Abstract

14,453. Thomas, F. June 15. Drilling - machines.- In a portable drilling- machine with a combined driving-mechanism and differential feed, the driving - mechanism comprises a chain-driven wheel f, which drives through another chain f<1> a wheel i on the drill spindle and also a wheel n<1> attached to a gearwheel n, which in turn is geared to a feed-nut l, which is thereby rotated, but at a different speed to the drill spindle. This nut is provided with a back centre l<2>, so that the drill can be positioned. Specifications 753/79, [Class 85, Mining &c.], 617/81, and 3492/98 are referred to.
