PROVISIONAL SPECIFICATION.
Improvements in and relating to Channelled Gulleys for Sinks,
Baths, and Lavatories, and for Rain Water.
We JAMES DUCKETT and ALFRED DUCKETT, of Mitre Brick Works, Burnley,
in the County of Lancaster, Brick and Sanitary Pipe Manufacturers, do hereby
declare the nature of this invention to be as follows:-
A rectangular channelled block made in one piece of earthenware, by preference
about 28" x 11" x 4", but may be of any desired size.
The block when in position is laid with one of its longer sides against the wall or
building. A curved or other suitable open channel conducts the water from sink
waste pipe into a trap fixed under one end of the block (at the opposite end to which
the waste enters). The gully and channel are long enough and wide enough to
receive two or three waste pipes in addition to that for sink waste.
The bottom of one part of main channel is sunk deeper & to a smaller radius.
A round opening is formed through the outlet end of block, for waste water to
pass through on its way to the trap.
In the said opening we fix two iron hinged grates to lean or slope rapidly
towards each other leaving a space about five eights of an inch wide between the
two grates.
At the bottom of this opening, we make a circular rim projecting below the
bottom of block, to fit socket of trap.
The trap is provided with an exceedingly small water space, barely leaving suffi-
cient hand room for cleansing purposes, although one object of this invention is to
provide a self-cleansing gulley so as to meet all sanitary requirements, & for this
purpose the trap is placed about eighteen inches away from sink waste pipe, to
prevent sewer gas from entering the dwelling.
We form a sloping opening through the side (near one end of block) to receive
sink waste pipe. Over this opening we form a suitable cover or shield to protect
the end of waste pipe from wilful or accidental damage.
By preference we curve the channel at the inlet end & in order to cause the
stream to follow the curve without splashing over, we make the near side of channel
to overhang so as to deflect the stream in the proper direction, but this result may
be obtained by other contrivances.

Improvements in and relating to Channelled Gulleys for Sinks,
Baths, and Lavatories, and for Rain Water.
We JAMES DUCKETT and ALFRED DUCKETT of Mitre Brick Works, Burnley
in the County of Lancaster, Brick and Sanitary Pipe Manufacturers, 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:-
A rectangular channelled gulley block is made in one piece of earthenware by
preference about 28 x 11 x 4 inches, but may be of any desired size.
This block when in position is laid with one of its longer sides against the wall or
building

page_text: A curved or other suitable open channel conducts the water from sink waste pipe
into a trap fixed under one end of the gulley block (at the opposite end to that at
which the waste enters. The gulley and channel are long enough and wide enough
to receive two or three waste pipes in addition to that for sink waste.
At the bottom of one part of main channel it is sunk deeper, and to a smaller
radius.
A round opening is formed through the outlet end of block for waste water to pass
through on its way to the trap.
In the said opening we fix two iron hinged grates to lean or slope rapidly
towards each other leaving a space about five eights of an inch between the
two grates.
At the bottom of this opening we make a circular rim projecting below the
bottom of block to fit socket of trap.
The trap is provided with an exceedingly small water space barely leaving suffi-
cient hand room for cleansing purposes.
One object of this invention is to provide a self-cleansing gulley so as to meet all
sanitary requirements, and for this purpose the trap is placed about eighteen inches
away from sink waste pipe, to prevent sewer gas from entering the dwelling.
We form a sloping opening through the side (near one end of block) to receive
sink waste pipe.
Over this opening we form a suitable cover or shield to protect the end of waste
pipe from wilful or accidental damage.
This shield is made in one piece with block.
By preference we curve the deeper channel at the inlet end, and in order to
cause the stream to follow the curve without splashing over, we make the near side
of channel to overhang so as to deflect the stream in the proper direction, but this
result may be obtained by fixing a metal or other shield to partially cover the
narrow channel or other contrivances.
In order that the invention may be readily and clearly understood and carried
into effect we have appended hereto a sheet of drawings illustrative thereof, and
will now proceed to describe the same by the aid of letters and figures to shew its
practical application.
Figure 1. is a plan or horizontal elevation looking on top of channelled gulley
block.
Figure 2. is a longitudinal sectional elevation, and
Figure 3. is a transverse section.
a. is the channelled gulley block, a is the main channel, a' is the extra con-
tracted channel, a² is the shield to protect lead sink waste pipe, a³ are the sloping
hinged grates. is the trap, c is the outlet to drain, d is the sink waste pipe, e may
be the rain water, bath or lavatory waste pipes, and f the ground line, 9 overhanging
channel.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed we declare that what we
claim is :-
1. The use, construction, and application of earthenware channelled gullies,
formed and fixed substantially as described and illustrated.
2. In a channelled gulley the formation of a shield for sink waste pipe, in one
piece with the channelled gulley block, substantially as illustrated and described.
3. In a channelled gulley the fixing and use of two sloping hinged grates, in an
inclined position, placed substantially.as illustrated and described.
4. The formation and use of an extra contracted channel within the main channel
substantially as illustrated.
5. Forming the said channel undercut, or fixing a metal or other shield to
partially cover the narrow channel, (or similar device) to prevent splashing, sub-
stantially as set forth and illustrated.

page_text: 6. The self cleansing trap of the peculiar. form and proportions as illustrated in
combination with a channelled gulley, substantially as illustrated and for the
purpose set forth.
