BATTERY RINGING
TELEPHONE
RAILWAY TYPE
WALL PATTERN
 No. 40305
Produced for Railway work, this Battery Ringing Telephone is preferred by a
large number of people.
After long and careful study, the above set
was designed and will be found to be efficient, strong, and simple in
construction. A large number of this type of telephone have been installed
by two of the large Railway Companies in the United Kingdom and are
rendering highly efficient service.
The framework is of Walnut and
can be fitted with the "Delville" Transmitter, the Solid-back Transmitter on
a plate or bracket, or the Transmitter mounted inside the set.
A
"Watch" or "Bell" pattern Receivers can be fitted.
The principal
points regarding the actual construction of the set are:-
- All wiring is run in such a manner that it can be easily traced, at
the same time it is not unduly exposed.
- All terminals are large and can be screwed and unscrewed without the
aid of tools.
- The switch-hook is of our usual type, i.e., it is easily removable
for transit, is fixed in position by merely pushing it in place, and it
cannot be removed once it is in place, without opening the set.
The switch itself is self-contained and can be removed from the set by
unscrewing, so that if the switch is damaged, it can be removed and
replaced by a new one, cheaply and quickly, even by one not familiar
with telephone work.
- The Induction Coil has no wires brought out for terminals, so it is
not liable to broken connections. The four screws which hold the coil in
place also make the necessary connections, and the coil cannot be
connected with the primary and secondary coil reversed.
- All connections are made by means of wires, not through the hinges.
Dimensions - 11.5" x 7.25" x 7".
Weight - 61b.
