"Vintage Machinery" entry for Webster & Bennett
Description:
Abstract:

One spindle C<2> of a duplex boring and turning mill is driven through reversing-gearing F, so that when turning, the tables may run as usual in opposite directions, but when boring, they may run in the same direction, thus avoiding the provision of special reamers &c. The feed is driven from the non- reversing shaft of the gearing.
