Abstract: To permit automatic ejection of shells in a progressive shell loader, a cam is mounted near the turret holding the shells. As the carriage is raised and lowered, two pawls and an index wheel turn it so that the shells advance toward a final station. Immediately prior to the final station, the cam engages a spring-biased lever to cause it to eject the reloaded shell. The pawls engage camming surfaces formed on the bottom of a single-piece index wheel to turn it.

Abstract: An elongated flexible bag is fitted inside templates that have aligned openings therein corresponding in shape to that desired for a solid rocket motor propellant bore. With the bottom sealed, the bag is filled with a multiplicity of solid pieces each having a cross section substantially less than that of the bag. When filled, suction is applied to the bag by a vacuum needle to exhaust air therefrom until the bag is very tight on the solid pieces contained therein. The vacuum needle is then withdrawn, the hole made thereby is sealed, and the templates are removed from the bag. After use in loading a solid rocket motor with propellant, the bag is cut open, the solid pieces are removed, and the bag is peeled out of the bore in the propellant.
