Certain Improvements in Bicycles, Tricycles, and other Velocipedes.
We, WILLIAM BENJAMIN TEALE, of 36, Lancaster Street, in the City of
Birmingham, Manager of the Cycle Department of Perry & Co., Limited, and
FRED OLDFIELD, of 36, Lancaster Street, aforesaid, Works Manager, do hereby
declare the nature of this invention to be as follows:--
The first part of this invention of improvements in bicycles tricycles and other
velocipedes consists of the following improved method of securing the pedal pin to
the crank so as to dispense with the usual projecting nut on the face of the crank
and thus enable the treads of the pedals to be arranged nearer together. In
carrying out this part of this invention the outer end of each crank is tapped as
usual to receive the pedal pin which is screwed therein but the pedal pin instead of
projecting beyond the crank and being fixed by a nut, is cut off about flush with
the face of the crank and secured by the eye of the crank being slit longitudinally
in a plane at right angles to the axis of the pedal pin and by one or more screws
in the crank which are screwed up so as to close or partly close this slit when the
pedal pin is screwed into the crank so that this partial closing of the slit will
effectually lock the pedal pin on to the crank.
The second part of this invention consists of the hereindescribed improved
method of securing the chain wheel to the crank axle so as to occupy less space on
the crank axle and enable the treads of the cranks to be brought nearer together
and so as to enable the chain wheel to be readily removed and replaced by a larger
or by a smaller chain wheel so as to alter the gearing of the machine. In carrying
out this second part of this invention the chain wheel which is bored as usual fits
on a collar formed on the crank axle which is slightly larger than the end of the
crank axle on which the crank fits. The said chain wheel is located between
the boss of the crank and a shoulder formed on the crank axle. In order to fix the
chain wheel on the collar of the crank axle we drill one or more holes parallel with
the axis of the crank axle half in the collar of the axle and half in the boss of the
chain wheel and in this hole or in each of these holes we fit a steel or other peg
which is or are fixed to the face of the crank or to a washer which is threaded on
to the crank axle, or the said pin or pins may be separated from the washer and
from the crank. To remove the chain wheel the crank has first to be removed
bringing with it the peg or pegs (when they are fixed to the crank) or allowing of
the washer with its pegs, or the separate pegs, to be removed. The chain wheel
can then be withdrawn from the axle.
The third part of this invention consists of the following improved construction of
brake for acting on pneumatic tyres. In carrying out this part of our invention
we make a bearing block of wood vulcanised indiarubber or other suitable substance
which is arched or somewhat V shaped underneath and which is carried by a metal
holder of the construction hereinafter described which metal holder is fixed to the
bottom of the vertical pressure tube or rod which is acted upon by the brake lever
at the top. The said metal holder is in the form of a cross bar having two or more
outwardly projecting side ears at each end corresponding with the sides of the
bearing block which latter are shaped to take two screws or other pins which are
passed through the ears and through the sides of the bearing block about parallel
with the cross bar so as to secure the bearing block to the holder. By first
removing these pins the bearing block can be removed from the holder and a new
bearing block inserted therein. The sides of the bearing block are well rounded off
so as to offer a rounded surface to the tyre. When the bearing block is in use these

page_text: rounded surfaces act upon the periphery of the tyre at a short distance apart and
forces the tyre upwardly somewhat into the arched or V shaped top of the block
thus giving the necessary friction to retard the wheel.

COMPLETE SPECIFICATION.
Certain Improvements in Bicycles, Tricycles, and other Velocipedes.
We, WILLIAM BENJAMIN TEALE, of 36, Lancaster Street, in the City of
Birmingham, Manager of the Cycle Department of Perry & Co., Limited, and
FRED OLDFIELD, of 36, Lancaster Street, aforesaid, Works Manager, 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, reference being had to the figures and letters of reference on the
accompanying illustrative sheet of drawings :

The first part of this invention of improvements in bicycles tricycles and other
velocipedes consists of the following improved method of securing the pedal pin to
the crank so as to dispense with the usual projecting nut on the face of the crank
and thus enable the treads of the two pedals to be arranged nearer together. This
part of our said invention is illustrated by Figs. 1 and 2 of which Fig. 1 is a side
view of a velocipede crank with the pedal pin secured thereto in accordance with
this part of our said invention and Fig. 2 is a sectional side elevation of the portions
of the said crank and pedal pin which are fixed together.
A is the crank and B is the pedal pin. In carrying out this part of this invention
the outer end a¹ of each crank A is tapped as usual to receive the pedal pin B
which is screwed therein but the screwed end of the pedal pin B instead of
projecting beyond the crank and being fixed by a nut is cut off about flush with the
ince of the crank and secured by the eye a' of the crank being slit longitudinally
at a³ in a plane at right angles to the axis of the pedal pin B and by one or more
(preferably two) screws c¹³ in the eye of the crank which are screwed up so as to
close or partly close this slit a when the pedal pin B is screwed into the crank so
that this partial closing of the slit a³ will effectually lock the pedal pin B in the
eye a' of the crank A.
The second part of this invention consists of the hereindescribed improved
method of securing the chain wheel to the crank axle so as to occupy less space on
the crank axle and enable the treads of the pedals to be brought nearer together
and to enable the chain wheel to be readily removed and replaced by a larger or
by a smaller chain wheel so as to alter the gearing of the machine. This second
part of our said invention is illustrated by Figs. 3, 4, 5 and 6 in all of which the
same letters of reference indicate the same or corresponding parts. Fig. 3 is a
sectional side elevation of a portion of the crank axle and crank with the chain
wheel fixed on the crank axle in accordance with this invention; Fig. 4 shews the
wheel hub and the crank axle in cross section; Fig. 5 shews the parts separately
and Fig. 6 shews a portion of the crank which fits on the crank axle and which is
provided with two projecting side pins in accordance with a modified arrangement
of this second part of our invention.
A is the crank, D is the crank axle and E is the chain wheel. In carrying out
this second part of our invention the chain wheel E which is bored as usual fits on
a collar d' formed on the crank axle D and which is slightly larger than the end d²
of the crank axle on which the crank A fits. The chain wheel E is located
between the boss a³ of the crank and a shoulder formed on the crank axle. In
order to fix the chain wheel E on the collar d¹ of the crank axle D we drill one or
more (preferably two) holes f¹ f parallel with the axis of the crank axle half in

