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 . d to have introduced water-closets into Eng-land in Elizabeths reign, and some writers have erroneously ascribedtheir invention to him. They are described in the great French work onArlo and Manufactures, by M. Roubo, who says, thev were long used in 71 562 TIIIi>s fill Diains, ifc. [Book V^. France before being kno\\-ii in Engljuid. Those wliich ne has figured arahowever i)n the ancient phm, without traps, and such are still to be foundin oriental cities. They are not to be compared with the modern ones.(See LArt dii Metiuisier, folio edit. 1770, PI. 69 ; Gells ; ADissertation on Phices of Retirement, Lond. 1751 ; Fryers Travels inIndia and Persia, Lond. 1698.) Devices for preventing the ascent of offensive vapors from siiiks, sewers,drains, &c. are named traps. As these are simple in construction, anda[)plicable under all circumstances, and yet are little known, we haveinserted a sketch of a few of the most common. They are all modifica-tions of the same No. 279, No. 280. A A represent a floor or covering of a sink or sewer, and tlie object iato dischare refuse water or slops of any kind into the latter wilhr utallowino- currents of air to rise through the passage. No. 278 is a leadenpipe bent at one part into tlie form of a letter S, which part constitutesthe trap. One extremity enters the sink, and to the other, which is turnedup perpendicularly, the basin of a water-closet, or a common funnel isattached. The flexures of the tube must be such, that whatever liq\iid isthrown down the , a portion will always remain in the bent partbelow so as to seal the pasfasrc romvleteli/, as shown in the cut. The basiuand trap may be placed in a room at any distance above the sink or sewer,provided both are c
