Year: 1884

page_text: PROVISIONAL SPECIFICATION.
I, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of
53, Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent
Agents, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN ELECTRIC JEWELLERY AND ORNAMENTS," a communication to me from abroad
by Gustavo Trouvé of Paris-France, to be as follows:-
This Invention relates to electric jewellery and ornaments used for theatrical
decorations and for balls soireés, &c, whereby novel decorative effects are obtained
applicable, to all kinds of theatrical costumes and other stage accessories such as
diadems, crowns, girdles, bracelets, armlets, shields, sceptres, sandals, &c.
The distinguishing feature consists in intercepting the luminous rays which are
emitted by a small incandescent electric lamp by means of lenses either facetted or
not, or preferably by means of colored artificial gems or stones. The electric light
when thus refracted produces altogether novel effects both as regards brilliancy and
variety. The form of the several parts of which the jewellery is composed would vary
according to the kind of decoration required and the nature of the article to which
it is to be applied, and I will proceed to describe a few arrangements by way of
example with reference to the accompanying drawings, in which Figures 1, 2 and 3
show horizontal sections of jewels composed simply of a flat surface a composed of
gems in the form of facetted lenses behind which is placed the incandescent lamp c.
Where only a single face set with gems is employed as in this case, it is preferable
to place a reflector d behind the lamp c of any suitable form either plane as in
Figure 1, or parabolic as in Figure 2, or multifaced as in Figure 3. The gems may
be set and the lamp and reflector fitted in any suitable manner and the latter may
also be dispensed with if desired.
In Figures 1. 2 and 3 the several parts are shown as mounted in a holder b and
in Figures 4. 5 and 6 is shown another arrangement in which the incandescent
lamp b occupies the centre of a spherical holder a studded with gems d d d and
having a stone fof larger size mounted in a removable annular setting g serving to
close an aperture in the holder a or it may be otherwise fitted so as to enable it

cravat or garment by sewing but any other suitable means of attachment may bo
employed.
Figure 7 shows a jewelled ornament similar to the preceding but in which the
case or holder a containing the gems d is made in halves fitting together the upper
half forming a cap to enclose the lamp which is introduced from above. In Figures 4.
5. 6. 7 the reflector is omitted as it is of advantage to allow the light to play alike
upon all the gems instead of its being concentrated on a single point as in Figures 1.
2 and 3.
The electric current may be supplied to the lamp from any suitable source and
by means of conductors of any kind. For example, a portable battery may be
concealed in any portion of the dress of the wearer of the ornaments, or the latter
may be connected with a fixed source of electricity by means of flexible conducting
wires sufficiently fine to be invisible at any distance from the stage and arranged
so as not to impede the persons movements.
Further, in order to increase the effect produced by the luminous gems, thero
may be combined therewith mirrors or reflectors which multiply the effect and thus
simultaneously present to the spectator all the faces in the same mount. For this
purpose the arrangements shown in Figures 8. 9, 10 and 11 are preferably employed.
Figures 8 and 9 show respectively an elevation and section of a portion of a necklace,
waist belt, or bracelet having three series of gems each with five faces, thus pre-
senting the appearance of 15 luminous centres. a a are the electric lamps disposed
as before described at the centre of the ornament of which bb are the faces set with
stones or facetted lenses. cc are the mirrors or reflectors placed at an angle of
45° opposite each face so that a person placed opposite the wearer of the ornament
will perceive all the faces simultaneously by reflection as indicated by the parallel
lines representing luminous rays.
With three luminous centres each disposed in an ornament with five faces, fifteen
faces will be visible at one time, that is to say, three direct and twelve by reflection.
The reflectors may be mounted on the ornaments in any suitable manner and may
be more or less inclined and either planes or concave or convex.
Figures 10 and 11 show respectively a face view and section of an ornament

facets and c the reflectors.
By thus combining reflectors with the jewels multiple effects may be obtained
with but a small number of luminous centres which is of importance when the
ornaments worn by the same person are fed by a portable battery as in this case
only a limited number of luminous foci can be used and by the use of reflectors in
this manner multiple and powerful decorative effects are obtainable which would be
otherwise impossible. By increasing the dimensions of the ornaments it will be
evident that they may be applied in all kinds of decoration such as luminous globe
for lighting up theatrical scenery and other situations for illuminations and al
kinds of stage effects.

