PROVISIONAL SPECIFICATION.
Improved Safety Pin.
I, ADOLF GRANOWSKI, c/o German Post Office Constantinople in Turkey,
Engineer, do hereby declare the nature of this invention to be as follows:-
+
-
--
This invention consists in a safety pin made with two heads one fixed and
one movable. The point of the pin is serrated or corrugated and the movable
head through which it passes is of india rubber or flexible material lined with
a corrugated metal tube or sleeve to correspond with the point of the pin and
hold it tightly when in place therein. The elasticity of the material of which
the removable head is composed permits of its easy withdrawal, but yet keeps it
tightly held on the pin when it is placed thereon. As a substitute for the
india rubber or similar head, a metal head may be used, made hollow and with
a spring of wire or the like inside to press upon the corrugated metal tube or
sleeve which grips the end of the pin. The fixed and movable heads may be
provided with projections having small holes or rings to enable a ribbon or cord
to be passed through to connect the two heads when the pin has been passed
through the stuff to be fastened. In this last arrangement, the serrations on the-
point and in the movable head may be dispensed with.

one movable. The point of the pin is serrated or corrugated and the movable
head through which it passes is of india rubber or flexible material lined with
a corrugated metal tube or sleeve to correspond with the point of the pin and

the removable head is composed permits of its easy withdrawal, but yet keeps
it tightly. held on the pin when it is placed thereon. As a substitute for the
india rubber or similar head, a metal head may be used, made hollow and with
a spring of wire or the like inside to press upon the corrugated metal tube or
sleeve which grips the end of the pin. The fixed and movable heads may be
provided with projections having small holes or rings to enable a ribbon or cord
to be passed through to connect the two heads when the pin has been passed
through the stuff to be fastened. In this last arrangement the serrations on the
point and in the movable head may be dispensed with.
Fig. 1 is a plan view and Fig. 2 is a side elevation of a safety pin constructed
according to my invention. The pin a turns on the fixed head 6 and the point
thereof passes into the movable head c when closed. To unfasten or open the
pin the movable head c which is controlled by the spring f. between plates e. e.
on spindle d is pulled outwards. When the pin is to be closed or fastened the
movable head is again pulled by means of the knob g and the point of the pin
being inserted in the movable head c the latter is held in place by the spring f
aforesaid.
