I JOHN HORROCKS of 25 Saunders St., Southport in the county of Lancaster
Engineer do hereby declare the nature of this invention to be as follows:-
To consist of a flue or stack which at the bottom shall have direct and uninter-
rupted communication with the drain, which carries the refuse from the watercloset,
and other waste water to the main street drain and which flue or stack may form
either a portion of the building of the premises, or be errected adjacent thereto
and may be built with the usual building materials or with iron or other suitable
material in casements for this purpose, the internal dimentions of which to be more
than sufficiently large to admit of a stationary or movable bason, which when in
position is placed under the nosle of the watercloset discharge pipe which when
filled with water formes a duplicate trap, thus when the ordinary watercloset
discharges by means of a connecting pipe, its refuse into the bason before named
this duplicate trap prevents (what frequently occurs in the discharge by ordinary
means of the contents of the closet) the admittance of any sewer gas into the
dwelling or premises to which it is attached.
It is proposed in some cases to form the lower end of the discharge pipe
from the water closet with a bend sufficient to form a trap to prevent sewage gas
ascending the discharge pipe.
At the point where the bason or nosle of the watercloset discharges into the flue
or casement, sufficient area will be left between the outside of the bason or dis-
charge pipe and sides of the flue, so as to allow the sewage gas to pass freely, and
ascend the flue. The flue may be carried to any conveient elevation and mounted
with a revolving ventelator or otherwise.
It is also proposed in some cases to heat the flue so as to create an increased air
current, so as more effectualy to draw and displace any sewage gas, this may be
accomplished either by hot water pipes, being so arranged as to enter the flue for
this purpose, or by one or more jets of gas, or any other heating arrangement •
which will best meet the circumstance of each seperate case.
In cases in which there is no opening in the main street drain near the
premises it is proposed to admit atmospheric air into the drain, at a point between
the street main drain and the flue before described, so as to form an intake or down
draft which air will travel the drain, and carry with it the sewage gas and ascend
the flue passing the watercloset connection in so doing.

I JOHN HORROCKS of 25 Saunders Street Southport in the county of Lancaster
Engineer do hereby declare the nature of my invention for IMPROVEMENT IN THE
TRAPPING OF WATERCLOSETS AND DRAINS AND VENTILATING OF SAME and in what
manner the same is to be performed to be particularly described and ascertained
'in and by the following statement:—
A flue or stack is to be erected having at its base direct and uninterupted com-
munication with the drain which carries off the sewage from the house &c to the
main street drain and this flue or stack may either form a portion of the building
of the premises or be erected adjacent thereto and may be composed of either the
usual building material or iron copper or glass or any other conducter of heat or
suitable material in casements adapted for the purpose Its interior shall be suffi-
ciently large to admit of a stationary or movable basin placed under the discharge
pipe of the watercloset which when filled forms a kind of duplicate trap-thus
when the ordinary watercloset discharges by means of its connecting pipe into
this basin this duplicate trap prevents the possibility of any noxious gas being
admitted into the dwelling house or premises.
The principle is shown by figure A. on plan A attached hereto-It is proposed
in some cases that the lower end of the discharge pipe from the watercloset should
have a sufficient bend to form a trap [without the addition of any basin] to prevent
the ascent of sewage gas into the house or premises.
In order that the sewage gas may have free passage upwards into the flue or
casement a sufficient space shall be left between the basin or discharge pipe and the
sides of the flue.
The flue may be carried to any convenient elevation and mounted with revolving
ventilators, discs or other similar appliance to which a fan shaft may be attached,
the fan being placed on the level with the drain or at any intermediate stage
between the drain and the top of the flue the fan to be driven either by the wind
or watermotor or otherwise.
In cases where there is no opening or grid in main street drain existing in the
immediate proximity of the dwelling house or premises atmospheric air can be
admitted by making an opening in the drain which communicates with the main
street drain and place therein a floating air stopping or trap at figures marked C
and erect a pillar mountaid with revolving discs with propelling air fan attached
as described above or worked by a watermotor.
It is also proposed in some cases to heat the flue so as to create an increased air
current and so effectually draw & displace the sewage gases the heating when the
flue or stack is constructed of glass copper or other easy conductors of heat to be
accomplished sometimes by the sun's heat or by the aid of hot water pipes inserted
in the flue or by gas jets or if the casement be constructed of fireproof material by
the insertion of a small grate above the duplicate trap in which gas coke or other
smokeless materials may be used.

page_text: One or more chambers of charcoal may also be placed near the top of stack
or flue to act as a deodoriser to the foul air.
It is intended that the same principal shall apply to the ventilation of street
drains by means of pillar flues see figure A on plan B attached, the motor being
one of wind acting upon revolving disc's with fans connected as before described or
watermotor as shown by figure B on plan B.
The upper section of the upcast pillar flue could be made of a transparent
material so warmed by the suns heat as to draw up the sewage gas [and also by
the means before described in the watercloset flue for same purpose the coke fire if
used being placed at the base of the pillar].
The air stoppings marked C. on plan may be placed at any convenient point the
sewer being ventilated in sections of from 200 to 1000 yds.
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 the following seperately or in combination one with another
1. Right of user of stacks or flues as described above.
2. Right of user of revolving dises or other similar wind appliance with fans
placed at any altitude of the stack or pillar flue or at the base for propelling the
air down the flue to the sewer and also a watermotor fan.
3. Right of user of revolving discs with fan in upcast stack shaft or pillar flue
driven either by wind or watermotor for propelling foul air up the flue.
4. Right of user of fire grating for coke or other sınokeless material at base of
upcast street pillar flue, and above duplicate trap in stack of watercloset.
5. Right of user of the upcast shaft or pillar flue when gas or heat of the sun
are wholly or partially relied on for creating an air current to raise the sewage
gas, the shaft at the base to be constructed of iron or other building materials and
the upper section of glass or other transparent material.
6. Right of user of chambers of charcoal in stack or pillar st. flue.
