PROVISIONAL SPECIFICATION.
Improvements in Fog Signalling Apparatus for Railways.
We, WELLINGTON SMITH of 9 James Street, Engine Driver and GEORGE STEPHENSON
of 9 Whiteley Street, Fireman, both of Tong Road, New Wortley in the County of
York, do hereby declare the nature of this invention to be as follows:-
The object of our invention is to construct apparatus which can be readily applied
at any moment when fogs come on suddenly or otherwise, whereby signals are given
at the distant and near signalling points to the driver of the engine.
For the above purpose we employ switches at the near and distant signalling points,
these switches may be worked from. the signal boxes or from any other convenient
position. On each switch are mounted in suitable bearings any required number of
rollers or discs, as for instance, there may be three at the distant signalling point
and two at the near signalling point, and on the engine passing along the line and
the switches being thrown into the proper position for signalling a lever or levers
in connection with a bell arrangement on the engine or tender comes in contact with
the runners or discs causing the bell or gong to ring as many times as there are
discs, these signals being known by the driver give him quite sufficient warning to
regulate or stop the speed of the engine as required, when preferred the rollers or
discs may be placed in fixed bearings and the lever or levers on the engine or
tender are then made capable of being thrown out of action.

Improvements in Fog Signalling Apparatus for Railways.
We WELLINGTON SMITH of 9 James Street, Engine Driver and GEORGE STEPHENSON
of 9 Whiteley Street, Fireman, both of Tong Road, New Wortley in the County of
York, 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 object of our invention is to construct apparatus which can be readily applied
at any moment when fogs come on suddenly or otherwise, whereby signals are
given at the distant and near signalling points to the driver of the engine.
In the accompanying drawings Fig. 1 is a side elevation and Fig. 2 a plan shewing
our improvements.
For the above purpose we employ switches A at the near and distant signalling
point, these switches may be worked from the signal boxes or from any other
convenient position. On each switch A is mounted in suitable bearings B a roller
or disc C; and we may employ any required number of such rollers or discs; as
for instance, there may be three at the distant signalling point (as shown in the
drawings) and two at the near signalling point, and on the engine D passing along
the line E and the switches being thrown into their proper position for signalling
as shewn in the drawings a lever For levers in connection with a bell arrangement
on the engine or tender, comes in contact with the runners or discs C, causing the
bell G or gong to sound as many times as there are rollers or discs. These signals
being known by the driver give him quite sufficient warning to regulate the speed
of or to stop the engine as required.

page_text: When preferred the rollers or discs may be placed in fixed bearings, and the lever
or levers on the engine or tender made capable of being thrown in or out of action
therewith.
Having now particularly described and ascertained the nature of our said inven-
tion, we declare that what we claim is :-
The arrangement, construction and combination of the various parts forming the
fog signalling apparatus, substantially as herein set forth.
