Abstract

22,085. Cortland, H. Sept. 23. Make-and-break switches, mechanical.-In a transmitting-apparatus for a fire-alarm system, the weight - driven notched disk 21 operates make-and-break contacts 48, 47 during its rotation. The contact-arms 37, 38 are separately pivoted in such a manner that the contact 48 wipes over and raises the contact 47.
