PROVISIONAL SPECIFICATION.
An Improved Safety Roller Brake for Velocipedes and Cycles
of any kind.
I, ALBERT BRADFORD of No. 175 Sturt Street, Ballarat in the Colony of
Victoria Cabinet Maker do hereby declare the nature of this invention to be as
follows:-
This invention has been devised for the purpose of providing a safety roller
brake for velocipedes and cycles of any kind which will not injure the tyres so
much as the ordinary spoon brake and yet be quite as effective and much safer
in use.
It consists essentially of a roller or wheel mounted loosely in vertical slots in
the arms of a bracket secured to the lower end of the ordinary brake bar upon
which latter is also secured (preferably by a clip and thumbscrew) a brake block
or shoe which when the brake is applied comes in contact with and retards the
rotation of the roller above referred to and thereby tends to arrest the movement
of the velocipede wheel as will be well understood.
By this means there is a rolling contact between the brake and the tyre and
moreover the effect of the brake can be more evenly regulated than is possible
with those at present in use whilst the wear and tear on the tyres is considerably
lessened.
If preferred the brake bar may be fitted with a piece of rubber in order to
lessen the friction on the small brake wheel or roller.

An Improved Safety Roller Brake for Velocipedes and Cycles
of any kind.
I, ALBERT BRADFORD of Sturt Street, Ballarat, Victoria, Australia, Cabinet
Maker, do hereby declare the nature of my invention for an Improved Safety
Roller Brake, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
An
My invention is as follows:-Between steel supports A. which have slots B. of
about inches in length is fitted a steel roller C. about 1 inches in diameter.
axle d. passes through it, both ends of which fit loosely into the slots of the
supports. The combination is fitted to the usual steel rod, connecting the brake
with the hand-grip. Attached to the supports is a bar, e. holding a small piece of
rubber F. projecting over the roller. When the brake lever is pressed, down goes
the roller on to the wheel of the bicycle; the roller axle is forced up the slots
and the roller is thus brought into contact with the small piece of rubber. The
more force there is used on the hand lever the greater the pressure against the
small rubber, and, of course, against the tyre of the bicycle; the roller continuing
to revolve and yet acting as a perfect brake to the speed of the bicycle.

page_text: The steel roller has rubber rings g. fixed round the edges to prevent it injuring
the tyres of any wheels it may be applied to.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed; I declare that what I
claim is.―
1st. That my brake, through its rolling motion, does no injury to any tyres that
it is applied to.
2nd. That, by the pressure of the small piece of rubber on the roller, it acts
perfectly in retarding or stopping the vehicle to which it is applied.
3rd. That the pressure can be perfectly regulated.
Dated 28th June 1895.
