Improvements in or connected with Buttons.
I, FRIEDRICII WILHELM LANGE, of Lüdenscheid, in the Kingdom of Prussia, in
the Empire of Germany, Manufacturer, trading under the Firm of Gebrüder
Lange, 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 relates to that class of buttons, which may be called mortice-
buttons, consisting of two separate parts, the upper part, or button proper, and the
lower or foot-part, the said two parts being united by a pin or shank traversing
the cloth or fabrics and engaging the opposite part of the button, thus avoiding
all sewing and thread in fastening the button. Buttons of this kind, in general,
are known. The particular and improved construction of this kind, to which the
present invention relates, is illustrated by the accompanying drawings, in which
Figure 1 is a sectional elevation of the button shown in the position, in which the
connecting pin is being introduced; Figure 2 is a corresponding view shown in
the position in which the connecting pin has been introduced and locked in its
central position and Figure 3 is a plan or top-view of the button.
The upper part or button proper consists of two halves A and B, preferably of
sheet-metal, so constructed and combined as to slide or turn within each other,
without being separated. To admit of such a sliding or turning motion, the lower
half B of the button overlaps the edge of the upper half A; or the two halves A,
and B, may engage in any similar or other manner. Each of the said two
halves A, and B is provided in its central portion with a slot a, and b, extending
from the centre and having at its outer end an enlarged portion, as clearly shown
in Figure 3. The foot-plate or base D of the button carries a pin or shank C, with
slightly enlarged head c, the said head being so proportioned as to pass through
the enlarged portion of the slots a, and b, but not through the slots at their inner
or central part. The diameter of pin C is however so proportioned as to pass
through the said slots. The upper half A, of the button proper may conveniently
be provided with holes as e or other convenient means to allow of the introduction
of a key or other tool for turning the said upper half relatively to the lower half B.
For combining the foot or base of the button with the button proper, as shown
in Figure 2, the pin C is first pierced through the cloth or fabrics and the two
halves A and B are so turned relatively to each other, as to make the two slots a,
and b, register with each other, Figure 1. The head c of pin C, may then be readily
passed through the slots and the pin C shifted into its central position, as shown in
Figure 2. The upper half A of the button is then turned to its opposite position
as indicated by dotted lines in Figure 3, and the head c of pin C cannot be removed
from the slots, until the half A is again turned into the position to register its slot a
with the slot b of the other half B, as in Figure 1.
The button constructed according to this invention not only holds safe and sure
during use, but it may be separated and removed from the garment or fabrics to
which the button had been fitted, in order to be again used. Other buttons of the
mortice-system must be entirely destroyed to remove them and cannot therefore be
emplowed again

page_text: Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is:-
-
In a button consisting of a base or foot-plate carrying a pin or shank and a
button proper, through which said pin is to be passed and locked, the construction,
substantially as described, of the said button proper, in two halves arranged to
turn or slide within each other, each of said halves having a slot extending from
the centre and being enlarged at its outer end, to allow of the head of the base-pin
being introduced and withdrawn, when the two slots are adjusted to register with
each other.
