Abstract

16,591. Titania Schreibmaschinen Ges. Jan. 20, [Convention date]. Relay actions.-A device for preventing repeated impressions from being made when the keys are held depressed consists of a pawl for each key-lever, adapted on depression of the key-lever to be moved into position for locking the actuating-mechanism; means may also be provided for restraining the pawls so as to permit such repeated impressions to be made when required for purposes such as underscoring. As applied to a machine in which the key-levers d release levers m which are operated by springs q and are returned by the engagement of cams n with a driving-shaft k, the key-levers are connected by slots r and pins s to pawls h which are pivoted at p below the pivots f of the keylevers and are normally clear of the levers m. On depressing a key-lever, the associated lever m is released and the pawl is moved forwards by a spring t into position to catch the lever m on its return and thereby preventing a second operation from occurring. On release of the key-lever, the pawl is moved backwards by the slot r and the lever m is caught by the key-lever. Owing to the relative arrangement of the pivots p, f and the pins s, the key-levers move through a greater arc than the pawls and are thus brought into locking position before the pawls are completely released. The pawls can be prevented from acting, by means of a stop such as a shaft u formed with a flat which normally faces the tails h<1> of the pawls. On rocking the shaft by means of a key v, the shaft engages the tails of the pawls and locks the pawls.
