Thisconstruction also permits the pistons to turn in the cylinders sotliat wear is evenly distributed. The crank shaft works on ball bearings of the separator type,which, it is claimed, is superior to the full type of bearing formachines of this character operating at medium and high speeds,as in the full type of construction the balls come in contact and AIR VENTILATED JOURNAL BOX. Part Sectional View of the Little David Drill wear flat rings on their circumferences in a short time, result-ing in loose bearings and generally unsatisfactory rapid wear is largely due to the fact that the balls are ro-tating in opposite directions at their points of contact. The spindle is provided with a ball thrust bearing interposedbetween the shell and feed spindle in such a manner that themain frame is relieved of all strain. Each valve controls two pistons which act on alternate strokes.
