It looks like that method was known by 1880, if I read https://archive.org/details/indispensablebic00stur/page/14/m... correctly ('The "indispensable" bicyclist's handbook; a complete cyclopaedia on the subject') correctly:

> The Centaur Crank is first screwed up to a shoulder on the axle with right and left-handed threads, so that the pressure of the foot tends to make it all the more secure ; whilst, to prevent its loosening by “ back-pedalling,” a slightly tapered conical pin is driven through both crank and axle, and secured with a nut.
