JOSEPH MAY THRUSH Chapel Street, Ripley Dorbyshire House Agent do hereby
declare the nature of this invention to be as follows:-
These Traps to be made of any material, are fixed in continuation of the drain with
socket to connect. A trough is formed below the drain in which is a frame and
slide or sluice to regulate the dip up or down. When the slide dips, it is a stench
trap. When lowered to bottom of trough, it stops the opening in the drain, and
when drawn up the whole drain is open.
The trough is formed so that when the slide dips, the full bore of water may pass
down the drain. If required for cleansing or any other purpose, it may be drawn to
the top or out of the way altogether. They may be single, or double with inlet and
outlet. The trough may be made to take in four or more drains, and all be trapped
or stopped or slide removed for flushing or ventilating purposes.

page_text: JOSEPH MAY THRUSH Chapel Street Ripley Derbyshire House Agent 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:
Stench traps for sewers, drains, closets, sinks, rainwater-cistern overflow pipes, and
all connections requiring trapping, and to be used for flushing when required.
The sink trap either bell or any other form is supplied with a screw or other means
to regulate the dip lip so that the outlet into the sewer may be stopped up when
required.
The single trap for drains is a rectangular or other shaped receptacle A B deep
enough to allow a full bore of water to pass into the drain if required when the lip is
down in the water. The outlet is formed to fit into the drain if required. The lip
to dip into the receptacle to trap the stench is fitted into a slide or frame, and may be
moved down to stop the opening into the drain, or taken out for cleansing the
receptacle A B. The double trap for drains is a rectangular or other shaped receptacle
deep enough C to allow a full bore of water to pass down the drain if required when
the inlet and outlet lips or dips are down in the water to form stench traps. The
inlet and outlet are formed to connect the drain in a line with the drain, and the
receptacle is below, as described above.
The receptacle is sloped off at both ends to allow a free passage down the drain to
cleanse the receptacle for lips or dips.
The lips or dips into the receptacle are fitted to slide in frames or slides as above,
and may be moved down to stop the openings in and out of the trap or receptacle,
when the drains may be flushed by filling or part filling the hole with water, and
then drawing up the slides. The sough or drain grato is let into the stone or other
cover, as no grate is required in the stonch traps.
If only required for ventilation and flushing, any ordinary cover perforated will
suffice. The traps for four or more drains, or openings into the receptacle, and man
hole or opening down to the drain are all fitted with frames and slides which may be
let down to dip in the water in the receptaclo A B formed lower than the drain and
form stench traps to all the openings in the drains, be lowered to bottom to stop
all or any of the above named openings or drains, or be raised for flushing,
cleansing the receptacle, and drains, or ventilating. These combined stench traps,
flushing apparatus, ventilators, and purifiers, may be made of any suitable material,
and may be used for either small or large drains or sewers: or any connections
between drains, or sewers, to cistern overflows, likewise-any communications where
foul air, gas or any other stench requires trapping or stopping or purifying. They
may be fixed fast or one fast and other loose, and can be regulated if loose by fingers
or rod and hand, or by screw as sluice valves: may be placed with small expense
almost anywhere; There seems to be no limit, scarcely to their usefulness.

page_text: The water in the trough being impregnated with foul air, is either purified or
carried away by the continual currant down the sewer, to be regularly supplied with
other water which may in turn purify, or carry off the gas, or foul air or any other
impure matter.
The following are my own inventions or features of novelty as far as I know.
In all stench traps of this kind I claim the raising and lowering of the dip either
slide bell, or any other form of dip, to Trap the stench in water closets, privies,
sinks, drains, outlets for rain water &c. to sewers or the like. The slope for cleansing
the receptacle, for dips or lips ( The trapping of two or more drains in one
receptacle. The forming and laying the trap in continuation of the drain when
required. The dispensing with grate in the trap when required, and for the com-
bination for preventing of stink or stench and flushing or cleansing the receptacle for
the above. Also for water cistern syphons which may be examined if dry. Surface
water may be run into man holes and trapped. The screw through the bell trap is
for stopping the opening when families are going away. The movable dip is at work,
or in use upon my premises, and has been for more than seven years and may be
seen by any properly authorized person. It is merely a damper & frame for an
ordinary uniform fireplace.
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. The raising and lowering of the dip.