page_text: the collar d' of the axle and half in the boss e' of the chain wheel and in each of
these holes (or in this hole when there is only one of them) we fit a steel or other
peg in this case two in number marked respectively g² 9³ which are fixed to a
washer G which is threaded on to the smaller part of the crank axle and fits
between the face of the crank A and the face of the boss e¹ of the chain wheel.
To remove the chain wheel E the crank A has first to be removed thus allowing of
the washer G with its pegs to be removed and then the chain wheel E can be
withdrawn from the axle. Thus the chain wheel E can readily be removed and
replaced by a smaller or larger chain wheel. Instead of the pegs such as g' g (or
a single peg when only one is used) being fixed to the washer G these pegs or the
single peg may as shewn by Fig. 6 be fixed to the face of the boss a' of the crank
so as to engage in the holes f1 f and secure the wheel on the crank axle.
Or instead of the said peg or pegs being fixed to the crank axle A' or to the
washer G the said peg or pegs may be entirely separate from the washer or from
the crank.
The third part of this invention consists of the following improved construction
of brake for acting on pneumatic tyres. This part of our said invention is
illustrated by Figs. 7, 8 and 9 of which Fig. 7 is a general view of the said brake
constructed according to this part of our invention; Fig. 8 shews the metal holder
part of the said brake separately and Fig. 9 is a separate view of the bearing block
of the said brake.
In carrying out this part of our invention we make a bearing block H of wood
vulcanized indiarubber or other suitable substance which as shewn is or may be
somewhat shaped underneath and which is carried by a metal holder I of the
construction hereinafter described which metal holder is by its boss fixed to the
bottom of the vertical pressure tube or rod J which is acted upon by the brake
lever at the top. The said metal holder I is in the form of a cross bar ♬ having
two or more outwardly projecting side ears in this case six in number marked
respectively; three of these side ears namely being on one side
of the cross bar and corresponding with one side of the bearing block H and
the other three side ears being on the other side of the cross bar and corre
sponding with the other side of the hearing block H. The bearing block H fits
between the side ears and is there secured by two screws or other pins which are
passed through the ears and through the sides h¹h of the bearing block H about
parallel with the cross bar so as to secure the bearing block H to the holder. By
first removing these pins k² ² the bearing block H can be removed from the holder 1
and a new bearing block inserted therein. The sides h¹³ of the bearing block are
well rounded off as shewn so as to offer a rounded surface to the tyre. When the
brake above described is in use these rounded sides h³ ³ of the bearing block H
act upon the periphery of the tyre at a short distance apart and force the tyre
upwardly somewhat into the arched or V shaped top h³ of the block thus giving
the necessary friction to retard the wheel.
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 :-
1. A velocipede crank having its pedal pin fixed thereto by the pedal pin being
screwed into the crank in combination with the eye of the crank being slit at right
angles to the axis of the pedal pin and one or more screws which pass through the
slit and close or partly close the slit so as to lock the pedal pin in the crank
substantially as set forth.
2. A velocipede crank having its eye for the pedal pin tapped to receive the
pedal pin the said eye being slit transversely and provided with one or more screws
adapted to close or partly close the slit for the purpose of locking the pedal pin in
the eye of the crank substantially as set forth.
3. The hereindescribed improved means for securing the driving chain wheel on
to a velocipede crank axle so as to allow of the said wheel being readily removed

page_text: and replaced, consisting in fitting the chain wheel on a swell of the crank axle
between a collar d' on the crank axle and the boss of the crank, in combination
with one or more pegs such as g' g' fixed to a washer G or fixed to the face of the
crank, or made separate therefrom, which peg engages or pegs engage in a corre-
sponding hole or holes drilled longitudinally half in the chain wheel and half in the
crank axle all substantially as hereinbefore described and illustrated by Figs. 3, 4,
5 and 6 of the accompanying drawing.
4. The hereindescribed improved construction of brake for pneumatic tyres,
consisting of the combination of the metal holder I and indiarubber or other
suitable bearing block H constructed and combined together in the manner and for
the purpose substantially as hereinbefore described and illustrated by Figs. 7, 8
and 9 of the accompanying drawing.
