Two threaded holes are shownthrough the upper shell of the shaft-bearing box and a noteattached by a line and an arrow point to the upper view explainsthat they are to be drilled ^ inch for a |-inch tap. Finally, theupper surfaces of the oil box are marked / to be machined. PLATE XXSHAFT=BEARINQ PEDESTAL Pla£e XX shows a shaft-bearing pedestal in which the shaft-bearing box is a separate unit (not shown) which may be supportedinside the pedestal. As the shaft-bearing box would be heldexactly central with the frame of the pedestal, many of the work-ing lines of the left side view are drawn around the center line, oraxis, and several of the dimensions are figured as a radius from acommon center. The views consist of a front, or edge, view, aleft side view, and two smaller views, one of which is a section online A-B and the other is placed just below the side view a
