An encyclopædia of agriculture [electronic An encyclopædia of agriculture [electronic resource] : comprising the theory and practice of the valuation, transfer, laying out, improvement, and management of landed property, and the cultivation and economy of the animal and vegetable productions of agriculture, including all the latest improvements, a general history of agriculture in all countries, and a statistical view of its present state, with suggestions for its future progress in the British Isles encyclopdiaofa01loud Year: 1831 1278 SUPPLEMENT. As it is absolutely necessary to have a steady and uniform motion to produce the best possible sample from a winnowing machine, and as the velocity of the threshing machine is subject to vary, from irregular feeding and other causes, the winnowing or dressing machines are set in motion by a small water-wheel x, five feet diameter, on the axis of 1139 which is a bevel wheel twenty inches in diameter, working into a pinion on an inclined shaft y. On the upper end of the shaft y is a bevel wheel working into a pinion, on the axis of which is another bevel wheel giving motion to the shaft %%%%%%%%%%%%%%%%, which turns the fanners by means of small mitre wheels. The bone-mill and chaff-cutting machine are driven by the mitre wheels _/' and k. On the shaft 2 is a shifting pinion 3 of sixteen cogs (ten inches diameter), working into the wheel 4 of 49 cogs (two feet four inches diameter), on the axis of which is a pinion 5 of 16 cogs (ten inches diameter), driving the wheel 6 of 49 cogs (two feet four inches diameter), in the axis of one of the lower crushers: the upper pair of crushers are driven by the wheel 6 working into a wheel 7 in the upper crush or spindle. The crushing rollers are set to or from each other as the nature of the work may require. When the bones are large, the upper pair of crushers only are used in passing the bones the first time through, an inclined board being placed to prevent them from falling i
