"IMPROVEMENTS IN FASTENINGS FOR BRACELETS, NECKLETS, SCARF RINGS, AND
LOCKETS.".
My Invention consists in constructing and arranging in the manner herein after
described the parts of bracelets, necklets, scarf rings, and lockets, whereby a simple,
safe, and efficient double snap fastening is produced.
I will describe my Invention as applied to the fastening of a bracelet made in
two parts or halves jointed together. On the back or inside of one half of the
bracelet two spring arms are fixed, the end of each spring arm being furnished with
a flat bolt or catch, the said bolts or catches projecting from the meeting face or
end of the half of the bracelet carrying the said spring arms. The said bolts or
catches are situated parallel to one another, their inner ends overlapping. A
compound bolt is thus formed which expands and contracts by the sliding of the
parts over one another. The outer or most distant edges of the two bolts are
curved, the curved edge of each bolt joining the outer edge of its stem by a
shoulder; to each bolt a cross pusher is connected, the ends or heads of the said
pushers projecting from the edges of the bracelet. By pressure upon the heads of
the pushers by the thumb and finger they are simultaneously forced inwards, and
the compound bolt contracts by the parts sliding over one another.. When the
pressure is removed from the pushers the compound bolt expands by the clasticity
of its spring arms.
The meeting face or end of the other half of the bracelet is formed with an

page_text: oblong slot or opening. The compound bolt described passes through this slot and
engages under its ends by a snapping action.
In order to fasten the bracelet the meeting faces of the halves of the bracelet are
.brought together. As the compound bolt enters the slot or opening its parts close
or contract upon one another by their curved edges coming against the ends of the
said slot or opening, and when the two meeting faces of the bracelet come together
the shoulders of the compound bolt snap under the ends of the slot or opening and
effect the secure fastening of the bracelet. To unfasten the bracelet the two
pushers are pressed inwards between the thumb and finger. The compound' bolt
contracts by the sliding of the parts upon one another, and the shoulders of the said
bolt are removed from under the ends of the slot or opening, and the bracelet is
unfastened, the half provided with the slot or opening separating or opening from
the other half by means of a spring acting on its heel in the ordinary way.
The two spring arms carrying the compound bolt, and the spring for opening the
bracelet when unfastened may be made in one piece.
By my Invention the unfastening of the bracelet can only be effected by the
simultaneous pressing inwards of the two pushers, hence great safety in the
fastening is obtained.
I apply my Invention to the fastening of necklets and scarf rings in the manner
described with respect to a bracelet fastening.
In applying my Invention to the fastening of lockets I modify the parts in the
following inanner :-
Instead of making a compound bolt on the ends of the spring arms I make the
arms themselves act as bolts for effecting the fastening, the extreme ends of the
spring arms projecting from the edge of one half of the locket, and having heads.
An opening is made in the inner face of one half of the locket, near the free ends of
the spring arms, and on the opposite inner face of the other half of the locket a
forked staple or catch is made. When the halves of the locket are closed upon one
another the forked staple on one half enters the opening in the other half, and
presses the free ends of the spring arms together. On the complete closing of the
locket the said spring arms open outwards by their elasticity, and snap under the
branches of the forked staple, and thereby effectually fasten the locket. To
unfasten the locket the ends of the spring arms, external to the locket, are pressed
together, so as to remove them from under the forked staple when the locket is
unfastened and the halves separate by the action of a spring.

"IMPROVEMENTS IN FASTENINGS FOR BRACELETS, NECKLETS, SCARF RINGS, AND
LOCKETS."
My Invention consists in constructing and arranging in the manner herein after
described the parts of the fastenings of bracelets, necklets, scarf rings, and lockets,
whereby a simple, safe, and efficient double snap fastening is produced.
