page_text: I, OSKAR KOENIG, Brewer, of Lindenberg, Allgäu, Bavaria, in the Empire of
Germany, do hereby declare the nature of this invention to be as follows:-
Safety-pins as hitherto constructed have the disadvantage of being liable to
unfasten when in use and in consequence frequently become lost, such loss is
especially unpleasant in case of the pins being attached to jewellery or the like.
The object of this invention is to so construct safety pins as to render the
unfastening of such pins an impossibility without human interference and thus
prevent the loss thereof.
To this end I form in addition to the ordinary hook for engaging with the end of
the pin an additional hook carried by an arm and arranged symmetrically to, and
bearing against the ordinary hook; thus forming a duplex hook adapted to yield
enough to allow of the insertion of the pin between the two hooks in order to cause
it to engage in one or the other thereof. The arrangement here adopted is such
that the pin on becoming accidentally disengaged from its hook must necessarily
slip into the other hook and cannot by itself become unfastened.
For unfastening the safety-pin it is only required to disengage the pin from its
hook and place the point between the inner curved ends of the hooks and then
force the latter slightly apart to release the pin and allow it being withdrawn.

I, OSKAR KOENIG, of Lidenberg, Allgäu, Bavaria, in the Empire of Germany,
Brewer, 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 :-
Safety-pins as hitherto constructed have the disadvantage of being liable to unfasten
when in use and in consequence frequently become lost. Such loss is especially
unpleasant when the pins are attached to jewellery or the like.
The object of this invention is to construct safety-pins so as to render the unfastening
of such pins an impossibility without personal interference and thus prevent their
loss.
To this end in addition to the ordinary hook for éngaging with the end of the pin
I form an additional hook carried on a separate wire and arranged symmetrically to

page_text: and bearing against the ordinary hook; thus forming a duplex hook adapted to yield
enough to allow the insertion of the pin between the two hooks in order to cause it to
engage in one or the other thereof. The arrangement here adopted is such that the
pin on becoming accidentally disengaged from one hook must necessarily slip into
the other hook and cannot become accidentally unfastened.
For unfastening the safety-pin it is only required to disengage the pin from its
hook and place the point between the inner curved ends of the hooks and then force
the latter slightly apart to release the pin and allow it to be withdrawn.
In the accompanying drawings:-
Fig. 1, shows, a view in perspective of my improved safety-pin, with pin engaged in
one of the hooks.
Fig. 2, shows a side view of Fig. 1.
Fig. 3, shows an end view of the double hook.
a is the main wire of the safety-pin formed at the end with a hook as shown.
b is the additional wire with the second similar hook, the two wires being connected
by the fixed sleeve c.
n is the pin which engages with the hooks.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
1. In a safety-pin, the additional wire, with hook as shown, and sleeve, as herein
described and set forth.
2. The improved safety-pin which cannot open without being personally operated,
as herein described and set forth.
