page_text: Fig. 5 is a similar section on line x x Fig. 1, (the pin being open).
This improved safety pin consists of a supporting plate A in which are stamped
out or otherwise formed a slot 8, a bridge t and two vertical wings or bearings l.
Between these bearings the pin proper n is mounted by means of trunnions z supported
by the said bearings.
These trunnions z form part of the head lever or cam k of the pin n.
Under the
bridget is inserted one end of a flat spring the opposite end of which is held in
the slots by the lever or cam k. In Fig. 5 the spring is in its natural position the
pin being unfastened and erected in position for use.
When from this position the pin is turned down in the direction of the arrow the
lever or cam k also presses down the springf; and when the pin on describing an
are of a circle of 90° comes to take up its closed position its end enters the bridge a
and is retained therein by the spring f. Owing to the bridge a the point of the
pinn never projects outwardly but is at all times entirely enclosed within the bridge
so that injury to the user's hand is effectively prevented. This safety pin is intended
to be stitched to the article it is desired to provide with a convenient means of
fastening. For this purpose openings o are provided in the supporting plate. This
is preferably done before the needle is mounted between the bearings.
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 fastening or safety pin consisting of a supporting plate such as A
provided with wings or bearings 1, a slots and a bridge t the pin proper being
supported by and between the said wings or bearings by means of its head k and
trunnions z, a spring f serving the purpose of retaining the pin in its open or closed
position as the case may be, and a bridge a being provided for the reception of the
point of the needle substantially as described and illustrated in the accompanying
drawings.