I will first describe my Invention as applied to the fastening of a bracelet made
in two parts or halves jointed together. On the back or inside of one half of the
bracelet two spring arms are fixed, the end of each spring arm being furnished with
a flat bolt or catch, the said bolts or catches projecting from the meeting face or end
of the half of the bracelet carrying the said spring arms. The said bolts or catches
are situated parallel to one another, their inner ends overlapping. A compound
bolt is thus formed which expands and contracts by the sliding of the parts over
one another. The outer or most distant edges of the two bolts are curved, the
curved edge of each bolt joining the outer edge of its stem by a shoulder or by a
notch. To each bolt a cross pusher is connected, the ends or heads of the said
pushers projecting from the edges of the bracelet. By pressure upon the heads of
the pushers by the thumb and finger they are simultaneously forced inwards, and
When the
the compound bolt contracts by the parts sliding over one another.
pressure is removed from the pushers the compound bolt expands by the elasticity
of its spring arms. The meeting face or end of the other half of the bracelet is
formed with an oblong slot or opening. The compound bolt described passes through
this slot, and engages with its ends by a snapping action.
In order to fasten the bracelet the meeting faces of the halves of the bracelet are
brought together. As the compound bolt enters the slot or opening its parts close
or contract upon one another by their curved edges coming against the ends of the
said slot or opening; and when the two meeting faces of the bracelet come together
the shoulders or, notches of the compound bolt snap under or engage with the ends
of the slot or opening, and effect the secure fastening of the bracelet. To unfasten
the bracelet the two pushers are pressed inwards between the thumb and finger.
The compound bolt contracts by the sliding of the parts upon one another, and the
shoulders or slots of the said bolts are removed from the ends of the slot or opening
in the half of the bracelet, and the bracelet is unfastened, the half provided with
the slot or opening separating or opening from the other half by means of a spring
acting upon its heel in the ordinary way.
The two spring arms carrying the compound bolt, and the spring for opening the
bracelet when unfastened, may be made in one piece.
I apply my Invention to the fastening of necklets and scarf rings in the manner
described with respect to a bracelet fastening.
In applying my Invention to the fastening of lockets I modify the parts in the
following manner-Instead of making a compound bolt on the ends of the spring
arms I make the arms themselves act as bolts for effecting the fastening, the
extreme ends of the spring arms projecting from the edge of one half of the locket,
and having heads. An opening is made in the inner face of one half of the locket,
near the free ends of the spring arms, and on the opposite inner face of the other
half of the locket a forked staple or catch is made. When the halves of the locket
are closed upon one another, the forked staple on one half enters the opening in the
other half, and presses the free ends of the spring arms togetlier. On the complete
closing of the locket the said spring arms open outwards by their elasticity and
snap under the branches of the fork staple, and thereby effectually fasten the locket.
To unfasten the locket the ends of the spring arms external to the locket are

page_text: pressed together, so as to remove them from under the forked staple when the locket
is unfastened, and the halves separate by the action of a spring.
I will now proceed to describe, with reference to the accompanying Drawing, the
manner in which my Invention is to be performed.
Figure 1 represents in elevation, and Figure 2 in elevation, partly in cross
section, a bracelet provided with a fastening made according to my Invention, the
said bracelet being closed and fastened in its closed position; Figure 3 represents
the same view as Figure 2, with the bolts or catches forced inwards, and made to
overlap one another for unfastening the bracelet; Figure 4 represents in elevation
the bracelet open; and Figure 5 represents the same partly in section; Figure 6
represents an edge view of the open bracelet.
The same letters of reference indicate the same parts in Figures 1, 2, 3, 4, 5,
and 6.
a, b, are the two parts of the bracelet hinged or jointed together at c; inside the
half or part a two spring arms d, d, are situated, the said spring arms d, d, being
made, by preference, in one piece, with the spring d², the tail or heel end of which
passes under the joint c, and serves to open the bracelet when unfastened (see
Figure 6). The outer end of each spring arm d is furnished with a flat bolt or
catch e projecting from the meeting face or end of the part a of the bracelet. The
said bolts or catches e, e, are made, by preference, in one piece with the spring
arms d, d, and the said bolts are situated parallel to one another, their inner parts
slightly overlapping when in their slot or normal position.
The said two bolts or catches e, e, constitute à compound bolt, which expands
and contracts by the sliding of the parts over one another. The outer edge of each
bolt e is curved as represented, and is provided with a shoulder or notch at f for
engaging with the ends of the opening in the other part 6 of the bracelet, as herein
after explained. To each bolt é a cross pusher 9 is connected. The heads of the
said pushers g, g, project from the edges of the bracelet, as seen in the several
Figures of the Drawing. When the heads of the pushers g, g, are pressed upon by
the thumb and finger the said pushers are simultaneously forced inwards, the
bolts e, e, sliding over one another as seen in Figure 3. On removing the pressure
from the heads of the pushers the compound bolt é, e, expands by the elasticity of
its spring arms d, d, and the parts of the said bolt take the positions represented in
Figures 2, 4, and 5.
