Abstract
Abstract A mechanical drive actuated by wind has propellers rotatably mounted on a vertical standard which is rotatably fastened to the deck of a ship. The rotational force of the propellers is transmitted by a series of shafts to drive the ship's screw. The vertical standard may be rotated to take full advantage of the prevailing winds.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
196 words
Apparatus for using wind to actuate the screw shaft of a ship, comprising: a vertical standard rotatably fastened to said ship; a plurality of propellers, said propellers being rotatably supported by said vertical standard, said propellers arranged on said vertical standard in tandemly mounted, oppositely disposed pairs, each said propeller supported about its outer periphery by a band, said band being circular in configuration; transmitting means to transmit the rotary motion of said propellers to said screw shaft, said transmitting means including a plurality of vertical shafts mounted coaxially within said vertical standard, means for selectively interconnecting said vertical shafts, each of said vertical shafts adapted to transmit the rotary motion of one of said pairs of oppositely disposed propellers; and adjusting means for adjusting the direction in which said propellers face, said adjusting means being adapted to controlledly rotate said vertical standard, and including crank and pinion means, gear-type teeth integral with and disposed horizontally about the periphery of the base of said vertical standard; and chain means engaging said teeth, said chain means rotatably engaging said crank and pinion, whereby rotating said chain means with said crank and pinion means rotates said vertical standard.
Claim 2
Dependent Claim
196 words
Apparatus for using wind to actuate the screw shaft of a ship, comprising: a vertical standard rotatably fastened to said ship; a plurality of propellers, said propellers being rotatably supported by said vertical standard, said propellers arranged on said vertical standard in tandemly mounted, oppositely disposed pairs, each said propeller supported about its outer periphery by a band, said band being circular in configuration; transmitting means to transmit the rotary motion of said propellers to said screw shaft, said transmitting means including a plurality of vertical shafts mounted coaxially within said vertical standard, means for selectively interconnecting said vertical shafts, each of said vertical shafts adapted to transmit the rotary motion of one of said pairs of oppositely disposed propellers; and adjusting means for adjusting the direction in which said propellers face, said adjusting means being adapted to controlledly rotate said vertical standard, and including crank and pinion means, gear-type teeth integral with and disposed horizontally about the periphery of the base of said vertical standard; and chain means engaging said teeth, said chain means rotatably engaging said crank and pinion, whereby rotating said chain means with said crank and pinion means rotates said vertical standard.
Claim 3
Dependent Claim
18 words
The apparatus as recited in claim 1, wherein said vertical shafts are completely enclosed within said vertical standard.
Claim 4
Dependent Claim
186 words
Wind driven apparatus for using wind to activate the screw shaft of a ship, comprising: a plurality of propellers, said propellers being arranged in oppositely disposed pairs; a plurality of vertical standards rotatably mounted to the deck of said ship, said pairs of propellers rotatably supported by said vertical standards, said propellers in each said pair disposed on opposite sides of one of said plurality of vertical standards; transmitting means to transmit the rotary motion of said propellers to said screw shaft, said transmitting means including a plurality of selectively interconnectable vertical shafts, with each of said vertical shafts transmitting the rotary motion of one of said pairs of propellers; and means for simultaneously adjusting the rotation of said vertical standards; wherein said adjusting means comprises crank and pinion means, gear-type teeth integral with and horizontally disposed about the periphery of the base of each of said vertical standards, and chain means simultaneously engaging said teeth on each of said vertical standards, said chain means being connected to said crank and pinion means, whereby rotation of said crank and pinion means simultaneously rotates said vertical standards.
Claim 5
Dependent Claim
186 words
Wind driven apparatus for using wind to activate the screw shaft of a ship, comprising: a plurality of propellers, said propellers being arranged in oppositely disposed pairs; a plurality of vertical standards rotatably mounted to the deck of said ship, said pairs of propellers rotatably supported by said vertical standards, said propellers in each said pair disposed on opposite sides of one of said plurality of vertical standards; transmitting means to transmit the rotary motion of said propellers to said screw shaft, said transmitting means including a plurality of selectively interconnectable vertical shafts, with each of said vertical shafts transmitting the rotary motion of one of said pairs of propellers; and means for simultaneously adjusting the rotation of said vertical standards; wherein said adjusting means comprises crank and pinion means, gear-type teeth integral with and horizontally disposed about the periphery of the base of each of said vertical standards, and chain means simultaneously engaging said teeth on each of said vertical standards, said chain means being connected to said crank and pinion means, whereby rotation of said crank and pinion means simultaneously rotates said vertical standards.
Claim 6
Dependent Claim
28 words
The apparatus as recited in claim 3, wherein each of said propellers is supported at their outer peripheries by a band, said band having a circular hoop-like configuration.
Claim 7
Dependent Claim
18 words
The apparatus as recited in claim 3, wherein said vertical shafts are completely enclosed within said vertical standards.
