Abstract
1483487 Timepiece regulators ETA A G EBAUCHES-FABRIK 20 Nov 1974 [3 Dec 1973] 50266/74 Heading G3T In a regulator comprising an annular part 1, e.g. for rotation about a balance bearing, and an arm 2 the outer end of which is blanked and bent to form two elements 4, 6 defining an aperture 3 within which the outer turn 10 of a balance spring can oscillate freely when the index is in use, the end portion is bent into a plane parallel to the balance axis and at an angle to a radius of the annular part passing through the aperture 3 so that the parallel edges 11, 12 of the aperture form limiting elements for the spring's oscillation. The end portion is shown in dotted line in Fig. 2 in the position after blanking but before bending. The aperture 3 may be a closed aperture Figs. 4-6 and 8 (not shown) or the limiting elements may form an open fork Fig. 7 (not shown). The end portion may be formed to facilitate adjustment of the spacing of the limiting elements by twisting.
