Haukila Estate, Tyrväntö
This mill is complete except for the sails which were cloth-spread, with narrow leading boards, and turned anti-clockwise. The braced tail pole, shingled tower and gambrel cap are in the Häme tradition. Inside, however, the mill equipment was of the greatest interest. The wooden windshaft, of two longitudinal timbers with a stone neck-bearing, had broken behind the neck, but the pine clasp-arm brake-wheel is at the tail. It has filters inside the cants, a feature not seen elsewhere. The arms are of straight birch, and so is the brake which has a Spanish windlass mounted behind, below and to one side of the neck. The brakewheel cogs are of knotty birch and held with large flat birch wedges and the lantern wallower has birch staves. The octagonal pine upright shaft carries a clasp-arm great spur wheel on the ground floor, which has a down-turned face gear below it. The two lantern stone nuts are on wood-cased quants driving 4 ft. diameter granite stones with octagonal casings on a high furst on the ground floor. The hoppers are let into the first floor itself and the meal spouts each have four sack hooks. Gates for the shoes are controlled by wooden ratchets and pawls on the sides of the hoppers. The bridgetrees are of wood with normal bridging boxes and the stones are hand tentered with wooden levers set and pegged in place. The stone-nuts are winched in and out of gear with a rope and winch operating on a frame which bridges the sprattle of the upright shaft. There is also a portable wooden winch on the first floor for raising the stones.
The down-turned face gear on the upright shaft drives a lantern pinion on a layshaft with a pulley driving down to a shingle machine outside the mill. The machine shaft has a pivoted bearer to engage the gear and there are four shingled gauges for setting the position of the shingles according to the overlap required. There is a pair of peeling stones in a square casing with a large hopper and a small shoe, and a lantern pinion wedged in and out of gear; a fan for the groat husks is fixed in the ceiling between the grinding stones and a vertical peeling machine. On the second floor is a toll chest with three divisions for oats, barley and rye respectively; the toll was taken either in meal or its money equivalent. The hand sack-hoist has a wooden Y-wheel.
