ARTHUR BILLS 10 Union Road Clapham S. W. Cycle Manufacturer do hereby
declare the nature of this invention to be as follows:-
My invention is a ball bearing crank and pedal combined, for propelling purposes
for velocipedes, the end of the crank where the ordinary pedal is fixed, is drilled
through and recessed out on both sides to the radius of balls required, thus the
crank forms the bearing case, which is quite different to any other existing crank,
the pedal is stamped all in one piece, one end of which forms the other part of
the bearing, is turned conical to the radius of balls required, the same end of the
pedal is screwed to receive a loose cone on the other side of the bearing which
forms the adjustment of the bearing also, the extream same end of the pedal is
drilled and tapped out to take a screw which forms a lock screw on the loose cone
and makes the whole bearing firm and secure.

Ball Bearing Crank and
I, ARTHUR BILLS of 10 Union Road, Clapham, S.W. Cycle Manufacturer,
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:-
My invention relates to a ball bearing crank and pedal combined, more
particularly intended for propelling velocipedes, and according to my invention
the end of the crank wherein the ordinary pedal is fixed, is drilled through and
recessed out on both sides so as to form suitable ball races. The pedal is
preferably constructed in one piece, the pedal pin being formed with a coned
portion, forming, in combination with steel balls and one of the recessed parts of
the end of the crank, a part of the ball bearing, while a screw threaded extension
of the pin passes through the crank and receives upon the opposite side a loose
cone, between which and the second recessed portion of the crank are contained
suitable steel balls, thus completing the bearing. The aforesaid screw threaded
end or extension is drilled out and tapped to take a locking pin or stud for firmly
securing the loose cone and retaining the various parts in their respective positions.
In order that my invention may be more fully understood, I will now proceed to
describe same with reference to the accompanying drawings in which
Fig. 1 is a general view of the crank and pedal combined.
Fig. 2 is a plan partly in section of the pedal pin also showing the adjusting nut.
Fig. 3 is a side view with the end in section of a portion of the crank, and
Fig. 4 is a front view of the crank with the bearing cones removed. The loose
cone and locking pin or stud are also shown.

page_text: According to my invention the end b, of the crank c wherein the pedal is
usually secured, is drilled through as at f, and recessed out for a sufficient distance
upon each side as at b', 6, (Figs. 3 and 4), so as to form suitable bearing surfaces
or ball races. The pedal proper consists of the pin or stem's preferably formed
integrally with two arms g, g, arranged at right angles and furnished with or
carrying the foot plates p, p.
The end of the stems (Fig. 2) is formed integrally with the bearing cone a,
which in combination with one of the recessed portions or ball races forms a part
of the ball bearing, while the screw threaded extension d passes through the drilled
out portion of the crank c and receives the loose cone a', which covers the
second recessed portion or ball race, thus completing the bearing, steel balls being
of course interposed between the bearing surfaces.
The screw threaded extension d is drilled out as at d', (Fig. 2) so as to receive
the locking pin or stud d' (which is shown in plan and side view) for the purpose
of locking the loose cone and securing all parts firmly together. The opposite end
of the pedal pin is likewise drilled out as at m to receive the adjusting stud n,
which is furnished with a locking nut n', the said stud being regulated so as to
adjust the width of the pedal.
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 :-
1. The new or improved crank and pedal combination, comprising a crank such
as c, having recessed parts or ball races such as b, 61, formed in the end thereof,
in combination with a suitable pedal pin such as s formed integrally with bearing
cone a, and screw threaded extension d; loose cone a¹, and a suitable locking pin,
stud or the like such as d², the whole combined and arranged, substantially as
herein described and shown, and for the purposes specified.
2. In a crank and pedal combination such as above claimed, the pedal pin s
preferably formed integrally with arms g, g, at right angles thereto, furnished with
or carrying foot plates p, p, the whole in combination with a suitable adjusting
stud n whereby the width of the pedal may be regulated, substantially as herein
described and shown and for the purposes specified.
3. In a crank and pedal combination the formation or arrangement of the
bearing surfaces or ball races within the end of the crank, substantially as herein
described and shown and for the purposes specified.
4. The new or improved crank and pedal combination substantially as herein
described and shown and for the purposes specified.
