Abstract

1358391 Linear electric motors TELETYPE CORP 27 May 1971 [28 May 1970 (2)] 17453/71 Heading H2A [Also in Divisions B6 and G4] Type selecting means for positioning a frame 18 carrying types 22 with respect to a print hammer 24 comprises a pair of linear electric motors in the form of coils 50, 52 having perpendicular active coil portions 54, 56 located in a magnetic field between a permanent magnet 30 and a soft iron plate 34 connected by side pieces 40, 46 to a back plate 32 fixed to the magnet 30. The hammer 24 is mounted on a carriage 72 for letter spacing movement by means of a third coil 68. In a modification (Fig. 6), two coils (140, 142) having parallel active coil portions can move in unison or one with respect to the other to position a type frame (18) through a scissors linkage.
