PROVISIONAL SPECIFICATION.
Improvements in Cutting Machines for Opening Eggs.
I, KARL, HEDBERG, Mechanical Engineer, resident of Torpedo Station, in
the City of Newport, County of Newport, and State of Rhode Island, United
States of America, do hereby declare the nature of this invention to be as
follows:-
This invention relates to devices for cutting off the ends of eggs or the shells
thereof; and the object of the invention is to provide a device for this purpose,
which is simple in construction and operation, and by means of which the end of
an egg be broken off without breaking the rest of the shell.
The invention is fully described in the following specification:--
}
In the practice of my invention, I provide a frame which is oblong in form, and
provided with a circular opening and said frame is provided at one end with
projecting arms which connect with a tubular head or projection, provided with
guides or ways.
+
Mounted in the guides or ways, and adapted to slide therein, is a cutter,
provided with a cutting edge which may be segmental in form, convex, straight or
any preferred shape, and said cutting is provided with a stem or shank on which is
mounted a spring one end of which bears upon the cutter, and the other end of
which bears upon an inwardly directed annular shoulder, formed on the outer end of
the tubular head, through which the stem or shank, projects, and said stem or
shank is provided at its outer end with a button or head.
The frame, is provided with a curved cross piece, which forms a part thereof,
and part of the wall of the circular opening, and said cross piece is provided with
a semi-circular cavity or recess, through which passes the inner end of the stem or
shank, of the cutter, said stem or shank being provided with a head, with which the
cutter is connected and the central outer portion of the frame is provided with a
similar semi-circular cavity or recess.
I also provide a spring the inner ends of which are secured to the frame and
said spring is extended outwardly and is inwardly directed across the outer end of
the tubular extension or head, and is adapted to operate in connection with a notch
D'or recess, formed in the stem or shank, and to hold the same in the extended
.position, and the olject of the semi-circular cavity or recess, is to provide means
for drawing the cutter from the frame, which may be done by removing the button
or head.
:
The operation will be readily understood from the foregoing description. By
5 taking of the button or head and drawing the cutter out, the spring will operate in
connection with the notch or recess, to hold the cutter in this position, against
'the operation of the spring and the end of an egg being placed in the circular
opening, a slight pressure on the spring will release the spring, and the cutter
may be driven forward thereby, and the end of the egg cut off as will be readily
0 'understood.
The device herein described may be made of any desired metal or material, and
my invention is not limited to the exact form, construction and arrangement
"of parts herein described, and I therefore reserve the right to make all such

page_text: alterations therein, and modifications thereof, as fairly come within the scope of
the invention.

Improvements in Cutting Machines for Opening Eggs.
I, KARL HEDBERG, of Torpedo Station, City of Newport in the County of
Newport and State of Rhode Island, U.S. America, Mechanical Engineer, 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 :-
This invention relates to devices for cutting off the ends of eggs or shells
thereof; and the object of the invention is to provide a device for this purpose,
which is simple in construction and operation and by means of which the end of au
egg may be broken off without breaking the rest of the shell.
The invention is fully disclosed in the following specification, of which the
accompanying drawings form a part, in which :-
Fig. 1. is a plan view of my improvements parts thereof being shewn in
section.
Fig. 2. is a section on the line 2 2 of Fig. 1., and
Fig. 3. a. plan view of the frame.
In the practice of my invention, I provide a frame A. which is provided with a
circular opening B, and said frame is provided with projecting arms a, at one end
which connect with a tubular head or projection C. The frame is provided
with guides or ways D. Mounted in the guides D, and adapted to slide therein is
a cutter G provided with a cutting edge g which may be segmental in form,
convex, straight, or any preferred shape, and said cutter is provided with a stem K,
on which is mounted a spiral spring k one end of which bears upon the inwardly
directed annular shoulder L formed on the outer end of the tubular head C,
through which the stem K projects and said stem is provided at its outer end with
a button M and at its inner end with a tube to cover the spiral spring.
The frame A is provided with a cross-piece a' which forms a part thereof and
part of the wall of the circular opening B, and said cross-piece is provided with
cavities or recesses a through which passes the inner eud of the stem K of the
cutter G, said stem being provided with a head with which the cutter is
connected as shewn in Fig. 2. and the central outer portion of the frame A is
provided with a semi circular cavity or recess a*.
I also provide a spring O the inner ends of which are secured to the frame at o
and said spring is extended outwardly and is inwardly directed across the outer
end of the tubular extension or head C and is adapted to operate in connection
with a notch or recess P formed on the tube connection to the inner end of the
stem and to hold the cutter in the extended position.
The operation will be readily understood from the foregoing description when
taken in connection with the accompanying drawings.
By taking hold of the button M and drawing the cutter out the spring O will
operate in connection with the notch or recess P to hold the cutter in this position
against the operation of the spiral spring k and the end of an egg being placed in
the circular opening B, a slight pressure on the releasing spring O will release the
spiral spring and the cutter will be driven forward thereby and the end of the
egg cut off.

page_text: The device herein described may be of any desired metal or material and ny
invention is not limited to the exact form, construction and arrangement of parts
berein shewn and described, and I therefore reserve the right to make all such.
alterations therein, and modifications thereof, as fairly come within the scope of
the invention.
Having now particularly described and ascertained the nature of my said inven--
tion, and in what manner the same is to be performed, I declare that what I'
claim is :-
1. As a new and useful article of manufacture, an egg cutting machine con--
structed substantially as herein shewn and described, consisting of an oblong frame
having on one end a circular opening within which is a sliding cutter about the
projecting shank of which is fixed a coiled spring; projecting arms integral with.
said frame and supporting a tubular head provided with guides for said sliding
cutter; a curved cross-piece forming part of the wall of the circular opening in
said frame and provided with an opening for the passage of the cutter shank; a
corresponding opening in the frame to permit the withdrawal of the cutter from-
the frame and a spring arranged to hold the cutter shank out in normal position,.
all constructed and arranged as and for the purpose set forth.
