COMPLETE SPECIFICATION.
A New or Improved Safety Pin.
I STEPHEN WALLEY PEALEY of The Haven Christchurch Park Sutton in the
County of Surrey, Gentleman 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:-
My invention relates to a new or improved safety pin having for its object to
provide surgeons, hospital and other nurses, and others with a fastening for
bandages, articles of clothing &c. free from danger of scratching or pricking the
wearer or other person or tearing or otherwise injuring any clothing which may
come in contact therewith. In carrying my invention into practical effect I
provide a pin of suitable material and of the size required similar to an ordinary
brass draper's pin with the exception of the point which is rounded off and made
blunt instead of being sharp. The said pin is furnished with a sheath or case of
thin metal terminating in a point as sharp as that of a pin in general use, so as to
assist the abovementioned pointless pin, contained in the said sheath or case, in its
When the
passage through the material composing the bandage or garment.
pointed sheath is fixed in the material to be pinned, the said sheath may be
withdrawn, thus leaving only the pointless pin therein, whereby all danger of
scratching or pricking is obviated. Instead of the sheath being pointed, the point
of an ordinary pin may be caused to project beyond the front end of the sheath
to assist the latter being passed through the material, after which the pin may be
withdrawn from the sheath and passed, point foremost, through the front end of the
sheath, the latter thus holding the pin and covering its point or the pin may be so
constructed that the sheath may pass over a reduced prolongation of the same, the
pointed part of the pin being withdrawn from the sheath when the latter is fixed in
position in the material.
And in order that my said invention may be more fully understood, I will
describe the same with reference to the accompanying sheet of drawings, in which
Fig. 1 shows my improved pin,-drawn to an enlarged scale for the sake of
clearness, with the pointed sheath thereof in section,
Fig. 2 showing the pointless pin fixed in the material to be pinned, the pointing
sheath having been withdrawn.
a represents the pointless pin, and 6 the pointed sheath in position thereon. The
point of the pin is rounded off, or made blunt, as shown at a and when the sheath
is passed through the material c to be pinned, it may be withdrawn thus leaving
the pin a in the material as shown in Fig. 2. The point a' may likewise be covered
with a thin coating of india-rubber. In the modification shown in Figs. 3 and 4,
an ordinary pin is used, the point projecting a short distance beyond the front of
the sheath b in order to assist in passing the latter through the material c; the pin
is then withdrawn from the sheath and passed point foremost through the front end
of the sheath, wherein it is fixed, the point being protected as shewn in Fig. 4.
The front end of the sheath is preferably bevelled off or reduced, as shewn at 6'
to assist it in passing through the material c. According to the modification
shown in Figs. 5 and 6, my improved pin is constructed with a sharp pointed end d
provided with a reduced prolongation d' over which is passed the sheath b. When
the pointed end d and the sheath have been passed through the material c the
said end is withdrawn from the sheath, leaving the latter alone in the material as
shown in Fig. 6.

page_text: Having now fully described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1.) The improved safety pin constructed with a blunted point a¹ and a pointed
sheath b substantially as described and shown.
2.) The improved safety pin substantially as described and shown with
reference respectively to Figs. 3 and 4, and to Figs. 5 and 6 of the accompanying
drawings.
3.) The improved safety pin substantially as described and shown in the accom-
panying drawings and for the purposes set forth.
Dated this 22nd day of February 1893.
