. Railway mechanical engineer . llic feed box, by whicli speeds and feeds may be changed whilethe machine is in molinu. All lexers and handles for the con-trol of the machine are localed in finnl uitbin easy reach of theoperator. The machines are ec|uip|ied with anlnmatic cross feed whichcan be set for the reduction of any amount from . in. in. at eitbtr or bntb cuds of tile talile reverse. Feeding au-tomatically on one end only is especially advantageous whengrinding against a square shoulder. The feed is automaticallythrown out when work is ground to size, and a positive stop isprovided when feeding the wheel by hand in the production ofduplicate work, .^n auxiliary feed for bringing the wheel auto-matically into the work when the table is not being traversedcan lie supplied. This is desirable when the work is short andcan be covered liy the full width of the wheel. The cross feedhand wheel is graduated to .0005 in. in plain \icw of the opera-tor. The automatic cross feed is adjusted by the movement of. Self-Contalned Single Pulley Universal Grinder a lever to the point desired, as indicated on a graduated dialplate, and may be instantly changed to any feed while the ma-chine is in operation. The table is provided with power traverse, wliich is controlledby means of a lever placed to the left of the table hand when power is applied to the table the hand wheel is auto-matically disengaged and remains stationary. When power isremoved from the table the hand wheel is simultaneously en-gaged for traversing the table by hand. Another feature of note is a variable tarrying device, by wliich llie tarry at each end ofihe stroke can be regulated. The base of the machine is of massive proportions and iscrossbraced to insure rigidity. Klat and V guides are used asthe sliding table, the swivel table and under the wheel base rests upon three points, preventing cross strain and in-suring perfect alinement of the machine.
