PROVISIONAL SPECIFICATION.
Improvements in Pedals for Velocipedes.
We, SAMUEL TWEEDALE, and JAMES CLEGG, Directors of the Firm of
S. Tweedale & Co., Limited, Hangh Cycle Works, Oldham Road, Rochdale in
the County of Lancaster, Cycle Manufacturers, do hereby declare the nature of
this invention to be as follows:-
This invention has for its object chiefly the lateral adjustment of the pedal to
the width of the foot in a simple and effective manner, and consists in the improved
construction of the pedal to that end.
According to this invention I use a cylindrical sleeve which forms the centre
and bearing of the pedal. The frame of the pedal I make in two sections, each
section so formed that it may be clamped to the sleeve or centre, independently of
the other, and may be moved along the sleeve towards or away from the other, so
as to narrow or widen the tread.
To this end each section is preferably made of two equal sized plates of stamped
metal suitably pierced to obtain lightness. Those edges forming the ends and
sides of the pedal or frame have suitable projections formed upon them to prevent
the foot from slipping and to retain it centrally upon the pedal.
Each section of two plates is clamped to the sleeve or centre preferably by
means of two screw bolts connecting the plates.
In some cases, as for instance where rubber treads are used, we propose to clamp
to the sides of the sections by means of plates and screws, india-rubber tread
pieces. Or we may force the india-rubber tread pieces into suitably formed
cavities in the plates.
Dated this 8th day of November.

Improvements in Pedals for Velocipedes.
We, SAMUEL TWEEDALE and JAMES CLEGO, Directors of the Firm of,
S. Tweedale & Co. Limited, Haugh Cycle Works, Oldham Road, Rochdale, in
the County of Lancaster, Cycle Manufacturers, do hereby declare the nature of
this invention to be as follows :-
This invention relates to pedals for velocipedes and has for its object chiefly
the lateral adjustment of the pedal to the width of the foot in a simple and
effective manner, and consists in improved constructions of the pedals chiefly to
that end.
According to the invention we make the frame of the pedal in two sections, each.
section so formed that it may be clamped to the sleeve of the pedal, independently
of the other and may be moved along the sleeve towards or away from the other
so as to narrow or widen the tread, or shift the same relatively to the crank.
On the drawing appended hereunto
Figs. 1, 2 and 3, show a front view, top view and section of a "rattrap" pedal
with our improvements applied thereto and Figs. 4, 5 and 6, show similar views of
an improved adjustable pedal with india rubber treads..

page_text: On the drawings a denotes the pedal sleeve or bush and a' the stud or crank
pin on which it is mounted, these parts being arranged in any usual way.
In the improved "rattrap" pedal shewn by Figs. 1, 2 and 3, the frame consists
of two sections, each formed of an upper plate 6 and a lower plate c. These
plates are bent as shewn by Fig. 3 so as to pass each about half way round the
sleeve a in their middle part, but leaving a small clearance between them, and are
bent up at the ends, forming the serrated edges b c for the foot, with side
checks. They are pierced with openings to obtain lightness. The two
plates b and c are drawn together by means of screw bolts d and thereby caused
to clamp the sleeve a firmly. When the screw bolts are slackened, each section
can be shifted on the sleeve independently of the other and the width between
the side checks b and c c altered to suit the foot of the rider, and the combined
tread formed by the two sections moved to some extent nearer to or further from
the crank pin.
When indiarubber treads are used, we may use sections with plates similarly
shaped as those for the rattrap pedal with bent up ends but without saw teeth on
them, and bolt the rubber treads to the sides of the turned up ends. Preferably
however we form the sections as shewn by Figs. 4, 5 and 6. Each section of the
pedal is composed of two plates ƒ and g with rubber treads e. The lower plate f
is made the full length of the pedal and bent round at each end so as to form
beadings and is cut out next to each beading so as to form an opening f into
which the tread can be pushed, as shewn in the bottom half of the right hand
section on Fig. 5, which represents the plate f, with the rubber tread and top.
plate g removed. The upper plate 9 is shorter and likewise bent at its ends so
as to form beadings g¹ which when the plates are put together enter into the
openings. The rubber treads are formed with lateral grooves corresponding
to said beadings f¹ and g¹, as shewn by Fig. 6, so that when they have been
pushed through the openings and the top plates 9 are put into their places, the
treads are supported and firmly held by the beadings at the ends of the plates.
The plates and 9 are bent to pass nearly half way round the sleeve a and drawn
together by screw bolts h, which allows each section of the pedal to be shifted on
the sleeve a independently of the other. This arrangement for fixing rubber
treads may also be used for pedal frames of the full width.
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:
1. The construction of pedal frames for velocipedes in sections adjustable on the
pedal sleeves independently of each other substantially as herein before described
and illustrated by the drawings.
2. The construction of a pedal frame for a velocipede in two sections each
composed of two plates clipping and adjustable upon the pedal sleeve, said plates
being formed with serrated edges or having rubber treads attached to them,
substantially as herein before described.
3. The construction of "rattrap" pedals for velocipedes substantially as herein-
before described with reference to Figures 1, 2 and 3, of the drawings.
4. The construction of velocipede pedals with rubber treads substantially as
herein before described with reference to Figures 4, 5 and 6 of the drawings.
5. The method of fixing rubber treads in velocipede pedals substantially as
herein before described and illustrated by Figures 4, 5 and 6 of the drawings.
