Abstract

597,255. Ball joints. CINEMATELEVISION, Ltd., and PHELP, N. R. July 9, 1945, No. 17471. [Class 65 (ii)] (Also in Group XL] A housing 2 for magnetic deflecting or focusing means comprising a coil or permanent magnet, partially supports the neck 1 of a cathode-ray tube through the intermediary of a ball-and-socket joint 2, 3, 4. This joint comprises a collet 3 split into three equal sections and having a spherical outer surface, and a locking collar 4 and ring 5 having spherical leading surfaces bearing against the collet 3, which screw into the housing 2 as shown.
