Abstract

160,602. Pearn, W. A. Jan. 8, 1920. Boring; boring-bars. -A boring-bar adapted for producing taper or spherical surfaces is pivotally mounted at one end in a holder b adjustable on a rotating face-plate f and has a spherical collar c working in a correspondingly-shaped part in a steady e. The tool f is secured in a ring- shaped holder g having a nut engaged by a screwed spindle h carrying a spur - wheel j driven from a spurwheel m on the boring- bar through the spur-wheel k. The latter is mounted in a frame z on an eccentric pin, which may be rotated to disengage the wheel k and allow the tool to be set by rotating the spindle h by hand. The frame z is prevented from rotating by a weight 2, and the gearing is so arranged that the rotation of the boring-bar produces a slow traverse of the tool. Spherical surfaces may be produced by the arrangement shown in Fig. 5, the movable member b being connected by a link v to a tool-holder t pivoted at u.
