I, WILLIAM CHATER LEA, of 116 to 120, Golden Lane, Old Street, in the County
of London, Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to pedals chiefly designed for use on velocipedes and comprises
the improvements hereinafter set forth.
According to my said invention I provide a taper or other spindle which forms the
pedal pin and which spindle is adapted to pass loosely into a sleeve or barrel fixed,
as hereinafter described, between the end plates of the pedal. At one end of the
pedal pin (preferably that nearest the crank) a suitable collar is provided whereon is
formed a ball-race or path, between which ball-race or path, and a corresponding
ball-race or path upon a collar screwed into an enlargement provided at that end of
the outer sleeve or barrel are placed a row of balls thus providing for the support of
the inner or one end of the said outer sleeve or barrel upon the taper or other spindle
or pedal pin.
At the other extremity of the said pedal pin is formed a conical hole or
countersink in which engages the corresponding tapered end of a set-screw which
passes through a suitably screw-threaded hole in the end of the outer sleeve or
barrel, thereby adjustably and rotatably supporting that end of the latter upon the
said pedal pin.
The end plates of the pedal are secured to the sleeve or barrel, the one, or outer
plate, by a nut adapted to screw upon the above mentioned taper or conical ended
set-screw, which nut serves the double purpose of securing the said outer end plate
and of locking the adjustment by clamping the former against the end of the said
sleeve or barrel, or against a collar or enlargement thereon; the other, or back plate,
by the before mentioned combined screw collar and ball race, which is adapted to
pass through a hole provided in the said plate, and screw into the herein before
inentioned enlargement upon the inner or crank arm end of the sleeve or barrel and
clamp the said plate against the latter, suitable holes or countersinks being provided
upon the outer surface of the said collar so as to enable it to be operated by means
of a pin or peg wrench or spanner. When screwed up the above mentioned collar
will be locked in position, and the end plate firmly clamped or clipped between it
and the end of the sleeve or barrel, and the collar of one pedal (when two
pedals are employed as in the case of a cycle or the like) is preferably provided
with a left hand thread, and that of the other pedal with a right hand thread.
The inner or that extremity of the pedal-pin intended to be secured in the end of
the crank-arm is screw-threaded, and may be fixed in position by means of a conical
nut or in any convenient or well-known manner.
I may for the hereinbefore mentioned sleeve or barrel cylindrical and of uniform
diameter from the enlargement at the inner end, to the other or outer end thereof,
or I may in some instances cause it to taper from the said enlargement to the said
outer or other end thereof. I form upon the said outer end, moreover, a reduced
portion of slightly less length than the thickness of the end plate of the pedal; and

page_text: I provide in the said end plate a D or other conveniently shaped hole or aperture into
which the said reduced portion is adapted to fit and wherein it is thus prevented
from turning. When the sleeve or barrel is formed taper I preferably provide a collar
or enlargement against which the end plate of the pedal may rest when fitted upon
the said reduced portion, and forming a sufficient surface against which to clamp it
by means of the hereinbefore mentioned nut.
I, WILLIAM CHATER LEA, of 116 to 120, Golden Lane, Old Street, in the County
of London, Engineer, do hereby declare the nature of this invention and in what
imanner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
My invention relates to pedals, chiefly designed for use on velocipedes, and com-
prises the improvements hereinafter set forth.
In the accompanying drawing,
Figure 1 is a plan, and
Figure 2 is a vertical longitudinal section on the line, Figure 1, showing one
form of my improved pedal.
Figure 3 is a sectional view showing a modification.
Like letters indicate corresponding parts throughout the drawing.
a, a are the end plates of the pedal, and b, b are the longitudinal or foot plates
thereof.
According to my invention I provide a taper or other spindle c, which forms the
pedal pin, and which spindle is adapted to pass loosely into a sleeve or barrel d
fixed, as hereinafter described, between the end plates a of the pedal. At one end
of the pin c (preferably that nearest the crank) a suitable collar c¹ is provided whereon
is formed a ball-race or path c² between which and a corresponding ball-race or
path e¹ upon a collar e screwed into an enlargement provided at that end of the
outer sleeve or barrel d, are placed a row of balls f, thus providing for the support
of the inner or one end of the said outer sleeve or barrel d upon the taper or other
spindle or pedal pin c.
c3 is a conical hole or countersink formed at the other extremity of the said pedal
pin c in which hole c³ engages the corresponding tapered or conical end of a set-
screw which passes through a suitably screw-threaded hole in the end of the outer
sleeve or barrel d, thereby adjustably and rotatably supporting that end of the latter
upon the said pedal pin c.
The end plates a of the pedal are carried on the sleeve or barrel d. A reduced
portion d² is provided on the said sleeve or barrel d of slightly less length than the
thickness of the end plate a of the pedal, and a D or other conveniently shaped hole
or aperture a¹ in the said end plate a into which the said reduced portion d² is adapted
to fit and wherein it is thus prevented from turning. d³ is a collar or enlargement
upon the sleeve or barrel d against which the end plate a of the pedal may rest when
fitted upon the said portion d², and h is a nut adapted to screw upon the above
mentioned taper or conical ended set-screw 9, which nut serves the double purpose
of securing the said outer end plate a and of locking the adjustment by clamping the
former against the end of the said sleeve or barrel d, or against the collar or
enlargement d³ thereon. The other, or back plate a, is secured to the said sleeve or

page_text: barrel d by the before mentioned combined screw-collar e which is adapted to pass
through a hole provided in the said plate, and screw into the herein before mentioned
enlargement d¹ upon the inner or crank end of the sleeve or barrel d and clamp
the said plate against the latter, suitable holes or countersinks e² being provided upon
the outer surface of the said collar e¹, and two or more flats e³, so as to enable it to
be operated by means of a pin or peg wrench, or a spanner, or otherwise. When
screwed up, the above mentioned collar e will be locked in position and the end
plate a firmly clamped or clipped between it and the end of the sleeve or barrel d,
and the collare of one pedal when two pedals are employed, as in the case of a cycle
or the like, is preferably provided with a, left-hand thread, and that of the other
pedal with a right-hand thread.
The inner or that extremity of the pedal-pin c intended to be secured in the end
of the crank-arm is screw-threaded as shown at c' and may be screwed or fixed into
position and locked by means of a lock nut i or in any convenient or well-known
manner.
In the modification illustrated in Figure 3 the countersink c' at the outer end of
the pedal pin c is enlarged, as shown, so as to form a ball race c³, and a row of
balls are provided for supporting the pedal pin c upon the tapered or conical end
of the set-screw g, and so tending to reduce friction.
The sleeve or barrel d may be formed either cylindrical and of uniform diameter
from the enlargement d¹ at the inner end to the other or outer end thereof as shown
in Figure 3, or tapered from the said enlargement d¹ thereon to the outer or other
end thereof as shown in Figures 1 and 2.
The reduced portion d² of the sleeve or barrel d is dispensed with in the arrange-
ment shown in Figure 3.
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. An improved pedal for use upon velocipedes and the like wherein the end
plates are rotatably mounted or supported upon the pedal pin at the inner or one
end upon a row of balls, and at the outer or other end upon an adjustable conical
or point bearing, substantially as described.
2. An improved pedal for use upon velocipedes and the like wherein the end plates
are rotatably mounted or supported upon the pedal pin at the inner or one end upon
a row of balls, and at the other or outer end upon a conical or taper ended screw and
row of balls, substantially as described.
3. The improved pedal for use upon velocipedes or the like constructed substan-
tially as described with reference to Figures 1 and 2 or to Figure 3 of the
accompanying drawing.
Dated this 2nd day of December 1897.
