECIFICATION forming part of Letters Patent NO. 639,733, dated December 26, 1899. Application filed April 27, 1899. Serial No. 714,747. (No model.)
To @ZZ wiz-0m, i? may concern:
Be it known that I, CLAUDE M. JOHNSON, a citizen of the United States, residing at Lexi ington, in the county of Fayette and State of Kentucky, haveinvented new and useful Improvements in "Wave and Tide Powers, of which the following is a specification.
This invention relates to wave and tide powers, and has for its object to provide improved and simple means for the steady, uniform, and economical application of power derived from the oscillatory movements of one or more floats or buoys moored in position to be acted on by the rolling and tumbling motion of the water.
The invention consists in a reversely-rotary shaft, (one or more,) actuated from a iioat or floats through suitable powertransmitting connections, combined with intermittentlyrotating shafts mounted on opposite sides of all the reversely-rotary shafts and parallel therewith, automatic clutch-gearing through which the intermittently-rotating shafts are actuated from the several reversely-rotary shafts,and a continuously-driven shaft geared with and actuated from the intermittentlyrotating shafts and from.which continuouslydriven shaft power may be taken for driving machinery, running dynarnos, air-compressors, and other mechanism, and for transmitting power generally.
The invention further consists in features of construction and novel combinations of devices, as hereinafter described and claimed.
In the annexed drawings,illustratin g the invention, Figure l is a partial plan of a wavepower embodying my improvements. Fig. 2 is a part-sectional elevation of the same. Fig. 3 is a vertical transverse section of the apparatus at a point through one of the reverselyrotary shafts. Fig. 4 is a vertical transverse sectional view at the point where the motion of the intermittently-rotating shafts is transmitted to the continuously-driven shaft.
In the drawings the reference-numeral l designates a scaffolding or framework of any suitable construction erected over a sufficient depth of water to provide for an ecient utilization of wave-power through the medium of iioats or buoys 2, that are moored beneath said scaffolding in such manner as to rise and fall with the oscillatory movements of the tide and waves. These buoys 2 may be of any suitable form and construction; but obviously they must have sufficient strength to withstand the pressures and strains to which they may be subjected. One -or more buoys or floats 2 may be employed, according to the power desired.
When employing a plurality of buoys or floats 2, they may be arranged in a series at suitable distances and be connected by cables 3, secured to said buoys on opposite sides of each at a point below its top, and also by cables 4, secured to stanchions 5, erected on the top of each buoy. The connected buoys are conveniently moored by means of cables 3fL and 4a, Figs. l and 2, extended from the ends of the series of buoys and in line therewith. At one end these cables 3 and 4 may lbe secured to opposite parts of a buoy at the same points as the cables 3 and 4, as shown. The cables 3n and 4a may be fifty feet in length, more or less, and are secured to mooring-posts 6 and stay-posts 6, placed one behind the other at a distance of, say, forty-eight feet from the nearest buoy. These mooring-posts and stay-posts may be's'uitably braced or coupled together in any preferred manner. Although only one end of the series of buoys or floats is represented in the drawings, it is to be understood that both ends of the series are moored in substantially the same manner by means such as j ust described. Each buoy or fioat 2 is also moored independently of the others by means of cables 7 and 8, Figs. l and 3, extended at right angles to the series of buoys. These cables may also be fifty feet in length, more or less. At one end they are secured to the buoys in the manner already described with reference to the mooring-cables 3?L and 4n and at the other end they connect with mooring-posts 9 and stay-posts 9*, Fig. 1, placed one behind the other at a distance of, say, forty-eight feet from the buoy. The object of having the several mooring-cables of slightly-greater lengthv than the distance between the buoys and the-mooringposts is to provide for a sufficient play of the buoys to avoid undue strain and yet maintain the position of the several buoys within such limits as are best suited to a steady and uniform development of Wave-power.
