Abstract

1,253,014. Reverse gearing; toothed gearing. SIEMENS A.G. 21 Jan., 1970 [22 Jan., 1969], No. 3033/70. Headings F2D and F2Q. [Also in Division B6] In a teleprinter an output shaft on which is mounted a worm wheel 2 and which moves a typewriter carriage (22), Fig. 1 (not shown) by a wheel 19 driving a toothed belt 3 is rotated selectively in either direction about its axis by a common motor (21) through a selected one of two clutches 13, 18 driving individual shafts. These shafts may each have, for driving the wheel 2 a worm 1, 10 with a gap 1a, 10a so that after completing a revolution of the shaft the gap is opposite wheel 2 so as not to interfere with rotation of the wheel by the other worm. Control of the clutches 13, 18 involves solenoids 34, 37, levers 14, 16, 17 and cams 13c, 18c. This control is connected to a slide bar 4 and levers 5, 6, 9 co-operating with ratchet teeth 18 fixed to the wheel 2 to hold the latter when the clutches are disengaged. The two clutches 13, 18 may drive a common worm in opposite directions.
