Part II 2569. A potato-weighing machine {Jig. 279.), of a very complete description, has been invented by Mr. John Smith, of Edinburgh, and is figured in the Highland Society's Transactions, vol. vii. pi. iii. It is on the principle of the steelyard, and chiefly intended for weighing grain, flour, potatoes, or any other commodity usually put into a bag for carriage or keep. The machine is portable, of easy use, and not liable to go out of order. 2570. Ruthven's farmer's steelyard (Jig' 280.) is well adapted for weighing and readily discharging bulky commodities. It consists of a longer and shorter beam, with a moveable weight, to be shifted along the former, and a scale suspended to the latter. The longer arm, from its extremity, being confined within a limited range, obviates the inconvenience of jerks and long vibra- tions, while an index upon it points out the required weight, by a counterpoise being slid backwards and forwards, till the point has been found when it acts as an equiva- lent. By turning a keeper fixed to the scale, one end of it is opened, turning on a cylindrical hinge at the top, and the con- tents speedily discharged. These balances may be made of any size required, either to suit the purposes of the farm, or the household. Their simplicity secures them equally against expense of manufacture, and the risk of going wrong when in use. One weight only is required, the value of which, as
