AMERICAN ENGINEER AND RAILROAD JOURNAL. 405 15-INCH SINGLE GEARED CRANK SHAPER. The American Tool Works Company, of Cincinnati, has re-cently brought out a new 15 in. single geared crank shaper whichembodies a number of important improvements. Some idea ofthe capacity of this machine may be gained from the followingdata from tests made at the works.

The stroke of the ram is positive. AMERICAN SINGLE GEARED CRANK SHAPER. and has four rates of speed ranging from 20 to 65 strokes perminute. The length of the stroke may easily be changed with-out stopping the machine. The device for positioning the strokeis located on the ram near the head and may be manipulatedwhile the machine is in operation. The pointer on the ram andan index indicate the length of the stroke. The rocker arm, ofrigid and heavy construction, is so arranged as to give the rama practically uniform rate of speed during the entire stroke; italso provides for an exceedingly quick return. The drivingmechanism is sufficiently powerful for the heaviest work adaptedto this type of machine. The cross feed is of a new patented design, is variable andautomatic, and has a range of from .008 to .200 in., any one ofthe feeds being instantly obtainable while the machine is in op-eration. It is supplied with a pointer and graduations eitherside of zero reading from I to 25
