摘要： A linespacing apparatus includes a slip clutch assembly which is driven by an electric motor. The slip clutch assembly includes a face cam which drives a linkage which, in turn, indexes a platen in order to linespace the platen. The face cam includes an abutment portion which abruptly halts the motion of the linkage and the slip clutch assembly prevents bounce or recoil of the linkage thereby promoting smooth operation of the apparatus. The linkage may be adjusted by an operator to vary the amount of rotation of the platen during each operating stroke of the linkage.

摘要： A keylever touch control mechanism for typewriters includes keylevers mounted on a common pivot which spans the distance between the spaced side frames of the typewriter. The keylevers are supported in their rest position by a plurality of underlying leaf springs. Keylever touch is controlled by the amount of force exerted on the underside of the keylevers by the leaf springs. A spring loaded pivotal bail having rigid extensions underlying the leaf springs pivots into abutment with the springs to vary the tension of the springs. A detented control mechanism is coupled to the bail to pivot the bail extensions into and out of abutment with the leaf springs. When the bail extensions are pivoted into abutment with the leaf springs and a keylever is depressed, the force required to overcome the biasing force of the spring loaded bail extensions to depress a keylever is increased and the keylever touch is correspondingly increased.When the bail extensions are pivoted out of abutment with the leaf springs and a keylever is depressed, the leaf springs are deflected independent of the bail extensions and therefore the force required to depress a keylever is decreased and the keylever touch is correspondingly decreased.
摘要翻译：用于打字机的键盘式触摸控制机构包括安装在公共枢轴上的键盘，其跨越打字机的间隔开的侧框架之间的距离。钥匙扣通过多个下面的板簧支撑在它们的休息位置。键盘触摸受到板簧施加在钥匙圈下侧的力的控制。具有弹簧下方的刚性延伸部的弹簧加载的枢转吊环枢转成与弹簧邻接以改变弹簧的张力。一个止动控制机构与吊环相耦合，以将吊环延伸部枢转到与板簧相接触和离开的位置。当吊环延伸部枢转成与板簧相接触并且键盘被压下时，克服弹簧加载的吊环延伸部的偏压力以压下钥匙圈所需的力增加，并且键盘触摸相应地增加。

摘要： An interposer in a typing machine key action is supported by an arcuate spring and a shelf. When a key lever bears against the arcuate spring to release the interposer from the shelf, the arcuate spring snaps the interposer against a pawl that engages a power roll to initiate a typing operation. Potential energy is restored to the arcuate spring as the key lever lifts the interposer back to rest position. The arcuate spring serves as a support and frictionless pivot for the interposer and biases the interposer against the shelf while providing energy to impel the interposer against the pawl.

摘要： A typebar support for low cost typewriters includes an arcuate segment supported on a frame where a plurality of typebars are pivotally mounted. The free ends of the typebars are supported by an arcuate support. The support is rockably suspended on the frame by a pair of arms extending from the ends of the support to the frame. The arms are biased upward by a pair of springs and limited in its upward movement by an abutment mounted on the segment. As a typebar returns to rest after a print cycle has been completed, the energy accumulated in the typebar during flight is partially dissipated when it impacts on a yieldable pad on the typebar receiving edge of the support. The remaining energy is absorbed by the rocking motion of the support. The energy dissipation by the yieldable pad combined with the energy absorption by the rockable support results in a typebar support that effectively reduces typebar rebound and the accompanying problems.

摘要： A character display is pivotably mounted on an electronic typewriter for pivotable movement from an open position for viewing the character display to a closed position for covering the keyboard. The character display has a pivot axis in alignment with a rotatable axis of the platen. A structure for pivotably mounting the character display includes a spring operable to dampen the pivotable movement of the character display near the closed position. A brake pad combined with the dampening spring holds the character display in manually selected positions near the open position. A paper support which covers a platen and an adjacent open area is combined with the character display located in the closed position to provide a cover for the typewriter.

摘要： A single solenoid is connected to a ribbon feed mechanism which is selectively operable either to feed a print ribbon or to lift and feed an error correction tape. A print hammer solenoid is operable to condition the ribbon feed mechanism either for feeding the print ribbon or lifting and feeding the error correction tape. To feed the print ribbon, an electronic circuit energizes the print hammer solenoid before energizing the ribbon feed solenoid in response to depressing a character key. To lift and feed the error correction tape, the electronic circuit energizes the print hammer solenoid after energizing the ribbon feed solenoid in response to depressing a correction key.

摘要： A printing device having a detachable printwheel coupling means which includes a motor driven drive plate which is formed with a cantilevered spring finger and an aligning slot disposed on the side opposite the spring finger. The spring finger carries at its free end an alignment pin which automatically engages a radially offset cam surface located in a recess formed in the hub of a printwheel when the drive plate rotates relative to the printwheel. The printwheel hub also includes a drive pin which engages the aligning slot when the printwheel and drive plate abut under the urging of a pressure plate. The device inhibits angular and radial movement between the drive plate and the printwheel.

摘要： The present invention includes means for maintaining a printing element in its home position without any accompanying noise and for thereafter moving the carrier to its left margin position after the power switch is turned on. A latch member controlled by an actuator engages a notch in a flange of a rotating printing element drive gear for establishing the home position of the printing element. When the latch member engages the flange, the printing element drive gear motor is deenergized, stopping rotation of the drive gear, and the noise which would otherwise be caused by the print element drive motor continuously trying to rotate against the latch member is eliminated.
