Closet Pans.
I, JAMES GEORGE STIDDER, of 50 Southwark Bridge Road, in the County of
Surrey, Sanitary Engineer, do hereby declare the nature my said invention to be
as follows:-
The object of my invention is to construct water closet pans in such a manner
that the flushing of the same may be more effectually performed than hitherto.
In carrying out my invention I fit or otherwise attach or form at the back of
the water closet pan, or in any other position suitable for flushing the same,-a
flushing fan on which are formed three or more lips, which project into the pan at
different angles; the central lip I make to project at a greater angle than the other
lips, which are more vertical so as to force away all matter from the sides of the
pan and out into the trap at the first flush of water.
The operation is therefore as follows:―
The water on reaching the fan, is formed by it into a number of jets each jet
advancing in a different direction, so as to reach every part of the pan, and the
central jet of water, which is thrown to a greater distance than the other jets,
drives all matter immediately out of the pan into the trap or drain and the pan
becomes thoroughly and effectually cleansed.

COMPLETE SPECIFICATION,
Improvements in the Method and Means of Flushing Water
Closet Pans.
I, JAMES GEORGE STIDDER,, of 50 Southwark Bridge Road, in the County of
Surrey, Sanitary Engineer, do hereby declare the nature of my said invention and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
The object of my invention is to construct water closet pans in such a manner
that the flushing of the same may be more effectually performed than hitherto.

page_text: In carrying out my invention I fit or otherwise attach or form at the back of
the water closet pan, or in any other position suitable for flushing the same, a
flushing fan on or in which are formed three or more lips, which project into the
pan at different angles; the central lip I make to project at a greater angle than
the other lips, which are more vertical, so as effectually to wash away all matter
from the sides of the pan, and drive it out into the trap at the first flush of
water.
The operation is therefore as follows:-
The water on reaching the fan, is formed thereby into a number of jets, each jet
advancing in a different direction, so as to reach every part of the pan, and the
central jet of water, which is thrown to a greater distance than the other jets,
drives all matter immediately out of the pan into the trap or drain, and the pan
becomes thoroughly and effectually cleansed.
And in order that my said invention may be particularly described and ascertained,
reference is hereby made to the accompanying drawings, in which similar letters of
reference indicate corresponding parts.
Fig. 1 is an elevation of my improved flushing fan, and Fig. 2 shews the same
in perspective fitted to a pan, with lines f f indicating the direction of the streams
of water.
a is the improved fan, b is the central lip, which projects at a greater angle than
the two side lips c c. There is also a limited space under the two ends at d d for
the passage of a thin film of water, as shown in Fig. 2. e is the flushing pipe
which conveys water to the fan.
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 :-
:-
1. The method of flushing water closet pans substantially as hereinbefore
described and shewn on the drawings.
2. The use and application of my improved fan or flushing appliance, to water
closet pans, constructed arranged and operating substantially as and for the
purposes hereinbefore described and shewn on the drawings.
