Improvements in the Construction of the Tyres of Cycles or other
Vehicles.
I, JOHN EDWARD WALSH, Mechanical Engineer, of The Woodlands, Lightcliffe,
near Halifax, in the County of York, do hereby declare the nature of this invention
to be as follows:
1
The object of my invention is to construct the tyres of cycles and other vehicles
with the required resiliency but without any possibility of injury by puncture,
at the same time to be light, durable, and readily and cheaply renewed or replaced
when worn out.
I employ a band or bands of tempered steel cards or pins upon cloth, rubber,
leather, or other suitable foundations or backs; these bands are fixed around the
periphery of the rim of the tyre, either with the pins downwards upon or towards
the face of the rim, or the back of the cards may be upon the face of the rim,
or both may be employed with their teeth or pins intermingling, or with the band
or bands of cards may be employed and inflated intermediate or bottom pneumatic bed.
The teeth or pins of the card may be of various widths, lengths, and strengths as found
suitable for the class of wheel required, or in place of the card bands, cork cylinders
solid or hollow or blocks of cork at intervals may be used loose or strung upon a
core of wire band or other suitable material between the pneumatic bed and the
outer cover, so that the pneumatic bed cannot be punctured. The cork cylinders
or blocks are saturated with, oil, glycerine or the like to add to their resiliency.

Improvements in the Construction of the Tyres of Cycles or other
Vehicles.
I, JOHN EDWARD WALSH, Mechanical Engineer, of The Woodlands, Lightcliffe,
near Halifax, in the County of York, 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:-
The obiect of my invention is to construct the tyres of cycles and other vehicles,

page_text: at the same time to be light, durable, and readily and cheaply renewed or replaced.
I employ a band or bands of tempered steel cards, staples, or pins, set upon
cloth, rubber, leather, or other suitable foundations or backs, these hands are fixed
around the periphery of the inflated tube, either with the pins downwards or upwards
towards the cover, preferably the latter, and so form a shield armour or protection
for the pneumatic tube.
For heavy tyres for vehicles a double strip of cards may be employed, with their
teeth or pins intermingling, and with a rubber cover above the same.
Or with the band or bands of cards may be employed an inflated intermediate
or central pneumatic tube or bed.
The teeth, staples, or pins of the card may be of various widths, lengths,
strengths, and shapes as found suitable for the class of wheel required.
The tempered steel card teeth may be tinned to prevent possibility of corrosion
they will then probably last as long as the machine.
DESCRIPTION OF DRAWINGS.
Fig. 1 is an elevation in section of my improved puncture proof tyre.
Fig. 2 is a sectional elevation of card teeth surrounding the pneumatic tube.
Fig. 3 is a plan of strips having the steel staples or card teeth upon separate
strips or foundations mounted upon further strip or backing.
Fig. 3 is a section showing arrangement of card strips when applied to wheels
of vehicles.
Fig. 4 is an elevation in section of strips with graduated card teeth.
Figs. 5, 6 and 7 show details of different forms or shapes of spring staples or
card teeth upon their strips or foundations before being placed upon the pneumatic
tube.
A are the central card teeth or spring steel staples preferably hardened, tempered,
and tinned, B B are the outside teeth which I make of shorter length than the
central teeth; one leg of each outside tooth is made shorter than its other and set
so as to graduate the height of the card from the centre to the sides. They are
preferably set upon separate thin strips or foundations C and then mounted on one
wide strip C (see Figs. 3 and 4). D is the outer cover which may be of the
Dunlop form or any
other suitable form of outer cover, E is the
inflating or pneumatic tube, the card teeth may be of any
suitable
strength, length, closeness, or shape, and may consist of any number
of strips and may either cover the top part of the pneumatic tube (sce
Fig. 1), or surround it as shown at Fig. 2. F are teeth having a double bend for
increasing their elasticity.
The ends of the card teeth, pins, or staples, are preferably blunt or rounded.
When the shield is used in Fig. 2 the strips Care preferably put on in rings or
short lengths and are wide enough to surround the pneumatic tube E and are
mounted upon a flexible back C the length of the circumference of the pneumatic
tube upon the tyre, the card teeth as used in Fig. 2 are shorter and do not require
graduating.
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. Tyres for cycles and the like vehicles having a resilient shield or protector
from puncture, consisting of a strip or strips of (preferably) hardened and tempered
steel card teeth, pins, or staples upon suitable foundations between the pneumatic
tube or bed and the outer cover, for the purposes described.
2. Central strips of card teeth A having shorter side strips B, preferably set
on separate foundations C, then mounted on a back C, the card teeth being of any
suitable shape to give the required resiliency, and to shield the tube from puncture,
substantially as shown and described.

page_text: 3. Tempered steel card teeth A set upon a series of ring strips C then mounted
on a second strip C', the circumference of and surrounding the pneumatic tube E
substantially as, and for the purposes shown and described.
4. In pneumatic tyres forming graduated cards from the centre to the side and
so retaining the proper shape of tyre by making the teeth of the outer strips of
cards with one leg or pin shorter than the other as and for the purposes shown and
described.