On the top or upper part of the scaolding IOO l there are bearings 10, in which, above each float or buoy, there is mounted a reversiblyrotary I`powershaft 11, that is arranged to be reversibly rotated or alternately revolved in opposite directions by the oscillatory up-an ddown movements of the float or buoy with which said shaft is in operative connection. There will be a series of reversibly-rotary shafts l1, corresponding with the number of floats or buoys, and all these shafts are in line with each other,one above each buoy,through out the series. To each reversiblyrotary shaft 11, at apoint above the center of its actuating-buoy,there is secured a winding drum or drums 12, Figs. 1 and 2, preferablya double drum, as shown. These drums 12 are connected directly with the buoy 2 by means of power-transmitting cables 13, having one end secured to the buoy, as at 14, in any suitable manner, the other end of each cable being secured to and wound on its appropriate drum. Each reversibly-rotary shaft 11 has also secured thereto, near each end of said shaft, a winding-drum 15, Figs. l and 2, to each of which is secured one end of a powertransmitting cable 16, Figs. 2 and 3, that indirectly connects both drums with the actuating-buoy. This power-transmitting cable 16 is extended beneath submerged guidesheaves 17, Figs. 2 and 3, that are supported between posts 18, which may form. part of the main scaffolding or framework. Between the two submerged sheaves 17 the cable 16 passes over outer sheaves 19 and beneath an intermediate sheave 20, that are all mounted in suitable supports 21 on the top of the buoy. The two submerged sheaves 17 are each mounted in its separate rectangular frame 22, which is provided on opposite sides with vertical arms 23, having series of holes 24 there in, as shown in Fig. 2. These vertical arms 23 are confined laterally by guide-flanges 25, arranged vertically on the posts 13, between which the sheave-frame 22 is placed. The posts 1S may be braced by struts 26, extended to stay-posts 27, or otherwise, as desired. While each sheave 17 is designed to be submerged, the arms 23 are of sufficient length to extend above the water, and thus a suitable pin or bolt inserted through any of the exposed holes 24 will serve to hold the sheave down to a proper depth of submersion to take up any slack in the cable 16 and maintain it in a suitably taut and operative condition with relation to the drums, sheaves, and buoy. The bolt o1' pin that is inserted through any of the holes 2l to hold down the sheave-frame 22 is readily accessible, being above the surface of the water, and after withdrawing such piu or bolt the sheave-frame and sheave can be readily lifted out of the water to a point above the guide-flanges 25 and be thus disengaged or removed for the purpose of making any needed repairs or for disentangling seaweed or other ioating matter that might obstruct the operation of the sheaves and cable.
'ends of the cable 16 will unwind from the drums 15, and thus rotate the shaft 11 in the opposite direction, so as to reciprocally wind the cables 13 onto'their respective drums. Thus the reversibly-rotary shaft 11 will be rotated in one direction through the cables" 13 and in the other direction through the cable 16, in accord with the oscillatory or rising-and-falling movements of the float or buoy2 as acted on by thewaves and tide. It will be observed that the arrangement of the continuous cable 16 with relation to the submerged sheaves 17 and buoy-sheaves 19 2O will permit any swinging or tilting of the buoy without causing slack in either portion of said cable 16 at opposite sides of the buoy. The drums 12 and 15 may be spirally iiuted, as shown, and any suitable guide device 28, Figs. 2 and 3, maybe provided for laying the cables 13 in the grooves of their windingdrums.
As shown in Figs. 1 and.2, each primary and reversely-rotary power-shaft 11 carries a spur-gear 29, that is in mesh with pinions 30, which are loosely placed on secondary intermittently-rotating shafts 31, Figs. 1 and 3, that are mounted on opposite sides of the reversely-rotary shaft 11 and parallel therewith. Each intermittently-rotating shaft 31 is continuous throughout and is extended to such length as to be in position for receiving power from all the reversely-rotary shafts. To each of these shafts 31 there maybe secured ratchetwheels 32, through which said shafts are actuated by means of pawls 33, carried on opposite sides of the severalvloose pinions. Ob viously any other suitable clutch devices may be provided forautomatically clutching and unclutching the pinions 30 and shafts 31, so that said shafts 31 will be alternately and intermittently rotated, one shaft in one direction and the other in an opposite direction, as shown in Fig. 3, according to the reverselyrotary movements of the shaft 11 and gear 29 thereon. Thus when the gear 29 of any reversely-rotary shaft 1l turns in one direc- Jtion it will actuate one of the intermittentlyrotating shafts 31, but will not affect the other shaft 3l, owing to slipping of the pawl or clutch devices on one side or the other.
