to the second lamination by an infinitely adjustable angle
sufficient to define a desired skew angle after which the
indentations are interlocked.
The patent to Zimmerle (Figures 7, 8, 11, and 12) teaches a
dynamoelectric machine lamination assembly and procedure
including three special holes 75, 85 that permit angular
displacement between adjacent laminations so as to allow
sufficient space for interlock means 76 to be skewed
simultaneously with skewing the winding slots along the outer
periphery of each of the rotor laminations (column 5, lines 61
through 71 and column 7, lines 28 through 33). We understand that
this discrete arrangement of special holes would permit limited
relative angular displacement between laminations based upon the
circumferential extent of the holes.
The Martin patent relates to a laminated assembly for a
dynamoelectric machine that includes interlocking projections and
recesses for securing adjacent laminations together by
compressive interference fit, wherein the compressive
interference fit is between ridges 52 on the projection 54 and
the recess 40 (Figures 3A and 4). It is clear to us that the
Martin teaching is concerned with a plurality of interlocking
projections and recesses on each lamination for securing adjacent
