An Improved Safety Pin.
I, CHARLES BAYER, of 31, London Wall, in the City of London, Manufacturer,
do hereby declare the nature of this invention to be as follows :-
This invention consists of an improved duplex or twin safety-pin composed
substantially of two safety-pins lying in the same plane and firmly united back to
back and heel to point.
The two pins are made of two similar pieces of wire pointed at one end as usual
and flattened at an intermediate part which will form the back bar of the safety-
pin. The wire is bent sharply at the heel end of the pin proper and then curled
to form the spring at the one end of the back bar at the other end of which the
wire is curved to a hook shape and doubled on itself to the form of a hook-shaped
bow to form the protecting guard within which the point of the pin is engaged and
by which it is shielded, the butt end of the wire after the hook-shaped bow is
completed being bent around the back bar of that safety-pin and likewise around
that of the other safety-pin upon the two sides of which this butt end is tightly
clamped. The flattened back bars of the two pins are thus firmly united at both
ends and they lie in the same plane edge to edge, the pin points being oppositely
directed.
The strength of this construction is such as could not be obtained by the ordinary
form of pin.

I, CHARLES BAYER of 31, London Wall in the City of London, 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 an improved duplex or twin safety pin fastener
composed substantially of two safety pins lying in the same plane and firmly
united back to back.
The general purpose of the duplex safety pin fastener is to enable articles of
underclothing or parts of the same article to be fastened together much more easily
and in a way not possible with a single safety pin, the duplex construction enabling
the fastener to remain attached to the one article or part when unfastened from the
other article or part so that where, as in the case of infants body appliances, frequent
fastening and unfastening is necessary, the fastener need never be wholly detached
and cannot therefore be mislaid.

page_text: The invention is illustrated in the accompanying drawings forming part of this
specification wherein
Figure 1 shews a face view of the duplex pin in the closed position and
Figure 2 is a cross section at one of the points of connection, both figures being
drawn to a magnified scale.
The two safety pins are of ordinary form being made of two similar pieces of
wire pointed at one end as usual except that the wires are flattened at certain
points of the intermediate part which will form the back bar of the safety pin. The
wire is curled to form the usual spring 6 at the heel end of the pin a and at the
opposite end of the back bar c the wire is curved to and doubled on itself to
the form of a hook-shaped bow d constituting the protecting guard within which
the point of the pin a is engaged and by which it is shielded as shewn, the butt
end of the wire after the hook-shaped bow is completed being bent around the
back bar c. Two pins thus formed are placed back to back, the curl spring 6 of
the one being opposite the guard or bow d of the other and they are rigidly united
in this position by two metal clips e embracing flattened portions f of the juxtaposed
back bars c so that the clips being tightly clenched upon the back bars the two
safety pins will be rigidly united at both ends of the back bars and retained in the
same plane edge to edge, the pin points being oppositely directed.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what I
claim is :-
The herein described duplex or twin safety pin constructed of two safety pins
formed as described, lying in the same plane and rigidly united back bar to back
bar substantially in the manner and for the purpose specified.
