IMPROVEMENT IN PEDALS FOR VELOCIPEDES
Year: 1885

page_text: I, CHARLES JOHN MORGAN of 20 Hanway Street Oxford St London W. in the
County of Middlesex, Engineer do hereby declare the nature of my invention
for IMPROVEMENT IN PEDALS FOR VELOCIPEDES to be as follows:-
My Invention consists of employing in pedals a rotary and oscillating movement
independently of that given by the crank, thereby being self adjusting which gives
a firm hold on the pedal and at the same time allows a more natural movement of
the riders foot.
I do not claim any particular method of fixing or connecting this pedal to the
crank.
In this pedal I employ two metal plates and a bar placed above each other.
The top foot plate or disc revolves on the under plate by a collar stud or stud
pin in the centre, which gives the rotary motion.
The under side of bottom plate is connected to a bar about 4 inches long by
means of two loosely fitting studs or pins forming a hinge which allows the plate
above to oscillate at right angles with the foot of rider thereby making the pedal
rotary and oscillating to meet the foot in any position.
The manner of fitting this pedal is, by the bar being firmly fixed upon the
ordinary rubber pedal now in use, by means of small bolts and plates, and in such
manner as to allow sufficient space for the oscillatory movement of the plate with
disc above.

I, CHARLES JOHN MORGAN, of 20 Hanway Street Oxford Street, W. London in
the county of Middlesex Engineer do hereby declare the nature of my invention
for IMPOVEMENT IN PEDALS FOR VELOCIPEDES 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 certain improvements in pedals, by employing certain
novel movements in connection therewith and in such manner as to allow the rider
a free and natural movement of the feet without losing the hold or position on the
pedals and thereby avoiding the painful tension usually experienced in the feet and
legs caused by the feet being held in one position to avoid the wriggle which
throws the foot off the pedal.
The movements of this pedal is of a Rotary and Oscillating character inde-
pendently of the movement on the crank pin.
For the manner of carrying out my invention, and that it may be more fully
understood I append a sheet of illustrative drawings to which I now refer, the
same letters of reference indicate similar parts in all the figures where they occur.
In describing this pedal having a rotary or part rotary and oscillating movements
which I claim as my invention and that my desciption may be more readily
understood I shall treat it as stationary on the pedal pin.
The plan of the pedal is shown in Figure 1.-A is a circular plate of steel
studded with points to hold the foot from slipping-this plate revolves or partly
revolves on a collar or washer fitting on the bottom plate B and secured by a stud
pin through the centre.
On the underside of the bottom plate B, Figure, 2, is a loop G, to receive the pin
at the end of the bar, C, which moves in the slot formed by the loop G.
D, shows the sides of the bottom plate turned under and forming a ridge to take
the bearing on the rubber as shown in Figure, 6.
The bar C Figure 4 is provided with holes to receive the small bolts and nuts, E,
which pass through corresponding holes in the plate, F.
Figure 3, shows side view, Figure 4 shows the under side of pedal with plate; F,
and bolts, E, removed.
Figure, 5, represents the pedal fixed to the ordinary rubber pedal, Figure, 6,
shows Figure, 2, fitted on the ordinary rubber pedal.
The manner of fixing is as follows, the bar, C, is drawn down into the rubber by
the bolts and plate until sufficient resistance is given to the ridges, D, to support
the plates in position as shown, and at the same time allowing the plate, B, to
oscillate by the ridges, D, sinking into the rubber, when pressure is brought to bear
on the rotary plate, A, by the foot.
The loop, G, holds the plate in position also allowing of a downward movement
which immediately returns to the position as shown, by the elasticity of the rubber
acting on the ridges when the pressure of the foot is removed.
Figure, 7, shows the pedal fitted on to the ordinary pedal with the side plate
removed.

page_text: The term used, part rotary implys only a portion of the revolution to be
performed by inserting a stop or, check between the plates and only giving
Bufficient movement for the foot to be turned from right to left, and vice versa.
Also a square or narrow plate can be substituted for the circular plate A and
having the same deflection for the same purpose and object.
This form of pedal as shown in drawing can be fitted to nearly any rubber pedal
now in use, and which I prefer instead of making the complete pedal-nevertheless
holding the right to do so and in such form and shape as may be required and best
suited for the movements and purposes herein described, and forming a complete
pedal which will contain the hereinbefore mentioned Rotary part rotary or
deflecting movements, or series of movements, by the means of plates or deflecting
arrangements for the foot, being for the same objects and purposes which forms my
invention.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what
I claim is
First. The employment of Rotary part rotary, or, deflecting movements in
Pedals for Bicycles Tricycles and other Velocipedes, by means of plates, or other
arrangements.
Second. The employment of a oscillating movement in Pedals-for Bicycles
Tricycles and other Velocipedes.
Third. The combination of Rotary part rotary or deflecting, and Oscillating
movements described herein and shown by drawings.
