Abstract
The present invention relates to the braking mechanism of sewing machines and provides a smooth stop motion to halt the machine. The braking phase of the stop motion involves a roller controlled brake pad which slows down the machine prior to the stop dog contacting the stop bolt. The roller, when activated, runs along the right hand stop wheel and verifies the distance of the brake pad from the stop wheel for one revolution. The roller falls into an indentation and is then ejected away from the right hand stop wheel by a notch, thereby descending the brake pad a small distance onto the stop wheel for one more revolution. At this point, the brake attenuates much of the machine's momentum. After one revolution of braking, the machine comes to a smooth stop.
