Improvements in Ceiling Roses and Wall Plugs for Electrical
Fittings.
I WALTER POYNTER ADAMS of "Springwell" Barnes, in the County of Surrey,
Electrical Engineer, do hereby declare the nature of this invention to be as
follows a :-
The object of my invention is to facilitate the attachment and removal of the
fitting suspended from the ceiling rose. One way in which this object is attained
is illustrated in the accompanying drawing and described below.
The ends of the suspending wires are connected to metal contact pieces fixed to a
piece of porcelain or other suitable material independent of the base and cover.
This separate piece is shewn in Fig. 1 with the metal contact pieces B, B. fixed
at each end, and may be of any suitable shape and may be solid or pierced with
holes for threading the ends of the flexible wire through. In the figure it. is shewn
solid and before fixing the ends of the wires under the screws in the contact
pieces B. one or two turns would be taken round the bar.
The base of the rose is shewn in the other three figures giving plan, elevation,
and side views. The leading in wires are fixed to the metal pieces A, A, under
which the bar is pushed so that B, B. come into intimate metallic contact
with A, A.
A fuse, not shown in the drawings, of any approved design may be attached
either to the base or to the bar.
A cover, not illustrated, is screwed over the whole, and through a hole in the
centre of this the flexible wire. passes.
Modifications in the apparatus as described may be made as necessary, but the
principle of my invention is the fixing of the flexible wire to a piece of porcelain or
other suitable material independent of either cover or base.
Another form in which the piece may be made is that of a plug, with suitable
connections passing through the centre of the cover and provided with a means of
firmly fixing it to the rose so that it cannot be pulled out by any weight attached
to the wire.
.
In this form the apparatus may be used as a wall: plug for flexible wire and has
the advantage of those in general use in that the plug cannot be pulled out of the
socket.

COMPLETE SPECIFICATION.
Improvements in Ceiling Roses and Wall Plugs for Electrical
Fittings.
IWALTER POYNTER ADAMS of Springwell, The Terrace Barnes, in the County
of Surrey, 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 :-
The object of my invention is to facilitate the attachment and removal of the
fitting suspended from the ceiling rose.
One way in which this object is attained is illustrated in the drawings left with
the Provisional Specification and is described below.
The ends of the suspending wires are connected to metal contact pieces fixed to
[Price Bd.]

page_text: a piece of porcelain, vulcanised fibre, or other suitable material independent of the
base and cover.
This separate piece is shown in Fig. 1, with the metal contact pieces B. B. fixed
at each end, and may be of any suitable shape and may be solid or pierced with
holes for threading the ends of the flexible wire through. In the figure it is shewn
solid, and before fixing the ends of the wires under the screws on the contact
pieces B one or two turns would be taken 'round the bar.
The base of the rose is shewn in the other three figures giving plan, elevation and
side views. The leading in wires are fixed to the metal pieces A. A. under which
the bar is pushed so that B. B. come into intimate metallic contact with A. A.
A fuse, not shewn in the drawings, of any approved design may be attached either
to the base or to the bar.
A cover not illustrated is screwed over the whole and through a hole in the
centre of this the flexible wire passes.
Another form of the apparatus may be made by using a plug with suitable con-
nections passing through the centre of the cover. The plug being so arranged that
when in place it is firmly fixed.
In this form the apparatus may be used as a wall plug for flexible wire and has
the advantage of those in general use in that the plug cannot be pulled out of the
socket.
An illustration of this is given in Fig. 2 where A. represents the plug having
connections B. & C. The flexible wires pass through the hole D and one is fixed
under screw C and the other is soldered or otherwise connected to B.
The plug passes through the cover E. the flanged portions of B. pass between
plates F. & H. and when thrust home a quarter turn is given to the plug and on
releasing pressure B. rests on F. & H. making contact with F. which is connected
by a fuse wire to plate K.
C. makes contact with L. which is made of strong spring metal.
M & N are holes through the porcelain base for the leading in wires.
Modifications in the apparatus as described may be made as necessary.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
(1.) The adoption of an extra part in ceiling roses in addition to the base &
cover, and independent of both for fixing the flexible wires to, in a manner sub-
stantially as described.
(2.) The means of securing contact and fixing the extra part substantially as
described.
(3.) The application to wall plugs of the method adopted in this invention for
fixing the extra part-or plug-so that pulling the flexible wires will not pull out
the plug.
Dated this 1st day of September 1892.
