PROVISIONAL SPECIFICATION.
A New and Improved Width Adjusting Pedal for Bicycles and
Velocipedes.
HENRY WATERSON 67 Albert Road Aston Birmingham, Commercial Traveller,
do bereby declare the nature of this invention to be as follows:-
The purpose of my invention is to construct the frames or bodies of bicycle
& velocipede pedals in such a manner as to provide a sliding variable width of
tread upon such pedals so that the rider may by adjusting the outer pedal plate.
or ears, (the purpose of which are to prevent the foot slipping off the pedal) to
any required distance from the inner fixed pedal end plate or ears, so regulate
the distance between the fixed and movable ends, by the horizontal sliding of
the outer portion of my improved pedal, and so obtain an adjustment in width
which permits of the use of boots or shoes of any convenient size.
I will first describe my invention as it relates to what are known as rat trap pedals
and for the purpose of constructing the same I use an outer end pedal plate
without the usual vertical ears which are provided in the ordinary method of
manufacturing such pedals and I employ a frame of rectangular or other desirable
shape to fit to and slide horizontally alongside the side plates or rat trap hars
forming the frame of the pedal and which sliding frame at its outer end I make
of such shape as to form the ear or ears necessary to prevent the riders foot
slipping off the pedal, whilst by one or more screws passing through the sides of
the pedal body or frame and also through slots in the sides of my sliding and
adjustable ear or distance piece I am able to firmly lock the whole together in any
required position.
In the manufacture of pedals having side bars of rubber or other material, instead
of the metal rat trap bars as before described I also dispense with the vertical ears
hitherto provided on the outer pedal plate and affix to the pin or centre of the
pedal a sliding clip having attached thereto one or more wires or strips of metal
running through or upon the outer end of the pedal frame and by turning upwards
the outer ends of such wires or strips I form the ear or distance piece to prevent
the foot slipping off the pedal and the width or distance between the inner fixed ear
and the outer movable ear is determined by gripping the pin or centre of the pedal
frame by the sliding clip attached to the inner end of such adjustable ears or
distance pieces.
As a further modification of my invention as applicable to rubber pedals, having
as before described, dispensed with the fixed outer ear I affix on the top of or
underneath the india rubber blocks or bars a small angle plate lying at right angles
across such blocks or bars and having slots therein running parallel with the length
of the pedal into which slots I insert screws or bolts the upper ends of which pass
over and clip the pin or centre of the pedal frame thus I am able to securely fix
the angle plate referred to (the vertical side of which forms the movable ear or
distance piece) so as to accomodate a riders boot or shoe of any width.

Velocipedes.
I, HENRY WATERSON, of 67 Albert Road, Aston, near the City of Birmingham,.
Commercial Traveller, 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 relates to improvements in cycle pedals, and has for its object, a
width-adjusting pedal, or a pedal capable of having its breadth regulated to the
width of the tread of the boot or shoe of a rider, and this I accomplish by
providing and fitting to the primary and fixed framing of the pedal, a supplementary
and movable end framing, which is capable of having a variable and sliding
adjustment relative to the off-side pedal plate of the fixed framing, and which said
supplementary framing forms an end in common with the pedal itself.
Figure 1 of the accompanying drawings represents partly in topside plan and
partly in horizontal section, a width-adjusting rat-trap pedal constructed according
to, or provided with improvements made according to my invention.
The said view shows the parts in the relative positions which they assume when
the said pedal is at its normal width, or otherwise, when the supplementary framing,
which constitutes an adjustable end, is collapsed or closed.
Figure 2 represents a side elevation of Figure 1, showing the full arrangement
and disposition of the parts.
Figure 3 shows a cross section of Figure 2 upon the dotted lines A B, and looking
towards the movable and end part of the said width-adjusting pedal.
Figure 4 represents a like topside and sectional view as Figure 1, but with the
supplementary and width-adjusting framing part distended or drawn out, so that
the distance between the inner fixed end pedal plate of the fixed framing and the
pedal plate of the movable framing is adjusted, according to the breadth of the
shoe of a rider.
Figure 5 represents a side elevation of Figure 4.
Figure 6 represents a plan of the movable or extension part separately.
Figure 7 is an edge view of the same.
Figure 8 is a plan of the fixed part of the said pedal separately.
In Figures 1 to 8, a is the inner and fixed pedal, having a covered centre or
hub b, (wherethrough the spindle 63, passes) and ball-bearing head ends 12, and
fixed pedal-plate ends c, e, the latter c², being set down or the top edges of the same
disposed at a lower plane than the toothed tops d³, of the sides d.
e is a U-shaped supplementary extension framing, composed of an end bar or
pedal plate e', and side plates e, of an inside breadth equal to the out-side cross
width of the pedal, and which work upon the sides, whilst stops e, of the fixed
end e², take and work within guide and limiting slots e³, formed within the sides e
of the supplementary frame e, which sides have near their ends, clamping pins f
directed through them and through slots d³, made longitudinally within the sides d,
of the fixed part of the pedal a.
Now the end e¹, of the extension part e, has an ear or lip e, which is slightly
inclined outwardly, and forms with the one c', at the fixed end, leads for the shoe,
and stays to prevent the same from slipping off the pedals.
It may be also observed that the end plate e', has a middle clearance or hole e,
to admit of the outer end 2, of the covered centre of the fixed framing to extend
outwardly through, to allow of the extension end of the pedal being collapsed or
closed as in Figures 1 and 2.
The shanks, of the pins or bolts f, are square, so as to admit of the movable
part being readily clamped to the fixed part and with interposed washers f³,
between the nuts f" and framing.

