PROVISIONAL SPECIFICATION.
Improvements in Pedals suitable for Use on Cycles and the like.
I, CECIL WAGENER HOLMES of Friday Street, Leicester, in the County of
Leicester, Cycle Manufacturer, do hereby declare the nature of this invention to
be as follows:-
This invention relates to pedals suitable for use on cycles. One of the objects to
be attained is to make what I may call the framework of the pedal in a single
piece; hitherto these have been generally made with two side pieces and two end
pieces rivetted or otherwise secured together. The precise construction of the
pedal may vary but I will describe the invention as applied to what is known as a
rat-trap pedal, that is one having projecting points intended to engage with the sole
of the rider's shoe.
I prefer to employ a piece of steel or other suitable tube of a suitable diameter
out of which I stamp or otherwise remove diametrically opposite pieces so that the
piece of tube thus presents the appearance of two circular ends and two more or
less flat sides with openings between them, tongues or projections being left where
required to form guards to hold the feet in the proper position upon the pedal or
for other purposes. The edges of the sides may at this same operation or
subsequently be provided with the before mentioned points, and the sides may be
extended into any suitable form, conveniently oval, and the framework of the pedal
will then be substantially completed.
Into the circular ends I insert cone bearings of steel to receive the balls; these
may be secured in any convenient manner as for example by soft soldering if they
are inserted after hardening or they may be brazed, welded or otherwise secured if
they are inserted before being hardened. If found practicable they may be formed
in a solid piece with the rest of the metal when the tube is made. To protect the
pedal pin and bearings I prefer to carry a piece of tube across the centre of the
pedal from one end to the other; this may be secured in the pedal or the bearing
cones in any convenient manner or may even be formed in a single piece with the
bearing cones.
If required rubber foot holds may be used with this pedal and secured in any
convenient manner.

in what manner the same is to be performed to be particularly described and

I prefer to employ a piece of steel or other suitable tube of a suitable diameter
out of which I stamp or otherwise remove diametrically opposite pieces so that the
piece of tube thus presents the appearance of two circular ends and two more or
less flat sides with openings between them, tongues or projections being left where

may be secured in any convenient manner as for example by soft soldering if they
are inserted after hardening or they may be brazed, welded or otherwise secured if
they are inserted before being hardened. If found practicable they may be formed
in a solid piece with the rest of the metal when the tube is made. To protect the
pedal pin and bearings 1 prefer to carry a piece of tube across the centre of the
pedal from one end to the other; this may be secured in the pedal or the bearing
cones in any convenient manner or may even be formed in a single piece with the
bearing cones.
If required rubber foot-holds may be used with this pedal and secured in any

In the drawings
Figure 1 is a side view and
Figure 2 a plan of the blank or tube showing the process of forming the pedal
therefrom.
Figure 3 is a perspective view of the complete pedal.
Figure 4 is a longitudinal section through one of the ends or bearings, and
Figure 5 shows the manufacture of an end plate and bearing socket with separate
connecting bars from a tube; the upper half shows the end plate completed and
the lower half shows it in a similar condition to Figs. 1 and 2.
Like letters represent like parts throughout the drawings.
A piece of steel or other tube of suitable length such as A is taken, and out
of opposite sides are stamped or otherwise removed similar pieces, leaving the tube
approximately as shown at the end X in Figures 1 and 2, still cylindrical and
throughout but with longitudinal openings and tongues B projecting into these
openings.
The semi-circular sides are then flattened out and the tongues B turned up
leaving the tube as shown at the end Y of Figures 1 and 2. The flat sides may
have openings A' stamped out of them for the sake of lightness and also projections
or teeth C Figure 3, on their edges to form a grip for the shoe of the rider. The
sides of the tube are then extended into any convenient form preferably oval as
shown in Figure 3.
Into the ends of the tube are inserted and fixed in any convenient manner as by
sweating, the hard steel cups D which form the ball-races for the ball bearings.
The ends of the pedal are connected with one another by a tube E of steel or
other metal which serves to protect the pedal pin and to keep dust out of the
bearings. The projecting tongues B serve to prevent the foot slipping side-ways
on the pedal. Figure 4 shows the relative positions of the tube A the tube E and
the cup D, E being a ferrule or reduced end of E which fits inside the cup D and
while supporting the latter serves also to keep E in proper alignment.
The cup D could be formed of the tube A but a separate cup is preferred.
Where a pedal of the ordinary construction with end plates and separate
connecting bars such for instance as the ordinary rat-trap pedal is preferred to the
complete framing previously described the tube may be inade as before and shaped
as in Figures 1 and 2 to a suitable length to form the ends only the walls A instead
of continuing from bearing to bearing being then as indicated in Figure 5 turned

page_text: up perpendicular to the axis of the pedal so as to form a straight end F like that
of the ordinary rat-trap pedal the ends being connected by ordinary rat-trap
bars G which may be passed through holes at F in each end of the plate F and
rivetted over in the ordinary manner. By this means the end plates and the
bearings or sockets which contain the bearing cups are made in single pieces out of
tubes as described. In Figure 5 the upper half shows the end plate and socket
completed and the lower half shows it in the form of the right-hand side of Figures 1
and 2. The tongues B are preferably retained as before.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A cycle pedal having the sides and ends made in one piece.
2. A cycle pedal substantially as described and illustrated in the accompanying
drawings.
3. The manufacture of a cycle pedal from a tube by removing diametrically
opposite parts and straightening and extending the remaining walls substantially as
described and illustrated in the accompanying drawings.
4. A cycle pedal having the sides and ends made from one tube from which
diametrically opposite pieces have been removed and the sides extended into a
convenient form substantially as described and illustrated in the accompanying
drawings.
5. An end plate and bearing socket for a cycle pedal formed out of a tube
substantially as described and illustrated in Figure 5 of the accompanying
drawings.
