Abstract
This invention, relating to the art of resizing and decapping fired cartridge cases, comprises a novel method of and apparatus for automatically and safely resizing spent cartridge cases having primer caps, including means for automatically resizing the cases and clearing the case of the spent primer therein, in a highly efficient, automatic procedure, uniformly restoring cartridge cases for reuse. Pursuant to the invention means are provided which automatically orient the fired cases and feed them to a case receiving station from which they are sequentially advanced to a registration station, where swaging or sizing of the outside dimensions of the case to their original dimensions is effectuated and the case is decapped and reclaimed for reuse; the so resized and decapped case is displaced from the apparatus simultaneously automatically on positioning the next case at the registration station for repetition of the procedure.
