This is another view of the mechanism for operating the patent sails - see TL9773 : Stanton post mill - the patent sails TL9773 : Stanton post mill - the striking gear. The striking rod is seen entering stage left and carries the spider operating the shutters on the sail. The rack (out of sight) is moved by (or moves) the pinion that is connected to a weight via its shaft and a wood rimmed wheel. The weight is on the chain seen hanging from the wheel. The weight holds the shutters closed against the wind until the wind is strong enough to lift the weight and the shutters open to spill the wind. This gear is at the top rear of the buck and the striking rod passes through the windshaft.
