Abstract

Abstract A reel for deep trolling utilizes a coaxial electrical cable as the bait positioning line in conjunction with a shielded thermistor which is connected mechanically and electrically to the cable near its weighted end. The provision of slip rings and a simple phone jack on the reel mounting bracket enables monitoring of one or more reels by means of a single thermocline meter. The reel additionally features a positive pin lock and a convenient adjustable friction brake or drag. The length of cable payed out from the reel is conveniently measured by counting reel revolutions. Other convenience features are included.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 178 words
A deep trolling reel comprising a main mounting bracket attachable to a supporting base, a manually operable reel spool supported for rotation on said bracket, a bait positioning electrical cable connected with the reel spool and windable thereon and unwindable therefrom, a thermally sensitive resistor and weighting means electrically and mechanically coupled to said cable and adapted to be lowered into the thermocline layer of a body of water with the cable by operation of said reel spool, means for releasably attaching said resistor and weighting means to a separate fishing line, slip ring means attached to said reel spool and turning therewith, stationary electrical contact means on said main mounting bracket slidably contacting the slip ring means, said electrical cable being electriCally connected with the slip ring means, an electrical connector on said mounting bracket, conductor means electrically connecting said connector and said slip ring means, whereby said cable may be electrically coupled through the connector to a remotely located thermocline meter, and friction retarding and positive locking means for the reel spool on said mounting bracket.
Claim 2
Dependent Claim 178 words
A deep trolling reel comprising a main mounting bracket attachable to a supporting base, a manually operable reel spool supported for rotation on said bracket, a bait positioning electrical cable connected with the reel spool and windable thereon and unwindable therefrom, a thermally sensitive resistor and weighting means electrically and mechanically coupled to said cable and adapted to be lowered into the thermocline layer of a body of water with the cable by operation of said reel spool, means for releasably attaching said resistor and weighting means to a separate fishing line, slip ring means attached to said reel spool and turning therewith, stationary electrical contact means on said main mounting bracket slidably contacting the slip ring means, said electrical cable being electriCally connected with the slip ring means, an electrical connector on said mounting bracket, conductor means electrically connecting said connector and said slip ring means, whereby said cable may be electrically coupled through the connector to a remotely located thermocline meter, and friction retarding and positive locking means for the reel spool on said mounting bracket.
Claim 3
Dependent Claim 66 words
The structure of claim 1, and a mounting base for said bracket, said base having a passageway extending therethrough, a cable guide arm of resilient material including an extension engageable within said passage, means on said base to clamp the guide arm extension adjustably within said passage, and a cable guiding pulley on the leading end portion of said guide arm spaced from said reel spool.
Claim 4
Dependent Claim 87 words
The structure of claim 2, and said base comprising a first base plate attached directly to said mounting bracket, a pair of captive base mounting screws on the first base plate at diagonally opposite corners thereof, a second base plate beneath the first base plate adapted for permanent mounting on a supporting base and having four corner threaded openings, diagonally opposite pairs of said threaded openings adapted to receive said captive screws, whereby the reel may be mounted in any of four quadrants for convenience of use.
Claim 5
Dependent Claim 25 words
The structure of claim 3, and a guide arm brace underlying the guide arm and also being received adjustably within said passage of the base.
Claim 6
Dependent Claim 91 words
The structure of claim 1, and said slip ring means comprising a first slip ring on the radial disc of the reel spool and a second slip ring on the reel hub and electrically insulated therefrom, said electrical cable including a pair of conductors one of which is electrically connected to each of said slip rings, said stationary contact means comprising a pair of spring contacts one each slidably engaging said first and second slip rings, and said electrical connector including terminals and conductors connecting said terminals and said spring contacts.
Claim 7
Dependent Claim 107 words
The structure of claim 1, and said friction retarding and positive locking means comprising a friction brake lever pivoted to the main mounting bracket and having a brake shoe element thereon engageable with an annular wall of the reel spool, an adjustable spring tension drag means on the main mounting bracket having a connection with said brake lever and adjustably biasing the same toward an active retarding position relative to the reel spool, and an independently operable positive pin lock device carried by the brake lever, the radial disc portion of the reel spool having spaced openings adapted selectively to receive a locking pin of said device.
Claim 8
Dependent Claim 77 words
The structure of claim 6, and a manually operable full off and full on lever for said drag means including a rotary cam, a reciprocatory stem having a connection with the cam and shifted axially by rotation of the cam around the axis of the stem, the stem adapted to contact a part of said brake lever to activate the same, and a spring connected with said stem urging it toward said part of the brake lever.
Claim 9
Dependent Claim 20 words
The structure of claim 7, and a screw-threaded element connected with said spring to adjust the tension of the spring.
Claim 10
Dependent Claim 92 words
The structure of claim 6, and said positive pin lock device comprising a guide and support for a locking pin mounted on said brake lever, a rotary and reciprocatory pin engaging said guide and support, a spring connected with said pin and urging it toward locking engagement with any one of said spaced openings, an operating handle for said pin, and a cam face on said guide and support engaging said operating handle during rotation of the pin by the handle to retract the pin axially against the force of said spring.
Claim 11
Dependent Claim 37 words
The structure of claim 9, and detent means for said operating handle at the opposite ends of said cam face to position the operating handle in full off and full on positions in relation to said pin.
Claim 12
Dependent Claim 49 words
The structure of claim 1, and a hand crank on said reel spool prOjecting beyond one side thereof and said hand crank spaced radially from the rotational axis of the reel spool and disposed adjacent the annular surface of the spool on which said electrical cable is wound up.
Claim 13
Dependent Claim 33 words
The structure of claim 5, and said electrical connector comprising a phone jack, and an adjustable resistance element electrically connected between one terminal of the phone jack and one of said spring contacts.
