IMPROVEMENTS IN APPARATUS FOR OPENING AND HOLDING EGGS
Year: 1884

page_text: COMPLETE SPECIFICATION.
We, CHARLES GUYARD, of N° 70, rue Saint Maur, Paris, France, fitter, and
LÉON GARNIER, of N° 70, rue Saint Maur, Paris, France, Modeller, do hereby
declare the nature of said Invention for "IMPROVEMENTS IN APPARATUS FOR
OPENING AND HOLDING EGGS," and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement:-
An apparatus for opening eggs according to this invention has a knife or tool'
capable of being forced or intruded through the shell, and then of being rotated or
moved around the egg so as to divide the egg into two parts. This knife is
provided with a handle for its manipulation and is pivotted or otherwise connected,
to a ring, annular plate, or washer carried by a ring, plate, collar, or ferrule upon
which it turns. The above described apparatus may be combined with an egg cup
mounted upon a spring to bring the egg into the proper position with relation to
the knife or tool, or it may be independent, and when used be placed over the egg
and then removed.
Referring to the accompanying sheet of drawings Figs. 1 and 2 represent in
vertical section and in plan an improved apparatus for opening and holding eggs
according to this invention. The egg A is inserted into the cup or support B and
then the annular cover C is placed over it and secured by its rabitted edge and the
clasp E to the rim of the stand or foot D. The spring F forces the egg gently
against the interior edge of the conical part of the cover, around which the ring or
washer G can turn. This latter carries a triangular pointed knife or tool H,
pivotted at I. To effect the opening of the egg thus placed in position, the stand
or foot is held by the left hand, while at the same time a finger is laid upon the
ring or washer G to prevent its rotation. At the same time the knife or tool H is
turned in such a way as to cause it to pierce the shell, and to penetrate with its
cutting edges into the interior of the egg.
The pressure is then removed from the ring or washer G, which is rotated in the
direction of the arrow f, carrying with it the knife or tool H resting against the .
stop i, and thus the upper part of the egg is neatly divided from the lower part.
After the knife or tool has been turned into the position shewn in dotted lines
the egg can be eaten from the apparatus.
When it is desired that the egg should be eaten from an egg cup, and the
improved apparatus should be used solely for opening it, it is then constructed as

page_text: shewn in section in Fig. 3, and in plan in Fig. 4. The ferrule or collar D' is placed
and lightly held over the egg. The knife or tool H¹ is rotated on its pivot until it
comes against the stop i, and then it is carried round the egg as described above.
The egg being divided the ferrule or collar D¹ is removed, and the egg eaten from
the cup or stand in which it was opened or from another as desired.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
1. In an apparatus for opening eggs the combination of a ring, annular plate or
washer surrounding the egg, and a knife or tool capable of being forced or intruded
through the shell, and then of being rotated or moved around the egg, substantially
as described.
2. The combination with an instrument for opening eggs, such as referred to in
the preceding claim, of a support or stand acting as a cup to hold the egg while
being eaten.
3. The improved apparatus for opening eggs substantially as described with
reference to Figs. 1 and 2 or to Figs. 3 and 4 of the drawings.
