This invention relates to improvements in magazine rockets of the general type disclosed in my prior application Serial No. 201472, filed November 12, 1917. In this type of rocket a relatively small charge of explosive is ignited in the combustion chamber and the gases generated by the explosion are expelled through a tapered nozzle connected to the lower end of the chamber. A movable breech block is provided for closing the upper end of the chamber, and automatic devices are also provided for removing and replacing the breech block after each explosion, thus permitting the insertion of a fresh cartridge. It is the general object of my present invention to improve the construction of magazine rockets of this type, simplifying the manufacture thereof and rendering the mechanism more reliable in operation. With this general object in view, one feature of my present invention relates to the provision of devices for operating the reloading mechanism, such devices being actuated by the pressure of a portion only of the gases escaping from the combustion chamber. By this arrangement the forces to be controlled are materially reduced. In the embodiment of my invention herein shown, I provide a movable member directly actuated by a portion of the escaping gases and controlling the operation of the reloading mechanism. Another important feature of my invention relates to devices for locking the breech block in the combustion chamber, and for releasing the breech block after the pressure of the explosion in somewhat reduced. Further features of my invention relate to devices for correcting deviation of the rocket from the true line of flight, to improved supporting structures for the several parts, and to an improved and simplified firing mechanism.
