Improvements in Noiseless Water Closets, and Apparatus connected
therewith.
I, HENRY SUTCLIFFE, of the Firm of Wright Sutcliffe & Son, Brassfounders and
Sanitary Engineers, Adelaide Street, Halifax, in the County of York, do hereby
declare the nature of this invention to be as follows:-
This invention relates to improvements in noiseless water closets and apparatus
for flushing the same. The improvements consist of employing a flushing cistern
with a syphon of a large bore in combination with a closet basin preferably similar
to that described in my Specification No. 2479 of Feby, 4th 1893, or with any other
closet basin if constructed with a flushing rim of sufficient water capacity and with
an inlet sufficiently large to receive a special mouthpiece which is screwed on to
the bottom of the long leg of the syphon at one end, the other end being attached
in a suitable manner to the inlet of the closet basin. The syphon is started by.
means of a plunger operated by a hand lever which is practically noiseless in action.
I also provide a separate vessel or chamber in the cistern to give an after flush in
order to prevent unsealing of the water trap in the closet basin in case of syphonage.
In order that the apparatus may also be used as a urinal the closet seat is fixed
to the front part of the cistern box by means of a special form of hinge. The
whole contrivance has been designed so as to be noiseless in action, easily and
efficiently flushed, and to occupy a minimum amount of space when fixed.

COMPLETE SPECIFICATION.
Improvements in Noiseless Water Closets, and Apparatus connected
therew.th.
I, HENRY SUTCLIFFE, of the Firm of Wright Sutcliffe & Son, Brassfounders and
Sanitary Engineers, Adelaide Street, Halifax, in the County of York, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following state-
ment;
The object of my said invention is to improve the cleansing action of the water
used in water-closets by means of improved construction. The apparatus as made
with my improvements is shown on the accompanying sheet of explanatory
drawings

page_text: Figure 1, Sheet 1, is a sectional drawing showing in combination a syphon
cistern, closet basin, also connection between the said cistern and basin. A is
the cistern, B is the syphon the internal bore of which I prefer to be 2½ inches.
Cis the plunger for starting the syphonic action. D) is the lever for operating the
plunger. E is the outlet from cistern with a long threaded connection upon which
is a locknut K having lugs F by means of which the locknut K is screwed down
and the rubber washer G compressed into the inlet socket of closet basin H thus
ensuring a complete and perfect joint and doing away with the usual putty and
paint joint. I is a wooden casement screwed on to the cistern A by means of
screws J for supporting the said cistern in proper position. The operation is as
follows: On pushing forward the hand-lever D the plunger C reciprocates in
the charge chamber L and forces the water over the crown of the syphon B thereby
starting syphonic action. I make no claim for the starting device.
This combination of parts forms a complete water-closet apparatus which is
practically silent in action and which ensures a most efficient cleansing action of
the water every time the apparatus is used.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what I
claim is:-
Firstly. The improved combination of parts constituting the water-closet appar-
atus as described and illustrated by the accompanying sheet of drawings.
Secondly. The combination of the water-closet apparatus with the connection E,
locknut K, lugs F, and indiarubber ring G, for making the connection to closet
basin H, substantially as and for the purposes hereinbefore described.
Thirdly. In connection with the water-closet apparatus the wooden casement I
fixed to cistern A by means of screws J, substantially as and for the purposes
herein before described.
