Abstract
This invention pertains to power for a boat, comprising a vertically mounted rotary sail device generally amidship of the boat, a power transmission driven by the sail device, pulley directed cable, connecting between the power transmission and a pair of opposed side oar devices normally disposed in the water. The sail device is constructed in a manner whereby it always rotates in the same direction regardless of the wind direction, creating a condition whereby the boat may be directed on a straight course toward any point of the compass. A second, lever operated cable and pulley is provided to control the oar devices in a manner so as to reverse the operation of the oars with a resulting reversal of direction of the boat.
Claims21
A sail actuated oar device for propelling a boat comprising:
- A. a rotary sail structure rotatably mounted relative to the upper end portion of a shaft, normally, vertically mounted amidships of a boat, said rotary sail structure comprising,
- a plurality of vertically disposed, radially extending sail assemblies, fixed relative to a vertical tower means, rotatably mounted on said shaft;
- each sail assembly including sail panel means pivotal between first, generally planar, closed positions relative to an openwork frame assembly to cause a rotary movement of said rotary sail structure under the influence of wind forces directed against outside surfaces of said closed sail panel means, and second, open positions relative to said openwork frame assembly, accomplished by wind forces being directed against inside surfaces of said sail panel means, to permit an unrestricted movement of the wind forces through said openwork frame;
- B. a power transmission means fixed relative to said rotatable tower in a spaced relation below said rotary sail structure;
- C. oar means including reversible oar blade means to provide for selective forward and reverse movements of the boat;
- D. means to transmit reciprocating, back and forth movement to said oar means from said power transmission means;
- and
- E. means to selectively shift said oar blade means to accomplish the forward or reverse movements of the boat,
- wherein each openwork frame assembly comprises inner and outer, generally rectangular peripheral frames, and at least one intermediate vertical and horizontal frame member fixed relatively to each of said peripheral frames;
- said outer rectangular frame is hinged for pivotal movement relative to the outer vertical side of said innter rectangular frame, and including a radially extending rod fixed relative to the inner rectangular frame to contact and maintain said outer rectangular frame in radial alignment therewith when the wind forces are directed against said outside surfaces of said sail panel means and to permit said outer rectangular frame and associated sail panel means to be pivoted angularly in a downwind direction when the wind is directed against said inside surfaces of said sail panel means.
