COMPLETE SPECIFICATION.
An Improved Curling Pin.
I, THOMAS CHARLES CAMPBELL of 8 Grainger Street in the City and County
of Newcastle on Tyne, Dentist, 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 an improved curling pin and has for its object simplicity
combined with cheapness and efficiency.
To carry out my invention, I employ by preference wire twisted into the requisite
shape or form as hereinafter described so that the hair can be easily grasped, then
twisted or wound round the wire and finally retained in this position for as long a
time as may be required.
I will describe my invention with reference to the accompanying drawings in
which
Figure 1 shows a perspective view, Figure 2 a plan view and Figure 3 a side
view of a curling pin constructed after my invention and throughout this description
like marks of reference indicate like parts.
Referring to the drawings, it will be seen that each curling pin consists primarily
of a piece of wire bent into the shape of the letter U; both arms of the U are
then further indented as shown at a and finally to complete the pin, the closed end
of the U must be bent over as shown in the drawings.
The object of the flexure at a is to form a fulcrum at this point so that when the
points are nipped together between the finger and thumb, the arms ce may be
forced open.
The object of bending over the closed end of the U is to form a
clasp for the hair as hereinafter shown.
To curl hair, proceed as follows:--Clasp the hair to be curled between the
arms ee, which may be opened by nipping together the ends of the pin as above
described, the flexure a in the wire acting as a fulcrum for the notion. Then
proceed to turn over the pin so as to roll the hair around it and when the length
of hair has been rolled up as described, grasp the roll in the left hand and with the
right fore finger push the pin further into the roll of hair so as to grip the hair
between the arms of the pin and the short bent over or closed end thereof as shown
in Fig. 3.
The resilient action of the pin constructed as above described will keep the hair
in its curled-up state as long as required when it can be drawn out and the hair
will be curled.
I can conveniently construct curling pins as above described out of ordinary
hair pins by forming the necessary flexures in the wire in the manner above
described.
The flexures a are not absolutely essential to the manufacture of curling pins
made in accordance with my invention because when parallel wires without flexures
are nipped together at their closed end, the free ends will still open to a certain
extent The Hexures tend to improve the working, to stiffen the pin and to increase
the grip of the bent over clasp and therefore I prefer to use them.
The wire used may be round or flattened so that it may more easily enter 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
1. The improved construction of curling pin consisting in forming each pin out

set forth.
2. The improved construction of curling pin consisting in forming it out of
unjointed wire with facilities for clasping the hair when rolled on the pin substan-
tially as herein set forth.
