PROVISIONAL SPECIFICATION.
A New Mudguard for Velocipedes or other Vehicles.
I, WALTER HENRY BRAZIL, Physician, of Astley Bridge Bolton-le-Moors.
Lancashire do hereby declare the nature of this invention to be as follows:-
The object of this invention is to provide a light, readily detachable, portable
and efficient mudguard for velocipedes or other vehicles.
This mudguard consists of a flexible and elastic framework of thin sheet steel
manufactured into a U or other suitable shape on section, or of whalebone, or other
suitable material; and may be furnished with hinge or other joints in order to
admit of more compact stowage. This framework is covered with fine wire gauze,.
canvas, sheet aluminium or other suitable material.
Detached from the machine these guards lie perfectly flat, but when fitted they
follow the curve of the wheel. This is accomplished by means of lateral tension.
wires or strings, disposed in a convenient and suitable manner.
The side stays are attached by means of a hinge, and may themselves be jointed
in the course of their length.

COMPLETE SPECIFICATION.
A New Mudguard for Velocipedes or other Vehicles.
I WALTER HENRY BRAZIL of Astley Bridge Bolton le Moors in the County
of Lancaster, 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 object of this invention is to provide a light readily detachable portable and
efficient mudguard for velocipedes or other vehicles.
The nature of my said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference to
the drawings hereunto annexed and the following explanation thereof.

The drawing illustrates the application of my invention to a bicycle of the
safety" type,
Fig. 1 being a side elevation of the bicycle with my improved mudguard shown
as applied thereto.
Figs. 2, 3, 4, 5, 6 and 6ª are detached views hereafter described. Figs. 2, 3, 4
and 5 being drawn to a larger scale.
The improved mudguard consists principally of a flexible and elastic framework a
preferably made of thin steel of a U or other suitable shape in section, or made of
whalebone or other suitable material, and (especially as regards the hind wheel)
may be furnished with a hinge or joint as at b, in order to admit of its being folded,
(as shown at Figs. 1 and 2) for more compact and convenient stowage. The
frame-work a is covered with fine wire gauze, canvas, sheet aluminium or other
suitable metal or material (see Fig. 3).
In some cases, where sheet metal is used, I propose to dispense with the light
steel frame and to stiffen the edges of the metal by forming a longitudinal groove
or corrugation along each side thereof, as shown at Fig. 4.

page_text: When detached from the machine these guards will lie perfectly flat and will
occupy but a very small space for storage, but when fitted to the machine they
follow the curve of the wheel, as seen at Fig. 1.
This curvature is obtained by means of lateral tension wires or strings e disposed
and arranged in such a convenient and suitable manner as to act on the principle of
a bowstring, and maintain the guard a in the required curved form. In the
arrangement shown on the front wheel, one end of the mudguard is placed against
the crown d of the fork (see also plan view Fig. 6) the tension wires c being
connected to the other end of the mudguard a at either side or edge thereof, and
the wires c are then drawn tight and fixed to hooks d on the said fork, and will
not only cause the guard a to be bent to the required curve but also fix the same
firmly by causing its end to abut against the fork d, by virtue of its own
elasticity.
In the case of the rear mudguard (see Fig. 1) the wires c instead of being
connected to the fork d¹ are or may be connected to the fork d², the hinge b, or
other projection if necessary, serving to abut against the said fork and preserve
the correct curve throughout the whole length of the mudguard a the end of which
abuts against the fork d (see also Fig. 6).
The other end of the guard a is connected by means of hinges or otherwise to
side stays or struts e, the other ends of which are provided with eyes e¹ (see Figs. 1
and 5) which may be passed over the ends of the axle pin and secured by the
usual nuts. In some cases for large wheels these stays or struts e may be made
with a joint in the course of their length, so that they may also be folded for more
convenient storage if required.
To avoid the necessity for unscrewing the nuts at the end of the axle pin when
it is desired to remove the mudguards, instead of making an eye at the end of the
side stays or struts e I provide short tubular sockets (see Figs. 1 and 5) which
are held by the nuts and remain permanently secured to the machine, the ends of
the stays or struts being made to fit into such sockets so that all that is required
to remove the mudguard is to release the tension wires or strings c and withdraw
the ends of the stays e from the sockets f, when the whole will readily come away
and may be folded flat for storage.
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 :-
A detachable mudguard for velocipedes or other vehicles formed of a flexible
and elastic frame covered with wire gauze or other suitable material, or of a thin
elastic and flexible metal or other plate stiffened at the edges, formed into a bow
when in use by lateral tension wires or strings (acting like a bowstring) and
supported by detachable side stays or struts, so that when detached the same will
lie flat and can be folded and packed in a small space, substantially as hereinbefore
described and illustrated by the drawings annexed.
