More specifically, it is an object of the invention to

This invention relates to a pear preparation machine 10 preparation machines which will provide a bridge be

the machine must meet certain basic requirements among
Still another object of the invention is to provide an'

Such seed celling processes, however, provide a fruit which
is less desirable from the standpoint of appearance of the

seed celling mechanism.
In conjunction with the foregoing object it is another
object ¿of the invention to provide structure for halving
the fruit during discharge thereof from the seed celling
prepared fruit, particularly when halved. It is desirable

In addition to improving the appearance of the pre
pared fruit, the provision of a bridge between the seed
cell cavity and the blossom end of the fruit results in
an increase in the ratio of the tonnage output of fruit
from the machine to the tonnage input of fruit to the ma 50
chine. This increased yield of prepared fruit is important
economically.
Certain pear preparation machines heretofore which
have been designed to provide a good appearance of fruit
and a high yield have required that the pears fed thereto
be closely graded as vto size and shape. The grading of
the pears adds another element of cost and requires addi
tional machinery and manpower. It is desirable that the
pear preparation machine and particularly the seed cell»
