PROVISIONAL SPECIFICATION.
Improvements in connection with Pneumatic Tyres for Velocipedes
and other Vehicles.
I, ALFRED THOMAS ANDREWS, of Tennant Street, Birmingham in the County
of Warwick, Cycle Maker do hereby declare the nature of this invention to be as
follows:
This invention has reference to an improved method for securing pneumatic
tyres in the rims of velocipede and other vehicle wheels, and my improvements
consist in enclosing all round both edges of an outer cover of a pneumatic tyre
short pieces of wire. Threaded onto the said short pieces of wire at suitable
distances apart is a suitable number of studs or links passing through holes formed
in the edges of the said outer cover and through corresponding holes formed in the
rim of the wheel. Each of the said studs or links is also provided at the end which
protrudes through the rim of the wheel with another hole for another piece or
pieces of wire to be threaded through, which said wire or wires pass all round and
bed against the outside of the said rim. I prefer to use a single piece of wire
passing all round on one side of the outer cover and on one side of the rim ; so that
when it is desirable to get at any part of the air tube I can withdraw one or more
of the short pieces of wire which bed against the rim and turn the outer cover over
without disturbing the wires on the other side of the cover and rim.
Dated this 24th day of November 1893.

Improvements in connection with Pneumatic Tyres for Velocipedes
and other Vehicles.
I, ALFRED THOMAS ANDREWS, of Tennant Street, Birmingham in the County
of Warwick, Cycle Maker 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 has reference to an improved method for securing pneumatic
tyres in the rims of velocipedes and other vehicle wheels.
In order that my invention may be clearly understood I have illustrated the
same on the accompanying sheet of drawings.
Fig. 1 is part sectional longitudinal view-and-
Fig. 2 is a sectional view of Fig. 1 taken through the line a-b.
A is the outer cover of the pneumatic tyre enclosed in the edges of which are a
number of short pieces of wire c. Threaded onto the said short pieces of wire c
at suitable distances apart are a number of studs or links B (see Fig. 3) passing
through holes formed in the edges of the said outer cover A and through corre-
sponding holes formed in the rim C of the wheel. Each of the said studs or links B
is also provided at the end which protrudes through the rim C with another hole
for another piece or pieces of wire d to be threaded through, which said wire or
wires d pass all round and bed against the outside of the said rim C. I prefer to
use a single piece of wire c passing all round on one side of the outer cover A and
a single piece of wire d' on the same side of the rim C, so that when it is desirable

page_text: to get at any part of the air tube I can withdraw one or more of the short pieces of
wire d and turn the outer cover A over without disturbing the wires d' and c¹.
Instead of employing the short studs B I may employ the T shaped piece as
shewn at Fig. 4 and dispense with the wires c and c¹. Or I may employ a split
T piece as shewn at Fig. 5. In this case I dispense with the wires c c and d d¹
and prevent the part e which protrudes through the rim C from slipping back by
means of the taper screw for equivalent (see Fig. 6) which expands the sides of
the said part e. It will be easily understood that any other means which would
expand the sides of the said part e may be used instead of the taper screw f.
Although I have shewn my invention as applied to velocipede wheels only it can
with equal advantage be applied to other vehicle wheels when pneumatic tyres
are used.
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 understood
that I do not confine myself to the precise details as herein shewn and described as
they may be varied without departing from the nature of my said invention but
what I wish to claim is :-
The means substantially as herein shewn and described or their equivalents for
securing pneumatic tyres to the wheels of velocipedes or other vehicles.
Dated this 24th day of August 1894.
