Abstract

The top drawing shows bedplates 1A, 1B, and plate 3 with probe 5 operative to aid in efficient and convenient insertion of a typewriter ribbon in the ribbon feed mechanisms of an electric typewriter. Leader 7 of a typewriter. ribbon is manually placed on bedplates 1A and 1B. Plate 3 is moved down to cause probe 5 to push leader 7 into the feeding mechanisms.

Ribbon Insert Aid

The top drawing shows bedplates 1A, 1B, and plate 3 with probe 5 operative to aid in efficient and convenient insertion of a typewriter ribbon in the ribbon feed mechanisms of an electric typewriter. Leader 7 of a typewriter. ribbon is manually placed on bedplates 1A and 1B. Plate 3 is moved down to cause probe 5 to push leader 7 into the feeding mechanisms.

Feed roll 9 is rotated from a motor which is a part of the electric typewriter. Roll 11 is an idler roll driven by roll 9 and mounted for slight movement away from roll 9, but normally biased into contact with roll 9.

Plates 1A and 1B are generally horizontally disposed to form the top of a housing which covers rolls 9 and 11. Plates 1A and 1B are spaced apart above rolls 9 and 11 an amount sufficient to permit probe 5 to push leader 7 between rolls 9 and 11. Plate 3 is hinged at 13 to one side of beds 1A and 1B. Plate 3 is connected to be controlled for pivoting on hinges 13 by rigid link 15. The latter is directly connected to lever 17. The bottom drawing shows plate 3 linked to lever
17.

To use the device, the machine operator moves plate 3 up by manually moving lever 17 down to the stop position. This raises probe 5 an amount sufficient to permit leader 7 to be placed across both plates 1A and 1B. Leader 7 is so positioned manually by the operator. Then the operator closes plate 3 by moving lever 17 up to the feed position. That causes leader 7 to be intersected by probe 5 and pushed bet...
