摘要： A keyboard spacer for inhibiting the depression of selected push buttons upon a keyboard is shown including a longitudinal trunk having a first resilient arm which engages a key stem of a keyboard switch between the switch and the push button. As the first resilient arm yields, a second latching arm snaps over the key stem for retaining the spacer in the position desired. The spacer, which inhibits the depression of the push button, may be easily removed if push button operation is desired.

摘要： A keyboard of a typewriter comprises a common actuator biased by a spring. The depression of a key causes a corresponding intermediate member to engage with the actuator to initiate an operating cycle and to move the intermediate member to a position which causes selection of an operation corresponding to the key which has been depressed. The engagement of the common actuator with more than one intermediate member consequent upon depression of more than one key causes the common actuator to move under the spring bias at a substantially reduced speed and a locking mechanism to lock selected operations. A reloading mechanism is responsive to the speed of the actuator for unlocking the locking mechanism and restoring the actuator and the intermediate member when the reduced speed is sensed.
摘要翻译：打字机的键盘包括由弹簧偏置的公共致动器。键的按压使得相应的中间构件与致动器接合以启动操作循环并且将中间构件移动到导致选择对应于已经被按下的键的操作的位置。普通执行器与多于一个中间构件的接合是由于按压多于一个键导致公共致动器以大大降低的速度在弹簧偏压下移动，并且锁定机构锁定所选择的操作。当感测到降低的速度时，重新加载机构响应于致动器的速度来解锁锁定机构并恢复致动器和中间构件。

摘要： An electric typewriter having a prevention mechanism for preventing printing errors caused by a depression of a few keys in very rapid succession. The prevention mechanism includes a lock member for locking a clutch, which is interposed between a drive motor and a printing mechanism, in a disengaged condition. The lock member is normally held in a non-operational position for allowing the clutch to be engaged, and is moved in response to a special operation of a sensing member to an operational position for keeping the clutch in a disengaged condition. The sensing member is so disposed as to be moved in a distinct way different from the normal operation mode when a few keys have been depressed in very rapid succession.

摘要： Apparatus for controlling type printing sequences of manually actuatable, power-driven typwriters and similar machines having type printing mechanisms and key levers, including a plurality of releasably mounted intermediate members, each of which is movable between a rest mode and a release mode and arranged to actuate an associated type printing mechanism when its respective key lever is depressed. Each intermediate member has a spring member biasing it toward a ball block, into which one released member at a time may drop. When an intermediate member is released while another intermediate member is in the ball block, the biasing force of the released intermediate member supplied by its spring member holds it in storage until the ball block is cleared.

摘要： A coded electric signal generating keyboard for a single element typewriter is disclosed which has a keylever signal storing function and includes an interlock mechanism for permitting only one interposer at a time to be moved out of its normal position. Thus after depression of a particular key another key is prevented from being depressed until the interposer moved to an operative position is restored to the normal position during an initial part of a printing cycle initiated in response to depression of the particular key. It further includes an arresting mechanism operable to arrest another subsequently released interposer to an intermediate stored position during the remaining part of the printing cycle whereby another printing cycle may be initiated at the end of such printing cycle.

摘要： High speed printing machine incorporating a pressure-sensitive transfer ribbon of the squeeze-out or reusable type having a thin, flexible plastic film foundation having bonded thereto a microporous resinous ink layer containing pressure-exudable liquid ink which is adapted to be pressure-transferred to a copy sheet by means of a printing element which makes momentary impression contact with the ribbon while the ribbon is moving slowly across the path of said printing element. The invention comprises a high speed printing or impact machine which includes means for the application of a thin friction-reducing or slip-permitting film of liquid silicone oil to the rear or impact surface of the transfer ribbon in order to reduce the friction between the printing element and the moving transfer ribbon and to prevent grabbing of the film foundation and breakdown of the bond between the film foundation and the ink layer.
