I, ROBERT LINGARD, of 48, Mason Street, Swan Street, Manchester, Mechanical
Engineer, do hereby declare the nature of this invention to be as follows:-
My said invention relates to an improved construction of brake for use on
bicycles tricycles and similar vehicles.
According to my said invention I apply to one of the shafts or axles of the
vehicle or to the hub of one of the wheels a brake pulley or wheel having a flanged
or projecting periphery or rim against the internal and external surfaces of which
act the brake blocks or brake shoes. The internal and external brake blocks are
connected together by means of a lever or levers in such a manner that when it
is intended to apply the brake the brake shoes simultaneously approach and nip
the rim of the brake pulley.
The brake is operated by a lever or other handle and a link extending therefrom
to the lever which operates the brake shoes.
A spring or springs is or are provided for automatically releasing the nip of the
brake when it is desired to put the brake out of action.
In some cases a detent or detents is or are provided for keeping the brake con-
tinuously in action as for example when descending a long hill.

Improvements in or applicable to Brakes for Cycles.
I, ROBERT LINGARD, of 48, Mason Street, Swan Street, Manchester, Mechanical
Engineer, 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:-
My said invention relates to an improved construction of brake for use on
bicycles tricycles and similar vehicles.
According to my said invention I apply to one of the shafts or axles of the
vehicle or to the hub of one of the wheels a brake pulley or wheel having a flanged
projecting periphery or rim against the internal and external surfaces of which
act the brake blocks or brake shoes.
In order that my said invention may be more clearly understood I will describe
the same with reference to the accompanying drawings in which

page_text: Fig. 1 is a side elevation showing the brake as applied to the driving shaft of
a bicycle.
Fig. 2 is a front elevation as seen in the direction of the arrow y of Fig. 1.
Fig. 3 illustrates the brake pulley and brake shoes as seen from the back of
Fig. 1.
In these figures a is the frame of a bicycle. To the driving shaft 6 carrying
the chain wheel c and cranks d I apply a brake pulley or wheel e having a flanged
or projecting periphery or rim f against the internal and external surfaces of
which the brake blocks or brake shoes g g¹ act. These brake shoes g g₁ are con-
nected together by means of a lever having its fulcrum at i in a bridge or
bracket on the cycle frame.
When the brake is applied the opposed brake shoes simultaneously approach
and nip the rim of the brake pulley.
A spring connected to the lever presses the lower end of the lever against
the stop and keeps the brake shoes g g¹ out of contact with the brake pulley e
when not required.
Secured to the lever h is a cord m passing through a hole in the end of a foot
lever P and having an enlargement or knot m¹ formed thereon.
The brake may be operated either by pressure on the foot lever p or by means
of a lever or other handle connected to the cord m at or near the handle bar of the
cycle. In lieu of a cord any other suitable rigid or flexible link or connection
may be used to operate the brake.
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. A cycle brake consisting of a brake pulley e in combination with opposed
brake blocks or brake shoes g g acting simultaneously on the internal and external
surfaces of the rim of the brake pulley substantially as set forth and shown.
