Patent GB-214297-A (GB)
Abstract: 214,297. Phinney, E. E. Nov. 18, 1921. Multiplying and dividing apparatus.-In calculating-machines in which reversible numeral wheels are actuated by differential actuating mechanism which is always rotated or effectively moved in the same direction bv means such as a handle, means are provided which is automatically operated on reversal of the handle to effect reverse rotation of the numeral wheels. Wheels 10 are positioned along shafts 11 corresponding to the various denominations by thumb-pieces 12 sliding in slots 13. When the main handle 4 is turned a shaft 7 is rotated and through bevel gears 8, moves a series of shafts 3, carrying wheels 2 each having nine teeth of different lengths, rocking the shafts 11 differentially. The drive is transmitted from the shafts 11 to the totalizer wheels through one of a pair of bevel wheels 16, 17 on each shaft according as to whether addition or subtraction is intended. The clutches moving these wheels are shifted by a slide 31. This in turn is moved by a bell-crank lever 46 pivoted at 33. Normally this is held in position by a leaf spring 58 which engages the side of the nose 60 snapping it home during the last part of the movement. The lever 46 is connected by pin-and-slot to a link 44 attached to) a bell-crank lever 42 connected in turn by a pin-and-slot to an arm 40 on a friction-disc 39 pressed by springs 37 against a toothed wheel 35 fast with the handle. The wheel 35 is provided with a gap 47. On moving the handle, the end of the lever 42 is first carried down into the gap and is then moved positively. If an attempt is made to reverse the movement after it has once started, the movement is prevented by the end of the lever 42 engaging the teeth of the wheel 35. The shaft 7 is driven from the handle through a bevel gear 6 which engages two bevel wheels loose on the shaft 7 but provided with spring pins engaging teeth on a part fixed to the shaft.
