PROVISIONAL SPECIFICATION.
Improvements in Mud Guards for Cycles.
I, ROBERT ARTHUR DAY, of Ellerslie, Harrogate, in the West Riding of
Yorkshire, do hereby declare the nature of this invention to be as follows:-
My invention relates to an improved construction of mud-guard for cycles or
velocipedes, and it consists essentially in making the guard independent of the frame
adapted to carry it, so that the said guard can be readily detached from the said
frame when not required, either leaving the frame attached to the machine, or
removing it therefrom.
The material which I use for the guard is xylonite of which I take a thin strip
of the necessary width and length to form the guard for the desired wheel. This
material is soft and pliant and yet stiff enough to support and carry its own weight,
and when it is removed from the frame carrying it, it can easily be rolled up when
it occupies a very small space and can be conveniently carried either in the pocket,
or in the tool bag.
The frame which I prefer to use for carrying the guard consists of two narrow
strips of metal lying one over the other and bent to follow the periphery of the
wheel. One end of each of these two strips is fixed to the frame of the machine
in any convenient manner, preferably by a screw so that they can be easily
detached, and the other ends are carried by the usual stay fork mounted on the axle
of the wheel, or on the fork or frame of the machine adjacent thereto, the ends of
the said strips being attached to the crown of this stay fork by a screw, or by any
convenient form of clip. The piece of xylonite forming the guard is slipped in
between these two narrow strips of metal and clamped thereto by two or more
screws which may for convenience be the screws which fix the strips to the fork or
frame of the machine and to the stay fork carrying them.
Another method of carrying the guard is to form a frame with slotted edges into
which the guard can be slid from the free end of it.
Another convenient construction of frame is to take two flat strips and connect
their edges by suitable cross pieces, the strip of xylonite forming the guard being
slid in between the two longitudinal strips and the various cross pieces or strips,
and fixed thereto by one or more screws or clips.
Although I prefer to use xylonite there may be other materials equally suitable
for the guard and therefore I hold myself at liberty to use any other material which
may be found suitable for the purpose.
Thated this 4th day of November 1893.

COMPLETE SPECIFICATION.
Improvements in Mud Guards for Cycles.
I, ROBERT ARTHUR DAY, of Ellerslie, Harrogate, in the West Riding of
Yorkshire, 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 relates to an improved detachable mudguard for cycles or
velocipedes, and it consists of a cover of flexible but self-supporting material such

page_text: one or more bars or strips adapted to lie over the centre of the tyre of the wheel
the guard is intended to cover and of one or more supporting forks or stays, the
object being to obtain a light and easily detachable cover, the supporting frame
of which when left on the machine is not in the way of the rider and has not an
unpresentable appearance.
I attain this end in the manner shown by the accompanying drawings which
illustrate by way of example only-a mudguard for the front or steering wheel
of a cycle.

Figure 9 Sheet No. 1 is a view in perspective of the box adapted to carry the
cover of the guard and when not in use and intended to be fixed by the clip it
carries to any suitable part of the frame of the machine.
Figure 10 Sheet No. 2 is a view in side elevation showing a modification of my
invention, and
Figures 11, 12, 13, 14, 15 and 16 Sheet No. 2 are views--some on an enlarged
scale showing the details of construction of the said modification.
Throughout the views similar parts are marked with like letters of reference.
In one form the frame of the mudguard consists of a single strip of metal A
hent to suit the diameter of the wheel it is intended to cover, and of a light fork B
adapted to be attached to the strip A at or near one end and to be attached to
the axle of the wheel or to the fork carrying it as shown by Figures 1, 2, 3, 4, 5, 6
and 7. The other end of the strip A is provided with an eye a by which it is
attached by means of a screw to the crown of the front fork of the cycle, but it
may be attached thereto in any other convenient manner. Both ends of the
strip A are turned over to form clips D, D, to hold the cover C and it is also
provided with one or more studs a¹ to keep the said cover in place. The cover C
of the guard consists of a strip of any suitable flexible but self-supporting water-
proof material such as xylonite or celluloid and it has a series of small holes e in
it to engage with the studs al on the strip A of the frame. As an extra support
for the cover C the crown of the supporting fork B may be shaped to form or
carry either directly or indirectly clips D', D', to embrace it as shown by
Figures 6 and 7, or a cross strip or bar B' having clips D', D', at its ends may
be attached to the crown of the fork B as shown by Figures 4 and 5. This cross
strip or bar B1 may be mounted on the crown of the fork B so as to swivel and lie
over the strip A when not in use.
The supporting frame is intended to remain on the machine, but the cover is
only intended to be used when a guard is required, and when not in use it is rolled
up and carried either in a small cylindrical box X adapted to be attached to any
convenient part of the frame of the velocipede by means of the spring clip
its equivalent, or in the riders pocket or tool bag.
or
To attach the cover to the frame of the guard it is simply sprung into the
clips D, D, and the clips D', D', if such are employed and the holes c in it are
engaged with the studs a¹ on the strip A to prevent its lateral movement.
In order that the end of the guard may be brought as near to the ground as

page_text: possible, the lower end of the strip A is made of a piece or a nexible strip of
steel A' as shown by Figure 8 and so that it will yield in case it comes into contact
with any obstacle on the ground.
A guard for the rear or driving wheel or wheels of a velocipede is constructed
in a similar manner to that herein before described, its length being such that it
will cover as much of the said wheel as may be desired, but the rear end of the
strip A of the supporting frame need not be made flexible.
As an alternative construction the strip A may be formed in two pieces adapted
to lie one over the other so that the cover C of the guard can be placed between
them as shown by Figures 10, 11, 12, 13, 14 and 15. In this construction the
double strip A is preferably made out of a length of thin steel bent double on
itself as shown by Figure 12, the end of one part of the strip forming a clip D to
receive the cover and if desired the end of the other part of the strip also. The
closed end of this double strip is attached to the crown of the fork of the
velocipede by a screw y or its equivalent, and at or near the other end of the strips
are holes a adapted to pass over a stud E carried by the crown of the supporting
fork B so that the double strip can be fixed thereto by a fly nut e or its equivalent.
To attach the cover C, the double strip is opened by removing the fly nut e, the
cover is then introduced between the two parts of the strip being guided into its
proper position by having a slot c¹ at one end to engage with the screw y and a
slot at the other end to engage with the clip portion D of the strip A and also
having a hole at or near its other end to fit over the stud E. The fly nut is
then screwed on to the stud E to lock the two parts of the strip A and the cover C
together, and to the crown of the supporting fork B. To more securely hold the
cover in position one or more holes e may be made in it for projections a¹ on one of
the strips to engage with, depressions or holes a³ being formed in the other strip
to receive the said projections, as shown by Figure 15.
I wish it to be particularly understood that I do not limit myself to the precise
details of construction hereinbefore described and illustrated by the accompanying
drawings, but that I hold myself at liberty to make such changes and alterations
as fairly fall within the spirit and scope of my invention.
