I OLIVER GRIFFITHS GOODMAN of 82 Caroline Street Birmingham in the County of
Warwick Pin and Needle Manufacturer do hereby declare the nature of this invention
to be as follows:-
The Double Pronged Safety Pin consists of two parts, the back and the double
pronged pin, united by a hinge as hereinafter described.
The back consists of a strip of any suitable metal of a convenient length and breadth.
One end of this strip is stamped out and curled under so as to form the barrel of a
hinge, or the barrel of a hinge may be made separately and attached to it underneath.
The other end of the back is beaten or stamped out so as to form two flanges one
projecting from each side of the strip or back. These flanges are then folded under
and are of such a shape and so folded that they almost meet underneath the strip or
back but leave sufficient space between their edges for the insertion of the prongs of
the pin. This end of the back with its flanges thus turned under forms the cap or
sheath.
The centre part of the back (from the hinge to the commencement of the cap or
sheath) is raised or bowed. It may be of any convenient or ornamental shape which
will insure sufficient rigidity and strength.
The pin
made of wire of suitable thickness and character. One end of it is passed
through the barrel or clasp of the hinge (in which the pin should nicely fit and yet be
at liberty to revolve on its longitudinal axis), until an equal length projects on each
side of the barrel of the hinge. The two ends are then bent so as to assume a position
parallel with each other and vertical to the barrel of the hinge. The pin is of such a
length that when thus bent and turned on the hinge towards the cap or sheath, the
ends will reach well into the sheath but will not project beyond it. The ends are
pointed and the pin is made of hard metal so that if the ends be pressed together they
will on the pressure being released spring open again and resume their position
parallel to each other.
In using, the prongs are first withdrawn from the cap or sheath and the hinge
opened to any convenient angle; both prongs are thrust through the articles to be

page_text: secured, maintaining at the same time their parallel positions; the projecting points
are then both inserted between the flanges of the cap or sheath when their spring and
the pressure of the material forces them apart between the flanges and the back of the
sheath. A very secure fastening is thus made whilst at the same time the points of
the prongs are perfectly guarded.
The double pronged safety pin is applicable for all the purposes to which safety
pins, shawl pins bandage pins and brooch pins are applied. In the case of a brooch
the brooch itself may be made to constitute the back of the safety pin.

page_text: I OLIVER GRIFFITHS GOODMAN of 82 Caroline Street Birmingham in the County of
Warwick Pin and Needle 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:
The double pronged safety pin consists of two parts the back and the double pronged
pin united by a hinge as hereinafter described.
The back consists of a strip of any suitable metal of a convenient length and
breadth. One end of this strip is stamped out and curled under so as to form the
barrel of a hinge or the barrel of a hinge may be made separately and attached to it
underneath. The other end of the back is beaten or stamped out so as to form two
flanges, one projecting from each side of the strip or back. These flanges are then
folded under and are of such a shape and so folded that they almost meet underneath
the strip or back but leave sufficient space between their edges and between the under-
side of the back and the inner side of the flange for the insertion of the prongs of the
pin. This end of the back with its flanges thus turned under forms the cap or
sheath.
The centre part of the back (from the hinge to the commencement of the cap or
sheath) is raised or bowed. It may be of any convenient or ornamental shape which
will insure sufficient rigidity and strength.
The pin is made of wire of suitable thickness and character. One end of it is
passed through the barrel or clasp of the hinge (in which the pin should nicely fit and
yet be at liberty to revolve on its longitudinal axis) until an equal length projects on
each side of the barrel of the hinge. The two ends are then bent so as to assume a
position parallel with each other and vertical to the barrel of the hinge. The pin is of
such a length that when thus bent and turned on the hinge towards the cap or sheath,
the ends will reach well into the sheath but will not project beyond it. The ends are
pointed and the pin is made of hard metal so that if the ends be pressed together they
will on the pressure being released spring open again and resume their position parallel

are then both inserted between the flanges of the cap or sheath, when their spring and
the pressure of the material forces them apart between the flanges and the back of the
sheath. A very secure fastening is thus made whilst at the same time the points of
the prongs are perfectly guarded.
The double pronged safety pin is applicable for all the purposes to which safety pins,
shawl pins, bandage pins, and brooch pins are applied. In the case of a brooch the
brooch itself may be made to constitute the back of the safety pin.
In the accompanying drawings figure 1 represents a vertical view of the double
pronged safety pin lying on its back. A A is the back, B the barrel of the hinge and

page_text: PPPP the double pronged pin. The dotted lines indicate the position of the pins
when being inserted or withdrawn from the sheath S S.
Figure 2 represents a lateral view of the double pronged pin in the same position.
The letters A A, B, P P and S represent the same parts in this figure as they do in
figure 1. The dotted lines from B to P¹ indicate the position of the pin when
withdrawn from the sheath and in process of being opened to its full extent.
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 making of a safety pin with a double prong.
2. The combination of parts and method of manufacture above described.
