775 Richmond, John, Bow, Middlesex — Inventor andManufacturer.
Improved engine counter, applicable also to turnstilesfor bridges, &c. This machine is represented in the an-nexed cut.
Description of the counter :—The number of strokesmade by the engine can be read off at one view withoutcalculation. The leading or unit hand traverses theentire circumference of the large dial, and the hands ofthe three small dials, Nos. 2, 3, and 4, all revolve in thesame direction. The first motion is given by a slidingbar and fixed spring, instead of a double pallet, so thatthe first wheel cannot be thrown more than one tooth byone stroke of the engine. No skip-wheels are employed,and the hands are all moved by a train of wheels andpinions, so that the motion is regular and* progressive.
It will be seen that the arrangement is. very simple.
No. 1, or the large circle dial, contains 100 divisions,and the large hand traverses one division at each beat orstroke. No. 2 dial also contains 100 divisions, each oneof which is equivalent to one entire revolution of No. 1hand, thus registering 10,000 strokes. No. 3 dial isdivided in the same manner, registering 100,000 strokes ;and No. 4 dial is divided into 100 parts, registering1,000,000 strokes. Thus any amount can be read offwithout error.
