I do hereby declare the nature of this invention to be as follows :—
A circular metal vessel with a closely fitting water-tight cover, revolving on an
axle between two upright supports. The interior is divided into three chambers,
the lower one which I call being larger than the upper ones which I call A
and B. A contains a weight, and is partially balanced by the chamber B when full
of water. In the partition between B and C a tap regulated from the rim of the
vessel allows the water in B to pass into C at any degree of speed. In the same
division is fixed a valve which opens upwards so that when the vessel is inverted the
water in C returns into B. A small tube also in this division allows air to pass
upwards from C to the upper part of B. When the water in B is exhausted the
weighted portion of the vessel A falls down to the lowest point.
Between the same uprights that support the axle of the vessel a small pulley
wheel also revolves connected by a cord passing round the circumference of both.
The axle of the pulley is prolonged so as to reach the spindle of the lamp which it
clasps by a thumb screw. The fall of A. to the lower side causes the pulley wheel
to revolve and instantly extinguishes the lamp. By bringing C uppermost B will
be refilled and ready for use again.
Dated this 31st day of August 1894.

HENRY JUSTINIAN NEWCOME Shenley, Herts, Clergyman, 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 consists of a circular water tight vessel (A-a section of which is
shown in the drawing Fig. 2) revolving on an axle, and so divided internally into
separate chambers that a weight on one side (B) is counterbalanced by a similar
weight of water on the opposite side (C). This water passes by gravitation through
a tap (D) either slowly or rapidly as may be desired to the opposite side of the
vessel (E) thereby destroying the equilibrium, and causing the weighted side to
fall at any desired or required time. Above the vessel is fixed a wheel Fig. 1 (F)
the axle of which (G) projects so as to reach the lamp, the button of which (H) it
clasps by a thumb screw arrangement. On the same spindle, a larger pulley (I) is
fixed which is actuated by a weight or spring. A stud K projects from the rim of
the central pulley (F) which when wound up is held by a trigger (L) the lower end
of which is struck by a projection (M) on the rim of the revolving vessel, and
releasing the weight or spring instantly extinguishes the lamp. The water is
replaced by turning the vessel half over from right to left, when it passes through
a valve (N) which falls open, and closes again when returned to its original position.

water is passing down.
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
1. The obtaining automatic action by the transfer of water from one chamber of
a vessel to the opposite.
