Claims (5)

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:
1. In apparatus for launching, towing and recovering a submersible and towable body from a vessel, where said apparatus includes: winch means for storing cable, at the outer end of which cable said body is secured; rotatable sheave means over which said cable runs, said sheave means having an axis of rotation; saddle means against which said body is secured when i its stowed position; and means for mounting said sheave, saddle and winch; the improvement comprising: roller box means mounted for rotation about an axis of rotation which is substantially co-extensive with the axis of rotation of said sheave and parallel thereof; said roller box means comprising a frame, a pair of side rollers in said frame and situated so that one of said pair of side rollers lies on each side of said cable when said body is being towed and said cable extends downwardly from said sheave to said body, and a nose roller at one end of said frame adapted to contact the forward edge of said cable when said body is being towed; and bias means to effect rotation of said roller box about said axis of rotation so as to maintain substantially constant pressure of contact between said nose roller and the forward edge of said cable.
2. The apparatus of Claim 1 where said pair of side rollers and said nose roller are mounted so that the directio of the axis of the nose roller is substantially perpendicular to the direction of the axis of each of said side rollers ; and so that during normal towing operation when said cable extends downwardly from said nose roller^and substantially in above with is adapted to' maintain the position of said roller box with respect to said cable so that the direction of the axes of said side rollers, the direction of the axis of said nose roller, and the direction of the axis of said cable as it passes through said roller box in contact with said nose roller, are all mutually perpendicular.
3. The apparatus of Claim 2 where said bias means includes cam means adapted for rotation about the axis of rotation of said sheave together with said roller box, and a cable wrapped around said cam and secured at its end remote from said cam to spring means.
4. The apparatus of Claim 3 where said spring means includes an hydraulic cylinder pressurized by an hydraulic accumulator.
5. The apparatus of Claim 2, 3, or 4 where said cam means is such that as said remote end of said cable is drawn by said cylinder away from roller box and said roller box rotates about the axis of rotation of said sheave, the torque provided by said cable as it is wrapped around said cam to said roller box varies substantiall directl as
