Solicitors, 6, Lord Street, Liverpool, & 6, Bank Street, Manchester both in the
County of Lancaster & 323 High Holborn in the County of Middlesex, Patent
Agent, do hereby declare the nature of this invention to be as follows:-
The improvements forming the subject of the present invention have for their
object to allow the working or the standing still of all the valves, say, of a pump,
to be ascertained, the attention of the ear or eye being drawn thereto, and in
particular the working or otherwise of the supply valve of boilers, so that the
attendant can at any moment reliably ascertain the state of action of these parts,
the accurate working of which is the best guarantee of safety.
It should not be lost sight of that the working parts of a pump or of a valve box
cannot in a sense be under control seeing that they are hidden, they may therefore
cease working without giving any warning which would result in serious conse-
quences. The application of this invention, by removing this uncertainty as to the
working, or not, of the feed apparatus of steam boilers for instance, does away with
the principal difficulty always found when using such boilers.
An apparatus or device constructed according to this invention is composed of a
hollow metallic tube, in which a movable rod is situated, having at its lower end a
head (or shoulder), forming a valve, and at its upper end a movable index. Above
this index there is a spring having two metallic washers. Two electric terminals
are fixed in an insulated piece and carry circuit wires. A glass tube is tightly
fixed by means of two washers and allows the movement of the index to be seen.
Every valve, when in action, has a vertical alternating movement on its seat,
invisible to the exterior.
By means of these improvements this movement is indicated as follows:-
1st. By an electric bell placed at some suitable place and capable of being heard
by everybody. The working of the bell is effected by the two terminals (fixed in
the insulated piece and carrying the circuit wires as aforesaid) being brought into
contact or circuit by the intermediation of the metallic washers which are attached
to the spring and rest loosely on the index of the movable rod, the latter being
placed loosely on the head of the valve, the movement of which it is desired to
indicate, and will follow all the movements of the latter.
The distance which separates the washer of the apparatus or device from the
terminals being as small as may be desired, it follows therefrom that on the slightest
movement of the valve, contact takes place, and continues up to the moment when
the said valve returns once more to its seat. The duration of the contact is
ensured by the employment of the spring which allows the movable rod to move
freely.
2nd. The movement of the valve is rendered still more apparent by providing
an opening in the cover of the index, and by placing therein the glass tube afore-
The index moves inside this glass tube and its movements are visible through
the transparency of the glass.

In both cases the lower part of the movable rod has a head piece or shoulder
forming a valve and intended to prevent the passage of the fluid, say of the water

the apparatus or device.
In fitting the apparatus or device it is sufficient to place it on the axis of
the lid or stopper of the valve box, such having been first bored to receive the
movable rod.
In the course of working, the body of the indicating apparatus or device forms
an air reservoir and in such a way that the movable parts are always visible in the
tube, even when the feed is a highly coloured liquid.

COMPLETE SPECIFICATION.
Improvements in or relating to Apparatus or Devices for Indicating
the Working or otherwise of Valves, more especially of Pump or
Supply Valves.
A communication from abroad by ANDRE GUASCO and ANGE CHUSIN, both of
16, Rue de Bausset, Marseilles, in the Department of Bouches du Rhône, in
the Republic of France, Engineer and Builder respectively.
I, GEORGE CECIL DYMOND, M. Inst. M.E., of the Agency for Foreign
Patent Solicitors, 6 Lord Street, Liverpool and 6 Bank Street, Manchester,
both in the County of Lancaster, and 323 High Holborn in the County of
Middlesex, Patent Agent, 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:-
The improvements forming the subject of the present invention have for their
object to allow the attention of the car or eye being drawn to the working or the
standing still of all the valves, say of a pump, and in particular the working or
otherwise of the supply valve of boilers, so that the attendant can at any moment
reliably ascertain the state of action of these parts, the accurate working of which
is the best guarantee of safety.
It should not be lost sight of that the working parts of a pump or of a valve box
cannot in a sense be under control seeing that they are hidden, they may therefore
cease working without giving any warning and this would result in serious conse-
quences. The application of this invention, by removing this uncertainty as to the
working, or not, of the feed apparatus of steam boilers for instance, does away with
the principal difficulty always found when using such boilers.
This invention will be the more clearly understood by reference being made to
the accompanying sheet of drawings, in which,
Figure 1 is a vertical section of the valve indicating apparatus attached to a
valve box, and
Figure 2 shows a side view of the indicating apparatus.
The lettering of similar parts in both figures is identical.
In Figure 1, T is a hollow metallic tube in which a movable rod a is situated,
having at its lower end a head (or shoulder) c forming a valve, and at its upper end
a movable indicator b. Above this indicator there is a spring K having two metallic
washers II. Two electric terminals tt' are fixed in an insulated piece M and
carry circuit wires r r. A glass tube d is tightly fixed by means of two washers g g
and allows the movement of the indicator b to be seen.
Every valve, when in action, has a vertical alternating movement on its seat
exteriorly invisible.
By means of these improvements this movement is indicated as follows-
1st. By an electric bell placed at some suitable place and capable of being heard
by everybody. The working of the bell is effected by the two terminals t 1 (fixed

page_text: in the insulated piece M and carrying the circuit wires as aforesaid) being
brought into contact or circuit by the intermediation of the metallic washer I which
is attached to the spring K. This spring K is loosely supported on the indicator b
of the movable rod a. This rod a is placed loosely on the head of the valve e the
movement of which it is desired to indicate, and will partake in all the movements
of the latter.
The distance which separates the washer I of the apparatus or device from the
terminals & t¹ being as small as may be desired, it follows therefrom that on the
slightest movement of the valve, contact takes place, and continues up to the moment
when the said valve returns once more to its seat. The duration of the contact is
ensured by the employment of the spring K which allows the movable rod a to
move freely.
2nd. The movement of the valve is rendered still more apparent by providing an
opening in the cover of the indicator, and by placing therein the glass tube d afore-
said. The indicator bmoves inside this glass tube and its movements are visible
through the glass.
In both cases the lower part of the movable rod a has a head piece or shoulder c
hereinbefore referred to as a valve and intended to prevent the passage of the fluid,
say
of the water of the boiler, to the exterior, in case the glass breaks or of other
injury to the apparatus or device.
In fitting the apparatus or device it is sufficient to place it on the axis of the
lid or stopper of the valve box V such having been first bored to receive the
movable rod.
In the course of working, the body of the indicating apparatus or device forms
an air reservoir and in such a way that the movable parts are always visible in the
tube even when the feed is a highly coloured liquid.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed, as communicated to me by my
foreign correspondents, I declare that what I claim is :-
1. The improvements in or relating to apparatus or devices for the object
specified, which consist in the employment in such kind of apparatus of a rod a in
connection with and capable of following all the movements of the valve and at the
same time of actuating an indicator and washer I, the latter for the purpose
of completing an electric circuit all substantially as and for the purposes
described.
2. In an apparatus or device such as hereinbefore described, the employment of
a spring K attached to the indicator b and the circuit closing washer I substantially
as and for the purpose described.
3. The general arrangement and construction of apparatus or devices for
indicating the working or otherwise of valves substantially as hereinbefore
specified.
