IMPROVEMENTS IN SIGNALIZING ON RAILWAYS, AND IN THE APPARATUS USED THEREIN
Year: 1853

page_text: LETTERS PATENT to Henry Henson Henson and William Frederick
Henson, both of Hampstead, in the County of Middlesex, Civil
Engineers, for the Invention of "IMPROVEMENTS IN SIGNALIZING
ON RAILWAYS, AND IN THE APPARATUS USED THEREIN."
...!
Sealed the 16th March 1853, and dated the 17th January 1853.
PROVISIONAL SPECIFICATION left by the said Henry Henson
Henson and William Frederick Henson at the Office of the
Commissioners of Patents, with their Petition, on the 17th
January 1853.
We, HENRY HENSON HENSON and WILLIAM FREDERICK HENSON,
both of Hampstead, in the County of Middlesex, Civil Engineers, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
SIGNALIZING ON RAILWAYS, AND IN THE APPARATUS USED THEREIN," to be as
follows:-
Our Invention consists in enabling the guard of a train to signalize
the engine driver by means of a chain running the whole length of the
train from the guard's box, and attached to a lever (or other suitable

page_text: mechanical arrangement) which on being actuated opens the whistle of
the engine, and thus sounds an alarm, and attracts the driver's attention.
The guard is to be provided with a semaphore similar to those now
usually fixed at intervals on railways, and having attracted the driver's
attention makes such signal by means of the semaphore as he wishes to
convey. Flags may be used either in combination with the semaphore
or separately as day signals, but at night signal lamps must be used in
lieu of flags. The guard may open the steam whistle by pulling a
chain, wire, or rope connected to the lever, which causes the whistle to
sound, and such chain, wire, or rope may be carried in lengths in a
tube on each side of every carriage in a train, the lengths of chain or
rope being united at the time of the carriages being coupled. The
driver may in like manner communicate with the guard by means of a
bell, and in the case of a long train one guard could communicate with
another guard in a different carriage.
In lieu of sounding the whistle, the guard's rope might be made to
sound a bell or series of bells, but we should prefer the whistle on
account of the greater aların it would give. It might also be attached
to some part of the driver's person.
My improvements in the apparatus used in signalizing consist in
new arrangements of reflectors and bull's eyes for the lamps so as to
shew a more brilliant and extended light.
