Abstract
A stop motion device for stopping the motion of a sewing, embroidering or tufting machine, comprises a pivotally mounted sensing lever having a sensing arm for receiving threads used by the machine. The sensing lever is also engaged with a switch for deactivating the machine when the lever is pivoted into a position to disengage the switch. A fixedly mounted guide is provided for guiding the threads at a location spaced from the sensing arm in the feed direction for the threads. Either the sensing arm or the guide includes one bore for guiding all the threads while the other includes two offset bores each for receiving at least one thread. The offset bores are offset perpendicularly with respect to the feed direction and with respect to the other single bore. When one of the threads breaks, the tension of the remaining threads causes the sensing lever to pivot and thus activates the switch to stop the machine.