by Gustave Trouvé of Paris-France,) 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 electric jewellery and ornaments used for theatrical

and 3 show horizontal sections of jewels composed simply of a flat surface a

incandescent lamp c Where only a single face set with gems is employed as in

form either plane as in Figure 1, or parabolic as in Figure 2, or multifaced as in
Figure 3. The gems may be set and the lamp and reflector fitted in any suitablo
manner and the latter may also be dispensed with if desired.
In Figures 1, 2 and 3 the several parts are shown as mounted in a holder b, and
in Figures 45 and 6 is shown another arrangement in which the incandescent
lamp occupies the contre of a spherical holder a studded with gems d d d aud
having a stone f of larger size mounted in a removable annular setting g serving to
close an aperture in the holder a or it may be otherwise fitted so as to enable it to
be removed for the purpose of affording access to the lamp b. Holes h are also
provided in the holder a for facilitating the attachment of the ornament to a
cravat or garment by sewing but any other suitable means of attachment may be
employed.
Figure 7 shows
jewelled ornament similar to the preceding but in which the
case or holder a containing the gems d is made in halves fitting together, the upper
half forming a cap to enclose the lamp which is introduced from above. In
Figures 4. 5. 6. 7 the reflector is omitted as it is of advantage to allow the light to
play alike upon all gems instead of it being concentrated on a single point as in
Figures 1. 2 and 3.
The electric current may be supplied to the lamp from any suitable source by
means of conductors of any kind. For example, a portable battery may be
concealed in any portion of the dress of the wearer of the ornaments, or the latter
may be connected with a fixed source of electricity by means of flexible conducting
vires sufficiently fine to be invisible at any distance from the stage and arranged

facets and c the reflectors.
By thus combining reflectors with the jewels, multiple effects may be obtained
with but a small number of luminous centres, which is of importance when the
ornaments worn by the same person are fed by a portable battery, as in this case
only a limited number of luminous foci can be used and by the use of reflectors in
this manner, inultiple and powerful decorative effects are obtainable which would
he otherwise impossible. By increasing the dimensions of the ornaments, it will
be evident that they may be applied in all kinds of decoration, such as luminous
globes for lighting up theatrical scenery and other situations, for illuminations and
all kinds of stage effects.
In order that the luminous effects of the jewels may be produced at any moment
and for any length of time desired, I employ the commutator represented in
elevation in Figure 12, the circuit being broken and in central longitudinal section
in Figure 13, the circuit being closed. This commutator, which from its small
dimensions and simplicity of action may be easily carried by the person wearing
the luminous jewels, consists of an ivory tube a upon the outside of which flexible.

The commutator is shown in connection with two separate circuits g working
simultaneously, but the same arrangement may be applied to one, two, three or
more separate circuits. With this arrangement in the event of an accident to
one of the lamps in multiple arc, the others will continue to work without
interruption.
Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed I declare that what
I claim is:
1st The combination with a flat surface composed of gems of the same or different
colors, of an electric glow lamp c, holder 6 and reflector d, as described with
reference to Figures 1, 2 and 3.
2nd The combination of an electric glow lamp b enclosed within a holder a
studded with gems and f, with any suitable means of attachment for enabling
it to be worn as a button, scarf pin &c. as described with reference to Figures 4 to 7.

page_text: Bra The combination with gems in which is enclosed an electric glow lamp as
described, of mirrors or reflectors c. c placed at angles of 45° at either side of the
gém, as described with reference to Figures, 8 to 11 for the purpose specified.
4th The combination with this improved system of luminous jewellery of the
portable cominutator consisting essentially.of a tube of iron conducting material a,
conducting strips b, d and sliding ring fas described with reference to Figures 12
and 13 for the purpose specified.
