We FREDERICK DALE BANISTER of Stonehouse, Forest Row, in the County of
Sussex, Civil Engineer, and WILLIAM STROUDLEY of Bosvigo, Preston Park, Brighton
in the County of Sussex Locomotive and Carriage Superintendent to the London
Brighton and South Coast Railway Company, London Bridge do hereby declare
the nature of this invention to be as follows:-
This invention relates to improvements on the invention for which Letters Patent
were granted to us bearing date the 15th day of December 1874 No. 4311.
<:
According to the specification of the said invention the mechanism for bringing
the thin steel sliding plates or jolting pieces" over the rail and withdrawing them
therefrom was so combined with the mechanism which worked the Visual signals that
the one could not be worked without the other and hence in the event of the engine
or other wheels of the train coming to a standstill upon the jolting piece or pieces
the visual signals could not be worked until the wheels had passed from off the said
pieces.
Now according to the present invention it is proposed to so combine with the
aforesaid arrangement a weight whereby the jolting piece or pieces can be forced
over the rail or put into positive action even should the signal wire become broken,
the same as in the ordinary signal arrangements, also to so combine with the aforesaid
arrangement à spring or springs whereby the jolting piece or pieces can be withdrawn
from off the rail independently of the signal lever but only permitted to act when the
lever is pulled by the signalman thus admitting the lowering of the visual signal
although the wheels of the engine or other part of the train may be standing upon
the jolting piece or pieces.

Improvements in Fog Signal Apparatus for Railways.
We FREDERICK DALE BANISTER of Stonehouse, Forest Row, in the County of
Sussex, Civil Engineer and WILLIAM STROUDLEY of Bosvigo, Preston Park, Brighton
in the county of Sussex, Locomotive and Carriage Superintendent to the London
Brighton and South Coast Railway Company London Bridge 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 :-
This invention relates to improvements on the invention for which Letters Patent
were granted to us bearing date the 15th day of December 1874 No. 4311.
According to the specification of the said invention the mechanism for bringing
the thin steel sliding plates or jolting pieces over the rail and withdrawing them
therefrom was so combined with the mechanism which worked the Visual signals that
the one could not be worked without the other and hence in the event of the engine
or other wheels of the train coming to a standstill upon the jolting piece or pieces
the Visual signals could not be worked until the wheels had passed from off the said
pieces.
Now the object of our present invention is to enable the jolting piece or pieces to
be automatically forced over the rail or put into positive action, by a weighted lever
for example, even should the signal wire become broken, the same as in the ordinary
signal arrangements and also to enable the jolting piece or pieces to be automatically
withdrawn from off the rail by the action of a spring for example independently of
the signal lever such spring however being only permitted to act when the lever is
pulled by the signalman thus admitting of the lowering of the semaphore signal even
should the jolting piece or pieces be fixed at the time by the standing thereon of the
wheel or wheels of the Engine or other part of the train.
Figure 1 of the Drawings annexed is a side elevation of our improved mechanical
fog signal shown applied to one of the rails of a permanent way.
Figure 2 is a corresponding plan of the same.
Figure 3 is an end view of the apparatus, looking on the inner side of the rail.
Figure 4 is a transverse vertical section of the fixed frame or bed plate taken along
the line 1-2 in figure 2 and showing the weighted and quadrant levers and guide
pulley in elevation.
A is the ordinary double beaded rail and B a metal frame or bracket firmly secured
thereto near the stop signal by wedges a or otherwise as described in our said former
specification. CC are the thin steel or other hard metal jolter plates which are pushed
over the rail as shown in figures 1 and 2 when required for fog signalling. These
two plates are guided by the guides B' B¹ on the fixed bracket or frame B and are

page_text: secured by bolts or otherwise to the cross head of the central sliding plate D which
slides longitudinally over the bracket and is guided at its outer end by the stationary
guide B E is a rocking spindle working in a bearing F on the upper surface of
the frame or bracket B and carrying at one end the weighted lever G and at the
opposite end the quadrant lever H the arm of which is brought in contact by the
action of the weighted lever with a notch or lateral projection & (shown more clearly
in figure 2) on the sliding plate D so as to push the latter inwards and bring the
jolter plates C over the rail. The quadrant lever H is connected to the semaphore.
signal lever by the wire e passing round the guide pulley I so that on setting the
semaphore to "danger" the weighted lever G will be simultaneously allowed to act
through the quadrant lever H upon the sliding plate D thereby bringing the jolters C
over the rail as shown in Figures 1 and 2. Should the connecting wire c be broken'
the jolters will remain in action in the position shown leaving the semaphore freo to
be worked independently by its own lever. K is a helical tension spring attached at
one end to the sliding plate D and at the opposite end to a fixed lug L on the
guide B". The object of this spring is to withdraw the jolter plates from off the rail
50-500n as the weighted lever has been raised and the arm of the quadrant lever
drawn back from the notch in the slide D by the act of lowering the semaphore to
"line clear."
Should the withdrawal of the jolter plates be prevented by one of the wheels of
the engine or train resting thereon the Semaphore can be independently set to "line
clear" and immediately on the release of the jolter plates by the starting of the train
they will be withdrawn by the action of the spring K in readiness to be again pushed
forward, when required, by the weighted lever.
Provision may be made for mounting a guide pulley on the opposite side of the
frame B so that the apparatus can be worked in either direction. This apparatus is
not intended to dispense with the ordinary explosive fog signals but to be used, as an
additional safeguard it being always in operation.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed we declare that what we claim is :-
1. In fog sigual apparatus of the class referred to the use in combination with the
jolter plate or plates of a weighted lever and a spring arranged and caused to operate
substantially in the manner and for the purpose hereinbefore described.
2. Combining a fog signal apparatus of the class referred to with the semaphore or
stop signal in such a manner as to allow of the semaphore being lowered even should
the jolter plates be fixed by the resting thereon of the wheel of the Engine or other
part of the train substantially as herein before described.
