                 The same idea was also applied to the milling machine of Wanderer
               make about 1960, as shown in Fig. 1-30. Furthermore regarding the size
               variation, Kearns merchandised the heavy-duty boring machine on the
               basis of the market survey. Actually, the wide ranges of the bed length,
               table width, and column height allowed the great variety of work size
               in that of Kearns. On this extension, an innovative idea was proposed
               by William Asquith. A monolithic basic pattern was predetermined as
               shown in Fig. 1-31, and a part selected from it was used as a column in
               accordance with the design requirements [6].
                 In short, the unit construction for the conventional machine tool of
               manual operation type was in salience in the 1960s as shown, further-
               more, in other examples in Table 1-3.
