The feedingmotions for the saddles and cutter-bars are obtained by meansof friction disks, which admit of an infinite gradation from 0to 1 in. in width per revolution of table. The amount of feedfor each bar can be varied, stopped, or started without anyreference whatever to that of the other bar. This machine enables the Robert Poole & Son Company todo a class of heavy work which few or no other establishmentsin the country are prepared to undertake. It is also an excel-lent example of the heavy machine tools the enterprising Phila-delphia firm is DELANEYS COIL AND RING PACKING ANDGASKETS. The accompanying engravings represent the sectional ringaiHl coil packing for piston and pump-rods, valve-stems, etc. These arc made by a process which, it is claimed, affordsperfect luln-icalion, and it exjiands in such a way as to relievethe rods from all undue pressure. It is said to be extremelydurable, and owing to the materials used and the method ofmanufacture, it is never burned or hardened while in use. The lower engraving represents the manhole gaskets of thesame makers. are said to form especially durable steamand water-tight joints, being made to stand a pressure of 300lbs. These goods are manufactured by Messrs. li. J. De-laney & Company, Milwaukee, Wis. STARRETTS NEW TOOLS. The accompanying engravings illustrate some new tools L. S. Starrett, of Athol, Mass.
