Abstract
A percussion-ignitable type tube primer has a closed end, thin walled metal tube, which is longitudinally indented over a portion of its length. The indention of the metal tube defines a convex anvil in the interior of the tube. The indented portion of the tube contains a percussively-ignitable primer mixture which ignites and deflagrates when the wall of the tube opposite the convex anvil is deformed by an impact or blow occasioned by a striking hammer or a pin. The primer is made by introducing a fluid paste of the primer mixture into the tube, indenting the tube and subsequently drying the primer mixture.
