Patented April 24, 1906.
Application filed December 21, 1905. Serial No. 292.805.
To all whom, it Ntcty/ concern:
Be it known that I, FREDERICK M. DEMI- sEY, a citizen of the United States, residing at Vallejo, in the county of Solano and State of California, have invented certain new and useful Improvements in VVave-Motors; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to wave-motors and om` of the principal objects of the same is to accumulate the energy exerted by the waves of the sea or other body of water and utilizing said energy for compressing air, which may be stored for future use in connection with various arts, such as running electric light and power plants or to furnish compressed air to be used in steam-engines instead of steam.
Another object is to provide a simple and constantly-operated wave-motor which will operate under various conditions and which will be reliable, strong, and durable in use and which will not be liable to get out of order.
These and other objects are accomplished by means of the construction illustrated in the accompanying drawings, in which- Figure 1 is a vertical sectional view of a device made in accordance with my invention, and Fig. 2 is a diagrammatic view of a power plant established in accordance with my invention.
Referring to the drawings for a more particular description of the invention, the numoral 1 designates an anchoror weight adapted to rest upon the bottom of the ocean, bay, or other body of water at. a point some distance from the shore. This anchor may be conveniently constructed of sheet metal and provided with a chamber 2, which may be filled with rook, sand, or other heavy substance. A central chamber 3 is rovided, and at the upper wall of the centra chamber a socket 4 is formed'in any suitable manner, as by plates 5 6, secured to the body of the anchor by bolts 7. A weighted ball 8 is fitted within the socket and is provided with a shank 9 and a weight 1() at the lower end thereof. At the upper end of the ball 3 a flange 11 projects, and connected to this shank by a cross-bolt 12 is a pulley-frame 13, to which a wheel or pulley 14 is journaled. A float or buoy 15, comprising a hollow sheet-metal casing, is connected to the anchor by means of a cable I6, attached to a ring 17 on the buoy and to a ring 18 on the anchor, there being sufficient slack in the cable to permit a free movement of the buoy within certain limits.
The buoy is adapted to ride the waves and upon an upward movement to pull upon a cable 19, connected to the bottom wall of the buoy and passing around the pulley 14 and from thence to a suitable winding mechanism or motor located upon the shore at some distance from the buoy. Located upon the shore is a suitable frame or support 20, comy prisin T upright bars, and journaled within these zbars is a shaft 21. Loosely mounted upon this shaft is a winding-drum 22. At one end of the drum and fixed to said drum is a ratchet-wheel 23, and at the side of said ratchet-wheel and fixed to the shaft 21 is a wheel 24, to which a series of pawls 25 are pivotally connected. Secured to the shaft 21 is a gear-wheel 26, adapted to mesh with a pinion 27, fixed upon a crankshaft 28, journaled in the frame of the machine. Connected to the crank 29 of the crank-shaft 28 is a piston 30, adapted to reciprocate in a cylinder 31 to force air through a ipe 32 to a place of storage or use. The cab e 19 passes around a grooved pulley 33, journaled in the motor-frame, said cable extending thence up and around the drum or cylinder and forming three or four strands of the cable around sald drum, the winding being from the front toward the back, so that when there is a pull upon the cable 19 the drum or cylinder is rotated backwardly, as indicated by the arrow in Fig. 1. A cable 34, having a weight 35 secured to its lower end, is wound upon the drum or 'cylinder in a direction opposite to the winding of the cable 19.
The operation of the invention may be dcscribed as follows: When the buoy rises upon the crest of a wave, it draws upon the cable 19, Whichrotates the drum or cylinder 22 in the direction of the arrow, and the awls engage the ratchet-teeth and rotate the s aft 21. The rotation of this shaft operates the air-pump in an obvious manner and forces air through a pipe to a place of storage or use. When the buoy descends in the trough of the sea, there is a certain amount of slack in the cable 19, which is promptly taken up by means of the cable 34 and the Weight thereon, the pawls then ridin Y over the teeth on the ratchetwheel unti the buoy again ascendsupon the crest of a wave, when the winding action is repeated. It will be understood, of course, that any number of drums or cylinders may IOO IIO
be mounted upon the shaft 2 to bel used in connection with a buoy and anchor for each cylinder or drum, and in this Way a large uantit of energy may be stored. Owing to t e slac in the cable 16, the float or buoy can move out of .a vertical lane with the anchor Without interfering with the action of the cable 19, owing to the ball-and-socket arrangement and the manner of mounting the pulley.
From the foregoing it will be obvious that the Winding mechanism may be located upon a brid e over the water or a raft instead of being ocated on the shore, and it will be understood that the Word shore in the claims is intendedto cover such an arrangement and location of the parts of the device.
Various changes in the form, proportion, and the minor details of construction may be resorted to Without departing from the principle or sacrificing any of the advantages of this invention. l
Having thus described my invention, what I'claim as new, and desire to secure by Letters Patent, is-
1. In a Wave-motor, a buoy adapted to rise and fall with the waves, an anchoring device connected to the buoy bya slack cable, a driving-cable connected to the buoy and passing around a pulley mounted upon a weighted ball, and a socket for said ball on said anchor, in combination with` a winding mechanism, and means for storing the energy by the rise and fall of the buoy, substantially as described.
2. A wave-motor comprising a buoyant element, a weight or anchor, a cable connected to the buoyant element and passing around a pulley mounted upon a Weighted ball, and a socket for said ball upon the weight or anchor, in combination with a winding-drum mounted loosely upon a shaft, a ratchet mechanism secured to said shaft to be rotated around said pulley, said cable extending to a winding mechanism upon the shore, in combination With a drum mounted loosely u on a shaft, a ratchet mechanism fixed to said rum,
a cable and counterweight for takin up the slack of the first-mentioned cable, an an airpump operated by said shaft, substantially as described.
4. A wave-motor comprising a buoy, a weight or anchor, a flexible connection between said buoy and anchor, a socket formed in the upper wall of the anchor, a weighted ball adapted to move in said socket, a pulley connected to said ball, a cable connected to the buoy and extending around said pulley, said cable extending to and around a drum located upon the shore, said drum being loosely mounted upon a shaft, a ratchet mechanism iixed to said shaft at the side of said drum, a counterweight for taking up the slack of said cable, a gear-Wheel on said shaft, a crank-shaft mounted inthe frame, a pinion meshing with' said gear-wheel, and an airpump operated by said crank-shaft, substantially as described.
In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
