C. L. Rice & Co., 243-5 Lake Street, exhibited some excellent tools by Edwin Harrington & Son, of Philadelphia. One was a 22" lathe which by extension of the bed, can be made, if necessary, to take in 36" work, a carefully designed and well-proportioned tool. Another of their exhibits was the 36" drill which we illustrate herewith by the same makers as the lathe, and of simple form and compact appearance. The steel spindle is 2" dia.; 12" traverse; quick return; geared for 3 changes of self or hand-feed; driven by four speed cone 15" dia. for 3" belt; back gearing giving speeds to spindle; the table revolves on the columns and is raised or lowered by gearing and screw running through a wrought-iron nut, or held in a central position by a pin passing through a bracket into the wrought-iron slide. The general dimensions are, distance from base to spindle 54 ins.; from centre of table to column, 18 ins., and weight of whole machine is 3300 lbs. |
