Improvements in Pneumatic Tyres for Wheel Rims of Cycles and
other Vehicles..
I, CHARLES HOWARD CLOAD, of 1 Devonshire Terrace, Highbury Road,
Torquay, in the County of Devonshire, Plumber, do hereby declare the nature of
this invention to be as follows:-
My invention relates to improvements in pneumatic tyres for wheel rims of
cycles and other vehicles, which consists of an inflated endless tube with an outer
cover the edges of which engage with the well or groove constructed in my
wheel rim.
The outer cover on its periphery is provided with a series of ridges dieing away
into the cover diverging from a centre ridge both right and left which act as non-
slipping ribs, so that the periphery of the cover has no sharp edge to strike against
the brake. On each edge throughout of the india rubber cover are constructed
divided projections (triangular shape in section) each projection is about 1 inches
or more in length and the said projections are cased with sheet metal.
The object of the metal cased projections on each side of the cover is that when
the inflated tube is placed in position they shall be wedged or forced into the well
or groove of the rim of the wheel when the pneumatic tube is fully inflated.

Improvements in Pneumatic Tyres for Wheel Rims of Cycles and
other Vehicles.
I, CHARLES HOWARD CLOAD, of 1 Devonshire Terrace, Highbury Road,
Torquay, in the County of Devonshire, Plumber, 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 improvements in pneumatic tyres for wheel rims of
cycles and other vehicles, which consists of an inflated endless tube with an outer
cover the edges of which engage with the well or groove constructed in my
wheel rim.
And in order that my invention may be thoroughly understood I now proceed
to describe the accompanying drawing thereof, reference being had to letters and
figures marked thereon.
Fig. 1, is a section of tyre.
Fig. 2, is a front view of tyre.
Fig. 3. is a side view of tyre shewing the projections to fit in rim groove, also

page_text: the non-slipping ribs which die away into the cover, so that their front edge has a
grip on the road.
Fig. 4, is an enlarged section of the projection cased with sheet metal.
Fig. 5, is a section of the tyre fitted to the rim.
The outer cover a on its periphery is provided with a series of ridges b dieing
away into the cover a diverging from a centre ridge c both right and left which
act as non-slipping ribs, so that the periphery of the cover a has no sharp edge to
strike against the brake. On each edge throughout of the india rubber cover a
are constructed divided projections d (triangular shape in section) each pro-
jection d is about 1 inches or more in length and the said projections d are cased
with sheet metal e fixed thereto by rivets f.
The object of the metal cased projections d on each side of the cover a is that
when the inflated tube is placed in position they shall be wedged or forced into the
well or groove g beneath the flanges of the rim of the wheel when the pneumatic
tube is fully inflated.
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 :-
1. In pneumatic tyres for wheel rims of cycles and other wheels, the combina-
tion of the parts substantially as above described in this specification and illustrated
in the accompanying drawing.
2. In pneumatic tyres for wheel rims of cycles and other wheels, the combina-
tion of the outer cover a divided projections d sheet metal casings e fixed by
rivets for their equivalent, substantially as herein described and according to the
accompanying drawing.
3. In rims for tyres, the combination of the well or groove g and flanges on
each side of the groove g, substantially as herein described and according to the
accompanying drawing.
