JOSEPII FARRIMOND of Southport in the county of Lancaster, Builder, and
JAMES WHITTAKER of the same place Plumber IMPROVEMENTS IN VENTILATING
WATER AND OTHER CLOSETS
"
The object is to provide water, earth, pail and other closets with ventilating
appliances so constructed and arranged that any disagreeable or noxious gas smell
or effluvia shall be carried away and effectually prevented from entering the
dwelling house or apartment containing such closet.
In carrying our invention Into practice First. We construct out take or upcast
ventilating shafts or pipes for connection to closets in any usual or desired mauner,
with coats; coverings, or linings of such a naturo and so disposed as to maintain a
temperature adapted to cause suction to take place through the said shafts or pipes
and ensure the passage of the noxious gases therethrough.
Second. In connecting ventilating pipes or shafts under the first part to the pan
or basin of the closet in such manner that any noxious or objectionable gas odour
or effluvia shall be removed from the said pan or basin as fast as it is generated.
Third. In combining with the first and second parts an air inlet way or ways so
arranged as to provide a steady inflow of pure air into the closet pan or basin so
as to carry the undesirable gases into the ventilating shaft or pipe:

page_text: Fig 1 is a plan and fig 2 a vertical section of a water closet provided with our
improvements, a pan or basin, b trap and soil pipe, c seat, d foul air receiver inter- 2
posed between the seat c and pan or basin a. e packing, way or passage leading
from the foul air receiver d to the suction pipe g, jacket surrounding the pipe g.
The space between the pipe and jacket is filled with non conducting material as
regards heat in order that the said pipe may he maintained at a nearly uniform
temperaturo, i closet lid, j valve in the way or passage f for regulating the outflow 3
of air, pipe opening to soil pipe below the trap b. The dotted lines / show an
inlet way to allow of the passage of air over the pan or basin a when the lid is
closed.
It will be obvious that the receiver e may if desired be part of the pan or basin
though it is preferable to make it detachable therefrom. The pipes or ways fa
and g are of any suitable metal or material and are made in lengths to suit
requirements.
Having now described and illustrated our said invention in such manner that
others will be enabled to carry our improvements into effect, We claim:―
First. The improvements in ventilating water closets 'substantially as herein
setforth.
Second. The combination of a suction pipe g, jacket % and way or passage f
leading to the space to be ventilated.

page_text: Third: The combination of the pan or basin ȧ, foul air receiver d, way or
passage and suction pipe g.
Fourth. The combination with ventilating appliances constructed arranged and
operating substantially as hereinbefore set forth of an inlet way l.
In Witness Whereof I the said Joseph Farrimond have hereunto set_my_hand
and seal this twenty seventh day of December in the year of Our Lord, one
thousand eight hundred and eighty three.
