PROVISIONAL SPECIFICATION.
Improvements in Electric Indicators of Water Level.
I JOHN ERNEST HUTTON, of Solberge, Northallerton, in the County of York,
Gentleman, do hereby declare the nature of this invention to be as follows:-
My invention relates to apparatus arranged in a reservoir, tank, boiler, or other
vessel containing water, whereby, when the water attains one or other of certain
levels, an electrical indication is given at a distance.
For this purpose, I fix insulated in any convenient part of the vessel a number of
plates of metal at different heights and I connect each by a conducting wire to
one terminal of a battery. In front of these metal plates, but prevented from
coming in contact with them by insulating studs or frames slightly projecting
beyond the faces of the plates, I fix a conducting plate or bar which is connected
to the other terminal of the battery. In the conducting circuit I interpose any
suitable electrically worked visible or audible signal or both. When the water
reaches the level of any one of the insulated plates it operates as a conductor closing
the electric circuit and working the signal.
When the apparatus is applied to a metallic tank or vessel, the insulated plates
may be fixed very near to but not in contact with a side of the vessel which in
that case would act as the conducting plate or bar connected to one terminal of the
battery, the separate plates being connected to the other terminal.

Improvements in Electric Indicators of Water Level.
I, JOHN ERNEST HUTTON, of Solberge, Northallerton, in the County of York,
Gentleman, 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 :-
My invention relates to apparatus arranged in a reservoir, tank, boiler, or other
vessel containing water, whereby when the water attains one or other of certain
levels, an electrical indication is given at a distance.
For this purpose as shewn diagrammatically in the accompanying drawing I fix
insulated in any convenient part of the vessel V a number of plates P of metal at
different heights and I connect each by a conducting wire through a switch S to
one terminal of a battery. In front of the metal plates P, but prevented from
coming in contact with them by insulating studs or frames slightly projecting
beyond the faces of the plates, I fix a conducting plate or bar which may be the
7077

page_text: side W of the vessel itself when it is of metal which is connected through earth E
to the other terminal of the battery B. In the conducting circuit I interpose any
suitable electrically worked visible or audible signal or both. When the water reaches
the level of any one of the insulated plates P it operates as a conductor closing the
electric circuit and working the signal.
As shewn in the diagram the rubber of the switch S is connected to the battery
through a relay R, which operates through a second battery b and relay ra
ratchet wheel or similar device constituting an indicator I. When it is desired
to ascertain the level of the water the operator moves the rubber of the switch over
the several contacts; this causes the ratchet wheel to be moved a number of teeth
corresponding to the number of contacts of the switch that are put in circuit with
the battery by the water having attained the level of the plates connected to them.
Thus the number of divisions of a dial moved over by an index on the axis of the
ratchet wheel indicates which of the plates P has been reached by the water.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
An electric indicator of water level arranged and operating substantially as
described with reference to the drawing.
