Complete Specification Left, 19th Sept., 1899-Accepted, 21st Oct., 1899
Improved Signalling Apparatus for the Protection of Platelayers
on Railways.
I, CHARLES CROPP, 22, Pownell Road, Fulham, Gardener, do hereby declare
the nature of this invention to be as follows:-
This invention relates to improved signalling, apparatus for the protection of
plate layers on railways.
In carrying out my invention I provide a block which carries a movable contact
piece so arranged that the wheel of the engine when passing over a projecting
spring piece, will close an electrical circuit. Wires are carried a suitable distance
up the line from this contact piece and may be in communication with an electric
bell or other suitable form of alarm. The block carrying the contact pieces for
closing the circuit may be attached in position by any suitable arrangement.
By this arrangement it will be seen that when the engine passes over the block
the circuit being closed the signal may be given the required distance in front of
the engine, thus notifying the platelayers or other individuals of its approach.

Improved Signalling Apparatus for the Protection of Platelayers
on Railways.
I, CHARLES CROPP, 22, Pownell Road, Fulham, Gardener, 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 improved signalling, apparatus for the protection of
platelayers on railways.
In carrying out my invention, I provide a block which carries a movable con-
tact piece so arranged, that the wheel of the engine when passing over a pro-
jecting spring piece will close an electrical circuit. Wires are carried a suitable
distance up the line from this contact piece and may be in communication with
an electric bell or other suitable form of alarm. The block carrying the contact
pieces for closing the circuit may be attached in position by any suitable arrange-
ment. By this arrangement, it will be seen that when the engine passes over the
block the circuit being closed the signal may be given the required distance in

page_text: front of the engine thus notifying the platelayers or other individuals of its
approach.
For purposes of illustration, I will now refer to the annexed drawings in
which:
Figure 1, is a sectional side elevation shewing my invention applied to a rail.
The block a, carries the spring piece b which is so arranged, that upon the
passage of the flange of a wheel over same, this piece is depressed, and causes
the contact pieces c & d to touch each other, and so close an electric circuit. This
electric circuit is for the purpose of enabling a bell to be rung, a sufficient distance
from the signalling apparatus in order to give the platelayers or workmen warn-
ing of an approaching train. The block carrying the contact piece may be
attached to the rail or sleeper in any convenient manner such as by bolting. By
this arrangement, according to the length of wires, say for instance 50 yards, the
workmen or plate layers will receive a signal at a distance of 50 yards for the
purpose of preventing accident. The device may be moved from place to place as
required according to the work in hand.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
1. In signalling apparatus of the class herein described, the combined con-
struction, and arrangement of the various parts, substantially as described &
illustrated herein, and for the purpose set forth.
2. The improved signalling apparatus, consisting of a block carrying, a spring
piece, contact pieces which are operated by said spring upon the passage of the
wheel over same, said contact piece closing a circuit, which may ring a bell or
give other alarm, through the medium of wires or leads at a suitable distance
said block being attached to the rail or sleeper in any convenient manner, sub-
stantially as described, and illustrated herein, and for the purpose set forth.
Dated this 19th day of September 1899.
