PROVISIONAL SPECIFICATION.
Improvements in and relating to the Pedals and Pedal Attachments
of Cycles.
I, ALFRED HENRY WEBSTER, of 394, Monument Road, Edgbaston, Birmingham,
Cycle Works Manager, do hereby declare the nature of this invention to be as
follows:
This invention consists in forming the pedal bearing or axis hollow through its
entire length, the inner sides of which can be either tapered or parallel with the
exterior sides, this hollow bearing or barrel carries ball races at each end for the
ball bearings. It is hardened and tempered in the usual manner. Through each
hollow pedal bearing is inserted a soft metal pin extending a slight distance on
either side, the one end has a conical head and is screw threaded on the inner side
of said head to receive a nut, the other end is drilled and tapped to take a locking
bolt of suitable form which secures the pedal to its bearing.
In attaching the pedal to the crank of a cycle I remove the locking bolt and
withdraw the pin from the hollow bearing or barrel, the solid pin is then, inserted
from the inner side of the crank face which has a conical hole recessed in same to
correspond with and to receive the conical head of the nin, the locking nut is now
tightened up on the outer face of said crank the barrel bearing of the pedal is then
passed on to the pin and secured by means of the locking bolt or similar device.

Improvements in and relating to the Pedals and Pedal Attachments
of Cycles.
I, ALFRED HENRY WEBSTER, of 394, Monument Road, Edgbaston, Birmingham,
Cycle Works Manager, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement, reference being had to the drawings
forming a part of this specification and to the figures and letters shewn upon
same:-
Figure 1 represents my improved arrangement of pedal and pin attachments
shewing pedal crank partly in section.
Figure 2 is an end view of pedal. Figure 3 is a detail of the other end of the
attachment

page_text: Figure 4 shews a longitudinal section on the line A A.
Figures 5, 6, and 7, details of the nuts and collars.
Figure 8 represents an alternative form of pedal pin and head shewing a pedal
crank in part section as attached. Figure 9, an end view of same.
My invention consists in forming the pedal bearings or axis A hollow through
its entire length the inner sides of which may either be tapered or parallel as
shewn with the exterior sides, this hollow barrel bearing or axis A carries ball
races B at each end for the ball bearings C and is hardened and tempered as in
the usual manner.
Through each hollow pedal bearing A is inserted a steel pin or spindle D
(preferably of soft steel) extending a slight distance on either side of the pedal the
one end is provided with a conical screw head E and is screw threaded as at E¹
to receive a screwed nut F the other end of the said steel pin or spindle D is drilled
and tapped to take a screwed locking bolt G of suitable form. Or instead of a
conical head E on the steel pin or spindle D, I sometimes prefer to employ a
shouldered head as at E2 with a small feather E3 attached thereto as at Figure 8.
In attaching the pedal to the pedal crank I remove the locking bolt G and with-
draw the pin I from the hollow bearing or barrel A, the solid pin D is then
inserted from the inner side of the crank face H which has a conical hole or a
counter sunk hole therein according to the shape of the head to correspond with
and to receive the said conical or shouldered head as the case may be, the locking
nut F is now tightened up on the outer face of said crank the barrel bearing or
axis A of the pedal is then passed on to the pin or spindle D and secured by means
of the locking bolt G or other suitable connecting means.
Many advantages will be found to exist by this improved construction, greater
security is afforded as there are no nuts on the inside of the pedal cranks to work
loose or catch, moreover the width of the tread of crank axle is considerably lessened
by having no nuts on the inside of said cranks, then in the event of the pedal
pins getting bent or damaged from any cause the pedal can be taken off intact
and the pedal pin which is composed of steel (preferably soft as stated) can be
readily straightened or renewed.
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:-
Firstly. In connection with the pedals and pedal attachments of cycles, the
employment of a hollow pedal bearing or axis having tapered or parallel inner
sides and ball races at each end and the application and use of solid steel pins or
spindles passing through said hollow bearings in combination as and for the pur-
pose described.
Secondly. In combination with cycle pedals and pedal cranks and attachments
the employment of the solid steel pins or spindles in combination with the hollow
barrel bearings, forming conical heads or shouldered heads upon said solid pins,
forming conical or counter sunk recesses in the pedal cranks to receive said heads
all for the purpose herein described.
Thirdly. In cycle pedals and pedal cranks the hollow barrel bearings and solid
spindles of hard or soft metal and the means for securing and attaching the parts
consisting of locking nuts bolts and washers all in combination and constituting
my said improvements herein described.
