Improvements in and relating to Tyres for the Wheels of
Velocipedes.
I FREDERICK LOUIS LANGE of 2 Norham Gardens, Oxford, in the County of
Oxon Gentleman, do hereby declare the nature of this invention to be as
follows:-
My invention relates to hollow tyres or to covers therefor, and it consists in
making on and in the tread or running surface, of the tyre or cover therefor, two
longitudinal ribs and a series of transverse grooves between the said ribs, the object
being to prevent both side slipping and driving slip.
In carrying my invention into practice I form on the tread or running surface of
the hollow tyre two circumferential grooves, parallel with each other and about
1 inch to 1 inches apart, according to the size of the tyre. Between these ribs
are formed a series of cross grooves or their equivalents about half an inch apart
and preferably formed in the thickness of the wall of the tyre."
To apply my invention to existing hollow tyres, I construct a cover with its
tread or running surface formed in the manner herein before described, and adapted
to be fixed over or round the hollow tyre by lacing, or by any other suitable and
equivalent device.
Dated this 20th day of November 1891.

COMPLETE SPECIFICATION.
Improvements in and relating to Tyres for the Wheels of
Velocipedes.
I FREDERICK LOUIS LANGE of 2 Norham Gardens, Oxford, in the County of
Oxon, Gentleman, 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 hollow tyres or to covers therefor, and it consists in
making on and in the tread or running surface of the tyre or cover therefor two
longitudinal ribs and a series of transverse grooves between the said ribs, the
object being to prevent both side slipping and driving slip.
I attain this end in the manner shown by the accompanying drawing in which
Figures 1 and 2 are views in transverse section of my improved cover made entirely
of rubber or analogous material, Figure 1 being a view through one of the transverse
grooves and Figure 2 a view between two of the said grooves. Figures 3 and 4
are similar views showing another method of constructing my improved cover, the
cover proper and the ribs being made of leather or analogous material, and the
tread part with the transverse grooves-of rubber or like material cemented or
otherwise fixed to the cover proper.
Throughout the several views similar parts are marked with like letters of
reference.
Referring to Figures 1 and 2. The cover A is made of rubber or any suitable
compound thereof, or of any analogous material, and it has on its outer face two
ribs a, a, running circumferentially around its entire periphery. Between these
two ribs the cover is preferably thickened as shown, and in it are formed a series

suitable distance apart.
Referring to Figures 3 and 4. The cover A is made of leather or other analogous
material and on its outer face are preferably formed the ribs a, a, by folding and
stitching as shown. Between these two ribs a band A' is fixed having a series of
transverse slots or grooves a¹, al, etc. according to the thickness of the said band.
This band A' is attached to the cover A by cementation, sewing or by any other
suitable means.
If this cover is used as the permanent cover of the tyre it is-adapted to be fixed
to the rim of the wheel by any of the well-known methods, but if it is intended to
be used as a supplemental cover adapted to be fitted over the existing cover of a
tyre it is fitted with eyelet holes, hooks, or their equivalents, or with any other
suitable devices, by which it can be fixed.round the tyre and rim of the wheel.
I am aware that the treads of tyres have already been made serrated or corrugated
and I do not therefore claim such broadly as my invention, but
"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 improvements in and relating to tyres as herein before described and
illustrated by the accoinpanying drawing.
2. A hollow tyre for the wheels of velocipedes having on its outer tread two
longitudinal ribs and a series of transverse grooves located between the said ribs,
as and for the purpose set forth.
3. A cover for the tyres of velocipedes having on its outer tread two longitudinal
ribs and a series of transverse grooves located between the said ribs, as and for
the purpose set forth.
