PROVISIONAL SPECIFICATION.
Improvements in Wheels for Carriages and other Vehicles.
I, JOHN WARDEN BAIRD 7 Union Street, Edinburgh, Engineer, do hereby declare
the nature of this invention to be as follows:-
This invention which relates to wheels for carriages and other vehicles has for its
object to obviate in great measure vibration occasioned in travelling over rough
ground.
To that end I fit elastic pads or cushions of rubber or metallic or other springs
between the spokes and the rim or tyre of the wheel and which whilst serving as
buffers and distributing or absorbing the vibration or jerky movements of the wheel
are not so subject to wear as are the rubber or other elastic tyres used for the like
purpose. These cushions or buffers are placed each within a box or casing of
cylindrical or other form fitted on the ends of the spokes which may be either
wooden or in the form of rods connecting the nave to lugs formed on each side
of the casing; and on the inner periphery of the wheel rim or tyre are fitted or
formed pins or studs on which are cast or fixed plates or heads to bear on the
buffers within the casings terminating the spokes the inner ends of the buffers
bearing on a fixed or movable bottom plate in the casing or on the ends of the
spokes when these are of wood and fitted into the casing.
Dated this Twenty-fifth day of November 1889.

COMPLETE SPECIFICATION.
Improvements in Wheels for Carriages and other Vehicles.
I, JOHN WARDEN BAIRD, 7 Union Street, Edinburgh, 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 which relates to wheels for carriages and other vehicles has for its
object to obviate in great measure vibration occasioned in travelling over rough
ground.
To that end I fit elastic pads or cushions of rubber or metallic or other springs
between the spokes and the rim or tyre of the wheel and which pads whilst serving as
buffers and distributing or absorbing the vibration or jerky movements of the wheel
are not so subject to wear as are the rubber or other elastic tyres used for the like
purpose.
As represented in the accompanying drawings which show a modification of my
invention in elevation at Figure 1, in cross section at Figure 2, and in detail at
Figures 3, 4 and 5, the cushions or buffers A, are placed each within a box or
casing B, of cylindrical or other form fitted on the ends of the spokes which may be
either wooden or in the form of rods C, connecting the nave D, to lugs formed on
each side of the casing; and on the inner periphery of the wheel rim or tyre E,
are fitted or formed pins or studs F, on which are cast or fixed plates or heads f,
to bear on the buffers A, within the casings B, terminating the spokes the inner
ends of the buffers bearing on a fixed or movable bottom plate or block in the
casing or in the ends of the spokes when these are of wood and fitted into the casing
or as shewn the inside bearing plate may be in the form of an inner tyre G.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A wheel for carriages or other vehicles constructed substantially as hereinbefore
described with reference to the accompanying drawings.
2. A wheel for carriages or other vehicles having rubber or spring buffers fitted
between the spokes and rim or tyre substantially as described and for the purpose set
forth.
3. In a wheel for carriages or other vehicles the box or casing B, attached to the
spokes and adapted to carry an elastic pad or cushion interposed between said spokes
and the tyre substantially as and for the purpose set forth.
Dated this Twenty-fifth day of August 1890.
