The grindingwheel spindle is mounted on this turret and is 5J-2 in. indiameter, running in ball bearings both radial and endthrust, with adjustable take-ups for end wear, either forward. Rear View Showing Application of Motor and Arrangement ofGearing or backward. The spindle is driven by means of a largespur gear which meshes into a wide faced fiber pinion onthe shaft of the 25 motor mounted upon the second important feature in the machine is the partly uncovered in one of the photographs. The desiredspeed is obtained by adjusting the speed control hand lever,shown at the right in the front view of the machine, in itsproper position as indicated on the dial behind it. Thelever is locked when in position for any desired carriagetravel speed. The hand lever at the left in front of themachine is a carriage control and is locked in both workingand neutral positions. There is a corresponding lever atthe back of the machine for the convenience of the large hand wheel is for moving the carriage back andforth in adjustment to the work. The dogs on the front side of the table may be adjustedfor any length of travel up to the capacity of the machin
