We, JAMES LEE NORTON, of Belle Sauvage Yard, Ludgate Hill, in the
City of London, and FREDERICK LUDOVICUS HENRI WILLIAM BUNGER, of
No. 17, Southampton Buildings, Chancery Lane, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN APPARATUS FOR DIS-
CHARGING THE WATER RESULTING FROM CONDENSED STEAM FROM APPARATUS WHERE
STEAM IS EMPLOYED," to be as follows
-
This Invention has for its object improvements in apparatus for discharging
the water resulting from condensed steam from apparatus where steam is
employed, and is applicable to apparatus acting in the manner described in
the Specification of a Patent granted to Frederick Ludovicus Henri William
Bunger, dated 27th day of October 1862 (No. 2890).
In constructing apparatus according to the present Invention it is preferred
that the vessel which receives and discharges the condensed water should be
spherical, and made in two halves, but this form is not essential. The upper
half of this vessel has an inlet on one side, where it is connected by a suitable
pipe to the apparatus wherein steam is employed. Through the upper part
of this vessel is a passage, and when necessary a stuffing box through which
a spindle or rod is introduced, and provision is made for raising and lowering
such rod or spindle in order that the distance its lower end descends into
vessel may be adjusted from the outside by screw nuts or otherwise. At the

page_text: lower end of this rod or spindle is fixed a hollow vessel, by preference of a
cylindrical form, the upper and lower ends of which inner vessel are each
formed with a flexible disc of sheet metal having concentric corrugations.
When the apparatus is in use this cylindrical vessel is full of water, which is
introduced through a hole which is closed by a screw plug. The lower end
of the spindle or rod above mentioned is fixed to the centre of the upper disc.
Above this inner vessel on the same spindle or rod is a guard to prevent the
water flowing on to the upper disc of the cylindrical vessel. To the centre of
the lower disc is fixed the upper end of a valve spindle, at the lower end of
which is fixed a valve; this valve closes the outlet at the bottom of the
spherical vessel when steam pervades the interior of such vessel by reason of
the heat of the steam causing the water contained in the cylindrical vessel
suspended within the spherical vessel to expand, but such valve opens when
the spherical vessel becomes charged with condensed water, so as to cool the
water contained in the inuer cylindal vessel. Below the cylindrical vessel
is applied a horizontal partition of wire gauze to prevent dirt or other matter
getting to the valve. At the bottom of the spherical vessel a waste pipe is
fixed at the outlet in order to convey away the condensed water. By thus
arranging the apparatus so as to adjust the valve by the upper spindle or rod
a very nice adjustment may with facility be obtained, whilst it admits of the
waste pipe being used to convey away the condensed water to any desired
distance.
In place of the two corrugated disks afore-named forming part of the inner
vessel, a corrugated metallic tube closed at each end may be used to form the
inner vessel, to the top portion of which the adjusting rod is fixed, and to the
lower the valve.
