Definitions

  • This invention relates to devices for winding the springs of spring-driven clockwork mechanisms which are subjected to vibration.
  • Examples of such clockwork occur in the weight mounted so as to oscillate in'response to the vibrations to which'theclockwork is subjected, and connected to the spring winding arbor or other member by which the spring may be wound up through a uni-- directional device which includes one or more cords or threads encircling a pulley and normally kept under tension by means of a spring.
  • a mechanism maybe employed such as set forth-and claimed in the specification of United States Patent No.
  • 1,616,339 and convenientlymay be applied to'the typeof clockwork mechanism which is wound through a going-barrel, and consequently in which the winding arbor is only rotated in one direction during winding and at other times is prevented from rotation.
  • the oscillating weight is preferably mounted to execute its oscillations under the control of one or more springs, so that either the whole weight,'or at least some point on it,
  • a flexible cord, thread, or the like may be i then connected to the said point on the weight and may pass around the pulley, its other end being connected to a spring, which may be anchored to a fixed point on the casing orsupport of the clockwork, or may, in fact,
  • a second cord or thread passmg around a second pulley,or another part of the same pulley, in the-same sense as the 5;
  • first cord may be employed, having one end attached to the Weight near the point at which the spring referred to above it attached," and having its other end connected to a spring venting'the clock from being overwound, and
  • a relieving mechanism is provided which maybe operatedwhen the spring of the clockwork is fully wound either to prevent the weight from vibrating, or toprevent the transmission of its vibrations to the winding mechanism. This may depend upon the epicyclic gear principle being arranged so that when the spring "of the clockwork cannot be wound further, one of the wheels of the reduction gearingis driven slightly as an epicyclic or planet wheeL'and results in a braking or locking device being applied tothe weight, or in relieving one or both of the threads or cords-so that the oscillationsof the gweight are not transmitted to, the winding mechanism.
  • Figure 1 is an elevation of one form" of winding gear looking alongthe axis of the winding arbor of the clock;
  • Figure 2 is an elevation at right angles to Figure 1, partly in section;
  • Figure 3 is an elevation of a modification showing a method of preventing the clock from being overwound, and which may be applied to the construction illustrated in Figures 1 and 2;.and
  • Figures 4 and 5 are views corresponding direction for winding the main spring, and is then held stationary whilethe clock is going.
  • the arbor b is connected to an intermediate spindle 0 by intermediate spur gearing'consistlng of a pinion d and a spur Wheel al having a ratio. of 8:1,.and again, the
  • intermediate spindle c is connected to the driving spindle e by further spur gearing f, again with a ratio of 8: 1.
  • the result is that the-ratio between the driving spindle e and the winding arborbis,64c:1.
  • the vibratory weight consists of a weight ,9 held between two side plates-h, the latter also having between them aspivot'tblock 3' bearing the pivot 70, which "can rock in a
  • the weight g is m supported at their upper endson thefixed casing, and supporting at their lower ends ;pins m extending fromfthe'side plates h of the weight g. If such a clock is carried, for
  • the net result is that there is a driving impulse imparted to'the spindle e in the direction, no matter whether the weight g is moving up or down.
  • the spindle 0 is therefore turned step-by-step in a clockwise direction, as shown by the arrow in Figure 1, and the spring arbor bis turned counterclockwise in order to wind the spring.
  • the tail r is latched by a ball catch r
  • This ball catch 1 is provided with a spring (not shown) so that it holds the tail r firmly until the clock spring is fully wound when epicyclic movement of the plates 1" begins. Similarly it prevents the plate 1" from being rotated too far in the anti-clockwise direction as seen in Figure 8 under the action of the springs when the weight g has been unlocked. This is desirable in order to preventhunting or chattering of the locking mechanism.
  • mecha-- nism may be provided for preventing overwinding of the clock spring.
  • a clutch or other connection may be arranged between the weight and the winding arbor to be disengaged as by slipping when the spring is fully wound.
  • a unidirectional device consisting-of a pulley in driving connection with the spring of the clockwork mechanism, a flexible member encircling said pulley and having both of its ends anchored so as to move with said weight, and a spring inserted in the length of said flexible member to apply tension thereto.
  • Means for winding a clockwork mecha nism comprising the combination of a welght mounted to osc llate in response to vlbratlon and a unldirectional device cons sting of a pulley in driving connection with the 1 spring of the clockwork mechanism, a pair of flexible members encircling said pulley in the same direction and both having their two ends connected to said weight, and springs each in:
  • Means for winding a time-piece comprising arbor of saidtime-piece, a flexible mem ber encircling said pulley and having both ends anchored to said weight, and a spring inserted in the length of said flexible member to impart tension thereto.
