The top drawing shows a mechanism for fast insertion of a typewriter ribbon in an electric typewriter without the necessity of handling inked portions of the typewriter ribbon. The ribbon is grasped by leader 1 and manually positioned across an extending member 3 on a driven roll. Member 3 automatically pulls the ribbon between the two feed rolls.

The bottom drawing shows a side view of rolls 5 and 7, and member 3 carried by roll 5 in direct contact with the side of roll 5.

As shown in the top drawing, casing 9 defines a housing for rolls 5 and 7 and also presents a top surface with an opening above rolls 5 and 7 for receiving the typewriter ribbon. Rigidly anchored to casing 9 and spaced above and generally parallel to the top surface of casing 9 is guide wall 11.

In operation during ribbon insert, rolls 5 and 7 are normally driven by the motor of the typewriter. The machine operator grasps leader 1 of the typewriter ribbon. The operator manually places leader 1 or the ribbon attached to it across the top of casing 9 under guide 11, then across the side of rolls 5 and 7 where those two rolls meet, and then back in slot 13 in a direction to hold leader 1 gently toward rolls 5 and 7, all as shown generally in solid outlines.

One of the two extending portions on member 3 catches leader 1. The resulting force pulls the leader 1 into the nip of rolls 5 and 7. The free end of leader 1 initially remains in position in slot 13. The result is that a loo...
