PROVISIONAL SPECIFICATION.
Improved Means for Connecting the Branch Wires of an Electrio
Lamp to the Main Conductors, or for other similar purposes.
I HENRY SCHUSTER COwx of 19 Milton Street Hulme, Manchester, in the
County of Lancaster, Electrical Engineer, do hereby declare the nature of this
invention to be as follows:-
This invention relates to means for connecting the branch wires of an electrio
lamp to the main conductors of the installation, and for other similar purposes, the
principal object being to dispense with the use of soldered connections for this
purpose.
The invention consists chiefly of a rose or block of porcelain, or other suitable
material, which is so formed that the main conductors can pass through it, and,
whilst perfectly insulated from each other, can be set, in the rose or fitting itself,
in electrical connection with the respective terminals of the branch wires of the
lamp.
I make the rose by preference in the form of a circular block with a suitable
flange at its base and with two parallel grooves in its face, leaving a central
division or wall which is by preference bigher than the two outer walls of the
grooves.
In the bottom of each groove I fix a metal plate, and at each end of each
groove the flange is recessed, or the block is otherwise so formed as to allow
of the passage of one of the main conductors, which is connected to the plate at the
bottom of the groove by being looped round a screw, or by, a clip or other suitable
device.
A strip of metal forming part of the plate at the bottom of one of the grooves is
bent up against the inner wall and connected by a suitable fuse to the terminal of
one of the branch wires of the lamp. The metal plate in the other groove may be
in direct communication with the terminal of the other branch wire, this terminal
being preferably fixed on the outer wall of the groove.
I form curved or inclined holes leading from either side of the central wall to a
point near the centre of its width and the branch wires can thus be gripped so
as to support the lamp without any weight or strain upon the terminals.
I provide a cap or cover to this rose or block as usual, but I prefer to make this
cap with a loose ring or washer surrounding the inner part of the base of the
flange.
It will be seen that by the above appliance I am able to dispense with the
soldered connections of the branch wires to the main conductors, thereby saving
labour and materials.
Another important advantage obtained by this construction is that the central
division or wall separates and insulates the opposite poles which are thus contained
in independent chambers.
I would remark in conclusion that although I have described my invention as
applied to lamps it may be used for other similar purposes.
Dated this 9th day of March 1895.

COMPLETE SPECIFICATION.
Improved Means for Connecting the Branch Wires of an Electric.
Lamp to the Main Conductors, or for other similar purposes.
I HENRY SCHUSTER Cowx of 19 Milton Street, Hulme, Manchester, in the
· County of Lancaster, 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:-
This invention relates to means for connecting the branch wires of an electric
lamp to the main conductors of the installation, and for other similar purposes, the
principal object being to dispense with the use of soldered connections for this
purpose.
The invention consists chiefly of a rose or block of porcelain, or other suitable
material, which is so formed that the main conductors can pass through it, and
whilst perfectly insulated from each other, can be set, in the rose or fitting itself,
in electrical connection with the respective terminals of the branch wires of the
lamp.
The invention will be readily understood on reference to the accompanying
drawings of which
Fig. 1 is a sectional elevation of a rose made according to my invention and
Fig. 2 is a plan view thereof seen from beneath with the loose cover removed.
Figs. 3 and 4 are similar views of a modification thereof.
Figs. 5.and 6 are respectively side elevations and underneath plan of a further
modification with the loose cover removed.
. The same letters denote similar parts in all the illustrations.
I make the rose by preference in the form of a circular block a with a suitable
flange a¹ at its base and with two parallel grooves a³ in its face, leaving a central
division or wall a³ which is by preference higher than the two outer walls of the
grooves. These two outer walls a' may be dispensed with if preferred, as seen
atiFigs. 3, 4, 5 and 6, leaving the base at each side of the central wall a³ flat.
In the bottom of each groove or upon the flat part of the base of the block a
enveither side of the wall a', I fix a metal plate cand c', and at each end of each
groove the flange a' is recessed (see a+ Fig. 2) or the block a is otherwise so
formed (say with suitable holes a, see Fig. 4 or slots a see Fig. 6), as to allow of
the passage of one of the main conductors dor d' which is connected to one of
the plates cor c¹ by being looped round a screw e or el or by a clip or other
suitable device.
A strip of metal c+ forming part of the plate is bent up against the inner
wall a and connected by a suitable fuse to the terminal g₁ of the branch
wire or other conductor of the lamp. The metal plate c may be in direct com-
...munication with the terminal g of the other branch wire x or other conductor,
this terminal g being preferably fixed on the outer wall of the groove a² when
the block or rose is grooved (see Figs. 1 and 2) or it may be fixed on the wall a³
::as shewn.
I form curved or inclined holes leading from either side of the central wall a³ to
a point near the centre of its width see Figs. 1 and 2 or straight through
the wall a as seen at Figs. 3, 4, 5 and 6, and the branch wires xx¹ can thus be
gripped so as to support the lamp without any weight or strain upon the
terminals.
I provide a cap or cover to this rose or block a as usual.
It will be seen that by the above appliance I am able to dispense with the
soldered connections of the branch wires xxl to the main conductors d d¹ thereby
saving labour and materials.
Another important advantage obtained by this construction is that the central

page_text: division or wall a³ separates and insulates the opposite poles which are thus con--
tained in independent chambers. It will be evident that this rose may be applied
to brackets as well as to hanging lamps.
I would remark in conclusion that although I have described my invention as
applied to lamps it may be used for other similar purposes.
Having now particularly 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
A rose or fitting, for the purposes set forth above, provided with a suitable
cover and a division wall or partition, and so formed that the main conductors can
pass through it and, whilst insulated as perfectly as possible from each other can
be set in the rose or fitting itself in electrical connection with the respective
terminals of the branch conductors substantially as herein before set forth and
illustrated by the accompanying drawings.
