Abstract

180,030. Willmot, A. S., and Hockly, S. Feb. 15, 1921. Boring curved cylinders.-The drill 10 is driven by a flexible shaft 6 passing through a curved sleeve 5, of smaller diameter than the drill, fixed to a framework 1 carrying the driving-gear. The work is carried by a table 3 pivoted to an arm 13 of the framework and actuated by a handle 14. Holes of different curvatures can be drilled by using sleeves of corresponding forms, the pivot 11 of the table being adjusted to suit.
