Patent GB-902518-A (GB)
Abstract: 902,518. Typewriters. NATIONAL CASH REGISTER CO. Jan. 26, 1961 [Feb. 16, 1960], No. 3039/61. Class 100 (4). [Also in Groups XIX and XXIV] A device for setting the wheels of a counter or an indicating device comprising a selector member rotatably mounted within a sleeve and selectively adjustable to connect or disconnect any one of a number of driving members with its associated wheel according to whether the selector member is rotated in one or the other direction. Numeral wheels 17-25 mounted on sleeve 11 are restrained in movement by a comb-spring 50. A circular comb-spring 29 inside the sleeve 11 has its base engaged in a slot 30. A shaft 31 inside the sleeve has a cam such as 41 corresponding to each numeral wheel such that when a knob 46 is turned counter-clockwise to indicate a particular denomination on flange 13 then the corresponding cam engages the end 42 of a comb-tooth to make it project through slot 12 in the sleeve. If the knob 46 is now turned in a clockwise direction the selected wheel is driven through ratchet 45 and pawl 43, flange 13 and sleeve 11 until the desired digit appears in window 53. A turnedover end of pawl 43 prevents this movement unless the wheels are properly aligned with gaps 55.
