The Thomson Faucet.—The faucet represented in Fig. 10 has recently been devised by SirWilliam Tliomson. It is made entirely of metal. The metal valve. A, on reaching the seat,B. also of metal, is not suddenly arrested and compelled to seat itself hap-hazardly, but con-tinues to turn on its seat as the handle is turned, receiving meanwhile a gradually increasingpressure from the spring, C (non-corrosive), centrally applied by the rounded head of thestop, D. The valve is thus nibbed upon its seat at every opening and closing, and both valveand seat acciuire and maintain a perfect fit and finish. The manufacturers state that nomaterial wear is shown on the valve and seat, even after it has been opened and closed asmuch as would occur in many years service. The spiral spring has been subjected to com-pression 700,000 times withoutshowing
