BARREL COMPRISING ADDITIONAL RESILIENT ENERGY ACCUMULATION MEANS Russian patent published in 2016 - IPC G04B1/16 

FIELD: mechanisms.

SUBSTANCE: present invention relates to barrel (11, 21) having box (13, 23) for receiving pivot shaft (15, 25) and at least one spring (17, 27, 37, 47, 57, 77), said at least one spring spiral being mounted between internal wall of box (13, 23) and outer wall of pivot shaft (15, 25), and can be twisted to accumulate mechanical energy. According to invention barrel (11, 21) further comprises device (12, 22, 22') to increase torque of said at least one spring, including additional resilient means (14, 24, 24') for energy accumulation, which are provided in addition to spiral shape of said at least one spring, wherein said resilient means are connected to said at least one spring so that torque of barrel (11, 21) can be customised in accordance with tension of turns of said at least one spring.

EFFECT: invention involves field of clock mechanisms.
