PROVISIONAL SPECIFICATION.
An Improved Pedal for Cycles.
I THOMAS GROVES Machinist Psycho Villas Starley Road Coventry in the
County of Warwickshire do hereby declare the nature of this invention to be as
follows:-
My invention consists of a pedal which can be used as what is known as a rat
trap pedal or with the same or different metal side plates and the addition of india
rubber pads and the same metal end or ball plates as a rubber pedal.
At each extremity of the end or ball plate (a recess in which carries the balls
forming the bearings) I cut a screw thread on a round projection which is forged
on the end plate for that purpose these projections pass through holes in the side
plates up to a shoulder formed at the base or root of the thread on the end plate a
nut or nuts is used to hold the side plate or plates in position which it or they
does by holding the side plate tightly against the shoulder on the end plate the
pedal is then fitted with the usual axle pin cones balls and nuts and is then

COMPLETE SPECIFICATION.
An Improved Pedal for Cycles.
I, THOMAS GROVES, Machinist, Psycho Villas, Starley Road, Coventry, in
the County of Warwick, 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 consists of a pedal which can be used for what is known as a rat
trap pedal and an india rubber pedal with different metal side plates, or the same
metal side plates with the addition of india rubber pads, the metal and rubber side
plates being interchangeable and capable of being attached to the same metal end
or ball plates.
In the accompanying sheet of explanatory drawings―
Figure 1 is a plan of my improved form of rat trap pedal with curved plates.
Figure 2 is a plan of my rat trap pedal with straight plates.
Figure 3 is a front elevation of same.
Figure 4 is an end elevation.
Figure 5 is a plan of my improved india-rubber pedal and
Figure 6 is an elevation of the same.
Figure 7 is a sectional plan of my improved rubber connection which I prefer to
employ.
I provide a recess in the end plates A A¹ which carry the balls forming the
bearings B.
I cut a screw thread a on a round projection which is forged on the end plates,
and these projections pass through holes in the side plates C, C₁ up to a shoulder
formed at the base or root of the thread on the end plates; a nut or nuts D, D¹ is
used to hold the side plate or plates in position by screwing the side plate tightly
against the shoulder on the end plates.
I fit the pedal with the usual axle pin E and the ordinary cones, balls and nuts,
and is then complete for attachment to a cycle in the well known manner.
I prefer to construct my interchangeable rubber pedals as shown in Figures 5, 6
ED 037

page_text: and 7 in which F, F is the block or pad of india rubber or like material having a
barrel or case of metal formed by the strip or plate G, G' being carried round so
as to enclose the pad or block; the ends of this case or binding strip being
brought together by rivets or screws, or I sometimes hold them by the pins a and
nuts which bind them to the plates A, A'. I employ one or more rivets on the
pins or screws K to give additional security to the combination.
I do not limit the application of my improved interchangeable rubber pads to
any particular form of rubber block, but I mount any desired shape of block to
my ball or end plate pins a, a in the manner hereinbefore described when
employing my improved form of block F.
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. The construction of cycle and like pedals having ball or end plates arranged
so as to form either a rubber type pedal or a rat trap type pedal, substantially as
herein before described.
2. The construction of side plates for rat trap type cycle and like pedals having
holes at their ends permitting of their attachment to the ball or end plates, sub-
stantially as herein before described and as illustrated in Figures 1, 2, 3 and 4 of
the accompanying drawings.
3. The construction of rubber type cycle and like pedals in which the rubber
pads or blocks are secured to the end or ball plates by means of pins or screws
such as a passing through the ends such as y substantially as hereinbefore described
and as illustrated in Figures 5, 6 and 7 of the accompanying drawings.
Dated this 28th day of November 1892.
