1385865 Fishing device J B PENA 27 Feb 1973 [28 Feb 1972] 9500/73 Heading A1A A power driven float for carrying two sets of fishing gear from the shore includes a clockwork device to release the gear from spring loaded tubes and also to turn off the engine. The float is recovered by a line attached to the stern. The gear is packed in cylinders 4 attached to springs within projector tubes 42 mounted across the float at the rear and each cylinder is held in the loaded condition by a rocker arm and pawl. The clockwork device 2 has a shaft 6 driven by clockspring 8 with the unwind speed limited by the pinion meshing with gearwheel 5. On release, the shaft rotates the cam 17 whose face releases in turn each of the pawls to allow the fishing gear to be ejected. The shaft is then accelerated over the sector 7 of the gearwheel 5 with missing teeth until finger 9 rocks arm 10 to rotate shaft 11 and cam 66. This permits the spring loaded fingers 67 to rotate and to close the rotary valves 64 attached thereto, thereby closing off the inlet and exhaust connections and stopping the engine. The cam 17 has a pivotted blade 27 with a ramp on the underside which allows it to ride over the pawls 18 against leaf spring 41 when the clockspring is being wound with key 13. The propeller has vanes each of which is free to move into the working position by reaction with the water when driven but is spring loaded into a plane containing the axis of propeller rotation to minimise the reverse towing force during recovery. The engine 12 is supported in a cradle for ease of removal and is accessible past hinged cover 61. Also hinged along the same axis are the inlet and exhaust tubes 55 which are held in the raised position by spring 59 but can be lowered after releasing the spring at 60. An elbow 57 at the end of the inlet tube can be rotated away from the direction of the wind.
