Modern mechanism, exhibiting the latest progress in machines, motors, and the transmission of power, being a supplementary volume to Appletons' cyclopaedia of applied mechanics . haft, smallerdriving pulleys as a consequence, and the ability to use aslarge a proportion of the very variable quantity of waterto the best advantage, or as near full gate as possible. 7he Collins Wheel.—A form of gate, similar in effectto that used on the Fontaine turbine, exhibited by , Meurice & Co., in London, in 1851, and whichmay be called a plunger gate, is used on the Collins downward flow turbine shown in Fig. 3. This form ofgate raised the efficiency of the Collins wheel to 85 per cent,at full gate, and 66 per cent, with water, which Pro-fessor Thurston says is the best performance of a Jonvalturbine on record. Another well-known form of the Jonval turbine is the Geyelin, built by Messrs. R. D. Wood & of Philadel-phia. One of these wheels, as tested by the writer, at the Fig. Collms Exposition in 1870, gave over 84 per cent, neteffect, and practically the same result was obtained from a 7-ft. wheel of the same style.
