COMPLETE SPECIFICATION.
An Improved Ceiling-rose for Electric Lights and the like.
I, HERBERT FITZROY CLAYTON, of "Craigmhor," Huddersfield, in the County
of York, Manufacturer, 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 an improved ceiling rose for electric lights and the
like and has for its objects (1) to provide improved means of fastening the con-
nections from the lamp (or lamps) to the terminal screws on the base of the rose
so that the strain on the wires at that point is reduced to a minimum and conse-
quently the liability of fracture of the connection is also reduced, and, (2) to
provide a rose of high insulation.
I carry out my invention in the following manner, reference being made to
the accompanying drawing in whicb:-.
Figure 1 is a plan of my improved ceiling rose with the cover removed;
Figure 2 being a vertical cross section of the rose as fixed to the ceiling and with
the cover on.
The same letters refer to the same parts in the two figures.
a is the base of the rose bb¹ being the leading in terminals for the line wires
and the terminal screws for attaching the wires or connections from the
lamp to the rose. On the base a I provide a block or projecting piece d which
extends entirely across that portion of the base on which the terminal screws
are fixed, between said terminals, and which is considerably deeper or higher
than the terminal screws. In this block d on the rose base I provide a zig-zag
passage d' extending from end to end of the block as shown and forming con-
nection with the central hole e. The wires or connections from the terminal
screws cc to the lamp are passed through and lie in the passage d' as shown.
The exact method of running the wires or connections through the zig-zag
passage d¹ may be varied..
The zig-zag passage d' gives a grip on the wires and so relieves the ends con-
nected to the terminal screws c c of undue strain.
The passage in the block d on the rose base may be formed sloping or wedge
shaped on one or both of its sides to give an increased hold on the wires, and said
passage d may be open throughout its entire length either to the top or side of
The block d so that the connections from the lamp to the terminal screws c cl
may be simply pressed into position instead of being threaded through the
passage d¹.
The block or projecting piece d extending across the rose base as shown, gives
high degree of insulation.
It is obvious that my improved ceiling rose can be adapted for two or more
amps as may be desired.

page_text: Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what I
claim is:
1. In ceiling roses for electric lights and the like, providing in the base of the
rose (or in a projection on the base) a passage or channel of zig-zag form for the
reception of the wires or connections for supporting the lamp, substantially as
and for the purpose set forth.
2. In ceiling roses for electric lights, a projection or block such as d on the
base of the rose said block extending across that portion of the base on which
the terminal screws are fitted, substantially as and for the purpose set forth.
Dated this 3rd day of March 1899.
