Abstract
765,995. Electromagnetic interrupters. MALLORY & CO., Inc., P. R. March 25, 1955 [Nov. 10, 1954], No. 8729/55. Class 38(5) The vibratory contacts 30, 31, 33, 34 and co-operating fixed contacts 17 are formed of molybdenum spring strip, the contact making and breaking taking place between the surfaces of the outwardly bent strip ends. The contacts 30, 31 are fixed to an armature-carrying steel reed 16 by a rivet 32 passing a reed hole 23, and the contacts 33, 34 are secured by a rivet passing through a larger reed hole 24, interposed spacers 36, 37 insulating the contacts 33, 34 from the reed. A flexible steel arm 38 secured against the reed 16 by the rivets 32, 35 caries a contact 39 co-operating with a contact 42 carried by the magnet frame 10, the contacts being in the circuit of a coil 12 energizing a hole piece 13 to attract the armature 20. The contacts 17, 30, 31, 33, 34 are made more compliant by slots 46 and notches 47. The reed 16 is fixed in the stock 11 by an integral limb 25 and by a separate strip 27 having an aperture 29 receiving the rivet 35 whereby the strip is insulated from the reed by the spacer 37. Specification 515,797 is referred to.
