An Improved Process for Treating Eggs.
We, DAVID DOUGLAS WILSON and JOHN A. WILSON, both of the town of Sea-
forth, in the County of Huron, Province of Ontario and Dominion of Canada,
Egg Packers and Exporters, 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:
Our invention relates to an improved process for treating eggs, the object being
to treat eggs with a preserving solution and then restore the eggs to their natural
appearance.

Under the old system of preserving eggs, by the use of lime water, the eggs
were placed in the preserving fluid and left either uncovered, or covered by plac-
ing cloths on top of them and then placing a quantity of thick slaked lime on
top of the cloths which in both instances caused the eggs to become thickly coated
with particles of lime. After removing the eggs from the preserving fluid, it has
been the practice heretofore, to merely wash them with clean water alone. But
in so doing, the particles of lime adhering to the shell were not dissolved, thus
leaving them with an unnatural appearance and condition. Added to this is the
well known disadvantage that eggs with particles of lime left on the shells are
thereby rendered air tight and will not boil without bursting.
We propose covering the preserving fluid in the vats or tanks where the eggs
are placed, with deodorized oil to exclude the air from the eggs and preserving
fluid, which prevents to a great extent the formation and deposit of lime particles
on the shell, thus tending to keep the same sweet and in their natural conditions.
The eggs are then washed in a solution of hydro-chloric, acetic, sulphuric acid,
glycerine or equivalent chemical which will dissolve lime, and water, in sub-
stantially the following manner: Upon removing the eggs from the preserving
fluid in the vats, they are first thoroughly rinsed with clean water so as to remove
as much as possible of the preserving fluid. The eggs are then immersed in the
acid or other chemical solution long enough to dissolve any lime or other deposits
upon the shells. Then they are again immersed and rinsed in clean water for
the purpose of removing the acid or other chemical solution and finally the eggs
are thoroughly air dried.
The result is that the shells will be almost, if not quite, restored to their
natural bloom and appearance. Also the difficulty of the eggs bursting when
boiled, hitherto alluded to, is very greatly removed. The result is that the com-
mercial value of the eggs is very much increased.
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:-
1. The herein described process for treating eggs consisting in covering over
the fluid in which the eggs are pickled, with oil to exclude the air.
2. The herein described process for treating eggs consisting in washing them
after they have been through the pickling or preserving process, with a solution

shells.
3. The herein described process for treating eggs consisting in washing them
after they have been through the pickling or preserving process in a solution
of hydro-chloric acid and water.
4. The herein described process of treating eggs consisting in covering the
fluid in which the eggs are pickled or preserved, with oil, to exclude the air
and finally washing the eggs in a solution of water and other chemical which will
remove any extraneous particles adhering to the egg shell and restoring the egg
to its natural appearance and condition.
5. The herein described process for treating eggs. consisting in removing the
eggs from the preserving or pickling fluid, thoroughly rinsing them in clean
water to remove as much as possible of the preserving fluid, then immersing
them in acid or other chemical solution long enough to dissolve the adhering
lime or other deposits on the shell, then immersing and rinsing the eggs again
in clean water for the purpose of removing the acid or other chemical solution,
and finally air drying the eggs thoroughly.
