Title: Electromagnetic pattern selector for an embroidery machine
IPC: D05C7/08
Filed: 1982-01-15
Abstract: A positioning device for a mechanical switching lever arrangement in an embroidery machine comprises an electromagnetic device which serves for displacing a pawl lever between a first end position and an intermediate position. The pawl lever serves for actuating a switching lever arrangement. The positioning device further comprises a mechanical amplifier device for displacing the pawl lever between the aforementioned intermediate position and a second end position. At its free end region the pawl lever carries a permanent magnet which continuously adheres to the electromagnet when the same is deenergized. The mechanical amplifier device, which cooperates with the pawl lever, comprises an externally actuatable switching lever arrangement. By pivoting this switching lever arrangement the pawl lever can be displaced from its intermediate position to the second end position and vice versa. In this way there can be initiated, at first, a displacement operation, by means of a relatively small arrangement of magnets, whereupon the actual positioning or adjustment work is carried out exclusively by means of the mechanical amplifier.
