Improvements in a device for coupling a disk typeholders engine selection of a typewriter

摘要

The device comprises a flange (14) which is fixed to the shaft (12) of the motor and which is provided on its front face with a plurality of radial teeth (28) spaced by recesses each having their active side surfaces parallel to each other and to the radial line through the recess. Removably connected to the character-carrying disc (11) coaxially therewith is another disc (35) of smaller diameter which is provided on its outward front surface with radial teeth (48) having their active side surfaces (50) parallel to each other and capable of being coupled to the radial recesses of the flange which is fixed to the motor shaft. On the other front surface, hooks (38, 39) engage in holes (21, 23) in the disc. In an alternative embodiment the teeth (48) are integral with the hub (16) of the disc (11) itself.
