PROVISIONAL SPECIFICATION.
Improvements in or appertaining to Casings for Electric Light and
similar Cables.
We, ARTHUR HUDSON, of 5, Cheapside, in the City of Bradford, Electrical
Engineer, and CHARLES JOHN WIGHTMAN, of 60, Harris Street, Bradford, afore-
said, Timber Merchant, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in or appertaining to casings or con-
duits for electric cables for lighting and similar purposes, and its object is to
provide a serviceable, compact and fire proof casing.
To carry out our invention we enclose the wood or other insulating case in a
light metal sheath or shell made in suitable lengths or sections and split prefer-
ably along both sides or edges. The split sides may more or less overlap each
other in which case the sides of the upper or inner half preferably pass between
those of the lower or outer half. The sections may be secured in position by
suitable metal or other clips or fasteners which may be placed over the junctions
of the sections.
The junction boxes are made of short sections with suitable holes or notches
cut out at the sides to permit the wires or cables to pass through.
The metal sheath efficiently protects the casing from external injury so that
it may with advantage be made lighter or smaller in cross section.

Improvements in or appertaining to Casings for Electric Light and¨
similar Cables.
We, ARTHUR HUDSON, of 23, Piccadilly, Bradford, in the County of York,
Electrical Engineer, and late of 5, Cheapside, Bradford, aforesaid, and CHARLES
JOHN WIGHTMAN, of 60, Harris Street, Bradford, aforesaid, Timber Merchant,
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 improvements in or appertaining to casings or con-
duits for electric cables for lighting and similar purposes, and its object is to
provide a serviceable compact and fire proof casing.
To carry out our invention we enclose the wood or other insulating case in a

page_text: light metal sheath or shell made in suitable lengths or sections and split pre-
ferably along both sides or edges. The split sides may more or less overlap each
other in which case the sides of the upper or inner half preferably pass between
those of the lower or outer half,
To fully describe our invention, reference is made to the accompanying sheet
of drawings, forming a part of this specification, in which similar figures of
reference indicate corresponding parts in each of the views...
Figure 1, represents a perspective view of a junction box having four branches.
The lid of the junction box is omitted.
Figure 2, is an elevation of a wall junction box without the lid. In the case
of a ceiling box this view represents the underside when fixed.
Figure 3, is a side view of the same.
Figure 4, is a side view of a portion of the casing with parts broken away to
show the parts beneath.
Figure 5, is a front view and Figure 6, is a cross section of the same.
The wooden or insulating case 1 having a lid 2 of insulating material is placed
within the sheet metal sheath 3 and is enclosed by the outer sheath 4. The case
and shells are made in sections of convenient length and the sections are simply
placed end to end as shown at 6 Figures 4 and 5 care being taken to have the
joints in the sheaths 3 and 4 a considerable distance away from each other and
the joints in the sheath 4 may be concealed by one of the metal straps 8 ém-
ployed to secure the casing to the wall or ceiling.
The junction boxes 9 are made with openings 10 in the sides for the ends of
the casing carrying the main cable and with any number of openings 12 for the
casing carrying the branch cables. The boxes are connected by screws 14 to the
wall or ceiling and form a support for the ends of the casings passing into them.
-
Having now particularly described and ascertained the nature of our said in-
vention, and in what maner the same is to be performed, we declare that what
we claim is-
1. The combination with an inner casing of wood or other insulating material
of a split metal outer sheath, substantially as herein shown and described:
2. The combination with an inner casing of wood or other insulating material
of a split metal outer sheath and junction boxes formed and arranged substantially
as herein shown and described.
