DIRECT MOTOR-DRIVEN PROFILER. The accompanying engraving illustrates a profiling machinedriven directly by means of a Bullock motor. This machineis rather a difficult one in which to directly apply an electricmotor, as the length of shaft between the motor and spindle isof necessity a vaiying length, caused by the continuous move-ment of the carrier. To avoid the use of intermediate l) Direct Motor Driven Profiler. which is generally necessary on machines having a verticalmovement of the spindle, the Bullock Electric ManufacturingCompany have placed the motor upon a base which is pivotedto the frame of the machine. This allows a vertical move-ment of the spindle and at the same time the shaft is kept atright angles with it by means of a joint in the spindle. Asplined shaft and sleeve connects between motor and spindle,which adjusts itself to the variations in length by the slidingof the shaft within the sleeve. The motor is fully described in Bulletin No. 2,435, whichmay be obtained by addressing the Bullock Electric Manu-facturing Company, Cincinnati, Ohio. 62 AMERICAN ENGINEER AND RAILROAD JOURNAL.
