hereby declare the nature of this invention to be as follows:-
-
My invention relates to and consists of an improved method of applying a cone
friction brake to the rim of a bicycle such brake being applicable to either the front
wheel or rear wheel the description herein being fully set forth as follows.
The brake lever and brake lever rod is attached to the handles in the ordinary
way.
Attached to the forks of the machine are two supports for carrying two levers,
the levers having their fulcrum on a pin in a slotted projection in the supports.
The lower ends of the levers are angled to which is fitted two grooved wheels
conically bored and having their friction on conical bearings screwed into the
angled levers and secured by a nut.
The grooved wheels having rubber bands fastened in the grooves.
The other ends of the levers terminate in a conical slotted cam which is secured
by a pin or screw on the brake lever rod, the rod passing through the cam.
The cam is slotted on each side so that when the brake lever is pulled to the
handle bar the slotted cam forces open the two levers and brings the rubber covered
wheels on to the rim of the machine.
For applying the brake to the rear wheel the supports which carry the levers are
attached to the back stays of the machine the top ends of the levers are connected
to a bell cranked lever, the bell cranked lever is attached to a rod which passes
through two eyes fixed in the top rail of the machine another bell cranked lever is
fitted to the other end of the rod and terminates in the cam fastened on the brake
lever rod.

CHARLES HENRY RICHARDS, Machinist 53 Military Road Colchester Essex, do
O 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:.
My invention relates to, and consists of an improved method of applying a cone
friction brake to the rim of a bicycle, such brake being applicable to either the
5 front wheel or rear wheel, the description herein being fully set forth as follows:-

page_text: The brake lever, and brake lever rod is attached to the handle in the ordinary
way. Attached to the forks of the machine are two supports for carrying two
levers, the levers having their fulcrum on a pin in a slotted projection in the
supports. The lower ends of the lever are angled, to which is fitted two grooved
wheels conically bored, and having their friction or conical bearings screwed into
the angled lever and secured by a nut; the grooved wheels having rubber bands
fastened in the grooves.
The other ends of the levers terminate in a conical slotted cam which is secured
by a pin, or screw, on the brake lever rod, the rod passing through the cam.
The cam is slotted on each side so that when the brake lever is pulled to the
handle bar, the slotted cam forces open the two levers and brings the rubber-
covered wheels onto the rim of the machine. For applying the brake to the rear
wheel, the supports which carry the levers are attached to the back stays of the
machine. The top ends of the levers are connected to a bell-cranked lever, the
bell-cranked lever is attached to a rod which passes through two eyes fixed in
the top rail of the machine, another bell-cranked lever is fitted to the other end
of the rod, and terminates in the cam fastened on the brake lever rod.
Figure 1 shows the brake lever connected with the handle bar.
Figure 2 is the brake lever rod.
Figure 3 is the supports fixed on the forks of the machine, having their fulcrum
on a pin in a slotted projection.
Figure 4 is the angled levers for carrying two grooved wheels.
Figure 5 is the grooved wheels conically bored.
Figure 6 shows a section of the rubber band in the grooved wheel.
Figure 7 is the conical cam fixed on the brake lever rod, Figure 2.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what I
claim is:-
1. The particular construction of the several parts and their combination, in
the manner shown in the annexed drawings, and their use for the purposes
specified.
2. A conical cam giving lateral motion to two levers having their fulcrum on a
pin in a slotted projection fixed on the forks of the machine.
3. A pair of levers to which are attached two grooved rubber-covered wheels,
for putting friction on the rim of the bicycle.
4. A pair of grooved wheels conically bored, and having rubber bands fixed in
the grooves.
5. A pair of conical studs passing through the two grooved wheels, and screwed
into the angled levers.
Dated this 8th day of July 1897.
