Improvements in the Method of Mounting or Setting Certain or
Various Designs or Articles of Jewellry or Coins in Brooches,
Breast Pins, Solitaires, and other similar Articles.
We EDWARD HENRY DURBAN of 29, Wills Street, Lozells, Aston, in the county of
Stafford, Jeweller, and WILLIAM NELSON LAST, of 15 Alfred Street Birmingham, in
the county of Warwick, Jeweller do hereby declare the nature of this invention to be
as follows:-
This invention relates to improvements in the method of mounting or setting certain
or various designs of Jewellry, such as special coins, medals or other artistic or
valuable fronts or patterns; and has for its object the mounting of such articles in a
manner that they may be readily removed, or reversed, or replaced by other suitable
articles or designs, and that may be applicable to brooches, breast pins, bracelets,
button fronts, solitaire fronts, watch guard pendants or other similar trinkets.
In describing the nature of my invention we will assume its application to the
mounting of coins, such for instance as are now known as Jubilee coins.
An ornamental frame or case is provided of any desirable metal or design, having
in its front a circular opening a little smaller than the coin to be mounted. At the
rear of this front a case or chamber is formed, which for circular coins, would be of a
circular form, and a little larger in diameter than the coin to be mounted, and of a
suitable depth or thickness to receive and accomodate the following:-In the chamber
we provide a circular disc, which would be about the size of the coin, and consequently
a little larger than the circular opening in the frame. Behind this disc, that is,
between the said disc, and the back of the chamber, we provide a spring or springs,
flat, involute, or spiral, which alway tends to press the aforesaid disc against the front
of the chamber. Immediately behind the front plate or frame, we cut a slot in the
side of the chamber, near or about half way around it, and of a corresponding
depth or width to the thickness of the coin, so that from the front we may press
back the disc into the rear part of the chamber, and then slide the coin in through
he slot in the side, until the latter is central, when the spring would force
the disc against the coin, and press the latter into the front frame, and hold it
here.

page_text: When it is desired to withdraw &c. the coin, the said coin would be pressed
inwards until opposite the slot, when it may be removed.
It will be readily seen that instead of the coin, any artistic or otherwise ornamental
article of a similar size may be substituted therefor.
Again. In the front of the disc, and at its centre we may form a screw hole, by
which ornamental fronts may be attached from the front, when such ornaments
would not admit of being passed through the slot.
Thus with an arrangement of this kind forming the base for a brooch, scarf pin,
button, solitaire, ear ornament, bracelet, pendant &c., the design or pattern may be
varied or interchanged at will.

We EDWARD HENRY DURBAN, of 29, Wills Street Lozells, Aston, in the County of
Stafford, Jeweller, and WILLIAM NELSON LAST, of 15, Alfred Street, Birmingham, in
the county of Warwick, Jeweller do hereby declare the nature of this Invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
For improvements in the method of mounting or setting certain or various designs
or articles of jewellery, or coins, in brooches breast pins, solitaires, and other similar
articles, to be as follows.
This invention relates to improvements in the method of mounting or setting
certain or various designs of Jewellery, such as special coins, medals, or other artistic
or valuable fronts, or patterns, and has for its object the mounting of such articles in
a manner that they may be readily removed, or reversed, or replaced, by other
suitable articles or designs, and that they may be applicable to brooches, breast pins,
bracelets, button fronts, solitaires, watch guard pendants, or other similar trinkets.
In describing the nature of our invention, we will assume its application to the -
mounting of coins, such for instance as are now known as Jubilee Coins.
We take a piece of wire of any desirable metal about the depth of the coin to be
mounted, we then make it circular, so that the coin will just pass through. See
Fig. A.
We then make another circular wire which we flatten a little, and then solder it
inside the other circular wire aforesaid, which would then form the ledge to prevent
the coin passing right through, see Fig. B. We then proceed to ornament the frame
to any desirable pattern, for instance soldering shots on the edge, see Fig. Cor
making gaps in the edge, see Fig. D. We then proceed to make two pieces of tube,
see Fig. E, and then two small blocks or props, which we solder on the back of the
frame, see Fig. F. We then solder the tubes on the top of the blocks or props which
will then form the rests for the Spring, see Fig. F.
To make the spring which is one of the principal parts of our invention, we provide
a piece of thinish round wire and wind it on a round spit at each end, first right and
then left, leaving a portion unwound between, also a little to spare at ends, we
then put it into shape which makes the spring, see Fig. G.
We then take the spring and put into the space between the tubes and blocks,
and then put a wire pin through the tube and spring, when the end pieces would
press on the blocks, and so give the desired spring, see Fig. H.
But we do not want to bind ourselves to this kind of spring to attain our object, as
for instance we could use a flat spring with the same effect, see Figs. I and J.
We will then suppose it is wanted as a brooch, the joint & catch is then soldered on
the back of frame, which would then complete the article.

page_text: But instead of going to all this trouble of makeing them by hand as we have
hitherto described, we could have dies and tools inade, to stamp them which
however would only have the same effect, but thereby save a lot of work.
To place the coin in the frame the spring is pressed inwards from the front, and
then slide the coin from the back under the spring, until the coin is central sce
Fig. K, when the spring would hold the coin to the front of the frame, see Fig. L.
When it is desired to withdraw the coin it must be pressed inwards from the front,
when it can easily be removed from the back.
f
Or instead of the coin any valuable front, or pattern, or design, or ornament of
any shape, as aforesaid, may easily be replaced in the same manner.

The Fig. N is the section.
It will be readily seen that we have improved our invention, since the acceptance
of our provisional specification, by doing away with the back part of chamber and
by so doing decreasing its bulk and work.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is.
The method of mounting or setting certain of various designs, ör articles of
jewellery, or coins, or medals, in brooches, breast pins, bracelets, solitaires, and other
similar articles by the means of a spring from the back, which holds the coin, or
medal, or ornament, in the required position and that they may be removed, or
reversed, or replaced when desired without injury to them.
