IMPROVEMENTS IN WATER CLOSETS
Year: 1884

page_text: I, RICHARD WEAVER of 24 High Holborn in the County of Middlesex Civil
Engineer do hereby declare the nature of my Invention for IMPROVEMENTS IN
WATER CLOSETS to be as follows:-
My improvements in Water closets mainly consist 1st in so constructing the basin
that the flush is controlled and guided so as to give the best effect and ensure
thorough cleansing of the basin-The basin is; above the outlet formed with a lip
or projection and then sloping inwards in straight or curved form to the outlet,
thus the flush in striking against this sloping or curved part effectually cleanses
the basin.
The second part of my invention is adapted for ordinary closets.
To the lower part a pan or tray is applied which closes the opening of bottom of
basin This tray on being actuated by lever or handle falls and contents of basin
are discharged into the trap direct and not through a container as heretofore The
trap can be adjusted to any position in the direction of the outgo by means of bolted
flanges.

RICHARD WEAVER 24 High Holborn Middlesex Civil Engineer I do hereby
declare the nature of my invention for IMPROVEMENTS IN WATER CLOSETS and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement consist essentially as follows :-
1st In so constructing the rim of the Basin that the water flush is controlled &
guided by contracting the rim opening at that part of the basin receiving the
arm, & gradually widening the said rim opening until the side of Basin opposite to
the arm is reached where the maximum width of opening is attained. The two
'currents there meeting are shot forward into the Closet Basin with a cuscarlo or
waterfall action & ensures thorough cleansing to the Basin & trap & sides of the
Basin. The Basin is immediately above the outlet formed with a deflector or lip
brought down vertically or nearly vertically from rim of Basin, thence sloping
inwards in a straight or curved form towards the outlet, as at a Fig 1.
When the
Busin is charged with water this lip forms the dip or water seal of the closet, & the
Baid trap may be ventilated or not. :
The Flush, whether striking against the sloping or curved part or not, is
effectively guided & directed by the form of lip towards the outlet whereby the
closet basin & trap are properly cleansed at each discharge, see Fig 1.
For certain positions & for some purposes whore greater securety against entrance
of deleterious gases & organic vapors & germinous matters thro' the water seal of
trap by back pressure, or by conduction thro' the water seal of trap after saturation
of the water, is needful, I provide a second trap below the trap of Basin with an
air-space between the two traps. This supplementary trap inay be connected to
upper trap by a bolted flange joint or otherwise so as to permit the discharge end
to deliver in any required direction. This intervening air-space separating the two
trap waters may be ventilated in either of two ways, viz:-A, by attaching a tube
to the upper end of air-space carried to outside of Building & protected by a self-
acting valve or not, whereby the enclosed air is discharged externally whenevor the
closet is in action; & when out of action by mingling with the outer atmosphere
thro' the opening of the tube provided for the purpose, see b, Fig 2.
B, by providing a secondary tube in the air-space above referred to connected
with the outer air thro' external wall of Building, to act as a fresh-air inlet to the
intermediate space enclosed between the two Traps, & in conjunction with the first
tube (without the valve in this case), that is to be carried to a suitable elovation &
capped with an extractor ventilator or not, to act as the efflux ventilator, & thus
maintain at all times whether the closet apparatus be in active operation or not, a
constant current of fresh air thro' the air-division separating the two traps, &
thereby preventing stagnation of air & avoiding accumulation of deleterious gases,
organic bases & microbes or their ova.
By these modes of ventilation the usual uprush of foul air from the closet interior
is avoided & the air-discharges are thro' the vents into the outer atmosphere & not
into the Building as commonly occurs, see Fig. 2.

page_text: The 2nd part of my invention is applicable to the closet described in the first
portion of this specification & is also adapted for ordinary water closets: To the
lower part a Pan or Tray is applied which closes the opening at bottom of Basin.
This Tray being actuated by a Lever or Handle, or by the weight of accumulated
water within the tray independently of any handle, falls, & the contents of Basin
are discharged into the Trap direct & not thro' a container as heretofore.
The Trap can be adjusted to any position towards the direction of outgo, by
means of bolted flanges or other suitable appliance; whilst the ventilation of enclosed
space formed between the upper trap of Pan or Tray (caused by the lower edge
of Basin dipping into the Pan water), & the lower Trap is effected by either of the
modes devised for the first part of this invention & hereinbefore specified, see
Fig 3.
For the construction of these water closets & traps & of their parts I use metal,
earthenware, stoneware, & other suitable materials, customarily employed in such
apparatus.
Having now particularly described & ascertained the nature of my said
invention & in what manner the same is to be performed I declare that what
I claim is
The said invention of improvements in water closets whereby the arrangement
of the flush rim is that the bulk of water is gathered in the front portion of rim &
falls with cascade effect upon the surface of Basin water: also by the shape &
configuration of back part of Basin dropping vertically or with backward slant
into the water forming a trap, & aiding the cascade action to more thoroughly
cleanse & remove contents of closet, substantially as hereinbefore set forth &
described & illustrated by the accompanying drawings.
