PROVISIONAL SPECIFICATION.
Improved Means for Signalling on Railways.
ROBERT BEEL of 103 Lancaster Street Newington Causeway in the County
of Surrey, Mechanical Engineer, do hereby declare the nature of this invention to
be as follows:-
:―
The object of this invention is to enable the signalman to signal direct on to the
engine and guards van by an indicator and sound signal.
According to this invention I suspend two pieces of metal from the engine tender
or guards van, such pieces being bolted together to allow a space at the bottom for
a.roller of a large size to revolve and by it coming in contact with a bridge fixed
between the rails it revolves and works one or more bellows and the air therefrom
is forced along suitable tubes so as to blow a horn or whistle and also work an
indicator so as to show the driver or guard that the signal is at danger or otherwise
as the case may be.
The bridge between the rails is worked by the signalman with the signal.

COMPLETE SPECIFICATION.
Improved Means for Signalling on Railways.
I ROBERT BEEL of 103 Lancaster Street Newington Causeway in the County
of Surrey Mechanical Engineer 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 this invention is to enable the signalman to signal direct on to the
engine and guards van by an indicator and sound signal.
According to this invention 1 suspend two pieces of metal from the engine tender
or guards van such pieces being bolted together to allow a space at bottom for a
roller of a large size to revolve and by its coming in contact with a bridge fixed
between the rails it revolves and works one or more bellows the air therefrom is
forced through suitable tubes so as to blow a horn or whistle and also if desired
work an indicator either on the engine or in the guards van or both so as to shew
the driver or guard or both that the signal is at danger or otherwise as the case
may be.
The bridge between the rails is worked by the signalman with the signal.
And in order that my said invention may be better understood I will now
describe the same with reference to the sheet of drawing accompanying this
Specification in which
Fig. 1. shews plan of my improved means adapted to sleepers.

page_text: t. shows lever pivotted at to one end of which is fixed a wire rope f. which
passes under the roller . the other end being attached to an eye d. fixed to the
bridge B. F. shews two blocks or sleepers supporting the roller g. (shewn at
Fig. 2).
At Figs. 4 and 5, H shews a plate for bolting on to the engine or guards van or
both, to this plate is connected or formed therewith a fork piece I. in which a
roller J. revolves this roller actuates the cranks which in turn actuate the
bellows m by means of the connecting rod 1.
The action is as follows:-When the signal is at danger the signalman actuates
the signal in the usual way and in doing so causes the bridge B. to rise by means
of the springs n. and assume the position shewn at Fig. 2, so that as the train passes
over it the roller J. rolls thereon (this latter being fixed at such a height as to
come in contact with the bridge when it is up in position) and in doing so actuates
the bellows m so as to force air through the pipe . in connection with a whistle or
horn in order to blow same and indicate when the signal is at danger, the signalman
in pulling his lever to signal when the line is clear at the same time pulls the
wire s. which is in connection with the signal thus drawing the bridge down clear
of the roller J. when the train passes over.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :―
I. The improved means for signalling on railways consisting of the bridge B.
operated substantially as and for the purposes set forth.
II. The apparatus shewn at Figs. 4 and 5 of the drawings connected to the
guards van and engine or one of them operated by means of the bridge B. substan-
tially as set forth.
III. The improved means for signalling on railways substantially as set forth.
Dated this 31st day of October 1891.
