    OSCILLATING DRIVE ASSEMBLY
    The present invention relates to an oscillating drive assembly.
    In one aspect of the present invention, there is provided an oscillating drive assembly that includes a continuous rotary input that drives an oscillating output through a first and a second oscillating drive transmission, the first transmission of oscillating drive creating a primary oscillating displacement of the output and the oscillating drive secondary transmission causing a secondary oscillating displacement of the output which is superimposed on the primary oscillating displacement.
    Various aspects of the present invention are described below with reference to the accompanying drawings, in which: FIG. 1 is a perspective view of a drive assembly according to an embodiment of the present invention, FIG. seen from the end of the drive assembly shown in Figure 1 and Figure 3 is a view from the end similar to that of Figure 2 and showing hidden details.
    The drive assembly 100 shown in the figures comprises a rotary drive input in the form of a drive shaft 1 and an oscillating output in the form of a lever end 6.
    The assembly has the effect of converting a continuous rotary input into a desired oscillating displacement of the end 6 of the lever. The oscillating displacement of the lever end 6 is a composite displacement derived from a first oscillating drive transmission that produces a primary oscillatory displacement and a second oscillating drive transmission that produces a secondary oscillatory displacement that is superimposed on the basic oscillating motion.
    The second oscillating drive transmission can preferably be adjusted to alter the amplitude of the secondary oscillating displacement.
    The end 6 of the lever is formed on a lever 61 which is rotatably mounted via a bearing 8a on a shaft stub 8 fixedly mounted on a rocking body 10. The shaft stub 8 and the bearing 8a define together a first pivot about which the lever 61 oscillates.
    The tilting body 10 is rotatably mounted by means of a bearing 7a on a shaft stump 7 which is fixed in a fixed position on a mounting frame (not shown) for mounting. The shaft stump 7 and the bearing 7a together define a second pivot about which the rocking body 10 oscillates.
    On opposite sides of the second pivot, two cam followers 11, 12 are mounted on the tilting body 10. The cam followers 11, 12 move on respective cams 2, 3 which are mounted on the drive shaft 1 The purpose of the cam 11 is to move the tilting body 10 around the second pivot counterclockwise and the function of the cam 12 is to move the tilting body 10 about the second pivot in the direction of the needles. 'a watch. The cams 11, 12 are consequently opposed and can be driven at high speed to bring about a high speed oscillating displacement of the rocking body 10 and consequently of the end 6 of the lever carried by the rocking body 10. The cams 2, 3 the cam followers 11, 12 and the tilting body 10 constitute the first oscillating drive transmission which provides the primary oscillating displacement of the end 6 of the lever.
    The second oscillating drive transmission is defined by a tilting lever 17 which is pivotally connected to the lever 61 via a connecting rod 15. The tilting lever 17 is rotatably mounted on a support bracket 30, through a shaft 18 and a bearing 18a. The support bracket is in turn fixedly mounted on a frame (not shown). The shaft 18 and the bearing 18a together define a third pivot about which the rocking lever 17 oscillates.
    The oscillating displacement of the rocking lever 17 is preferably created by two cam followers 19, 20 which move on respective cams 4, 5 mounted on the drive shaft 1.
    The cam followers 19, 20 are located on opposite sides of the third pivot, so that the cam follower 19 acts to rotate the lever 17 clockwise around the third pivot while the follower The cam is operative to rotate the lever 17 counterclockwise about the third pivot. Therefore, the cam followers 19, 20 are in opposition and can thus work at high speed.
    The oscillating displacement of the rocking lever 17 is transmitted to the lower end of the lever 61 via a fourth pivotally connected connection defined by a shaft stump 9 and a bearing 9a. The fourth pivot is preferably located near the first pivot so that when the rocking body 10 oscillates around the first pivot, the additional displacement of the end 6 of the lever brought by the rotation of the lever 61 around the second pivot following the moving the rocking body 10 is not important.
    The amplitude of the oscillating displacement imparted by the tilting lever 17 is preferably adjustable by pivotally connecting the link to the lever 17 via a movable pivotable connection. The movable pivotable connection is preferably defined by a threaded shaft stub 16 and a bearing 16a, the shaft 16 being located in a slot 21 formed in the lever 17, so that the distance between the movable pivot and the third pivot can be adjusted. The threaded shaft 16 has a nut 16b located on the opposite side of the lever 17, which can be tightened to fix the longitudinal position of the shaft 16 in the slot 21 or which can be loosened to allow adjustment of the longitudinal position of the shaft 16 in the slot 21.
