#CMT# #/CMT# The device has a racket (5) arranged with an adjustable orientation on a clockwork movement frame through a beam bridge that swivels a shaft (2) of a rocker (3). A coil (1) comprises an internal end that is integrated with the shaft of the rocker, and an external end (4) that is integrated with attachment units (14, 16). The racket carries clamping units (7, 8) of a terminal portion of the coil to define the length of the coil. The racket defines a support of the attachment units and comprises of guidance units (19, 20) of the attachment units. #CMT#USE : #/CMT# Device for adjusting length of a coil of a beam-spiral type oscillator for clock work movement (claimed). #CMT#ADVANTAGE : #/CMT# The racket carries the clamping units of the terminal portion of the coil so as to improve precision for adjusting length of the coil, reduce negative effects of gravity and avoid the use of an expensive adjustable beam for adjusting length of the coil. The constant radius of curvature of a lengthened opening is same as the radius of curvature of the terminal portion of the coil so as to reduce deformations of coil at the time of the operations of adjustment. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a front view of a beam-spiral type oscillator with an adjusting device. 1 : Coil 2 : Shaft 3 : Rocker 4 : External end 5 : Racket 7, 8 : Clamping units 14, 16 : Attachment units 19, 20 : Guidance units. |
