I am trying to find a definition of this curve, which is described in old lathe design manuals - not finding anything on the internet - any of you guys have a good reference?

"Tractrix. The curve known as a tractrix, frequently also called the "Schiele" curve or the "anti-friction" curve, has been supposed to give the correct outline for an end-thrust bearing, because the wear in the direction of the axis of the thrust shaft will be uniform at all points when the pivot is given the form determined by this curve. It has been shown, however, that the merits of a pivot bearing shaped in this manner have been greatly over-estimated; and the term "anti-friction," applied to the curve, is a misnomer, since the friction of the bearing designed in accordance with it is greater than that of a flat step or collar of the same diameter."

There's plenty on the net as regards "tractrix"
