PROVISIONAL SPECIFICATION.
Improved Ceiling Rose or Connector for Electrical Circuits and for
the Suspension of Electrical Fittings.
EDWARD WILLIAM LANCASTER of Albert Works Graham Street Birmingham
Electrical Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention consists of an improved Ceiling Rose or Connector of suitable
insulating material for suspending and connecting electric light pendants or electroliers.
I make a base of suitable size and of china, slate hardwood or other suitable insulating
material having a projecting piece from the centre which is provided with two or
more holes for passing the electric leads or wires from the pendant to the metallic
terminals which I place on the flat part of the base for connecting these pendant
wires to the supply leads or wires. The base is then provided with a cap which covers
the terminals & connections. In order to clearly describe my invention, I attach
drawings illustrating a form of my improved Ceiling Rose. Similiar letters indicate
similiar parts in all figures.
Fig. 1. represents plan view of the base.'
Fig. 2. represents an elevation of base with projecting piece & cover B. is the said
base of suitable insulating material with the piece C. attached having the holes H for
passing the wires from the electric light pendant or electrolier. I is the metallic
terminal for the said wires.
E is the cover which may screw on the base B as shewn in drawing, or may have
a nut & washer at K to screw on the projecting piece to hold the cover in position.
At the point D 1 provide a centro hole to allow a metal bolt to pass through which
may support a heavy electrolier from a plate that may be fixed to the ceiling and so
relieve the Ceiling Rose of the whole weight of the fitting.

COMPLETE SPECIFICATION.
Improved Ceiling Rose or Connector for Electrical Circuits and for
the Suspension of Electrical Fittings.
I, EDWARD WILLIAM LANCASTER Albert Works Birmingham 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:
My invention consists of an Improved Ceiling Rose or Connector of suitable
insulating material for suspending electric light pendants or electroliers. I make a
base of suitable size and shape of china slate hardwood or other suitable insulating
material having a projecting piece from the centre which is provided with 2 or more
holes for passing the electric leads or wires from the pendant to the metallic terminals
which I place either on the flat part of the base or on the projecting piece or other-
wise as may be most suitable for connecting the pendant wires to the supply leads or
wires. The base or projecting piece is then provided with a cap which covers the
terminals and connections. In order to clearly describe my invention I attach
drawings illustrating a form of my improved Ceiling Rose Connectors. Similar letters
indicate similar parts in all figures.
Fig. 1 represents plan view of the base.
Figs. 2, 3, and 4 represent elevations of base with projection piece and covers. B. is
the said base of suitable insulating material with the piece C. attached having the

page_text: holes or grooves H for passing the wires from the electric light pendant or electrolier.
1 is the metallic terminal for connecting the said wires. E is the cover which may
screw on the base B. as shewn in drawing, or may have a nut or screwed cap to screw
on the projecting piece K. to hold the cover in position which may or may not be
screwed on to the base. At the point D. I provide a centre hole to allow a metal
bolt or tube to pass through which may support a heavy electrolier from a plate that
may be fixed to the ceiling joist or other suitable place and so relieve the Ceiling
Rose of the whole weight of the fitting.
The base and cover with projecting piece may be made of any shape to suit
decoration or otherwise and the connections may be arranged for any special require-
ment, as in Fig. 4 where it represents the use as lamp holder connector. The hole D.
may be utilized for a gas supply pipe for supplying gas and electric light fitting.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed, 1 declare that what 1
claim is:
1. A base of insulating material having a projecting piece fixed thereto and pro-
vided with a method of fixing the cover to the base or projecting piece substantially
as described and illustrated.
2. A ceiling Rose or connector of insulating material for electrical circuits having
a projecting piece for passing the wires from an electrolier and pendant through the
projecting piece (irrespective of the cover) in such a manner as to protect and
insulate the wires from each other substantially as described and illustrated.
3. A Ceiling Rose or Connector of insulated material having a projecting piece
through which the wires from a pendant or electrolier may pass to connecting piece
and having a pin bolt or pipe passing through the centre for supporting the weight
of a pendant or electrolier substantially as described and illustrated.
Dated this 4th day of January 1890.
