We, EDWARD DAVID DITCHFIELD, of 11, Gordon Street, Southport, Lanca-
shire, Mechanic, and GEORGE HENRY BRADLEY, of Kersal Villa, 50, Eastbourne
Road, Birkdale, Lancashire, Cashier, do hereby declare the nature of this
invention to be as follows:-
According to this invention the ordinary cycle brake lever is dispensed with,
and in substitution therefor a small lever is screwed into the centre of a movable
handle bar. The said small lever pierces the handle bar T stamping and works
up and down a slot therein as the handle bar is rotated, and thus operates an
upright brake rod with which it is connected. A smal! conically pointed thumb
screw, which pierces the adverse side of the said T stamping, enables the brake to
be kept applied, or the handle bar made perfectly rigid, at will.

We, EDWARD DAVID DITCHFIELD, of 11, Gordon Street, Southport, Lanca-
shire, Mechanic, and GEORGE HENRY BRADLEY, of Kersal Villa, 50, Eastbourne
Road, Birkdale, Lancashire, Cashier, do hereby declare the nature of this inven-
tion 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 improved means for applying a spoon or similar brake
to the front wheel of a cycle. Hitherto such application has been made by means
of a lever which reaches along the handle bar from the head or drop tube to one
of the handles. According to this invention we dispense with such lever, with its
attendant weight, encumbrance and unsightliness, and we cause the brake to be
applied by a movement of the handle bar itself.
The invention will be better understood upon reference to the accompanying
drawing, in which Figure 1 is a sectional side view of the handle bar, T stamping,
and drop tube of a cycle, constructed according to this invention, Figure 2 being a
sectional plan thereof.
The handle bar shewn in the drawing is made up of two pieces of tubing a a,
the ends of which are brazed or otherwise attached to the ends of a short length
of tubing which is disposed within the T coupling or stamping e so as to be
capable of rotation therein. Passing through a slot d in the stamping cand
screwed into the tube b is a pin e, the inner end of which abuts against the inner
surface of the tube b whilst the outer end is coupled to the end of the brake rod f.

page_text: The pin e and handle bar a therefore form a lever whose fulcrum lies in the
stamping e, and by raising the handles g the bar a a and tube b are slightly
rotated and the pin e depresses the brake rod f and applies the brake. The
return action of the parts may be due to a spring which is fitted to the brake rod.
To form a rigid handle bar the set screw h is screwed into the indenti in the
tube b; and to retain the brake upon the wheel the set screw his screwed into the
indent k, which latter action provides a very effective and hidden cycle lock.
The tubing b may be retained in its place within the stamping e by the screw
threads on the tube and stamping respectively, as shewn; or the surface of the
tube b may be plain and balls may be inserted in a race between the said tube and
stamping; or the tube b may be retained in position by the pin e.
The middle portion of the tube may, instead of being plain and indented or
countersunk as shewn, be serrated lengthways, and the end of the set screw have
loosely rivetted to it a plate which is similarly serrated and disposed in a slot in
the stamping c, for the purpose of locking the handle bar.
Instead of the handle bar consisting of two pieces of tubing connected by a
central piece of tubing, it may be formed of one piece of tubing having a raised
screw thread in the middle.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what
we claim is :-
1. As a means of applying a cycle brake, attaching the brake rod to a pin fitted
in the handle bar, which latter is capable of rotation in its bracket or T stamping,
substantially as herein described.
2. As a means of applying a cycle brake, constructing the handle bar of said
cycle of two pieces of tubing whose ends are brazed or otherwise attached to the
ends of a tube which is capable of rotation in the T stamping of said cycle, and
fitting a pin in said tube which travels in a slot formed in the stamping and is
connected to the end of the brake rod, whereby on raising the handles the handle
bar and tube are rotated and the pin and brake rod are depressed, substantially as
herein described.
3. In combination, a handle bar which is capable of rotation in its bracket or
T stamping, a pin fitted radially in said bar and adapted to depress the brake rod
when the bandles are raised, and a set-screw adapted to enter indents or
countersinks in said bar and lock the bar, substantially as and for the purposes
herein described.
