PROVISIONAL SPECIFICATION left by the said Emanuel Frederick Griffin
at the Office of the Commissioners of Patents on the 8th March 1881.
EMANUEL FREDERICK GRIFFIN, of Birmingham, in the County of Warwick,
Manufacturer. "IMPROVEMENTS IN FASTENINGS FOR BRACELETS, NECKLETS,
WAISTBANDS, SCARF SLIDES, AND OTHER LIKE ARTICLES."
My Invention consists of the combination or arrangement herein after described
of the parts of fastenings for bracelets, necklets, waistbands, scarf slides, and other
like articles.
My Invention is especially applicable to the fastening of bracelets consisting
of two jointed semi-elliptical halves, and I will describe it as applied to such
bracelets.
The fastening consists essentially of two sliding hooked bolts projecting from the
meeting face of one half of the bracelet, taking into and engaging with slots made
in the meeting face of the other half of the bracelet. The hooked ends of the bolts
are turned outwards and the stems of the said bolts work in slots in the meeting
face of the half bracelet carrying them. The two bolts are pressed outwards,
that is, are separated from one another by a coiled spring between them, the ends of
the coiled spring taking upon pegs on the bolts. Made in one piece with each bolt
is a pusher or releaser which projects through a hole in the edge of the bracelet.
On the bolt is a guiding piece at right angles to the pusher. These guiding pieces
on the bolts take into slots in a fixing plate situated at the back of the box or case
formed at the free end of the half bracelet for containing the fastening. By means
of these guide pieces working in the slots in the fixing plate in conjunction with
the stems of the hooked bolts working in the slots in the meeting face of the half
bracelet, the sliding motion of the bolts is made very steady and their parallelism
to the case in which they work preserved.

page_text: The hooked bolts are arranged and fixed in the case or box at the free end of
the half bracelet in the following manner:-The back of the case or box is open
and the hooked bolts, together with their pushers and spring, are passed into their
places from the said open back. A fixing plate having slots in it for the guiding
pieces on the bolt to work in, and having its ends turned at right angles, is next
placed in and made to close the open back of the box, the slots in the plate passing
over the guiding pieces on the bolts and the turned ends of the plate bearing
closely against the edges of the box. By soldering or rivetting the fixing plate,
by its turned ends to the edges of the box the bolts, pushers, and spring, are
secured in their places.
When the free ends of the half bracelet are brought together the projecting
hooked ends of the bolts on one half bracelet enter the slots in the face of the
other half bracelet, the said bolts being pressed together. On the complete closing
of the bracelet the shoulders of the hooked bolts snap upon or engage with the
edges of the slots described, and the two halves of the bracelet are fastened
together. By pressing upon the pushers the shoulders of the hooked bolts are
removed from the edges of the slots when the halves of the bracelet are unfastened
and may be separated.
For the purpose of preventing lateral motion in the halves of the bracelet during
the closing of the bracelet, a guiding peg on the face of one half bracelet may take
into a corresponding depression in the face of the other half bracelet. By means
of a spring at the bottom of the depression into which the guiding peg enters the
bracelet is made to spring open immediately the pushers are pressed upon by the
thumb and finger.
I apply my improvement to necklets, waistbands, scarf slides, and other like
articles, substantially as herein before described with respect to a bracelet
fastening.

EMANUEL FREDERICK GRIFFIN, of Birmingham, in the County of Warwick,
Manufacturer. IMPROVEMENTS IN FASTENINGS FOR BRACELETS, NECKLETS,
WAISTBANDS, SCARF SLIDES, AND OTHER LIKE ARTICLES."
My Invention consists of the combination or arrangement herein after described
of the parts of fastenings for bracelets, necklets, waistbands, scarf slides, and other
like articles.
My Invention is especially applicable to the fastening of bracelets consisting
of two jointed semi-elliptical halves, and I will describe it as applied to such
bracelets.
The fastening consists essentially of two sliding hooked bolts projecting from the
meeting face of one half of the bracelet, taking into and engaging with slots made
in the meeting face of the other half of the bracelet. The hooked ends of the bolts
are turned outwards and the stems of the said bolts work in slots in the meeting
face of the half bracelet carrying them. The two bolts are pressed outwards, that
is, are separated from one another by a coiled spring between them, the ends of the
coiled spring taking upon pegs on the bolts. Made in one piece with each bolt is a
pusher or releaser which projects through a hole in the edge of the bracelet. On
the bolt is a guiding piece at right angles to the pusher. These guiding pieces on
the bolts take into slots in a fixing plate situated at the back of the box or case
formed at the free end of the half bracelet for containing the fastening.
