Abstract: 840,300. Bells. ERICSSON TELEPHONES Ltd. Nov. 1, 1958, No. 35128/58. Class 13. In a magneto bell in which two electromagnets 1 and a permanent magnet 10 are secured by means of a yoke member 5 to form an E-shaped construction, on the free end of the middle limb of which a substantially flat armature 15 is pivoted by a cylindrical pin 14 passing through the limb and the armature, the pin being retained in position by a clip 17, the permanent magnet 10 forms part only of the middle limb. One end of the core 2 of each electromagnet 1 is formed into a circular polepiece 4 and the other end, which is threaded, passes through a hole in the yoke 5 and is retained by a nut 6. The yoke 5 includes a flat rectangular projecting arm 7 provided with two slotted holes which accommodate two brass screws 9. The screws 9 pass through holes in the channel-shaped member 12 and screw into tapped holes in the long limb 19 of a hook-shaped member 11 of mild steel strip, the member 12 clamping the rectangular permanent magnet 10 between the arm 7 and the limb 19. The hooked end 13 of the member 11 has a circular hole in each limb 19 and 20 to accommodate the cylindrical pin 14 on which the armature 15 is pivoted, each ear 27 of the armature 15 having a non-magnetic bush 16 through which the pin 14 passes. The pin 14 has a circumferential slot at each end which co-operates with the corresponding bifurcated end of the U-shaped clip 17. The central portion 21 of the hooked end 13 of member 11 is bent to provide a camber the two plane faces of which are inclined towards the polepieces 4, and the positions of screws 9 in the slotted holes are adjusted so that the spacing of the armature 15 from the polepieces 4 is such that physical contact between the armature 15 and the cambered face of member 11 is prevented when the armature 15 is tilted to co-operate with either of the polepieces 4. A thin resilient rod 25 is welded to the free end of the projection 23, fastened to one free end of the clip 17, so as to be substantially parallel to the striker 18 mounted on the armature 15. The free end of the rod 25 is placed within a selected one of a number of slots 26 provided in a flat rectangular member 24, secured to the yoke 5 by nuts 6, so as to bias the armature 15 towards one or the other of the polepieces 4. The U-shaped clip 17 may be replaced by two circlips.
