PROVISIONAL SPECIFICATION.
An Improvement in the Construction of Water Closets for use in
Railway Carriages, Sailing Vessels, and the like.
I JOHN THOMAS BOLDING trading as John Bolding & Sons of "Grosvenor
Works" Davies Street London Brass Founder do hereby declare the nature of
this invention to be as follows:-
This invention has for its object an improvement in the construction of water
closets for use in railway carriages &c. and in order that my invention may be
better understood I now proceed to describe the same.
The pan and pedestal or base of the water closet are made in earthenware, metal
or any other suitable material, but preferably in copper or white metal to prevent
breakage by jarring or oscillation. This pan and pedestal or base being securely
fixed to an iron frame or standard, which can be screwed to the floor and sides of
the carriage.
The seat of the water closet is weighted at the back so that when not in use it
remains in an upright position but in shutting it down for use it opens slightly by
means of a lever & camb an improved form of supply valve fixed on an iron frame
at back and allows a small quantity of water to flow which wets the surface of the
basin and so prevents soil from adhering thereto and forms a depth of water in the
bottom of the pan which is retained by an automatic tipping valve. Immediately
on the seat being released it assumes an upright position and its progress fully
opens the regulating valve which will then discharge a given quantity of water
into the pan, this quantity of water being of greater weight than the automatic
tipping valve will sustain at the bottom of the pan, the valve falls and the whole
of the contents of the pan is then discharged through an aperture at the bottom.
Dated this First day of January 1892.

COMPLETE SPECIFICATION.
An Improvement in the Construction of Water Closets for use in
Railway Carriages, Sailing Vessels, and the like.
I, JOHN THOMAS BOLDING trading_as John Bolding & Sons of Grosvenor
Works, Davies Street, London, Brass Founder, 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 has for its object an improved construction of water-closet for use
in railway carriages on board ships, and other places, and in order that my
invention may be better understood, I now proceed to describe the same.
According to this invention, I make the pan, and pedestal or base of the water
closet of any suitable material, but I prefer to make them of metal so as to prevent
breakage by jarring or oscillation, such pan and pedestal, or base, I securely fix to
a suitable frame or standard, say of iron, capable of being fastened to the floor and
side or sides of a railway carriage or other place, for example; I weight the seat
at back so as to hold it in a vertical position when not in use, and on shutting it
down to the horizontal position, it allows a self closing supply valve to open as
hereafter described, and thus allows a certain quantity of water to flow into the
pan, so as to wet the surface of the basin and thus prevent the soil from adhering
thereto, and this also forms a depth of water to remain in the bottom of the pan
which is retained there by an automatic tipping valve.

page_text: Immediately on the seat being released it assumes an upright position, and in its
progress fully opens the regulating valve, which will then discharge a given
quantity of water into the pan, and the weight of the water opens the aforesaid
tipping valve, so as to discharge the contents of the pan; and in order that my
said invention may be fully understood, I will now describe the same with reference
to the accompanying sheet of drawings in which
Fig. 1 shows section of water closet as it would appear when in use, and Fig. 2
top plan of same.
The same letters denote the same parts in both views.
a. the pan; b. pedestal or base; c. c. counter-balance weights fitted to back of
seat; e. e. rollers mounted in bearers c. at back of seat for actuating the supply
valve f. by means of lever k. g. discharge pipe; h. tipping valve.
The action as follows ;-
Upon the seat being depressed, it causes the supply valve f to open slightly, and
thus to supply enough water to wet the pan so as to prevent soil from adhering
thereto; and when the seat arrives at the horizontal position, the said valve will
then be closed by pressure of the rollers e. e. on the lever k. and when pressure is
taken taken off the seat this latter rises to an upright position, and in so doing
releases and allows the supply valve to open and flush the pan, and the extra
weight of water coming on the tipping valve h. causes it to fall and discharge the
whole of the contents of the pan through the pipe g. either into a receptacle
placed to receive such contents, or if the closet is fitted in a railway carriage,
through the bottom of such carriage; after which the tipping valve returns to its
normal position. The weights c. c. keep the seat in an upright position.
The drawings show the water closet made to be fitted in a corner, but of course
it may be made equally well to fit anywhere..
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 water-closets for railway carriages, vessels and other places :
The seat having at the back thereof a lever to actuate an automatic closing
supply valve, when such seat is either depressed or caused to rise in an upright
position; also the tipping valve and counterbalance weights connected to the seat,
all substantially as and for the purposes set forth.
Dated this Thirtieth day of September 1892.
