Abstract

863,384. Interrupters. AUTOMATIC ELECTRICAL CONTROL CO. Ltd. Sept. 14, 1959 [June 14, 1958], No. 19103/58. Class 38 (5). [Also in Group XXIV] In a cam assembly for the sequential operation of a series of electric switches each cam comprises a pair of annular plate members 21, 22 formed with internal teeth or serrations engaging corresponding external formations on a bush 17 keyed to the cam-shaft 6. The pairs of plates are held in contact by coil-springs 20 surrounding spacing collars 19, the ends of each spring engaging a plate 21 and a flange ring 18 which may be separate from or integral with the bush 17. The arrangement enables the angular setting of any cam in relation to the shaft to be adjusted and also, by relative angular adjustment of the individual members 21, 22, permits the cam contour 21a, 22a to be modified to vary the period for which the associated switch is closed. As shown, the switches 12 are carried on a cross-shaft 13, each one having a button 31 operated by a spring-arm 32 carrying at one end a roller 34 engageable by a cam lobe. Each switch is provided with a spring-loaded stud 37 whose lower end engages a catch-bar 39 held in retaining-slots by springs 43. A nut 41 at the upper end of the stud 37 permits angular adjustment of the associated switch about spindle 13.
