My invention relates to bracelets of that class which are made of gold or other
wire, and is designed to provide means whereby the said bracelets may be caused
to expand when passing over the hand of the wearer, either for putting them on or
taking them off the arm, and to contract to their proper size when strain is
removed, the object being to provide a bracelet which will have no open space
when expanded or otherwise so that all danger of the same becoming unfastened
or falling from the arm when worn is obviated.
In carrying the said invention into practice the wire is curved to the proper
shape and size, two ends being left which may be pulled apart, but which,'
whenever the strain is removed will come together again by, reason of the resiliency
of the wire. The latter is made tubular for a short distance from each of the said
ends and a piece of thinner wire, which has had given to it the proper curve, is
inserted in such a manner that the tubular part of the bracelet slides over this
inserted wire whenever the bracelet expands or contracts and thus prevents the
existence of any gap or opening. The ends of the inserted wire are provided with
suitable material, or otherwise treated, to prevent any chance of their coming out.
of the tube.
According to a modification of the said invention, instead of making the wire'
tubular and inserting a piece of thinner wire, I flatten the wire of which the
bracelet is made upon opposite sides along a short distance from each end, and
provide a small ring upon the said ends. The flattened parts of the wire slide
upon each other when expansion or contraction takes place and they are prevented.
from coming apart and leaving a gap, by the aforesaid rings.
Bracelets made as above described may be ornamented in any desirable manner.

ADOLPHE DESBATS, of Langham Street, in the County of Middlesex, Manu-
facturing Jewellor, "IMPROVEMENTS IN BRACELETS"
My invention relates to bracelets which are made of gold or other wire.
Bracelets of this kind have been heretofore made in the form of a ring or oval
provided with one or moro hinges or other means whereby the bracelet can be
opened or expanded to permit it to be passed around the wearer's wrist, and having
a suitable fastening to enable it to be secured thereon. But when these bracelets
are expanded, a gap or opening is formed between the ends of the wire; the said
bracelets are, therefore, liable to be accidentally unfastened and fall from the wrist
and thus be lost.
The object of my invention is to so construct a bracelet that it can be expanded
to enable it to be passed over the hand, either when putting it on or taking it off,
without destroying its continuity, and will then contract to its proper size and
thus fit or adapt itself to the wrist of the wearer.
By making a bracelet in this manner all-risk of the same becoming unfastened
and falling from the arm of the wearer is obviated.
In the accompanying drawing I have shewn how my said invention may be
conveniently and advantageously carried into practice.
Figure 1 is a plan or face view of one form or modification of my improved
bracelet, shewing the same contracted.
Figure 2 is a similar view of part, of the said bracelet, shewing the same
expanded.
Figure 3 is a plan or face view of another form or modification of my improved
bracelet, shewing the same contracted.
Figure 4 is a similar view of part of the said bracelet, showing the same
expanded, and
Figure 5 is an edge view of the same.
These Figures are all drawn to an enlarged scale.
A is the gold or other wire, which is curved to the proper shape and which, in
the form or modification shewn in Figures 1 and 2, is so made that its two ends
may be pulled apart, but whenever the strain is removed will come together again
by reason of the resiliency or elasticity of the wire. In the bracelet shown in
these Figures, the wire A is made tubular for a short distance from each end
thereof and a piece of thinner wire B, which is properly curved, is inserted therein
in such a manner that the said tubular parts will slide upon the wire B whenever
the bracelet expands or contracts. The ends of the wire B are provided with
projecting rims b and the tubular ends of the wire A are provided with rings or
internal projections a so that the bracelet can be expanded but its continuity
cannot be destroyed by withdrawing the wire B from the said tubular parts of
..the wire A.
According to the modification of my invention shewn in Figures 3, 4 and 5
instead of making the wire A tubular and inserting a piece of thinner wire therein,
I make the said wire of such length that when the bracelet is expanded the ends
of the wire will slightly overlap each other, and I flatten or reduce the thickness
of the wire from each end thereof to the points c as shewn in Figure 5. A small
ring d is fixed on each end of the wire A in such a manner that the ring on one
of the said ends surrounds the flattened or reduced part of the other end. When

page_text: the bracelet expands or contracts the flattened or reduced parts of the wire slide
upon each other through the rings d, but are prevented by the said rings from
coming apart and thus forming a gap or opening between them.
Bracelets made as above described may be ornamented in any desirable manner.
Having thus fully described my said invention and the manner of performing
the same I wish it understood that I claim
A bracelet formed substantially as set forth of gold or other wire in such a
manner that it can be expanded, without destroying its continuity, and contracted,
so that it may be conveniently passed over the hand and will then fit or adapt
itself to the wrist of the wearer.
In witness whereof I the said Adolphe Desbats have hereunto set my hand
and seal this Twentieth day of February in the year of Our Lord One thousand
eight hundred and eighty four.
