IMPROVEMENTS IN WATER CLOSETS
Year: 1884

page_text: I WILLIAM MANGNALL, of Wellington Road Fallowfield, Manchester, in the
County of Lancaster, Architect and Surveyor do hereby declare the nature of
my said invention for "IMPROVEMENTS IN WATER CLOSETS" to be as follows :——
pan
My invention has for its objects, first to combine and form in one part the
or basin and trap of a water closet in order that there will be no joints to get out
of order, second to form in the pan or basin the water inlet for flushing the p pan or
basin right opposite to the outlet or channel leading to the trap for the purpose of
flushing the contents straight into the soile pipe and preventing the same from
getting into circular agitation in the pan or basin. To this end I cast or form the
pan or basin and trap of a water closet in one part either of iron with an enamelled
interior, of earthenware or any other suitable material and make the water inlet
and outlet opening right opposite each other. The channel leading from the pan
or basin to the soile pipe forming the trap may be of any suitable size and shape,
the end of which forms two branches or nozzles for the connection of soil pipe and
ventilating shaft. These nozzles are situated close to the trap in a vertical direction,
opposite to each other in order that the contents of the pan or basin may be
discharged into the soil pipe the moment it leaves the trap and the foul air or
sewage gas prevented from remaining in the trap or getting to the pan or basin and
permitted to escape or be drawn away from the trap or soil pipe by the ventilating
shaft more effectually.

page_text: COMPLETE SPECIFICATION.
I, WILLIAM MANGNALL, of Wellington Rd Fallowfield Manchester in the
County of Lancaster, Architect, do hereby declare the nature of my invention
for "IMPROVEMENTS IN WATER CLOSETS" and in what manner the same is to be
performed to be particularly described & ascertained in and by the following
statement:
My invention has for its objects first, to combine and form in one part the pan
or basin and trap of a water closet, in order that there will be no joints to get out
of order, second to form in the pan or basin the water inlet for flushing the pan or
basin right opposite to the outlet or channel leading to the trap for the purpose of
flushing the contents straight into the soil pipe and preventing the same from
getting into circular agitation in the pan or basin.
And in order that my invention may be better understood I have caused to be
appended hereunto one sheet of drawings marked with letters of reference indicating
like parts in the various figures.
Fig 1 is a longitudinal section.
Fig 2 is a plan of the closet pan and trap.
In carrying out my invention I cast or form the pan or basin a and trap b of a
water closet in one part either of iron, with an enamelled interior of earthenware,
or any other suitable material and make the water inlet c and outlet opening d
right opposite each other.
The channel e leading from the pan or basin to the soil pipe f forming the trap b
may be of any suitable size and shape the end of which forms two branches or
nozzles g & h for the connection of soil pipe f & ventilating shaft i.
These nozzles are formed close to the trap in a vertical direction opposite to each
other in order that the contents of the pan or basin may be discharged into the soil
pipe the moment it leaves the trap band the foul air or sewage gas prevented
from remaining in the trap or getting to the pan or basin and permitted to escape
or be drawn away from the trap or channel e by the ventilating shaft i more
effectually.
The portion of the channel e between the trap b and the nozzle g of the
ventilating shaft i, is formed in such a manner that the foul air, directly it has left
the trap 6 will at once be permitted to rise and take a straight course to the
ventilating shaft i and drawn away by the latter instead of the course of the foul
air being interrupted and prevented from immediately rising after leaving the
trap b.
This very important feature of my invention, also applicable to existing water
closets, is obtained by forming the nozzle g for the connection of the ventilating
shaft in a line with the channel e, but above the level of the water in the trap b
and above the nozzle of the soil pipe f.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
(1) In a water-closet, forming the pan or basin and trap in one piece, and in
such a manner that the water inlet will be opposite to the outlet channel as
set forth.
(2) The particular formation and arrangement of nozzle to which the ventilating
shaft is connected, and mode of carrying away the foul air as set forth.
Dated this 8th day of June A.D. 1885.
