PROVISIONAL SPECIFICATION.
Improvements in Water Closets or Water Closet Basins.
I, THOMAS WILLIAM TWYFORD, of Cliffe Vale Pottery, Hanley, in the County
of Stafford, Manufacturing Sanitary Potter, do hereby declare the nature of this
invention to be as follows:
My invention has relation to the pans or basins of wash-down water closets, and
has for one of its objects, the prevention of the fouling or soiling of the back
walls of the same, and for a further object, means for securing a larger surface of
water, in the pan or basin.
In carrying out the production of a wash-down water closet basin provided
with improvements made according to my invention, I provide the back walls of
the pan of the same, above the water line, and adjacent to the inlet to the trap,
with a cavity, depression or hollow, set back from the general plane of the said
walls, by which the superficial area of the inside of the pan, a little above the
water level, is increased, and whereby a larger surface of water to receive the soil,
is secured, whilst the back walls of the pan are thereby not liable to become
soiled or fouled.
I propose that the said cavity or depression should be concaved and the boundary
parts of it graduated into the surrounding walls of the pan, whilst the lower part
is made to lead off into the part of the basin below the water line.
Dated this 14th day of Kebruary 1894.

COMPLETE SPECIFICATION.
Improvements in Water Closets or Water Closet Basins.
I, THOMAS WILLIAM TWYFORD, of Cliffe Vale Pottery, Hanley, in the County
of Stafford, Manufacturing Sanitary Potter, 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:-
My invention bas relation to the pans or basins of water closets, particularly of
the wash-down type, and has for one of its objects, prevention of the fouling or
soiling of the back walls of the same, and for a further object, securing an
increased area of water surface in the pan or basin.
In carrying out a wash-down water closet basin provided with improvements the
back walls of the pan at about the water line, and at a part where the soil strikes
the inside walls adjacent to the inlet to the trap, are provided with a cavity,
depression or hollow, set back from the general plane of the said walls, by which
the superficial area of the inside of the pan, at and about the water line, is
increased so that besides securing a larger surface of water in the pan, the back
walls of the pan are prevented from being fouled or soiled.
1 propose that the said cavity or depression should be concaved and that
the boundary parts of it should be graduated into the surrounding walls of the
pan, and the lower part led off into the part of the basin below the water line.

page_text: Figure 1 of the accompanying drawings represents a vertical section of a water
closet of the wash-down type, provided with the aforesaid improvement.
Figure 2 is a horizontal section of the same upon the dotted lines x-x
Figure 1.
Figure 3 represents another horizontal section upon the dotted lines A
Figure 1, whilst Figure 4 represents a vertical section upon the dotted line B,
looking towards the back walls of the closet, and showing the set-back cavity
therein at and about the water line.
a is the pan or basin of the closet, having an inlet arm a¹, and a trap a³, with
other usual auxiliary adjuncts, and with the back walls a³, set back or sunken
at a, so as to form a clearance out of the general plane of the inside walls of
the pan.
I might add that in other types of closets, such as wash-out closets, a clearance
may be formed upon both the back and front of the inside walls.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
In water closets, or water closet basins or pans, providing or forming within the
inside walls of the same, at and about the water line, a cavity, depression, or
set-back part or parts, substantially as and for the purpose as described and set
forth.
