Abstract: A holder for fireworks comprising a pair of rigid uprights of sheet material and a number of rigid plates or shelves of sheet material extending between the uprights. Slots in the respective components provide for assembly into a self-supporting fireworks holder by the relative telescoping of the uprights through the slots. Legs of sheet construction are also telescoped through slots in the upright and interlock with slits in the baseplate to rigidify the structure. Holes in some of the plates hold the fireworks in position for firing. The baseplate is substantially free of holes to serve as a shield to prevent inadvertent ignition of materials proximal to the holder.

Abstract: A system which disperses a payload sequentially. The payload may consist of a number of discrete individual units or a long string of units. The illustrated and described embodiment of the system is utilized in a rocket for dispersing decoy material, such as aluminum chaff, in a sequential burst pattern. The concept may readily be applied to mortor type decoy rounds, other types of decoy material, or to other types of applications requiring a sequential dispersion of the payload thereof.

Abstract: A system which disperses a payload in a sequential manner. The payload may consist of a number of discrete individual payload units which are composed of two or more sections. The illustrated and described embodiment of the system is utilized in a rocket for dispersing decoy material, such as aluminum chaff, in a sequential burst pattern so as to produce a more uniform, widespread distribution of the decoy material. This is accomplished by sequential bursts of each unit which throw outwardly the payload sections of each unit, whereafter each of the payload sections are exploded. This concept may readily be applied to mortor type decoy rounds, other types of decoy material, or to other types of applications, requiring a sequential dispersion of the payload thereof.

Abstract: The forward end of a rocket motor is attached, by a threaded adapter, to a cylindrical housing that is in turn attached to an elongated tube, the opposite end of which is fitted with a releasable nose cone. The elongated tube is filled with a series of bombs. Each bomb is a conical, shaped charge equipped at one end with a parachute protected by a split, conical, plastic shield loosely held together by a band and a pronged clip--all of which is seated in the conical recess of an adjacent bomb. A conical partition separates the tube from the housing; and the main parachute is attached in the housing. An acceleration actuated fuse in the adapter ignites a time delay charge, which ignites an explosive charge that when exploded forces a piston against the housing, so that it separates the housing and tube from the adapter and rocket.
