Improvements in Attaching Pedals to Velocipedes.
THOMAS CADD No. 7 Pleasant Terrace Wynn Street Birmingham, Engineer's and
Machinist's Fitter, 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 :-
The object of this invention being, to be able to detach the pedal from the crank
without the use of spanner, screwdriver, or any kind of tools, so that in storing the

page_text: machine the pedals can be instantly detached, thus takeing up less room, and in a
case where people have to pass and repass the machine while standing preventing
them catching their legs or dress against the projecting pedals. Also as a means for
preventing the machine being stolen while left unattended, by removeing one or both
pedals and putting them in the pocket of the owner, the machine is at once made
unrideable, thus preventing anyone getting on the machine and riding off with it,
which is generally the case of a cycle theft.
I propose to accomplish this object by a modification of the two methods mentioned
in my Provisional Specification, refering to the drawings, Fig. (1) is a front view of
crank with pedal not in its proper position but placed parallel to machine, the stalk
on pedal spindle shown with dotted lines, is free to lift out of hole in upper part of
crank, also to move round into its proper position.
The upper part of crank has a crosspiece H, Fig. (1) in which is cut a parallel slot N.
A hole is bored in upper part of crank and slightly tapered at D. A hole is made in
crosspiece at B. A lever G. is pivoted to crank at I. One end of lever has a slot V.
The other end has a hole A 2. and on the extreem end is a small projection C 1. On the
lower part of crank is a small stud A 1. The pedal is shown at E. On the end of
pedal spindle is a hoblong block C. (it is seen better on Fig. 2) on the end of block
is attached a screw or stud A. There is also attached to hoblong block, a stalk, that
fits in the hole bored in the upper part of crank, as shown with dotted lines.
The pedal is attached by placeing the stalk that is attached to pedal spindle, into the
hole bored in the upper part of crank (Fig. (1) shows this accomplished) then the pedal
is turned on its stalk into its proper position, and by so doing the end of block C. fits
into slot at N. and the screw A. passes through the hole at B. and projects at the back
part of crank, thus tightening the stalk in its hole, and preventing the pedal from
moveing, except in one direction, and that is to move back the same way it has been
moved forward, to prevent this, the lever G. is turned on its pivot I. and comes under
the head of screw and back part of crank as shown at A. Fig. (1), and so makeing the
pedal rigid to the crank, the hole in lower part of lever A 2. fits on stud A 1 and the
lever is kept in position by spring of lever itself, the projection C 1 Fig. (14) is for
the thumb and finger to hold, to move the lever by Fig. (1) is a side view of crank
Fig. (1) with the pedal in its proper position.
To detach the pedal, the projection on lever C 1. is caught hold of by the thumb and
finger, and pushed off the stud A 1 on crank, the upper part of lever G. moveing from
under the screw A. The pedal C. is then moved round on its stalk D. (it will then
appear as in Fig. (1). The pedal with stalk attached, is then lifted out of the hole
bored in crank, it is then detached, takeing about five seconds to detach it.
Fig. (2) is a front view of crank with the pedal turned round to show the back part of
block C. in this case, the stalk is attached to the crank, instead of the block as in
Fig. (1) and the hole is bored in the block Cinstead of the crank as in Fig. (1) the pedal
is attached and detached in the same manner as in Fig. (1) and the same letters refer
to the different parts as in Fig. (1) and (14).
Refering to Fig. (14) a sliding lever may be employed instead of a pivoted lever, by
attaching a stud or screw at I. on crank, and another about two inches lower down the
crank, the lever to have two hoblong slots cut in, to slide on the smaller part of screw
..or studs, and to he underneath the heads of the said screw or studs, the lever would
then move freely up and down the back part of crank, and move under the head of
screw attached to block at A. and kept in position in the same manner as pivoted
lever at A 1.
The hoblong block C. Fig. (2) may be made solid to the pedal spindle, or separate,
and fastened to the pedal spindle in the usual manner with a locknut at the back of
block. I prefer it to be solid, as it would be simpler in construction and neeter in
appearance.
Instead of the end of block C. fitting into the slot N. a projection on the end of
block, and underneath the screw A. could be left on, to fit into the hole at B.

page_text: 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. In a pedal attachment for velocipedes, the pedal being secured to the crank by a
pivoted lever moving under the head of a screw or stud, the pedal being released, and
instantly detached by moveing the said lever on its pivot, from under the head of said
screw or stud, substantially as described and shown."
2. In a pedal attachment for velocipedes, the pedal being secured to the crank by
a slideing lever, moveing under the head of a screw or stud, the pedal being released
and instantly detached, by slideing the said lever from under the head
of the said screw or stud, substantially as described.
3. In a pedal attachment for velocipedes, the combination of a crank with a stalk
on the upper part of crank. The end of pedal spindle is drilled to fit on stalk, and a
screw or stud is also attached to end of pedal spindle, the pedal is attached by
placeing the end of spindle, that has the hole drilled in, on the stalk on crank,
then turning the pedal into its proper position, the screw or stud passing through
the slot in the upper part of crank at the same time, a lever is moved under the
head of screw or stud, thus secureing the pedal to the crank substantially as described
and shown.
4. In a pedal attachment for velocipedes, the combination of a crank with a hole
drilled in the upper part, and a slot cut in the upper part of crank, the end
of pedal spindle has a stalk attached to fit into the upper part of crank, a screw
or stud is attached to the end of pedal spindle. The pedal is attached, by placeing
the stalk that is attached to the end of pedal spindle, into the hole in the upper
part of crank, then turning the pedal into its proper position, the screw or stud
passing through the slot in the upper part of the crank at the same time, a lever is
moved under the head of the screw or stud, thus secureing the pedal to the crank.
Substantially as described and shown.
