COMPLETE SPECIFICATION.
Improvements in Water Closets.
I, SAMUEL GEORGE DUTTON, of 414, Upper Manor Street, Chelsea, in the
County of London, Wood Carver, 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 :-
This invention relates to water closets, and comprises improvements in the basin,
and in and relating to the discharge valve, and in and relating to the discharge
funnel and trap and to the junction of the same with the soil pipe. The invention
is illustrated in the accompanying drawings forming part of this Specification
wherein :-
Figure 1 is a sectional elevation of a water closet constructed according to my
invention.
Figure 2 is an elevation of the same viewed from the front and having the cover
removed from the discharge funnel.
Figure 3 is a side elevation shewing the method I adopt for opening and closing
the discharge valve simultaneously with the opening and closing of the waste
preventer plug.
Figures 4 to 8 are views of the various parts shewn separately.
The same letters of reference represent similar parts in the various figures.
According to my said invention I make the basin, A, and the discharge funnel, B,
and trap, B', in one piece of earthenware or other suitable material, the com-
munication between the said basin and the said discharge funnel being arranged so
that it forms a short outlet piece, C, opening towards the front of the basin for the
purposes hereinafter described. In some convenient part of, preferably in front of,
the funnel, B, I provide an opening, D, see Figure 2, over which is fitted a door or
cover, E, having a groove or recess, a, around the border thereof, for the purpose
of receiving a strip of india rubber or other suitable material for making an
I attach this cover
airtight joint between the said cover and the discharge funnel.
which may be of earthenware, metal, or other suitable material to the said funnel
by means of wire or the like passed round the lugs, b, b', formed on the cover and
funnel respectively, or the said cover may be secured by clamps or by other
suitable contrivances.
To the short outlet piece, C, I attach by means of some suitable cement, a valve
seating, F, see Figures 1 and 6, provided with a hinge, and having a groove, c
(seen more clearly in Fig. 6) for the reception of a ring or washer of india rubber
or other suitable material. To this valve seat I fit a valve G, also having a
groove d, corresponding in position to the groove, c, in the valve seating and into
which the rubber or other ring enters when the valve is closed thus making an
airtight joint.
1 affix the said valve to the spindle, H, which passes through an opening in one
of the sides of the funnel, thence through the hinged parts of the valve and valve
seating and finally enters the boss or depression, f, in the opposite side of the said
funnel.
I provide a lignum vitæ or other bearing, g, for the spindle at the part where it
passes through the walls of the funnel, or in lieu of such bearing I niay provide a
stuffing boss of suitable material. In some cases I fit a similar bearing in the boss
or depression, f.
For the purpose of keeping the said discharge valve closed, I affix to the
spindle, H, a short crank, /, to which I attach a weight I.
I prefer to arrange that the discharge valve shall be opened simultaneously with
the pulling of the waste preventer plug. I effect this by means of a disc, J, having

page_text: two grooves i. 1 cut around its circumference and adaptel to work in the casing, K,
which I fix in any convenient position. To the said disc I fix a short spin.lle, j,
one end of which works in a bearing provided at the back of the said casing ani
the other passes through the cover, L, of the same. To this spindle is fitted the
handle, k. I attach to one of the said grooves a pull, , of wire or other suitable
material which I connect to a sheave or grooved disc, M, attached to the spin.lle of
the discharge valve and which for convenience I pass under an intermediate
sheave, N, and to the other groove I fix a similar pull, ', which is connected to the
waste preventer plug, in such a manner that the two pulls move in opposite
directions.
Thus by turning the handle, k, the discharge valve, G, is opened simultaneously
with the flushing of the basin, and by releasing the sail handle, the said valve
immediately closes by reason of the balance weight, I, which ten is to keep it shut.
Provision is made to ventilate the discharge funnel by means of the pipe, O.
An overflow channel, Q, is also provided in the basin.
I connect the trap, B', to the soil pipe, P, by means of a union so constructed
that it enables the joint between the said trap and the said soil pipe to be more
readily and efficiently made or disconnected than by the means hitherto in use.
The upper part of this union shewn in section in Figure 1 and in plan in Figure 4,
I provide with a circumferential groove or depression, m, between which and the
exterior of the union I form communications by drilling holes, e, e, through the
flange thereof for the purposes hereinafter described. I also provide a raised or
projecting rim, o, adapted to fit loosely into the recess, p, of the lower part of the
said union, shewn in section in Figure 1, and in plan in Figure 5 thereby forming
an annular space around it.
In making the joint I proceed as follows. Having secured the upper part of the
union to the end of the trap, B', by means of suitable cement, I turn the lead soil
pipe over so as to form a flange to fit the recess, p, and 1 secure the said soil pipe
to the lower part of the union by means of a soldered joint. Upon the lead flange
I place a small quantity of putty or other suitable material whereon the projecting
rim, o, is bedded. The two parts of the union are now to be bolted together so
that the flanges thereof fit closely, and to complete the joint I introduce into one
of the holes, e, e, provided for the purpose, a sufficient quantity of melted hard
paratin, or a mixture of hard and soft paraffin, to all the circumferential groove, m,
and any other cavities that may exist between the upper and lower parts of the
union.
When it is desired to disconnect this union, I apply sufficient heat thereto to
melt the parathin when the parts can be withdrawn.
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 :-
:―
I. A water closet having the basin provided with an outlet, C, opening towards
the front thereof, to which is fitted the discharge valve, G, in the manuer
hereinbefore described and illustrated in the drawings.
II. A water closet having the basin provided with an outlet, C, opening
towards the front thereof, fitted with the discharge valve, G, and the discharge
funnel, B, having the opening, D, to which is fitted the cover, E, substantially as
hereinbefore described and illustrated in the drawings.
III. In a water closet, the combination of the trap, B', with the union, R,
constructed substantially as described and illustrated in the drawings.
IV. The combination of the grooved disc, J, and casing, K, Figures 3, 7 and 8,
with the discharge valve, G, as and for the purposes described and illustrated in
the drawings.
