AN IMPROVED FASTENING FOR BRACELETS, EARRINGS AND KEY RINGS
Year: 1884

page_text: We FRIEDRICH WILHELM FUCHS, and FRIEDRICH GEORGE HEYNEMANN, both.
of 4, Great Pulteney Street, Golden Square, London, Manufacturing Jewellers and
Goldsmiths, do hereby declare the nature of the said invention for "AN IMPROVED
FASTENING FOR BRACELETS, EARRINGS AND KEY RINGS," to be as follows:-
Our Invention has for its object to provide a simple and secure snap fastening for:
bracelets, earrings and keyrings.
The fastening depends for its operation on the elasticity of the bracelet or other
ring to which it is applied and is therefore only adapted for such as by their
construction will admit of being sprung sufficiently to engage and disengage the
fastening.
The fastening consists of a keyhole-shaped frame attached to one end of the
bracelet &c to be united and to the back of any suitable ornamental device by
pillars and by the return outer ends of its parallel portion, and of a flat disc like
head attached to the other end of the bracelet &c: by a neck extending from one
face and edge of the disc.
The disc is adapted to pass through the circular part and the neck to lie in the
narrow parallel portion of the keyhole-shaped frame the disc presenting laterally
projecting portions or shoulders which are imprisoned beneath the parallel portion
of the frame and abut against the return outer ends thereof, when the one part of
the fastening is sprung into the other as above described.

We FRIEDRICH WILHELM, FUCHS and FRIEDRICH GEORGE HEYNEMANN both
of 4 Great Pulteney Street Golden Square London, Manufacturing Jewellers and
Goldsmiths, do hereby declare the nature of the said invention for "AN IMPROVED
FASTENING FOR BRACELETS EARRINGS AND KEY RINGS," and in what manner the
same is to be performed, to be particularly described and ascertained in and
by the following statement:-
Our Invention has for its object to provide a simple and secure snap-fastening for
bracelets, earrings and keyrings.
The fastening depends for its operation on the elasticity of the bracelet or other
ring to which it is applied and is therefore only adapted for such as will admit of
being sprung sufficiently to engage and disengage the fastening.
Reference is to be had to the accompanying drawings forming part of this
Specification wherein we have represented two examples of our improved fastening
as applied to a bracelet of the kind known as a "bangle" and made of wire of
round section, but. we, would have it understood, that it is equally applicable to
bracelets of other kinds and to other articles as before mentioned provided they
possess. the requisite elasticity. Figure 1 is a side view of the fastening in the
closed or locked position. Figure 2 is a plan view of the same the ornamental
Betting being removed to show the interlocking parts composing the fastening.
Figure 3 is a perspective view showing the same parts in the open or disengaged
position.
Figure 4 shows an underside view of a slight modification in the form of the
parts.
The same letters of reference indicate the same or similar parts in all these
figures..
The fastening consists on the one hand of a key-hole shaped frame a attached
ât o to one end of the bracelet b (or earring or key-ring as the case may be) and on
the other hand of a flat disc-like cross-head & attached to the other end of the
bracelet or other article b.
The keybole shaped frame consists of a circular portion a, of a diameter to admit
of the disc d passing freely through it and of two parallel portions a¹ turned
upwards and backwards at the extremities forming the return ends a³, the space
between the parallel portions a¹ being just sufficient to admit between them the
bracelet & a or in the case of a broad bracelet the narrow neck or stem by which
the head'd would in that case be attached to the bracelet. This frame a is open at
the under or rear side and is closed and concealed at the upper side by any suitable
ornament e to the setting or bezel of which it is attached by short pillars or studs f
and by soldering or otherwise to the return ends à' and points a¹. The disc or
crosshead d is soldered to or formed on the other end of the bracelet so as to present
two laterally projecting shoulders which are imprisoned by the parallel portions a¹
of the frame and abut against the return ends a³ when the one part of the fastening
iB sprung into the other, as shown in figure 2, the point of junction between the

page_text: head d and bracelet a being preferably at the under or rear side of the head so as
to form a neck which lies in the gap between the parts a' as shown in figures 1
and 2.
.
The natural tendency of the parts is to assume the relative position shown in
figure 3 and when by compressing the bracelet the head d is introduced (at the
underside) through the circular part of the frame it springs outward, owing to the
elasticity of the bracelet or other article, and occupies the position shown in
figures 1 and 2 wherein it is securely imprisoned within the frame a and cannot
become disengaged therefrom except by compressing the bracelet &* as before.
In figure 4 the disc d is in the form of a cross-bar and the frame a is a circular
ring having a gap and inwardly turned flanges a¹ between and behind which the
cross-bard engages as before.
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
A fastening for bracelets, earrings, and key-rings, consisting of a key hole-shaped
frame on the one end and a disc or crosshead on the other end to be united, these
two parts being constructed and adapted to be engaged together substantially as
herein described and shown in the drawings.
