A NEW CONSTRUCTION OF TROUGH OR OPEN TUBE, TO BE EMPLOYED FOR UNDERGROUND TRAMWAY CABLES
Year: 1884

page_text: I, CHARLES ALPHONSO ATKINSON, of Castle Street, Liverpool, Civil Engineer,
do hereby declare the nature of my invention for "A NEW CONSTRUCTION OF
TROUGH OR OPEN TUBE, TO BE EMPLOYED FOR UNDERGROUND TRAMWAY CABLES,"
to be as follows:-
This Invention is intended to be applied to Wire Cable Tramway Systems, the
object of my Invention being to provide a cheap and simple method of protecting
the underground cables used in the said Tramway systems.
Hitherto for such purposes the Troughs or subways have been formed in the
ground by means of continuous cast iron tubes or transverse iron frames with iron
plates or concrete between them, which has not only been expensive, but occupies
a long time to construct in consequence of the concrete requiring time to set and
harden.
My Invention is intended to provide simple and inexpensive means for
attaining the same object, and for this purpose I employ a trough or open tube,
made of earthenware or other suitably baked and burnt material. In the Cable
systems, there are placed at suitable distances apart in the ground, certain cast
iron frames for supporting the ironwork carrying the roadway and the pulleys
over which the cable runs, and between these cast iron frames I propose to place
the earthenware troughs which are made in convenient lengths and provided with
plain, socketed or rebated ends for the purpose of joining or coupling the troughs
together.
In order to prevent the upper edges of the troughs from being snipt and broken
by " Bets "
and other stones which cover the said troughs, I propose to place
packing on the upper edge of the troughs whereby such breakages are prevented.
By means of earthenware troughs constructed and applied according to my
Invention, considerable advantages are found over the systems at present in use,
as the earthenware troughs are brought to the place ready made, are easily handled
and quickly placed in position, whereas troughs made of concrete or iron are

longer time than is convenient for the public welfare, in addition to which the cost
much greater than earthenware troughs or open tubes.
The troughs possess the advantages over iron and concrete, of being imperishable
and of having a smooth glazed regular surface, easily cleansed, and not being
affected by moisture, can be laid during inclement weather and so avoiding danger
to the public by delay.

CABLES and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
This Invention is intended to be applied to Wire Cable Tramway systems, the
object of my Invention being to provide a cheap and simple method of protecting
the underground cables used in the said Tramway systems.
Hitherto for such purposes the troughs or subways have been formed in the ground
by means of continuous cast iron tubes or transverse iron frames with iron plates
or concrete between them which has not only been expensive but occupies a long
time to construct in consequence of the concrete requiring time to set and harden.
My Invention is intended to provide simple and inexpensive means for attaining
the same object, and for this purpose I employ a trough or open tube, made of
earthenware, or other suitably baked and burnt material, a cross section of which
is shewn at A in Fig 1 of the accompanying drawings and by side elevation in
Fig 2.
'
In the cable systems there are placed at suitable distances apart in the ground,
certain cast iron frames B for supporting the ironwork carrying the roadway as
well as the pullies over which the cable runs and between these cast iron frames B
I place the earthenware troughs A as shewn in the drawings and which are made
in convenient lengths and provided with plain, socketed, or rebated ends for the
purpose of joining or coupling the troughs together.
"
In order to prevent the upper edges of the troughs from being snipt and broken
by "setts or other stones which cover the said troughs packing may be placed
on the upper edge of the troughs whereby such breakages are prevented.
By means of earthenware troughs constructed and applied according to my
Invention, considerable advantages are found over the system at present in use as
the earthenware troughs are brought to the place ready made, are easily handled
and quickly placed in position, whereas troughs made of concrete or iron are
constructed or built upon the ground, consequently the streets are blocked up a
longer time than is convenient for the public welfare, in addition to which the cost
is much greater than earthenware troughs or open tubes.
The earthenware troughs herein mentioned possess the advantages over iron and
concrete of being imperishable and of having a smooth glazed regular surface,
easily cleansed and not being affected by moisture can be laid during inclement
weather and so avoiding danger by delay.

page_text: 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
In connection with underground cables, the use and employment of a trough or
tube made of earthenware or other suitably baked and burnt material, for purposes
substantially as herein shewn and described.
