Improvements in Cycle Treadles.
We THOMAS WARWICK FREDERICK WARWICK and EDWARD WARWICK,
Bicycle Manufacturers of Alma Street Aston in the County of Warwick do hereby
declare the nature of this invention to be as follows:-
Our invention consists of the improvements in cycle treadles hereinafter set
forth.
We provide two side-checks each of such cheek is formed with a cup-bearing to
receive spherical balls; each end of one of the cheeks is pierced with a
D shaped hole, each end of the other cheek being pierced (by preference) with
round holes.
We next provide a connecting-bar which would be made of the usual tapered
form, the back end of such bar being formed of the usual longitudinal transverse
section suitable to pass through slot of cycle, a threaded pin part projecting
beyond the slot of fork so that a nut passed over the projecting pin part would
secure the connecting-bar to crank.
A hollow would be formed on base-fange of connecting-bar in the usual manner,
to cover the spheericall balls placed in cup of side-check and thus form a ball
bearing for back end of connecting-bar.
The front or small end of connecting-bar would be provided with a screwthread
over which would be passed a lock nut. By the first modification of our invention
we make an essential improvement at the small end of connecting-bar "dispensing
with the usual protruding screwed end and also with the securing nut over such
protruding end.
To secure the side checks on the connecting-bar the required distance appart, we
form the loose top bearing in the following manner.
Our improved loose top-bearing presents the appearance of a very short, flat
headed bolt, the head being of circular plan and the shank being bored up to
within a safe distance of the solid head, the periphery of short shank radiates
outwards, forming a concave periphical hollow under the head, suitable to fit over
the usual spheericall balls: We pass the shank of our improved top bearing
through the pin hole formed in checks and then rotate the threaded small end of
connecting-bar up the screwed hole formed in the shank to receive stand when
both sets of balls are in position in both checks we tighten the lock nut (that is
threaded over small end of connecting-bar) on to the end-face or shank face of our
improved top bearing, thus dispensing with the unsightly nut usually used on the
outside face of side check.
By a second modification of our invention we (in addition to the improved top
bearing) provide two rubbers, the transverse section of which would be a
parallelogram the narrow ends of which would be convex; through the rubber we
pass a square axial-rod in the manner now usual with other pedal-rubbers but our
connections differ from other known connections in the following manner.
We provide a metal clip formed with two right-angular bends, thus producing a
fender shape; the flat face of fender shaped clip is pierced with a square axial
hole, we pass the clip over the protruding end of axial rod, thus covering the end
face of rubber with the flat face of clip, the ends of fender, embracing the two
sides of rubber; we next pass the screwed end of axial rod through the D shaped
hole formed in the end of one of the side cheeks to receive it, and then by
passing a nut over the protruding end of rod, press the inner surface of side
cheek against the face of fender shaped clip, the second rubber would be

page_text: connected to the other D shaped opening in side cheek and the treadle frame
completed, by connecting the other ends of rubber axial-rods to the second side
cheek.
The advantages of this second modification of our invention are, that in adopting
the longitudinal section of rubber blocks we reduce the weight of rubber and by
using the fender shaped clips in the manner set forth we get a large area of end-
bearing surface, "metal against metal" and by means of this end bearing surface
our improved shaped rubbers are supported in position for use.

COMPLETE SPECIFICATION.
Improvements in Cycle Treadles.
We THOMAS WARWICK, FREDERICK WARWICK and EDWARD WARWICK,
Bicycle Manufacturers of Alma Street Aston 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:-
Our invention consists of the improvements in cycle treadles hereinafter set
forth.
We provide two side-cheeks each of such cheeks is formed with a cup-bearing
to receive spherical balls; each end of one of the cheeks is pierced with a
D shaped hole, each end of the other cheek being pierced (by preference) with
round holes.
We next provide a connecting-bar which would be made of the usual tapered
form, the back end of such bar being formed of the usual longitudinal transverse
section suitable to pass through slot of cycle, a threaded pin part projecting beyond
the slot of fork so that a nut passed over the projecting pin part would secure the
connecting-bar to crank.
A hollow would be formed on base flange of connecting-bar in the usual manner,
to cover the spherical balls placed in cup of side cheek and thus form a ball-bearing
for back end of connecting-bar.
The front or small end of connecting-bar would be provided with a screw thread
over which would be passed a lock nut. By the first modification of our invention
we make an essential improvement at the small end of connecting-bar dispensing
with the usual protruding screwed end and also with the securing nut over such
protruding end.
To secure the side cheeks on the connecting-bar the required distance apart, we
form the loose top hearing in the following manner.
Our improved loose top bearing presents the appearance of a very short, flat
headed bolt, the head being of circular plan and the shank being bored up to
within a safe distance of the solid head the periphery of short shank radiates
outwards, forming a concave periphical hollow under the head, suitable to fit over
the usual spherical balls; we pass the shank of our improved top bearing through
the pin hole formed in cheek, and then rotate the threaded small end of connecting-
bar up the screwed hole formed in the shank to receive it and when both sets of
balls are in position in both cheeks we tighten. the back nut (that is threaded
over small end of connecting-bar) on to the end face or shank face of our improved
top bearing, thus dispensing with the unsightly nut usually used on the outside face
of side cheek.
By a second modification of our invention we (in addition to the improved top
bearing) provide two rubbers, the transverse section of which would be a
parallelogram the narrow ends of which would be convex; through the rubber we

