Abstract
726,383. Yielding bearing supports. FILHOL, Ltd., J. P. July 14, 1953, No. 19460/53. Class 12 (1) A spring-mounted jewel assembly comprises a tube 11 having captive therein an axially-slidable jewel bearing 14 spaced from a plug 20 by a helical spring 15 which is guided by a stem 21 of the plug 20. The jewel may be synthetic sapphire. The stem 21 also limits the axial displacement of the bearing 14. In a modification the end of the spring is located in a blind bore 26, Fig. 3, in a plug 25.
