COMPLETE SPECIFICATION.
Improvements in Railway Signalling.
We Joux MoNKS of 20 Lucas Road, Chorley, Lancashire and ROBERT
NEWLAND BUSH of 146 Pall Mall, Chorley, Lancashire, Machine Printer and
Brewer respectively, 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 :-
Our invention relates to improved means for imparting a signal to a moving
train which signal may be either applied to the engine or to the guard's brake,
as desired.
To clearly explain the nature of our invention we have illustrated it in the
accompanying drawing in which the moveable signal shown as applied to the cab
of an engine with the means for operating same. In the drawing,
Fig. 1. shows a portion of an engine cab with the signal "off" or at rest.
Fig. 2 shows the signal as operated to call the attention of the driver.
Fig. 3 is a view on an enlarged scale of the rod or frame which is placed at the
side of the rail and is operated from the signal box to move the signal on the
cab and
Fig. 4 is a view of an enlarged scale of the signal and operating parts.
The signal consists of a moveable arm a suitably pivoted and counterbalanced
which is operated by a vertical rod & preferably attached to it by a pin working in
a slot as shown. The signal may be situated in any part of the cab, though we
find it convenient to place it in front of the lookout windows where it is likely to
quickly attract the attention of the driver. The rod passes down by the side of
the engine frame and terminates in a roller c which is adapted to be struck by the
rod or frame d which is pivoted at the side of one of the rails. the ends of said rod
or frame being sloped away to allow the roller to gradually travel up and down it.
This frame d may be operated by an arm e to which are connected suitable rols or
the like to enable it to be turned up or down by the signalman from his box, said
rods being connected to or forming part of the rods operating the ordinary signal
arm so that when the latter is put at "danger" the frame d will be raised up and
will through the rod operate the signal arm a so that it gives a similar indication
upon the moving train. The signal arm or a part thereof in its movement may
also be caused to strike a gong so as to draw the driver's or guard's attention to
It will be evident that the frame d may be of such length as will hold the
same.

signal on the cab at
danger for such a period as will enable the train to be
stopped prior to reaching or passing the fixed line signal so that both signals may be
together lowered when the line is clear.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
signal on the cab at "danger" for such a period as will enable the train to be
stopped prior to reaching or passing the fixed line signal so that both signals may be
together lowered when the line is clear.
Having now particularly described and ascertained the nature of our said inven-

claim is :-
The improved means for signalling on a train substantially as described and
illustrated.
