AN IMPROVED BRAKE FOR VELOCIPEDES, HACKNEY COACHES, AND OTHER VEHICLES

We, BENJAMIN KETTLE of Broomfield Place, Headingley, near Leeds, in the
county of York, Engineer, and HENRY JAMES BROOKES of Cape Works, Smethwick
in the County of Stafford, Manufacturer, do hereby declare the nature of our
invention for AN IMPROVED BRAKE FOR VELOCIPEDES, HACKNEY COACHES, AND
OTHER VEHICLES to be as follows:-
'
The object of this invention is to make a band brake which by acting uniformly
nearly all round the drum usually attached for brake purposes to Velocipedes, will
impart increased brake power. The drum is constructed as usual except that
owing to the increased power obtained it may be reduced in size. Upon the frame
of the Velocipede a stud or pin is fixed, and on this stud a short lever or hinge is..
allowed to work freely. This lever, at the opposito end from that which works on
the stud, is fixed to the band brake. The band brake apart from the above-
mentioned lever we generally construct as usual, sometimes the leather lining being
however dispensed with. The ordinary brake handle is attached to the other end
of the band brake. When the brake power is applied by the brake handle in the
usual manner it causes the abovementioned lever to close in upon the drum which
is thus tightly gripped nearly all round by the band brake to which it is attached.
The increased power of this brake is caused by the abovementioned lever being
placed at an angle to the drum, and as the brake is gradually being applied the
angle between the drum and the lover gradually becomes greater until the
maximum power required is obtained.
It is evident that this arrangement of brake, owing to its great power can be
applied to the naves or hubs of hackney coaches and other vehicles.

We BENJAMIN KETTLE of Broomfield Place, Headingley, near Leeds, in the
County of York Engineer, and HENRY JAMES BROOKES of Cape Works, Smethwick
in the County of Stafford, Manufacturer, do hereby declare the nature of our
invention for AN IMPROVED BRAKE FOR VELOCIPEDES, HACKNEY COACHES AND
OTHER VEHICLES 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 this invention is to make a band brake, which, by acting uniformly
nearly all round the drum usually attached for Brake purposes to Velocipedes, will
impart increased brake power The drum is constructed as usual except that owing
to the increased power obtained, it may be reduced in size. Upon the frame of the
Velocipede a stud or pin is fixed, and on this stud a short lever or hinge is allowed
to work freely. This lever, at the opposite end from that which works on the stud
is fixed to the band brake. The band brake apart from the abovementioned lever
we generally construct as usual, sometimes, the leather lining being, however,
dispensed with. The ordinary brake handle is attached to the other end of the
band brake. When the brake power is applied by the brake handle in the usual
manner it causes the above mentioned lever to close in upon the drum which is
thus tightly gripped, nearly all round by the band brake to which it is attached.
The increased power of this brake is caused by the abovementioned lever being
placed at an angle to the drum, and as the brake is gradually being applied the
angle between the druin and the lever gradually becomes greater until the
maximum power required is obtained.
It is evident that this arrangement of brake owing to its great power can be
applied to the naves or hubs of Hackney Coaches and other Vehicles.
The accompanying drawings show the method of carrying out this invention.
Fig. 1 is the brake at rest, Fig. 2 is a modification of brake, Fig. 3 is the brake at
work. The brake drum a Fig. 1 is similar to what is generally used in Tricycles
and works on the axle of machine 6 as usual, The Brake band c has generally a
leather lining d secured to the brake band in the usual manner. At each end of
the brake band, an ear ef is placed to which the levers or connecting links, g h are
attached, working freely on pins or studs, The other ends of these levers also
work freely on pins or studs fixed into the lower part of the brake handle, i. On
a continuation of one of these studs or pins ; the brake handle works, the stud j
When the
projecting through a lug attached to the frame of machine shown at h.
brake handle is pulled forward, the lever is also raised. This pulls up the band
brake and simultaneously causes the lever to assume a more vertical position,
thus pressing the band tightly against the drum nearly all round as shown in Fig. 3;
of course it is important that the lever should always be made sufficiently long
to prevent it assuming a perfectly vertical position with the stud j and the axle b
otherwise it will pass over its centre, and thus make the brake useless.
Fig. 2, indicates a cheaper method of forming a brake embracing the principle
of the invention. Instead of the lover g the band brake is continued as shown

page_text: at this being the usual method of constructing band brakes. At the other end of
brake band instead of the lever h we use an arrangement as shown at m which
consists of a piece of spring steel or other suitable material and sufficiently strong,
and which either forms part of, and is a continuation of the brake band or is
secured thereto in a suitable manner. Upon the Brake handle being pulled the
action of this arrangement would be precisely as described above.
Instead of the lever working on a centre stud at ; where the brake handle
works, it can be made to work on a stud to the right of the centre stud j. This
will make the brake more rapid in its action.
It is evident that the details can be modified without departing from the principle
of the invention, The driving wheels of the Tricycle can also, of course, work
either backwards or forwards, as the brake will operate in either direction.
Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed, we declare that what
we claim is
1. The use of the lever or connecting link h. Fig. 1 and 3 substantially as
described, either in combination with the lever g or with the continuation of brake
band l.
2. The use of the arrangement of parts shown at m Fig. 2, in lieu of the lever
or connecting link h in Fig. 1 and 3.
