Improvements in or connected with Brake for Cycles Worked by
Means of the Steering Rod
I, PAUL BAUMERT, Engineer of Berlin W., Kurfurstendamm 26, in the Kingdom
of Prussia, Germany, do hereby declare the nature of this invention and
in what manner the same 18 to be performed, to be particularly described and
ascertained in and by the following statement :—
Most bicycle brakes are set in operation by means of a lever passing from the
centre of the steering gear along the right side of the steering aim and ending in
a hand-piece underneath the right handle of the steering arm, the handpiece
being pressed against the stooring arm by the hand, which holds the two at tho
same time.
Every practical cyclist knows the disadvantages of such an arrangement. The
following are the principal disadvantages which make themselves apparent :
Where there are long inclines the hand 18 rendered tired, owing not to the
strain caused by a firm gripping of the brake, but to the exactness with which the
pressure must be exerted in order to apply the brake to that degree allowing of a
descent at the desired rate of speed.
In suddenly stopping the machine in cases of danger from unexpected obstruc-
tious, the fingers, with the exception of the thumb, which remaine upon the steering
arm, must gasp the handpiece of the brake and pull on it with all the power
possible a proceeding which in moments of great danger is very difficult to proporly
carry out.
Strong pulling on the long lever (which is made thin owing to the necessity of
securing lightness), causes it to become bent, aud it must be made straight again
before it will act.
In falls, the hand is very liable to become wedged in between the level of tho
biake and the handle and injured.
The cycle is weighted on only one side by the lever, destroying essentially all
symmetry in external appearance, as it is placed exactly where it is most seen.
These faults are completely avoided in the construction to be described.
The
At the lower end of the fame R, between the fork of the front wheel, and just
over the tyre A, is the brake block B, attached to the lower end of the pin C
apper end of the pin C projects through the plate S into the hollow flame R and
bears at the upper end a head f, between which and the plate S a spital sping t
firmly secures the pin C and the brake block B in the normal position indicated.
ก
The pin Cand the brake block B are pressed downwards against the tyre A
upon the double lever D, which is connected with the pin C and has its fulcrum
and pivot in E, being drawn upwards by means of the rod and G.
The bake od G, which is adjustable in F by means of 0 and P, rests in the
upper lever II, which moves in the direction of a, with the result that a downward
pressure of the steeung arm K or of both steering arms presses the brake block B
against the tyre
By means of the favorable arrangement of levers a light pressure of the
steering arm is sufficient to successfully apply the brake for a length of time with
little or with extreme power and without making the rider tued. Further, one
has always the steering arm in the hand.
In order to allow of the steering arms K being pressed downwards, they can be
turned in the head M of the steering rod N, but only to the extent required by

page_text: the brake Consequently the head M is pierced by two 'slots bb forming the
fulcrums for the lever passing through the steering am K as well as for the
female screw Y.
The externally round female screw Y is formed with four edges towards one end.
This square formation serves for fixing on the femalo screw as well as for discon-
necting the brake. In order to detach the biake it is only necessary to clap the
eyelet L tuning on the support. U, over the female screw Y, as shown in the
drawing The square hole in the eyelet L, which fits exactly over the square
head of the feinale screw Y, serves at the same time for controlling, should the
fernale screw Y of the lever H have become loosened
Before mounting the wheel it is necessary sometimes to disconnect the binke.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, what I claim is .—
1) Cycle brake characterised by the movement of the steering mins K around
their common horizontal axis in such a way that on pressing the arms downwards
by means of a suitable application, a brake B is pressed against the tyre A, whilo
on releasing the pressure upon the steering arms K, the brake B is returned to its
normal position by means of the pressure of the spring t.
2) In the arrangement of a cycle brake shown under Claim 1), the application
of a disconnecting and connecting contrivance for the brake, characterised by a
movable cyclet L attached to the steering rod, the eyelet being clapped on to the
square head Y, for the purpose of preventing a turning of the same.
3) In the cycle brake shown under Claim 1) a method of construction by which
the spring t is arranged in the flame work R.
