Abstract

The pressure foot of the sewing machine is lifted by a member moving parallel to it, and interlocked by a cam plate, which is driven by the arm shaft, when the latter is resting, and the needle is at a pre-determined position. The lifting member may be brought into a working position independent from the shaft. The cam plate controls a ratchet, which is maintained in its working position by a spring, and which forms the interlocking unit for the foot. The cam plate is used as a control member for the interlocking units only.
