Abstract:
A fireworks aerial display shell is provided with lift charges positioned at opposite ends of a casing that additionally contains an effects charge. Fuses are operatively associated with the lift charges and the effects charge in a manner to ignite the lift charges a period of time before igniting the effects charge. When either one of the ends of the casing is placed facing a closed bottom of a launch tube of a reusable mortar, the burning lift charge at that end of the casing when ignited exerts a propelling force to propel the aerial display shell upwardly out of the launch tube to an intended height before the effects charge is ignited to create a pyrotechnic visual effects display.

Claim (Index 21):
A consumer fireworks aerial display shell comprising:\n a cylindrical casing having first and second ends and defining an interior volume, said cylindrical casing having a longitudinal length of between 90 and 110 mm and an outside diameter of between 40 and 44 mm; a first lift charge comprising 7 to 9 grams of black powder positioned in the interior volume of the casing at the first end of the casing and operable to cause a propelling force to be directed toward the first end of the casing after the first lift charge is ignited; a second lift charge comprising 7 to 9 grams of black powder positioned in the interior volume of the casing at the second end of the casing and operable to cause a propelling force to be directed toward the second end of the casing after the second lift charge is ignited; an effects charge positioned in the interior volume of the casing between the first lift charge and the second lift charge and separated from the first lift charge by a first partition extending across an inner cross section of the casing and positioned between the first lift charge and the effects charge and separated from the second lift charge by a second partition extending across the inner cross section of the casing and positioned between the second lift charge and the effects charge; a lead fuse operatively associated with the first lift charge for causing ignition of the first lift charge; a connection fuse operatively associating the first lift charge with the second lift charge to cause the second lift charge to ignite less than one second after the first lift charge ignites; and a delay fuse operatively associating the effects charge with the first lift charge for causing a delayed ignition of the effects charge after ignition of the first lift charge or with the second lift charge for causing a delayed ignition of the effects charge after ignition of the second lift charge, wherein less than a total of 60 grams of pyrotechnics is present in the first and second lift charges, the effects charge, and the lead, connection and delay fuses.
