Improvements in Attachments for Fastening Pneumatic Tyres to the
Rims of the Wheels of Bicycles, Tricycles, or other Vehicles.
LEWIS OWEN MICHAEL, Commercial Traveller, formerly of 7, Hugh Villas,
Hugh Road, Small Heath, Birmingham, and now of 54, Tewkesbury Street,
Cardiff, do hereby declare the nature of this invention to be as follows.-
My invention is an improvement, as the strips used do not protrude through
the canvas, and the edges being clamped together allow the tyre to be fixed
to all kinds of rims as the tyre cannot grip under the internal edges of concave
11m8.
In carrying my invention into effect I first prepare the outer covering of
canvas by stitching or otherwise making pockets in the edges sufficiently wide
to allow strips of steel or other material to be inserted therein. These strips
may consist of any number sufficient to go all around and allow the ends to
overlap each other, in the centre of the strip an eyelet or other fastening secures
it to the canvas, thus allowing both ends to slide freely upon the others
near the centre of one of the strips on each side I cut a hole of sufficient size
to allow the valve of the au tube to pass through
And
I may also use one strip of sufficient length to go all around, and the ends
having slots cut lengthwise in them of sufficient width to allow the air valve
to pass through, overlap each other and slide upon each other at that point
I next place the air tube in the cover and lap the one edge upon the other
passing the valve of the air tube through the hole or slot I then clamp the
edges together with clips which grip both sides tightly thus holding_them
firmly upon each other
These clips may be made in various forms, or I may
use screws or other devices so as to secure the strip edges firmly upon each
other thus forming a complete tube. The outer covering of rubber I solution
on in the ordinary way. The tyre is next placed upon the rim, the bands in
the edges being fimly pressed into the bottom, and the air tube inflated, the
all pressure causes the tyre to contract in the rim the strips slide inwards upon
each other and secures the tyre to the rim.

LEWIS OWEN MICHAEL, Commercial Traveller, 54, Tewkesbury Street, Cardiff,
do hereby declare the nature of this invention and in what manner the same

page_text: is to be performed, to be particularly described and ascertained in and by the
following statement:-
My invention has for its object the clamping of the edges of the cover of a
pneumatic tyre one upon the other, so as to allow the tyre to be fixed to all
kinds of rims.
In carrying my invention into effect, I first prepare the outer covering of
canvas by stitching or otherwise making pockets in the edges sufficiently wide
to allow strips of steel or other material to be inserted therein These strips
may consist of any number sufficient to go all around and allow the ends to
overlap each other In the centre of each strip an eyelet or other fastening
secures it to the canvas thus allowing both ends to slide freely upon the others
Near the centre of one of the strips on each side, I cut a hole of sufficient size
to allow the value of the au tube to pass through Attached to the steel strips
of one edge are clips the upturned edges of which project slightly above the
steel strips, sufficient only to clip the other edge when laid upon it, thus keeping
the two edges square one upon the other.
The outer covering of rubber I solution on in the ordinary way To attach
the tvie to the rim I first insert the air tube, then placing the one edge upon
the other press them firmly into the rim, the air tube being inflated the air
pressure causes the tyre to contract in the rim, the strip slide inwards upon
each other and secures the tyre to the rim.
I will describe my invention by referring to the accompanying drawings which
shews the tyre in unfixed section, and also section fixed in rim.
In the unfixed section A shows the flat steel band in one edge of the cover,
B shews the flat steel band in the other edge, and C the clip in which both bands
are to lie one upon the other
In the section shewn fixed in the rim, C is the clip, shewn as resting upon the
rim, B the edge of the tvre, with flat steel band lving in bottom of the clip A
the other edge of the tyre with its flat steel band lving upon B. The air
pressure of inner tube presses all down in bottom of rim
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 18:
The use of clips to keep the edges of the cover one upon the other as herein-
before set forth.