In the meeting face or end h, h, of the half b of the bracelet is an oblong slot i of
a size proper for the contracted compound bolt e, e, to pass through for fastening or
unfastening the bracelet.
When the bracelet is to be unfastened the meeting faces or ends of the two
halves a, b, are brought together. As the compound bolt e, e, in the half a enters
the opening in the other half b the two parts of the said bolt close or contract
upon one another by their curved sides coming against the ends of the said opening i,
and when the two meeting ends of the bracelet come together the notches at f, f, in
the two parts of the bolt snap upon the ends at h, h, of the opening i, and effect the
secure fastening of the bracelet, as illustrated in Figures 1 and 2. When it is
wished to unfasten the bracelet the two pushers g, 9, are pressed inwards between
the thumb and finger. The compound bolt e, e, is thereby closed or contracted, and
the two parts made to occupy the positions represented in Figure 3; the shoulders
or notched parts f, f, are thereby withdrawn from the ends of the opening i, and
the two parts a, b, of the bracelet are unfastened, the two parts separating from one
another by the action of the heel of the spring d², as represented in Figures 4, 5,
aud 6.
By my Invention the unfastening of the bracelet can only be effected by the
simultaneous pressing inwards of the two pushers, hence great safety in the
fastening is obtained."
The fastening described and represented in Figures 1, 2, 3, 4, 5, and 6, is
applicable to bracelets of all kinds, and also to necklets and scarf rings.
Figure 7 represents in end elevation, and Figure 8 in longitudinal section a

page_text: locket provided with a fastening constructed according to my Invention, the locket
being represented fastened; Figure 9 represents the locket open; Figure 10
represents in elevation, partly in section and in plan, portions of the locket fastening
drawn to a larger scale.
The said fastening consists of two spring arms k, k, the free ends of which project
from the edge of the half of the locket. The edge of the said part 7 is cut away
at P, and in the said cut away part the ends of the spring arms are situated; on
the opposite edge of the other half m of the locket is a forked staple or catch g,
having the shape best seen in Figure 10. The inner faces of the branches of the
said forked staple q are inclined at r, r. When the two parts l, m, of the locket are
closed upon one another the forked staple q on the part m enters the opening or
cut away part p in the other part t, and the inclines r, r, of the said staples q press
the free ends of the spring arms k, k, inwards or together. After the inclined
heads r, r, of the staple have passed the spring arms k, k, and the closing of the
locket has been completed, the said spring arms open outwards by their elasticity
and snap under the heads r, r, of the branches of the forked staple q, and thereby
very securely fasten the locket, as best seen in the enlarged views Figure 10. By
pressing together the heads on the external ends of the spring arms k, k, the
said arms are withdrawn from under the forked staple q, and the locket is
unfastened, and the two parts l, m, of the locket separate by the action of the heel
of the prolonged part 2 of the spring arms le, k.
Having now described the nature of my Invention, and the manner in which
the same is to be performed, I wish it to be understood that I claim as my
Invention,
First. The improvements in fastenings for bracelets, necklets, and scarf rings,
herein before described, and illustrated in Figures 1, 2, 3, 4, 5, and 6, of the
accompanying Drawing, that is to say, a fastening consisting essentially of the
compound bolt or catch e, e, capable of expanding and contracting by the sliding of
the parts over one another, in combination with the cross pusbers g, g, for releasing
the said compound bolt or catch, the said compound bolt or catch fastening and
unfastening the bracelet, necklet, or scarf ring, substantially as described and
illustrated.
Secondly. The improvements in fastenings for lockets, herein before described and
illustrated in Figures 7, 8, 9, and 10 of the accompanying Drawings, that is to say,
a fastening consisting of a pair of spring arms k, k, on one part of the locket
engaging with a forked staple q on the other part of the locket, the said spring
arms engaging with the forked staple, and being disengaged therefrom, substantially
as described and illustrated.
In witness whereof, I, the said Joseph Tranter, have hereunto set my hand
and seal, this Second day of May, in the year of our Lord One thousand
eight hundred and seventy-nine.
