PROVISIONAL SPECIFICATION.
A New or Improved Method of Ventilating and Trapping
Fall Pipes.
I, CHARLES HENRY RILEY of Henry Street, Huddersfield, Yorkshire, Joiner
and Builder, do hereby declare the nature of this invention to be as follows:-
This invention refers to a new or improved method of ventilating and trapping
fall pipes and consists in combining the ventilating shaft and fall pipe so as to form
one pipe or shaft serving the two purposes of ventilating the drain with which it is
connected, and conveying the rain water from the eaves trough to the drain; and
also in trapping the same in order that noxious gases arising from the drain
cannot pass to the eaves trough and find their way into the interior of the
building.
In the present method of ventilating drains connected with dwelling houses and
other buildings, it is customary to attach a pipe to the side of the building having
communication with the drain and projecting above the eaves of the building so as
to discharge the foul gases into the atmosphere at a point clear of the building
itself; and alongside this ventilating shaft is placed the ordinary fall pipe for
conveying rain water from the eaves trough to the drain.
This arrangement is unsightly and, in many cases, the foul gases find their way
from the drain into the fall pipe and trough, and from the latter pass under the
slates or roofing into the building, vitiating the air therein and rendering it
unhealthy.
My invention is intended to effectually prevent the passage of sewer gases to the
eaves troughing and to make one pipe or shaft answer the double purpose of a
ventilating shaft and fall pipe which I accomplish by forming on the rough, a
downwardly extending pipe or funnel which enters a box trap attached to or
forming part of the ventilating shaft, the mouth of said funnel dipping into the
water contained in the trap. The trap is provided above the water line, with an
opening into the ventilator shaft and such shaft is coupled in any suitable manner
to the ordinary fall pipe communicating with the drain, said fall pipe and ventilator
shaft forming one clear thoroughfare for the passage of gases from the drain to the
atmosphere above the eaves of the building.
The trap, being fixed intermediate of the ventilating shaft and eaves trough,
effectually prevents the passage of noxious gases from one to the other and,
therefore, there is no possibility of such gases finding their way into the building as
is the case at present; the rain water collected in the troughing flows down the
depending funnel through the trap and overflows at the opening into the combined
ventilating shaft and fall pipe, down which it is conducted to the drain.
The trap is provided with a loose lid, by removing which, access can be had to the
interior of the trap for cleaning and like purposes.
The ventilator shaft and trap can be applied to any existing fall spout.

COMPLETE SPECIFICATION.
A New or Improved Method of Ventilating and Trapping
'
Fall Pipes.
I, CHARLES HENRY RILEY, of Henry' Street, Huddersfield, Yorkshire, Joiner
and Builder, 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 refers to a new or improved method of ventilating and trapping
fall pipes. In the present method of ventilating drains or sewers connected with
dwelling houses and other buildings, it is customary to attach to the side of the
building, a pipe having communication with the drain and projecting above the
building so as to discharge the foul gases into the atmosphere at a point clear of
the building itself, and alongside this ventilating shaft is a fall pipe or spout for
conveying rain water from the roof or eaves trough to the drain. This arrange-
ment is unsightly, and, in many cases, the foul gases from the drain find their way
into the fall pipe and eaves trough and from the latter pass under the slates or
roofing into the interior of the building, vitiating the air therein and rendering it
unhealthy.
My invention consists in combining the ventilating shaft and fall pipe to form
one pipe or shaft answering the two-fold purpose of ventilating the drain with
which it communicates and conveying rain water from the eaves or eaves trough of
the building to the drain, and in trapping said pipe or shaft in order that noxious
gases passing up the pipe cannot enter the eaves trough or find their way into the
interior of the building.
Such being the nature and object of my invention, I will now describe the same
more fully, and for this purpose have annexed drawings, wherein :-
Fig. 1 is a front elevation of a combined fall pipe or spout and ventilating shaft
with trap, to same constructed according to my invention.
Fig. 2 is sectional side elevation, and
Fig. 3 plan of same.
A is the combined fall pipe and ventilating shaft communicating at its lower end
with, the drain, or sewer and projecting a short distance above the eaves trough B
so, as, to discharge the noxious gases passing up said shaft from the drain into the
atmosphere at a point above and clear of the building, the projecting end of the
pipe or shaft being perpendicular as shewn in full line or bent over and carried up
the roof as indicated in dotted lines. The shaft A is provided with a hopper C cast
or.otherwise connected therewith, in which is a trap D filled with water to the level
of the outlet opening E in the shaft. The seal F of the trap projects below the
water line a sufficient distance to make ample allowance for evaporation.
The trough B is provided with a short depending funnel or pipe B' which enters
the hopper C or is otherwise arranged to deliver water from the trough into the
trap.D. from which said water discharges at the outlet E and flows down the shaft A
into the 'drain or conduit.
The trap D thus interposed between the eaves or eaves trough of the building
and the combined fall spout and ventilating shaft A effectually prevents the passage
of noxious gases from said shaft into the trough or under the eaves of the building,
therefore, avoiding all possibility of, said gases finding their way between the slates,
tiles, rafters or walls, into the building.
The flow of water from the outlet E runs down the sides of the shaft A thereby
leaving the central area or space thereof open for the updraught or free passage of
gases from the drain to the atmosphere and establishing a constant current of air
through the sewers and house drains. The hopper C is provided with openings a, a,
above or level with the water line in the trap, but having no communication with
the ventilator shaft excepting through the said trap. These openings or outlets

page_text: serve to discharge any overflow of water, as may happen during the early period of
a thaw when the roof snow or ice dissolves before the ice in the trap and cannot
therefore at first pass through the trap to the fall spout.
The hopper is fitted with a wire cover or other suitable lid G to prevent accumu-
lation of leaves or other matter therein, the same being removeable to give access
to the trap when required.
The combined ventilator shaft and fall spout with its trap and hopper may be
made to any design to be in keeping with the style of architecture of the building,
and where applied to existing fall spouts or ventilator shafts they are coupled
together as indicated at H.
Having now shewn and described my invention, and the manner in which the
same is to be performed, I would have it understood that I do not limit or confine
myself to the exact details of construction or to the exact shape or configuration of
the parts shewn, but what I do claim is :-
Firstly. A shaft or pipe A projecting above the eaves or eaves trough of the
building and communicating with the drain, answering the two fold purpose of a
rain water fall pipe and ventilator shaft provided with a trap intermediate of said
shaft and the eaves or eaves trough of the building in manner and for purposes
substantially as herein shewn and described.
Secondly. The combination, with a rain water fall pipe and ventilator shaft such
as A having an opening E therein, of a trap D and hopper C cast with said shaft or
suitably connected thereto and arranged between the eaves or eaves trough and
shaft A substantially as shewn and for purposes set forth.
Thirdly. The general construction and arrangement of parts substantially as
herein shewn and described for ventilating and trapping fall pipes.
