COMPLETE SPECIFICATION.
An Improved Button, and Means for Use in Attaching the same.
I, CARL FRIEDRICH REICHELT of 26 Luisenstrasse Berlin N.W. in the Empire
of Germany, 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 an improved button with means for use in the attachment
thereof, without sewing, to cloth or other fabric or material.
In the annexed drawing Fig. 1 is a section through the button. Fig. 2 shows in
plan a part thereof and Fig. 3 illustrates a needle to be used for perforating the
material and inserting the shank of the fixing plate of the button.
The button may comprise or be formed of the two plates D and C overlapped
and secured together at their edges. The plate C has a projection C¹ at the centre
of its under side the interior of which is conical and at the centre of this truncated
hollow conical projection is an orifice C2 for the passage of the shank A¹ of the
fixing plate A. Within the conical chamber formed by projection C¹ is a holdfast B
which may be made like a split ring or in two halves as shown in Fig. 2. The
inner face of the holdfast B is ribbed or corrugated in the form of circular, not
screw threaded, grooves; and the upper part of shank A' is provided with similar
grooves surrounding it. The outer face of the holdfast B is preferably conical
and its diameter is such that when it lies in the bottom of the cavity C₁ its interior
diameter is slightly less than the exterior diameter of the shank A¹. Above the
holdfast B between the plates D and C is an elastic or spring plate F and above
the centre of the latter the plate D may be slightly raised as at D'.
If the shank A¹ is pressed in through the opening C² it first pushes back the
holdfast B against the spring plate F, thus lifting the holdfast from the narrower
end of cavity C₁ and suffering it to expand or separate so that the shank A¹ enters
the holdfast. On releasing the plate A from pressure, the spring plate F pushes
down the holdfast B into the narrower part of the cone and causes it to be pressed
tightly about and engage the shark A, so that the latter cannot be withdrawn.
This is also assured when the plate F no longer presses upon the holdfast, owing to
the conical shape of the part C¹.
For convenience in passing the blunt ended shank A through any piece of stuff
to which the button is to be fastened, a needle such as E Fig. 3 may be employed.
This needle has in its base or wider end a recess for receiving the shank A¹ as
shown in the drawing. When the needle is pressed through the stuff the shank A¹
follows with it and the stuff passes tightly onto the plain part of the shank leaving
the ribbed part thereof projecting on the face of the stuff when the needle is
withdrawn. The button can then be pressed onto the shank as aforesaid.
Having now particularly described and ascertained the nature of this said
invention and in what manner the same is to be performed I declare that what
I claim is ;-
1. A button comprising a hollow body or button proper having in its under side
a conically hollow projection, a hold fast consisting of one or more distensible or
separable ring parts interiorly roughened by circular grooves or otherwise in said
projection, a spring plate for thrusting the holdfast into the projection, and a fixing

page_text: plate having a shank adapted to enter an orifice in said projection and be engaged
by said holdfast in the manner and for the purpose set forth.
2. A needle for the purpose described consisting of a spike having in its blunt
end an axially running cavity adapted to receive the shank of a fixing plate such
as A.
