Improvements in Mudguards for Bicycles, Tricycles, Velocipedes,
and other Wheeled Vehicles.
1, JAMES JOHN BOLT of Number 2 High Street Sidmouth, Devon, Watchmaker do
hereby declare the nature of this invention to be as follows:-
A spring joint in the lower portion of the mudguard attached to the front wheels
of bicycles, tricycles, velocipedes or other wheeled vehicles, the two portions of the
mudguard being hinged together and a pin attached to the lower portion of mudguard
bears on a spiral spring contained in a tube attached to the upper portion of the
mudguard.
The spring joint is provided to guard against accidents through the mudguard-
catching against stones or other obstructions on the road as is the case when the
mudguard is in one fixed piece. On meeting with any obstruction the hinged joint
allows the lower portion of the mudguard to pass over such obstacle, while the pin
bearing against the spring compresses it and on the obstacle being passed over, the
recoil of the spring causes the lower part of the mudguard to return to its former
position.

JAMES JOHN BOLT of Number 2 High Street, Sidmouth, Devon Watchmaker,
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 accompanying drawings show this invention applied to the front wheel of a
Tricycle, it is, however, equally applicable to any wheeled vehicle, as claimed in title.
The lower portion of mudguard is hinged to allow it to pass over any obstruction
as shown in accompanying drawings. The two portions of the mudguard A, a, are
connected by the hinge B. In a case C attached to the upper portion of mudguard A,
is contained a spiral spring I) to the lower end of which is attached the head E, of
the rod F, the lower end of which G, is linked to an eyebolt H in the lower portion of
mudguard a. On the mudguard a, meeting with stones or other obstructions on the
roadway, the hinged joint B allows the lower portion a to pass over the obstruction.
this portion of mudguard a, being raised the rod bearing on the eyebolt H, is raised
accordingly and compressing the spring D, on the obstacle being passed over, the
recoil of the spring forces the mudguard a into its normal position as shown by I
in figure 2 of drawings.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, I declare that what I claim is :-
That the hinged joint in mudguard with spring attachment is conducive to greater
safety in travelling, by reason of the reduction to a minimum of the injury or
danger from meeting stones or other obstructions in the roadway, and that greater
comfort and cleanliness in travelling is ensured by reason of the above mentioned
attachment allowing the mudguard to be made of sufficient length to be an
efficient protection against mud and dust thrown up by the revolution of the
wheel, as with those mudguards in present use if made sufficiently long to be an
efficient protection against mud and dust, accidents frequently happen by the
mudguard catching against obstructions in the roadway.
