Improvements in or connected with Inspection and like Chambers
for Drains.
We, THE ALBION CLAY COMPANY LIMITED, of Woodville, near Burton-on-Trent,
and in the County of Leicester, and ARCHILBALD WALTER BIRD, of 26, Chaucer
Road, Herne Hill, in the County of London, Draughtsman, do hereby declare the
nature of this invention to be as follows:-

This invention relates to gullys and like receptacles, or chambers, to intercept
sewer gases, or retain matter from drain pipes, or the like, or for inspection pur-
poses, and has for its object to provide a gully, receptacle, or chamber, (we will
refer to it as a gully for brevity) into which any desired number of drain pipes
can be led without objectionable bends therein, and which can be placed at any
required depth in the ground without the necessity for brickwork and "
rendering" to bring the top of the gully to the ground level. According to this
invention the gully is made in separable pieces consisting of a bottom part forming
the receptacle and trap proper and a cylindrical middle piece, or pieces, which is,
or are, mounted upon the said bottom part, so as to bring the upper part, with
round, square, or other shaped top, to which the grating, or cover, is applied, to
the ground or other desired level. The parts are adapted to be mounted upon
each other by flange and socket, or other suitable connections, or joints, so that
they can be turned, or angularly displaced relatively to each other and as the
outlet from the gully is formed on the bottom part, and the connections for the
inlet drain pipe or pipes are in the piece, or pieces, mounted upon it the said
connections for the said drain pipe or pipes can by rotating, or angularly displacing
the said piece or pieces, be brought into any desired position to suit the said drain
pipe or pipes without disturbing the position of the outlet. If a square, or other
non-circular grating, or cover, be used the top piece can be formed of corresponding
shape at its upper part, and at its lower part be made round so that it can be turned
into any position to suit the position which the grating or cover is to occupy.
Where two or more, upper pieces are used there may be connections on each,
or both, of them, for the inlet drain pipes to suit drain pipes which meet the gully
at different levels. For convenience of inspection of the drain leading from the
outlet, the outlet bend can be provided with an opening with a pipe leading to the
surface of the ground the said pipe being formed of pieces connected by flange and
socket joints or other suitable connections and of a depth corresponding to the depth
of the pieces forming as aforesaid the body of the gully above the bottom part.
Although we have mentioned gullys in the foregoing description it is to be
understood as before stated, that the invention is applicable generally to recep-
tacles, or chambers, into which drain pipes enter.

Improvements in or connected with Inspection and like Chambers
for Drains.
We, THE ALBION CLAY COMPANY LIMITED, of Woodville, near Burton-on-Trent,
and in the County of Leicester, and ARCHIBALD WALTER BIRD, formerly of 26,
Chaucer Road, Herne Hill, in the County of London, but now of 1, St. Helena
Terrace, Richmond, in the County of Surrey, Draughtsman, 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:-
-
This invention relates to inspection and like chambers, such as man-holes, for
drains, and has for its object to provide a chamber, into which any desired number
of drain pipes can be led without objectionable bends therein, and which can extend
to any required depth in the ground without the necessity for brickwork and
cement-rendering to bring the top of the chamber to the ground level.

We will describe our invention by reference to the accompanying drawings
in which
Figure 1 is a vertical section of a chamber constructed according to our
invention.
Figure 2 is a plan thereof and Figure 3 is a vertical section of an extension
piece which may be used in the construction of the said chamber.
Like letters of reference indicate like parts throughout the different figures
of the drawings.
According to this invention the chamber is made in separable pieces consisting
of a bottom part A forming the receptacle and trap proper and a cylindrical or,
as shewn in Figure 1, a conical middle piece, B, or pieces, BB, which is, or are,
mounted upon the said bottom part A, so as to bring the upper part C, with square
top c to which the grating, or cover, is applied, to the ground or other desired level.
The parts A, B B and C are adapted to be connected to each other by spigot and
socket, or other suitable connections, or joints, so that they can be turned, or
angularly displaced, relatively to each other, and as the sewage outlet a is formed
on the bottom part A, and the connections bbc each for an inlet drain pipe, are
in the piece B, or pieces B and C, mounted upon it, the said connections bbc can,
by rotating, or angularly displacing, the said piece, or pieces, be brought into any
desired position to suit the drain pipe or pipes, without disturbing the position
of the outlet a. The top piece C is formed of square shape at its upper part, and
round at its lower part, so that it can be turned into any position to suit the
position which the grating, or cover, to be applied to the top of the chamber, is
to occupy
Where two, or more, upper pieces are used there may be connections on each,
or both, of them for the inlet drain pipes to suit drain pipes which meet the gully
at different levels. For example, in Figure 1 wherein two such upper pieces BC
are shewn, the middle piece B is represented as provided with the two connec-
tions 66', and the upper piece C is represented as provided with the connection C¹,
each of the pieces BC may however have more or less than two connections;
if desired the connection c¹ may be employed for admitting fresh water into the
chamber, instead of using the said connection for the admission of sewage matter.
For convenience of inspection of the drain leading from the outlet a, the outlet
bend can be provided with an opening a with a pipe a leading either. to the
surface of the ground, or as shewn in. Figure 2 through the piece B³, the said pipe
being formed of pieces connected by flange and socket joints, or other suitable
connections.

page_text: When the floor or bottom 63 of the before described chamber is considerably
below the ground level, we fill the space between the said part 62 and the surfaco
of the ground with square and preferably internally glazed extension pieces D
Figure 3 fitted together by means of socket and spigot or other suitable joints by
which means we are able to produce, without brickwork or cement-rendering a
chamber having a smooth interior surface which may be more readily cleaned
than those as hitherto constructed.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, we declare that what we
claim is;-
An inspection or like chamber for drains comprising a bottom part having a
sewage outlet, and an upper part or upper parts having a sewage inlet or two or
more such inlets jointed to the bottom part so that the relative angular position
of all these parts may be varied, the uppermost of the parts having a square top,
substantially as hereinbefore described and illustrated in the accompanying
drawings.
