Improvements in Water Closets and the like.
Year: 1897

page_text: Improvements in Water Closets and the like.
I, RICHARD BROWN EVERED, of 27, Drury Lane, in the County of Middlesex, do
hereby declare the nature of this invention to be as follows:-
According to this invention the depression of the seat when the closet is in use
admits water to a closed air vessel and the raising of the seat after use by a counter-
balance weight or otherwise cuts off the supply and discharges the contents of the
vessel into the closet basin. By this arrangement noise is avoided and the vessel
being normally empty is not liable to injury by frost.
The seat has fixed to it an arm operating the lever of a three way cock the passages
in the plug of which are so arranged that when the seat is raised the supply is cut
off and the vessel connected to the basin and when lowered the supply is opened
and the vessel cut off from the basin. The three way cock may be replaced by
an arrangement on the principle of a sluice valve or one of the diaphragm
kind.
The apparatus may be worked by a footboard and is applicable to urinals and
other places.

I, RICHARD BROWN EVERED, of 27, Drury Lane, in the County of Middlesex, 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:
According to this invention the depression of the seat when the closet is in use
admits water to a closed air vessel and the raising of the seat after use by a counter-
balance weight or otherwise cuts off the supply and discharges the contents of the
vessel into the closet basin. By this arrangement noise is avoided and the vessel
being normally empty is not liable to injury by frost.
The seat has fixed to it an arm operating the lever of a three way cock the
passages in the plug of which are so arranged that when the seat is raised the supply
is cut off and the vessel connected to the basin and when lowered the supply is
opened and the vessel cut off from the basin. The three way cock may be replaced
by an arrangement on the principle of a sluice or disc valve or one of the diaphragm
kind.

page_text: The apparatus may be worked by hand or by door or footboard action and is
applicable to urinals and other places.
Figures 1 and 2 are side elevations of a water closet constructed according to
this invention the seat being shown in different positions. Figure 3 is a plan of
the lower part of Figure 1. Figures 4 to 6 are sections at right angles to each
other of the three way cock.
a is the closet basin, b the seat and c a closed air vessel connected by the pipe d
to the three way cock e the latter being also connected by a pipe f to the basin and
by a pipe g to the water supply. h and j are plates fixed to the underside of the seat
and formed with eyes serving as hinges. The eye of the plate his circular and fits
over a circular portion e' of the case of the three way cock e whilst the eye of the
plate jis square and fits over the square end 2 of the plug of the cock which is
therefore turned when the seat is raised or lowered. The plate j is prolonged rear-
wards and has a counterbalance weight k fixed to its end so that the seat normally
assumes the position shown at Figure 2 bringing the plug of the cock into the position
shown in Figures 4 to 6 so that the vessel c and pipe d normally contain no water
and the risk of damage by frost is minimised. When the seat is depressed the
pipe g is put into communication with the pipe d and water flows into the vessel c
compressing the air in it.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. Water closets and the like provided with an air vessel open to the water supply
when the closet or the like is in use and to the basin when it is out of use.
2. Water closets and the like substantially as described with reference to the
drawings.
