Abstract

9826. Wright, I. H., and Smith, Major, & Stevens. July 6. Gear-cutting.- Relates to a linkage type of toothcurve generating mechanism, and consists in an arrangement by which wheels of small diameter may be cut. Worm-wheels are produced by milling, and gear and helical wheels by shaping. The wheel blank and master wheel are mounted co-axially. A long master worm D is carried by a slide k having a pin on the line N engaging a groove in an arm H rotatable about an axis b together with an arm I slotted to engage a pin J on the cutter slide. The lines j, n pass through the pitch axles of the blank and master wheel, the distances B, b, J, j, and N, n are all equal, and the lines J, N, b are all in the same plane. Subject to these limitations the machine may be arranged with the axes B, b in various relative positions.
