PROVISIONAL SPECIFICATION.
An Improved Safety Pin.
I, SAMUEL JOSEPH NICKLIN, trading as J. Nicklin & Co., of Great Charles
Street, in the City of Birmingham, Manufacturer, do hereby declare the nature of
this invention to be as follows:-
This invention consists of the improved safety pin herein described which is one
of that kind in which a shield is fixed to one arm and the pointed arm is arranged
to enter the shield from either side of the pin and when the pin is closed the
pointed arm can be sprung out of the arch or trough of the shield from either side.
Within the shield of the safety pin there is a central rib or partition which
prevents the pointed arm of the pin passing straight through the shield without
entering the arch or trough and thus ensuring the said pointed arm entering the
arch of the shield where it lies when the safety pin is closed. At the present time
there are various methods of forming the said partition in the shield but the method
which I adopt of forming the said partition is very simple and inexpensive.
In carrying out this invention I form the said partition in the shield by bending
up into a loop that arm of the safety pin to which the shield has to be fixed this
loop being long enough to enter the arched part of the shield in which the pointed
arm of the safety pin lies when the safety pin is closed but this said loop is so
short as to allow of the pointed arm lying in the top of the arch of the shield so
as to be sprung out from either side of the pin. In order that the arched part of
the shield where the pointed end of the pin lies may not be unduly wide I compress
and flatten the said loop thus forming the necessary thin partition in the shield.
The end part of this arm beyond the said loop or partition is bent to the form of
the end of the cap or shield and the latter which is made of trough section is closed
thereon by suitable tools worked in a press or by other means.

COMPLETE SPECIFICATION.
An Improved Safety Pin.
I, SAMUEL JOSEpi Nicklin, trading as J. Nicklin & Co., of Great Charles
Street, in the City of Birmingham, Manufacturer, 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 consists of the improved safety pin herein described which is one
of that kind in which a shield is fixed to one arm and the pointed arm is arranged
to enter the shield from either side of the pin and when the pin is closed the
pointed arm can be sprung out of the arch or trough of the shield from either side.
Within the shield of the safety pin there is a central rib or partition which
prevents the pointed arm of the pin passing straight through the shield without
entering the arch or trough and thus ensuring the said pointed arm entering the
arch of the shield where it lies when the safety pin is closed. At the present time
there are various methods of forming the said partition in the shield but the method
which I adopt of forming the said partition is very simple and inexpensive as I
will now describe by referring to the accompanying drawing on which Fig. 1

page_text: represents a safety pin constructed according to this invention; Fig. 2 shews the
same safety pin closed with the cap in section; Fig. 3 is a sectional end view of
the said safety pin on line X X of Fig. 2; Fig. 4 shews the wire part of the said
safety pin separate from the cap which latter is shewn separately by Fig. 5; Fig. 6
shews the blank from which the cap is raised.
In carrying out this invention I form the said partition a' in the shield by
bending up into a loop a¹ that arm A of the safety pin to which the shield B has
to be fixed this loop a¹ being long enough, as shewn in Figs. 1, 2 and 3, to enter
the arched part 6 of the shield B in which the pointed arm a³ of the safety pin
lies when the safety pin is closed as shewn in Fig. 2, but this said loop a¹ is so
short as to allow of the pointed arm a lying in the top of the arch 6' of the shield
so as to be sprung out from either side of the pin. In order that the arched
part b¹ of the shield B where the pointed end of the pin lies may not be unduly
wide I compress and flatten the loop a' thus forming the necessary thin partition
in the shield B. The end part a of the arm A beyond the loop or partition a¹ is
bent to the form of the end of the cap or shield B and the latter, which is made
of trough section as shewn in Fig. 5 from a sheet metal blank of the form shewn
by Fig. 6, is closed on to the arm A as shewn in Figs. 1 and 2 by suitable tools
worked in a press or by other means. The method of raising the cap B from the
blank shewn by Fig. 6 and of closing the cap on to the arm A is similar to that
employed in other well known safety pins and therefore requires no description
here. It will be observed that in closing the cap or shield B on to the arm ▲ the
portions 6³ 6* of the cap or shield are closed together in the angle a between the
main portion of the arm A and the loop a' so as to the more effectually secure
the cap or shield B on to the arm A.
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 of the kind herein referred to the combination of the arm A
made with a loop a¹ and the cap or shield B closed upon the arm so that the said
loop a' will form the central partition of the cap or shield in the manner and for
the purpose substantially as set forth.
