page_text: JOHN WILCOCK Merchant and Manufacturer, 77 Cecil Street, Manchester and
ADAM BRADLEY Salesman 20 St. Thomas Street North Oldham do hereby
declare the nature of this invention to be as follows:-
This invention is designed to provide a cleaning apparatus adjustable to all
kinds of bicycles or cycles driven by a chain running over suitable cog or toothed
wheels.
It consists essentially of a small brush to which is attached an arm or bracket
made of metal or other suitable material at the end of which arm or bracket is
bored a hole, or if wire is used a ring is formed, large enough to pass over the
threaded talepiece of the drawlink which carries the nut for tightening the driving
chain. The brush is made of bristle or of such other fibre as is used in ordinary
brushmaking and the bristles or fibres are cut a suitable length to avoid friction in
the working and also to pierce between the links or blocks of which the chain is
constructed. The face of the brush may be shaped concave so as to cover more of
the chain and the wheel.
The brush is adjusted by passing the arm or bracket over the threaded tailpiece
up to the nut or nuts which regulate the tension of the driving chain and is held in
position by a similar nut screwed against the bracket on the tailpiece. The brush
thereby rests upon the outside of the chain and the chainwheel and is held in firm
position while the chain revolves. The brush may also be attached by means of
an ordinary clip or screw to one of the back stays or rear fork-end immediately
above the chain and gear wheel but resting upon them.
In this position the brush clears away all the dust and dirt which the chain
and gear wheels may gather whilst the machine is in motion over wet and dirty
roads.
This invention dispenses with the ordinary gear case generally used for covering
the chain and gear wheels and by its application the chain is kept clear of the grit
and dirt which impede the speed of the machine.
To put the apparatus out of gear or use, the nuts on the chain-regulator or
tailpiece are unscrewed far enough to draw the brush from touching the chain, or
in the case of the clip, it is placed higher up the stay or rear fork.
If it is desired a double brush or two of the brushes described above can be
fixed on the backfork or stays or both by means of a clip or screw one brush
resting on the outer and the other against the inner surface of the chain.

page_text: We, JOHN WILCOCK Merchant and Manufacturer of 77 Cecil Street
Manchester and ADAM BRADLEY Salesman of 20 St. Thomas Street North
Oldham 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 is designed to provide a cleaning apparatus adjustable to all
kinds of bicycles or cycles driven by a chain running over suitable cog or toothed
wheels.
The invention will be best understood by reference to the accompanying
drawings:-
Figure 1 Elevation of apparatus fixed in position at the fork-end of the tubes
under the saddle of the bicycle.
Figure 2: End view of the brush and bracket (the tightening nut being shown
in dotted lines).
Figure 3: Sectional elevation of brush and bracket.
Like letters indicate like parts throughout the drawings.
The brush A is constructed with ordinary bristle, fibre or other suitable
amaterial (a) inserted in a stock made of wood or other substance. The bristle (a)
is left sufficiently long to offer no more resistance than that of its own strength
when bent.
The bracket or arm B, Fig. 1, is a thin metal plate fastened to the stock A of
the brush by the ordinary methods and has a slot (b) cut in the centre. The
bracket or arm may be made of wire shaped to the outline of the slot and similarly
fastened to the stock A. The slot (6) is of sufficient length to allow of the bracket
being bent at right angles B¹ at varying distances to suit the relative positions of
the draw-link or tightening screw C and the chain D. The bracket B is placed
on the tail-piece of the draw-link C and is screwed firmly against the tightening
nut by means of an extra nut C. The brush thus resting on the links of the chain D,
and being fixed at the back of the machine, sweeps all the dust and dirt accumulated
by the chain away from the machine.
Instead of being fixed on the tailpiece C the bracket or arm B may be attached"
-to the back stay-tube E by means of an ordinary spring clip or a screw, and the
surface of the brush will then rest upon the chain and wheel at the point D¹. In
this position the dust or dirt will be swept away from the machine in the same
manner as when fixed on the tail-piece of the draw-link C.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
A cleaning apparatus adjustable to bicycles or cycles driven by the block or
roller chain, and in the form of a brush fixed as herein described by which dust
-and dirt is swept away from the machine while in motion.
Dated this Twentieth day of February 1897.
