I ROBERT WILSON of 7 Westminster Chambers Victoria Street Westminster in the
County of Middlesex Engineer, do hereby declare the nature of this invention to be
as follows:-
This invention relates to an improvement upon the invention for which I (in con-
junction with Joseph Cunliffe) obtained Letters Patent bearing date 15th September 1884
No. 12392, the object of the present invention being to afford greater facilities for
inspecting and oiling the axle boxes than existed in trucks made according to the
Specification of such Letters Patent.
I make the trucks with a bogio frame as before and I use the flanged wheels fixed
on the axle, together with an additional removable set of wheels of rather larger
diameter than the flanged wheels and having rims adapted for running upon ordinary
roads, and a removable pole or shaft; but instead of placing the axle boxes inside of
the flanged wheels as described in the Specification of the previous Patent above
mentioned (which has been found to be inconvenient on account of the difficulty of
inspecting and oiling the same when in that position) according to my present
invention I propose to place the said axle boxes outside the said wheels so as to be
easy of access for inspection and oiling and in order to allow of the use of the
removable external road wheels when required I dispense with the ordinary axle, and
I substitute therefor an axle of increased length having outside the axle boxes at
each side of the truck an elongation to receive the boss or hub of one of these wheels
so that they may revolve loosely thereon when required for use on ordinary roads,
the flanged wheels being both keyed fast upon the axle as usual.
:
By these means I obtain all the advantages possessed by the former invention above
referred to and at the same time the axle boxes are as accessible for inspection and
oiling as those of the trucks in ordinary and common use.

page_text: I ROBERT WILSON of 7 Westminster Chambers Victoria Street Westminster in the
County of Middlesex 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 :—
This invention relates to an improvement upon the invention for which I (in con-
junction with Joseph Cunliffe) obtained Letters Patent bearing date 15th September 1884
No. 12392, the object of the present invention being to afford greater facilities for
inspecting and oiling the axle boxes than existed in trucks made according to the
Specification of such Letters Patent.
The nature of my said invention and the manner in which the same is to be carried
into practical effect will be readily understood on reference to the annexed sheet of
drawings and the following explanation thereof.
Fig. 1. is a half transverse section and end view of a railway truck made and
fitted according to my invention and Fig. 2 is a view of the improved axle detached.
I make the trucks with a bogie-frame a, a as before and I use the flanged wheels b, b
fixed on the axle c, e together with an additional removable set of wheels of rather
larger diameter than the flanged wheels as shown by the dotted lines in Fig. 1 and
having rims adapted for running upon ordinary roads and a removable pole or shaft:
but instead of placing the axle boxes d, d inside of the flanged wheels b, as described
in the Specification of the previous Patent above mentioned (which has been found to be
inconvenient on account of the difficulty of inspecting and oiling the same when in that
position), according to my present invention I propose to place the said axle boxes outside
the said wheels so as to be easy of access for inspection and oiling as shown at the
left hand of Fig. 1 and in order to allow of the use of the removable external road
wheels when required I dispense with the ordinary axle, and I substitute therefor an
axle c, c (Fig. 2) of increased length having outside the axle boxes at each side of the
truck an elongation c¹ to receive the boss or hub of one of these external road wheels
so that they may revolve loosely thereon when required for use on ordinary roads,
the flanged wheels being both keyed fast upon the part e*, of the axle as usual.
By these means I obtain all the advantages possessed by the former invention
above referred to and at the same time the axle boxes are as accessible for inspection
and oiling as those of the trucks in ordinary and common use.

page_text: Having now particularly described and ascertained the nature of my said Inventio
and in what manner the same is to be performed I declare that what I claim is:
--
The improvements in railway trucks consisting of an axle of increased length
having at oach end outside the axle box an elongation fitted to receive the boss or
hub of a removable rond wheel (of a larger diameter than the flanged wheel of the
truck) the flanged wheels being keyed fast on the axle as usual and the road wheels
fitted loosely on the same axle so as to revolve freely; whereby the truck is able to
be run upon a railway or a common road when required, at the same time that the
axle boxes are as accessible for inspection and oiling as those of the ordinary trucks.
