PROVISIONAL SPECIFICATION.
Improvements in Electrical Ceiling Roses.
We, THOMAS GEORGE POOLE Electrical Engineer and WOODHOUSE AND
RAWSON UNITED LIMITED Electrical Engineers and Contractors all of 88 Queen
Victoria Street in the City of London, do hereby declare the nature of this inven-
tion to be as follows:-
-
Our invention relates to an improvement in that class of ceiling rose in which a
pillar, having longitudinal grooves, springs from the centre of the base.
Our improvement consists in forming an additional groove round the circum-
ference of the pillar, in such a position near to its top, that an elastic ring of any
suitable material may be sprung into it outside the lead wires, holding them tightly
in position, and on screwing down the cover the ring is further compressed and
forms a joint to the cover; in this way any wear and tear there may be, is borne
by the said elastic ring and not by the insulating covering of the lead wires.
The base has the usual metal plates for attachment of the different wires.
Dated this 18th day of October 1892.

COMPLETE SPECIFICATION.
Improvements in Electrical Ceiling Roses.
We, THOMAS GEORGE POOLE and WOODHOUSE & RAWSON UNITED,
LIMITED, all of 88 Queen Victoria Street in the City of London, Electrical
Engineers, 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 :-
Our invention relates to an improvement in that class of ceiling rose in which a
pillar having longitudinal grooves springs from the centre of the base.
Our improvement consists in forming an additional groove round the circum-
ference of the pillar in such a position near its top that an elastic ring of any
suitable material may be sprung into it outside the lead wires holding them tightly
in position and in screwing down the cover the ring is further compressed and forms
a joint to the cover; in this way any wear and tear there may be is borne by the
said elastic ring, and not by the insulating covering of the lead wires.
In the accompanying drawings,
Fig. I is vertical section of the ceiling rose with the cover removed.
Fig. II is a similar section with the cover in position.
Fig. III is a plan of the base.
Like letters refer to similar parts in each.
The pillar A has longitudinal grooves a¹ and near the top a horizontal groove
into which an elastic ring fits as shown in section in Fig. II. This ring is slipped
into position over the lead wires which lie in the grooves a¹.
When therefore the cover is screwed on the ring is gradually compressed by the
slightly conical face at D, and the ring remaining firm there is no tendency to
abrade the lead wires.
In Fig. III G1 G2 G 3 are metal plates the fuse being fixed between G 1 & G 3,
and the lead wires passing through the holes E 1 & E 2 in the base are attached
to G & G 1 in the nonal wow

page_text: Having thus particularly described the nature of our said invention, and the
way in which the same is to be performed we declare that what we claim is,―
A ceiling rose having a groove round and near the top of its central pillar
substantially as described and for the purposes set forth.
