Definitions

  • the invention consists in the provision ot a supporting member fixed to the wrist strap of the watch and to which the watch caso is connected by means ot' pivoted links permitting the watch case to effect an alternating movement relative to the supporting member, an actuating mechanism being provided between the supporting member and the driving spring to eiiect winding ot the spring owing to the influence ot the said relative movement.
  • Figure 1 is a. plan view of a wrist watch in accordance with the invention.
  • Figure 2 is a side elevation of the watch.
  • Figure 3 is a section showing the watch movement from the side ot the bridges.
  • Figure 4 is a section along the line ⁇ IV- IV ot Figure 3.
  • the movement 1 is located in the watch case 2 ot rectangular shape, mounted on a cradle-like supporting member 3 destined to rest on the wrist of the bearer of the watch.
  • the connection between the watch case and the supporting member is made by means of two pairs of links 4 and 5 adapted to pivot in vertical planes parallel to the longitudinal sides ot the watch case.
  • the two ends of the supporting member 3 are bent up and to each end is secured one end of the wrist strap 6.
  • the links 4 ot the first pair are each connected on the one hand to an aXis 7 fixed t-o the cradle 3, and on the other hand by means of pins 8 to the longitudinal sides of the case 2.
  • the links 5 of the second pair have each one end pivoted on an axis 9 ot the cradle 3, and their purpose of Serial No. 573,980, and in Switzerland September 23, 1931.
  • ends 10 are rio'idly connected to a shaft 11, penetrating the case 2 and the movement 'l in which it is rotatably mounted.
  • the shaft 11 is provided with a crank 12 adapted to rotate in an empty space 1 provided in the movement.
  • a spring pawl 14 having its other end 15 cooperating with the toothing 1G ot a ratchet wheel 17 mounted on a pinion carried by the spring drum shatt.
  • a rota ining pawl 18 cooperates with the ratchet 1T, while 19 indicates a spring fixed to the movement 1 and to the spring pawl 14 :tor the maintaining the end 15 ot the pawl constantly in contact with the ratchet 1 f
  • the case 2 enclosing the movement 1, and mounted in the described manner on the supporting member 3 can thus move relative to this member owing to the action ot shocks produced bythe. movements of the arm of the watch bearer.
  • the case is guided in its movements by the two pairs ot rods 4 and 5 and can thus reciprocate between the limits of its two eXtreme positions shown in full and dotted lines in Fig. 2.
  • the shaft 11 turns slightly in the direction of the arrow f, about the axis 9 into the position shown in dotted lines in Fig. 2, whereby the spring pawl 14 is moved trom the right to the lett in Fig. 3 relative to the watch and drives the ratchet wheel 17, to wind the main spring.
  • the shaft 11 also turns in opposite direction to the arrow f and moves from the lett towards the right sliding over the teeth ot the ratchet which is retained in its position by the pawl 18.
  • the two ends 20 of the strap 6 are secured in such a manner to the supporting member 3 as to penetrate into the cradle and to act as shock absorbers for the movements of the watch and also prevent any noise, the
  • the movement may comprise any known friction connection between the main spring and the drum.
  • An automatic winding device for the driving spring of timepieces comprising a supporting member for the timepiece, a pair of connecting links pivoted to the timepiece and to the supporting member whereby the timepiece'may execute an alternating move- '"rent relative to the supporting member, a rotatable operatiiig member carried ⁇ by the timepiece and connected to the driving spring, a pair of connecting Alinks pivoted to thefsupporting member and secured to a shaft rotatably mounted in the timepiece, 'and 'means for operatively connecting said sha'ftto 'said operating member and adapted to rotate said operating member upon relative movement ⁇ between the timepiece and the supporting member.
  • a spring driven wrist watch having a watch case including 'a movement, a cradle-'like supporting member for the watch case secured to the wrist strap, connecting links pivoted to the Watch case and tothe supporting memberfwhereby the watch 'case may execute 'an alternating movement relative 'to the supporting member, a rotatable operatin member for fthe driving "sp carried the watch case, and actuating connections between said operating member and said 'supporting member to 'rotate the operating member upon relative movement bet'ween'the watch case ⁇ and 'the supporting member, the ends 'off the Wrist strap penetrat'ng V'into the interior of the cradle-like supporting 'member to act as shock absorbers for 1vthe 'movements of the watch case.
