The requirements Of the egg trade
and certain state and federal food reg
ulations make II necessary for the
shipper TO know what quality of eggs
he is shipping TO consumers. This
means that all eggs should be tested
by candlIng In the producing section.
storekeepers and egg buyers in the
towns can candle by means OF n
shielded light in a dark room. The
travelling collectors. however, who
gather eggs from the farmers, lack
these facilities. To assist these col
lectors. the egg-handling specialists Of
the department have developed a
simple homemade electrical Gambling
outfit that cen be used out of doors.
The apparatus can be fastened TO the
side or back Of a wagon or TO the wall
OF a building at a height convenient
for the candler.' II hung on hooks, It
is easily removed.
This device consists OF a wooden
case Gig. ~. painted black inside and
out, In which Is mounted an inexpen-
slye egg candle lighted by n tiny elec-
trio bulb operated by dry batteries.
The eggs are passed into the bottom
part Of the box through an opening
protected by black cloth curtains that
prevent light from entering Gig. /,
~. AS the eggs are held and turned
before the candle the collector can
tell their quality by looking through
the eyehole in the front of the case
(Fig. /, o..
To Build Case.
The following directions and dImen-
sions have been tested and found sat
isfactory In making these outfits:
Make light wooden box, 26 inches
high, 1S inches wide and 10h inches
deep, inside measurements Gig. ~.
This may be made from egg-case ma
terial, or a packing box may be cut
down to these dimensions. Tongued-
and-grooved boards should be used II
possible, as the box must be light
proof. Leave a space IL inches high
and the width OF the box at the bot
tom Of the front Gig. /. P). Cut an
eyehole six inches wide by five inches
high In the top center of the front
Gig. 1, O). When cut az shown, the
hole IL about the right distance above
the candle to fit the height of the av-
erage man. Short men will prefer n
lower hole and tall men may require
higher box. Cover the egg open
ing with three pieces OF heavy black
cloth or oilcloth, making the center
piece overlap those at the sides Gig.
!, P). Each piece is seven or eight
inches wide and 1115 inches high. The
sidepleces are fastened to the case ut
the sides and top Of the egg opening I;
the centerpiece ut the top only.
Electrical Equipment.
Build stalls from thin lumber 3h
inches deep by 2la inches square
across the rear OF the bottom of the
box to hold the dry cells Gig. ., AZ.
This size box should hold six bat
terles, three for running the light and
three In reserve.
The strips above, and resting on the
tops of the cells Gig. =, F), are not
necessary unless It Is desired to pre-
vent the batteries from dropping out
II the case Is turned upside down.
These strips should be screwed TO the
back OF the cases so they may be cas-
lily removed when renewing the bat
terles.
The candlIng device proper is either
automatic or constant; that Is, It may
be made to give light continuously or
| only when an egg Is pressed lightly
ngainst It. Secure from any drug
store n new round tin ointment box
about two inches I'm diameter and
three-fOurths inch deep Gig. ., b.
Ream hole In the center OF the bot
tom just large enough TO hold firmly
the screw of small 3h-volt lamp,
such as Is used In little pocket fash
lamp.
The metal box, besides holding the
lamp, also Is needed TO convey current
TO the screw around the stem OF the
bulb. Therefore do not ream the hole
too large and do not use cloth or other
nonmetalllc packing TO hold II in
place around the stem OF the bulb.
Cut n hole in the cover OF the box
one inch In diameter, against which
the egg is held during candling.
To the lotion OF the box solder one
end OF n strip OF thin brass or steel
3Ia inches long by three-fourths inch
wide. This forms the spring which
brCuEg the contact when tbo ppndlp 10
used automatically Gig. 2. C).
TO the opposite side OF the bottom
solder a piece Of metal to form a lip
that passes under a button, which may
be turned 20 hold the box firmly
against the contacts when the candle
is TO give continuous light.
Make the mounting board for the
candle from piece OF wood six inches
long 21s inches vide and about one
