Improvements in Wheels for Velocipedes.
I GEORGE COUSINS of Birchington in the County of Kent, Velocipede
Manufacturer do hereby declare the nature of this invention to be as follows:-
The object of my invention is to provide a ready and effective means for securing
rubber tyres to the rims of velocipedes and for this purpose I form my rubber tyre
with the lower surface flat or concave and having attached or vulcanized thereto a
strip of canvass or other suitable material in such a manner that the centre portion
thereof shall be loose and capable of being drawn downwards by the tightening of a
wire, cord or other fastener, i.e., the sides of the canvass are secured to the rubber
whilst a small portion in the centre is free therefrom and assumes a "baggy
shape.
"
"
Instead of the ordinary rim I employ one with a convex surface having in its
centre a depression or concavity in which may lie the "baggy
portion of the
canvass before described and the wire, cord or other fastener.
To secure the tyre which may be solid or " cushioned I pass a wire, cord, chain
or other suitable fastener through the "baggy or loose portion of the canvass the
ends projecting through holes therein; these ends are then passed through holes or
tubes provided in the rim and after the tyre has been sprung on are tightened by
means of nuts, screws or in any desired manner.
Dated this 2nd day of January 1891.

Improvements in Wheels for Velocipedes.
I, GEORGE COUSINS, of Birchington, in the County of Kent, Velocipede
Manufacturer, 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 :-
The object of my invention is to provide a ready and effective means for securing
rubber tires to the rims of velocipedes, and for this purpose I form my rubber tire
with the lower surface flat or concave and having attached or vulcanized thereto a
strip of canvas or other suitable material such as woven metal, in such a manner
that the centre portion thereof shall be loose and capable of being drawn down-
wards by the tightening of a wire, cord or other fastener, i.e., the sides of the canvas
are secured to the rubber whilst a small portion in the centre is free therefrom and
assumes a "baggy" shape.
Instead of the ordinary rim I employ one with a convex surface having in its
centre a depression or concavity in which may lie the "baggy" portion of the
canvas before described and the wire, cord or other fastener.
To secure the tire, which may be solid or " cushioned "I pass a wire, cord,

through holes or tubes provided in the rim and after the tire has been "sprung
on are tightened by means of nuts, screws or in any desired manner.
"
"
The rubber tire may be of any suitable section and either solid or of the
cushion type and one object of my invention is to prevent the evil effects of
"spreading"

page_text: Referring to the accompanying sheet of drawings and to the figures and letters
of reference thereon,
Figure 1 is a transverse section through tire, canvas and rim showing the
position of the canvas when stretched by the tightening of the cord, in which A
is the tire, the dotted circle B indicating the orifice of a cushion tire, C is the
canvas to which the rubber is vulcanized or otherwise secured, D the space left
in the centre free from the canvas, E is the "baggy or loose portion and F
the wire, cord or equivalent running through the same to tighten and secure it.
G is the rim formed convexly and having a bent down portion H in the centre
through the bottom of which the spoke J is inserted and secured.
"
Figure 2 shows an alternative method of attaching the canvas to the rubber
whereby the loop or "bag is formed of a separate piece of canvas C₁ stitched
or fastened to the main portion C which is vulcanized or secured to the rubber
throughout its whole surface.
Figures 3, 4 and 5 are different forms of rim which may be conveniently
employed.
The wire or cord may be tightened by several well known devices or methods
and I prefer one described in a Provisional Specification filed by John Kemp
Starley No. 4860 dated Novb. 7, 1881.
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. The method of securing the tires of velocipedes to their rims substantially as
herein described with reference to Figure 1 of the accompanying drawings.
2. The alternative method of forming the loop or
bag
illustrated by Figure 2 of the accompanying drawing.
E substantially as
3. The specially formed rims as shown in Figures 1, 3, 4 and 5 of the accom-
panying drawings or any mere modification of the same.
