PROVISIONAL SPECIFICATION.
Improvements in Means or Apparatus for Supporting the Bodies of
Railway Vehicles.
I ILLIUS AUGUSTUS TIMMIS of No. 2 Great George Street Westminster
London S.W. Civil Engineer do hereby declare the nature of this invention to
be as follows:
The objects of my invention are to lessen the vibration caused in travelling over
an uneven road and deals with vehicles other than bogie vehicles more especially
with those which are carried on four or six wheels.
With these objects in view I place coiled springs as bearing springs instead of
laminated springs. I put two or three or any convenient number between the axle
box and the underframe or body of the vehicle and I group them in any convenient
way for instance I find it convenient to put three springs arranged in a line (or any
other number and grouped in any way). Two of these springs or one of them
support the body of the vehicle and its normal load and the remaining spring or
springs just then come into work and not only help to support the ultimate load but
take up the shocks caused in running over rough or uneven roads and prevent undue
vibration.
The springs may be supported on the axle box or on a support (of metal of any
kind or any suitable material) fitted on the axle box, rigidly or otherwise.
Or a bearer may be fitted on the axle box-pivotted or otherwise-and at the ends
of the beam a hanging bar may support a plate of any convenient shape and on this
may rest any convenient number of springs (by preference two or more).
The tops of these springs rest against the underframe of the vehicle in any
convenient way (say a plate through which the hanging bar passes). One spring
may be placed inside another if desired.
These springs are so arranged that they consist of two systems as above explained
one set support the dead and live load or practically so and the others come then
into work and take up the shocks on uneven roads and prevent undue vibration
especially the downward movement when going over an uneven fish plate or bad
junction and as a consequence the after recoil or upward movement.
The springs may be arranged so that all of them are the same length or some may
be shorter than the others this depends on the way they are fitted.
In a six wheel vehicle I find it convenient sometimes to put weaker springs over
the middle axle boxes or dispense with the auxiliary or extra springs.

I ILLIUS AUGUSTUS TIMMIS of No. 2 Great George 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 ascer-
tained in and by the following statement :-
The objects of my invention are to lessen the vibration caused in travelling over
an uneven road and deals with vehicles other than bogie vehicles more especially
with those which are carried on four or six wheels.
With these objects in view I place coiled springs as bearing springs instead of

DESCRIPTION OF DRAWINGS.
Fig. 1 shows an end axle &c. of a 4 or 6 wheel vehicle with 3 springs supported
on a casting-they are shown in plan in Fig. 2-A' A' are the springs which
practically support the working load and when this condition exists the third
spring B' comes into play and helps to support any extra load and to take up any
shocks or oscillations in travelling.
Figs. 3 and 4 show the centre axle of a 6 wheel vehicle where the auxiliary
spring B' is dispensed with for well known reasons.
These arrangements may be varied in many ways.
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
An arrangement of coiled springs over the axles of 4 or 6 wheel vehicles whereby
one part of them support the load and then the other part helps to support any
extra load and take up shocks and prevent undue vibration and oscillation when
running substantially as and for the purposes hereinbefore described.
