PROVISIONAL SPECIFICATION.
Improved Non-slipping Band or Appliance for the Pneumatic Tyres
of Bicycles.
I, ALEXANDER MELVILLE CLARK, of the Firm of A. M. & Wm. Clark, of 53,
Chancery Lane, in the County of Middlesex, Fellow of the Chartered Institute
of Patent Agents, do hereby declare the nature of this invention (a communica-
tion to me by Deutsche Nähmaschinen-Fabrik von Jos. Wertheim, of Frankfort-
on-the-Main, in the Empire of Germany) to be as follows:-
This invention relates to an improved non-slipping band or appliance for the
pneumatic tyres of bicycles, which may be easily applied or removed as the
state of the roads may necessitate during a journey or otherwise, which is
eminently adapted to fit snugly upon the jacket of the tyre, does not detract
materially from the elasticity of the pneumatic tyre but is free to yield under
compression whilst it affords the required protection against slipping, and is
generally efficient to an extent not possessed by other non-slipping appliances
heretofore devised. It consists essentially of small plates with V-points punched
up from them so as to come in contact with the ground, the V-points presenting
their inclined sides towards the forward direction so as not to interfere with the
action of the brake, and the plates being flexibly connected by links to each
other and to lateral chains or being separately connected by links and springs
to hooks fixed to the sides of the tyre cover or being attached to rubber strips
cemented to the sides of the jacket so as to adapt themselves to the form of and
closely embrace the tyre when fully inflated and admit of easy removal either
entirely or by turning back towards or over the back of the rim of the wheel,
as the case may be.
In the accompanying drawings forming part of this specification, Figures 1, 2,
and 3 are an edge view, cross section, and side view of a tyre B with a non-
slipping band applied consisting of plates D with V-points & punched up there-
from the plates being connected by diagonal links a to each other and to
non-extensible chains A whose ends are connected by hooks e, c the chains being
of such length that when the tyre is inflated they will occupy the position shewn
the links fitting snugly around the tyre and the plates becoming embedded suffi-
ciently in the jacket A so as to prevent all shifting of the band upon the tyre
whilst the projecting V-points are free to yield to a certain extent under pres-
sure upon hard ground whilst fulfilling their function of preventing slip.
Figures 4, 5, 6, and 8 are views shewing the pointed plates D rivetted to rubber
flaps E united at their outer edges to the sides of the tyre jacket B so that when
required for use the flaps E may be made to snugly envelop the tread of the tyre
by their adjacent edges being laced together by laces or wires F passed around
lacing hooks or equivalent fastenings f as shewn in those figures.
When the non-slipping band is not required, it is only necessary to unfasten
the lace or other fastening whereupon the flaps E will spring back by their
inherent elasticity and occupy the rolled-back position alongside the wheel rim,

Improved Non-slipping Band or Appliance for the Pneumatic Tyres
of Bicycles.
I, ALEXANDER MELVILLE CLARK, of the Firm of A. M. & Wm. Clark, of 53,
Chancery Lane, in the County of Middlesex; Fellow of the Chartered Institute
of Patent Agents, do hereby declare the nature of this invention (a communica-
tion to me by Deutsche Nähmaschinen-Fabrik von Jos. Wertheim, of Frankfort-
on-the-Main in the Empire of Germany) 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 an improved non-slipping band or appliance to be
affixed to the pneumatic tyres of bicycles. It may be easily applied or removed
as the state of the roads may necessitate during a journey or otherwise, is emin-
nently adapted to fit snugly upon the jacket of the tyre, does not detract materially
from the elasticity of the pneumatic tyre but is free to yield under compression
whilst it affords the required protection against slipping, and is generally efficient
to an extent not possessed by other non-slipping appliances heretofore devised.
It consists essentially of small plates with V-points punched up from them so as,
when applied to the tyre, to project therefrom in such manner as to come in
contact with the ground, the V-points presenting their inclined surfaces in such
direction as not to interfere with the action of the brake. The plates are flexibly
connected by links to each other and to lateral chains or are separately connected
by links and springs to hooks fixed to the sides of the tyre cover or are attached
to rubber strips cemented to the sides of the jacket so as to adapt themselves/to
the form of and closely embrace the tyre when fully inflated and admit of easy
removal either entirely or by turning back towards or over the back of the rim
of the wheel, as the case may be.

In the drawings accompanying the Provisional Specification Figures 12 and 3
are an edge view, cross section, and side view of a tyre B having applied thereto
non-slipping band consisting of plates D with V-points d punched
up therefrom, the plates being connected by diagonal links a to each other and to
non-extensible chains A whose ends are connected by hooks e c the chains being
of such length that when the tyre is inflated they will occupy the position shewn,
the links fitting snugly around the tyre and the plates becoming embedded suffi-

page_text: ciently in the jacket A so as to prevent all shifting of, the band upon the tyre
whilst the projecting V-points are free to yield to a certain extent under pres-
sure upon hard ground whilst fulfilling their function of preventing slip.
Figures 456 and 8 are views shewing the pointed plates D rivetted to rubber
flaps E united at their outer edges to the sides of the tyre jacket B so that when
required for use the flaps E may be made to snugly envelop the tread of the tyre
by their adjacent edges being laced together by laces or wires F passed
around lacing hooks or equivalent fastenings f as shewn in those figures.
When the non-slipping band is not required, it is only necessary to unfasten
the lace or other fastening whereupon the flaps E will spring back by their
inherent elasticity and occupy the rolled-back position alongside the wheel rim
as shewn in Figure 8, leaving the smooth tread of the tyre exposed to contact
with the ground.
Figure 7 is a section through one of the V-pointed plates D.
Figures 9 and 10 are cross section and face view shewing V-pointed plates
connected by oblique links to hooks fixed alternately at opposite sides of the tyre
and Figures 11 and 12 are similar views shewing the V-pointed plates not con-
nected in the form of a continuous band or chain but each separately attached
by means of chains formed partly of plain and partly of spring links these chains
being permanently attached to the tyre jacket at one side and detachably con-
nected thereto by spring hooks at the other side so that when the non-slipping
plates are not required for use they may be removed from the tread and be simi-
larly fastened after being passed inwards over the back of the wheel rim
shewn in Figure 11.
as
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
1. A non-slipping appliance or band for pneumatic tyres, consisting essen-
tially of small plates having projections adapted to come in contact with the
ground, the plates being connected by links to form an endless band or chain
adapted to embrace the tyre as specified.
2. A non-slipping appliance or band for pneumatic tyres, consisting essen-
tially of small plates having projections adapted to come in contact with the
ground, the plates being separately attached to rubber flaps united to the sides
of the tyre jacket and adapted to be laced or otherwise secured in position to
envelop the tyre or to turn back as described when the non-slipping appliance
is not required for use, substantially as specified.
3. A non-slipping appliance or band for pneumatic tyres, consisting essen-
tially of small plates having projections adapted to come in contact with the
ground, the plates being separately attached to the tyre by links and detachable
spring fastenings admitting of being removed from the tyre and fastened around
the back of the rim when the non-slipping appliances are not required for use,
substantially as specified.
