PROVISIONAL SPECIFICATION.
An Improvement in the Construction of Water Closet Apparatus,
I, TOM STEVENS of Richmond Chambers Bournemouth in the County of
Southampton, Architect do hereby declare the nature of this invention to be as
follows:
--
The water being retained in the basin by means of a plug or plunger A and tho
plug being lifted by means of a handle B placed at the side of the basin, or by other
means the space required for the plug to work in is entirely covered & filled up by
water, thereby avoiding any accumulation of foul air in the apparatus during such
times as it is not in use.
The invention consists in the chamber C in which the plug works up and down
being so made as to be entirely filled up with water when not in use, while admitting
of the attachment to the rod B by which the plunger is worked of a lever or other
mechanical contrivance to regulate the flow of water to the basin.

COMPLETE SPECIFICATION.
An Improvement in the Construction of Water Closet Apparatus.
I, TOM STEVENS, of Richmond Chambers, Bournemouth, in the County of
Southampton, Architect, 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 :-
The main object of my invention is the construction of water closet apparatus, in
such manner,
as to avoid any accumulation of foul air therein, during such times as the
said apparatus is not in use.
Referring to the drawings filed with my provisional specification: :-
Fig. 1 is an elevation partly in section, and Fig. 2 is a sectional elevation through
the centre of Fig. 1 of a water closet apparatus constructed in accordance with my
invention. The water is retained in the basin by means of a plug, or plunger A, and
the said plug can be lifted by means of a handle B, placed at the side of the basin,
or the said plug may be operated by any other suitable device. The space O required
for the plug A to work in, is, as shewn clearly in Fig. 2, entirely covered and filled
up by water, thereby avoiding any accumulation of foul air, in the enclosed parts of the
apparatus, during such times as it is not in use. In order to effect this object, the
top of the chamber C, is kept a little below the surface of the water, in the basin,
the height of the said water may be adjusted by the ordinary regulating valves, in
general use, with an overflow pipe communicating with the trap under the apparatus.
The rod D, operating the plug A, passes through a stuffing-box, fixed in the top of
the chamber C. This rod is exposed above the stuffing-box, and such exposed part is
provided with a projection, so that when the rod is pulled upward, the said projection
moves a lever, or other suitable mechanical device, which actuates the apparatus
employed for discharging water into the basin. The basin may be made of earthen-
ware, metal, or other suitable material.
In practice I prefer to carry the aforesaid stuffing-box above the level of the water
in the basin, to avoid any chance of water leaking through it, and I may also provide
a downwardly projecting lip on the edge of the top of the chamber C, to direct the
flow of water downwards, when the plug A is lifted, but such lip is sloped upwards at
the ends, to the level of the top of the chamber to prevent the possibility of air being
confined behind it when the basin again fills with water.

page_text: I wish it to be understood that I do not confine myself to any particular apparatus
or device for discharging water into the basin, but 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. A water closet apparatus, having a plunger A, working within a chamber C, the
said chamber being so constructed, as to remain entirely filled with water at such
times as the apparatus is not in action, thereby avoiding any enclosed air space in the
apparatus, substantially as herein set forth.
2. A water closet apparatus, having a plunger A working within a chamber C, as
set forth in the preceding claim, and operated by a rod D, part of which is left
exposed to admit of the attachment thereto of the apparatus, which discharges tho
water into the basin, substantially as herein set forth.
3. A water closet apparatus, constructed in the manner and for the purposes,
substantially as herein described and shewn in the drawing accompanying my
provisional specification.
