We, SIEMENS BROTHERS & CO., LIMITED, of 12, Queen Anne's Gate, Westminster,
in the County of London, Electrical Engineers, and ALEXANDER SELGIUS SCHLOEMER,
of 25, Priolo Road, Old Charlton, Kent, Electrical Engineer, do hereby declare the
nature of this invention to be as follows:--
This invention consists in combining with a telephone a vibrator of known kind
thus producing an instrument by which signals can be transmitted by the same line
as that for the telephone, the whole instrument being compact and light so that it is
well suited for military and such like uses.
A convenient form of the instrument is shewn by the accompanying drawings.
Fig. 1 is a perspective view, Fig. 2 is a diagram of the electrical connections and
Fig. 3 shews a modification of the keys.
To a cylindrical casing c, which can be held in the hand, are attached at the one
end a telephone receiver and at the other end a transmitter t and a vibrator v. On
the side of the casing c are keys, the one k for making contact for the vibrator cir-
cuit and the other m for making contact for the transmitting circuit either of which
can be worked by the hand which holds the casing. In the diagram Fig. 2, b indicates
the battery, the line, and e earth. On pressing the key & the circuit is established from
one pole of the battery to the vibrating tongue when in the back position and thence
to earth, while the other pole of the battery is connected to earth through the coils
of the vibrator magnet. On pressing the key m, the pole of the battery is put in
circuit to earth e through the transmitter. The other pole of the battery is always in
circuit with the line through the receiver r. Instead of two separate keys k and m
a single key pivotted in the middle, as shewn in Fig. 3 may be employed to make
the one contact or the other according as the one end or the other is pressed.
In many cases the telephone transmitter may be dispensed with, the instrument
being thus simplified. Also, the vibrator, instead of being placed outside the casing
as in Fig. 1 may be placed inside, and may be arranged either at the lower end of
the casing or at the top close to the telephone receiver. In this case the electro-
magnet of the telephone receiver may serve also for the vibrator.

We, SIEMENS BROTHERS & CO., LIMITED, of 12, Queen Anne's Gate, Westminster,

of 25, Priolo Road, Old Charlton, Kent, Electrical Engineer, do hereby declare the
Q71

page_text: 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 in combining with a telephone a vibrator of known kind
thus producing an instrument by which signals can be transmitted by the same line
as that for the telephone, the whole instrument being compact and light so that it is
well suited for military and such like uses.
A convenient form of the instrument is shewn by the drawings accompanying
our Provisional Specification and the additional drawing Fig. 4 filed herewith.
Fig. 1 is a perspective view, Fig. 2 is a diagram of the electrical connections and
Fig. 3 shews a modification of the keys. Fig. 4 shews a modified arrangement of
the connections.
To a cylindrical casing c, which can be held in the hand, are attached at the one
end a telephone receiver r and at the other end a transmitter t and a vibrator v. On
the side of the casing c are keys, the one k for making contact for the vibrator
circuit and the other m for making contact for the transmitting circuit either of which
can be worked by the hand which holds the casing. In the diagram Fig. 2, 6 indi-
cates the battery, the line, and earth. On pressing the key k the circuit is established
from one pole of the battery to the vibrating tongue when in the back position and
thence to earth, while the other pole of the battery is connected to earth through the
coils of the vibrator magnet. On pressing the key m, the pole of the battery is put
in circuit to earth e through the transmitter. The other pole of the battery is always
in circuit with the line through the receiver r.
In Fig.
the connections are such
that when the key is pressed, one pole of the battery b is connected through
the vibrating tongue in its back position to the metallic casing p p' and thence
through the transmitter t to earth e. When the key m is pressed the same pole is
connected to the casing and thence by p through the coils of the vibrator magnet v
to the other pole which is always connected through the receiver to line l. Instead
of two separate keys k and m a single key pivotted in the middle, as shewn in Fig. 3
may be employed to make the one contact or the other according as the one end or the
other is pressed.
In many cases the telephone transmitter may be dispe: 1 with, the instrument
being thus simplified. Also the vibrator, instead of being placed outside the casing
as in Fig. 1 may be placed inside, and may be arranged either at the lower end of the
casing or at the top close to the telephone receiver. In this case the electromagnet
of the telephone receiver may serve also for the vibrator.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:-
--
The combination of a telephone transmitter and receiver with a vibrator in one
instrument suited to be held in the hand and provided with contact keys sub-
stantially as described with reference to the drawings.
