Complete Specification Left, 13th Dec., 1894-Accepted, 19th Jan., 1895
We ROBERT POWELL, Cycle Manufacturer and HENRY CHARLES POWELL,
Cycle Manufacturer both of Abergavenny, do hereby declare the nature of this
invention to be as follows:-
This invention relates to a new or improved brake for cycles, especially
applicable for use with pneumatic tyres, and is intended to provide a brake which
will not injure the tyres in any way, while at the same time being thoroughly
effective in controlling the machine.
The brake we propose to employ is formed on the end of the ordinary brake
rod, operated in the usual manner by a handle or other means. The end of this
rod is formed with a cross spindle projecting at each side, and on each half of the
spindle is fitted a revolving cone turning on ball bearings, which permit it to
revolve easily. These cones are formed with concave sides, so that together they
form a roller having a deep groove of approximately semicircular form, each half
of the roller being capable of turning independently. These cones are fitted on
the spindle by a nut and a spring which permits of a side motion, without
interfering with the revolution.
This arrangement adapts itself to the tyre, and if the wheel is out of truth, this
deviation is allowed for by the side play given to the cones. This form of brake
can be made very light and of good appearance.

We, ROBERT POWELL, Cycle Manufacturer, and HENRY CHARLES POWELL,
Cycle Manufacturer both of Abergavenny, 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 :-
This invention relates to a new or improved brake for cycles, especially applicable
for use with pneumatic tyres, and is intended to provide a brake which will not
injure the tyres in any way, while at the same time being thoroughly effective in
controlling the machine.
The end of this rod is

formed with a cross spindle projecting at each side, and on each half of the spindle
is fitted a revolving cone turning on ball bearings, which permit it to revolve
easily. Instead of balls, cone or other bearings may be employed but the balls
are preferred. These cones are formed with concave sides, so that together they
form a roller having a deep groove of approximately semi-circular form, each half
of the roller being capable of turning independently. These cones are fitted on
the spindle by a nut and a spring which permits of a side motion, without
interfering with the revolution.

page_text: This arrangement adapts itself to the tyre, and if the wheel is out of truth, this
deviation is allowed for by the side play given to the cones.
This form of brake
can be made very light, and of good appearance.
In order that this invention may be more clearly understood reference is had to
the accompanying sheet of drawings, in which
Fig. 1, is a section through the brake, Fig. 2 is an elevation of the same and
Fig. 3 shows in section one half of the brake when moved slightly to one side.
The end a of the brake rod A is in the form of a boss with a cross spindle B
projecting at each side for a short distance. This spindle serves to carry the
brake formed of two cones C one on each side, these cones being formed with
curved or concave sides so as to form a deep circular channel when fitted together
as shown in Figs. 1 and 2. These cones are mounted on the spindle B by means
of the two sets of balls D and D' which permit them to revolve freely. The
balls D are placed at the inner side of the cone and bear against the boss a, the
other set being fitted outside these and secured in place by the nut b. The cone
is fitted on the spindle B by means of the nut b and the spring 1, the nut adjusting
the pressure of the spring to the required degree. This spring bears upon the
nut b and thus keeps the cone in place, but at the same time allows it to slide on
the spindle, when any side pressure is applied owing to the cycle wheel being out of
truth or from any other reason. This side play is shown in Fig. 3 and to prevent
any danger of the set of balls D escaping, the inner end of the cone forms a lip
extending over the side of the boss a.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed I declare that what 1
claim is :-
(1) An improved brake for cycles consisting of two cones with curved sides,
mounted on a cross spindle fitted to the end of the brake rod, provided with
springs keeping them in position and adapted to move transversely under pressure
as well as to revolve, substantially as and for the purposes specified.
(2) In an improved brake for cycles the combination of a cross spindle fitted on
the end of the brake rod with two cones having curved sides turning on the side
of the spindle, uuts at each end of the spindle with springs bearing against the
cones and retaining them in position, at the same time permitting of a slight
transverse movement, substantially as described and for the purposes specified.
(3) In an improved brake for cycles the combination of a brake rod with a boss
at its end, and a cross spindle at each side, of two cones with curved sides turning
on ball bearings on the side spindles, springs on the spindles retaining the cones in
position and nuts at each end for adjusting the pressure of the springs, substantially
as described and for the purposes specified.
(4) The improved brake for cycles, constructed and operating, substantially in
the manner described and shown and for the purposes specified.
