An Improved Guard or Holder for Scarf-pins and Scarf-pins when
used as Shirt-studs.
I, AUGUST JOHN HAHN, of 61, Ship Street, Brighton, in the County of Sussex,
Jeweller and Diamond Setter, 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 device to be used in combination with a scarf-pin as
a means for preventing the said pin from being removed from the scarf or tie into
which it may be placed, except with the knowledge and consent of the wearer, and as
a means for permitting the said pin to be used as a shirt front stud, and guarding
the same against surrepticious removal while being so worn.
The said device has been designed with a view to supersede, or as an improve-
ment upon the screw system now in use with convertable scarf-pins, in which the
pin or stud head is provided with a threaded projection at the back adapted to
be screwed into a threaded socket formed in the head of the pin, when the said
stud head is to be used as a scarf pin, or into a socketed back plate when the said
stud head is to be used as a stud, but this arrangement has fallen into disfavor
and disuse, partly by reason of the said stud-head spontaneously leaving the said
pin head or back plate through the wearing out of the thread upon the said pro-
jection, and partly by reason of the mislaying or loss of the said back plate or pin,
but as, according to my invention, no such threaded portion is used, and by reason
of the fact that the said stud head is a fixture upon the pin, and that the said pin
and head are always connected to the said device, and in the same manner, whether
employed as a scarf-pin or shirt front stud, such objections are avoided by the

page_text: employment of my invention, and as the said device is always hidden from view
when in use, the same may be of cheap or non-precious metal, although employed
as hereinafter explained as a protector or guard for the most costly or valuable
pin, and as the said device according to my invention is effective and reliable it
is my intention that the same shall be commercially known as the "Defiance pin
and stud guard."
In order that my said invention and the manner of its use for the purposes stated
may be fully understood reference is hereinafter made to the accompanying
drawings, of which
Figs. 1 and 2 are front and back view respectively of my said invention, while
Fig. 3 is a vertical central section of same taken upon the line A B of Fig. 2.
Fig. 4 is a section similar to Fig. 3 but drawn to an enlarged scale, and illustrates
the bite given to the scarf pin when being placed therein, while Fig. 5 illustrates
the manner of using the said device when the pin is employed with a scarf or tie
or a shirt front.
The device constituting my invention I stamp, cut or otherwise produce from
sheet metal, precious or otherwise, of such formation that its upper end A is
preferably of the shape and configuration shewn, whilst is lower end or stem may,
by the use of suitable tools, be converted into a tube B, preferably with the junc-
tion edges C not brazed or soldered together, in order that the said tubular portion
may be slightly elastic in a lateral direction, so as to open or expand, if necessary,
for receiving the pin. D.
In a suitable position upon the flat part A, preferably just above the upper end
of the tubular portion B, I punch, press, or otherwise form upon the back face of
this a hollow or cavity E, by means of which I form a like shaped rotundity or
belly F upon the front face of the same, which, in combination with the split
or opening C in B, operates as a spring and bites the stem of the pin D while
this is being pushed into the tubular portion B as at Fig. 4, the head of the pin
ultimately resting upon the upper end of B as indicated by dotted outline in Figs. 1
and 4, and the pressure necessary to force the said pin past F in a downward
direction would also be needed to raise the pin out of B, and this could not
possibly occur without the knowledge of the wearer.
In Fig. 5 the part G represents either a scarf or the front of a shirt so far as
regards the application of my invention, and if the former, the pin would be
passed through from the front to the back of the tie G, and the said device A B
be pushed up onto the pin D until secured thereon, but if G be a shirt front the
'pin would be passed through the stud hole therein, and the device be placed
upon D in the same manner, and by reason of the flat portion A lying flat against
"the under vest of the wearer, the tubular portion B would be kept perpendicular
and the head of the pin D always in a proper position.
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:
As a guard or protector for scarf pins, and as a means by which such pins may
be used as shirt studs, the construction, use, and application of the herein described
device, substantially as and for the purposes specified, and in the manner herein
set forth and shewn by the accompanying drawings.
