Improvements in Ceiling Roses for Electric Light Fittings.
I, FRANCIS WILLIAM BALL, Electrical Engineer, and JOHN HUGH WINTER,
both of 3, Unity Street, College Green, Bristol, in the County of Gloucester,
Electrical Engineer 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, and accompanying drawing, that is to say :-
Our invention relates to the ornamental ceiling roses to which are suspended
conducting wires carrying electric incandescent lamps. It has for its object
novel methods of constructing such ceiling roses, so that heavy pendants may be
conveniently carried by them, provided with lamps, shades, and fittings of
different kinds.
Where such ceiling roses have been used for carrying light flexible conducting
cords and incandescent electric lamps, it has been usual heretofore to screw a china
base to the ceiling, this base being provided with a shoe into which slides a
V-section piece of china, and to each of them metal plates are fixed in such manner
that when the V-piece is inserted in the shoe, proper contacts are made by which
the electric current is conveyed from conductors in the base through the shoe
and V-piece, to flexible conductors attached to the V-piece, and carrying an
electric lamp at their lower end.
An ornamental china cover screws upon the base and contains the shoe, the
V-piece, and the usual cut-out, the flexible conducting cords passing freely through
a hole in the centre of the bottom of the cover.
Our present improvements enable devices of the kind described to be applied to
heavier metallic pendants.
The accompanying drawing is in illustration of our invention, Figure 1 being a
vertical section, and Figure 2 a side view of the apparatus.
a, Figure 1, is the china base, which may be screwed to the ceiling by means of
screw holes at b.
c is the shoe in the base a, into which fits the V or dovetailed china piece d,
which is inserted into the shoe endways, in the usual way.
e, e¹ are metal contact plates attached to the shoe c and the V-shaped piece d
respectively, conducting wires passing from the latter to a pendant below,
Outside the base a we fit and screw firmly to the ceiling a brass or other metal
ring to the lower edge of which at 9 is screwed the upper edge of a hollow
ornamental metal case h, the lower part of which is provided with an opening
through which is passed a socket i upon the upper end of which is formed or fixed
a spherical flange k, the lower side of which rests upon a corresponding spherical
seat round the lower opening in the case h.
To the lower end of the socket i is screwed a metal or other tube or support
forming a pendant at the lower end of which are carried brackets and other fittings
for the incandescent lamps, the conducting wires for which pass freely from the
V-shaped piece d, and through the socket i and the tube or pendant below, but
without any weight or strain being placed upon them.
It will be seen that by the arrangement described, pendants, brackets, and lamps
of any desired weight may be suspended from the ceiling rose without risk, whilst
by unscrewing the case the V-shaped piece d, together with the contact piece
attached to it, (and cut-out, or fuse, if used), can be withdrawn from the shoe c
and instantly removed for repairs, adjustment, or any alteration that may be
necessary, and it can be replaced equally quickly and easily.

page_text: We do not confine ourselves to the precise details and shape of the several parts,
which may be varied more or less as may be found advisable in different
circumstances, but,
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 :-
:-
1. The combination with the shoe c, V-shaped piece d, and contact pieces e
and e', and conductors, of the metal ring, upon which is screwed the hollow metal
case h, carrying below a pendant, through which the conductors pass, and electric
lamps, substantially as and for the purpose described and illustrated.
2. In combination with the parts described and claimed in Claim 1, the socket i,
suspended by a universal joint at k to the case h, and having attached to it below,
the pendant through which the conductors pass, and electric lamps, substantially
as and for the purpose described and illustrated.
Dated this 28th day of March 1895.
