This invention relates to food handling appa
ratus of the type in which a commodity tobe
sliced is reciprocated past an exposed portion of
the edge of a rotary circular knife, being slid along
a thickness gauge plate lying substantially in the
plane of the edge of‘ the. knife, so that a slice is
severed from the commodity each time it passes
the exposed portion of the. knife.
A basic problem which has faced slicing ma
chine designers has'arisen from the fact that the

commodities to be sliced on each machine are of
many sizes and shapes, and means must be pro

commodities so that they can be supported while
being carried past the cutting edge of the knife
taken substantially from, the position indicated
and can be moved toward the plane of the knife

It is an object of this invention to provide com
modity-feeding means for a slicing machine which

is adapted to handle variously shaped commodi
ties of many different sizes.