Each interrnittently-rotating shaft 31 may be connected at one end to an extension-shaft 31a by means of any suitable clutch-coupling 34, Fig. 1, with provisions for shifting said clutch to connect or disconnect the shafts 31 and 3l, as desired. When connected therewith, the extension 31 constitutes a part of IIO the shaft 31 and turns with it. On each shaft extension 31", or directly on the shafts 31 in case the clutches 34 should be omitted, there are Xed two ratchet-wheels 35, on opposite sides of loose pinions 36, provided with pawls 37 or other clutch devices for transmitting power to a spur-gear 3S, that is fixed to a continuously-driven shaft 39, Figs. 1 and 4. Between the gear 38 and one of the loose pinions 36 there is arranged an intermediate gear 40, so that the shaft 39 shall be driven continuously from either one shaft 3la or the other.
The continuously-driven shaft 39 is preferably made in two sections connected end to end by means of any suitable automatic clutch device 41, the parts of which are so arranged that while both sections of said shaft will normally rotate together one part of said clutch will be free to slip on the ot-her, and consequently permit the speed and uniform motion of the extended portion of said shaft 39 to be maintained by momentum of the iiywheel 42 thereonin case the speed of the portion of said shaft to which is attached the spur-gear 38 should be diminished by anyirregularity in the movements of the shafts that are more directly actuated from the floats or buoys.
As shown in Figs. 1 and 2, the extended portion of the continuously-driven shaft 39 may carry band-wheels 43 44 for attachment of belting 45 46 to `drive a dynamo 47 or an air-compressor 48 or any other machinery. The air-compressor 48 may connect by pipes 49 with a compressed-air reservoir 50, from which the compressed air may be conducted by suitable piping to any required point to be used as a source of power or for other purposes.
Although I have referred to the shafts 11 as being reversely rotary and the shafts 31 as intermittently rotating, it will be obvious that, as actuated by only a slight movement of a buoy, the connected shaft 11 may have only a slight rocking motion at times, while, as geared with and acted on by a plurality of independently-actuated shafts 11, the shafts 31 may rotate continuously, or very nearly so, at certain times, according to the number of floats or buoys included in the apparatus. I would therefore have it understood that the terms reversely rotary as applied to the shafts 11 and intermittently rotating as applied to the shafts 31 have been adopted for convenience of description and not as imposing any limitation with regard to the degree of movement imparted to these shafts.
What I claim as my invention is- 1. The combination of a reversely-rotary shaft, means for actuating said shaft from a iioat or buoy acted on by wave-power, intermittently-rotating shafts mounted parallel with said reversely-rotary shaft on opposite sides thereof, gearing connecting said shafts and comprising automatic clutch mechanism through which the intermittentlyrotating shafts are alternately actuated from the reverselyrotary shaft, and a continuouslydriven shaft geared with said intermittentlyrotating shafts and actuated therefrom alternately, substantially as described.

The combination of a reversely-rotary shaft having winding-drums secured thereon, a float or buoy, means for mooring said buoy, powertransmitting cables connecting the buoy with the drums on the reversely-rotary shaft in such manner that rise and fall of the buoy as acted on by wave-power will actuate said reversely-rotary shaft through said cables, intermittently-rotating shafts mounted parallel with said reversely-rotary shaft, gearing connecting said shafts and comprising automatic clutch mechanism through which the intermittently-rotating shafts are alternately actuated from the reversely-rotary shaft, and a continuously-driven shaft geared with and driven from said intermittently-rotating shafts, substantially as described.
