#CMT# #/CMT# The clockwork has a plate (1), an anchor bridge (2) and a balance bridge (3) on which a beam axle (5) and an anchor (4) are swiveled. A beam (6) is fixed in the beam axle, and a hairspring (7) is connected with a ring (7.1). A large plate (9) carries an ankle (10), which cooperates with a fork (4.1) of the anchor, and a small plate (8) is provided with a notch, where the small plate cooperates with a dart (4.2) of the anchor. The hairspring, the ring, the large plate, the ankle and the small plate form a single-piece unit. #CMT#USE : #/CMT# Clockwork for a timepiece (claimed). #CMT#ADVANTAGE : #/CMT# The hairspring, the ring, the large plate, the ankle and the small plate form a single-piece unit so as to reduce overall length of the single-piece unit relative to the space, which is necessary in the existing clockwork construction, where the hairspring, the large plate and the small plate are independent from each other while avoiding diminishing of safety distances required for proper operation of the hairspring and exhaust of the clockwork. The formation of the single-piece removes setting of benchmarking operations, and facilitates an assembly of the beam axle to the hairspring and the two plates by reducing assembly operations, and attaches an end of an external whorl of the hairspring on a piton interdependent of a fixed part of the clockwork, so that the need for adjustment systems can be eliminated, and reduces the number of parts to be assembled. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of a portion of a clockwork. 1 : Plate 2 : Anchor bridge 3 : Balance bridge 4 : Anchor 4.1 : Fork 4.2 : Dart 5 : Beam axle 6 : Beam 7 : Hairspring 7.1 : Ring 8 : Small plate 9 : Large plate 10 : Ankle. |
