Abstract
A closure cover for the opening in the base of a sewing machine which provides access to the thread control members for the lower hook. The cover is carried on a rod which is vertically slidable and rotatably carried in the base and includes a combined spring biased locking and release arrangement the first of which maintains the cover in operating position on the base, and the second which releases the cover. Upon release the cover is automatically raised by a spring member and can be pivoted to a position to facilitate access to the members within the opening.
