PROVISIONAL SPECIFICATION.
Improvements in Rings and such like Articles of Jewellery.
I, WILLIAM HENRY DOUGLAS of 59 High Street, Stourbridge in the County
of Worcester, Watchmaker, do hereby declare the nature of this invention to be as
follows:-
This invention has for its object the formation of a self closing and expanding
ring suitable for finger, scarf, and such like purposes.
It consists of a flat metal band one end of which is fastened to the head or
ornamental part of the ring and the other end fitted to slide loosely in a groove or
socket under the head. Or both ends of the band may be fitted under the head to
slide in this manner.
The band may be covered either with a continuous spiral of wire or a series of
disconnected links or beads, so as not to interfere with the flexibility of the inner
band. If desired the ring may consist of the spiral wire only without the
inner band.
Dated this 1st day of June 1894.

Improvements in Rings and such like Articles of Jewellery.
I, WILLIAM HENRY DOUGLAS of 59 High Street, Stourbridge in the County
of Worcester, Watchmaker, 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 :-
This invention has for its object the formation of a self closing and expanding
ring suitable for finger, scarf and such like purposes.
It consists of a flat metal band one end of which is fastened to the head or
ornamental part of the ring and the other end fitted to slide loosely in a groove
or socket under the head. Or both ends of the band may be fitted to slide under
the head in this manner. The band is covered either with a continuous spiral of
wire or with a series of disconnected links or beads, so as not to interfere with the
flexibility of the inner band.
If desired the ring may consist of the spiral or flexible cable without the inner
band or core.
Reference should be had to the accompanying drawings and to the letters and
figures marked thereon to assist in the fuller description of this my invention. The
figures being drawn to an enlarged scale the better to shew the various parts.
Fig. 1 illustrates a complete finger ring.
Figs. 2 & 3 illustrate one form of my invention in two positions, being sectional
views shewing the parts behind the head or ornament.
Figs. 4 & 5 are similar views to Figs. 2 & 3 of another form of invention.
Fig. 6 is a similar view through a bracelet, and
Figs. 7 & 8 details shewing securing arrangement.
my

page_text: The shank of the ring consists of an inner core of metal covered with a spiral of
metal (a) the one end (6) being attached to the head or ornament of the ring the
other end telescoping into the head at (c) and having upon it a stud or button
at (d) sliding in the groove (e) so that when required. to be of a small size it will
be closed up as in Fig. 3, when required to expand, more or less, as at Fig. 2.
In Figs. 4 & 5 (a) is the flexible shank upon one end of which is fixed the head
beneath which are the bars (f) (f) upon which slides the clip (g) at the other end
of the flexible shank (a), so, that when the ring, is closed up to its smallest
dimension as at Fig. 5 it can be expanded to any required size by reason of the
clip (9) sliding upon the bars (f) (f), the natural tendency of the shank (a) to
close up causing the ring to grip at any point to which it is expanded. This, may
be further ensured by, placing the spiral springs, (h) (h) upon the bars (ƒ) (ƒ).
In either of these cases illustrated in Figs. 2, 3, 4, & 5 instead of the spiral with
'a core I may use a cable or flexible shank without a core.
A further advantage to that of being able to vary the size of the shank is that
the shank can be easily disconnected from the head without interfering with the
setting...
When desiring to fix the ring in any of its expanded positions. I adopt the
following arrangement which is especially suitable when applied to bracelets made
according to this my invention.
Referring to Fig. 6 which shews a bracelet partially closed,
A loose plate with a raised centre (i) Figs. 7 & 8 is inserted between the
spiral (a) of the bracelet and a wedge piece (k) through which a pin (p) is inserted
securing the loose plate (i) and wedge piece (k) and acting as a pivot for the
latter (). Across on the underside of the bracelet is a bar. or sharp, edge (1) so
that when the wedge, piece (k) is turned over the raised centre (i) of the. loose
plate it will wedge between the loose plate and the flexible band (a) of the bracelet
and cause the bar or sharp edge (7) to bite into the spirals and hold the band firmly
in any position to which it has been expanded.
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. Rings, bracelets, and such like articles, of jewellery, capable of expanding
and adjusting themselves to various, sizes substantially as herein set forth and
specified...
2. In rings, bracelets and such like articles of jewellery made to expand fixing
them in their expanded position by use of a wedge, substantially as herein
set forth.
