Improved Means for use in Fixing the Dust Caps of Cycle Pedals.
We, WOLSELEY SHEEP SHEARING MACHINE COMPANY, LIMITED, of Sydney Works,
Alma Street, in the City of Birmingham, Manufacturers, and HERBERT AUSTIN, of
the same address, Works Manager to the said Company, do hereby declare the
nature of this invention to be as follows:-
:-
The dust caps of cycle pedals have sometimes heretofore been fixed each by a
couple of small screws which have to be entirely removed to allow of the removal
of the caps, and sometimes by screwing them direct upon the bosses of the pedal
end plates. In the former case, however, the small screws are easily dropped and
lost, and owing to their smallness are somewhat difficult to put into place in refix-
ing the caps after removal; and, in the latter case the screw threads inside the caps
and around the bosses of the end plates are necessarily of a very fine pitch, and it
is consequently very difficult to catch the threads in screwing on the caps. It is
especially important that all portions of cycles which require to be occasionally
removed and replaced by a rider whilst upon a journey shall be capable of being
removed and refixed with the utmost facility, as these operations have frequently
to be performed under very adverse circumstances of weather and light; and there
has been an urgent want felt for some better means of fixing dust caps to the
pedals.
Now, according to one part of this invention, the dust caps are fixed by means
of turning pieces or turn buttons each formed with a head of such shape that when
turned into a certain position it allows of the cap being put into place ready for
being fixed, and when the cap has been put into place and the pin then turned a
portion of the head comes in front of a portion of the outer face of the cap.
According to a convenient application of this part of the invention, each turning
piece or turn button is formed with a T-head which is of the width of the stalk
of the pin or slightly wider, but is considerably longer than its width, and is
formed with rounded ends of which the curves appear in outline as seen looking
towards the outer end or face of the head; and oblong holes, of a size and shape
to just allow of the passage of the heads of the turning pieces therethrough, are
formed through flanges or ears or other flat portions of the caps, and these holes are
passed over the heads of the turning-pieces in putting the caps in place, and the
turning-pieces are then turned to bring the projecting ends of the heads in front
of the metal of the portions of the caps through which the holes are formed. The
pins are, of course, swivelled to the end plates of the pedals, or the heads are
swivelled to the pins.
When the pins are swivelled to the end plates so as to be capable of being readily
turned, the heads may, if desired, be formed as simple sideway projections from the
stalks, or they may be formed round with a portion of one side cut away; and,
in lieu of forming holes through portions of the caps to pass over the heads of the
pins, the caps may be formed so that when the pins are turned into a certain posi-
tion they will be clear of the edges of the caps and allow the caps to be put into
place, and when the caps have been put into place the pins may be turned so as

page_text: to bring projecting portions of their heads over the edges of the caps and thus
secure them in position.
According to a further part of this invention the dust caps are fixed by means
of the small screws frequently heretofore employed, but in a manner which avoids
the need for the removal of the screws to allow of the removal of the caps and
this avoids the inconvenience above described as resulting from the use of such
screws. This is effected by forming the holes in the dust cap through which the
screws pass each with a narrow portion to receive the shank of the screw and with
an enlarged portion at one end of such narrow portion which will allow of the
passage of the head of the screw therethrough, and for the purpose of removing
the dust cap the screws are simply slackened and the cap is then turned slightly
axially so as to bring the enlarged portions of the holes opposite to the heads of
the screws.
The cap may then be drawn off over the heads of the screws.

Improved Means for use in Fixing the Dust Caps of Cycle Pedals.
We, WOLSELEY SHDEEP SHEARING MACHINE COMPANY, LIMITED, of Sydney Works,
Alma Street, in the City of Birmingham, Manufacturers, and HERBERT AUSTIN, of
the same address, Works Manager to the said Company, 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 dust caps of cycle pedals have sometimes heretofore been fixed each by a
couple of small screws which have to be entirely removed to allow of the removal
of the caps, and sometimes by screwing them direct upon the bosses of the pedal
end plates. In the former case, however, the small screws are easily dropped and
lost, and owing to their smallness are somewhat difficult to put into place in refix-
ing the caps after removal; and, in the latter case, the screw threads inside the caps
and around the bosses of the end plates are necessarily of a very fine pitch, and it
is consequently very difficult to catch the threads in screwing on the caps.
especially important that all portions of cycles which require to be occasionally
removed and replaced by a rider whilst upon a journey shall be capable of being
removed and refixed with the utmost facility, as these operations have frequently
to be performed under very adverse circumstances of weather and light; and there
has been an urgent want felt for some better means of fixing dust caps to the
pedals.
It is
Now, according to one. part of this invention, the dust caps are fixed by means
of turning pieces or turn buttons each formed with a head of such shape that when
turned into a certain position it allows of the cap being put into place ready for
being fixed, and when the cap has been put into place and the pin then turned a
portion of the head comes in front of a portion of the outer face of the cap. The
turning pieces are, preferably, swivelled to the end plates of the pedals; but the
shanks may be rigidly fixed to the end plates, and the heads be swivelled to
the shanks.
r
A convenient application of this part of the invention is illustrated by Figures 1
and 2 of the drawings herewith, of which Figure 1 is an outer end elevation of
a pedal with the dust cap fixed in place, and Figure 2 a section taken on line
of Figure 1, sufficient only of the pedal being shewn to clearly illustrate the inven-
tion. The dust cap at the inner end of the pedal may, of course, be correspond-
ingly fixed.

