An Improvement in or relating to Boxes for Electric Conduit Wiring.
I, CHARLES NEWTON RUSSELL, of 83 Claremont Road, Highgate County of
Middlesex, Electrical Engineer, do hereby declare the nature of this invention
to be as follows:
This invention relates to an improvement in Boxes for Electric conduit wiring.
For the purpose of my invention, I make my boxes of straight, curved, bent,
angle, or other form with an oblong or other opening at one portion preferably
on a flat, and provide said opening with a lipped cover to sit upon and partly
within the edge of the box in and on which it can be located and luted and be
fastened by removable lip plates which can be swung round or otherwise shifted
upon screw pins which otherwise fix the plates and the lid firmly in position.
The ends of the boxes are sorew threaded for the connection of the wire
conduit pipes.

An Improvement in or relating to Boxes for Electric Conduit Wiring.
I, CHARLES NEWTON RUSSELL, of 83 Claremont Road, Highgate, 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 following statement:-
This invention relates to an improvement in Boxes for Electric conduit wiring.
For the purpose of my invention I make my boxes of straight, curved, bent,
angle, or other form with an oblong or other opening at one portion preferably
on a flat, and provide said opening with a lipped cover to sit upon and partly
within the edge of the box in and on which it can be located and luted and be
fastened by removable lip plates which can be swung round or otherwise shifted
upon screw pins which otherwise fix the plates and the lid firmly in position.
The ends of the boxes are screw threaded for the connection of the wire
conduit pipes.
The drawings annexed hereto will explain my invention, said drawings showing
a corner box for electric conduit wiring from say two right angled walls such

page_text: as those of a room but the boxes can be formed to suit any angles whether it
be for a straight line of wiring or upwardly or in other direction.
Figure 1 is a view of a box of my invention with the cover plate removed,
said cover plate being shown inverted at Figure 2 for exposing the base which
falls within the top edge of the box opening.
Figure 3 is an elevation or a plan of the corner box with the cover plate or
lid in position and locked by the clip swing plates and the screws which also
serve as pivot pins for the awing plates to turn on.
A is a conduit wiring corner box of trough formation and having the ends B, B,
partially closed and internally screw threaded for the reception of screw ended
pipes C, C, the inner ends of which coincide with the bottom of the trough so
that the wires when laid therein rest upon the same level.
D is the cover plate which can he dropped on to the top or front edge of the
trough A after being luted with a mastic or cement or a thin lead luting and
then by turning the swing plates E, E, on their pins F, F, from the position
shown at Figure 1 to that represented at Figure 3 the cover plate or lid D when
placed on is held firmly, the shoulder or base G being within the trough A and
the lip H on the edge I.
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 construction of boxes for Electric conduit wiring, each box being com-
posed of a trough A with screw threaded ends B, B, cover plate D and swing
clip plates E, E, all arranged substantially as shown, and as and for the purposes
desoribed.
2. The hereinbefore described improvement in or relating to boxes for electric
conduit wiring as represented on the annexed drawings.
