Improvements in Vehicles for Railways.
I, ARTHUR JAMES HAMILTON-SMYTHE of 9 Victoria Street Westminster
London S.W. Civil Engineer do hereby declare the nature of this invention to
be as follows:-
:
An arrangement for reducing resistance from friction to one or more of some
vehicles passing round some curve or curves on some railway or railways by
affixing to said vehicle or vehicles horizontal rollers to revolve on vertical axes
between, or adjacent to one or more of the wheels of said vehicle or vehicles
in such a manner that when said vehicle or vehicles is or are passing round said.
curve or curves one or more of said horizontal rollers may press and revolve
against one or more of the rails of the said railway or railways.

Improvements in Vehicles for Railways.
I ARTHUR JAMES HAMILTON-SMYTHE, of 9, Victoria Street, Westminster,
London, S. W., Civil 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:-
Figure 1 on the annexed sheet of drawings is a plan of part of a vehicle with my
invention applied thereto.
Figure 2 is a cross-section through one of the bearing axles of the vehicle shown
on the plan and Figure 3 is a longitudinal section through the centres of both the
bearing axles shown on the plan.
The same letters of reference indicate corresponding parts in all the figures.
A. A. are rails of a railway, B. B. are flat-tyred bearing wheels of a vehicle
thereon, C. C. are bearing axles of the vehicle, D. is a metal casting, E. E. are
vertical metal axes having loose tyres F. F. which are free to travel round the
axes E. E. against interposed trains of metal rollers G. G., which vertical metal
axes E. E. are hung from D. by screw bolts H. H. passing through E. E. and
kept in tension by metal axle-bearings I. 1. Q. Q. are strutting bars or connecting
rods. The metal casting D. with the axes E. E. can be raised or lowered within
certain limits by turning the screw-head J. which works the screw K. through the
metal casting D., the screw K. having part of the under-framing L. of the carriage
or body of the vehicle to serve as a fulcrum. M. is a spring or pile of washers
composed of metal, or of rubber, or of both, placed between J. & L. The screw-
head J. is prolonged to pass through M. & L. and is secured at the top by a
locked or keyed nut N. The loose tyres F. F. are kept in position by annular
metal washers O. U., which are themselves kept in position by screw-bolts P. P.
passing through them and through the metal rollers G. G. for which the screw-
bolts P. P. serve as axes.

page_text: 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
Attaching to, or adjacent to, axles of pairs of flat-tyred bearing-wheels of
vehicles, vertical metal 'axes having loose tyres travelling round them against
interposed trains of metal rollers and adjustable in positions to bear against
inner sides of railway rails when required as substitutes for the ordinary flanges
of railway wheels, substantially as hereinbefore described.
Dated this Fifteenth day of January 1895.