page_text: Now assuming that the breadth of the pedal requires to be regulated to the
breadth of a shoe, and that the parts of the pedal are in the positions as represented.
in Figure 1, loosen the nuts 2, when the supplementary frame or extension part is.
capable of being drawn out as in Figure 4, and the distance between the fixed
sides c, of the fixed pedal frame a, and the side of the extension frame e, adjusted
hy horizontally sliding the same into an adjusted position such as in Figure 4.
Then by screwing up the nuts 2, the movable frame is affixedly clamped to the
fixed frame, thereby forming a pedal with an extended breadth, or a pedal with an
adjusted breadth. It will be seen that the outer pedal plate end c², leaves a perfect
clearance for the foot by the top edges of the pedal plates coming above the top of
the outer head b.
Figure 9 represents a rat-trap pedal arranged according to a modified form of
my invention, (but which is equally applicable to rubber pedals) in which the
extension or supplementary part is carried by stalks or long pegs, which take into
ad slide horizontally within sleeves or sockets, carried by the outer pedal plate of
the fixed framing.
Figure 10 represents a transverse vertical section of Figure 9 upon the dottedl
lines C D.
This said view shows the position of the set screws for affixing the supplementary
or extension part of the pedal to the fixed part after adjustment.
a is the pedal, c² is the pedal plate or side of the outer end having tubular sockets
or sleeves c³, disposed on the two opposite sides of the head of the covered
centre, and in the direction of the pedal axis, and with stalks or pegs e², of the
extension side e', of the movable part e, passing through and being longitudinally
adjustable within the said sockets or sleeves and there clamped in any desired limit
of adjustment by screw pins, passing through tapped holes in the sides or walls of
the sockets or sleeves c³, when by the screwing up of the said pins, their ends are
made to impinge upon the stalks or pegs e².
Figure 11 represents a pedal (with the fixed end broken away) constructed
according to a still further form of my invention. In this arrangement, which is
alike unto Figures 9 and 10, the stalks, instead of passing through sockets, pass
through holes in the outer fixed ends of the fixed framing, and slide longitudinally
at the backs of the sides of the said fixed framing, and also through the eyes of
eyed bolts or pins, on the wormed parts of the said pins being loosened.
a is the fixed framing of the pedal, and the outer pedal plate, lying with the
head of the covered centre clear of the plane of the tops of the sides of the
said pedal frame, and working through holes e, in the said ends, adjacent to
the inside faces of the sides d, are stalks or stems e, carrying at their outer ends, a
pedal plate el, of the extension part e.
These said stalks or stems e, also pass through eyes 72, of eyed pins f, whose
sbanks pass through holes d, in the fixed part of the framing, so that by loosening
the nuts, the grips of the eyes are released, and the movable framing e, is capable
of being slid in or out and adjusted longitudinally, and distance between the fixed
inner end pedal plate and the pedal plate of the extension part varied and adjusted
to the breadth of a shoe.
Figure 12 represents a topside plan of a pedal (with the fixed end broken away)
constructed and provided with improvements made according to a further form of
my invention,
Figure 13 is an underside plan of Figure 12, and Figure 14 is a section on the
dotted lines - Figure 12.
The said arrangement represents the extension principle applied to a rubber
pedal, and is carried out by fitting the underside of the framing with a supple-
mentary and sliding plate with a turned up or angle end forming the pedal plate,
whilst the said attachment incidentally acts as a counterpoise, which always brings
the upper side of the pedal or the tread thereof uppermost.
Q
the framing, bis the covered centre and the heads thereof. 9 are the

page_text: rubber treads, threaded on axial pins g², with nuts at their ends coming at the back
of the general framing.
e is the extension part, having a front plate e', and lip et, and under plate e²,
whilst the plate el, has a clearance e, alike unto the other arrangements, for the
head 2, of a covered centre b, to pass through whilst the plate 2, has slots e,
wherethrough the screwed ends e, of a staple loop e, pass through and are secured
by screwing nuts e³ thereon.
Further the said plate is guided and steadied in its horizontal movement by
fixed studs, coming between the covered centre b, and the rubber treads g.
Figure 15 represents in full plan, a further form of my invention applied to a
rubber pedal.
Figure 16 represents the movable end of the same.
In this arrangement, the extension, or movable and supplementary end part, is
carried by or secured in position through the medium of a clip, which embraces the
tubular middle member through which the spindle passes.
d is an ordinary fixed frame, y are rubber treads, is a tubular body part, having
fitted to it, a clipe, carrying an outwardly extending member e, terminated by an
upwardly directed ear or guard e¹.
To regulate or adjust the breadth of the pedal, loosen the screws, of the clip,
and then slide the said clip upon the tubular member or covered centre h. Then
turn the screws, when the clip is drawn tight, the movable end part secured and the
necessary adjustment made.
Figure 17 represents a side elevation, partly in section, of a rubber pedal (with
the fixed part broken away) provided with an adjustable end constructed according
to a still further modification of my invention, which is equally applicable to rat-trap
pedals.
is the tubular body member or covered centre, through which the spindle i,
whose outer end is inside screwed, passes, whilst directed up the said screwed end,
and through the lock-nut j, is a screwed stalk or stem e, having loosely fitted to its
end, a horned end plate e, whilst coming between the said horned plate and the
nut, is a supplementary screwed lock uut k, which when screwed home, affixes the
extensible stalk e², in any adjusted position. By my invention the nests of balls
constituting the bearings are un-interfered with, as the supplementary and adjustable
ends are independent of the said bearings.
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 :-
:-
First In cycle pedals, employing in conjunction with a fixed framing having
sides and ends, and provided with bearings, a supplementary and adjustable loose
end, substantially as and for the purpose as described and set forth.
