8. The depth setting parts of this pistol are housed in a casing. The flange of this casing secures the pistol assembly in the central tube of the depth charge case. The index pointer and dial are mounted on the outer surface of the flange to permit adjustment of the pistol when it is installed in a depth charge. An inlet valve assembly is mounted in the center of the index pointer assembly. |

9. Parts inside the casing are the bellows, a depth-setting sleeve, an adjusting bushing, a depth-setting spring, a piston stem. A collar is secured to the outer end of the stem in such a position that inward motion of the stem causes the collar to take up against the spring. After this has occured further motion of the stem requires compression of the spring. A piston secured to the stem is also attached to the inner end of the bellows, while the outer end of the bellows is connected to the pistol flange by a bellows exten-sion. The bellows and bellows extension provide a watertight, expansive housing for the depth-setting sleeve and spring and the adjusting bushing |
