PROVISIONAL SPECIFICATION.
Improvements in Automatic Arrangements for Gauge Glass
Mountings.
GEORGE BEAUFORT RICHARDS Croslands Villa Barrow in Furness Engineer
do hereby declare the nature of this invention to be as follows:-
The improvement applies to automatic fittings of the "ball valve" type (in
which on the breaking of a guage glass, the momentum of the escaping fluid
forces the ball valve to close the orifice of the gauge glass mounting leading to the
boiler) and consists of arranging such a ball valve to act in conjunction with a
central spindle running through an open bottom cock, applied to gauge glass
mountings as described in my Provisional Specification No. 21012, (1891), so that
the ball may be pushed off its seat when the glass is replaced, or for blowing thro'.

COMPLETE SPECIFICATION.
Improvements in Automatic Arrangements for Gauge Glass
Mountings.
I, GEORGE BEAUFORT RICHARDS, of Crosslands Villa, Barrow-in-Furness, in
the County of Lancaster, 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 :-
My invention relates to improvements in the automatic arrangements of gauge-
glass mountings.
The arrangement is preferably applied to duplex-gauge-glass fittings, so arranged
that either glass can be put in communication with the boiler, thus leaving one
glass always ready for use should the other one burst, (see Fig. 1.) but it may also
be applied to a single glass as shown in Fig. 2. The arrangement consists of a
ball A in conjunction with a spindle B. The spindle B is made sufficiently long to
admit of the ball A being pushed from its seat. The spindle B is kept fluid-tight
by means of a gland D in the spindle of the cock C. The cock C is an open
bottom one with a single port in the side, to allow of either glass being put in
communication with the boiler. Guard plates E are put between the glasses to
prevent splinters of one glass breaking, from breaking the other glass.
In the event of glass breaking, the action is as follows. The rush of the
escaping fluid forces the balls A against their seats, and prevents any further
escape. To bring the other glass into action, shut the cocks C, and, by means of
the spindle B, force the ball A from its seat, then open the cocks C to the other
glass, keeping the spindle B pressed in.
Having now particularly described & 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 :-
(1.) A spindle & ball arranged in conjunction as an automatic gauge-glass
fitting, constructed & operated substantially as described, with reference to the

page_text: (2.) A spindle & ball arranged in conjunction & in connection with duplex
gauge-glasses, constructed & operated substantially as described, with reference to
the accompanying drawings.
Dated this 17th day of September 1892.
GEORGE BEAUFORT RICHARDS.
