Definitions

• the invention relates to a method and a device for moving a torpedo, said torpedo being released from a radially and an axially fixed position in a carrier and being moved axially in forward direction along said carrier towards a torpedo tube arranged on a distance from said carrier exceeding the length of said torpedo.
• torpedos In a submarine armed with torpedos and provided with torpedo tubes said torpedos normally are fixed in chutes or the like during operation of the submarine. To become combat ready the torpedo must be moved from said carrier to said torpedo tube, said tube then being closed. As the torpedo tube has to be available to the loading operator said carrier does not reach all the way to said torpedo tube, and therefore problems arise when the last section of the torpedo is moved the distance between said carrier and said torpedo tube.
• An object of the present invention is to overcome the above-mentioned problems. Another object is to simplify the handling for the loading operator, among other things to avoid heavy lifting. To achieve the objects referred to above the device according to the invention has the characteristics appearing from claim 1 and claim 3, respectively.
• FIG. 1 is a side-elevation view of a device according to the invention
• FIG. 2 is a cross-sectional view of a part of the device according to the invention
• FIG. 3A and 3B are perspective views of the device according to the invention in a starting position
• FIG. 4A and 4B are perspective views of a part of the device according to the invention.
• FIG. 1 shows the arrangement in principal of a torpedo 10 positioned in front of a torpedo tube 11 in a submarine.
• the torpedo in FIG. 1 for drafting reasons is cut in two places and in reality is longer in relation to the person appearing in FIG. 1.
• said torpedo is fixed, by means of bands 12,13, in a guideway 15 shaped as a chute.
• the distance between said chute and said torpedo tube is far smaller than the length of said torpedo.
• a so called loading means 14 is releasably mounted in the rear part of said torpedo.
• Said loading means comprises a loading means head 14A and a loading means holder 14B, which is attached to said torpedo.
• said chute is formed with two skid rails 20A and B, on which said torpedo slides during its movement towards said torpedo tube. Between said skid rails is arranged an elongated three part guide bar 21 having a U-shaped cross section. Inside, on the base of said guide bar runs one part of said chain 16. The return part of said chain runs on the underside of said guide bar 21.
• a twin rack 18 is slidably disposed on two ledges 22 extending inwardly from the vertical stems of said guide bar. The teeth of said twin rack 18 are arranged approxi ⁇ mately in level with the upperside of the stems of said guide bar.
• the outlook of said loading means 14 is shown on FIG. 3A and FIG. 3B.
• Said loading means holder 14B comprises also a coupling 26, which is releasably connected to said torpedo (see FIG. 4A) .
• said adjusting screw 23 is screwed up, whereby a larger gear wheel 27 carried in said loading means is lifted out of engagement with said chain 16, which in this position is standing still.
• the adjustment screw 25 is screwed up whereby ratches 29 (see FIG. 4A) pivotally carried in said twin rack under spring biasing are lowered down in recesses 30 in the upper part of the stems of said guide bar 21, thereby locking said twin rack 18 in relation to said guide bar 21.
• the adjustment screw 24 is screwed down, whereby a driving rod 31 (see also FIG. 4B) engages said chain 16.
• the adjustment screw 23 is now screwed down and said larger gear wheel 27 engages said chain while at the same time two smaller gear wheels 28 arranged on the same shaft as said gear wheel 27 engages said twin rack 18. Also said adjustment screw is screwed down to release said twin rack 18 from said guide bar 21 by said ratches 29 being pressed downwardly and pivoted out of position in said recesses 30. At the same time said loading means holder 14B is fixed in said twin rack. Said adjustment screw 24 is screwed up and releases said driving rod 31 from engaging said chain.
• the two main parts of said loading means i.e. the loading means head 14A and the loading means holder 14B are releasably connected.
