Abstract

1,079,558. Selective printing. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 12, 1965 [July 25, 1964], No. 29384/65. Heading B6F. Hammer mechanism.-In a printer having a hammer in each character position along a printing line, the hammers 11 are each resiliently mounted upon a pair of leaf-springs 12, 13 and cocked by an electromagnet coil 21 common to magnets in all character positions, actuation of selected hammers 11 being effected by energization of individual opposing electromagnet windings 24, 25 which thus allows these hammers to operate by spring tension. The cocking by the electromagnets is effected in conjunction with a cam which cyclicly moves all the magnets away from the platen and the magnets flexing all the hammers. The magnets are H-shape, the base of the H being directed to the platen while the top is adjustably secured on to mounting block 37. Pairs of clamps 39, Fig. 7 (not shown) secure the magnets in pairs on to the block and by means of an elliptical key 43 the jaws of the lamps may be opened for adjustment of the position of the electromagnets. Anti-rebound device.-A resilient stop member 66, Fig. 9, is attached to a momentum absorbing mass 63 of the same weight as the hammer 11. The mass 63 is attached by a rubber layer 64 to a bar 65. When the hammers are to be operated the stop members are raised from behind 4 shoulders 67 on the hammers 11 by a pivoting action of the bar 65 mounted on the top of a pivoted lever 71, Fig. 2 rocked by a follower and cam early in a print cycle. After the hammers are cocked the stops rest under the influence of weights 77 on the tops 76 of projections 67 on the hammers. Rebound is prevented by the stops falling behind the shoulders 67 after impression.
