PROVISIONAL SPECIFICATION.
Improvements in Conduits for Gas Pipes, Electric Wires or Cables,
and other analogous purposes.
I, WILLIAM SAYER of 150 Uttoxeter New Road, Derby in the County of Derby,
Engineer, do hereby declare the nature of this invention to be as follows:-
The object of my invention is to provide a simple form of section for use in forming
conduits for the reception of electric wires or cables, leaden gas or water mains and
similar purposes; such sections being formed so that they are reversible either end
for end or for forming the top or bottom of the conduit; it will be evident that a
conduit composed of sections which are practically all alike will be very easily and
expeditiously laid and re-laid.
In carrying out my invention I form sections in clay, earthenware, or other
suitable substance or composition each of which is provided with a flat bed and a
longitudinal hollow on the top surface sufficiently wide and deep to receive the wires,
lead pipes or the like; the top face is also formed with a longitudinal rib on one side
of the central hollow and a corresponding longitudinal groove on the other side. The
foregoing description applies to a section when used as the lower half of a conduit it
will be understood however that when used to form the upper half or portion the
longitudinal rib of one fits into the longitudinal groove of the other, each section
being thus reversible and interchangeable. The rib and groove keep the upper half
in position, cement being used or not as required in most cases however it will not be
required as this invention is designed partly to afford a ready means of access to the
wires, pipes or the like without having to break the parts of the conduit.
Suitable junctions will be provided where required for connection with the main
pipes or wires inside the conduit, such junctions merely consisting of an orifice formed
in the side of the top and bottom sections of the same or a different sectional area as
the main conduit.
The sections may be formed in or by any suitable machine apparatus or method.

I, WILLIAM SAYER of 150 Uttoxeter New Road, Derby in the County of Derby,
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 :-
The obiect of my invention is to provide a simple form of section for use in forming

page_text: puron or electric wires or cables, gas or water mains and similar
purposes, such sections being formed so that they are reversible either end for end or
for forming the top or bottom of the conduit; it will be evident that a conduit
composed of sections which are practically all alike will be very easily and
expiditiously laid and re-laid.
In describing my invention reference will be had to the different figures upon the
accompanying sheet of drawings.
Figure 1 is perspective view shewing the application of my invention as will be
hereinafter explained.
Figures 2 and 3 are also perspective views shewing different forms of my
invention.
In carrying out my invention I form sections A in clay, earthenware, or other
suitable substance or composition each of which is provided with a flat bed and a
longitudinal hollow B on the top surface sufficiently wide and deep to receive the
wires, lead pipes or the like; the top surface is also formed with a longitudinal rib C
on one side of the central hollow and a corresponding longitudinal groove D on the
other side. The foregoing description applies to a section when used as the lower
haif of a conduit it will be understood however that when used to form the upper half
or portion the longitudinal rib of one fits into the longitudinal groove of the other,
each section being thus reversible and interchangeable. The rib and groove keep the
upper half in position, cement being used or not as required, in most cases however
it will not be required, as this invention is designed partly to afford a ready means
of access to the wires, pipes or the like without having to break the parts of the
conduit.
Suitable junctions will be provided as shewn upon Figure 1 where required for
connection with the main pipes or wires inside the conduit, such junctions merely
consisting of an orifice E formed in the side of the top and bottom sections of the
same or a different sectional area as the main conduit.
Upon Figure 2 an adaptation of my invention is shewn for providing a double
conduit one over the other, the top and bottom sections A1, A2, being interchangeable
while the central portion F is made with the top and bottom surfaces alike. In
Figure 3 another form of my invention is illustrated also providing a double conduit
the passages B', B2, in this case running side by side the top and bottom sections A³, A',
being interchangeable as before.
It will be readily understood that without departing from the spirit of my invention
I may provide any number of open passages running through the sections although I
prefer to keep to the simple form herein described and illustrated.
The sections may be formed in or by any suitable machine, apparatus or method.
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 1
claim is :-
The improved section or block of earthenware or the like for use in the formation
of conduits for electric wires or cables and other analogous purposes, having a
longitudinal hollow or hollows B with ribs or ribs C and groove or grooves D for
jointing purposes substantially as described and illustrated.