By means of these guide pieces working in the slots in the fixing plate in con-
junction with the stems of the hooked bolts working in the slots in the meeting
face of the half bracelet, the sliding motion of the bolts is made very steady and
their parallelism to the case in which they work preserved.
The hooked bolts are arranged and fixed in the case or box at the free end of the
half bracelet in the following manner :-The back of the case or box is open and
the hooked bolts, together with their pushers and spring, are passed into their places
from the said open back.
A fixing plate having slots in it for the guiding pieces on the bolt to work in and
having its ends turned at right angles is next placed in and made to close the open
back of the box, the slots in the plate passing over the guiding pieces on the bolts
and the turned ends of the plate bearing closely against the edges of the box. By
soldering or rivetting the fixing plate by its turned ends to the edges of the box
the bolts, pushers, and spring are secured in their places.
When the free ends of the half bracelet are brought together the projecting
hooked ends of the bolts on one half bracelet enter the slots in the face of the other
half bracelet, the said bolts being pressed together. On the complete closing of the
bracelet the shoulders of the hooked bolts snap upon or engage with the edges of
the slots described, and the two halves of the bracelet are fastened together.
By pressing upon the pushers the shoulders of the hooked bolts are removed from
the edges of the slots when the halves of the bracelet are unfastened and may be
separated.
For the purpose of preventing lateral motion in the halves of the bracelet during
the closing of the bracelet, a guiding peg on the face of one half bracelet may take
into a corresponding depression in the face of the other half bracelet.
I apply my improvements to necklets, waistbands, scarf slides, and other like
articles, substantially as herein before described with respect to a bracelet
fastening.
. I will now proceed to describe with respect to the accompanying Drawing the
manner in which my Invention is to be performed.
Figure 1 represents in side elevation, and Figure 2 in edge view a closed bracelet
provided with a fastening containing my improvements; Figure 3 represents

page_text: "
sections taken at right angles to one another of the two meeting faces of the halves
of the bracelet and the fastening drawn to a larger scale; Figures 4, 5, and 6
represent parts of the bracelet and fastening separately. The same letters of
reference indicate the same parts in Figures 1, 2, 3, 4, 5, and 6.
a, b, are the halves of the bracelet jointed together at c; d, d, are the sliding
hooked bolts pressed outwards by the coiled spring h between them. The heads of
the said hooked bolts project from the meeting face e of the half bracelet b, the
stems of the said bolts working in slots f, f, in the said meeting face e; g, g, are
slots in the meeting face of the half bracelet a through which slots g, g, the hooked
ends of the bolts pass, the shoulders of the said hooked ends engaging with the
edges of the said slots to fasten the two parts of the bracelet as illustrated in
Figure 3. The spring h which presses the two bolts d, d, outwards is supported
upon stalks on the said bolts; i, i, are the pushers made in one piece with the
bolts, the said pushers projecting through holes in the edges of the part 6 of the
bracelet. The projecting end of each pusher is covered by a cap. One of the bolts
and its pusher is represented separately in Figure 4. On each bolt d. is a guiding
piece situated at right angles to the pusher. These guiding pieces take into the
slots, 1, in the fixing plate m situated at the back of the box or case of the
half bracelet b. By means of these guiding pieces the sliding motion of the bolts
is made very steady and their parallelism to the case in which they work is
preserved, as will be understood by an examination of Figure 3. The box or case
at the meeting face of the half bracelet 6 containing the fastening is constructed of
the angular plate represented separately in Figure 5, and marked e and the fixing
plate m represented separately in Figure 6, each plate being slotted. The hooked
bolts d, d, and their spring h are passed into their places in the case e from
the open back, and the fixing plate m is next placed in and made to close the said
open back of the case, the guiding pieces h, k, on the bolts passing through
the slots 1, 1, in the said fixing plate m. The turned ends m, n, of the fixing plate m
bear against the sides of the bracelet and are secured thereto by soldering or
rivetting, as represented in Figure 3.
The meeting face of the half bracelet a is made of an angular plate similar to
the plate, Figure 5; p is the guiding peg on the half bracelet b, taking into a hole
in the other half bracelet a, for preventing lateral motion in the said halves during
the closing of the bracelet.
