Improvements in Pedals for Bicycles and other Velocipedes and
Motor Vehicles.
We, JAMES WILLIAM BROOKS, of 6, Caldmore Road, Walsall, in the County of
Stafford, Manufacturer, and SAMUEL VALE, of Windmill Tavern, Bath Street,
Walsall aforesaid,. Cycle Maker, do hereby declare the nature of this invention
to be as follows:-
This invention consists of the herein described improvements in pedals for
bicycles and other velocipedes and for those motor vehicles in which pedals are
used.
By this invention we effectually prevent dust from entering the ball bearings
of the pedal and we ensure perfect lubrication and easy working of the pedal.
In carrying out this invention we provide in place of the usual pedal pin, a
short metal tube which is screwed into the end of the crank or is otherwise fixed
thereto or may be formed therewith and extends from the face of the crank for
any convenient distance say to a little beyond the centre of the revolving part of
the pedal. Within this tube is an axle which revolves in ball races in the ends
of the tube. That end of the axle which is farther from the crank projects
through and is fixed to the central boss of the pedal which is made as a sleeve
and encloses the end and a certain part of the whole of the tube and revolves
around the same. This boss or sleeve is made with projecting side arms say four
in number to which the rat trap, or U-shaped or rubber or other suitable tread
The end of
part of the pedal is fixed by small nuts or other convenient means.
the pedal pin which revolves in the ball race in the crank end of the tube is
fitted with an adjusting cone and is enclosed by a dust proof washer or cap fixed
to the crank.
By the ball races being enclosed in the tube and the pedal pin revolving in the
same as above described the bearings are effectually protected from dust and
moreover the tube forms a reservoir for the oil which works therefrom into the
ball races.

page_text: Walsall, aforesaid, Cycle Maker, 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 consists of the herein described improvements in pedals for
bicycles and other velocipedes and for those motor vehicles in which pedals are
used.
By this invention we effectually prevent dust from entering the ball bearings
of the pedal and we ensure perfect lubrication and easy working of the pedal.
We will describe this invention by referring to the accompanying drawings on
which rig. 1 is an elevation of a cycle pedal constructed according to this inven-
tion shewing also a part of the crank to which the pedal is fixed; Fig. 2 is a
longitudinal section of the same; Fig. 3 is an elevation and longitudinal section
of the revolving tread part of the said pedal separately; Fig. 4 shews other parts
of the said pedal separately; Fig. 5 shews a portion of the tread represented by
Fig. 3; Fig. 6 illustrates a modification of the revolving axle part of the said
pedal; Fig. 7 is an elevation partly in section of a modification of this invention;
Fig. shews separately the tread and axle portion of the pedal represented by
Fig. 7; Fig. 9 is a sectional plan and Fig. 10 is a longitudinal sectional elevation
and Fig. 1 is a cross sectional elevation of a modified form of the revolving
part of the pedal represented by Figs. 1 and 2; and Fig. 12 shews the tread
represented by Figs. 9, 10 and 11 in process of manufacture from a piece of cold
drawn steel tube.
The same letters of reference indicate the same or corresponding parts. in all
the figures.
