COMPLETE SPECIFICATION.
Improvements relating to Closets or Privies and to Pans therefor.
I EDWARD WILLIAM CRACKNELL of Bond Street Chambers George Street in the
City of Sydney and Colony of New South Wales, Consulting Engineer and Architect
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 has been specially devised in order that the escape of noxious gases
and odours from the pans or receptacles of closets or privies may be practically.
prevented and that the pans or receptacles may be easily and quickly removed without
causing nuisance.
These improvements relating to closets or privies and to pans therefor consist first
and essentially in the combination and arrangement with a pan or receptacle in a closet
box or cupboard of a ring or washer of india rubber or other suitable (and preferably
elastic) material between the underside of the seat of said closet box and the top of
said pan or receptacle and crossed wedges or other means adapted to press said pan
upwards against said seat and to make an air-tight joint on the washer between them.
They consist secondly in the combination and arrangement with the cover of a closet
box or cupboard of a ring or dise of india rubber or other suitable (and preferably
elastic) material adapted to make an air-tight joint on the closet seat when said lid is
closed.
But in order that this invention may be clearly understood reference will now be
made to the drawings herewith in which
Figures 1, 2 and are plan elevation and section respectively of the parts of a
closet or privy necessary to show these improvements applied thereto.
Figure is a cross section of a closet pan with a cover attached thereto.
A is pan or receptacle. B washer or ring of india rubber. Ccloset scat. D closet
cover. D' rubber disc. E movable wedge. F stationary or hinged wedge. G door.
HI pan handles. J pan cover. K spring.
The pan bucket box or receptacle A may be made of metal wood earthenware or
other impervious material or of material rendered impervious by asphalt, paint, tar,
rubber, varnish or other substance. The pan A is pressed against ring or washer B
of rubber or other suitable (and preferably elastic) material by driving or pushing
wedge E on hinged wedge For by other mechanical contrivances rising the support
of the pan or the pan itself (where the available space is limited). The upper flap or
lid D with the rubber or suitable elastic disc D' thereon is pressed on the seat by
its own weight or by springs on its hinges so as to form a gas-tight joint which with
the joint formed at B effectually prevent the escape of noxious gas or air from the
closet pan or receptacle. This pan A is removed by opening the door G withdrawing
the wedge E and so releasing said pan from the ring or washer B. The pan being
drawn forward is then covered with an air-tight cover as shewn in Figure 4. The lid
is provided with rubber or elastic washer to form a gas-tight joint and is kept in its
place and pressed down by the spring K which hooks on the handle I and clips the
handle H. A clean pan being inserted through door G the wedge E is tightened as
before described and the closet is again ready for use. The door G may be placed in
front as shown or at either side or back in order to suit the requirements of the
building and where the sides are not available the receptacle may be removed by
lifting up in which case the seat C is furnished with a hinge and suitable clip or
fastening.

page_text: Having now particularly described and explained the nature of my said inven-
tion and the manner in which the same is to be performed 1 declare that what I
claim is
First The combination and arrangement with a pan or receptacle under a closet
or privy seat of a ring or washer of india rubber or other suitable (and preferably
elastic) material between said pan and said scat and crossed wedges or other mechanical
means adapted to press said pan upwards against and on said washer substantially as
herein described and explained.
Second The combination and arrangement with the cover of a closet box or
cupboard or closet seat of a ring or disc of india rubber or other suitable (and
preferably elastic) material adapted to make a gas-tight joint when said seat is closed
substantially as herein described and explained.
Third As an improvement relating to closets or privies and to pans therefor the
combination and arrangement with a seat such as C of a soft or elastic ring or washer
such as B and wedges such as E and F and the combination and arrangement with a
cover such as D with or without spring hinges of a soft or elastic ring or disc such
as D substantially as herein described and explained and as illustrated in the
drawings.
