Abstract

181,971. Bullen, C. June 15, 1921. Boring-bar machines; boring-bars; work-holders. -In a device for reboring engine cylinders, a locating-plug a, Fig. 4, is positioned first at a<1> at the upper end of the cylinder b in order to locate accurately a carrier c for the upper bearing d of the boring-bar e and then at a<2> to locate the lower bearing f. The plug may be adapted to cylinders of different sizes, the periphery being of tapered stepped formation as shown at a<4>. The carrier c is secured to the cylinder casting by means of studs and the lower bearing is fixed to a plate secured by fingers g and studs h. In some cases, in order to diminish the unsupported length of the boring-bar, the upper bearing d may be reversed in its carrier and packing-pieces may be employed to raise the lower bearing. A floating connection is provided between the boring- bar and the drill spindle m by means of a coupling member n and pin p. The cutters q of the boring-head are held in grooves in a member s by a ring t and are adjusted radially by a coned member r.
