This invention relates to ammunition belt load
ing machines in generaLand in particular to a
modification thereof in the form of an adaptor
prises-a framework having two similar end pieces
providing for unloading operations.
It is frequently necessary to unbelt and rebelt
ammunition. When ammunition is unbelted by
hand, the link is often twisted so as to bind, and
a much greater force is required to free the car
tridge from the link, resulting in forcing the
