JAMES CLARK 3 & 4 Bartlett Street Bath and County of Somerset Working
Jeweller Watch Maker & Optician I, James Clark do hereby declare the nature of
my invention for AN IMPROVED FASTENING FOR STUDS, SOLITAIRES AND OTHER
THINGS WHERE APPLICABLE THE MOVEABLE PARTS BEING UNDETACHABLE to be as
follows -
The back or under part of Stud, Solitaire &c. is an ordinary disc with a hole in the
centrè, fixed to it is a hollow, round oblong, or oval shank in which a spiral or bent
spring is placed. To the upper end of the shank is fixed an oblong or oval plate
(fashioned to a pattern or plain) having a gap sunk in its centre, with a pin hole in
the centre of the gap-A moveable front is made of an oblong or oval plate similar
in size to that on the upper part of the shank, having a square-headed pin fixed
vertically underneath by the head to its centre. The square head being of a size to
fit comfortably into the aforesaid gap of oblong or oval plate, the round pin attached
to thes quare head passes down through the spring in the shank, a washer is put
on it below the spring and a rivet head is formed at the end of the pin, sufficient play
being allowed for the square head to be drawn up out of the gap, to turn.
The arrangement of the upper parts may be varied (without affecting the principle)
by making the front with an edge to fit down over the plate beneath it, and the gap
cut in its centre, instead of in plate beneath, or partially in both, In these forms a
square head to the pin, might not be necessary. When the front plate and the plate
with the gap are parallel, the Stud or Solitaire easily passes through any ordinary
button hole or slit, To secure it in its place draw up the front plate sufficiently to
take the square head of pin ont of the gap, give it one quarter turn & press it down
again, The front plate will then be across the plate with the gap and so form a cross,
The spring being so arranged as to draw the front downwards towards the back & so
keeps it, (the front) in place. The contrary action, or one more quarter turn the same
way, drawing up the front as before, will again bring the upper plates parallel and
allow the Stud or Solitaire to be easily removed from the article it has been attached to.

Applicable, the Moveable Parts being Undetachable.
I, JAMES CLARK of 3 Bartlett Street Bath and County of Somerset Working
Joweller and Watch Maker do hereby declare the nature of my invention for AN
IMPROVED FASTENING FOR STUDS, SOLITAIRES AND OTHER THINGS WHERE APPLICABLE
THE MOVEABLE PARTS BEING UNDETACHABLE and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
The back or under part of Stud Solitaire &c. is an ordinary disc or plate with a
hole in the centre-fixed to it is a hollow shank in which a spiral or other shaped spring
is placed.
To the upper end of the Shank an oblong or oval plate is fixed, having a gap and
pin hole sunk in the centre Or two gaps sunk crosswise with a pin hole in the
centre.
A Moveable front is made of an oblong or oval form somewhat similar in size to
that on the upper end of the shank, Having one or more transverse projections under-
noath, of a size to fit comfortably into the aforesaid gap or gaps, with a pin extending
from the centre downwards-The moveable front is attached to the lower part by the
pin passing through the shank and through the spring in the shank, and a washer
being put on the pin below the spring and a rivet head formed at the end of the pin
sufficient play being allowed for the projection or projections under the front to be
drawn up out of the gap or gaps, to be turned-The inake of the parts can be varied
by having a rim to the moveable front to fit down over the upper plate on the shank
when both are placed parallel and a gap or gaps cut in the rim or in the plate on the
upper end of the shank or partially in both, to hold the front in place when it is placed
crosswise, in this form the projection under the front can be dispensed with.
When the front and under plate are parallel, the Stud or Solitaire easily passes
through any ordinary button hole or slit, To secure it therein, draw up the front
until it is clear of the gap or gaps give it one quarter turn either way-The front
will then be across the under plate,-the spring in the shank being so arranged as to
draw the front downwards towards the back and so keep it in place. The contrary
action or one more quarter turn the same way-drawing up the front as before-will
again bring the upper parts parallel.
Annexed are drawings in illustration of my invention in the two forms as before
described. .

page_text: 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 "An
Improved fastening for Studs Solitaires and other things where applicable the move-
able parts being undetachable."
1st by means of a moveable front with projection or projections underneath, and a
pin extending therefrom, and the arrangement of the spring, washer and rivet upon it.
2ndly (or) by means of a moveable front with a rim round or outside it, with or
without a gap or gaps, and a pin extending from the centre and the arrangement of
the spring, washer and rivet upon it.
3rdly by the combination of either of the above fronts with a hollow shank having
a gap or gaps and a disc at the back of the shank as hereinbefore described and
illustrated.
