<p>707,820. Bearings. JUNGHANS, H., and JUNGHANS AKT.-GES., GEB. Aug. 31, 1951 [Sept. 8, 1950], No. 20650/51. Class' 12(1) A shock absorbing bearing for clocks &c. comprises a bearing case 5 into which a bush 4 is slidably fitted without play, a jewel hole 2, and an end stone 3 resting loosely on the edge of the bush. The stone 3 and bush 4 maintain their relative positions when subject to axial shock, by moving in the direction of arrow 6 against a star spring 7, and radial shocks to the spindle 1 force the spindle surface 1b against the stop 5d, the shock being absorbed by flexing of the pivot 1a. Surface 5e forms an axial limit stop, and recesses 5b in the guide surfaces 5a of case 5 permit the entry of tweezers for removing the bush 4.</p> |
