ROBERT JAMES WHITE 1564 Blackstock Road Finsbury Park London N.
Wine and Spirit Merchant 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:-
The object of this invention is to be able in the event of punctures easily to
detach or replace the part punctured by a length carried or kept for the purpose,
and also to be able to replace the length if a bad gash, at about one third or fourth
the cost of a whole new inner tube.
My invention is as follows,
A hollow bag, or bags a made of india rubber,.tubular form, with closed ends B,
rounded or flat, moulded, and joined in centre c or otherwise suitably closed, one,
two, three, four, or more such bags placed in the hollow or groove of the rim d of
a wheel or wheels the ends B touching each other, near each end B is a small
rubber communicating tube e let in and fixed to the main bag or bags a and
conducted through a necessary number of ducts in the rim d close enough together
so that the communicating tubes e near the ends B of the bag or bags a can easily
be attached to or detached from the communicating tubes e nearest in the other
section or adjoining end or ends B of bag or bags a at the inner side of rim d
towards the hub G by male and female joints H or other fastenings most suitable,
thus interlacing the rim d or wheel with tubes and giving the gas or air under
pressure free communication in one bag a with closed ends B, or any number of
bags a with closed ends B.
A non return valve i (detachable) is attached to either one of the small
communicating tube joints H for the purpose of inflating the bags a which are
fill together

page_text: The bags a are kept in their place on the rim d by a detachable cover J of india
rubber, canvas, or other material.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1st. Tubular detachable bag or bags with closed ends, made of india rubber,
placed in the hollow or groove of the rim of a wheel or wheels, with small rubber
tubes attached which pass through the rim and join on the inner side of the rim by
detachable joints, so that all the parts can be inflated or deflated at one time by
means of a non return valve attached to either of the small rubber tubes, or sections
of the tyre taken off and replaced at pleasure.
