I, WILLIAM JACKSON, of Birmingham, in the County of Warwick,
Jeweller, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN LOCKETS, BROOCHES, BRACELETS, AND OTHER LIKE ORNAMENTS,
AND ORNAMENTAL FASTENINGS," to be as follows:-
In constructing a locket according to my Invention I form it of two
parts or shells, but instead of connecting the two parts together by a
hinge joint as usual, I provide the two parts with the additions
herein-after described, whereby they can be securely connected together.
In the part constituting the body of the locket, that is, the part
having a ring by which the locket is suspended I place a steel or other
spring, the said spring having the general figure of a semi-ellipse; the
extreme ends of this spring are turned at right angles; this spring is
inserted underneath a flange passing round the face of the locket, the
turned ends of the spring passing out at openings at opposite points in
the flange described.
The insertion of that part of the locket called the box secures the
spring in its place. The other part or front of the locket has a similar

page_text: flange to that described with reference to the body of the locket, and
holes are made in the said flange at points corresponding to the
openings in the flange of the body of the locket at which the ends of
the spring project. By applying the inner face of the front of the
locket to the body in such a position that the ends of the spring are
presented to and enter the holes in the flange of the front part, and
gently pressing the two parts together, the front becomes securely
engaged with the back or body of the locket. The ends of the spring
being slightly inclined from one another there is a slight compression of
the spring as the front part is pressed upon the body of the locket, the
spring expanding into its normal shape when the front lies closely upon
the body.
In order to separate the front from the body of the locket it is only
necessary to apply the thumb nail to a small projection formed on the
top of the front, and gently to press the front from the body of the
locket held by the other hand; when the resistance of the spring is
overcome its ends are withdrawn from the holes in the front, and the
two parts are separated.
By the method of construction described the front of the locket
containing a miniature or other memento may be readily detached from
the body for the purpose of examination. Further, several fronts may
be applied from time to time to the same body. The absence of the
ordinary hinge joint permits of greater variety of ornament in the lockets
than is possible when the binge joint is used.
The front or central ornaments of brooches, bracelets, and other like
ornaments and ornamental fastenings, may be connected to the brooch
or bracelet or other article in the manner described with respect to a
locket. My Invention permits of the adaptation of several ornamental
fronts to these articles, and makes it easy to carry a miniature or other
memento in the ornament of a brooch, bracelet, or other article.
Although I have described my Invention as applied to a locket of the
ordinary elliptical figure, yet my Invention is not limited to lockets or
articles of any particular figure.
