PROVISIONAL SPECIFICATION.
Improvements connected with Hot-water Cylinders.
I, EDWARD NICHOLSON BESZANT, of 91, Belgrave Road, St. Michaels,
Liverpool, Master Plumber, do hereby declare the nature of this invention to be
as follows:-
This invention has for its object to provide means whereby a hot-water cylinder
may be filled by hand whilst the ordinary feed or circulating pipes are frozen or
disconnected, thereby allowing the kitchen fire to be lighted without the danger of
an explosion.
It has hitherto been the practice when the cold water feed to the cylinder has
been frozen, to disconnect such pipe and to fill the cylinder by hand through the
aperture thereby provided. By my invention such disconnection is rendered
unnecessary.
According to this invention a device comprising a cup or funnel, provided with
a valve, is attached to or forms part of the cylinder, or the device may be attached
to the hot-water supply pipe which leads out of the top of the cylinder. The
valve is arranged to close against the pressure within the cylinder by means of a
lever provided with a weight or spring.
In order to fill the cylinder, the valve is opened by raising the lever; water is
then poured into the cup or funnel and finds its way into the cylinder through the
aperture normally closed by the valve.
It will be seen that the weighted or spring retained valve forms a safety valve
to the cylinder, and the device further provides a ready means of ascertaining
whether the cylinder is charged with water.

1, EDWARD NICHOLSON BESZANT, of 91, Belgrave Road, St. Michaels,
Liverpool, Master Plumber, 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 to provide means whereby a hot water cylinder
and kitchen boiler may be filled by hand when the ordinary feed pipe is frozen or
cut off, thereby allowing the kitchen fire to be lighted without the danger of an
explosion.
It has hitherto been the practice when the cold water feed to the cylinder has
been frozen, to disconnect the steam or hot water supply pipe and to fill the
cylinder by hand through the aperture thereby provided. By my invention such
disconnection is rendered unnecessary.

page_text: According to this invention a device comprising a cup or funnel, provided with
a valve, is attached to or forms part of the cylinder, or the device may be attached
to the hot water supply pipe which leads out of the top of the cylinder. The
valve is arranged to close against the pressure within the cylinder by means of a
lever provided with a weight or spring.
In order to fill the cylinder and boiler, the valve is opened by raising the
lever water is then poured into the cup or funnel and finds its way into the
cylinder through the aperture normally closed by the valve.
It will be seen that the weighted or spring retained valve forms a safety valve
to the cylinder and boiler, and the device further provides a ready means of
ascertaining whether they are charged with water.
In the drawing hereto annexed is illustrated a combined filling and safety valve
constructed according to this invention, Figure 1 being a sectional elevation and
Figure 2 a plan of same.
Upon reference to the drawings it will be seen that a is the filling cup, which
is closed by a valve b. c is a weighted lever, controlling the valve b. Figure 3 is
a view shewing the application of my invention, in which A is a hot water cylinder
and B a kitchen boiler.

The combined filling and safety valve is preferably fitted to a hot water cylinder
by means of a cast metal V shaped piece of pipe which is attached to the cylinder
by means of a socket collar and coupling. One branch of this ✓ piece forms the
"
steam or hot water supply pipe of the cylinder, the combined valve being
mounted upon the other branch. The valve is thus in direct communication with
the cylinder, the weighted lever being adapted to close the valve against the
pressure within the cylinder. In order to fill the cylinder and boiler with water in
the event of the usual supply being cut off by frost or otherwise, the lever c is
slightly raised in order to open the valve b, and water is then poured into the
cup a and finds its way past the valve and into the cylinder. It will be seen that
in addition to serving as a means for filling the cylinder the valve b also acts as a
safety valve and will relieve any undue pressure within the cylinder. The lever c
is preferably graduated in order that its weight may be adjusted to suit different
heads of water and consequently different pressures within the cylinder and
boiler.
As a direct means of filling a kitchen boiler the combined filling and safety
valve according to this invention may be placed upon the boiler itself, as shewn
in Figure 3, thereby also acting as a safety valve to the boiler.
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 :-
The employment of a device consisting of a filling cup or funnel whose outlet
is closed by a valve controlled by a weighted lever, as a safety valve for and as
a means for filling the cylinder and boiler of domestic hot water apparatus, arranged
and adapted to operate substantially as described.
