We, WILLIAM BENJAMIN SPIKINS, of 34, Western Road, Hove, Sussex, Merchant,
and ALFRED HERBERT MAYES, of 31, Western Road, Hove, Sussex, Electrician,
do hereby declare the nature of this invention to be as follows:-
This invention refers to roller brakes for bicycles and other vehicles having
rubber tires and consists of a controlled rotating roller of special construction with
a hollowed periphery, which roller bears on the sides of the tire and not on the
tread or wearing part. This roller is held in an adjustable fork in the usual way
and is constructed of three parts; a metal centre and two projecting rims. The
metal centre does not come into contact with the tire, but engages with the head,
or end, of the controlling rod which receives the pressure applied to the brake
handle. This metal centre takes the hard wear of the friction and removes it from
the softer part of the roller, such as the projecting rims or sides which run on
the tire. These sides or rims are hollowed or shaped to suit the configuration of
the tire. The head or end of the controlling rod is shaped to fit and partly
embrace the metal centre of the roller, and may be faced with hard rubber, wood,
leather, or any suitable frictional surface, adapted to engage with the metal centre.
The sides or rims of the roller are by preference faced with hard or soft rubber,
or other substance suitable for a rolling pressure contact with the rubber tire.
The fork in which the roller is journalled is preferentially attached to a sleeve
which slides on the controlling rod, and may be fitted with a pin and slot, or made
of a square or other suitable section, to avoid turning out of position. When the
brake rod is raised, a collar, or pin, or other suitable device. enables it to lift the
roller away from the tire, and when the brake pressure is applied, the rod carries
the roller down with it, causing it to engage with the tire, and then pressing
against its centre, causes it to brake the wheel by its pressure on the periphery.

This invention refers to roller brakes for bicycles and other vehicles having
rubber tires and consists of a controlled rotating roller of special construction with
a hollowed periphery, which roller bears on the sides of the tire and not on the
tread or wearing part. This roller is held in an adjustable fork in the usual way
and is constructed of three parts; a metal centre and two projecting rims. The
metal centre does not come into contact with the tire, but engages with the head,
or end, of the controlling rod which receives the pressure applied to the brake
handle. This metal centre takes the hard wear of the friction and removes it from
the soffer part of the roller, such as the projecting rims or sides which run on
the tire. These sides or rims are hollowed or shaped to suit the configuration of
the tire. The head or end of the controlling rod is shaped to fit and partly
embrace the metal centre of the roller, and may be faced with hard rubber, wood.
leather, or any suitable frictional surface adapted to engage with the metal centre.
The sides or rims of the roller are by preference faced with hard or soft rubber,
or other substance suitable for a rolling pressure contact with the rubber tire.
The fork in which the roller is journalled is preferentially attached to a sleeve
which slides on the controlling rod and may be fitted with a pin and slot, or made
of a square or other suitable section, to avoid turning out of position. When the
brake rod is raised, a collar, or pin, or other suitable device; enables it to lift the
roller away from the tire, and when the brake pressure is applied, the rod carries
the roller down with it, causing it to engage with the tire, and then pressing
against its centre, causes it to brake the wheel by its pressure on the sides of the
tire which forms its periphery
We will now describe the invention with reference to the accompanying draw-
ings in which:
Fig. 1 shews a side elevation of the front portion of a bicycle fitted with our
improved brake.
Fig. 2 shews an enlarged front elevation of the brake.
Fig. 3 shews a section on line x-x of Fig. 2.
Fig. 4 shews a modification.
C
a is the metallic centre pin of the brake roller. a¹ is a central boss on the pin a,
which receives the friction of the brake shoe when the pressure is applied.
The
pin a is provided at each end with the bevelled rims bb faced with rubber or other
suitable material, which rims together form the bearing surface of the brake
roller. The brake roller is supported in the forked bearing c by means of the
adjustable screws d, which can be screwed up to cause the metal centre pin a to
run more or less tightly. e is a sleeve preferably formed solid with the forked
bearing c, and projecting upwards therefrom, through which the brake operating
rod passes. The latter is terminated at its lower end by a collar f² and a brake
shoe f¹. The collar 2 carries the brake roller and forked bearing. The sleeve e
is supported by a bracket g screwed into or otherwise attached to the fork crown of
the machine. The bracket 9 is provided with an eye g¹ which receives the sleeve e.
The brake rod f is operated from the handle bar in the usual way. A suitable
spring such as a V spring, is interposed between the brake handle and handle bar
to return the brake to its normal or rest position after being applied.
g
Referring to Fig. 4. The use of the bracket g is in this case dispensed with,
and is replaced by arms h h one end of each of which is pivotted at h¹ to the sides
of the fork crown. Their other ends are attached to either end of the brake roller.
The method of working the brake is by means of the usual hand lever attached
to the handle bar in the ordinary way.
Having now particularly described and ascertained the nature of our said Inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:-
:--
1. In a brake for rubber tired wheels, the rod and shoe f f¹ the rims b b with

2. In a roller brake for rubber tired wheels the controlled roller with bevelled
side bearing rims, forked holder c, controlling screws d d sleeve e and shoe f¹, as
herein described and set forth.
