Abstract

A power source for an indicator light attachable to a fishing rod comprises a casing 3 adapted for attachment to the rod and including a least one cell 4 containing metal plates 5, a removable lid 6 being provided whereby sea or river water can be added to the cell to serve as electrolyte. <IMAGE>

Description

POWER SOURCE The invention relates to a power source (1) for use with a fishing rod light (2). The light is commonly used to detect rod movement in darkness.
Fishing rod lights are well known and are powered by conventional dry cell or rechargeable battery.
According to my present invention there is provided a renewable rather than a rechargeable or replaceable battery (1), comprising of a body (3) which provides cell cavities (4) into which fit the plates of alternating dissimilar metal (5) and the electrolyte. Also comprising of a dimpled cover seal (6) which provides the plate (5) location and separation and fixing. The positive and negative plate terminals (7) protrude from the dimpled cover seal (6) to provide connections for the wires (8) to the light (2).
Electricity is produced by a flow of electrons between plates (5) of dissimilar metal and the electrolyte which fills the cells (4).
Voltage is increased by a multiplicity of cells (4) connected in series. The potential difference at the positive and negative plate terminals (7) provides the voltage for the light (2).
A variable resistor may be included in series in order to vary the brightness of the light (2) depending upon ambient in darkness levels.
Vent grooves (9) in each cell allow expulsion of water to the correct level upon fitting of the dimpled cover seal (6). The grooves also serve to allow the escape of gases produced.
A dimpled feature (10) on the underside of the cover seal (6) extending a distance down into each cell (4) of the body (3) serves to seal the unit against loss of electrolyte when the unit is in use in any orientation.
The unit is regenerated by removing the cover seal (6) and exchanging the water for new water in the cells (4). The circuit is thus regenerated with no need for conventional battery charging or replacement.

Claims (12)

  1. 5) The invention relates to a power source (1) for a light (2) and has particular reference to the power source for a fishing rod (11) light.
    Lights for use at the end of a fishing rod at night are well known, but require a conventional battery to power them and accordingly, it is an object of this invention to provide a renewable rather than a rechargeable, or replaceable battery.
    10) A power source (1) according to claim 5, characterised in that the electricity is produced by a circuit set up through the electrolyte which is ordinary impure water, and plates of dissimilar metals (5) where no pre charging is required.
    15) A power source (1) according to the above claims has a multiplicity of cells (4) in order to generate the required voltage.
    20) A power source (1) acccording to the above claims has vent grooves (9) in each cell (4) to allow expulsion of electrolyte to the correct level upon fitting on the dimpled cover seal.
    25) A power source (1) according to the above claims whose vent grooves (9) allow gases generated to escape.
    30) A power source (1) according to the above claims is regenerated by replacing the electrolyte by means of the filler cover seal (6).
    35) A power source (1) according to the above claims is used to power a light (2) at or near the end of the rod (11) by means of connecting wires (8).
    40) A power source (1) according to the above claims where a variable resistor may be used in order to achieve a variable brightness of the light (2) depending upon ambient darkness levels.
    Amendments to the claims have been filed as follows Claims: 1. An electrical power source comprising a container open at one end with a compartment for holding an electrolyte, a pair of spaced plates in the compartment, and a removable lid for closing the open end, the lid being apertured to accommodate conductors connected to the plates, and the container being provided with means for attaching it to a supporting structure.
  2. 2. An electrical power source comprising a container open at one end and having a plurality of internal compartments for holding an electrolyte, a pair of spaced plates in each compartment, electrical connections between the plates such that-a plurality of series connected electric cells is formed, between output terminals, and a removable lid for closing the compartments, the lid being apertured to accommodate the output terminals, and the container being formed with means for attaching it to a supporting structure.
  3. 3. A power source as claimed in claim 2 in which the lid is formed to accommodate the electrical connections between the plates.
  4. 4. A power source as claimed in claim 1 or 2 in which the or each compartment has a vent for discharging to atmosphere gas as generated within the compartment.
  5. 5. A power source as claimed in claim 4 in which the or each vent comprises a groove in the end face of a wall of the compartment at the open end thereof.
  6. 6. A power source as claimed in any one of the preceding claims in which the means comprise arms extending from the container.
  7. 7. A power source as claimed in any one of the preceding claims in which the plates are mounted upon the lid and are removable therewith from the container.
  8. 8. A kit of parts comprising an electrical power source as claimed in any one of the preceding claims, a light source and electrical conductors for connecting the light source to the power source.
  9. 9. A kit as claimed in claim 8 in which the light source is a light-emitting diode.
  10. 10. A fishing rod fitted with a power source as claimed in any one of the preceding claims and a light source electrically connected to the power source.
  11. 11. A power source substantially as herein described with reference to and as illustrated by the accompanying drawings.
  12. 12. A fishing rod fitted with a power source and a light source substantially as herein described with reference to and as illustrated by the accompanying drawings.
