A descriptive and historical account of hydraulic and other machines for raising water, ancient and modern : with observations on various subjects connected with the mechanic arts: including the progressive development of the steam engine . her Asiatic macliincs moved in a similar manner^lis AiiuquUy. Combination ollevers and gutters—Swingingor IliiJulum Macliiue—Rocking gutters—Dutch Scoop—Flash Wheel, JlotiT of the n;;ichiiiC5J hitherto noticed, raise water by means of flexi-ble cords or chains, and are generally appli^able to wells of great now enter upon the examination of another variety, which, with oneexception, (the chain of pots) are composed of inflexible mateiials, andraise water to limited heights only. Afiother important distinction be-tween them is this—In preceding machines, the mechanical powers aredistinct from the hydraulic apparatus, i. e. the wheels, pulleys, windlas?--,capstan, &c. form no essential part of the machine proper fur raising thevatcr, but are merely employed to transmit motion to them; whereasthose we are now about to describe, are made in the fonn of levers,wheels, &lg. and are propelled as such. The ft)llowing figure, representsf-ne of the earliest No. 30. Single Gutter. It IS smiply a trough or gutter, the open end of which rests on thebank, over which the is to be elevated; the other end beingclosed is plunged into the liquid, and then raised till its contents are dis-charced. It ibrms what is called a lever of the second order, the loadbeing between the fulcrum and the power.
