摘要:
A device for deflecting a detached cutting chain off the drive sprocket of a chain saw in order to deenergize and arrest it. A ramp provides a surface disposed below the chain guide bar, which surface is oblique with respect to the chain guide bar, slightly below a lower edge of the chain guide bar and obliquely angled with respect to a plane that contains the exterior surface of the chain guide bar, and distal to the drive sprocket. Sliding engagement of a detached cutting chain with the oblique surface moves the cutting chain exteriorly away from the chain guide bar and off the drive sprocket. A chain catcher is also provided to arrest the detached cutting chain and/or chain shot portions thereof.
