IMPROVEMENTS IN FASTENINGS FOR BRACELETS AND SCARF RINGS
Year: 1884

page_text: We EDWIN RICHARDSON and ROBERT HALL of Birmingham in the County of
Warwick Jewellers do hereby declare the nature of the said Invention for
IMPROVEMENTS IN FASTENINGS FOR BRACELETS AND SCARF RINGS to be as
follows:-
This Invention consists in forming the fastening for band bracelets and scarf
rings by means of a grooved tongue piece on the one part of the article engaging
in a flanged slot in the corresponding part. This will be understood by reference
to the accompanying Drawings made to an enlarged scale in which Fig. 1 shews in
place the tongue piece upon one part of the article Fig. 2 a side view of same
Fig. 3 an end view of the slot upon the corresponding part and Fig. 4 a section
of the same upon the line A. B. The action is as follows the parts of the article
are turned out of line with each other until the tongue will enter the broader
part of the slot and spring into the narrower part whence it is prevented from
accidentally escaping by means of the flanges upon the slot engaging in the
grooves on the neck of the tongue.

We EDWIN RICHARDSON and ROBERT HALL of Birmingham in the County of
Warwick Jewellers do hereby declare the nature of our said Invention for
IMPROVEMENTS IN FASTENINGS FOR BRACELETS AND SCARF RINGS and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement, reference being had to the Drawings hereunto
annexed and to the letters and Figures marked thereon that is to say :-
This Invention consists in forming the fastening for band bracelets and scarf
rings by means of a grooved tongue piece on, the one part of the article engaging
in a flanged slot in the corresponding part the engagement of the clasp and its
power of being effectually secured and released being attained by the natural
spring of the hoop form in which the article is made, this will be understood by
reference to the accompanying Drawings which are made upon an enlarged scale
with the exception of Figure 5. which is bracelet size and in which Drawings
Figure 1 shews the tongue piece upon one half of the hoop as at, a, Figure 2,
a side view of the same Figure 3 an end view of the slot as at, b, upon the
corresponding part and Figure 4 a section of the same upon the line A B.
The action is as follows-Bringing the parts of the hoop together slightly out
of line sideways the one with the other the tongue piece, a, in Figures 1 & 2, can be
inserted into the broader part of the slot, b. Figures 3 & 4. when the natural spring
of the parts forming the hoop will return the two parts into a line with each other
and bring the tongue piece, a, into the narrower part of the slot from which it is
prevented escaping by means of the flanges, c, upon the slot as shewn in Figure 4.
closing into the groove, d, upon the tongue piece as shewn in Figures 1 & 2.
Pressing the parts of the hoop again out of line with each other brings the
tongue piece into the broader part of the slot and allows the hoop to be opened.
Figures 5. 6. 7. 8. & 9. represent a form of hoop in which the clasp or fastening
is gained by the upward instead of the sideways spring of the one part upon the
other, the hoop forming an incomplete circle when released as seen in Figure 5.
In clasping a hoop of this form the extended half e Figure 5. is slightly pressed
inwards and the tongue piece, f, Figures 7 & 9 being inserted into the slot, g,
Figures 6 & 8. the spring of the extended part, e, in its natural return causes the
groove, h, on the tongue piece to engage with the upper edge, i, Figure 8. of the
slot, g, thus locking the parts together, compressing the extended half, e, of the
hoop inwards the tongue piece is released and the parts of the hoop can be opened.
In either of these forms described the action of engaging and releasing the
fastening is obtained by the natural spring of the parts forming the hoop and
without the intervention of any spring upon the tongue piece or upon any other
part of the clasp.
Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed, we declare that what
we claim is, The improvements in fastenings for bracelets and scarf rings by which
the engagement and release of the parts is attained by the natural spring of the
hoop form of the article as in manner herein more fully set forth and specified.
