Improvements in or relating to Pneumatic Tyres.
We THOMAS ROWLEY, of Corporation Street, Consulting India Rubber Expert,
and ROBERT WILD, of Exeter Street, Ardwick, Manager, both in Manchester,
in the County of Lancaster, do hereby declare the nature of this invention to be as
follows:-
This invention relates to a means for securing a cover or envelope for the air
tube in a pneumatic tyre so as to be readily attached and detached to any form of
rim without the aid of wires or other especial appliance or device.
In the accompanying drawing
Fig. 1 shows a section of a rim with cover constructed according to this invention
and enclosing an air tube:
Fig. 2 is a side view showing a part of said cover partly opened, with an air
tube partially released therefrom.
In this invention we construct a cover of india rubber and canvas as a in the
ordinary manner, but with the circumferential edges b and b¹ of stout inextensible
cloth or canvas formed so as to lap one edge over the other on the inner side of
the cover within the hollow portion of the metallic rim c, and secured around the
air tube by studs or buttons d that are attached at intervals to one of said flaps
and passed through corresponding eyelets or equivalents in the adjoining flap.
In applying our invention, an air tube as e is enclosed in a cover as herein before
described and secured therein by the edges band b being fastened together by
means of the studs or buttons d. Said cover with tube is then placed within or on
the rim c, or other preferred form of rim, through which the valve is passed and
secured in the usual manner. The cover a is by these means securely attached to
the rim of the wheel.
For the purpose of inspecting or repairing the air tube the cover may be opened
at any part by removing one or more of the studs d from the eyelets d'.
A circumferential strip or flap may be placed over the heads of the studs to
protect the air tube from injury.

page_text: Improvements in or relating to Pneumatic Tyres.
We, THOMAS ROWLEY of Corporation Street, Consulting India Rubber Expert,
and ROBERT WILD, of Exeter Street, Ardwick, Manager, both in Manchester, in
the County of Lancaster, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described aud
ascertained in and by the following statement:-
This invention relates to means for securing a cover or envelope for the air tube
of a pneumatic tyre. The object of this our invention is to enable the said cover
or envelope to be, more easily and readily attached to, and detached from any
preferred form of rim than is possible when wires or other special appliances
or devices such as wires in or thickened edges of the cover or envelope are
employed.
We attain this object by the means hereinafter described and as shown in the
accompanying sheet of drawings in which
Fig. 1 represents a portion of the cover as seen when detached from the rim and
opened.
Fig. 2 shows the same portion of the cover enclosing an air tube and inflated as
it would be when in place on the rim.
Figs. 3 and 4 represent the aforesaid cover with air tube when placed on or
within the rim which may be either of metal or wood, but without reference to
the precise form of rims shown which may be of other preferred design or
construction.
Fig. 5 shows a transverse section of the aforesaid cover with the shanks of the
studs that are employed for fastening the cover embedded therein during the
process of manufacture:
Fig. 6 is a transverse section of the same cover, the air tube being protected
from injury by friction by means of a flap.
Figs. 7, 8, and 9 are illustrations of equivalent devices that may be employed
for connecting the circumferential edges of the cover, Fig. 7 representing an
ordinary form of hook and eye as used by dressmakers, Fig. 8 a hole with a slot
formed in a tab 62 for fastening to the stud or button d, aud Fig. 9 a lever
fastening similar to the lever fastenings employed for gloves.
In the several views shown on the drawing similar letters refer to similar parts.
In this invention we construct a cover of india rubber and canvas as a in the
ordinary manner, with the circumferential edges band 6 of stout cloth or canvas,
and said edges formed so as to lap one edge over the other on the inner side of
the cover within the hollow portion of a metallic or a wooden rim as c.
The cover a is secured around the air tube e by connecting the edges b and b
by means of studs or buttons as d or like equivalents such as are shown in Figs. 7,
8, and 9, said studs or equivalents being attached at intervals to one of the
aforesaid edges, and passed through corresponding eyelets or equivalents d' that
are formed on or attached to the adjoining edge.
In applying our invention, an air tube as e is enclosed in the cover as herein-
before described and secured therein by the edges & and b' being fastened together
by means of the studs or buttons d, or the like. Said cover with tube is placed
within or on a rim as c or other preferred form of rim through which the valve is
passed and secured in the usual manner and the tyre is then inflated.
For the purpose of inspecting or repairing the air tube, the cover may be opened
at any part by removing one or more of the studs from the eyelets d' or
disconnecting any like fastener such as herein before named.

page_text: A circumferential strip or flap as a see Fig. 6 may be placed over the
projecting portions of the studs or fasteners to protect the air tube from injury.
We do not confine ourselves to the precise form of stud, button, or like fastening
shown on the drawing. We are aware that studs and the like have been
employed prior to the date of this invention, but in all cases in combination with
certain formations or devices on or in the rim: also we are aware that the
circumferential edges of covers for air tubes in pneumatic tyres have been
connected by means of lacing with cords passed through eyelet holes, but in these
cases when it is required to obtain access to the air tube it is necessary to withdraw
the lace and to unfasten the whole or a considerable portion of the whole length of
the cover: but
Having now particularly described and ascertained the nature of this our said.
invention and in what manner the same is to be performed, we declare that what.
we claim is :-
1st. In pneumatic tyres for wheels, or tyres that are constructed of an air tube
containing air under pressure and enclosed within an envelope or cover, the use of
studs or buttons as represented in Figs. 1 and 2 that are attached to or formed on
one of the circumferential edges of said cover for insertion in corresponding holes
formed in the adjacent circumferential edge of cover which fastenings when the
tyre is inflated bed within the hollow of the rim in the manner and for the purpose
substantially as herein before described.
2nd. In pneumatic tyres for wheels that are constructed of an air tube
containing air under pressure and enclosed within an envelope or cover, the use of
an equivalent to studs or buttons such as the fastenings represented in Figs. 7, 8,
and 9, attached to or formed on one of the circumferential edges of said cover for
connection with corresponding fastenings that are attached to or formed on or in
the adjacent circumferential edge of cover which fastenings when the tyre is inflated..
bed within the hollow of the rim in the manner and for the purpose substantially as.
hereinbefore described.
3rd. The construction of pneumatic tyres consisting of air tube, cover and.
fastenings combined with the rim substantially as described and illustrated.
