Improvements in the Method of Construction of Cycle Wheels, Tyres,
and the like.
We, SYDNEY RICHARD MALLINSON, of Hall Farm, Rawdon, Civil Engineer, and
JESSE COOKE, of Highfield, Keighley, Wool Comber, also JAMES WOODHEAD, of
Farnley, near Leeds, Colliery Proprietor, all of the County of York, do hereby
declare the nature of this invention to be as follows:-
This invention has for its object the construction of cycle wheels, tyres and the
like, in such a manner, as to gain greater rigidity and strength in the wheel &
tyres, also greater resistance to collapse in the tyres themselves, enabling a greater
load to be carried for a given quantity of material, thus effecting a reduction in
weight, and adding to the strength of the wheel.
We accomplish our object in the following manner.
We substitute a double U
or V-shaped section in preference to the ordinary or single rim as is commonly
used, duplicate tyres, are placed in the sections, of a smaller diameter than is neces-
sary where a single tyre is used. The small tubes being better able to withstand
the pressure than the large tyres at present in use.
The spokes from the axle are placed diagonally across from one side of the
axle to the opposite side of the rim, forming a triangular structure, thus giving
greater rigidity to the wheel and security against collapse. The spokes are crossed
alternately round the circumference of the rim.
Either cushion, or pneumatic tyres may be used, Where pneumatic tyres are
used the air tubes are connected by a pipe which allows of the air pressure being
equalised in each tube, or in case of puncture and collapse of one tube, a ball valve
is provided which closes the air from escaping from the unpunctured tube, thus
ensuring a double security from collapse.

Improvements in the Method of Construction of Cycle Wheels, Tyres,
and the like.
We, SYDNEY RICHARD MALLINSON, of Hall Farm, Rawdon, formerly of 144,
Spring Bank, Hull, Civil Engineer, and JESSE COOKE, Highfield, Keighley, Wool
Comber, also JAMES WOODHEAD, of Farnley, near Leeds, Colliery Proprietor, all
of the County of York, do hereby declare the nature of this invention, and in what
[Price 8d.1

page_text: manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:—
The object of this invention is to construct cycle wheels, and the like combined
with the tyres as to gain greater strength and rigidity in the wheel & tyres, also
greater resistance to collapse in the tyres themselves.
In describing our invention in detail reference is made to the accompanying
drawings in which Fig. 1, represents a half section of a wheel constructed accord-
ing to our invention.
Fig. 2, is an enlarged section (in detail) showing the rims and tyres.
Fig. 3, is an enlarged section (in detail) showing a modification of the rims and
tyres.
Fig. 4, is a section showing the arrangement of valve for inflating the tyres.
From the axle A the spokes, S, are arranged diagonally across from one side
of the axle A, to the opposite side of the rim, B and 13, in such a way as to form a
triangular frame work. Inside the rims B and B¹, are placed pneumatic or cushion
tyres C¹ and C¹ which in the case of pneumatic tubes being used a protecting
shield D is provided which is fixed to the rim by a projection P, engaging with a
corresponding notch in the rim of the wheel as shown at E.
The shield or covering D, above the projection is run out to a thin edge as shown
at F which on inflation of the tubes, assists to hold the shield or cover, D, in
position.
To minimise the liability of puncture a cushion tyre G is constructed along with
the shield or covering, D, in the manner shown in Fig. 2, and 3, so as to raise the
pneumatic tubes clear of the road.
The two pneumatic tubes are connected by a valve V which allows the pressure to
equalise itself in both tubes, as in going round a curve, or over uneven ground,
where the tendency would be to throw the weight on to one tube only.
By the arrangement of the spokes and construction of the double rim as show, a
much stronger wheel is produced in proportion to the amount of material used.
Also by the arrangement of the rims in combination with the tyres and shield
the risk of puncture & collapse is removed, as the cushion tyre in combination with
the shield raise the pneumatic tubes clear from the road.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:-
No. 1 A wheel in which the spokes are arranged to engage with a special rim
in the manner as shown and described.
No. 2 A double U or V shaped rim in which the pneumatic tubes or cushion
tyres are placed, substantially as shown and described.
No. 3-A wheel, in which the spokes and rims are arranged as herein described
and set forth.
