RESERV
I, ANDREW JOHNSTON of Ipswich, Suffolk, District Engineer, Great Eastern
Railway, do hereby declare the nature of this invention to be as follows:-
The object of this invention, is to utilize a portion of a Railway platform as a crossing
gate by mounting it on a pivot to be swung across the metals, it then serving as a
bridge for pedestrians. I purpose having it in connection with the signals so that no
motion can be given to it, for crossing purposes, while the danger signal is set for
the passage of a train but which platform and gate when the line is clear can be swung
over and so form a temporary bridge for pedestrians. The space between that and
the fixed platform being availablo for the passage of carts and other vehicles.
If portions of two platforms on the two sides of the line are thus constructed they
may meet or be otherwise arranged to complete a passage across the metals.
This invention is applicable for Railway Stations having short platforms as an
extension and thereby allow a greater number of carriages to be drawn up especially
in those cases where a level crossing is situate at the end of a platform which
necessarily limits its length.
My swing platform may be composed of wood or metal arranged girder fashion
with a wire or lattice back and is pivotted at one end on a post and has a balance
weight either above or below the surface of the ground so that very littte labour will
be necessary to swing it which swinging may be mechanically effected if desired.
Plates concentric to the pivot may be fitted on the ground for wheels of the platform
gate to run on.

ANDREW JOHNSTON, M. Instn. C.E. District Engineer Great Eastern Railway,
Ipswich, Civil Engineer do hereby declare the nature of my invention for COMBINED
LEVEL CROSSING GATE AND PLATFORM FOR RAILWAYS and in what manner the same
is to be performed, to be particularly described and ascertained in and by the following
statement :-
My invention has for its object a method by which Railway platforms A. A can be
extended over level crossings B B without constructing a bridge; the platform CC
acting as a gate on a level crossing so that when the structure is parallel to the
Railway it acts in the double capacity of a gate across the roadway and as a platform
for passengers to alight.
When swung across the rails it acts as an ordinary crossing gate shut across the
line to allow of pedestrian and vehicular traffic to pass over the Railway. The platform
is to work on a pivot, D or rollers, or a pivot and rollers, fixed at or near one end of
the combined crossing gate and platform. It is intended to be interlocked with the
signals so that no motion can be given to it when a train has been signalled. This 1
invention is applicable for Railway Stations having platforms abutting on a level
crossing which otherwise could not be extended E E without erecting a bridge.
My swing platform-may be composed of wood or metal and is arranged as a
swinging cantilever balanced on a pivot and counterbalanced if necessary; so that
little labour is required to actuate the combined platform & crossing gate.
It has a fence constructed at the back to form the gate it is also fitted with
adjustable wheels which serve as supports to the above described structure.
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.
1st. That my invention combines a platform with a level crossing gate for
Railways.
2nd. It allows platforms to be extended over level crossings.
3rd. It enables a platform to be lengthened without constructing a bridge over or
under the Railway.
