PROVISIONAL SPECIFICATION.
Improvements in or relating to Protectors for Gauge-glasses
and the like.
I, JOHN CLIFTON, of 191, Douglas Road, Parkwood Springs, Sheffield, in the
County of York, Engineer, do hereby declare the nature of this invention
to be as follows:-
-
This invention relates to improvements in protectors for gauge-glasses or the
like its object being to protect the attendant from accidents which often occur
through the breaking of such glasses when fitted to boilers or the like.
In carrying out my invention I form a shield of iron, tin, brass or any suitable
material either curved, flat, angular or semi-circular or of any convenient shape
so that it may be placed in front of the gauge-glass or glasses. One or more
sighting slots of any desired shape are formed in the shield. Slots or recesses are
preferably formed at the top and bottom of the shield which engage with por-
tions of the fittings in which the gauge-glass is mounted, or with projections upon
such fittings or upon adjacent parts of the boiler. Conveniently the slot at the
top of the shield may be longer than that at the bottom so that the shield may be
removed by simply lifting it up, and withdrawing it.
On the inside of the shield and of any suitable length and shape according to
the length of the gauge-glass I place a thick piece of transparent material prefer-
ably plate-glass, longer than the sighting slot on the shield and fixed or fastened
to the shield behind the slot. If desired this glass may be arranged so as to be
casily removed for cleaning purposes.
Through the sighting slot and the plate glass attached at its back the gauge-
glass is distinguished and read.

I, JOHN CLIFTON, of 191, Douglas Road, Parkwood Springs, Sheffield, in the
County of York, 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:—
This invention relates to improvements in protectors for gauge-glasses or the
like its object being to protect the attendant from accidents which often occur

preferably formed at the top and bottom of the shield which engage with por-
tions of the fittings in which the gauge-glass is mounted, or with projections upon
such fittings or upon adjacent parts of the boiler. Conveniently the slot at the
top of the shield may be longer than that at the bottom so that the shield may be
removed by simply tifting it up, and withdrawing it.
On the inside of the shield and of any suitable length and shape according to
the length of the gauge-glass I place a thick piece of transparent material prefer-
ably plate-glass, longer than the sighting slot on the shield and fixed or fastened
to the shield behind the slot. If desired this glass may be arranged so as to be
easily removed for cleaning purposes.
Through the sighting slot and the plate glass attached at its back the gauge-
glass is distinguished and read.
In the accompanying drawings which illustrate one construction of gauge-glass
protector according to this invention,
Figure is a front elevation showing the protector in position on the gauge-
glass fittings.
Figure 2 is a side elevation of the same.
Figures 3, 4 and 5 are respectively front elevation, side elevation and plan of
the protector.
Like letters indicate like parts throughout the drawings.
A is a shield covering the front and sides of a gauge-glass B, and provided
with slots and C' by means of which it is attached to studs E E upon the
gauge-glass fittings D. The slot C is longer than the slot C in order that the
shield may be readily removed by merely lifting it until the slot C is out of
engagement with the stud E' and then withdrawing the upper slot C from engage-
ment with the corresponding stud E. A sighting slot F is made in the front
portion of the shield so that the position of the water in the gauge-glass B may be
readily observed, the length of the sighting slot of course varies with the length
of the gauge-glass. A bar or strip G, preferably of light metal, it attached to the
back of the shield A just above the top of the sighting slot F, and another strip G
is attached in a corresponding position below the slot, this second strip Gt being
provided with a ledge G. A strip H of transparent material, preferably plate-
glass, is formed to fit in the space between the shield and the strips G G₁ and to
rest upon the ledge G, thus covering the slot F but allowing the gauge-glass to
be seen.
The strip of glass H can be readily removed for cleaning or renewal by
sliding it up between the shield and the strip G. If desired the strip of glass
H may be retained in its position by any convenient fastening.
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. The combination with a gauge-glass of a removable shield A having
slots CC one longer than the other substantially as and for the purpose described.
2. A gauge-glass protector comprising a removable shield A having a sighting
slot behind which a transparent substance H is retained by a bar G and a
ledge G G substantially as and for the purpose described.
3. The complete gauge-glass protector substantially as described and illustrated
in the accompanying drawings.
