page_text: We THOMAS WILSON and JOHN WILLIAM WILSON trading under the Style.or
firm of Wilson. Brothers of Skinner Street, Whitby in the County of York,
Jet ornament Manufacturers do hereby declare the nature of this invention to be
as follows:-
Our invention relates to improvements in jet and other bracelets whether
composed of separate pieces or built up of sections united together. Heretofore
the separate pieces composing a jet or similar bracelet bave usually been strung
like beads upon elastic cords in order that the pieces should be held in close contact
with one another and to enable the bracelet to be stretched and sprung over the
hand of the wearer, but such cords have the objection of permitting undue
transverse flexibility between the several pieces which are consequently liable to
become abraded or chipped. by contact with one another, and the elastic.cords are
liable to wear and break and thus allow the pieces of the bracelet to become
unstrung or detached from one another and lost.
Our invention has for its object to avoid these objections and to render a bracelet
of this kind sufficiently stiff to prevent angular motion between the several
segments and yet sufficiently elastic as a whole to permit of its being opened out
for the purpose of passing it over the hand of the wearer.
For this purpose, the several pieces or sections are slipped upon a. ribbon of
spring steel (one or more) having an initial curvature causing the bracelet to tend
to coil up, so that should the ends of the bracelet become unfastened the bracelet
will cling to the arm of the wearer.
The end segments are made fast to the spring strip or ribbon and are provided
with a suitable snap or other fastening. The pieces or segments are further strung
upon a non-elastic cord or cords to prevent twisting of the separate pieces upon the
steel spring.
In the case of a built up" bracelet each rigid half of which is composed of, a
number of sections or pieces which are usually cemented or otherwise united, the
halves being hinged together, the steel spring is passed through the segments in the
manner above described and across the hinge joint the effect being to secure
the segments rigidly together and to prevent the halves opening out wide and
cause the bracelet to cling to the arm when the snap is unfastened.

page_text: We THOMAS WILSON and JOHN WILLIAM WILSON trading under the Style or
firm of Wilson Brothers of Skinner Street Whitby in the County of York jet
ornament Manufacturers 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 :—
'
Our Invention relates to improvements in jet and other bracelets whether
composed of separate pieces or built up of sections united together. Heretofore
the separate pieces composing a jet or similar bracelet have usually been strung
like beads upon cords which are either endless and elastic, to enable the bracelet to
be stretched and sprung over the hand of the wearer, or which are non elastic and
not endless, the ends of the bracelet being united by a snap fastening. Such cords
are very liable to break and allow the pieces to become unstrung and lost;
moreover owing to the great degree of flexibility of the bracelet, the pieces of
which it is composed are liable to become abraded or chipped by contact with one
another and in the case of non-elastic cords, the bracelet is liable to be lost should
the snap become unfastened, as the bracelet does not cling to the arm of the
i wearer.
Our invention has for its object to avoid these objections and to render a bracelet
of this kind sufficiently rigid to prevent angular motion between the several
segments, so as to avoid chipping and yet sufficiently flexible as a whole to permit
of its being opened out for the purpose of passing it over the hand and to give it a
tendency to cling to the arm of the wearer, should the snap become unfastened.
For this purpose a ribbon of spring steel, a piece of watch spring for instance, is
passed through the pieces and sections, such ribbon having an initial curvature
causing the bracelet to tend to coil up on itself, non-elastic cords being also
threaded through the pieces to prevent twisting upon the steel spring and to connect
the whole together.
In the case of a "built up" bracelet made of two rigid halves hinged together
and each composed of a number of sections or pieces which are usually cemented
together or otherwise united, the steel spring or springs pass through the segments
in the manner above described, and across the hinge joint, the effect being to
secure the segments rigidly together and to prevent the halves opening out wide.
Reference is to be bad to the accompanying drawings which represent in figure 1
a bracelet made of separate pieces and in figure 2 a built up bracelet, both these
views being sections in two different planes. Figure 3 shows one of the pieces of
figure 1 and Figure 4.shows the hinge joint of figure 2 opened.
Referring to figures 1 and 3, a is the steel spring which in figure 1 passes loosely
through a central hole 6 drilled in all the pieces c of the bracelet, except the two
end ones c¹. d are the non-elastic cords (preferably of silk) passed through holes at
either side of the spring and secured by knotting their ends in the pieces next to the
end ones; the end pieces c¹ being respectively united to the adjacent pieces by pairs
of twisted wires e cemented into holes in the pieces, in the usual way of uniting
pieces of jet. The end pieces are provided with any suitable snap or other fastening.

page_text: With this construction, the spring is retained in place without being fastened to
the jet, the continuity of the bracelet being ensured by the cords. Instead of a flat
ribbon a steel wire of round section might be used.
Referring to figures 2 and 4, the segments c are drilled centrally to receive the
spring a which lies loosely in them as before and may be reinforced at the point
where it crosses the hinge joint by a second short piece of spring a¹. In this case
the cords are replaced by twisted wires e, each consisting of two wires twisted
together and cemented into the holes in the segments, these wires serving to firmly
unite together the segments of each half respectively; the spring which is
continuous from one end segment of the bracelet to the other, alone crossing the
hinge joint.
.
The segments composing each half of the bracelet are further united by being
cemented together at the joints.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is
1. The combination with a jet or other bracelet, whether composed of separate
bead like pieces, or whether built up of segments united together, of a steel spring
having a suitable curvature threaded through the pieces or segments, substantially
as and for the purpose specified.
2. In a bracelet composed of separate bead-like pieces or built up of segments
united together, the combination of a central steel spring and of one or two non-
elastic cords or wires, substantially as shown and described.
