PROVISIONAL SPECIFICATION.
Improvements in and relating to Pneumatic Tyres. .
I, HENRY JELLEY, of 27 Malva Road, Wandsworth, in the County of Surrey,
Cycle Manufacturer, do hereby declare the nature of this invention to be as
follows:-
:-
My invention relates to a device for strengthening those covers of pneumatic
tyres fixed to wheel rims by means of wires located in pockets in the edges of the
cover and passing out through holes or openings therein, the object being to
prevent the said holes or openings becoming torn or enlarged by wear which
causes the cover at the part adjacent to the said holes or openings to expand when
inflated and so make the tyre at this point of an increased size and of an irregular
shape.
I carry my invention into practice by rivetting or otherwise fixing on the edge
of the cover over the holes or openings in the pocket therein a thin plate preferably
of metal and embracing both sides of the cover. When the ends of the wire cross
before passing out of the pocket the plate is made of a length equal to that
between the two holes or openings in the pocket through which the ends of the
wire pass, but if the ends of the wire cross at the point where they emerge from
the pocket in which case there is only one hole or opening-the plate is made of
any suitable length and it has a slot at or about its centre for the ends of the wire
to pass through, the two parts of the plate on each side of the said slot being set
off to allow the two ends of the wire to pass.
Dated this 14th day of June 1893.

COMPLETE SPECIFICATION.
Improvements in and relating to Pneumatic Tyres.
I, HENRY JELLEY, of 27 Malva Road, Wandsworth, in the County of Surrey,
Cycle Manufacturer, 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 a device for strengthening those covers of pneumatic
tyres which are adapted to be fixed to wheel rims by means of wires located in
pockets in their edges and passing out through holes or openings therein, and it
consists in strengthening or reinforcing the pockets round the said holes or
openings therein by means of metallic plates, the object being to prevent the said
holes or openings becoming torn or enlarged by wear which causes the cover at
the part adjacent to the said holes or openings to expand when inflated and so
make the tyre at this point of an increased size and of an irregular shape.
I attain this end in the manner illustrated by the accompanying drawing in
which :-
Figures 1 & 2 are broken views in side elevation of a cover of a pneumatic tyre
strengthened according to my invention, and
Figures 3 & 4 are views of other forms the strengthening plate may assume.
Pill

page_text: Throughout the views similar parts are marked with like letters of reference.
On to each edge of the cover A of the tyre over the holes or openings in the
pockets therein are fixed plates B preferably of metal, and so shaped as to embrace
both sides of the edge of the cover.
When the ends of the fixing wire X cross before passing out of the pocket
either two separate plates B, B, may be used as shown by Figure 1 or a single
plate B may be used as shown by Figure 3, the distance apart of the two
holes b, b, in the said plate being determined by the amount of lap given to the
ends of the wire X before they pass out of the pocket in the edge of the cover.
As a modification the plate B may be made of a length equal to that between the
two holes or openings in the pocket through which the ends of the wire pass in
which case simple notches or recesses are cut in the front edges of the said plate as
shown by Figure 4. If the ends of the wire X cross at the point where they
emerge from the pocket in the edge of the cover in which case there is only one
hole or opening the plate B is made of any suitable length and it has a single
hole or slot b for the ends of the wire to pass through, as shown by Figure 2, the
two ends of the plate on each side of the said hole or slot being set off to allow the
two ends of the wire to more readily and easily pass through the said hole or
opening.
The plates B are fixed to the edges of the tyre cover by rivetting or by any
other suitable means.
It will be seen that by the use of my invention the fraying, tearing and
enlarging of the holes in the pockets in the edges of the covers of pneumatic tyres
is entirely obviated.
I wish it to be particularly understood that I do not limit myself to the precise
details of construction herein before described and illustrated by the accompanying
drawing, but that I hold myself at liberty to make such changes and alterations as
fairly fall within the spirit and scope of my invention.
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 :-
1. The improvements in and relating to pneumatic tyres, substantially as herein-
before described and illustrated by the accompanying drawing.
2. In a pneumatic tyre the cover of which is adapted to be secured to the wheel
rim by means of wires or bands the ends of which pass out of the pockets in the
edges of the cover in which they are located, the use of plates such as B for
strengthening the covers at the holes or openings in the pockets through which the
ends of the wires pass, as set forth.
