Improvements in Apparatus for Testing Eggs.
We, JAMES LYONS, ALFRED LYONS, and GEORGE LYONS, trading as Lyons
Brothers, of 18 and 20, Oak Street, Shudehill, Manchester, in the County of
Lancaster, Provision Merchants, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in that class of apparatus for testing"
eggs wherein the eggs to be tested as to freshness are placed upon and supported
by annularly grooved rollers employed over a source of light or reflection, the
object of the present invention being to so arrange the said rollers and source
of light or reflection as to provide an apparatus for testing eggs suitable for use
in the retail egg trade, or for private use.
To this end we form a box or chamber the top of which is open and over.
which we employ a series of annularly grooved rollers each two adjacent grooves
of such rollers forming a bottom-less receptacle to hold the eggs to be tested.
The said rollers do not travel longitudinally, but are suitably geared up, say
by means of pulleys and cords or bands and one of the same adapted to be
rotated by hand so as to be able to rotate the whole series of rollers and all
the eggs thereon simultaneously.
The bottom of the said box or chamber we furnish preferably with a reflector,
say a mirror and the side we form with an opening closed by a lid. The eggs
placed onto the said rollers are reflected upon the said mirror and by opening
the said lid and looking through the respective opening the bad eggs can be
readily detected by the said mirror.

Improvements in Apparatus for Testing Eggs.
We, JAMES LYONS, ALFRED LYONS, and GEORGE LYONS, trading as Lyons
Brothers, of 18 and 20, Oak Street, Shudehill, Manchester, in the County of
Lancaster, Provision Merchants, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:
This invention relates to improvements in that class of apparatus for testing
eggs wherein the eggs to be tested as to freshness are placed upon and supported
by annularly grooved rollers employed over a source of light or reflection, the

page_text: object of the present invention being to so arrange the said rollers and source
of light or reflection as to provide an apparatus for testing eggs suitable for use
in the retail egg trade or for private use.
And in order that our invention may be more fully understood we have
caused to be appended hereunto one sheet of drawings marked with letters of
reference indicating like parts in the various figures.
Fig. 1 is a front view, Fig. 2 a plan, Fig. 3 a vertical section at line A-A
of Fig. 2, and Fig. 4 an end view partly in section.
In carrying out our invention and referring to the figures generally, we form
a box or chamber a the top of which is open and over which we
of annularly grooved rollers beach two adjacent grooves of such rollers forming
employ a series
a bottomless receptacle e to hold the eggs to be tested.
The said rollers do not travel longitudinally, but are mounted in bearings c
secured to the sides of the box or chamber and are suitably geared up, say
by means of pulleys and cords or bands.
One of the said rollers is adapted to be rotated by hand, so as to be able to
rotate the whole series of rollers and turn all the eggs thereon simultaneously.
The bottom of the said box or chamber we furnish preferably with a reflector,
say a mirror and one side we form at the top with an opening k closed by a
lid.
The eggs placed onto the said rollers are reflected upon the said mirror i and
by opening the said lid the bad eggs can be readily detected by the said
mirror.
The said reflector may however be dispensed with and a light employed in
the said box or chamber, in which case the eggs are examined from above.
In order to darken the interior of the box or chamber as much as possible
strips m shaped to fit into grooves of the rollers are secured to each end of the
said box or chamber we well as straight strips n, see Figs. 2 & 4, extending below
across the thick part of the said rollers, or any other suitable means may be
employed for that purpose.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that
what we claim is:-
1st. An apparatus for testing eggs, consisting of a dark box or chamber
furnished with a source of light or reflection and over the latter with a series
of annularly grooved laterally stationary rollers adapted to be jointly rotated
and turn the eggs to be tested, all substantially as set forth.
2nd. In an apparatus for testing eggs, having a series of annularly grooved
laterally stationary rollers capable of rotation only and a reflector below the
same, the box or chamber formed at the side with an opening through
which the eggs can be seen on the reflector, all substantially as set forth.
