PROVISIONAL SPECIFICATION.
A New or Improved Device for the Prevention of Puncture in
Pneumatic Tyres.
I, RALPH BASSETT of Cross Heath Newcastle, Staffordshire, Gentleman do
hereby declare the nature of this invention to be as follows:-
My invention relates to a new or improved device for preventing puncture in
pneumatic tyres and has for its object to provide a device which can be easily
applied and which will at once withdraw a nail, pin, or thorn that has caught in the
outer cover of the tyre, and thus prevent any damage being done to the air tube
of the said tyre.
In carrying my invention into practice, I provide a strip of metal, having
serrations or teeth if desired and of sufficient length to be bent over the tyre so as to
just allow the wheel to revolve freely without the device touching. Each end of
the band or strip is furnished with a steel clip by means of which it can be
attached to the fork.
This device or protector could be stamped out of steel or the clips could be
made separately and attached to the band or strip in any convenient manner.
Should any nail &c. enter the outer cover of the tyre it will be immediately caught
by the band or strip and withdrawn as the wheel revolves before it has time to
enter or in any way damage the air tube.
Dated this 16th day of October 1893.

COMPLETE SPECIFICATION.
A New or Improved Device for the Prevention of Puncture in
Pneumatic Tyres.
I, RALPH BASSETT of Cross Heath Newcastle, Staffordshire Gentleman 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:-
My present invention relates to a new or improved device for preventing damage
by puncture in the inner inflatable cases or air tubes of pneumatic tyres and the
object thereof is to provide a device which can be easily applied to the machine
and which will automatically withdraw a nail pin thorn or other similar obstacle
which has caught in the outer cover of the tyre and thus to prevent any damage
being done to the inner case or air tube of said tyre, to attain which I provide a
device and apply it to the machine substantially as described with reference to
the accompanying drawing which has to be taken as part of this Specification and
read therewith.
Fig. 1. is an isometric perspective view of my improved device applied to machine
in working position.
I provide a strip of metal A, having serrations or teeth a¹ on one edge thereof
as shown or plain as desired, and the said strip of metal A is of sufficient length

page_text: to be bent over the tyre T of machine so as to just allow the wheel to revolve
freely without the device actually coming in contact therewith.
Each end of the metal strip or band A is furnished with a steel clip or clips a³
by means of which it can be attached to the fork F.of machine.
It will be obvious that my improved device could be stamped out of one piece of
steel with the clips a' made therewith, or the said clips a could be made separately
and attached to the strip or band A in any convenient manner..
Should any nail thorn or other similar obstacle enter the outer case of the tyre T
it would be caught by the serrated or plain strip or band A and withdrawn
thereby automatically as the wheel revolved and before it had time to enter or in
any way damage or puncture the inner case or air tube.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is :
**
A device composed of a metallic strip A with or without serrations a¹ and having
clips a made with or attached thereto, applied in the manner substantially as
described and illustrated and used for the attainment of the object stated.
