Improvements in Water-closets.
I, THOMAS WILLIAM TWYFORD of Hanley in the County of Stafford, Manufac-
turing Sanitary Potter, do hereby declare the nature of this invention to be
as follows:-
This invention relates to flushing rim and other closets, and consists 1st in making
the spreader out of, or in one piece with, the rim-2ndly in the formation or shape
of the open mouth or top of the basin.
Heretofore, the spreaders, or what are commonly called the fans, which are situated
at the back of the basin, and in connection with the rim opposite the flushing neck,
are made separate, and stuck on by means commonly known to potters.
Spreaders when thus made separate, and stuck on, extend forwardly into the basin,
which consequently often comes in the way of the soil, and is only obviated by
making the said pan of the closet larger.
By my invention, I make the spreader or the fan, in the form of a depending lip,
moulded with, and forming a hanging extension of the rim at the rear of the basin,
opposite the flush neck or arm, which is partially throttled at its exit, by a pierced
wall, extending upwards to above the lower boundary edge of the spreader, in such a
manner, that the flush is directed to its inside back part, and around the inside of the
hollow rim.
The junction of the hollow rim with the spreader, is slightly choked or gathered.
in, so that the water shall be distributed mainly from the spreader, instead of from
the rim.
That part of the rim which forms the spreader, is chamfered downwards from back
boundary edge of same to the lip, whilst the rim, and the open mouth of the pan, is
made pear shaped, of which the enlarged part is at back, and the gathered in part
at front, whereby the internal capacity of the pan is much lessened, and compactness
secured.
By thus making the front of the open mouth gathered-in, and curving itself to the
back and enlarged part, less flushing power is required to remove the soil.
This invention is applicable to pedestal closets, with flushing arm, vent, and S
or P traps, or to ordinary closet pans.
Dated this Twenty-second day of December 1888.

COMPLETE SPECIFICATION.
Improvements in Water-closets.
I, THOMAS WILLIAM TWYFORD of 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 :-
--
This invention relates to flushing rim and other closets, and consists 1st, in making
the spreader and rim in one piece-2ndly, in the formation or shape of the open mouth
or top of the basin.
Heretofore, the spreaders, or what are commonly called the fans, are usually made
separate from the rim, and subsequently stuck on, by means commonly known to
nottore

page_text: "
Attached spreaders extend more or less forwardly into the basin, and in consequence
of which, soil oftentimes comes in contact with them, which is undesirable.
To obviate this defect, the pans have to be made full-large, which takes more flushing
power than is desirable, to cleanse them.
By my invention, I make the spreader or the fan, in the form of a depending lip,
moulded with, and forming a hanging and rear extension of the rim, opposite the
flushing arm or neck.
The junction of spreader with rim, is partially choked in manner, that the flush
proceeding from the arm, is directed to, and around the inside of the hollow rim, and
through the spreader.
That part of the rim which forms the spreader, is chamfered downwards from back
boundary edge of same to the lip, whilst the rim, and the open mouth of the pan,
is made pear-shaped, of which the enlarged part is at back, and the gathered-in part
at front, whereby the internal capacity of the pan is much lessened, and compactness
in construction secured.
By thus making the front of the open mouth gathered-in, and curving itself to the
back and enlarged part, less flushing power is required to remove the soil.
Figure 1 of the accompanying drawings, represents partly in longitudinal vertical
section, and partly in elevation, a water closet, provided with improvements, made
according to my invention; it will be seen that both the flushing rim and spreader,
are made in common one with another, or moulded in one piece.
Figure 2 represents a top side plan of the same, showing the conformation or
construction of the said top side.
Figure 3 shows a part vertical section through A B figure 1-Figure 4 a top
side plan, partly in horizontal section, (upon dotted lines CD) showing the spreader,
and the flushing rim contiguous to it, also the partial choking between rim, and
spreader.
Figure 5 shows an underside view of the said combined flushing rim and spreader,
taken on the dotted lines E F figure 1.
Figure 6 represents a section of the rim and spreader, separately, and figure 7 the
hasin of the said closet, before the combined rim and spreadler is stuck on.
By forming the spreader as described, it is made to stand back, which is unattainable
in closets with the spreader made separate, and stuck on.
The same letters of reference indicate corresponding parts in the several figures
of the drawings.
a is the body walls of the closet, the basin, c the trap, d the ventilator, e the down
or soil pipe, leading from the trap, f the arm, or flushing inlet, g the flushing rim,
and h, the spreader made with it.
The flushing rim, which forms the top to the basin or closet, is contracted or
gathered-in at its front, which with the back part, makes a top, of the configuration
or shape of a pear, whereby the basin's cubical capacity is lessened, and flushing power
to cleanse it, greatly diminished.
The bevelling downwards of the rim.above the spreader, is marked 92, and the
partial choking or gathering-in of the said rim, at its junction with the spreader, is
marked g³, and it will be observed, that sufficient space is left between the said
gathered-in parts, for water to pass to the rim," whose inverted channel, is
marked g'.
My invention is not only applicable to closet pans as represented, but also to other
forms of closets, other than of the pedestal type.
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 :-
First Making or forming the spreader and flushing rim, of a water closet, or
water closet-pan, in one piece, substantially as described and set forth.
Secondly Forming the spreader or fan, of a water closet, or water-closet pan,

page_text: by contracting, or partially choking at points contiguous to the inlet, the back of the
said rim, substantially as described and set forth.
Thirdly Making the open mouth and basin, or the top alone, of a water-closet,
or water closet basin, of the construction and configuration, as described and set
forth, whereby the inside capacity of the pan or basin, is lessened, and more efficient
flushing secured.
Fourthly The construction of water closets, and water closet pans, as described
and set forth.
