HYDRAULIC-Assistance TESTING-MACHINE. Maximum Capacity, 500,000 lbs. Ratio from major weighing-platen to point of indicator needle in scale-case,300,000: I. Used for calibrating the hydraulic supports of all new testing ma-chines, and adjusting the poise weights with wonderful precision. Extremely sensi-tive, 200 grains on major platform will place in motion 20,000 lbs. of levers andplatforms, and deflect scale needle. No reduction of sensitiveness when fullyloaded. 312 Wm. Sellers & Co., Incorporated, Philadelphia, Pa. putting them on or taking them oflf, without having handling, is peculiar to the Emery-method. Suspended from this lever, E, at suitable intervals by thin fulcrumplates, are poise frames, N, consisting of an upper cross-head, ^, and a lowercross-head, T, united by three vertical bars disposed at equal intervals about thecross-heads.

A weight-frame, M, for carrying the weights when not in use, ofsimilar building, has its 3 vertical bracketed bars alternating with the barsof the poise-frame this weight-frame is guided, and is raised and lowered in avertical line with out touching the poise-frame, b} a rock shaft and a hand-levercoupled to the rod projecting from the cross-head R.
