Abstract
An adapter tip assembly wherein the nose of the adapter which is received in a tip socket has a circular rear base joined to an ellipsoidal portion which tapers to an elliptical front end such that the external front surface of the tip has a wider horizontal dimension than vertical dimension and the tip is retained on the nose by a retaining pin; the front end ellipse is diminished by upper and lower rearwardly extending flat surfaces and these surfaces merge into upwardly and rearwardly angled surfaces which in turn merge into the ellipsoidal portion.
