I, HARRY WEYTE BUCHAN of 15 Spottiswoode Street, Edinburgh, in the County
of Mid Lothian, Clerk, do hereby declare the nature of this Invention to be as
follows:-
This Invention relates to improvements in water closets wherein a plug valve is
employed to open and shut off communication between the closet basin and the soil
pipe and it has for its object to provide a water slide and seal for the spindles of such
valves whereby the escape of gas is prevented at the orifice in the seat or cover
through which the valve rod or spindle passes and also whereby the rod has greater
freedom of action than when a stuffing box is used for the like purpose.
In carrying out my Invention I fix a downwardly projecting tube to the cover of
the closet and so as to surround or enclose the orifice in the cover through which the
valve rod works. An upwardly projecting tube is fixed to the upper side of the valve
the upper tube telescoping into the lower one which is filled or partially filled with
water and constitutes a water seal. The rod for working the valve projects down
through both tubes and when the valve is raised the lower tube slides upwards on the
upper one the water seal preventing the escape of gas at the orifice in the cover
through which the valve rod passes.

page_text: 1, HARRY WHYTE BUCHAN, of 15 Spottiswoode Street, Edinburgh, in the County of
Mid Lothian, Clerk 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 improvements in water closets wherein a plug valve is
employed to open and shut off communication between the closet basin and the soil
pipe and it has for its object to provide a water slide and seal for the spindles of such
valves whereby the escape of gas is prevented at the orifice in the seat or cover
through which the valve rod or spindle passes and also whereby the rod has greater
freedom of action than when a stuffing box is used for the like purpose.
In the accompanying drawings figure 1 is a vertical section of a water closet
showing my invention applied thereto and figure 2 is a vertical section showing
separately the water slide constituting the invention and which consists of a down-
wardly projecting tube A, fixed to the cover B, of the closet or of the valve chamber C,
thereof, said tube being fitted so as to surround or enclose the orifice in the cover
through which the valve rod D, works. An upwardly projecting tube E, is fixed to
the upper side of the valve F, the upper tube A, telescoping into the lower one E
which is filled or partially filled with water from the valve chamber or otherwise and
constitutes a water seal. The rod D, for working the valve projects down through
both tubes and is secured to a washer fixed on the under side of the flexible valve F,
and when the valve is raised the lower tube E slides upwards on the upper one A the
water seal preventing the escape, at the orifice in the cover B, through which the
valve rod passes, of gas which may enter the valve chamber from the soil pipe. A
cup G is fitted on the cover B, around the valve rod to prevent overflow of water
which may be carried through the tube A, on raising the valve.
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 conjunction with a plug valve for a water closet the telescoping tubes A, E,
arranged and combined to constitute a water slide or seal substantially as herein
described.
