Improvements in Pedal Stays or Supports for Velocipedes.
I, ERIK HEDLUND, of Valhallavaegen 39, in the City of Stockholm, in the
Kingdom of Sweden, Engineer, do hereby declare the nature of this invention
to be as follows:-.
This invention relates to improvements in pedal stays of the kind referred to
in the Specification of a prior Patent granted to Edward Petrini, No. 15504 of the
year 1893.
According to my invention I form the support proper of a single piece or frame
which is pivotally secured to a plate adapted to be bolted to the outer end of the
pedal. The stay may be of U-shape, the legs being uppermost when the stay is
in use. The said plate is formed with bearings to receive the inwardly bent ends
of the upper portion of the stay and the said plate is also formed with cam surfaces,
against which the said ends of the frame are adapted by the springiness or
flexibility of the legs of said frame to bear with pressure. The cam surfaces are
so formed that the stay is held thereby in either of its extreme positions until
shifted by the user, therefore when the stay is turned into a position to support the
velocipede it remains in such position instead of tending to close up under the
pedal by the action of a spring as in the device described in the above referred to
specification. When the stay is to be put out of use it is pressed inwardly, a
short distance the aforesaid cam surfaces acting in conjunction with the flexible
frame cause the stay to complete its inward movement and lie horizontally beneath
the pedal.
Suitable means are provided for preventing the stay from turning outwardly
beyond a predetermined position.
COMPLETE SPECIFICATION.
Improvements in Pedal Stays or Supports for Velocipedes.
I, ERIK HEDLUND, of Valhallavägen 39, in the City of Stockholm, in the
Kingdom of Sweden, Engineer, 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 bicycle stays or supports, and has for its object to pro-.
vide a simple and inexpensive device of this class which will remain permanently
connected to the pedals.
According to my invention I form the support proper of a single piece or frame

page_text: which is pivotally secured to the well known plate or plates adapted to be bolted
to the outer end of the pedal. The stay may be of U-shape, the legs being upper-
most when the stay is in use. The said plates are formed with bearings to receive
the inwardly bent ends of the upper portion of the stay and the said plates are
also formed with lugs or cam surfaces against which the said ends of the frame are
adapted by the springiness or flexibility of the legs of said frame to bear with
pressure. The lugs or cam surfaces are so formed that the stay is held thereby in
either of its extreme positions until shifted by the user, therefore when the stay
is turned into a position to support the velocipede it remains in such position.
When the stay is to be put out of use it is pressed inwardly a short distance. The
aforesaid cam surfaces acting in conjunction with the flexible frame cause the
stay to complete its inward movement and lie horizontally beneath the pedal.
Suitable means are provided for preventing the stay from turning outwardly
beyond a predetermined position.
Reference is to be had to the accompanying drawings forming
a part of this
specification, in which similar characters of reference indicate corresponding parts
in all the figures.
Figure 1 is a side elevation of a pedal with my improved stay or support
attached thereto, the support being in an inactive position.
Figure 2 is a similar view with the stay lowered to support the wheel and
Figure 3 is an end elevation of the pedal with the stay lowered.
To the outer end of the pedal is secured a plate d having eyes or bearings c
through which pass the inwardly bent ends b of the stay a. This stay is made in
the form of a U, the legs being uppermost when the stay is in use, and, preferably
consists of a single piece of wire. The side members a of the stey are elastic,
having a tendency to spring apart to the position shown in Figure 3. The hooks b
form pivots about which the stand may be turned from the position shown in
Figure 1 to that shown in Figure 2 and 3. It will be observed that these pivots
extend transversely of the pedal and that in the inactive position (Figure 1) the
stand is entirely out of the way of the rider's foot, whichever side of the pedal is
upward.
In order to hold the stand in the lowered position as well as in the inactive
position, I provide inwardly extending cams or lugs e on the plate d. When the
stay is to be turned into a position to support the velocipede the rider need only
put his foot on the stay so as to press the same outward a short distance until the
side members a have cleared the lugs or cams c. The frame has then been sprung
by the said lugs or cams, and, in returning to its ordinary condition, will act in
conjunction with the cam or lug to complete the movement until it arrives in the
position shown in Fig. 2, when it is, by its upper end resting against the end of
the pedal, prevented from turning further outward. To press the stay out of use
it need only be pressed inward a short distance, when it will act similarly so as
to move inward and lie horizontally as shown in Figure 1.
Of course the lugs might be arranged to engage the outer bends of the side
members a, in which case the said members would have to be made with a tendency
to move toward each other to enable the side members to clear the lugs. This
modification or reversal is so obvious that illustration thereof is deemed
unnecessary.
The plate d may be held by means of the usual screws g securing the pedal
rubbers. The changes to be made for a rat trap or similar pedal are that, instead
of the plate d, two plates, each provided with one lug, are fastened at the sides of
the pedal, as will be well understood by any person skilled in the art to which this
invention appertains.
Having now particularly described and ascertained the nature of this said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
A pedal stay or support for velocipedes, having the upper ends of its side-

page_text: members elastically movable towards and from each other and formed as hooks,
and the plate or plates for attachment to the pedal provided with eyes adapted to
receive said hooks and with projecting lugs or cam surfaces adapted to engage
the said side-members of the stay and normally hold it in either of its extreme
positions, substantially as and for the purpose described.
