Platform assembly

I'm afraid it is another nerdy blip tonight but it is difficult to find a half decent blip outdoors with the dull wet weather we have been having.  These are the main parts a platform escapement that is used on most clocks that do not have pendulums and is the ticking part of the mechanism. This one come from a small Elliott mantel clock I dismantled this afternoon. The photo shows how the parts interact in a sort of exploded diagram sort of way. The main train turns the escape wheel which is alternately locked and unlocked by the pink jewelled pallets. The forks and pin engage with the jewelled pin on the roller rotating the balance wheel backwards and forwards with the help of the hairspring, the length and thickness of which determine the timekeeping of the clock.  To give you an idea of scale, the escape wheel measures about 5mm. Lesson over.
