Improvements relating to Railway and other Vehicles.
1, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings in the County of Middlesex, do hereby declare the naturo of
this invention to be as follows:-
This invention relates to improvements chiefly applicable to railway rolling stock of
any kind, of any dimensions and for any purposes.
According to the said invention the axles are provided with ordinary wheels but
the connection between the truck and the body of a vehicle will be established as
follows.
Each axle at the points where the load is carried is provided with a metallic
cylindrical sleeve. The diameter of this cylinder is about two centimetres greater
than that of the axle.
Each sleeve is bored out excentrically so that the centre of its exterior will be
situated at about a centimetre from the axis of rotation of the axle.
The excentric thus arranged turns in a cylindrical support that carries the supporting
rods of the frame or body of the vehicle, the said supporting rods being connected
with the frame or body either directly or by springs exactly as in vehicles as heretofore
constructed.
It will therefore be understood that the rotation of the excentrics imparts to the
supports, to the supporting rods, to the frame or body of the vehicle and to its contents
a particular motion such that each point describes a circle whose radius is equal to the
excentricity or to the distance between the centre of the axle and the centre of the
excentrics in a plane parallel to that of the truck wheels.
If when traction is applied to the vehicle the motion is normal, the axle turns in a
hollow cylinder which receives a circular movement. Thus a cylinder turning upon
a cylinder to which the same motion is imparted.

page_text: Provided that the traction keeps up the rotation of the wheels upon the rail, there
will not be any notable resistance to the continuation of this circular motion, and
consequently to the forward motion.
On starting and during the increasing velocity the friction is proportional to the
increase of velocity between the axle of the wheels tonding to move quicker and the
frame or body then moving less rapidly. But the weight, which acts as a resistance
during the ascending semi-circular oscillation of the load, acts as an aid during the
descending oscillation.
To the horizontal velocity thus obtained I add a circular velocity.
To the advantages in point of velocity economy can be added it being possible to
diminish the diameter of the wheels without greater resistance if either the weight of
the rolling stock were to be diminished, or the level of the load lowered.

I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex 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 improvements chiefly applicable to railway rolling stock of
any kind of any dimensions and for any purpose.
According to the said invention the axles are provided with ordinary wheels but
the connection between the truck and the body of a vehicle will be established as
follows:
Each axle at the points where the load is carried is provided with a metallic
cylindrical sleeve fixed thereto. The diameter of this cylinder is about two centi-
metres greater than that of the axle.
Each sleeve is bored out eccentrically so that the centre of its exterior will be
situated at about a centimetre from the axis of rotation of the axle.
In the accompanying drawing
A is the centre of the axle and E the centre of the sleeve.
The eccentric thus arranged turns in a cylindrical support that carries the supporting
rods of the frame or body of the vehicle the said supporting rods being connected
with the frame or body either directly or by springs exactly as in vehicles as heretofore
constructed.
It will then be understood that the rotation of the eccentrics imparts to the
supports, to the supporting rods, to the frame or body of the vehicle, and to its
contents, a particular motion such that each point describes a circle whose radius is
equal to the eccentricity or to the distance between the centre A of the axle and the
centre E of the eccentrics in a plane parallel to that of the truck wheels.
If when traction is applied to the vehicle the motion is normal, the axle turns in a
hollow cylinder which receives a circular movement. This is a cylinder turning upon
a cylinder to which the same motion is imparted.
Provided that the traction keeps up the rotation of the wheels upon the rail, there
will not be any notable resistance to the continuation of this circular motion, and
consequently to the forward motion, and the traction of the truck to which in this
state circular motion is imparted will be sensibly equal to that of the empty truck.
On starting and during the increasing velocity the friction is proportional to the
increase of velocity between the axle of the wheels tending to move quicker and the
frame or body then moving less rapidly. But the weight, which acts as a resistance
during the ascending semi-circular oscillation of the load, acts as an aid during the
descending oscillation. Accordingly there is no difference between the traction
required for the empty and full truck.
To the horizontal velocity thus obtained I add a circular velocity.

page_text: To the advantages in point of velocity, economy is added, the possibility of
diminishing the diameter of the wheels without greater resistance if either the weight
of the rolling stock were to be diminished, or the level of the load lowered.
It is obvious that various modifications in the construction may be performed without
departing from the nature of the invention.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed as communicated to me by my foreign
correspondent I declare that what I claim is :-
First. In a vehicle, the arrangement, in the part which carries the load of the axle
provided with a metallic sleeve adhering thereto as above described.
Second. The arrangement of the eccentric sleeve turning in a cylindrical slide that
carries the supporting rods of the frame or body of the vehicle as above specified.
