COMPLETE SPECIFICATION.
An Improved Block for use in Forming Conduits for Electrical or
other Cables or Wires, and for analogous purposes.
I JOHN PRICE Junior of Coppice Side Swadlincote in the County of Derby
Manager of Brick and Tile Works do hereby declare the nature of this invention
and in what manner it is to be performed to be particularly described and ascer-
tained in and by the following statement :-
The object of my invention is to provide a conveniently shaped block having and
running horizontally within it one or more channels or tubes of any desirable
sectional shape and area each of such channels or tubes being provided with a
specially formed spigot at one end and socket at the other end so that a continuous
and watertight conduit for the conveyance of electrical wires, lines or the like may
be formed by the use of such blocks when properly joined together and secured as
hereafter described.
Referring to the accompanying sheet of drawings
Figure 1. is an elevation of the spigot end of a block of such a shape as would be
suitable for use as a paving block as well as for a conduit.
Figure 2 is an elevation of the socket end of the same.
Figure 3. is a vertical section through centre of a channel and its joint in portions
of two such blocks and
Figures 4 and 5 are side elevations of the socket and spigot ends of this type of
block, respectively.
In the foregoing figures a flat block is illustrated of such a character as to render
it capable of being used as a portion of a pavement whilst acting at the same time
as a conduit for wires or the like and in order to make a watertight joint between
each and every block I form in each two separate sinkings at the socket end-the
first one A being of the same or similar sectional shape as the block and the second
one B being of the same sectional shape as that of the channel or tube and which I
prefer to be circular as shewn.
On the spigot ends I form double projections of corresponding shape C and D
which take into the sinkings A and B in the socket end of the next block so, when
a number of blocks are laid end to end, forming a continuous conduit.
A space is left as shewn by black shade E all round spigots and into this is
poured liquid cement through holes, such as F, in the block for the purpose and for
the escape of air.
Figures 6. 7. 8. 9. 10 shew a block of different shape and adapted to be sunk
beneath a pavement, the sockets and spigots being formed as before described and
the joints run with cement.
Figure 6 being a vertical section through the joint of two blocks.
Figures 7 & 8 side elevations shewing the socket and spigot ends respectively and
Figures 9 and 10 end elevations of sockets and spigots.
It will be seen that the blocks may be of any convenient length or shape and may
carry any desirable number of sockets or tubes each separately jointed as described
and I prefer to use earth or clay in the manufacture altho' other material may be
found equally available.
Having now particularly described and ascertained the nature of my said
invention and in what manner it is to be performed, I declare that what I
claim is-
For forming conduits for electrical lines of for analogous purposes the use of
suitably shaped blocks such as shewn in drawings having channels or tubes running
through their lengths furnished with sockets such as A. B and spigots such as C. D.

described and as illustrated by accompanying sheet of drawings.
