PROVISIONAL SPECIFICATION.
Improvements in and relating to Channel Gulleys, Sinks, and Sink
Fittings.
We, J. DUCKETT AND SON LIMITED, of Sanitary Ware Works, Burnley, in the
County of Lancaster, JAMES DUCKETT, of Woodleigh, Burnley aforesaid, and
ALFRED DUCKETT, of Fern Royd, Burnley aforesaid, Manufacturers of Sanitary
Ware, do hereby declare the nature of this invention to be as follows:-
-
Our invention relates to improvements in channel gulleys, sinks and sink
fittings. Our object is to make these better adapted for their respective uses.
The first part of our invention relates to improvements in the channel gulley
for which Letters Patent No. 663 of 1893 were granted to James Duckett and
Alfred Duckett.
This gulley has a long narrow deep channel, curved in plan, and it works
admirably in conjunction with ordinary sink waste-pipes up to 1 inches diameter,
but with waste pipes of larger diameters the sink water has a tendency to splash
over the channel, and becomes objectionable.
In order to prevent this splashing, we cover a portion of the channel at the
inlet end preferably for about six inches of its length, and under this cover and
adjoining the inlet, we form a depression in the channel about three quarters of
an inch in depth. This depression holds a small quantity of water, and in com-
bination with the cover, acts as a cushion and prevents splashing.
We form an opening in the cover at the inlet end of the channel, which serves
a dual purpose, firstly to admit of ventilation to the foot of waste-pipe, and
secondly to enable a workman to make a good connection between waste-pipe
and channel.
A ridge is formed at inlet end of channel to prevent backflow of water into
foundations of adjoining building.
The second part of our invention relates to the construction of trapped sinks,
In order to make these strong, durable and sanitary, we make the sink, trap,
cover, and grid, preferably in one piece of glazed ware.
The outlet end of trap is undercut to receive a metal nipple with a dovetailed
end. The open space around the nipple is filled with cement or lead to secure
the nipple to the trap.
The waste-pipe is attached to the nipple by a set screw which enters a tapped
hole made in nipple.
This arrangement provides for easy removal of waste-pipe when required.
The grid is preferably made in one piece with the sink as above described, but
t may if desired be made in a separate piece of ware or metal. We fix at the
ower end of lead waste-pipe a hoop to protect it from injury.
In order that this part of our invention may be readily understood, we will
lescribe it by reference to the accompanying drawings wherein
Fig. 1 is a plan of a sink shewing a suitable position for trap and grid, but it
nay be varied if desired.

Improvements in and relating to Channel Gulleys, Sinks, and Sink
Fittings.
We, J. DUCKETT AND SON LIMITED, of Sanitary Ware Works, Burnley, in the
County of Lancaster, JAMES DUCKEIT. of Woodleigh, Burnley aforesaid, and
ALFRED DUCKETT, of Fern Royd, Burnley aforesaid, Sanitary Ware 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 follow-
ing statement:-
Our invention relates to improvements in channel gulleys, sinks and sink
fittings. Our object is to make them better adapted for their respective uses.
The first part of our invention relates to improvements in the channel gulley
for which Letters Patent. No. 663 of 1893 were granted to James Duckett and
Alfred Duckett.
This gulley has a long narrow deep channel curved in plan, and works admirably
in conjunction with an ordinary sink waste pipe up to 1 inches diameter, but
when this pipe is of larger diameter, the sink water has a tendency to splash
over the channel which is objectionable.
In order to prevent splashing, we cover a portion of the channel (say about
six inches) at the inlet end, and under this cover we form a depression in the
channel about three quarters of an inch deep. This depression holds a small
quantity of water, and in combination with the cover acts as a cushion, and pre-
vents splashing.
We form an opening in cover at the inlet end of channel, which serves
a dual purpose, firstly to admit of ventilation to the foot of waste pipe, and
secondly to enable a workman to make a good connection between waste pipe
and channel.
The said cover is made in one piece with the gulley.
A ridge is formed at inlet end of channel to prevent back flow of water into
foundations of adjoining building.
This part of our invention will be understood by reference to the annexed
drawing, in which Fig. 1 is a plan, and Fig. 2 a sectional elevation of our improved
channel gulley.
A is the covered portion at the inlet end of channel, made in one piece of ware
with the gullev. B, the channel. C the depression at the bottom of the channel
to hold a small quantity of water and to prevent splashing by checking the inrush
of water discharged from the sink waste pipe. D the opening at the inlet end
of channel to enable sink waste pipe to be fixed, and allow of ventilation.
The second part of our invention relates to the construction of trapped sinks.
In order to make these strong durable and sanitary, we make the sink, trap,
cover, and grid, preferably in one piece of glazed ware.

The waste pipe is attached to the nipple by a set screw which enters a tapped
hole made in the nipple.
This arrangement provides for easy removal of waste-pipe when required.
The grid is preferably made in one piece with the sink as above described, but
it may if desired be made in a separate piece of ware or metal. We fix at the
lower end of lead waste-pipe an iron hoop to prevent lead from injury.
The second part of our invention will be readily understood by reference to the
drawings accompanying our Provisional Specification, wherein
Fig. 1 is a plan of sink shewing a suitable portion for trap and grid, but such
position may be varied, if desired.
Fig. 2 is a longitudinal section shewing sink, trap, nipple, waste pipe and
grid.
Fig. 3 is a cross section of the same.
1 is the trap. 2 is the nipple. 3 is waste pipe. 4 is the grid. 5 is the set
screw.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:
1. The combination of a channel, depression, cover and inlet, in a dish or
channel gulley, substantially as described and illustrated.
2. The combination of a sink, trap, grid and nipple constructed and arranged
substantially as described and shewn on the drawings.
