Definitions

  • My invention relates to improvements in the mainsprings of watches and clocks, and the object of my improvement is to obtain a more constant and increased driving-power.
  • I. attain this object by employing a helical spring, which I locate circnmferentiall y within the case and around the works, which are encompassed by it. I am thus able to use a very long helical spring, which will store up a considerable amount of power. To wind up such a spring in order to store up the power for driving the train, it may be either compressedlongitudinally or excessively twisted.
  • the helical spring a is attached at one end to the stem f and at the other end to the beveled wheel c.
  • a ratchet, g which is arrested by the click h.
  • d is a second beveled wheel, with which the wheel c engages, and which transmitsthe force of the spring ⁇ a', twisted by winding up the wheel-work.
  • the spring can be coiled within the clock or watch case in any way that least interferes with the watch mechanism, and I preferably arrange the spring so thatit encompasses the works, passing clear around the watch. very long helical spring can be used.
  • the spring is held in its proper place by means of the guide-pinsp, the spring, commencing with the stem end, passing under the irst guide-pin, so as not to give it too great a bend, and then outside ofthe other pins close against the case.
  • the spring is also wound up by turning the stem j'.
  • a pinion, c fixed to the inner end of the stein f, engages with a gearwheel, d, which has a projection or finger, c.
  • the helical spring a is placed inside an annular channel, Z), through a slit of which passes the finger c, thus abutting against one end of the spring a, the other end bearing against vthe bottom plate of the annular channel.
  • the wheel d is connected with the main shaft of the wheel-work by a suitable ratchet device, the wheel-work will be moved by the compressed spring a.
  • a mainspring consisting of a helical spring coiled circumferentially within the case, substantially as set forth.
  • the combination with a helical mainspring coiled circumferentially within the case and operatively connected with the timeindicating mechanism, of a revoluble stem projecting from the said case and connected with the said spring,t'or storing up the power, substantially as and for the purpose set forth.
