PROVISIONAL SPECIFICATION.
Improved Junction or Fuse Box for Electric Wires.
I, CHARLES NEWTON RUSSELL, of The London and Lancashire Electric and
General Engineering Company, Limited, of Kingsland Green, Dalston, London,
Manager, do hereby declare the nature of this invention to be as follows:-
This invention relates to junction or fuse boxes for electric wires, the object
being to provide them with porcelain or other non-conducting fittings for the
connection, perfect insulation, and distribution of electric wires from the main
cable to the lamps, or other position where a supply of current may be required;
also to construct such junction boxes that water cannot penetrate through the
joint between the cover and the shell of the box.
The junction box is formed with the usual socket connections for the pipes
containing the main cable aud lamp wires respectively, and within the box is a
porcelain or other bed serving as an insulating body between the back of the
box and the main cable and is grooved for its reception. Another insulating
piece or disc fits over the first piece, the main cable being between the two, and
the lamp or other wires are led through holes in the second porcelain piece to
the fuse arranged between terminals on its front, from whence they are led
through the branch sockets to the lamps, the porcelain edges being chamfered
to allow the free ends of the wires to enter the branch sockets.
The box is closable by an internal or external fitting lid or cover placed over
a central stud or pin which passes through holes in the two porcelain insulators.
and is fixed in the box, the lid after being luted with red lead, or other seal is
secured by a single nut screwed upon the stud or pin.
By this invention, the danger of short circuiting is reduced owing to the
interposition of the porcelain insulator between the main and branch wires, and
an even circumferential pressure on the lid or cover is obtained by the single
centrally arranged pin and nut.

I, CHARLES NEWTON RUSSELL, of The London and Lancashire Electric and
General Engineering Company, Limited, Manager, 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 junction or fuse boxes for electric wires, the object
being to provide them with porcelain, or other non-conducting fittings for the
connection, perfect insulation, and distribution of electric wires from the main
cable to the lamps or other position where a supply of current may be required;

between the cover and the shell of the box.
My invention will be clearly understood by the aid of the annexed drawings.
Figure 1 section. Figure 2 plan. Figures 3 and 4 details.
The junction box A is formed with the usual socket connections B, B, for the
pipes C, C, containing the main cable D and lamp wires E respectively. Within
the box A is a porcelain or other bed F serving as an insulating body between the
back of the box and the main cable which is grooved for its reception. Another
insulating piece or disc G fits over the first piece F, the main cable being between
the two. The lamp or other wires are led through slots or holes in the second
porcelain piece to the fuse H arranged between terminals on its front, from whence
they are led through the branch sockets to the lamps J, J, the porcelain. edges
being chamfered to allow the free ends of the wires from the pipes to enter the
branch sockets.
The box is closable by an internal or external fitting lid or cover K placed over
a central stud or pin L which passes through holes in the two porcelain insulators
and is fixed in the box, the lid after being luted with red lead or other seal is
secured by a single nut on the stud or pin.
The subsidiary wires are arranged in a modified form of box having a porcelain
disc within it for the connection of the lamp wires, the modified form of box
serving also as a ceiling rose as shown.
By this invention, the danger of short circuiting is reduced owing to the
interposition of the porcelain insulator between the main and branch wires, and an
even circumferential pressure on the lid or cover is obtained by the single centrally
arranged pin and nut.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed I declare that what
I claim is -
1. The improvement in socketed junction or fuse boxes for holding electric main
wires and branch or lighting wires insulated from each other in and by the means
described and substantially as shown.
2. In a junction and fuse box of the kind described and shown, the employment
of two channeled or grooved insulator discs for reception of main wires and
connection of branch or lighting wires, as set forth.
