Complete Specification Left, 19th Nov., 1896-Accepted, 27th Feb., 1897
JOHN EDWARD ROGERS of 85 Sycamore Road Smethwick near Birmingham
Machinist do hereby declare the nature of this invention to be as follows:-
For the purpose of describing my invention we will suppose that it is to be
applied to a bicycle wheel, or wheels I should take a cover of rubber or other
suitable material similar to the outer rubber cover at present used in combination
with the well known pneumatic tyre with suitable attachments for fixing it to the
rim of the bicycle wheel.
1 should then take a strip of steel or other metal having sufficient spring in it,
of the required length width and thickness coil it up as required place it inside the
before mentioned cover, when the spring would adjust itself to the inside diameter
of the cover which cover with the spring inside would then be fixed to the rim of
the wheel making the tyre complete according to my invention.
I do not bind myself to use only a flat section of steel, or metal, but may curve
it or vary the section as I may think fit adapting the outer cover to suit the desired
variations.
The length of the strip of spring steel or metal would be so arranged to give the
required number of coils inside the outer cover.
Dated this 30th day of March 1896.
I JOHN EDWARD ROGERS of 85 Sycamore Road Smethwick near Birmingham
Machinist 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 :-
Fig. 1 of the accompanying drawing shews the section of a tyre for heavy work
constructed according to my invention.
The design and method of attaching tyre to rim may be varied to suit the class
of wheel required.
(A) is the outer flexible cover made of rubber or other suitable material.
(B) is a solid rubber ring fixed on the rim (C).
(D) and (D) are rings for fixing flexible cover (A) on to rim (C) by means of
bolts (E) arranged at equal distances in the circumference of the tyre.
(F) is a strip of metal preferably steel of sufficient length and strength to give
the required number of coils on the inside circumference of the flexible cover (A)
according to the elasticity required in the tyre; that is to say, I take a strip of

page_text: steel of a desirable section as shewn in drawing marked (F) which shews four
layers of the section of strip steel required the four layers of steel are made
preferably, by one length of steel which when coiled up would in section shew the
four thicknesses of steel formed by the coiled strip when placed inside the flexible
cover (A).
If for any purpose it is desirable I may use inside the flexible cover (A) more
than one strip of steel and with varying strengths.
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) The outer flexible cover (A) in combination with a strip of metal (F) coiled
in layers in the inner circumference of the flexible cover (A) forming a tyre for
attaching to the rim of a wheel substantially as shewn and described.
Dated this 17th day of November 1896.
JOHN EDWARD ROGERS.
