PROVISIONAL SPECIFICATION.
An Improved Band Brake for Cycles.
We, RICHARD MORRISS WOODHEAD, and PAUL ANGOIS, of Russell Street,
Nottingham, Cycle Manufacturers, do hereby declare the nature of this invention
to be as follows:-
In carrying out our invention, we divide the brake band into sections, preferably
using only two. Each of these sections is fixed at one end, and arranged to stand
over and clear of the frictional surface of the drum. The other ends of the sections
are all suitably attached to the same lever, or disc, which pivots on the same axis
as the drum. The gear used for applying the brake is also connected to this lever.
When not in use, the bands are suspended clear of the drum. When it is required
to apply the brake, the loose ends of the bands are pulled by the action of suitable
gear, away from the fixed ends, thus straightening and forcing them into contact
with the drum.

COMPLETE SPECIFICATION.
An Improved Band Brake for Cycles.
We, RICHARD MORRISS WOODHEAD and PAUL ANGOIS of Russell Street,
Nottingham, Cycle Manufacturers 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 object of our invention is to construct a band brake for cycles, so arranged
that no impediment to propulsion can be caused by contact between the drum and
friction band when the brake is not in use. Our device also enables the maximum
of friction to be applied to the brake drum without causing unequal pressure or
strain upon the wheel bearings, thereby preventing excessive wear, liability to
fracture, or deflection of the parts from their true position.
In carrying out our invention we divide the brake band into sections, preferably
using only two. Each of these sections is fixed at one end and arranged to stand
over and clear of the frictional surface of the drum. The other ends of the sections
are all suitably attached to the same lever or disc which pivots on the same axis as
the drum.
When
The gear used for applying the brake is also connected to this lever.
not in use the bands are suspended clear of the drum. When it is required to apply
the brake the loose ends of the bands are pulled by the action of suitable gear
away from the fixed ends, thus straightening and forcing them into contact with the
drum, and in order that our invention may be clearly understood, reference is here-
after made to the accompanying drawings, in which similar letters of reference
indicate corresponding parts.
Figure 1 illustrates a modification of our device as we apply it to the driving
wheel-hub of a safety bicycle. Both figures shew the relative position of the parts
when the brake is not in use. In Fig. 1. the parts comprising the brake only are
shewn, but in Fig. 2. which is an end elevation of the same parts, the manner in
which the brake is mounted upon the hub and wheel axle, is also illustrated.
a is a disc, mounted upon the axle h, of the wheel hub, and free to turn thereon.
