PROVISIONAL SPECIFICATION.
Improvements in or relating to the Attachment of Tyres to the
Rims of Bicycles and other Velocipedes.
I FREDERICK WILLIAM HIGGINBOTHAM cf Glennaurice, Saint Lawrence
Road, Clontarf in the County of Dublin, Ireland, Student of Engineering, do
hereby declare the nature of this invention to be as follows:-
-
This invention relates to that class of pneumatic tyres which are held on to the
rim by two wires fixed round each edge of the outer covering, and has for its object
to keep these wires secured in position, whether the air bag is inflated or not.
According to this invention I fix buttons or knobs at the ends of each wire, which
buttons or knobs pass through slots formed in the rim, and the wires also pass
through other slots formed in four flaps pivotted on the inner surface of the rim ;
and I provide a suitable catch device to securely hold the flaps in position by
which means the wires are securely held to rim whether the tyre is inflated or not.

Improvements in or relating to the Attachment of Tyres to the
Rims of Bicycles and other Velocipedes.
I FREDERICK WILLIAM HIGGINBOTHAM of Glenmaurice, Saint Lawrence
Road Cloutarf in the County of Dublin, Ireland, Student of Engineering, 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 relates to that class of pneumatic tyres which are held on to the
rim by wires fixed round each edge of the outer covering and has for its object
to keep these wires secured in position whether the air bag is inflated or not.
According to this invention I fix buttons or knobs at the ends of each wire
which buttons or knobs pass through slots formed in the rim and the wires also pass
through other slots formed in four flaps (pivotted), and I provide a suitable catch
device to securely hold the flaps in position by which means the wires are securely
held to rim whether the tyre is inflated or not.
And in order that my said invention may be better understood I will describe the
same with reference to the accompanying sheets of drawings in which the same
letters are employed to denote the same parts in all the views:-
a shews the outer covering having wires bb as shewn in Figs. 3, and 4.
The ends of these wires are provided with knobs c c as at Figs. 2 and 4 or these
ends may be hooked as at Figs. 1, 3 and 7 d d are pivotted flaps or levers these
may be either on the inside of the rim e as shewn at Figs. 1, 2, 3, 4, or on the
outside of same as shewn at Figs. 10 and 11.
Instead of wires b b I may have bands ff in which case the ends of said bands
would be provided with slots gg as shewn at Figs. 8 and 9 in which views the
ends of said bands are shewn detached; it will be also seen that the ends of

When the flaps or levers d d are used inside the rim slots are made in said r

provided in the said flaps for the ends ce of the wires b. b. to take or ho

Slots or holes, 1, 1, are al
In order to tighten the wires bb or bands f. f. round the rim the said wire
or bands being in the position shewn in Figs. 2, 4, 7, 9 and 11. it is simpl
necessary to press down the flaps d, d, by which they become extended and assum
the position shewn at Figs. 1 and 3 and by reason of the ends of the wires bein
crossed as shewn at Figs. 1, 2, and 7 they will be drawn in opposite directions and
thus tighten same round the rim and such tension will be retained when the flaps d
are in the position shewn at Figs. 1 and 2.
are employed as the tooth or projection h on the one end of band passes through the
The same action applies when bands f
slot g in the
opposite end of band so that when the flaps d d are extended as before
described (one Hap taking against the tooth h and the other flap against hook i) the
two ends of the band will be drawn in opposite directions and thus tighten the
band fround the rim.
The pivotted flaps d d may be actuated either by means of screw m and nut n or
by pressure exerted ou the said flaps by the hand or otherwise.
Fig. 5 shews section of a tyre complete with my invention adapted to the outside
of rim and Fig. 6 shews the two sides of cover a held in position by means of one
band only, shewn fully in Fig. 7. in consequence of the formation of the rim.
oo are thickened edges to the outer covering.
Fig. 10 shews hollowed flaps or levers d with holes p in which the hooked ends of
wires engage so as to keep the crossed wires from coming in contact with the air
bag. Fig. 11 shews another method of using the pivotted flaps d in which the
knobs or hooks: c engage in the claws y, on ends of flaps d these claws sliding in
slots in flange of rim e such claws being provided with heads on other side of rim
the pivots is prolonged slightly so that when the flaps are pressed down into 3
position this shall engage in hole t in rim e and is retained there by the pressure of
the air in tyre.
Instead of having four pivotted flaps I may only have two when one edge of
the covering a is permanently fixed to the rim by a wire or otherwise.
Having now particularly described and ascertained the nature of my said inven- 3
tion and in what manner the same is to be performed I declare that what I
claim is :-
In pneumatic tyres the pivotted flaps or levers in combination with wires or bands
u or on the edges of the outer covering substantially as and for the purpose
described and shewn on the accompanying drawings.
