PROVISIONAL SPECIFICATION.
Improvements in Shields or Protectors for Use with Water
Gauge Tubes.
1, ALEXANDER SPENCER, of 77 Cannon Street, in the City of London, Engineer,
do hereby declare the nature of this invention to be as follows:-
This invention has reference to improved constructions of shields or protectors
(hereinafter called protectors) for use with water gauge tubes.
According to one construction, the protector comprises a casing adapted to bo
secured in place in front of a water gauge tube so as to partly surround the same,
and one or more mirrors adapted to be supported behind the said tube the arrange-
ment being such that the height of water in the tube can be readily seen by
reflection from the mirror or mirrors instead of by direct observation of the tube
through the casing in front of the tube.
In an arrangement of this kind, the casing consists of reticulated or perforated
material provided with spring clips or equivalent means by which it can be readily
fixed either to the water gauge tube or to the water gauge fittings, and also with
guides and supports for holding in position behind the tube, two vertical mirrors
arranged at an obtuse angle to each other, the apex of the angle being nearer to
the tube than the outer edges of the mirrors. The mirrors may be of silvered glass
held in a removable frame or of metal, and the tube may be of the kind having a
white or opaque side to enable the height of water therein, to be more readily
sceu.
According to another construction the protector consists simply of a reticulated
or perforated casing with spring clips for attachment to the water gauge tube or
with equivalent means for attachment to the water gauge fittings. The casing
when of woven wire may be strengthened at its edges by a sheet metal frame.
When one or more mirrors is or are employed, the casing may be of plain sheet
metal surrounding the tube on all sides excepting the back.

COMPLETE SPECIFICATION.
Improvements in Shields or Protectors for Use with Water
Gauge Tubes.
1, ALEXANDER SPENCER, of 77 Cannon Street, in the City of London, Engineer,
do hereby declare the nature of this iuvention 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 reference to improved constructions of shields or protectors
(bereinafter called protectors) for use with water gauge tubes.

page_text: According to one construction, the protector comprises a casing adapted to bo
secured in place in front of a water gauge tube so as to partly surround the same,
and one or more mirrors adapted to be supported behind the said tube, the arrango-
ment being such that the height of water in the tube can be readily seen by
reflection from the mirror or mirrors instead of by direct observation of the tube
through the casing in front of the tube.
Referring to the accompanying drawings Fig. I is a central vertical section,
and Fig. 2a plan, partly in section on the line Fig. 1, showing an arrangement
of this kind. The casing 1 consists of reticulated material, such as woven wire,
strengthened at its edges by a sheet metal frame 1 and provided with spring
clips 2 of sheet metal by which it can be readily fixed to the water gauge tube 3
and also with guides 4 of wire and supports 5 of sheet metal for holding in position,
behind the tube, two vertical mirrors 6 arranged at an obtuse angle to each other,
the apex of the angle being as shown nearer to the tube than the outer edges of
the mirrors. The clips 2 are mounted on cross pieces 2 attached (it may be by
rivetting) to the casing. The mirrors may be of silvered glass, held in a removable
frame, or of metal, and the tube may be of the kind having a white or opaque side
or back to enable the height of water therein, to be more rendily seen. The
casing, may, if preferred, be made of perforated or plain sheet metal instead of
woven wire. Also in place of clips 2 of the kind shown, any other convenient
attaching means may be employed, and if desired the clips or other attaching
means instead of being adapted to be fixed to the gauge glass may be adapted to
be attached to the gauge glass fittings.
Figs. 3 and 4 show an arrangement of this kind in which the upper and lower
ends of the casing are provided with clamps 2, 2 adapted to be secured around
the stuffing box nuts 8 8 respectively.
Fig. 5 is a vertical section and Fig. 6 a sectional plan, showing another
construction of protector according to this invention. In this case the protector
consists simply of a casing 1, which may be of reticulated or perforated material
through which the tube can be seen, the easing being provided with clips for
attachment to the water gauge tube, or it may be with equivalent means for
attachment to the water gauge fittings. In the example shown metal spring clips 2
are used formed of sheet metal bent to shape and secured to the casing by rivets 24
and a plato 2°.
When clips designed to fit gauge tubes are used, they should be lined with
suitable material such as cloth, asbestos or the like to prevent chilling of the tubes
when applied thereto.
Having now particularly described and ascertained the nature of the said inveu-
tion and in what manner the saine is to be performed 1 declare that what I
claim is :-
1. A protector for a water gauge tube comprising a casing adapted to be secured
in place in front of the tube so as to partly surround the same and one or more
mirrors arranged to be supported behind the said tube, the arrangement being such
that the height of water in the tube can be readily seen by reflection, substantially
as described.
2. My improved protectors for water gauge tubes, constructed as herein before
described with reference respectively to and shown in Figs. 1 and 2; in Figs. 3 and 4;
and in Figs. 5 and 6 of the accompanying drawings.
Dated this 28th day of November 1896.
