PROVISIONAL SPECIFICATION.
Improvements in or applicable to Pedals of Velocipedes.
I EDWARD TILSTON of 6 Industrial Street, Chorlton-on-Medlock, Manchester,
Mechanical Draughtsman, do hereby declare the nature of this invention to be as
follows:-
My said invention relates to improvements in or applicable to pedals for
velocipedes.
In pedals having indiarubber or other similar elastic parts for the foot to rest on
as heretofore constructed it has been usual to form such parts as bars secured by
mounting them on a central spindle ordinarily square in order to prevent the
rotation of the rubber bar by the pressure of the foot.
According to my said invention the elastic parts are held between lateral supports
instead of on a central spindle.
The elastic parts may consist of solid bars or blocks of indiarubber shaped so
as to engage with the lateral supports or they may be hollow tubes compressed
laterally by the lateral supports or they may be formed from blocks or bars having
holes or cavities therein. Such holes or cavities may serve as air spaces filled with
air at the normal atmospheric pressure or they may be filled with air at a higher
pressure as in the case of pneumatic tyres. In some cases such cavities may be
filled with rubber sponge or the like light and elastic material.
In some cases I form the elastic support by doubling or bending over one or
more bands of elastic material and securing their edges between the lateral
supports. The lateral supports between which the elastic parts are held may be
plates or bars held in position in the pedal by suitable meaus.

COMPLETE SPECIFICATION.
Improvements in or applicable to Pedals of Velocipedes.
I EDWARD TILSTON of 6 Industrial Street, Chorlton-on-Medlock, Manchester
Mechanical Draughtsman, 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 and accompanying drawings:-
My said invention relates to improvements in pedals for velocipedes and has for
its object an improved method of securing the rubbers or pads on which the feet
rest and which are intended to minimise vibration.
In the accompanying drawings
Figure 1 is a plan partly in cross section.
Figure 2 is a section through -y of Figure 1.
Figure 3 is a side elevation.
Figures 4, 5, and 6 represent modifications to be hereinafter referred to.
In the drawings a is the spindle on which the side plates 6 of the pedal are
mounted in the usual manner.
In pedals having indiarubber or other similar vibration destroying pads for the
foot to rest on it has been usual heretofore to secure such pads when in the form of
bars by bars bolts or pins passing through the pad.
Price 8d1

page_text: According to my said invention the pads are secured by lateral binding pieces
taking into lateral recesses or depressions in the pads.
When using solid pads (as distinguished from pads formed with air spaces) I use
the construction shown in Figures 1 and 2 in which c are the pads having lateral
. recesses in which engage hollow tubes d secured by rivetting or by screws to the
side plates b.
When using hollow pads I take a tube as g Figure 5 having thick walls and
compress the same between the lateral supports d as shown in Figure 6. Air spaces
are thus formed inside the pad above and below the lateral supports d which may
be filled with rubber sponge or the like light and elastic material.
A modification is shown in Figure 4 in which I use dished side plates d¹ to grip
the rubbers c¹ which in this case may be divided as shown so that either half of the
rubber may be readily replaced.
When the pads are secured between lateral supports as hereinbefore described
they are more effective as vibration destroying agents than when secured by pins
bolts or other fastening pieces passing through the pads. A less weight of rubber
may be used and the pedal as a whole is considerably lightened.
In lieu of indiarubber, combinations of textile materials and rubber, leather
or other similar elastic or vibration destroying materials may be used for the pads.
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 velocipede pedal the combination of a pad having lateral recesses or
depressions with lateral supports engaging therewith as set forth and shown.
2. In a velccipede pedal'a pad formed of a hollow tube g pinched and held in
position between lateral supports d as set forth and shown in Figures 5 and 6.
3. In a velocipede pedal the combination of a divided pad with lateral
supports d' gripping and holding the pad in position as set forth and shown in
Figure 4.
