Improved Combination Electric Light Fittings.
I, WILLIAM SEVENOAKES, of Littlecot, Ashford, in the County of Middlesex,
Electrical Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improvements in and in connection with electric light
fittings, and has.for its objects, to provide economy of space in storing or carriage,
less damage in transit, the less need to maintain a large and varied stock, and
general convenience to electrical engineers.
In brackets, electroliers and such electrical fittings it has hitherto been custom-
ary to form the branch or branches integrally with, or screwed into the body,
while the lead wires had to be conducted through the said branches (after such
fixation) into the said body, whereat the two wires from each branch had to be
soldered or otherwise electrically connected to the positive and negative main
leads, and to alter, say a four light into an eight light electrolier, or a single
into a double or triple light bracket, has hitherto been next to impossible, or
would entail a great amount of labour.
My invention consists in providing in the body of a bracket, electrolier, or other
electric light fitting, at a point or points where a branch or branches would be
connected in the usual way, a hole or slot, while the heel of each of the said
branches would be so formed as to pass into either of the said slots or holes and
by an eighth of a turn, or more or less, imparted to the said branch it would
engage with the said body and be afterwards locked in connection therewith
The said branch or branches would each be provided with its own two necessary
wires before fixing, a pair of insulated plates being provided inside the said body,
and in electrical connection with the main leads, to which the wires of each branch
may be screwed and so form electrical connection between the said branch wires
and main wires. The heels of the said branches are so formed as to be adapted
for fixation to the said body so that the lighting end of the said branch may
point upwards or downwards, which provides that the said lighting end may be
arranged to carry a candle fitting, cord suspension or an oblique lamp.
By reason of the above mentioned easy means of mechanical and electrical con-
nection between the branches and the body it becomes an easy matter to connect
and disconnect the same, and which provides great facilities for packing and
transit, while the means for adapting any one branch for several uses affords a
great saving in the amount of stock required.

page_text: I, WILLIAM SEVENOAKES, of 13, Brownlow Street, Holborn, London, W.C.,
formerly of Littlecot, Ashford, in the County of Middlesex, 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 follow-
ing statement:-
My invention relates to improvements in, and in connection with electric light
fittings, and has for its objects to provide economy of space in storing, packing
or carriage, less damage in transit the less need to maintain a large and varied
stock, and general convenience to electrical engineers.
In brackets, electroliers and such electrical fittings it has hitherto been custom-
ary to form the branch or branches integrally with or screwed into the body
while the lead wires had to be conducted through the said branches (after such
fixation) into the said body, whereas the two wires from each branch had to be
soldered or otherwise electrically connected to the positive and negative main
leads and to alter say a four branch into an eight branch electrolier, or a single
into a double or triple branch bracket has hitherto been next to impossible, or
would entail a great amount of labour.
My invention consists in providing in the body whether globular or otherwise
of an electrolier or other electric light fitting at a point or points where a branch
or branches would be connected in the usual way a hole or slot, while the heel of
each of the said branches would be so formed as to pass into either of the said
slots or holes and by an eighth of a turn or more or less imparted to the said
branch it would engage with the said body and be afterwards locked in connection
therewith. The said branch or branches would each be provided with its own
two necessary wires before fixing, a pair of insulated plates being provided inside
the said body and in electrical connection with the main leads to which the wires
of each branch may be fixed by screws and so form electrical connection between
the said branch wires and main wires. The heels of the said branches are so
formed as to be adapted for fixation to the said body so that the lighting end of
the said branch may point upwards or downwards which provides that the said
lighting end may be arranged to carry a candle fitting, cord suspension or an
oblique lamp.
In order that my invention may be fully understood, I will more particularly
describe it making reference to the accompanying drawing, in which:
-:
Figure is a broken view in elevation of an electrolier embodying this in-
vention.
Figures 2 and 3 are broken views in plan and elevation respectively of one
of the branches.
Figure 4 is a broken view showing the arrangement of the branch to carry an
oblique lamp.
Figure 5 is a broken view showing the arrangement of the branch to carry a
candle fitting.
Figure is a view in plan of a body or centre part of the electrolier adapted to
carry two or four branches.
Figure 7 is a view in plan of a body or centrepiece adapted to carry 2, 4 or S
branches.
Figure 8 is a view in plan of a body piece for a wall bracket.
Figures 9 and 10 are views in sectional elevation and plan respectively-on an
enlarged scale showing one form the insulated plates may assume, and

page_text: Figures 11 and 12 are similar views on an enlarged scale showing another form
the insulated plates may assume.
Throughout the views similar parts are marked with like letters of reference.
My improved electrolier consists of a body piece A and of one or more branch
pieces B. The body piece A may be either adapted to be supported by suspension
as shown by Figure 1 or it may be formed as a wall bracket as shown by Figure 8.
The body piece may be adapted to receive any number of branches B. That
shown in Figures 1 and 6 is adapted to carry 2 or 4 branches. That shown in
Figure 7 to carry 2, 4 or 8 branches. That shown in Figure 8 one or three
branches. The branches B are adapted to be attached to the body piece A by
means of button, bayonet or similar joints as shown by Figures 1, 2 and 3, the
arrangement being such that they are securely attached to the body piece when
they are in a vertical position with the end adapted to receive or support the
lamp either way up. The ends of the branches are arranged to carry an oblique
lamp, a suspended lamp or a candle fitting.
In Figure 1 the end of the branch is shown with a fitment adapted to receive
a cord suspension. In Figure 4 the end of the branch is shown adapted to
receive an oblique lamp and Figure 5 shows a fitment 61 for adapting the end
of the branch to receive a candle fitting 2.
The button or bayonet holes a in the body piece A that are not required to
receive branches are closed by blank rose pieces as shown in Figures 6, 7 and 8.
To facilitate the connecting of the branch wire with the main wires, I employ
in each body piece a pair of metal plates C each enclosed in a box D) of any
suitable non-conducting material, as shown by Figures 9 and 10. The terminals
of the main wires are connected to the plates by the screw e and the terminals
of the branch wires by the screws there being as many screws as there are
branches B. It will be understood that all the positive wires are connected to one
of the plates C and all the negative wires to the other plate C.
Instead of using rectangular plates as shown in Figures 9 and 10, circular
plates may be employed in which case I prefer to mount them in one non-conduct-
ing block E as shown by Figures 11 and 12.
By reason of the above mentioned easy means of mechanical and electrical con-
nection between the branches and the body it becomes an easy matter to connect
and disconnect the same, and which provides great facilities for packing and
transit, while the means for adapting any one branch for several uses affords a
great saving in the amount of stock required.
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 electroliers and the like constructing the bodies or centre parts so that
any number of branches or their equivalents may be mounted on them, as and
for the purpose set forth.
(2) Constructing electroliers and the like by means of interchangeable parts,
as and for the purpose set forth.
(3) In electroliers and the like having detachable and interchangeable branches
or arms attaching the said branches or arms to the body or centre piece so that
they may be attached thereto either way up, as and for the purpose set forth.
(4) In electroliers and the like having detachable and interchangeable branches
or arms attaching the said branches or arms to the body or centre piece so that
they may be attached thereto either way up, and providing the ends of the
branches or arms with interchangeable pieces so that they may be used for either
oblique lamps, suspension lamps or candle fitments.
(5) For electroliers and the like the mechanical connecting up plates as herein-
before described and illustrated by Figures 9 and 10.
(6) For electroliers and the like. the mechanical connecting up plates as here-
inbefore described and illustrated by Figures 11 and 12.

interchangeable branches or arnis of mechanical connecting up plates, as and for
the purpose set forth.
