A forward or backwardturn is completed at the same point, the natural position,and. although a wide leeway is allowed, the mechanism isabsolutely locked attaint error or change during the turnof the crank. When the work is done and the answernoted, no time is wasted in the clear-out. Simply a reverseturn of tin small clear-out crank raises the carriage andclears tin . i in I« simultaneously. A forward turn clears theupper dials. Other features make for speed and ac-curacy. November 26, 1921 MINING AND SCIENTIFIC PR V. ot T. A.
