ABSTRACT:
In a nonelectrically initiated delay booster assembly which includes a booster shell containing an explosive material, a cap well extending through one end of the booster shell into the explosive material, a detonating cord tunnel surrounded by a shock absorbing material affixed to the side of the booster shell or enclosed inside the booster shell and a detonating cord laced through the tunnel, there is provided a delay insert which consists of a sensor, signal carrier and nonelectric cap assembly for transmitting detonation from the detonating cord to the explosive material in the cap which cap is inserted in the cap well of the booster. The signal carrier extends from a point within the cap to a point externally of the booster shell and adjacent the detonating cord extending through the cord tunnel, and the sensor initiating member is affixed to that end of the signal line lying externally of the booster shell in such a manner that it lies in initiating relationship with the detonating cord.
