|A1136...Rifled artillery projectile, Dahlgren design, Federal manufacture, blind shell with brass cap, lead cup sabot, Dahlgren 30 pounder rifle, 4.4in. |
Projectile was manufactured in the Federal arsenals following the design of John Dahlgren. The pattern employed a lead cup sabot with a groove in the middle on which greased twine was affixed, this to lubricate. The bottom of the projectile was cast with five ribs onto which the lead cup sabot was affixed. In addition four raised ribs were placed on the side, which were slightly wider than the rifling grooves in the cannon and designed to guide the projectile through the bore, but without catching on the grooves. These projectiles were cast with a cavity, the casting sand was usually left in the core, unfinished hole was plugged with a small brass plug, giving it the effect of a light bolt. This was probably intended as a transitional measure to test the pattern, the shell could be drilled and fitted for fuzes at a later time. These "blind shells" never had an explosive charge, the black substance sometimes found inside is foundry sand from the mold for the core. Projectile measures:diameter 4.37in., length 9.5in. (excluding fuze), weight 24.7lb. Sabot is not fired and intact. Brass nose cap is missing. Metal is solid, minor areas of pitting. Projectile is disarmed: open fuze hole exposes empty interior. Recovered: Port Hudson Louisiana, by Emile Mancuso.
