PATENTEU M25197] INVENTOR. ndre HEYLAN 'ROC HAT cam/1mm (Zia s.
The present invention relates to a regulator-assembly for a timepiece in which the regulator has a catch engaged in the groove of a tangential screw to which is screwed in the frame of the clockwork in such a way that the angular position of the regulator is modified by the adjusting of the screw.
Regulator-assemblies of the above-mentioned type are known. Several solutions have been proposed so that the catch of the regulator engages itself without any play in the groove of the screw so that the displacement of the screw, when carried out alternately in one direction or in the other, immediately produces corresponding displacement of the regulator, without to lost motion.
The object of the present invention is to provide a particularly simple solution to this problem.
The regulator-assembly according to the invention is characterized by the fact that the catch of the regulator is constituted by a thin elastic tongue urging to itself, by its own elasticity, againstthe bottom of the groove, the two terminal faces of the groove being frustoconical and opening towards the outside, the width of the bottom of the groove being less than that of the tongue, the tongue bearing simultaneously on both the frustoconical surfaces the displacements of the screw, when carried out alternately in one direction and the other, producing corresponding displacements of the regulator, without idle running.
The drawing shows, by way of example, one embodiment of the invention.
FIG. 1 is a plan view, seen from sembly for timepiece,
FIG. 2 is a sectional view taken along line ll-ll of FIG. 1, an on enlarged scale, same elements not shown in FIG. 1 having been represented in this FlG.; and FIG. 3 is a section on the line lll-Ill of FIG. 2.
The regulator-assembly shown comprises a holder 1 for the balance spring stud rotatably mounted on a top balance-endpiece, fixed on the balance cock 3, and a lug 1a of which has an edge 1b the exterior face 4 of which is cylindrical. The balance spring, designated by 5, is pressed against this face 4 by a plate 6, screwed by a screw 7.
below, of a regulator-as- The regulator is made of two pieces, namely an annular piece 8 rotatably mounted on the stud holder 1 and an annular piece 9 rotatably mounted on annular piece 8; the piece 9 has a lug 9a carrying the adjustment-pins 10.
The piece 8 of the regulator has a thin elastic tongue 8a engaged in a groove 11 by a screw 12 tangentially disposed with respect to the regulator, screwed in the rim 1b of the stud holder 1. The two axial faces 13 of the groove 11 are frustoconical, opening towards the outside, the width of the tongue being greater than the width of the bottom of the groove. Consequently, the tongue 8a bears simultaneously on the two frustoconical surfaces 13 so that the displacements of the screw 12, when motivated alternately in one direction and in the other, immediately produce corresponding displacements of the regulator, without lost motion.
