摘要： A sewing machine is provided with a needle bar movable substantially vertically and capable of being pivoted laterally about a horizontal axis, a crank mechanism for operating the needle bar connected to a drive shaft, a thread hooking means beneath the needle bar, a shuttle mechanism operable in conjunction with the needle bar to form a stitch, and a reciprocable cloth feeding means in which lateral pivoting of the needle bar and/or the feeding movements effected by the cloth feeding means is or are produced by a code converter for converting a variable binary code to mechanically controlled movements determined by setting means and drive means arranged in the converter.

摘要： The instant invention concerns a sewing machine having electromagnetic control elements for swinging out the needle-rod sideways and/or accomplishing the forward movements of the fabric slider, which control elements being activated by means of electrical signals vary the thickness of a packet of plates which in turn vary the displacement of the needle-rod sideways.

摘要： A converter for converting binary codes into mechanically controlled movements which contains adjustment means which by means of an outside signal source is given a special adjustment for each code, a plurality of sets of cam discs, mounted and axially displaceable on a common shaft and adjustable individually with respect to a zero position of the adjustment means, each set of cam discs is disposed with axial cams facing one another, and stopping means and entrainers cooperating with the adjustment means, and that a converter drive system comprises an axial arrangement of the cam disc sets arranged on the common shaft which passes through the converter and on which a cam disc forming part of a pair of cam discs of each set is journalled and driven in an oscillating movement by an indexing mechanism which is driven by rotating means to produce limited relative movements between the discs in the respective cam sets, transformed into axial displacements of the discs relative to the zero position.
