Nebelkerzenabwurfvorrichtung


The Nebelkerzenabwurfvorrichtung was a rear mounted grenade dispenser used to disperse the Schnellnebelkertze 39 smoke grenade. It was typically found on German tanks from 1939 through 1942. The device carried five smoke grenades, each grenade being held in position by spring loaded catches. The vehicle commander released the grenades one at a time by wire control which operated a ratchet coupled to a camshaft.
Each pull of the control wire rotated the camshaft one fifth of a turn, releasing a smoke grenade, the pin of which was drawn out by a fixed chain, and the ratchet was returned to its original position by a second spring. Five pulls on the control wire would release all five smoke grenades in succession, enabling the vehicle to reverse out of sight into its own smoke screen with the grenades discharging smoke for about 100 to 200 seconds. Later examples of the Nebelkerzenabwurfvorrichtung were fully enclosed in an armored box. The Nebelkerzenabwurfvorrichtung was discontinued beginning in April 1942 because it had not proven to be effective, the main disadvantage being that the resulting smoke screen built up behind the vehicle. It was succeeded by the turret mounted Nebelwurfgerät launcher.
