Abstract

1,072,598. Counters. REYMOND & CO. S.A. Sept. 10, 1965 [Sept. 23, 1964], No. 38825/65. Heading G4D. A manually operated counting device which provides an indication of when a gramophone pick-up needle needs replacement comprises a spring return lever 5 which when a record is played by the needle is manually actuated one or more times dependent on the size of the record, a ratchet wheel 9 co-operating with a pawl 5a at the end of the lever, a wheel 7 in gear with a pinion 8 which is integral with the ratchet wheel and a coloured snail-cam shaped marker on the wheel 7. The marker cooperates with a window 3 in a cover (not shown) and the arrangement is such that the marker, commencing at the left side of the window, moves across and completely fills the window during the working life of the needle.
