I, MALCOLM FRISEN, of 26 Temple Street, Paterson, County of Passaic and
State of New Jersey, U.S.A., Ribbon Weaver, do hereby declare the nature of
my 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 relates to a new and useful improvement in fastening devices and
it is particularly applicable to fastening pins used in securing tags to fabrics. It
consists in the improved construction whereby the point of the fastening device may
be securely locked and easily disengaged from the body of the pin, and it also
consists in the novel construction and arrangement of parts hereinafter more fully
set forth and claimed.
In the drawings
Figure 1 is a side elevation of the improved fastener with price tag attached,
showing the fastener locked,
Figure 2 is a top plan view of the fastener,
Figure 3 is an enlarged detailed view showing the construction of the point and
body of the pin whereby the same may be locked into engagement with each other,
and
Figure 4 is a vertical section on the line x-x of Figure 1.
In the drawings a is the body of the pin made preferably of thin wire. The end b
of the wire is coiled substantially as shown to form a double curved portion c
between the arms of which the point d of the pin is adapted to enter and
be held.
The point d of the pin has near its extreme end two flattened surfaces e and farranged
in planes approximately at right angles to each other. Between these flattened
Burfaces e and f is formed a ridge g. The arms of the extreme point of the double
curved portion c are bent inwards to form a neck or contracted aperture substan-
tially as shown in Fig. 4. This aperture is sufficiently wide to admit of the
entrance of the point of the pin, but serves to bind upon and firmly hold the ridge g
when the pin is under a longitudinal strain.
It is manifest that this locking device is applicable to safety pins and similar
fastening pins and that the essential feature of the present invention is a fastening
pin having an enlargement g near its pointed end and at its other end a recess or
slot into which the point and enlargement are adapted to enter, but which serves
by its contracted aperture 7 binding upon the enlargement g to retain the point
within the slot when lateral or longitudinal strain is brought to bear upon the
locked pin.
Having now particularly 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-A fastening pin or similar device, having the pointed end provided with an
enlargement near the point and a slotted end having a contracted aperture into which
the point is adapted to enter and be locked against lateral strain, substantially as
described.
2-A fastening pin or similar device having at or near the pointed end, two
flattened portions arranged approximately at right angles to each other, and adapted

page_text: tolenter and to engage the slotted opposite end of said pin, substantially as and for
the purposes set forth.
