Abstract

Abstract A boat propelled by a motorcycle. The boat propelled by a motorcycle has a portable ramp to get the motorcycle on and off. The motorcycle produces rotational energy by its driven wheel and transmits it to a pair of rollers covered by rubber or any nonslippery material. The motorcycle is fastened to the boat by two yokes which support the pedals making them like one piece without movement, except if the whole boat gets moved. Fore roller transmits the driving force to a gear which has a sprocket chain mounted and at the other end of this, has another gear which makes an axis spin that is connected to a gear box. Another shaft extends out of the gear box and makes the propeller spin to move the boat. The gear box has forward propeller direction and reverse propeller direction. The aft roller makes two pulleys spin which make two transmission bands spin and make two more pulleys spin which make two ducted fans spin, one on each side of the engine of the motorcycle and cool it off. The steerable wheel of the motorcycle is supported by a supporting yoke rotatably, so when the steering column moves, a wire that is connected to it will move four pulleys and then the rudder will move too having controllability. The fan protectors have air chest to have control direction for cooling the engine of said motorcycle.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 267 words
A boat for use in combination with an engine driven motorcycle having a driven wheel, and a steerable wheel comprising: a fore roller and an aft roller rotatably mounted on axes which extend transversely of a longitudinal axis of said boat, said rollers being mounted on a frame means which in turn is mounted on the boat, said rollers being in contact with said driven wheel of said motorcycle to transmit the driving force of said wheel to a propulsion means and a cooling means, said propulsion means comprising a gear box means drivingly connected to said fore roller and having an output shaft drivingly connected to a propeller for propelling said boat, said gear box means further comprising shift means for changing the direction of rotation of said output shaft for providing forward and reverse movement of said boat, said shift means comprising a pair of handles mounted to the boat and operably connected to said gearbox, said cooling means comprises a pair or ducted fans drivingly connected to said aft roller and mounted to said boat on respective sides of said motorcycle, and being generally aligned with said engine to effect cooling of said engine, said boat further comprising steering means, said steering means comprising a supporting yoke rotatably mounted to said boat to rotate about a generally vertical axis, said yoke engaging and supporting the steerable wheel of said motorcycle such that the steerable wheel and yoke will rotate together, said yoke being operably connected to a rudder means such that rotation of said steerable wheel and yoke causes rotational movement of said rudder.
Claim 2
Dependent Claim 267 words
A boat for use in combination with an engine driven motorcycle having a driven wheel, and a steerable wheel comprising: a fore roller and an aft roller rotatably mounted on axes which extend transversely of a longitudinal axis of said boat, said rollers being mounted on a frame means which in turn is mounted on the boat, said rollers being in contact with said driven wheel of said motorcycle to transmit the driving force of said wheel to a propulsion means and a cooling means, said propulsion means comprising a gear box means drivingly connected to said fore roller and having an output shaft drivingly connected to a propeller for propelling said boat, said gear box means further comprising shift means for changing the direction of rotation of said output shaft for providing forward and reverse movement of said boat, said shift means comprising a pair of handles mounted to the boat and operably connected to said gearbox, said cooling means comprises a pair or ducted fans drivingly connected to said aft roller and mounted to said boat on respective sides of said motorcycle, and being generally aligned with said engine to effect cooling of said engine, said boat further comprising steering means, said steering means comprising a supporting yoke rotatably mounted to said boat to rotate about a generally vertical axis, said yoke engaging and supporting the steerable wheel of said motorcycle such that the steerable wheel and yoke will rotate together, said yoke being operably connected to a rudder means such that rotation of said steerable wheel and yoke causes rotational movement of said rudder.
