page_text: I, PAUL DORIGNY, of 105, Rue Beaubourg, Paris, in the Republic of France,
Merchant, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in brakes for velocipedes.
According to this invention the brake is operated by means of a lever pivoted to
the handle bar within reach of one hand of the cyclist. A series of rods running
along the frame and pivoted to cranked levers transmits the movement of the said
lever to a band brake which acts on a pulley fixed to the driving wheel.
In carrying out my invention I pivot the lever to a collar fixed to the handle bar.
A rod is attached at one end by means of a universal joint to the end of the said
lever and at the other end to a flange pivoted to a fixed collar. The flange
surrounds the tubular steering head without however touching it and is provided
with an arm to the free end of which a rod is connected, the said rod being
connected at its other end near the pedal to a cranked lever pivoted to a support
preferably in the form of a collar fixed to the saddle standard or frame strut.
The other arm of the cranked lever is connected to one end of a rod which is
pivoted at its other end to a short lever carried by a support. This lever is
connected by means of a short rod to a lug on the end of the brake band.
The brake consists of a steel band to which a band of leather is riveted, the said
band being wound spirally on the inside of a fixed drum to which one end of the leather
spiral is fixed. When the operating lever is raised the free end of the band of the
brake is pulled by the rods so as to apply the brake band to a pulley on the boss
of the driving wheel.
When the lever is released the brake returns to its original position owing to
the elasticity of the steel band.

I, PAUL DORIGNY, of 105, Rue Beaubourg, Paris, in the Republic of France,
Merchant, do bereby 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 improvements in brakes for velocipedes.
According to this invention the brake is operated by means of a lever pivoted
to the handle bar within reach of one, hand of the cyclist. A series of rods
running along the frame and pivoted to cranked levers transmits the movement.

wheel.
To enable my invention to be fully understood I will describe it by reference to
the accompanying drawing, in which :-
Figure 1 is a side elevation of a bicycle having my improvements applied
thereto.
Figure 2 is a front view of a part of the same.
In carrying out my invention I pivot the lever A to a collar b fixed to the handle
bar. A rod c is attached at one end by means of a universal joint to the end of
the said lever A and at the other end to a flange d pivoted at e to a fixed collar B.
The flange d surrounds the tubular steering head Ċ without, however, touching it
and is provided with an arm f to the free end of which a rod g is connected, the
said rod g being connected at its other end near the pedal to a cranked lever h
pivoted to a support i preferably in the form of a collar fixed to the saddle standard
or frame strut.
The other arm of the cranked lever h is connected to one end of a rod; which
is pivoted at its other end to a short lever k carried by a support or bracket c. This
lever is connected by means of a short rod to a lug m on the end of the brake
band.
The brake (shewn in side elevation and sectional plan in Figures 3 and 4
respectively) consists of a steel band n to which a band o of leather is riveted, the
said band o being wound spirally on the inside of a fixed drum p to which one end
of the leather spiral is fixed. When the operating lever A is raised the free
end m of the band of the brake is pulled by the rods so as to apply the brake
band to a pulley T on the boss of the driving wheel.
When the lever A is released the brake returns to its original position owing
to the elasticity of the steel band n.
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 I
claim is :-
1. A brake for velocipedes having a combination of rods and cranked levers
arranged on the frame of the machine, and a brake band adapted to be tightened
on a drum, mounted on the axle of the driving wheel, by means of a lever, placed
within reach of one hand of the cyclist, and of a flange, encircling the steering
head without touching it through the medium of the rods and cranked levers for
the purpose of enabling the brake to be applied in any position of the handle bar,
substantially as described and illustrated.
2. The improvements in breaks for velocipedes hereinbefore described and
illustrated in the accompanying drawing.