page_text: Each turning piece or tum button a is formed with a T-head b and a shank or
stalk c, and is swivelled to an end plate A of the pedal in a manner which admits
of its being turned, and this is accomplished by forming the end of the stalk of a
reduced diameter and then passing the reduced portion of the stalk through a
hole formed through the plate until the shoulder formed by reducing the diameter
of the end of the stalk comes against the outer face of the plate, and riveting over
the end of the stalk, as clearly shewn by Figure 2. The head 6 of each turning
piece is of the width of the stalk or slightly wider, but is considerably longer than
its width, and is preferably formed with rounded ends, as shewn by Figure 1.
Oblong holes d, of a size and shape which will just allow of the passage of the
heads of the turning pieces therethrough, are formed through flanges or ears 6 of
the cap B, and these holes are passed over the heads b in putting the cap in place,
and the turning pieces then turned a quarter turn to bring the projecting ends of
the heads in front of the flanges or ears 6 of the cap. In lieu of forming the
pins with T-heads as above described, the heads of the pins may, if desired, be
formed as simple sideway projections from the stalks, in which case they may be
of round or any other shape in front elevation, the holes through the ears of the
caps corresponding, of course, to the shape of the heads.
A modification of this part of the invention is illustrated by Figure 3, which is
a corresponding view to Figure 1. In this modification the cap B is formed with
a flange f, and the pins g, which are swivelled to the pedal end plate A similarly
as are the pins a, are formed with sideway projecting heads (two examples of
which are shewn) which when in the position shewn by broken lines are clear of
the flange of the cap and will therefore allow the cap to be put into place or
removed, but which when the cap has been put into place may be turned into the
position shewn by full lines to bring them over the flange and thus secure the
cap in place.
According to a further part of this invention, the dust caps are fixed by means
of the small screws frequently heretofore employed, but in a manner which avoids
the need for the removal of the screws to allow of the removal of the caps, and
thus avoids the inconveniences above described as resulting from the use of such
screws.
A convenient application of this part of the invention is illustrated by Figure 4
of the drawings herewith, which is a view correspuding to Figure 1. Holes are
formed through the ears of the dust cap B, through which the screws h pass. Each
hole is formed with a narrow part i to receive the shank of the screw and with an
enlarged portion at one end of such narrow portion, which will just allow of
the easy passage of the head of the screw therethrough; and for the purpose of
removing the dust cap the screws are simply slackened and the cap is then turned
axially to bring the enlarged portions of the holes opposite to the heads of the
screws, and the cap may then be drawn off over the heads of the screws.
A modification of this part of the invention is illustrated by Figure 5 of the
drawings herewith, which is also a view corresponding to Figure 1. In this
modification, the screws are similar to those shewn by Figure 4, but in lieu of
forming ears upon the dust cap with holes therethrough, the cap is formed with
ears having, respectively, an upward and downward notch in the edges thereof.
The cap is secured in place by placing it against the pedal end plate with its ears
clear of the heads of the screws, and then. turning it to bring the sides of the
notches behind the heads of the screws.
While it is much preferred to employ screws in the arrangements described with
reference to Figures 4 and 5, headed studs may be substituted therefor.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
1. Fixing a dust cap of a cycle pedal in place, by means of studs which are
irremovably fixed to the end plate of the pedal and which are provided with heads

page_text: which extend from the axes of the studs further in one or more directions than
in another or other directions and are capable of being moved into positions
which allow the dust cap to be put in place and then moved to bring portions in
front of portions of the cap, substantially as described.
2. Means for use in fixing a dust cap of a cycle pedal, which comprise headed
screws or studs which are connected to the end plate of the pedal, and parts
formed with the dust cap which allow the cap to be placed against the end plate
notwithstanding such screws or studs, but which may, by turning the cap be
brought behind the heads of the screws or studs, substantially as described.
3. The several ways of fixing the dust caps to cycle pedals, as shewn by the
drawings herewith, and described with reference thereto.
