Patent GB-1917-130025
From google patents abstract: "Relates to the attachment of air propellers to their bosses. A flanged boss keyed to the shaft comprises a sleeve portion having an integral flange at one end. The propeller is secured between the fixed flange and a loose flange at the other end by means of bolts passing through both flanges and the propeller hub. The bolts b<1> are inclined alternately in opposite directions so as to attach the loose flange to the fixed flange in such a way that the drive is transmitted through both flanges. In a modification, all the bolts may be inclined in one direction so that they take the drive in tension only. In another modification, both flanges may be separately splined on to the sleeve and all the bolts may be inclined in one direction so that, on tightening up, the flanges tend to turn in opposite directions and firmly grip the sleeve."
