Braintree and Bocking (3), Essex, England
This view is looking down through the hatch three floors up and through the hatch in floor below down to the ground floor. Somebody can be seen climbing the first set of steps from the ground floor.
The steps up to this floor can be seen together with, in the bottom left corner of the nearest hatch, part of the black roof of the lower brick part of the mill.
Looking up underneath one of a pair of millstones (the light circular object) on the floor above and the handle which engages or disengages the gear that drives the millstone is clearly visible.
The larger drive gear to the left is driven by the mill's sails.
Looking up the steps and through the hatch to the penultimate floor where some of the driving gears can be seen. The white cloth is actually a cloth tube which would have fed the grain from hoppers on the floor above to the millstones.
The treads on some of these sets of steps are very close together although I'm not able to say why.
This, on the penultimate floor, shows the main driving shaft, at the top of the picture, which is connected directly to the sails. The very large vertically mounted gear wheel at the back, which is connected to the main shaft, drives the smaller horizontally mounted gears which in turn drive the millstones.
There is one more floor above this which is really only a relatively small platform directly under the roof and is where the grain hoppers are located.
