PROVISIONAL SPECIFICATION.
An Improved Means of Wiring Brackets, Pendants, Electroliers, and
the like for Electric Lighting.
1, 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 relates to an improved means whereby the wires arranged for
conveying an electric current through a bracket, pendant, or other fitting to an
electric lamp, may be permanently wired to an insulated connectors at the back of
the plate, ceiling plate, or body of the fitting and to which may be connected the
branch or leading in wires, when the fitting is to be fixed, and the connections made
by means of screws when the fitting is almost in position so that the fixing or taking
down of the fitting is made as simple and efficient as possible and that no disturbance
of the wires takes place; thus the time spent in making joints is saved, and the
risk of short circuits avoided. To secure this end, I cast or solder inside the cup
shaped back plate, ceiling plate or body of the fitting two metallic projecting pieces
or lugs to which I screw an insulating piece of porcelain or other suitable material.
To one side of this insulating piece I attach a terminal piece and to the other side
a similar terminal piece.
Each terminal contains two or more cable holes and binding screws, and to one
terminal I connect the positive wires from the lamp or lamps and circuit respectively,
and to the other terminal the corresponding negative wires. In making the connec-
tions I first join the lamp wires to their respective terminals and then placing the
bracket as nearly as possible in position connect up the circuit wires.
I make the terminals of such a shape as to facilitate this operation as much as
possible.

I, EDWARD WILLIAM LANCASTER, of Albert Works, Graham Street,
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 relates to an improved means whereby the wires arranged for
conveying an electric current through a bracket pendant or other fitting to an
electric lamp; may be permanently wired to insulated connectors in the back plate
ceiling plate, or body of the fitting & to which may be connected the branch or
leading in wires when the fitting to be fixed is almost in position, so that the fixing
or taking down of the fitting is made as simple and efficient as possible and that no
disturbance of the wires takes place. Thus the time spent in making joints is saved
and the risk of short circuits avoided. To secure this end I cast or fix inside the
back plate ceiling plate or body of the fitting two metallic projecting pieces or lugs,
or I provide a specially shaped piece of metal, to which
insulating pieces of porcelain or other suitable material. To the insulating piece
or pieces I attach a metal terminal piece or pieces. Each terminal contains two or
more cable holes & binding screws, and to the metal terminal, I attach one of the
screw one or more

page_text: wires from the lamp & circuit respectively, and to another similar terminal piece
the corresponding negative or return wires. In making the connections, I first joint
the lamp wires to their respective terminals, and then placing the bracket in position
as nearly as possible, connect up the circuit wires. I make the terminal of such a
shape as to facilitate this operation as much as possible.
:
The casting or back piece & terminal may be covered by a rose or cover of
suitable shape, and which may be made to be fixed into position by means of a
milled nut screwed up to it or by means of a screw or screws fixing it to the tube
back plate or block, or the rose or cover may be made in two or more pieces and so
made as to fit together & form a suitable covering for the connecting pieces.
By my invention brackets, pendants electroliers, standards, and similar fittings
may be easily & efficiently fixed and removed without the necessity of jointing of
wires in the ordinary way and the insulated pieces may be arranged to have a
connection for a fusible cutout.
I attach drawings illustrating examples only of the application of my said inven-
tion, and the manner the same is carried into effect.
In all the figures similar parts are similarly lettered.
Figs. 1, 2, 3 & 4, shew the application to a pendant, where A is the back or
ceiling plate, A¹ the pendant body, B B the insulating pieces screwed to A. & A'
respectively upon the lugs L L by means of the screws S S and C the movable
cover or ceiling rose D D the terminal pieces with their binding screws E E,
FF the circuit wires & G G the lamp wires. S₁ S₁ are the screws by which the
terminals are attached to the insulating pieces T the pendant tube.
Figs. 5 & 6 represent the back plate of a bracket, but the arrangement shewn in
Figs. 1 & 2 where a movable cover is employed may also be applied to brackets.
Figs. 7, 8, & 9 shew the arrangement applicable to either bracket or pendant of
a movable cover in two parts one of the terminal pieces is so arranged as to permit
the introduction of a fusible cutout.
Having now fully described and ascertained the nature of my said invention and
in what manner the same is to be performed I declare that what I claim is :-
1. The combination of an insulated piece or pieces fixed to the back plates or
body of a pendant or electrolier having metallic terminal pieces for easily attaching
the wires or cables from the lamps and the wires and cables from the supply mains
substantially as herein described and illustrated.
2. The combination of insulated piece or pieces fixed to back plates or brackets
pendants or electroliers and a movable cover or rose in one or more pieces, covering
same & easily removable for facilitating the connecting or disconnecting of the
electric wires.