On closing the halves of the bracelet for fastening them, the projecting
hooked ends of the bolts d, d, on the half bracelet b enter the slots g, g, in the
meeting face of the other half bracelet a, the said bolts being pressed together,
and the spring between them.compressed by the inclined heads of the said
bolts bearing against the edges of the slots g, g. On the complete closing of
the bracelet the shoulders of the hooked bolts snap upon or engage with the edges
of the slots g, g, as illustrated in Figure 3, and the halves a, b, of the bracelet are
fastened together. To unfasten the bracelet the pushers i, i, are pressed inwards.
The shoulders of the hooked bolts d, d, are thereby removed from the edges of the
slots g, g, when the halves a, b, are unfastened and may be opened.
Instead of steadying the motion of the hooked bolts in and preserving their
parallelism to the case in which they work by the guiding pieces k, k, and fixing
plate m, the same objects may be attained by modifying the parts in the manner
illustrated in Figures 7, 8, 9, and 10, Figure 7 representing a side elevation, and
Figure 8 an edge view of a bracelet provided with the modified fastening, and
Figures 9 and 10 sections of a portion of the same taken at right angles to one
another, drawn to a larger scale; Figures 11, 12, 13, and 14, are parts of the
same separately.
In this modification I make the hooked bolts d, d, and pushers i, i, separate,
and connect them together by spring catches in the pushers. The pushers d are
tubular and square in cross section, and work in the square case q at the meeting
face of the half bracelet b. The case q is made by soldering the trough plate
represented separately in Figure 11 to the meeting face of the half bracelet b, as

page_text: seen in Figure 10. The meeting face of the half bracelet a is made of the angular
plate represented separately in Figure 12, and marked r. The separate hooked
bolts (one of which is represented separately drawn to a larger scale in Figure 13)
have inclines d at their bases and shoulders d³, and the separate tubular pushers i
have slots 2 in one face, as seen in Figure 14.
In each pusher i is a coiled spring i³, which presses outwards the fixing bar or
catch it, shown separately in Figure 13, the opening in the bar or catch i* coinciding
with the slot 2 in the pusher i. The springs and bar or catch are retained in
the pusher i by closing the open end by the cap 15.
In arranging the parts of the fastening in the case q of the half bracelet b, the
spring 8 by which the two bolts are pushed outwards is first placed in the case, and
afterwards the pushers i, i, containing the spring catches. The inclined ends of the
separate hooked bolts d, d, are passed through the slots q², q², in the case q and
pressed into the holes or slots 22 in the pushers, so as to cause the spring fixing
bars or catches 24 to engage with the shoulders d³ of the hooked bolts and fix them
in the said pushers. The bolts are thereby secured to the pushers, and the pushers
at the same time secured in the case q. As the pushers are square and the case in
which they slide has a corresponding figure, the said bolts are effectively guided in
their motion, and their parallelism in the case preserved. The hooked bolts d, d,
of the bracelet, Figures 7, 8, 9, and 10, when the halves a, b, of the bracelet are
closed, pass through and snap upon the edges of the slots ², 72, in the meeting
facer of the half bracelet a to fasten the two halves together, as described with
respect to the fastening represented in Figures 1, 2, and 3.
The guiding stud t may be made by raising it from the trough plate q,
constituting the case of the fastening.
Figure 15 represents a scarf slide containing a fastening constructed according to
my Invention.
I construct and arrange the parts of fastenings for necklets, waistbands, and
other like articles, substantially as herein described and illustrated with respect to
a bracelet and scarf slide fastening.
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, waistbands, scarf
slides, and other like articles herein before described and illustrated in Figures 1, 2,
3, 4, 5, and 6 of the accompanying Drawing, that is to say, providing the sliding
hooked bolts d, d, of the fastening with the guiding pieces k, k, and the combination
therewith of the slotted fixing plate m, n, for the purpose, and substantially as
described and illustrated.
Secondly. The modification herein before described and illustrated in Figures
7, 8, 9, 10, 11, 12, 13, 14, and 15 of the accompanying Drawing, in which tubular
pushers, square, or angular in cross section, are used, the said pushers being made
separate from the hooked bolts, and the latter connected to the pushers, sub-
stantially as described.
In witness whereof, I, the said Emanuel Frederick Griffin, have hereunto set
my hand and seal, this Nineteenth day of August, in the year of our Lord
One thousand eight hundred and eighty one.
