AUTOMATIC WATER GAUGES FOR STEAM BOILERS
Year: 1884

page_text: I THOMAS CROOK of Black-Horse yard, Preston, in the County of Lancaster,
Brass founder, do hereby declare the nature of my invention for AUTOMATIC
WATER GAUGES FOR STEAM BOILERS, to be as follows:-
There is a metal valve with its seating towards the pressure in the boiler which
works horizontally, in the inlet of the gauge, the valve has two skue-slots cut in
its guide which is connected to a spindle (with two lugs on) passing to the front,
and with a slight turn of the spindle to the right the valve is drawn to its seat,
with a turn to the left, the valve opens, thus doing away with the plug taps, the
lugs on the spindle being free in the skue slots of the valve, alows it to be forced
to its seat by the pressure in the boiler when the pressure loses its equilibrium
caused by a sudden outlet from glasses breaking, or otherwise.

page_text: THOMAS CROOK of Black Horse Yard Preston in the County of Lancaster
Brass Founder do hereby declare the nature of my invention for AUTOMATIC
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:
This Invention is an Automatic Water Gauge; and consists in the application of
a loose Valve, in the inlet port for water and steam, and further in the arrange-
ment of a spindle; forming a steam tight joint in the body of the Gauge.
Figures 1 & 2 show Vertical Sections of the Gauge at right angles.
Fig. 3 shows spindle C, with faceing D, and prongs.
Figures 4 & 5 show end, side, and plan View, of Valve A, through S S. The
Valve A is a loose Valve, which works in the inlet port B for steam and water,
the Spindle C, has a faceing, D, and is guided by the port, B, and stuffing box E,
and revolved by lever H, and is coupled by the prongs on spindle C, C, in the
slots of Valve A.
The body N, serves as a seat for Valves A, & D, and has also a projection, pin
or pins, P, so arranged as to form a cam or eccentric motion to the Valve A.
When the lever is turned up, the Valve A, is held open, by the projection P,
which allows the steam and water to flow in glass "G."
The lever being turned down, leaves the Valve in an Automatic position which
is closed by the pressure in the boiler; in case of a sudden outlet from the front,
caused by glasses breaking, or the opening of the bottom Valve, the prongs on
spindle C, and guides on Valve A, serve to remove any sediment that may adhere
to the Valve A, or port B.
-
There is a wheel Valve screwed in body N, as a cleansing or outlet Valve for
the glass "G." The Gauge glass fittings are made of Gun metal or other appriate
metal for the purpose.
Having now particularly described, and ascertained the nature of my Baid
Invention, and in what manner the same is to be performed, I declare that what
I claim is,-
I-The application and employment of a Valve in port B, arranged in such
manner as to cause the opening, or ports B, to be Automatically closed in case of
accidents from glasses breaking or its equivalent substantially as shewn and
described.
II The application of spindle C, with two or more prongs on, to remove and
clear the sediment from the slots in Valve A, and port B, substantially as shewn
and described.
III The projection P to force the Valve A, open, when the full side of the
eccentric shaped end of the Valve A, comes in contact with the projection P, as
described and shewn in the accompanying drawings.
