IMPROVE- MENTS IN CLOSET PANS AND SEATS
Year: 1885

page_text: I, THOMAS BENJAMIN WELLER of Eastgate Street, Lewes, in the County of
Sussex, Plumber do hereby declare the nature of my said invention for " IMPROVE-
MENTS IN CLOSET PANS AND SEATS" to be as follows:- i
This invention has for its object the ventilation of a closet pan in such manner
as to effectually prevent the gases and effluvia arising from the contents thereof
while the same is.in use, from escaping, through the space between the top edge of
the pan and the underside of the seat, into the house, and thus becoming a
nuisance and source of danger to the occupants.
My invention consists in the following arrangements: I form in the upper part
of the closet pan either solid therewith, or connected thereto in any suitable
manner, a nozzle or branch opening into the interior of the said pan above the
water line, and on to the outer end thereof I attach a ventilating pipe which may
be carried in any convenient manner to the outer air and be preferably provided
with a ventilating cowl or other device for causing a current of air to ascend from
the pan to the outer air. On the top edge of the pan and preferably in a recess
formed therein, I place a ring or rings of India rubber or other suitable material so
arranged as to form an airtight packing between the top edge of the pan and the
ünderside of the seat and thus prevent the admission of foul gases or effluvia into
the space under such seat and thence into the house.
Or instead of a packing ring I employ a ring or cylinder fixed to the underside
of the seat and arranged to dip into a recess on the top edge of the pan which
recess may be filled with sand or liquid in order to form a more or less gas and
airtight joint.

page_text: I, THOMAS BENJAMIN WELLER, of Eastgate Street, Lewes, in the County of
Sussex, Plumber, do hereby declare the nature of the said invention, and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement, reference being had to the accompanying sheet
of drawings, and to the letters and figures marked thereon:-
This invention has for its object the ventilation of a closet pan in such manner
as to effectually prevent the gases and effluvia arising from the contents thereof,
while the same is in use, from escaping through the space between the top edge
of the pan and the underside of the seat, into the house, and thus becoming a
nuisance and source of danger to the occupants.
My invention consists in the following arrangements. I form in the upper part
of the closet-pan either solid therewith, or connected thereto in any suitable
manner, a nozzle or branch, opening into the interior of the said pan above the
water line, and on the outer end thereof I attach a ventilating pipe which may be
carried in any convenient manner to the outer air and be preferably provided with
a ventilating cowl or other device for causing a current of air to ascend from the
pan to the outer air. On the top edge of the pan, and preferably in a recess
formed therein, I place a ring, or rings, of india-rubber, or other suitable material,
so arranged as to form an air-tight packing between the top edge of the pan and
the underside of the seat, and thus prevent the admission of foul gases or effluvia
into the space under such seat and thence into the house.
Figure 1 of the accompanying Drawing represents in vertical section a closet
pan and portion of seat with my invention applied thereto. A is the pan which
may be of any of the well-known shapes or designs with the usual overflow B, C is
a nozzle or branch for the attachment of a ventilating pipe and cowl as before
described, D is a ring of india-rubber or other suitable material preferably recessed
into the top of the pan A as shown, forming an air-tight packing between the pan
and the underside of the seat E, thus effectually preventing the escape of foul
gases or effluvia from the pan except through the ventilating nozzle C,
Figure 2 shows a modification of the section of the air-tight packing.
Instead of a packing ring, I sometimes employ a ring or cylinder fixed to the
underside of the seat and arranged to dip into a recess on the top edge of the pan
which recess may be filled with sand or liquid in order to form a more or less gas
and airtight joint or lute.
Figure 3 illustrates this modification of my invention. A is the pan with the
recess A¹ containing sand or liquid into which dips the ring F which is secured to
the underside of the seat E.

page_text: 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
In closet pans and seats the employment of a more or less air tight packing,
jointing, or lute between the top edge of the pan and the underside of the seat in
combination with a ventilating pipe, substantially as hereinbefore described, and
illustrated in the Drawings hereto annexed, and for the purpose specified.
