To all whom it may concern.-
Be it known that 1', GEORGE MoNo LYNCH, acitizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Wave-Motors, of which the following is a specification. I
This invention relates particularly to that class of wave-motors in which air is compressed by a pump whose operation is dependent upon the difference in buoyancy of twofioating vessels, particularly air-tanks, one of which is partially submerged or rendered less buoyant by the admission of ballast-water thereinto and the other of which contains air only and which is consequently highly buoyant.
The object of the invention is to produce a device of the kind stated characterized by improvement in construction and operation, as
will more fully hereinafter appear. I
In the accompanying drawings, Figures 1 and 2 are side elevations of the apparatus. Fig. 3 is a top plan view, and Fig. 4 is a vertical section on the line 4 4 of Fig. 2.
Referring specifically to the drawings, the partially-submerged or less buoyant vessel consists of a cradle or supporting-buoy cornprising a hollow air and water tight base 6,
with a central well therebetween. Upon opposite sides of this base are erected hollow drums or domes 7, to one of which the air is supplied from a pump and from the other of which air is delivered through a valve at 8. At 9 is a safety-valve. cate with each other through the base, and the drums and the upper portion of the base form a reservoir in which the compressed air is stored. The base has a sea-valve 10 for the purpose of admitting water-ballast to regulate the level of the immersion, and consequently the buoyancy of the base.
Upon a crown-brace 11, extending" across between the tops of the drums 7, is supported a pump-cylinder 12, from the upper end of which a delivery-pipe 13 extends to the receivingdrum 7 This pipe contains a checkvalve 14. The pump-cylinder receives the pump-piston 15, which contains the inletvalves 16. The lower end of the pump-cylin- The drums communider, or rather the crown-brace on which it is supported, has openings 17 to let in air to the inlet-valve of the piston. p
The piston-rod 18 is fixed at its lower end to the top of a water-tight buoy or drum 19, which reciprocates vertically in the pit or well between the drums and the sides of the base on guide-rods 20, fixed to the cradle or supporting-buoy at each corner or quarter thereof. Within the drum 19 are angular braces 18, which support the piston-rod, and on the piston-rod is a spiral spring 18", which serves to cushion or prevent any excess of stroke at the extreme liftot' the piston by compression against the brace 11. The cradle or supporting-buoy is also equipped with two guide-rods 21, one on each side, for the anchor-chains, (indicated at 22.) Each guide-rod extends across the entire width of the base and the anchor-chains are fastened thereto by sliding rings, so that the handling of the chains and anchors is facilitated and'the possibility of the hawsers fouling is prevented, while always permitting the buoy to lay head-on to the wind, since the .chains will slide from one end to the other and also permit the motor to swing laterally, according to the direction of the Wind.
In operation the machine is placed on the water and anchored and the sea-valve is opened, and the outer or cradle buoy is allowed to settle in the water until the inner or pump buoy isafloat with a safe cushion of Water between it and the lower angles of the guide-rod. The sea-valve is then closed. This establishes a difference of buoyancy between the cradle-buoy and the pump-buoy, and then each passing wave will temporarily submerge the cradle-buoy, while the pumpbuoy, owing to its greater buoyancy caused by its lack of ballast, will rise on the crest of each wave as itpassesand sink to the hollow again when the Wave has passed. This produces the reciprocation of the piston in the cylinder and causes the compression of air which is stored in the tanks to be utilized as desired.
A wave-motor of much eificiency is thus produced,and it is noticeable that it is free from objectionable gearing of all kinds.
It is readprevent the inlet of water or foreign matter.
hat I claim as new, and desire to secure by Letters Patent, is
1. In a wave-motor, in combination, a less buoyont vessel having an air-resermir therein and a pump-cylinder thereon connected to the reservoir, and a more buoyant vessel supported and guided on the former vessel and having a pump-piston fitting the cylinder.
2. The combination with the less buoyant vessel having a well and guides therein, of a more buoyant vessel reciprocable in the well onthe guides, and a pump the relative parts of which are carried by the respective vessels.
3. The float for a wave-motor, having a pair of hawser-rods fixed to and extending across the under side of opposite ends thereof, and an anchorhawser having a sliding connection with each rod.
4:. In a wave-motor, the combination with a partially-submerged base-float having a central well and air-reservoirs mounted upon 0pposite sides of the base, of a pump-cylinder connected to the reservoirs, and supported thereon over the well, and a pump-float reciprocable in the well and having a piston working in the cylinder.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
