Abstract

135,989. Fisher, A., and Turbine Gears, Ltd. Dec. 30, 1918. Toothed wheels have the teeth formed so that each tooth near its tip has driving engagement at two points such as m, n, m<1>, n<1>, so that the " lines of action " l<1>, l<2> turn sharply back at such points as e, d towards the " line of centres " c. The teeth of the " basis rack " are formed with straight portions between points f, g, which are intersected by the pitch line p passing through the pitch point a. The tips above the points f and the flanks below the points g are arcs of circles. The wheel teeth are generated from rack teeth so formed, and wheels so constructed are meshed together.
