PROVISIONAL SPECIFICATION.
Improvements in means for Connecting or Continuing Electric Cir-
cuits through Electroliers, Brackets for Electric Lamps, and the
like.
I, JOSEP BERNARD CLARKE of 22 Dudley Street Wolverhampton, Electrical
Engineer, do hereby declare the nature of this invention to be as follows:
―
My invention relates to improved means where by the wires arranged for con-
veying, an electric current or currents, through electroliers, brackets and the like,
to electric lamp or lamp's are connected to the lead wires by means of safety fuses,
after the electrolier or other fitting is fixed in position.
The following is a convenient arrangement according to my invention:--
I provide at the part of the ceiling, or wall, or other place of support, to which
the electrolier or the like is to be attached, a ceiling plate, or back plate, with a
screwed socket provided in its centre, to support the electrolier or other fitting.
To this ceiling plate or back plate, is affixed an insulating piece of porcelain or
other suitable material, provided with metal terminals, into which, I permanently
connect the lead wires.
On the stem or arm of the electrolier or other fitting is affixed another
insulating piece, also, provided with metal terminals, into which I connect
the wires to and from the electric lamp or lamps, thereby permanently wiring the
electrolier or other fitting, before being fixed to its support, thus avoiding the
troublesome method of jointing, and no disturbance of the wires takes place in
taking down & refixing.
I provide on the end of the stem, or arm, of the electrolier, or other fitting, a
screw.
To fix the electrolier or other fitting, I screw the screwed end of the stem, or
arm of the electrolier or other fitting, into the screwed socket, on the ceiling plate
or back plate.
I arrange the terminals on the stem or arm porcelain piece to come into a posi-
tion similar to the terminals on the ceiling plate porcelain piece.
Thea by means of safty fuses fastened under the heads of screws, I connect the
lead wire terminals to the lamp or lamps wire terminals, thereby establishing
continuity of circuit.

I, JOSEPH BERNARD CLARKE of 22 Dudley Street, Wolverhampton, 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 improved means where by the wires arranged for con-
veying electric current or currents through electroliers, brackets ando the like
to electric lamps or lamp are connected to the lead wires by means of safty fuses,
after the electrolier or other fitting is fixed in position.
According to my invention I provide at a part of the ceiling or wall or other
place of support, to which the electrolier or the like is to be attached, a ceiling
plate or back plate with a screwed socket provided in its centre, into which the
stem or arm of the electrolier or the like is screwed.
To this ceiling plate or back plate is affixed an insulating piece of porcelain or
other suitable material provided with metal terminals to which I permanently
connect the lead wires. On the stem or arm of the electrolier or the like is affixed
another insulating piece of porcelain or of other suitable material also provided
with metal terminals, to which, I connect the wires to and from the electric lamp
or lamps thereby permanently wiring the electrolier or the like before being
secured to the ceiling, wall or the like attachment.
The mechanical connection is made by screwing the stem or arm of the electro-
lier or the like into the screwed socket of the ceiling, wall or the like attachment.
The electrical connection is effected by means of safty fuses, inserted between the
lead wire terminals and the lamp or lamps wire terminals, after the electrolier or
the like is screwed in position.
The following is a convenient arrangement according to my invention which
I will describe with reference to the accompanying drawings.
Figure 1, being a vertical section of the attachment for the ceiling, wall or the
like.
Figure 2 a vertical section of the attachment for the stem or arm of the electro-
lier or the like, shewing intermediate socket, which can be unscrewed from the
stem or arm to facilitate wiring.
Figure a view of the stem or arm of the electrolier or the like shewing
screwed end.
Figure 4 a plan of the stem or arm shewing wires extended from inside.
Figure 5 an inverted plan of the attachment for the stem or arm of the electro-
lier or the like, shewing terminals.
Figure 6 a view of the parts secured together with fuse in place.
Figure 7 an inverted plan of the ceiling, wall or the like attachment, shewing
the terminals to which the lead wires are attached.
On the ceiling, wall or other place to which the electrolier or the like is to be
attached, I fix a ceiling plate or back-plate A with a screwed socket provided in
its centre. This said plate A, carries an insulating piece B, of porcelain or other
suitable material provided with metal terminals CC, to which I permanently con-
nect the lead wires F F, thus terminating the lead wires in the ceiling attach-
ment independantly of the other part of the fitting.
At the end of the stem or arm E, I make slots or holes K K, through which I
extend the lamp or lamps wires F2 F³.

page_text: I provide on the end of the stem or arm E of the electrolier or the like, a screw
thread, over which I screw an intermediate socket A2, having a nipple at one end,
over this socket I secure an insulating piece B, provided with metal
terminals C³ C³. I extend the lamp or lamps wires F2 F2, through the slots K K,
in the stem or arm of the electrolier or the like, then I screw the intermediate
socket A³ on to the screwed end of the stem or arm E, after which I prepare the
wires F F³, and arrange them to receive the terminals CC, which being
secured to the insulating piece B are put over or in close proximity to the ends of
the wires simultaneously as the aforesaid insulating piece 133 is put into position
on the socket A2, the wires are secured to the terminals by means of screws, thereby
permanently wiring the electrolier or other fitting, before being screwed to the
supporting attachment A.
To attach the electrolier or the like to its supporting attachment A on the
ceiling, wall or other place, I screw the nipple of the intermediate socket A into
the screwed socket A.
Dis a washer of suitable thickness to arrest the electrolier or the like in any
desired position, convenient to insert fuses connecting the terminals Cª C³, with CC.
I insert safty fuse L (one only is shewn) between the lead wire terminals C C,
and the lamp or lamps wire terminals C C³, the fuses are secured by the
screws JJ, and J2 J2, in the terminal plates H H and H2 H3 which support the
terminals C C and C³ C³, there by establishing continuity of circuit, thus avoiding
the troublesome method of jointing and making the electrolier or the like, easily
detachable and no disturbance of the wires takes place in taking down and
refixing also the arrangement is specially adapted to high voltage circuits.
M. is a movable cover which is screwed into place after the fuses are inserted.
Terminals for more than one circuit can be arranged on the aforesaid insulating
pieces B and Bª.
I do not limit my self to the precise form shewn.
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. Terminating the lead wires in terminals or contact pieces on a rose or block
of insulating material, having in the centre provision for supporting the electro-
lier, bracket, or the like which after having the lamps or lamp wires terminating
in terminals or contact pieces arranged on insulating material secured to the stem
or arm of the electrolier, or the like, is screwed to the ceiling attachment in such
a position that by means of safty fuses, or connectors the circuit is completed
substantially as hereinbefore explained.
2. The termination of the lead wires, and the lamps or lamp wires in termina-
tions independant of each other, connected by means of safty fuses, after the
electrolier or the like is screwed in position according to the arrangement and
combination of parts substantially as hereinbefore described and illustrated
in the accompanying drawings.
