5. Interlocks Torpedo tubes were fitted with a number of interlocks, which prevented improper operation of the torpedo tubes which endangered the safety of the boat. A common element of these interlocks was an interlocking rod.- An interlock preventing simultaneous opening of breech and muzzle doors of torpedo tube consisted of an angle plate attached to a rotating ring which locked the breech door, interlocking rod and the operating shaft which opened muzzle door. The operating shaft could be rotated only when it was not blocked by the angle plate - the rotating ring was in position locking the breech door. When the shaft was rotated, it moved the interlocking rod back toward the rear end of the tube by means of the screw gear and locked the angle plate preventing rotation of the locking ring and the opening of breech door.- The firing rod had to be recocked before opening the torpedo tube breech door. Firing rod recocking caused retraction of the torpedo stop bolt into the tube and lifting of the trigger latch. When fired, the firing rod was moved back towards the rear end of tube entering a special socket on the rotating ring locking the breech door. The ring could be rotated only after recocking the firing rod. The interlock preventing launching a torpedo when the muzzle door was closed was composed of safety catch locking the firing rod. The safety catch was pulled out while opening muzzle door.- The tube drain valve was locked in the closed position by the feather on the interlocking shaft. When the drain valve was opened, a sliding bolt operated by the link gear from the valve handle, prevented revolving the muzzle door operating shaft. - The mine discharge gear master valve couldnt be opened when the muzzle door was closed - the valve was locked by the feather on interlocking shaft.- The mine discharge gear master valve couldnt be opened when the mine stop bolt was retracted - the valve was locked by the link gear from the stop bolt operating shaft- Launching the torpedo when the mine stop bolt retracted was prevented by the link gear connecting the stop bolt with the firing rod.
