PROVISIONAL SPECIFICATION.
Improvements in Water and Waste Water Closets and Fittings
connected therewith.
SAMUEL HENRY ADAMS, Sanitary Engineer, 7, Old Queen Street, Westminster,
London, S. W., do hereby declare the nature of this invention to be as follows:-
My improvements relate more especially to closets flushed by slop or waste
water, they are however equally good in fact and use where clean water is en-
ployed. In one form I prefer to construct my closet pan with a groove or
channel down its centre in order that whilst the closet may have a good water
area the full force of the flush will be directed through this central channel
into which heavier matter will have settled and from which such matter will
be forced by the flush directly into the outgo trap or I may use a series of such
channels or flutes converging towards the outgo trap. I prefer to form the outlet
of my closet-pan in such a way that its mouth shall partly overhang the con-
tents of closet in order that such contents shall be driven directly under and
through the trap as through a funnel mouth. In one form I prefer to discharge
my flush pipe at the floor level of pan rather than as ordinarily at the top and
to so contract the outlet through which the liquid used for flushing passes to
the pan that it shall be unable to pass out at the same rate at which it enters
the delivery pipe with the result that liquid will stand back in the delivery pipe
or drain and the discharge from the orifice will be intensified in power in pro-
portion to the head or pressure so formed in the delivery pipe. Thus I may form
my delivery pipe of say 3" or 4" or of any desired diameter reducing its outlet
to 2" or 3" diameter respectively or as desired provided my object is brought
about of piling up liquid in such delivery pipe. Such a delivery pipe is equally
useful when in conjunction with an ordinary water closet and overhead cistern.
My closets may be connected up direct to a yard trap or sink outlet drain being
flushed by such liquid as will pass down, or I may first collect such liquid in a
flushing tank discharging it there from in bulk by this means. In such a case
I prefer to use a flush tank of rectangular form and to construct the syphon
as an integral part thereof such syphon by preference having a rising leg of
rectangular form with an opening for inspection or cleansing out at its sum-
mit. The flush tank may serve also when fitted with slop stone and grating as
a yard trap.

I, SAMUEL HENRY ADAMS, Sanitary Engineer, 7, Old Queen Street, London,
S.W., 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:-
at
My proposals are seen clearly by the accompanying drawings. Fig. 1 shews
A a sink at B a flushing tank carried above the ground hav-
ing syphon outlet C and inspection ]) on syphon, the discharge
from the flush tank is shewn through the gully grate E and so through the
drain to drain I, to my special connection G and thence through the reduced
nozzle at H to closet J having the central channel K with the outlet of closet L
and funnel mouth N, at M I shew dotted a drain leading direct into H without
the connection G. At Fig. 2 I shew a plan of the closet and the special con-
nection G it will be seen that the diameter of this connection is greater than that
of the contracted nozzle at H and by this means when a quantity of water is
discharged from the vessel B because it cannot pass as quickly through Hit
rises up in G and so I obtain a head of water for a longer period than would be
the case without this reduced nozzle and hence a longer continued flush to the
closet Under the sink A I shew a syphon flusher but it is evident that a tipping
bucket or other arrangement would serve my purpose for collecting liquid direct
from the sink and discharging it to a closet.
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:-
1st The use of a waste water closet wherein the feed pipe supplying
liquid to the same shall be so contracted at or near its connection to the closet
that it momentarily holds back the flushing liquid in the pipe and by reason
of this head of liquid more efficiently flushes the closet.
2nd The use of a waste water closet having an invert or channel as described
to direct the flush.
3rd The use of a trumpet mouth outlet in a waste water closet in combination
with the feed pipe having a reduced diameter outlet as described.
4th The use of a flushing cistern raised from the ground and placed under a
sink whether fitted with a syphon or other mode of discharging the liquid and
whether used with a closet or not.
5th The use of the appliances shewn and described or their equivalent though
differing in conformity substantially the same.
Dated this 13th day of April 1900.
