page_text: I HENRY STUTTLE of Enfield (No. 2 Stanley Villas) in the County of Middlesex
Gentleman do hereby declare the nature of this invention to be as follows:-
The brake consists of a wheel or drum fixed to the bicycle either on the pedal axle
or crank or on the axles of the other wheels. Around this is a band belt or chain
one end of which is fixed to a connection on the machine. The other end is attached.
to a cord wire or otherwise and by being pulled either by the usual brake handle or
otherwise is pressed against the wheel or drum.
The following is a detailed description.
To the pedal axle A Fig. 1 of an ordinary bicycle is attached the grooved drum B
which is kept in position by three projections (C D & E) from the hub of the said
wheel or drum, fitting around the upper portion of the pedal crank F and through.
he lower two of which C & E passes the bolt E, e, used in keying the crank to
the shaft A and which is also utilized in this invention for securing the grooved drum
or wheel B.
On that portion of the frame of the bicycle marked G at the rear of the pedals are
clamped two metal plates, H aud J, (Figs. 1 and 2) the upper of which carries a
small projection or shaft J (Figs. 1 and 2) to which is secured one end of the metal
belt or band (K, Fig. 1) and immediately within the attachment of the said band on
the said shaft is pivoted the arm L and the said metal belt or band passing around
the grooved druin or wheel 13 is fastened to the said arm at M, (Figs. 1 and 2). To
the arm I at N (Figs. 1 and 2) is attached the steel rope rod or cord O, which passes
under the small grooved wheels, P, P, (Figs. 1 and 3) which are secured to that
portion of the frame of the Bicycle, Q, (Figs. 1 and 3) and over a similar grooved
wheel R (Fig. 3) to the ordinary brake lever of the machine S, (Fig. 3) to which it
is secured.
By pressing the brake lever S, (Fig. 3) the wire rope rod or cord O, (Figs. 1 and 3)
pulls the arm L (Fig. 1) forward causing the metal belt band or chain, K, (Fig. 1)
to grip the grooved wheel B, this applying a powerful and effective brake, without
causing chafing and wear of tyre &c as experienced in the existing lever brake.
Dated this 24th day of August 1896.
HENRY STUTTLE.

page_text: in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
A band belt or chain around a drum or wheel attached to pedal axle or crank or to
either axle of wheels for purposes of a brake as more fully described below.
To the pedal axle of an ordinary bicycle as shewn by the letter A Figuro 1, is
attached the grooved drum or wheel B (Fig. 1) which is cast in one piece with the
pedal crank Fig. 1 and of which the said crank partly forms one of the spokes.
On that portion of the frame of the inachine marked D Figs. 1 and 2 immediately
at the rear of the pedal are clamped two metal plates E and F Fige. 1 and 2
the upper of which (F) carries a shaft or projection G; Figs. 1 and 2 to which is
attached one end of the metal band or belt H, Figs. 1 and 2 and on which is also
pivoted the arm I Figs. 1 and 2. From the projection G the said belt or band passes
around the said drum or wheel and is secured at, the other end to the arm I at J,
Figs. 1 and 2 to the lower end K; of the arm I is pivoted the curved metal L, Fig. 1
to which is secured one end of the steel rod N Figs. 1 and 3 which passes along
that portion of the frame of the machine marked N Figs. 1 and 3 and is attached at
the other end to the elbow O w ich is in turn pivoted to the frame of the machine;
(see Fig. 3) from O is jointed the steel rod P (having an adjustable screw at Q) which
is attached to the ordinary brake lever of the machine Figure 3.
On pressing the brake lever the rod P forces down one end of the elbow O which
pulls the rod N and the arm I, Fig. 1 thus causing the said metal band or belt to
grip around the said drum or wheel applying an effectual and powerful brake
without causing the friction wear of tyre etc., as experienced in the existing brake
now in use.
Having now particularly described and ascertained the nature of any said invention
and in what manner the same is to be performed I declare that what I
claim- is:-
