Title: Improvements in or relating to cartridge cases
IPC: F42B5/30
Filed: 1944-09-04
Abstract: 585,889. Moulding cartridge cases. ROBERTS, H. A., and DICKSON, W. Sept. 4, 1944, No. 16813. [Class 87 (ii)] [Also in Group XXI] In moulding a cartridge case from plastic material the cap chamber 3 is embedded in the base 1 so that its inner end abuts against the inturned flange 4 at a predetermined distance from the end face and its flange 6 is below the surface. The mould has two members, one forming the end face of the base while the other forms the inside of the cartridge case. The cap chamber 3 is placed over a locating pin (not shown) in the base moulding member. The two moulding members approach to a definite distance, and the inner end of the cap chamber is therefore always at the same distance from the base. Exact uniformity in lengths of cap chambers is not essential, since variations will be compensated for by variations in the depth to which the flange 6 is embedded.
