Abstract

12,794. Urban, J. F. K. May 26. Screw propellers; paddle-wheels ; rudders.-The blades of rudders and screw propellers and the floats of paddle-wheels are slotted in a special manner. Figs. 1 and 2 sho the application to the blade of a screw propeller. Slots radial to the centre of the boss have waved or undulated leading and following edges which are bevelled or sharpened. Figs. 3 and 4 show the application to a paddle-wheel and a rudder respectively.
