PROVISIONAL SPECIFICATION.
Improvements in and relating to Tyres for the Wheels of Cycles
and other Vehicles.
WILLIAM MCPHAIL, Roseville Wicklow, Ireland, Printer do hereby declare
the nature of this invention to be as follows :-
A grooved india rubber hollow tyre and a grooved metal rim in two parts viz.-
tyre about 2" in diameter with hollow, for compressed air, about 17 by 1}";
the solid part from 1% to ", and grooved on either side to allow of its being
grasped by the bent in grooves of metal. The rim is made in two parts, the
larger part with buttons on one side and bent in grooves at bottom edge of the
other side, the smaller part with button holes and grooved at bottom edge of
same. The spokes are screwed into a small socket attached to the rim. The
tyre can be firmly secured in the rim in less than a minute; no injury to the
resiliency of the tyre, by puncture, can possibly happen, and no pumping of air
necessary after the tyre leaves the hands of the manufacturer.

Improvements in and relating to Tyres for the Wheels of Cycles
and other Vehicles.
I, WILLIAM MCPHAIL, of Roseville, Wicklow, Ireland, Printer, 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 and relating to tyres for the wheels of
cycles and other vehicles, which consists of a grooved india rubber hollow tyre,
and a grooved metal rim in two parts which are fastened together with buttons,
bolts and nuts or the like.
And in order that my invention may be thoroughly understood, I now proceed
to describe the accompanying drawing thereof, reference being bad to letters and
figures marked thereon.
Fig. 1, represents a transverse section of the india rubber tyre and the grooved
metal rim in two parts and fastened together with oval buttons.
Fig. 2, is a transverse section of an india rubber tyre of an alternate pattern.
Fig. 3, is an elevation of a part of the rim of the wheel and the tyre, this figure
is broken off for convenience.
The india rubber tyre a is constructed with a longitudinal opening b for
compressed air or otherwise, this said india rubber tyre a is grooved on either side
as in Figs. 1, and 2, to allow of its being grasped by the bent in or curved grooves
of both parts c and d of the metal rim of wheel.
The rim of the wheel is made in two parts, viz.-the larger or main part c with
oval or any other shaped buttons e on one side as in Fig. 1, and bent in grooves at

page_text: the bottom edge of the other side; the smaller or movable part of rim dis
provided with oval button holes f either longitudinally or transversely, this said
movable part of rim d is grooved at bottom edge to correspond with that of the
main part e as in Figs. 1, and 3.
The spokes may be screwed into a socket attached to the rim of a wheel, or
fixed in any other well known method.
Either of the pattern india rubber tyres may be firmly secured in the rim in less
than a minute, and no injury to the resiliency of the tyre by puncture can possibly
happen.
It will be understood that the foregoing is given for illustration, and that the
parts, shapes and materials may be varied in many ways within the scope of my
invention.
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 is:-
1. In india rubber tyres for the wheels of cycles, the combination of the hollow
india rubber tyre with grooves on either side to allow of its being grasped by the
bent in grooves of a metal rim of a wheel, substantially as herein described and
according to Figs. 1, and 2, of the accompanying drawing.
2. In metal rims for the wheels of cycles made in two parts, the combination of
the larger or main part c with buttons e on one side and bent in grooves at bottom
edge of the other side with the smaller or movable part d with button holes f
longitudinally or transversely, and-grooved at bottom edge to correspond with that
of the main part of the rim, substantially as herein described and according to
Figs. 1, and 3, of the accompanying drawing.
