Abstract

A device for temporarily interrupting the movement of the embroidery needle on an automatically controlled embroidery or sewing machine has at least one needle driven by a connecting rod and a crank from a drive shaft. On this needle bar there is fastened a driver which can be coupled via a shift pawl developed as double-armed lever with a drive carriage which is pivotally connected to the connecting rod. While one arm of said lever cooperates with a catch developed on the drive carriage, another arm of the lever cooperates with a controllable holding pawl by which the needle bar can be held fast in an upper dead-center position with simultaneous disconnection from the drive carriage. In order to relieve the actuating element of the holding pawl from forces of the shift pawl and be able to transfer the holding pawl within a very short time from an active position into a disengaged position, the holding pawl is held in a form-interlocked manner against the forces of the shift pawl and can be moved out of the plane of motion of the shift pawl. Such movement can take place out of the plane of motion of the shift pawl.
