Embodiment Construction

[0017] refer to Figure 1 to Figure 3 , the drive element for the movement of the clock according to the first embodiment of the invention is in the form of a barrel comprising a drum 1 , an arbor 2 and a toothed wheel 3 . The two ends or pivots 4 of the arbor 2 are guided in bearings or stones set respectively in the moving base plate 6 and barrel bridge 7 to allow the relative movement of the arbor 2 relative to the fixed base plate 6 and barrel The cassette bridge 7 rotates about its imaginary axis 8 . The drum 1 and the wheel 3 are mounted on an arbor 2 and are rotatable relative to the arbor 2 about an imaginary axis 8 . For this purpose, the base 9 of the drum 1 has a central hole 10 , the walls of which surround and can slide on the cylindrical portion 11 of the mandrel 2 . In comparison, the wheel 3 has a central hole 12 whose walls surround and can slide on another cylindrical portion 13 of the arbor 2 . The annular surface 14 of the mandrel 2 placed in a plane per...

Abstract

The invention relates to a driving mechanism for a clock movement including a staff (2), a drum (1) and a rotary member (3) mounted on the staff, mutually rotatably mobile and each including gear teeth (24, 23) on the periphery thereof, and first and second stacked hairsprings (25, 26), the outer ends of which are respectively fixed to the drum and to the rotary member, and the bottom ends of which are connected to one another to connect the springs in series. The drum and the rotary member are interlocked at least in the area of the peripheral wall (22) of the drum such as jointly to form a closed case containing the springs.

Description

technical field [0001] The invention relates to drive elements for clock movements. Background technique [0002] In a mechanical clock movement, the drive element is the element that provides energy to the rest of the movement to turn the gear train. The drive element is usually in the form of a barrel with a barrel drum, a helical drive spring or "wind spring" housed within the barrel drum, a barrel arbor and a barrel cover. The barrel drum pivots around the barrel arbor and has teeth on its periphery that, in cooperation with the gear train, drive the barrel drum. The inner end of the drive spring is fixed to the barrel arbor to which the ratchet is fixedly attached, and the ratchet is held by the watch's winding stem (in the case of a hand-wound watch) or the vibrating weight (in the case of an self-winding watch). down) drive. The outer end of the drive spring is fixed to the inner peripheral surface of the barrel drum via a fixable or slidable bracket. The barrel a...
