My Invention relates to conduits for electric mains and has for its objects
The laying of the conduits in such manner so as to avoid to a great extent the
breaking or opening up of the pavements or roadway when the mains are once laid
and thereby interfering with the traffic, and to facilitate the repairs to mains by
constructing the conduits in such a way that they may be easily opened and closed, at
the same time providing the conduits with suitable locks or fastenings to prevent their
being tampered with.
J. construct the conduit of cast iron stone earthenware or other suitable material
which may or may not be insulated by any suitable enamel or composition and it is
fitted with covers which can easily be removed.
The conduits may be placed underneath the pavement or they may be employed as
a kerb in place of the present stone kerb now generally used and can be made of
the necessary form and shape.

COMPLETE SPECIFICATION.
Improvements in Conduits for Electric Mains.
1, FLETCHER COATES of 65 Friday Street, in the City of London, 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:-
My invention relates to Conduits for Electric Mains and has for its objects
The laying of the Conduits in such manner so as to avoid to a great extent the
breaking into or opening up of the pavements or roadways when the Mains are once
laid and thereby interfering with the traffic and to facilitate the repairs to mains
by constructing the conduits in such a way that they may be easily opened and
closed at the same time providing them with suitable locks or fastenings to prevent
their being tampered with.
In order to carry out my invention in such manner as to avoid to a great
extent the breaking into or opening up of the pavements or roadways when the mains
are once laid I construct the conduits of cast iron, stone, earthenware, Portland
cement, or other suitable material which may or may not be insulated with any
suitable insulating material or composition and I provide the conduits with covers
which are so made that they can be easily removed without interfering with the
conduit itself.
I further construct my conduit in the form of the kerb now usually laid at the edge
of the footpath and it is so made that the conduit is employed not only as a receptacle
for Electric Mains but also for a kirb while to get at the Mains all that it is
necessary to do is to remove the cover. The cover is made with a rough surface to
prevent passengers from slipping.
I further provide for constructing my conduit in such a way that it can be laid
beneath the pavement on the inside of the kerb in such a manner that when it is
necessary to get at the mains only the first line of paving stones next to the kerb
and the cover of the conduit itself have to be removed.

page_text: Reference is made to the annexed drawings.
Fig. 1. is a section of the conduit in its position in the roadway as a kerb in which A
is the removeable cover B the stonepaving of footpath and the channel.
Fig. 2. is a section of the conduit in its position. behind the kerb A being the
removeable cover of conduit, B the paving stone, C the Channel and D the ordinary
stone kerb.
Fig. 3 is an end elevation of the conduit especially constructed for crossings.
Fig. 4 is a longitudinal section of the same."
The covers A are shown in Figs. 3 & 4.
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 :-
1st. The improvements in and connected with conduits for Electric Mains sub-
stantially as hereinbefore described.
2nd. The construction of the Conduit in such a manner that it can be used as a
kerb substantially as hereinbefore described.
3rd. The combination and arrangement of the conduit and kerb substantially as
herein before described.
