Abstract

216,037. Smith, A. J. Oct. 2, 1923. Carriage - returning mechanism; l e t t e rspacing mechanism.- A carriage-propelling spring a<1> and a carriage - returning spring b, which is stronger than the spring a<1> and is wound by the operation of the typing - keys, are arranged in co-axial drums a, b<1> adapted to be coupled by a one-way connection on operating a carriage-returning key. The typing-keys may operate a lever c<2> carrying a pawl c engaging a ratchet-wheel c<1> on a worm which drives a worm-wheel e on the drum b<1>. The carriagereturning-key may operate a lever d, adapted to move axially the drum b<1>, thereby disengaging the worm, and causing the drums to engage by means of teeth g thereon. The position to which the carriage is returned may be determined by operating one of a number of carriages-releasing keys; or tabulating-devices may be employed for this purpose.
