COMPLETE SPECIFICATION.
An Improved Spring Safety Fastening for Scarf Pins and the like.
We, PAUL GOETZE of 8 Hornstrasse, Berlin, in the Empire of Germany,
Director, and RICHARD BLAESKE of 230 Friedrichstrasse, Berlin, in the Empire
of Germany, Jeweller, 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 :—
The usual method at present in use for fastening jewels, scarf pins, and other
objects of adornment to wearing apparel is by means of a needle or stem, which
however affords little security, as a loosening of the needle or stem frequently
results in the loss of the object which it serves to fasten.
Devices which have been invented to remedy these disadvantages are generally
too heavy and inconvenient to use.
Our present invention consists in improvements in the direction, both in the
matter of convenience and simplicity.
We will describe our invention with reference to a scarf pin, but it is obvious of
course that any jewellery required to be securely fastened to wearing apparel can
be provided with our improved spring fastening or clip.
In order that our invention may be better understood and more readily carried
into effect we will proceed to describe the drawing hereunto annexed.
Figure 1 represents an enlarged side view of the pin and its safety securing
device.
Figure 2 shows the pin n with an interlocking notch e.
Figure 3 is a vertical section through the pin and securing device.
Figure 4 is a general view of the device, and

figures of the drawing.
notch e.
n is the pin or stem. e is the notch previously referred to, provided for inter-
locking purposes. f is a spring the termination of which on the upper right hand
side, as shown in the drawing, penetrates and locks the pin by insertion into the
The clasp or spring which is made of a strip of metal bent to the shape
of a clasp, is formed with two flanges u, u¹ on the upper side turned inwards; one
of the flanges is somewhat lower and shorter than the other so as to allow one
flange to move over the other when the spring or clasp is pressed. Both flanges
are bent inwards at b.
When is pressed, that is, the spring, so as to cause the holes in the flanges u, u'
to come exactly opposite each other and the pin is now passed through these holes
and also the lower one 1, the elasticity of the loop causes the inner flange u to drop
into the notch e. The interlocking thus effected renders the liability to lose the
pin or other jewel improbable. The pin can only be withdrawn when the holes are
made to coincide again, that is to say, to come opposite each other in a vertical
line. The hole is made only sufficiently large to allow half of the pin's point to
pass through it; there is therefore locking top and bottom, as the pin cannot pass
downwards in consequence of the larger part of the pin being in the clasp, and
cannot pass upwards in consequence of the top of the clasp being interlocked with
the pin in the notch e.
The way
in which we carry out our invention is as follows.
The spring or clasp fis pressed so as to cause the flange u to leave the notch e in
the needle or pin.
When the pin n has been withdrawn and passed through the piece of cloth or
other material to which it is to be fixed, the clasp ƒ is again pressed so as to make

holes the flange u is moved into the notch e.
It is obvious that amongst other modifications of our invention that the notch e
in the pin n may be replaced by a hole perpendicular or nearly so to the axis of
the pin, and the flange u provided with a pin entering this hole (see Figure 5).
We prefer, however, the former arrangement of our invention to the latter.
The clasp can if desired be secured to the cloth or other article to which the
pin or jewel is supposed to be attached, by means of a small chain or in any other
desired manner.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
A pin securing device consisting of a spring clasp provided with side flanges,
which latter upon entering a notch or notches in the pin or the like, securely hold
the said pin to the garment or material to which the pin is attached, substantially
as and for the purposes herein set forth and as illustrated on the accompanying
drawing.
