Abstract

1432984 Selective printing TELETYPE CORP 29 June 1973 [3 July 1972] 31061/73 Heading B6F For use in an "on the fly" printer a hammer driving mechanism includes an impeller 84, an interposer 92 movable by an electromagnet 125, when energized, to provide momentum transfer from the impeller to slidable hammer 86, the mechanism being such that after the momentum transfer has been completed the interposer is out of the control of the electromagnet 122. For each hammer 86 there is an interposer 92 controlled by armature 124 of electromagnet 126. When it is energized one end of the interposer 92 is moved into the path of rotating teeth 83. One of the teeth engages it and causes it to drive the hammer 86 forward. In so doing the interposer 92 is rocked so that its end 99 is moved out of contact with surface 138 of armature 124. This ensures that if the electromagnet is still energized the hammer cannot be hit twice accidentally. On de-energizing the Fig. 2 position is resumed. Springs 110, 166, 170 bias the hammer armature and interposer to their respective Fig. 2 positions.
