AN IMPROVED PACKING FOR THE GLASS TUBES OF WATER GAUGES
Year: 1885

We HENRY HALLWORTH of N° 86 Manchester Road, Engineer, and JAMES
LIGHTFOOT SHORROCK of 139 Manchester Road Mechanic both of Accrington in
the County of Lancaster do hereby declare the nature of my invention for AN
IMPROVED PACKING FOR THE GLASS TUBES OF WATER GAUGES" to be as follows:-
This invention relates to the means employed for fixing and packing (in a water
and steam tight manner) the glass tubes in the water gauges employed for indicating
the height of the water or other liquid in steam boilers or other vessels.
Our invention consists principally in the use for this purpose of a conical lipped
ring of india-rubber which is fitted onto the glass tube and is held in its place by
means of a screwed metal cap.
The interior of the said ring is made of a suitable diameter to fit the outside of
the glass tube upon which it is placed with its tipped edge towards the end of the
said tube. The said ring is made with a flange which rests on the edge of the
socket or short tube of the tap in which the glass tube is to be fixed, the outside of
which socket is formed with a screw thread.
We provide also a metal cap screwed on the inside so as to fit onto the screwed
socket and having through the centre a hole rather larger than the outside of the
glass tube; also a metal washer fitting loosely inside the said metal cap.
In fixing the lower end of the tube the india rubber lipped ring is first placed on
the end of the glass tube with its lipped edge towards the lower end thereof, and it
is then placed in a socket of the tap with the flange of the ring resting on the top
of the socket. The metal washer is then placed over the india rubber ring, and
the metal cap is brought down over it, and screwed onto the top of the socket
thereby compressing the india rubber ring and causing it to hold and pack the
glass tube in a perfectly water and air-tight manner; at the same time that the
glass is not held too rigidly and certain amount of accommodation and freedom
for expansion and contraction is permitted.
To fix and pack the upper end of the glass tube the same parts are used but
reversed in position.

We HENRY HALLWORTH of 86 Manchester Road, Engineer, and JAMES
LIGHTFOOT SHORROCK of 139 Manchester Road, Mechanic, both of Accrington
in the County of Lancaster do hereby declare the nature of our invention for
AN IMPROVED PACKING FOR THE GLASS TUBES OF 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 the means employed for fixing and packing (in a water
and steam tight manner) the glass tubes in the water gauges employed for indicating
the height of the water or other liquid in steam boilers or other vessels.
Our invention consists principally in the use for this purpose of a conical lipped 1
ring of india rubber or other suitable substance or composition which is fitted onto
the glass tube and is held in its place by means of a screwed metal cap, either with
or without a metallic washer intervening.
Such being the nature and object of our said invention we will now proceed to
describe in detail the manner in which the same is to be or may be performed or
carried into practical effect and in order that the same may be clearly understood
we have annexed hereunto a drawing illustrative thereof and have marked the
same with letters of reference corresponding with those in the following explanation
thereof.
In the drawing Fig. 1. represents a full size section of so much of a water gauge
as is necessary to illustrate our invention, a, a being the glass tube, 6, 6 the sockets
at top and bottom into which it is to be fixed, c, c the india rubber lipped ring
d, d the metallic washer and e, e the screwed metal cap.
The interior of the said india rubber lipped ring c, c is made also conical as
shown in section at Fig. 2 being of a suitable diameter to fit the outside of the
glass tube a a upon which it is placed with its lipped edge towards the end of
the said tube so that the steam and water will surround it and press its lipped
edge against the glass tube so as to form a tight joint.
The said ring c, c is made preferably with a flange which rests on the edge of
the socket b b or short tube of the tap in which the glass tube a, a is to be fixed,
the outside of which socket is formed with a screw thread; or the ring c, c may be
made without a flange as shown at Fig. 3. The metal cap e, e is screwed on the
inside so as to fit onto the screwed socket b, b and having through the centre a hole
rather larger than the outside of the glass tube a, a the metal washer d, d fitting
loosely inside the said metal cap.
A plain metal washer may be employed, but for altering an existing gauge the
ordinary gland of the stuffing box may be reversed and utilized for the said
purpose as shown at d, d on the drawing. In fixing the lower end of the tube a, a
the india rubber lipped ring c, c is first placed on the end of the glass tube a, a with
its lipped edge towards the lower end thereof and it is then placed in the socket of
the tap with the flange of the ring c, c resting on the top of the socket b, b.
The metal washer å, d is then placed over the india rubber flange of the ring c, c
and the metal cap e, e is brought down over it, and screwed onto the top of the

page_text: socket b, b thereby fixing the india rubber ring c, c and holding and packing the
glass tube a, a; and the pressure of the steam or water on its lipped edge forms a
perfectly water and steam tight joint; at the same time that the glass is not beld
too rigidly, and a certain amount of accommodation and freedom for expansion and
contraction is permitted.
To fix and pack the upper end of the glass tube the same parts are used but
reversed in position as shown on the drawing.
Having now particularly described and ascertained the nature and object of our
said invention, and in what manner the same is to be performed we declare that
what we claim is
The improved packing for the glass tubes of water gauges consisting in the
combination of a conical lipped ring of india rubber or other suitable material or
composition with a screwed metal cap, and either with or without a metallic
washer substantially as hereinbefore set forth and described and illustrated by the
drawings annexed.
