PROVISIONAL SPECIFICATION.
A New or Improved Water Gauge Protector for Steam Boilers.
I, ALEXANDER GRANT, of 124, Eastfield Street, Springburn, in the County of
the City of Glasgow, North Britain, Railway Engineer, do hereby declare the
nature of this invention to be as follows:-
1.1
This invention relates to a new or improved water gauge protector for all
classes of steam boilers and has for its object, in the case of the glass bursting
or giving way, to prevent the fragments flying out and striking those near at
hand, and also to prevent attendants getting their hands cut when in the act of
shutting off water and steam cocks.
In carrying out my invention, I provide a cylindrical casing of brass or any
other suitable metal or material. This casing is made in two sections which are.
hinged together. The front of the casing is provided with an opening having.
a guide on each side and a rest at the bottom. Into this opening a sheet of glass
or other transparent material is placed so as to enable the reading of the gauge to
be taken. This glass or other material is held in position by means of the guides
and rest. The back end is open but is provided with upright ribs of metal at
equal distances of say one-eighth of an inch or so apart and these are stayed.
by cross bars. The protector when being used is simply placed round the gaugo
columns and, the two ends are held together by means of a suitable clasp,
It has also a fine appearance besides being durable and extremely safe and
destined to prevent many accidents.

A New or improved water Gauge Protector for Steam bollers.
I, ALEXANDER GRANT, of 124, Eastfield Street, Springburn, in the County of
the City of Glasgow, North Britain, Railway Engineer, do hereby declare the
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 state.

-
My invention relates to a new or improved water gauge protector for all
classes of steam boilers and has for its objects, to protect gauge glass from acci-
dental breakage, and in the case of the glass bursting or giving way, to prevent

page_text: the fragments flying out and striking those near at hand, and also to prevent
injury to attendants when in the act of shutting off water and steam cocks.
In order that my invention may be properly understood and readily carried
into effect I have hereunto appended one sheet of drawings of which,
Figure 1 is a front elevation showing my improvements applied to a water
gauge glass.
Figure 2 is a front elevation of the protector drawn to an enlarged scale.
Figure 3 is a cross section of Figure 2.
Figure 4 is a plan.
In carrying out my invention, I provide a cylindrical casing A of brass or any
other suitable metal or material. This casing A is made in two sections which
are hinged together as shewn in the drawings, or they may be looped together on
either side. The front of the casing A is provided with an opening B having a
guide C on each side and a rest D at the bottom. Into this opening B a sheet
of rolled polished plate glass E or other transparent material either flat, curved
or bevilled and capable of withstanding great resistance is placed so as to enable
the reading of the gauge to be taken. This glass or other material is held in
position by means of the guides C and rest D. The back end of the protector
is open but is provided with an upright rib F of brass or other metal, which acts
as a reflecting bar. Two slips or catches G, forming part of the protector or
riveted or otherwise fixed thereto are also provided at back in order to suspend
or fix a lamp on so as to be able to take the readings of the gauge glass in the
dark. A wire gauze J is provided at back of protector and a similar gauze is or
may be fitted on the front at back of glass E to act as a cushion so as to
prevent the plate glass from becoming damaged in case of bursting of the gauge
glass. The protector when being used is simply placed round the gauge columns
and the two ends are held together by means of a suitable clasp, or as shewn in
the drawings by the longitudinal pin H being pressed through the loops I on
each side of the protector.
It has also a fine appearance besides being durable and extremely safe and
destined to prevent many accidents and is capable of being fitted to any gauge
columns on any boiler.
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:-
The water gauge protector for steam boilers constructed substantially as de-
scribed and illustrated on the accompanying sheet of drawings.
