COMPLETE SPECIFICATION.
"An Improved Egg-shell Breaker."
We ISIDOR WOLF, of 87 Ritterstrasse, Berlin S., in the Empire of Germany,
and SIGMUND GALLUS, of Karolinenthal, Prague, Bohemia, in the Empire of
Austria, Manufacturers, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
The device forming the subject of this invention is what may be termed an egg-
guillotine, or, in other words, a device for breaking and removing part of the shells
of eggs; the advantage of this device over kindred arrangements hitherto known
being, that both its construction and operation are most simple, while it combines
the merit of durability with that of an extremely moderate cost.
The essential features of this improved egg-shell breaker are, firstly, an in-
wardly opening hollow ring, and, secondly, a pair of pivotted saw-blades, or
shears, embedded in, and guided by, the said ring; such blades being held apart
by spring pressure, while their free outwardly projecting ends are fitted with
handles.
The invention will be best understood by reference, to the accompanying draw-
ing, in which
Figure 1 is a sectional elevation of the egg-shell breaker, and
Figure 2, a vertical section of the same.
A is a hollow ring, open at its inner rim and enclosing the shears B, serrated
after the manner of saw-blades, one end of each of which turns upon a common;
pivot 1), while their opposite ends have extensions C, protruding through a slot E
in the ring A and fitted with handles F. The shear-blades are held apart by
means of a spring G wound around the pivot D. With a view to more convenient
operation, the ring A. may be provided with a finger-plate or shield,' such as A¹,
which may at the same time add to the decorative effect of the device, and have
the name of the firm, a number or other symbols marked upon it.
In breaking the shell of an egg, the shield A is grasped with the left hand, and
the handle F, with the right hand; the device is then placed on the top-end of
the egg and the handles are compressed.
The saw-teeth of the blades will then enter the egg-shell and cut off the top,
which may be finally severed from the egg by simply lifting off the cutting device.
A pin or stud H serves as a stop for the shear-extensions C.
The ring A may be constructed in many different ways; and the shears or
cutters, too, may vary extensively both in shape and in the means whereby they
are supported, without departing from the principle of the invention.
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:-
c
An egg-shell breaker, the main feature of which consists of serrated shears

(such as F) at the ends protruding through the ring.
