PROVISIONAL SPECIFICATION.
An Improvement in Inflated Cycle Tyres, Foot-balls, and other
Apparatus requiring Inflation.
JOSEPH ROBINSON 25 Queen's Arcade Belfast Hair-dresser do hereby declar
the nature of this invention to be as follows:
To prevent puncture in cycles or in any other apparatus requiring inflation, I
make the tube or bag about double the size usually done. When a nail or the like
pierces the outer covering, it will only push in out of its way the inner tube or
bag & in this way I can use much thinner rubber or canvas or other material for
either the outer covering or inner tube or bag.

An Improvement in Inflated Cycle Tyres, Foot-balls, and other
Apparatus requiring Inflation.
I, JOSEPH ROBINSON late of 25 Queen's Arcade but now of 53 Donegall
Place in the City of Belfast and County of Antrim, in Ireland, Hair-dresser, 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 invention relates to the construction of cycle tyres, foot balls, and other
apparatus or articles which are rendered elastic by inflation and require protection
against puncture by running over or otherwise coming into contact with nails or
other hard, sharp pointed or edged objects whereby the air tube or bag would be
pierced and the compressed air enabled to escape.
For this purpose I enclose within the ordinary outer covering of the tyre,
football or other apparatus or article referred to an impervious air tube or bag
which is of much larger size or caliber than is usually employed for the purpose
and lies in folds or plaits within the outer covering instead of being in complete
contact with it throughout its entire inner surface and so that the fold or
plait will shift and avert resistance, allowing any part of the wall of the
inflated tube or bag to stretch and yield or be pushed aside out of the way
when a nail or other like object may have pierced through or penetrated the outer
covering.
In the application of my invention to the tyres of cycles and other like
machines I prefer to use an air tube of about double the caliber or bore commonly
employed but in the case of footballs and similar apparatus I may use a propor-
tionably smaller air bag according to the nature of the ground to be played upon
or the quality or material of the covering in which it is to be enclosed.
The covering of the tyre or foot ball may be such as is commonly employed for
those purposes respectively and the air tube or bag may likewise be of the ordinary
description and will be inflated in the usual way but either or both the covering

page_text: and the tube or bag may be of lighter build than those at present in general use
and I may construct them from canvas, silk or even paper-such material being
prepared for the air tube or bag with a coating of rubber or other impermeable
solution.
It is obvious that I may apply my invention to other pneumatic wheels and
apparatus or articles than those I have above specifically mentioned and may also
vary the proportionate sizes without departing from the character thereof.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I would have it to be
understood that I do not claim as of my invention or the exclusive use of pneumatic
tyres, footballs or like apparatus or articles except when the same are constructed
specially and employed in the manner I have indicated nor do I claim any means
of inflating such air tubes or bags or of placing or securing my tyres upon the
wheels of cycles or other vehicles or the use of any of the separate parts of such
tyres and wheels but I declare that what I claim is.
1. The use, in pneumatic tyres, footballs and other apparatus or articles requiring
inflation and protection against puncture, of an inflated tube or bag of large
relative caliber constructed, and employed in the manner and for the purposes
herein before described.
2. The combination and arrangement of parts constituting my improved air-
inflated apparatus constructed and employed substantially in the manner and for
the purposes hereinbefore described.
Dated this 10th day of December 1894.
