PROVISIONAL SPECIFICATION.
Improvements in Dry Closets for the Treatment of Human
Excrements.
I EDWARD GREENWOOD Baker and Flour Dealer of 12 Enoch Street Miles
Platting in the City of Manchester and County of Lancaster do hereby declare
the nature of this invention to be as follows and in what manner the same is to
be performed and particularly described by the following statement:-
My invention comprises a structure within which human excrement can be dried
and effectually disposed of without the annoyance incidental to the use of water or
earth closets the prefered arrangement of said structure being briefly as follows
In an oblong hot water cistern made of galvanized iron or other metal I form a
trough or pan extending from end to end of the hot water cistern and making a
water tight joint with the same the bottom of the trough or pan forms part of
a circle and goes nearly to the bottom of the hot water cistern but leaving sufficient
cavity to allow the hot water to circulate round the trough or pan by this means
the trough or pan is kept hot.
For the purpose of drying the human excrements which drops into it through
the seat which I place at one end of the trough or pan and above the oblong hot
water cistern the other part of the trough or pan Ì cover with wood or metal so
that it can easily be removed to repair or replace a worm or conveyor which I
place near the bottom of the trough or pan and having a shaft in suitable bearings
which passes through the end of the cistern and made to revolve by a ratchet and
ratchet wheel and is connected to the lid which covers the seat by a connecting
rod so that each time the lid is raised the connecting rod imparts motion to the
ratchet wheel.and worm or conveyor and by this means the dropings are carried
along the bottom of the hot trough or pan to a pipe at the other end of the oblong
hot water cistern and thence to the flue or shaft which is connected with the
kitchen fire and by this means burned, it will be easly understood that the oblong
hot water cistern is connected by suitable pipes to the bath or kitchen boiler and
the heat can be regulated by a hot water tap. For the convience of burning the
dropings I place a perforated damper in the flue or shaft so that it can be opened
and the contents burned at times when the fire is not otherwise wanted.
The end of the trough or pan just below the seat is perforated to allow a current
of air to pass through the whole length of the hot trough or pan and the pipe to
the flue or shaft.
The liquid can be evaporated or run off by a separate pipe to the sewer or drain
as required.

Improvements in Dry Closets for the Treatment of Human
Excrements.
I EDWARD GREENWOOD Baker and Flour Dealer of No. 12 Enoch Street
Miles Platting in the City of Manchester and County of Lancaster 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 :-
My invention comprises a structure within which human excrement can be dried

page_text: and effectually disposed of without the annoyance incidental to the use of water
or earth closets the preferred arrangement of said structure being briefly as
follows:-
In an oblong hot water cistern a, made of galvanized iron or other metal I form
a trough or pan b, extending from end to end of the hot water cistern a, and
making a water tight joint with the same, the bottom of the trough or pan forms
part of a circle and goes nearly to the bottom of the hot water cistern a, but
leaving sufficient cavity to allow the hot water to circulate round the trough or
pan b, by this means the trough or pan is kept hot for the purpose of drying the
human excrements which drop into it through the seat c, which I place at one end
of the trough or pan b, and above the oblong hot water cistern a, the other part of
the trough or pan I cover with wood or metal d, so that it can easily be removed
to repair or replace a worm or conveyor e, which I place near the bottom of the
trough or pan b, and having a shaft e', in suitable bearings which passes through
the end of the hot water cistern a, and is made to revolve by a pawl e³, on a
levere, oscillating on the end of the shaft e', this pawl works upon a ratchet
wheel e, the lever, is connected to the lid c, which covers the seat hinged at c,
by a connecting rod e, so that each time the lid c, is raised the connecting rod e,
imparts motion to the ratchet wheel e, and worm or conveyor e, and by this means
the droppings are carried along the bottom of the hot trough or pan b, to a pipe b₁,
at the other end of the oblong hot water cistern and thence to the flue or shaft f,
which is connected with the kitchen fire and by this means the dried excreta is
burned. It will be easily understood that the oblong hot water cistern is connected
by suitable pipes to the bath or kitchen boiler and the heat can be regulated by a
hot water tap. For the convenience of burning the excreta 1 place a perforated
damper in the flue or shaft f, so that it can be opened and the contents burned at
times when the fire is not otherwise wanted. The end of the trough or pan just
below the seat is perforated with holes 6, to allow a current of air to pass through
the whole length of the hot trough or pan and the pipe b', to the flue or shaft f.
The liquid excreta can be evaporated or run off by a separate pipe to the sewer or
drain as required.
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
1st. The oblong hot water cistern a, and the trough or pan b, extending from
end to end of the hot water cistern on the accompanying drawing by which means
the cavity is formed for the hot water.
2nd. Heating the trough or pan b, by hot water from the bath or kitchen
boiler.
3rd. The worm or conveyor e, near the bottom of the trough or pan b.
