GEORGE WILLIAM DAWSON, of Birmingham, in the County of Warwick,
Jeweller. "IMPROVEMENTS IN THE FASTENINGS FOR BRACELETS, AND OTHER
SIMILAR ARTICLES."
My improvements consist of sliding plates working at the back of the mouth-
piece; at the inside end of this sliding or gripping plate is a hoop or catch which
passes through the mouthpiece and works in a slot in it and takes into a slot in
the opposite mouthpiece; these slides or gripping plates are actuated or forced
into their normal position by a spiral spring fixed between them to release the
catch; to open the bracelet, pushers or knobs are provided on the side of the
bracelet which when pushed compress the spiral spring and allow the grips to
pass freely through the slot in the mouthpiece.
My Invention may be used also by the gripping being formed by studs or hooks
being fastened to or projecting from the opposite side mouthpiece to that in
which the slide or gripping plates are in. In this case the studs or hooks are
nicked or catched on the inside, the outside edge being left solid for steadying the
bracelet; when closed the action of the sliding or gripping plates in this are the
same as before described, being actuated by a spiral spring, only that instead of the
gripping hooks being attached to the sliding plates there are holes in to receive
the studs that are in the opposite mouthpiece. I also make my Invention to work
with one sliding plate at the back of the mouthpiece; this sliding plate carries two
studs or hooks, one as near as possible to each end; the grips or hooks on this plate
have the grips both one way, which take into slots in the opposite mouthpiece.
This one is actuated by a spiral spring taking against the end of the sliding plate
and the side of the bracelet; on the opposite end of the sliding plate is a pusher
taking through the side of the bracelet. I also make my Invention to work with one
sliding or gripping plate having holes in in the place of the studs or hooks, as before
described, the said studs or hooks being fastened to or projecting from the opposite
mouthpiece to that in which the sliding or gripping plate is fitted in. This plate
is also actuated and brought into its normal position by a spiral spring actuating
between the end of the gripping plate and the bracket side at the opposite end to
the pusher.
All the above described motions work vertically and are actuated by spiral
springs.

page_text: My Invention can also be worked by plates of metal being fastened to the sides
of the bracelet; these plates are made to fit to the inside of the mouthpiece;
and on
the end is formed a stud or book, which said stud or hook takes into the opposite
mouthpiece; this plate is made to form its own spring by having slots cut in to
free the centre part which carries the studs or hooks. I do not confine myself to 5
placing the hooks or grips on the end of the bellcrank piece, but can fix the hook or
studs on the opposite mouthpiece and to take into holes in the end of the
bellcranked self springing piece. I do not confine myself to the spiral spring as a
means of actuating, but use any other convenient spring.
