improvements in or relating to Articles of Jewellery.
A communication from WILHELM Iнм of Hanau-on-the-Maine, in the Empire of
Germany.
I, WILLIAM FELDENHEIMER of 21 Holborn Viaduct in the County of Middlesex,
Diamond Merchant 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:―
This invention relates to articles of jewellery, and has for its object the con-
struction of a brooch which may at will be taken to pieces and converted into a
ring and brooch separately.
In the accompanying drawings
Figure 1 is a perspective view of the convertible brooch,
Figure 2 is a perspective view of the bar of the brooch after the ring has been
detached,
Figure 3 is a perspective view of the ring when detached and adjusted for wear.
Figure 4 is a section of the ring on the line 4-4 of Fig. 3, the jewel mounting
being turned into a plane at right angles to that shown in Fig. 3.
Figure 5 is a perspective view of the ring with the jewel mounting detached.
Like letters indicate like parts throughout the drawings.
The brooch comprises a bar A provided with the usual hinged pin B and hook A',
and a ring C carrying the jewels in a mounting D which is adjustable in position.
relatively to the ring C; that is to say the mounting may be so turned
that the jewels E may lie either in a plane approximately parallel
to that of the ring C, when the latter is attached to the bar A
or in a plane approximately at right angles to
the plane of the
ring C when it is required to wear the latter in the usual way. In order to
obtain the adjustable connection between the ring and the jewel mounting, the ring
is formed of a piece of metal with a certain amount of spring in it bent into a
circle, its ends being provided with pins C, which engage with holes D₁ in the
mounting D forming a pivot about which the latter 'may be turned. The ends of
the piece of metal forming the ring C are also provided with projections C³
arranged at right angles to each other, conveniently in the form of a cross, as
shown in Fig. 5, corresponding crossed grooves D2 being formed on each side of
the mounting D. With this arrangement it will readily be seen that when the
mounting D is in position between the ends of the metal ring C the stones may be
turned into various planes at right angles to each other and retained in the desired
position by reason of the engagement of the projections C with the grooves B2,
the spring of the metal allowing the ring C to open sufficiently to admit of the
projections being disengaged from the grooves when it is desired to alter the posi-
tion of the stones.
The method of attaching the ring C to the bar A so as to form the brooch
shown in Fig. 1 is indicated in Fig. 2. The bar A has at a convenient point
in its length a notch A³ cut in it, the notch being of sufficient size to admit and

page_text: fit the jewel mounting D of the ring. In this notch is fixed a pin A³ which
engages a hole D³ in the mounting D the latter also having a screw-threaded
hole D in it with which a screw A' may engage. The screw A4 is provided with a
reduced part where it passes through the notched part of the bar A, being pro-
vided on the other side with a head A5 and conveniently a hinged handle or flap A
to allow of its being readily turned. It will thus clearly be seen that in order to
take the complete brooch (as shown in Fig. 1), to pieces, it is necessary to unscrew
the screw A when the ring C may be detached from the bar A. In order that
the ring may then be arranged for wear the mounting D must be turned until
the stones lie in a plane at right angles to that of the ring C. If desired a
separate jewel mounting may be provided which can be attached to the bar A
in the same way as when it is required to attach the complete ring, thus providing
a brooch which may at will be converted into a brooch of another design and also
a ring.
It is obvious that the design of the brooch may be varied considerably, also"if"
desired the convertible ring may be arranged to be attached on to a pin for use as
a tie pin or the like.
The mounting D need not necessarily be formed solid in order to enable it to be
provided with the holes D3 and D, but is preferably constructed with a transverse
bar D in the substance of which these holes may be formed, as shown in Fig. 3.
It must be understood that the details of construction may be varied considerably
without departing from the spirit of the invention.
'
Having now particularly described and ascertained the nature of the said
invention as communicated to me by my foreign correspondent, I declare that what
I claim is
1. A combined ring and brooch.
2. A ring having the jewel adjustably mounted upon it for the purpose
described.
3. A. brooch and ring adapted to be used separately or in combination substan-
tially as described.
4. Uniting a ring and brooch in the manner and for the purpose described.
5. The combination with a ring such as C D of a detachable scarf pin substan-
tially as described.
6. The complete convertible article of jewellery substantially as described and
illustrated in the accompanying drawings.
