Improvements relating to Pneumatic and other Elastic Tyres, and to
Brakes for use in connection therewith.
We, JOHN RIDLEY TEMPERLEY, and SIDNEY MANTHORP COCKBURN, both of
72, Bishopsgate Street Within, in the City of London, Engineers, do hereby declare
the nature of this invention to be as follows:
-
Our invention relates to pneumatic and other elastic tyres for bicycles and other
velocipedes or vehicles, and to brakes for use in connection therewith.
According to one part of our said invention, we provide on each side of the
exterior of the tyre, a strip or band of canvas or other suitable material which is
either cemented or otherwise caused to adhere to the tyre or is secured thereto
by vulcanizing during the manufacture thereof, and we coat or treat the said
bands or strips with beeswax or similar material.
By this means we provide for enabling a brake to be applied to the sides of the
tyre without liability to seizing of, or injury to, the surface of the tyre, by the
friction and attrition caused by the application of the brake. The said strips or
bands can be made, if desired, with a suitable proportion of their threads of wire or
other material capable of resisting wear.
With a tyre so constructed, the speed of the vehicle can be very easily and con-
veniently retarded, when necessary, by placing the feet on the foot-rests and bearing
with the heels laterally against the tyre, the beeswax or similar material prevent-
ing undue friction or seizing between the surfaces in contact.
We can, however, provide a brake, if desired, so arranged that it can be caused
to press against the sides of the tyre. For this purpose we prefer to employ the
improved brake hereinafter mentioned.
This brake comprises blocks of wood, leather, vulcanite, or other suitable
material, each mounted at one end of a lever arranged substantially parallel to
the rim of the wheel and pivoted at or near the middle of its length to the fork of
the velocipede or to any other convenient part of the frame. In order to press the
brake-blocks against the sides of the tyre, the other ends of the two levers are
coupled to the ends of a toggle-joint, the central pivot of which is arranged to be
operated by means of a brake-rod passing through the steering-post and connected
with a brake-lever on the handle-bar, or in any other suitable manner.
We prefer to make the aforesaid strips or bands of such width that they will
extend from the non-slipping tread of the tyre to and a short distance within the
wheel-rim.
In making such strips or bands for attachment to existing tyres, we find it
odvantageous to provide them with a coating of India-rubber or to otherwise pre-
pare them in such a manner that they can be readily applied to the tyre, being
caused to adhere thereto by means of India-rubber solution or other suitable
cement.

Improvements relating to Pneumatic and other Elastic Tyres, and to
Brakes for use in connection therewith.
We, JOHN RIDLEY TEMPERLEY and SIDNEY MANTHORP COCKBURN, both of
72, Bishopsgate Street Within, in the City of London, Engineers, 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:-
Our invention relates to pneumatic and other elastic tyres for bicycles and other
velocipedes or vehicles, and to brakes for use in connection therewith.
According to one part of our said invention, we provide on each side of the
exterior of the tyre, a strip or band of canvas or other suitable material which is
either cemented or otherwise caused to adhere to the tyre or is secured thereto
by vulcanizing during the manufacture thereof, and we coat or treat the said
bands or strips with beeswax or similar material.
By this means we provide for enabling a brake to be applied to the sides of the
tyre without liability to seizing of, or injury to, the surface of the tyre by the
friction and attrition caused by the application of the brake. The said strips or
bands can be made, if desired, with a suitable proportion of their threads of wire or
other material capable of resisting wear.
.
With a tyre so constructed, the speed of the vehicle can be very easily and con-
veniently retarded, when necessary, by placing the feet on the foot-rests and bearing
with the heels laterally against the tyre, the beeswax or similar material prevent-
ing undue friction or seizing between the surfaces in contact.
We can, however, provide a brake, if desired, so arranged that it can be caused
to press against the sides of the tyre.
In the accompanying drawing we have shown how our said invention may be
conveniently and advantageously carried into practice.
.
Figure 1 is a side elevation of a portion of a bicycle with our invention applied
thereto, and
Figure 2 is a front elevation, partly in transverse section on the line,
Figure 1.
A is a single-tube pneumatic tyre; B, B are the bands or strips of waxed canvas
or similar material, one of which is provided along either side of the said tyre. The
said bands or strips are cemented into the tyre or secured thereto by vulcanizing
in the course of manufacture, and form suitable surfaces against which to apply
a brake. The said tyre is preferably made with overlapping pieces A¹ of India-
rubber to cover the upper edges of the said bands or strips.
On the front fork of the machine, in the arrangement shown, are pivotally
mounted brake-shoes D one on either side of the tyre A, which brake-shoes are
adapted to bear against the bands or strips B when the brake is applied as herein-
after described.
For this purpose, the said brake-shoes D are provided with inwardly-extending
arms D' having rounded ends D which fit into sockets E formed at the lower end
of the brake-rod F. When the rod F is raised by the usual brake-lever or in any
other suitable manner, the shoes D will be pressed against the bands or strips B at
the sides of the tyre A and the motion of the vehicle will thus be retarded.
It is obvious that, if desired, other suitable mechanism can be employed for
pressing the brake-shoes against the bands or strips B at the sides of the tyre. Or,
as above stated, a brake can be dispensed with and the motion of the vehicle be
retarded by pressure of the rider's heels against the said bands or strips B.
It is evident, moreover, that, if desired, the said bands or strips can be applied

page_text: to other forms of tyres, and to the covers or sheaths of tyres of the kind in which
an inner inflatable tube is used.
We prefer to make the aforesaid strips or bands of such width that they will
extend from the non-slipping tread of the tyre to and a short distance within the
wheel-rim.
In making such strips or bands for attachment to existing tyres, we make them
of circular shape to correspond to the configuration of the tyre, and we find it
advantageous to provide them with a coating of India-rubber or to otherwise prepare
them in such a manner that they can be readily applied to the tyre, being caused
to adhere thereto by means of India-rubber solution or other suitable cement.
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:-
First. A pneumatic or other wheel-tyre provided on either side thereof with a
band or strip of waxed canvas or similar material to form a suitable surface
against which to apply a brake, substantially as herein before described.
Second. The combination of a wheel provided with a pneumatic or other tyre
having on either side thereof a band or strip of waxed canvas or similar material,
and a brake so constructed and arranged that, when in operation, the brake-shoes
thereof will bear against the said bands or strips, substantially as hereinbefore
described.
.
Third. A band or strip of waxed canvas or similar material of the shape herein-
before described and adapted to be readily applied and caused to adhere to the
side of a pneumatic or other tyre, for the purpose above specified.
