"This invention relates to a rocket apparatus of the type in which small portion of the explosive charge are fired successively within a combustion chamber of small capacity but of great strength relative to the remaining structure. Such an apparatus is shown in my prior Patent No. 1103503 granted to my July 14, 1914. It is the object of my present invention to improve and simplify the construction therein shown, said improvements resulting in increased economy of manufacture and in increased certainty and efficiency of operation. With this general object in view one feature of my invention relates to the construction of a rocket apparatus of the type defined, in which the breech block is mounted for movement within the casing and in which the block in its travel extracts the empty shell from the fixed combustion chamber and inserts a fresh shell therein, this operation being repeated until the supply of cartridges in the casing is exhausted. A second feature of my invention relates to the provision of means for firing each fresh charge after the breech block is seated, and in particular, to means for firing charges at predetermined time intervals, this latter provision being of prime necessity when accurate flights are required. Another feature of my invention relates to the provision of a special type of cartridge and explosive by which the efficiency of the apparatus is much increased."
