The purpose of the Type L apparatus is to lay a curtain of aerial mines in the path of low level or dive bombing aircraft.
The Canister Mk I consists of a conical upper container, which is connected to the tail of a 2 inch rocket motor by a short rod and a stirrup. In the upper container are a parachute to bring down the spent motor, etc., the main support parachute, a bomb steady parachute, and the bomb. These items are all held in position by three retaining cords, which are controlled by an explosive link.
The swivel on the lower end of the bomb is connected to the top end of a 1,000 ft. coil of steel piano wire, which is contained in the lower container. The wire from the bomb passes to the top of the coil through a slot cut in the central tube. The central tube is provided to aid in unspooling the wire and avoid failures due to kinking. The lower end of the 1,000 ft. coil of wire passes back through the slot in the central tube and is connected to a long, light shock absorber, whose lower end is attached to the drag parachute assembly. This latter consists of a 32 inch drag parachute housed, in a bag and prevented from opening on the initial jerk at pick-up by four retaining cords controlled by an explosive link. The junction between the upper and lower containers is effected by crimping parts of the base of the upper container lightly over the top of the lower container. .
The electric leads for igniting the electric delay fuzes extend from the base of the lower container and terminate in a two pinned plug which fits into a socket on the projector.
No information about functioning.
