Abstract
510,444. Calculating apparatus; games scoring-apparatus. DUNCAN, A. W., and GREENWAY, W. Feb. 1, 1938, No. 3066. [Class 106 (i)] [Also in Group XV] Counting-apparatus, particularly for games such as darts, comprises. a number of dials 28 mounted on parallel spindles 26 each of which carries a ten-toothed wheel 29, 30, restricted to rotate in one direction only (e.g. by means of a pawl and ratchet), transfer from a lower to a higher wheel being effected by a spring- loaded finger 31 which is shaped for displacement against its spring so as to allow the higher wheel to be turned independently without affecting the lower wheel. The finger 31 has a cam surface 32 whereby it is forced out of the path of the wheel 29 when the latter is rotated directly by the knob 23. Idle wheels may be interposed between each pair of wheels 29, 30, so that all the dials will rotate in the same direction. An auxiliary dial 45 may be associated with each main dial 36 to indicate the last score made. Gear wheels 38, 43, driving this auxiliary dial may be disengaged by depressing a button 49 against the action of a spring 46 which also serves to return the dial 45 to zero. A similar disengagement takes place when the main knob 42 is rotated through more than a complete turn, a stop, 47 engaging a cam-shaped fixed stop 48 to force the gear wheel 43 downwards. A one-way coupling 40 prevents any transfer movement given to the toothed wheel A from being transmitted to the auxiliary dial.
