PROVISIONAL SPECIFICATION.
Improvements in or appertaining to Cushion Tyres, especially
applicable to the Wheels of Bicycles, Tricycles, or the like.
1, WILLIAM TIMBERLAKE, of 35 Nevill Street, Southport in the County of
Lancaster, Bicycle & Tricycle Manufacturer, do hereby declare the nature of this
invention to be as follows:-
This invention relates to cushion tyres intended chiefly for the wheels of bicycles,
tricycles and other like velocipedes, its principal object being the affording of
facilities whereby such tyres may be fitted on to the hollow rim of an ordinary solid
tyre wheel.
In carrying the invention into effect, I construct a hollow tyre having a D-shaped
cross section, the hole in the interior being either round, elliptical, D-shaped or of
other suitable form in cross section, and the tyre being formed in a piece or in
lengthis cemented together.
At the angles of the tyre, I provide flaps of canvas, or other suitable material by
means of which the tyre may be attached to the rim, the flaps being laced together
or otherwise connected to each other or to the rim.
Round the periphery of the hollow rim, I place a thin flat band of steel, which
forms a foundation for the flat face of the cushion tyre, and may be attached to
the rim in any convenient manner, as for example, by being clipped over the edges
of the rim.
In applying my improved tyre to specially constructed wheels, I form the rim of
the wheel hollow and of a D-shaped cross section, the flat side of the D forming
the foundation for the tyre.
The tyre may be cemented on to the separate foundation plate or on to the flat
side of the specially constructed rim in the ordinary manner.

COMPLETE SPECIFICATION.
Improvements in or appertaining to Cushion Tyres, especially
applicable to the Wheels of Bicycles, Tricycles, or the like.
1. WILLIAM TIMBERLAKE, of 35, Nevill Street, Southport, in the County of
Lancaster, Bicycle and Tricycle 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 :-
This invention relates to cushion or like tyres intended chiefly for the wheels of
bicycles, tricycles and other like velocipedes, its principal object being the
affording of facilities whereby such tyres may be fitted on to the rims of wheels.
Hitherto cushion tyres have often been cut and mutilated by the sharp edges of
the rim, and the life of the tyre is thereby greatly reduced; by the peculiar
formation of my rim however this defect is entirely avoided.
In carrying the invention into effect, I construct a tyre having an essentially
D-shaped cross section, with or without a hole in the interior, the said hole being
either round, elliptical, D-shaped or of other suitable form in cross section, and the
tyre being formed in a piece or in lengths cemented together, thus enabling me to
have a compressed tyre instead of a stretched one.
At the angles of the tyre, I provide flaps C of canvas, or other suitable material

page_text: by means of which the tyre may betattached to the rim, the flaps C being laced
together or otherwise connected to each other or to the rim.
In applying my tyre to the ordinary rims of solid-tyre wheels, I place round the
periphery of the rim a thin flat band of steel, which forms a foundation for the flat
face of the cushion tyre, and may be attached to the rim in any convenient manner,
as for example, by being clipped over the edges of the rim.
In applying my improved tyresto, specially, constructed, wheels, I form. the rim of
the wheel hollow or solid. and ofya D-shaped cross section, the flat side of the D
forming the foundation for the tyre.
Referring to the drawings:-
:-
Figure 1 shows a tyre A having canvas face B preferably made in the tyre and
canvas flaps C for attaching them to the rim or to each other by lacing wire or
other-means.
D is the rim, and E an iron or steel band clipped and shrunk on
.the rim.
In the other figures like letters refer to like parts.
..Figure 2 shows a slight modification in which instead of wiring or lacing the
canvas round the rim, two wires F F, passing through holes in the flaps C of
the tyre over the canvas, compress the latter against the band E. This and
the preceding figure shew the tyre applied to an ordinary rim.
Figures 3, 4 and 5 show a variation of Figure 2, where the rim is specially
manufactured to suit the tyre instead of as in Figure 2; where the invention is
applied to an old rim.
Figures 6 and 7 a simpler type in which the tyre is stretched on to the rim, and
.fastened on by cement or in other suitable manner.
Figure 8 shews a variation of Figure 1 where the rim is specially manufactured
to suit the tyre instead of in Figure I where the invention is applied to an
old.rim..
Figure 9 is an enlarged view of part of Figure 5.
་
In all the above figures (except Figures 6-and-7-) the tyre is compressed on-the
rim, all parts of the tyre being thus in compression instead of in tension. This plan
possesses advantages over the old way of stretching the tyre on, as none of the.
cushion properties are destroyed; the tyre is not liable to come off, and it is not, so
easily cut, or if cut would close up again.
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 combination with a concave rim of a flat or approximately flat-outer
plate and a cushion .tyre with similar flat,side fixed, thereon.
2. The attachment of cushion tyres to flat or nearly flat surfaced.rims by means
of canvas and lacing, or wiring, substantially as described.
