667,475. Bearings. MORF, E. Feb. 28, 1950 [April 14, 1949], No. 5100/50. Class 12 (i). In a bearing for gear-wheels in watches and other precision apparatus, the walls of the space receiving the pivot 8 of the gearwheel are only in part made of non-metallic jewels. The bearing may comprise a jewel disc 9, Fig. 3, having a cut-out 12 on its circumference, forced into a metallic setting 10. The pivot 8 normally engages the jewel under the action of a force F which acts on the gear-wheel. The cut-out may be V-shaped. In a modification, the bearing comprises jewel members 14, 15 contacting each other and forming together with the metallic setting 13, a space for receiving the pivot. In a further modification, for a pivot of larger diameter, the jewels may be arranged in separate holes in the metallic setting, each contacting the pivot.
