APPARATUS TO BE APPLIED TO WATERCLOSETS."

DAVID GILL, of Weston-super-Mare; in the County of Somerset, Plumber.
IMPROVEMENTS IN VENTILATING APPARATUS TO BE APPLIED TO WATERCLOSETS."
This Invention consists in the construction and arrangement of apparatus to be.
applied to waterclosets for the purpose of ventilating the same, and of preventing"
the emanation therefrom of noxious and unpleasant effluvia.
The apparatus is mainly operated by the opening and closing of the lid flap of
the closet seat.
Below the pan for the excreta a channel is provided, the same being connected
by two pipes, by which the fumes pass from a box which is placed below the pan
or excreta receptacle, to the upper part of the latter, and thence over its contents.
to a shaft, by which they are carried to the outer air to an elevation above the closet.
Two modifications are embraced by this Invention, the first of which relates
exclusively to the ventilation of the closet pan. This object is effected by allowing.
the external air to pass throughi än inlet pipe provided for that purpose into the
before-mentioned chamber, which may be termed the fumous chamber, and thence
through a suitable pipe or channel to the upper portion of the pan over the contents
of the latter, the current of air then passing through an exit shaft to an elevation
above the closet.
In the "fumous chamber" are placed, if desired, disinfecting or deodorizing'
substances, which, in passing over the contents of the pan, neutralize noxious or
unpleasant effluvia emanating therefrom.
The second modification embraced by this Invention relates to the ventilation of
the apartment only in which the closet is situated when the lid of the seat is closed,

page_text: and the closet not in use. The external inlet air is allowed to pass through an
inlet pipe into an air box furnished with an automatically acting flap or lid, and
thence through the riser of the seat of the watercloset to a channel or pipe, which
is provided with a suitable valve, by which the air in the apartment is allowed to
escape.
The several pipes or channels employed for the purpose of ventilation are operated
by means of wires and levers or other suitable appliances in connection with the
flap or lid of the watercloset. The latter is rendered air-tight by means of
vulcanized india-rubber bands and flanges.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said David Gill in, the Great Seal Patent Office on the 16th February
1878.

"IMPROVEMENTS IN VENTILATING APPARATUS TO BE APPLIED TO WATERCLOSETS."
My said Invention consists in the construction and arrangement of apparatus to
be applied to waterclosets for the purpose of ventilating the same, and of preventing
the emanation therefrom of noxious and unpleasant effluvia.
The apparatus is mainly operated by the opening and closing of the lid flap of
the closet seat.
Below the pan for the excreta a channel is provided, the same being connected by
two pipes, by which the fumes pass from a box which is placed below the pan or
excreta receptacle, to the upper part of the latter, and thence over its contents to a
shaft, by which they are carried to the outer air to an elevation above the closet.
Two modifications are embraced by this Invention, the first of which relates
exclusively to the ventilation of the closet pan. This object is effected by allowing
the external air to pass through an inlet pipe provided for that purpose into the
before-mentioned box or chamber, which may be termed the "effluvia chamber,"
and thence through a suitable pipe or channel to the upper portion of the pan over
the contents of the latter, the current of air then passing through an exit shaft to
an elevation above the closet.
In the "effluvia chamber" are placed, if desired, disinfecting or deoderizing
substances, which, in passing over the contents of the pan, neutralize noxious or
unpleasant effluvia enianating therefrom.
The second modification embraced. by this Invention relates to the ventilation of
the apartment only in which the closet is situated when the lid of the seat is closed,
and the closet not in use. The external inlet air is allowed to pass through an
inlet pipe into an air box furnished with an automatically acting, flap or lid, and
thence through the riser of the seat of the watercloset to a channel or pipe, which is
provided with a suitable valve, by which the air in the apartment, is allowed to
escape.
.
The several pipes or channels employed for the purpose of ventilation are operated
by means of wires and levers, or other suitable appliances in connection with the
flap or lid of the watercloset. The latter is rendered air-tight by means of
vulcanized india-rubber bands and flanges.

page_text: In the annexed Drawing A is the closet basin or pan; B, the trap; and C, the
soil pipe; D is the effluvia chamber; E, the air inlet; and F, F, the effluvia exit
pipe; G, G, are the flushing pipes provided with india-rubber valves; H is the exit
air pipe. The flushing valve and cistern are shewn at I, and the ring pull to the
same at K; L is the outlet ventilator; M, the lever on the lid to open the venti-
lator; N is the inlet ventilator; and O, the automatic flap to the same; P is the
ventilating pipe of the soil pipe; and Q, the india-rubber for rendering the flap or
lid air-tight.
Having thus described and ascertained the nature of my said Invention and
in what manner the same is to be performed, I would observe in conclusion that
what I consider novel and original, and therefore claim as constituting the
Invention secured to me by the said herein-before in part recited Letters Patent
are,-
"
First. The use and application of an inlet pipe by which air is carried into an
effluvia chamber," and thence to the upper portion of the pan of a watercloset,
substantially as and for the purposes herein-before described and set forth.
And, Secondly. The use and application of an inlet pipe by which the air is
allowed to enter an air box furnished with an automatically acting flap or lid, and
thence through the riser of the seat of the closet to an exit pipe provided with a
valve, substantially as herein-before described and set forth.
In witness whereof, I, the said David Gill, have hereunto set my hand and
seal, this Fifteenth day of February, in the year of our Lord One thousand
eight hundred and seventy-eight.
DAVID GILL. (L.S.)
