Illustration of the Frictionless spiral shaft and patent attachment with “Empire” ball bearing knife attached, as fitted to Brown’s “Empire” Power Clippers. Can be driven with perfect ease even when shaft is knotted (as illustrated), or turned at a most acute angle. The invention of this spiral shaft disposes of the old and crude method of driving with a chain shaft, the links of which are liable to break or kink, and which compels the use of the clumsy device known as a “wrist joint.”
