PROVISIONAL SPECIFICATION.
Improvements in or connected with Electric-bell Pushes.
We, JAMES WITHERS CREASEY of 2 Fife Road Kingston, Surrey, Sign
Writer and THOMAS WILLIAM BREACH of Wantage House Strawberry Hill,
Middlesex, no occupation, do hereby declare the nature of this invention to be as
follows:-
The user of the ordinary push of an electric bell has no means of ascertaining
whether the bell has operated and the object of our invention is to obviate this
defect by providing an indicator for informing the user of the push that the bell
has been sounded, and in carrying out our invention we proceed in or in about the
following manner.
On a suitable base we provide two springs as in the ordinary bell push one of
them being connected with a wire of the battery and the other furnished with a*
thumb piece for pressing the two springs into contact with each other. Attached
to the base in any suitable manner we provide two coils of covered wire having
suspended between them a needle (as in the case of an ordinary telegraphic
apparatus). One end of the wire forming these coils is attached to a terminal also
provided on the base and the other end is connected with the second of the two
springs. From the terminal another wire passes to the electric bell. The whole
is covered in by a suitable cover having an opening over the needle. The needle
is furnished with a disc or discs or the like, colored marked with a name, word,
number or otherwise rendered distinguishable and so arranged that when the
circuit is completed by pressing the springs into contact and the needle deflected,
the distinguishing sign on it will appear at the opening in the cover. Any
other means of completing the circuit than by the use of two springs may be
employed.

COMI LEIE SIECIFICATION.
Improvements in or connected with Electric-bell Pushes.
We, JAMES WITHERS CREASEY of 2, Fife Road, Kingston, Surrey, Sign
Writer and THOMAS WILLIAM BREACH of Wantage House, Strawberry Hill,
Middlesex, no occupation, 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 user of the ordinary push of an electric bell has no means of ascertaining
whether the bell has operated and the object of our invention is to obviate this
defeet by providing an indicator for informing the user of the push that the bell
has been sounded, and in carrying out our invention we proceed in or in about the
following manner.
---
On a suitable base board we provide two springs as in the ordinary bell push
one of them being connected with one terminal of the bell and the other furnished
27

page_text: with a finger piece for pressing the two springs into contact with each other and
completing the circuit. Attached to the base board in any suitable manner we
provide an electric magnet (preferably a bar one) one end of the coil of which is
attached to the spring under the one furnished with the finger piece, and the other
end to a terminal with which is also connected one pole of the battery, the other
pole being connected the wire leading into the second terminal of the bell. The
above mentioned parts are enclosed by a cover having in it a hole to allow the
finger piece to project through in the usual manner. In the cover and so situated
as to come immediately over the electric-magnet we provide an opening passing
right through the cover. In this opening we fix a small (preferably) circular
metallic box having a glass top and a glass bottom between which swings a
magnetic needle, the said needle being attached to a light spindle the ends of
which work in small cavities provided for the purpose in the top and bottom of the
box. The needle has attached to it a dise having on it a star or other device and
on the glass top of the box may be another star or device of contrasting color to
that on the needle disc. The box is put in the opening so that the glass top
with the star or like on it is outside and can be seen from the front of the cover.
Instead of a star or device the disc may be colored, marked with a name, word,
number or otherwise rendered distinguishable. When the circuit is completed by
pressing the springs in contact, the needle will be deflected and rotate the disc and
thus advise the operator that the bell has rung. The invention is applicable to
any other kind of bell push besides those in which two springs are employed as
above mentioned. The disc may also be coated in any desired manner with
luminous paint, composition, or like substance.
In order to more fully explain our invention we make reference to the
accompanying sheet of drawings on which
Fig. 1 is a front view of base board and fittings with cover removed.

Fig. 3 a section through the needle box of Fig. 1.
a base board: 6 the spring carrying the finger piece c: d the bell: e the battery:
the magnet one end of the coil on which is attached to the under spring" and
the other end to the terminal g which is connected to one pole of e: the other pole
being connected by wire h with the second terminal of d: i is the needle box,
between the glass back and front j and k of which is suspended a magnetic needle
carrying a disc or equivalent m as already mentioned.
Considerable variation in the shape, configuration and disposition of the various
parts can be made without departing from the spirit of our invention, and we do
not therefore confine ourselves to precise details as described in the above
specification or exemplified in the accompanying drawings.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is:
The combination with electric bell pushes of an electric magnet which on the
push being put in action causes the deflection of a magnetic needle bearing a disc
coated or not with luminous paint or the like and having thereon a distinguishing
device or equivalent whereby is indicated to the user that the bell has rung, the
whole provided for and operating substantially as described in the above
specification, & exemplified in the accompanying drawings.
