Universal Lathe Chuck. By Michael Neckerman, of Pittsburg,Pa.—The design of the inventor of this improvement is to permit thecentreing of an object in lathe either on its centre or eccentrically, asmay be desired, without inconvenience. Most chucks are so arrangedthat the article cannot be centred eccentrically without takuig thechuck apart to alter the position of the jaws; after use thechuck must again be taken to pieces to restore the parts. In the pre s-ent invention there is an ingenious arrangement, whereby the chuckmay be instantly altered to hold the object eccentrically or otherwise,at pleasure. 178 American Patents.
