Abstract: A mechanism is disclosed for the automatic erasing of typing errors utilizing a fully serialized and automated correction apparatus where the correction is accomplished by a single backspace operation allowing both the erasure of the erroneously typed letter and the typing of the proper letter. The backspace operation repositions the typewriter carriage for the correction of the erroneous letter and at the same time inhibits the escapement of the carriage for a single print cycle allowing the corrected letter to be printed over the correction without requiring an additional backspace operation. The escapement mechanism is re-engaged during the correction cycle so that the carriage advances of the print cycle.

Abstract: Clearance take-up bias is added to the support structure for a rotatable type element to minimize variations in effective impact force previously induced by the existence of varied amounts of slippage and parts flexure that wasted a portion of the available impact energy.

Abstract: 1,212,928. Typewriters. INTERNATIONAL BUSINESS MACHINES CORP. 2 Dec., 1968 [9 Jan., 1968], No. 57057/68. Heading B6F. In a typewriter in which the letter-spacing may be either one of two different pitches the margin stop mechanism is coupled to the escapement rack so that the stops may be set accordingly. As shown a spherical type-head 12 is mounted for relative movement to a platen 11 and is mounted on a carrier 13 having an escapement pawl 17 co-operating with a double toothed rack 16 and a projection 64 for engagement with a margin stop 41. The teeth 25, 26 on the rack 16 may be set so that one series of teeth co-operates with the pawl 17 by the operation of a letter-space-setting lever 35 having an over dead-centre biasing spring mechanism 30, 32. Movement of the lever 35 is transmitted via linkage 85, 83, 84 so that an elongated bail 81 moves transversely from the position shown in full, to the dotted line position. The bail 81 is positioned below a double toothed rack 42, the teeth 51, 56 corresponding to the two different letter-spaces. Slidably mounted on the rack is the margin stop assembly 41 including a control member 43 and a double pawl 67 with pins 65, 66 for respective engagement with the teeth 51, 56. The pawl is biased into engagement with the respective side of the rack 42 by an overcentre spring mechanism 71 according to the setting of the bail 81. To set the margin stop the control member 43 is pressed inwardly to release the pawl 67 by engagement of pins 99, or 73 according to how the pawl 67 is set and moved sideways to reposition the margin stop assembly 41 on the rack 42.
