Abstract
Two equal sized sheaves, each having a crank handle, are journaled for independent rotation. A sinker weight is supported on the loop of a control cable whose ends are attached to the respective sheaves. The control cable extends tangentially from the bottom of one sheave and the top of the other. Rotating the sheaves in the same direction transfers control line from one sheave to another without raising the sinker. Rotating the sheaves in opposite directions simultaneously or in sequence raises and lowers the sinker depending on the selected directions of rotation. A fishing tackle line which is attachable to the control cable may thereby be raised and lowered independently of the sinker weight.
Claims18
A downrigger adapted to operate a cable for selectively raising and lowering a sinker means and for selectively feeding and taking up said cable independently of substantial movement of said sinker means, comprising:
- a. first and second reversibly rotatable wheel means constructed and arranged for engaging opposite end portions of a continuous cable for suspending said sinker means translatably on a loop portion of said cable formed intermediate its ends,
- b. means for rotating said wheel means individually and jointly, rotation of said wheel means individually and jointly in first opposed directions causing said cable to be fed from one and the other of said wheel means to extend said intermediate portion of said cable between said end portions for lowering said sinker means on said loop portion, and rotation of said wheel means individually and jointly in second opposed reverse directions causing said cable to be taken up on one and the other of said wheel means for raising said sinker means on said loop portion,
- c. rotation of said first and second wheel means jointly in a selected direction causing said cable to be fed from one wheel means and to be taken up by the other wheel means for said cable to translate relative to said sinker to thereby maintain the distance of said sinker from said wheel means substantially constant.
A downrigger adapted to operate a cable for selectively raising and lowering a sinker means and for selectively feeding and taking up said cable independently of substantial movement of said sinker means, comprising:
- a. first and second reversibly rotatable wheel means arranged for rotation about the same axis, each of said wheel means having means for engaging opposite end portions of a continuous cable such that an intermediate portion of said cable may form a loop portion between said first and second wheel means for suspending said sinker means in a manner that permits said cable to translate relative to said sinker means,
- b. means for rotating said wheel means jointly and individually, and means for selectively coupling and uncoupling said first and second wheel means for enabling joint and individual rotation, respectively, of said wheel means,
- c. rotation of said wheel means jointly in the same direction causing said cable to be fed from one of said wheel means and to be taken up correspondingly by the other of said wheel means while said cable including said loop portion translates relative to said sinker means for enabling said sinker means to remain at a substantially constant distance from said wheel means,
- d. rotation of said wheel means individually in first opposite directions simultaneously and sequentially causing said cable to be taken up by said wheel means to thereby raise said sinker means on said loop portion, and reversing said directions of rotation causing said cable to be fed from said wheel means to thereby lower said sinker means on said loop portion.

A downrigger for operating a cable to raise and lower a sinker selectively and to feed and take up cable selectively independently of substantial movement of said sinker, comprising:
- a. a shaft,
- b. means for supporting said shaft for rotation,
- c. first wheel means fixed on said shaft for rotation therewith,
- d. second wheel means mounted for selective rotation on said shaft,
- e. said wheel means being constructed and arranged for engaging with opposite end portions, respectively, of said cable such that an intermediate portion of said cable may form a loop between said first and second wheel means for supporting said sinker means translatably relative to said cable,
- f. handle means on each of said wheel means for rotating said wheel means, and
- g. means for selectively engaging and disengaging said second wheel means with said shaft, whereby when said means is engaged said wheel means are rotatable jointly to translate said cable relative to said sinker means and transfer said cable from one wheel means to another to thereby maintain the distance between said sinker means and wheel means substantially constant and when said second wheel means is disengaged both of said wheel means are rotatable in first opposite directions to extend said intermediate portion of said cable and in reversed opposite directions to take up said cable.

A downrigger for fishing, comprising:
- a. support means,
- b. a shaft journaled for rotation on said support means, the axis of said shaft being nominally horizontally disposed,
- c. first wheel means fixed on said shaft for rotation therewith on one side of said support means,
- d. second wheel means mounted for rotation on said shaft on the other side of said support means,
- e. said wheel means being rotatable in nominally vertical planes about said shaft axis and being constructed and arranged for winding and unwinding a cable,
- f. means for selectively engaging and disengaging said second wheel means and said shaft for selective joint and individual rotation of said wheel means, respectively,
- g. a cable having opposite end portions attached to said wheel means and having a continuous intermediate portion between said end portions,
- h. said cable extending tangentially from generally opposite sides of the peripheries of said wheel means, respectively,
- i. first and second sheave means supported for rotation in spaced relation from and in substantial alignment with said first and second wheel means, respectively, said cable running over said sheave means from each wheel means for forming a loop in said cable,
- j. pulley means for supporting a sinker, said pulley means being supportable in said cable loop, and
- k. handle means on said wheel means, respectively, for rotating said wheel means manually, whereby when said second wheel means is disengaged from said shaft means one and another of said wheel means may be rotated in first opposite directions to feed said cable from said wheel means for lowering said sinker and may be rotated in second opposite directions to take up said cable on said wheel means and when said wheel means are engaged and rotated in the same direction said cable will transfer from one wheel means to the other translatably relative to said sinker means.

A downrigger comprising:
- a. first and second spaced apart coaxial wheel means,
- b. a bearing support between said wheel means,
- c. a shaft journaled in said bearing support, said first wheel means being fastened to said shaft and said second wheel means being rotatable thereon,
- d. means for selectively engaging and disengaging said second wheel means relative to said shaft to enable joint and individual rotation of said wheel means, respectively,
