61	Mainspring mechanism and device having the same	US09978247	2001-10-15	US20030066713A1	2003-04-10	Shoichi Nagao; Eiji Morikuni; Taro Matsunaga
A winding stem (10) is connected to an inner end (11a) of a mainspring (11), and an outer end (11b) of the mainspring (11) is connected to a barrel drum (12). A braking plate (15) is placed inside a braking case (14), and the braking case (14) is filled with a fluid (16). An uneven joint portion (10b) is formed at the lower end of the winding stem (10), and is engaged with an uneven joint portion (15b) of the braking plate (15) placed in the braking case (14). By adopting the above configuration which can simplify the structure of the mainspring mechanism having the braking plate and which can reduce the number of components, the size and production cost of the mainspring mechanism can be reduced.
62	Winder assembly having a spindle	US838054	1992-02-19	US5213181A	1993-05-25	Akihiko Isaka
A winder assembly comprises a spindle provided with a threaded portion, a winder removably engageable with the threaded portion of the spindle and a holder for holding the winder in position when the threaded portion of the spindle and the winder are disengaged from each other, the winder being provided with a perforated guide having a diameter of perforation substantially equally to the diameter of the threaded portion of the spindle. Such an assembly may be suitably used for a music box containing an automatic instrument or the like because it can be easily fitted to a music box and used to operate the music box by simply rotating the winder. Moreover, the winder is provided with a hollow section having a diameter or perforation substantially equal to the diameter of the bolt section of the spindle, the winder can be hardly tilted to damage the stopper, or holder, and separated from the spindle to become an unintended hazard to little children.

75	MECHANICAL TIMEPIECE MOVEMENT WITH POWER RESERVE DETECTION	US15791637	2017-10-24	US20180164743A1	2018-06-14	Ivan VILLAR
The mechanical timepiece movement with power reserve indication includes a barrel system with a winding output connected to a chassis wheel of a differential gear, and with an unwinding output connected to a crown of the differential gear. The differential gear is connected to a power reserve indicator to display the power reserve. The timepiece movement includes at least one locking member disposed on the crown and at least one locking element disposed on the chassis wheel during the rotation of the crown relative to the chassis wheel. The locking member is intended to come into contact with the locking element when the power reserve is at zero, in order to stop the timepiece movement.
76	Barrel with substantially constant torque	US15058777	2016-03-02	US09671754B2	2017-06-06	Patrick Streubel; Silko Goldmann
A barrel for a timepiece. The barrel has a device for limiting the number of running rotations of the barrel, wherein this device still allows any number of winding rotations of the barrel.
77	Barrel	US14383635	2013-03-08	US09335738B2	2016-05-10	Stephane Oes; Laurent Calame
A timepiece barrel includes a drum defining a first compartment and a superimposed second compartment; a first tubular hub secured to a first cover and housed at least partially in the first compartment; a second tubular hub secured to a second cover housed at least partially in the second compartment. Each compartment contains a spring wound into a spiral and an inner first end of which collaborates with the first and second hubs respectively and a second end of which collaborates with the drum. The compartments are open on the side of the covers and the first and second covers are free with reference to the drum and are each provided with peripheral teeth, while the drum has no teeth.
78	Barrel for timepiece	US14753277	2015-06-29	US09285772B2	2016-03-15	Florent Millet; Julien Saglini
A barrel for timepiece movement, comprising a barrel shaft (20) around which is arranged, in a rotationally mobile manner, an assembly comprising a drum (30) and a cover (40) delimiting a housing (50) for receiving a barrel spring (51), the drum (30) and the cover (40) each having a wall (31, 41) extending from a peripheral end (34, 44) of the barrel to a central end of the barrel at the level of the barrel shaft (20), wherein at least a part of at least one of said walls (31, 41) has a variable thickness which increases continually with distance away from the peripheral end of the barrel.
79	Watch with improved power reserve	US14514574	2014-10-15	US09063515B2	2015-06-23	Cedric Decosterd
Mechanical timepiece movement, including at least one energy storage means fed at the input by a ratchet driven by one winding mechanism and at the output powering a going train. The movement includes first energy take-up means connected to at least one wheel set of this going train by at least a first elastic connection, this first energy take-up means cooperating with at least one wheel set driving this ratchet, in mesh with this ratchet for powering this energy storage means by reinjecting part of the energy taken up by this energy take-up means, this wheel set driving this ratchet being uncouplable under the action of at least one uncoupling mechanism active during the operation of this winding mechanism.

A timepiece barrel includes: a drum (14) defining a first compartment (16a) and a second compartment (16b) which compartments are superposed; a first tubular hub (22a) secured to a first cover (24a) and housed at least partially in the first compartment; a second tubular hub (22b) secured to a second cover (24b) housed at least partially in the second compartment. Each compartment contains a spring (18a, 18b) wound into a spiral and an inner first end of which collaborates with the first and second hubs respectively and a second end of which collaborates with the drum (14).
