A Device for Separating the Yolk and White of Eggs. .
ALBERT LAZARUS GUITERMAN, 35, Aldermanbury, London, E.C., Merchant, do
hereby declare the nature of this invention to be as follows:-
I make a basin or vessel of porcelain or other suitable material but porcelain
preferred. This basin or vessel has one or more openings at the side or bottom,
but side preferred. These openings may be round or any other shape most con-
venient for the purpose. I break the egg or eggs into the basin, and allow the white
of the egg to escape through the opening or openings and retain the yolk of the egg
in the basin which can be emptied as desired.
A Device for Separating the Yolk and White of Eggs.
I, ALBERT LAZARUS GUITERMAN, of No. 35, Aldermanbury, in the County of
London, Merchant, do hereby declare the nature of this invention (a communication
to me from Herbert Mortimer Guiterman, of United States of America) and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to a device for separating the yolk and white of eggs.
For many purposes in cookery and otherwise it is required to separate the yolk
cleanly from the white in order that each may be prepared separately or for the
purpose of excluding one of such elements entirely from the preparation, and that
in most cases it is desirable that the yolk shall not be broken during the separation
of it from the white.
The most usual method of effecting the separation is to first crack the shell
against the vessel in which it is to be prepared and then cautiously open it out
to an extent calculated to be just sufficient to allow the yolk to slip out alone, and
after its exit, to turn upwards or close the two halves of the shell to prevent the
white from following the yolk.
Now, owing to the tenacity with which the yolk and white adhere to one another,
and the suddenness with which the egg opens, it requires considerable practice
and skill to effect the complete separation of the yolk from the white and especially

page_text: without breaking the yolk which latter as above stated is often an essential con-
dition, and even an adept cannot make sure of preventing the white from slipping
out with the yolk. Sometimes the method of separation adapted is to first drop
yolk and white together into the vessel and then attempt to separate them by
pouring the white away, but this also requires considerable skill, time and practice
and does not at best effect the complete separation as desired owing to there being
practically no control over such slippery contents.
In order to obviate the above mentioned difficulty I have invented the device,
the subject of this application, which quickly and perfectly effects the separation
of the yolk from the white of eggs, and is so simple that anyone even a child with-
out any previous practice can operate it successfully and without fail.
I will now describe my invention with reference to the accompanying sheet of
drawings illustrating the same, and in which;
-
Figure 1 is a central vertical section through my egg separator device.
Figure 2 shews the separator in elevation, and
Figure 3 illustrates the separator in perspective in the act of separating the yolk
from the white.
According to my invention I make a basin or vessel a of porcelain or any other
suitable material, and in the bottom or side thereof I cut or form one or more
apertures of any shape but preferably in the form of elongated openings or slits
such as b, the device is then complete.
The method of using the separator is as follows:
The egg or eggs are first broken and their contents let fall whole into the separ
ator or basin, it is then only necessary to tilt the separator sufficiently to allow the
white to flow out of the aperture b, when the yolk by coming in contact with the
edge of the said aperture will thereby be held back, and thus prevented from
escaping along with the white, and retained in the vessel as desired.
In this manner any number of unbroken yolks may be separated from their
whites quite cleanly and with the greatest facility by anyone.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. A device for separating the yolk of an egg from the white, consisting of a
small basin or similar containing vessel having one or more apertures or slits in
the side or sides thereof.
2. A device for separating the yolk of an egg from the white, consisting of a
small basin or similar containing vessel having one or more apertures or slits in
the bottom thereof.
