Occasionally, however, a design ofsuch novelty is brought out that it warrants an entry intothe patent office and a place upon the market. Such adevice is this universal chuck that is here illustrated. Itwas designed in the 17th street shops of the Chesapeake& Ohio Ry. at Richmond. Virginia, and is now beingmanufactured by the Commonwealth Supply Co. of thesame place. It is intended primarily for use on boring machines for bottom surfaces and at the ends. It is also fitted witha dovetail groove from end to end to take the maincarriages 2. These are also of cast iron and are madewith a dovetail to fit into the groove of the base. Thesedownward projections of the dovetails are cut with aright and left hand thread respectively to take the cor-responding threads of-the screw. The mai