This invention is carried out as follows:-We will first describe the arrange-
ment shewn by Figs. 1 to 4 both inclusive. We provide, in place of the usual
pedal pin, a short metal tube A which at a¹ is screwed into the end of the
crank B or is otherwise fixed thereto, or this tube A may be formed in a piece
with the crank, and extends from the face of the crank for any convenient dis-
tance say to a little beyond the centre line XX of the revolving part of the
pedal. Within this tube A is an axle C shewn separately in Fig. 4 which
revolves in ball races d'd in the ends of the tube A. The end part c¹ of the
axle C which is farther from the crank B projects through and is fixed to the
central boss E on the revolving part of the pedal which boss E is made as a
sleeve and encloses the end and a certain part of the whole of the tube A and
revolves around the same. The boss or sleeve E is fixed on the end c of the
spindle by the nut c³ and is kept square with the spindle by fitting against the
collar formed thereon. The boss or sleeve is made with projecting side
arms, say four in number, marked respectively eeee to which the rat-trap or
other tread bars FF2 of the pedal are respectively fixed by the nuts g screwed
on the ends of the side arms eeee or by other convenient means. The end c
of the axle C which revolves in the ball race da in the crank end of the tube A
is fitted with an adjusting cone H¹ and lock nut H2 and enclosed by a dust-
proof washer or cap I which latter is screwed into the open end of the tube A
and assists in locking the same to the crank. On the exterior of the tube A
there is formed a collar a² to close the end of the sleeve E and prevent the dust
entering the same or instead of this collar a³ a cap or other means may be used
to close the end of the sleeve E.
By the ball races d'd being enclosed in the tube A and by the pedal pin C
revolving in the same as above described, the bearings dd are effectually pro-
tected from dust and moreover, the tube A forms a reservoir for oil which is
fed into the same through the oil hole k and works therethrough into the ball
races d². By first removing the nut c³ the revolving tread part of the pedal
can be removed from the axle C and replaced by a treadpart of a different kind
made for instance with rubber treads instead of rat-trap shewn.
It will be evident that our invention not limited to the precise details of

page_text: construction shewn by Figs. 1, 2, 3 and 4. For instance instead of the end ct of
the spindle C which is nearer to the crank being provided with the adjusting
cone H' and the lock nut H2 as above described, this end ct of the spindle C may as
shewn by Fig. 6 be made with a solid collar forming part of the spindle C
and to form the ball race. The adjusting cone H¹ is in this case screwed on to
the other end of the spindle C at c or by other convenient means. The holes in
the tread bars FF which receive the ends of the arms ele³ ³ may if desired
be slotted as is the hole f¹ in Fig. 5 so that the tread bars F1 F2 can be moved
nearer to or farther from the crank B according to the width of the rider's foot
and fixed in any desired position by the nuts g.
In the modification of this invention as applicable more particularly for racing
pedals (see Figs. 7 and 8) we make the side arms ele e³e in a piece with the
axle C itself thus somewhat reducing the weight of the pedal.
Figs. 9, 10 and 11 shew how the combined sleeve E and arms e¹³ ³ and
tread bars FF can all be made together in one piece from a cold drawn seamless
steel tube which as shewn in Fig. 12 is slit longitudinally along the centre 23
and the halves of the tube are then flattened thus forming a sleeve part E and
two flat bars F1 F2 projecting from the end of the same as shewn in Fig. 12 which
bars Fare afterwards bent outwardly and back parallel with the socket E so
as to form the two tread bars F1 F2 of the pedal and the two arms e³e which at
one end secure these tread parts to the socket E (see Fig. 9). The bars F¹ Fare
then bent backwardly towards each other as at e¹ e² and then bent parallel against
and secured to the socket E at 2 thus forming the combined sleeve E and
tread bars FF2 of the pedal. In the sleeve E there is brazed or otherwise fixed
a collar e to take on to the end c¹ of the axle C.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:
1. In a pedal for bicycles and other velocipedes and motor vehicles, the com-
bination of a tubular part formed with or adapted to be fixed in the crank, an
axle within said tube projecting beyond the end thereof farther from the crank
and revolving in ball bearings at or near the ends of the tube, and a tread part
fixed to the said projecting end of the axle so as to revolve therewith, all sub-
stantially as described.
2. In a pedal for bicycles and other velocipedes and motor vehicles, the com-
bination of a tubular part formed with or adapted to be fixed in the crank, an
axle within said tube projecting beyond the end thereof farther from the crank
and revolving in ball bearings at or near the ends of the tube, and a tread part
fixed to the said projecting end of the axle so as to revolve therewith and form-
ing a sleeve to enclose the ball bearing, all substantially as described.
