Improvements in or relating to Pedal and similar Attachments.
I, SEYMOUR BINGHAM, of Wynhaven 75, Rotterdam, in the Kingdom of Holland,
Manufacturer, do hereby declare the nature of this invention to be as follows:---
This invention relates to the attachment of pedal pins, crank handles and the
like, the object being to so connect the pedal pin, handle etc., with the crank that
it can when desired be folded down so as to lie substantially parallel with the
crank.
In carrying out the invention I pivot the pedal pin or equivalent to the crank
preferably by means of ears or a bracket at the front of the crank, the pedal
pin being provided with a projecting lug or ear to fit between the ears upon the
crank so that the pin when folded may lie substantially parallel with the crank and
when opened out, at right angles thereto.
The end of the pedal pin fits between suitably shaped jaws in the end of the
crank and is there secured by means of a cap, bar or equivalent, which may be
held by screws or other suitable devices. A convenient arrangement is to form the
cap with one closed hole and one open hole so that the one end is permanently
connected while the other can be detached and swung round by merely slackening
the screw, nut, or equivalent which holds it. By this means the pin may be firmly
fixed to the crank in either its open or closed position.
I prefer to place upon the end of the pedal pin a spring or other stop which may
engage when the pedal pin is opened either with the back of the crank or with
the slot therein thus assisting to keep the pedal in its proper position and when
closed it also acts as a stop by bearing against or in the before-mentioned cap so
as to retain the pedal in its folded, position.

I, SEYMOUR BINGHAM, of Wynhaven 75, Rotterdam, in the Kingdom of Holland,
Manufacturer, do hereby declare the nature of this invention, and in what manner
[Price 8d.1

page_text: the same is to be performed, to be particularly described and ascertained in and by
the following statement: -
This invention relates to the attachment of pedal pins, crank handles and the
like, the object being to so connect the pedal pin, handle etc., with the crank that
it can when desired be folded back so as to lie substantially parallel with the
crank.
In carrying out the invention I pivot the pedal pin or equivalent to the crank
preferably by means of ears or a bracket on the outer side of the crank, the pedal
pin being provided with a projecting lug or ear to fit between the ears upon the
crank so that the pin when folded may lie substantially parallel with the crank and
when opened out, at right angles thereto.
The end of the pedal pin fits between suitably shaped jaws in the end of the
crank and is there secured by means of a cap, bar or equivalent, which may be
held by screws or other suitable devices. A convenient arrangement is to form the
cap with one closed hole and one open hole so that the one end is permanently
connected while the other can be detached and swung round by merely slackening
the screw, nut, or equivalent which holds it. Alternatively the cap may
be hinged to one of the crank jaws and secured by a screw pin or catch to the
other. By this cap the pin may be firmly fixed to the crank in either its open or
closed position.
I prefer to place upon the end of the pedal pin a spring or other stop which may
engage when the pedal pin is opened either with the back of the crank or with
the slot therein thus assisting to keep the pedal in its proper position and when
closed it also acts as a stop by bearing against or in the before-mentioned cap so
as to retain the pedal in its folded position.
In the accompanying drawings
Figure 1 is a perspective view showing a pedal constructed in accordance with
this invention in its operative position on the crank.
Figure 2 is a side elevation showing the pedal in its folded position.
Like letters indicate like parts throughout the drawings.
At the end of the crank A are formed jaws A¹, and on the outer side are arranged
lugs A². The pedal pin B is provided with a lug B₁ by means of which it is
pivotted to the lugs A by pins A³ and the end of the pedal pin is squared as at B2
so as to fit between the jaws A¹ of the crank. A bar C is pivotally attached by a
screw D to the end of one of the jaws A' of the crank A, an open hole or slot C¹
being formed in the free end of the bar C to enable it to be engaged with a pin E
upon the other jaw A¹ and there clamped by a nut E on this pin. Upon the end of
the pedal pin is a spring stop B3 which when the pedal is in the operative position
shown in Figure 1, lies in the recess A4 formed on the inner face of the crank, but
when the pedal is in the folded position as shown in Figure 2 the end of the stop
abuts against the bar C and holds the pedal folded well back against the face of the
crank. The pivot screw D upon which the bar C turns is preferably provided with
a milled head to enable it to be slacked down or tightened up when altering the
position of the pedal, or the bar C may be hinged to one of the jaws A¹ and secured
by a screw pin to the other.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. The combination with a crank having jaws such as A¹ of a crank or pedal
pin pivotted upon the crank and shaped to fit the jaws and a detachable cap such
as C substantially as described.
2. The combination with a crank having jaws such as A¹ of a crank or pedal pin
pivotted to the crank shaped to fit between the jaws and having a stop such as B³
substantially as and for the purpose described.
3. The combination with a folding crank or pedal pin of a stop such as B³ for
the purpose described.

a lug such as B₁ jaws such as A³ upon the crank and a shaped end to the pin
substantially as described.
5. The complete crank and folding pin substantially as described or illustrated
in the accompanying drawings.
