page_text: We, JAMES ANDERSON, of 1, Smith Street, Hillhead, Portioner, and CHARLES
DICKIE, of 195, Stobcross Street, Brass Finisher, both in the City of Glasgow, do
hereby declare the nature of this invention to be as. follows:-
This invention, which relates to valves and cocks for steam, water and other
fluids, has for its object the provision of simple and inexpensive packing for
rendering them fluid tight.
The valves or cocks are or may be of the kind which are carried upon a screw
threaded or other stem and close against a seat around an orifice in a web formed
in the valve or cock casing through which orifice the steam or water passes.
To prevent leakage we form preferably on the outlet side of the web a flange or
rim around the orifice in which a packing ring of asbestos or like material or a
metallic packing is placed, and in the underside of the casing we form an orifice
through which is inserted a hollow plug having a through-way for the passage
of the steam or water which plug bears against the packing so as to press it
against the valve around the valve seat. Under the hollow plug a second packing
ring is placed and a screw threaded plug is fitted in the orifice and turned until
it presses up the outer packing and the hollow plug to make the whole fluid tight.

We, JAMES ANDERSON, of 1, Smith Street, Hillhead, Portioner, and CIFARLES
DICKIE, of 195, Stobcross Street, Brass Finisher, both in the City of Glasgow, 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:-
This invention, which relates to valves and cocks for steam, water and other
fluids, has for its object the provision of simple and inexpensive packing for
rendering them fluid tight.
The invention is illustrated by the accompanying drawing.
The valves or cocks A are or may be of the kind which are carried upon a

page_text: screw threaded or other stem B and close against a seat around an orifice C in a
web D¹ formed in the valve or cock casing D through which orifice C the steam
or water passes. To prevent leakage we form preferably on the outlet side of the
web D a flange or rim Da around the orifice C in which rim a packing ring G
of asbestos or like material or a metallic packing is placed, and in the underside
of the valve casing D we form an orifice E through which is inserted a hollow
plug F having a throughway F¹ for the passage of the steam or water, which
plug F bears against the packing ring G so as to press it against the underside of
the web in which the valve seat orifice C is formed, and also to press tightly
around the valve A. Under the hollow plug a second packing ring or disc H
is placed and a screw threaded plug I is fitted in the orifice E and turned until it
presses up the outer packing disc H, the hollow plug F and the packing ring G
to make the whole fluid tight.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:
-
1. A valve or cock for steam, water or other fluids, the parts of which are con-
structed and combined substantially as described.
2. In a valve or cock for steam, water or other fluids, the combination of a
packing ring fitted inside a rim on the outlet side of the valve seat, a hollow
plug bearing on said packing ring and having a throughway for the passage of
the steam or fluid, a second packing ring or disc placed between the hollow plug
and a screwed plug entering a screwed orifice in the valve or cock casing, said
screwed plug being adapted to press the hollow plug upwards and consequently
press the packing ring against the underside of the web in which the valve seat
orifice is formed and also press it around the valve for the purpose of making
the whole fluid tight.
