Abstract

20,413. Richardson, W. J., and Etheridge, H. Sept. 9. Platen-roller couplings.-The line-spacing wheel C is provided with a conical face C' normally held in engagement with the conical face B<2> of a friction member B on the platen spindle by levers F actuated by a plunger E. The plunger is provided with a cross-pin E<3> received by a slot D<3> in the face of a boss D<2> on the cover plate D of the friction member B. The wheel C is freed by pressiug-in the plunger E, which tilts the leve-s F about the fulcrum points F<1>. The plunger may be retained in the inner position by engaging the cross-pin E<3> behind the inner face of the bo@s D<2>.
