Abstract
Abstract Installed alongside the gunwale of a fishing boat, this machine automatically repeats a fixed cycle of fishing operation which comprises the steps of keeping the fishing pole tip at a fixed height from the surface of the water while waiting for a fish to bite and, upon sensing the bit of a fish at the hook, swinging up the fishing pole to hoist the fish from the sea into the air, subsequently causing the fish to come free of the hook in mid-air above the boat''s deck and fall on the deck and, with the release of tension in the line, causing the fishing pole to be immediately lowered to the original position for the next bite.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
270 words
An automatic fishing machine comprising, in combination, a switch adapted to sense the bite of a fish through a line, a suitably resilient pole having the said line held along therewith and extended downwardly from the forward tip thereof, a reversible rotary type actuator adapted to impart an upward swing to the pole, when the said switch senses the bite of a fish, while permitting the said pole to be bent by the pull exerted thereon by the fish struggling in the water and to impart a subsequent downward swing to the pole so as to jerk the fish off the hook, when there occurs a sharp decline in the force of said pull as a result of the fish having been pulled out of the water and sent flying at an accelerated speed which exceeds that of the upward swing of the pole by the action of the pole as it recovers it original straight state, a pole operating means disposed between the said switch and the said actuator and adapted to control the rotating speed of the actuator so as to increase the speed of the upward swing of the pole substantially as compared with the speed of the downward swing of the pole, a roll-sensing arm for detecting the rolling of the ship by means of a weight, and a means cooperating with the said roll-sensing arm for compensating for changes in the height of the pole above the water surface in proportion to the degree of rolling of the ship as the pole is held outwardly from the ship while waiting for a fish to bite.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
35 words
An automatic fishing machine according to claim 1, wherein the actuator is provided on a table rocked controllably by the roll-sensing arm in proportion to the degree of the rolling of the ship detected thereby.
Claim 4
Dependent Claim
33 words
An automatic fishing machine according to claim 1, wherein the actuator has a rotary shaft angularly rotated in proportion to the degree of the rolling of the ship detected by the roll-sensing arm.
