(Cl. 'T7-73.5)
The present invention relates generally to
countersink devices. More particularly the in
vention relates to that type of countersink device
which is adapted to be driven by an electric or
pneumatic motor, operates to countersink the
outer ends of previously drilled holes, such, for
example, as those that are formed in aircraft for
the reception of rivets of the flush or fiat head
variety, and as its principal component parts
comprises: (1) a composite tubulal` body in the
form of inner and outer ring shaped shells; (2)
a rotary countersink- ‘tool which is positioned
adjacent one end of, and in axial alignment with,
the body and has cutting edges for countersink
adaptorv and the countersink tool is positioned
immediately adjacent the cutting edges of the
tool with the result that the device as a whole is
extremely stable in connection with use thereof.
Another object of the invention is to provide a
countersink device of the heretofore mentioned
type in which the countersink tool is rotatably
mounted in the tubular body in a simple and
novel manner and the body has a twofold pur-í '
pose in that it serves not only slidably to support
the combined guide and stop member but also
so to limit tilting of the adaptor relatively to`
the countersink tool as to prevent the adaptor
from being laterally displaced to such an- extent _
forming purposes; (3) a rotary adaptor which is 16 as to cause the universal joint between the
adaptor and the tool to bind.
Another object of the invention is to provide
