PROVISIONAL SPECIFICATION.
A Band Brake, and its Method of Adaptation to a Pneumatic Tyred
Safety Bicycle.
LOUIS RUSSELL 52 North End Road West Kensington London W. Electrical
Engineer do hereby declare the nature of this invention to be as follows:-
A hard wood or composition disc fitted to spokes or hub, or both, of front wheel
& acted on by a steel band fixed to fork & passing round disc & fixed to a
connecting rod which is fitted with a replacement spring & stop & passes
through a guide, up to lever, at handlebar & secured with knuckle & screw.
The lever fitted on front of handlebar & the haudle of lever adjusted to stand
in front of handle.
The brake is thrown into action by pressing the finger on handle of lever
causing connecting rod to pull up & tighten band round disc. The wheel
travelling in same direction as the band tightens assists in pulling up machine-
without any effort on riders part.

COMPLETE SPECIFICATION.
A Band Brake, and its Method of Adaptation to a Pneumatic Tyreď
Safety Bicycle.
LOUIS RUSSELL 52 North End Road West Kensington, London, W. Electrical
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 :-
A hard wood or composition disc fitted to spokes, or hub, or partly to both, of front
wheel. A steel band fixed to fork & passing round edge of disc & fitted to a
connecting rod which is fitted with a replacement spring & an adjusting stop, &
passes through a guide up to a lever which is fixed at handlebar & operated by
pressure from the hand. I now proceed to refer to drawings.
A is the disc of hard wood or a suitable composition which may be fixed to
spokes by means of a halved back plate of wood or metal & pulled to outer disc
by means of screws, & clamping all spokes firmly into grooves previously cut in
disc to receive them. B is a band of steel which may be flat or half round with
one end fixed to a square or oval stud fixed in fork, & then passing round disc in
same direction as wheel rotates, to loose end with tension set to keep slightly open
& away from disc when not in operation. C is a steel rod made in 1 or 2 parts for
use with adjustable height of head, & fitted to loose end of band B by a loose
knuckle, & passing up through a guide to D. D is a lever, fixed in front of
handlebar as shewn, or beneath it, swinging on a pivot & having a knuckle
attachment to receive end of rod C, & operated on with the hand, by down pressure
in the case of lever fixed as on drawing & by lifting up in the case of lever fitted
beneath handlebar which in either case will draw up rod C & tighten band B.
E is a guide which can be fixed to any convenient part of fork, or be replaced by
CD

page_text: a hole in crown of fork, to allow rod to pass through. F is a small coil spring
fitting round rod C & depressed between guide E & a flange on rod C just below
guide E to replace brake after use & keep in position. G is a stop, slipped down
rod & fixed with a tightning screw, to rest on guide E when band B & lever D are
in position.
Having now particularly described & ascertained the nature of my said inven-
tion & in what manner the same is to be performed, I declare that what I
claim is
1. That a wood or composition disc or drum has advantages over metal & is a
novelty in this form.
2. That the rod, pulling the brake on instead of pushing it on, can be made of
much thinner & consequently lighter metal, & will not bend in use & is therefore
a novelty as lightness & durability are important features.
3. That the clutch or steel band being firmly fixed at its starting end & haveing
its tension set to keep open, enables the rider to use the momentum of his
machine to assist at its stopping, since it tightens in the way the wheel rotates & is
therefore a novelty.
