COMPLETE SPECIFICATION.
Improvements in Tyres for Cycle and other Vehicle Wheels.
I, CHARLES COLLETT, of 45, Baxendale Street, Hackney Road, Glass Fitter, 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 connection with tyres for the wheels
of cycle and other vehicles, and its object is to provide a tyre which will possess
the required resiliency without being in danger of puncture or injury.
I propose to form the tyre from a thin band of sheet steel or other suitable metal
of channel form in cross section. The edges are bent outwards slightly and are
preferably formed with serrated edges.
The rim is provided with channelled edges to receive the said flanges and within
the channels of the rim, strips of rubber or other suitable resilient material are
fitted in which the edges of the flanges are embedded. The tyre is thus secured
in a bed of rubber at each side so that both the resiliency of the rubber and the
serrated edges of the steel is employed.
The surface of the tyre is roughened by punching-out small depressions around
the tread, the steel however not being completely punched through.
In order that the invention may be more clearly understood, reference is had to
the accompanying sheet of drawings, in which Fig. 1 is a cross section of one form
of tyre constructed according to my invention. Fig. 2 is a section of a slightly
modified form, and Fig. 3 is a detail view showing the method of roughening.
Referring to Fig. 1, A is the tyre which as shown is of channel or U form in
cross section, the surface being rounded. The edges are serrated and bent out
slightly to form the flanges a by which the tyre is secured. The rim B is formed
with the channelled edges b within which are fitted rubber bands or strips C.
These serve to receive the flanges az and to secure the tyre in place.
Referring to Fig. 2, A¹ is the tyre which is of V shape in cross section, the
corner however being rounded. The arrangement is otherwise exactly similar
to the first, the tyre being fitted to the rim in the same manner.
As shown in Fig. 3 the tread of the tyre is roughened by means of depressions a¹
heing pressed out from the surface so that projections are formed at the outside.
These small knobs or projections give a good grip on the ground and prevent any
danger of side slip.
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) An improved tyre for cycle and other vehicle wheels, formed from a band of
sheet metal of channel form in cross section and secured to the rim at the edges,
substantially as described and for the purposes specified.
(2) The improved tyre for cycle and other wheels formed from a band of spring
metal of channel shape in cross section and provided with serrated flanges secured

page_text: to the rim by means of channels in the latter and rubber strips within the said
channels, substantially as described and for the purposes specified.
(3) An improved tyre for cycle and other wheels formed from a band of spring
metal of channel shape in cross section and provided with flanges on each side
roughened by means of small projections caused by bulging out the metal, the
tyre being secured to the rim by channels in the latter and rubber strips within
the said channels, substantially as described and shown and for the purposes
specified.
Dated this 26th day of November 1897.
