Improvements in Cycle Mud Guards.
I, WILLIAM BROOMHEAD of 277 Monument Road, Birmingham, in the County of
Warwick Mechanical Engineer do hereby declare the nature of my said 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 has for its object improvements in cycle mud guards by which I can
store them away into a compact form when they are not required without having to
interfere with any parts, and when they are required for use they can be fixed in a
very few minutes.
In order that my invention may be clearly understood and more easily carried into
practical effect I have appended hereunto a double-sized sheet of drawings upon which
I have illustrated examples of my improved mud guards.
Figure 1 is a front elevation of a back mud-guard constructed according to my
invention.
Figure 2 is a sectional view of Figure 1 without the guards A and B.
Figure 3 is a cross section of Figure 1 also without the guards A and B.
Figure 4 is a front elevation of my front mudguard constructed in a modified
form.
Figure 5 is a part of a sectional elevation showing one method for holding the
guards in position until they have been cleaned.
Figure 6 is a side elevation of a velocipede frame showing my mud guards in
position.
In carrying my invention into practice I form the case or cylinder C which may be
made from any metal or from celluloid vulcanite or other material with two loose
ends or caps cand e and inside this case I fix the smaller cylinder or tube D which
revolves freely on the spindle S in its bearings d' and d. The ends s' and 3 of this
spindle are square and fit into square holes formed in the centres of the caps c' and c³.
Fixed on this spindle inside the cylinder D and close to the bearing d' is a collar
which helps to keep the flat coiled or other form of spring s in position which spring
is placed between the bearing d and the collars one end being secured to the spindle
and the other end to the cylinder D as clearly shown at Figs. 2 and 3. The two
guards or protectors A and B (in the case of the back mudguard, Figure 1) are first
cemented or otherwise secured at one end to the cylinder D and then rolled around it
their other ends which pass through the slot or opening c³ being connected to the
rollers a¹ and respectively. These guards may be made from thin sheet rubber,
silk or other material or substance or from thin ribbon, steel or other metal.
When fixing my back nudguard I mount the ends of the spindle in any desirable
manner which may be in the position as shown at Figure 6 and then draw the guards
off the cylinder and attach the end a¹ to the bottom bracket K and the end b' to the
stay rods R the action of which winds up or tightens the coiled spring and when the
ends are released the spring unwinds thus wrapping or rolling the guards around
the cylinder D again.
In order to prevent the guards from coiling around the cylinder when their ends
are released until the mud has been cleaned off them I hinge the spring piece f in the
centre of the cylinder C (see Fig. 1) so that it presses upon the guards and holds
them which enables them to be cleaned and by pressing down the end f' they are
released. At Figure 5 I have shewn another method for keeping the guards unwound

page_text: until they are cleaned. In this case I form a ratchet h on the end of the cylinder D
and connect a spring catch h¹ to the inner face of the cap el or its equivalent and to
this spring I secure the headed pin which passes through a hole in the cap when
by pressing the head of this pin the spring catch takes into one of the teeth of the
ratchet and securely holds it until released by slightly drawing the guard forward
when the catch springs back into its normal position. The front mud guard may
have only one guard and this may be fixed to the machine as shown at Figure 6.
I may place a rubber washer on the ends of the spindle inside the cylinder C so as to
prevent the dirt from entering.
At Figure 5 I have shown a modification of my invention. In this case instead of
mounting the cylinder D in a case or cover I mount it in a frame E with or without
the end caps. I also form the ends and s of the spindle round and the centre.
portion square and mount it in bearings to correspond. On the end I secure the
handle W by turning which the guard A is wound upon the cylinder.
.Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is.
First. A mudguard for cycles consisting essentially of a case or cylinder such as C
or a frame such as E with an internal revolving cylinder such as D mounted on a
stationary spindle in combination with the one or more flexible guards such as A
and B capable of being automatically wound upon the internal cylinder in the manner
and for the purpose substantially as hereinbefore described and shown upon the
accompanying sheet of drawings.
Second. A mudguard for cycles consisting essentially of a frame such as E or a
case or cylinder such as C with a cylinder such as D mounted on a spindle capable of
revolving in combination with one or more flexible guards such as A and B capable
of being wound upon the cylinder such as D or its equivalent in the manner and for
the purpose substantially as hereinbefore described and shown upon the accompanying
sheet of drawings.
Third. Holding the guards such as A and B in the manner and for the purpose
substantially as hereinbefore described and shown at Figures 1 and 5.
Fourth. The improvements in cycle mudguards substantially as hereinbefore
described and shown on the accompanying sheet of drawings.
Dated this 5th November 1896.
