Abstract

Abstract A caliper brake is mounted on a fork of a bicycle and straddles the peripheral portion of the wheel that is mounted in the fork. In front of the brake a clamp straddles the peripheral portion of the wheel, but is supported by a device that is movable forward and backward relative to the bicycle frame. The clamp normally is disengaged from the wheel. A manually operable device is connected with the clamp for clamping it against the rotating wheel so that the movable supporting device will be moved forward by the wheel. When this occurs, an actuating device operable connecting the supporting device with the brake applies the brake to the wheel with considerable force.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 152 words
In a bicycle having a frame with a fork supported by a wheel rotatably mounted therein, a caliper brake mounted on said fork and straddling the peripheral portion of the wheel, a clamp straddling the peripheral portion of the wheel and normally disengaged from it, a bar extending part way around said wheel and rigidly attached to the frame, a carriage mounted on the bar for movement along it, means connecting said clamp to the carriage, manually operable means connected with the clamp for clamping it against the rotating wheel so that said carriage will be moved forward by the wheel, and a cam bar connected to said carriage and extending toward the brake, the brake having pivoted levers straddling the cam bar, and the cam bar being shaped to spread said levers farther apart to apply the brake to the wheel when the cam bar is moved forward by said carriage.