page_text: pass a square axial rod in the manner now usual with other pedal-rubbers but our
connections differ from other known connections in the following manner.
We provide a metal clip formed with two right angular bends, thus producing a
fender shape; the flat face of fender shaped clip is pierced with a square axial
hole, we pass the clip over the protruding end of axial rod, thus covering the end
face of rubber with the flat face of clip, the ends of fender, embracing the two
sides of rubber; we next pass the screwed end of axial rod through the D shaped
hole formed in the end of one of the side cheeks to receive it, and then by
passing a nut over the protruding end of rod, press the inner surface of side
cheek against the face of fender shaped clip, the second rubber would be
connected to the other D shaped opening in side cheek and the treadle frame
completed by connecting the other ends of rubber axial-rods to the second side
cheek.
The advantages of this second modification of our invention are, that in adopting
the longitudinal-section of rubber blocks we reduce the weight of rubber and by
using the fender shaped clips in the manner set forth we get a large area of
end bearing surface metal against metal and by means of this end bearing surface
our improved shaped rubbers are supported in position for use.
We will now proceed to describe the nature of our invention and the manner in
which the same is carried into effect reference being had to the accompanying
drawings.

In carrying out our invention we provide two side cheeks a and b. We next
provide a connecting-bar e on which would be formed the usual hollow to cover the
spherical balls d the front end of connecting-bar being provided with a screw
thread over which would be passed the lock nut e.
We next provide a top-bearing which consists of the short barrel with convex
shank head as represented in section at Figure 1, the shank radiating outwards
forming a concave periphical hollow suitable to fit over the usual spherical balls g,
the internally threaded small end of top bearing being screwed over the threaded
end of connecting-bar until both sets of spherical balls d and g are adjusted to an
easy bearing, the lock nut e is then tightened against the face h of top bearing
thus forming an efficient ball bearing pedal without the unsightly nut that usually
projects from the end j of pedal connecting-bars.
By the second modification of our invention we provide two pairs of rubbers
connected to two pairs of fender shaped clips, the rubber is shewn in plan and in
section at Figures 8 and 11 and the fender shaped clips are shewn in detail at
Figures 6, 7, 10, and 14, the fender clips are formed by preference out of sheet
steel stamped into the shapes represented on drawings and pierced with the

page_text: openings so as to produce a fender of maximum rigidity and minimum weight,
the two fenders are connected together by means of the axial rod distance-pieces m
the distance-pieces are pierced with holes n, rivets o are passed through the fenders
and through the distance pieces, thus securing the distance pieces to the
fenders; a convex faced rubber block is then placed in the top fender
P and a
second block placed in the bottom fender g; an end plate (through which is
pierced a central D shaped hole and two rod holes) is then passed over the
projecting D shaped axial rod and a second plate is then passed over the other
axial rod u.
The two pairs of fender clips and rubbers are connected to the side cheeks as
represented at Figures 1, 2, and 5, the axial rods are passed through the D-shaped
holes formed in side cheeks such checks being secured in position by means of the
nuts a a and the rubbers being secured in the fender clips by means of the
connecting pins and their nuts cc the lower pair of fender clips d d
being secured to the side cheeks a and b in a similar manner to the upper pair
of clips.
I do not claim the side cheeks as represented at Figures 12 and 13 to be
of novel shape but I utilize such standard pattern side checks (or other suitable
and equivalent side cheeks) with the novel parts and connections hereinbefore
described.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:
The making of a cycle treadle by the utilization of side-checks, end-plates,
fender-clips, rubbers, axial pins, connecting bar, spherical balls and their bearings
together with other connections as illustrated and described.
