Improved Means for Protecting the Treadles, Gear, and Gear Case of
Bicycles.
I, HERBERT GEORGE PARRY OKEDEN, of 6 Rue de Joncker, in the City of Brussels
in the Kingdom of Belgium, gentleman, 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.
This invention relates to means for protecting the treadles, gear and gear case
of bicycles and has for its object the construction and arrangement of such means
in a simple, light, and portable form but at the same time being capable of
acting as efficient protection against damage from ordinary risks that occur
when the bicycle is standing or being conveyed by a carriage or vehicle. Further
the arrangement is such that the attachment to the machine of the device or
devices is such that the wheels can be used in the ordinary manner for moving
the machine from place to place. I am aware that devices have been used for
protecting bicycles during transit by rail or otherwise, but such devices have
been of the nature of an enveloping crate, consequently the wheels cannot be
used as a means of transport.

My invention consists of detachably attached dises or plates attached to the
frame by removable stays so as to protect the path of the pedals and at the same
time allow of their movement, and also in combination therewith of a diaphragın
protector for the chain gear or gear case containing the same, means being
provided for the ready attachment and steady fixture of the protecting devices
to the framework of the machine. The protecting devices may be made of any
suitable substance or substances which will readily resist damage by knocks or
grazing such for example as plaited basket work.
In order that my invention may be the better understood I will now proceed
to describe the same in relation to the accompanying drawings hereunto annexed
reférence being had to the letters and figures marked thereon. Like letters
refer to like parts in the various figures.
Figure 1, is a side elevation of a bicycle with my protectors attached.
Figure 2, is a sectional end elevation on the line X Y Figure 1.
Figure 3 is a detail. view of one of the crank protecting discs.
Figure 4 is a detail view of the chain gear or gear case protector.
Figure 5 is a detail view of a supporting distance-piece.
Figure 6 is a detail view of the lower hooked stay of the protecting dises.
Figure 7 contains a plan and elevation of one of the stays for supporting the
protecting dises on the frame.

To carry my invention into effect, I detachably attach the two discs or plates A. A
(Figs 1, 2, and 3) to the frame B B (Figs 1 and 2) of the machine, by means of
the stays C C (Figs 1, 2 and 7) each of which, at its central part is adapted to
detachably embrace one of the members of the frame B, by means of the clamping
piece D, (Fig 7) and the two thumb screws E E (Fig 7).

page_text: The protecting discs or plates A A are detachably attached to the ends of the
stays CC by means of the clamping pieces F (Figs 1, 2, and 7) which are
pivotally attached to the ends of the stays C C and are capable of rotating about
the ends of the stays as the axis thus making it possible to, fit without strain a
given pair of protecting discs and stays to any member of a number of machines,
of which the angles formed by the members of the frame, to which the stays
are detachably attached, vary considerably.
In addition to the stays C C, which attach the discs A. A to the framework of
the machine, the discs are further kept in position and their protecting power
and rigidity increased by means of the hooked stay G (Figures 2 and 6) and
eye H (Figures 2 and 3) which are respectively attached to one or other of the
two discs.
Further in order that the protecting discs may have in addition to their
peripheral support, a central support which shall not interfere with the free
movement of the pedals and pedal-crank and which shall supply additional
protecting power to the discs, I detachably attach, to each of the protecting
discs, an adjustable supporting distance-piece I (Figures 2 and 5) which is
made adjustable lengthwise by means of a telescopic joint, which allows the
apex of the central sliding core J, (Figures 2 and 5) of the said distance-piece
to be placed in the centre-pop of the axle of the machine and the resultant length
of the distance-piece to be adjusted and the core finally clamped by the thumb-
screw K (Figure 5) so that the discs are supported, and consequently strengthened,
at their centre.
The adjustable distance pieces are attached to the protecting discs by means
of plates L (Figures 1 and 3) which are screwed to the discs, each distance piece
itself being attached to one of the plates by means of a pivot R (Figure 5) which
allows the apex of the core of the distance-piece to be readily placed in the
centre-pop of the axle, without straining the distance-piece or disc.
To protect the chain gear or gear case M (Figures 1 and 2), I detachably
attach, to the framework of the machine, the diaphragm protector N (Figures 1, 2,
and 4), which is of such a shape as to efficiently cover the chain gear or gear
case, so that at the same time the crank and pedals can be revolved. The attach-
ment can be effected by means of straps O (Figure 1) which pass through holes !',
(Figure 4) in the said protector and surround the members Q (Figure 1) of the
framework of the machine.
In order that the protecting device may be capable of close packing the pro-
tecting discs are connected with the stays by means of the clamping hinges F
(Figure 7) which permit the discs to be detached from the stays where necessary
to allow the discs to be placed side by side together and also permit the stays
to be folded down upon the discs, together with the hooked stay and central
supports, which are also hinged to the discs and can be folded upon them.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
1st. Improved means for protecting the treadles, gear, and gear case of bicycles
consisting of two discs or diaphragms detachably supported upon the frame of
the machine by detachably attached stays, and adjustable central supports or
struts adapted to bear on the centre of the axle, the whole being arranged to
permit of the rotation of the wheel and the gearing, substantially as described.
2nd. In such a protecting device as claimed in claim 1, the arrangement of the
stays and supports with hinged connection to the discs or diaphragms to allow
of them being folded down thereon for the purpose of close packing substantially
as described.
3rd. A protecting device as claimed in claim 1 in combination with a separate
protecting diaphragm for the gear or gear case and means for detachably attaching
the same to the frame of the machine, substantially as described.

page_text: 4th. The arrangement and construction of protecting devices for the treadles,
gear, and gear cases of bicycles, substantially as described and illustrated in the
accompanying drawings.
