An Improved Appliance for Maintaining the Driving Wheel and
Chain of a Bicycle Free from Dust.
I, WILLIAM PARKINSON, of Bridge Street, Warrington, in the County of Lan-
caster, Brush Manufacturer, do hereby declare the nature of this invention to be
as follows:-
This invention relates to an appliance for maintaining the driving wheel and
chain of a bicycle free from dust whilst cycling, by means of a brush.
It is well known that the chain of a bicycle when no gear case is used, carries
a great amount of dust and dirt, thus causing unnecessary friction and conse-
quently greater exertion on the part of the rider, in addition to reducing the
life of the chain and driving wheel.
My invention is designed with the object of providing a cheap and ready means
of overcoming in a great measure these defects and consists of an appliance con-
structed of three parts pivoted or otherwise fastened together for attachment to
the bottom stay of the framework of the bicycle and in close proximity to the
driving wheel.
I provide a clip or clamp of spring steel or other suitable material to one side
of which pivot or fasten a narrow strip of thin flat steel or other metal or
material and to the end of this strip is affixed by any suitable means that will
permit of its position being altered when worn down the brush stock of circular
segmental or other suitable shape as found desirable, so that the bristles are at
right angles to the strip.
When in use the clip is pressed over the bottom stay of the frame of the cycle
in a position to allow of the brush being in contact with the front of the driving
wheel so that when the back wheel of the bicycle is revolved it brushes away any
dust from the chain and driving wheel.

ascertained in and by the following statement:-
This invention relates to an appliance for maintaining the driving wheel and
chain of a bicycle free from dust whilst cycling, by means of a brush.
It is well known that the chain of a bicycle when no gear case is used, carries
a great amount of dust and dirt, thus causing unnecessary friction and conse-
quently greater exertion on the part of the rider, in addition to reducing the
life of the chain and driving wheel.
My invention is designed with the object of providing a cheap and ready means
of overcoming in a great measure these defects and consists of an appliance con-
structed of three parts comprising a brush, spring clip, and strip of flat steel
pivoted or otherwise fastened together for attachment to the bottom stay of the
framework of the bicycle and in close proximity to the driving wheel.
It will be fully described with reference to the accompanying drawings.
Fig. 1. Side elevation of the appliance (detached).
Fig. 2. Plan of same.
Fig. 3. Side elevation of driving wheel and chain of bicycle with appliance in
position.
Fig. 4. Front elevation of same.
A clip or clamp A of spring steel (or other suitable material) of a size to
clamp the tube or stay B of a cycle is fitted with a projecting strip or arm C of
thin flat steel (or other metal or material). To the end of the strip C, preferably
by means of a cup shaped enlargement c, is attached by a pin or screw d a small
brush of circular (or other suitable) form, preferably so as to be rotated about
the pin when required or otherwise to permit of its position being altered when
worn.
The brush D is made of bristles, fibre, wire or other suitable material.
When in use the clip A is pressed over the stay B of the frame of the cycle
in a position to allow of the brush D being in contact with the front of the
driving wheel E so that when the back wheel of the bicycle is revolved it brushes
away any dust from the chain F and driving wheel E
Having now particularly described and ascertained the nature of the said
.invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. An appliance for removing dust from the chains of cycles when in motion
comprising in its construction a small brush attached to a suitable spring or other
clip by which it can be affixed to the stay of the cycle, substantially as
described.
2. An appliance for removing dust from the chains of cycles having the several
parts constructed and arranged in combination, substantially as described and
shown.
