Abstract: A set of selectively active stop pins cooperate with measured openings in a control plate to limit letter feed motion in either the forward or reverse direction. The measuring plate opening includes two effective portions that are alternately selectable to provide two different measuring calibrations. A preferred alternate calibration is known in the art as ''''EXPAND'''' where all measurements are increased by a fixed amount. Fixed increment spacing is obtained by suppressing the measuring pin selection through an override device, thereby allowing control to be accomplished by a normally active measuring pin in cooperation with the measuring plate. By providing all measuring mode control at the measuring plate, it becomes unnecessary to modify the space control information generated in the typewriter keyboard.

Abstract: 1,254,639. Typewriters &c. INTERNATIONAL BUSINESS MACHINES CORP. 25 June, 1969 [15 July, 1968], No. 32190/69. Heading B6F. An encoding keyboard, comprises a plurality of keys operating a plurality of control members 64, 72 movable from non-select to select position by drive shaft 40 and which have an interlocking device (15) as described in Specification 976,473, one of the keys 60 is interconnected with an auxiliary lever 70 so that it works in opposite direction to the lever key 60, i.e. when key 60 is depressed the lever 70 is raised and when released the lever 70 is depressed. Magnetic reed switches operated by the presence of a pivoted shunt 17 or shunt 92 accurately signal the status of the keyboard. Operation of the auxiliary key 60 causes actuation of control member 64 and the end of a horizontal arm 82 of a transfer link is moved forwardly. An upstanding part 84 co-operatively engages an inclined camming bracket 74 attached to the auxiliary lever 70 which is thereby raised against the pull of bias spring 73. Release of the key lever 60 causes opposite effect and lever 70 is depressed, but this time a dobber 71 engages the actuator 72 which is thereby pushed into engagement with the drive shaft 40 and the appropriate signal is given by the magnetic switch 19.

Abstract: 1,192,425. Typewriters, &c. INTERNATIONAL BUSINESS MACHINES CORP. 1 Aug., 1967 [19 Sept., 1966], No. 35209/67. Addition to 1,187,507. Heading B6F. In a selective printing machine wherein the letter spacing effected by the escapement mechanism varies with the character selected a "noprint" device is provided which when operated by a translator in conjunction with a character selection prevents printing of the character but allows operation of the escapement to effect spacing corresponding to the selected character e.g. for justifiable purposes a variable spacing between printed characters can thus be obtained. As shown, a settable printing-head 16 Fig. 2, is mounted on a carriage 18 which is moved by a lead screw 26 for letter spacing. The escapement is controlled, as described in Specification 1,053,186, by a pin wheel 27 and a pin-setting assembly 28 connected by links 29 to bails 52, Fig. 3, operated by coded projections on an interposer 37 associated with a character key-lever 30 and moved lengthwise by a cyclically-driven shaft 44. Coded projections 46 on the lower edge of the interposer operate bails 47 to effect character selection 6 then projections such as 54, Fig. 3, operate bails such as 56, 58, Figs. 2, 3, controlling the stroke of a cam follower 76, Fig. 2, which in turn controls the impression velocity of the type-head 16 as described in Specification 1,187,507. Impression is effected by the engagement of a cam 94 with a roller 91. The cam 94 has axially-spaced parts, and according to which part is engaged by the roller 91, a high, medium or low velocity is imparted to the head 16. The roller 91 is selectively moved into alignment with one of the cam parts according to the stroke of follower 76 which affects the position of a pulley 87 around which passes a band 87 1 to which the roller 91 is attached. Also, as described in Specification 1,187,507, a manually-operated "no-print" key 24, Fig. 2, is provided, which when depressed allows movement of follower 76 such that roller 91 is positioned for engagement by a part 93 of cam 94 designed so that the head 16 does not make a printing stroke. Thus, if key 24 is operated in conjunction with a character key, a spacing movement of the carriage corresponding to the character is effected without printing. Operation of the machine can be controlled by signals from a data processor which receives unjustified data from tape input devices and manipulates this data in accordance with a stored justification programme. Seven signals can issue from the data processor, each signal actuating an electromagnet 107. . . 113 of which magnets 107 . . . 109 are shown in Fig. 5. One signal is a "no-print" signal which operates electromagnet 113. Associated with each magnet is a code slide 100 ... 106, Fig. 3. As shown in Fig. 5, each slide is normally held in a leftward position against the action of a spring 127 by the engagement of its magnet armature 130 with a lug 132 on the slide. The receipt of one or more signals energizes the corresponding magnets and releases the corresponding slides which move to the right. Coded projections are provided on the lower edges of the slides. Seekers 115, Figs. 3 and 5 urged upwardly and leftwardly by springs 146 have parts extending below and perpendicularly to the slides 100... 106, and there is one seeker for each character and function key except in the case of the "noprint" key 24. The seeker 115 for the "noprint" function is connected by a link 61, Fig. 2, to a key-lever 60 with no key button so that it cannot be depressed manually. The lever 60 is associated with an interposer similar to interposer 37, Fig. 3, which, when driven, does not affect the escapement mechanism. Projections on the lower edge of the "no-print" interposer act to select the character on the home position of the print head The other seekers 115 are connected by linkages 118, 34 to the various key-levers. After the slides 100 ... 106 have been set, a bail 149 controlled by one of a number of cams 121 is permitted to rise, thus allowing a selected seeker to rise into slots in the slides 100 . . . 105, or in the case of a no-print spacing, allowing a selected character seeker and the no-print seeker to rise into slots in slides 100 ... 106. In this position, a bail 156 operated by another cam 121 moves the upwardly displaced seeker or seekers to the right to operate the required keylevers 30, 60 &c to effect the operations already described. Tf a spacing between letters is required other than that provided by the arrangements described, a signal may operate a space bar device settable by a dial in known manner to give the desired spacing.
