PROVISIONAL SPECIFICATION.
Improvements in the Construction of Water Closets.
I WILLIAM HODGSON, of 53 Spring Street, Hull, in the County of York,
Plumber do hereby declare the nature of this invention, to be as follows:-
The object of my invention is to provide a larger area of water surface in the
basin of water closets for the reception and deodorization of the excreta, at the
same time with only a small surface of basin exposed to be fouled by the said
excreta and a deep seal of water in the trap.
I construct my water closet with the flushing arm and ring exactly opposite the
exit or outlet, and formed so that the strength of the flush thoroughly scours
the basin and trap (at a great velocity) effectually cleansing all parts of same,
and passing through the trap both solid and light material such as paper and
the like.
The side of the basin forming top of trap opposite the flush, projects at an angle
or inclined plane of about 45 degrees, almost to the centre of the said basin.
measuring from the top of the trap on the water line.
The basin into which the excreta drops is formed of a small semicircle shape at
the bottom and continues upwards at the same angle as before described, forming the
bottom sides of the trap, then downwards at a similar angle to the trap outlet,
thereby attaining the above desirable results; also the drop of the excreta to the
waterline is very short.
Dated this Twenty-eighth day of August 1894.

Improvements in the Construction of Water Closets.
I WILLIAM HODGSON, of 53 Spring Street, Hull in the County of York,
Plumber, 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 :-
The object of my invention is to provide a large water area in the basius of
water closets for the reception and deodorization of the excreta, at the same time
with only a small surface of the basin exposed to be fouled by the said excreta, and
a deep seal of water in the trap.

Fig. 4 shows sectional view of spreader and flushing arm fixed to basin.
construct my water closet with the flushing arm A. exactly opposite the exit
or outlet B and formed so that the strength of the flush thoroughly scours the
basin C and the trap D effectually cleansing all parts of same and passing through
the trap both solid and light materials such as paper and the like.
The side of the basin forming the top of the trap opposite the flush projects at
an angle or inclined plane of about 45 degrees almost to the centre of the said
basin, then downwards at a similar angle E to the trap outlet F, thereby attaining
the above desirable results; also the drop of the excreta to the water-line is
very short.
The aforesaid inlet arm A for distributing the flushing water (from a cistern or
other available water supply) I make of metal or other suitable material, and is
secured to the sides of the basin C in front of the mouth of the water delivery pipe
by bolts G and washers H and is fitted with a copper or the like spreader J¹
attached to the inside of the basin which will thoroughly flush and cleanse both the
basin C and the trap D, and in conjunction with the said arm A. I employ a
conical joint K which forms part of the flushing arm A, this will render the water
closet practically frost-proof, and will enable such closets to be made with similar
flushing capacity for fixing in groups or ranges, which hitherto has been very
difficult to accomplish in earthenware on account of the goods warping in the
kilns whilst being fired.
The said basin C may be also made with the flushing or inlet arm A plain and
in one piece with the basin, as shown at Fig. 2, and with flushing rim L as shown,
also with either S or P traps (the trap being shown in full lines and the P trap
in dotted lines, and with any suitable means of connection to soil pipes as required
to meet the regulations of county councils or other public bodies, also the basin and
trap may be made separately.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. Constructing water closets with elevated water level so ensuring increased
water area and depth, the outgo or exit being an inclined plane for facilitating the
expulsion of all matter therefrom, and with improved flushing arm and spreader
with conical joint, as and for the purposes substantially as shown and described.
2. Constructing water closets with elevated water level so ensuring increased
water level and depth, the outgo or exit being an inclined plane for facilitating the
expulsion of matter therefrom as and for the purposes substantially as shown and
described.
