Abstract:
A PRESSER DEVICE FOR MOVING A PAPER STRIP AND PRINTING RIBBON AT A CONTROLLED RATE OF SPEED AGAINST TYPE MEMBERS PRIOR TO STRIKING MOVEMENT OF PRINTING HAMMERS WHEREBY TO REDUCE PRINTING NOISE.
Abstract:
A plurality of type carriers having spaced type characters and stop teeth thereon are yieldably driven past a printing station and are arrested by engagement of electromagnetically controlled stop pawls with selected ones of the stop teeth. The type characters and stop teeth on certain of the type carriers are staggered relative to the type characters and stop teeth on other type carriers to reduce the mechanical ''''break-away'''' load and the electrical load.
Abstract:
The rockable printing sectors of a printing mechanism are provided with arcuate outwardly yieldable type sections having detenting notches therein. After the sectors have been differentially set relative to a printing line, a combined aligning and printing member is moved outwardly to align the sectors and to thereafter flex the same sufficiently to impact and/or squeeze the type characters against a paper tape and printing platen.
Abstract:
A pin carriage return mechanism is disclosed in which the pin carriage is returned from an advanced position to its initial home position by a flexible cord. The latter is attached at one end of the pin carriage and is anchored at its opposite end. An intermediate part of the cord is looped over a roller, which is orbited about a fixed center during each cycle of the machine to return the cord and pin carriage.
Abstract:
A device for eliminating the printing of zeros to the left of the highermost denominational significant digit of an amount comprising a flexible elongate strip movable endwise between the type members and printing hammers associated therewith. The strip includes an ink pervious section for transferring a visible print to a paper tape and a contiguous ink impervious section. The strip is spring moved endwise and a stop element is carried thereby to arrest against the type member registering the highermost significant digit, causing the ink impervious section to block transfer of a visible imprint of zero characters to the left of the highermost significant digit. In a modified form, the strip is moved to different positions by the pin carriage.
Abstract:
The printing sectors of a data printing mechanism are provided with arcuate outwardly movable type sections which are flexed by an elongate printing member to squeeze selected type characters against a paper tape and platen. The printing member is also previously moved endwise under control of sensing means which is arrested by the sector containing the highermost significant digit to thus locate an actuating part of the printing member under only those sectors which contain the highermost significant digit and all lower order digits and/or zeros.
Abstract:
THE PRINTING SECTORS OF AN ADDING OR CALCULTING MACHINE ARE PROVIDED WITH OUTWARDLY YIELDABLE TYPE CARRYING SECTIONS. AN ALIGNINING MEMBER IS MOVABLE OUTWARDLY INTO ENGAGEMENT WITH DETENTING NOTCHES IN THE SECTIONS, THE MEMBER FLEXING THE SECTIONS TO FORM A SOLID BASE AGAINST WHICH TYPE HAMMERS IMPACT.
