Abstract:

A slide block breech mechanisms for artillery weapons has multiple lugs on each side thereof for sliding engagement with oppositely contoured flutes in a breech ring. The lugs are shaped to vary the bearing surface area and angular interface with the flutes so that each lug transmits substantially the same amount of stress to its contacting flute as each of the other such lugs, thus avoiding the high stress levels produced by concentrating all loads on a single pair of lugs.
