Improved Means for Securing the Covers of Pneumatio Tyres.
I, HERBERT WALTER LOADS of Calvert Street, Norwich, Manufacturer, do hereby
declare the nature of this invention to be as follows:-
The cover of the tyre is divided longitudinally and two corresponding series of
eyelet holes or other suitable openings aro formed in the edges thereof, one series
in ench edge. The pneumatic tubo is then placed in the covor after which the two
edges of the latter are drawn together and socurely fastened by means of laces or
loops or their equivalents.
Improved Means for Securing the Covers of Pneumatic Tyres.
I, HERBERT WALTER LOADS of Calvert Street, Norwich, Manufacturer, do
hereby declare the nature of this invention and in what manner the same is to bo
performed, to be particularly described and ascertained in and by the following
statement:
The object of this invention is to afford a simple ready and effective means for
securing the covers of pneumatic tyres, and in order that my said invention may
be better understood and readily carried into offect, I will now with the aid of the
accompanying drawings, whereon similar letters of reference indicate corresponding
parts, proceed more particularly to describe and illustrate the same.
In the accompanying drawings Figure 1 is a plan and Figure 2 a detail view of
one method of carrying out my invention, Figures 3 and 4 shew transverse sections,
Figure 5 a plan, and Figures 6 and 7 detail views of a modification of such invention.
According to one method of carrying out my invention which is illustrated at
Figures 1 and 2 of the accompanying drawings, the lateral edges of the tyre cover a,
have two corresponding serics of oyelet holes b formed therein, one series in each
edge. The air tube is then placed in such cover which is sufficiently large to
completely envelop the same after which the lateral edges are drawn together and
securely fastened by laces c or their equivalents. When laces are employed they
are formed into a series of loops, as shown at Figures 1 and 2, which loops are
passed through each other and drawn together in a similar manner as when closing
a military legging, and when so secured the two edges of the tyre cover overlap

page_text: each other and form a seam which takes its seating on the centre of the wheel rim;
thus forming a sheath that effectually protects tho air tube from injury.
A modification of my invention is shewn at Figures 3, 4, 5, 6, and 7, of the
accompanying drawings. Such modification consists in dispensing with one serie
of eyolet holes and substituting thorofor spring clips d, or their equivalents; whic
are so fitted as to leave a broad margin a' on that side of the cover to which the
are attached. When the air tube e is enclosed in the tyre cover a, such margin a
forms an overlapping flap, that partially envelops the air tube e, thus affording
additional protection thereto, and more firmly securing the tyre cover thereon,
owing to the pressure of the air tube when inflated on such overlapping flap.
The spring clips or their equivalents may he placed either longitudinally, as
shown in full liues, or transversely, as shown in dotted lines, at Figure 5 of the
accompanying drawings; whilo preferably the lateral edge of the cover forming the
overlapping flap a' is tapered as shown in Figures 3, and 4, and also to an onlarged
scale in tho detail view Figure 7, to allow of the air tube fitting evenly the rein,
and so preventing its being chafed or pinched by the edge of the overlapping flap.
A rubber or other suitable outer tread is moulded or fitted on the tyre cover in the
ordinary manner.
One advantage of this improved method of securing the covers of pneumatic
tyres is that it requires no special form of rim, as the tyre may be readily fitted to
any form of rim used for pneumatic tyres and can be carried in the pocket when
not inflated.
A second advantage is that by fastening the two edges of the cover together so
as to form a seam which consequent upon the force of the pneumatic pressure, takes
a seating against and is securely held in position in the centre of the wheel rim f,
I entirely dispense with the use of wiros, canos, or other lateral fastenings round
the sides of such rim, which is a material benefit in as much as such lateral
fastenings froquently serve to rot the canvas and outer cover, and render the tyre
cumbersome.
A third advantage of my invention is that owing to the absence of any such
lateral fastenings the tyre can be much more readily removed when requisite, for
examination or repair and replaced.
I would here observe that the essential feature of my invention is, uniting the
two lateral edges of the cover of a pneumatic tyre so that they overlap each other,
and securing them by means of laces, spring clips, or other suitable equivalents, so
as to form a scam which when the tube is inflated takes a bearing against, and,
owing to the force of the pneumatic prossure, is securely held in position in the
centre of the wheel rim, all substantially as herein before described and shewn.
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. As a novol means of securing the cover of a pneumatio tyre, uniting the two
lateral edges thereof so that thoy overlap each other, and when fastened together,
either by laces, spring clips, or other suitable equivalonts, forin a seam, which,
when the air tubo is ouclosed in such cover and inflated, takes a bearing against,
and, owing to the force of the pneumatic prossure, is securely held in position in
the contro of the wheel rim, thus automatically securing the pneumatic tyre and
tyre cover in position, and dispensing with lateral fastenings of any description,
all substantially in the manner herein before described and shown.
2. A pueumatic tyre having a cover wherein two corresponding series of eyelet
holes are formed, one sories in each lateral edge, and which edges after the air tube
has been inserted therein are drawn together so that they overlap, and are secured
in that position by means of one or more lacos or their equivalents, all substantially
in the manner hereinbefore described and shown.
3. As a modification of my invention, a pneumatic tyre having a cover, one edge
whereof is provided with a series of eyelet holes, while the other edge is furnished

page_text: with spring clips or their equivalents, placed in the manner hereinbefore described
and shown, and which spring clips or their equivalents take into such eyelet holes,
the cover being of a sufficient width to form an overlapping flap, the edge whoreof
is preferably tapered, all substantially in the manner hereinbefore described and
shewn.
