An Improved Waste Water Closet Pan.
I, WILLIAM ROSTRON PICKUP, Secretary and Manager of The Turton Moor
Sanitary Pipe Co., Ld., of Darwen, in the County of Lancaster, do hereby declare
the nature of this invention to be as follows:--
This invention relates to that class of waste water closet pan which is provided
with an inlet at one side for the waste water and a curved ridge at the bottom
for causing a swirling motion of the water as it flushes the pan.
The invention consists in making the outlet eccentric in the bottom of the
pan, and at the opposite side of the said pan to the inlet (when looked at from
above or below) but close to the outlet, so that the ridge does not appreciably
reduce the width of the channel and so check the rush of flushing water into the
pan, but merely guides it round in a convolute direction to the outlet, the ridge
gradually decreasing in height until it is almost level with the bottom of the
channel leading to the outlet.
By this construction the full force of the water is utilized to flush the pan.

I, WILLIAM ROSTRON PICKUP, Secretary and Manager of The Turton Moor
Sanitary Pipe Co., Ld., of Darwen, in the County of Lancaster, 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 that class of waste water closet pan which is provided
with an inlet at one side for flushing water, and a curved ridge at the bottom for
causing a swirling motion of the water as it flushes the pan.
In the accompanying drawing Fig. 1 is a plan of a pan as herein before named
constructed according to my invention. Fig. 2 is a cross section on line A-A,

similar parts.
My invention consists in making the outlet eccentric in the bottom of the
pan and at the opposite side to the inlet c in said pan (when looked at from
above or below) but close to the aforesaid outlet. A curved ridge d is formed
between the inlet and the outlet, the said ridge gradually decreasing in height

page_text: until it is almost level with the bottom of the channel leading to the outlet. The
width of the channel is not appreciably reduced by the ridge or the rush of flush-
ing water into the pan checked thereby, but the water is guided round, in a con-
volute direction to the outlet that is eccentrically placed, and the full force of
water is by these means utilized to flush the pan.
i
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-
In a waste water closet pan the combination of an inlet for flushing water, an
outlet eccentrically placed in the bottom of, and at the opposite side of the said
pan to the inlet, and a gradually decreasing curved ridge between the inlet and
the outlet all substantially as and for the purpose hereinbefore described and as
shown on the drawings.
