Brake positioning system
First Claim
Patent Images
1. A woodworking machine comprising:
- a blade;
a detection system adapted to detect a dangerous condition between a person and the blade;
a mounting pin;
a brake supported by the mounting pin, where the brake is adapted to decelerate the blade in response to detection of the dangerous condition; and
a brake positioning system configured to pivot the brake on the mounting pin to selectively position the brake relative to the blade without activating the brake to decelerate the blade;
where the blade is planar and where the brake positioning system is configured to pivot the brake around an axis perpendicular to the plane of the blade.

Abstract
A saw is disclosed having a detection system adapted to detect a dangerous condition between a person and a saw blade, and a brake adapted to stop the saw blade in response to detection of the dangerous condition. The saw further includes a brake positioning system that allows the brake to be positioned in at least two different operable positions to accommodate at least two different blade diameters. The saw may include a system to detect brake-to-blade spacing.
