Improvements in or relating to Pneumatic Tyres.
I, JOHN ALMOND 621 Hyde Road Gorton Manchester India Rubber Artisan
do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in the construction of Pneumatic Tyres for
cycles and other like vehicles. The chief object of my invention is to bind and
protect the edges of Pneumatic Tyres, with a metallic binder as a protector, my
reasons for binding the edges of Pneumatic Tyres, with a metallic protector being to
avoid the usual destruction which takes place in case of puncture to Pneumatic Tyres
containing metal wires folded into the edges of the canvas, which has to be sprung
over the edges of the rim, with an implement used similar to those mentioned for
the purpose in Welch's Patent 14563 of 1890, or the nearest implement to the
operators hand in wrenching the edges of these Pneumatic Tyres covers over
the edges of the rim, the edges of the canvas being often cut away or frayed by the
Baid tools used rendering the Tyre useless where it is cut. In accordance with my
invention I build a Pneumatic Tyre up of linen canvas, and Rubber or cotton duck
and Rubber. I then make the said metallic binder as a protector, which consists of
a plat strip, or band of Steel, Brass, Bronze or any sufficient inelastic material to
answer the purpose, the raw edges of tho said strip or band, I turn close inwards the
reinaining edges being blunt to prevent cutting of the lower edges of Tyre. After
this is done, I bond the same into U form to receive the edges of the canvas and
Rubber Tyre. I then place the edges of the canvas and Rubber Tyro into the
U shaped protector, which is in ring form, thoroughly encircling the edges of the
canvas and Rubber Tyre, the edges of the canvas and Rubber Tyre being embedded
continuously into the U shaped protector. I then pinch the edges of the protector
tightly on to the edges of the canvas in suitable form, I then spring the edges of the
Tyre over the edges of the wheel rim and Rubber air containing chamber, fitted with
valve, to which I attach air pump and fill with air.
The metallic protector I may inake endless or otherwise in applying the same to
the edges of Pneumatic Tyres, & it may in some instances be necessary to vary the
details of construction.

I, JOHN ALMOND late of 621 Hyde Road; Gorton, Manchester, and now of
23 Moreton Avenue, Burnage Lane, Levenshulme, Manchester, India Rubber Artisan,
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:

page_text: My invention relates to pneumatic tyres for cycle and other vehicle wheels, and
more especially to those tyres which embody a detachable cover, and my invention
consists essentially in applying to the edges of the said cover a metal binding similar
in size and cross-section to the channelled ribs of what is known as a Fox's Paragon
Frame for Umbrellas. Such binding is made in a length equal to, or slightly greater
than, the circumference of the cover edges, and is fixed on to such edges by rolling,
pinching, moulding, pressing or in any other suitable way.
Whilst chiefly applicable to a detachable cover the improved edging is applicable
for the utilisation of old and discarded hose pipe' and like made up pipes, which I
may out longitudinally upon the inner circumference, and apply iny improved edging
to the respective edges thereof, and use as covers for pneumatio tyres,
And in order that my said invention may be more readily understood and carried
into practical effect, I have hereunto annexed a sheet of drawings and will now
proceed to describe the same with the figures and letters of reference marked
thereon.
Fig. 1 is a transverse section of a detachable cover with my invention applied
thereto. Fig. 2 is a transverse section of a tyre and shewing the application of my
improved cover thereto.
Figs. 3 to 6 illustrates my invention and modifications thereof in detail, and on an
enlarged scale.
As before stated my invention consists in providing the respective edges of the
detachable cover (A) of a pneumatic tyre with a channel shaped metal edging or
binding (B) which is, by preference, of shallow formation or cross-section and when
firmly clamped or nipped on the cover has the appearance of a solid wire-like edging.
For this purpose the metal binding may be of somi-circular cross-section previous to
being clamped on to the cover as shewn in Fig. 5. To cause it (the edging) to lic
flat upon the rim I give the edging a dished or tapered set in the process of its
manufacture, or when pinching or fixing it on the edging as shewn in Figs. 1 and 2.
The edging is, by preference, made of steel and enamelled or tinned, or otherwise
treated to resist corrosion. It may be of aluminium or other suitable and
non-extensible material, metallic or non-metallic.
As in all other detachable covers the edging (B) is of less circumference than the
air tubo when inflated and sits saddle fashion upon the air-tube. The ends of the
edging are joined in any suitable way, and either overlap or abut, and are connected
by brazing.
In attaching and detaching my improved cover the edges are sprung over the
edges of the rim in like manner to what is known as the 'Welch' Cover, a lever like
device being used to raise or lever the edging, over the rim in detaching, and
stripping the cover from the rim. In this connection I would here observe that the
use of the lever does not fray or damage the cover, as in the case of the Welch'
cover, but tho metal edging forms a convenient surface or abutment for the tool,
and enables it to strip the cover from the rim in a much easier and quicker
manner.
To further ensure of the fixing of edging (B) I may thicken the extreme edges
of the cover lying within the edging and so form a suitable shoulder or body over
which to clamp the edging and ensure of its permanent attachment. To serve this
same purpose I may insert one edge or flap of thin india-rubber (C) and
allow the flap to lie between the said edging, and the air tube as shewn in
Fig. 6.
Lastly, the application of my improved edging effects a simplification in the
manufacture of the cover, since all cementing and folding of material is
avoided, and no. excess of material is required to provide for wires or embedded
rings.
Having thus particularly described and ascertained the nature of my said
and in what manner the same is. to be porformed I declare that what TA
