A New and Improved Flushing Valve and Water Closet
Attachment.
I, NIMROD SIMMONS B.Sc. of. 8 Glendale Clifton, in the City and County of
Bristol,. Civil Engineer, 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 :-
A New and Improved Flushing Valve and Water Closet Attachment which can
be connected to any ordinary water closet at the outlet from the trap, and thereby
converts the closet into a valve closet which can be cut off.from connection with the
drains at will.
The valve has a circular and perfectly clear: bore without camber or dip, which
would be likely to induce the lodgment of solid matters; and can be operated by
means of an ordinary pull and chain, or by means of a hand wheel.
The valve may be checked open and the closet flushed directly from the flushing
water tank if desired for any reason, or if the valve mechanism should at any time
become temporarily deranged, the closet can be used without difficulty, as it is then
in the condition of an ordinary pan and trap closet.
If reference be had to the accompanying drawings, Fig. 1 is a section through
any closet, and through the valve chamber A connected. B is a disc valve of
circular form; and provided with a jointing ring of india-rubber or similar elastic
material at b, hinged movably on the spindle. C, which is journalled in an extension
from the chamber cover c..
The valve closes against a circular seating formed in the chamber.
The spindle C is carried through the side of the chamber, movably as regards
rotation on its axis; and a lever G is conuected rigidly to it outside the chamber.
A link or links F connect the lever with a lifting rod E movably, and the rod E is
continued downward and provided at its lower end with a piston I working in an
air or buffer cylinder H which is fitted with a regulating cock J. The rod E is
also connected to a compensating spring K through the arm L so that the spring is
constrained to keep the rod and piston in their lowest and normal position.
Fig. 1 interprets the valve as closed, and keeping the pan full of water or at
overflow level; and the water is discharged by operating the pull D connected by
chain over leaders to the lifting rod E,-and between D and E to the flushing
water tank and link or links F, and lever G, thereby opening the valve.
The lifting of the rod E, piston I and arm L causes the cylinder H to become
filled with air through the cock J, or by a separate valve or orifice; and the
tension of the spring K when extended, compensates for the upward motion and
expels the air (as the valve closes) from the cock J, which can be regulated to time
the closing of the valve to a great nicety. This regulation prevents the escape of
too much clean water which follows into the basin and trap after each discharge.
The pan and trap is thus always filled with clean water, and cut off from the
drains.
Fig. 2 is an enlarged view of the lifting rod E, link or links F, lever G, air
cylinder H, piston I, regulating cock J, compensating spring K, and arm L.
Fig. 3 is a section similar to Fig. 1, but shows the valve operated alternatively
by a handwheel D, spindle E, journalled in a boss F, on the cover c. A worm G,
engaging with and operating a quadrant rack H, connected to or formed upon the
valve B, which is hinged movably at C upon a spindle journalled in an extension
from the cover c of the valve chamber.

page_text: The closet is here shown discharged, and in a condition general to all ordinary
water closets, as regards water seal.
The valve may be closed every time the closet is used, or it may generally be left
open, and periodically closed to fill the basin, or cut off communication with the
drains.
The valve in either form. may be connected to the flushing water tank in such
manner that both are operated simultaneously, or not, as may be desired; and the
valve may be placed in the line of piping at any distance from the closet as may be
convenient.
The valve may also be placed at the end of a system of drain or soil pipes
connected with water closets, and by this means the system of pipes can be filled
with clean water for cleansing purposes, or to form an effective flush when discharged
into the drains and sewer.
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.-
1. The combination of a valve chamber as described with a clear. and full bore
without obstruction, a disc valve hinged movably as described and operated by
means of rods, and links, and lever, as described or with hand wheel, spindle, and
worm and quadrant rack; also as described and with the mechanism inside the
chamber attached to the cover and removably, with the same.
2. The combination of parts named and shown and with the disc valve shutting
down upon a circular seating formed in the valve chamber, and closing watertight
by means of a packing ring of india-rubber or other elastic substance as shown.
3. I claim also for the air chamber H, the expelling piston I, and regulating
cock J together with the combination of rod E, link or links F, and lever G, for
operating the valve, and the compensating spring K, connected and for the purpose
of closing the valve automatically after discharge.
4. I claim for the combination of a flushing valve as described, and also in
combination with any pan and trap to form a valve closet, and I further claim for
the valve used at any distance from the closet upon a system of pipes to fill the
same for flushing and cleansing purposes.
