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 object of this invention is to produce an improved Safety Pin which will in a
great measure or entirely prevent the same from threading itself upon and thereby
becoming entangled with the fabric when in use, whereby the fabric is often torn or
disfigured in the endeavour to extract the pin.
The invention consists of the insertion of a small solid cylindrical or other shaped
piece of india-rubber or other suitably elastic material of a size proportionate to the
size of the pin within the circle or coil formed by the metal wire at the spring end of
the ordinary safety pin, the wire forming the pin being tightly coiled round the
middle part of the rubber or other suitably elastic material.
As a modification of my invention the coiled end of the ordinary safety pin may be
provided with a metal or other shield or shields for the purpose of ornamentation or
of more effectually preventing the threading of the fabric upon the pin, and the india-
rubber may be used or not as found convenient.
And in order that my invention may be more fully understood and carried into
practice I will now proceed to describe the same with reference to the accompanying
drawings in which similar letters are used to indicate corresponding parts in all the
figures.
Figure 1 is a view of the ordinary Safety pin.
Figure 2 shows the ordinary Safety pin threaded upon or entangled with the
fabric.
Figures 3, 4 and 5 show safety pins constructed according to my invention.
The india-rubber or other suitably elastic material A is inserted within or within
and about the circle or coil formed by the metal wire at the spring end B of the
ordinary Safety pin. The india-rubber or other suitably elastic material A may be of
any convenient shape and size, and may if desired for the more effectually preventing
the threading of the pin as before described, or for ornamentation be provided with a
metal or other shield of any convenient size or shape at the end thereof fixed to a pin

page_text: running through the centre of the said india rubber or other elastic material as shown
at C, D, Figure 3.
The wire E forming the pin is tightly coiled round the middle circumference of the
said india-rubber or other suitably elastic material so as to retain the same firmly in
position and preserving the necessary elasticity of the end B; or the metal or
other shield or shields C, D, may be fixed over or about the coil as shown in
Figure 5 for the purpose aforesaid either by soldering or brazing or in any
other suitable manner, and the india-rubber dispensed with if found convenient.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed 1 declare that what
I claim is
First. The insertion of a piece of india-rubber or other suitably elastic material A
in the spring end B of a safety pin substantially as and for the purpose hereinbefore
set forth and illustrated in Figure 4.
Second. The construction of a safety pin in which a piece of india rubber or other
suitably elastic material provided with a metal or other shield or shields is inserted in
the spring end B of the ordinary safety pin substantially as and for the purpose
hereinbefore set forth and illustrated in Figure 3.
Third. The construction of a Safety pin in which the spring end B is covered or
partly covered with a metal or other shield or shields substantially as and for
the purpose hereinbefore set forth and illustrated in Figure 5.
