Abstract
A brake bar assembly having a U-shaped frame, a sliding friction bar positioned on the U-shaped frame near a closed end of the frame, a fixed friction bar attached to an open end of the U-shaped frame, and a lockable center bar assembly positioned on the U-shaped frame between the sliding friction bar and the fixed friction bar having a spring operated locking mechanism which allows the center bar to be releasably pivoted on the frame.
Claims17
A brake bar comprising;
- a U-shaped frame;
- a sliding friction bar positioned on the U-shaped frame adjacent a closed end of the U-shaped frame;
- a fixed friction bar attached on an open end of the U-shaped frame;
- and
- a lockable center bar assembly positioned on the U-shaped frame between the sliding friction bar and the fixed friction bar.
A rope control device comprising;
- a frame;
- a sliding friction bar attached at one end of the frame;
- a fixed friction bar attached at an opposite end of the frame;
- and
- a center bar having a spring operated locking mechanism which allows the center bar to be releasablely pivoted on the frame.
A method of operating a rope control device having at least three bars wherein the three bars are positioned on a frame and one of the three bars is selectively lockable comprising the steps of:
- depressing a lock release mechanism on the selectively lockable bar;
- moving the selectively lockable bar away from a portion of the frame;
- and
- swinging the selectively lockable bar to an open, unlocked position.
