PROVISIONAL SPECIFICATION.
A Device to be used in connection with Water Level Indicators or
Liquid Gauges.
I, JAMES WILLIAM HELPS of the Gas Works, Croydon in the County of Surrey,
Gas Engineer and Manager, do hereby declare the nature of this Invention to be
as follows:-
-
My Invention relates to water level indicators, or liquid gauges; and has for
its object to provide a device for use therewith by which the actual position of the
level of the liquid in the indicator or gauge, can be ascertained with great
readiness, accuracy, and certainty, without the use of a coloured liquid for the
purpose, which coloured liquid, in time, loses its colour, and also so affects the
sides of the interior of the indicator, or gauge, that they become obscured, and
so render difficult the observation of the level of the water or liquid in the
indicator or gauge. By the use of a device according to my Invention not only
are the sides of the indicator or gauge not obscured by the use of coloured liquid
but the level of the water or liquid in the indicator or gauge can be seen from a
considerable distance which is an important advantage in certain cases for
instance in gas works. The device according to my Invention consists of a body
so weighted that its top or upper part will be level with or only very slightly
above the level of the liquid or water in the indicator or gauge its whole body or
the main portion of its body being submerged in the said liquid or water. If
the said device be made of a diameter slightly less than that of the indicator
or gauge tube and it be so weighted that its upper surface is level with the
surface of the liquid or water therein the said liquid or water will insure that the
said device does not adhere to the sides of the said tube as would be otherwise
liable to occur especially in cases where the contents of the said tube above the
liquid or water therein are liable to cause a sticky deposit on the sides of the said
tube. I prefer to make the said device of hollow glassware coloured so as to be
very distinctive and to make its lower part with a small well or depressed portion
at its centre in which the weight which maintains the device in proper position
in the liquid or water is placed. The said weight may be constituted by a globule
of mercury which will always tend to keep at the lowermost central point of the
device and so properly balance the device and keep it in its proper position as
aforesaid.

Prise 8d.1

page_text: in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
My Invention relates to water level indicators, or liquid gauges; and has for
its object to provide a device for use therewith by which device the actual position
of the level of the liquid in the indicator, or gauge, can be ascertained with great
readiness, accuracy, and certainty, without the use of a coloured liquid for the
purpose, which coloured liquid, in time, loses its colour, and also so affects the
sides of the interior of the indicator, or gauge, that it becomes obscured, and so
the observation of the level of the water, or liquid, in the indicator, or gauge, is
greatly impeded. By the use of a device according to my invention, not only
are the sides of the indicator, or gauge, not obscured by the use of coloured
liquid, but the level of the water, or liquid, in the indicator, or gauge, can be
seen from a considerable distance, which is an important advantage in certain
cases; for instance, in gas works. The device according to my invention is
illustrated in elevation in Figure 1, and in section in Figure 2, of the accompany-
ing drawing. Figure 3 shews a gauge with such a device in each leg. The
device consists of a body A, so weighted that its top, or upper, part will be level
with, or only very slightly above, the level of the liquid, or water, in the indicator,
or gauge; its whole body, or the main portion of its body, being submerged in
the said liquid, or water. If the said device be made of a diameter but slightly
less than that of the indicator or gauge tube, and it be so weighted that its upper
surface is level with the surface of the liquid, or water, therein the said liquid,
or water, will insure that the said device does not adhere to the sides of the said
tube, as would be otherwise liable to occur, especially in cases where the contents
of the said tube above the liquid, or water, therein are liable to cause a sticky
deposit on the sides of the said tube. I prefer to make the said device of hollow
glassware, coloured so as to be very distinctive, and to make its lower part with
a small well, or depressed portion, at its centre, as shewn at a, in which the
weight, which maintains the device in proper position in the liquid, or water, is
placed. The said weight may be constituted by a globule of mercury, as shewn
at b, which will always tend to keep at the lowermost central point of the device,
and so properly balance the device, and keep it in its proper position as aforesaid;
but I do not limit myself to this method of weighting. For example, the
necessary weight may be provided by the material of the device itself or be
suspended from it.
Having 110W particularly described and ascertained the nature of this
invention and in what manner the same is to be performed, I declare that what
I claim is:
1. A device, for the purpose described, consisting of a body so formed and
weighted that it will be entirely submerged, or practically entirely submerged,
in the liquid the height of which is to be measured, and its upper surface be level,
or about level, with the top of such liquid, substantially as hereinbefore described.
2. A device, for the purpose described, consisting of a hollow body with a
central depression for containing mercury, or other weight; substantially as
hereinbefore described and illustrated in the accompanying drawing
