Construction of body: The container is formed be three interlocking lengths of corruga-ted sheet steel, closed at each end by hexagonal sheet steel plates. The three inter-locking lengths are held in position by four encircling sheet steel bands and buckles. The buckles are prevented from opening by two arming wires. To a hub on the exterior of the after end plate are attached three bungee cords 7 1/2 inches long, to each of which is attached a steel hook. Each hook fits into a hole in the side of each section of the con-tainer.

One of the three interlocking corrugated lengths serves as the upper portion of the hori-zontally suspended container. To this upper portion is spot welded a smooth semicircular sheet steel piece 31 1/2 inches long, in the center of which is located the suspension lug. On each side of the lug, between it and the in-board steel bands, there is welded an eyebolt to take the arming wires.

Operation: When the container is released from the plane, the arming wire is withdrawn. The buckles open and the steel bands fall away. The three sections of the body sepa-rate, allowing the bombs to fall free.

Remarks: Fitted around the container there may be a safety device consisting of a can-vas strap, a black powder burster charge in a small container, and a friction igniter with a 2-second delay. The igniter cord is attached to the arming wire and as the container leaves the plane the delay train is ignited. After 2 seconds, the strap is blown apart and the section of the container fall free.
