Zusammenfassung:23,288. Hoyle, J. R., and Strange, H. B. Oct. 12. Projectile fuses.-Relates to percussion fuses of the type in which a diaphragm closing the flash passage is perforated by a punch on impact. According to the invention, a pellet D carries a needle E and a number of punches F which, normally, hold the pellet D at safe, but, on impact, perforate a diaphragm H mounted as shown and allow the pellet D to move forward and fire a primer G the flash from which passes through the perforated diaphragm and the passages B to powder pellets J and fires the explosive charge of the projectile. The pellets J may delay the action. Screws N &c. prevent the rotation of the pellet D, which may be further locked by usual centrifugal bolts. A hole A allows an accidental flash to escape to an annular space C where it is ineffective. A spring L prevents rattling.
