COMPLETE SPECIFICATION.
An Improved Button.
I, CURT LEUCKART, of Schutzen-strasse No. 10, Leipzig, Germany, Clock-
maker, 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 has for its object to provide an improved button which, while
being applicable to either ladies' or gentlemen's garments, can be readily attached
thereto by means of suitable metal pins or catches. The button differs from those
hitherto in use in that it can also be easily detached from the garment whenever
desired.
The construction of the pins or catches is such that the material of which the
garment is made remains uninjured when the button is detached even although it
may have been some time in use. A further advantage of the invention is that
the head or visible part of the button can be made of any suitable material similar
to that of the ordinary sewn buttons hitherto in use.
And in order that my said invention may be properly understood I have hereunto
appended an explanatory sheet of drawings, whereon :-
Fig. 1 shows in side view and in plan the base part of the button.
Fig. 2 shows in side view and plan the head or upper part of the button.
Fig. 3 shows a button fixed to a garment.
The base or lower part a of the button is made of any suitable material and is
provided with one or more points b which may be of round, rectangular, or of other
suitable shape in section.
As shown at Fig. 1 the points are sharpened so as to easily penetrate the
material of which the garment is composed and they are also made with nicks b¹
on either their inner or outer sides.
The head a¹ of the button, as shown at Fig. 2, is of a special construction being
punched or otherwise formed from a piece of metal to which is secured, in any
suitable manner, a piece of horn, bone, fabric, or other suitable substance or
material e, so as to constitute the outer surface of the button. At or about the
centre of the metal head a' two holes c, corresponding to the points b, are made
and into these holes, when the parts of the button are being fitted together, the
points are inserted. The underside of the head a¹ is recessed and into this
recessed part a spring d is fitted. This spring is bent over or shaped so that its
free ends or legs can enter the nicks of the points b when the latter are fitted
into the holes c. The spring d can be soldered to the head a', or, as shown at
Fig. 2, the bent portions of the spring may be made to project slightly through
the wall of the recess and the spring be held in position by means of a small
tongue d' struck up from the metal of the head. This method of fixing does not
impair the elasticity of the spring. There is also formed on the part a', by means
of a punch or in other manner, a loop under which the ends of the legs of the
spring pass as shown at Fig. 2. The ends are within the recessed part of the
button so that they cannot tear the fabric.
When the parts of the button are fitted together, as shown at Fig. 3, the ends
or legs of the spring d enter the nicks of the points band thus firmly lock the
two parts together. When it is desired to remove the button or shift it to another
part of the garment, the ends of the spring d are pressed together from the outside

by any pointed article, such as a needle for instance, and their hold on the
notches relaxed. The head of the button can now be removed without difficulty
from the points and thereafter the lower part a of the button can be withdrawn
from the fabric.
In the underside of the part e of the button small holes or recesses may be
formed as indicated at Fig. 3, to admit the ends of the points b when the parts of
the button are secured together.
If desired instead of two points 6 three or any other number may be used but in
the event of a single point being found sufficient it must be provided with a circular
groove to receive the spring d.
By providing two or more points there is less likelihood of the fabric being torn
when a hard pull is exerted on the button.
Instead of using the form of spring shown at Fig. 2 a plate spring or a single
spring flattened on both sides may be used.
A special advantage of this button is that it can be readily inserted in place or
removed without the assistance of a tailor.
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
consider novel and desire to claim is :-
A button made in two parts one part having one or more points which can be
fitted into the other part and locked in place by means of a spring arrangement,
substantially as herein before set forth.
