cleaning machines.
~ way and slideway mounting.
The main object of this invention are:
First, to provide an egg cleaning machine by
Fig. 10 is a fragmentary perspective view of the
carriage with a tray cover member mounted
which eggs may be rapidly and effectively cleaned
with a very small amount of breakage.
Second, to provide an egg cleaning machine
which is simple and economical in structure and
at the same time of large capacity.
Third, to provide an egg cleaning machine
thereon.
Fig. 11 is a fragmentary side elevation of a
modified form or lembodiment of my invention,
the modification being mainly in the type of
cleaning brushes and the driving means there
for.
having these advantages which vmay be operated
by persons of little mechanical skill.

Fourth, to provide a tray for egg cleaning ma
chines which eñectively supports the eggs while
permitting their rotation on the long- axes of the
eggs.
Fifth, to provide in an egg cleaning machine a _
tray which, while effectively supporting the eggs,
minimizes the wear on the brushes.

The eggs are arranged with their long axes
transversely of the path of travel of the carriage,
and they are rotatively supported in their seats
