PROVISIONAL SPECIFICATION.
Improvements in Water Gauges and Gauge Cocks.
I, FREDERIC WILLIAM PRIESTLEY PARKER of Sale in the County of Tanjil
Victoria Australia Engineer do hereby declare the nature of this invention to be
as follows:-
Fig. 1. is a gauge cock made in two parts which are screwed together at S, with
spindle D, having screwed end H with two grooves in it T and O, forming the
passages to boiler. E is a ring of celluvert fibre, vulcanised fibre or inetal inserted
in groove..
Fig. 2. is a gauge cock similar to Fig. 1 with the exception that the grooves t
and o forming the passages to the boiler are made in the shell instead of in the
screwed part of spindle.
Figs. 3 and 4 are sections through lines 1-2 and 3-4 respectively shewing
formation of grooves T & O.
Figs. 5 and 7 are sections through a water gauge provided with a screwed
boss W for the reception of the gauge glass V. The spindle D in Figs. 5 and 7 is
constructed in the same manner as in Fig. 1. but may also be made if desired in
the manner shown in Fig. 2. The working action is as follows, by revolving
handwheel A the collar on spindle is brought in contact with seating G when the
shell can be parted at screwed part S, s & a new ring inserted at E and e.

COMPLETE SPECIFICATION.
Improvements in Water Gauges and Gauge Cocks.
1, FREDERIC WILLIAM PRIESTLEY PARKER of Sale in the County of Tanjil,
Victoria, Australia, Engineer 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:-
Figures refer to drawings left with Provisional Specification.
In Fig. 1 Sheet 1 the following letters indicate the parts of a gauge cock.
A is the handwheel; B is the discharge nozzle; C is the internal passage in
nozzle; D is the spindle; E is a ring of vulcanized fibre, celluvert fibre or metal;
F is a collar on spindle; G is a conical seating; H is a part of spindle which is
screwed and fluted; I is an annular space around the spindle; L is part of cock
which is screwed into boiler; O is a groove or flute in the screwed part of the
spindle forming the passage from the boiler; T is another groove for the same
purpose; S is the part of shell or body which is screwed, for removal when new
ring is required.
In Fig. 2. Sheet 1 is shown a gauge cock with the grooves formed in the shell.
a, is the hand wheel; b, is the discharge nozzle c, is the internal passage in
nozzle; d, is the spindle e, is the ring of vulcanized fibre, celluvert fibre or metal ;
f, is the collar on spindle; g, is the conical seating; h, is the screwed part of
spindle; i, is the annular space around the spindle; 1, is the part of cock which is
screwed into boiler; s, is the part of cock which is screwed for removal.

page_text: Fig. 3 is a section through lines 1-2 in Fig. 1 and shows the formation of
grooves T & O in the spindle D.
Fig. 4 is a section through lines 3-4 in Fig. 2 and shows the formation of
grooves or passages in the shell of cock at t, and o.
In Figs. 5 and 7. Sheet 2 is shown a water gauge the parts being indicated by
the following letters A. is the handwheel. B is the discharge nozzle, C is the
internal passage in nozzle D is the spindle. E is a ring of vulcanized fibre,
celluvert, fibre or metal, F is a collar on spindle G is a conical scating. H is a
part of spindle which is screwed and fluted, I is an annular space around the
spindle, L is part of cock which enters the boiler. O is a groove or flute in the
screwed part of the spindle forming the passage from the boiler, T is another
groove for the same purpose, S is the part of shell or body which is screwed for
the purpose of removal when a new ring at E is required.
W is a boss which is screwed into the shell at P.
Fig. 6. Sheet 2 is a section through lines 1-2 in Figs. 5 and 7, showing the
formation of grooves or passages T & O.
The working action is as follows. To open the cock or gauge for the discharge
of water or steam the handwheel A, or a has to be turned which causes the
collar For, to draw away from the rings E & e, when a clear passage is open
from the boiler to the discharge nozzle C & c, the water or steam passing through
the grooves T & O & t & o into the body or shell and from thence through the
annular space 1 & into the discharge nozzle C. To insert a new ring E & e the
wheel A has to be turned until one of the collars on spindle D, or d is tight against
conical seating G, or g, thus closing the passages to the boiler. The wheel A has
now to be removed from spindle D and part of the shell unscrewed at S, when it
can be drawn off & have new rings E, & e inserted. The shell is again replaced
& handwheel A refixed & spindle D rotated in opposite direction until collar F & ƒ
again comes in contact with ring E or e.
Having now particularly described & ascertained the nature of my said inven-
tion & in what manner the same is to be performed, I declare that what I
claim is :
1. The combination with a water gauge of a renewable ring seating such
as E & E Figs. 5 & 7 as described.
2. The combination with a water gauge of a grooved or fluted spindle such
as H & H. Figs. 5 & 7 as described.
3. The combination with a water gauge of a screwed removeable part such as
S & S Figs. 5 & 7 as described.
4. The combination with a gauge cock of a renewable seating ring such as E.
Fig. 1 & e. Fig. 2 as described.
5. The combination with a gauge cock of a grooved spindle such as H. Fig. 1 as
described.
6. The combination with a gauge cock of a screwed removeable part such
as S&s Figs. 1 & 2 as described.
