Improvements in Brakes for Velocipedes.
Year: 1897

page_text: Improvements in Brakes for Velocipedes.
I, WILLIAM WATSEN, of Mannheim, in the Grand-Duchy of Baden, German
Empire, do hereby declare the nature of this invention to be as follows:-
-
The brakes which are now used on pneumatic tyres are all rigidly held in place
and when pressed down upon the tyre there is such a friction that the rubber
heats and wears, when the roads are wet, the sand picked up by the tyre causes
still more wear and tear.
In order to avoid this difficulty I have placed a rubber roller between the rigid
hrake and tyre and so arranged or diminished its rubbing surface that no matter
how great the pressure the roller will always turn with the tyre, when in contact
with it and the injury will be sustained by the roller and stationary object above
it. The accompanying drawing clearly illustrates the principle.
The little rubber roller C, when pressed down on to the tyre has more of its
surface in contact with the tyre than with the rigid part and consequently will
always turn with the tyre and all the friction will be on the rigid part d and the
roller C. The fork holding the roller is slotted so that the part d may be in
contact with the roller when the latter diminishes by wear.

I, WILLIAM WATSEN, of Mannheimi, in the Grand-Duchy of Baden, German
Empire, 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:-
The brakes which are now used on pneumatic tyres are all rigidly held in place
and when pressed down upon the tyre produce such friction that the rubber
becomes hot and wears when the roads are wet, furthermore, the sand picked up
by the tyre increases the wear and tear.
In order to avoid this difficulty I have placed a rubber roller between the rigid
brake and tyre and so arranged or diminished its friction surface, that no matter
how great the pressure, the roller will always turn with the tyre, when in contact
with it, and injury will be prevented by the roller and stationary object above it.
The drawing filed with the Provisional Specification clearly illustrates the principle.

page_text: The small rubber roller C, when pressed down upon the tyre has more of its
surface in contact with the tyre than with the rigid part and consequently will
always turn with the tyre thus all the friction will be on the rigid part d and
the roller C. The fork holding the roller is slotted so that the part may still
be in contact with the roller even when the latter diminishes by wear.
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:
In an improved brake for velocipedes and the like, the arrangement of a roller
of rubber or other suitable material, in contact with a stationary brake. in such
manner, that the friction between the roller and the brake, is less than the friction
between the said roller and the tyre, substantially as described.
