Abstract
A downrigger apparatus for trolling in which an electric motor is energizable for winding and unwinding downrigger line from a reel. A rotor is driven in reduced speed synchronism with the reel and automatically actuates up and down limit switches to stop winding and unwinding rotation of the reel by the motor. The down limit switch is carried by a support adjustable along the path of movement of the rotor through a range of positions corresponding to different lengths of line unwound from the reel, with cooperating pointer and indicia means to indicate the length of the line unwound from the reel.
Claims10
Apparatus for use as a downrigger in trolling, comprising:
- a frame;
- reel means rotatable with respect to said frame for winding and unwinding a quantity of line;
- electric motor means energizable for rotating said reel;
- limit switch means having a limit switch and an actuating cam means which are relatively movable such that the actuating cam means is engageable with said limit switch for tripping same to shut off said motor means;
- first and second supports carrying said limit switch and actuating cam means, respectively, said first support being normally fixed with respect to said frame, said second support being connected for movement in proportional relation to said reel and relative to said first support;
- means actuable for adjusting the position of said limit switch with respect to said frame and thereby changing the position of said second support along its path of travel at which said limit switch and actuating cam means come into said tripping relation to shut off said motor;
- whereby to automatically stop unwinding of line from said reel means when a preset length has been unwound.

Apparatus for use as a downrigger in trolling, comprising:
- a frame and an electric motor fixedly supported on said frame;
- a shaft supported for rotation on said frame and rotatably driven by said motor;
- a reel fixed to said shaft for rotation therewith;
- a rotor rotatable with respect to said shaft and positive synchronizing, speed-reducing drive means rotatably driving said rotor with respect to said reel and having a speed-reducing ratio such that a partial revolution of said rotor corresponds to a substantially complete unwinding of line from said reel;
- down and up limit switch means normally fixed with respect to said frame in opposed relation to said rotor and means on said rotor responsive to rotor rotation for tripping said down and up limit switch means at points corresponding to at least partially unwound and substantially fully wound line-on-reel conditions, said limit switch means being electrically connected with said motor and responsive to said tripping for shutting same off;
- circumferentially adjustable support means for adjustably supporting said down limit switch means with respect to said frame, said support means opposing said rotor and being adjustable along the rotational path of said tripping means on said rotor for presetting the length of line required to be unwound from said reel in order to trip said down limit switch means.

Apparatus for use as a downrigger in trolling, comprising:
- a frame;
- reel means rotatable with respect to said frame for winding and unwinding a quantity of line;
- electric motor means energizable for rotating said reel, wherein said electric motor means has first and second winding means alternatively electrically energizable for causing forward and reverse motor rotation respectively;
- limit switch means having first and second parts relatively movable into tripping relation for shutting off said motor means;
- first and second supports carrying said first and second limit switch parts, respectively, said first support being normally fixed with respect to said frame, said second support being connected for movement in proportional relation to said reel and relative to said first support;
- means actuable for adjusting the position of one of said limit switch means parts with respect to said frame and thereby changing the position of said second support along its path of travel at which said first and second limit switch means parts come into said tripping relation to shut off said motor, whereby to automatically stop unwinding of line from said reel means when a preset length has been unwound;
- a manually actuable up-down selector switch mounted with respect to said frame and actuable to alternately connect said first and second motor winding means in series with first and second limit switches respectively, said first limit switch being a part of said limit switch means and openable to stop line unwinding rotation of said motor means, said second limit switch being a further limit switch positioned on said frame for opening by said second support when said line approaches being fully wound on said reel.
