Improvements in Elastic Tyres and Rims for the Wheels of Bicycles,
Tricycles, and other Velocipedes or Carriages.
We ROWLEY BENBOW TURNER, of 81 Rue du Midi, Brussels, Merchant and
WILLIAM BOWN, of 308, Summer Lane, Birmingham in the County of Warwick
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention has special reference to that class of rubber tyre for velocipedes
which has a hollow centre, commonly called "cushion tyre," and our improvements
consist in moulding them so as to give the outer surface the appearance of two or
more distinct tyres having hollow centres but in reality only one tyre. The rim,
which is hollow, is formed on the inner side or part where the rubber tyre is fixed
with a corresponding number of concave surfaces so as to fit the convex surfaces of
the rubber tyre; the other side or edge of the rim may be formed of any convenient
shape.
Dated this 29th day of September 1890.

COMPLETE SPECIFICATION.
Improvements in Elastic Tyres and Rims for the Wheels of Bicycles,
Tricycles, and other Velocipedes or Carriages.
We, ROWLEY BENBOW TURNER, of 81 Rue du Midi, Brussels, Manufacturer,
and WILLIAM Bown, of 308 Summer Lane, Birmingham in the County of
Warwick, Manufacturer, 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 :-
This invention has special reference to that class of rubber tyre for velocipedes
which has a hollow centre, commonly called "cushion tyre," but is equally
applicable to pneumatic or solid tyres, and our improvements consist in moulding or
forming the tyre so as to give the outer surface the appearance of two or more
distinct tyres but in reality only one tyre, and also in forming the rim to suit the
rubber tyre.
In order that our invention may be better understood we have annexed the
accompanying sheet of drawings.
Fig. 1 is a view in cross section of a pneumatic tyre and hollow rim constructed
in accordance with our invention.
Fig. 2 is a similar view to Fig. 1 shewing our invention as applied to a cushion
tyre.
Fig. 3 is a view in cross section of a cushion tyre and solid rim shewing the tyre
with the appearance on the outer surface of three tyres constructed in accordance
with our invention.
In Fig. 1: A A are the air tubes, B B the required number of layers of canvas
which are wrapped round the air tubes A A. One side of the said canvas B B is
secured to the rim C by cement or other means, the said rim C being formed
concave so as to fit the convex surfaces of the tyre. The other side of the said
canvas B B is covered with a suitable thickness of india rubber so as to minimise
the liability of the air tubes being punctured when riding the machine.

page_text: In Fig. 2 D D is the rubber tyre which is formed or moulded with two hollow
centres dd, the said tyre D D is secured to the rim C (which is similar to that
shewn at Fig. 1) by cement or other suitable means.
In Fig. 3 E E E is the rubber tyre which is formed or moulded so as to give the
appearance on the outer surface of three tyres with a hole formed in each. The
rim F which is solid is formed concave at its edges so as to fit the convex surfaces
of the edges of the tyre E E E.
Although we have described and shewn our improvements as applied to
velocipede wheels only we can with equal advantage apply them to the wheels of
other carriages or vehicles by forming a special rim for that purpose; and we may
if desired use solid tyres instead of pneumatic or cushion tyres.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we would have it understood
that we do not confine ourselves to the precise details as herein shewn and described
but what we claim is :-
:-
Firstly Moulding or forming tyres for velocipedes or other vehicles whether
pneumatic, cushion or solid so as to give the outer surface the appearance of two
tyres but in reality only one tyre substantially as herein shewn and described with
reference to Figs. 1 and 2.
Secondly-Moulding or forming tyres for velocipedes or other vehicles so as to
give the outer surface the appearance of three tyres but in reality only one tyre
substantially as herein shewn and described with reference to Fig. 3.
:
Thirdly Moulding or forming tyres for velocipedes or other vehicles whether
pneumatic, cushion or solid so as to give the outer surface the appearance of two or
more distinct tyres substantially as herein described.
Fourthly The combination with a tyre substantially as herein shewn and
described with reference to Figs. 1 and 2 of a hollow rim formed concave on its
inner surface so as to fit the convex surfaces of the tyre.
:-
Fifthly The combination with a tyre substantially as herein shewn and
described with reference to Fig. 3 of a solid rim formed concave on the inner
surface of its edges so as to fit the convex surfaces of the tyre.
