Cartridge belt for self-loading mortar

摘要

The cartridges (1,1') are accommodated alongside each other inside close-fitting links (7), each of which has opposite protrusions (15,17), each containing an opening (11). Adjacent links hinge together via pins (9) passing through the openings and thickened at the ends. The opening in the first protrusion (15) is connected to the belt edge by a passage (13) narrower than the opening and also than the portion of the pin passing through it. A second opening in the link is connected by a second passage (13') to the belt edge. Thus by bending the passages slightly open adjacent cartridges can be slid free in either axial direction. The two passages (13,13') can lead to the same edge of the belt. The thickened portions at the pin ends can consist of transverse lugs, situated symmetrically in relation to each other. They can be rectangular, so that they cannot turn in the links.
