Abstract
A latch mechanism for a sewing machine bed extension including a spring biased latch button contained on the surface of the bed extension. The latch button actuates one extremity of a pivotally mounted lever having a tang at the locking extremity. The bed extension has a guide stud which engages an aperture in the base of the sewing machine. The tang passes through the guide stud to lock the bed extension to the base. The bed extension may be removed from the base by actuation of the latch button which causes the tang to disengage from the base.
