Abstract

763,407. Selective printing or embossing. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 4, 1954 [Oct. 7, 1953], No. 28495/54. Class 100(4) In an apparatus of the type in which a character is formed by the relative movement between the ends of a group of wires, the wires 20 are held in a group and movable towards and away from a recording material so that the selectively displaced wires undergo impact with the recording material to effect printing impression, perforation or embossing. As shown the wires 20, in their flexible tubes 22, are held by a clamping screw 105 in a printing head 24 vertically slidable on studs 108 fixed on a member 106 which is slidable transverse of the record material 14 so the printing head 24 may be dispersed in different printing positions with respect to the record 14. The head 24 is moved to effect impression by a flexible drive wire 128 actuated by a cam mechanism 148, 150, and a lever 132, whose action is adjustable by the device 138, 140, 142, 144. The setting of the wires 20 is under the control of electromagnets A-F and a longitudinally and rotatively settable control bar 32, in a manner described in Specification 729,064. The control bar 32 is moved to set the wires by the action of cams 60, 61 on a frame 30 and restoration is by a bail 84, controlled by a cam 94 so that it moves rightwardly with the setting action, so as to prevent overthrow, and leftwardly after printing, to restore the wires to original position. Movement of each print wire is at all times limited and stabilized by heavy slugs 74 slidably carried in a fixed guide housing 26.
