Abstract

A regulating mechanism for a watch is provided with a stud holder pivotably mounted under the guide of the outer circumference of the regulating mechanism, the stud holder being provided with a shallow slot on the arm thereof and the regulator having a thin outer circumference inserted in the aforesaid slot and turning under the guide of the circumference of the stud holder, the outer circumference of the slot the outer circumference of the stud holder and the inner circumference of the slot having different radii.

Wilkinson Assistant Examiner-Stanley A. Wal Attorney- Blum, Moscovitz, Friedman & Kaplan ABSTRACT: A regulating mechanism for a watch is provided with a stud holder pivotably mounted under the guide of the outer circumference of the regulating mechanism, the stud holder being provided with a shallow slot on the arm thereof and the regulator having a thin outer circumference inserted in the aforesaid slot and turning under the guide of the circumference of the stud holder, the outer circumference of the slot the outer circumference of the stud holder and the inner circumference of the slot having different radii.
REGULATING MECHANISM FOR A WATCH This invention relates to a regulating mechanism for a thin and adjustable watch.
FIGURES IN DRAWINGS FIG. 1 is a plan view of an ordinary regulating mechanism;
FIG. 2 is a sectional view taken along line A-A' of FIG. 1;
FIG. 3 is a plan view of an embodiment of the invention; and
MG. 4 is a sectional view taken along line 8-8 of FIG. 3. in an ordinary regulating mechanism a stud hold 1 and a regulator 2 are one above the other. The thickness a of the stud holder 1 and b of the regulator 2 have to be sufficient to stand the turning force of regulation. Accordingly, in an ordinary regulating mechanism, the thickness of the stud holder 1 and that of regulator 2 cannot be reduced, and this mechanism cannot be applied to the thin watch because of the total thickness being a+b inevitably.
This invention intends to improve on these disadvantages.
Referring now to the FIGS. 3 and 4, l is the stud holder pivotably mounted under the guide of the outer circumference of regulating mechanism, and provided with a shallow slot la on the arm. 2 is the regulator pivotably mounted under the guide of the outer circumference of the studyholder and provided with the thin circumferential guide section C which is inserted in the shallow slot In of the stud holder 1. 3 is the stud driven in the stud holder 1. 4 is the regulator pin and 5 is the regulator key both fixed in the regulator 2. 7 is the balance cock.
The reason why this construction reduces the thickness of the watch is in the possibility of reducing the thickness of the circumference (this part does not receive the force when the regular 2 is turned). Considering the thickness only, it is possible to remove a part of the circumference 2a, make the regulator as shown by the dotted line and remove the pile of the stud holder 1 and the regulator 2, and dispose them on the same plane, but the mounting of the regulator becomes unstable. According to the invention, the part 2a is left and its thickness reduced as far as possible on processing, and the stud holder 1 and the regulator 2 are combined by this part 20, so that the regular 2 can be held in stable condition.
In this invention, as above mentioned, the stud holder and the regulator can be disposed almost on the same plane and the unstable factor which exists in an ordinary disposition on the same plane disappears, so that the thin and stable regulator can be obtained.
What is claimed is:
l. A regulator mechanism for a watch comprising a balance cock, an essentially disk-shaped stud holder rotatably mounted on said balance cock and including an annular grove therein, a guide flange around a portion of its periphery forming a circumferential channel around said stud. holder between said flange and said balance cock and an arm projecting therefrom, and a regulator comprising an annular mounting section and an annular guide section joining the ends of said mounting section, said mounting section being no thicker than said stud holder and having an inner diameter and a shoulder so dimensioned that said regulator is held rotatably in said channel, and the other of said sections having a thickness no greater than the depth of said groove and an inner diameter such that said guide section fits rotatably within said groove, thereby providing that said regulator is mounted rotatably around said stub holder in a space no thicker than that occupied by said stud holder alone.
