Improvements in or connected with Brake for Cycles Worked by
the Steering Rod.
I, PAUL BAUMERT Engineer of 26 Kurfürstendamm, Berlin, in the Kingdom of
Prussia, Germany, 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 :-
The subject of the present invention shows a cycle-brake set in operation by
means of the steering-rod, its essential feature being that the brake acts by means
of a steel wire inside the rod in question. The cycle brake is represented in the
accompanying drawing:
Fig. 1 is the brake in longitudinal plan.
Fig. 2 a sectional drawing through both steering arms in connection with the
steering rod.
Fig. 3 a front view of both steering arms in connection with the steering rod.
In the lower part e of the framework R (Fig. 1) the pin C is drawn upwards
and presses the brake block B against the tyre A, the lever D being firmly fixed
in the support E. The pin is provided below with a plate c' upon which the
spring t rests and by which means the latter can always draw the pin back again
into the normal position when the brake is not applied. The upper end of the
pin C is provided with an eyelet p, through which a steel wire G is drawn and
made fast. The steel wire (a steel piano string is most suited) passes through the
steering rod N over a roller v (Figs. 1 and 2) as far as the T piece M (Figs. 1, 2,
and 3).
In the T piece M lies a shaft W, and to both its ends are attached the steering
arms K.
The shaft W is cut away in the middle to exactly one half and so wide
that two screws and z¹ can be comfortably introduced. These screws serve to
press the piece S (Fig. 1) which fits exactly into the hollowed out part, against the
surface of the shaft W. Round the shaft. W runs a deep groove which receives
the steel wire G and prevents contact with the T piece M. Upon the surface
obtained by the hollowed out part S runs a deep groove further. It is however so
hollowed out that the steel wire G in its continuation to G is held fast in its
position by the surface of the inserted piece S on tightening the screws ==¹.
If the steering arms K K are pressed downwards, the shaft W attached to the
steering arm is turned and the steel wire G drawn upwards together with the
pin C, by which means the brake comes into play.
The screws pass so far through the T piece M that they first lie with
the extended head part against the opening a (Figs. 1 and 2) in order to limit the
length of movement of the steering arms and brake and further, by means of the
lock L (Figs. 1 and 3) to set the brake out of action. This is effected by clapping
the lock Lover the screws z z¹. As a consequence the steel wire G is continued
to G'in order that by shifting the steering arms the wire can likewise be shortened
or lengthened. To do this the screws z z¹ are loosened and the end of the wire G'
attached to the piece O (Fig. 1) by means of the eyelet O' taken out and then let
out or tightened.
Having now particularly described and ascertained the nature of my said inveo-
tion and in what manner the same is to be performed, I declare, that what 1
5 claim is:
A ovalo krake characterised be a wire & Icing inside the steering rod N and

page_text: working the brake B by a wire attached to the shaft W, but capable of being
adjusted, which is drawn upon by turning this shaft, whereby the wire is compelled
by means of a roller to remain in the centre of the steering rod and the free end
of the wire G³ can be taken out for adjustment of the steering rod through the
agency of an eyelet O' attached to the closing head O.
