Improvements in and relating to the Mountings or Fittings of Water
Gauge Glasses for Boilers,
I, GEORGE BARKER, Fellow of the Chartered Institute of Patent Agents, of
77, Colmore Row, Birmingham, in the County of Warwick, Consulting Engineer,
do hereby declare the nature of the said invention, as communicated to me from
abroad by Alfred Gariel, Engineer in the Italian Royal Navy, to be as follows:-
My invention has for its object improvements in and relating to the mountings
or fittings of water gauge glasses for boilers which are so constructed and
arranged as to prevent accident and the escape of steam when such glasses are
broken.
I fix to the boiler two plugs or taps and the bodies of the taps are connected
or fitted with two arms at the end of which is a strong spiral spring which is
kept open or in action by the gauge glass while it is in its unbroken condition.
In the event of the gauge glass being broken by internal pressure or concussion.
externally the arms are immediately brought together by the powerful spring
aforesaid which action closes the steam taps and effectively prevents any further
escape of steam. A new glass can then be applied without difficulty or without
tools and by any person in a simple and expeditious manner. The gauge glass
is covered by a wire or other netting which prevents the broken glass from flying
about while it does not prevent the water level from being clearly seen and
read.

Improvements in and relating to the Mountings or Fittings of Water
Gauge Glasses for Boilers.
I, GEORGE BARKER, Fellow of the Chartered Institute of Patent Agents, of
77, Colmore Row, Birmingham, in the County of Warwick, Consulting Engineer,
do hereby declare the nature of the said invention, as communicated to me from
abroad by Alfred Gariel, Engineer in the Italian Royal Navy, and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
-
My invention has for its object improvements in and relating to the mountings
or fittings of water gauge glasses for boilers which are so constructed and
arranged as to prevent accident and the escape of steam when such glasses are
broken.

page_text: I fix to the boiler two plugs or taps and the bodies of the taps are connected
or fitted with two arms at the end of which is a strong spiral spring which is
kept open or in action by the gauge glass while it is in its unbroken, condition.
In the event of the gauge glass being broken by internal pressure or concussion
externally the arms are immediately brought together by the powerful spring
aforesaid which action closes the steam taps and effectively prevents any further
escape of steam. A new glass can then be applied without difficulty or without
tools and by any person in a simple and expeditious manner. The gauge glass
is covered by a wire or other netting which prevents the broken glass from flying
about while it does not prevent the water level from being clearly seen and
read.
In order that my invention may be more clearly understood and easily carried
into practical effect I have appended hereunto a double sized sheet of drawings
upon which I have illustrated an example of my mountings or fittings for water
gauge glasses for boilers.
Figure 1 is a front elevation of my fittings shewing the water gauge glass
fitted in position.
Figure 2 is a side elevation of Figure 1.
Figure 3 is a part sectional plan view of Figure 1.
In carrying my invention into practice I fix to the front of the boiler the
plugs or taps A and A¹ in the usual manner by bolts or the like passing through
the holes a formed in the flanges a³. Connected or fitted to the bodies of these
taps are the branch pipes B and B communicating with the taps A and A¹ and
in the ends or sockets 6 of these branch pipes the gauge glass D is fitted. Formed
on or connected to the ends 62 of these branch pipes are the arms or projec-
tions and band attached to the ends of these arms is the spiral spring S which is
kept open or in tension by the gauge glass D) as this glass holds the arms
and and consequently the branch pipes B and B apart or in their normal
positions. The branch pipes B and B are connected to the bodies of the taps A
and A by the taps or socket pieces 6, which fit over the bodies or ends of these
taps and are free to swivel thereon so that when held in the normal position by
the gauge glass the openings of the passages a¹ are in direct communications
with the openings of the passages 6 of the branch pipes the water being free to
pass to the gauge glass as clearly shewn at Figure 3 but in the event of the gauge
glass being broken by internal pressure or concussion externally the communi-
cations between the passages 7 and at is instantly cut off-that is to say-the
arms 63 and 6 are immediately brought together by the action of the spring S
and consequently the branch pipes B and B₁ turn or move on their socket
pieces thereby moving the openings of the passages 66 out of communication
with the openings of the passages a thus shutting off the communication and
effectually preventing any escape of steam and allowing the attendant or fire
man to turn off the taps A and A¹. A new gauge glass can then be fitted with-
out difficulty or without tools and by any person in a simple and expeditious
manner. The gauge glass D is covered with wire or other netting for pre-
venting the glass from flying about when broken but at the same time it does
not prevent the water level from being clearly seen and read.
The lower end of the spring S is preferably attached to the loose swivel f
mounted on the end of the screwed spindle F working in a tapped hole formed in
the end of the arm b* provided for the purpose of adjusting the tension of the
spring, which spindle is operated by the handle f2 fixed to the other end of the
spindle.
my said
Having now particularly described and ascertained the nature of
invention, and in what manner the same is to be performed, I declare that what
I claim is:
CLAIM.

page_text: glasses for boilers consisting of the two arms or levers or their equivalents con-
nected with the gauge glass sockets the said sockets being capable of turning
the tap for. breaking the connection with the boiler and gauge glass in com-
bination with the spring S or its equivalent as and for the purpose herein set
forth and as shewn in the accompanying drawings.
