Improvements in the Mode of or Means for Supporting or Carrying
Telegraph or Telephone Wires or Lines.
I CHARLES MAYNARD of 20 Bucklersbury in the City of London Electrical
Engineer do hereby declare the nature of this Invention to be as follows :-
--
My Invention has for its object to so support or carry telegraph or telephone wires
or lines or leads that they are readily and conveniently erected and repaired and are
easily accessible and sufficiently protected.
According to my Invention I provide pipes troughs or containers of metal wood or
other suitable material in which the wires lines or leads are contained and supported
so that they are efficiently insulated. These pipes troughs or containers are affixed
to the walls copings or other suitable parts of the sides or roofs of buildings or other
structures in thoroughfares or other places by means of langers straps or other
convenient means. In crossing from one side of a street to the other or in like
situations they are brought up to the required elevation and carried across overhead
clear of traffic.
The system may also where circumstances require it have combined with it portions
which are carried underground for example where wide streets have to be crossed
the pipes troughs or containers may be carried downwards instead of upwards and
be led underground for the required distance and then be led up again to meet the
continuation of the pipes troughs or containers attached to the walls of buildings
or the like, at the other side of a street.
The tubes troughs or containers may be provided with readily removeable portions
to give access to the interiors.

I CHARLES MAYNARD of 20 Bucklersbury in the City of London 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 :-
My Invention has for its object to support or carry telegraph or telephone wires or
lines or leads so that they are readily and conveniently erected and repaired are easily
accessible and effectually protected and are much less liable to injury than is the case
with overhead wires or lines as hitherto arranged.
I will refer to the accompanying drawings in explaining my Invention but I wish
it to be understood that I do not limit myself to the precise details which I have
thercon illustrated.
According to my Invention I provide pipes troughs or containers of metal or of
wood or of other suitable material and of any suitable shape in cross section and
with plain or ornamental exteriors. In those pipes troughs or containers the telegraph
or telephone lines or wires are contained and they may be supported therein by any
suitable means such as by insulators on brackets or by filling in the space between
the interiors of the pipes troughs or containers with an insulating composition but I
preferably use supports which will allow the lines or wires to he readily accessible by
means of openings or doors which may be made at intervals in the pipes trouglis
or containers.
These pipes troughs or containers are affixed to the walls of houses or other
erections or to the copings thereof, or in, to, or upon, other suitable and accessible
parts of the roofs or sides of the buildings or structures in thoroughfares or other
places by means of hangers straps or other convenient means. Figure 1 of the
accompanying Drawing shews a section of the wall of a house with the trough A
fixed on the roof behind the coping, and extending by a connection A¹ to the roof
of a higher building.
In crossing from one side of the street to the other or in like situations the
troughs or the like A are brought up by branches therefrom to the required
elevation if they be not already at that elevation in their general line and
are carried across overhead clear of the traffic. This is illustrated by Figure 2 where
walls of houses on each side of a street are shewn and the trough A connects those A
on each side, being in communication with each. The system may also where
circumstances require it have combined with it portions which are carried under-
ground for example as shewn at A³ in dotted lines in Figure 2. The trough or the
like A on one side communicates with a branch A carried downwards and opening
into the cross part A³ extending for the required distance and then opening into
another branch A³ extending upwards and opening into the trough A on the other

side. This plan is applicable especially to the crossing of wide streets.
drawings the overhead part A2 is shewn as being supported by the coping and by
brackets B². When the underground crossing troughs or the like are used they may
be embedded in concrete or otherwise to ensure proper protection and insulation from
the earth. a are removeable portions or doors for gaining access to the lines or
wires in the troughs or the like.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what I
claim is :-
The mode of or means for supporting or carrying telegraph or telephone wires or
lines by means of pipes troughs or containers fixed to the sides or roofs or in on or to
other equivalent parts of buildings houses or structures in streets or the like
substantially as herein before described.
