The invention relates to apparatus for clean
ing the surfaces of eggs and the like, and has for
one of its objects the provision of an improved
machine for this purpose, of relatively simple and
inexpensive construction and which will be more
eiiicient in use lthan those which have been here

egg, said members also having van abrasive sur

Referring> more particularly to the said draw-` l l
, ings, the machine comprises a framework which
may rinclude upright members II, longitudinal
member l2, i3 and I4, and transverse members
I5 and I 6. ` The longitudinale I2 and I3, which
are here shown as ofv angle iron, are inclined to
the horizontal at an angle of about 15°, and re
spectively serve as supports and guides for the
upper and lower runs of sprocket chains l'! which
are trained about sprocket wheels I8 and I9 car
ried by shafts 2B and 2l journalled in bearings -'
' 22 carried by the uprights Il. The shaft 20 is
driven .through
2li-here shown
from a motor
mounted on the

with their abrasive ‘surfaces 33 inward, and which
are _readily removably vsecured to the chains as

which certain transversely opposed pair‘s'fo'f .the

The operation of the apparatus will be readily
apparent from the foregoing, it being understood
that the eggs will be supplied to the right hand
end of the machine by the feeding device 38,
where they will be sequentially picked up by the
pocket members 32 and advanced upwardly along
the upper run of the'belt 29, which serves asa
support for the eggs. By reason of their ovate
shape the eggs of course will not turn true about
their longitudinal axes, but will wobble and may
speed reducing drives 23 and
even turn end over end at times. This,>together

with the contour accommodation afforded by the

cleaning engagement with one or both of the
abrasive surfaces 30 and 33 and that the eggs
horizontal and having an abrasive surface over
will be thoroughly cleaned by the time they reach
the left hand end of the machine, where they
will be discharged to the delivery chute or mech
anism 39.
The -downward inclination of the belt
2S, as well as its motion in a direction opposite
to that in which the eggs are advanced, both tend
to prevent the eggs from leaving the pockets 32. î
