An old machine, made several years
ago for destroying railway IcKets, mas
been introduced on a large scale to meet
the requirements of the West African
rubber merchants in the cutting up OF
raw rubber into shreds. By this pro-
cess the moisture is exuded and the rub
Der can be packed into less space for
shipment. The machine consists Of
two sets OF disks with very sharp edges,
carried on wooden frame. These disks
are placed at suitable distances and
slightly intersect each other. Above
them is wide-mouthed hopper. Each
set Of disks, which are driven by hand,
with ordinary gear, revolves toward the
centre of the machine, and as the raw
rubber is fed into the machine it is inn
mediately grasped and cut into shreds,
which are combed out underneath and
discharged.
