Theinner or boring s])indlo. reamed for a Morse socket,has a power-feed 13 in. in both directions, and its thrust, directly from the back, is operatedby a screw attached to it by an interlocking device. Feed is taken from a worm on the mainspindle and is geared to a feed-shaft for hand or power feed. This feed-shaft, on its frontend, has a hand-wheel, giving a quick return. From there it extends to tiie end of the mainspindles, where it is geared to the feed-screw by a sensitive friction-gear, so that the power-feed can be set, in case a drill be dull or feed too fast, to regulate the thrust automaticajly. as a workman would by hand. The overhead arm sup-ports a detachable drill-jig peiulant. The platenhas an adjustment graduated t
