IMPROVEMENTS IN TROUGH OR MULTIPLE WATER CLOSETS
Year: 1881

page_text: LETTERS PATENT to Henry Bowes Scott and Harry Vaughan Rudston Read,
both of Broadway Chambers, Westminster, in the County of Middlesex,
for an Invention of "IMPROVEMENTS IN TROUGH OR MULTIPLE WATER
CLOSETS"
PROVISIONAL SPECIFICATION left by the said Henry Bowes Scott and
Harry Vaughan Rudston Read at the Office of the Commissioners of
Patents on the 17th February 1881.
HENRY BOWES SCOTT and HARRY VAUGHAN RUDSTON READ, both of Broadway
Chambers, Westminster, in the County of Middlesex. "IMPROVEMENTS IN
TROUGH OR MULTIPLE WATER CLOSETS."
Our Invention relates to trough or multiple water closets such as are employed
in factories or establishments where a number of persons have to be accommodated
at one time, our object being to provide simple means for preventing offence and
for clearing out the excreta. For this purpose under a number of closet seats, which
are most conveniently arranged in a line, we fix a trough having one of its ends
formed as a sloping weir beyond which is a suitable trap leading to a drain or
sewer.. This trough when in use is filled with water to the level of the weir, and
this water receives the excreta from the seats above. At suitable times a volume
of water is discharged into the end of the trough farthest from the weir, and this
water rushing along the trough flushes it, carrying the excreta or the principal
part of them over the weir to the drain or sewer. The flushing may be effected
automatically by combining with the trough a flushing tank and siphon or other
known selfacting apparatus for this purpose. Also the weir may be provided
with a siphon so arranged that when an addition is made to the contents of the
trough sufficient to start the action of the siphon, the trough will be rapidly emptied
by it and fresh water can then be run into the trough.

TROUGH OR MULTIPLE WATER CLOSETS."
Our Invention relates to trough or multiple water closets, such as are employed
in factories or establishments where a number of persons have to be accomodated
at one time, our object being to provide simple means for preventing offence and
for clearing out the excreta. For this purpose under a number of closet seats,
which are most conveniently arranged in a line, we fix a trough having one of its
ends formed as a sloping weir, beyond which is a suitable trap leading to a drain
or sewer. This trough when in use is filled with water to the level of the weir,
and this water receives the excreta from the seats above. At suitable times a
volume of water is discharged into the end of the trough farthest from the weir,
and this water rushing along the trough flushes it, carrying the excreta or the
principal part of them over the weir to the drain or sewer. The flushing may be
effected automatically by combining with the trough a flushing tank and siphon or
other known self acting apparatus for this purpose. Also the weir may be
provided with a siphon so arranged that when an addition is made to the contents
of the trough sufficient to start the action of the siphon, the trough will be rapidly
emptied by it, and fresh water can then be run into the trough.
The accompanying Drawing represents a trough or multiple closet arranged
according to our Invention; Fig. 1 is a longitudinal, and Fig. 2 a transverse
section; A is the trough, which may be of any suitable length. It is made with a
weir B at one end so as to retain a certain depth of water in the trough; C is a
tank provided with a flushing siphon D which is connected by a pipe with the
other end of the trough, so that when the water in the tank C, which may be fed
by a constant small supply, rises sufficiently high to start the siphon action, the
contents of the tank are rapidly discharged and flow along the trough clearing it
out. Instead of employing the tank and siphon, other means of supplying water
for flushing may be adopted, but we prefer the automatic siphon action as above
described. The discharging end of the trough instead of being made with a weir
as above described, may be provided with a siphon E and trap F, as shewn by the
part longitudinal section Fig. 3. In this case the siphon tank C and siphon D are
dispensed with, the trough being supplied constantly or intermittently as the case
may be.
When the liquid in the trough attains sufficient height to start the
siphon E, the contents of the trough will be rapidly discharged thereby.
Having thus described the nature of our Invention and in what manner the
same is to be performed, we claim,―
The combination of an intermittent siphon with the trough of a multiple water
closet, arranged and operating, substantially as herein described.
In witness whereof, I, the said Harry Vaughan Rudston Read, have hereunto
set my hand and seal, this Sixteenth day of August, in the year of our Lord
One thousand eight hundred and eighty one.
