PROVISIONAL SPECIFICATION.
An Improved Protector for Water-gauge Glasses.
I, CARL NEUHAUS, of 49 Landongasse, Vienna, VIII, Austria-Hungary,
Engineer, do hereby declare the nature of this invention to be as follows:-
The object of my invention is to provide a pretecting casing, of an angular
form, for water-gauge glasses, which easing surrounds the glass and the abutting
parts on the side next the observer, but leaves the boiler side open in such a
manner that a reflector arranged behind the glass, will enable the level of the
water to be sien, whilst at the same time throwing light upon the inner side of the
said casing which is provided with a white coating and with a red or other suitable
dark-coloured stripe at the back of the glass which will cause the water column to
appear in a dark col ur when reflected.
The glass of any suitable watergange is surrounded by an angular-shaped casing
on the side next the observer while the side towards the boiler is left open. The
snid casing is secured to water-gauge cocks by means of slotted extensions and
thumb screws or in any other suitable manner.
In order to observe the water level a reflector is arranged behind the gauge glass
and the angular casing. The said reflector can be arranged in any convenient
way. Preferably the reflector is attached to the casing by means of arms which
allow the reflector to be put in any desired position relatively to the gauge-glass or
to the observer. The said arms are hinged to lugs or eyes which are cast on both
sides of the casing in order to enable the reflector to be secured on either side of
the same. The reflector can also be constructed in an angular form, which enables
the looker on to observe the water level from either side of the water gauge. In
this way the edge of the angular-shaped reflector is placed opposite the glase and
both sides of the same diverge from the boiler..
In this way the water level is made visible by reflection, whereby the column of
the water in the gauge glass appears in a dark colour by means of the white inner
coating, and the red stripe on the casing. When using a protecting casing as
described, the level of the water only becomes distinctly visible, when the same is
arranged and constructed as herein set forth.

1, CARL NEUHAUS, of 49 Laudongasse, Vienna VIII, Austria-Hungary,
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 :-
The object of my invention is to provide a protecting casing, of an angular form,
for water-gauge glasses, which casing surrounds the glass and the abutting parts on

page_text: the side next the observer, but leaves the boiler side open in such a manner that a
reflector arranged behind the glass, will enable the level of the water to be seen,
whilst at the same time throwing light upon the inner side of the said casing which
is provided with a white coating and with a red or other suitable dark-coloured
stripe at the back of the glass which will cause the water column to appear in a
dark colour when reflected.
In the accompanying drawing
Figure 1 is a side elevation of a water-gauge with a sectional side elevation of
the protecting casing and the reflector,
Figure 2 a cross section on the line a-b and
Figure 3 a view from above of Figure 1.
The glass of any suitable water-gauge is surrounded by an angular-shaped
casing c on the side next the observer, as shown in Figure 2, while the side towards
the boiler is left open. The casing c is attached to the water-gauge cocks by
means of slotted extensions f, k passing over studs t, u, and by nuts g, 1 or in any
other suitable manner.
In order to observe the water-level a reflector mi is arranged behind the gauge-
glass and the angular casing. The said reflector can be arranged in any convenient
way. Preferably the reflector is attached to the casing by means of arms n, o
which allow the reflector to be put in any desired position relatively to the
gauge-glass or to the observer. The said arms are hinged to lugs or eyes n which
are provided on both sides of the casing in order to enable the reflector to be
secured on either side of the same. The reflector can also be constructed in an
angular form, which enables the observer to see the water-level from either side of
the water-gauge. In this way the edge of the angular-shaped reflector is place!
opposite the glass and both sides of the same diverge from the boiler.
In this way the water-level is made visible by reflection so that the column of
the water in the gauge glass appears in a dark colour by means of the white inner
coating and the red stripe on the casing. When using a protecting casing as
described, the level of the water only becomes distinctly visible, when the same is
arranged and constructed as herein set forth.
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
1. A protecting casing for water-gauge glasses, having an angular shape and
open only towards the boiler and provided with an inner white coating and a red
or other dark stripe near the gauge-glass, and with a suitably arranged reflector,
substantially as, and for the purposes, herein before described."
2. The modification of my invention in which the reflector is made of such form
as to enable the water-level to be observed from both sides of the water-gauge,
substantially as described.
