PROVISIONAL SPECIFICATION.
Improvements in Steam or Water Valves, the said Improvements
being also applicable to Water Gauges.
1, WALTER LEES, of Bedford Street Works, Halifax, in the County of York,
Brassfounder and Finisher, do hereby declare the nature of this invention to be
as follows:-
In constructing a valve according to my invention, the spindle is not fastened
to the band wheel or lever as is customary, but it is held to the said hand wheel or
lever by a nut.
The hand wheel or lever is made with an internally screwed socket working over
a screwed bush so that when the hand wheel is operated in one direction the
spindle is raised vertically and the valve opened, but on turning the hand wheel or
lever in the opposite direction the spindle is lowered to close the valve, but the
spindle has no rotary motion only an up and down motion.
In consequence of the spindle not rotating the packing in the gland will wear
much longer and when the valve or seating becomes worn the spindle of my
improved valve can be rotated by turning the nut on the head of the spindle thus
the seating and valve can be re-ground whilst the valve is in action. At a point
above the valve of the spindle I form a shoulder made in the form of a valve so
that when the valve proper is fully open, the upper valve is binding against a
seating below the gland thereby absolutely preventing steam or water getting to
the said gland.
In practice it is often found that the hand wheel or lever becomes overheated
in consequence of being in close proximity to steam. To overcome this overheating
of the hand wheel or lever I make the said lever hollow, but open at both ends to
allow the passage of atmospheric air to keep the same cool.

COMPLETE SPECIFICATION.
Improvements in Steam or Water Valves, the said Improvements
being also applicable to Water Gauges.
1, WALTER LEES, of Bedford Street Works, Halifax, in the County of York,
Brassfounder and Finisher, 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 :-
In constructing a valve according to my invention, the spindle is not fastened to
the hand wheel or lever as is customary, but it is held to the said hand wheel or
lever by a nut.
In order that my invention may be definitely understood, I will refer to the
annexed sheet of drawings illustrative thereof, wherein :-
Fig. 1 is a vertical section of a wheel valve constructed according to my
invention. A is the valve casing or box and B the vertical valve spindle.
[Price 821

page_text: The hand wheel C is not secured to the top of the spindle as is customary
but it is held to the said hand wheel by a nut D which is screwed down upon a
shoulder a formed near the top of the said spindle. The hand wheel or lever C is
made with an internal screwed socket E working over a screwed bush F so that
when the hand wheel is operated in one direction, the spindle B is raised vertically
and the valve opened thereby, but on turning the hand wheel or lever in the
opposite direction, the spindle is lowered to close the valve, this being effected by
means of a shoulder t, which nicely fits a round hole made in the hand wheel, it
being evident that the spindle having no rotary motion but only an upward and
downward motion.
Near the bottom of the valve spindle B I form a shoulder c made in the form
of a valve so that when the valve proper is fully opened the upper valve c is binding
against a seating d thereby absolutely preventing steam or water getting to packing
and gland H.
In consequence of the spindle not rotating, the packing in the gland will wear
much longer, and when the valve or seating becomes worn the spindle of my
improved valve can be rotated by turning the nut D on the bead of the spindle,
thus the seating and valve can be re-ground whilst the valve is in action.
Fig. 1 of the drawings illustrates an ordinary wheel valve, but Fig. 2 shews the
application of my improvement to a similar valve applied to a water gauge where A
is the body of the valve, screwed part I being attached to that part of the gauge
which receives the glass tube not shewn.
In practice it is found that the hand wheel or lever in connection with the
valve becomes overheated in consequence of being in close proximity to the
steam. To overcome this overheating of the hand wheel or lever I make the said
lever hollow as shewn at J but open at both ends to allow the passage of
atmospheric air to keep the same cool.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
Firstly. In steam or water valves, the combination of hand wheel C, nut D,
shoulders a, b, and internal screwed socket E, all operating in the manner
described and shewn in the drawings.
Secondly. Forming valve wheels or levers hollow as at J in Fig. 2 for keeping
down the temperature of the said wheel or lever as herein described.
