Year: 1876

page_text: LETTERS PATENT to James Grason, of 4, Fore Street, Tiverton, in the County
of Devon, Jeweller, for the Invention of "AN IMPROVED SELF-LOCKING SHIRT
STUD, APPLICABLE ALSO FOR OTHER FASTENING PURPOSES."
Sealed the 13th April 1877, and dated the 17th October 1876.
PROVISIONAL SPECIFICATION left by the said James Grason at the Office
of the Commissioners of Patents on the 17th October 1876.
JAMES GRASON, of 4, Fore Street, Tiverton, in the County of Devon, Jeweller.
"AN IMPROVED SELF-LOCKING SHIRT STUD, APPLICABLE ALSO FOR OTHER FASTENING
PURPOSES."
According to this Invention I make the front disc and the stem of the stud in
one piece, and I make the back disc in two half parts like flaps and join them to
the stem. Each half flap is provided with a half sleeve which fits round the stern
when the stud is locked. These sleeves are preferably made tapering towards the
front in order that the front disc of the stud may be close to the fabric, the button
hole by preference fitting round the smaller front, part of the two half sleeves thus
preventing the flaps from opening when the stud is inserted. The inner end of the
stem is preferably formed with a stop to keep the two flaps steady while the stud is
being inserted.
To insert the stud, close up the two flaps of the inner disc and pass them thus
folded through the button hole, the flaps will then open and the two half sleeves be
passed through, locking the stud in the button hole.
Studs made according to this Invention are also applicable to sleeve links and to
many other fastening purposes.
20 SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said James Grason in the Great Seal Patent Office on the 17th April
1877.

According to this Invention I make the front disc or button and the stem of the
stud in one piece, and I make the back disc in two half parts like flaps and joint
them to the stem. Each half flap is provided with a half sleeve which fits round
the stem when the stud is locked or fixed in its place in the shirt front or other
article. These sleeves are preferably made tapering towards the front in order
that the front disc or button may be close to the fabric, the button hole then
naturally fitting round the smaller front part of the two half sleeves in their closed
or folded up position round the stem when the stud is inserted, the half flaps are
thus prevented from opening or unlocking. The inner end of the stem is preferably
formed with a stop to keep the two flaps steady while the stud is being inserted.
The Drawing hereunto annexed represents a shirt stud drawn to an enlarged
scale.
Figure 1 shows a side view of the stud open, ready to be inserted.
Figure 2, a side view of the stud as it would appear when inserted.
Figure 3 shows another view of the stud when inserted, and Figure 4 a plan view
of the back of the said stud.
At each of the above Figures similar letters are employed to denote corresponding
parts.
a represents the front disc and stem or shank of the stud formed in one piece,
the back disc is formed in two halves c, c, like flaps and jointed to the stem a at d;
e, e, are half sleeves fixed to the flaps c, c, so as to fit round the stem a when the
stud is fixed in place, as represented in Figures 2 and 3. The said sleeves are made
tapering towards the front in order that the front disc may be close to the fabric,
the button hole fitting round the smaller front part of the two half sleeves, thus
preventing the flaps from unlocking when the stud is inserted; f is a stop to keep
the two flaps c, c, steady while the stud is being inserted. To insert a stud con-
structed as above, close the two flaps c, c, together in position represented at Figure
1, and pass them thus folded through the button hole, the flaps will then open as in
Figures 2 and 3, and the stud will be locked in the button hole. To withdraw the
stud it is simply necessary to push it from the back; so that the two flaps may fold
together.
Studs made according to this Invention are applicable to sleeve links and many
other fastening purposes.
And having thus fully described and ascertained the nature of this my Invention,
I declare that I claim, forming one end disc or button or cross bar of a shirt stud or
similar article in two jointed halves, and fitting the said halves with half sleeves
for facilitating the insertion of such stud into its button hole and retaining it therein,
as herein-before described and shown.
In witness whereof, I, the said James Grason, have hereunto set my hand
and seal, this Fourteenth day of April, in the year of our Lord One
thousand eight hundred and seventy-seven.
