Abstract

16,720. Marks, G. C., [Underwood Typewriter Co.]. Aug. 17. Typewriters.-Relates to a tabulating-mechanism, comprising a rotating graduated stop co-operating with the tabular stops, means for setting the rotating stop, and means for actuating the carriage release. Figs. 1 and 2 show the application to an Underwood machine. The rotating stop 4, which may be formed with steps 5, or may be helical, is secured on a spring-tensioned spindle 1, connected by bevel gearing 17, 18, 22, 23 with a spring-tensioned spindle 27, provided with a knob or key 29 and a pointer 32 moving over a dial 31. The spindle 27. is. movable longitudinally in the hub 24 of the pinion 23, against the action of its spring 34, for the purpose of actuating the carriage release, and is locked against rotation during such shifting by means of a toothed disk 35 and a pin 36. The spindle 27, when shifted, engages an arm 7 of a sleeve 6 loose on the spindle 1. The sleeve 6 carries a thumb 8, resting on the carriage releasing lever 9, and a brake plate 11 for engagement against the carriage brake bar 12, which is made slightly wedge-shaped for increased braking effect towards the end of the travel of the carriage. The tabular stops 37, 38 are carried by a bar 14, pivoted in brackets 13 on the carriage and movable against the action of a spring 15 by the stop 4, for passage of the stops 37, 38.
