PROVISIONAL SPECIFICATION.
An Improved Air Tyre and Method of Fixing same to Cycle
Wheels.
I ALBERT EDWARD PAYER of 28 Rendezvous Street Folkestone Kent Builder
& Contractor do hereby declare the nature of this invention to be as follows:-
:-
My invention being an improvement in air tyres which are inflated by pressure
of compressed air. My plan is to employ layers of canvas and rubber stretching
round the air tube and hooking onto the rim of wheel by using metal hooks,
studs, or buttons which will be fixed into the rim so that when the air tube is
deflated the outside covers can be unhooked at once and in the case of a puncture
the inside tube can be repaired and replaced with the least possible delay. As
the method of hooking on to the rim can be used with advantage in combination
with other air tyres I wish it to be especially protected.

COMPLETE SPECIFICATION.
An Improved Air Tyre and Method of Fixing same to Cycle
Wheels.
I ALBERT EDWARD PAYER of 28 Rendezvous Street Folkestone in the County
of Kent Builder & Contractor 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 :-
This invention relates to improvements in that class of wheel tyres which are
formed hollow and inflated with air or gas under pressure the object of my
improvement being to obtain the simplest possible construction and greater
elasticity than heretofore and the quickest possible means for allowing the tyre
to be removed for repairs.
According to my invention the coverings placed around the air tube are
hooked onto the metal rim of wheel by means of metal hooks, studs, buttons,
pins, eyelets, or by means of slots cut out of or made on the metal rim of wheel
at distances of about 1 in. apart and the coverings placed around the air tube
to have metal lined holes in each edge of same for the purpose of hooking over
the said metal hooks studs pins or buttons or into the said eyelets or slots by
means of hooks or metal tee pieces fixed on each edge of the outside covers.
According to my invention the outside coverings of the air tyre are to be fixed
cnto the metal rim of any kind of wheel by means of a hooking movement.
And my invention consists in using the compressed air or gas inside the air
tube in its action of expanding the tyre and in its action of stretching the outside
coverings to fix them in a firm and safe manner on the hooks which are fixed
into the rim of wheel and that the action of the compressed air or gas inside
the air tube is my method of securing the tyre safely onto the rim of wheel.
My invention provides that the air tube shall not come into immediate contact
with the edges of rim of wheel whereby the said tube would be liable to injury.
I secure lappets or flaps of leather, canvas or other suitable material on each edge
of the metal rim which said lappets are secured in such a manner that they will
tend to counteract any lateral expansion of the said tube and prevent the said air
tube from seaming or cutting itself on the edge of metal rim.

page_text: And the further part of my invention consists of metal hooks studs pins or
buttons fixed into the rim of wheel in such a manner that in case of a puncture or
leak in the air tube and the tyre collapseing the outside covers cannot drop off
or become unfixed by their own action.
My invention also consists in providing an extra outer covering of rubber lined
with canvas which can be placed over the outer layers before mentioned to provide
for heavy road work or long distance riding and the said extra. outer covering
to be hooked onto the metal rim of wheel so that it can be removed when the tyre
.is deflated.
In order that my invention may be fully understood I will proceed to describe
the drawings annexed but I do not limit myself to any measurements.

said cover comes in contact with the ground and is also hooked onto the metal rim
of wheel. D. D. indicates the two lappets formed in one piece and cemented to

the eyelet holes lined with metal on each edge of the outside covers.
Figure 3 represents the different kinds of hooks, studs, pins, buttons, eyelets or
metal tee pieces that would be used for fixing into metal rim or on each edge of the
outer coverings of the air tyre.

of wheel. A indicates outside cover. B indicates narrow pieces of leather fixed
on top of each edge of outside cover. C indicates eyelet holes. D indicates the
hooks. E indicates the air valve. F indicates metal rim.
Figure 5 represents a section of the outside cover. A A indicates two eyelet
holes. B B indicates two pieces of leather. C indicates layer of india-rubber.

Figure 6. represents a piece of the outside cover laid out flat. A. A. A. indicates
three eyelet holes. B indicates a piece of leather. C indicates india-rubber which
comes in contact with the road.
Figures 8. 9. 10. 11. 12. 13. 14. 15. 16. 17. 18. 19 represents different shapes of
metal rims showing how slots, hooks, eyelet studs buttons or pins may be adapted
to their different shapes as required.
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
First. The construction of a tyre formed of coverings of canvas and india-rubber
which can be fixed onto the rim of wheel by means of metal hooks studs buttons
pins eyelets or slots cut out of or formed on the rim of wheel by means of a
hooking movement as hereinbefore described and shewn in the accompanying
drawings.
Second. The construction of an air tyre formed of coverings of india-rubber and
canvas placed around the air tube which said covers shall be fixed onto the metal
rim of wheel by means of a hooking movement as hereinbefore described.
Third. The construction of an air tyre in which the action of the compressed air
inside the air tube shall be used as my method of securing the tyre safely onto the
rim as hereinbefore described and illustrated by Figure 1. & 2. of the accompanying
drawings.
Fourth. The construction of an air tyre formed of covers made of canvas and

page_text: india-rubber fixed onto the rim of wheel in such a manner that in case of a collapse
of the tyre the covers cannot drop off or become unfixed without the aid of the
hand as hereinbefore set forth.
Fifth. The construction of an air tyre which may be adapted to any sectional
shape of rim substantially as herein before set forth.
Sixth. The construction of an air tyre on which an extra outer covering can be
placed and can be hooked over the other covers and used for heavy road work and
can also be removed when required as hereinbefore described.
