Abstract

673,531. Bells. GOODBAR, I. May 4, 1950. No. 11068/50. Class 13. A closed laminated core 1 carries a primary winding 2 on one limb, a secondary winding 3 on the opposite limb and an armature 13 between. Operation of a, bell button 34 closes a circuit through the secondary winding 3, a make-and-break contact 17 and the armature 13, whereby the armature vibrates at a low frequency to ring the bell 12. Operation of a buzzer button 26 closes a circuit through the secondary only to cause the armature to vibrate quickly and act as a buzzer.
