Title: Improvements in Counting Mechanisms
Inventor: GREENWOOD ERIC
IPC: G06M1/30
Filed: 1965-11-24
Abstract: 1,166,625. Counting-apparatus. ENGLISH ELECTRIC CO. Ltd. 21 Feb., 1967 [24 Nov., 1965], No. 49847/65. Heading G4D. The present demand, especially of electricity consumption, is registered on drums 3A-3C, the maximum demand in a period on drums 4A-4C, and the total of maximum demands over a number of periods on cumulative drums 5A-5C. A step-by-step drive 57 advances units, tens and hundreds gear-train 6A-6C, advancing present demand drums 3A-3C at the same time. At the end of a period a shaft 53 is rocked to disengage dogs 9, 10 but maintain spline drive 11, 12, following which the present demand drums 3A-3C are lowered (Fig. 2, not shown). Pins 14 on drums 3A-3C thus disengage from discs 15 associated with the maximum demand drums 4A-4C. Further movement of shaft 53 resets the present demand drums 3A-3C by the action of lugs 52 on cams 13A-13C. Restoration of the shaft 53 re-engages dogs 9, 10 but the pins 14 engage the underside of discs 15, so that springs 16 are compressed and the maximum demand drums are held in their present positions by castellations 18, 19 until the present demand catches up with the existing maximum demand. When the pins 14 of the hundreds drum, followed by the tens and units drums align with holes in the corresponding discs 15, the latter move down and free the maximum demand drums 4A-4C for movement with 3A-3C. The process repeats for a number of periods during which a lever 38 is in the position shown so that any movement of the maximum demand drums is transferred by pin 24 to transfer gears 28A-28C but the cumulative drums 5A-50 are held clear of these transfer gears. When the meter is to be read lever 38 is rocked clockwise to lift gear 26 clear of pin 24 and to lower drums 5A-50 on to transfer gears 28A- 28C. One rotation of shaft 2C causes cam 45 to push arm 46 to reset maximum demand drums 4A-4C. The shaft 2C also rotates gears 42-44 which take along the cumulative drums 5A-50 by means of springs 40 until pins 39 on the underside of the drums abut the ends of ramps 35 on the transfer gears 28A-28C, so adding the amount previously stored on the maximum demand drums.
