IMPROVEMENTS IN WATER-GAUGES
Year: 1884

page_text: I HENRY HARRIS LAKE, of the firm of Haseltine, Lake, & 0° Patent Agents,
Southampton Buildings London, in the County of Middlesex do hereby declare
the nature of said Invention for "IMPROVEMENTS IN WATER-GAUGES" to be as
follows:-
This Invention relates to water-gauges.
In water-gauges as heretofore constructed it frequently happens that even with
the most skilful manipulation the glasses of the same will break, this breakage
resulting from the employment of stuffing boxes for rendering the joints around
the glasses water tight.
The object of the said Invention is to obviate this defect and it comprises the
novel construction hereinafter described.
In carrying the said Invention into practice I provide the water-gaugo with a-
piston arranged in an upper casing and with a second piston arranged in a lower
casing.
The opposite faces of the said pistons are provided with annular grooves in
which are placed gutta-percha rings or the like; these two rings serve to make tho
gauge-glass water-tight at both ends.
The gauge-glass is secured between the above mentioned pistons by turning a
screw operating in a frame the lower part of which is connected with the second
piston.
A spherical valve supported in the upper piston by a spiral spring is held in its
place at the top of the said piston by a wire or the like while a lower valve is
capable of moving upon a pivot and is held by means of a shoulder-piece in such a
manner that it does not open when in a vertical position relatively to the said.
pivot.
.
In order to indicate when the two valves are open two rods project beyond the
faces of the pistons and enter the gauge-glass. When a gauge glass is broken the

page_text: upper valve carried by the spiral spring is closed by the steam which presses upon
the said valve and compresses the spring. The lower valve is closed by the water
from below upward. Before adjusting a fresh gauge-glass, the two gauge-cocks are
closed and the drain cock is opened which causes also the lower valve to open.
When the glass has been adjusted the drain-cock is closed and the lower gauge-
cock is slowly opened whereupon the upper valve also opens. After the upper
gauge-cock has been opened the water-gauge is ready to operate.

HASELTINE, LAKE & Co.,
For the Applicant.
Southampton Buildings, in the County of Middlesex do hereby declare the nature
of my Invention for "IMPROVEMENTS IN WATER-GAUGES" and in what manner
-the-same is to be performed, to be particularly described and ascertained in and by
the following statement:--
This Invention relates to water-gauges.
In water-gauges as heretofore constructed it frequently happens that even with
the most skilful manipulation the glasses of the same will break, this breakago
resulting from the employment of stuffing boxes for rendering the joints around
the glasses water-tight.
The object of the present Invention is to obviate this defect, and to this end it
comprises the novel construction hereinafter described.
In the accompanying Drawing
Figure 1 is a vertical section of a water-gauge constructed according to this
Invention, and
Figure 2 is a front elevation of the same.
A indicates the upper casing within which slides a tubular stem C, and B the
lower casing having a tubular stem C'.
The outer end of each stem C C¹ is provided with an annular groove in which is
placed a ring g of gutta percha or the like. These two rings serve to make the
joints at the ends of the gauge glass water-tight.
The gauge-glass is secured between the above mentioned stems by turning the
screw, which raises the frame o connected with the stem C' and with it the said
stem whereby the latter is raised and caused to hold the glass between the
rings 9, 9.
A spherical valve vis supported at the upper end of the stem C by a spiral
spring fand is retained in position by a wire 8.
A valve v is also pivotted to the lower stem C¹.
In order to indicate when the two valves vv are open two rods i i¹ project out
beyond the faces of the stems C, C' respectively and enter the gauge glass l.
When a gauge glass breaks, the valve v, is closed against the pressure of the
spring by reason of the rush of steam through the tubular aperture in the stem C.
The valve v is also closed by the rush of water.

page_text: Before replacing a gauge glass, the two gauge-cocks are closed and the drain
cock is opened, thus relieving the pressure below the lower valve v¹ and allowing
it to open. When the glass has been adjusted the drain cock is closed and the
lower gauge cock is slowly opened, whereupon the upper valve, by reason of the
upward pressure of the spring fand the pressure within the glass, is also
opened. After the upper gauge-cock has been opened the water-gauge is again in
operation.
•
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:
First. In a water-gauge, fixing the gauge glass between the two stems C C¹ by
means of the screw and frame o, substantially as described.
Second. In a water gauge the valves supported by a spring and provided with.
the indicating rod i, and the valve v moving upon a pivot and having the indicating
rod, substantially as set forth.
