摘要： A closed loop chain or train rotates continuously to move, along parallel paths, individual, laterally flexed, type carriers between a paper which moves continuously in the opposite direction and laterally shiftable latches. One end of a selected type carrier is momentarily arrested to deflect the type into contact with the moving paper for imprinting.

摘要： A HIGHER MECHANICAL FORCE OVER UNIFORM DISTANCE IN RESPONSE TO MECHANICAL PRESSURES OR ELECTRIC PULSES OF VARYING AMPLITUDE OVER VARYING DURATION IS PROVIDED FOR ONE OR A MULTIPLE OF DEVICES TO BE SHIFTED BY A SIMPLE, COMPACT, INEXPENSIVE HIGH GAIN POWER TRANSMISSION SYSTEM. AN ELECTRIC MOTOR DRIVEN POWER ROLL HAS ONE OR MORE FLEXIBLE BANDS ARRANGED LOOSELY ABOUT THE PERIPHERY. ONE END OF EACH BAND IS COUPLED TO AN OPERATING LEVER, PREFERABLY IN THE FORM OF A HANGER COMPACTLY ENCIRCLING THE POWER ROLL AND THE BAND ON ONE SIDE. THE HANGER IS PIVOTED ON ONE SIDE OF THE ROLL AND CONNECTED TO ONE END OF THE BAND ON THE OTHER SIDE OF THE ROLL. THE DEVICE TO BE SHIFTED IS ATTACHED TO AN EXTENSION OF THE HANGER NEAR THE PIVOT. THE BAND IS CONNECTED TO THE LEVER ON THE OTHER SIDE OF THE ROLL BEYOND WHICH EXTENDS A DISENGAGING PORTION OF THE LEVER. A PRESSURE ROLLER IS ARRANGED ON AN ARM TO PRESS THE BAND INTO ENGAGEMENT WITH THE PERIPHERAL SURFACE OF THE ROLL. AN ARMATURE IS ARRANGED FOR MOVEMENT IN RESPONSE TO MANUAL PRESSURE ON A KEY OR ELECTRIC ENERGIZATION OF A MAGNET, OR THE LIKE. THE MOVEMENT OF THE ARMATURE IS EXERTED THROUGH A MECHANICAL LATCH TO CAUSE THE ARM CARRYING THE PRESSURE ROLLER TO PRESS THE BAND INTO FRICTIONAL CONTACT WITH THE MOVING POWER ROLL. THE BAND THEN PULLS THE LEVER IN A DIRECTION FOR SHIFTING THE DEVICE AS DESIRED AND OPENING THE MECHANICAL LATCH THROUGH ACTION OF THE DISENGAGING EXTENSION OF THE LEVER. THUS UNIFORM TRAVEL OF THE DEVICE TO BE SHIFTED OBTAINS FROM APPLIED FORCE WHICH IS NOT NECESSARILY UNIFORM AS TO TIME OR AMPLITUDE OR DISTANCE TRAVELED.

摘要： A printer of the needle or hammer impact type prints by release of spring-stored energy, driving the needle or hammer against a platen or character ring. A rotating cam restores the printing member to a locked standby condition after impact, and an electromagnet attracts a moveable core to allow release of the printing member at selected times for printing. The gap between the moveable and fixed cores of the electromagnet is periodically closed mechanically and electrical energization of the electromagnet only maintains the attracted state of the fixed and moveable cores.

摘要： A plurality of self-restoring equally spaced apart print hammers selectively are driven lineally toward a printing position by continuously rotating impellers having equiangularly spaced radial impelling elements. Each impeller is effective through the agency of a rockable interponent, which is selectively elevated into the path of associated impelling elements upon latching of the armature of an electromagnet, for transmitting impeller force to a corresponding print hammer. An elastomeric bumper, disposed in the path of the print hammers, dampens printing force on dies, which are conveyed past said hammers for printing, in equally spaced relationship different from the spacing of said hammers. Each die, when at a printing station, is aligned with a print hammer but spaced therefrom a distance inversely proportional to its printing area for producing copy of uniform intensity.
