do hereby declare the nature of this invention to be as follows:-
The contrivance consists of a double set of wheels all keyed on to the same axle the
two inner wheels being slightly smaller in diameter than the two outer wheels the
difference only being sufficient to enable the pair of wheels not in use to keep clear of
the roadway when crossing points; at all points, switches, level crossings &c. the
metals to be laid broad gauge.
The pair of wheels not in use help the engine over the dead centres.
At all changes of gauge the metals on to which the train is to run should be
laid at a slightly rising incline so that the train may run on to them without the
slightest jolt.
Fig. 1. shows a front view of a pair of wheels running on the broad guage with the
inner wheels for narrow guage disengaged.
Fig 2. shows the method of changing from the broad guage X X to the narrow
gauge Y Y by slightly inclining the metals.. B shews the broad guage wheels in use
