PROVISIONAL SPECIFICATION.
Improvements in Pedals for Velocipedes.
PHILIP LOUIS RENOUF of Stoke near Coventry in the County of Warwick
Engineer do hereby declare the nature of this invention to be as follows:-
The object of this invention is to produce the main part of the body of a
velocipede pedal out of sheet metal. For this purpose I sometimes make the
whole pedal out of one single piece of sheet metal, by pressing two boles or
recesses to receive the bearings, then pressing out the sides and the centre (with
the teeth ready shaped for the "rat-trap" variety). The bearing sides are then
turned up at a right angle to the other sides which thereby form the "stretchers."
These stretchers may be used to form a bed for the rubber or may form rat-traps.
Sometimes the stretchers are mounted between two ordinary bearing plates in a
horizontal instead of a vertical position thus affording greater rigidity sideways.
Sometimes the body is formed by raising part of a metal sheet in form of a box or
cup the sides will receive the bearings and the raised portion is partially or
totally removed..

COMPLETE SPECIFICATION.
Improvements in Pedals for Velocipedes.
I, PHILIP LOUIS RENOUF, of Stoke, near Coventry in the County of Warwick,
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 :-
The object of this invention is to produce the main part of the body of a
velocipede pedal out of sheet metal. For this purpose I sometimes make the
whole pedal body of one single piece of sheet metal.
Referring to the drawings
Fig. 1 shews a sheet metal blank cut or pressed in to a quadrilateral shape, two
sides being serrated and two sides being pierced and recessed, or pierced only.
"
Fig. 2 shews this same plate bent up so that the pierced sides A and B take
the place of the ordinary side plates of a pedal, and the serrated edges of the
sides C and D, which act as "stretchers are turned up, each tooth being in an
opposite direction to the adjacent one, so that four rows of teeth or "rat traps
formed.
Fig. 3 shews an end elevation.
"
are
Where it is desired to use rubber, rubbers E, F are laid on the "stretchers" C, D
which form a base for the said rubbers and they are kept in place by pins or bolts
passed through the slots h. The whole of the rubber will then form a good
steady cushioning support for the foot of the rider, whereas on ordinary pedals the
rubber is only partly supported by the stretcher bar. Sometimes the sides A, B
receive hardened bushes which form the bearings, but sometimes the bearings
themselves are pressed out of these plates. Sometimes I use the ordinary separate
side plates, but connect them with a pair of stretchers of the same shape as the
sides C and D, and having four rows of teeth, and joined to the side plates
horizontally instead of vertically as is usually the case; by this means greater
rigidity is obtained, as well as a better support for the rubber where such is
employed.

page_text: I may also produce the pedal body by pressing or raising a piece of sheet metal
in to the form of a round or of a square box, and then punching away the centre as
shewn at Fig. 4; thus all four sides will be vertical as is the case with the ordinary
pedal, but all rivetting up or screwing up will be dispensed with. Two holes are
provided in the ends opposite each other for the insertion of the pedal spindle in
the ordinary manner.
. 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
Firstly Making the whole four sides of a pedal body out of a single piece of
sheet metal without a rivetted, brazed, lapped or screwed joint of any kind, in the
.manner substantially as described.
Secondly-Rat-trap pedal stretchers C, D with several rows of teeth and
joined to the side plates horizontally substantially as described.
Thirdly-The pedal made out of sheet metal illustrated in Figs. 1, 2 and 3,
substantially as described.
Fourthly Mounting and supporting the rubbers of pedals on horizontal sheet
metal stretchers in the manner and for the purpose described.
