COMPLETE SPECIFICATION.
Improvements in Pneumatic Tyres for Cycles.
I, THOMAS FRANCIS DREW, of 18 Craven Road, in the County of London,
Boot Maker, 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 improvements in pneumatic tyres for cycles or other
vehicles, which consists of a cover to enclose an inflated tube constructed of canvas
with a longitudinal india rubber pad; and fixed to each edge of the canvas is a
strip of leather by means of eyelets and sewing cotton. The edges of the leather
strips are laced or otherwise fastened together enclosing the pneumatic tyre or
inflated tube.
And in order that my invention may be thoroughly understood, I now proceed to
describe the accompanying drawing thereof, reference being had to letters and
figures marked thereon.
Fig. 1, is a section of the cover, pneumatic tube and rim of wheel.
Fig. 2, is a view of the cover laced together on the pneumatic tube.
Parts of Fig. 2, is broken off for want of space.
This invention is constructed with a double thickness of canvas b with a
longitudinal strip of india rubber a fixed to the said canvas. To the sides of the
canvas b' is fixed a tongue b¹ of webbing as in Fig. 1, and on the edges I fix strips
of leather e by means of sewing the leather e to the canvas 6 with cotton and by
metallic eyelets g.
The cover is secured to a pneumatic tyre c by means of long or short laces d
passed through the eyelets g as in Fig. 2, and the whole forced on the rim f of a
wheel before the tyre is inflated to the full extent.
The leather and laces grip the rim of a wheel, when the pneumatic tyre is fully
inflated and thereby prevents the aforesaid invention from becoming detached or
either creeping or moving in the slightest degree.
Holes may be used in place of eyelets.

page_text: The object of my invention is to facilitate the mode of adjusting a tyre to the
rin of a cycle wheel.
I am aware that covers for tyres has been laced together through holes in the
ordinary material prior to my invention; but I am not aware that a double canvas
cover with an india rubber longitudinal pad and leather strips and a tongue has ever
been used together previous to my application for a Patent.
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. In: pneumatic tyres for cycles, the combination of the canvas & tongue b
india. rubber a leather strips e eyelets g (or holes) and laces d, for enclosing
pneumatic tyres, substantially as herein described and according to the accom-
panying drawing.
2. In pneumatic tyres for cycles, a cover for enclosing an inflated tube by means
of lacing in eyelets or holes two strips of leather together inside the rim of a
wheel, substantially as herein described and according to the accompanying
-drawing.
