Abstract
Abstract Bicycle brake actuator for drop type handle bars, such as are employed on lightweight touring types of bicycles. The brake actuator includes a main hand brake lever operable when the hands are on the hand grips of the handle bars, and an auxiliary brake lever movable relative to the main brake lever and operable by the hands when on the cross bar of the handle bar. In one form of the invention, either hand brake lever may be operated without affecting operation of the other lever. In another form of the invention, the main hand brake lever and auxiliary hand brake lever operate together when applying the brakes by the main hand brake lever and application of the brakes by the auxiliary hand brake lever has no affect on movement of the main hand brake lever.

Claim 4
Dependent Claim
274 words
In a device for applying the brakes of a bicycle to the rim of a bicycle wheel, and in combination with a bicycle handle bar having a straight cross bar, downwardly curved sections forming continuations of the ends of said cross bar and terminating into generally horizontally extending drop type hand grips, a brake lever housing, a clamp clamping said housing to the downwardly curved section of the handle bar and including a strap extending about the handle bar, a mounting bar within said housing and connected therewith, and means connected between said mounting bar and strap, clamping said strap to the handle bar, a main brake lever transversely pivoted to said mounting bar and positioned thereby in accessible relation relative to the hand grip of the handle bar, an auxiliary brake lever pivotally mounted on said mounting bar and positioned thereby in accessible relation relative to the cross bar of the handle bar, an abutment member mounted on said main brake lever and extending inwardly therefrom within said housing toward said mounting bar and having a downwardly opening slot therein, a flexible cable extending through said slot and having a connector on the free end thereof and adapted to be connected to a lever of the bicycle brake, a casing extending from said housing along said cable and adapted to be connected to a second lever of a bicycle brake, means operated by one hand brake lever for moving said cable relative to said housing through said abutment to apply the brake, and means operated by the other brake lever for applying the brakes independently of said first brake lever and said abutment.
Claim 5
Dependent Claim
91 words
The bicycle brake operating device of claim 1, wherein said main and auxiliary brake levers are transversely pivoted to said mounting bar in spaced relation with respect to each other, wherein one brake lever applies the brakes directly through said abutment and flexible cable, and wherein the other brake lever has engagement with the end of said casing, and exerts a compressive force thereon, flexing the casing to move laterally and exert a brake applying force on the cable upon movement of the auxiliary hand brake lever towards the handle bar.
