Abstract
405,783. Securing mirror - wheels on shafts. PAPST, H., St. Georgen, Scharzwald, Germany. Dec. 23, 1932, No. 36539. Convention date, Dec. 23, 1931. [Class 80 (ii).] A television mirror-wheel 1 is adjustably secured to a shaft 4 by the provision on the shaft of an accuratelyturned fitting-surface 7 having a flange 5 through which are screwed three fine set-screws 8 which bear on the mirror-wheel at points opposite the free ends of three radial bladesprings 6, centrally secured to the other side of the disc. By turning only two of the screws the plane of the mirror-wheel can be adjusted.
