  • Linespacing apparatus
    Patent number: 4365904
    Abstract: A linespacing apparatus includes a slip clutch assembly which is driven by an electric motor. The slip clutch assembly includes a face cam which drives a linkage which, in turn, indexes a platen in order to linespace the platen. The face cam includes an abutment portion which abruptly halts the motion of the linkage and the slip clutch assembly prevents bounce or recoil of the linkage thereby promoting smooth operation of the apparatus. The linkage may be adjusted by an operator to vary the amount of rotation of the platen during each operating stroke of the linkage.
