PROVISIONAL SPECIFICATION.
A New and Improved Plan of Mud-guards, Dress-guards, and Gear
and Chain Covers for Cycles, so as to be easily detachable
therefrom.
ALEXANDER NICHOLSON, 52 Mary Street, Dublin Engineer, do hereby declare
the nature of this invention to be as follows:-
For wheel mud-guards, a frame of small metallic tubing or casing, having a
longitudinal split or opening, is attached to machine, into which is secured both
edges of a strip of leather, rubber-cloth, canvas, or other suitable material
preferably of an elastic nature, by means of beads formed on the edges, which
when inserted into ends of tubes, at both sides, and the strip drawn up between
them is securely held therein.
The ends being fastened in a similar or other manner to be afterwards described.
The bottom cross-piece of front wheel mud-guard, to have also a groove on its
underside, or be similar to H shape in section into which is secured in a similar
manner as already described, one edge of a piece of leather, of suitable size
reaching near the ground, to prevent mud splashing on feet of rider, and crank-
axle of machine.
The tubing of framing, can if desired he made in lengths, to slide into each other
when not in use, the stays swinging where connected at centre of wheel, or having
a suitable joint for the purpose.
For dress-guards, and gear and chain covers, the tubing or casing is fixed, in the
necessary shape and position on machine, into which is secured the edges of the
leather or other covering material of guard, by a bead on the edges, as described
for mud-guards.
In case of where the shape of the guard, would prevent some of the edges being
passed into the tubing as described, such edge or edges, can be fastened in by having
them prepared with a casing or hem, which being closed together, and run sideways
into the tube through the split, is retained therein by passing into it, from the end,
a suitable core or packing.
The covering material of guards, can have cross-pieces of brass or cane, attached
at suitable intervals, and of such a length, as to pass between the tubes of framing,
to prevent them from drawing towards each other, by the pull of the cover.

COMPLETE SPECIFICATION.
A New and Improved Plan of Mud-guards, Dress-guards, and Gear
and Chain Covers for Cycles, so as to be easily detachable
therefrom.
I, ALEXANDER NICHOLSON, of 52 Mary Street, Dublin, Ireland, Engineer, 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 for a new and improved plan of mud guard, dress guards, and
gear and chain covers for cycles so as to be easily detachable therefrom, consists
essentially in fixing to the machine frame a metallic skeleton and hollow frame
conforming to the outer edges of the usual guards or gear cases and having in its
opposite sides and facing one another longitudinal slits, along which a strip of
.

page_text: leather, canvas or other suitable substance having beads or ridges at its edges is
drawn along so as to completely close up or cover the skeleton frame and form the
required guard or case, the two beads or ridges passing within the two sides of the
hollow guard frame and preventing the strip from being drawn out of the frame.
A broad splash guard reaching nearly to the ground is secured by its upper edge in
a similar manner to the bottom cross piece of the front wheel mudguard to prevent
mud splashing on to the crank axle or feet of the rider.
The skeleton guard frame is made in one rigid piece or is made in two or more
parts adapted to slide one within the other, the stays fixing the guard frame to the
machine pivotting about the centres of the wheels or being themselves suitably
jointed. The beads or ridges on the cover strips are either part of the strip or the
edges of the strip are formed with a hem and afterwards expanded by a wire or
other suitable core inserted within the fold. This latter arrangement is preferable
in cases where the shape of the guard would prevent the cover strip being drawn
in as above described; in these cases the collapsed edges of the strip are passed
sideways through the grooves and are afterwards expanded. The cover strips are
formed at suitable intervals with stiff cross pieces extending between the two side
pieces of the guard frame and preventing them from being drawn together.
In the accompanying sheet of drawings
Figure 1 shows a longitudinally slotted metallic tube suitable for constructing
the skeleton guard or case frame.
Figure 2 is a section of a cover strip.
Figure 3 is a perspective view of a skeleton guard frame for the rear wheel of a
bicycle provided with supporting stays.
Figure 4 is a plan of a part of the guard frame shown in Figure 3, the cover
strip being shown in position.
Figure 5 is an elevation of a stay for supporting the guard frame at any point
of its length and adapted to be fixed on the wheel axle.
Figure 6 is an enlarged view of the ends of the guard frame adapted for the
insertion of the cover strip endwise.
Figure 7 is a perspective view of the guard frame of the front wheel of a bicycle
provided with supporting stays and
Figure 8 is a view of the splash guard adapted to be attached to the guard frame
shown in Figure 7.

The rear wheel mud guard, constructed out of tubing slitted longitudinally as
shown in Figure 1 is made in two parts a b, the part a being fixed and the
part 6 adapted to slide in the part a. The part a is provided near its ends with
cross pieces ce through which bolts are passed to fasten it to the machine, and the
inner end of the part 6 is provided with a cross piece d adapted to slide in the
grooves in the part a. By means of the small bolt passing through holes in
the cross pieces e d. and. serving to secure the frame a b to the machine the
parts a 6 are fixed in their extended position as shown and when the bolt is with-
drawn the cross piece d is released and the part 6 is telescoped within the part a and
can be secured in this position by a small bolt passed through holes in the cross
pieces c, d and serving to secure the part a of the frame to the machine, the bolt
passing through the piece e being also replaced. The part 6 of the guard frame
is stayed by the rods 9h pivotting at one end about the wheel axle and secured
at their. other ends to the guard frame. These stays take the position, shown in
dotted lines gh' when the part 6 is telescoped into the part a. If desired
additional stays secured to the part 6 by the clip shown in Figure 5 which is
mounted on the axle by means of the rods ii and is situated near, the dotted
lines g¹ h¹.
b
The cover strip for the back guard is made in two pieces inserted from the outer
ends through the slots / Figure 6 and provided at their adjacent ends.with holes m
through which passes the bolt securing the parts a b.
If desired the back wheel guard frame can be made in one piece and in this case
the cover strip is also made in one or two pieces.

page_text: The front wheel guard frame o Figure 7 is provided at its lower end with the
slitted tube p to receive the bead or ridge r of the splash guards Figure 8.
Having now particularly described and ascertained the nature of my said inven
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A guard cover or case for a cycle consisting of a metallic skeleton and hollow
frame conforming to the outer edges of the usual guards or cases and having in its
opposite sides longitudinal slits and in which a flexible strip is secured by beads or
ridges at its edges substantially as described.
2. In a cycle, a splash guard consisting of a flat piece of leather or like material
provided with or adapted to have formed on its upper edge a ridge or bead and of
a slotted tube fixed in the desired position and adapted to retain the flat piece
substantially as described.
3. A guard case or cover for cycles constructed substantially as described with
reference to the drawings.
