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 . nd alike,(such as plumbers solder in the middle of pipes.) A straight tube C Dis closed by a partition or disk in the middle of its length : as the waterwhich flow^s from the reservoir always remains in the end C, the object isto open a communication for it to pass into D. To accomplish this, slitsor other shaped openings are made through the pipe on both sides of thedisk, and a shorter but wider tube E, with a stuffing-box at each end isfitted to slide over C D. Thus, to allow water to pass into D, all that isrequired is to move E (by the two projecting handles) till both series Jl Chap. 9.] Slidiv CocJis— JVafer-Closefs. 561 openings are inclosed hy it ; while to stop the flow throno-li D, E musthe moved hack towards C as in the figure.
