PROVISIONAL SPECIFICATION.
Improvements in the Construction of Wheels and Tyres for Carriages
and other Road Vehicles.
We, WALTER SWAIN of 177 Belmont Road, Land Agent, and WILLIAM
PHILIPSON of Holland Street Iron Works, Engineer, both of Astley Bridge near
Bolton in the County of Lancaster, do hereby declare the nature of our said
invention to be as follows:-
This invention relates to unprovements in the construction of wheels and tyres
for carriages and other road vehicles, and consists in making the rim of the wheel
of wood or other materials on the outer periphery of which is mounted a metallic
or other concaved rim secured by screws or other means. In the concaved rim we
dispose a pneumatic or other tyre inflated by means of air, gas, or liquids under
pressure. This tyre we protect and secure in position by means of canvas or other
material with an outer covering of india-rubber or other like substance. The canvas
or other material extends over the inflated tyre and down the sides of the rim of
the wheel, being secured to the latter by metallic rings or plates fastened by means
of bolts or screws. The rim of the wheel may be grooved to allow of the securing
rings or plates being flush with the sides of the rim. If desired we can dispense
with the securing rings or plates in which case the canvas is passed down and
secured to the inner periphery of the wheel rim in any convenient manner.
further protect the pneumatic or other inflated tyre from damage and being cut
when travelling over rough roads we encircle the outer rim of canvas and india-
rubber or other like substance with a sole or other rim of equal or unequal
thickness according to the amount of bearing it is intended to present to the road.
This outer sole or rim is secured by india-rubber or other solution, which will allow
of the same being removed when worn and replaced by another without interfering
with the other parts of the wheel or tyre.

COMPLETE SPECIFICATION.
Improvements in the Construction of Wheels and Tyres for Carriages
and other Road Vehicles.
We, WALTER SWAIN of 177 Belmont Road, Land Agent, and WILLIAM
PHILIPSON of Holland Street Iron Works, Engineer, both of Astley Bridge near
Bolton in the County of Lancaster, do hereby declare the nature of our said inven-
tion 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 in the construction of wheels and tyres
for carriages and other road vehicles, and consists in making the rim of the wheel
of wood or other materials on the outer periphery of which is mounted a metallic
or other concaved rim secured by screws or other means. In the concaved rim we
dispose a pneumatic or other tyre inflated by means of air, gas, or liquids under
pressure. This tyre we protect and secure in position by means of canvas or other
material with an outer covering of india-rubber or other like substance. The
canvas or other material extends over the inflated tyre and down the sides of the
rim of the wheel, being secured to the latter by metallic rings or plates fastened by
means of bolts or screws. The rim of the wheel may be grooved to allow of the
securing rings or plates being flush with the sides of the rim. If desired we can

page_text: dispense with the securing rings or plates in which case the canvas is passed down
and secured to the inner periphery of the wheel rim in any convenient manner..
To further protect the pneumatic or other inflated tyre from damage and being
cut when travelling over rough roads we encircle the outer rim of canvas and india-
rubber or other like substance with a sole or other rim of equal or unequal
thickness according to the amount of bearing it is intended to present to the road.
This outer sole or rim is secured by india-rubber or other solution, which will
allow of the same being removed when worn and replaced by another without
interfering with the other parts of the wheel or tyre.
Fig. 1 is a part side and sectional elevation of our improved construction of
wheels and tyres for carriages and other road vehicles, such as, bicycles, tricycles,
and the like. Fig. 2 is a transverse section through line A B in Fig. 1, and
Fig. 3 is a transverse section of another modification of the same invention.
On the rim C of the wheel, which may be of wood or other materials, we mount
the metallic or other concaved rim G, and secure the same thereon by means of
the screws E or their equivalents. In the concaved rim G we dispose the pneumatic
or other tyre consisting of the india-rubber or other tube I covered with the
canvas or canvas bag K. The india-rubber or other tube I is inflated by means
of air, gas, or liquids under pressure, and is protected from damage and being cut
when travelling over rough or other roads by means of the sole O of india-rubber
or other like substance or material. The sole O is of unequal thickness and of
the form or section shown in Fig. 2, and is provided with a flat, or almost flat,
bearing surface of the width it is intended to present to the road; the whole being
mounted on the canvas P which extends down the sides of the rim C of the wheel
into the grooves, wherein it is secured by the metallic rings or plates D fastened
in position by the screws F, or by other equivalents such as bolts. The grooves in
the sides of the wheel rim C are of sufficient depth to allow of the outside of the
metallic rings or plates D being flush with the same as shown in Fig. 2. An
important feature of this invention is the ready means it presents of examining
and for placing and removing the inflatable tube I on and from the concaved
rim G on the rim C of the wheel, which is effected by removing the metallic
rings or plates D, when the sole O can be removed bodily.
In the modification shown in Fig. 3 the ends of the canvas P pass down to
the inner periphery of the rim C of the wheel, at which point one end overlaps
the other, being secured by cement, or other means, thereby dispensing with the
metallic rings or plates D shown in Figs. 1 and 2. To further protect the
pneumatic or other inflatable tube I, the flat outer surface of the sole O is
provided with the india-rubber or other sole or rim O' of equal thickness, being
secured thereon by india-rubber or other solution or cement, which will allow of
the same being removed when worn and replaced by another without interfering
with the other parts of the wheel or tyre. The wood or other spokes V are
secured to the rim C of the wheel in the usual manner.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what we
claim is :-
1. The form or section of the india-rubber or other elastic sole O with a flat
rolling surface of unequal thickness for protecting pneumatic tyres of wheels for
carriages, bicycles, tricycles, and other road vehicles.
2. In combination with a pneumatic tyre consisting of an india-rubber or other
elastic pressure tube and a canvas or other covering, the use of an india-rubber
or other elastic sole with a flat rolling surface of unequal thickness mounted on
canvas, and secured to the rim of the wheel for the purpose specified, substantially
as described.
3. In a pneumatic tyre consisting of an india-rubber or other elastic pressure
tube and a canvas or other covering, the combination of a metallic concaved rim
secured to the outer periphery of the wheel rim, an india-rubber or other elastic

page_text: sole with a flat rolling surface of unequal thickness mounted on canvas, the whole
being secured to the rim of the wheel, substantially as described and as shown
in the drawings.
4. In a pneumatic tyre composed of an india-rubber or other elastic pressure
tube, a canvas or other covering, and an india-rubber or other elastic sole with
a flat rolling surface of unequal thickness, the combination of an outer rim or
ring of india-rubber or other elastic material of equal thickness secured thereon.
by india-rubber or other solution or cement, for the purpose specified, substantially
as described.
