The apparatus permits operations such as the
following. Assume for example that the tray Il)

is being used as a receiving tray, in the compart
compartments of the tray IG, such filler lots of
eggs 35, each such lot being in assembly with its
paper board filler 36 and underlying paper board
flat 31, all as in a layer in a crate compartment.
ments of which have been placed filler lots of
The paper board flats used in egg crates are
commonly but not always of the embossed type
shown at 31 in Fig. 3. An advantage of such ern
bossed flats is that after lifting out a paper board
filler from the crate the layer of eggs left stand
ing on end on the cup-like seats of the under
lying flat can be picked up as a unit and lifted
out of the crate by means of a convenient device
hereinafter referred to as an egg lot lifter. Such
a device, of which there are several known forms
or types used in egg handling plants, comprises
a light rectangular frame having a basket type
handle and egg engaging means within the
frame. After a paperboard ñller has been re
moved from a crate, the device can be let down
in the crate with its frame enclosing the layer
of eggs and, by manipulation of an actuating
means, will engage and hold the eggs in their
eggs
in this instance in assembly with their
paper board nllers 38 and underlying paper board
ilats 31. The second tray Il is now swung over
and upon the tray I0, as in full lines in Fig. 3,
whereupon the two trays are swung together to
the upside downposition indicated in dotted lines
in said figure. The swinging of the trays in folded
relation to the right from the position shown in
full lines in Fig. 3 to the dotted line position shifts
the freely movable carriage 8 to the left. The
iirst tray I0 is then swung off from-the second
tray l l and back to its normal horizontal position
on the carriage, leaving the eggs',fii1lers and ilats
supported on the tray Il, the eggs standing on
the seats therefor in said tray Il and the paper
board flats lying over the eggs. The flats are
now removed. If the carriage 8 is not already in
position for registering the light apertures of
the egg holding tray il with the subjacent lenses
i2, it is easily shifted by very slight effort to effect
`such registration, whereupon the apparatus is
ready for candling, in the relative positions of the
proper spaced relationship. The device with thel
parts shown in Fig. 4. The eggs are now candled
layer of eggs retentively held by it canrthen be
lifted out from the crate, and, by manipulation 30 by examining them in illuminated condition with
in the compartments of the fillers. Such exam
of its actuating means, will be caused to release
the eggs. The device may therefore be used for
lifting a layer of eggs from a crate and releas
ing them into the compartments of a filler in
another crate o1' into pockets in egg candling
apparatus or into a receptacle. In short it is a
convenient transfer device for a layer or filler lot
of eggs. But the device cannot be used for re
moving eggs from crates using unembossed flats,
for the reason that upon removal of a ñllerfrom
the layer of eggs resting on an unembossed flat
the eggs will immediately tumble over on their
sides and become disarranged. Hence an egg
ination in the fillers is advantageous as it permits
the eggs to be observed each illuminated by the
light passing through it without interference by
diñused light from adjacent eggs. A further ad
vantage is that the illumination of the eggs while
within the ñllers shows off well their relative sizes,
and thus candling in the fillers facilitates sort
ing as to sizes.
After this ñrst candling, the tray I0 is swung
over and upon the tray ll, as in full lines in
Fig.
whereupon the two trays are swung to
gether to the reinverted position indicated in
dotted lines in said figure. The swinging of the
handling apparatus which would require or de

normal horizontal position on the carriage, leav

that case there would be no way of putting the 50 ing the eggs and fillers supported on the tray I0.
Assuming the carriage to have been shifted to po

sition for registration of the light apertures of

it is often desirable to use an egg lot lifter for

transferring Vlayers of eggs from crates to can

presented for the first candling, or standing on
would exclude the use of the egg lot lifter for
the opposite ends from those on which they stood
that purpose would accordingly be somewhat

limited in its utility. Now an advantage of the
