HEAVY DUTY CRANK SHAPER A l()-in. heavy duty back geared crank shaper has beendeveloped recently by the Streine Tool & :ManufacturingCompany, New iSrcmen, Ohio. The base of this .«haperis of the extended type, unusually deep and affords a solidfoundation for the machine. T-slots in the large planed Back Gears, Pulley Shaft and Spindle are all in the Same Plane being lower than the outside, thereby preventing any ex-cessive cut in the bridge of the carriage. Slight improvements have been added to the taper attach-ment, particularly in the method of guiding the travelingshoe on the taper bar. There has always been a tendency ofthe shoe to lift from the bar when under pressure, which hada slight effect on the work. This has been eliminated bythe introduction of a gib engaging a ledge planed the entirelength of the taper bar. Graduated dials, reading in thethousandths of an inch, are made a part of the rest the lathe is belt driven directly from the main line or
