Year: 1884

County of Warwick do hereby declare the nature of my invention for AN
IMPROVED HAIR PIN to be as follows:-
The wire of the pin is bent in such a manner that a twist is needed to insert it
in the hair. When in the hair it springs so as to form a clip and cannot be
withdrawn without the reverse twist, thus:-I form my wire to the shape of an
ordinary hair pin. I then bend it with suitable tools until the wires cross each
other at about the centre of the pin, the ends of the wire to the extent of half an
inch each, are then turned parallel with each other as before. The hair pin thus
presents the appearance of a cross in or near its centre and
penetrate the hair & the reverse twist to withdraw it.

Birmingham do hereby declare the nature of my invention for "AN IMPROVED
HAIR PIN" and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
My invention consists of an improved hair pin constructed in the manner herein
after described and illustrated in the accompanying Drawing.
My said improved hair pin possesses the advantage over ordinary hair pins in
the respect that when inserted in the hair that its position is so fixed that it is not
liable to become accidentally detached from the hair thereby allowing the lock or
portion of hair which had been supported by it to fall and the dressing of the hair
deranged.
In making an improved hair pin according to my invention I bend the wire of
which it is made at its middle so as to form a hair pin of the ordinary kind.
I then bend each of the limbs or branches of the pin near its middle at an obtuse
angle so as to make the lower halves of the pin cross each other. The crossing
parts are again bent at a similar angle to the first described bending but in the
opposite direction the extreme open ends of the hair pin are thus brought into a
position nearly parallel to one another. The hair pin thus produced has the
appearance of an ordinary hair pin with its branches crossing at or near its
middle.
The crossing parts may be made in the wire before the latter is doubled at its
middle to form the hair pin.
Figure 1 of the accompanying Drawing represents in elevation a hair pin made
according to my invention
a abba are the two branches of the hair pin. Near
the middle of the branches they are bent as represented in the Drawing that is
each branch is bent twice at an obtuse angle the bendings being in opposite
directions whereby the said branches are made to cross each other the end a³ of the
branch a a² being in a line with the part b of the branch bb' and the end 62 of the
branch bb being in a line with the part a of the branch a a².
Instead of making the bendings of the branches of the hair pin where they cross
angular they may be made of a curved form as represented in Figure 2 in which
Figure 2 it will be seen that the crossing parts are curved instead of angular.
I prefer however to bend the branches in the manner illustrated in Figure 1.
That portion of the hair pin between the crossing parts and top or bent part
constitutes a temporarily closed loop d which when the hair pin is in use grips the
lock of hair as herein after explained.
In using the hair pin the open ends a² b² are passed into the hair so as to grasp
the lock of hair c Figure 3. In order to permit the crossing parts of the pin to pass
the lock of hair c the said pin twists or turns through a right angle as represented
in Figure 4. When the loop d of the pin has been advanced upon the lock of
hair c the pin twists or turns through another right angle in the same direction as
before as represented in Figure 5 by comparing which Figure 5 with Figure 3 it
will be seen that the hair pin has performed a semi-rotation the branch a² which is
uppermost in Figure 3 being undermost in Figure 5 and the branch 62 which was
lowest in Figure 3 being uppermost in Figure 5.
In withdrawing the hair pin it moves or twists in a direction the reverse of
that by which it was introduced into the hair.
In addition to the twisting motion of the pin in causing its crossing parts to pass
the lock of hair c some pressure has to be exerted in order to separate the two

page_text: branches at the crossing parts to a distance equal to the thickness of the lock of
hair c the said branches when in their normal positions lying close upon one
another.
In consequence of this resistance when the lock of hair c passes the crossing
parts in either direction the pin when inserted in its place in the hair retains its
position with considerable firmness and is not liable to be accidentally withdrawn
from the hair.
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 An improved hair pin constructed in the manner herein before described
and illustrated in the accompanying Drawing that is to say a hair pin the two
branches of which cross each other at or near their middles so that the said hair
pin on being inserted in the hair requires to be pressed with considerable force and
to perform a semi-rotation in order to make the crossing parts pass the portion of
the hair embraced by the hair pin thereby causing the hair pin to retain its placo
with considerable force substantially as described and illustrated.
