the examiner's position. The Delta instruction manual teaches
a table saw of the type having a splitter mounted directly
behind the saw blade and a guard that is supported on the
splitter by pivoted links in such a manner that the guard is
movable toward and away from the surface of the saw table.
Thus, Delta instruction manual teaches a table saw which (1)
has a movably mounted guard that is supported on a splitter
and which is of rather simple construction and (2) does not
have a safety device which a includes detector and interlock
system. Hewitt, while teaching a table saw which has a
movable guard and safety device that includes both a detector
and interlock system, does so in the context of a relatively
complicated mechanism for mounting the guard and the actuator
for the safety device. That is, in Hewitt, rather than being
supported on a splitter by pivoted links (Hewitt has no
splitter whatsoever), the guard is suspended from a
telescoping arm 16 that extends over the top of the table saw
by a bracket 46, and this bracket is in turn attached to a
pivotally mounted "superstructure" 28 in order that the guard
may be pivoted from an active position over the saw blade and
work supporting surface of the table saw to an inactive
