A Vickers Range Clock's mechanism revealed.[1]
The Vickers Range Clock was a simple clockwork range clock, Admiralty Pattern Number 3778[1] built by Vickers to a conceptual design suggested by Percy Scott. It was built in large numbers starting in 1906.[2]
By 1920, there were several models:[3]
- Pattern 105 with a single-friction disc and rate drum with spiral scale
- Pattern 710 similar, with a double-friction disc and rate drum
- Pattern 816 with double-friction works and cyclometer range counter
- Pattern 3778 with double friction works and rate dial
- Vickers' Transmitting Clock
- Vickers' Transmitting Clock Mark F
- Elliott's Range Keeping Instruments Marks I and II (obsolescent in 1920)
- Elliott's Range Keeping Instruments Marks III and IV
