IMPROVE- MENTS IN THE CONSTRUCTION AND MANUFACTURE OF METALLIC BOXES OR CASES
Year: 1886

page_text: We, ERNST AUGUST JAHNCKE, Manufacturer, and HENRY WILLIAM HERBST,
Engineer, both of Canonbury Works, Dorset Street, Essex Road, Islington in the
County of Middlesex, do hereby declare the nature of our invention for IMPROVE-
MENTS IN THE CONSTRUCTION AND MANUFACTURE OF METALLIC BOXES OR CASES,
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
Our improvements consist in the manufacture and construction of a metallic box
for holding cigarettes or other articles provided with a rim forming a frame around
the abutment of the box thus making the box a more substantial article. For the
opening of the box a projection is formed on the front of the box, which we will
call the thumb piece.
The novelty of this is the peculiar way in which we are enabled to produce these
improvements, thus offering a great advantage in the manufacture.
An arrangement is fitted inside the box by which cigarettes or similar articles
are held and by which they may be raised up when the box is open so that the
cigarettes or other contents can be taken out with greater convenience.
"
We shall now describe the improvements more particularly with reference to
the accompanying drawings.
The box consists of two shells which are connected by a hinge.
The one shell is formed with the rim or frame around its edge.
A metal blank is cut to the required shape, see
66
Figure "1," and dished with
the portion which will form the rim thrown partly outward as shown at "a"
Figure "2" Section Figures "2 A " and " 2 B."
The rim is then drawn in and a rebate or set off is formed inside the rim against
which the other shell of the box abuts as shown at "a" Figure "3" and Section
Figures "3 A" and "3B" and Section Figure "12"; this being done in the
aforesaid manner, has the advantage that the previously prepared surface of the
metal is not damaged whilst under treatment.
The object of setting the rim or frame outward in the aforesaid manner is to
greatly facilitate the manufacture and at the same time to make the article more
substantial than in the ordinary way.

page_text: A nib “b” is formed in front of the rim acting as the catch or part of the lock
of the box.
The other shell is formed with the thumb piece (in the manner as hereafter
described) on to which pressure is applied when the box is to be opened.
A metal blank is cut to the required shape as shown in Figure "4."
It is then dished and the portion which is intended for the thumb piece is set
outward in such a manner that by this action the thumb piece is partly formed as
shown at "c" Figure "5" and Section Figures "5 A" and "5 B." The thumb
piece is then completed on the shell by pressing the front portion of the partly
formed thumb piece inward (at the same time forming the nib "d") as shown
at "c" and "d" Figure "6" and Section Figure "6A." The hinge by which the
two shells are connected is formed in the usual way.
"
The catch or nib "b" and "d" on the two shells form the lock of the box.
When the box is to be opened pressure is applied on to the thumb piece "c"
and by this the catch "d" is released from the catch "b" of the other shell and
thus allows the box to open.
In the manner in which the aforesaid thumb piece is produced no strain is
applied to the metal thus enabling us to form the said thumb piece in the same
blank which forms the shell without injuring the metal, thereby offering a great
advantage in the manufacture as well as neatness of the article.
The inside arrangement consists of two pockets, one in each shell and pivoted
therein. The same are formed in the following manner.
A blank is cut in sheet metal to the required form with the portion "e"
and "e1" slit as shown in Figure "7." The sides "f" and "f1" are curved up and
the sides "g" and "g 1" are turned up to a right angle as shown in Figure "8."
The outward portion of the slit parts "e" and "el" are curled over similar to
an ordinary hinge and the portion "h" is stamped up.
The middle portion is then bent as shown in Figure "9." Then the corner "i
is closed down, thus completing the pocket as shown in Figure "10," side view
Figure "10 A" and end view Figure "10 B” and allowing it a little spring in the
two ends.
Of this two are made. We now place one in each shell as shown in Figure " 11."
Holes are provided in the sides of the shells which correspond with the tubular
opening in the curled over parts "e" of the pockets. Through these holes small
pins are inserted and driven in to the aforesaid tubular parts "e" in the pockets.
By these pins the pockets are pivoted into the shells. Now when the box is opened
and pressure applied on the lower edge of the indentation "h" the pocket will rise
up bringing with it the contents as shown by the pocket marked "K" Figure " 11."
When the box is to be closed the raised pocket or pockets are dropped in to the
shell and the box closed in the ordinary way, thus bringing the two surfaces of the
pockets together, and by this the spring (produced in the pockets) is compressed
thus gripping and holding the contents firmly as shown in Figure " 12."
The inside arrangement or pockets can be omitted when desired.

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 :-
1. The rim or frame around the abutment substantially as hereinbefore described
and illustrated in Figures 1, 2, 3, 2 A, 2 B, 3 A, and 3 B.
2. The mode of manufacture or production of the said rim or frame substantially
as hereinbefore described and illustrated.
3. The mode of manufacture or production of the thumb piece substantially as
herein before described and illustrated in Figures 4, 5, 5 A, 5 B, 6, 6 A.
4. The inside rising pocket arrangement substantially as herein before described
and illustrated in Figures 7, 8, 9, 10, 11, and 12, and their respective sections in
the accompanying drawing.
