Improvements in Water Gauge Glasses for Steam Boilers and
the like.
I, JOHN EDWARD LEWIS OGDEN, of 51 Lyham Road, Brixton, London S.W.
Engineer, do hereby declare the nature of this invention to be as follows:-
My invention has reference to an improved method of arrangement of steam
gauge glasses, the object being to obviate the inconvenience and trouble which
arises by the glasses bursting when used with high pressure steam.
In carrying my invention into effect I employ a duplicate indicator, one in the
form of an ordinary gauge glass with the steam and water cocks connected
therewith, while the other has passages running from the supply cocks which feed
the gauge glasses for feeding an independent cylinder or tube in which I place a
float. I connect to this float, which is carried within the independent tube, a
spindle or indicator leg which passes through an opening formed in the lower end
of the cylinder wherein is placed a smaller gauge glass filled only with water as it
bas a dead end.
The want of circulation in the bottom gauge glass permits of the temperature of
the water therein being maintained fairly constant, while the spindle or indicator
leg rising within the locked in column of water within the glass will indicate the
height of the water and steam in the upper cylinder through which the float
travels.
In the event of my main gauge glass breaking I turn the steam and water
connections off for supplying that glass, and allow the water and steam only to feed
the independent float cylinder, and the level of the pointer end shown in the water
column in the lower gauge glass will make known to the attendant the position of
the steam and water in the boiler according to previously determined marking upon
the glass or scale placed in connection therewith.
Instead of using duplicate gauge glasses combined with the float I sometimes
dispense with the ordinary gauge glass and employ only the float and the indicator
lower spindle travelling in a locked or still column of water in a gauge glass and
allow this to be sole gauge glass for use in connection with the steam boiler or other
apparatus to which it is to be attached.
I may make my float of metal or other suitable material and I employ any
ordinary fittings for mounting the glasses and arrange test cocks in connection
therewith for indicating the steam and water level independently of the gauges.
I modify the arrangement of my cylinder and float and its mountings to suit the
type of boiler or apparatus to which it is to be attached.

Improvements in Water Gauge Glasses for Steam Boilers and
the like.
1, JOHN EDWARD LEWIS OGDEN, Engineer (late of 51 Lyham Road, Brixton,
London, S.W.) but now of "Penshurst," Vernon Road, Leytonstone, in the County
of Essex, 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 has reference to an improved method of arrangement of water and
steam gauge glasses, the object being to obviate the inconvenience and trouble
which arises by the glasses bursting when used with high pressure steam.
In the accompanying sheet of explanatory drawings-
Figure 1 is a sectional elevation of one form of my improved water gauge glass,
Figure 2 is a modified arrangement of my improved system, and
Figure 3 is an elevation of an alternative method of mounting my improved glass
which I sometimes employ.
In carrying my invention into effect I employ a duplicate indicator, one in the
form of an ordinary water gauge glass A with the steam and water or waste cocks
sometimes connected therewith, while the other has passages running from the
supply column B or cocks C which feed the gauge glass and also feed an
independent cylinder or tube B in which I place a float D. I connect to this
float, which is carried within the independent tube or cylinder, a spindle or
indicator leg E which passes through an opening 6 formed in the lower end of the
cylinder B wherein is placed a gauge glass A filled only with water as it has a dead
end a and a blow off cock F in connection therewith.
The want of circulation in the bottom gauge glass A permits of the temperature
of the water therein being maintained fairly constant, while the spindle or indicator
leg E rising and falling within the locked in column of water within the glass will
indicate the height of the water in the boiler and in the upper cylinder in which
the float travels.
In the event of a main or ordinary gauge glass breaking I sometimes turn the
steam and water connections off for supplying that glass, and allow the water and
steam only to feed the independent float cylinder, and the level of the pointer end
shown in the water column in the lower gauge glass will make known to the
attendant the position of the steam water level in the boiler.
Instead of using duplicate gauge glasses combined with the float I sometimes
dispense with the ordinary gauge glass and employ the arrangement as illustrated
in Figures 1, 2 and 3 having the float and the indicator lower spindle E travelling
in a locked or still column of water in a guage glass A and allow this to be the sole
gauge glass for use in connection with the steam boiler or other apparatus to which
it is to be attached.
I may make my float D of metal or other suitable material and I employ any
ordinary fittings for mounting the glasses and arrange test cocks in connection
therewith for indicating the water level independently of the gauges.
I sometimes make a balance float chamber B1 B2 as shown in Figure 2 and I then
connect the float D' by means of a chain or cord d to another balance float D
which rises and falls in the separate locked column of water in B².
When desired 1 reverse the position of my gauge or indicator glass as shown in
Figure 3 in which case the glass A' is filled with steam only and the indicator E¹
rises and falls in the column of steam.
I may place taps and cocks in connection with my gauge glass A and also on the

page_text: upper end of the chamber B when so desired for blowing out or other purposes.
I make my float of metal or other suitable material.
I modify the arrangement of my cylinder and float and its mountings to suit the
type of boiler or apparatus to which it is to be attached.
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-
1. The improvements in water gauge glasses for steam boilers and the like
substantially as and for the purposes hereinbefore described.
2. In a water gauge glass or apparatus for indicating the steam and water level
in a steam boiler the combination of a glass indicating column in which a pointer or
leg can rise and fall with a separate steam and water column or chamber in which
a float may be carried to give the rising and the falling motion to the indicating
stem or leg substantially as and for the purposes hereinbefore described and as
illustrated in the accompanying drawings.
3. In a water gauge glass for steam boilers and the like the combination and
arrangement of a water and steam column having two ordinary connections with
the boiler for carrying a float within it with a separate indicating glass or vessel
which has the water or steam within it in a comparatively quiescent condition,
substantially as hereinbefore described and as illustrated in the accompanying
drawings.
