PROVISIONAL SPECIFICATION.
Improvements in Safety Pins and the like.
1, ARCHIBALD MORTON COLE of 280 Normanton Road, Derby in the County
of Derby, Cabinet Maker, do hereby declare the nature of this invention to be as
follows:-
My invention has reference to the more effective fastening of safety pins, curtain
pins, brooch pins, and the like, and the following description will refer more
particularly to safety pins although it will be readily understood that my invention
will apply equally well to other similar pins upon which considerable strain is likely
to be exerted.
As at present constructed there is considerable danger of the point of the pin
drawing out of the shield, or loop in which the said point fits, when any strain is
brought to bear upon the pin. To obviate this I form near the point thereof a
notch or notches or dove-tailed or other recesses which when the pin is fastened fit
into or engage corresponding projections, notches, sockets or tightened in portions
of the shield or loop so that in the case of the dovetail recesses the more strain
is put upon the pin, within reason, the tighter the point will wedge up in the
socket, shield or loop, and in the cases of notches or projections thereon
engaging corresponding recesses, the pin will also be found to be considerably
strengthened.
Dated this 31st day of May 1895.

COMPLETE SPECIFICATION.
Improvements in Safety Pins and the like.
I, ARCHIBALD MORTON COLE of 280 Normanton Road, Derby in the County
of Derby, Cabinet Maker, 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:--
My invention has reference to the more effective fastening of safety pins, curtain
pins, brooch pins and the like. and the following description will refer more
particularly to safety pins although it will be readily understood that my invention
will apply equally well to other similar pins upon which considerable strain is
likely to be exerted.
In describing my invention reference will be had to the accompanying sheet of
drawings upon which :-
Figure 1 is a perspective sketch of a safety pin constructed according to my
invention.
Figure 2 is a section on line a a of Figure 1.
Figure 3 is also a section on line a a of Figure 1 shewing another application of
my invention.
As at present constructed there is considerable danger of the point of the pin
drawing out of the shield or loop in which the said point fits, when any strain is

notch or notches B or dovetailed or other recesses which when the pin is fastened,
fit into or engage corresponding projections, notches, sockets or tightened in
portions of the shield or loop C preferably formed of an inverted V section at C¹ so
that the more strain there is put upon the pin, within reason, the tighter the point
will wedge up into the socket, shield or loop, and, in the case of projections D
thereon engaging corresponding recesses, the pin will also be found to be considerably
strengthened. Upon Figure 2 the recesses B are shewn in the thickness of the
wire and upon Figure 3 the projections D are shewn on the wire.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
-claim is :-
"
In a safety pin, curtain pin, brooch pin or the like the employment of notches,
recesses or projections near the point of same to engage and fasten or wedge into
suitably formed loops or shields preferably of an inverted V section, substantially
as and for the purposes described and illustrated.
