PROVISIONAL SPECIFICATION.
Improvements in Water Gauges.
1 GEORGE HENRY WALL of Lindridge House, 98 Upper Tulse Hill,
London, S.W. Engineer, do hereby declare the nature of this invention to be as
follows:-
It is desirable that a protector, the object of which is to prevent injury to
persons through the bursting of a water gauge tube, should be both easily applied
to and removed from the water gauge, and it is also desirable that it should be
capable of being applied without having to make any additional parts or
alterations in the water gauge itself; but should such in any case be required to
be made they should be simple and of general application.
The
My present invention embraces improvements on those protectors described and
illustrated in the Specification of Patent No. 16,075 of 1889 granted to me.
upper glass-holder of the protector is surmounted with a ring that rests upon the
upper arm or body of the water gauge and is held in its position laterally by
fitting around the usual top cap or plug that closes the orifice through which the
glass tube is introduced.
The ring is suitably connected by bars on either side to the glass-holder, and
they are sufficiently far apart to clear the body of the water gauge and the
stuffing-box nuts; the ring, the side or connecting bars, and the top glass-holder.
I prefer to cast in one piece. For appearance sake I sometimes place the
connecting bar or bars in the front of the glass-holder instead of at the sides.
The lower glass-holder of the protector is made to fit partly around the most
convenient part of the lower stuffing-box; in some cases it may be around the nut
itself and in other cases around a projecting part of the gland.
It may be desirable sometimes to prevent the protector from being lifted, in
which case a split-pin passed through a hole in the top cap or a stop piece on the
cap or a set screw or pin in the side connecting bars or similar device may be
employed; whichever of these arrangements is adopted when it is released the
protector when lifted up above the level of the lower stuffing-box nut, or above
the level of the top cap can be removed. The foregoing improvements are not
only applicable to protectors made in accordance with the hereinbefore mentioned
Specification but also to those of any other shape or construction.

I GEORGE HENRY WALL of Lindridge House, 98 Upper Tulse Hill,
London, S.W. 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 :—
It is desirable that a protector, the object of which is to prevent injury to
persons through the bursting of a water gauge tube, should be both easily applied.

capable of being applied without having to make any additional parts or
alterations in the water gauge itself; but should such in any case be required to be
made they should be simple and of general application.
My present invention embraces improvements on those protectors described and
illustrated in the Specification of Patent No. 16,075 of 1889 granted to me.
The upper glass holder D of the protector is surmounted with a ring marked B in
Fig. 1 of the accompanying drawings. This ring is suitably connected by
bars A, A, on either side to the glass holder D, and they are sufficiently far apart
to clear the body of the water gauge and the stuffing-box nuts. The ring B rests
upon the upper arm or body of the water gauge and is held in its position laterally
by fitting around the usual top cap or plug C that closes the orifice through which
the glass tube is introduced.
The ring B, the side connecting bars A, A and glass holder D, I prefer to cast
in one piece. It may be desirable sometimes to prevent the protector from being
lifted, in which case a split pin G passed through a hole in the top cap C, or a set
screw or some such similar device may be employed.
The lower glass-holder E is made to partly surround the stuffing-box nut F.
To remove the protector it would be only necessary to lift it above the level of
the lower stuffing-box out F and the top cap C. It is manifest the connecting
bars A, A, may be placed in the front instead of at the sides of the water gauge.
Fig. 2 is a front elevation of the protector attached to a water gauge.
Fig. 3 is a front elevation of the protector removed from the water gauge and
Fig. 4 is a plan of the same through line X, X from which it will be seen that it
has three plates of glass. In some cases the two side plates may with advantage
be made of metal.
Fig. 5 is a front elevation of a protector arranged to be supported as in Figs. I
and 2, and Fig. 6 is a plan of the same through line X, X, which shows the metal
side plates H, H, and front glass plate J..
Fig. 7 is a front elevation of a protector arranged to be supported as in Figs. 1
and 2, and Fig. 8 is a plan of the same through line X, X, which shows a
provision for cementing the front glass plate K, into gutter or channel shaped
metal side plates L, L.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
The improved apparatus and arrangement whereby a protector is attached to a.
water gauge substantially as hereinbefore described and illustrated by the
accompanying drawings.
