Complete Specification Accepted, 28th Sept., 1888
I, OTTO BÖTTCHER of Nauenerstrasse, Potsdam, in the German Empire, Merchant
do hereby declare the nature of this invention to be as follows:-
This invention relates to a safety pin which may be used simply as an ordinary
fastening pin or it may be applied to brooches, clasps and other objects for fixing to
wearing apparel.
It consists of the pin proper soldered into one end of a small metal tube bent round
so that the pin and tube part has the form of a staple, the tubular part of which may
be slid to and fro along a wire or smaller internal tube so as to open or fasten the
pin, in which latter position a spring may act to keep it closed. The end of the
inner wire or tube is also bent round, the end of the pin when fastened entering it
and is thus kept guarded. The outer pin and tube part is carried so as to slide in
bearings and the wire or internal tube is fixed in similar bearings, these being mounted
on a thin plate or on such objects as aforesaid. The wire or internal tube has a small
tooth which fixes the pin in the fastened position by taking into a slot in the outer
tube. The travel of this latter in the open direction is limited by a collar on the
end of the same coming against the bearing in which it slides.

An Improved Safety Pin, Applicable also as a Brooch or like Pin.
I, OTTO BÖTTCHER of Nauenerstrasse, Potsdam, in the German Empire, Merchant,
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 a safety pin which may be used as an ordinary fastening
pin or as a pin for brooches and like objects for fixing these to wearing apparel.
The accompanying drawing shews the same mounted on a plate by which it may
be attached to the frame of a brooch or other article of adornment, Figs. 1, 2, and 3
being respectively a side shut view, a side open view and an end view.
a is the pin proper soldered, brazed or otherwise fixed into one end of a metal tube b
bent round so that the pin and tube together present the form of a staple; e is a slot.
in one end of the tube b which allows that part of the same to spring open when
necessary; d is an aperture at the slotted part of the tube; h a wire or tube of a size
to slide to and fro in so as to shut or open the pin. In the former case the tube bis
slid over the internal part and when the slotted part comes against the projecting 1
catch e it opens and remains so until said catch engages in aperture d when it closes
again fixing the pin in the closed position, the end of the pin proper being entered
within the end of wire or tube and thus guarded. The pin a and tube / are
arranged to slide in guide bracket whilst the part h is held fixed in a similar bracket g
both brackets being fixed to the plate. The tube is provided at its slotted end with
a collar k for limiting its outward travel and preventing a separation of the tube from
the part, by the said collar coming against the bracket fin which the tube b slides.
The brackets fand g are so formed and fixed to the plate that the orifices for the tube b
and longer arm of part are quite close thereto, whilst those for the shorter arm of h
and for the pin proper are sufficiently distant therefrom to allow room for the
material of the wearing apparel to be fastened.
tg,
When used as an ordinary fastening pin, the brackets f and g are done away with
and an angular cross section given to the slide surfaces of b and h to insure the
entrance of the pin point into the orifice or recess at i.
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 1
claim is :
1. A safety pin consisting of two bent tubes b, h, or of one bent tube and one bent
wire the one sliding upon the other the tube h carrying the nin nraner which when

page_text: in the closed position projects with its point into the bore or into a recess of h
substantially as described and shewn.
2. In a safety pin of the kind referred. to the arrangement of a projecting catch e
on the internal tube or wire h, and aperture d in tube b in which the catch e enters
upon the closing of the pin so as to insure the closure thereof, in combination with a
slot at the end of tube 6 to allow of the catch e entering said tube and becoming
fixed therein substantially as described and shewn.
