Abstract A metal fuze extension with an explosive-filled channel passing through it. The channel is small on one end and large on the other end with a conical section in the middle. A small conical insert fits into the conical portion of the channel. An opening extends from one end of the insert to the other allowing communication between the large and small ends of the channel. The large end of the channel is filled with an explosive charge. In the intended use of the extension, it is so positioned that the end containing the large diameter channel extends through the plate (usually steel) which forms the end of the canister. A detonation wave from a fuze located at the small end of the channel passes through the opening in the conical insert and causes detonation of the explosive material in the large end of the channel. The insert is then forced into the smaller end of the channel closing the smaller end of the channel and also the opening in the insert and the end of the plug is expanded so that the plug assumes the external configuration of a bottle stopper, preventing its ejection from the burster tube.

Claim 1
Independent Claim
156 words
In an explosive device including a burster charge and a fuze, fuze extension means situated between and contiguous said charge and said fuze; said extension means comprising: a tubular body of flowable metal having a channel extending therethrough and communicating said charge with said fuze; a portion of said channel near the middle of said channel being conical; the larger end of said channel being in contact with with charge; the smaller end of said channel being in contact with said fuze; a conical insert located in said conical portion of said channel; an opening extending through said insert and communicating said larger end and said smaller end; and said larger end being filled with explosive material; whereby detonation of said explosive material causes said insert to be forced into said smaller end preventing backfire through said extension means and expands the extension prevent its ejection and resulting backfire through the opening which would thus result.
