    1486674 Dry shavers BRAUN AG 18 Feb 1975 [28 Feb 1974] 6740/75 Heading B4B [Also in Division E2] A dry shaver comprises an inner cutter 19 reciprocated by a motor 11 via a connecting link 13 and a lever 14, the link being coupled to the lever by a joint 17 including a spherical surface 37 on one part and two bearings 35, 36 on the other part embracing the spherical surface so as to thereby permit a wobble action between the connecting link and the lever. The connecting link is provided with a bearing ring 12 joined to the link by reslient arms 33, Fig. 3, an eccentric 31 co-operating with the link to effect the oscillating movement of the lever 14. The link is formed with a fork in which bores 40, 41, Fig. 4a are provided, the edges of the bores co-operating with spherical surfaces 38, 39 formed integrally with a plastics lever 14. In modifications a steel ball (42) is either moulded into the lever 14, Fig. 4b (not shown) or is press-fitted into a bore in the lever, Fig. 4c (not shown). The fork end of the lever is dimensioned such that the spherical surfaces are sprung into their respective bearing seats thus taking up any clearance due to wear.

Cardan movement providing: 6 ts due to the presence of elastic Peremich & 25 between opT), the swarm 4 and the annular part of the connecting rod 5. On the side opposite the engine shaft 24, the rod 5 has a fork 26, formed by two support rings 27 and 28. Between the support rings there is a lower part of the car | A thought which in this place has a slight narrowing. One part of the overhead support 9 has the shape of a spherical (ver1X1Nost.29, in TIO, while the other part is formed by two support rings 27 and 28, covering the spherical surface 29 with K1Ine, with a mechanical zamyzhenie.

    The support rings 27 and 28 are located on the inner surfaces of the forks, 26 of the connecting rod 5 and diametrically opposite to the spherical surface, 29. The supporting
    the rings 27 1 and 2S are parallel between each other and have coaxial cylindrical holes 32 and 33, the diameters of which are somewhat less than the diameter of the spherical surface 29, so that 1 edge of the holes contact

Typically, the diameter of the / versty 32 and 33, s, corresponds to the radius of the spherical surface 29. Or slightly larger than this radius. , ,
    The contact line of the rings 27 and 25 with the spherical surface 29 creates a spherical coius, the apex of which coincides with the center of the sphere, and the angle 1B & taper of the cone should be 60-90 °.
