Abstract

3304. G³ttner, M. Feb. 11. Driving. - Relates to variable-speed gearing applicable to centrifugal machines &c. The driving and driven wheels d, f are geared together by a hemispherical roller e, the spindle of which is pivoted on an axis h passing through the centre of the sphere at right-angles to the axis of the wheels d, f. The roller is pressed outwards on its spindle into contact with the wheels f, d by means of a spring. Fig. 4 shows a modification, in which centrifugal weights are employed to increase the effect of the spring n as the speed increases.
