    Description: The invention relates to a barrel for a timepiece, comprising a rotatably mounted first barrel drum, which coaxially surrounds a rotatably mounted first spring core, which is enclosed by a helical first tension spring, which with its inner end on the first spring core and is connected with its outer end with the first barrel barrel, wherein the first barrel barrel a gear rim having a gear wheel is rotatably connected.
    The object of the invention is to provide a barrel for a clock of the type mentioned, which has a large power reserve with a small space requirement.
    This object is inventively achieved in that coaxially with the first spring core a second spring house drum is rotatably connected, the coaxial with a radial distance a rotatably mounted second spring core closes, which is surrounded by a spiral-like second spring, with its inner end is connected to the second spring core and with its outer end connected to the second barrel drum, wherein with the second spring coaxially a wheel of a Rade movement of the clock is rotatably connected.
    Although the two tension springs are arranged parallel to each other, but connected in series. This leads to a high power reserve at a largely same moment.
    Compared to a single tension spring, a better height-to-thickness ratio of the tension springs is possible, as a result of which the tension springs are easier to produce at such a high torque. In addition, the life compared to a single spring is much higher.
    For a stable training at lower wall thickness leads, if the first barrel drum and / or the second barrel barrel are pot-shaped with a first and / or second bottom.
    If the first spring core is sleeve-shaped and rotatably mounted on a coaxial bearing extension of the second spring core, both barrel drums are securely guided and thus skewed spring mechanisms at least largely avoided.
    In addition, this also leads to a small size of the barrel.
    It can protrude in a simple construction of the bearing extension of the second spring core with its free end of the sleeve-like extension of the second barrel barrel and rotatably mounted with this free end in a radial bearing.
    For easy coaxial positioning of the sleeve-like extension of the second barrel barrel can be supported axially on the radial bearing.
    In order to achieve a reduction in friction, can be introduced on the inside of the sleeve-like extension derzwei-th barrel drum bearing blocks in which the bearing extension of the second spring core is rotatably mounted.
    For the radial positioning of the first barrel drum, the first barrel drum may have a concentric bearing lug, which is rotatably mounted in a corresponding bearing bore of a fixed Ràderbrücke.
    For proper axial positioning of the first and second barrel drum to each other, the second spring core may have a larger cross-section than the bearing extension, wherein the bottom of the second barrel drum is axially supported at the radial transition of the second spring core of larger cross-section to the bearing extension.
    Is the first bottom of the first barrel drum formed step-like on its side facing the elevator wheel and is formed between the radially outer stage and the elevator wheel radially outwardly open and radially running around the same width as the width of Râderbrücke, into which the wheel bridge with a Rade bridge hole is inserted, the first barrel drum is guided in a simple manner on the fixed Ràderbrücke both axially and radially.
    An embodiment of the invention is illustrated in the drawing and will be described in more detail below. It shows
    Fig. 1 is a plan view of a barrel of a clock;
    Fig. 2 is a section of the barrel of Fig. 1 along the line X-X.
    The illustrated barrel for a clock has a first barrel drum 1, which has a first bottom 2 on its upper side.
    The first bottom 2 is formed on its side facing away from the drum interior of the first barrel drum 1 side-like, wherein the first bottom 2 on its inside the drum closer side has a larger diameter and a smaller thickness than on its inside the drum inside with distant a smaller diameter and a greater thickness.
    On the inside of the drum of the first barrel drum 1 more distant side of the first bottom 2 is a Aufzugzugrad 3 almost the same outside diameter as the first bottom 2 and is fixedly connected by means of several distributed around the circumference arranged screws 22 with the elevator wheel 3.
    In the region of the smaller thickness of the first bottom 2 and the winding wheel 3, an annular guide groove 4 is formed.
    A fixed Râderbrücke 18 of the clock has a Ràderbrückenbohrung 19 with a diameter corresponding to the diameter at the bottom 20 of the guide groove 4 in the radially inner region of the greater thickness, which forms a bearing projection 23.
    Before screwing together first floor 2 of the first barrel drum 1 with the elevator wheel 3, the first floor 2 is inserted with its bearing projection 23 in the Rade bridge bore 19 and then the elevator wheel 3 is screwed by means of screws 21 on the first floor 2. In this case, the first floor 2 comes into contact with the Rade bridge 18, so that the first barrel drum 1 is protected against an oblique position.
    The elevator wheel 3 has centrally a bore 5 into which an annular collar 6 of the first bottom 2 protrudes.
    Parallel to the first barrel drum 1, a second barrel drum 7 is arranged, which has a second bottom 8 on its side facing the first barrel drum 1 side.
    The second bottom 8 has coaxially a sleeve-like extension 22 which projects into the interior of the drum of the first spring house drum 1 and is screwed onto the first spring core 9.
    In the drum interior of the first barrel barrel 1, a first spiral-like first tension spring 10 is arranged, which surrounds the first spring core 9 and is connected with its outer end with the first barrel barrel 1 and with its inner end with the first spring core 9.
    In the drum interior of the second barrel drum 7, a second spring core 11 is coaxially arranged, which is surrounded by a spiral-like second tension spring 12 which is connected with its outer end to the second barrel drum 7 and with its inner end to the second spring core 11.
    The second spring core 11 has a bearing extension 13 of smaller diameter, on which the sleeve-like extension set 22 of the second barrel drum 7 is rotatably mounted.
    With its free end of the bearing extension 13 projects out of the sleeve-like extension 22 and is rotatably mounted in a bearing block of a radial bearing 14. The jewel is fixedly arranged in the sleeve bore 15 of the collar 6 of the first barrel drum 1.
    Axially, the sleeve-like extension 22 is supported with its end face on the bearing block.
    The second bottom 8 of the second barrel drum 7 is axially supported on the radial transition 16 of the second spring 11 to the bearing extension 13.
    In which the elevator wheel 3 remote from the end of the second spring core 11 coaxially a wheel 17 of a Râ-derwerks the clock rotatably disposed.
    The elevator wheel 3 may e.g. rotated by means of a winding crown of the clock and so the two tension springs 10 and 12 are stretched.
