The. Speed and Feed Recording Device Aids in Increasing Production excuse that there was no ready and accurate means of de-termining cutting speeds and feeds no longer holds sincethe advent of a new device made by O. Zernickow, 15 ParkRow, New York. This device, known as the O-Z cutmeter, can be used indetermining the cutting speeds of lathes, milling machines,planers, drills, etc.; also for ascertaining the speeds ofpulleys, belts and ropes. Its operation depends upon thegovernor principle and the accuracy of the instrument is notaffected by changes in temperature, moisture or magneticfields. A damping mechanism minimizes the effect of vibra-tion of the indicating hand and also neutralizes the shocksand vibration of the machine under test. This makes read-ings easy and distinct. Instantaneous readings in ft. permin. are shown and when used with a pointer, rev. per watch is required in calculating the speeds. The instrument is well balanced and will indicate withequal accuracy in ve
