This style of embossing the dial was
adopted in 1898 and was used for about 50 years, when the company had
to diversify and became known as CHADBURN (LIVERPOOL) Ltd.
Look out for the most commonly used 'Oval'
shaped company name with LIVERPOOL
in large capitals underneath.! If 'London' has
been added, and sometimes a picture of a
'sailing ship' or an 'anchor' then it is a
replica production, and not a GENUINE Chadburn !!

DUPLEX SIGNAL LAMP INDICATOR ON THE
CAPTAIN’S BRIDGE OF THE “MAURETANIA” Which notifies the failure of any
of the ship’s navigating lights and sounds a horn to warn the
officers. With Electric
Lamp telegraphs, these sophisticated Ocean Liners passed on the
chosen 'Order ' to this central
panel. Below right is a young Cadet
probably only asked by the photographer of 1908 to 'Put his
hand' on the Chadburn telegraph lever.!!

TELEGRAPH ON THE BRIDGE OF THE
CUNARD MAIL STEAMER “MAURETANIA” - LEVER
is in 'STOP' position. This vessel was
built by Swan-Hunter and launched in 1906. It had many
advanced
features, later incorporated into the 'Titanic'!

THE SINGLE LEVER ON THE BRIDGE OF THE
“MAURETANIA” The movement of which closes the forty water-tight doors
which insure the safety of the ship, and gives electrical warning of
the failure of any particular door. To the right of picture
is Chadburns telegraph of the
Admiralty type, using rod gearing to send signals to Engine Room.

The ship's telegraph with vertical handle
only, including dial, or dials if twin screw ship, relied on chain and
wire to the engine room. They are shown in our pictures. The Admiralty,
or MoD Naval, insisted on rod gearing with universal joint since they
calculated that wire stretched by as much as 14%. The relative
positions sent to the engineers below had to have the horizontal dial
with a vertical wheel hand, and that type of telegraph was adopted for
all Warships. (incl. the Royal Yacht 'Britannia'). This type of
instrument is rarely seen with the exception of treasures found by
divers, in the past.
The wording (Ship) Telegraphs Coy Ltd. Was necessary in
Chadburns name, since Marconi (Wireless) Telegraph was made available
to send messages to and from ships/ashore stations! This took place at
the same time.

PLEASE NOTE: the illustration
above is a Chadburn where the
handwheel has to 'go one revolution' to move the
pointer on the
horizontal scale - one Order, (i..e. here
in this picture only, shown below the brass
pedestal ) - these telegraph systems are very
rare, and the Rod Gearing with Universal
joints fitted inside were
elaborate and costly. However, it ensured perfect
transmission to
the Engrine room Receiver t'gh.

(These 3 photographs
of the famous Cunarder are from unknown
archives. Also fitted to sister ship,
'LUSITANIA')
Other photographs are from company
records, and trademark on top left, re-created
in 1990 for use on Christmas cards, etc.
The *Chain and wire* type of telegraph
system with the specific wording : FULL
AHEAD - plus 2, 3 or 4 Orders to
the left and right of the TOP position with
ASTERN - became Chadburn 's very
clever interpretation of the most
appropriate Commands !! and we go back to the
1860's. Just as Samuel Morse invented his ... -
- - system! Both Chadburn and Morse
became legendary figures.
In the same manner, Marconi achieved world acclaim with his
unique
wireless telegraph method of using the 'Hammer'.!
NOTE: the author of these pages is Swedish by
origin and admires the way different Lingustic
skills focus in on ENGLISH as a
truly UNIVERSAL LANGUAGE.
