Complete Specification Left, 7th Feb., 1890-Accepted, 5th Apr., 1890
PROVISIONAL SPECIFICATION.
Improvements in Supporting Electric Conductors.
I, WILLIAM ARTHUR SMITH BENSON, of 2 Gordon Place, Campden Hill, in the
County of Middlesex, Architect, do hereby declare the nature of this invention to
be as follows:-
According to this invention I bind together the insulated conductors forming part
of an electric circuit or part thereof by a wire or wires wound spirally around them,
which wire gives an ornamental appearance to the conductors and lessens risk of the
conductors becoming injured. In order to take any longitudinal strain I lay wires
parallel to the conductors and within the spiral binding wire.
I attach the conductors to the electric lamp or to walls, ceilings or the like in the
following way-Upon the outside of the conductors I pass a tube, screw threaded on
the outside; this tube. is slotted to receive the longitudinal supporting wires and the
end of the protecting wire which are passed through inside it and turned backwards
in the slots, a cap or outer tube is then screwed on, whereby the longitudinal wires
and protecting wire are firmly held. This cap or outer tube has attached to it a
disc or bracket to be fixed to the wall, ceiling or other place from which it is desired
to suspend the conductors.
COMPLETE SPECIFICATION.
Improvements in Supporting Electric Conductors.
I, WILLIAM ARTHUR SMITH BENSON, of 2 Gordon Place, Campden Hill, in the
County of Middlesex, Architect; 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 :-
According to this invention I bind together the insulated conductors forming part
of an electric circuit or part thereof by a wire or wires wound spirally around them,
which wire gives an ornamental appearance to the conductors and lessens risk of the
conductors becoming injured. In order to take any longitudinal strain I lay wires
parallel to the conductors and within the spiral binding wire.
I attach the conductors to the electric lamp or to walls, ceilings or the like in
the following way-Upon the outside of the conductors I pass a tube, screw threaded
on the outside; this tube is slotted to receive the longitudinal supporting wires and
the end of the protecting wire which are passed through inside it and turned back-
wards in the slots, a cap or outer tube is then screwed on, whereby the longitudinal
wires and protecting wire are firmly beld. This cap or outer tube has attached to it
a disc or bracket to be fixed to the wall, ceiling or other place from which it is desired
to suspend the conductors.
Figure 1 of the drawing annexed shews a longitudinal section partly in elevation
of a support made according to my invention, the insulated conductors not being
shown.
A is the inner tube (shewn separately in elevation and end view at Figures 2 and 3)
having a screw thread B; it is cut away at C and notched or slotted at C³ to receive
the ends of the longitudinal supporting wires D and of the coiled wire E; these wires
are passed through inside it and turned backwards over the end. The cap F is
screwed on and holds the wires D D and E firmly. The drawing only shows one end
of the support suitable for being attached to a wall or ceiling the other end is

page_text: similarly constructed and carries the lamp. The wire E may either be tightly wound
round the conductors or the latter may fit loosely within the coil.
If preferred the slots C¹ might be cut through the whole length of the screw
threaded portion of the tube A. and the ends of the wires D and E be then nipped
between the end of the cap F and the shoulder on the tube A.
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
C
1. In a support for electric conductors the combination of a spirally wound wire
or wires enclosing the conductors with a longitudinal wire or wires for taking the
endway strain substantially as described.
2. In a support for electric conductors the combination of a spirally wound wire or
wires enclosing the conductors with a longitudinal wire or wires for taking the
endway strain the ends of these wires being held by an inner tube on which is
screwed an outer tube or cap substantially as described.
Dated this 30th day of January 1890.
