IMPROVE- MENTS IN WATER GUAGES FOR STEAM BOILERS
Year: 1884

page_text: I SAMUEL MORLEY of No 27 Lorne Street Stockton on Tees in the County of
Durham Engineer do hereby declare the nature of my invention for IMPROVE-
MENTS IN WATER GUAGES FOR STEAM BOILERS to be as follows:-
At the present time accidents frequently arise from the water guages of Steam
boilers becoming obstructed either by sediment or corrosion or from other causes
and allowing water to remain in the guage above the water level in the boiler, and
by which engineers are frequently scalded through the guage glass breaking and
allowing the escape of steam.
My invention has mainly for its object to ensure the keeping clear of the
entrances to the guage and thereby maintain the guage in proper working order.―
For this purpose I provide a small plunger which works through a stuffing box on
the front of the shell of the guage. On the end of the plunger is a fluted cutter
and in the inside of the cutter is a mitre which. will fit into a steamtight mitre in
the inside of the shell-On the outer end of the ram of the plunger is either a wheel
or handle by which the engineer may at any time by turning or pulling out
horizontally remove any sediment which may be formed-The main object of the
plunger and the inner mitre is that in case the guage glass should break, the
pressure acting on the surface of the fluted cutter of the ram will immediately of
itself force out the ram against the inner mitre of the shell and shut off the steam
and water independent of the engineer and thus prevent the engineers and stokers
from being scalded. The advantage of these two self acting valves is also that
they are both in the control of the engineer as well as self acting, and also in case
of anything going wrong with either of the higher or lower valves of the guage
the engineer may use the plunger in substitution until the guage glass is replaced.

COMPLETE SPECIFICATION.
I SAMUEL MORLEY of No. 27 Lorne Street Stockton on Tees in the County of
Durham Engineer do hereby declare the nature of my invention for IMPROVE-
MENTS IN WATER GAUGES FOR STEAM BOILERS, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement :-
At the present time accidents frequently arise from the Water Gauges of Steam
Boilers becoming obstructed either by sediment or corrosion or from other causes

and by which Engineers are frequently scalded through the Gauge Glass breaking
and allowing the escape of Steam..
My invention has mainly for its object to ensure the keeping clear of the
entrances to tlie Gauge and thereby maintaining the Gauge in proper working
order. For this purpose I provide a small plunger which works through a stuffing
box on the front of the shell of the Gauge. On the end of. the plunger is a fluted
cutter and in the inside of the cutter is a mitre which will fit into a steam tight
mitre in the inside of the shell. On the outer end of the ram of the plunger is
either a wheel or handle by which the Engineer may at any time by turning or
pulling out horizontally remove any sediment which may be formed. The main
object of the plunger and the inner mitre is that in case the Gauge Glass should
break the pressure acting on the surface of the fluted cutter of the ram will
immediately of itself force out the ram against the inner mitre of the shell and
shut off the Steam and Water independent of the Engineer and thus prevent the
Engineers and Stokers from being scalded.
The advantage of these two self acting valves is also that they are both in the
control of the Engineer as well as self acting and also in case of anything going
wrong with either of the higher or lower valves of the Gauge the Engineer may
use the plunger in substitution until the Gauge Glass is replaced.
P is the end of the Plunger which is fitted within the Water way which when
pulled or revolved hoizontally removes the sediment lodged in the water way.
V. is the Valve which is fitted to the other end of the plunger, and in case tlio
Glass breaks the pressure inside the Boiler acting on the plunger P forces it into
the inner shell and shuts the Steam or Water off. G is the stuffing Box on the
front of the Gauge. S. is the Spindle which works through the stuffing Box. Wis
the Wheel which opens and shuts the valve. A represents a front view of the
plunger end which is fluted to allow the water to pass through the shell into the
Glass. B is the blow off Valve.
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
In Water Gauges a plunger fitted and working horizontally in the Water way
of the Gauge fitted with a mitre Valve at the end, so that in case the Glass of the
Gauge breaks the pressure of Steam in the Boiler acting on the end of the plunger
forces the mitre into its seat, makes it Steam tight and thus prevents scalding by
escape of Steam, the Valve being Automatic or manual substantially as shewn and
described.
