COMPLETE SPECIFICATION.
Improvements in Egg Openers.
I, WILLIAM THOMPSON, of Ivy Cottage, Stratford-upon-Avon, in the County of
Warwick, Architect and Surveyor, 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:―
My invention has for its object improvements in egg openers and is for the
purpose of facilitating the removal of the top of an egg whereby the present
troublesome method is abolished.
In carrying my invention into effect I make use of a guard made of metal, of
cone form having a circular hole in the top of suitable diameter to admit that
portion of the top of an egg it is desired to remove, to protect the brittle shell
of an egg during the process of removing the top, to the underside of the top of
the guard I place a washer shaped india-rubber band which is held in position
by a wood ring secured to the guard by screws, two holes are made in the guard
for the convenience of holding the same, conjointly with the guard I use a knife
having a serrated of file-like cutting edge.
In order that my invention may be more readily understood and carried into
effect I append hereunto a sheet of drawings upon which I have illustrated my
invention.
Figure 1, is an elevation of my invention. A, is an egg cup. B, the egg
showing the portion of its end to be removed. C, metal guard. c, is one of the
two holes for the convenience of holding the guard during the process of cutting
the top of an egg off. b, b, screws for securing wood ring to the guard.
Figure 2, is a section. A, is an egg cup, B, the egg. C, C, metal guard.
D, D, the wood ring secured to guard by screws, E,E, india-rubber band.
Figure 3, shows a knife of a suitable form for use in combination with the
metal guard.
To cut the top of an egg off, place the egg in an egg cup, take the guard in
one hand placing the forefinger and thumb on the holes formed in the guard and
hold the guard on the egg, that portion of the top of an egg to be removed pro-
jecting through the hole in the guard, with the knife held in the other hand
resting the blade on the top of the guard cut slowly at first with a gentle pressure
against the egg until the knife has penetrated the shell and then with a quick
motion cut the top of egg off, the two holes in the guard permit of the finger and
thumb holding firmly the egg cup so that neither the egg, guard or cup are
liable to move during the process of removing the top of an egg.
The circular hole in the top of guards are made to vary in diameter to suit eggs
of different size the object being to remove the top of an egg without disturbing
the yelk.
I do not limit myself to the shape or form that may be given to the knife so
long as it achieves the object in view.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, but take notice I do
not claim a knife having a serrated or file-like cutting edge but that which I
claim is new. I declare that what I claim is:-
Improvements in egg openers, consisting of a guard as herein before described
in combination with a knife having a serrated or file-like cutting edge, sub-
stantially as and for the purpose herein set forth and shown.
Dated this 24th day of July 1899.
