Abstract:
A mechanical timepiece movement, including a spiral spring, a barrel, the spiral spring accommodated in the barrel as an energy storage, the barrel transmitting energy of the spiral spring by a gear train to an oscillator, the oscillator including a balance as a regulating device, and a mechanism configured to reduce a torque generated by the barrel to reduce loss of energy stored in the spiral spring.
Abstract:
The watch movement comprises a motor barrel (102), a fusee (104) having a main surface that has a spiral groove (148), means (192) for winding the movement arranged to drive the fusee, a going train (200) arranged to be driven by the fusee, and a wire (106) extended between the fusee and the barrel. The watch movement additionally comprises a fixed guide (155; 255) and a winding roller (157; 257) mounted to slide on the fixed guide, wherein the winding roller is arranged to guide the wire when the fusee turns and to simultaneously assure the insertion of the wire into the groove (148) and its removal therefrom.
Abstract:
A mechanical watch comprises a motive spring in a first spring barrel and a mechanical and/or automatic winding device. A second spring barrel and a differential having three drive trains are provided, wherein the train connected to the winding device acts on the first and second spring barrels in the same direction.

666,772. Clocks and watches. ANDREWS, G. S. Aug. 16, 1948 [Aug. 28, 1947], No. 21573/48. Class 139. In a timepiece the curb pins are moved along an arc of the hairspring as the mainspring unwinds, which arc is adjustable in length. In one embodiment (Fig. 1) the curb pins 26 are carried by an arm 27 pivoted on the balance staff 22 and frictionally connected to one end of a lever 28, the other end of which is urged against a helical spring 34 rotated through gearing by the mainspring. The top end of the spring 34 is adjustable and as the arm 27 may be moved relatively to the lever 28 the length of the are of movement of the curb pins may be initially set. In another embodiment, not shown, a spiral spring is used in place of the helical spring. In another example (Fig. 7) the arm 78 carrying the curb pins 77, frictionally engages a lever 79 connected by a pin and slot connection to a lever 83 having a pin 82 constantly urged against a cam 81 driven from the mainspring. The pin 88 is adjustable along the slot 87 of the lever 83 for setting of the arc of movement of the curb pins. In another example (Fig. 9), the arm 104 carrying the curb pins 103 is frictionally connected to a lever 106 having an adjustable tip 107 urged against a gear wheel 110, which is moved vertically along a screwed shaft 109 as the mainspring unwinds. In another example (Fig. 10), not shown, a gear wheel movable along a screwed shaft as the mainspring unwinds carries a conical cam 129 which co-operates with a pivoted lever of adjustable length which lever moves the lever which is frictionally connected to the arm carrying the curb pins. In another example (Figs. 11 and 12), a spiral cam 146 rotated by the mainspring is vertically adjustable along a shaft 145 and moves a lever 150 frictionally connected to the arm 149 carrying the curb pins 148.
Abstract:
A setting machine (1000) for making a setting and/or adjustment on an assembly (1) attached to a receptacle (10), including a positioning module (100) to move this receptacle (10) on command from control means (3000) to convey it into a setting and/or adjustment position below an acquisition module (200), which includes measuring and/or testing means for determining the spatial position of the receptacle (10), and including a setting and/or adjustment module (400) for making a setting and/or an adjustment with motorised axes for moving, opening and closing, in a clamp plane perpendicular to a clamp rotation direction (DF, DG), a clamp (600) arranged to drive or deform a mobile component or a component included in such an assembly (1) borne by a receptacle (10), and method for using such a setting machine for setting and/or adjusting at least one horological component.
Abstract:
The mechanical timepiece movement with power reserve indication comprises at least one barrel system connected to a winding wheel of a differential gear and an unwinding wheel of the differential gear. An intermediate wheel of the differential gear is connected to a cam wheel set to drive it in rotation via a reducing stage. A rack, which acts on a power reserve indicator, is in contact with the cam wheel set. When the power reserve is at zero, a locking part of the rack comes into contact with a locking member to lock the movement at an unwinding output of the barrel system or in contact with the unwinding wheel of the differential gear.
